摘要： In a system having a base station transmitter for transmitting data blocks to one or more mobile stations over a radio link, a method for determining a transmit power level at which to transmit a current block. A quality measurement is received from a mobile station indicating an average radio link quality over a previous group of blocks, wherein not all of the blocks of the previous group of blocks were necessarily transmitted at the same transmit power level. A transmit power attenuation level is determined for the current block based on the quality measurement. The transmit power attenuation level is subtracted from the initial transmit power level to determine the transmit power level for the current block.

摘要： A method of controlling link transmission parameters of a communication flow in a network caches one or more network parameters at the end of a first communication flow for an elapsed time, and adjusts the network parameters for controlling link quality and transmit power of a next communication flow based on an uncertainty that is caused by caching for the elapsed time. The state of a communication channel during a previous communication flow (connection) is used to determine network parameters to use at a future communication flow. When a connection begins, and the network does not know the ideal settings to use, the network defines a specified, elapsed time duration over which the state of a previous connection no longer can be trusted, i.e., an uncertainty period. Network parameters are adjusted to account for uncertainty caused by the elapsed time.

摘要： In a system having a base station transmitter for transmitting data blocks to one or more mobile stations over a radio link, there is a method for determining an uplink transmit power level at which to transmit a current data block over a radio link from the mobile to the base transmitter station. The method evaluates airlink quality measurements in the radio link over a measurement interval, wherein each time a message is sent to the mobile station, it is evaluated whether a specified number of uplink blocks have transmitted by the mobile station since the start of the measurement interval. Based on the evaluated airlink quality measurement, the method determines the uplink transmit power level that the mobile should be using for the current block, and adjusts the transmit power level, if necessary, for the current block.

摘要： Rather than transmitting a large full Broadcast-Multicast Services (BCMC) Parameters Message (BSPM) containing a full set of BSPM parameters pertaining to all active BCMC flows within a sector on an infrequent basis, smaller-sized differential or partial BSPMs are instead transmitted. Differential BSPMs contain updated information for existing flows or information for new flows, and because of their smaller size, can be transmitted more frequently than full BSPMs. A mobile terminal receiving a differential BSPM updates the flows with the information contained within the differential BSPM or adds the information contained within the differential BSPM for a new flow. Partial BSPMs divide the flow information contained in a large full BSPM over a plurality of smaller-sized partial BSPMs, which are separately and sequentially transmitted at different times. A mobile terminal receiving these partial BSPMs then reconstructs the full BSPM from a collection of received partial BSPMs.

摘要： In a method of tracking a user in a communication network supporting a broadcast-multicast service, the network classifies groups of users into tracking areas. Movement of a user may be tracked as the user crosses a boundary between two tracking areas in the network. The method may enable a balance to be achieved between use of uplink overhead and the level or granularity of tracking desired, so as to conserve radio resources.

摘要： A method of triggering registration of a mobile station in a network supporting broadcast multicast services employs registration triggers based on flow conditions and frequency conditions. For example, a registration message may be generated based on a change in frequency, from a first frequency to a second frequency, that is monitored by the mobile station. If the second frequency is not known to the network based on flow identifier information previously registered by the mobile station with the network, a registration to the network is triggered. By sending a registration, the network may page a mobile station on a single, given frequency, since the registration message indicates the mobile station's presence on that given frequency.
