Improvement of Sleep Operation for the Reduced Paging Delay on Cellular System

摘要

We propose a novel paging scheme with a variable paging interval for low power consumption and/or short paging delay. The proposed scheme is based on the fact that packet arrivals during a session follow the characteristics of self-similar process for Http service, while session arrival statistics can be modeled as the Poisson process. The adjustment of paging period provides a useful solution for efficient paging to the UE in the dormant state on packet-switched cellular networks, even though the paging performance is strongly dependent on the traffic arrival model.
