Abstract

Embodiments of the present application provide a method and device for processing a secondary node cell change. The method includes: receiving indication information indicating that the PSCell change of the secondary node cell is completed, and obtaining the downlink tunnel endpoint identifier S1U-TEID of the first S1 user plane interface of the first terminal carried in the downlink data packet; according to a preset correspondence, Determine the Internet Protocol IP address of the first packet data convergence protocol PDCP corresponding to the first S1U-TEID; the IP address of the first PDCP is the IP address of the PDCP of the target cell where the first terminal performs PSCell change. The embodiments of the present invention solve the problems in the prior art that the PSCell change process consumes a lot of gNB tunnel resources and increases the signaling flow between the eNB and the core network.

Description

technical field [0001] The present application relates to the field of mobile communication technologies, and in particular, to a method and apparatus for processing a secondary node cell change. Background technique [0002] In the 5th Generation New Radio (5G NR) system of the fifth generation mobile communication technology, in order to achieve higher transmission rate and lower transmission delay, the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP) introduced dual connectivity (DUal Connectivity, DC) technology. DC technology means that a single user terminal (User Equipment, UE) can establish a communication link with two base stations at the same time, and perform uplink and downlink communication through dual communication links, so as to achieve higher data transmission rate and lower delay. Improve the performance of wireless communication systems. Compared with the single communication link, the dual communication link can make b...
