Abstract
The present application discloses a method and a device for managing a Pcell or a PScell, used to resolve the technical issue in the prior art of a lack of effective management in switching of a Pcell or a PScell in CU-DU architecture, and provides a timely and efficient strategy for switching a PScell, so as to improve communication system resource utilization efficiency. The method comprises: a CU determining a Pcell or a PScell of a UE; and the CU transmitting a Pcell/PScell change message to a DU, wherein the Pcell/PScell change message comprises a cell identifier of the cell required to be switched to the Pcell or the PScell, and the CU and the DU jointly serving the UE.

A method for managing a primary cell, Pcell, or a primary secondary cell, PScell, comprising:
- determining, by a central unit, CU, the Pcell or the PScell of a User Equipment, UE;
- and
- transmitting, by the CU, based on determining the Pcell or the PScell of the UE, a PCell/PScell change message to a distributed unit, DU, wherein the PCell/PScell change message comprises an identifier of a cell which needs to be switched to the Pcell or the PScell, and the CU and the DU jointly serve the UE.
A method for managing a primary cell, Pcell, or a primary secondary cell, PScell, comprising:
- determining, by a distributed unit, DU, a Pcell or a PScell of a User Equipment, UE;
- and
- generating, by the DU, based on determining the Pcell or the PScell of the UE, layer 2 configuration information, wherein the layer 2 configuration information comprises configuration parameter information required for a Pcell or PScell handover;
- and
- sending, by the DU, the layer 2 configuration information to a central unit, CU, wherein the CU and the DU jointly serve the UE.
A device for managing a primary cell, Pcell or a a primary secondary cell, PScell, comprising:
- a processor configured to:
- determine the Pcell or the PScell of a User Equipment, UE;
- and
- transmit, based on determining the Pcell or the PScell of the UE, a PCell/PScell change message to a distributed unit, DU, wherein the PCell/PScell change message comprises an identifier of a cell which needs to be switched to the Pcell or the PScell, and the device and the DU jointly serve the UE.
A device for managing a primary cell, Pcell or a primary secondary cell, PScell, comprising:
- a processor configured to:
- determine a Pcell or the PScell of a User Equipment, UE;
- and generate layer 2 configuration information, wherein the layer 2 configuration information comprises configuration parameter information required for a Pcell or PScell handover;
- and
- send, based on determining the Pcell or the PScell of the UE, the layer 2 configuration information to a central unit, CU, wherein the CU and distributed unit, DU, jointly serve the UE.
