Process for the transmission of data with a high priority

The present invention relates to a method for the transmission of first data with high priority and second data with lower priority, with a data block of second data being provided for transmission at a time t in a telecommunication device and t being transmitted at this time Telecommunication device first data are already sent or are intended to be sent.

Such methods are known from the prior art. For example, a so-called "Fast Associated Control Channel" (FACCH) exists in the American mobile radio standard "IS-95". This is a data transmission channel via which both high-priority voice data and lower-priority messages, so-called "FACCH messages", can be sent. Further information on this standard can be obtained, for example, on the Internet at "www.tiaonline.org". According to the standard mentioned, the following procedure is provided: If a FACCH message is to be sent while voice data is already being transmitted via the FACCH channel, the voice transmission is briefly interrupted in order to send the FACCH message. So that the receiver does not experience too much disruption of the speech data, a method for obscuring the speech gap is implemented in the receiver. Nevertheless, sending the FACCH message leads to a significant deterioration in the voice quality.

Furthermore, a method is known from European patent EP 0 799 534 B1, in which both high-priority voice data and lower-priority FACCH messages can be transmitted via a communication channel. The procedure provides that a time window is assigned to FACCH messages to be sent. If voice data is already being transmitted at the planned time of transmission of the signaling data, it is waited within the time window whether the voice transmission is ended, interrupted or suspended. If this is the case, the signaling data are sent after the end of the voice data transmission. If the voice data transmission is not suspended within the permitted time window, the signaling message is sent as described in the previous section after the time window has expired and the voice data transmission is briefly interrupted. Furthermore, it is proposed in the above-mentioned method to send the signaling data immediately if no voice data is transmitted at the time originally intended for the FACCH message. In the present description, the termination, the suspension and the interruption of a data transmission are treated as synonyms.

It is a problem of the prior art that the known method has a substantial probability that lower-priority data will be overlaid on higher-priority speech data, which can significantly reduce the speech quality.

It is therefore an object of the present invention to provide a method which enables improved transmission quality in the transmission of high-priority data with simultaneous presence of lower-priority data.

The object is achieved by a method for transmitting high-priority first data and lower-priority second data, second data being provided for transmission at a first transmission time t in a telecommunication device and already being transmitted by the telecommunication device at this first transmission time t first data will be sent or scheduled for sending and a time profile of importance values is also assigned to a time profile of first data and a second transmission time t _{2 is determined} for sending the data block of the second data using at least one of the importance values. The second data can be designed, for example, as a data block of second data.

The fact that the chronological course of first data is associated with a chronological course of importance values makes it possible to assign values to the first data which, for example, characterize the first data or respectively indicate a current priority. This enables the high-priority first data to be better characterized than the assignment of a single priority value. The characterization of the time profile of the high-priority first data makes it easier to find an advantageous second sending time t ₂ for sending the second data, so that the transmission of the first data is affected as little as possible.

For example, it may be that less data has to be transmitted for a certain time within the transmission of the high-priority first data or that data of less relative importance has to be transmitted. In this case, the proposed method makes it possible, for example, to use such phases within the transmission of the first data, which has a high priority, and thus to impair the transmission of the first data as little as possible. Therefore, the proposed method enables an improvement in the transmission quality in the transmission of first data which is given high priority over the prior art.

The prioritization of the first or second data can be a temporal prioritization, for example. For example, high-priority data can be time-critical data, ie data that must be transmitted as immediately as possible. An example of such data can be voice data, for example, since delays have a very strong effect on voice data and can even make them incomprehensible. Time-critical data can for example also in the real ^¬ time control of machines, vehicles and equipment incurred in which delays in control signals or the transmission can cause the machine to damage or hazards of feedback information.

Less time-critical data can be, for example, signaling data or the transmission of packet data, for example from the Internet for displaying a homepage, which do not impair the user even with a small time delay.

The prioritization can also include a qualitative prioritization. For example, high-priority data can be data that have to be transmitted with a very high quality standard, while lower-priority data can be data for which the quality standard is lower and for which, for example, a bit error rate can also be somewhat higher. Of course, prioritization can also combine temporal and qualitative prioritization.

A telecommunications device can be, for example, a telecommunications terminal which is connected to or can be connected to a fixed telecommunications network, such as a telephone network. Such telecommunication devices can be, for example, telephone devices or a computer with a modem for a telephone network or an ETHERNET interface, or even just a corresponding interface card. Furthermore, telecommunication devices can be telecommunication terminals for coupling to a mobile telecommunication network. These can be end devices for a cellular mobile radio network (e.g. GSM, UMTS, CDMA 2000, ...) or to connect to a local radio network (e.g. Bluetooth, WLAN, ...). Furthermore, such end devices can be designed as corresponding radio modules, such as are used, for example, for remote reading of meters and devices and for remote control of such machines and devices, or as are available for computers for coupling to a mobile telecommunications network. A telecommunications device can furthermore also be a data processing device which comprises a telecommunications module (for a fixed or a mobile radio network).

