ABSTRACT:
A method of allocating access to a shared media network, with specific application to tracking and paging mobile users of a cellular telephone network. Each cell of the network broadcasts a load factor .alpha., representative of the load on the cell's control channel. Each user in a cell determines a registration priority for itself, and also a registration threshold based on .alpha.. In the preferred embodiment of the present invention, each user is assigned a base threshold time T, and each user in a cell computes a registration threshold time T', based on T and .alpha., and registers its location with the network if the last such registration was longer ago than T'. Users are paged only in cells to which they could have traveled since their most recent location updates.
