Abstract

The authors present the performance evaluation of a demand assignment multiple access (DAMA) scheme designed specifically for the mobile radio service (MRS) to be supported by the emerging mobile satellite systems (MSSs). MRS caters mainly to private voice dispatch applications, where traffic is characterized by short holding time and fixed connectivity. The DAMA scheme makes use of call queuing, batch processing, and pipelined signaling to minimize call setup overhead for MRS traffic. Batching delay and channel assignment delay are investigated by simulation modeling of many private dispatch networks operating over a multiple spot beam satellite. Traffic engineering issues are considered. A dynamic channel allocation scheme is devised to increase system capacity by sharing the DAMA channel pool between MRS and the mobile telephone service (MTS)
