  • Patent number: 11121862
    Abstract: Wireless network specific (WN-specific) key can be used to provide access protection over the radio access link. A WN-specific key may be associated with (or assigned to) a wireless network, and distributed to access points of the wireless network, as well as to user equipments (UEs) following UE authentication. The WN-specific key is then used to encrypt/decrypt data transported over the radio access link. The WN-specific key can be used in conjunction with the UE-specific keys to provide multi-level access protection. In some embodiments, WN-specific kays are shared between neighboring wireless networks to reduce the frequency of key exchanges during handovers. Service-specific keys may be used to provide access protection to machine to machine (M2M) services. Group-specific keys may be used to provide access protection to traffic communicated between members of a private social network.

  • Publication number: 20210258246
    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.

  • Patent number: 11071020
    Abstract: Interference costs on virtual radio interfaces can be modeled as a function of loading in a wireless network to estimate changes in spectral efficiency and/or resource availability that would result from a provisioning decision. In one example, this modeling is achieved through cost functions that are developed from historical and/or simulated resource cost data corresponding to the wireless network. The cost data may include interference data, spectral efficiency data, and/or loading data for various links over a common period of time (e.g., a month, a year, etc.), and may be analyzed and/or consolidated to obtain correlations between interference costs and loading on the various links in the network. As an example, a cost function may specify an interference cost on one virtual link as a function of loading on one or more neighboring virtual links.

  • Publication number: 20210176322
    Abstract: Aspects of the disclosure provide a system and method used for allowing a path selection or reselection (hereby (re)selection). In some embodiments data packets for a session between a UE and an application system (AS) can utilize a pre-established user plane path between the AS and an access node (AN) which serves the UE. This can allow for faster session set-up times as a new user plane (UP) path need not be established for every new session if existing UP paths can be utilized. Some embodiments allow an application aware (re)selection of the user plane.
