Description

Information indication method and device

Technical Field

The embodiment of the invention relates to the field of mobile communication, and more particularly relates to a method and a device for information indication in the field of mobile communication.

Background

Taking a mobile communication network as an example, in order to save air interface resources of the network, most of terminal devices of the internet of things access the network device not directly, but through another terminal device (such as a terminal device (Relay UE) with a Relay function). The direct long-distance communication between the terminal equipment of the Internet of things and the network equipment is avoided, so that the terminal equipment of the Internet of things and the Relay UE are used for short-distance communication, and the power consumption of the terminal equipment of the Internet of things is saved. Meanwhile, the terminal equipment of the internet of things is accessed to the network equipment through the Relay UE (i.e. is not directly connected with the network equipment), so that the air interface connection required to be maintained by the network equipment is greatly reduced, and therefore, the terminal equipment of the internet of things is very beneficial to both air interface resources and processing resources of the network equipment.

However, when the Relay UE fails in the process of switching from the current service network device to the target network device in the process of accessing the network device by the Relay UE through the internet of things terminal device; or when the link between the Relay UE and the current service network device is interrupted, the Relay UE will enter an idle state on the cellular direct link, i.e. the cellular direct link of the Relay UE will not be available, and the terminal device of the internet of things will not be able to access the network through the Relay UE.

Disclosure of Invention

The embodiment of the invention provides an information indication method, which can support a second terminal device to determine a coping strategy according to a current link state between a first terminal device and a network device (for example, the second terminal device determines whether to reselect the first terminal device or fall back to an original service base station according to the current link state), so that the communication time delay of the second terminal device is reduced, and the communication efficiency is improved.

In one aspect, an embodiment of the present application provides a method for information indication. The method comprises the following steps: the first terminal equipment determines first indication information according to the current link state between the first terminal equipment and the network equipment, and sends the first indication information to the second terminal equipment, wherein the first indication information is used for informing the second terminal equipment of the current link state between the first terminal equipment and the network equipment. The current link state is a link reconfiguration failure, a link switching failure, a handover, a radio link failure or a radio resource control connection reestablishment failure, and the first terminal device is a device capable of assisting the second terminal device in communicating with the network device.

When the first terminal equipment has any one of the conditions of switching failure, link reconfiguration failure, switching, radio link failure or radio resource control connection reestablishment failure, the first indication information is sent to the second terminal equipment through the first terminal equipment, and the first indication information is used for informing the second terminal equipment of the current link state between the first terminal equipment and the network equipment, so that the second terminal equipment determines a coping strategy according to the current link state between the first terminal equipment and the network equipment (for example, the second terminal equipment determines whether to reselect the first terminal equipment or whether to fall back to the original service base station according to the current link state), thereby reducing the communication delay of the second terminal equipment and improving the communication efficiency.

In one possible design, the determining, by the first terminal device, the first indication information according to a current link state between the first terminal device and the network device includes: when the current link state between the first terminal equipment and the network equipment is link reconfiguration failure, the first terminal equipment determines that the first indication information is link reconfiguration failure information; or when the current link state between the first terminal equipment and the network equipment is link switching failure, the first terminal equipment determines that the first indication information is link switching failure information; or when the current link state between the first terminal device and the network device is switching, the first terminal device determines that the first indication information is link switching information; or when the current link state between the first terminal device and the network device is radio link failure, the first terminal device determines that the first indication information is radio link failure information; or when the current link state between the first terminal device and the network device is that the radio resource control connection re-establishment fails, the first terminal device determines that the first indication information is the radio resource control connection re-establishment failure information.

