Patent number: 11122471Abstract: Registration of a user equipment (UE) with a circuit-switched (CS) network can be controlled in an “on-demand” fashion by waiting for a trigger event before registering the UE with an available CS network. In some embodiments, CS registration of a UE may be triggered when the mobility management entity (MME) node receives, from the UE, a service request that was sent using Non-Access Stratum (NAS) protocol, such as an extended service request (ESR) or a short message service (SMS) over NAS request. In some embodiments, CS registration of a first UE may be triggered when the MME node receives, from a home subscriber server (HSS), a notification of an incoming session request originating from a second UE to establish a communication session over a CS network with the first UE.Type: GrantFiled: October 4, 2019Date of Patent: September 14, 2021Assignee: T-Mobile USA, Inc.Inventors: Hsin-Fu Henry Chiang, Suresh Thanneeru, Syed Toaha Ahmad, Boris Antsev

Publication number: 20210250745Abstract: 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: ApplicationFiled: February 9, 2021Publication date: August 12, 2021Inventors: Suresh Thanneeru, Christopher H. Joul, Boris Antsev, William Michael Hooker

Patent number: 11076436Abstract: A core network element, such as a PCRF and/or an MME, can determine that a Quality of Service (QoS) Class Indicator (QCI) of particular bearer set up between the core network and user equipment (UE) should be changed to a new QCI. When a control node, such as the MME, determines that no teardown delay conditions are met, the control node can send a bearer release message to a base station that instructs the base station to tear down all bearers for the UE, even if they are in use. In a dual connectivity arrangement, such as a E-UTRAN New Radio-Dual Connectivity (EN-DC) configuration, the base station can instruct a secondary base station to also release all bearers for the UE. The control node can instruct the base station to reestablish the particular bearer with the new QCI when the base station reestablishes the bearers for the UE.Type: GrantFiled: December 12, 2018Date of Patent: July 27, 2021Assignee: T-Mobile USA, Inc.Inventors: Kun Lu, Jun Liu, Christopher H.

Patent number: 11057811Abstract: When using Dual Connectivity in a Non-Standalone Architecture cellular communication system, a data bearer may be steered through a Long-Term Evolution (LTE) base station or a New Radio (NR) base station. Each bearer is assigned a combination of Quality of Service (QoS) values corresponding to the service type that the bearer is supporting. For example, each different service type may be assigned a combination of a QoS Class Identifier and an Allocation and Retention Priority parameter value. Each combination is also associated with a radio access technology such as LTE radio access technology or NR radio access technology. When NR communications are available between a network core and a communication device, and if the bearer's combination of QoS values has been associated with NR, bearer data is routed through an NR base station. Otherwise, the bearer data is routed through the LTE base station.Type: GrantFiled: December 14, 2018Date of Patent: July 6, 2021Assignee: T-Mobile USA, Inc.Inventors: Kun Lu, Ming Shan Kwok, Salvador Mendoza, Alan Denis MacDonald, Jun Liu, Egil Gronstad, Karunakalage Viraj Rakitha Silva, Suresh Thanneeru

Publication number: 20210144051Abstract: 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: ApplicationFiled: December 21, 2020Publication date: May 13, 2021Inventors: Muhammad Waqar Afzal, Karunakalage Viraj Rakitha Silva, Suresh Thanneeru, Rahul Pal, Nader Nabil Farouk Riad, Suliman Albasheir

Publication number: 20210099390Abstract: 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: ApplicationFiled: December 14, 2020Publication date: April 1, 2021Inventors: Suresh Thanneeru, Salvador Mendoza

Patent number: 10924913Abstract: A cellular network may provide location services so that clients such as public service access points (PSAPs) can obtain locations of mobile devices. A location request is received first by a Gateway Mobile Location Center (GMLC), which responds by querying a Mobility Management Entity (MME). The MME is configured to query a Serving Mobile Location Center (SMLC) for the location. In some cases, the SMLC fail to respond or may respond with an error indication. In response to certain types of errors, the MME is configured to attempt to obtain the requested location from an alternate SMLC, rather than reporting an error back to the GMLC. Status information is maintained by the MME to keep track of any SMLCs that have returned errors, and these SMLCs are avoided when processing further requests.Type: GrantFiled: April 18, 2018Date of Patent: February 16, 2021Assignee: T-Mobile USA, Inc.Inventor: Suresh Thanneeru
