  • Patent number: 9065739
    Abstract: An approach is provided for supporting end-to-end Quality of Service (QoS) control. A QoS profile identifier is generated that maps to a QoS parameter. The identifier is transmitted over the radio communication system to an end station, wherein the end station determines the QoS parameter based on the received identifier. The approach also provides an alert mechanism in which the end station transmits an alert message upon detecting a deviation from the QoS parameter.

  • Patent number: 8929316
    Abstract: A process and system for controlling selection of which MS is to receive the next packet data transmission on a forward channel and selection of which plural MCS is to be used for the packet data transmissions on the forward channel. A process for controlling selection of MCS method to be used by a BTS to transmit data packets over a forward shared channel to a MS stores information at the BTS, the information containing MCS methods which may be selected to transmit data packets over the forward shared channel to the MS; receiving from the MS at the BTS a quality indication of transmission of data packets over the forward channel to the MS; and selecting a MCS method from a plurality of MCS methods which may be used to transmit data packets on the forward channel dependent upon the received quality indication.

  • Patent number: 8817637
    Abstract: Apparatus, and an associated method, that reduces the occurrence of generation of redundant requests for retransmission of packet-formatted data, formatted at a physical layer and at a higher-logical layer, such as at an RLP layer. An estimate of an appropriate delay period is formed. The estimate is responsive to communication conditions in the communication system. When a data packet appears to have been inadequately delivered to the RLP logical layer, a DELAY_DETECTION_WINDOW timer is caused to time out the delay period estimated by the estimator. The request for retransmission, generated at the RLP layer, is permitted, upon expiration of the timer if the data packet has not yet been successfully delivered to the RLP layer and the transmitter has not given up the data packet delivery.

  • Patent number: 7995470
    Abstract: Apparatus, and an associated method, for utilizing traffic classes in a CDMA2000, or other packet radio, communication system. Traffic class designations are identified and used pursuant to communication set-up procedures. Depending upon the class identified in the request, allocations of communication resources are made. A traffic class signal generator generates values that identify a requested traffic class, and a formatter formats the traffic class into a message, such as a QoS BLOB that is used to allocate communication resources.

  • Patent number: 7936664
    Abstract: A method is provided for facilitating efficient usage of radio capacity in a radio communication system including a communication station operable to receive, over a plurality of subchannels of the radio communication system. In this regard, the packet-formatted data has an overall sequence, and is divided into a plurality of portions receivable by the communication station over respective subchannels, where each portion has a respective link sequence. The method includes detecting missing packet-formatted data at the communication station based upon the overall sequence or at least one of the link sequences. Then, when the missing packet-formatted data is detected based upon the overall sequence, a time period is timed, and when the communication station fails to receive the missing packet-formatted data before the step of timing times out, retransmission of the missing packet-formatted data is requested.

  • Patent number: 7903610
    Abstract: A method for providing a reverse link handoff mechanism includes, with respect to communication between a mobile station and a first cell, initiating a start of a cell switch delay by transmitting a request that a new data channel be established with a second cell. The method further includes communicating with the first cell during the cell switch delay and upon an end of the cell switch delay, switching data transmission to the second cell. The cell switch delay is a time interval extending from a time that the request is transmitted until startig of reception of data packets via the new data channel by the second cell. The application of the cell switch delay is determined based on a location of the first cell and the second cell.

  • Patent number: 7835315
    Abstract: An approach is provided for addressing in a multiple carrier communication system. In one embodiment, a group index is assigned to a group of terminals of a communication network. The group index permits sharing of addressing indices supported by the communication network for transmission of data to the group of terminals. In another embodiment, a plurality of terminals is classified using preamble indices corresponding to the terminals into one or more classes. A multi-user packet, which utilizes the preamble indices to activate only a class of the terminals for processing the multi-user packet, is generated.

  • Patent number: 7684366
    Abstract: Apparatus, and an associated method, for reporting QoS information associated with a reverse link communication service effectuated in a radio communication system, such as a CDMA2000 cellular communication system. The mobile station includes a service quality level selector that selects a selected service quality level, such as a communication rate, at which the communication service is to be effectuated. The mobile station further selectably includes a message generator that generates a service quality indication message. A detector detects the scheduling architecture of a network part of the communication system with which the mobile station communicates. And, information contained in the message generated by the message generator is dependent, in part, upon the scheduling architecture.
