Network element and method for providing access control for a cellular communication network
First Claim
1. A network element for providing access control to a core network of a cellular communication network for a wireless communication unit operating within a communication cell supported by the network element, wherein the network element comprises:
- a receiver for receiving a message from the wireless communication unit comprising identity information;
logic, operably coupled to the receiver, for determining whether to permit the mobile communication unit access to the core network, based at least in part on the received identity information and whether to forward the message to the core network;
wherein if the logic determines not to forward the message comprising identity information to the core network, but the wireless communication unit is permitted access to the core network, the logic is arranged to construct and send a null message to the core network with a same sequence number as that of the message received from the wireless communication unit.

Abstract
A network element (130, 330), for providing access control to a core network (120) of a cellular communication network (100) for a wireless communication unit (150) operating within a communication cell supported by the network element (130, 330), comprises a receiver for receiving a message (425) from the wireless communication unit (150) comprising identity information. The network element further comprises logic (160), operably coupled to the receiver, for determining whether to permit the mobile communication unit (150) access to the core network (120), based at least in part on the received identity information.

15. A method for providing access control to a core network of a cellular communication network for a wireless communication unit operating within a communication cell supported by the network element, the method comprising:
-
receiving a message from the wireless communication unit comprising identity information; determining whether to permit the wireless communication unit access to the core network, based at least in part on the received identity information and whether to forward the message; and if it is determined not to forward the message to the core network, but that the wireless communication unit is permitted access to the core network; constructing and sending additionally a null message to the core network with a same sequence number as that of the message received from the wireless communication unit.

16. A non-transitory computer readable medium having computer readable instructions stored thereon for execution by a processor to perform a method for providing access control to a core network of a cellular communication network for a wireless communication unit operating within a communication cell supported by the network element, the method comprising the steps of:
-
receiving a message from the wireless communication unit comprising identity information; determining whether to permit the wireless communication unit access to the core network, based at least in part on the received identity information and whether to forward the message; and if the logic determines not to forward the message to the core network, but tha the wireless communication unit is permitted access to the core network constructing and sending additionally a null message to the core network with a same sequence number as that of the message received from the wireless communication unit. - View Dependent Claims (17)
