Problems solved by technology

[0006] 1. Due to the possible delay caused by multi-mode cell reselection, cell measurement, cell handover, and cell redirection, it will affect the performance related to business continuity
[0007] 2. The 3GPP protocol involved in multi-mode conversion is relatively complex, and the research and development costs are high, and this protocol not only requires the technical upgrade of the terminal-side protocol stack, but also requires the network side to support these protocol functions and upgrade accordingly, thus increasing the complexity of network upgrades complexity of the protocol conformance test, which will increase the cost of the protocol conformance test environment and the cost of the overall protocol stack technology upgrade
[0008] 3. At present, due to the limitations of LTE network coverage, in areas without LTE network coverage, multi-mode single-standby terminals in LTE mode will be in a state of network interruption, so that the continuity of data services cannot be guaranteed

Abstract

The invention provides a method and a device for switching modes of a mobile communication terminal. The mobile communication terminal supports the different communication modes. The method includes initiating network search for a first communication mode when the mobile communication terminal is in a second communication mode; and switching the second communication mode into the first communication mode after a network of the first communication mode is found, and connecting the mobile communication terminal with the network of the first communication mode. The method and the device have the advantage that possible influence of multi-mode cell reselection, cell measurement, cell switching and cell redirection which are specified by 3gpp (the third generation partnership project) international standards on the complexity in interoperation of protocols and the performance related to the business continuity can be prevented.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a mode conversion method and device for a mobile communication terminal. Background technique [0002] With the development of wireless communication technologies, wireless communication networks based on different wireless communication technologies can provide different services for users of mobile communication terminals. When a mobile communication terminal connects to different mobile communication networks, there are different modes, such as GSM / EDGE mode, CDMA mode, WCDMA mode, TD-SCDMA mode, LTE mode, etc., and a terminal with one of the modes is a single-mode terminal . In order to adapt to the network of various standards in the market, multi-mode terminals such as GSM / EDGE / WCDMA dual-mode and GSM / EDGE / TD-SCDMA dual-mode have appeared. [0003] Multi-mode terminals are also divided into different types, such as multi-mode single-standby terminals,...
