  • Publication number: 20120252512
    Abstract: A method of data transfer between wireless transmit/receive units (WTRUs) is described. The WTRUs may be within a given geographic area of each other or in communication with the same network. Location information relating to the WTRUs may be determined. The location information may be presented to a user of the WTRU. Data may be transferred from one WTRU to a target WTRU based on user input. The WTRU may determine the target WTRU based on user input and/or location information. The user input may be a gestural input. The gestural input may be received via a display or touchscreen. The user input may identify a given action or identify a particular file for transfer. The WTRU may receive data from the target WTRU.

  • Patent number: 8238261
    Abstract: A method and apparatus for improving handover in an IEEE 802.21 compliant communication network. A query is transmitted from a wireless transmit/receive unit (WTRU) to a media independent handover (MIH) server (MIHS). The WTRU includes a target point of attachment (PoA) and/or a preferred mobile inter protocol (MIP) method. The WTRU receives a response from the MIHS indicating the MIP method supported by the target PoA. Based on the received response, the WTRU may make an informed decision regarding handover.

  • Patent number: 8200265
    Abstract: A method of data transfer between wireless transmit/receive units (WTRUs) is performed by a sending communication device soliciting environment information relating to active communication devices operating within the local area of the WTRU. The local area of the WTRU may be determined by an environment variable that may be configured to indicate a search radius. Within the local area, information relating to active candidate WTRUs is received through a communication peripheral. User actions on the user interface are converted to electromechanical signals which act as an input along with the environment information to select a target WTRU from the candidate WTRUs to receive the data transfer. The environment information and user input are used to uniquely discriminate the target WTRU as the intended recipient of the data transfer. Transmission instructions are generated based on the solicited information and the user input.

  • Patent number: 8134978
    Abstract: A radio interface layer media independent handover (RIL MIH) client functionality enables transparent inter-system handover of a wireless transmit/receive unit (WTRU) between different radio access technologies (RATs), without user intervention. The RIL MIH client interacts with RIL drivers and proxies, informs the RIL proxies of the handover status, then the proxies interact with a new driver in use. A WTRU is modified to add MIH functionality to a telephony server to support inter-system handover.

  • Patent number: 7877494
    Abstract: A privacy service is provided for use in protection of user data transferred in a network, including a converged network. The privacy service extracts and measures service elements of a message containing user data. The service elements include an identity element, a trust element, a rights element and a security element. The privacy service performs security by comparing service elements with a user defined privacy policy. The privacy policy may also be based on particular factors relating to the application, context, and time of the message. In another embodiment, the privacy service provides controls that indicate when user data is misappropriated as a result of an infringement of the user defined privacy policy. Further the privacy service provides a means to audit and trace deviations from the privacy policy for the purpose of repudiation, or future defense of security threats.

  • Publication number: 20090170555
    Abstract: A mobility service and control function (MSCF), operating in an application layer of a wireless transmit/receive unit (WTRU), selects and controls a plurality of mobility services. These mobility services may include session initiation protocol (SIP), Internet protocol (IP) Multimedia subsystem (IMS), voice call continuity (VCC), mobile IP (MIP), proxy MIP (PMIP), and generic access network (GAN), but are not limited thereto. The MSCF further selects and controls a plurality of air interface technologies for accessing a plurality of radio access networks. The MSCF allows application layer handling of mobility management.

  • Publication number: 20080253313
    Abstract: A method and apparatus for integrating a Voice over Internet Protocol (VoIP) client in a wireless PC card are disclosed. A soft mobile phone client is combined with a cellular PC card to create a single physical device that is capable of providing VoIP services to a computer user through the cellular capabilities of the device itself, or alternatively, through any other Internet connectivity available to the computer. When a user inserts the VoIP client/Cellular PC Card into a computer, a graphical user interface (GUI) within the connection manager software is launched allowing the user to communicate VoIP function commands to the VoIP client. A check for Internet connectivity may be performed, at which time the Radio portion of the enhanced PC card may be put into an idle state if connectivity is detected, or may alternatively establish Internet connectivity through the cellular portion of the enhanced PC card.
