Satellite mobile communications always require LOS environments. If the LOS path is obstructed, the signal strength can be much lower than the SNR threshold for normal communication, so a coming call will not reach the user. In this case, an enhanced paging is needed to tell the user to move out of the shadow to receive the call. In this paper, a enhanced paging design is proposed for LTE-based...

IP paging aims to reduce power drain and signaling overhead of dormant mobile hosts and so to enhance the scalability of the mobile Internet. Previous IP paging schemes do not, however, scale well adhering to the static location update algorithm. This static approach accompanies signaling and computation overhead even with the costly optimization of the paging area. Excluding the shortcomings o...

In this paper, we consider the use of our recently proposed Intra-Domain Mobility Management Protocol (IDMP) in generation (4G) mobile networks. On evaluating the heterogeneous access technologies, cellular layouts and application characteristics of 4G environments, we realize a need to reduce both the handoff latency and the frequency of mobility-related signaling. We first present IDMP’s fast...

The paging signaling overhead is occurred in Paging extensions for Mobile IP(P-MIP) which was proposed to reduce registration signaling overhead of Mobile IP(MIP). And quick paging IP scheme using residence pattern of mobile user(QP-MIP) is proposed to overcome the above inefficiency. To the exact analysis of QP-MIP and P-MIP, the Mobile Node(MN) state transition behavior is modeled and the ste...

STUDY OBJECTIVES To determine whether the type of paging system causes significant differences in the response time by physicians to their pages in an ICU setting. DESIGN AND SETTING Prospective cohort study performed in the ICU of two university-affiliated hospitals. All pages were classified by several different variables, including the type of paging system: direct paging if a nurse or hos...

future increase of mobile communication subscribers will require a great capacity expansion of the cellular systems. in order to accommodate the increasing number of subscribers, the cell size will have to be much smaller than current size. therefore, it is predictable that the location updating and paging procedures will produce a major part of signaling traffic in these networks. this pape...

In this paper, we consider the use of the recently proposed Intra-Domain Mobility Management Protocol (IDMP) in and generation (3/4G) wireless cellular networks to reduce the latency of intradomain location updates and the mobility signaling traffic. We first present enhancements to basic IDMP that provide fast intra-domain handoffs by using a duration-limited, proactive packet ‘multicasting’ s...

Subscriber satisfaction and maximum radio resource utilization are the pivotal criteria in communication system design. In multi-Carrier CDMA system, different paging algorithms are used for locating user within the shortest possible time and best possible utilization of radio resources. Different paging algorithms underscored different techniques based on the different purposes. However, low s...

Traditional paging models seek algorithms that maximize their performance while using the maximum amount of cache resources available. However, in many applications this resource is shared or its usage involves a cost. In this work we introduce the Minimum Cache Usage problem, which is an extension to the classic paging problem that accounts for the efficient use of cache resources by paging al...

The process of nding a unit in a mobile communications system is called paging and requires the use of limited network resources. Although it is understood how to minimize the use of network resources and satisfy delay constraints when paging a single unit, optimal policies for paging multiple units are diicult to derive. Here we adapt single unit polling methods to obtain simple ensemble polli...
