FIG. 1 shows a block diagram of a relay network communication system to which the embodiments of the present application can be applied. The relay network communication system includes a remote terminal 11, a relay terminal 12, and a network-side device 13, where the remote terminal 11 and the relay terminal 12 may also be referred to as terminal equipment or user equipment (User Equipment, UE). In the relay network communication system, the terminal that provides the relay service is called the relay terminal (relay UE), and the terminal that is provided with the relay service is called the remote terminal (remote UE). The relay terminal 12 and the remote terminal 11 The link between them is the PC5 link, running the side link interface protocol, and the link between the relay terminal 12 and the network side device 13 is the Uu link, running the Uu link protocol.

In order to better understand the technical solutions provided by the application, the following will explain the technical terms involved in the technical solutions provided by the embodiments of the application:

Inactive state:

The terminal in the inactive state maintains the connection management connected (Connection Management Connected, CM-Connected) state, but its radio resource control (Radio Resource Control, RRC) link is in the inactive state, and its last serving base station (network side device) The context information of the terminal and the link between the terminal and the core network are preserved. The terminal can move in the area configured by the radio access network (New Generation Radio Access Network, NG-RAN) without notifying the NG-RAN. If a terminal is in an inactive state and its last serving base station receives downlink data sent to the terminal, the base station initiates paging to the terminal in the cell corresponding to the RAN-based Notification Area (RNA). If a terminal is in the inactive state, it needs to send uplink data or is paging from the base station, it can tell the base station its inactive wireless network temporary identification during the random result process, and the base station identifies the terminal through the inactive wireless network temporary identification , activate the context of the terminal, and perform data transmission.

The inactive state configuration method, apparatus, and communication device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Please refer to FIG. 2. FIG. 2 is a flowchart of an inactive state configuration method provided by an embodiment of the present application. The inactive state configuration method provided by the embodiment of the present application is applied to a relay terminal. As shown in Figure 2, the inactive state configuration method includes the following steps:

Step 201: In the case that the relay terminal provides a relay service for the remote terminal, the relay terminal configures the relay link to be in an inactive state.

The relay link is a relay link used to provide relay services for the remote terminal, and the relay link includes a side chain between the relay terminal and the remote terminal A sidelink and a Uu link between the relay terminal and the network side device. It should be noted that a relay terminal may establish side links with multiple remote terminals.

The relay link inactive state means that after the relay link is released, the remote terminal, relay terminal, and network-side equipment all retain the wireless connection context related to the relay link. The remote terminal, the relay terminal, and the network-side equipment reactivate the wireless connection context related to the relay link to provide relay services for the remote terminal.

In the embodiment of the present application, the relay terminal provides relay service for the remote terminal, which may mean that the relay terminal provides long-term relay service for the remote terminal, wherein the long-term relay service refers to the service duration longer than the preset duration. Relay service. For example, a user's mobile phone can provide long-term relay services for wearable or portable electronic products such as smart watches, smart glasses, etc.; or, in a home network, the relay terminal can be several remote terminals fixed in the home network Provide long-term relay services, such as providing long-term relay services for smart refrigerators, smart TVs, and sweeping robots.

Understandably, if the relay terminal can provide long-term relay services for the remote terminal, the relay terminal configures the relay link to the inactive state, that is, the side link between the relay terminal and the remote terminal is configured. The configuration is in the inactive state and/or the Uu link between the relay terminal and the network side device is configured in the inactive state. In this way, when the relay link re-enters the active state from the inactive state, the stored wireless connection context can be reactivated and the previous NG connection can be reused to realize data transmission, thus avoiding the need for the relay link to perform data transmission every time. The signaling overhead generated by re-establishing a wireless connection and configuring a relay link reduces the data delay and improves the transmission performance of the communication system.

Optionally, the relay terminal configures the relay link to be in an inactive state, including at least one of the following:

The relay terminal configures the side link to be inactive;

The relay terminal configures the Uu link to be inactive.

