Method and system for rerouting and access network device

Abstract

An embodiment of the invention relates to a method and a system for rerouting and an access network device. The method comprises the steps: the access network device sends an accessing request message to a core network device of a first operator; if the access network device receives a first response message carrying first reason information and sent by the core network device of the first operator and the first reason information is included in rerouting reason information configured by the access network device, the access network device sends the accessing request message to the core network device of the first operator, wherein the first reason information is used for representing reasons why user device accessing is rejected by the core network device of the first operator, and the access network device is shared by the first operator and a second operator. The method and the system for rerouting and the access network device can decrease interactive messages in the rerouting process.

Description

technical field [0001] The present invention relates to the communication field, in particular to a rerouting method, system and access network equipment. Background technique [0002] In a multi-operator core network (Multi-Operator Core Network, MOCN) network, different operators can share access network equipment while having their own independent core networks. When the cell is a MOCN shared cell, a user equipment (User Equipment, UE) accessing the cell may select one of core network devices of multiple operators sharing the cell to establish a connection. In the MOCN network, rerouting means that after the core network equipment of the initially selected operator cannot be accessed by the user equipment, the access network equipment re-selects the core network equipment of other operators for access. [0003] In the prior art, in the circuit switched (Circuit Switched, CS) domain, when the access network device sends an access request message to the core network device...

AI Technical Summary

Problems solved by technology

However, in the MOCN network, two additional messages, Reroute Command and Reroute Complete, need to be used between the access network device and the operator's core network device to complete the rerouting process. Therefore, the rerouting process is relatively complicated.
