Patent number: 11647424Abstract: A system and method are described that provide user-controlled Quality of Experience (QoE) in a network of resources. QoE or service parameter profiles of an SDN-NPV network are mapped to options for user selection using a QoE selector knob. The user selects the desired QoE or service parameter profile from the available options and the SDN-NPV network configuration is implemented that corresponds to the desired QoE or service parameter profile.Type: GrantFiled: October 4, 2021Date of Patent: May 9, 2023Assignee: AT&T Intellectual Property I, L.P.Inventor: Prabhakar Chitrapu

Patent number: 11395357Abstract: Devices, computer-readable media, and methods are disclosed for establishing a secure tunnel having a path that includes an untrusted link between a wireless access point and a gateway device. For example, a processor may detect a security event associated with a wireless access point that is in communication with a gateway device of the telecommunication network via a trusted link, establish a secure tunnel between the gateway device and an endpoint device that is accessing the telecommunication network via the wireless access point and the gateway device, and transport payload traffic between the endpoint device and the gateway device via the secure tunnel. A path of the secure tunnel may include an untrusted link between the wireless access point and the gateway device. In addition, the payload traffic that is transported via the secure tunnel may be indecipherable by the wireless access point.Type: GrantFiled: August 31, 2020Date of Patent: July 19, 2022Assignee: AT&T Mobility II LLCInventors: Prabhakar Chitrapu, Jayesh Sukumaran

Patent number: 11239901Abstract: Methods and apparatus are described. A wireless transmit/receive unit (WTRU) includes a transceiver and a processor operatively coupled to the transceiver. The transceiver and the processor establish a connection with a first wireless network node and a second wireless network node. The transceiver and the processor also receive power configurations and timing advances from the first wireless network node independently of the second wireless network node. The transceiver and the processor also simultaneously receive downlink signals from both the first wireless network node and the second wireless network node. The downlink signals are independently scheduled by a scheduler of the first wireless network node and a scheduler of the second wireless network node.Type: GrantFiled: April 5, 2019Date of Patent: February 1, 2022Assignee: InterDigital Technology CorporationInventors: Sana Sfar, Alexander Reznik, Prabhakar Chitrapu, Zinan Lin, Mohammed Sammour, Ana Lucia A.

Patent number: 10270518Abstract: Methods and wireless devices are described. A method includes a wireless device transmitting to wireless transmit/receive units (WTRUs) by being scheduled by the base station or using a pool of radio resources, which is for any of a plurality of wireless devices to use for transmission to WTRUs. On a condition that the wireless device is to be scheduled by the base station, the wireless device receives scheduling information for transmission to a WTRU having a group radio network terminal identifier (RNTI) and transmits to the WTRU in response to the received scheduling information. The scheduling information for transmission to the base station uses a different RNTI. On a condition that the wireless device is to use the pool of radio resources for transmission to a WTRU, the wireless device transmits to the WTRU without being scheduled by the base station using the pool of radio resources.Type: GrantFiled: December 16, 2016Date of Patent: April 23, 2019Assignee: InterDigital Technology CorporationInventors: Sana Sfar, Alexander Reznik, Prabhakar Chitrapu, Zinan Lin, Mohammed Sammour, Ana Lucia A.

Patent number: 9736733Abstract: Embodiments contemplate network stack virtualization which may be virtualization of a portion of the communication stack, such as the protocol stack, in some embodiments, multiple functionally of independent copies of the protocol stack may be simultaneously running on the terminal and/or serving the needs of different applications. This may allow independent operation from the application point of view, including connectivity to different networks with different identities. Embodiments contemplate that any number of such virtual network stacks can be instantiated, perhaps in some embodiments depending on the characteristics of an active application. Embodiments also contemplate the presentation of multiple allocated internet protocol (IP) addresses that may have sufficient information to enable an intelligent source IP address selection on the WTRU. The WTRU may be able to select an optimum IP address, perhaps in some embodiments depending on which application may be started.Type: GrantFiled: October 30, 2013Date of Patent: August 15, 2017Assignee: InterDigital Patent Holdings, Inc.Inventors: Michelle Perras, Alexander Reznik, Prabhakar Chitrapu
