“…Recently, there are some ongoing standards and research work on designing MAP protocol for inter-system roaming. In [14], a signaling protocol is proposed to provide inter-system roaming to personal handyphone system (PHS) users. Under this scheme, service data function units and service control function units are utilized to provide the roaming numbers to the MTs when they request location registration.…”

An efficient signaling protocol for mobility application part (MAP) is essential to mobility support when mobile terminals roam between different networks in next generation wireless systems such as IMT-2000. In this paper, a new signaling protocol is proposed to reduce the overhead caused by mobility management, alleviating network load and consumption of network resources. Moreover, the new protocol effectively reduces the latency of call delivery and call loss rate due to crossing wireless systems with different standards and signaling protocols. Instead of performing location registration after a mobile user arrives at the new system, the mobile user is required to update its location information prior to its reaching the boundary of two systems. Results in this study demonstrate that the new protocol yields significant benefits in terms of reducing signaling costs, delays, and call loss rates.

“…To study this effect, we show the comparison of call losses with different as a function of intersystem roaming probabilities in Fig. 10, which are obtained from (13) and (14). We assume that the incoming or outgoing calls would be lost if an MT cannot finish its intersystem location registration.…”

In next-generation wireless systems, one of the major features that is different from the current personal communication service systems is the seamless global roaming. The mobile subscribers will be allowed to move freely across different networks while maintaining their quality of service for a variety of applications. To meet this demand, the signaling protocol of mobility management must be designed, supporting location registration and call delivery for roaming users who move beyond their home network. In this paper, a new signaling protocol is proposed, emphasizing the active location registration for ongoing services during the mobile subscribers' movement. Another important goal of this new protocol is to reduce the overhead caused by mobility management so that the signaling traffic load and consumption of network resources can be reduced. The new protocol efficiently reduces the latency of call delivery and call loss rate due to crossing wireless systems with different standards or signaling protocols. The numerical results reveal that the proposed protocol is effective in improving the overall system performance.