Understandably, the relay link includes the side link between the relay terminal and the remote terminal and the Uu link between the relay terminal and the network side device, and the relay terminal configures the relay link to be in an inactive state. , which may be inactive configuration for the side link and/or the Uu link respectively.

Wherein, the relay terminal configures the side link to be inactive, including any of the following:

The relay terminal receives a first request for configuration of a sidelink inactive state sent by a remote terminal, and the relay terminal configures the remote terminal to be in an inactive state based on the first request;

When the sidelink is released, the relay terminal carries first information in the sidelink release information sent to the remote terminal, where the first information is used to configure the remote terminal to be in an inactive state;

The relay terminal receives the first permission information configured in the inactive state of the side link sent by the network side device, and the relay terminal configures the remote terminal to be in the inactive state based on the first permission information;

The relay terminal sends a second request for the configuration of the sidelink inactive state to the network side device, and when the relay terminal receives the second permission information sent by the network side device in response to the second request, Configure the remote terminal to be in an inactive state.

That is to say, the relay terminal configures the side link to be in an inactive state, including the above four embodiments, and the above four embodiments will be described in detail below.

In the first implementation manner, the remote terminal may use PC5RRC signaling to send a first request for sidelink inactive configuration to the relay terminal, and the relay terminal sends the first request based on the received first request to the relay terminal. The remote terminal is configured in an inactive state. Referring to FIG. 2a, step 1. The remote terminal requests the relay terminal to configure the inactive state in the side link, and step 2. The relay terminal releases the side link and configures the inactive state of the side link.

Wherein, the first request includes the identification information of the remote terminal. Optionally, the first request may explicitly or implicitly contain the identification information of the remote terminal, so that the relay terminal can determine which remote terminal needs to be configured in an inactive state based on the identification information. , to ensure the accuracy of the relay terminal configuration in the inactive state.

Optionally, the identification information is carried by at least one of the following:

Sidelink Control Information (SCI);

Medium Access Control Protocol Data Unit (MAC PDU);

PC5 RRC signaling.

For example, the identity information may be the identity document (ID) information of the remote terminal carried by the SCI and the MAC PDU, or the ID information carried in the PC5 RRC signaling. Furthermore, based on the identity information, the relay terminal can also configure the remote terminal that sends the first request to an inactive state in a targeted manner.

Optionally, after the relay terminal configures the remote terminal to be in an inactive state based on the first request, the method further includes:

The relay terminal sends indication information to the remote terminal, where the indication information is used to instruct the remote terminal to implement any one of the following when entering the active state from the inactive state:

continue to use said identifying information;

not use said identifying information;

Configure a new identity information.

That is, after the relay terminal configures the remote terminal to be in an inactive state based on the first request sent by the remote terminal, the relay terminal sends indication information to the remote terminal, where the indication information is used to instruct the remote terminal When the terminal enters the active state from the inactive state, whether the identity information in the original side link can be used, for example, instructing the remote terminal to continue to use the identity information, or instructing the remote terminal not to use the identity information. Identity information, or the indication information may also be identity information instructing the remote terminal to configure a new sidelink inactive state.

In the second implementation manner, the relay terminal may carry first information in the sidelink release information sent to the remote terminal in the case of sidelink release, where the first information is used to configure The remote terminal is in an inactive state. That is to say, the relay terminal can directly configure the remote terminal to enter the inactive state without receiving a request from the remote terminal.

In a third implementation manner, the relay terminal receives the first permission information of the sidelink inactive state configuration sent by the network side device, and the relay terminal releases the sidelink based on the first permission information, and configures the remote terminal is inactive. As shown in Figure 2b, step 1. The network side device allows the relay terminal to configure the inactive state on the side link, step 2. The remote terminal requests the relay terminal to configure the inactive state on the side link, and step 3. Relay The terminal releases the side link and configures the side link inactive state. That is to say, the relay terminal needs to first obtain the permission of the network side device to configure the inactive state of the side link, and then configure the remote terminal to be in the inactive state.

