A method for balancing the loads in the mobile communication system and its communication equipment

Abstract

The disclosed loading balance method comprises: the access network node determines the selection of UE CN-node; in the selection range, selects one of current loading parameter, and transmits the UE access signaling. This invention balances loading among all CN nodes efficiently, and improves system stability and reliability.

Description

Technical field [0001] The invention relates to the core network access of a mobile communication system, in particular to a method for realizing load balancing in the core network access of a mobile communication system and a communication device applying the method. Background technique [0002] In an existing mobile communication network, a UE (User Equipment, user equipment) accesses a CN (Core Network, core network) node through an RNC (Radio Network Controller, radio network controller). The CN node that accesses the UE in the circuit domain is usually MSC / VLR (Mobile Switching Center / Visitor Location Register), and the CN node that accesses the UE in the packet domain is usually SGSN (Service GPRS Supporting node). GPRS support node). [0003] When the RNC cannot interpret the UE's IDNNS (Intra Domain NAS Node Selector, Intra Domain NAS Node Selector) value in the initial direct transmission signaling of the Uu interface (the interface between the UE and the radio access n...
