It should be noted that the time when the relay device sends the first indication information to the remote device is only related to the change time of the current link state, and is not directly related to the sending moment of the configuration information. The embodiment of the present application does not limit the sending time of the first indication information.

For example, after receiving the handover command sent by the serving base station and including multiple configuration information, the relay device switches from the current serving base station to the target base station. At this time, the relay device determines whether to send the first indication information to the remote device according to the link status with the network device.

For example, the relay device switches from the serving base station to the target base station after receiving the handover command including the multiple configuration information sent by the serving base station and after transmitting the configuration information to the remote device. At this time, the relay device may determine whether to send the first indication information to the remote device according to the current link state with the network device.

Establish failure information or RRC connection re-establishment failure information during non-link handover.

Specifically, the radio resource control connection re-establishment failure may be a radio resource control connection re-establishment failure in the link handover process, that is, the radio resource control connection re-establishment failure may be that the relay device is handed over from the original serving base station to the target base station. Failure, and failing to fall back to the original serving base station fails, that is, the radio resource control connection re-establishment failure of the relay device and the original serving base station fails; or the link reconfiguration failure may be wireless between the relay device and the original serving base station. The resource control connection re-establishment fails (ie, the relay device does not perform the link handover, but the link with the original serving base station is interrupted, and the reconnection with the original serving base station also fails).

Optionally, when the link state between the relay device and the network device is a link switch failure, the relay device determines, according to the current link state, that the first indication information is link switch failure information.

Specifically, when the relay device fails to perform the link handover (for example, the relay device fails to switch from the original serving base station to the target base station), the relay device determines the first indication information according to the current link state, and sends the first indication information to the remote device. Sending the first indication information, where the first indication information is used to indicate to the remote device that the current link state is a link handover failure, so that the remote device can obtain the handover failure information in time when the relay device fails to switch. , thereby rolling back to the original serving base station.

Optionally, when the link state between the relay device and the network device is being switched, the relay device determines that the first indication information is link switch information according to the current link state.

Specifically, when the relay device is performing link switching (for example, the relay device is switching from the original serving base station to the target base station), in order to prevent the remote device from transmitting data to the relay device during the link switching of the relay device The information is that the relay device sends the first indication information to the remote device, where the first indication information is used to indicate to the remote device that the data information is temporarily sent to the relay device.

S130. The remote device receives the first indication information sent by the relay device, where the first indication information is used to indicate a current link state between the relay device and the network device, where the current link state is a link reconfiguration failure. The second terminal device is a device capable of communicating with the network device via the first terminal device;

S140. The remote device determines, according to the first indication information, a current link state between the relay device and the network device.

It should be particularly noted that the relay side methods (S110 and S120) may be used alone or in combination with the remote side methods (S130 and S140). In addition, the remote side method may also be used separately. The embodiment is not limited.

Specifically, after receiving the first indication information sent by the relay device, the remote device may determine, according to the first indication information, a current link state of the relay device and the network device. That is, the relay device can know the current link state between the relay device and the network device in time according to the first indication information.

Optionally, when the first indication information is the link reconfiguration failure information, the remote device determines, according to the first indication information, that the link state between the first terminal device and the network device is a link reconfiguration. Failure status.

Specifically, after receiving the first indication information, when the first indication information is the link reconfiguration information, the remote device may determine, according to the first indication information, the relay device and the network device. The current link status is the link reconfiguration failure status. At this time, the remote device can perform reselection of the relay link (that is, the remote device reselects the relay device connected to the network device), or can directly establish a connection with the serving base station by using the direct link.

Optionally, when the current link state is a radio resource control (RRC) connection re-establishment failure, the relay terminal device determines, according to the current link state, that the first indication information is an RRC connection re-establishment. Failure information.

Optionally, when the first indication information is the link reconfiguration failure information, the link reconfiguration failure status includes a reconfiguration failure status in a link handover process or a reconfiguration failure status in a non-link handover process.

