1. A management method for supporting a plurality of SIM cards to share an RF processor is applied to a mobile terminal, and is characterized in that the method comprises the following steps:

  • receiving a resource request sent by a first baseband communication processor, wherein the first baseband communication processor is used for realizing a first communication service of a first SIM card, the resource request is used for requesting the use right of an RF processor for the first communication service, and the resource request comprises the type of the first communication service and a start-stop time period needing to use the RF processor;

    the resource request is sent by a physical layer of the first baseband communication processor, or the resource request is sent by a radio resource control, RRC, layer of the first baseband communication processor;

    determining whether the RF processor is authorized to execute a second communication service of a second SIM card for a second baseband communication processor in at least part of the time period within the starting and stopping time period;

    comparing whether the priority of the type of the first communication service is greater than the priority of the type of the second communication service when the RF processor is authorized to execute the second communication service for the second baseband communication processor in at least part of the starting and ending time period, wherein the priority of the type of the first communication service and the priority of the type of the second communication service are determined according to a standard quality of service class identifier (QCI) attribute;

    when the priority of the type of the first communication service is higher than the priority of the type of the second communication service, sending a first authorization message to the first baseband communication processor and coupling the first baseband communication processor with the RF processor, and informing the second baseband communication processor to stop executing the second communication service, wherein the first authorization message is used for authorizing the first baseband communication processor to execute the first communication service by using the RF processor;

    the comparing whether the priority of the type of the first communication service is greater than the priority of the type of the second communication service includes;

    judging whether the second communication service can be seized or not;

    when the second communication service can be preempted, comparing whether the priority of the type of the first communication service is greater than that of the type of the second communication service;

    the method further comprises the following steps;

    when the priority of the type of the first communication service is less than or equal to the priority of the type of the second communication service, sending a resource request failure message to the first baseband communication processor, the resource request failure message being used for indicating that the first baseband communication processor is not authorized to execute the first communication service by using the RF processor;

    the RF processor provides an RF communication link for the first communication service when the first baseband communication processor is authorized to use the RF processor.
