Abstract: Apparatus and method for enabling a single communication system (100) to support at least two communication services. For example, one can support both cellular telephone services and trunked dispatch services by sharing some, but not all, of the system infrastructure. Access control gateways (201) and base stations (203) comprise common infrastructure elements, while two separate processors provide control for each service, these being a communication agent processor (104) to support telephone services, and a dispatch call processor (106) to support dispatch call services. These two independent processors each include a data base (303 and 307) that includes information concerning communication units (204-206) operating within the system. During a call set-up sequence, the access control gateway (201) receives a call request from a communication unit via a base station, and passes the request to the appropriate processor, which uses its corresponding database to support the requested service.

Abstract: A data communications system (Figure 1) is described in which variable length messages (Figures 3, 4 and 5) are communicated between a general communications controller (GCC 104) and a plurality of portable and mobile radios (130, 132, 134, 136, 138). The variable length messages (Figure 3) include a bit synchronization field (204), a message synchronization field (205) and a plurality of channel data blocks (203) for efficiently and reliably handling long strings of data or text. Each channel data block (Figure 5) includes an information field (503), a parity field (505) for error-connecting the information field and a channel state field (507) indicating whether or not the radio channel is busy or free. The GCC (104) is coupled to a cellular arrangement of channel communications modules (CCM's 106, 108, 110, 112), which each include a radio transmitter (114, 120, 124) and/or radio receiver (116, 118, 122, 126, 128). The mobile and portable radios (130, 132, 134, 136, 138) communicate with the GCC (104) by way of the CCM's (106, 108, 110, 112).

Abstract: Two channel data blocks include an information field, with control data and a check word, and a parity field coded from the information field according to a predetermined code. The field bits are interleaved so that the consecutive bits of a field are separated by a predetermined number of bits. Following data blocks include information and parity fields with the bits interleaved. The last blocks information field also includes a check word coded from the data in the information field of the third and following blocks. In another arrangement the first block includes an information field, with at least one command and a station address, and a parity field coded from the information field according to a predetermined code. The second block has an information field including a block count indicating the number of following blocks, a message sequence number incremented for each message and a check word, and a parity field. Following blocks have an information field and a parity field. The bits of the fields in each block are interleaved.
