Managing termination of point-to-point sessions between electronic devices
View Patent ↗Proxy mobile IP provides mobility to a mobile device that is not equipped to perform client mobile IP by moving the mobile IP signaling responsibility from the mobile device into the network. A network element performs the mobile IP signaling on behalf of the mobile device. In one scenario, the mobile device establishes a PPP session with a foreign agent, with no mobile IP signaling on top of the PPP session. The foreign agent then performs mobile IP signaling with the mobile device's home agent to negotiate a proxy mobile IP session for the device. Once the session registration lifetime has been established by the foreign agent and the home agent, the foreign agent communicates the registration lifetime to the mobile device by way of a PPP vendor-specific packet.
1. One or more nontransitory computer-readable media having embodied thereon computer-usable instructions that, when executed, facilitate a method of communicating a value of a registration lifetime to a mobile device for a proxy mobile IP session, the method comprising:
receiving a registration request from the mobile device to register with a home agent associated with the mobile device;
negotiating the proxy mobile IP session with the home agent on behalf of the mobile device by utilizing a mobile IPv4 protocol;
establishing the registration lifetime with the home agent; and
communicating the value of the registration lifetime to the mobile device.
2. The media of claim 1 , wherein a network element negotiates the proxy mobile IP session with the home agent on behalf of the mobile device.
3. The media of claim 2 , wherein establishing the registration lifetime with the home agent includes receiving, at the network element, the value of the registration lifetime from the home agent, via the mobile IPv4 protocol.
4. The media of claim 2 , wherein communication between the network element and the mobile device utilizes point-to-point protocol (PPP).
5. The media of claim 4 , wherein communication between the network element and the mobile device does not utilize mobile IP signaling.
6. The media of claim 2 , wherein negotiating the proxy mobile IP session includes utilizing mobile IP signaling between the network element and the home agent, and wherein the mobile IP signaling is carried over a point-to-point protocol (PPP) session.
7. The media of claim 6 , wherein the mobile device is not mobile-IP enabled.
8. The media of claim 2 , wherein the network element is a foreign agent.
9. The media of claim 2 , wherein the network element is a packet data serving node (PDSN).
10. A method of communicating a value of a registration lifetime to a mobile device for a proxy mobile IP session, the method comprising:
receiving a registration request from the mobile device to register with a home agent associated with the mobile device;
negotiating the proxy mobile IP session with the home agent on behalf of the mobile device by utilizing a mobile IPv4 protocol;
establishing the registration lifetime with the home agent; and
communicating the value of the registration lifetime to the mobile device.
11. The method of claim 10 , wherein a network element negotiates the proxy mobile IP session with the home agent on behalf of the mobile device.
12. The method of claim 11 , wherein establishing the registration lifetime with the home agent includes receiving, at the network element, the value of the registration lifetime from the home agent, via the mobile IPv4 protocol.
13. The method of claim 11 , wherein communication between the network element and the mobile device utilizes point-to-point protocol (PPP).
14. The method of claim 13 , wherein communication between the network element and the mobile device does not utilize mobile IP signaling.
15. The method of claim 11 , wherein negotiating the proxy mobile IP session includes utilizing mobile IP signaling between the network element and the home agent, and wherein the mobile IP signaling is carried over a point-to-point protocol (PPP) session.
16. The method of claim 15 , wherein the mobile device does not participate in the mobile IP signaling between the network element and the home agent.
17. The method of claim 11 , wherein the network element is a foreign agent.
18. The method of claim 11 , wherein the network element is a packet data serving node (PDSN).
