Abstract: In an example method, a base station determines that a UE is CSFB capable and that the base station is currently serving a relay on a first carrier of a plurality of carriers. The base station provides a coverage area on which to serve UEs, and the coverage area operates on the plurality of carriers. Based on at least the determining that the UE is CSFB capable and that the base station is currently serving the relay on the first carrier, the base station assigns the UE to operate on a carrier of the plurality of carriers other than the first carrier rather than having the UE operate on the first carrier on which the base station is currently serving the relay.

Abstract: Systems and methods are described for allocating resources from an access node in a wireless network. Power reports may be received from multiple wireless devices at the access node. Based on the received power reports, the access node may classify each wireless device of the multiple wireless devices as a high power wireless device or a low power wireless device. An offset scheduling factor may be selected for wireless devices classified as high power wireless devices at the access node. Resources can be allocated for high power wireless devices using the selected offset scheduling factor.

Abstract: A method and system for paging of a wireless client device (WCD). When a wireless communication system encounters a trigger to page a WCD, the system will identify the WCD's most recent serving base station (e.g., the WCD's currently registered base station, or the base station providing the WCD's currently registered coverage area) and will determine whether that base station is a relay base station or rather a non-relay base station. If the base station is a non-relay base station, then the system will provide the initial page of the WCD via just that base station (e.g., as in the zone based paging process discussed above). Whereas, if the base station is a relay base station, then the system will provide the initial (ordinal first) page of the WCD via both that base station and the donor base station that provides the relay base station's wireless backhaul connection.

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: Disclosed is a method and system for release of a UE's context record in response to failure of air interface communication. As disclosed, a wireless communication system includes a base station that has a protocol stack defining a series of logical processing layers through which the base station sequentially processes data for transmission to a UE. The layers include an upper layer and a physical layer at which the base station processes the data for communication over an air interface to the UE. Accordingly, the base station detects failure of air interface communication between the base station and the UE. In response to detecting the failure, and without waiting to detect at the upper layer a further failure corresponding with the failure of the air interface communication, the base station transmits to a network controller a UE-context release request requesting release of bearer context that was established for the UE.

Abstract: Disclosed is a method and corresponding apparatus to make use of hybrid-ARQ repetition factors as a way to differentiate service quality to various mobile terminals. Depending on a mobile terminal's subscription service class, such as the mobile terminal's PLMN, the mobile terminal may be made to use a particular hybrid-ARQ repetition factor. For instance, a mobile terminal of a high service class may be made to use a low hybrid-ARQ repetition factor, which may help the mobile terminal experience less downlink transmission delay and thus a higher downlink data rate. Whereas, a mobile terminal of a low service class may be made to use a high hybrid-ARQ repetition factor, which may cause the mobile terminal to experience more downlink transmission delay and thus a lower downlink data rate, and may further free up downlink transmission resources to facilitate better service for other mobile terminals.

Abstract: In systems and methods of maintaining a network connection of a wireless device, network connection information is associated with the wireless device and is maintained at a gateway node in communication with a first communication network and a second communication network. A first network connection between the wireless device and the first communication network is terminated, and a second network connection is established between the wireless device and the second communication network using the network connection information, wherein the association of the network connection information and the wireless device is maintained until the second network connection is established.

Abstract: Methods and systems are provided for using DRCLocks for conducting call admission control. In an embodiment, an access node provides service to a plurality of access terminals on a carrier in a coverage area, where the plurality of access terminals does not include a first access terminal. The access node receives a request for new service on the carrier in the coverage area from the first access terminal over an air interface, and responsively determines whether an aggregate-DRCLock condition is met. If the aggregate-DRCLock condition is met, the access node denies the request for new service.

Abstract: A radio access network (RAN) allocates a resource, such as a forward traffic channel, to a mobile station that is engaged in a call. During the call, the RAN monitors a reverse link signal that is received from the mobile station. If the RAN detects a reception failure, such as the receipt of an errored frame in the reverse link signal, the RAN determines the power level that the mobile station used to transmit the reverse link signal when the reception failure occurred. If the mobile station was already transmitting at its maximum power level, the RAN may immediately release the resource. Otherwise, the RAN defines a test period that is sufficient for the mobile station to increase its transmit power to the maximum level. If the reception failure continues throughout the test period, the RAN may then release the resource.

