t This paper gives a comparative description of two scenarios for location management in a mobile telecommunications system. The first scenario uses fixed location and paging areas. Mobiles perform a location update as they enter a new location area. The second scenario uses a time-out based location updating scheme. Mobiles start their timer as they leave the paging area they are currently reg...

Group paging can simultaneously activate hundreds of user equipments (UEs) using a single paging message. Upon receiving the group paging message, all UEs should immediately transmit their paging response messages through the random access channels (RACHs). Simultaneous channel access from a huge group of UEs may result in severe collisions of the RACHs during a very short period of time. In th...

In general, location track...

Modern non-volatile memory storage devices operate significantly faster than traditional rotating disk media. Disk paging, though never intended for use as an active memory displacement scheme, may be viable as a cost-efficient cache between main memory and sufficiently fast secondary storage. However, existing benchmarks are not designed to accurately measure the microsecond-level latencies at...

We evaluate the performance of IP paging with power save mechanism by formulating an analytical model and carrying out simulation study of Integrated IP Paging Protocol (IIPP) that integrates both the paging and power save functionality in IP layer. The results show that, compared to the Mobile IP regional registration, the IIPP significantly reduces the average power consumption of a mobile no...

This paper is a survey of competitive analysis of paging. We present proofs showing tight bounds for the competitive ratio achievable by any deterministic or randomized online algorithm. We then go on to discuss variations and reenements of the competitive ratio and the insights they give into the paging problem. Finally, we variations to the online paging problem to which competitive analysis ...

INTRODUCTION Automated paging systems that inform providers about abnormal laboratory values may alter their behavior. METHODS We prospectively studied provider behavior before and after implementation of a laboratory paging system that utilizes a filtering mechanism. RESULTS The proportion of laboratory results that were acted upon did not change significantly. However, providers were more...

In real-time systems, demand paging has not been used since worst case performance analysis technique for demand paging is not available. In this paper, we propose a technique to obtain the worst case bound on the demand paging costs and devise a worst case response time analysis framework considering the demand paging costs. We divide the technique into two different methods, DP-Pessimistic an...
