System and method for transparent mobile IP registration within PPP negotiation

A method performed by a wireless device to provide a second device with an IP address assigned by a wireless network entity, comprising:

• receiving a configuration request message from the second device during a communication session for obtaining an IP registration and prior to a mobile IP session between the wireless device and the wireless network entity, where the configuration request message comprises a request for an assignment of an IP address;
• stripping the request for the assignment of the IP address in the configuration request message from the second device to define an altered configuration request message;
• transmitting the altered configuration request message to the wireless network entity for network-layer protocol configuration between the second device and the wireless network entity;
• and
• keeping the second device active so as not to terminate the communication session with the wireless device while waiting for the assigned IP address to be received during a wireless communication session with the wireless network entity.

An apparatus for use in a wireless device to provide a second device with an IP address assigned by a wireless network entity, comprising:

• a receiver configured to receive a configuration request message from the second device during a communication session for obtaining an IP registration and prior to a mobile IP session between the wireless device and the wireless network entity, where the configuration request message comprises a request for an assignment of an IP address;
• a processor configured to strip the request for the assignment of the IP address in the configuration request message from the second device to define an altered configuration request message;
• a transmitter configured to transmit the altered configuration request message to the wireless network entity for network-layer protocol configuration between the second device and the wireless network entity;
• and
• wherein the processor is further configured to keep the second device active so as not to terminate the communication session with the apparatus while waiting for the assigned IP address to be received during a wireless communication session with the wireless network entity.
