Publication number: 20240064680Abstract: A wireless communication network handles Session Management Function (SMF) outage in a Tracking Area (TA). An external SMF that is outside the TA registers with an internal Network Repository Function (NRF) that is inside in the TA. The internal NRF detects the SMF outage for an internal SMF inside the TA. The internal NRF receives an SMF request from an internal Access and Mobility Management Function (AMF) inside the TA. In response to the SMF outage, the internal NRF transfers an SMF response to the internal AMF that indicates the external SMF. The external SMF receives network signaling from the internal AMF and responsively directs an external User Plane Function (UPF) that is outside the TA to exchange user data with internal wireless access nodes that are inside the TA.Type: ApplicationFiled: August 18, 2022Publication date: February 22, 2024Inventors: Kunal Prakash Barawkar, John Paul Tuscano Cruz, Swetha Gopisetti, Aziz Motiwala, Praveen Singaram Muthukumar, Rahul Pal, Rushabhkumar Dahyabhai Patel, Suresh Thanneeru

Patent number: 11871330Abstract: Systems, devices, and techniques described herein relate to migrating a communication session from a path including a stressed user plane function (UPF) to a path including a replacement UPF. A communication session may traverse a first path including the first UPF. After establishing the communication session, the first UPF may be determined to be stressed. In response, the communication session can be proactively migrated to a second path including a second UPF. According to various implementations, the existing communication session can be maintained during the migration, thereby substantially eliminating interruptions caused by the stressed first UPF.Type: GrantFiled: October 31, 2022Date of Patent: January 9, 2024Assignee: T-Mobile USA, Inc.Inventors: Suliman Albasheir, Boris Antsev, Christopher H.

Patent number: 11777855Abstract: Policy based dual connectivity traffic steering is described herein. A master Long-Term Evolution (LTE) base station may operate in conjunction with a secondary New Radio (NR) base station to provide dual connectivity to user equipment (UE) operating in an environment. The LTE base station can steer traffic between the LTE base station and the NR base station based at least in part on policy information received at the LTE base station. The policy information can indicate, for a particular UE and for a particular Quality of Service (QoS) Class Identifier (QCI), whether the LTE base station can transfer a communication to the NR base station. Thus, traffic steering determinations can be based on the policy information, quality identifiers, device capability, signal strength(s), load level(s), and the like, thereby providing a flexible framework for steering wireless traffic in a dual connectivity environment.Type: GrantFiled: December 14, 2020Date of Patent: October 3, 2023Assignee: T-Mobile USA, Inc.Inventors: Suresh Thanneeru, Salvador Mendoza

Patent number: 11743704Abstract: Techniques for handling emergency calls in a fifth generation (5G) telecommunication network are discussed herein. Some 5G-compatible user equipment (UEs) support 5G emergency calls, while other 5G-compatible UEs do not support 5G emergency calls. If a UE supports 5G emergency calls, the 5G telecommunication network may instruct the UE during network registration to use the 5G telecommunication network for any emergency calls attempted later. However, if a UE does not support 5G emergency calls, the 5G telecommunication network may instruct the UE during network registration to instead use Long-Term Evolution (LTE) emergency fallback procedures for emergency calls. Such LTE emergency fallback procedures can cause the 5G telecommunication network to steer the UE to LTE for an emergency call almost immediately after receiving a service request from the UE, even though the 5G telecommunication network itself supports emergency calls.Type: GrantFiled: February 9, 2021Date of Patent: August 29, 2023Assignee: T-Mobile USA, Inc.Inventors: Suresh Thanneeru, Christopher H. Joul, Boris Antsev, William Michael Hooker

Patent number: 11716677Abstract: Systems, devices, and techniques described herein relate to prioritizing access by first user equipment (UEs) connected to a first radio access technology (RAT) type over access by second UEs connected to a second RAT type responsive to a failure of a core network node. A node of the core network, such as a session management node, may determine that another node of the core network has failed based on a negative response or no response from that other node. The node may then prioritize access based on RAT types of requesting UEs.Type: GrantFiled: April 1, 2021Date of Patent: August 1, 2023Assignee: T-Mobile USA, Inc.Inventors: Muhammad Waqar Afzal, Suresh Thanneeru, Suliman Albasheir, Rahul Pal, Karunakalage Viraj Rakitha Silva

Publication number: 20230117232Abstract: Restricting mobility between networks by identifying and rejecting incoming mobility events (e.g. handovers) from unknown cell sites based on a cellID included in a handover request. Core network nodes e.g. MME, AMF, SMF, can detect and reject the incoming mobility events by comparing Cell ID with a white list or referring to a database. This improves over current 3GPP specifications and network vendor implementations that support restriction policies on the source but not on the target.Type: ApplicationFiled: December 22, 2022Publication date: April 20, 2023Inventors: Suresh THANNEERU, Romil SOOD

Publication number: 20230062145Abstract: In a telecommunication network, network slices can be identified by slice identifiers used within a core network. The same slice identifiers can also be used by elements of an IP Multimedia Subsystem (IMS) to identify the network slices. For example, a Home Subscriber Server (HSS) can be provisioned with user data associated with a user equipment (UE), including a slice identifier of a network slice that the UE is assigned to use. The HSS can provide the slice identifier to an S-CSCF in the IMS when the UE registers with the IMS. The S-CSCF can share the slice identifier with other IMS elements, such as a P-CSCF and/or one or more application servers. Accordingly, the IMS elements can determine key performance indicators (KPIs) and perform other operations in association with usage of network slices by UEs, based on the same slice identifiers used within the core network.Type: ApplicationFiled: August 26, 2022Publication date: March 2, 2023Inventors: Nassereddine Sabeur, Saqib Badar, Shujaur Rehman Mufti, Suresh Thanneeru, Boris Antsev, Christopher H.

Patent number: 11444827Abstract: A telecommunication system can include a network flow controller (e.g., SMF) and a network-charging node (e.g., CHF). The flow controller can generate a first charging-event record associated with a network session. The flow controller can detect an outage at least partly by determining that no network-charging node is available to receive the first charging-event record and, in response, mark the first charging-event record to provide a first marked charging-event record. The flow controller can store the first marked charging-event record in a buffer. After the marking, the flow controller can determine that a network-charging node is available to receive the first marked charging-event record, and, in response, send the first marked charging-event record to the network-charging node. The network-charging node can determine a charging-data record indicating occurrence of an event during the outage.Type: GrantFiled: December 21, 2020Date of Patent: September 13, 2022Assignee: T-Mobile USA, Inc.Inventors: Muhammad Waqar Afzal, Karunakalage Viraj Rakitha Silva, Suresh Thanneeru, Rahul Pal, Nader Nabil Farouk Riad, Suliman Albasheir