Furthermore, telecommunication devices can also be part of the network architecture of a telecommunication network. For example, in a mobile radio network these can be base stations with corresponding control devices (e.g. GSM: base station and base station controller / UMTS: Node B and "Radio Network Controller" (RNC)). In a WLAN, for example, this can be the transmission unit with the associated control device. Corresponding control devices in a fixed telecommunications network can also be telecommunications devices in the sense of the invention mentioned.

The assignment of a temporal profile of validity values to a temporal profile of first data can take place, for example, in such a way that all first data or a selection of first data is assigned an importance value, which is obtained, for example, directly from the first data and / or the already transmitted first data can be. Furthermore, the temporal course of importance values can also be a time-dependent function, which can depend on first data or values characterizing the first data. However, such a function can also have a time profile that is generally independent of the first data. Furthermore, it can be provided that only parts of the first data are assigned an validity value, other values of the first data can then be assigned importance values, for example by interpolation or extrapolation can be determined from the importance values assigned to the parts of the first data.

A transmission time t ₂ for sending the second data can be determined, for example, by sending the second data as soon as an accuracy value assigned to the first data, or an importance value obtained by the interpolation or extrapolation described above, meets a predetermined condition. Such a condition can include, for example, exceeding or falling below a certain predetermined threshold value.

Furthermore, a condition for sending the second data can also be obtained from a chronological course of the importance values. For example, it can be provided that the second data is sent as soon as the validity value has changed by a certain predetermined amount or has a predetermined rate of change over time.

The method described above can be used in particular for the transmission of first high-priority and second lower-priority data if these are sent over the same telecommunications channel. In this case, the sending of the second data could, for example, lead to an interruption and / or a shift in the transmission of the high-priority first data. However, the above method can also be used advantageously if first and second data are sent via different telecommunication channels, since this can be used, for example, to ensure that the received data rate is as uniform as possible at a receiver. In radio networks, for example, it can be achieved in this way that the reception field strength at a receiver is as uniform as possible. Furthermore, a more uniform course of the transmission power can also be achieved on the transmission side.

In an advantageous embodiment of the method described above, it can be provided that a time span of length dT is started at time t, at which the sending of low-priority second data is provided. By means of such a time period dT, it is possible, for example, to define a tolerance range for sending the second data, which can determine a maximum time shift in the sending of the data block of the second data. For example, it can be provided that within the time period of length dT, the conditions for sending the second data are different than after the time period dT has expired. In particular, provision can be made for the conditions for sending the second data to be relaxed after the time period dT has elapsed.

For example, it can be provided that if the second data has not already been sent within the time period dT, it will be sent after the second time period dT has elapsed, regardless of the validity values. Then the chronological course of the first data has e.g. no longer affects the sending of the second data. Furthermore, it can be provided that the second data are sent immediately after the time period dT, if they have not already been sent within the time period dT. In the latter case, the time period dT would actually specify the tolerance time in which the second data must be sent.

One possibility for realizing the method described above is that the time period dT is or is assigned an importance threshold value function at least in sections, and that the second data continue to be sent as soon as within the time period dT at least one importance value below a corresponding value of the importance -Threshold function lies. The importance threshold function thus offers the possibility, depending on the application, for example of a time-constant threshold for sending the second data within the To set time span dT, or to provide a time-varying threshold. In the case of an activity threshold value function that is constant over time, the second data would then be sent, for example, as soon as at least one important value of the first data drops below the threshold. In the case of a time-varying weight threshold value function, it can be provided, for example, that a relatively low threshold value is provided at the beginning of the time period dT, so that the second data are only sent as soon as the first data have a relatively low importance value. Furthermore, a higher threshold value can be set towards the end of the time period dT, which allows the second data to be sent as soon as a higher importance value is reached.

In particular, if it is intended to send the second data immediately after the end of the time period dT, raising the importance threshold function at the end of the time period dT may make it possible to determine a more optimal send time t ₂ . After the time period dT first data has passed, data with a high importance value could then be sent, and this might then have to be overlaid with second data.

There may further be provided that the second data is not sent until dt within the period dT importance values for a minimum period below the entspre ^¬ sponding Importance value of the threshold function is located. This can be used, for example, to prevent the second data from being sent because of a brief fluctuation in the importance value, although this would not be appropriate according to the general chronological course of the importance value.

