摘要

A first modem performs a first communication service in a first frequency band. A second modem performs a second communication service in a second frequency band. The first modem and the second modem are in a first operating mode. The first modem receives, from an access network device, a switching instruction for the first communication service, where the switching instruction is used to instruct the first modem to switch from the first frequency band to a third frequency band. The first modem indicates to an arbitration apparatus that the first modem needs to be switched to the third frequency band. The arbitration apparatus determines whether the third frequency band conflicts with the second frequency band, to perform: maintaining the first operating mode, or switching the first operating mode to a second operating mode for the first modem and the second modem.

說明書

It can be learned from the foregoing process, in a DSDS technology, when the data service of the MODEM 1 is preempted, the data service of the MODEM 1 is interrupted. In addition, when the voice service of the MODEM 1 is preempted, the MODEM 1 cannot receive or answer a call for a mobile terminated service. Consequently, the mobile terminated service is affected. Therefore, although the DSDS technology reduces costs, product performance deteriorates and the service resource is not fully utilized. In addition to a dual SIM application scenario, in other dual-MODEM operating scenarios, how to coordinate the dual MODEMs to improve service resource utilization becomes a problem.

SUMMARY

Embodiments of this application provide a method and an apparatus for performing a communication service by using a plurality of modems, to improve service resource utilization.
