Access network type identification in mobile internet protocol (MIP) registration (RRQ)

摘要

A wireless communication device identifies the access network type in the Mobile IP (MIP) Registration Request (RRQ). The wireless communication device uses a wireless communication network to access the IP communication network. The wireless communication device initiates a switch to another wireless communication network. In response to initiating the switch, the wireless communication device determines the network type of the new wireless communication network and generates a MIP RRQ identifying the access network type. After the MIP Registration Response (RRP) is received, the wireless communication device sends and retrieves IP data with the IP communication network via the new wireless communication network.

1. A method of operating a wireless communication device, the method comprising:
identifying an eNodeB in a Long Term Evolution (LTE) network; exchanging wireless network data with a wireless network access node in a wireless communication network; generating a Mobile Internet Protocol (MIP) Registration Request (RRQ) identifying the eNodeB in the LTE network and the wireless access node in the wireless communication network, wherein generating the MIP RRQ identifying the eNodeB comprises generating the MIP RRQ including an LTE Physical Cell Identification (PCI); transferring the MIP RRQ to the eNodeB in the LTE network for delivery to an Internet Protocol (IP) network; and exchanging IP data with the IP network over the eNodeB.
