Abstract
Enabling a standard cellular handset to be used to access a core mobile network via a generic access network is disclosed. A communication between a generic access network element and the core mobile network is intercepted. A modified version of the communication is generated. The modified communication is forwarded.
Claims20
A mobile network element, comprising:
- a communication interface;
- and
- a processor operatively coupled to the communication interface and configured to intercept a communication between a generic access network (GAN) element and a core mobile network, to generate a modified version of the communication, and to forward the modified version of the communication via the communication interface,
- wherein the mobile network element comprises a GAN adjunct (GCA), wherein a GAN controller (GANC) is communicatively disposed between an aggregation gateway (AGW) and the GCA, and
- wherein the GCA and the AGW have a bypass connection that bypasses the GANC, and
- wherein the bypass connection carries handover requests that are forwarded to the processor.
3 more elements
A cellular communications system, comprising:
- an aggregation gateway (AGW);
- a generic access network controller (GANC) operatively coupled to the AGW;
- and
- a GAN adjunct (GCA) operatively coupled to the GANC, wherein the GCA is configured to intercept a communication between a GAN element and a core mobile network, to generate a modified version of the communication, and to forward the modified version of the communication via a communication interface,
- wherein the GANC is communicatively disposed between the AGW and the GCA,
- wherein the GCA and the AGW have a bypass connection that bypasses the GANC, and
- wherein the bypass connection carries handover requests.
4 more elements
A method for enabling a mobile station to be used to access a core mobile network via a generic access network, comprising:
- receiving an indication that a handover into a service area associated with the generic access network is to be performed;
- providing to a node on the mobile station side of a Generic Access Network (GAN) element located in a call data path between the mobile station and the core mobile network, via an interface that bypasses the GAN element, an attribute of the mobile station, the node being configured to use the attribute to establish, on behalf of the mobile station, a secure connection to the generic access network element, wherein the attribute is provided, at least in part, by intercepting and forwarding to the node, via the bypass interface, a handover request message sent by the core mobile network to the generic access network element.