Wherein, the first permission information is configured by any one of the following:

Dedicated RRC signaling;

system information;

Non Access Stratum (NAS) messages.

For example, the first permission information may be configured through dedicated RRC signaling, or configured through system information, or configured through NAS messages.

Optionally, the relay terminal configures the remote terminal to be in an inactive state based on the first permission information, including:

When the relay terminal receives a third request for configuring the sidelink inactive state sent by the remote terminal, the relay terminal, in response to the third request, configures the configuration based on the first permission information. The remote terminal is in an inactive state.

That is to say, the relay terminal first receives the first permission information of the sidelink inactive state configuration sent by the network side device, and then if the relay terminal receives the sidelink inactive state configuration request sent by the remote terminal, Then, when configuring the side link with the remote terminal, the relay terminal may configure the remote terminal to be in an inactive state based on the first permission information.

Optionally, the third request sent by the remote terminal may include identification information of the remote terminal, and the identification information may be carried by at least one of SCI, MAC PDU, and PC5 RRC signaling; the relay terminal After the remote terminal is configured to be in the inactive state, indication information may also be sent to the remote terminal to indicate whether the remote terminal will continue to use the identity information or configure a new identity when the remote terminal enters the active state from the inactive state. identifying information.

In a fourth implementation manner, the relay terminal first sends a second request for sidelink inactive configuration to the network side device, and the network side device can respond to the second request and send the second request to the relay terminal. permission information to allow the remote terminal to be configured in an inactive state, and the relay terminal configures the remote terminal to be in an inactive state based on the second permission information. Different from the third embodiment, in this embodiment, the relay terminal actively sends a sidelink inactive state configuration request to the network side device, and then the network side device sends permission information to the relay terminal based on the request.

Alternatively, before the relay terminal sends the second request for configuration in the inactive state to the network side device, the method further includes:

The relay terminal receives a fourth request for sidelink inactive state configuration sent by the remote terminal.

That is to say, the relay terminal may request the network side device whether to allow the configuration of the remote terminal to enter the sidelink inactive state based on the sidelink inactive state configuration request sent by the remote terminal. The permission information (second permission information) sent by the network side device, the relay terminal configures the remote terminal to be in an inactive state when releasing the side link with the remote terminal. As shown in Figure 2c, step 1. The remote terminal requests the relay terminal to configure the inactive state in the side link; step 2. The relay terminal requests the network side device to configure the inactive state for the remote terminal; step 3. The network side device agrees to configure the inactive state of the side link for the remote terminal; step 4. The relay terminal releases the side link and configures the inactive state of the side link for the remote terminal.

Wherein, the sidelink inactive state configuration request sent by the remote terminal may include the identification information of the remote terminal, and the identification information may be carried by at least one of SCI, MAC PDU, and PC5 RRC signaling, For a specific implementation manner of the identity identification information, reference may be made to the description in Embodiment 1 above, which will not be repeated here.

In this embodiment of the present application, the relay terminal may also configure the Uu link to be in an inactive state. Optionally, the relay terminal configures the Uu link to be in an inactive state, including any of the following:

The relay terminal determines the Uu link context related to the relay service, and configures the Uu link to an inactive state based on the Uu link context;

The relay terminal receives the configuration that the Uu link enters the inactive state from the network side device, determines the Uu link context related to the relay service, and configures the Uu link as inactive based on the Uu link context state;

The relay terminal sends a fifth request for configuration of the Uu link in the inactive state to the network side device, and configures the Uu link in the inactive state based on a response message of the network side device in response to the fifth request.

Optionally, the relay terminal may actively configure the Uu link to be in an inactive state. The relay terminal determines the Uu link context related to the relay service, and configures the Uu link in an inactive state based on the Uu link context.

