Problems solved by technology

[0007] 1. It cannot solve how to select the core network operator and the corresponding core network for the UE that does not support the network sharing feature when the core network matched by the RNC according to the NRI fails
[0008] 2. When the RNC cannot select the core network according to the NRI, it will easily lead to failure of user attachment or location registration by means of random selection
Moreover, this processing method of randomly selecting the core network operator will lead to an increase in the load of the RNC, which has a great impact on the performance of the RNC

Embodiment Construction

[0038] Before implementing the present invention, it is necessary to set up the corresponding relationship between NRI and core network operator PLMN ID (public land mobile network identification) in RNC, including:

[0039] Establish the corresponding relationship between the NRI and the PLMN ID of a core network operator, and the sharing relationship between the core network operator and other core network operators in the MOCN networking.

[0040] Among them, establishing the sharing relationship between the core network operator corresponding to the NRI and other core network operators in the MOCN network includes:

[0041] 1. Establish the corresponding relationship between the PLMN ID of the core network operator and the PLMN IDs of other core network operators in the MOCN networking.

[0042] 2. Allocate priorities to all core network operators with sharing relationships. If no explicit priority is assigned, the same priority is indicated.

[0043] Through the above s...

Abstract

The invention relates to a method for selecting corn network based on NRI, wherein it is characterized in that: when the user device that not support network share processes position register request, route region refresh request, and adhere request, the wireless network controller RNC selects relative corn network for UE; when the selected corn network is accident, said RNC is best to select other corn networks of corn network operator relative to the corn network; when the RNC can not select the corn network based on NRI, the invention selects the corn network that the NRI can match, to avoid the fail of user adhere or position register caused by random selection, and avoid the load increase of whole network, to affect the property of whole network.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for selecting a core network according to a network resource identification code. Background technique [0002] The 3GPP TS 23.251 standard of the 3GPP Release6 protocol introduces the concept of MOCN (Multi-Operator Core Network, multi-operator core network), and proposes that in the presence of MOCN, the UE that does not support the network sharing feature selects the core through the RNC Network method, the implementation process is as follows: [0003] After the RNC receives the Initial Direct Transfer (initial direct transfer) message sent by the UE, it adds a redirect attempt flag set (core network routing reselection identifier) ​​on the basis of the NAS (non-access stratum) part of the message, and then judges that the The IDNNS (IntraDomain NAS Node Selector, intra-domain non-access layer node selection parameter) in the Initial Direct Transfer message is derived from...