By having the first terminal device determine the first indication information corresponding to the current link state according to the current link state between the first terminal device and the network device, (i.e. the different first indication information represents the current different link state between the first terminal device and the network device). So that the second terminal device determines the current link state between the first terminal device and the network device according to the received different first indication information. The second terminal device is caused to determine a coping strategy according to the current link state between the first terminal device and the network device determined by the first indication information, for example, the second terminal device knows that the first terminal device is switching according to the first indication information, and then the second terminal device can stop sending data to the first terminal device. Also for example, if the second terminal device learns that the link between the first terminal device and the network device is unavailable (e.g., link reconfiguration failure, link handover failure, radio link failure, or radio resource control connection reestablishment failure) according to the first indication information, the second terminal device may perform reselection of the first terminal device to reduce a communication delay caused by reselection of the first terminal device when data transmission is required in the future, or the second terminal device may enter an idle state to avoid energy consumption caused by being in an active state.

In another aspect, an embodiment of the present application provides a method for information indication. The method comprises the following steps: the second terminal equipment receives first indication information sent by the first terminal equipment, and determines a current link state between the first terminal equipment and the network equipment according to the first indication information, wherein the first indication information is used for indicating the current link state between the first terminal equipment and the network equipment, the current link state is link reconfiguration failure, link switching failure, switching, radio link failure or radio resource control connection reestablishment failure, and the second terminal equipment is equipment capable of communicating with the network equipment through the first terminal equipment.

In one possible design, the determining, by the second terminal device, a current link state between the first terminal device and the network device according to the first indication information includes: when the first indication information is link reconfiguration failure information, the second terminal equipment determines that the current link state between the first terminal equipment and the network equipment is the link reconfiguration failure state according to the first indication information; or when the first indication information is link switching failure information, the second terminal equipment determines that the current link state between the first terminal equipment and the network equipment is the link switching failure state according to the first indication information; or when the first indication information is link switching information, the second terminal equipment determines that the current link state between the first terminal equipment and the network equipment is a switching state according to the first indication information; or when the first indication information is radio link failure information, the second terminal equipment determines that the current link state between the first terminal equipment and the network equipment is the radio link failure state according to the first indication information; or when the first indication information is the radio resource control connection reestablishment failure information, the second terminal equipment determines that the current link state between the first terminal equipment and the network equipment is the radio resource control connection reestablishment failure state according to the first indication information.

By having the first terminal device determine the first indication information corresponding to the current link state according to the current link state between the first terminal device and the network device, (i.e. the different first indication information represents the different current link state between the first terminal device and the network device). So that the second terminal device determines the current link state between the first terminal device and the network device according to the received different first indication information. Meanwhile, the second terminal device determines a coping strategy according to the current link state between the first terminal device and the network device determined by the first indication information, for example, the second terminal device knows that the first terminal device is switching according to the first indication information, and then the second terminal device can stop sending data to the first terminal device. For example, if the second terminal device learns that the link between the first terminal device and the network device is unavailable (for example, the link reconfiguration fails, the link switching fails, the radio link fails, or the radio resource control connection reestablishing fails) according to the first indication information, the second terminal device may timely perform reselection of the first terminal device, so as to reduce a communication delay caused by reselection of the first terminal device again when data transmission is required in the future, or the second terminal device may enter an idle state, so as to avoid energy consumption caused by being in an active state.

It should be noted that, before sending the configuration information to the remote device, the relay device may send first indication information to the remote device; or the relay device may transmit the first indication information to the remote device after transmitting the configuration information to the remote device.

It should be noted that, the time when the relay device transmits the first instruction information to the remote device is only related to the time when the current link state changes, and is not directly related to the transmission time of the configuration information. The embodiment of the invention does not limit the sending time of the first indication information at all.

For example, the relay device switches from the current serving base station to the target base station after receiving a switch command including a plurality of configuration information sent by the serving base station. At this time, the relay device determines whether to transmit the first indication information to the remote device according to the link state with the network device.

For example, the relay device may switch from the serving base station to the target base station after receiving a switch command including a plurality of configuration information sent by the serving base station and after sending the configuration information to the remote device. At this time, the relay device may determine whether to transmit the first indication information to the remote device according to the current link state with the network device.

