Validating user identity by cooperation between core network and access controller

摘要

An identifier, required by a radio access network controller in order to support resource allocation associated with a predetermined condition, is sent from a core network to the radio access network controller independently of the predetermined condition. The identifier is thus available to the radio access network controller for verification of mobile user identity, regardless of whether it is needed to support resource allocation. A radio access network controller can receive an identifier in a communication sent by a core network according to a communication protocol. The radio access network controller terminates the communication protocol to access the communication, and uses the identifier for verification of mobile user identity.
