detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the invention discloses a network access method and a terminal, which can speed up the network search of the terminal, thereby improving the user communication experience of the terminal.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a network access method according to an embodiment of the present invention; wherein the method shown in FIG. 1 can be applied to a smart phone (such as an Android mobile phone, an iOS mobile phone, etc.), a tablet computer, In a terminal such as a wearable device. As shown in FIG. 1, the network access method may include the following steps:

S101. Search for frequency information of a neighboring cell of the current frequency point when detecting that the terminal is in a no-service state.

For example, if a mobile phone registers with the upper frequency to register the network, but suddenly enters the no-service state due to various reasons (such as weak signal, entering the tunnel, etc.), then when the mobile phone is in an unserviced state, It will periodically scan the frequency information of the neighboring area of the current frequency point.

Among them, it should be pointed out that different operators will have different frequency bands, and each frequency band will contain many frequency points. For example, for the GSM900 system (operating frequency band 890-960MHz), the frequency interval Both are 200KHz. In this way, according to the frequency interval of 200KHz, it is divided into 125 radio frequency segments from 890MHz, 890.2MHz, 890.4MHz, 890.6MHz, 890.8MHz, 891MHz...915MHz, and each frequency band is numbered, from 1, 2, 3, 4... 125; These numbers for fixed frequencies are what we call frequency points; on the other hand, the frequency points are numbers for fixed frequencies. In the GSM network, we use the frequency instead of the frequency to specify the transmit frequency of the transceiver unit. For example, the frequency of a given carrier is 3, which means that the carrier will receive an upstream signal with a frequency of 890.4 MHz and transmit the signal at a frequency of 935.4 MHz. Among them, the frequency band of GSM900 can be divided into 125 frequency points (the actual available 124). Among them, 1 to 95 belong to China Mobile and 96 to 124 belong to China Unicom.

It is to be noted that, before the searching for the frequency information of the neighboring cell of the current frequency point, the method further includes: determining the number of neighboring cells of the cell where the current frequency point is located; and when the number of the neighboring cells is greater than When the preset number is used, the priority of the neighboring area is determined according to the distance and the azimuth; the cell whose priority is greater than the preset number of stages is determined as the target cell; and the frequency information of the neighboring area of the current frequency point is searched, including: searching Frequency point information of the target cell.

Among them, it should be pointed out that the cell is the smallest regional unit in the mobility management, and the coverage of the communication network signal is divided into many small and small areas through the coverage of the antenna, and several users are connected to each area. And communicate. For example, there is a base station (communication tower) whose effective coverage distance (the mobile phone can receive the signal and also can send the signal to the base station) is 10KM, then draw a circle with the base station as the center and 10km as the radius. This circle is the "cell" formed by the coverage of this base station.

For example, if the number of neighboring cells in the cell where the current frequency is located is three, and the preset number is one, the terminal determines the priority of the neighboring cell according to the distance between the terminal and the neighboring base station. For example, the closer the distance is, the higher the priority is, so the neighbor with higher priority is selected as the target neighbor.

Further, if the number of the neighboring cells whose priority is greater than the preset number of times is N, and N is greater than 2, the determining that the cell with the priority greater than the preset number of cells is the target cell includes:

Obtaining a size of data to be transmitted of the N neighboring cells and/or a data transmission rate of the N neighboring cells;

The neighboring cell whose data to be transmitted is smaller than the first threshold and/or the data transmission rate is greater than or equal to the second threshold is used as the target cell.

The first threshold and the second threshold may be customized by the terminal, or may be user-defined, and are not limited herein.

For example, if N=3, the three neighboring areas are: neighboring area 1, neighboring area 2, and neighboring area 3. The size of the data to be transmitted in the neighboring area 1 is A, and the data transmission rate of the neighboring area 1 is V1. The data transmission rate of the area 2 is B, the data transmission rate of the neighboring area 2 is V2, the size of the data to be transmitted in the adjacent area 3 is C, and the data transmission rate of the adjacent area 3 is V3, A>B>C, V1>V2 >V3, if A in A, B, and C is less than the first threshold, and V1 in V1, V2, and V3 is greater than the second threshold, then neighboring cell 1 is used as the target cell.

Obtaining the number of terminals carried by the N neighboring cells;

The neighboring cell with the smallest number of bearers is used as the target cell.

For example, if N=3, the three neighboring areas are: neighboring area 1, neighboring area 2, and neighboring area 3. The number of terminals carried in the neighboring area 1 is 100, and the number of terminals carried in the neighboring area 2 is 120. The number of terminals carried in the neighboring area 3 is 150, and the neighboring area 1 is taken as the target cell.

Obtaining Reference Signal Received Quality (RSRQ) of the N neighboring cells;

The neighboring area with the largest RSRQ is taken as the target cell.

