SHOEWU, L.A AKINYEMI Department of Electronic and Computer Engineering, Lagos State University, Epe Campus, Epe, Nigeria. engrshoewu@yahoo.com, letua034@yahoo.com ABSTRACT There is a need for future communication networks to adapt to the increasing mobile users. A number of mobility management schemes are introduced in this discourse. There are varying definitions of mobility management depending on the problem in question. In this paper use is made of a framework that shows how the different definitions of the mobility management relate to each in future communications network. More so, discussion on how some existing management solution map into the new framework shall be discussed. Keyword: Mobility Management, Communication Networks, Mobility Paradigms, mobile Internet, Protocol Layers INTRODUCTION There has been more of less separated track of mobility management research. The first one emerged from the need to make telephone services mobile and another from the need to make internet services mobile. In the area of fixed telephony and physically big computers, it was feasible to use devices near the user’s current location than carry the device with the user. While the telephony and Internet research communities have developed solutions for both personal and device mobility different services a lot of technologies and technology have been introduced due to a different nature of the fields there seems to be some mismatches in the terminology use. Nowadays the all IP networks (Acharya, et al, 1997) are bringing telephony and internet tightly together and solutions from internet and telephony community are used to complement each others also in mobility management. Hence, it is essential to agree on terminology and framework, which allows discussion on and categorization of different technical solutions in sensible manner. In this paper, we shall propose such a framework and associated terminology. LITERATURE REVIEW In the integrated personal mobility architecture (IPMoA) work in literature (Thai and Seneviratne, 2001) have described breakdown of user mobility. More so personal mobility i.e. movement of the user across terminal devices is spilt into personal communications and personalizing operating environment and the latter into link, network and session layer mobility. The table below shows the highlight of various mobility. Table 1 Application – Layer Mobility Mobility explicitly supported by the application itself Continuous Mobility User’s are able to access communication service also while moving Device Mobility Movement of the terminal device within network Link Layer Mobility Mobility is supported by link layer technology device’s point of attachment to IP network do not change Localized Mobility Optimized solution for local movement avoids global impacts from movement Macro Mobility Solution that provides global network wide mobility Network Layer Mobility Mobility is supported by network layer technology e.g. mobile IP Nomadic Mobility User’s are able to access communication services in specific areas e.g. office, home and airport Personal communications Provide communication services and ubiquitous reach ability for user irrespective of the devices she is currently using Personal Mobility Movement of the user across terminal devices Personalizing Operating Environments Personalizing and maintaining personalization of the operating environment when changing device Session Layer Mobility Mobility is supported in session layer the sessions are maintained transparently to the applications State Mobility No movement included only for the ache for completeness
