First Claim
Patent Images
1. A method for Mobile Internet Protocol (IP) registration by a wireless device on a wireless wide area network, the method comprising:
- handing off to a first access point served by a first network access server that provides Mobile IP service;
after handing off to the first access point, registering with the first network access serverafter registering with the first network access server, handing off to a second access point served by a second network access server that provides Mobile IP service; and
after handing off to the second access point, waiting a predetermined amount of time after registering with the first network access server before registering with the second network access server.

Abstract
A network access server, such as a PDSN, might provide Mobile IP services to one or more access points for a wireless wide area network. A wireless device might handoff to an access point served by the network access server, and the wireless device might receive from the access point an identifier, such as a Packet Zone ID, that identifies the network access server. The wireless device might then register with the access server but delay making any subsequent Mobile IP re-registrations until after a predetermined amount of time.

12. A method for a wireless device handing off between base stations in a wireless wide area network to register for Mobile Internet Protocol (IP) services, the method comprising:
-
handing off to a first base station in the wireless wide area network; receiving from the first base station a first packet zone identification (ID) corresponding to a first packet data serving node (PDSN) providing Mobile IP services to wireless devices served by the first base station and also receiving a timer value associated with the first packet zone ID; making a Mobile IP registration with the first PDSN; starting a timer having a duration corresponding to the timer value; and delaying any Mobile IP re-registrations with PDSNs other than the first PDSN until after the timer expires. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A wireless device comprising:
-
a processor; memory; logic stored in the memory and executable by the processor to i) handoff to a first base station in a wireless wide area network, ii) receive from a first base station a first packet zone identification (ID) corresponding to a first packet data serving node (PDSN) providing Mobile Internet Protocol (IP) services to wireless devices served by the first base station and a timer value associated with the first packet zone ID, iii) initiate a Mobile IP registration with the first PDSN, iv) start a timer having a duration corresponding to the timer value, and v) wait until the timer expires before initiating a Mobile IP re-registration with a PDSN other than the first PDSN. - View Dependent Claims (20)
