Polling deregistration for unlicensed PCS

Abstract

This paper describes a polling deregistration protocol for a wireless access communications network which would support interoperability between licensed personal communications services (PCS) and unlicensed-PCS (UPCS), We show how the protocol can be efficiently implemented in the personal access communications system (PACS) for licensed PCS and in the PACS-Unlicensed Version B (PACS-UB), An analytical model is proposed to analyze the performance of the polling protocol, A cost function is derived, which can be used to estimate the optimal polling frequency.
