Abstract

The invention discloses a bimodal GSM physical layer system and a realizing method thereof. The method comprises the following steps: a GSM physical layer realizes the deviation of frame timing between two asynchronous GSM and TD-SCDMA systems by controlling a time processing unit in the GSM and a time processing unit in the TD-SCDMA; under the mode mainly based on GSM, GSM controls the TD-SCDMA system to independently arrange the time for processing tasks; under the mode that GSM is dependent, the TD-SCDMA system notifies GSM of the idle time by functions. By adopting the mutual measurement,the time synchronization and the message interaction which are realized between bimodal time-asynchronous systems, the bimodal GSM physical layer system and the realizing method of a bimodal basebandchip provides convenience to the coexistence and independent and normal work of two time-asynchronous systems .Thus, the GSM / TD-SCDMA bimodal mechanism is realized.

Description

technical field [0001] The present invention belongs to a mobile communication system and its implementation method, and in particular relates to a hand-held terminal and a bottom-level implementation method and system of digital baseband chips, which are mainly applied to the GSM side physics of the digital baseband of the GSM / TD-SCDMA dual-mode system. In the mechanism of how the layer implements the dual mode. Background technique: [0002] In the prior art, GSM is currently the most popular second-generation mobile communication system; and TD-SCDMA is a third-generation mobile communication system independently proposed by China. In order to facilitate the user's choice, the terminal of the existing technology needs to support GSM technology and TD-SCDMA technology at the same time, and can perform purposeful mobile roaming or handover in the GSM network or TD-SCDMA network. This is the dual-mode technology . [0003] At present, the main dual-mode application of GSM / ...
