An example controller device manages a plurality of network devices. The controller device includes one or more processing units, implemented using digital logic circuitry, configured to receive data representing a modification to unified intent model represented by a graph model, determine one or more vertices of the graph model affected by the data representing the modification and one or more vertices to be added to the graph model to extend the unified intent model, update the one or more vertices of the graph model affected by the data representing the modification and add the one or more vertices to be added to the graph model, compile the updated one or more vertices and the added one or more vertices to generate low level configuration data for the plurality of network devices, and configure one or more of the plurality of network devices with the low level configuration data.

A method and a system for maintaining session continuity, in which the system includes a Handover Source Function (HOSF), a Handover Destination Function (HODF), a Handover Anchor Function-Control Plane (HOAF-CP) and a Handover Anchor Function-User Plane (HOAF-UP). The method includes a first user establishing a connection through the HOSF with the HOAF-CP and the HOAF-UP which correspond to a second user, so as to establish a session with the second user. The method further includes that, during session handover, the HODF that corresponds to the HOSF establishing another connection with the HOAF-CP and HOAF-UP though which the first user continues the session with the second user, so as to maintain the session continuity. When access address or access technology of the terminal changes, or even the terminal changes during a session, the method and the system can logically replace the connection before the handover with a new connection to ensure the session continuity.

A method of data communication includes receiving, by a first wireless access gateway (WAG), at least a first data packet corresponding to a first data flow transmitted from user equipment (UE) and receiving, by a second WAG, at least a second data packet transmitted from the UE. In response to receiving the second data packet, the second WAG determines an identity of the first WAG, and in response to determining the identity of the first WAG, the method includes establishing a tunnel connection between the first WAG and the second WAG. After establishing the tunnel connection, the method includes receiving by the second WAG at least a third data packet corresponding to the first data flow transmitted from the UE, and the second WAG transmits to the first WAG, via the tunnel connection, the third data packet.

A method, performed by a first distributed unit (DU), of performing communication in a wireless communication system may include performing, based on resource usage of the first DU, configuration of an inter-DU interface with a second DU requiring a connection with the first DU, obtaining information about at least one first radio unit (RU) to be migrated to the second DU from among at least one RU connected to the first DU, stopping resource allocation for at least one uplink packet associated with at least one user equipment (UE) connected to the first RU, and transmitting, based on the configured inter-DU interface, to the second DU, at least one downlink packet required to be transmitted to the first RU or the at least one UE.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central unit (CU) may receive one or more cross-link interference (CLI) measurement reports that are based at least in part on one or more CLI measurements performed by one or more downstream nodes. The CU may transmit, and a distributed unit (DU) may receive, CLI measurement information based at least in part on the one or more CLI measurement reports. In some aspects, the DU may perform one or more CLI mitigation actions based at least in part on the CLI measurement information received from the CU. Numerous other aspects are provided.

Controller provides signals to controlled nodes and includes first channel interface coupled to first controlled node and second channel interface coupled to second controlled node. Controller discovers which channel interface is coupled to which controlled node by communicating first measurement request signal from first channel interface toward first controlled node; communicating second measurement request signal from second channel interface toward second controlled node; communicating power level request signal from a channel interface to first/second controlled nodes; receiving set of power levels from both first/second controlled nodes in response to power level request signal; determining that first controlled node is more strongly signal-coupled with first channel interface than second controlled node when first power level received from first controlled node is higher; and determine that second controlled node is more strongly signal-coupled with first channel interface than first controlled node when first power level received from second controlled node is higher.

A system described herein may register a particular radio access network (RAN)-based interface, such as a R1 interface, with a RAN, such as an Open-RAN (O-RAN). The system may further be associated with a particular Service-Based Interface (SBI) of a core network that includes a plurality of network functions (NFs), where each NF is associated with a respective SBI. The system may receive, via the particular SBI, a request for RAN information from one or more NFs of the core network, obtain the RAN information from the RAN via the particular interface, output the requested RAN information to the one or more NFs of the core network via the particular SBI. Associating the system with the SBI may be performed without modifying a Network Repository Function (NRF) of the core network.
