  • Other applications for such measurements are, for example, position determination or paging functions. In principle, measurements are of course also possible within your own existing connection.
  • the setting or reconfiguration of a service must also be carried out for a large number of closely adjacent subscriber stations, for example within a radio cell, in order to reduce the interference caused.
  • reconfiguration signaling is sent from the base station to the corresponding subscriber stations.
  • Known approaches according to the prior art are based on the fact that the base station sends a corresponding measurement job to the subscriber station (s) and thereby pauses or correspondingly configures the existing service.
  • This configuration consists, for example, of time, code, frequency, modulation, transmission line, puncturing, etc.

  • These adjacent radio systems can be, for example, radio cells or base stations of a UMTS mobile radio system that supports the TDD mode or of the known GSM mobile radio system.
  • the transmission device can also be generated to generate transmission gaps.
  • the generation of transmission gaps in the inherently continuous data stream takes place using the so-called compressed mode. Data to be sent in the transmission gap is actually transmitted at a higher data rate before and after the transmission gap.

  • a handover is initiated from the first base station NB1 to the second base station NB2.
  • the transmission in the FDD mode of the first radio communication system takes place continuously, a physical transmission channel being defined by a frequency and a connection-specific spreading code (CDMA code).

  • the monitoring of GSM and TDD from UMTS FDD mode turns out to be the most important application. Since there is no synchronicity between two different systems, it is difficult for the base stations to specify a time for the measurement. However, some systems (eg FDD, TDD, TD-SCDMA) have the same frame length or a corresponding multiple, which keeps the time of measurement sufficiently constant for a long time in relation to a time system. Thus, after the first measurement of the other system or a complete time frame of the other radio system, by means of which a position of the object to be measured (for example radio channel) is known, the subscriber station can specify a minimum transmission gap by requesting a desired start and length of the measurement.
