Abstract: A method and system that uses user-equipment (UE) capability reporting to control UE service. A UE provides its serving base station with an initial capabilities report indicating that the UE does not support determining and reporting when neighboring coverage is threshold strong, and so the base station does not yet provision the UE with a measurement event including a threshold to facilitate such determining and reporting. When the UE then determines that its serving coverage is threshold weak, the UE then transmits to its serving base station an updated capabilities report indicating that the UE does support such determining and reporting, and so the base station then provisions the UE with threshold (e.g., provisions the UE with a measurement event causing the UE to compare measured neighbor coverage strength with such a threshold).

Abstract: Methods and systems are disclosed that support the aggregation of acknowledgement messages and control messages. Advantageously, acknowledgement and negative acknowledgement indications for multiple client nodes are combined into a single aggregated message which is broadcast or multicast to the multiple client nodes. Based on unique identifiers assigned to each client node, client nodes are grouped such that the aggregated acknowledgement messages can be efficiently encoded to conserve both network capacity when they are transmitted, as well as processing capacity when they are parsed by the client nodes. If code division multiple access (CDMA) technology is used, the aggregated acknowledgment message can be transmitted without CDMA spreading to effectively broadcast or multicast it to multiple client nodes. A similar technique can be employed for the efficient broadcast or multicast of aggregated control messages.

Abstract: A wireless communication device (WCD) stores a location of a portable WAP and is configured to report the stored location of the portable WAP to a location-based service provider (LBSP) when the WCD is within coverage of the portable WAP and requests a location-based service from the LBSP. While the WCD is within coverage of the portable WAP, the WCD (i) uses a wireless-communication interface to detect that the WCD is also within one or more particular cellular coverage areas and (ii) stores a correlation between the portable WAP and the one or more particular cellular coverage areas. Thereafter, while the WCD is again within coverage of the portable WAP, the WCD determines that the WCD is not within coverage of the one or more particular cellular coverage areas. In response, the WCD reconfigures itself to not report the stored location of the portable WAP to the LBSP when the WCD requests the location-based service.

Abstract: According to aspects of the disclosure, a method and system are provided for managing cell selection in a wireless communication network. In accordance with this disclosure, each cell in a radio access network (RAN) broadcasts a respective carrier-aggregation policy of the cell on its air interface. A UE engaging in a cell selection process reads the respective carrier-aggregation policy of each cell under consideration and selects a cell on which to attach based at least in part on the respective carrier-aggregation policies of the cells. The UE can then attach to the selected cell so that the selected cell can then serve the UE.

Abstract: A method and corresponding system to help facilitate the application of service policy rules for client devices while reducing the amount of signaling between network entities is disclosed. In accordance with one example, the wireless network may evaluate the extent to which the service policy rules defined by the UE's service profile have been applied by the wireless network. Based on this evaluating, the network may identify a subset of service policy rules that have been applied to greater than a threshold extent by the network for the given UE. And in response to this identifying, the network may cause the PDP to provision the PEP, with the subset of service policy rules, rather than provision the PEP with every possible service policy rule. As a result, the PDP and PEP may refrain from engaging in excess signaling, and the wireless network, in turn, may enjoy reduced congestion.

Abstract: A method and system for managing uplink control channel communication by adjacent base stations. Adjacent base stations may programmatically work with each other to arrange for their respective use of different sub-carriers for scheduling their respective uplink control channel communications. Further, to help make more efficient use of all available sub-carriers, a given base station may schedule uplink traffic channel communication for one or more user equipment devices on the same sub-carriers that a neighboring base station is using for uplink control channel communication if those one or more user equipment devices do not report detecting the neighboring base station above a threshold level.

Abstract: A method for controlling a UE situated in both a coverage area of a first base station and a coverage area of a second base station involves detecting that the UE is ping-ponging between being served by the first base station and being served by the second base station and determining that the second base station is a relay base station. Further, the method involves, responsive to detecting the ping-ponging and determining that the second base station is a relay base station, (a) determining a carrier on which the first base station provides service and on which the second base station does not provide service, and (b) based on the first base station providing service on the determined carrier and the second base station not providing service on the determined carrier, causing the UE to be served by the first base station on the determined carrier.

Abstract: An improved method for controlling how long a device will occupy a wireless channel, based on consideration of QoS class of communication on the channel. With respect to a communication that the device detects on the channel, the device could determine QoS class by detecting a sequence of energy levels in association with the detected communication, the sequence of energy levels indicating the QoS class. The disclosed method could be applied by a cellular base station to control how long the base station will provide cellular service on the channel, where the channel is also used for other communications such as WiFi communications for instance.

Abstract: A method for dynamically selecting one of a plurality of base stations for provision of timing information. A base station compares satellite signal strengths measured at satellite-positioning-system receivers of a plurality of base stations, such as the plurality of base stations in a local area network (LAN) for instance. The base station then selects one of the plurality of base stations to provide timing information based at least in part on the comparison, such as the one base station having the greatest satellite signal strength for instance. The base station then operates according to timing information indicated by satellite data from the selected base station. Advantageously, this method can help to increase the accuracy and reliability of the timing information.

Abstract: A method and system to help manage reference-signal transmission power. A base station's reference-signal transmission power will be adjusted based on consideration of the coverage quality of one or more WCDs that are located at or near a mid-point between the base station and an adjacent other base station. In particular, if a threshold extent of coverage quality reports for the base station's reference signal received at or near the mid-point are threshold low, then the serving base station could responsively increment its reference-signal transmission power and/or responsively cause the adjacent base station to decrement its reference-signal transmission power. Whereas, if a threshold extent of such coverage quality reports are threshold high, then the serving base station could responsively decrement its reference-signal transmission power and/or responsively cause the adjacent base station to increment its reference signal transmission power.
