摘要:
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.

Predicting mobile station migration between geographical locations of a wireless network can be achieved using a migration probability database. The database can be generated based on statistical information relating to the wireless network, such as historical migration patterns and associated mobility information (e.g., velocities, bin location, etc.). The migration probability database consolidates the statistical information into mobility prediction functions for estimating migration probabilities/trajectories based on dynamically reported mobility parameters. By example, mobility prediction functions can compute a likelihood that a mobile station will migrate between geographic regions based on a velocity of the mobile station. Accurate mobility prediction may improve resource provisioning efficiency during admission control and path selection, and can also be used to dynamically adjust handover margins.

There is provided methods, apparatus and systems for management and control of a communication network. The system includes a plurality of service providers, wherein each of the plurality of service providers belongs to a consortium and all the service providers in the consortium trust each other for actions under a rule corresponding to the consortium, wherein the rule indicates how to manage a record of the actions performed by each of the plurality of service providers. Each of the plurality of service providers is configured to provide a set of services in the communication network, wherein a set of services provided by one service provider in the consortium is in one service type and manage a creation of a record indicative of actions associated with a particular set of services that the service provider provides and a distribution of the record to one or more other service providers in the consortium.
摘要:
The present invention provides systems and methods and apparatuses for user plane handling. An aspect of the disclosure provides a method of user plane handling. Such a method includes sending, by a first user plane entity, to a second user plane entity, a trigger message for changing the user plane handling for a protocol data unit (PDU) session. Another aspect of the disclosure provides a method of using a shared tunnel. Such a method includes receiving from a reception tunnel by a first user plane entity a tunnel packet including a tunnel header and a data packet. Such a method further includes routing, by the first user plane entity to a second tunnel using information in the tunnel header without processing the data packet.
摘要:
Methods, systems and architectures are described which provide at least one aggregated tunnel protocol, in addition to the existing per PDU session tunnel protocols (1, 2,…N). When the UE requests a new PDU session or a new QoS flow, the SMF may establish a Per PDU Session Tunnel to serve this PDU session. Alternatively, an Aggregated Tunnel may be selected to serve the PDU session or to serve the QoS flow. When a packet from a UE arrives, the receiving network function can send this packet either using a per PDU session tunnel protocol or aggregated tunnel protocol.
摘要:
A method of providing telecommunication communication services to a customer, comprising, at a network management function (MF) of a telecommunication service provider: receiving an order in accordance with an agreement as to terms of a telecommunications service offering; accessing network resources that satisfy the terms of the service offering; initializing an instance of the service offering using the resources accessible thereby, creating at least one interface by which the telecommunications service offering is made available to the customer; and exposing each of the at least one created interfaces to enable a network MF of the customer to use the telecommunication service offering.

An aspect of the disclosure provides a method of network slice management performed by a Communication Service Management Function (CSMF). The method includes receiving service requirements and receiving capability exposure information. The method further includes transmitting network slice requirements in accordance with the service requirements and capability exposure information. In some embodiments the capability exposure information is received from a Network Slice Management Function (NSMF). In some embodiments the network slice requirements are transmitted to the NSMF. Other aspects are directed to methods implemented by an NSMF and a Network Sub-Slice Management Function (NSSMF). Other aspects are directed to the network functions themselves.
摘要:
Methods and apparatus for supporting customer charging in 5G networks are provided. Monitoring functions are instantiated at selected network locations for tracking access to network services. The monitoring functions provide charging information for use in customer billing. A customer can enter a service level agreement with a particular customized method of charging for service usage, and the monitoring functions can be customized to provide charging information according to the service level agreement. Charging can vary based on factors such as time of day, network congestion, service traffic characteristics, and geographic location. Charging can be reduced by a customer voluntarily reducing service quality, and/or if access is through a Wi-Fi network. Customers can dynamically control traffic to control charging. Charging rates under high-demand conditions can be negotiated via bidding. User-in-the-loop charging can be performed. Charging options for functions such as VNFaaS functions, data caching, pre-fetching, and context sharing are also provided.
