A Predictive Paging Scheme for IMT-2000 Systems
نویسنده
چکیده
Paging is a process to locate mobile terminals in wireless systems, which is initiated by the users calling from a fired or mobile environment. In particular, paging issue in IMT-2000 systems is very important to maintain the wireless services to the mobile subscribers who are allowed to roam in different systems instead of stand-alone systems. In this paper, we introduce a predictive paging scheme based on the concept of boundary location registel: We develop the corresponding signaling messages to describe the call delivery procedure of intersystem roaming. Since paging costs are associated with bandwidth utilization ana' delays infuence call setup time, they are used as metrics in evaluating the performance of the proposed paging scheme. -

An optimal partition algorithm for minimization of paging costs
A novel paging scheme under delay bounds is proposed for personal communication systems. This paging scheme is independent of the location probability distributions of the mobile users and satisfies the delay bounds, while minimizing the amount of bandwidth used for locating a mobile user. The proposed paging scheme includes the optimal partition algorithm and paging procedure with respect to p...
متن کاملLocation Registration and Paging in Mobile Satellite Systems
Mobile satellite systems are a crucial component of the future global telecommunications infrastructure. An important aspect of the future system is to manage the location of both users and satellites. This paper presents a strategy for location registration (update) and paging in Low Earth Orbit (LEO) mobile satellite systems. First, we discuss the tradeoff that exists between four proposed sa...
متن کاملRobust Model Predictive Control for a Class of Discrete Nonlinear systems
This paper presents a robust model predictive control scheme for a class of discrete-time nonlinear systems subject to state and input constraints. Each subsystem is composed of a nominal LTI part and an additive uncertain non-linear time-varying function which satisfies a quadratic constraint. Using the dual-mode MPC stability theory, a sufficient condition is constructed for synthesizing the ...
متن کاملDynamic Location Management Scheme Using Agent in a Ubiquitous IP-Based Network
IP-based IMT Network Platform(IP) is an ubiquitous platform supporting mobility using two step IP address mode converting – IP host address(IPha) and IP routing address(IPra) – in a backbone network. Mobile Node(MN) in IP maintains its state as either active or dormant state, which is transferred to active state through Paging process when communication is required. In this paper, we proposed a...
متن کاملPower injection of renewable energy sources using modified model predictive control
This paper presents a simple model predictive control (MPC) approach to control the power injection system (PIS) for renewable energy applications. A DC voltage source and a single-phase inverter that is connected to the grid by an LCL filter form the PIS. Grid voltage is considered a disturbance for the system. For eliminating this disturbance, a modified model is proposed. It is usual to ...
