    • A method and apparatus for preserving the sequential relationship of a plurality of data packets 310 generated by separate source devices 14 and ordered as a data stream 300, despite transmission over radio channels which introduce ordering errors comprises method steps and apparatus structure for identifying at a first terminal, data packets from within the data stream as a function of source, generating data packet sequence information for identified data packets, storing values corresponding to data packet sequence numbers as a function of source and transmitting data packets, source device identity and packet sequence information to a second terminal having first terminal source device and data packet sequence information. Upon receipt of a first terminal transmission, the second terminal retrieves from second terminal memory, first terminal data packet sequence information and compares the stored data packet sequence information with received data packet sequence information. As a function of the comparison, received data packets are forwarded to an appropriate application for further processing when sequence information sequence numbers compare and stored in an order determined by the sequence information when the sequence numbers do not compare.

    • A CM (105) receives requests for data transfer from a series of UMs (101-103) and from an EM (104). The requests contain the UM (101-103) or EM (104) address and the size of the data packet to be transferred. The CM (105) processes the requests on a FIFO basis, stores the requests in a queue and schedules either a small data channel (415) or a large data channel (420), depending on the packet size to be transferred, an acknowledgement channel (425) and also the corresponding number of required timeslots. The CM (105) picks the first request off the queue and sends a grant to the particular UM (101-103) or EM (104) which receive the grant and immediately access either the assigned small or large data channels (415, 420) in the required number of timeslots and the acknowledgement channel (425).
    • CM(105)从一系列UM(101-103)和EM(104)接收对数据传输的请求。 请求包含UM(101-103)或EM(104)地址和要传输的数据包的大小。 CM(105)以FIFO为基础处理请求,将请求存储在队列中,并根据要传送的分组大小调度小数据信道(415)或大数据信道(420),确认信道 (425)以及相应数量的所需时隙。 CM(105)从队列中选出第一请求,并向接收授权的特定UM(101-103)或EM(104)发送授权,并立即访问所分配的小数据或大数据信道(415,420) 在所需数量的时隙和确认信道(425)中。
