Patent ID: 8867505

Claim:
A fast data call connection method between a Mobile Station and a Node serving packet data in a wireless network, comprising: transmitting a first message containing an authentication type and a challenge value thereof to the Mobile Station by the Node; transmitting a second message containing an authentication response to the authentication type and the challenge value to the Node by the Mobile Station; transmitting a third message to the Mobile Station by the Node, when authentication of the Mobile Station is successfully performed by using the authentication response, wherein at least one of the second message and the third message contain at least one IP (Internet Protocol) address information assigned for the Mobile Station; and exchanging packet data between the Mobile Station and the Node over a data link in point-to-point protocol (PPP), wherein the data link in the PPP is connected between the Mobile Station and the Node by exchanging the first message, second message and third message, and wherein the fast data call connection method, before the transmission of the first message, further comprises negotiating a session with protocol ID, which indicates a fast data call connection, between the Mobile Station and an Access Network(AN); sending a service option for the fast data call connection, to the Node by the AN; and receiving the service option and recognizing the Mobile Station supports fast data call connection, by the Node.
