Title:
DUAL/MULTI-CONNECTIVITY-BASED SECONDARY NODE ADDITION/REPLACEMENT METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/155936
Kind Code:
A1
Abstract:
The present application relates to the technical field of wireless communications, and disclosed are a dual/multi-connectivity-based secondary node (SN) addition/replacement method and device, for use in solving problems that in a dual/multi-connectivity scenario of a wireless communication, a process of adding or modifying an SN takes a long time and causes data transmission delay, and the probability of using dual-connectivity to transmit data is reduced because the establishment time of dual/multi-connectivity is too long. The method in the present application comprises: a user equipment receives configuration information of one/more SNs sent by a master node (MN); performing measurement assessment on the one/more SNs according to the configuration information of the one/more SNs to determining an SN satisfying a connectivity condition; and initiating a random access process to the SN satisfying the connectivity condition.