In a further embodiment of the present invention it can be provided that a importance threshold function for determining the time t ₂ for sending the two th data is provided and that the second data will continue to be sent later than as explained in the preceding paragraphs if the importance values decrease at this point in time. It can thus be provided to send the second data with a delay after a delay period after at least one importance value has fallen below a corresponding value of the importance threshold function if, at the time when the at least one importance value is below the corresponding value of the importance threshold function. Threshold function is, the importance values decrease in time.

This embodiment of the invention enables a further improvement in the quality of the transmission of the high-priority first data and the lower-priority second data, since if the importance values decrease, it is to be expected that at a later point in time even lower importance values will be available and accordingly a later one The time may be more suitable for sending the data block of the second data. The delay period can, for example, be a fixed, predetermined value or, for example, be based on the temporal drop in the importance values.

Corresponding to the procedure described in the two preceding paragraphs for time-decreasing importance values, the reverse procedure can be used for time-increasing importance values. It can be provided that the second data is sent at a point in time that is before the point in time that would result from the important threshold value function and the corresponding important values. In this case, it can be provided, for example, that when the importance values increase, the second data is already sent if the importance values are still an additional value above the corresponding one

Value of the importance threshold function lies. This additional value can in turn be predefined, for example or result from the temporal increase in the importance values.

Since it is to be expected that the importance values will increase at a later point in time when the importance values increase, the method described above can be used to ensure that the second data are sent in good time before the high importance values are reached.

In order to take into account the increase and decrease in the importance values when determining the sending time t _{2 of} the second data, the time period dT can be assigned, at least in sections, a threshold value initial function, from which an importance threshold value function is determined or can be determined. It can be provided that in the area of temporally increasing importance values the importance threshold function is increased compared to the threshold value initial function and / or in the area of temporally decreasing importance values the importance threshold value function is decreased compared to the threshold value initial function. With this embodiment, it can be achieved that if the importance values increase in time, the triggering time for sending the second data tends to be shifted to earlier times, since the importance value function typically drops below this function earlier and therefore the value falls earlier due to the local increase in the importance threshold value function second data are sent earlier. This makes sense, since with increasing importance values it can be expected that the importance values will be higher at a later point in time and the second data should therefore be sent as early as possible.

The reverse applies to decreasing importance values. It is to be expected here that lower importance values will be available at later points in time, and therefore the second data should rather be sent later. This can be done in advance lying embodiment can be achieved in that the importance threshold function is lowered compared to the threshold value initial function in the event of decreasing importance values. This lowering means that a smaller value than originally intended is required in order to trigger the sending of the second data, which is typically the case at a later time when the value of the value drops.

The amount by which the threshold value initial function is raised or lowered can be, for example, a fixed, predetermined amount or an amount that is based on the degree of increase or decrease in the importance values.

Furthermore, instead of adapting an initial threshold value function to the temporal profile of the importance values, the temporal profile of the importance values can directly influence the determination of the importance values. This can e.g. can be achieved by including validity values from the past when determining an importance value. This can be achieved, for example, by assigning an invalidity value to a specific point in time, which is calculated as the mean value from an important value measured at that point in time with important values from the past. The importance values determined in this way could then, for example, be compared again with an importance threshold function.

The importance threshold function and / or the threshold value initial function can for example be monotonically increasing or strictly monotonically increasing over time. The functions mentioned are monotonically increasing in time if they either increase or are constant over time. Due to the temporally monotonous increase or the strictly monotonous increase in the importance threshold function and / or the threshold value initial function, for example achieved that the conditions for sending the packet of the second data are systematically facilitated by systematically raising a threshold value, below which the importance value must fall in order to trigger the sending.

The importance threshold function or the threshold start function can be, for example, continuous functions or functions with jumps. In particular, they can be designed, for example, as a step function with one or more steps. For example, the importance threshold value function can be designed as a step function which has a relatively low importance threshold value in a first part of the time period dT and has a higher importance threshold value in a second section of the time period dT.

The high-priority first data can be transmitted, for example, in a packet data format or in a real-time transmission format. Packet data formats are, for example, the IP protocol in the fixed network area and, for example, the GPRS protocol in the mobile radio area. Real-time transmission formats are generally used in the telecommunications sector for voice transmission, in which a transmitter is connected directly to a receiver via one or more switching centers. Real-time transmission formats are used both in mobile radio and in the fixed network area.

The method described above is suitable, for example, for the transmission of voice data as the first highly prioritized data. The voice data can be transmitted, for example, in a real-time transmission format or also in a packet data transmission format (e.g. "Voice over IP" (VoIP)).

