Abstract: 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.

Abstract: System and methods for generating and transmitting dynamic route-update-radius parameters are described. The parameters are dynamic in that the parameters may be modified from time-to-time. Modification of the parameters may be triggered by a radio access network (RAN) determining that a coverage area formed by the RAN is handling more than a threshold amount of communications to and/or from access terminals operating in the coverage area. The RAN may transmit the dynamic route-update-radius parameters so as to prevent some access terminals from registering with the coverage area while the coverage area is handling more than the threshold amount of communications. While the coverage area is handling a reduced amount of communications, such as less than a threshold amount of communications, the access network may transmit default route-update-radius parameters to coverage areas remote from that coverage area. The route-update-radius parameters may include a route-update-radius, a modified route-update-radius, and a route-update-radius offset.

Abstract: Methods and computer-readable media are provided to determine which sector the mobile device will bias during soft handoff. Signals are received from multiple sectors, and for a first quantity of time slots of a frame, the signals are inspected to determine whether a quality threshold is met. Based on whether the quality threshold is met, each sector is assigned a power control command indicating that either a decrease or increase of output power is recommended when a subsequent signal is sent to the mobile device. For a second quantity of time slots, the overall power control command sent to the sectors corresponds to the power control command assigned to the sector that has communicated the highest quality signals for the first quantity of time slots of the frame.

Abstract: Wireless access terminals operating in a radio access network (RAN) may move from one coverage area to another coverage area formed by base stations within the RAN. The RAN tracks the location of the access terminals so that RAN can efficiently route communications, such as page messages, to a base station serving the access terminals. From time-to-time, the access terminals can send route-update messages to inform the RAN of their locations. Sending the route-update messages can increase the loading on base station channels that carry the messages. Methods, systems, and devices for delaying transmission of the route-update messages are described. Delaying or not delaying transmission of the route-update messages may be dependent on occupancy of access channels of a base station and whether the access terminals are mobile at the time the route-update messages are to be sent.

Abstract: Systems, computer-readable storage media, and methods are disclosed for providing wireless voice communication transmissions between a mobile unit and at least one base station. An illustrative method may comprise receiving an access request from a mobile unit. Based on information extracted form the access request and protocols for selecting a communication channel, identifying a selected communication channel for transmissions between the mobile unit and the base station. In the event of congestion or poor RF quality on the selected communication channel, where multiple communication channels associated with a home network are available at a base station, the mobile unit will attempt to access an alternate communication channel before going to a roaming network.

Abstract: What is disclosed is a wireless access system. The wireless access system includes a wireless access control system configured to maintain an available pool of Media Access Control Identifiers (MAC IDs) for subsequent use by a base station, remove a portion of the MAC IDs from the available pool, and use the portion of the MAC IDs for wireless communications between a wireless transceiver of the base station and a plurality of user devices. The wireless access control system is configured to determine that the available pool of the MAC IDs is insufficient, and in response, select a set of the user devices based on at least wireless signal strength. The wireless transceiver of the base station is configured to instruct the selected set of the user devices to not use the base station for the wireless communication, and in response, the wireless access control system is configured to return ones of the MAC IDs used by the selected set of the user devices to the available pool.

Abstract: Disclosed herein are methods that enable a sending entity and a receiving entity, operating in a wireless communication network, to adjust transmission power at the sending entity according to one of two power control modes. One method provides for a continuous power control mode in which the sending entity begins transmission of a particular data flow at a power level responsive to a most recently received power adjustment command. Another method provides for a per-flow power control mode in which the sending entity begins transmission of a particular data flow at a power level responsive to the most recent transmission power level of the different particular data flow. Further methods provide for the receiving entity to dynamically instruct the sending entity in which power control mode to operate.
