Abstract
A method is disclosed that can be carried out in an access network comprising a plurality of coverage areas, each coverage area being served by an RNC. The method involves making a determination that an access terminal is located in an inter-RNC boundary zone, and then, during a communication session: (i) determining that a handoff from a source coverage area to a target coverage area should be performed; (ii) determining whether or not the target coverage area is served by the same RNC as the source coverage area; (iii) if the target coverage area is not served by the same RNC as the source coverage area, delaying handoff until a current segment of the communication session is complete; and (iv) if the target coverage area is served by the same RNC, handing off the communication session to the target coverage area.
