摘要： Some embodiments of the invention provide an implementation for a multi-hop wireless backhaul network. These embodiments can advantageously be deployed in dense urban areas and/or co-located with wireless access nodes, such as base-stations of a cellular wireless communication system. Preferably wireless links between constituent network nodes are set-up hierarchically. A basic result of this is that peer-to-peer (child-to-child) communication is generally prohibited and circuits are forced to conform to a topology. The multi-hop wireless backhaul network may be used to carry delay sensitive, high-density last mile circuit traffic over Non-Line-Of-Sight (NLOS) broadband radio links. Moreover, some embodiments of the invention provide a method of path-healing for re-routing of circuit traffic from circuits that have experienced catastrophic failures.

摘要： A method and apparatus for routing packets to a destination end point over a virtual network (VN) pre-configured on a network. The routing is performed by a VN virtual router (v-router) associated with a node of the VN. The v-router receives a data packet, obtains an indication of location of the destination end point from a connection management (CM) entity tracking the end point, and selects a logical tunnel or next VN node to forward the data packet to. The CM entity tracks end points upon registration and provides updates upon a request or other trigger.

摘要： The present application provides a method for routing traffic from a user equipment (UE) to a service available on a network. In the method, a virtual router entity that services a virtual network available on the network receives a packet from the UE, the received packet including at least a destination ID and payload. The virtual router then forwards a location resolution request including the received destination ID to an associated connectivity manager operating on the network. The virtual router receives a location resolution response from the connectivity manager including at least a destination network node ID. The virtual router may then forward the packet to the destination network node ID.

摘要： A system supporting a networked database service includes a controller configured to receive one or more data request and authenticate the one or more data request. A gateway (GW) in communication with the controller, is configured to receive at least one of the one or more data request from the controller, perform data classification on data received in the request, and generate a cryptographic key based on the data classification, a hardware-protected key of the GW, and a second (encryption) key. The cryptographic key is for accessing a database. The controller and the GW are operated by different parties.

摘要： Methods and systems for data management in communication networks. An aspect provides a system including a first network function and a second network functions. The first network function is configured for collecting data and storing the collected data. The second network function is configured for removing private information from the collected data and producing privatized data. The first and the second network functions are separately controlled and operated by different providers. The first network function is operated by a first provider via a first controller. The second network function is operated by a second provider via a second controller. The separately controlled feature of such a network architecture enhances data privacy by ensuring different entities control the collection of data and the privatization of the collected data.

摘要： Methods of location tracking and location resolution are discussed for network architectures which allow devices, such as User Equipment, to communicate with different networks (e.g., different network operators) without roaming. A hierarchical Connectivity Management (CM) is provided which allows for location tracking and location resolution as devices move within and between different network boundaries. Such a hierarchy includes a Global CM which provides inter network CM, and domain CM which provides intra network CM. Some embodiments utilize virtual user CMs within the domain. In some embodiments the global CM is implemented by a third party. In other embodiments different networks inter operate by utilizing virtual network slices over non-owned infrastructure to provide what appears to be a global network by each operator.
