The present application will be described in further detail below with reference to the accompanying drawings.

Some terms provided in this application are explained below for the convenience of those skilled in the art to understand:

(1) Terminal equipment

Terminal equipment, also known as terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device that provides voice and/or data connectivity to users. devices, such as handheld devices with wireless connectivity, in-vehicle devices, etc. At present, some examples of terminals are: mobile phone (mobile phone), tablet computer, notebook computer, PDA, mobile internet device (MID), wearable device, virtual reality (virtual reality, VR) device, augmented reality (augmented reality, AR) equipment, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in smart grid, wireless terminals in transportation safety Wireless terminals, wireless terminals in smart cities, wireless terminals in smart homes, etc.

Specifically, the access node may be an evolved base station (evolutional Node B, referred to as eNB or eNodeB) in the LTE system, or a base station device (gNB), a small base station device, a wireless access node (WiFi AP), etc. in a 5G network. This embodiment of the present application does not limit this.

(3) Remote terminal equipment, relay terminal equipment

The relay terminal equipment (relay user equipment, Relay UE) provides the remote terminal equipment (remote user equipment, Remote UE) with communication to the operator network, and the remote terminal equipment can indirectly access the operator network through the relay terminal equipment. Among them, relay terminal equipment can also be called relay user equipment or relay UE; remote terminal equipment can also be called remote user equipment and remote UE; operator networks can deploy 5G base stations (generation NodeBs) based on 5G technology. gNB), 5G core network (5G core, 5GC) and data network (DN), 5G core network includes access and mobility management function (AMF). The communication between the remote UE and the relay UE is based on the PC5 interface, and the communication between the relay UE and the gNB is based on the Uu interface. When the relay UE and the remote UE are in the connected state, the relay UE transfers between the remote UE and the gNB ( or relay) information.

(4) Status of terminal equipment

The state of a terminal device (hereinafter referred to as UE) includes a connected state and a disconnected state, and the disconnected state is divided into an inactive (inactive) state and an idle (idle) state. For a UE, when the UE establishes a connection with the base station, which can be a direct connection or an indirect connection, the UE is in a connected state; when the connection between the UE and the base station is released, the UE is in a disconnected state, which can be in a deactivated state or idle state.

If the UE is in an idle state, both the UE and the base station will release the context information of the UE on the air interface. When the UE needs to re-establish a connection with the base station, the UE needs to re-establish a connection with the base station, and the base station needs to download the UE context from the core network side. .

If the UE is in a deactivated state, both the UE and the base station (or source base station) that previously established a connection with the UE will retain the context information of the UE on the air interface. When the UE needs to re-establish a connection with the base station, both the base station and the UE side can The connection is established using the pre-reserved UE context information. Compared with the UE being in an idle state to re-establish a connection with the base station, the process is shortened and the time is shorter. Specifically, the UE may initiate a request to the base station (or the target base station) to which the UE wants to establish a connection through a resume message, and the resume message carries the resume ID of the UE, so that the base station obtains the advance information according to the resume ID carried in the resume message. Retained contextual information, etc. The resume ID is sent by the source base station to the UE when the UE changes from the connected state to the deactivated state, and the resume ID is used to instruct the target base station to obtain context information through the source base station. Exemplarily, the aforementioned context information may include the following information:

fullI-RNTI: full Inactive RNTI (radio network temporary identity, wireless network temporary identity)

shortI-RNTI:shortI-RNTI

ran-PagingCycle:RAN(radio access network, wireless access network)

Paging Cycle

ran-NotificationAreaInfo: RAN notification area information

In addition, it should be understood that although the terms first, second, etc. may be used to describe various data in the embodiments of the present invention, these data should not be limited to these terms. These terms are only used to distinguish the various data from each other.

As shown in FIG. 1 , an embodiment of the present application provides a communication system architecture, where the communication system includes a first terminal device, a second terminal device, and a network device. Wherein, the first terminal device is indirectly connected (or referred to as indirect communication) with the network device through the second terminal device, and the second terminal device is directly connected (or referred to as direct communication) with the network device; the first terminal device may be the aforementioned remote terminal device, The second terminal device may be the aforementioned relay terminal device, and the network device may be a base station device in an operator network to which the relay terminal device is connected, such as a 5G base station (generation NodeB, gNB).

