This paper presents an analysis of the Anchor Radio System (RS) handover method for Personal Access Communications System (PACS). This handover method provides a simple yet effective solution without adding new requirements to the existing network infrastructures. Based on this technique, inter-RS and interswitch handovers can be achieved using a new RS-to-RS interface called Inter-RS Interface (IRI). This paper first describes the use of the IRI Protocol among PACS based RSs. Then it proposes an analytical model for theAnchor RS handover method to determine the expected handover delay under given mobility, call duration and signaling delay parameters.
