  • Patent number: 9693239
    Abstract: Unsynchronized internal clocks of user equipments in a cellular communication system are addressed by a mechanism relying on a standalone clock function in user equipments. A network node distributes a time reference to a user equipment (UE), and the UE, using an internal clock function, time-stamps the logged measurements and/or events relative to the received time reference. When the UE has logged measurements, the UE indicates to the network node that it has an available measurement log. The network node may then request several UEs to deliver their respective measurement logs. The network node is then able to retrieve time-stamped measurement information from the measurement log of each UE relative to the sent time reference. The network node is then able to compare measurement information from each UE in a cell provided at the same time interval in all UEs.

    Abstract: Methods, systems, and portable devices capable of adaptive synthetic positioning while in a dead zone are described. In one method, when a portable device having a Global Navigational Satellite System (GNSS) receiver and a dead zone database enters a dead zone, it determines whether the dead zone database has a record for the dead zone. If it does, it retrieves parameters corresponding to the dead zone from the database and calculates synthetic position solutions using the retrieved parameters while in the dead zone. The portable device may also use the synthetic position solutions to help calculate position solutions when exiting the dead zone. If a dead zone database record does not exist, the portable device determines parameters for calculating synthetic position solutions in the dead zone and a new dead zone database record indicating a set of parameters based on the determined set of parameters is created.

  • Patent number: 9622193
    Abstract: The present invention concerns a method and system for reducing co-channel interference due to the deployment of N femtocells in a macrocellular network. Said method comprises a step (1) of taking power measurements on signals sent over this network, a step (3) of optimizing the transmission powers of the femtocells according to these measurements, and a step (4) of allocating to each femtocell its transmission power. Said method is characterized in that: during step (1) of taking measurements, the power measurements are only made by the N femtocells and these measurements are ordered temporally by a central facility UC in the system, during the optimization step (3), the transmission powers of the femtocells are maximized under the constraint of maintaining a minimum quality of service of terminals that would be attached to the base stations in the macrocellular network.

  • Patent number: 9614950
    Abstract: An application is automatically launched in response to identifying a specific user in the vehicle. Upon launching the application, a historical calling profile is automatically downloaded for the user. The historical calling profile includes individual vehicle call records. The historical calling profile is updated with vehicle call record(s) corresponding to each instance of an outgoing call placed while the user is in the vehicle. A probability of a telephone number being chosen for an outgoing call, within time increments while the user is in the vehicle or in response to a request, is dynamically determined. The probability is dependent upon location data points retrieved from the individual vehicle call records. A list of telephone numbers sorted by the probability is dynamically generated. A most recently generated list of telephone numbers sorted by the probability is caused to be displayed on a vehicle display while the user is in the vehicle.

  • Patent number: 9609104
    Abstract: An intermediate server communicatively coupled to a mobile phone associated with a first phone number corresponding to a first contact type and a second phone number corresponding to a second contact type, receives a request to receive an incoming call associated with a caller phone number. The request corresponds to the first or second phone number. The intermediate server identifies a contact type associated with the request and a contact type associated with the caller based on the caller phone number. The intermediate server further determines whether the caller is misclassified by comparing the contact type associated with the request and the contact type associated with the caller. In addition, the intermediate server sends a notification indicating that the caller is misclassified to the mobile phone in response to determining the contact type associated with the request and the contact type associated with the caller do not match.

  • Patent number: 9609507
    Abstract: A method of supporting enhanced SIM replacement procedure is proposed. A UE detects that a first identification module running a first application is inserted. The first identification module belongs to a PLMN, and an enhanced service is provided by an operator of the PLMN via a second application. The UE sends a notification to the operator for obtaining a second identification module. The UE detects that the second identification module running the second application is inserted. The UE sends a second notification to the operator for activating the second identification module such that the UE is able to use the enhanced service provided by the operator. The device-assisted solution for SIM replacement complies with existing security/authentication model, has no standard charge, and complies with existing SIM replacement model and offers a simpler and more automatic procedure.

  • Patent number: 9602377
    Abstract: Embodiments calculate an estimated latency between computing devices. A latency service aggregates latency records defining latency measurements and corresponding latency factors from a plurality of computing devices. From the aggregated latency records, the latency service defines relationships between the latency measurements and the corresponding latency factors. Responsive to a request for an estimated latency from a mobile computing device, the latency service applies the defined relationships to estimate the latency based on the latency factors associated with the received request. In some embodiments, the estimated latency includes three portions: a first latency value representing the latency from the mobile computing device to a cell site, a second latency value representing the latency from the cell site to an access point, and a third latency value representing the latency from the access point to a destination computing device.

    Abstract: A method and apparatus related to a first radio network node serving a first UE in a first mobile radio network for enabling a D2D communication with a second UE served by a second radio network node in a second radio network. The first radio network node establishes a connection with the second radio network node. The first UE (230) requests to the first radio network node to enable a communication with the second user equipment (290). The first radio network sends a first message comprising information related to the first UE (230) to the second radio network node (280) for configuration of the second UE (290). The first radio network node receives a second message for configuration of the first UE (230) and sends to the first UE (230) a third message related to the second UE.
