Processing method and device for abnormal card no-loading in LTE network

Abstract

The invention discloses a processing method and a processing device for abnormal card no-loading in an LTE network. The processing method comprises the steps of: analyzing a received registration rejection message and / or tracking area update rejection message to determine whether a rejection reason is a predetermined rejection reason; and under the condition that the rejection reason is the predetermined rejection reason, resetting a network mode to cancel long term evolution LTE network support, or, adding a current tracking area TA into a forbidden TA list and re-launching a 2G / 3G network searching process. The processing method selects an appropriate manner to re-launch the 2G / 3G network searching process according to a reason type corresponding to the rejection message, can avoid the network off-line and card no-loading phenomena caused by registering to the LTE network continuously, and solves the problem that the user experience is severely affected since conditions such as unavailable PS and repeated network off-line occur at a terminal side when a user registers to the LTE network according to situations prescribed by a protocol.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for processing abnormal card loss in a Long Term Evolution (LTE) network. Background technique [0002] 3G users on an operator's existing network sometimes experience network and card dropouts when using LTE terminals, and they can only be restored by restarting the terminal, which seriously affects user experience. [0003] Further analysis found that this is because most of the operator's 3G users have already used the Universal Subscriber Identity Module (USIM) card, and the theoretical USIM card itself can support LTE; when these users use LTE terminals, they may use LTE. The network initiates the registration, but it will be rejected under the current LTE network (may be caused by the operator's policy), and some reasons for rejection will cause the card to be invalid according to the protocol specification, packet switching (PacketSwitch, referred ...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a processing method and device for abnormal card loss under the LTE network, which is used to solve the problem that in the prior art, when registering the LTE network according to the conditions stipulated in the agreement, the PS is unavailable on the terminal side, or the network is repeatedly dropped, etc. Circumstances that seriously affect the user experience
