Local exchange method, core network equipment and network system of implementing in base station controller

Abstract

The invention discloses a method of realizing local exchange in a base station controller, which includes: a core network side judges whether a first user equipment and a second user equipment locate under the same base station controller; if yes, send local exchange message to the base station control; the local exchange message includes: local exchange orders, the first user equipment mark and the second user equipment mark; after receiving the local exchange orders, the base station controller performs local exchange on the data between the first user equipment and the second user equipment. The invention also discloses a corresponding core network equipment and a network system. The technical proposal provided by the invention can reduce user plane data exchange time delay among user equipments under the same base station controller and at the same time, save the bandwidth between the base station controller and the core network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for realizing local switching in a base station controller, core network equipment and a network system. Background technique [0002] Universal Mobile Telecommunications System (UMTS) is the protocol standard of the third generation mobile communication system specified by 3GPP. The UMTS network includes: Core Network (Core Network, CN), UMTS Terrestrial Radio Access Network (UMTS Terrestrial Radio AccessNetwork , UTRAN) and user equipment (UE, User Equipment). Wherein, the UTRAN is composed of a radio network controller (Radio Network Controller, RNC) and a NodeB. The core network CN can be logically divided into a packet-switched domain (PS) and a circuit-switched domain (CS). The CS domain is the circuit-switched core network of UMTS for supporting voice services; the PS domain is the It is used to support packet data services and some multimedia services. ...

AI Technical Summary

Problems solved by technology

[0018] In the prior art, both the CS domain service and the PS domain service of the UMTS system must pass through the core network, but if both communication parties are located under the same RNC, it is unnecessary for the user plane data exchange between the two communication parties to pass through the core network , causing a large delay, and also causing unnecessary occupation of the bandwidth between the RNC and the core network