When the second terminal device needs to enter a non-connected state, or it needs to disconnect the connection between the second terminal device and the network device, or it needs to leave the network of the operator where the network device is no longer provided access to the network device for the first terminal device. During service, the state of the first terminal device can be processed in either of the following two ways.

The first type: the second terminal device first notifies the first terminal device that the second terminal device needs to enter the disconnected state, and the first terminal device actively requests the target state of the first terminal device.

The second type: the second terminal device first initiates a request to enter the disconnected state to the network device, and the network device determines the state of the first terminal device by itself or determines the target state of the first terminal device in combination with the relevant requirements of the first terminal device.

Embodiments of the present application provide a state indication method and a communication apparatus for a terminal device, which can be applied to the communication system illustrated in FIG. 1 . When the second terminal device (relay terminal device) needs to enter the disconnected state, the state of the first terminal device (remote terminal device) is indicated to complete the processing of the state of the first terminal device. Since the principles of the method and the device for solving the problem are the same, the method part and the device part of the embodiments can be referred to each other, and the repeated parts will not be repeated.

The state indication method of the terminal device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

For the aforementioned first method of processing the state of the first terminal device, the first terminal device can actively request the target state of the first terminal device from the network device through the second terminal device, and then the network device sends the first terminal device through the second terminal device to the network device. The device indicates the target state of the first terminal.

As shown in FIG. 2 , an embodiment of the present application provides a first method for indicating a state of a terminal state, and the method is as follows.

S201, the second terminal device determines that it needs to enter a disconnected state.

Wherein, the second terminal device is a relay terminal device, and the second terminal device may determine that it needs to enter a disconnected state when the operator network needs to be switched or there is no local data transmission.

Exemplarily, if the second terminal device is a dual-card single-pass mobile phone and other terminal devices, when switching from one card (referred to as card 1) to another card (referred to as card 2) to perform services such as making calls, it needs to be Put card 1 into a disconnected state (idle state or deactivated state). For another example, when the second terminal device does not transmit data locally, the second terminal device may enter a disconnected state (idle state or deactivated state) to save power consumption.

S202, the second terminal device sends a first message to the first terminal device, where the first message is used to indicate that the second terminal device needs to enter a disconnected state.

Wherein, the first terminal device is in a connected state and the first terminal device communicates with the network device through the second terminal device; the first terminal device is a remote terminal device. The first message may be a leave request, and the second terminal device indicates that the second terminal device is about to leave by sending a leave request to the first terminal device, so as to indicate that the second terminal device needs to enter a disconnected state.

S203, the first terminal device requests a target state of the first terminal device from the network device through the second terminal device.

In an optional implementation manner, the first terminal device may send first request information to the network device through the second terminal device, where the first request information is used to request the target state of the first terminal device, and the The target state can be a connected state, a disconnected state, or an idle/deactivated state in a disconnected state. If the first terminal device has a target state that the first terminal device wants to enter, the information used to indicate the target state that the first terminal device wants to enter may be included in the first request information. For example, the first request information includes a state identifier, and the state identifier is used for Indicate the target state that the first terminal device wishes to enter; or, if the first terminal device does not have a target state that it wishes to enter, but only requests the network device to indicate a target state, the aforementioned state identifier may not be included in the first request information.

The state identifier included in the first request information may be a target state that the first terminal device wants to enter, or an index that can represent the target state that the first terminal device wants to enter. Exemplarily, the index of the connected state is 0, the index of the idle state in the disconnected state is 1, and the index of the deactivated state in the disconnected state is 2. If the target state that the first terminal device wishes to enter is the connection state in the connection state, the state identifier included in the first request information may be the connection state/connection, or may be "0"; if the first terminal device wishes to enter the connection state If the target state is the idle state in the disconnected state, the state identifier included in the first request information may be idle state/idle, or "1"; if the target state that the first terminal device wants to enter is in the disconnected state Inactive state, the state identifier included in the first request information may be inactive state/inactive, or it may be "2"; if the target state that the first terminal device wants to enter is only the disconnected state, then the first request The state identifiers contained in the information may include idle state/idle, deactivated state/inactive, and may also include "1" and "2". In addition, a bit sequence can also be used to represent the index of the target state. For example, based on two bits, the index of the connected state is "00", the index of the idle state in the disconnected state is "01", and the index of the disconnected state is "01". The index of the active state is "10".

