摘要： What is disclosed is a method of operating a communication system. The communication system includes wireless access nodes and a network control system, where user devices and the wireless access nodes communicate over wireless links, and the wireless access nodes and the network control system communicate over individually associated backhaul links. The method includes transferring forward communications in a forward direction from the network control system to a first one of the wireless access nodes over a forward link portion of a first backhaul link associated with the first wireless access node, and transferring reverse communications in a reverse direction from the first wireless access node to the network control system over a reverse link portion of the first backhaul link. The method also includes monitoring forward performance of the forward link portion and monitoring reverse performance of the reverse link portion, and identifying a second of the wireless access nodes to assist the first wireless access node. If the forward performance of the forward link portion exceeds a forward threshold, then the method includes instructing the first wireless access node to initiate a backup wireless link between the first wireless access node and the second wireless access node, and if the reverse performance of the reverse link portion exceeds a reverse threshold, then the method includes instructing the second wireless access node to initiate the backup wireless link between the first wireless access node and the second wireless access node. The method also includes using the backup wireless link to offload communications of the first backhaul link.

摘要： During connection establishment, an access network and/or an access terminal may decide whether to transmit bearer-traffic data rather than null-traffic data based on a channel quality of a wireless link. For example, if the access network has forward bearer-traffic data ready for transmission to the access terminal during connection establishment, the access network may decide to transmit that forward bearer-traffic data rather than forward null-traffic data in response to determining that a forward-channel quality of the wireless link is sufficient to carry such data. As another example, if the access terminal has reverse bearer-traffic data ready for transmission to the access network during connection establishment, the access terminal may decide to transmit that reverse bearer-traffic data rather than reverse null-traffic data in response to determining that a reverse-channel quality of the wireless link is sufficient to carry such data.

摘要： A method and corresponding system for controlling billing for communication service. An area of coverage of a first wireless serving system is dynamically determined based on signals from one or more mobile stations served by the first wireless serving system. A determination is then made as to whether a mobile station was within the determined area of coverage of the first wireless serving system when the mobile station was being served with communication service by a second wireless serving system. And a billing rate, for billing for the communication service, is selected based at least in part on the determination.

摘要： Systems, methods, and computer-readable media are provided for reducing the use of network resources during a conference call with mobile communications devices. An active conference call is detected between a conference bridge service, including a conference bridge leader, and participants who are ace sing the conference call by way of a mobile communications device in a wireless communications network. An indication is received that the conference bridge leader has muted the lines of the participants. As a result, each of these mobile communications devices are notified to stop transmitting data over a reverse link other than data used for signaling purposes until the devices are no longer muted.

摘要： Disclosed is a method and apparatus for helping to reduce latency that may arise from requesting retransmission of non-received packets. A device carrying out the method may be arranged to not send negative acknowledgements for non-received packets. Further, in an implementation where the device is to send for each packet of an incoming sequence either a positive acknowledgement indicating that the device received the packet or a negative acknowledgement indicating that the device did not receive the packet (and constituting a request for retransmission of the packet), the device will send for each packet a positive acknowledgement regardless of whether the device received the packet. The device will thus send a positive acknowledgement for at least one packet even though the device did not receive the packet.

摘要： A mobile station requests origination of a call and reports signal strength measurements of pilot signals from multiple sectors, where some of the sectors support a preferred air interface configuration (such as RC 11) and some do not. The signal strength measurements may be evaluated to determine which sectors to use for the call and whether to use RC 11 or a default air interface configuration (such as RC 3 or RC 4) for the call. Sectors that support the preferred air interface configuration may be evaluated using a first threshold, and sectors that do not support the preferred air interface configuration may be evaluated using a second threshold. The first threshold can be greater than the second threshold, in order to favor the use of sectors that support the preferred air interface configuration over sectors that do not.
