Network registration method, device and mobile terminal

Abstract

Embodiments of the present invention provide a network registration method, device, and mobile terminal. The method includes: when the mobile terminal registers with the network again after receiving the message of refusing to allocate a channel sent by the network, according to the occurrence of network registration failure in the low priority list, The available frequency points are sorted according to the network resource status of the frequency points, and then the camping attempts are made on each available frequency point in turn to determine the camping frequency point, and finally the network registration message is sent to register to the camping frequency point. In this method, the mobile terminal records the information of the corresponding frequency point after receiving the message of refusing to allocate the channel sent by the network. When the mobile terminal re-initiates network registration, it first sorts according to the recorded frequency point information, and ranks the frequency points with poor network resources to low priority, so that the mobile terminal preferentially selects other frequency points with better network resources for registration, improving The success rate of network registration ensures the service reliability of mobile terminals.

Description

technical field [0001] Embodiments of the present invention relate to wireless communication technologies, and in particular, to a network registration method, apparatus, and mobile terminal. Background technique [0002] At present, when a mobile terminal registers with a network, it must go through processes such as scanning frequency points, decoding system broadcast messages and saving, camping, and sending registration messages. The process of sending registration messages includes channel request and registration authentication processes. Since the network resources of the cell are limited, in the process of registering the network, when the load of the cell is overloaded and the network resources are insufficient, the network sends a message to the mobile terminal to reject the allocation of channels, and does not allocate network resources to the mobile terminal, thereby rejecting the access of the mobile terminal. . [0003] In the prior art, after receiving a mess...

[0004] However, during the re-registration process, if the signal of the cell with limited network resources that failed to register before is good, at this time, even if there is a frequency point with sufficient network resources in the network, the mobile terminal will still select the cell with limited network resources for registration.
