Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] Some of the terms involved in the embodiments of the present invention are explained below for easy understanding:

[0036] Dual Connectivity (DC): In 4G and 5G systems, the UE can use the DC (Dual Connectivity) architecture for data transmission. The existing common DC architecture is composed of two cell groups, the two cell groups are: Master Cell Group (Master Cell Group, MCG) and Secondary Cell Group (Secondary Cell Group, SCG), where MCG c...

Abstract

The embodiment of the invention provides a user equipment capability determination method and a node, relates to the technical field of communication, and is used for solving the problem that existingconventional switching UE maintains data connection at a source node and a target node at the same time. The method comprises the steps that in the switching preparation process, a target node receives first information from a source node, wherein the first information comprises at least one of the following information: second information and third information, the second information is used forindicating the available first UE capability allocated to a destination node by the source node in the dual-connection mode, and the third information is used for indicating all capabilities of the UE; and determining the available second UE capability of the destination node according to the first information. The present invention is applied to a scenario in which UE switches from a source nodeto a destination node.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and node for determining user equipment (User Equipment, UE) capabilities. Background technique [0002] In the 5G system, during the mobile process, the UE needs to meet the interruption delay of the mobility process of 0ms, that is, the UE needs to maintain the data connection between the source node and the target node during the process of moving from the source node to the destination node. , to send and receive data. [0003] However, since the existing conventional handover is a single connection handover, that is, during the normal handover process of the UE from the source node to the destination node, the UE needs to disconnect the data connection with the source node, then establish a data connection with the destination node, and There is no guarantee that the UE maintains a data connection at the source node and the target node at the s...
