Conditional full configuration and conditional delta configuration
A user device capable of receiving a full configuration related to a radio connection to a base station and a delta configuration which the user device can apply to a first configuration received previously (i) receives, from the base station while the user device is operating in a cell covered by the base station using the first configuration, the full configuration providing information for user device operation within a candidate cell ( 1404 ), (ii) determines whether a set of one or more conditions associated with the full configuration to the candidate cell is satisfied ( 1406 ), and (iii) connects to the candidate cell using the full configuration if the user device determines that the set of conditions is satisfied ( 1410 ).
1. A method in a base station capable of providing a full configuration related to a radio connection to a user device and a delta configuration which the user device can apply to a previously received configuration, the method comprising:
determining, by the base station and while the user device is operating in a cell covered by the base station using the previously received configuration, to configure the full configuration for the user device to connect to a candidate cell; and
transmitting, by the base station and to the user device, the full configuration and an indication of a set of one or more conditions that are associated with the full configuration for the user device to connect to the candidate cell and that are to be satisfied before the user device communicates with the base station via the candidate cell using the full configuration.
2. The method of claim 1 , wherein the base station is an MN connected with the user device operating in DC with the MN and an SN.
3. The method of claim 2 , wherein the determining comprises sending a request to a candidate SN, causing the candidate SN to generate the full configuration for configuring the candidate cell.
4. The method of claim 3 , wherein the transmitting further includes providing an indication of a second set of one or more conditions to be satisfied before the user device communicates with the candidate SN via the candidate cell using the full configuration.
5. The method of claim 4 , wherein transmitting the full configuration to the user device causes the user device to communicate with the candidate SN via the candidate cell if the user device detects a radio link failure (RLF) with the cell and the user device determines that the second set of one or more conditions are satisfied.
6. The method of claim 2 , wherein the determining comprises:
configuring a candidate SN for a conditional SN change, and
sending a request to the candidate SN, causing the candidate SN to determine to configure the full configuration for the user device.
7. The method of claim 1 , wherein the base station is an MN connected with the user device, and further configured to handover the user device to a candidate MN.
8. The method of claim 1 , wherein the base station is an MN connected with the user device, and further configured to handover the user device to the candidate cell.
9. A base station capable of providing a full configuration related to a radio connection to a user device and a delta configuration which the user device can apply to a previously received configuration, the base station comprising processing hardware configured to:
determine, while the user device is operating in a cell covered by the base station using the previously received configuration, to configure the full configuration for the user device to connect to a candidate cell; and
transmit, to the user device, the full configuration and an indication of a set of one or more conditions that are associated with the full configuration for the user device to connect to the candidate cell and that are to be satisfied before the user device communicates with the base station via the candidate cell using the full configuration.
10. The base station of claim 9 , wherein the base station is an MN connected with the user device operating in DC with the MN and an SN.
11. The base station of claim 10 , wherein the processing hardware is configured to determine to configure the full configuration for the user device by sending a request to a candidate SN, causing the candidate SN to generate the full configuration for configuring the candidate cell.
12. The base station of claim 11 , wherein the processing hardware is configured to transmit the full configuration and the indication by providing an indication of a set of one or more conditions to be satisfied before the user device communicates with the candidate SN via the candidate cell using the full configuration.
13. The base station of claim 10 , wherein the processing hardware is configured to determine to configure the full configuration for the user device by:
configuring a candidate SN for a conditional SN change, and
sending a request to the candidate SN, causing the candidate SN to determine to configure the full configuration for the user device.
14. The base station of claim 9 , wherein the base station is an MN connected with the user device, and further configured to handover the user device to a candidate MN.
15. The base station of claim 9 , wherein the base station is an MN connected with the user device, and further configured to handover the user device to the candidate cell.
16. A method in a user device capable of receiving a full configuration related to a radio connection to a base station and a delta configuration which the user device can apply to a first configuration received previously, the method comprising:
receiving, by the user device and from the base station while the user device is operating in a cell covered by the base station using the first configuration, the full configuration providing information for user device operation within a candidate cell; and
connecting, by the user device, to the candidate cell using the full configuration when the user device determines that a set of one or more conditions associated with the full configuration providing the information for the user device operation within the candidate cell is satisfied.
17. The method of claim 16 , further comprising:
detecting a radio link failure (RLF) with the cell;
in response to the detecting, determining that the set of one or more conditions associated with the full configuration providing the information for the user device operation within the candidate cell is satisfied; and
in response to the determining, communicating via the candidate cell.
18. The method of claim 17 , further comprising:
sending an indication of the detected RLF to the base station.
19. The method of claim 16 , wherein the base station is an MN connected with the user device operating in DC with the MN and an SN.
20. The method of claim 16 , wherein the user device communicates with a candidate SN via the candidate cell using the full configuration.
