Patent number: 10412655Abstract: Aspects of the subject disclosure may include, for example, a device that determines each of a default downlink forwarding address of a first interface of a user plane and a currently used downlink forwarding address of the first interface of the user plane. One of an uplink user data packet comprising an origination address of a second interface of the user plane, a downlink user data packet comprising a destination address of the second interface of the user plane or both are received, by way of the user plane. One of the default downlink forwarding address, the currently used downlink forwarding address or both can be modified based on the uplink origination address, the destination address or both. Modification of the default downlink forwarding address, the currently used downlink forwarding address or both results in a redirection of an associated packet flow within the user plane. Other embodiments are disclosed.Type: GrantFiled: November 20, 2017Date of Patent: September 10, 2019Assignee: AT&T Intellectual Property I, L.P.Inventors: Jiansong Wang, Joseph Dahan, Ryan Redfern

Patent number: 10375528Abstract: Dynamically switching between broadcast and unicast services for service continuity between wireless networks is presented herein. A system can comprise a detection component configured to determine that a mobile device is receiving a broadcast transmission of broadcast data from a broadcast enabled access point device configured to send, via a broadcast service wireless coverage area, the broadcast data to multiple devices via a point-to-multipoint communication protocol. Further, the detection component can detect a movement of the mobile device from the broadcast service wireless coverage area to a unicast service wireless coverage area. A transfer component can initiate, in response to the detection, a unicast transmission of the broadcast data from a unicast enabled access point device to the mobile device—the unicast enabled access point device configured to send, via the unicast service wireless coverage area, the broadcast data to a single device via a point-to-point communication protocol.Type: GrantFiled: July 9, 2015Date of Patent: August 6, 2019Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Rajendra Prasad Kodaypak, Ryan Redfern, Jiansong Wang, Gaurav Gupta

Publication number: 20190239122Abstract: Aspects describe renegotiation of quality of service parameters to resolve maximum bit rate mismatches and/or other quality of service parameter mismatching issues that might arise during an inter-radio access technology handover. At about the same time as a mobile device moves from a source network to a target network, the target network dynamically initiates a quality of service modification procedure. The quality of service modification procedure can help resolve the maximum bit rate mismatches and/or the other quality of service parameter mismatching issues.Type: ApplicationFiled: April 5, 2019Publication date: August 1, 2019Inventors: Jiansong Wang, Ryan Redfern

Publication number: 20190150055Abstract: Aspects of the subject disclosure may include, for example, determining a compatibility of the mobile station with a 3GPP IMS architecture. In response to determining that the mobile station is compatible with the 3GPP IMS architecture, a transfer is facilitated of the machine-type communication message to the mobile station via a network element of an IMS network core. In response to determining that the mobile station is not compatible with the 3GPP IMS architecture a forwarding is facilitated of the machine-type communication message to a machine-type communication interworking function associated with the mobile station, wherein the machine-type communication interworking function facilitates a directing of the machine-type communication message to the mobile station via an SGs interface of a mobility management entity of an evolved packet core of a 3GPP long term evolution network. Other embodiments are disclosed.Type: ApplicationFiled: January 11, 2019Publication date: May 16, 2019Applicant: AT&T Intellectual Property I, L.P.Inventors: Rajendra Prasad Kodaypak, Christopher Bryant, Ryan Redfern, Jiansong Wang

Patent number: 9923827Abstract: Aspects of the subject disclosure may include, for example, a server comprising a memory to store instructions and a controller coupled to the memory, in which the controller, responsive to executing the instructions, performs operations. The operations include detecting a condition requiring a migration of an active transport connection at a source server to a target server without interrupting communications occurring in the active transport connection. The source server is directed to transmit to the target server a migration command with state information from the source server to enable migrating the active transport connection to the target server without interrupting communications occurring in the active transport connection. A message is then received from the source server indicating the source server has received from the target server an acknowledgment that the migrating has been performed. Other embodiments are disclosed.Type: GrantFiled: September 5, 2014Date of Patent: March 20, 2018Assignee: AT&T Intellectual Property I, L.P.Inventors: Vivek Mhatre, Ryan Redfern
