Embodiment Construction

[0038] Before introducing the communication system, the access network and the method for controlling user equipment access provided by the embodiments of the present invention, a brief introduction will be made to the existing access control method of the access network and the access control method of the core network:

[0039] 1. The existing access network only performs access control on UEs of a specific version, and this method may be IMSI-based access control. Wherein, the access control entity (base station and / or gateway) of the access network stores the IMSIs of all UEs that can pass the access control, and the UE sends the IMSI to the access control entity during the access request process, If the UE is in the Allowed IMSI List (a set of IMSIs stored on the access control entity for access control), the UE's access request is passed; otherwise, the UE's access request is rejected.

[0040] 2. Since HNB is a private device, outsiders are not expected to use it withou...

Abstract

A communication system, an access control entity and a method for controlling User Equipment (UE) access are disclosed. The present invention relates to communication technologies and aims to improve network security. The method includes: receiving an access request from a UE which depends on access control exercised by a core network; exercising access control on the UE if no core network capable of exercising access control can be selected for the UE; and sending a connection request to the core network if a core network capable of exercising access control can be selected for the UE. The technical solutions of the present invention are widely applicable to communication systems such as Universal Mobile Telecommunications System (UMTS) and Long Term Evolution (LTE).

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a communication system, an access control entity and a method for controlling user equipment access. Background technique [0002] In UMTS (Universal Mobile Telecommunications System, universal mobile communication system) and LTE (Long-term Evolution, long-term evolution network), before the UE (User Equipment, user equipment) obtains the service provided by the communication network, the UE must first pass the registration process After registering into the system, the network performs access control on the UE according to the information reported by the UE during the registration process, that is, to determine whether the UE has the right to register with the network. [0003] In the existing network, the access network mainly determines which access control mode to adopt and which network elements to perform access control according to the version information o...
