In personal communications applications, users communicate via wireless with a wireline net- work. The wireline network tracks the current location of the user, and can therefore route mes- sages to a user regardless of the user's location. In addition to its impact on signaling within the wireline network, mobility tracking requires the expenditure of wireless resources as well, includ- ing the power consumption of the portable units carried by the users and the radio bandwidth used for registration and paging. Ideally, the mobility tracking scheme used for each user should depend on the user's call and mobility pattern, so that the standard approach, in which all cells in a registration area are paged when a call arrives, may be wasteful of wireless resources. In order to conserve these resources, the network must have the capability to page selectively within a registration area, and the user must announce his or her location more frequently. In this paper, we propose and analyze a simple model that captures this additional flexibility. Dynamic pro- gramming is used to determine an optimal announcing strategy for each user. Numerical results for a simple one-dimensional mobility model show that the optimal scheme may provide significant savings when compared to the standard approach even when the latter is optimized by suitably choosing the registration area size on a per-user basis. Ongoing research includes com- puting numerical results for more complicated mobility models and determining how existing system designs might be modifiedto incorporate our approach. |
