  • Patent number: 11963094
    Abstract: Systems, methods, and software for selecting a network slice for User Equipment (UE) based on a use case specified by the UE. In one embodiment, a slicing policy manager is implemented in a network that is partitioned into a plurality of network slices. The slicing policy manager receives a policy request for the UE, identifies a use case identifier in the policy request that indicates a use case specified by the UE, generates a use case slice selection policy configured to select a network slice from the plurality of network slices based on the use case specified by the UE, and initiates transmission of the use case slice selection policy to a slice selection manager. The slice selection manager may then select a network slice for the UE based on the policy.

  • Patent number: 10028161
    Abstract: A node increments values of performance measurement (PM) counters to indicate characteristics of at least one unlicensed frequency band used for wireless communication during a first time interval. The node provides the values of the PM counters to a controller that is configured to aggregate the values of the PM counters for the node with values of PM counters for other nodes. A controller receives values of PM counters from a plurality of nodes to indicate characteristics of wireless communication by each of the plurality of nodes using the at least one unlicensed frequency band over the first time interval. The controller aggregates the values of the PM counters for the plurality of nodes and modifies a configuration of at least one of the plurality of nodes based on the aggregated values.

  • Patent number: 9918232
    Abstract: A node in a wireless communication system includes a transceiver to receive one or more configuration parameters to configure the node for communication in an unlicensed frequency band. The node also includes a processor to implement a state machine that transitions, based on the one or more configuration parameters, between an enable state in which the node supports wireless connectivity in the unlicensed frequency band, a disable state in which the node does not support wireless connectivity in the unlicensed frequency band, and a flywheel state in which the node supports wireless connectivity in the unlicensed frequency band for a predetermined time interval before transitioning to the disable state.

  • Patent number: 8755805
    Abstract: At least one example embodiment discloses a method of generating a radio frequency (RF) map of a network. The method includes obtaining, by a controller, received signal strengths of at least one user equipment (UE) in a first technology network, determining, by the controller, a back projection of a second technology network based on the received signal strengths, and generating, by the controller, an RF map of the second technology network based on the determining. The back projection represents an attenuation function of a coverage area of the second technology network and the RF map illustrates the attenuation function of the coverage area of second technology network.
