Patent ID: 8185107

Claim:
A networking system, comprising: a first wireless network module configured to transmit a request to attach to a network; and a second wireless network module configured to: receive the request; determine whether the first wireless network module requires an IP address based on the request; and selectively allocate the IP address to the first wireless network module based on the determination, wherein the request includes an indication of whether the first wireless network module requires the IP address; if the request indicates that the first wireless network module requires the IP address, the second wireless network module allocates the IP address to the first wireless network module based on the request; and if the request indicates that the first wireless network module does not require the IP address, the second wireless network module does not allocate the IP address to the first wireless network module; the first wireless network module attaches to the network without receiving the IP address; after attaching to the network, the first wireless network module obtains the IP address from a third wireless network module; and the first wireless network module modifies a bearer context based on the IP address obtained from the third wireless network module.
