Embodiment 1

[0217] This preferred embodiment provides a device mode switching method for a direct-to-device system, Figure 8 is a flow chart of a mode switching method according to a preferred embodiment of the present invention, such as Figure 8 As shown, the method includes step S802 and step S804.

[0218] Step S802: the first user equipment receives a mode switching message.

[0219] Step S804: The first user equipment performs mode switching according to the indication information included in the mode switching message.

[0220] Preferably, the modes include: a cellular communication mode, and a device-through communication mode.

[0221] Preferably, the mode switching includes two types: switching from the cellular communication mode to the D2D communication mode, and switching from the D2D communication mode to the cellular communication mode.

[0222] As a preferred implementation manner, before the first user equipment receives the mode switching message, it also includes: t...

Embodiment 2

[0330] Whether it is switching from cellular communication to D2D communication mode, or from D2D communication to cellular communication mode, the system requires that the user cannot perceive the mode switching during the mode switching process under the control of the network infrastructure to ensure service continuity. In view of the above requirements, the present invention proposes a device mode switching method of a D2D system. Specifically, such as figure 2 As shown, the first user equipment receives the mode switching message, and then the first user equipment performs mode switching according to the indication information included in the mode switching message. Through the method proposed by the present invention, the network infrastructure can require the user equipment to perform flexible switching between cellular communication and D2D communication modes according to the user equipment and its load conditions and ensure service continuity, thereby improving the ...

example 1

[0362] In the scenario covered by the network infrastructure, UE1 and UE2 have the capabilities of D2D discovery and D2D communication, and the D2D function is enabled. A data session communication is established between UE1 and UE2, and the data flow thereof is forwarded through the infrastructure of the cellular network. As UE1 gradually moves to the surrounding area of ​​UE2, UE1 can detect the discovery signal sent by UE2. As the distance between UE1 and UE2 gradually approaches, the measurement signal sent by UE2 detected by UE1 becomes stronger and stronger, exceeding the threshold set for measurement reporting, then UE1 sends a measurement report message to the serving base station eNB1. Figure 17 It is a flow chart of mode switching according to Example 1 of the embodiment of the present invention, such as Figure 17 shown, including the following steps:

[0363] Step S1702: UE2 sends a D2D discovery signal to UE1.

[0364]Step S1704: UE1 detects the D2D discovery ...

Abstract

The invention discloses a mode switching method and device. The method includes: a first base station transmits a mode switching message to first user equipment (UE) to drive the first UE to perform mode switching according to the mode instruction information carried in the mode switching information. By the method, the problem of poor service continuity caused by inflexible mode switching in the prior art is solved, and overall system throughput is increased.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a mode switching method and device. Background technique [0002] With the development of wireless multimedia services, people's demand for high data rate and user experience is increasing, which puts forward higher requirements on the system capacity and coverage of traditional cellular networks. On the other hand, the popularity of applications such as social networks, short-distance data sharing, and local advertisements has gradually increased people's demand for knowing and communicating with people or things of interest nearby (Proximity Services, Proximity Services). The traditional base station-centric cellular network has obvious limitations in terms of high data rate and proximity service support. In the context of this demand, D2D (Device-to-Device, device-to-device, which represents a new direction for future communication technology development) equipment) technol...
