Self-configuration of donor/relay node relationship

摘要

The present invention relates to a method for transferring RAN configuration data between radio access nodes. In accordance with an embodiment of the invention, the method comprises the steps of, by a mobility management node (MMEA): receiving a first RAN configuration transfer message (1) issued by a source radio access node (eNBA) operating a source cell (A), comprising a target node identifier (RN-IDB) of a target relay node (RNB) operating a target cell (B) and a target tracking area identifier (TAIB) of the target cell, and whereby the source radio access node requests RAN configuration data from the target relay node; decoding the target node identifier and the target tracking area identifier; and in the event of the target tracking area identifier being managed by the mobility management node and the target node identifier being not associated with any registered radio access node, broadcasting said first RAN configuration transfer message towards a plurality of registered radio access nodes (DeNBC, eNBD) associated with the target tracking area identifier. The present invention also relates to a management mobility node.

1. A method for transferring Radio Access Network (RAN) configuration data between radio access nodes, and comprising, by a mobility management node:
receiving a first RAN configuration transfer message issued by a source radio access node operating a source cell, the first RAN configuration transfer message comprising a target node identifier of a target relay radio access node operating a target cell and a target tracking area identifier of said target cell, and whereby said source radio access node requests RAN configuration data from said target relay radio access node, decoding said target node identifier and said target tracking area identifier from said first RAN configuration transfer message, in the event of said target tracking area identifier being managed by said mobility management node and said target node identifier being not associated with a registered radio access node, broadcasting said first RAN configuration transfer message as a further first RAN configuration transfer message towards a plurality of registered radio access nodes associated with said target tracking area identifier, wherein the further first RAN configuration transfer message is configured for requesting from a donor radio access node Self Organizing Network configuration data in a further reply message.
