METHOD AND SYSTEM FOR SERVICE ACCESS CONTROL IN SHARED NETWORKS

摘要

In a method of sharing a Radio Access Network, RAN, in one or more areas by at least two operators the determination whether to grant admission or not of a User Equipment, UE, to the RAN is performed in an admission control algorithm. A Radio Network Controller, RNC, is reading Network Resource Identifier, NRI, information contained in an "Initial Direct Transfer" message sent by the UE when requesting a service, and the read NRI information is used in a service admission control to check a plurality of service admission parameters as a part of a set of admission control parameters to grant or reject the requested service depending on whether the operator associated with the NRI has invested in needed technology or not. A corresponding radio access network comprises admission control means to determine whether to grant admission of a User Equipment, UE, to the network, RAN, or not. A Radio Network Controller, RNC, is arranged to read NRI, information contained in the "Initial Direct Transfer" message sent by an UE, when requesting a service, and sending the read NRI information to the admission control means to check a plurality of service admission parameters as a part of a set of admission control parameters to grant or reject the requested service depending on whether the operator associated with the NRI has invested in needed technology or not.