For example, the relay terminal may re-use the existing inactive state request and configuration process. When the network side device reserves the wireless link context for the relay terminal entering the inactive state, in addition to retaining the wireless connection related to the relay terminal itself It also retains the context of the Uu link of the relay service, such as the backhaul bearer and bearer mapping, backhaul related quality of service (Quality of Service, QoS) parameters, preconfigured resources and other configuration information. In this way, the relay terminal can also configure the Uu link in the inactive state by determining the Uu link related to the relay service.

Alternatively, the Uu link may also be configured to be in an inactive state through a network side device. For example, the network side device sends the configuration information that the Uu link enters the inactive state to the relay terminal, and the relay terminal determines the Uu link related to the relay service through the configuration information that the Uu link enters the inactive state received from the network side device. and then configure the Uu link to an inactive state based on the Uu link context.

Alternatively, the relay terminal may also request the network side device to configure the inactive state of the Uu link. For example, the relay terminal sends a fifth request for Uu link inactive state configuration to the network side device, and the network side device sends a response message to the relay terminal based on the fifth request, where the response message may instruct the relay terminal to perform Inactive state configuration of the Uu link, and then the relay terminal configures the Uu link in the inactive state based on the response message.

Wherein, when the relay terminal sends the fifth request for the configuration of the Uu link inactive state to the network side device, the method further includes:

The relay terminal sends a sixth request to the network-side device, where the sixth request is used to explicitly or implicitly request the network-side device to retain the context related to the wireless connection of the relay terminal and to retain the relay service The relevant Uu link context.

Understandably, when the relay terminal requests the network-side device for the Uu link to enter the inactive state, it can also explicitly or implicitly request the network-side device not only to retain the context related to the relay terminal's own wireless connection, but also to retain the context related to the wireless connection of the relay terminal itself. The context of the Uu link related to the relay service, such as the backhaul bearer and bearer mapping, backhaul related QoS parameters, preconfigured resources and other configuration information. In this way, the relay terminal can also configure the Uu link to an inactive state based on the context of the Uu link related to the relay service reserved by the network side device.

Optionally, when the sixth request is an explicit request, the sixth request includes indication information, and the indication information is used to request to enter the Uu link inactive state;

When the sixth request is an implicit request, the sixth request includes the capacity of the relay terminal and/or the frequency of the relay terminal serving the remote terminal.

For example, in an explicit request scheme, the relay terminal may add an indication field to the indication information to instruct the relay terminal to request to enter the inactive state of the Uu link, so that the network-side device is based on the explicit request. request, and respond to the relay terminal to decide whether to configure the Uu link as an inactive state. Alternatively, in an implicit request scheme, the relay terminal may report the capacity of the relay terminal and/or the frequency or interval at which the relay terminal serves the remote terminal to the network side equipment, so that the network side equipment can The capacity of the relay terminal and/or the frequency with which the relay terminal serves the remote terminal determines whether to configure the Uu link as inactive.

In the embodiment of the present application, when the relay terminal provides relay services for the remote terminal, the relay terminal can configure the side link and/or the Uu link to an inactive state based on the above-mentioned different methods, so that the intermediate The configuration of the inactive state of the side link and/or the Uu link of the relay terminal is more flexible.

Optionally, after the relay terminal configures the relay link to be in an inactive state, the method further includes:

The relay terminal receives a seventh request for configuration of the relay link in the active state sent by the remote terminal, and configures the remote terminal in the active state.

Understandably, after the remote terminal is configured to be in the inactive state, it can still be configured from the inactive state to the active state based on data transmission requirements. It should be noted that, when the remote terminal is switched from the inactive state to the active state, the side link connection is activated first, and then the Uu link connection is activated.

