Patent number: 9729588Abstract: Managing Security Parameter Information (SPIs) to prevent race condition failures begins where a system negotiates SPIs along with associated expiration times, and re-negotiates new SPIs as necessary. The system prevents race conditions that would otherwise occur when both an old SPI and a new SPI are active at the same time. The system accomplishes this by managing the storage and deletion of old SPIs such that only active SPIs are stored on the system for use by a User Equipment (UE) or Proxy Call Session Control Function (P-CSCF).Type: GrantFiled: June 2, 2015Date of Patent: August 8, 2017Assignee: T-Mobile USA, Inc.Inventors: Kalyan Kalepu, Shujaur Mufti

Patent number: 9686818Abstract: In example embodiments disclosed herein, a primary wireless device infrequently sends a ping to a secondary device to determine if there are any communications from an access point intended for the primary wireless device. The secondary device, ideally connected to wall power, is wirelessly connected to the access point, acting as a connected proxy so that the primary wireless device, typically battery powered, does not always have to be connected. In a situation in which an incoming communication is intended for the primary device, the secondary device receives the notification and buffers whatever is sent from the access point intended for the primary wireless device and acknowledges the receipt. Then, when the primary wireless device pings the secondary device, the secondary device sends the buffered communication to the primary wireless device. As far as the access point is concerned, it thinks it is communicating directly with primary wireless device.Type: GrantFiled: September 2, 2014Date of Patent: June 20, 2017Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Leo Estevez, Baher Haroun

Patent number: 9681256Abstract: A method and apparatus are provided for abbreviating the blind decoding process performed by a UE, such as an LTE UE, on control channel data such as PDCCH data of PRB pairs of a set of PRB pairs transmitted concurrently within a subframe. In some embodiments, only a prioritized portion of the PDCCH data is decoded, thereby expediting blind decoding. In some embodiments, a reduced number of encoding options for the PDCCH data is used, and blind decoding is expedited by considering only such options as possibilities. When blind decoding of the PDCCH data is completed before the end of the subframe, this may be used to identify and discard corresponding PDSCH data which is irrelevant to the UE. The prioritized portion may be adjusted as needed to include the CSS so as not to miss certain critical data.Type: GrantFiled: March 15, 2014Date of Patent: June 13, 2017Assignee: Sierra Wireless, Inc.Inventors: Gustav Gerald Vos, Naveen Mysore Balasubramanya, Lutz Hans-Joachim Lampe, Steven John Bennett

Patent number: 9655039Abstract: The disclosure generally relates to dynamic cell reselection to improve device-to-device (D2D) communications where two or more D2D peers are camped onto different cells and one or more D2D peers are located in an overlap region between the cells. For example, in various embodiments, the D2D peers may exchange one or more communication parameters over the (inter-cell) D2D connection and detect that the D2D peers are camped on different base stations (i.e., attached to different cells) based on the exchanged communication parameters. The D2D peer(s) located in the cell overlap region may then obtain measurements on the neighbor cell and a forced cell reselection may be triggered at the appropriate D2D peer(s) located in the cell overlap region such that the D2D peers are camped on the same base station, thereby converting the inter-cell D2D connection into an intra-cell D2D connection that can be more easily maintained.Type: GrantFiled: June 26, 2015Date of Patent: May 16, 2017Assignee: QUALCOMM IncorporatedInventors: Parthasarathy Krishnamoorthy, Anand Rajurkar, Prashanth Mohan, Aravinth Rajendran, Janga Reddy Alimineti, KrishnaKumar Vasanthasenan
