Title: METHOD AND APPARATUS FOR PROVIDING INFORMATION TO A PLURALITY OF COMMUNICATION UNITS IN A WIRELESS COMMUNICATION SYSTEM
Abstract:
A wireless communication system (100) employs a method and apparatus for providing information to multiple communication units (121-129). The communication system includes a communication infrastructure (101, 102, 103, 105, 111-113, 120), a data network (107) and an information source (109). The multiple communication units each subscribe to an information service provided by the information source. The communication infrastructure creates a subscription group that includes the multiple communication units. The infrastructure receives subscriber information including at least one information unit from the information source and sets up a point-to-multipoint group call with the subscription group. The infrastructure then transmits the subscriber information to the multiple communication units. Any information unit not confirmed by the multiple communication units is re-transmitted by the infrastructure. If any information unit remains unconfirmed after the re-transmission, the infrastructure sets up a point-to-point communication session with individual communication units and re-transmits the remaining unconfirmed information unit.