During specific implementation, the first request information may be carried in UE assistance information (UE Assistance information) sent by the first terminal device and sent to the network device. Exemplarily, the first request information may be the preferredRRC-State-r16 field defined in ReleasePreference-r16 in the UE assistance information sent by the first terminal device; the value of the preferredRRC-State-r16 field is null or the aforementioned state identifier, When the value of the preferredRRC-State-r16 field is empty, it indicates that the first terminal device does not have a target state that the first terminal device wishes to enter.

In another optional implementation manner, the first terminal device may send a second message to the second terminal device, where the second message is used to instruct the first terminal device to confirm that the second terminal device needs to enter the disconnected state. Optionally, the second message includes information used to indicate the target state that the first terminal wishes to enter, indicating that the first terminal device has a target state that is expected to enter; or, the second message does not include information used to indicate that the first terminal wishes to enter. The information of the entered target state indicates that the first terminal device does not have a desired target state to enter. Optionally, the corresponding first message is a leave request, and the second message may be a leave response, indicating that the first terminal device confirms the leave request of the second terminal device, that is, it knows that the second terminal device is about to leave.

The second terminal device sends the first request information to the network device according to the second message. Wherein, if the second message includes information for indicating the target state that the first terminal wishes to enter, the first request information includes a state identifier; the second message does not include information for indicating the target state that the first terminal wishes to enter , the first request information does not contain a state identifier.

During specific implementation, the first request information may be carried in UE assistance information (UE Assistance information) sent by the second terminal device and sent to the network device, and the first request information may be new information in the UE assistance information sent by the second terminal device. Added definition. Exemplarily, the first request information is a newly defined remoteID-preferredRRC-State-r16 field in ReleasePreference-r16 in the UE assistance information sent by the second terminal device.

Wherein, the value of the remoteID-preferredRRC-State-r16 field is null or the aforementioned state identifier, and when the value of the remoteID-preferredRRC-State-r16 field is null, it indicates that the first terminal device has no target state that the first terminal device wishes to enter. The remoteID is used to identify the first terminal device, and may be an identifier of the first terminal device. In addition, it should be noted that "remoteID-preferredRRC-State-r16" is only used as an indication of a field name, and other field names can also be set in the UE auxiliary information sent by the second terminal device to indicate the first request information, This embodiment of the present application does not limit this.

S204, the network device indicates the target state of the first terminal device to the first terminal device through the second terminal device.

The target state indicated to the first terminal device may be one of a deactivated state, an idle state, and a connected state. Optionally, the network device may determine the target state indicated by the first indication information based on whether the received first request information includes a state identifier. For example, in the case where the first request information received by the network device does not contain a status identifier, the network device may take into account actual needs such as whether the first terminal device has data to be sent, whether the relevant network service involves the first terminal device, etc. to determine the target state indicated to the first terminal device. For another example, in the case where the first request information received by the network device includes a state identifier, the network device may determine the target of the first terminal device indicated to the first terminal device according to the state identifier in the first request information The state, that is, the target state indicated to the first terminal device is consistent with the target state that the first terminal device wants to enter. In addition, the network device can also obtain the target state of the second terminal device, and set the target state indicated to the first terminal device to be the same as the target state of the second terminal device.

During specific implementation, the network device may send a connection release message carrying first indication information to the first terminal device through the second terminal device, where the first indication information is used to indicate the target state of the first terminal device. Optionally, if the first indication information contains context information, the target state indicated by the first indication information is a deactivated state; if the first indication information does not contain context information, then the target state indicated by the first indication information is a deactivated state; The target state is the idle state. The connection release message may specifically be implemented by using a radio resource control connection release (radio resource control connection release, RRC Connection Release) message.

Alternatively, the network device may send a connection reconfiguration message to the first terminal device through the second terminal device to indicate that the target state of the first terminal device is the connected state. Optionally, the connection reconfiguration message may be specifically implemented by a radio resource control connection reconfiguration (radio resource connection reconfiguration, RRC Connection Reconfiguration) message.

