  • Publication number: 20170135068
    Abstract: Control plane devices are selected by a Multimedia Broadcast Multicast Service Gateway (MGW) based on session exchange procedural triggers received from a Broadcast Multicast Service Center (BMSC). In one aspect, the MGW can employ a serving area-based Domain Name System (DNS) query/response exchange for control plane device selection that simplifies the overall complex broadcast core network architecture and design. Additionally or optionally, the MGW can employ other factors, such as, but not limited to, round trip time (RTT), load information, active/inactive link status, etc. to select the control plane devices that are to be utilized for establishing the end-to-end control plane message exchanges.

  • Publication number: 20170086123
    Abstract: 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.

  • Patent number: 9578541
    Abstract: 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.

  • Publication number: 20170013421
    Abstract: 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.

  • Publication number: 20160381662
    Abstract: 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.

  • Patent number: 9510376
    Abstract: 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.

  • Publication number: 20160330652
    Abstract: 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.

  • Publication number: 20160316351
    Abstract: 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.
