20140192667 | Proximity Offloading and Service Continuity Support for Mobile Communication Devices - Systems and methods are provided to facilitate direct wireless communication between mobile communication devices while avoiding the need for mobile communication devices to periodically scan for in-range devices and avoiding unwanted breaks in traffic caused by changes in the source and/or destination IP address of packets. Mobile communication devices periodically update their positions to a server, which can send a notification when a mobile communication device comes within range. Further, mobile communication devices can encapsulate packets with an IP address used for direct wireless communication to facilitate this direct wireless communication without disrupting traffic over a core network. | 07-10-2014 |
20140192737 | Proximity Detection for Mobile Communication Devices Using Geo-Fencing - Systems and methods are provided for using geo-fencing techniques to assist in detecting mobile communication devices that are close enough to support direct communication. A mobile communication device can periodically report its geo-fence area to a central server. The server can determine whether to ask the communication device to report more precise geographic information (e.g., GPS information) based on whether another communication device eligible for direct communication is within the same geo-fence area. | 07-10-2014 |
20140211648 | SYSTEM AND METHODS FOR ANONYMOUS CROWDSOURCING OF NETWORK CONDITION MEASUREMENTS - A communication device and method for crowdsourcing of information from one or more communication devices. The crowdsourced information can be defined by one or more parameters defined in an operational framework. The operational framework can be, for example, an Access Network Discovery and Selection Function (ANDSF) framework. The operational framework can include, for example, positional and/or movement information of the communication device(s), a signal quality of a communication network, a visibility duration of a communication network, data rate information of a communication network, and/or quality of service (QoS) information of a communication network. | 07-31-2014 |
20140242979 | CELLULAR NETWORK INTERWORKING INCLUDING RADIO ACCESS NETWORK EXTENSIONS - A communication device and method for offloading one or more communications from a communication network to one or more other communication networks. The offloading can be controlled by one or more service providers that instruct the communication device to perform the handoff of communications. For example, the one or more service providers can generate one or more commands that instruct the communications device to scan for one or more networks, identify one or more networks, analyze one or more of the identified networks, generate one or more reports based on the analysis, and/or provide the generated reports to the service provider(s). | 08-28-2014 |
20140301258 | SIP SIGNALING CUT-THROUGH - Systems and methods are provided for reducing power consumption in a mobile device having a Internet Protocol (IP) multimedia subsystem (IMS) framework for supporting, e.g., Voice over Long Term Evolution (VoLTE), IP Voice over High Speed Packet Access (VoHSPA), and Rich Communication Suite (RCS) features. To support such functionality in a mobile device while reducing power consumption, a local Session Initiation Protocol (SIP) agent is implemented in, e.g., a wireless modem, of the mobile device to which SIP-related signaling can be redirected, and at which SIP-related processing can be performed when an application processor (AP) Of the mobile device is in sleep mode, thereby negating a need to wake up the AP to handle such functionality. | 10-09-2014 |
20140362778 | Method and Apparatus for Voice Over LTE and Data Handling in a Roaming Environment - An approach for reducing online charging for voice over LTE users when accessing a roaming network. Users can receive and make voice over LTE calls without allowing background applications to use the resulting bearer for data traffic such as firmware updates, social network applications and other periodic and aperiodic data traffic. This approach has a beneficial impact on charging costs when accessing roaming networks. | 12-11-2014 |
20140364118 | Method and Apparatus for Incoming Call Detection in a Dual SIM Single RF Communication Device - A method and apparatus to co-ordinate detection of incoming calls in a multimode dual-SIM single RF chain wireless communications device. Incoming voice over LTE calls cannot be detected by monitoring LTE paging messages. The method and apparatus described detect voice over LTE incoming call SIP signaling in one SIM while also perform paging monitoring for a circuit-switched call in another SIM in the dual-mode dual-SIM communication device. Using a duty cycle that alternates priority between LTE and circuit-switched monitoring ensures that no incoming voice call or text message will be missed. | 12-11-2014 |
20140364167 | MOBILE COMMUNICATION DEVICE WITH MULTIPLE WIRELESS TRANSCEIVERS AND METHODS FOR USE THEREWITH - A first wireless transceiver communicates pre-association data via a first wireless network, the pre-association data relating to a second wireless network, wherein the first wireless network supports communication via a first wireless protocol and wherein the second wireless network supports communication via a second wireless protocol that is different from the first wireless protocol. A second wireless transceiver communicates the pre-association data with the first wireless transceiver via a transceiver interface and processes the pre-association data to support an association by the second wireless transceiver with the second wireless network. | 12-11-2014 |