In the embodiment of the present application, the second terminal device first notifies the first terminal device that it needs to enter the disconnected state, triggering the first terminal device to actively initiate a request for the target state, and the network device sends the target state based on the request of the first terminal device Instructing the first terminal device can prevent the second terminal device from entering the disconnected state from affecting the services of the first terminal device, for example, instructing the first terminal device to remain in the connected state to prevent the second terminal device from entering the disconnected state. The first terminal equipment of data transmission is affected; the deactivation state is indicated to the first terminal equipment, which can avoid causing excessive delay to subsequent reconnection; the idle state is indicated to the first terminal equipment, so that the first terminal equipment is more efficient. Quickly enter the idle state to avoid resource waste caused by the first terminal device not changing the state in time when the second terminal device enters the non-connected state.

Further, before S203, it also includes the first terminal device determining whether it has a target state that it wants to enter; and if the result is yes, determining the target state that the first terminal device wants to enter. Optionally, the first terminal device may determine the target state that the first terminal device wants to enter according to the first message sent by the second terminal device in S202 and/or whether the first terminal device has data to be sent. The first message sent by the second terminal device carries information used to indicate the target state to be entered by the second terminal device, and the target state to be entered by the second terminal device is one of an idle state and a deactivated state . The second terminal device specifically informs the first terminal device whether the second terminal device needs to enter the idle state in the disconnected state or the deactivated state in the disconnected state by sending the first message carrying the first message to the first terminal device.

During specific implementation, the target state that the first terminal device wishes to enter may be determined by reference to the following method: if the first terminal device determines that there is no data to be sent, that is, it may not remain in the connected state, the first terminal device may determine that it wishes to enter the target state. The target state is a disconnected state. Specifically, the first terminal device can determine whether the target state it wants to enter is an idle state or a deactivated state according to whether subsequent reconnection is required; or, the first terminal device can determine the desired state. The target state is consistent with the target state indicated in the first message that the second terminal device needs to enter. If the first terminal device determines that data is to be sent, it determines that it still wishes to remain in the connected state.

Based on this, in the case where the first request information includes a state identifier, that is, when the first terminal device determines the target state it wishes to enter, the target state indicated by the first indication information sent by the network device in S304 may refer to the following methods 1 to Three ways to determine:

Mode 1: If the first request information requests the target state of the first terminal device to be a disconnected state, but does not specify whether the idle state or the deactivated state, the network device may indicate one of the idle state and the deactivated state to the first terminal device. , for example: the network device can obtain the state to be entered by the second terminal device, and indicate the state to be entered by the second terminal device as the target state of the first terminal device to the first terminal device;

Mode 2: If the first request information requests the target state of the first terminal device to be in the disconnected state and the idle state, the network device indicates the idle state to the first terminal device; if the first request information requests the target state of the first terminal device If the state is the disconnected state and the deactivated state, the network device indicates the deactivated state to the first terminal device.

Specifically, the network device may include context information in the first indication information, indicating that the network device indicates the deactivated state to the first terminal device, and can provide context information for the first terminal device to subsequently restore the connection state; that is, the first indication information is used for to indicate that the target state of the first terminal device is the deactivated state. The network device may also not include context information in the first indication information, indicating that the network device indicates the idle state to the first terminal device; that is, the first indication information is used to indicate that the target state of the first terminal device is the idle state.

Mode 3: If the target state of the first terminal device requested by the first request information is the connected state, the network device may indicate the connected state to the first terminal device, that is, the first indication information is used to indicate the target of the first terminal device The state is connected.

Further, after the first terminal device receives the first message in the aforementioned S202, if the first terminal device determines that the connection state needs to be maintained, the first terminal device may also send a path switching request to the network device through the second terminal device, and the path switching The request is used to request the first terminal device to keep the connection state. The network device determines a target network device that can communicate with the first terminal device and provides services for the first terminal device, and sends a connection reconfiguration message to the first terminal device through the second terminal device to instruct the first terminal device to establish a connection to the target network device. The connection reconfiguration message may include configuration information of the target network device, and the configuration information of the target network device includes the identifier of the target network device and the wireless resources allocated by the target network device to the first terminal device. Optionally, the target network device may be pre-configured, or the network device may send the measurement configuration to the first terminal device, and receive the measurement configuration determined by the measurement report sent by the first terminal device when it is determined that the connection state needs to be maintained. .

On the basis of FIG. 2 , referring to FIG. 3 , an embodiment of the present application provides a second method for indicating the status of a terminal device, and the method is as follows.

S301, the second terminal device determines that it needs to enter a disconnected state.

S302, the second terminal device sends a leave request to the first terminal device, where the leave request is used to indicate that the second terminal device needs to enter a disconnected state. The first terminal device is in a connected state and the first terminal device communicates with the network device through the second terminal device.

