Abstract: Predicting mobile station migration between geographical locations of a wireless network can be achieved using a migration probability database. The database can be generated based on statistical information relating to the wireless network, such as historical migration patterns and associated mobility information (e.g., velocities, bin location, etc.). The migration probability database consolidates the statistical information into mobility prediction functions for estimating migration probabilities/trajectories based on dynamically reported mobility parameters. By example, mobility prediction functions can compute a likelihood that a mobile station will migrate between geographic regions based on a velocity of the mobile station. Accurate mobility prediction may improve resource provisioning efficiency during admission control and path selection, and can also be used to dynamically adjust handover margins.

Abstract: Real-time video can be efficiently and reliably streamed over wireless networks by fountain encoding a stream of video packets at the frame-level. Specifically, deep packet inspection may be performed on the stream of video packets to identify a set of video packets corresponding to an intra-coded frame (I-frame). The set of video packet may then be fountain encoded together as a data segment to produce a set of fountain encoded packets corresponding to the I-frame. Video packets corresponding to other frames (e.g., P-frames, etc.) may also be encoded on a frame-by-frame basis. This may allow a user equipment (UE) to begin displaying earlier frames in a group of pictures (GoP) while fountain encoded packets for subsequent frames are still being received, thereby reducing latency and improving the overall user experience.

Abstract translation: 通过在帧级编码视频数据包流，可以通过无线网络高效可靠地流式传输视频。 具体地，可以对视频分组流执行深度分组检查，以识别与帧内编码帧（I帧）对应的一组视频分组。 然后，该组视频分组可以一起作为数据段进行喷泉编码，以产生与I帧对应的一组喷泉编码分组。 对应于其他帧（例如，P帧等）的视频分组也可以逐帧编码。 这可以允许用户设备（UE）开始在一组图像（GoP）中显示较早的帧，而用于后续帧的喷泉编码分组仍然被接收，从而减少等待时间并改善整体用户体验。

Abstract: Hierarchical compression includes the contemporaneous implementation of link-layer and higher-layer compression on data flowing over a link. Hierarchical compression can be achieved by configuring network nodes positioned at the link-layer to recognize higher-layer compression symbols embedded in incoming data streams, and to adapt link-layer compression to compensate for those higher-layer compression symbols. One technique for adapting link-layer compression is to perform data chunking in-between higher-layer compression symbols. This may reduce the likelihood that higher-layer compression symbols will interfere with the network nodes ability to identify redundant data chunks at the link-layer. Another technique for adapting link-layer compression is to define the HASH algorithm in such a way that the hash of a data string renders the same hash value as the hash of the higher layer compression symbol corresponding to the data string.

Abstract translation: 层次压缩包括链路层和更高层压缩在链路上流动的数据的同时实现。 可以通过配置位于链路层的网络节点来识别嵌入到输入数据流中的较高层压缩符号，并适应链路层压缩以补偿那些较高层压缩符号来实现分级压缩。 用于适应链路层压缩的一种技术是在较高层压缩符号之间执行数据块分组。 这可能会降低高层压缩符号会干扰网络节点识别链路层冗余数据块的可能性。 用于适应链路层压缩的另一技术是以这样的方式定义HASH算法，即数据串的散列表示与对应于数据串的较高层压缩符号的散列相同的散列值。

Abstract: Embodiments are provided for traffic scheduling based on user equipment (UE) in wireless networks. A location prediction-based network scheduler (NS) interfaces with a traffic engineering (TE) function to enable location-prediction-based routing for UE traffic. The NS obtains location prediction information for a UE for a next time window comprising a plurality of next time slots, and obtains available network resource prediction for the next time slots. The NS then determines, for each of the next time slots, a weight value as a priority parameter for forwarding data to the UE, in accordance with the location prediction information and the available network resource prediction. The result for the first time slot is then forwarded from the NS to the TE function, which optimizes, for the first time slot, the weight value with a route and data for forwarding the data to the UE.

Abstract: Method, system and device for obtaining location information of a mobile device coupled to a wireless network. A request for a location of the device at a first set of times is transmitted by the mobile device toward a first function. A location of the device at the set of times is determined. In response to receipt of the request, the first function replies with an indication of location of the device at the specified times. The mobile device then performs a local tracking operation to determine a location of the device at another time. The local tracking operation is based on the location of the device at the specified times and local input indicative of motion of the device between at least one of the set of times and the other time.

Abstract: A method and apparatus for delivering a service to an end point, such as a UE or server, via a communication network, is provided. A virtual network is pre-configured to handle service packets and includes virtual routers for routing packets via logical tunnels. The end point pre-registers with the virtual network and/or service and receives operating parameters for use in service access. The end point location may be tracked following pre-registration. The end point subsequently transmits and/or receives service packets using the operating parameters via an edge node, such as an access node or gateway. The edge node transmits service packets using the operating parameters and, upon detecting operating parameter usage by the end point, forwards received service packets to the virtual network. Operating parameters may include an identifier included in the packet. The end point may use multiple different edge nodes to access the service.
