In this study, a route-based group location registration (RGR) scheme is considered to reduce location registration and paging costs when there are many mobile stations (MSs) in a transportation system (TS) such as bus and train routes. In addition to adopting the existing group location tracking (GLT) scheme, the RGR scheme tries to minimize the total signaling cost by using the mobility characteristics of the TS whereby vehicles move along a specified route from the point of departure to the destination. In this study, we propose a 2-step paging (2SP) scheme based on an estimation of the location of the vehicles of a TS to reduce the paging cost of the RGR scheme. In this 2SP scheme, when an incoming call occurs, the first paging area is determined in accordance with an estimation of the location of the TS vehicle using the time from location registration to call occurrence. Since the moving speed of the TS vehicle is almost constant, the probability that the first paging will succeed is very high, which reduces the paging cost by roughly half. Numerical results show that the larger the route threshold K in the RGR scheme, the larger the reduction in total cost because of the 2SP effect. As a result, it can be seen that 2SP increases the optimal K, which minimizes the total cost compared with simultaneous paging. The results of this study can be used for mobility management research of mobile networks as well as for performance analysis of mobility management schemes.

An efficient location management plays an important role in mobile communication networks. In this study, a direction-based location registration (DIR) scheme and its modified scheme called a unidirection-based location registration (uniDIR), both of which adopt a line paging to reduce paging costs, are considered. The problems of the previous performance analysis method for DIR and uniDIR are pointed out, and a new accurate analysis model to properly analyze the correct performance is proposed. Using the new analysis method, the exact performance of DIR and uniDIR is obtained, and the performance comparison results of the two schemes are presented. According to the results of performance analyses in various environments, this study confirms that DIR has better performance than uniDIR in most cases despite the reduction in paging cost.
