Method and device for reducing interruption delay, and user equipment

Abstract

The invention discloses a method and device for reducing an interruption delay, and user equipment, used for solving the problem in the prior art that the overall running performance of the communication system is declined caused by the changes of network entities anchored by multi-connection user equipment. The method for reducing the interruption delay comprises the following steps that: a source main network entity of the source network side in the mobile communication network responds to an anchor point changing operation to initiate an anchor changing request to a target main network entity of the target network side; the target main network entity configures and obtains target network side configuration parameters based on the received anchor changing request; the source main networkentity receives the target network side configuration parameters and generates a wireless resource control message of the target network side based on the target network side configuration parameters; and after obtaining an anchor point reconstruction indication message generated and transmitted by the multi-connection user equipment based on the wireless resource control message, the target mainnetwork entity reconstructs the target network side when entering the effective state of the target network side configuration, so as to make the target main network entity become the target anchor point of the multi-connection user equipment, and ensure the seamless transfer of the user data.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of digital information transmission, and in particular to a method, device and user equipment for reducing interruption delay. Background technique [0002] A multi-connection user equipment refers to a user equipment that can connect to more than two network entities at the same time. In mobile communication networks, such as 2G, 2.5G, 3G, 4G, 5G or subsequent development of higher-generation mobile communication networks, when multi-connection user equipment moves to the overlapping signal coverage of two network entities, it will trigger Mobility access handover event. The existing multi-connection user equipment access switching method usually interrupts the user data transmission on the source network side first, and then continues the user data transmission after the multi-connection user equipment is switched to the target network entity. A technical problem that interrupts for...
