Patent number: 11206291Abstract: Disclosed is an architecture that distributes session control logic across multiple points of a telecommunications network. Also disclosed are techniques and systems using Internet Protocol (IP)-based routing to establish communication sessions. A user equipment (UE) may receive user input to initiate a communication session, derive a destination IP address, generate a session request having at least the destination IP address, and send the session request a server. The server may receive the session request from the UE, replace the destination IP address in the session request with an IP address of an endpoint device to generate a modified session request, and route the modified session request to the endpoint device based at least in part on the IP address of the endpoint device.Type: GrantFiled: August 14, 2020Date of Patent: December 21, 2021Assignee: T-Mobile USA, Inc.Inventors: Tharunika Sridhar, Rex Maristela, Muhilan Vamadevan, Rahul Amin, Joel Arends

Patent number: 11159581Abstract: Aspects of the present disclosure include techniques for dynamically exchanging session initiation protocol (SIP) configurations between a SIP node and a neighbor SIP node. For example, a SIP node may send a first request to the neighbor SIP node to subscribe to neighbor SIP node configurations. The SIP node may then receive a second request from the neighbor SIP node for the neighbor SIP node to subscribe to SIP node configurations. The SIP node then sends the SIP node configurations from the SIP node to the neighbor SIP node and receives the neighbor SIP node configurations from the neighbor SIP node. In some aspects, the SIP node may store the neighbor SIP node configurations to a data store for formatting subsequent SIP messages exchanged between the SIP node and the neighbor SIP node.Type: GrantFiled: December 6, 2018Date of Patent: October 26, 2021Assignee: T-Mobile USA, Inc.Inventors: Rahul Amin, Muhilan Vamadevan, Joel Arends, Tharunika Sridhar, Rex Maristela

Patent number: 10637994Abstract: The disclosed system provides a Real-time Telephony (or Call) Monitor, Analyzer and Decision SIP Server (RTMADS) for mitigating attacks on emergency telephone systems. The RTMADS works in conjunction with an ingress node to fork incoming calls to an IMS network and the RTMADS. Within the RTMADS, forked telephone calls undergo data collection and mining, and parametric analysis. A decision matrix in the RTMADS uses the results of the data collection, mining, and parametric analysis, and other information, to make a decision with respect to incoming calls. For example, the RTMADS may decide to perform call setup on an incoming call using a dedicated or backup Public Safety Answering Point (PSAP), alert an Operations and Management (OAM) team regarding the incoming call, or accept and then terminate the incoming call.Type: GrantFiled: June 12, 2019Date of Patent: April 28, 2020Assignee: T-Mobile USA, Inc.Inventors: Rahul Amin, Tharunika Sridhar, Rex Maristela
