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: 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: An aspect of the disclosure provides a method for session admission at a node in an infrastructure provider network. The method includes receiving a connection request from a user equipment not associated with a network with which the infrastructure provider network is associated and obtaining from the user equipment, an identification of a service provider with which the infrastructure provider network is associated. Access authorization is then requested from the identified service provider. Embodiments allow such a process to provide government mandated free access, or for some other service provider to pay for the service.

摘要: According to embodiments, there is provided a method apparatus for determining an encoding scheme for transmission of encoded data across a communications channel. The method includes determining the encoding scheme at a design Signal-to-Noise Ratio and evaluating a Frame Error Rate of the encoding scheme. If the FER is not within a target range, the method further includes modifying the encoding scheme until the evaluated FER is within the target range. There is further provided a method and apparatus for mapping bit labels to a plurality of symbols in a constellation, wherein the constellation are organisable into a plurality of sets and each bit label includes a plurality of bit positions. The method includes determining a distance metric between sets and merging pairs of sets according to the distance metric. The method further includes assigning a value to a bit position for bit labels of symbols in the merged set.

摘要: An aspect of the disclosure provides a method of admitting a session from a user device subscribed to a service with a virtual network operator. The method includes receiving a service request from said user device at an Access Point and selecting a network function Authentication and Authorization (AA) function (AAF) to confirm the user device is authorized for the requested service, and transmitting the request to the selected network function AAA function. The AAAF which processes the request may reside with the virtual network operator (VNO). However, the VNO may share its AAA database with other network entities (for example, Telecom Connectivity Service Providers (TCSPs) or InPs), and allow those entities to perform the AAA functions.

摘要: A system and method is provided for mission critical communications. In an aspect, a computer-implemented method may be implemented for a node device on a network to facilitate communication between a sending device and an intended recipient device. The node device may receive from the sending device a mission critical (MC) communication directed to the intended recipient device. The node device may process the received MC communication to produce processed MC data and cache some or all of the processed MC data. The node device may transmit at least a portion of the received MC communication, the processed MC data, and/or the cached MC data to the intended recipient device.
