    摘要: A novel method and apparatus provides an efficient means for delivering data to multiple wireless destinations by the issuing of a negative acknowledge message from a receiving terminal upon detecting a second outstanding block error. The transmitting terminal sends an error correction block for all the blocks up to but not including the block with the second detected error, which increases the throughput. Each receiver is independent of the other receivers and decodes the incoming blocks. Every receiver performs the error detection function on every received block and detects whether or not the block has been received correctly.

    摘要: A method enables a subscriber unit (20) to access a common communication system to communicate with a selected communication system. The subscriber unit receives (404) an indication of any communication systems available in a geographic region associated with the common communication system and requests access to the selected communication system. After receiving (506) an enabling program for the selected communication system, the subscriber unit transfers (508) the enabling program to an external processing device. A novel subscriber unit (20) and external processing device (24) are also described.

    摘要: A common communications system (119) provides information regarding the availability of other local communication systems (111-117) within the common communications system coverage area to a generic, programmable subscriber unit (120). Geographical location information is then supplied to the common communications system (119) indicating position of the subscriber unit (120). The geographic information is used by either the common communication system (119) or subscriber unit (120) to provide information pertinent only to one or more local communications systems (111-117) that the subscriber unit (120) may select. The common communication system (119) or the subscriber unit (120) can also be used to selectively filter or extract information such that the information presented to the user is related to the geographical location. The subscriber unit (120) then selects one of the local communications systems (111-117) and receives enabling programming from that local communication system. The enabling programming permits the subscriber unit (120) to configure itself to operate on the selected communication system.
