Abstract:
A management method and apparatus for supporting multiple SIM cards to share an RF processor. The method includes: after receiving a resource request sent by a first baseband communications processor, determining whether the RF processor is authorized be used by a second baseband communications processor in at least a part of a time period required for using the RF processor by the first baseband communications processor; if yes, comparing whether a priority of a type of a first communications service that needs to be performed by the first baseband communications processor is higher than a priority of a type of a second communications service performed by the second baseband communications processor; and if yes, sending an authorization message to the first baseband communications processor and instructing the second baseband communications processor to stop performing the second communications service.
