Abstract

A communications system is described in which a core network apparatus provides a configuration for accessing a packet data network by a mobile communications device when operator determined barring is in place. Also disclosed are signalling messages used to control the setting up of the packet data connection, which messages are sent between a device in the core network and the mobile communications device.

Claims

1. A network node for use in a communications system having a core network and at least one communications device, the network node comprising:

a controller comprising memory and one or more processors configured to;

generate control information for controlling access of the at least one communications device to packet data services that use the core network, wherein the control information identifies at least one gateway and indicates that the at least one communications device is barred from using the at least one identified gateway;

communicate with the at least one communications device including a controller, comprising memory and one or more processors, configured to;

communicate with the generated control information,

monitor communications by the at least one communications device relating to packet data services, and

communicate the control information to the at least one communications device upon the controller indicating a communication attempt by the at least one communication device relating to packet data services that use the at least one identified gateway; and

obtain subscription data from a home subscriber server, the subscription data indicating whether an operator determined barring has been invoked for the at least one communications device, wherein the subscription data comprises a list of barred gateways for the at least one communications device.

2. The network node according to claim 1, wherein the communication attempt comprises a request for a new packet data service that uses the at least one identified gateway and wherein the control information comprises a rejection of the communication attempt.

3. The network node according to claim 1, wherein the communication attempt comprises communication relating to an existing packet data service that uses the at least one identified gateway and wherein the control information comprises a termination of the existing packet data service that uses the at least one identified gateway.

4. The network node according to claim 3, wherein the controller comprising memory and one or more processors is further configured to instruct a network node controlling the at least one identified gateway to terminate the existing packet data service.

5. A communications system comprising:

a core network;

at least one communications device, and

a network node comprising;

a controller comprising memory and one or more processors configured to;

generate control information for controlling access of the at least one communications device to packet data services that use the core network, wherein the control information identifies at least one gateway and indicates that the at least one communications device is barred from using the at least one identified gateway;

communicate with the at least one communications device including a controller, comprising memory and one or more processors, configured to;

communicate with the generated control information,

monitor communications by the at least one communications device relating to packet data services, and

communicate the control information to the at least one communications device upon the controller indicating a communication attempt by the at least one communication device relating to packet data services that use the at least one identified gateway; and

obtain subscription data from a home subscriber server, the subscription data indicating whether an operator determined barring has been invoked for the at least one communications device, wherein the subscription data comprises a list of barred gateways for the at least one communications device.

6. A method performed by a network node in a communications system having a core network and at least one communications device, the method comprising:

generating control information for controlling access of the at least one communications device to packet data services that use the core network, wherein the control information identifies at least one gateway and indicates that the at least one communications device is barred from using the at least one identified gateway;

communicating with the at least one communications device including a controller, comprising memory and one or more processors, configured to communicate with the generated control information;

monitor communications by the at least one communications device relating to packet data services;

communicate the control information to the at least one communications device upon the controller indicating a communication attempt by the at least one communication device relating to packet data services that use the at least one identified gateway; and

obtaining subscription data from a home subscriber server, the subscription data indicating whether an operator determined barring has been invoked for the at least one communications device, wherein the subscription data comprises a list of barred gateways for the at last one communications device.

7. A non-transitory computer-readable storage medium storing instructions for enabling a computer to implement method performed by a network node in a communications system having a core network and at least one communications device, the method comprising:

generating control information for controlling access of the at least one communications device to packet data services that use the core network, wherein the control information identifies at least one gateway and indicates that the at least one communications device is barred from using the at least one identified gateway;

communicating with the at least one communications device including a controller, comprising memory and one or more processors, configured to communicate with the generated control information;

monitor communications by the at least one communications device relating to packet data services;

communicate the control information to the at least one communications device upon the controller indicating a communication attempt by the at least one communication device relating to packet data services that use the at least one identified gateway; and

obtaining subscription data from a home subscriber server, the subscription data indicating whether an operator determined barring has been invoked for the at least one communications device, wherein the subscription data comprises a list of barred gateways for the at least one communications device.
