  • Patent number: 7643423
    Abstract: Dynamic allocation of communication channels among communication units (CU) in a communications system. Dynamic channel allocation employs a reservation set for reserving channels and an allocation set corresponding to the reservation set for receiving allocated channels. The reservation set and the allocation set are changed dynamically as a function of network parameters to control the dynamic channel operation. Reservation set information is broadcast downlink to multiple users to reserve an allocation set of uplink radio resources for specific ones of the users. The system uses a modification of the packet data channel (PDCH) of a GPRS/EGPRS or EDGE system which employs an Uplink Status Flag (USF) on each PDCH downlink radio block. The downlink reservation set information is commonly received by all users in the group of users. Allocation delay, bandwidth efficiency and other system parameters are optimized.

  • Patent number: 6212387
    Abstract: The present invention is a communication system having a plurality of forward channel communications and a plurality of corresponding reverse channel communications in a region for communications with cellular users. Each region includes a plurality of zone managers. Each zone manager includes a broadcaster having a broadcaster transmitter for broadcasting a plurality of forward channel communications using broadband broadcaster signals to form a plurality of broadcaster forward channels. Each zone manager includes an aggregator for processing reverse channel communications. Each zone manager communicates with a collector group for receiving reverse channel communications from users and forwarding reverse channel communications to the aggregator. Each of the users includes a user receiver for receiving a different forward channel from said broadcaster and includes user transmitter means for broadcasting user reverse channel communications in a different user reverse channel.
