摘要：
A method for initial synchronization with TD-SCDMA system in the connection mode of GSM system, to resolve the problem of the downlink synchronization codes (DwPTS) may be undetectable or taking too much time to be detected when a TD-SCDMA/GSM dual-mode terminal is examining TD-SCDMA frames in GSM connection mode with prior art; in the connection mode of the GSM system, the method receives or transmits service data within the service time slots of the GSM frame at the radio frequency band of the GSM system, and receives TD-SCDMA signal within the idle time slots of the GSM frame at the radio frequency band of the TD-SCDMA system, and detects DwPTS in the received TD-SCDMA signal, thus the terminal in the connection mode of the GSM system can quickly detect the DwPTS in TD-SCDMA frames, achieving the initial synchronization of the TD-SCDMA/GSM dual-mode system. A GSM system processing apparatus and a communication apparatus are also disclosed in the invention.
