606: The arbitration apparatus determines whether a low frequency band corresponding to the MODEM 1 conflicts with the high frequency band corresponding to the MODEM 2. The arbitration apparatus determines, according to a preset correspondence table, whether the low frequency band corresponding to the MODEM 1 conflicts with the high frequency band corresponding to the MODEM 2. The preset correspondence table is described in operation 506 shown in
607: If no conflict occurs, the arbitration apparatus maintains the DSDA mode. If the arbitration apparatus determines that the low frequency band corresponding to the MODEM 1 does not conflict with the high frequency band corresponding to the MODEM 2, it indicates that the voice service on the MODEM 1 and the data service on the MODEM 2 can be performed concurrently. Then, the arbitration apparatus maintains the DSDA mode. In this case, the MODEM 1 operates in a low frequency band, and occupies a service resource corresponding to the low frequency band. The MODEM 2 operates in a high frequency band, and occupies a service resource corresponding to the high frequency band.
608: The arbitration apparatus sends a frequency band update acknowledgment message to the MODEM 1. In other words, the MODEM 1 is indicated to operate in a low frequency band.
