The invention discloses a dual-
mode switching method for a mobile terminal, an adapting device and the mobile terminal. The method comprises the following steps of: after receiving a switching command of a first
radio resource control (RRC) module, forwarding the switching command to a mobile management (MM) module and a second RRC module; and finishing message interaction among the first RRC module, the MM module and the second RRC module to realize
mode switching of the MM module and the second RRC module. The first RRC module is a GRRC module, and the second RRC module is a URRC module. Or the first RRC module is a URRC module, and the second RRC module is a GRRC module. The dual-
mode switching method for the mobile terminal, the adapting device and the mobile terminal provided by the invention provide encapsulation of interfaces for message transfer between different
modes, realize unification of management, and are convenient for later maintenance.
