Patent number: 11930425Abstract: Techniques and systems for recovering a communication session from a dedicated bearer failure are disclosed. For example, a P-CSCF node can determine that a dedicated bearer associated with a communication session has failed, and, in response, send a SIP message to a UE associated with the communication session, the SIP message causing the UE to refrain from sending SIP requests using a SIP INVITE method. The process may further include identifying a first network node associated with an identifier of the UE, the first network node comprising one of a PGW or a SMF, and sending an instruction to the first network node to dissociate the dedicated bearer from the communication session. This causes a new attach procedure to be performed by the UE to recover the session without session failure.Type: GrantFiled: October 17, 2022Date of Patent: March 12, 2024Assignee: T-Mobile USA, Inc.Inventors: Khurram Ahmad Mirza, Mohammed Al-Mehdar, Anas Said M. Jabeiti, Shujaur Mufti

Patent number: 11877342Abstract: An emergency route back number (ERBN) may be assigned for use in emergency calls. A telecommunication network associated that may be associated with a wireless service provider, may identify an emergency call directed to an emergency number (e.g., 9-1-1) that originated from a device that is not associated with a unique phone number such as a shared line, or a communication that utilizes some other indicator to establish the emergency call (e.g., an email address, or some other identifier). When an emergency call is detected that does not have a dedicated phone number, an ERBN is assigned to the communication. This ERBN may be reserved for some period of time after the emergency call ends such that emergency contact centers are able to reach callers back in case of dropped calls, fails, and/or additional emergency services that may need to reach the callers directly.Type: GrantFiled: March 2, 2021Date of Patent: January 16, 2024Assignee: T-Mobile USA, Inc.Inventors: Michele Kinsey, Adrian T. Synal, William Michael Hooker, Mohammed Al-Mehdar

Publication number: 20230088323Abstract: A network operator can partition network elements, including elements of an IP Multimedia Subsystem (IMS) or Policy and Charging Rules Functions (PCRFs) into groups reserved for specific types of subscribers. When a user equipment (UE) registers with an IMS, elements of the IMS can contact a Home Subscriber Server (HSS) to determine a subscriber type associated with the UE. Based on the UE's subscriber type, an IMS element can determine an application server or other IMS element to contact about the UE based on identifying application servers or IMS elements that are also associated with the same subscriber type as the UE. Similarly, an IMS element can determine a PCRF to contact about the UE based on identifying a PCRF that is associated with the same subscriber type as the UE.Type: ApplicationFiled: November 28, 2022Publication date: March 23, 2023Inventors: Mohammed Al-Mehdar, Saqib Badar, Shujaur Mufti, Khurram Ahmad Mirza, Kalyan Kalepu

Patent number: 11394752Abstract: When a user equipment (UE) registers with an Internet Protocol Multimedia Subsystem (IMS), a serving call session control function (S-CSCF) of the IMS can obtain user profile information associated with the UE from a Home Subscriber Server (HSS). The user profile information may include a priority indicator, such as an indication that a user associated with the UE is a Wireless Priority Services (WPS) user or other high priority user. In that situation, the S-CSCF can inform a proxy call session control function (P-CSCF) of the IMS that the user is a WPS user or other high priority user by sending a dedicated priority message to the P-CSCF, separately from sending a registration confirmation message to the P-CSCF.Type: GrantFiled: November 1, 2019Date of Patent: July 19, 2022Assignee: T-Mobile USA, Inc.Inventors: Mohammed Al-Mehdar, Boris Antsev

Patent number: 11223604Abstract: Systems and methods for preventing aggressive or abusing signaling on networks are disclosed. When a user equipment (UE), such as a cell phone, sends a request to a network (e.g., a REGISTER, SUBSCRIBE, or PUBLISH request), a network entity can start a “guard timer” and/or increment a “guard counter.” The guard timer can comprise a predetermined amount of time within which one or more additional requests from the same UE will be ignored. Similarly, the guard timer can be used in conjunction with a guard counter. The guard counter can enable a UE to make a predetermined number of requests before the guard timer expires. If the UE exceeds the guard counter before the guard timer expires, any additional requests will be ignored. When the guard timer expires, the guard counter is reset to zero to enable the UE to make additional requests.Type: GrantFiled: September 4, 2018Date of Patent: January 11, 2022Assignee: T-Mobile USA, Inc.Inventors: Hsin-Fu Henry Chiang, Mohammed Al-Mehdar

Patent number: 10491753Abstract: An application function (AF) of an IP Multimedia Subsystem (IMS) can be in communication with multiple Policy Control Function (PCF) domains of a telecommunication network. The AF can review attributes of a particular communication session, and identify a particular one of the PCF domains that corresponds to the attributes. The AF can then send a request about the communication session to a PCF element of the identified PCF domain over an Rx interface.Type: GrantFiled: March 27, 2018Date of Patent: November 26, 2019Assignee: T-Mobile USA, Inc.Inventors: Mohammed Al-Mehdar, Nassereddine Sabeur, Mayank Kaul, Shujaur Mufti, Kalyan Kalepu, Chakravarthi Japa