For the relay terminal, the relay terminal first receives the request for the configuration of the relay link in the active state sent by the remote terminal, and then configures the remote terminal in the active state in response to the request. Wherein, the seventh request for the active state configuration of the relay link sent by the remote terminal may include the identifier of the remote terminal, and then the relay terminal can activate the connection with the remote terminal based on the identifier of the remote terminal. The sidelink context related to the remote terminal, activate the sidelink, and configure the remote terminal to the active state.

It should be noted that when the relay service is applied to the layer 2 relay structure, the remote terminal also needs to send a request for activating the RRC connection to the network side device, and the request may carry the identifier of the remote terminal. , after receiving the request to activate the RRC connection, the network side device activates the RRC configuration related to the remote terminal, thereby activating the Uu link or the backhaul link of the remote terminal, and sends the RRC connection to the remote terminal Activation confirmation message. If the relay service is applied to the layer 3 relay structure, the remote terminal does not need to send a request for activating the RRC connection to the network side device, and the network side device does not need to perform the relevant procedures of RRC connection activation.

As shown in Figure 2d, step 1. The remote terminal sends a sidelink configuration activation request to the relay terminal, and the request carries the sidelink inactive UE identifier; step 2. The relay terminal responds to the request to The remote terminal is configured in an active state, and sends a sidelink configuration activation confirmation message to the remote terminal; in the case where the relay service is applied to the layer 2 relay structure, step 3 is also included. The remote terminal sends the network The side device sends an RRC connection activation message (or a request to activate an RRC connection), which carries the SL-I-RNTI of the remote terminal; step 4. The network side device further activates the RRC configuration related to the remote terminal, and Send an RRC connection activation confirmation message to the remote terminal. If the relay service is applied to the layer 3 structure, the above steps 3 and 4 are not present.

Optionally, the relay terminal receives a seventh request for relay link active state configuration sent by the remote terminal, and configures the remote terminal into the active state, including:

The relay terminal receives the seventh request for the configuration of the active state of the side link sent by the remote terminal, and the relay terminal sends the eighth request for the configuration of the active state of the Uu link to the network side device in response to the seventh request;

The relay terminal receives a response message sent by the network side device in response to the eighth request, and configures the remote terminal into an active state based on the response message.

That is to say, after the relay terminal receives the seventh request for the configuration of the active state of the side link sent by the remote terminal, the relay terminal then sends the eighth request for the configuration of the active state of the Uu link to the network side device. After receiving the eighth request, activate the Uu link of the relay terminal and send back the related configuration, and send a Uu link activation confirmation message to the relay terminal. The end terminal sends a sidelink activation confirmation message to configure the remote terminal into an active state.

It can be understood that, different from the above embodiment, in the above embodiment, the relay terminal can autonomously configure the remote terminal to be in the active state based on the request of the remote terminal; while in this embodiment, it is based on the network side equipment. Configuration to realize the configuration of the active state of the remote terminal.

It should be noted that when the relay service is applied to the layer 2 relay structure, the remote terminal also needs to send a request for activating the RRC connection to the network side device, and the request may carry the identifier of the remote terminal. , after receiving the request to activate the RRC connection, the network side device activates the RRC configuration related to the remote terminal, thereby activating the Uu link of the remote terminal, and sends an RRC connection activation confirmation message to the remote terminal. Alternatively, for the layer 2 relay structure, the remote terminal does not need to send a request to activate the RRC connection to the network-side device, and the network-side device can directly pass the Inactive Radio Network Temporary Identifier (Inactive Radio Network Temporary Identifier) of the remote terminal. , I-RNTI), to determine the relay terminal that provides the relay service for the remote terminal, thereby activating the Uu link. If the relay service is applied to the layer 3 relay structure, the remote terminal does not need to send a request for activating the RRC connection to the network side device, and the network side device does not need to perform the relevant procedures of RRC connection activation.

