During the migration of the relay node, the donor node it accesses may change, which will cause the security configuration (such as the security key) of the user (that is, the user terminal UE) accessing the relay node to change. In traditional technology, once the central unit (the central unit of the donor node) to which the user is connected changes, all data packets that have not been transmitted to the user will be transmitted by using the new security configuration (such as a security key). However, in the relay network, since the relay node may still cache the data packets that use the old security configuration (before the relay node migrates), in order to allow the user to receive these data packets correctly (this may prevent the new donor node from retransmitting the data packets), the user needs to be configured so that the user may receive the data packets by using the correct security configuration. In order to achieve this objective, the above second aspect of the disclosure provides an optional method of delaying transmitting the RRC message to the user, and transmitting the “indication information for indicating to delay transmitting user configuration information” so that the second node may correctly receive the data packet. In addition to this optional method, the fourth aspect of the disclosure also provides other methods. In the following method, it is assumed that the donor node connected to the migrated node has migrated from one donor node (referred to as the source donor node) to another donor node (referred to as the target donor node). In this process, it is necessary to configure the users who access the migrated node.
For the above purpose, the fourth aspect of the disclosure provides a communication method, which may be executed by a sixth node, and the method includes:
