Network switching device and method of multimode terminal

Abstract

The invention discloses a network switching device of a multimode terminal. The device comprises an upper application module, a wireless equipment module, a wireless interface module, a signal measurement module, a switch decision module and a message routing control module, wherein the wireless equipment module comprises a wireless honeycomb equipment module and a WIFI (wireless fidelity) equipment module; the signal measurement module is used for measuring the signal indexes of a wireless local area network and a wireless honeycomb network, and sending the index measurement result to the switch decision module; the switch decision module is used for performing switch decision calculation according to the index measurement result, judging whether to switch between the wireless local area network and the wireless honeycomb network, and sending the switch decision result to the message routing control module; and the message routing control module is used for selecting a data channel according to the switch decision result, and controlling to send out a data message through the wireless honeycomb equipment module or the WIFI equipment module.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a network switching device and method for a multi-mode terminal. Background technique [0002] With the evolution of mobile cellular network technology, mobile operators are accelerating the deployment of 3G and even LTE wireless cellular networks. However, due to the environmental protection pressure of residential areas and commercial buildings, it is becoming more and more difficult to select sites to build more wireless cellular base stations in densely populated urban areas. However, due to the small size, low radiation and low power consumption of wireless local area network (Wireless Local Area Networks, wireless local area network) hotspots, they rarely face the problem of site selection similar to wireless cellular base stations. [0003] At present, domestic operators are paying more and more attention to the operation and integration of all services. ...
