Description

Auxiliary cell group deletion method, terminal equipment and network node

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for deleting an auxiliary cell group, a terminal device, and a network node.

Background

In a 5G (5Generation, fifth Generation) mobile communication system, a terminal device, such as a UE (User Equipment), may adopt a DC (Dual Connectivity) architecture, which includes two Cell groups, namely, an MCG (Master Cell Group) corresponding to an MN (Master Node) on a network side and an SCG (Secondary Cell Group) corresponding to an SN (Secondary Node) on the network side. Specifically, the MCG includes a PCell (Primary Cell) and an SCell (Secondary Cell), the SCG includes a PSCell (Primary Secondary Cell) and an SCell, and the PCell and the PSCell may be collectively referred to as an SpCell (Special Cell).

Currently, the main process of UE conditional handover is: a source node sends switching request information to one or more target nodes; the target node feeds back switching confirmation information to the source node; a source node sends configuration information of condition switching to UE; UE evaluates whether the candidate cell meets the switching condition, and selects a target cell for switching after meeting the switching condition; UE initiates a random access process in the selected target cell; UE sends switching completion information to a target node; the source node sends a cancel condition switching command to other target nodes; and other target nodes send a conditional switch cancellation confirmation command to the source node.

In a DC architecture, a communication system often needs to deploy a large number of small cells and small base stations, and at this time, if an existing condition-based SCG deletion process is adopted, a large number of signaling configuration operations need to be performed, which causes signaling loss, and may not delete SCG cells timely and effectively, resulting in SCG failure and interrupted SCG data transmission.
