Abstract

The invention discloses a method and device for entering a dual transfer mode to request radio resources, which are applied to a mobile terminal with a radio resource control (RRC) entity. According to the invention, an RRC entity of an MES (Mobile Earth Station) is deleted so as to initiate a management protocol of requesting radio resources through entering a DTM (Dual Transfer Mode), definitions of signalling GSS (Gateway Station Subsystem) Iu mode DTM REQUEST and GSS Iu mode DTM REJECT of t RRC are deflected at the same time, and a first MAC (Media Access Control) entity of the MES is responsible for management control for entering the DTM to request radio resources, thereby realizing conversion from double-layer entity control management to single-layer entity control management, simplifying the process of entering the DTM to request radio resources, and improving the transmission efficiency of data in a satellite mobile communication system.

Description

technical field [0001] The invention relates to the field of satellite mobile communication, in particular to a method and device for entering a dual transmission mode and requesting wireless resources. Background technique [0002] At present, the GEO-Mobile Radiointerface (GMR) standard was originally developed to formulate the GEO satellite mobile communication system air interface technical specification based on the Global System for Mobile Communication (GSM) standard. , Divided into GMR-1 and GMR-2, among them, the GMR-1 standard is applied to the Thuraya system in the Middle East. With the evolution of the terrestrial cellular GSM to 3G standard, the GMR-1 standard has also evolved, and has passed through the stages of GMR-1Release1, GMR-1Release2 (ie GMPRS) and GMR-1Release3 (ie GMR-1 3G). Dual Transfer Mode (DTM for short) is a key technology applied in the GMR-1 3G satellite communication system, which can support the voice service (CS) and data service (PS) conc...
