摘要： A communication system that allows a soft handoff to be completed, even when the communications link between the active base station and the mobile station deteriorates before the mobile station has received the handoff direction message. The mobile station maintains a list of base stations that the mobile station is in communication with, referred to as an “Active Set”. In addition, the mobile station maintains another list of base stations that are proximate to the base stations in the active set. This list is referred to as the “Neighbor Set”. In accordance with the disclosed method and apparatus, the mobile station places a base station in the active set upon including the base station in a pilot strength measurement message (PSMM). The mobile station monitors transmissions from all of the base stations on the active set to receive a handoff direction message (HDM).

摘要： Access terminal identification management providing a minimum distance between subnets before reusing subnet identifiers. Mobility criteria evaluation determines when to reassign an access terminal identifier. In one embodiment, the mobility criteria is whether any member of the active set for the access terminal belongs to an originating subnet. In an alternate embodiment, the criteria is whether the access terminal has traveled more than a minimum distance from the originating subnet. When a mobility criteria is violated, the access network assigns a new identifier. In one embodiment, the access terminal identifier is a long code mask based on a subnet identifier. Identifier management applies when crossing sector boundaries in a cellular system, and serves to reduce the ambiguity of mapping CC values to full UATI values, and to avoid overlapping assignments.
