Patent number: 12627631Abstract: Aspects of the subject disclosure may include, for example, identifying, at an originating network, a recipient of a message at a terminating network, communicating a query message from the originating network to a domain name service, the query message including a query message service identifier for an inter-partner messaging service, receiving, at the originating network, a response message, the response message including a response message service identifier for the inter-partner messaging service, the response message including addressing information for communicating the message to the terminating network, formatting the message, and transmitting the message from the originating network to the terminating network based on the addressing information. Other embodiments are disclosed.Type: GrantFiled: January 9, 2024Date of Patent: May 12, 2026Assignee: AT&T Intellectual Property I, L.P.Inventor: Timothy Yao

Publication number: 20250133476Abstract: The disclosed technology is directed towards routing, by a mobile network operator, a message to a messaging hub associated with a partner carrier or to the partner carrier itself. In response to receiving a message to reroute, a data store (e.g., an ENUM database) is queried to attempt to obtain information corresponding to the routing. For example, when the query response includes a regular expression that specifies a domain, the domain is evaluated against a data structure of respective messaging hubs associated with respective domains. If the returned domain is matched such that an associated messaging hub is identified, the message is routed to the identified messaging hub; otherwise a mobile network partner carrier is determined based on the telephone number of the message recipient, and the message is routed to the determined partner carrier.Type: ApplicationFiled: December 30, 2024Publication date: April 24, 2025Inventor: Timothy Yao

Patent number: 11658969Abstract: Aspects of the subject disclosure may include, for example, receiving, by a processing system including a processor that is operative in a first communication network, a certificate from a communication device that is operative in a second communication network, extracting, by the processing system, an identifier of the communication device from the certificate, authenticating, by the processing system, the communication device in accordance with the identifier, comparing, by the processing system, the identifier with a plurality of identifiers to determine that the communication device is authorized to access data, resulting in an authorization determination, and transmitting, by the processing system, the data to the communication device based on the authorization determination. Other embodiments are disclosed.Type: GrantFiled: November 20, 2020Date of Patent: May 23, 2023Assignee: AT&T Intellectual Property I, L.P.Inventors: Timothy Yao, Christopher Bryant, Qun Wei

Patent number: 11399046Abstract: A device includes a processor and a memory. The processor effectuates operations including receiving a service capability for a mobile originating (MO) device. The processor further effectuates operations including receiving a service capability for a mobile terminating (MT) device. The processor further effectuates operations including receiving session initiation protocol (SIP) messages from the MO device at a Breakout Gateway Control Function (BGCF). The processor further effectuates operations including determining whether the received SIP messages are associated with setting up an outgoing open group chat (OGC) or an outgoing Message Session Relay Protocol (MSRP) file transfer. The processor further effectuates operations including blocking the SIP messages in response to the determination that the SIP messages are associated with setting up a MSRP file transfer.Type: GrantFiled: June 15, 2020Date of Patent: July 26, 2022Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventor: Timothy Yao
