Problems solved by technology

[0003] When a terminal performs redirection between a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system and a Long Term Evolution (LTE) system, due to inter-system threshold settings and target network system Due to different reasons such as the coverage under the network, the congestion of the target network, etc., the terminal failed to redirect on the target network, and then returned to the original system for redirection, which caused the terminal to frequently redirect between the current network and the target network in a short period of time. It affects the user's perception, increases the signaling overhead, and increases the burden on the device

Embodiment Construction

[0037] Embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0038] The redirection of the terminal in LTE is to redirect to the cell corresponding to the frequency point information according to the frequency point information of the cell to which the terminal is redirected carried in the RRC connection release message. Redirection is classified into RRC rejection-based redirection, RRC release-based redirection and measurement-based redirection. In the prior art, for a terminal redirected from a TD-SCDMA system to an LTE system, only the redirection indication information in the RRC request message sent by the base station to the terminal is considered to be redirected, if the redirection indication information indicates that the terminal is not allowed to redirect , the terminal always refuses redirection. Although this method prevents frequent redirection of the terminal between different systems, in some ...

Abstract

The invention provides a method for preventing ping-pong redirection of a terminal and a base station. The base station receives a redirection request message from a terminal, and then whether a timeraimed at the terminal is started and overtime occurs is determined, and the timer is used to timing a redirection rejecting period; if the timer is started and overtime does not occur, whether the terminal is allowed to carry out redirection within the timing period of the timer of the terminal is determined according to a redirection reason of the terminal; and if NO, the redirection request message is rejected. Thus, the terminal is prevented from repeated redirection within the set period.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for preventing terminal ping-pong redirection and a base station. Background technique [0002] Commonly used redirection is divided into redirection based on radio resource control (Radio Resource Control, RRC) rejection, redirection based on RRC release, and measurement-based redirection. Redirection based on RRC release means that by carrying the frequency point and other access information of the target cell in the Radio Resource Control (RRC) signaling release, the terminal disconnects from the cell and accesses the The purpose of the process of the target cell is to enable the terminal to continue to receive services by redirecting access to the target cell. [0003] When a terminal performs redirection between a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system and a Long Term Evolution (LTE) system, due to inter-system threshold se...
