Embodiment Construction

[0045] In the existing SGSN dismantling process in the Pool, when the BSC or RNC reassigns the SGSN to the mobile users attached to the SGSN with a heavy load, it uses the polling method. In this way, there is no Targeted, and the migration efficiency is low. In view of the above problems, the embodiments of the present invention provide a method, device and system for migrating user terminals in a pool. The BSC or RNC can directly migrate the user terminals to the target SGSN only according to the received NRI and non-broadcast RAI of the target SGSN. SGSN, so as to realize the directional migration in the Pool.

[0046] Before executing the method provided by the embodiment of the present invention, load information such as respective loads and operating conditions reported periodically by each SGSN in the Pool are stored on the OMC, so that the OMC can monitor the load conditions of all SGSNs in the Pool in real time. If some SGSNs are overloaded, one or more target SGSNs ...

Abstract

The embodiment of the invention provides a method, a device and a system for user terminal transfer in a pool. The method comprises the following steps: a BSC (Basic Station Controller) or an RNC (Radio Network Controller) receives a transfer request sent by a user terminal; and the user terminal is transferred from a source SGSN (Serving GPRS Support Node) to a target SGSN according to an NRI (Network Resource Identity) and a non-broadcast RAI (Routing Area Identity), carried in the received transfer request, of the target SGSN. According to the embodiment of the invention, the load of an SGSN in a pool does not need to be adjusted by the BSC or the RNC, the BSC or the RNC can transfer the user terminal from a source SGSN to a specified target SGSN only according to the NRI, carried in the transfer request sent by the user terminal, of the target SGSN, directional migration is realized, and the migration efficiency is high.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, device and system for migrating user terminals within a pool. Background technique [0002] At present, the Serving GPRS Support Node (SGSN) pool (Pool) is a new networking mode, which breaks the traditional network in a base station controller (Basic Station Controller, BSC ) / Radio Network Controller (Radio Network Controller, RNC) can only be connected to the restriction of one SGSN. [0003] Specifically, such as figure 1 As shown, a Pool area can include a group of SGSNs running in parallel (such as SGSN101, SGSN102 and SGSN103), and this group of SGSNs can be routed to multiple BSC / RNCs (such as BSC / RNC104, BSC / RNC105, BSC / RNC106 and BSC / RNC107), sharing services in the Pool area. Here, each BSC / RNC has the function of selecting an SGSN to provide services for a mobile subscriber (Mobile Subscribdr, MS). In this way, when the MS (or a user ...
