Problems solved by technology

[0003] However, when the IoT terminal device accesses the network device through the Relay UE, when the Relay UE fails in the process of switching from the current serving network device to the target network device; or, when the link between the Relay UE and the current serving network device When an interruption occurs, the Relay UE will enter an idle state on the cellular direct link, that is, the cellular direct link of the Relay UE will be unavailable, and IoT terminal devices will not be able to access the network through the Relay UE

Embodiment Construction

[0052] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0053] The terms "component", "module", "system" and the like are used in this specification to refer to a computer-related entity, hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and / or a computer. By way of illustration, both an application running on a computing device and the computing device can be components. One or more components can reside within a process and / or thread of execution and a component can be localized on one computer and / or distributed between two or more computers. In addition, these components can execute from various computer readable media having various data structures stored thereon. A comp...

Abstract

The embodiment of the invention provides information indication methods and devices. A method comprises the following steps: first terminal equipment determines first indication information accordingto a current link state between the first terminal equipment and network equipment, wherein the current link state is link reconfiguration failure, link switching failure, current switching, radio link failure or radio resource control connection reestablishment failure; and the first terminal equipment sends the first indication information to second terminal equipment, wherein the first indication information is used for notifying the current link state between the first terminal equipment and the network equipment to the second terminal equipment, and the first terminal equipment is the equipment capable of assisting the second terminal equipment to communicate with the network equipment. The second terminal equipment determines a coping policy according to the current link state between the first terminal equipment and the network equipment, so communication delay of the second terminal equipment is reduced, and communication efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of mobile communications, and more specifically, to a method and device for information indication in the field of mobile communications. Background technique [0002] Taking the mobile communication network as an example, in order to save the air interface resources of the network, most IoT terminal devices do not directly connect to network devices, but connect to them through another terminal device (such as a terminal device with relay function (Relay UE)). into the network device. By avoiding the direct long-distance communication between the IoT terminal device and the network device, the IoT terminal device is used to communicate with the Relay UE in a short distance, thereby saving the power consumption of the IoT terminal device. At the same time, the Internet of Things terminal device accesses the network device through the Relay UE (that is, does not directly connect to the network de...
