ABSTRACT:
A communication system can include an access network, a core network, and user equipment for connection to the core network through the access network. The access network can be configured to receive a request for network access from the user equipment, to receive network access information from the core network, to selectively control access to the core network for the user equipment in dependence on the network information, to identify a request for an emergency call, and to disable the selective control of access to the core network responsive to identification of an emergency call.
