Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0046] When the UE roams into the wireless area of ​​the shared network, the UE finds that the location area identifier in the broadcast information has changed, and needs to initiate a location update process to re-register at this time. The method of the present invention is applied to the location update process, the main process is as follows image 3 shown.

[0047] 301. The UE establishes a wireless connection with the RNC

[0048] 302. The UE sends an Initial Direct Transfer message to the RNC.

[0049] If the RNC cannot obtain the NRI in the message, or obtains but cannot find the corresponding MSC, and the message does not carry the PLMN-ID selected by the UE, the RNC cannot determine the MSC and needs to select the MSC for the first route reselection.

[0050] 303. The RNC decodes the Initial Direct Transfer message to obtain a no...

Abstract

The invention discloses a route reselection method and a radio network controller. The method is applied in a multi-operator core network, when the radio network controller, that is the RNC receives an initial direct transfer message sent by a user device, a mobile switching center, that is the MSC is selected for carrying out route reselection. When the RNC decodes a non-access layer message in the initial direct transfer message and a position updating request message is obtained, the RNC obtains a core network operator identifier carried in the position updating request message, that is PLMN-ID information; and the RNC selects the MSC for carrying out the first route reselection according to the PLMN-ID information and the corresponding relationship between the PLMN-ID and the MSC configured in the RNC. The use of the method can ensure the consistency of operators of the core network selected for UE and the operators of the core network for serving the UE during the last position updating before roaming of the UE, and improve the success probability of the first route reselection.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and a device for selecting a mobile switching center when rerouting in a multi-operator core network. Background technique [0002] The network sharing technology in 3G Wideband Code Division Multiple Access (WCDMA) refers to allowing different network operators to share a part of WCDMA network elements. Currently, there are various solutions for network sharing, among which there is an important network sharing method: each operator builds an independent core network, but shares a radio access network (RAN) and a frequency band. This network sharing method involves the Iu-Flex technology in the 3GPP protocol and a multi-operator core network (Multi-Operator Core Network, MOCN) networking method. [0003] The introduction of Iu-Flex technology breaks the previous relationship that the radio network controller (RNC) can only be controlled by one core network node mo...
