This paper discusses the agent based mobility management functionality developed by the ACTS-340MARINE project. MARINE’s mobility management procedures are based on mobile agent and distributed processing technology. The MARINE service, Broadband Video Telephony, is introduced as a scenario for the MARINE mobility management procedures. Three approaches for User Assistant agents to support user...

As the number of Mobile IP users grows, so will the signalling overhead associated with Internet mobility management in the core IP network. This presents a significant challenge to Mobile IP as the number of mobile devices scale-up. In cellular networks, registration and paging techniques are used to minimize the signalling overhead and optimize the mobility management performance. Currently, ...

When a universal personal telecommunications (UPT) user visits a mobile network, both terminal mobility and personal mobility are involved and it may take a long time for UPT call delivery to the UPT user because it is required to retrieve both the terminal mobility related data in mobile network and the UPT user related data in UPT database. If the UPT database also manages location and status...

abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...

Terminal mobility(TM) and personal mobility (PM) should work together to provide mobility to mobile users in fixed and mobile networks. TM supports movement between different areas with in the same region. In mobility management, an MT (Mobile Terminal) updates its location when it changes its location and all calls are delivered to the MT by paging all cells within that registered location are...

Many strategies have been proposed to reduce the mobility management cost in mobile communication networks. This paper studies the zone-based registration methods that have been adopted by most mobile communication networks. We focus on two special zone-based registration methods, called two-zone registration (2Z) and two-zone registration with implicit registration by outgoing calls (2Zi). We ...

some researches made in the field of agency problem issue, deal with the role of control systems regarding owners and managers. in this research the relationship between the two control mechanisms, namely the voluntary disclosure (external control mechanism) and outside directors (internal control mechanism), which are reductive of agency problems, has been studied. for this reason, a sample ...

Registration/deregistration with a mobility database called Visitor Location Registers (VLRs) is required in a PCS network when a mobile phone moves between registration areas. Several schemes were proposed to deregister a mobile phone after it moves out of a registration area. A simple scheme, called implicit deregistration, is studied in this paper, which does not specifically deregister any ...

We propose and analyse a proxy-based regional registration scheme for integrated mobility and service management with the goal to minimize the network signaling and packet delivery cost in Mobile Internet Protocol (MIP) systems. Under the proposed proxy-based regional registration scheme, a client-side proxy is created on a per-user basis to serve as a gateway between a mobile node (MN) and all...

Location management is an essential service in mobile networks. It provides mechanisms for recording and querying location of mobile units in the network. This is needed for establishing calls to mobile units. In PCS networks, location management protocols such as IS-41 and GSM use statically defined Registration Areas (RAs) with two-level hierarchy of location databases. In this paper, we prop...
