  • REGISTERING A MOBILE COMMUNICATION DEVICE WITH AN ACCESS NETWORK
    Publication number: 20090161624
    Abstract: A method (500, 600, 700) of registering a mobile communication device (102, 104, 106, 108) with an access network (112) can include receiving a request for a client mobile internet protocol (IP) registration from the mobile communication device. The method can also include performing a proxy mobile IP registration on behalf of the mobile communication device and sending a confirmation of the client mobile IP registration to the mobile communication device.

  • Apparatus and method for performing forced registration of a mobile station after hard handoff
    Patent number: 6804518
    Abstract: In a network supporting concurrent services, mobile terminated call delivery processing is simplified by an apparatus and method for forcing a Mobile Station (MS) (118) to register with a new Mobile Switching Center (MSC) (110) after a hard handoff has occurred. The mobile station registers with the new MSC when the mobile station is in an active data call, but not in an active voice call. The method momentarily sends the data session to dormant mode while the mobile station performs location updating. The method utilizes a new information element in a Clear Command message that allows the MSC to indicate to the Base Station Controller (112) that the period a data session must remain dormant should be very brief. This brief period of time limits the impact on the MS user.