Specifically, when the first indication information received by the remote device is the link reconfiguration failure information, the remote device determines, according to the first indication information, that the current link state is a link reconfiguration failure state. Further, the remote device may determine, according to the first indication information, that the link state between the relay device and the network device is a link reconfiguration failure in the handover process; or determining that the current link state is in the non-link handover process. Reconfiguration failed.

For example, when the current link state is that the link reconfiguration fails during the handover, that is, the relay device fails to fall back to the original serving base station. At this time, when the remote device determines that the current link state is a link reconfiguration failure in the handover process, the remote device may reselect the relay device, or may establish a connection with the target base station by using the direct link.

Optionally, when the first indication information is the link switch failure information, the remote device determines, according to the first indication information, that the link state between the relay device and the network device is a link switch failure state.

Specifically, when the remote device receives the first indication information sent by the relay device, and the remote device determines, according to the first indication information, that the current link state is a link handover failure. At this time, the remote device can timely know the status of the current link according to the first indication information.

Optionally, when the first indication information is the link switching information, the remote device determines, according to the first indication information, that the link state between the first terminal device and the network device is in a switching state.

Specifically, after the remote device receives the first indication information sent by the relay device, the remote device determines, according to the first indication information, that the current link state is the handover state. At this time, the remote device determines to suspend sending data information to the relay device according to the indication of the first indication information, and waits for further indication by the relay device.

In the existing group switching technology, after the relay device receives the reconfiguration command sent by the serving base station and includes the configuration information, the relay device sends the configuration information to the remote device, and then the relay device completes from the serving base station. Handover of the target base station.

However, in the process of the relay device being switched from the serving base station to the target base station, there is a possibility that the handover fails (the relay device does not successfully access the target base station), and the relay device will return to the original serving base station. When the relay device fails to switch, at this time, the configuration information has been sent by the relay device to the remote device (the remote device has acquired the configuration information about the target base station), if the relay device does not give further instructions to the remote device. The remote device will work according to the configuration information of the target base station. Obviously, in the case that the relay device fails to switch, if the remote device continues to work according to the configuration information of the target base station, the remote device cannot complete the communication (due to the inconsistency in the configuration between the remote device and the base station).

In addition, when the relay device fails to switch, the relay device will fall back to the original serving base station. However, in the process of returning the relay device to the original serving base station, a fallback failure may also occur, and the relay device will enter an idle state. When the relay device fails to switch and the rollback fails (an example of radio resource control (RRC) connection re-establishment failure), if the relay device does not give further indication to the remote device, the remote device still selects the previous connection. The relay device communicates with the network device, but in reality, the remote device has been unable to communicate with the network device through the relay device (due to the fallback failure).

In another existing group switching technology, the relay device performs handover first, and after the relay device handover is completed, the relay device sends the configuration information to the remote device. This solution can solve the problems in the above existing group switching technology. However, another problem was introduced at the same time:

When the relay device makes a handover, the remote device does not know. Therefore, the remote device may send information to the relay device according to the configuration negotiated with the original serving base station.

However, at this time, the relay device is already performing handover, and during the handover process, the relay device will not send information to the base station (except for handover related signaling); when the relay device handover is completed, the relay device will follow The configuration negotiated with the target base station transmits information to the target base station. It does not make sense for the remote device to transmit information to the relay device according to the configuration negotiated with the original serving base station, and then forwarded by the relay device to the target base station.

Of course, in the existing group switching technology, even if the handover does not occur, there is a link failure between the relay device and the serving base station, and the radio resource control connection re-establishment fails. If the status is not timely notified to the remote device The remote device will continue to communicate with the network through the relay device, but in reality, the remote device cannot communicate with the network through the relay device.

On the other hand, according to the information indication method proposed by the embodiment of the present application, when the relay device fails to perform handover, link reconfiguration fails, is being switched, the radio link fails, or the radio resource control connection re-establishment fails, Transmitting, by the relay device, the first indication information to the remote device, where the first indication information is used to notify the remote device of the current link state between the relay device and the network device, so that the remote device according to the middle Determining the coping policy according to the current link state between the device and the network device (for example, the remote device determines whether to reselect the relay device or back to the original serving base station according to the current link state), thereby reducing the remote device Communication delays improve communication efficiency.
