摘要： Embodiments provide systems and methods for managing resources in networks which utilize network slicing. Embodiments include systems and methods for monitoring performance in networks which utilize network slicing when the resources of a network domain are allocated to more than one slice. Embodiments include systems and methods for monitoring performance when resources of a slice are controlled by different network operators/service providers. A domain manager can make the performance measurement data available per network allotment instance with an identifier indicating to which virtual network service the performance measurement data belongs.

摘要： A method of providing a network slice service includes a mobile network operator (MNO): providing one or more service profiles to a virtual service provider (VSP) serving a user population including a plurality of user devices, each service profile comprising attributes defining characteristics of a respective network slice service offered by the MNO, the network slice service comprising any one or more of: a Virtual Network with E2E service requirements; a Virtual Network with a specified network topology; and a virtualized infrastructure. The MNO receives a request for a selected network slice service from the VSP; determines whether or not the requested service can be provided; and responsive to determining that the requested service can be provided: sending a Service Level Agreement (SLA) for the network slice service to the VSP; and subsequently facilitating a network slice service instance in accordance with the SLA.

摘要： A method for providing a service in a telecommunications network comprising a plurality of resources and at least one slice of resources. The method comprises actions of receiving, creating and modifying. A request is received from a customer to serve a group of user devices by a first service. A new NSI is created to provide the first service, if it is determined that there is no existing NSI, shareable between a plurality of services, that can provide the first service. An existing NSI, shareable between a plurality of services, is modified to serve the group of user devices by that first service in addition to at least one second service that is already provided by the existing NSI, if it is determined that the existing NSI can provide the first service.

摘要： Methods and apparatus for determining whether to admit a virtual network using a set of communication network resources are provided. Different network resources can be owned by different infrastructure providers. Virtual network requests include a spatial profile of traffic requirements to be accommodated, and a determination is made as to whether the request can be accommodated based on available network resources. The resources include available backhaul link capacities. The resources can include computing resources for supporting service functions of the virtual network. Monitored network resource usage and traffic corresponding to the virtual network can be used to adjust future requests and accommodations. When a virtual network cannot be accommodated, a counter-offer can be made. Accommodation may incorporate monetary considerations. A feasibility computation of the admission procedure is formulated.

摘要： Methods for configuring user plane functions associated with a network slice. The methods include: creating a user plane configuration profile specific to at least one of an access technology and a user plane function; associating the user plane configuration profile with a network slice instance; selecting the network slice in response to a service request; and communicating the user plane configuration profile associated with the selected network slice instance to a control plane function.

摘要： A communication system and method for pre-fetching content to be delivered to User Equipment connected to a communication network is provided. The system and method may include at least one network entity operative to evaluate at least one network resource metric measuring an operating condition of the communication network, and operative to send to a UE connected to the network a pre-fetching message to trigger pre-fetching of the content.

摘要： A method and apparatus for deploying a set of network caches in a communication network is provided. A set of network nodes is identified such that, for each of a set of client device locations, and for at least a number c of the set of nodes, output of a coverage cost function is no greater than a threshold. The coverage cost function receives as input a client location and one of the nodes. The set of network caches are then located at the respective set of nodes. The set of network nodes can be selected from plural candidate sets based on a utility criterion. The candidate sets can be generated by successive addition and/or removal of nodes. Information obtained from a Traffic Engineering function can be used to direct selection of the set of nodes. A cache-client association can be generated for directing clients to particular caches.
