Embodiment 1

[0188] An embodiment of the present invention provides a path switching method, the method is applied to a first device, and the first device may specifically be a mobility management entity (Mobility Management Entity, MME), such as figure 1 As shown, the method includes:

[0189] 101. The first device determines to switch the direct communication path between the first user equipment and the second user equipment to a network communication path, and obtains a first identifier.

[0190] It should be noted that the direct communication path between the first user equipment and the second user equipment has a corresponding identifier. Wherein, the first identifier is used to identify a direct connection (direct connection) between the first user equipment and the second user equipment; or, the first identifier is used to identify the first user equipment and the second user equipment Direct communication (direct communication or direct one-to-one communication) between two use...

Embodiment 2

[0210] An embodiment of the present invention provides a path switching method, and the execution subject of the present invention is the first user equipment, such as figure 2 As shown, the method includes:

[0211] 201. The first user equipment sends a message to a third device, where the message carries a first identifier, and the message is used to let the third device know the signal strength corresponding to the first identifier, or to use the The first user equipment requests to switch the direct communication path between the first user equipment and the second user equipment to a network communication path, so that the third device determines to switch the direct communication path to the network communication path according to the message. network communication path.

[0212] Wherein, the first identifier is used to identify the direct connection between the first user equipment and the second user equipment; or, the first identifier is used to identify the connect...

Embodiment 3

[0225] An embodiment of the present invention provides a method for path switching, the method is applied to a fourth device, and the fourth device may be a server or a base station, such as image 3 As shown, the method includes:

Abstract

The present invention relates to the field of communications. Disclosed are a path switching method, device and user equipment (UE), capable of ensuring data transmission continuity between UEs communicating via a direct communication path (DCP) to improve user experience. The method comprises: a first UE sends a third device a message carrying a first identifier, the message being used by the third device to learn signal strength corresponding to the first identifier or used by a first UE to request switching the DCP between the first UE and a second UE to a network communication path to allow the third device to determine to switch the DCP to the network communication path according to the message; the first UE receives a message containing the first identifier sent by the third device to determine to switch the DCP to the network communication path according to the message.

Description

technical field [0001] The present invention relates to the communication field, in particular to a path switching method, device and user equipment. Background technique [0002] In a traditional mobile network, a data communication path between user equipments (User Equipment, UE) passes through a core network element serving gateway (Serving Gateway, SGW) and a packet data gateway (Packet Data Network Gateway, PGW). When data is transmitted between two UEs that are close to each other, it also needs to be transmitted through the core network. In this way, there is a large demand for the network transmission bandwidth of the core network, and the data transmission efficiency is low. [0003] In order to save the bandwidth of the core network and improve the transmission efficiency of short-distance UEs, in the prior art, for two short-distance UEs, they can negotiate according to the security key and establish a direct communication path (Direct Communication Path, DCP) fo...
