“…The overall costs of maintaining accurate location records are at present only poorly understood. However, recent work indicates that simply for telephone traffic, the excess network signaling load expense would be much larger than that required for classical fixed traffic [5][6][7][8][9][10]. If migrant programs and databases are included, the aggregate signaling load can only be greater.…”

It is difficult to compare various mobility management schemes since as yet there exist no absolute bounds on optimum performance which can be applied to any procedure regardless of assumptions about mobility, network structure, and the like. It would be useful to fill this gap by developing some general theory, which optimally would precisely relate quantities of interest such as minimum average effort/delay in determining unit locations and minimum average location information dissemination rate over the network in fundamental terms. We therefore note that in order to quantitatively evaluate the average cost of any mobility management scheme, timevarying probability distributions on mobile unit location are required. These distributions might be derived from specific motion models, approximated via empirical data [18, 33], or

“…1(a)] is expected to grow rapidly due to increased service demands for existing services (e.g., 800 number service, alternate billing service), and the introduction of new services such as PCS and video dial tone. The current SS7 signaling network may not be adequate to support the stringent delay requirements imposed by broadband and PCS services [2]- [5]. For future network architectures in which ATM is used for the backbone, it has been considered that it may be cost-effective and efficient to integrate signaling traffic with the user data traffic on the same physical network.…”

Abstract-Current cellular subscribers have a geographic phone number (e.g., in AMPS and U.S. digital cellular systems) or a number which contains the network provider's identity (e.g., in GSM), and whenever subscribers register or receive (and possibly, originate) a call, a home location register (HLR) database has to be queried. The wired infrastructure supports a function called global title translation (GTT) that converts the subscriber's number to an HLR database address. A special feature of next generation wireless access service will be to support personal communication services (PCS's) and wireless subscribers with portable personal numbers, or nongeographic phone numbers (NGPN's), that do not indicate the service provider or HLR database serving the user. In addition, the GTT function may not be available when the wired backbone is an ATM network. Thus a key function required in future wireless access systems with wired ATM backbones will be the ability to translate an NGPN to the identity of the HLR which serves the subscriber, a process we call NGPN translation. (Note that the same functionality is also needed for subscribers with local, portable phone numbers.) We discuss the requirements of NGPN translation and some alternative schemes. We propose two schemes for fast, efficient, scalable and flexible NGPN translation which use ideas of dynamic hashing, caching, and indirection. The schemes use a hash function in the visiting location registers (VLR's) (or serving SCP) and a set of distributed translation servers which store the NGPN-to-HLR mapping. We discuss how the operations required to maintain the translation information can be performed. Finally, we perform a simplified analysis of the scalability of the alternative schemes as well as the hash-based schemes we propose.
