Embodiment 1

[0181] This embodiment provides an embodiment of D2D terminal handover in the first type of scenario, that is, two UEs are under one eNB before handover, and two UEs are under different eNBs after handover. This embodiment provides the procedure of D2D UE handover in the first type of scenario.

example 1

[0182] Example 1, the handover UE is the master UE, image 3 Schematic diagram of the switching process

[0183] D2D handover is divided into four parts: measurement object parameter adjustment, handover decision, handover preparation, and handover execution. Wherein, the measurement object parameter adjustment is an optional process, but the step of obtaining UE location in the measurement object parameter adjustment process is a necessary operation.

[0184] The measurement object parameter adjustment is a unique process of D2D handover, including the steps of obtaining the position of the UE and adjusting the measurement object parameters. The handover decision is a process between the eNB receiving the measurement report and judging that the UE can perform handover. The handover preparation is a flow from the original eNB sending a handover request message to receiving a handover request response message from the target eNB. The handover execution is a process from the ...

[0199] Instance 2, the handover UE is a slave UE, Figure 4 Schematic diagram of the switching process

[0200] D2D handover is divided into four parts: measurement object parameter adjustment, handover decision, handover preparation, and handover execution. Wherein, the adjustment of the measurement object parameters is an optional process, but acquiring the UE location is a necessary operation.

[0201] The measurement object parameter adjustment is a unique process of D2D handover, including the steps of acquiring the UE location and adjusting the measurement object parameters. The handover decision is a process from the eNB receiving the measurement report to judging that the UE can perform handover. The handover preparation is a flow from the original eNB sending a handover request message to receiving a handover request response message from the target eNB. The handover execution is a process from the source eNB sending a handover command to the UE accessing to the ta...

Abstract

Embodiments of the present invention disclose a terminal handover method, a communications node, a terminal, a system, and a storage medium. The terminal switching method comprises: a source communications node controlling, according to a measurement result reported by a first D2D terminal and/or information about a second D2D terminal, the first D2D terminal to be handed over to a target communications node.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular to a terminal handover method, a communication node, a D2D terminal and a system supporting a device-to-device (Device-to-Device, D2D) technology. Background technique [0002] At present, with the development of wireless multimedia services, people's demand for high data rate and user experience is increasing, thus putting forward higher requirements for the system capacity and coverage of traditional cellular networks. On the other hand, the popularity of applications such as social networking, short-distance data sharing, and local advertising has gradually increased people's demand for understanding and communicating with nearby interested people or things, that is, people's demand for proximity services (Proximity Services) Demand gradually increased. The traditional base station-centric cellular network has obvious limitations in terms of high data ra...
