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.
