Abstract: Systems and methods are provided for automatic PLMN serving system reselection based on E911 PSAP termination failures. For example, a UE may initiate a call for emergency services on a network provided by a cell site simulator. When the connection fails, metrics corresponding to the termination failure are communicated to the PLMN the next time the UE connects to a legitimate network. The fraudulent cell sites may be communicated by the UE to other UEs via peer-to-peer communication and/or added to an FPLMN list to prevent other UEs from connecting to networks provided by the fraudulent cell sites.

Abstract: According to aspects herein, methods and systems for event-driver user-based primary device selection are provided. The method begins with receiving an indication of an imminent UE failure event from at least one UE, wherein the UE is a member of at least one primary device selection cluster. The primary device selection manager then identifies at least one replacement primary device to take over for the at least one UE wherein the at least one replacement primary device is a member of the at least one primary device selection cluster. A notification containing a selection of potential replacement primary devices is transmitted to the at least one UE. A user may select at least one replacement primary device from the selection in the notification and transmit that selection to the primary device selection manager.

Abstract: A method and system for enabling MMS message delivery to a recipient device. An MMSC receives and stores MMS message content to be delivered to the recipient device, and the MMSC responsively sends to the recipient device an MMS-notification message carrying an address of the MMS message content stored at the MMSC and then receives a reply indicating that the recipient device received the MMS-notification message. The MMSC then detects that, after the MMSC received the reply, (i) at least a predefined threshold amount of time has passed and (ii) the MMSC has not yet received from the recipient device a request to download the MMS message content. And responsive to at least the detecting, the MMSC then sends to the recipient device a data-service-trigger message that triggers turning on data service of the recipient device, thus enabling MMS-message delivery to the recipient device.

Abstract: A method for correcting connectivity failures of core applications on a user equipment (UE) is disclosed. The method comprises a client detecting a plurality of request-reply message sequences between a core application and a corresponding server, and learning a set of request-reply message sequences within the plurality of request-reply message sequences that are not producing a connection error with the corresponding server. The method further includes creating a series of ghost replies that each mimic a reply that is one of the set of learned replies coming from the corresponding server and not producing a connection error, and then retaining the series of ghost replies. The method then includes detecting at least one connection error between the core application and the corresponding server, and feeding a ghost reply to the core application.

Abstract: Disclosed are a method, apparatus, and system for authenticating a communication session between a user equipment device (UE) and a communication network. A first authentication of a UE is performed by generating an authentication key, transmitting the authentication key over a first communication link from the UE to a communication network, authenticating the UE using the authentication key, and generating an authentication result indicative of authenticating the UE. A second authentication of the UE is performed to authorize a communication session over a second communication link between the UE and the communication network. The second authentication includes transmitting UE identifying information over the second communication link from the UE to the communication network and authenticating the UE using the UE identifying information and the authentication key. The second communication link is established under an internet protocol.

Abstract: Examples disclosed herein include methods, systems, and devices to help a UE to securely output a copy of a security key stored on the UE. According to examples, a UE receives a test security key from a provider. Based on the received test security key, the UE computes a test result, and then the UE transmits the computed test result to a network authentication system. The UE receives from the network authentication system a response indicating a match between the computed test result and a test result computed by the network authentication system. Based on the received response indicating the match, the UE outputs a copy of the security key stored in the UE to the provider.

Abstract: When a wireless communication device (WCD) is served by a first base station and not by a distant second base station, the WCD may initially be receiving strong pilot strength from the first base station and weak pilot strength from the second base station. Due to the WCD moving into a position where the first base station coverage is obstructed, however, the WCD may detect a quick drop in first base station pilot strength without a corresponding proportional increase in the second base station pilot strength, to the point that the second base station pilot signal is sufficiently stronger than first base station pilot signal that the WCD hands over to the second base station. In response to detecting that scenario, the WCD may report that the location of coverage of the second base station is an uncertain representation of the WCD's location, to help ensure reliable location-based service.

Abstract: Disclosed are methods and systems for using mobile-station-specific gateway-burden data for assigning mobile stations to data-access gateways. One embodiment takes the form of a method carried out by at least one network entity in a communication system that includes a radio access network (RAN) for providing wireless service to mobile stations and that further includes multiple data-access gateways. The method includes maintaining mobile-station-specific gateway-burden data that associates each of multiple mobile stations with one or more indicia of the extent to which those mobile stations have respectively consumed one or more resources of one or more of the data-access gateways.

Abstract: A first communication device receives a communication from a second communication device. The communication could be part of the signaling used to establish a call to the second communication device or an audio signal that the second communication device conveys after its user has answered the call and started speaking. Based on the communication from the second communication device, the first communication device provides a user-discernible indication regarding the environment in which the second communication device is being used, such as an indication that the second communication device is being used with a speakerphone. If the second communication device is being used in a vehicle, the first communication device may also provide a user-discernible indication regarding the operational status of the vehicle, such as whether the vehicle is in motion and/or the number of occupants in the vehicle.

Abstract: Disclosed is a method and system to help manage wireless service in a scenario where a UE is served by a first RAN and begins being served by a second RAN. In accordance with the disclosure, a determination may then be made of whether the UE will likely engage in at least a threshold extent of scanning for coverage of the first RAN while the UE is being served by the second RAN. If the determination is affirmative, the UE may then be caused to not scan for coverage of the first RAN while the UE is being served by the second RAN. Whereas, if the determination is negative, the UE may be allowed to scan for coverage of the first RAN while the UE is being served by the second RAN.

Abstract: Disclosed herein are methods and systems for enforcing prepayment based on lack of support of authentication functionality by a particular wireless serving system. In one embodiment, at least one home-core-network entity associated with a home core network of a mobile station receives from a particular wireless serving system a registration request associated with the mobile station. Responsive to receiving the registration request, the at least one home-core-network entity makes a determination as to whether the particular wireless serving system supports authentication functionality. Responsive to the determination being that the particular wireless serving system does not support authentication functionality, the at least one home-core-network entity sends to the particular wireless serving system a registration response that grants the request subject to at least one prepayment requirement.

Abstract: A method and corresponding system for managing how long a UE will wait before attempting to be served by a RAN, such as before the UE searches for coverage of the RAN and determines whether the RAN supports providing a particular service. The method may apply in a scenario where the RAN is normally configured to provide the particular service but from time to time may lack support for providing that service. As disclosed, a network entity may evaluate past instances of the RAN lacking support for providing the service, and may thereby estimate a typical (e.g., average) duration for such lack of support. Based on that estimate, the network entity may then provide the UE with an indication of how long the UE should wait before the UE attempts to be served by the RAN, and the UE may responsively wait for that time period.

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 selecting a coverage area in which a given mobile station should operate. The system will receive user ratings of call quality per coverage area. The system will then use the received user ratings as a basis to select a coverage area in which the given mobile station should operate. The system will then cause the given mobile station to operate in the selected coverage area. By using these user ratings as a basis to select a coverage area in which the given mobile station should operate, the system can help improve call quality overall for users, thus increasing user satisfaction with wireless performance.

Abstract: A wireless communication device (WCD) may receive a communication from an initiating party. The communication may be associated with a communication application, and may include a communication-application identifier that identifies the initiating party. The WCD may check whether a contacts list for the WCD contains user name data associated in the contacts list with the communication-application identifier. Upon determining that the contacts list does not contain such user name data, the WCD may querying a network server (NS) to request user name data associated with the communication-application identifier, receive from the NS a reply containing particular name data associated with the communication-application identifier along with additional communication-application user identifiers, each of which is also associated with the particular name data.
