Method for performing communication service by using plurality of modems

說明書
502: The second modem MODEM 2 performs a data service in a high frequency band, that is, occupies a radio frequency device, namely, a service resource, corresponding to the high frequency band. The MODEM 1 and the MODEM 2 are in a DSDA mode. For example, before the MODEM 2 performs the data service in the high frequency band, the MODEM 2 receives a data service request. For example, the MODEM 2 generates the data service request in response to an operation of the user, or the MODEM 2 receives the data service request sent by a software program or the like. Then, the MODEM 2 sends a data service resource request to the arbitration apparatus based on the data service request, where the data service resource request carries information about the high frequency band. The arbitration apparatus determines, based on the information about the high frequency band and according to the preset correspondence table, that the information about the high frequency band does not conflict with information about a frequency band corresponding to another communication service on the terminal. In this case, the arbitration apparatus returns a second acknowledgment response to the MODEM 2. The MODEM 2 establishes the data service based on the second acknowledgment response.
