A queuing priority channel access protocol for voice/data integration on the air interface of microcellular mobile radio networks

摘要

A new concept is proposed for a dynamic length microcellular structure that has the potential to provide a communication link to all mobile users roaming in the service area. The implications of the system as well as its practical implementation are also addressed. Then, a queuing priority channel access protocol is presented for handling voice and data traffic by the network. As the interruption of a conversation is unbearable, the protocol aims at minimising this phenomenon. Data traffic, on the other hand, is served on a delay basis as its prompt delivery is not stringent. A traffic methodology is developed for an accurate teletraffic modelling of the network based on the evidently finite number of users roaming in a microcell. The effect of a hostile radio channel on data transmission is considered. The highway microcellular mobile radio network is considered as a case study. However, the analysis is fairly general to other microcellular scenarios.
