SYSTEM AND METHOD FOR IMPLEMENTING MOBILE IP NODE LOSSLESS TRANSITION FROM AN IDLE STATE TO AN AWAKE STATE
First Claim
1. A method of enabling the preservation of data intended for a mobile station in a network when the mobile station is in an idle state, comprising:
- receiving a request to assign a Care of Address (CoA) to the mobile station when the mobile station enters the idle state;
selecting an appropriate CoA for the mobile station;
receiving a data packet intended for the mobile station; and
forwarding the data packet to the CoA.

Abstract
A system and method for implementing a “lossless” transition from an idle state to an active or awake state in a mobile station. When a mobile station informs a serving base transceiver station that it is switching to an idle state, a virtual handover is executed, with the mobile station receiving a new Care of Address (CoA). The CoA is taken from an address space that is solely reserved for idle mobile station in a particular access network. The CoA is used to store data packets that are to be transmitted to the mobile station. Once the mobile station reenters an active state, the buffered packets can be forwarded to the mobile station without packet loss.

18. A system in a network, comprising:
-
a mobile station configured to operate in an idle state and a live state; a first base transceiver station at least selectively communicatively connected to the mobile station; and an access network gateway at least selectively communicatively connected to the mobile station, the access network gateway configured to receive from the first base transceiver station a request to assign a Care of Address (CoA) to the mobile station when the mobile station enters the idle state, select an appropriate CoA for the mobile station, and forward a data packet intended for the mobile station to the CoA when the mobile station is in the idle state. - View Dependent Claims (19, 20, 21, 22, 23)

24. A method of enabling the preservation of data intended for a mobile station in a network when the mobile station is in an idle state, comprising:
-
indicating to a first base transceiver station that the mobile station is to enter an idle state; in response to the indication, receiving from the first base transceiver station a Care of Address (CoA), the CoA assigned by an access network gateway. - View Dependent Claims (25, 26, 27, 28, 29, 30)
