A method for performing a handover operation includes using one or more processors of a non-terrestrial node to initiate communication with a first terrestrial node of a network, the terrestrial node having a first unique node identifier and a cell identifier and store a mapping that associates the first unique node identifier with the cell identifier. The method also includes using the one or more processors to receive an indicator that the mapping is subject to change and update the mapping to associate a second unique node identifier of a second terrestrial node of the network with the cell identifier based on the received indicator.

A method for determining an application instance, an apparatus, and a system. The method includes: a first network element obtains location information of a terminal, determines first at least one MEC application instance based on the location information of the terminal, and sends address information of the first at least one MEC application instance to the terminal. This reduces a latency of packet transmission between an MEC application instance and the terminal and improves quality of services.

The disclosure relates to a 5G or pre-5G communication system for supporting a higher data rate after a 4G communication system such as LTE. A method according to an embodiment of the disclosure is a control method in an edge enabler server (EES) of a mobile edge computing system, and may include subscribing to a user plane path change event at an edge application server (EAS); determining an application context relocation (ACR) based on receiving a user plane path management event notification from the mobile communication network in case of subscribing to the user plane path change event for the EAS; transmitting an ACR request message to the EAS; receiving an EAS response message from the EAS; and transmitting an application function (AF) acknowledgment message to a first node of the mobile communication network in response to receiving the EAS response message from the EAS.

A session management function (SMF) receives, from a wireless device, time sensitive networking (TSN) bridge parameter comprising port information of a TSN bridge. The SMF sends, to a policy and charging function (PCF), a request for policy information, the request comprising the TSN bridge parameter. The SMF receives, from the PCF, a response to the request, the response comprising policy information for the wireless device.

A repeater system includes a first RF repeater device arranged in a first topology of a network of RF repeater devices, to communicate with one or more second RF repeater devices in the network of RF repeater devices to service one or more source nodes and destination nodes in a wireless network. The first RF repeater device deploys an intermediate frequency to frequency shift an incoming waveform. The first RF repeater device detects a change in a network condition in wireless network between one or more source node and the destination nodes. Based on the detected change in network condition, the one or more second RF repeater devices are controlled in network of RF repeater devices to re-configure the first topology of network of RF repeater devices to a second topology.

The technologies described herein are generally directed toward establishing a domain of authority for routing table updates from a routing device. According to an embodiment, a system can comprise a processor and a memory that can enable operations facilitating performance of operations including identifying a route update that comprises information about a network. According to the embodiment, the operations can further include communicating, via the network, the route update to a second routing device for propagation of the route update to routing devices in a first authority domain with the first routing device.

A wireless communication method used in a wireless communication device, wherein the wireless communication method includes the steps of: establishing a link with a first access point, and obtaining a backhaul SSID of a self-organizing network including the first access point from the first access point; referring to the backhaul SSID to obtain first access point information of the first access point and second access point information of a second access point within the self-organizing network, wherein each of the first access point information and the second access point information includes a BSSID; and selecting one of the first access point and the second access point to perform a wireless network connection according to the first access point information and the second access point information.

A forwarding entry generation method includes sending, by a controller, a plurality of resource allocation request messages to a plurality of network devices in a network slice, to trigger the plurality of network devices to allocate resources, where the resource allocation request message includes an identifier of the network slice and a resource that needs to be allocated by a corresponding network device to the network slice; receiving, by the controller, a plurality of resource allocation response messages including the identifier of the network slice and a segment identifier of a corresponding network device, and a resource allocated by each device belongs to the network slice; and generating, by the controller, a forwarding table corresponding to the network slice, where the forwarding table includes a forwarding entry for arriving at a network device in the network slice.

A routing method and apparatus for SDN-based LEO satellite network are disclosed. The LEO satellite network includes a control plane and a data plane. The control plane includes a central controller and a plurality of local controllers. The data plane includes a plurality of LEO satellite nodes and user terminals connecting to the LEO satellite nodes. The control plane may be located on the earth, and thus the centralized management and control of the data plane are placed on the earth. A local controllers monitors LEO satellite nodes in a subnet or subnets of the local controller. The distance between a local controller and a LEO satellite node is much smaller than the distance between a GEO satellite node and the LEO satellite node, and thus the time delay and the traffic loss of communication are reduced.

A software defined network controller receives from a radio access network access point an attach request generated by a user equipment that includes a user equipment identification and an IP address for the radio access network access point. The controller assigns a temporary identification to the user equipment and sends a modified attach request including the temporary identification, and application server identification and an application server IP address to the radio access network access point. The controller configures a forwarding table associated with the radio access network access point so that the access point forwarding table matches the user equipment identification, the application server identification and the application server IP address. The controller configures a service edge creation environment function forwarding table so that the forwarding table matches the user equipment identification mapped to the radio access network access point IP address.
