Performance methods for mobility management in cellular networks

This paper presents performance methods for mobility management in cellular networks. A queueing analysis is first undertaken, in which the system is modelled as an open Jackson network, consisting of M M/M/1 queues. Given environmental parameters, the corresponding probability matrix is obtained, and hence the traffic matrix equations. From these equations, the traffic load in each cell is evaluated. Secondly, a BONeS DESIGNER simulation model is created and applied to the evaluation of mobility processing load. One case study has been made on Cellular Digital Packet Data (CDPD) networks. The results from both analysis and simulation are similar. It is important to note that the proposed traffic analysis approach may also be used for evaluating and analysing other signalling traffic in cellular networks.
