  • Patent number: 9055497
    Abstract: A method, system and device are provided for avoiding in-device coexistence interference between different radio technologies deployed in adjacent bands on the same device by controlling and separating the LTE signaling and the non-LTE signaling using dedicated time intervals to separate LTE signaling from non-LTE signaling. In addition, coexistence mode handover procedures are provided which use threshold-based triggering events to avoid coexistence interference and to prevent ping-pong effects by establishing a “keeping time” parameter so that a non-interfering network node does not switch back to an interfering network node after handoff.

  • Patent number: 9031543
    Abstract: Methods, devices and systems enable efficient organizations of group communications on a mobile device. The mobile device may be configured to receive location information from other mobile devices in a communication system, determine the current location and orientation of the mobile device, determine directions and distances from the mobile device to each of the other mobile devices, and generate a first-person perspective and/or top-down perspective display showing relative locations of the other mobile devices. Other multiple mobile devices may be represented in the display as images (e.g., icons, avatars, directional indicators, etc.). The display may provide a user interface to enable a user to quickly organize other mobile devices into groups and initiate group communications with some of the other mobile devices. The mobile device may be configured to group the displayed images into one or more communication units and establish communication links with mobile devices in the communication units.

  • Patent number: 9014691
    Abstract: Performance issues of wireless equipment (WE) or a wireless network are diagnosed through an alternative communication channel enabled by an alternative wireless network available to the WE. A service platform (SP) probes performance condition of the WE through a mobility control node (MCN) and, in response to a fault condition, collects data related to operation of the WE. Based at least on part of the data, the SP diagnoses the fault condition and related performance issue(s). To probe performance, the SP requests the MCN to collect data related to performance metric(s) of the WE. The alternative communication channel is established, and such data is collected therefrom, in response to low-grade connectivity amongst the MCN and the WE. The SP notifies the WE of at least the fault condition through the MCN or, in case of network fault condition, via the alternative communication channel.

  • Patent number: 9002412
    Abstract: The disclosed embodiments relate to a system that enables a user to continue accomplishing a task on a handheld device while moving. During operation, the system tracks the speed of the handheld device while the user is interacting with an application on the device. If the speed is greater than a pre-determined speed, the system audibly prompts the user to enable hands-free mode. If the user says yes, the system enables hands-free mode and the user may continue to use the application in hands-free mode. Otherwise, the system continues to run the application without enabling hands-free mode.

  • Patent number: 8942688
    Abstract: Methods and systems are described for routing call in a wireless network environment. In one embodiment, a phone address is assigned to a subscriber and/or a subscriber's mobile telecommunications device. A call directed to the phone address is routed to a call processing system. An outbound call from the call processing system is placed to a wireless communication service provider so as to cause, at least in part, the wireless communication service provider to route the outbound call to the subscriber's mobile telecommunications device, wherein the call processing system configures call signaling parameters associated with the outbound call so that the outbound call appears to be to a phone number ported to the wireless communication service provider, and wherein the phone number has not been ported to the wireless communication service provider. The outbound call is bridged with the inbound call.

  • Patent number: 8885572
    Abstract: Methods and apparatus supporting peer to peer communications are discussed. A base station, serving as an access node for wireless terminals also communicates information supporting peer to peer communications. A base station transmits a beacon signal conveying information about a peer to peer frequency band and also receives user data from a plurality of wireless terminals, using the base station as a current point of network attachment. In some embodiments, the beacon signal is transmitted into the same frequency band being used for access node based communications and identifies a different frequency band which is to be used as a peer to peer frequency band. Alternatively, or in addition, in support of peer to peer communications, a beacon signal transmission apparatus, a free standing device which doesn't transmit user data, transmits a sequence of beacon signal bursts, each beacon signal burst including at least one high power beacon symbol.

  • Patent number: 8886228
    Abstract: A system and method are disclosed for triggering location estimation of mobile stations in a geographic region of interest. The disclosed system includes a list of International Mobile Subscriber Identities (“IMSI”) used to track which mobile stations are to have location estimates generated, a database of Network Measurement Reports (“NMR”) used for generating the location estimates, and a location engine. The system operates as a group of concurrently executing processes that i) process IMSIs and NMRs that are extracted by and received from probes that monitor communication links; ii) generate location estimates of mobile stations in the region of interest, based on a sequential indexing of the IMSI list; iii) maintain the freshness of the NMR database; and iv) maintain the freshness of the IMSI list. These processes operate such that the triggering of the location estimations occurs asynchronously with respect to the detection of information on the communication links.

  • Patent number: RE45260
    Abstract: A method for locating a user in a wireless network is disclosed. A mobile computer seeking to determine its location within a building detects the signal strength of one or more wireless base stations placed at known locations throughout the building. The mobile computer uses this measured signal strength to determine its location via a signal-strength-to-location table look-up. A table of known locations within the building and the base station signal strength at those locations is searched to find the most similar stored signal strength to the signal strength detected. The location corresponding to the most similar stored signal strength is determined to be the current location of the mobile computer. Alternatively, a number of signal strengths from the table can be used and the corresponding locations can be spatially averaged to determine the location of the mobile computer.
