Access control methods and apparatus for radio systems
View Patent ↗A wireless terminal communicates to an access node which is connected to a first core network and a second core network. The wireless terminal comprises receiver circuitry, processor circuitry, and transmitter circuitry. The receiver circuitry is configured to receive from the access node first access control information and to separately receive from the access node second access control information. The processor circuitry is configured to perform, based on the first access control information, an access control procedure for the first core network, and to perform, based on the second access control information, an access control procedure for the second core network. The transmitter circuitry is configured to transmit an access request according to access control information.

perform, based on the first access control information, an access control procedure for the first core network, and to perform, based on the second access control information, an access control procedure for the second core network; and
transmitter circuitry configured to transmit an access request; wherein
in case that an access attempt is allowed by the access control procedure for the first core network, the transmitter circuitry is configured to transmit, to the access node, an access request for the first core network, and
in case that the access attempt is barred by the access control procedure for the first core network and an access attempt is allowed by the access control procedure for the second core network, the transmitter circuitry is configured to transmit, to the access node, an access request for the second core network.
2. The wireless terminal of claim 1 , wherein the first core network is 5G Core Network (5GCN) and the second core network is Evolved Packet Core network (EPC).
3. A method in a wireless terminal communicating with an access node, the access node being connected to a first core network and a second core network, the method comprising:
receiving from the access node first access control information and separately receiving from the access node second access control information;
performing, based on the first access control information, an access control procedure for the first core network,
performing, based on the second access control information, an access control procedure for the second core network; wherein
in case that an access attempt is allowed by the access control procedure for the first core network, transmitting, to the access node, an access request for the first core network; and
in case that the access attempt is barred by the access control procedure for the first core network and the access attempt is allowed by the access control procedure for the second core network, transmitting, to the access node, an access request for the second core network.
4. The method of claim 3 , wherein the first core network is 5G Core Network (5GCN) and the second core network is Evolved Packet Core network (EPC).
5. An access node of a radio access network which is connected to a first core network and a second core network, the access node comprising:
processor circuitry configured to generate a first access control information for the first core network and separately to generate a second access control information for the second core network;
the first access control information comprising access control parameters configured to be used for evaluation by a wireless terminal in determining whether an access attempt is allowed or barred for the first core network;
the second access control information comprising access control parameters configured to be used for evaluation by the wireless terminal in determining whether an access attempt is allowed or barred for the second core network; and
transmitter circuitry configured to transmit the first access control information and the second access control information over a radio interface to the wireless terminal.
