Abstract
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.