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

Specifically, when a link reconfiguration failure occurs in a link between the relay device and the network device, the relay device determines, according to the current link state, first indication information as link reconfiguration failure information, and sends the first indication information to the remote device, where the first indication information is used to indicate the link reconfiguration failure between the relay device and the network device to the remote device.

Optionally, when the current link state is a radio link failure, the relay device determines that the first indication information is radio link failure information.

Optionally, when the current link state is a radio resource control (Radio Resource Control, RRC) connection reestablishment failure, the relay device determines, according to the current link state, that the first indication information is RRC connection reestablishment failure information.

Optionally, when the link state between the relay device and the network device is a radio resource control connection reestablishment failure, the radio resource control connection reestablishment failure information includes radio resource control connection reestablishment failure information in a link switching process or radio resource control connection reestablishment failure information in a non-link switching process.

Specifically, the radio resource control connection reestablishment failure may be a radio resource control connection reestablishment failure in a link switching process, that is, the radio resource control connection reestablishment failure may be a failure of switching the relay device from the original serving base station to the target base station, and a failure of backing back to the original serving base station, that is, a failure of reestablishing the radio resource control connection between the relay device and the original serving base station; or the link reconfiguration failure may be a radio resource control connection reestablishment failure between the relay device and the original serving base station (i.e., the relay device does not perform a handover of the link, but breaks the link with the original serving base station, and a 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 switching failure, the relay device determines that the first indication information is link switching failure information according to the current link state.

Specifically, when the relay device fails in link switching (for example, the relay device fails in switching from the original serving base station to the target base station), the relay device determines first indication information according to the current link state, and sends the first indication information to the remote device, where the first indication information is used to indicate to the remote device that the current link state is in link switching failure, so that the remote device can timely acquire the switching failure information when the relay device fails in switching, and thus fall back to the original serving base station.

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

Specifically, when the relay device is performing a link switch (e.g., the relay device is switching from an original serving base station to a target base station), in order to avoid the remote device from transmitting data information to the relay device during the link switch by the relay device, the relay device transmits first instruction information to the remote device for instructing suspension of transmission of the data information to the relay device to the remote device.

S130, the remote device receives first indication information sent by the relay device, wherein the first indication information is used for indicating the current link state between the relay device and the network device, the current link state is link reconfiguration failure, link switching failure, switching, radio link failure or radio resource control connection reestablishment failure, and the second terminal device is a device capable of communicating with the network device through the first terminal device;

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

It should be noted that the relay side method (S110 and S120) may be used alone or in combination with the remote side method (S130 and S140), and the remote side method may be used alone, which is not limited to the embodiment of the present invention.

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

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

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

Optionally, when the current link state is a radio resource control (Radio Resource Control, RRC) connection reestablishment failure, the relay terminal device determines, according to the current link state, that the first indication information is RRC connection reestablishment failure information.

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

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

For example, when the current link state is that the link reconfiguration in the handover process fails, 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 using the direct link.

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

Specifically, when the remote device receives the first indication information sent by the relay device, and according to the first indication information, the remote device determines that the current link state is the link switching failure. At this time, the remote device may timely learn, according to the first indication information, the state of the current link.

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

Specifically, after the remote device receives the first indication information sent by the relay device, the remote device determines that the current link state is the switching state according to the first indication information. 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 of the relay device.

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

However, in the process of switching the relay device from the serving base station to the target base station, there is a possibility that the switching 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), and if the relay device does not further instruct the remote device, the remote device operates according to the configuration information of the target base station. It is apparent that in case of handover failure of the relay device, if the remote device continues to operate according to the configuration information of the target base station, the remote device cannot complete communication (inconsistency occurs due to the configuration between the remote device and the base station).

In addition, when the relay device fails to switch, the relay device returns to the original service base station. However, during the process of the relay device backing up to the original serving base station, a failure of backing up may also occur, and the relay device will enter an idle state. When the relay device fails to switch and the fallback fails (an example of a radio resource control (Radio Resource Control, RRC) connection re-establishment failure), if the relay device does not indicate the remote device further, the remote device still selects the previously connected relay device to communicate with the network device, but in fact the remote device has failed 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 switching first, and after the switching of the relay device is completed, the relay device sends configuration information to the remote device. The scheme can solve the problems in the prior group switching technology. But at the same time introduces another problem:

when the relay device performs handover, the remote device is not known. Thus, the remote device may send information to the relay device in a configuration negotiated with the original serving base station.

