    摘要： A method is provided for controlling delivery of packets over a synchronous control channel in a wireless system employing the High Rate Packet Data (HRPD) standard. The synchronous channel is comprised of a plurality of slots, and a first packet is sent over the synchronous control channel in a first one of the plurality of slots along with an indication of a second one of the plurality of slots in which a second packet will be delivered. Thereafter, the second packet is sent over the control channel in the second one of the plurality of slots. Subsequent packets are handled similarly.

    摘要： A method is provided for sending messages to a plurality of access terminals in a wireless network. The method comprises broadcasting a multicast message along with a predetermined address associated with the plurality of access terminals. The multicast message and the address associated with a plurality of access terminals is received at an access terminal. The access terminal compares the received address with a locally stored address, and the message is accepted in response to the received and locally stored addresses being the same. If the received and locally stored addresses are different, then the multicast message is discarded.

    摘要： The number of Reverse Activity Bits (RABs) equal to '1' per frame is a Congestion Overload (CO) metric used to determine whether the reverse link in a wireless communications system is in a congestion overload state due to a reverse link RF overload. When the value of the CO metric exceeds a first predetermined threshold that is indicative of a congestion overload condition, the system enters a block state where all new connection requests are blocked. Once in the block state, if the value of the CO metric does not decrease but continues to increase and exceeds a second higher threshold, the system enters a mute state. In the mute state a predetermined large percentage of existing active calls are muted. Specifically, a message is sent downlink to specific Ats instructing them to reduce their transmission rates to zero but to still maintain their active connections.

    摘要： The present invention provides a method of providing a group paging message. One embodiment of the method includes providing a first message during a first portion of a predetermined time period. The first message includes information indicating a second portion of the predetermined time period during which at least one idle first mobile unit is to wake up and attempt to receive a second message from the base station(s). The embodiment of the method also includes providing a third message during a third portion of the predetermined time period. The third message includes information indicating the second portion of the predetermined time period during which at least one idle second mobile unit is to wake up and attempt to receive the second message. The third portion of the predetermined time period is different than the first portion.

    摘要： A method and an apparatus for maintaining a quality of service (QoS) for a multi-media packet data service in a transport network is provided. The method comprises determining a first packet loss indication for a first flow of QoS traffic packets. The method further comprises determining a second packet loss indication for a second flow of QoS traffic packets, wherein the determination of the first packet loss indication for the first flow of QoS traffic packets is independent from the determination of the second packet loss indication for the second flow of QoS traffic packets. The method further comprises determining whether to drop the first flow of QoS traffic packets based on the first packet loss indication or to drop the second flow of QoS traffic packets based on the second packet loss indication. By using per- flow independent packet loss statistics to determine whether that flow should be dropped and gradually dropping such QoS flows having the most impact on a desired QoS performance, a reduced number of QoS flows may be dropped to recover a data transport network from congestion.

    摘要： A method and an apparatus for reducing packet loss for a packet data service during congestion in a transport network are provided. The method comprises measuring a packet loss rate over a time period in one or more flows of data traffic packets associated with the packet data service to determine whether the one or more flows of data traffic packets are experiencing a variation in a desired traffic performance level at a particular time duration during the congestion in the time period. The method further comprises triggering a request to reduce a flow rate of at least one of the one or more flows of data traffic packets based on the packet loss rate if the at least one of the one or more flows of data traffic packets experiences the variation in the desired traffic performance level. By using a distributed transport congestion control, for example, only such Best Effort data traffic packet flows that generate bursty traffic at a specific moment of congestion sense the congestion and thus trigger an associated rate reduction action. However, other flows that do not experience the congestion may not be affected.
