Embodiment 1

[0106] Embodiment 1: The master node performs measurement configuration and measurement reporting path configuration

[0107] In the scenario of interoperability between LTE and NR in this embodiment, the LTE eNB is the primary node, and the NR gNB is the secondary node. The master node performs measurement configuration and measurement reporting path configuration for the terminal. The master node sends the measurement configuration information to the terminal, and sends the reporting path configuration information of the measurement report to the terminal. The terminal receives the measurement configuration information and the reporting path configuration information, obtains the corresponding configuration information and executes the corresponding configuration.

[0108] The mobility management method of this embodiment will be described below from the main node and the terminal side respectively.

Abstract

The invention provides a mobility management method, a network side device and a terminal. In the present invention, when a network performs measurement configuration of the terminal, the measurementreport path configuration is also configured for the terminal. According to the measurement configuration of the network, the terminal selects an appropriate path to perform the measurement uploadingof the network after the corresponding uploading condition is met, thereby solving a measurement problem in the LTE and NR interoperation scenarios. Through the reasonable path selection, the method ensures the measurement uploading through reasonable path selection, guarantees the delay and reliability of measurement uploading, optimizes network performance and enhances user experience.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a mobility management method, network side equipment and a terminal. Background technique [0002] With the development of mobile communication technology, research on 5G technology has become a hot topic today. In the early stage of 5G deployment, considering the existing deployment of the existing 4G network and the high frequency and small coverage characteristics of the 5G network itself, the joint networking of 4G and 5G is mainly used in the initial deployment. For example, LTE provides wide Domain coverage, new radio access technology (NR, New RAT) provides hotspot coverage. Therefore LTE and NR interoperability is an important technology. [0003] figure 1 It is a network scenario diagram in the case of LTE and NR interoperability, where the LTE base station (eNB) is the master node (MN, Master Node), and the NR base station (gNB) is the secondary ...
