Samsung patents method for disconnecting smart controllers from cell towers

This patent describes a specific procedure for a smart controller in a wireless network to safely end its connection with a cell tower component. The process involves the tower sending a request to disconnect, the controller sending a confirmation, and then freeing up the digital resources used for that link.

Why it mattersThis is a routine technical update for managing connections in next-generation cellular networks, ensuring that software controllers and hardware towers can cleanly disconnect without leaving unused resources behind.

In the filing’s own words

A method performed by a near-Real Time (RT) Radio Access Network (RAN) Intelligent Controller (RIC) is provided. The method includes receiving, from an E2 node, an E2 removal request message for removing a connection between the near-RT RIC and the E2 node through an E2 interface, and transmitting, to the E2 node, an E2 removal response message through the E2 interface, in which the E2 node includes an O-RAN distributed unit (O-DU), an O-RAN central unit-control plane (O-CU-CP), an O-RAN central unit-user plane (O-CU-UP), or a base station that communicates with the near-RT RIC via the E2 interface, and the E2 interface provided for communication between the near-RT RIC and the E2 node supports an E2 application protocol (E2AP) for communication over the E2 interface.

What exactly they claim (claim 1)

1. A method performed by a near-real time (RT) radio access network (RAN) intelligent controller (RIC) in a wireless communication system, the method comprising: receiving, from an E2 node, an E2 removal request message for removing a signaling connection between the near-RT RIC and the E2 node through an E2 interface; transmitting, to the E2 node, an E2 removal response message through the E2 interface; and releasing at least one resource associated with removing of the signaling connection between the near-RT RIC and the E2 node, wherein the E2 node comprises an open radio access network (O-RAN) distributed unit (O-DU), an O-RAN central unit-control plane (O-CU-CP), an O-RAN central unit-user plane (O-CU-UP), or a base station that communicates with the near-RT RIC via the E2 interface, and wherein the E2 interface provided for communication between the near-RT RIC and the E2 node supports an E2 application protocol (E2AP) for communication over the E2 interface.
