Abstract

Embodiments of the present disclosure relate to for inter-CU topology adaptation. A first device establishes a communication interface between the first device and a second device. The first device receives from the second device a handover complete message indicating that a handover of the second device from a third device to the first device is completed. The first device transmits to the second device a command indicating the second device to activate cells configured by the first device.

Claims (45)

1. A first device, comprising:

at least one processor; and

at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the first device to:

establish a communication interface between the first device and a second device;

receive from the second device a handover complete message indicating that a handover of the second device from a third device to the first device is completed; and

transmit to the second device a command indicating the second device to activate cells configured by the first device to serve at least one other fourth device, wherein the at least one other fourth device is served by the second device.

2. The first device of claim 1 , wherein the first device is caused to establish the communication interface by:

receiving a request for establishing the communication interface from the second device; and

transmitting a response indicating establishment of the communication interface to the second device.

3. The first device of claim 1 , wherein the first device is caused to transmit the command by:

transmitting a configuration update message comprising information concerning the cells.

4. The first device of claim 1 , wherein the first device is further caused to:

receive from the second device an indication indicating that a service status of the cells is In-Service.

5. The first device of claim 4 , wherein the first device is caused to receive the indication by:

receiving a configuration update acknowledge message comprising the indication.

6. A second device, comprising:

at least one processor; and

at least one memory including computer program code;

the at least one memory and the computer program code configured to, with the at least one processor, cause the second device to:

establish a communication interface between a first device and the second device;

perform a handover from a third device to the first device;

receive from the first device a command indicating the second device to activate cells configured by the first device; and

activate the cells based on the command, wherein the command is to serve at least one other fourth device, wherein the at least one other fourth device is served by the second device.

7. The second device of claim 6 , wherein the second device is caused to establish the communication interface by:

transmitting a request for establishing the communication interface to the first device; and

receiving from the first device a response indicating establishment of the communication interface.

8. The second device of claim 6 , wherein the second device is caused to receive the command by:

receiving a configuration update message comprising information concerning the cells.

9. The second device of claim 6 , wherein the second device is further caused to:

transmit to the first device an indication indicating that a service status of the cells is In-Service.

10. The second device of claim 9 , wherein the second device is caused to transmit the indication by:

transmitting a configuration update acknowledge message comprising the indication.

11. A method, comprising:

establishing, by a first device, a communication interface between the first device and a second device;

receiving from the second device a handover complete message indicating that a handover of the second device from a third device to the first device is completed; and

transmitting to the second device a command indicating the second device to activate cells configured by the first device to serve at least one other fourth device, wherein the at least one other fourth device is served by the second device.

12. The method of claim 11 , wherein the first device is caused to establish the communication interface by:

receiving a request for establishing the communication interface from the second device; and

transmitting a response indicating establishment of the communication interface to the second device.

13. The method of claim 11 , wherein the command is transmitted by:

transmitting a configuration update message comprising information concerning the cells.

14. The method of claim 11 , further comprising:

receive from the second device an indication indicating that a service status of the cells is In-Service.

15. The method of claim 14 , wherein the indication is received by:

receiving a configuration update acknowledge message comprising the indication.
