Problems solved by technology

[0005] The present invention provides a network switching method, a terminal and a server, which are used to solve the problem that in the prior art, when the terminal is at different LTE frequency points when calling and hanging up, the terminal cannot directly switch back to the LTE network and needs to re-select the idle state of the terminal. Cells are used to switch LTE networks, which increases the technical problem of network switching delays for terminals

Abstract

The invention discloses a network switching method, a terminal and a server. The method comprises the steps that: the terminal detects the change condition of the position where the terminal is located in a process of carrying out voice communication in a circuit domain fallback mode from an LTE network; when the position change of the terminal exceeds a set threshold, current position information is sent to a network side server; and after terminating the voice communication, the terminal switches back to the LTE network according to a communication frequency point corresponding to the current position information and returned by the server. When switching back from the circuit domain network to the LTE network, the terminal directly accesses the LTE network by using the communication frequency point corresponding to the current position information, thereby avoiding the situation that when a communication cell of the terminal changes, the terminal cannot directly switch back to the LTE network but needs to re-select a cell in an idle state of the terminal to realize the switch, and accelerating the network switching speed of the terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a network switching method, a terminal and a server. Background technique [0002] Now, the Long Term Evolution (LTE) network of general mobile communication technology is in the initial stage of development, and the network coverage cannot reach full coverage. Therefore, Circuit Switched Fallback (abbreviation: CSFB) is usually adopted to solve the voice call problem of the terminal . Specifically, the terminal needs to fall back to the circuit domain network to process the CS service, and needs to switch back to the original LTE network after the CS service is processed. [0003] At present, one of the methods for a terminal to switch from a circuit domain network to an LTE network is a terminal autonomous fast switching method, and the terminal needs to support an autonomous switching function on the chip. The terminal autonomous switching method is that the t...
