Methods for base-station-to-base-station connection management
First Claim
1. A method of operation of a base station in a cellular communication network, the method comprising:
- determining that the base station is transitioning to an unavailable state; and
notifying one or more radio network nodes that the base station is unavailable by sending a Stream Control Transmission Protocol message containing information indicating that the base station is unavailable;
wherein the Stream Control Transmission Protocol message is a Stream Control Transmission Protocol message with a Chunk Type set to “
Error”

Abstract
The present disclosure relates to a base station in a cellular communication network and methods of operation thereof. In one embodiment, a base station determines that the base station is transitioning to an unavailable state. The base station then notifies one or more radio network nodes with which the base station conducts base-station-to-node communication that the base station is unavailable. Thereafter, in one embodiment, the one or more radio network nodes cease communication attempts with the base station. In this manner, the radio network nodes can avoid spending additional resources on attempts to re-establish communication connections to base stations that tend to be offline more often (e.g., low-power base stations (LP-BSs)).

10. A method of operation of a base-station-to-base-station gateway in a cellular communication network, the method comprising:
-
determining that a first base station is unavailable; and notifying one or more second base stations with which the first base station conducts base-station-to-base-station communication that the first base station is unavailable by sending a Stream Control Transmission Protocol message containing information indicating that the first base station is unavailable; wherein the Stream Control Transmission Protocol message is a Stream Control Transmission Protocol message with a Chunk Type set to “

16. A method of operation of a base station in a cellular communication network, the method comprising:
-
receiving notification that a second base station is unavailable, the second base station being a second base station with which the base station conducts base-station-to-base-station communication by receiving a Stream Control Transmission Protocol message containing information indicating that the second base station is unavailable; and in response to receiving the notification, ceasing communication attempts with the second base station; wherein the Stream Control Transmission Protocol message is a Stream Control Transmission Protocol message with a Chunk Type set to “
Error”