As shown in Figure 2e, step 1. The remote terminal sends a sidelink configuration activation request to the relay terminal, and the request carries the sidelink inactive UE identifier; step 2. The relay terminal then sends an RRC to the network side device A connection activation message (or a request to activate an RRC connection), which carries the SL-I-RNTI of the remote terminal; Step 3. The network side device activates the RRC configuration related to the remote terminal, thereby activating the remote terminal Uu link, and send the RRC connection activation confirmation message to the relay terminal; Step 4. The relay terminal then sends the sidelink configuration activation confirmation message to the remote terminal; in the relay service applied to the layer 2 relay structure In the case of , it also includes step 5. The remote terminal sends an RRC connection activation message (or a request to activate the RRC connection) to the network side device, and the message carries the SL-I-RNTI of the remote terminal; step 6. The network The side device further activates the RRC configuration related to the remote terminal, and sends an RRC connection activation confirmation message to the remote terminal. If the relay service is applied to the layer 3 structure, the above steps 5 and 6 are also absent.

In addition, when the relay service is applied to a layer 3 relay structure, when the relay terminal sends the eighth request to the network side device, the method further includes:

The relay terminal determines a temporary identifier based on the context of the remote terminal, where the temporary identifier is used to determine the context of the Uu link to be activated.

The temporary identifier may be a sidelink inactive wireless network temporary identifier (Sidelink I-RNTI, SL-I-RNTI). When the relay terminal initiates a request to configure from the inactive state to the active state, the The context of the remote terminal determines the SL-I-RNTI, and then determines the context of the Uu link to be activated according to the SL-I-RNTI, and then activates the context of the Uu link for data transmission.

In this embodiment of the present application, when the relay terminal provides relay services for the remote terminal, the relay terminal configures the relay link to be in the inactive state, and then when the relay link re-enters the active state from the inactive state , the stored wireless connection context can be reactivated and the previous NG connection can be reused to realize data transmission, which avoids the information generated by re-establishing the wireless connection and configuring the relay link every time the relay link performs data transmission. It reduces the overhead, reduces the data delay, and improves the transmission performance of the communication system.

The device may be a mobile terminal or a non-mobile terminal. Exemplarily, the mobile terminal may include, but is not limited to, the types of relay terminals 12 listed above, and the non-mobile terminal may be a server, a network attached storage (NAS), a personal computer (PC), a television A TV (television, TV), a teller machine, or a self-service machine, etc., are not specifically limited in this embodiment of the present application.

The operating system may be an Android (Android) operating system, an ios operating system, or other possible operating systems, which are not specifically limited in the embodiments of the present application.

The inactive state configuration apparatus 300 provided in this embodiment of the present application can implement each process implemented by the method embodiment in FIG. 2 and achieve the same technical effect. To avoid repetition, details are not described here.

Please refer to FIG. 4 . FIG. 4 is a flowchart of another inactive state configuration method provided by an embodiment of the present application. The inactive state configuration method provided by the embodiment of the present application is applied to a remote terminal. As shown in Figure 4, the inactive state configuration method includes the following steps:

Step 401, the remote terminal enters the relay link inactive state based on the configuration of the relay terminal and/or the network side device.

In this embodiment of the present application, when the relay terminal can provide long-term relay services for the remote terminal, the remote terminal enters the relay link non-relay service based on the configuration of the relay terminal and/or the network side device. active state. The long-term relay service refers to a relay service whose service duration is longer than a preset duration, and the relevant definition may refer to the description in the above-mentioned embodiment in FIG. 2 , which will not be repeated here.

Understandably, if the relay terminal can provide long-term relay services for the remote terminal, the relay terminal may configure the remote terminal to be inactive, or the network side device may configure the remote terminal to be inactive. state. In this way, when the remote terminal re-enters the active state from the inactive state, the relay link can realize data transmission by reactivating the stored wireless connection context and reusing the previous NG connection, thus avoiding the need for the relay link every time. The signaling overhead generated by re-establishing the wireless connection and configuring the relay link for each data transmission reduces the data delay and improves the transmission performance of the communication system.

