Method for switching high-standard network, terminal, and server

Abstract

The invention discloses a method for switching a high-standard network, comprising the following steps: sending a high-standard network query request to a server when determining that a terminal does not reside in a highest-standard network supported by the terminal currently; and when determining that there is a network of which the standard is higher than the current network standard according to an acquired query result, switching the current network to a highest-standard network of which the standard is higher than the current network standard and which can be supported by the terminal. The invention further discloses a terminal and a server.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for switching high standard networks, a terminal and a server. Background technique [0002] With the development of wireless communication technology, the mobile communication network has been represented by the second generation mobile communication network (2G, Second Generation) system represented by Global System for Mobile Communication (GSM, Global System for Mobile Communication) and General Packet Radio Service (GPRS, General Packet Radio Service). And the third-generation mobile communication network (3G, 3rd-Generation) system represented by Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) technology, Time Division Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) technology, etc., It has developed to the fourth-generation long-term evolutio...

In the prior art, when there is no LTE network coverage, the terminal will automatically register to the 3G network or 2G network. If the terminal moves to a place with 4G network coverage, it will Automatic re-measurement resides in the 4G network, but in the case of current data services, it can only be achieved by the network side when the network signal quality of the current standard drops to a certain threshold, which is not enough to maintain the interaction between the terminal and the network Initiate network search and switch, and re-reside on the new network; for mobile terminals, it is not uncommon for the terminal to have data services and move. Once the 4G network signal is lost, after residing in the 3G / 2G network, Returning to a place where there is 4G network coverage, but the signal quality of 2G / 3G network still meets the requirements, it will also stay on the 2G / 3G network for a long time, which will affect the user experience and violate the end user's purchase of 4G equipment to enjoy high-speed Internet access and better quality. The original intention of the network service
