Patent number: 9578541Abstract: Aspects of the subject disclosure may include, for example, determining message transfer delays based on transport layer control information associated with network traffic of a backhaul network coupled between a number of core network nodes of a wireless network and a wireless access node of the wireless network. The message transfer delays are representative of the network traffic between the core network nodes and the wireless access node. Weighting factors are assigned to the core network nodes based on the message transfer delays. The weighting factors are exposed to a scheduler that identifies a first group of core network nodes and a second group of core network nodes based on the weighting factors. The wireless access node preferentially establishes communications via the first group of core network nodes. The wireless access node establishes communications via the second group, responsive to an inability to establish communications via any core network nodes the first group.Type: GrantFiled: April 6, 2015Date of Patent: February 21, 2017Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Vikram Seenappa, Rajendra Prasad Kodaypak, Jiansong Wang

Publication number: 20170013421Abstract: 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: ApplicationFiled: July 9, 2015Publication date: January 12, 2017Inventors: Rajendra Prasad KODAYPAK, Ryan REDFERN, Jiansong WANG, Gaurav GUPTA

Publication number: 20160381662Abstract: Aspects of the subject disclosure may include, for example, control signals are communicated with a base station of a radio access network in communication with a mobile device. The control signals include information associated with one of mobility of the mobile device, bearer management or both. The network node communicates bearer message traffic with the base station and coordinates an exchange of data packets between the base station and an external packet data network by way of the bearer message traffic. Other embodiments are disclosed.Type: ApplicationFiled: June 29, 2015Publication date: December 29, 2016Inventors: Jiansong Wang, Ryan Redfern

Patent number: 9510376Abstract: A system that incorporates the subject disclosure may include, for example, receiving from a wireless device a request for a network connection and facilitating, in response to the request, a communication session between a wireless access node in communication with the wireless device and a packet data network. Control signals are exchanged between a second network device and a packet data network gateway. The second network device includes a mobility anchoring function and operating in an evolved packet core of a long term evolution system. Eligibility of the wireless communication device to participate in a direct tunnel connection is determined, the direct tunnel allowing transfer of user data packets between the wireless device and packet data network to bypass the mobility anchoring function. Establishment of the direct tunnel connection is facilitated to transfer multiple user data packets between the wireless device and the packet data network.Type: GrantFiled: September 25, 2013Date of Patent: November 29, 2016Assignee: AT&T Intellectual Property I, L.P.Inventors: Jiansong Wang, Ryan Redfern

Publication number: 20160330652Abstract: 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: July 22, 2016Publication date: November 10, 2016Inventors: Jiansong Wang, Ryan Redfern

Publication number: 20160316351Abstract: Aspects of the subject disclosure may include, for example, a device, process or software that receives data for distribution to a multiple mobile devices, wherein the distribution is via a data dissemination service. A request is sent to a core network element over a control signaling interface to establish a wireless bearer service. The wireless bearer service can be used to wirelessly distribute the data to the multiple mobile devices via a radio access node. A confirmation is received of the establishment of the wireless bearer service, and the mobile user service is announced over the wireless bearer service. The data is forwarded to the radio access node via a wireless terrestrial bearer of the wireless bearer service, wherein the radio access node wirelessly distributes the data to the number of mobile devices via the mobile user service over a common radio channel. Other embodiments are disclosed.Type: ApplicationFiled: April 27, 2015Publication date: October 27, 2016Inventors: Rajendra Prasad Kodaypak, Ryan Redfern, Jiansong Wang
