Abstract :
A new way to manage users having different mobility characteristics (slow and fast users) in a two layer cellular system, through the use of the techniques of overlapping coverage and channel rearrangement, is provided. Overlapping coverage areas of nearby base stations arise in cellular communications systems, especially in small cell high-capacity microcellular configurations. With overlap, some users may have access to channels at more that one base station. This enhanced access can be used to improve the teletraffic performance characteristics. Channel rearrangements are used to benefit users who are in the range of only one base station. An analytical model for teletraffic performance is developed. Performance measures are derived and discussed