Abstract: Methods and systems are provided for using packet-transport metrics for setting DRCLocks. In an embodiment, an access node provides packet-data service to access terminals, which comprises (a) providing wireless service over an air interface in a wireless coverage area and (b) providing transport service over a packet-data network. The access node measures, over at least the packet-data network, each packet-transport metric in a set of one or more packet-transport metrics. The access node sets a DRCLock for at least one of the access terminals based at least in part on the one or more measured packet-transport metrics.

Abstract: A method and apparatus for managing page-response intervals. When a network entity receives a paging trigger signal, the entity determines a page-response interval to use for paging the mobile station, based on one or more factors such as (i) whether the communication is to be provided to the mobile station over the same air interface and/or same air interface protocol that will carry the paging to the mobile station and/or (ii) what network, interface, or other entity the trigger signal comes from and/or what network communication module receives the trigger signal. The network entity then uses the determined page-response interval when paging the mobile station, waiting that determined period of time after each page attempt before attempting to page again or before concluding that the paging effort failed.

Abstract: A method and apparatus to help mitigate interference from an adjacent coverage area. A user equipment device (UE) determines a time division duplex (TDD) frame arrangement of a neighboring base station and reports the determined TDD frame arrangement to a serving base station. The serving base station uses the reported TDD frame arrangement of the neighboring base station as a basis to avoid scheduling downlink transmission of bearer traffic to the UE at times when the TDD frame arrangement of the neighboring base station defines uplink transmission.

Abstract: When a roaming wireless communication device seeks to originate a communication, the device may originate the communication in a roaming system because the device has not yet run a next scheduled scan for a more preferred, home, system. In the disclosed method, the device may evaluate a current distance from where the device was located when it successfully communicated to a home system and may further evaluate a current duration from that successful communication. If the distance is threshold short and perhaps further if the duration is threshold short, then the device may originate the communication in the home system without having detected the home system through a scheduled rescan. Further, to help expedite origination, the device may set its origination power at the power that it used for the last successful communication.

Abstract: A mobile station measures a pseudonoise (PN) offset and a signal strength of a spread spectrum signal transmitted by a given sector of a spread spectrum communication system. The measured PN offset differs from a nominal PN offset of the given sector. The mobile station transmits a measurement message that includes the measured PN offset and the measured signal strength. The spread spectrum communication system receives the measurement message and determines a location associated with the mobile station (e.g., based on location coordinates included in the measurement message). The spread spectrum communication system determines the nominal PN offset of the given sector based on the measured PN offset and the location associated with the mobile station. If the given sector is a valid handoff destination, the spread spectrum communication system transmits to the mobile station a handoff instruction that identifies the given sector by the measured PN offset.

Abstract: A wireless network allocates uplink resources to wireless communication devices (WCDs) based on power headroom reports, with more resources being allocated to WCDs reporting greater power headrooms. Each WCD may determine a respective power headroom as a difference between its maximum transmit power and a transmit power requirement for its current uplink resource allocation. However, a WCD may report an adjusted power headroom that is obtained, for example, by decreasing its respective power headroom by an adjustment value. The WCD may then receive an uplink resource allocation that is based on the adjusted power headroom that it reported. The adjustment value could be based on a priority level of the WCD, a priority level of data to be transmitted by the WCD, and/or an instruction from the wireless network. In one example, basic-priority WCDs report adjusted power headrooms so that more uplink resources are available for high-priority WCDs.

Abstract: Disclosed herein are methods and systems that may help to determine and/or adjust parameters for zone-based paging over CDMA paging channels, based on the prevalence of devices that are configured for enhanced circuit switch fallback (eCSFB) in one or more paging zones. For example, a switch in a radio access network (RAN) may: (a) determine a respective measure of CSFB-device prevalence in one or more paging zones in the RAN, (b) use the respectively determined measure of CSFB-device prevalence in at least one of the paging zones as a basis to determine one or more parameters for zone-based paging in the at least one of the paging zones, and (c) apply the one or more determined parameters for zone-based paging in the at least one of the paging zones.

Abstract: Disclosed herein are methods and systems that may help to adjust, e.g., CDMA paging and access parameters in a coverage area, based on the prevalence of devices that are configured for enhanced circuit switch fallback (eCSFB) in the coverage area.