Optionally, the step 401 includes any one of the following:

sending, by the remote terminal, a first request for configuration of a sidelink inactive state to the relay terminal, and entering a sidelink inactive state based on the configuration performed by the relay terminal in response to the first request;

The remote terminal receives the sidelink release information sent by the relay terminal, and the sidelink release information carries first information, and the first information is used to instruct the remote terminal to enter the sidelink non-operation mode. active state;

The remote terminal receives the configuration information from the network-side device forwarded by the relay terminal, and enters a relay link inactive state according to the configuration information.

Understandably, the relay link includes the side link between the relay terminal and the remote terminal and the Uu link between the relay terminal and the network side device, and the inactive state of the relay link is also the side link. At least one item between the inactive state of the link and the inactive state of the Uu link. In the embodiment of the present application, the entry of the remote terminal into the inactive state of the relay link may refer to the entry of the remote terminal into the inactive state of the side link, which specifically includes the following implementation manners.

In the first implementation manner, the remote terminal may send a first request for sidelink inactive state configuration to the relay terminal connected to it through PC5 RRC signaling, so as to request to enter the sidelink inactive state, and the relay The terminal configures the remote terminal to be in an inactive state based on the received first request, and then the remote terminal enters a side-link inactive state.

Optionally, the identification information is carried by any of the following:

SCI, MAC PDU, PC5 RRC signaling.

For example, the identity information may be the identity document (ID) information of the remote terminal carried by the SCI and the MAC PDU, or the ID information carried in the PC5 RRC signaling. Furthermore, based on the identification information, the relay terminal can also configure the remote terminal that sends the first request to the inactive state in a targeted manner, so as to ensure the accuracy of the configuration of the inactive state.

It should be noted that, after the remote terminal enters the relay link inactive state based on the configuration of the relay terminal and/or the network side device, the method further includes:

The remote terminal receives the indication information sent by the relay terminal, where the indication information is used to instruct the remote terminal to implement any one of the following when entering the active state from the inactive state:

continue to use said identifying information;

not use said identifying information;

Configure a new identity information.

That is, after the remote terminal enters the inactive state of the relay link, the relay terminal can send indication information to the remote terminal to indicate whether the remote terminal can enter the active state from the inactive state. Use the identity information in the original side link, for example, instruct the remote terminal to continue to use the identity information, or instruct the remote terminal not to use the identity information, or the indication information may also be Instruct the remote terminal to configure a new side link inactive state identification information.

In the second implementation manner, the remote terminal receives sidelink release information sent by the relay terminal, and the sidelink release information carries information used to instruct the remote terminal to enter the sidelink inactive state, thereby enabling the remote terminal to enter the inactive state of the sidelink. The end terminal can enter the sidelink inactive state. That is to say, the remote terminal can be directly configured by the relay terminal to enter the sidelink inactive state, which is different from the above-mentioned first implementation mode in which the remote terminal needs to send a sidelink inactive state configuration request to the relay terminal first. Only then can the configuration of the inactive side link be implemented.

In a third implementation manner, the remote terminal can receive configuration information from the network side device forwarded by the relay terminal, and enter the sidelink inactive state based on the configuration information. In this implementation manner, the remote terminal enters the side link inactive state based on the configuration of the network side device.

In this embodiment of the present application, the remote terminal can actively request the relay terminal to enter the sidelink inactive state, or can enter the sidelink inactive state based on the active configuration of the relay terminal or the network side device without sending a configuration request. The side-link inactive state makes the way for the remote terminal to enter the side-link inactive state more flexible, and can better meet the needs of different communication scenarios.

