Method for determining target, network element and system for determining target

Abstract

The embodiment of the invention discloses a method for determining a target, a network element and a system for determining the target, relating to the technical field of communications, and aiming atsolving the problems that user equipment is not allowed to access the network and cannot obtain services, the network access delay is too long, the user attachment rate of operators is low, and the roaming cost of the user equipment is too high. The method includes the following steps: an access network element receives access control information of user equipment (UE) sent by a mobility management network element, wherein the access control information includes an identifier of a public land mobile network (PLMN) and a radio access type (RAT) that is allowed and / or not allowed by the PLMN; and the access network element determines the target for the UE according to the access control information. The scheme of the invention can be applied to a shared network environment.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for determining a target, a network element and a system for determining a target. Background technique [0002] At present, most network operators achieve the goal of saving operating costs by sharing network architecture, such as Gateway Core Network (GWCN for short), and Multi-Operator Core Network (Multi-Operator Core Network, MOCN for short). Or save operating costs through roaming, for example, operators only deploy LTE networks, and users on this network access other operators' 2G / 3G networks through roaming. [0003] In the environment where multi-operator networks coexist, the general access network element determines the target network operator based on the currently used public land mobile network (Public Land Mobile Network, PLMN for short) and other information when determining the target for the UE and migrating users. Or the RAT is used for user eq...

Problems solved by technology

[0008] Embodiments of the present invention provide a method for determining a target, a network element, and a system for determining a target, which can solve the problem that in the prior art, user equipment cannot access a certain access technology in a certain PLMN, resulting in an increase in network access delay , the problem of affecting user experience, it can also solve the problem of low user attachment rate and poor brand building of operators in some scenarios, and also solve the problem of high roaming fees of UE
