Abstract
Location management in cellular networks have been in focus for the research community for a number of years. The current static method of determining location or paging areas has been shown to be sub- optimal and costly for operators. Therefore, much research has been focussed on dynamic schemes, which show great promise in cost optimisation. However, the research has still been focussed on aggregation of user behaviour and location area determination based on the aggregate.
In this paper, we present another solution and argue that per-user behaviour based schemes will perform even better than the aggregate schemes. We present an analytically based proposal, which delegates the responsibility of performing individual updates to the terminals, making the scheme easy to deploy in current cellular systems. In addition, we simulate the relative cost savings obtained compared with the currently used static schemes. The results indicate that our proposed method can cut the cost of location management significantly and free up valuable spectrum for user data.