When using voice data as high-priority first data, the importance value assigned to the voice data can, for example, be assigned to the voice data. neter voice activity value. In digital voice transmission methods, such as those used in mobile radio, a so-called "voice codec" is often responsible for converting analog voice signals into digital signals. Such a voice codec, such as, for example, the so-called "adaptive multi-rate codec (AMR codec)" used in mobile radio, has the possibility of such a voice activity value, for example, using the volume and / or a spectral distribution and / or a time profile the voice data to certain. Such a speech codec is also able to analyze whether speech data is available at all or not. When using such a voice codec, it can be used, for example, to determine whether voice data is being sent at all at the point in time t at which it is intended to send a data block of second data. Furthermore, the speech codec can be used to continue to assign a speech activity value to the sent speech data.

If the method described above were applied to voice data as the first data and the voice activity was used as an importance value, the proposed method would achieve the fact that second data with lower priorities can preferably be sent at times of relatively low voice activity, which means that the reception of the voice data is relatively little impaired. With such a method, for example, a significant improvement in the transmission of voice data while simultaneously sending lower-priority second data can be achieved.

The lower-priority second data can be, for example, signaling data in the telecommunications network with which various units in the telecommunications network, for example a network controller and a terminal, coordinate technical boundary conditions for data transmission (for example assignment of channels, codes, transmission rates, transmission formats, etc.). Furthermore, lower priority based second data also include packet data. Such packet data can, for example, also include signaling data or also written messages, e-mails or similar messages; packet data can also be data which are downloaded from the Internet via the iP protocol (for example a homepage, a file or an application).

However, first, highly prioritized data can also be designed as packet data. For example, packet data protocols can be used in the control or regulation of devices or machines. With these, however, it is very important that they arrive at the controlled device as soon as possible, or that the feedback from the respective devices or machines arrive back at the controller in a timely manner in order to achieve the best possible control. Furthermore, high-priority packet data can also e.g. occur when using online games, e.g. in combat situations it is necessary that the relevant information reaches the other players as quickly and qualitatively as possible in order to achieve a correspondingly good gaming experience.

The above-mentioned object is further achieved by a telecommunications device with a control device and a transmission device, the control device being set up to carry out a method according to one of the preceding claims. As already mentioned above, such telecommunication devices can be a wide variety of telecommunication terminals for fixed or radio networks. Furthermore, such telecommunications devices can also be corresponding transmitting and / or receiving devices within the network architecture of such networks.

Further advantageous refinements can be found in the subclaims. The invention is explained below by way of example with reference to the following figures:

1 shows a schematic representation of a mobile radio network with a mobile radio terminal and a base station;

FIG. 2 time curve when sending voice and signaling data using a voice activity threshold function;

Figure 3 Time course when sending voice and signaling data using a threshold value initial function.

FIG. 1 shows a mobile radio device 10 for coupling to a base station 20, which is connected to a mobile radio network 30. The mobile telephone 10 contains a control device 12 for control and signal processing, which is connected to a transmitting and receiving device 14 and an antenna 15 for transmitting and receiving radio signals. Furthermore, a microphone 16 for recording voice signals and a loudspeaker 18 for transmitting acoustic data are connected to the control device. Both the analysis of the voice data recorded by the microphone 16 and the evaluation of the signals received via the antenna 15 and the transceiver 14 take place within the control device. For example, voice data blocks 40 (shown hatched) and signaling data blocks 42 (dotted) are sent from the mobile phone 10 to the base station 20. The signals received via an antenna 22 of the base station are then forwarded to the connection network 30 for further evaluation. Voice data 44 or signaling data 46 intended for the mobile phone are sent to the mobile phone 10 via the antenna 22 of the base station 20.

FIG. 2 shows a time sequence when a block of voice data 110 and a block of signaling data 120 are sent. In a mobile radio system, the block of voice data can consist, for example, of successive time frames, each of which comprises related voice data. Each of the voice data time frames can in turn consist of several time slots, not all time slots having to contain information. In particular in the case of so-called time domain multiple user systems (TDMA: Time Domain Multiple Access), generally at most one or a few time slots will actually include voice data. The other time slots are then used by other mobile radio devices or a base station or remain free. In a code multiple user method (CDMA: Code Domain Multiple Access) or CDMA multiple use method, for example, all time slots of a frame can include voice data. In general, not only voice data, but also accompanying information (e.g. on channel estimation, power control, format definition, etc.) is transmitted within a voice data time slot.

