Abstract

The present invention provides a method and system for realizing MM connection of a satellite mobile communication terminal protocol stack. When a satellite mobile communication terminal initiates a service request, the CM sublayer applies to the MM connection management module of the MM sublayer for a service submodule and MM connection management module. The MM connection entity for sub-layer communication. The MM connection entity has an identity tag configured with priority characteristic parameters. The identity tag corresponds to the service ID of the service request one-to-one, and defines three states: idle state, waiting state, and dedicated state and the priority of business requests. In the implementation process of the protocol stack software of the satellite mobile communication terminal, the present invention can make the state machine of the protocol stack proceed in an orderly manner by reasonably managing the MM connection. In the case of delay, some business requests are not responded to for a long time, and the communication connection process is stuck due to the imagination.
