A protocol for cellular radio signaling channels carrying data and high-priority accessing requests

In cellular radio, accessing requests are transmitted through signaling channels in the form of minipackets. The accessing requests are generated by a variety of mobile users that impose different constraints. The authors consider data and high-priority public-safety cellular users and isolate a single channel that is shared by the mixed user population. They devise and analyze a mixed protocol that satisfies the constraints of the high-priority public-safety users, while maintaining the data traffic with satisfactory delays. For the high-priority users, a well-defined and finite but bursty population and a number of different priorities are considered. The population of data users is assumed time-varying and not well-defined, and is modeled as limit Poisson and in the analysis of the protocol
