Embodiment Construction

[0013] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] The main idea of ​​the present invention is: add a cell reselection notification message between the base station controller (BSC) and the radio network controller (RNC). The message direction is from BSC to RNC. This message is used to bring the identification information of the UE, the identification information of the GSM cell, and the identification information of the target cell to the RNC. After the UE completes the service establishment on the RNC side, it can add a temporary penalty offset to the corresponding GSM neighboring cell when issuing the different system measurement control or processing the different system periodic measurement report, so as to judge the possibility of the UE reselecting to the GSM cell reduce. ...

Abstract

The invention provides a method for preventing user equipment (UE) from crucial cell re-selection between a third generation (3G) network and a second generation (2G) network, which comprises the following steps that: after the UE reselects the 3G network from the 2G network, the difficulty for the UE to reselect to a global system for mobile communication (GSM) cell is increased by increasing the independent bias of an adjacent community of the GSM cell before reselection, so that the crucial cell re-selection of the UE between the 3G network and the 2G network can be effectively prevented.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method for preventing user equipment (UE) from ping-pong reselection between 3G and 2G networks. Background technique [0002] The 3G network has some areas where the 3G network cannot cover, such as coverage holes and coverage edges. In these areas, if the 2G network coverage is good, the user equipment (UE) can be reselected before leaving the 3G coverage area and dropping the call. to the 2G network to avoid dropped calls. However, ping-pong reselection between 3G and 2G networks is easy to occur in the weak coverage area of ​​3G. Taking the reselection between TD-SCDMA and GSM network as an example, when the UE reselects to the After the GSM network, it may reselect to the TD-SCDMA network according to its own parameter configuration. Then reselect again in the GSM due to the signal problem of the TD-SCDMA network, thus enter the ping-pong reselection process between the...
