20150271855 | DETERMINING A LOCATION OF A DEVICE FOR CALLING VIA AN ACCESS POINT - Methods and systems are described for determining a physical location for a voice over packet (VoP) device engaging in voice communication via an access point. Associations between one or more physical locations and access points may be stored in a profile associated with the VoP device or a user. If the VoP device is connected to a particular access point, the profile and associations may be used to determine a current physical location for the VoP device, and for voice communications involving the VoP device. | 2015-09-24 |
20150271856 | MOBILE COMMUNICATION SYSTEM, USER TERMINAL, PROCESSOR, AND BASE STATION - A mobile communication system, which supports D2D communication that is direct device to device communication, comprises: a user terminal that transmits a discovery signal that is used for discovering a communication partner terminal in the D2D communication, wherein the user terminal transmits the discovery signal when the user terminal accepts start of communication and the user terminal has difficulty to establish a connection with a base station. | 2015-09-24 |
20150271857 | SHORT IDENTIFIERS FOR DEVICE-TO-DEVICE (D2D) BROADCAST COMMUNICATIONS - Methods, apparatuses, systems, and computer program products for transmitting/receiving scheduling assignment(s) (SAs) are provided. One method is directed to including a short version of a target ID (i.e., short ID) in a SA. The method may also include transmitting the SA including the short ID to one or more monitoring UE(s). The monitoring UE(s) may then compare the short ID to target ID(s) being monitored. The corresponding data from the SA may be decoded if there is a match between the short ID and any of the target ID(s). | 2015-09-24 |
20150271858 | BLUETOOTH-BASED SYSTEM FOR AUTOMATICALLY MATCHING VEHICLE-MOUNTED DEVICE WITH MOBILE PHONE TERMINAL - The disclosure discloses a Bluetooth-based system for automatically matching a vehicle-mounted device with a mobile phone terminal. The system controls a vehicle-mounted device and a mobile phone terminal to turn on/off their respective Bluetooth function based on a vehicle ignition switch signal. In such a way, the driver needn't to turn on, match, and turn off the Bluetooth functions of the vehicle-mounted device and the mobile phone terminal manually. More intelligentized, convenient and efficient service is provided for the drivers and the power of the mobile phone terminal can be saved. | 2015-09-24 |
20150271859 | MEASUREMENT REPORTING IN D2D COMMUNICATION - An apparatus is provided for use in a User Equipment, UE, comprising an input to receive an information element, IE, during a device-to-device, D2D, communication session with another UE, the IE indicating whether or not the UE is to send a measurement report; a processing section to determine based on the indication; and an output to control transmission by the UE, the processing section being arranged to suppress participation in measurement reporting when it is determined that a measurement report is not to be sent. A related apparatus is provided for use in an evolved Node B, eNB, and related methods are also provided. | 2015-09-24 |
20150271860 | SIGNALING FLOWS AND BUFFER STATUS REPORT FOR A GROUP IN DEVICE-TO-DEVICE BROADCAST COMMUNICATION - Methods, systems, and devices are described for device-to-device (D2D) wireless communication. A device may transmit an initiation message to a base station indicating that the device desires to initiate a D2D communication session. The device may then receive a response from the base station that includes parameters for configuration of the D2D session. When it has data to send to another device, the device may transmit buffer status report (BSR) to the base station. The base station may respond with a grant of D2D scheduling assignment (SA) configured according to the previously sent parameters. For example, the message may be scrambled with a D2D temporary identity sequence. In some cases, the device may transmit a group identification (ID) code to the base station, and the group ID may be associated with an index, so an SA for that group can be reference by index. | 2015-09-24 |
20150271861 | METHODS AND APPARATUS FOR DEVICE TO DEVICE SYNCHRONIZATION PRIORITY - A Device to Device (D2D) user equipment (UE) is configured to support synchronization in a D2D network. The D2D UE includes an antenna configured to communicate via a D2D communication. The D2D UE also includes processing circuitry configured to enter a communication Mode 2 when certain conditions are met. The certain conditions include: when a first timer (T | 2015-09-24 |
20150271862 | Method of Handling Device-to-Device Operation and Related Communication Device - A method of handling a device-to-device (D2D) operation for a communication device comprises determining a first subframe for performing a device-to-cellular (D2C) operation to a network, performing the D2C operation in the first subframe when the D2C operation does not collide with a D2D operation, and performing the D2C operation in the first subframe and stopping the D2D operation in the first subframe when the D2C operation collides with the D2D operation. | 2015-09-24 |
