METHOD FOR COORDINATION OF CONTROL PLANE TRAFFIC MANAGEMENT DURING DEVICE RECONFIGURATIONS AND RELATED APPARATUS

摘要

The present disclosure relates generally to communications, and more particularly to communication methods and related devices and nodes for control plane traffic management. Among other things, the disclosure presents a method performed by a central unit (CU) of a network node for coordination of control plane traffic management during a communication device reconfiguration in a telecommunications network. The method may, e.g., comprise receiving (1401) information from a distributed unit (DU) of the network node alerting the CU to reset a packet data convergence protocol (PDCP) sequence number of control plane traffic signaled from the communication device as a consequence of an event in the telecommunications network; and responsive to receiving the information, resetting (1403) the PDCP sequence number of the control plane traffic signaled from the communication device.