The specific implementation manner of the terminal acquiring the RSRQ: the terminal obtains a Reference Signal Received Power (RSRP) and a Received Signal Strength Indicator (RSSI) from a network device (such as a base station) in the neighboring cell; RSRP and RSSI determine the RSRQ.

The specific implementation manner of determining RSRQ according to RSRP and RSSI is: RSRQ is M times the ratio of RSRP to RSSI, and the calculation formula is RSRQ=M*RSRP/RSSI, where M represents the number of resource blocks included in the measurement bandwidth of the RSSI. Can reflect the relative size between signal and interference.

For example, assuming N=3, the three neighboring areas are: neighboring area 1, neighboring area 2, and neighboring area 3. The RSRQ of the neighboring area 1 is a, the RSRQ of the neighboring area 2 is b, and the RSRQ of the neighboring area 3 is c, a>b>c, then The neighboring area 1 serves as a target cell.

In addition, when searching for the frequency of the target neighboring area, it is necessary to determine the remaining frequency point of the target cell; and perform a frequency point search from the remaining frequency points.

S102. Select a preset number of frequency point information from the frequency point information of the searched neighboring area for storage.

The preset number may be the default of the system, or may be set by the user. Usually, the number of presets is multiple, such as three, five, etc., and no limitation is imposed here.

For example, the selected frequency point information may be stored in the neighboring cell list, or may be stored in a database or other storage unit, and is not limited herein.

S103. When detecting that the terminal re-connects the network, searching for the stored frequency point information to perform network registration.

It should be noted that the stored frequency point information is information of a standard network supported by the terminal. For example, if the terminal supports China Mobile or China Unicom, then it is necessary to search for China Mobile's network frequency.

Optionally, if the registration network is successful, the frequency of registration success is added to the historical registration list.

Specifically, after the searching for the stored frequency point information to perform network registration, the method further includes: acquiring a current geographic location of the terminal if the registration network is successful; establishing the geographic location and the frequency point Mapping relationship; storing the mapping relationship between the geographic location and the frequency point.

It should be noted that the subsequent terminal may determine a frequency point corresponding to the current location information according to the current location information and the mapping relationship, and access the network through the frequency point.

For example, the terminal can be connected to Wi-Fi (Wireless Fidelity) to obtain current location information through Wi-Fi, but the terminal does not insert a SIM card (Subscriber Identification Module) when the terminal is inserted into the SIM. When the card is used, the frequency information corresponding to the current location information can be determined by the location information acquired by the Wi-Fi and the mapping relationship, and then the network can be accessed through the frequency point.

In addition, it is to be noted that after the searching for the stored frequency point information for network registration, the method further includes: if the registration network fails, performing full frequency scanning; performing network registration according to the scanned frequency point.

As can be seen from the above, in the embodiment of the present invention, when detecting that the terminal is in the no-service state, searching for the frequency point information of the neighboring area of the current frequency point; and selecting a preset number from the frequency information of the searched neighboring area. Frequency The information is stored; when it is detected that the terminal re-connects the network, the stored frequency point information is searched for network registration. It can be seen from the above that by using the technical solution provided by the present invention, the speed of the terminal search network can be accelerated, thereby improving the user communication experience of the terminal.

S201. When detecting that the terminal is in a no-service state, determine the number of neighboring cells of the cell where the current frequency point is located.

For example, if a mobile phone is registered to the network by registering the upper frequency point, but suddenly enters the no-service state due to various reasons (such as weak signal, entering the tunnel, etc.), then when the mobile phone is in an unserviced state, It will periodically scan the frequency information of the neighboring area of the current frequency point.

In the case of a cell, the base station uses different electromagnetic waves to cover different areas, that is, is divided into different cells, and usually one base station is divided into three cells.

For example, if the number of neighboring cells in the cell where the current frequency is located is three, and the preset number is two, the terminal determines the priority of the neighboring cell according to the distance between the terminal and the neighboring base station. For example, the closer the distance is, the higher the priority is, then the two neighboring areas with higher priority are selected as the target neighboring area.

S202. When the number of neighboring cells is greater than a preset number, determining a priority of the neighboring cell according to a distance from the neighboring cell.

S203. Determine a cell whose priority is greater than a preset number of stages as a target cell.

For example, three neighboring areas are divided into three priorities. If you choose two of them, then the priority level is selected to be greater than or equal to the second level, with the highest level.

S204. Search for frequency point information of the target cell.

The searching for the frequency point information of the target cell includes: determining a residual frequency point of the target cell; and performing a frequency point search from the remaining frequency points.

It should be noted that the stored frequency point information is information of a standard network supported by the terminal. Than If the terminal supports China Mobile or China Unicom, then it is necessary to search for China Mobile's network frequency.

S205. Select a preset number of frequency point information from the searched frequency information of the neighboring area for storage.

S206. When detecting that the terminal re-connects the network, searching for the stored frequency point information to perform network registration.

S208. Store a mapping relationship between the geographic location and the frequency point.
