Patent number: 10368375Abstract: Methods and devices are described for communication using proximity services (ProSe). An aggregate maximum bit rate parameter (AMBR) may limit a data rate that may be transmitted by one or more ProSe bearers. A wireless transmit-receive unit (WTRU) may request authorization from the network prior to establishing a ProSe bearer specifying a required quality of service (QoS) or other requirements. Each ProSe bearer may have a corresponding EPS bearer to support service continuity. Packets may be evaluated by a WTRU first using a ProSe check to determine if the packet is destined for a ProSe bearer and then using a packet filter or filters in order of precedence. Embodiments may include methods of initiation communication after discovery. Embodiments may include methods of maintaining session continuity when traffic is switched between an evolved packet system (EPS) bearer and a ProSe bearer.Type: GrantFiled: October 2, 2015Date of Patent: July 30, 2019Assignee: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Mahmoud Watfa, Guanzhou Wang, Saad Ahmad, Amir Helmy, Loic Canonne-Velasquez, Dimitrios Karampatsis, Samian Kaur, Ulises Olvera-Hernandez

Patent number: 10278231Abstract: In an embodiment, a client proxy provides an operating-system-functions (OS-functions) interface to client applications. The client proxy and each of the client applications resides on a wireless transmit/receive unit (WTRU). The client proxy receives, via the OS-functions interface, respective registrations from each of a plurality of the client applications. Each respective registration indicates a respective keep-alive-message signaling rate for the corresponding registered client application. The client proxy determines an optimal signaling rate based on the respective keep-alive message signaling rates indicated by the respective registrations. The client proxy generates proxy keep-alive signaling messages that collectively convey keep-alive-message information on behalf of the registered client applications. The client proxy transmits the generated proxy keep-alive signaling messages to a network node at the determined optimal signaling rate.Type: GrantFiled: December 19, 2016Date of Patent: April 30, 2019Assignee: InterDigital Patent Holdings, Inc.Inventors: Dolores F.

Patent number: 10194359Abstract: The present invention is a method and system for station location based neighbor determination and handover probability estimation. A serving access point determines the location and movement measurements of a station (STA). Neighboring access points report coordinates of cell fringes of the neighboring access points. The STA sends a request for system information to the current access point along with current location of the STA. The current access point provides the system information, and the STA utilizes the system information to determine best handover candidate from among neighboring access points and an estimate of the time for handover.Type: GrantFiled: November 21, 2016Date of Patent: January 29, 2019Assignee: InterDigital Technology CorporationInventors: Ulises Olvera-Hernandez, Alan G.
