In the description of the above embodiment, it is assumed that the first node migrates, but in an actual system, it may also be used when the first node does not migrate but the configuration is updated. In this way, the above first node and second node are nodes in the non-migration process. For example, the first node is the relay node, and the second node is the donor node or the central unit of the donor node, or the control plane part of the central unit of the donor node, or the user plane part of the central unit of the donor node.
Third Aspect: Data Packet Transmission
In the second aspect of the disclosure, the first node will be configured to transmit cached data packets according to the configuration before the configuration update or before the migration. However, in actual systems, these cached data packets are limited. After these cached data packets are transmitted, the configuration (the old configuration) before the configuration update or before the migration does not need to be retained. The “indication information for indicating to retain the configuration” contained in step 2-1 of the above second aspect provides a method for releasing the old configuration, that is, releasing the configuration by transmitting the first data configuration message.