The voice data block 110 begins at a time to and ends at a time tj. Furthermore, a signaling data block 120 is provided at a time t. A voice activity value 130 is also assigned to the voice data, which indicates how high an "information density" of the voice data is. Such a speech activity value can be generated, for example, by a digital speech analyzer (e.g. a so-called "speech codec"). High speech activity values indicate a high information density and low speech activity values indicate a low information density of the speech data.

Furthermore, when signaling data 120 occurs, a time period dT is started at time t, which is also shown in FIG

Figure 2 is shown. A voice activity threshold function 140 is assigned to this time period dT. After expiration of the time period dT, the signaling data 120 are sent immediately if they have not yet been sent within the time period dT. The increasing voice activity threshold value function 140 with initially very low threshold values and then increasing threshold values towards the end means that at the beginning of the time period dT the signaling data 120 are only sent when the voice activity values 130 are very low, while towards the end of the time period dT the signaling data 120 is already sent with higher voice activity values, ie higher voice information content are sent. In the example shown in FIG. 2, the signaling data 120 is sent at a time t ₂ , at which the voice activity values 130 are below the assigned values of the voice activity threshold function 140 for the first time.

As can be seen in the present example, the signaling data 120 are transmitted here at a time t ₂ at which the speech data 110 contains only relatively little information. This has the effect that the speech data 110 is only minimally disturbed and the sending of the signaling data does not offer any appreciable impairments for a receiver. If, for example, the sending of the signaling data 120 in the present example waited until the time period dT had elapsed, the sending of the signaling data would fall in an area of the speech data block 110 which has a high information content and which leads to a significantly greater disturbance of the transmitted speech data would lead.

FIG. 3 shows a further example in the transmission of voice data 110 and signaling data 120. In this case, a threshold value start function 150 is specified, from which a voice activity threshold value function 152 is obtained. The sending of the signaling data 120 is in turn triggered as soon as the voice activity values 130 of the Speech data 110 lie below the values of the assigned speech activity threshold function 152.

The speech activity threshold value function 152 is obtained from the threshold value start function 150 by subtracting a value associated with the drop in time from the threshold value start function 150 in the case of falling speech activity values, while a value obtained from the increase is subtracted from the threshold value start function in the case of time-increasing speech activity values is added. It can be seen in FIG. 3 that in the case of an unchanged threshold value initial function, the signaling data would have been sent at a time t ₃ . By adapting the speech activity threshold value function 152 to the temporal course of the speech activity values 130, the time for sending the signaling data 120 t is shifted compared to t ₃ at later times, to which speech data 110 with a lower information content belong. By adapting the speech activity threshold value function 152 shown in FIG. 3 to the temporal course of the speech activity values 130, the

Transmission time X.?. for sending the signaling data 120 can be further optimized and thus the quality of the transmitted voice data 110 can be further improved.

An alternative way of achieving a comparable effect as an adaptation of the speech activity threshold function 152 is, for example, to adapt the speech activity values 130 instead of the threshold value start function 150. For example, a speech activity comparison function can be formed from the speech activity values 130. This would then be compared, for example, with the threshold value function 150 or the speech activity threshold function 140. With increasing speech activity values 130 one would choose a corresponding value of the speech activity comparison function smaller than the assigned speech activity value (130), however, with falling speech activity values (130) larger. One way of achieving the behavior described above is to calculate the speech activity comparison function as averaging the speech activity values over a pair of values in the past, for example a moving average of the last, for example three, values. With increasing speech activity values 130, this averaging leads to the fact that the speech activity comparison function is smaller than a current speech activity value and vice versa. A corresponding modification of the speech activity values can, for example, be integrated directly in the algorithm that calculates the speech activity values (in the so-called vocoder or speech codec).

Comment on the speech activity threshold value functions 140, 152, the threshold value start function 150 and the speech activity values 130 in FIGS. 2 and 3: The named functions and values are shown in FIGS. 2 and 3 over the entire period dT for reasons of clarity. Alternatively, however, it can also be provided that after the block of the second data has been sent, no more voice activity values 130 are assigned. Furthermore, it can also be provided that the voice activity threshold value functions 140, 152 and the threshold value start function 150 are not continued after the time t ₂ .

The present invention describes a method for transmitting high-priority first data and lower-priority second data, wherein in a telecommunications device a data block from second data to one

Time t is provided for sending and at this time t first data is already being sent by the telecommunication device or is provided for sending, a time course of important values being assigned to a time course of first data and a time t ₂ for sending the data block of the second data using at least one of the Importance values is determined. By assigning a time profile of importance values to the time profile of the first data, the present method enables an improved determination of a transmission time t ₂ for sending a data block of lower priority data.

An improvement in the quality in the transmission of high-priority first data can be achieved without appreciable impairment in the transmission of lower-priority second data.
