  • Patent number: 8391874
    Abstract: A method for updating location of a user equipment in a cellular system is disclosed. The method comprises the user equipment receiving route update radius information 220. The user equipment further calculates a route update radius from the received route update radius information 230 by using a random number generated by the user equipment. The user equipment then transmits the calculated route update radius to a cellular network 240. Alternatively, the method comprises the cellular network receiving a route update message from a user equipment 420. The cellular network further calculates a route update radius 430 using a random number generated by the cellular network. The cellular network then unicasts the calculated route update radius to the user equipment 440.

  • Patent number: 8220044
    Abstract: The invention relates to a method for triggering re-negotiation of a session when an Access Terminal moves from one access network (source AN) to another access network (target AN) having different capabilities in high rate packet data system. According to an exemplary embodiment of the invention, the source AN is allowed to store all the protocol subtypes, protocols and applications that AT is capable of and also allowing the AT to send this information in priority order during session negotiation and hence facilitating the transfer of this information from source AN to target AN during session transfer when AT moves from one AN to another AN. An alternate embodiment is to let the AT send the protocol subtypes, protocols and applications and other AT capable information to target AN after it moves to a new AN or by letting the Rev-A capable AN query the AT's capability information and then the AT providing this information.
