A method is provided in one example embodiment and includes configuring on a network element a first tunnel from the network element to a first network, wherein the configuring comprises mapping a nexthop address of the local network element to a transport address of the tunnel on the network to create a first nexthop-to-transport mapping for the network element; and advertising the first nexthop-to-transport mapping along with routing information for the network element to remote network elements.

This application provides a policy determining method. The method includes: A first network element obtains first analytics information from a data analytics network element, where the first analytics information includes at least one of the following information: radio access type (RAT) related information or access frequency related information, and service experience analytics information corresponding to a RAT or an access frequency; and the first network element determines an access information selection policy of a terminal device based on the first analytics information, where the access information selection policy includes a target RAT or a target access frequency corresponding to the terminal device. The data analytics network element generates analytics information based on obtained network data and service data, and provides the analytics information for a network function network element.

A service server of a service provider issues an instruction for switching regarding a network slice to be applied to a user terminal.

The network-slice control server receives, from the service server of the service provider, the instruction for switching to the network slice to be applied to the user terminal. The network-slice control server transmits, to a subscriber management server, an instruction for changing subscriber information regarding the user terminal, on the basis of the instruction for switching to the network slice received from the service server. Thus, the subscriber information regarding the user terminal is changed in the subscriber management server.

Embodiments of the present invention disclose a communication method and a device. The method includes: determining a first CU-UP and a UPF network element that correspond to a QoS flow, where an access network device to which the first CU-UP belongs supports at least two CU-UPs; determining a first PDB for transmitting the QoS flow between the first CU-UP and the UPF network element; and sending the first PDB to the access network device, where the first PDB is used by the access network device to schedule an air interface resource. In the embodiments of the present invention, after the CU-UP corresponding to the QoS flow is determined, the PDB of the CU-UP corresponding to the QoS flow may be sent to the RAN device.

ISP-free methods, systems and products may include requesting, by a requester, the information from a source, and then passing, such as pushing or pulling, the information from the requester to a controller comprising a director and an optimizer. Further, the method may include receiving instructions from at least one directory, wherein each of the at least one directory is associated with at least one router in a plurality of routers. Further still, the method may include creating, by the optimizer in communication with the at least one directory, a routing plan for routing the information over at least a portion of the plurality of routers. And, yet further, the method may include directing, based on the creating and by the director in communication with the optimizer, placement of the information on one or more of the plurality of routers. Thereafter, routing may commence without connectivity from an ISP.

A SDN controller calculates forwarding paths for a traffic flow based on SDN technology. The controller determines a maximum flow rate and flow rate identify of each forwarding path, generates ingress flow table entries based on packet characteristic information of the traffic flow, the flow rate identify and an output port of an ingress node on each forwarding path, and sends the ingress flow table entries and maximum flow rate and flow rate identify to the ingress node; generates intermediate flow table entry for each intermediate node base on the packet characteristic information, flow rate identify and an and the output port of each intermediate node, and send each intermediate flow table entry to corresponding intermediate node; generates an egress flow table entry based on packet characteristic information and an output port of an egress node for sending the traffic flow, and sends the egress flow table entry to the egress node.

Some embodiments provide a method for implementing a software-defined private mobile network (SD-PMN) for an entity. At a physical location of the entity, the method deploys a first set of control plane components for the SD-PMN, the first set of control plane components including a security gateway, a user-plane function (UPF), an AMF (access and mobility management function), and an SMF (session management function). At an SD-WAN (software-defined wide area network) PoP (point of presence) belonging to a provider of the SD-PMN, the method deploys a second set of control plane components for the SD-PMN that includes a subscriber database that stores data associated with users of the SD-PMN. The method uses an SD-WAN edge router located at the physical location of the entity and a SD-WAN gateway located at the SD-WAN PoP to establish a connection from the physical location of the entity to the SD-WAN PoP.