S303, the first terminal device sends the UE auxiliary information to the network device through the second terminal device, that is, the second terminal device relays the UE auxiliary information sent by the first terminal device to the network device.

The UE auxiliary information carries first request information, and the first request information is used to request a target state of the first terminal device, and the target state may be a disconnected state, or a deactivated state or an idle state in the disconnected state ; The UE assistance information sent by the first terminal device is a message exchanged between the first terminal device and the network device. Of course, the UE assistance information sent by the first terminal device may also be other messages, as long as it carries the first request information, which is not limited.

Optionally, the first request information includes a cause value (cause), where the cause value is used to indicate that the second terminal device needs to enter the disconnected state. S303 in FIG. 3 specifically illustrates that the first request information carried in the UE auxiliary information sent by the first terminal device includes a reason value: relay leave.

When receiving the UE assistance information carrying the cause value from the first terminal device, the network device can determine, based on the aforementioned cause value, that the first terminal device requests its target state because the second terminal device needs to enter the disconnected state. Do not release or reserve the first resource in the second terminal device, the first resource is the resource required by the second terminal device to provide a relay service for the first terminal device, and the first resource is used by the second terminal device to The information from the first terminal device is sent to the network device, or the first resource is used for the information received by the second terminal device from the network device to be sent to the first terminal device; instead, it waits for the second terminal device to initiate a related request to enter the disconnected state , the first resource and the second resource in the second terminal device are released at one time, and the second resource is the resource required by the second terminal device to communicate with the network device. The resource processing flow for the second terminal device can be simplified, and the signaling overhead can be reduced.

Specifically, FIG. 3 illustrates that after receiving the UE assistance information sent by the first terminal device in S303, the network device temporarily reserves the first resource in the second terminal device; waiting for receiving the UE assistance information sent by the second terminal device in S306 After the UE assists the information, the first resource and the second resource in the second terminal device are released. Optionally, the aforementioned first resource and second resource are pre-configured by the network device in the second terminal device.

S304, the network device sends a connection release message to the first terminal device through the second terminal device, where the connection release message carries first indication information, where the first indication information is used to indicate a target state of the first terminal device, and the target state is idle One of the state and the deactivated state.

Optionally, if the first indication information in the connection release message includes context information, the first indication information is specifically used to indicate that the target state of the first terminal device is the deactivated state, and after the first terminal device receives the connection release message, , switch from the connected state to the deactivated state based on the context information contained in the first indication information; if the first indication information in the connection release message does not contain context information, the first indication information is specifically used to indicate the target of the first terminal device The state is the idle state, and the first terminal device switches from the connected state to the idle state after receiving the connection release message.

During specific implementation, the connection release message sent by the network device to the first terminal device may be implemented by using an RRC Connection Release message. Exemplarily, the first indication information may be SuspendConfig in the RRC Connection Release message sent by the network device to the first terminal device; wherein, if the SuspendConfig contains context information, it indicates the target state of the first terminal device indicated by it. In the deactivated state; if the context information is not included in the SuspendConfig, it indicates that the target state of the first terminal device indicated by the SuspendConfig is in the deactivated state.

In addition, it should be noted that the connection release message sent by the network device in S304 to the first terminal device may also be other messages, as long as it carries the first indication information, which is not limited.

S305: After the first terminal device enters the target state indicated by the first indication information, it sends a leave response to the second terminal device.

The leaving response is used to instruct the first terminal device to confirm that the second terminal device needs to enter the disconnected state, and the leaving response is also used to instruct the first terminal device to enter the target state indicated by the first indication information. Then, the second terminal device may determine that the first terminal device enters the target state according to the leaving response.

S306, the second terminal device sends UE auxiliary information to the network device, the UE auxiliary information sent by the second terminal device carries second request information, and the second request information is used to request the target state of the second terminal device, the second terminal device The target state of the device is the disconnected state or the idle state in the disconnected state or the deactivated state in the disconnected state. Of course, the UE assistance information sent by the second terminal device may also be other messages, as long as it carries the second request information, which is not limited.

Wherein, the second request information includes a state identifier used to indicate the target state that the second terminal device wants to enter, and the state identifier included in the second request information may be the target state that the second terminal device wants to enter, or it may be able to represent the target state that the second terminal device wants to enter.
