Modeling of anchor radio system handoff

An early version of the Bellcorepersonal access communications systems (PACS) specified a method of providing inter-radio system (RS) handoff assuming an ISDN/AIN switching system. To support switching systems without ISDN/AIN capabilities, an alternative approach calledanchor RS handoff has been proposed for PACS. Two possible anchor RS approaches areswitch loopback anddirect connect. This paper studies the performance of the two anchor RS methods. We show that if users exhibit locality of movement, the switch loopback method is better. Otherwise, the direct connect method should be considered.
