Problems solved by technology

[0002] The second-generation mobile communication network GSM / GPRS and CDMA (2G) began to be used in the 1980s. Up to now, the total number of mobile users in the world has reached more than 1 billion. With the continuous increase of users' demand for services, the existing second Modern mobile communication systems have been difficult to meet the requirements of high-speed data
Compared with the third-generation mobile communication system and the second-generation mobile communication system, each standard is quite different in physical hardware and physical hardware control layer, but it has tried to be consistent in the wireless protocol stack standard, and it is also for the system However, the transition from the second-generation GSM / GPRS to the third-generation CDMA2000, WCDMA and TD-SCDMA has great differences in terms of service characteristics, network capacity and design ideas, so it is necessary to support multiple It is still very difficult to integrate the modular terminal at all layers of the protocol stack

Embodiment 1

[0055] The terminal of the present invention is composed of physical hardware and software layers.

[0056] Physical hardware is a physical hardware structure that communicates with multiple mobile communication systems to achieve service in two or more mobile communication networks.

[0057] Physical hardware structure such as figure 2 , including a data processing system 200, a peripheral interface 210, a human-machine interface layer 220 providing a window for users to select access technologies, and a radio frequency transceiver module 230.

[0058] The data processing system may include a baseband processor 201, a MODEM-based chip 202 supporting GSM / TD-SCDMA / WCDMA, a data signal processor (DSP) 203 for completing baseband functions, and a memory for storing software layer data. Receptacle 204.

[0059] The peripheral interface 210 includes various standard peripheral interfaces, such as keyboard, speaker, earphone and other peripheral hardware standard interfaces (not ...

Embodiment 2

[0099] In this embodiment, the hardware of the terminal is the same as that in Embodiment 1. The software layer structure of this embodiment includes a man-machine interface module, an access technology identification table 340, a driver module 330, a routing function module 300, a fusion layer 310 and Unfused layer 320 .

[0100] The difference is that if Figure 5 As shown, the fusion layer 310 includes a non-access layer 412 of the wireless protocol stack layer and a protocol stack adaptation layer 411 , that is, the terminal has only one shared non-access layer 412 and one shared protocol stack adaptation layer 411 .

[0101] The wireless protocol stack layer also includes an access layer 421 . The non-access layer includes a connection management layer and a mobility management layer. The access layer includes the radio resource management layer and the data link layer. The data link layer includes wireless link management layer, media access layer and GSM / GPRS data la...

Embodiment 3

[0121] In this embodiment, the hardware of the terminal is the same as that in Embodiment 1. The software layer structure of this embodiment includes a man-machine interface module, an access technology identification table 340, a driver module 330, a routing function module 300, a fusion layer 310 and Unfused layer 320 .

[0122] The difference is that if Figure 7 As shown, the fusion layer includes the wireless resource management layer 713 of the access layer of the wireless protocol stack layer, the non-access layer 712, and the protocol stack adaptation layer 711, that is, the wireless resource management layer 713, The non-access layer 712 and the protocol stack adaptation layer 711 are integrated, that is to say, the functional modules between the wireless resource management layer 713 of the access layer, the non-access layer 712 and the protocol stack adaptation layer 711 of the system can communicate with each other. switch.

[0123] The wireless protocol stack la...

Abstract

A multimode mobile communication terminal consists of physical hardware including data processing system , peripheral interface , man-machine boundary layer and radio frequency transceiving module ; and software layer including mergence layer ,route function module of unmerged layer and wire-in technique identification table . Its multimode converting method includes writing wire-in technique identification into storage , fetching wire in technique and sending it to route module by merging layer and routing said technique in each unmerged layer, selecting network , finding cell for resident , returning confirmation message back to let terminal reside normally.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a multi-mode mobile communication terminal and a multi-mode communication method thereof. Choose the method of communication between. Background technique [0002] The second-generation mobile communication network GSM / GPRS and CDMA (2G) began to be used in the 1980s. Up to now, the total number of mobile users in the world has reached more than 1 billion. With the continuous increase of users' demand for services, the existing second Modern mobile communication systems have been difficult to meet the requirements of high-speed data. At the same time, mobile communication technology has developed from the existing second generation to the third generation mobile communication system (3G) based on WCDMA, TD-SCDMA and CDMA2000. The third generation mobile communication system meets the quality of service requirements of a large number of data services , and improve the...
