Abstract

A protocol stack module, a baseband chip, a mobile terminal and a network searching method of the mobile terminal are provided. The protocol stack module includes a protocol processing unit includes a communication protocol processing unit and a GPRS protocol processing unit, an information channel which is connected with the communication protocol processing unit and the GPRS protocol processing unit and is used for information interaction between the communication protocol processing unit and the GPRS protocol processing unit, a first baseband control unit and a second baseband control unit which are connected with the communication protocol processing unit and the GPRS protocol processing unit respectively, and a protocol interface which is connected with the protocol processing unit, wherein the protocol interface is used for establishing a communication channel between the protocol processing unit and an interaction module. With the protocol stack module, the baseband chip, the mobile terminal and the network searching method of the mobile terminal provided by the technical scheme of the invention adopted, the problem of incapability of an existing GSM mobile terminal to concurrently process voice communication related service and GPRS data service.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a protocol stack module, a baseband chip, a mobile terminal and a network finding method thereof. Background technique [0002] For GSM mobile terminals, since the GSM network was originally designed for voice services, with the development of data services, the General Packet Radio Service (GPRS) network architecture developed under the GSM network architecture and the original network architecture It is two parallel systems. According to the current network configuration, basically all 2.5G networks operate in network mode 2. The network mode 2 refers to the GSM core network (managed and controlled by the mobile switching center) and the GPRS core network (managed by The Gs interface (the Gs interface of the mobile switching center) is not applied between the VisitorLocation Register (VLR) in the data core network) and the GPRS service node (Serving GPRS Support N...