However, at this point the relay device is already performing the handover, and during the handover the relay device will not send information to the base station (except for handover related signaling); when the relay device is switched, the relay device transmits information to the target base station according to the configuration negotiated with the target base station. The remote device does not have any meaning to send the information to the relay device according to the configuration negotiated with the original service base station, and then the information is forwarded to the target base station by the relay device.

Of course, in the conventional group switching technology, even if no switching occurs, there are cases where there is a link failure between the relay device and the serving base station and a radio resource control connection re-establishment failure, and if the above state is not timely notified to the remote device, the remote device also continues to communicate with the network through the relay device, but in reality, the remote device cannot communicate with the network through the relay device.

In contrast, according to the method for indicating information provided by the embodiment of the present invention, when any one of a handover failure, a link reconfiguration failure, a handover, a radio link failure or a radio resource control connection reestablishment failure occurs in a relay device, first indication information is sent to a remote device through the relay device, where the first indication information is used to notify the remote device of a current link state between the relay device and a network device, so that the remote device determines a coping strategy according to the current link state between the relay device and the network device (for example, the remote device determines whether to reselect the relay device or to fall back to an original serving base station according to the current link state), thereby reducing a communication delay of the remote device and improving a communication efficiency.

Fig. 3 shows a schematic flow chart of a method 200 of another example information indication according to an embodiment of the invention. As shown in fig. 3, the method 200 may include:

s210, the relay equipment measures the service base station and feeds back a measurement result to the service base station;

s220, the service base station sends switching request information to the target base station according to the measurement result;

s250, after receiving a switching command sent by a service base station, the relay equipment sends a reconfiguration command to the remote equipment;

S260, after the remote equipment completes reconfiguration, the remote equipment sends reconfiguration completion information to the relay equipment;

And S270, the relay device sends reconfiguration completion information to the service base station, wherein the relay device can send the reconfiguration completion information of each remote device to the service base station individually or send the reconfiguration completion information of each remote device and the relay device to the service base station uniformly.

Specifically, the relay device firstly measures the service base station, and feeds back the measurement result to the service base station after the measurement is completed; the service base station sends switching request information to the target base station according to the measurement result sent by the relay equipment; after receiving the switching request information sent by the service base station, the target base station sends a switching acceptance command to the service base station, wherein the switching acceptance command comprises a plurality of configuration information; after receiving the switching acceptance command, the service base station sends a switching command containing a plurality of configuration information to the relay equipment; then the relay equipment sends the reconfiguration information to the remote equipment; the remote equipment reconfigures according to the reconfiguration information, and after the reconfiguration is completed, the remote equipment sends reconfiguration completion information to the relay equipment; the relay device sends reconfiguration completion information to the serving base station, where the relay device may send reconfiguration completion information of each remote device to the serving base station separately, or send reconfiguration completion information of each remote device and the relay device to the serving base station in a unified manner.

It should be noted that this embodiment may be used as a single embodiment, or may be combined with an embodiment corresponding to the method 100, and the present application is not limited thereto as a new embodiment.

Specifically, the relay device may send the first indication information to the remote device before sending the configuration information to the remote device; or the relay device may transmit the first indication information to the remote device after transmitting the configuration information to the remote device.

For example, the relay device switches from the current serving base station to the target base station after receiving a switch command including a plurality of configuration information transmitted by the serving base station. At this time, the relay device determines whether to transmit the first indication information to the remote device according to the link state with the network device (i.e., according to whether the handover is successful).

