Dual-network mobile terminal

Abstract

The invention discloses a dual-network mobile terminal. The dual-network mobile terminal comprises a base station power detection module, a power control module and a communication module, wherein the base station power detection module, the power control module and the communication module are sequentially connected through circuits. By means of the dual-network mobile terminal, the problem that networks are frequently reselected and switched when the mobile terminal is located at the edge of a community is solved, communication can be prevented from being terminated when the mobile terminal is switched between the TD-CDMA network and the GSM network, and the call drop problem can be prevented.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a dual-network mobile terminal which can operate in a TD-CDMA network and a GSM network system. Background technique [0002] The current communication network is composed of cross coverage of different communication networks. When a mobile terminal moves from one communication cell to another, it will detect the network covered by the cell, and then perform cell reselection and cell handover. [0003] The current handover strategy for mobile terminals in the communication network is to make TD-CDMA users, especially data services, use TD-CDMA network resources as much as possible while taking user experience into consideration. That is, first use the TD-CDMA network resources of the current cell for signal transmission; if the TD-CDMA network resources of the current cell do not meet the communication requirements, check whether the TD-CDMA network of the adjacent cell ca...

Problems solved by technology

[0004] At the same time, there are still several problems in the operation of switching between the TD-CDMA network and the GSM network: On the one hand, the communication of the mobile terminal is temporarily terminated during the process of switching between the TD-CDMA network and the GSM network. Failure to be called successfully will cause inconvenience to the mobile terminal user; on the other hand, if the mobile terminal switches between the TD-CDMA network and the GSM network for too long, it is likely to cause a call drop problem, which will cause a problem to the main party who is talking. Inconvenience to the called party; Third, frequent network reselection and switching at the edge of a larger TD-CDMA network cell is not conducive to maintaining the continuity of terminal services, but also increases the network interoperability. Signaling interaction increases the network signaling load
