Abstract: During an initial part of a communication session, a transmitting node transmits digital data over a first air interface channel to a receiving node, using a first data rate and a first level of repetition. A degradation in quality of the communication session is detected. During a subsequent part of the communication session, the transmitting node transmits digital data over the first air interface channel as before but also transmits the digital data over a second air interface channel, using a second data rate and a second level of repetition. The second data rate is higher than the first data rate, and the second level of repetition is higher than the first level of repetition. Thus, during a given transmission period, the transmitting node may transmit a voice frame once over the first air interface channel and N times over the second air interface channel.

Abstract: Presently disclosed are systems and methods for wireless communication devices (WCDs) to share relevant performance-metric data with nearby devices having similar configurations. One embodiment takes the form of a method carried out by a WCD. The method includes receiving into a first WCD from a second WCD, via a direct wireless link between the WCDs, data indicating a configuration of the second WCD. The method also includes making a determination as to whether the configuration of the second WCD is at least threshold similar to the configuration of the first WCD and, if so, sharing with the second WCD, via the direct wireless link, performance-metric data for the wireless communication network.

Abstract: A method and system for dynamically allocating backhaul bearer service based on network loading conditions to help use backhaul-network resources more efficiently. A RAN detects an event relating to bearer service establishment for a given application. Then the RAN identifies a standard bearer service for the given application, where the standard bearer service has a first quality of service. After detecting the event, the RAN determines that a load of the backhaul communication network does not exceed a load threshold. Then, based on the determination that the load of the backhaul communication network does not exceed the load threshold, the RAN selects a bearer service for the given application, where the selected bearer service has a second quality of service that is higher than the first quality of service. Next, the RAN causes the selected bearer service to be established.

Abstract: A method and apparatus to help minimize tuneaway time of a user equipment device (UE), by dynamically scheduling when the UE should tune away to scan for coverage of a particular wireless communication system, such as a time division duplex (TDD) system for instance. The UE may receive downlink transmissions from a TDD system and determining a downlink transmission schedule of the TDD system based on when those downlink transmissions occurred. Further, the UE may then use the determined downlink transmission schedule as a basis to schedule tuneaway of the UE from a serving system to scan for coverage of the TDD system.

Abstract: A wireless communication device (WCD) may be configured to engage in a wireless data communication session of a given type. The WCD may determine the given type of wireless data communication session, and based on the given type, the WCD may set itself to operate in a current operational state selected from a group consisting of a first and second operational state. While engaged in the wireless data communication session, the WCD may wirelessly receive a voice call setup request from a radio access network (RAN) seeking to set up a voice call to the WCD over an air-interface protocol. In accordance with the current operational state, the WCD may make a decision of whether to accept or reject the voice call request so as to interrupt or not interrupt the wireless data communication session.

Abstract: Described are various approaches for considering inter-base-station link congestion levels in connection with handoff of a mobile station when the source base station (or another entity) is able to select a target base station for handoff from among a plurality of base stations. In one aspect, the plurality of base stations are each communicatively linked via a respective inter-base-station link with the source base station serving the mobile station. The source base station (or another entity) selects the target base station from among the plurality of base stations based at least in part on a congestion level of each base station's respective inter-base-station link. The source base station then hands off the mobile station to the target base station.

Abstract: A method, apparatus, and system for helping to manage advanced handoff to a coverage area based on correlation with a geographic region. A mobile station determines that it is in or approaching a defined geographic region, and the mobile station determines from correlation data that the geographic region is correlated with a particular cellular coverage area. The mobile station therefore requests handoff to the cellular coverage area and provides an advanced-handoff indication to cause the serving radio access network to maintain assignment of a radio connection in the coverage area longer than the network would normally, to help allow time for the mobile station to arrive at the coverage area and begin communicating on the radio connection with the network.

Abstract: In one aspect, an exemplary method involves a WCD: (i) determining a likelihood of roaming, wherein the likelihood of roaming indicates a likelihood that the WCD will be handed off from a preferred coverage area to a non-preferred coverage area; and (ii) using the likelihood of roaming as a basis for managing an active set of the WCD. In particular, the WCD may manage its active set by setting at least one active-set parameter affecting the number of active sectors in an active set of the WCD, and then maintaining its active set according to the setting of the at least one active-set parameter. According to an exemplary embodiment, a WCD will make an effort to increase the number of sectors in its active set when the likelihood of roaming is greater, and vice versa.

Abstract: A plurality of public safety answering points (PSAPs) are accessible via a voice-over-packet (VoP) network. A wireless access point of the VoP network is provisioned with a PSAP identifier and/or access point identifier to facilitate the routing of emergency services calls from the wireless access point to the appropriate PSAP. When a mobile node transmits a message to originate a call, the wireless access point parses the message to determine whether the mobile node is requesting an emergency services call. If an emergency call is being requested, the wireless access point inserts the PSAP identifier and/or access point identifier with which it has been provisioned into the message and forwards the modified message to a proxy server. The proxy server receives the modified message and routes the call to the appropriate PSAP, based on the PSAP identifier and/or access point identifier contained therein.

Abstract: A mobile node and its home system generate synchronized time-based codes at periodic time intervals. Each time-based code is valid for a predetermined time period. To facilitate anonymous operation when roaming, the mobile node identifies itself with a coded identifier instead of a public identifier. The coded identifier used at a given time includes the time-based code that is valid for that given time. To authenticate the mobile node, a serving system receives authentication information from the mobile node and forwards the authentication information to a home system. The authentication information includes the current time-based code and a timestamp. The home system identifies the mobile node from the current time-based code and the timestamp. The home system then uses the authentication information to authenticate the mobile node.