Specifically, the network device determines indication information for indicating whether the remote device performs a group operation, and transmits the indication information for indicating whether the remote device performs a group operation to the relay device. That is, the indication information is used to instruct the remote device to perform a group operation; or the indication information is used for indicating that the remote equipment does not perform group operation; or the indication information is used for indicating whether the remote device performs group operation or not based on default configuration.

The network device may send indication information to the remote device; or the network equipment can send indication information to the relay equipment; or the network device sends the indication information to the relay device and the remote device at the same time.

Optionally, the network device sends the indication information to the remote device through the relay device.

For example, when the relay device receives the indication information sent by the network device, it is determined that only part of the indication information is information configured by the network device to the remote device, and at this time, the relay device sends only the part of the indication information to the remote device.

Optionally, the indication information is further used to indicate whether the relay device assists the remote device in performing group operations.

In particular, the indication information may indicate that the relay device assists the remote device in group operations. That is, the relay device assumes some or all of the operations between the remote device and the network device.

Optionally, the network device sends the indication information directly to the remote device, i.e. the network device does not send the indication information to the remote device via a relay device, but directly to the remote device via a link between the network device and the remote device.

The network device transmits the indication information, for example, over a cellular direct link between the base station and the remote device.

Alternatively, the indication information may indicate to a single remote device, or may indicate to some or all of the remote devices that establish a connection with the network device through the relay device. The embodiment of the present invention is not limited in any way.

Optionally, the group operation includes a group handover operation or a group tracking area update operation.

Alternatively, the indication information may indicate to a single remote device, may indicate to some remote devices, or may indicate to all remote devices that establish a connection with the network device through the relay device. The embodiment of the present invention is not limited in any way.

In existing group tracking area Update (TRACKING AREA Update, TAU) techniques, a relay device directly sends group TAU request information to a network device (i.e., the relay device sends group TAU request information to the network device regardless of whether the network device allows the relay device to perform a group tracking area Update), which is used to initiate a TAU request to the network device. However, the request information transmitted by the relay device is not necessarily passed by the network device, i.e., the network device may reject the request of the relay device. Thus, this solution lacks flexibility.

In contrast, according to the method for indicating information provided by the embodiment of the invention, the network device sends the indication information for indicating whether the remote device performs the group operation to the relay device and/or the remote device, so that before the relay device and/or the remote device send the group operation request to the network device, the relay device and/or the remote device agree on whether to send the group operation request information to the network device and the network device according to the indication information, invalid group operation request information is avoided from being sent to the network device, and meanwhile, in the case that the network device does not allow the relay device and/or the remote device to perform the group tracking area update, and the network device does not send feedback information to the relay device and/or the remote device (the network device loses the tracking area information of the relay device and/or the remote device), the difficulty that the network device subsequently performs paging to the relay device and/or the remote device is avoided.

and S420, the relay device and/or the remote device send the indication information to the network device, wherein the relay device is a device for assisting the remote device to communicate with the network device.

In particular, the relay device and/or the remote device may individually send indication information to the network device, the indication information being used to indicate that the remote device requests group operations. That is, by transmitting the instruction information to the network device, the group operation is requested to the network device.

The indication information may be sent by the remote device to the network device; or the indication information may be sent by the relay device to the network device; or the indication information may be sent to the network device by both the remote device and the relay device (i.e., the relay device sends a portion of the indication information to the network device and the remote device sends another portion of the first indication information to the network device).

Specifically, the determination of whether to pass the request of the remote device may be a determination of whether to allow the relay device to assist the remote device in performing the group operation.

It should be noted that, the embodiment of the present invention is described only by taking the example that the group operation includes the group handover operation or the group tracking area update operation, but the group operation may also include other operations, which is not limited by the embodiment of the present invention.

In the existing group Tracking Area Update (TAU) technology, the relay device sends request information to the network device, where the request information requests a group operation for all the remote devices connected to the network device through the relay device, however, the relay device is not authorized by the remote devices, that is, not all the remote devices wish to perform the group operation for all the remote devices connected to the network device through the relay device. Therefore, this solution also lacks flexibility.
