Abstract: A method, system and article of manufacture for exchanging data between an asynchronous network and a synchronous network is presented. Data is exchanged between the networks in a sequence of time frames which are partitioned into downlink, uplink and contention periods. These downlink, uplink and contention periods are further divided into time slots, each of which carries either data or control cells between the networks. Cells of data are allocated to the time slots according to their cell deadlines which are proportional to the transmission delay of the network connection over which the cells are to be carried. This cell allocation is then stored in a slot map and communicated to all nodes within the networks in order to facilitate the data transmission.

Abstract: A system is described which integrates terminal traffic in a digital voice cellular radio communication system. Data is conveyed from remote data stations and remote radio telephone stations over a reverse channel TDMA frame. The allocation of time slots in the reverse channel TDMA frame is controlled at the base station. The base station provides priority to radio telephones having digitized voice traffic. The base station assigns time slots within the reverse channel TDMA frame based upon allocation requests received from radio telephone stations and remote data stations. Remote data stations may contend on a random access for a minority of a set of time slots in the reverse channel data frame. Additionally, they may request an assigned slot by inserting an allocation request in a control slot of the reverse channel data frame. The base station allocates time slots on a voice radio telephone priority, and assigns any excess time slots to data stations waiting for access to the reverse channel.
