Method for determining whether to grant access of a user equipment to a radio access network
First Claim
1. Method for determining whether to grant access of a user equipment (UE) to a radio access network in a present position of the user equipment (UE) within a communications system, the communications system comprising a control node (N1, N2) handling services for the user equipment (UE) and an access node (AN1, AN2) controlling the access network, the method comprising the steps of receiving a request for service processing for the user equipment (UE) in the control node (N1, N2) with an identification of the user equipment (UE), determining a subscriber group information for the user equipment (UE) according to the identification of the user equipment, sending the subscriber group information to the access node (AN1, AN2), determining an area access information according to the present location of the user equipment (UE) in the access node (AN1, AN2), and performing the access granting of the user equipment (UE) to the radio access network according to a logical combination of the subscriber group information and the area access information.

Abstract
The invention concerns a method for determining whether to grant access of a user equipment (UE) to a radio access network in a present position of the user equipment (UE) within a communications system. The communications system comprises a control node (N1, N2) handling services for the user equipment (UE) and an access node (AN1, AN2) controlling the access network. The method is initiated by receiving a request for service processing for the user equipment (UE) in the control node (N1, N2) with an identification of the user equipment (UE). A subscriber group information is determined for the user equipment (UE) according to the identification of the user equipment and sent to the access node (AN1, AN2). Furthermore, an area access information according to the present location of the user equipment (UE) is determined in the access node (AN1, AN2). The access granting of the user equipment (UE) to the radio access network is performed according to a logical combination of the subscriber group information and the area access information. A communication network, nodes and software programs embodying the invention are also described.