Optionally, the step 401 may further include any one of the following:

In the case that the relay service is applied to the layer 2 relay structure, the remote terminal enters the relay link inactive state based on the configuration of the network side device;

In the case where the relay service is applied to the layer 2 relay structure, the remote terminal sends a third request to enter the inactive state of the relay link to the network side device, and based on the response information of the network side device, enters the The relay link is inactive;

In the case where the relay service is applied to a layer 3 relay structure, the remote terminal sends a second request for configuration of a relay link inactive state to the relay terminal, and the remote terminal is based on the The relay terminal enters the relay link inactive state in response to the configuration performed by the second request.

Understandably, for the layer 2 relay structure, the remote terminal has a PC5 RRC connection with the relay terminal to control the side link connection, and there is also an RRC connection with the network side equipment, using It is used for connection and service provision between control and network side equipment. For the layer 3 relay structure, the remote terminal has a PC5 RRC connection with the relay terminal, but there is no RRC connection with the network side equipment. Furthermore, for the layer 2 relay structure and the layer 3 relay structure, there are differences in the manner in which the remote terminal enters the inactive state of the relay link.

When the relay service is applied to the layer 2 relay structure, since there is an RRC connection between the remote terminal and the network side device, the remote terminal can enter the relay link inactive state directly based on the configuration of the network side device . For example, after receiving the configuration information sent from the network-side device to enter the inactive state, the remote terminal enters the side-link inactive state based on the configuration information, so that the remote terminal is directly configured through the network-side device to enter the inactive state. In the active state, there is no need to go through the relay terminal, which further saves the consumption of signaling.

Alternatively, when the relay service is applied to the layer 2 relay structure, the remote terminal may also directly send a request to the network side device to enter the inactive state of the relay link, and the network side device may send a request to the network side device based on the request. The remote terminal sends response information for configuring the remote terminal to enter the sidelink inactive state, and then the remote terminal enters the sidelink inactive state based on the response information. For example, after the network-side device receives a request from the remote terminal to enter the inactive state of the relay link after releasing the relay link, the network-side device can directly configure the terminal to release the relay link and enter the inactive state. Configure the remote terminal to enter the relay link inactive state, and configure the relay terminal to retain the sidelink context related to the remote terminal.

Optionally, the network side device may configure a remote terminal identification code in the inactive state of the Uu link or the side link, which is used to identify the remote terminal in the inactive state of the Uu link or the side link.

In the case where the relay service is applied to the layer 3 relay structure, since there is no RRC connection between the remote terminal and the network side device, the remote terminal first sends the relay link inactive state configuration information to the relay terminal. In the second request, the relay terminal configures the sidelink inactive state configuration of the remote terminal, so that the remote terminal can enter the sidelink inactive state based on the configuration of the relay terminal.

It should be noted that the relay link includes the side link between the remote terminal and the relay terminal and the Uu link between the relay terminal and the network side device, wherein the configuration related to the Uu link is the side link. The mapping relationship between the bearer and the Uu link bearer, and the radio resource configuration related to the Uu link, etc. For the layer 2 relay structure, the inactive state configuration of the relay link can be directly configured by the network side device; for the layer 3 relay structure, the relay terminal can provide auxiliary information to the network side device, including the information related to the remote terminal. Relay link bearer and required resources, such as uplink and downlink rates.

Wherein, when the relay service is applied to a layer 2 relay structure, the method further includes:

The remote terminal receives the temporary identification code related to the inactive state sent by the network side device.

For example, for the layer 2 relay structure, the network side device can allocate a relay link SL-I-RNTI to the remote terminal entering the inactive state, and send it to the remote terminal, so that the remote terminal entering the inactive state can Terminal is identified.

For the layer 3 relay structure, when the network side device configures the relay link to enter the inactive state, it can allocate one or more SL-I-RNTIs to the relay terminal, corresponding to one or more context configurations, or a SL-I-RNTI corresponds to one context configuration, and different context configurations correspond to different Uu link bearers and radio resource configurations.

In the embodiment of the present application, for different relay structures, it is possible to configure the remote terminal to enter the relay link inactive state based on different configuration methods according to different relay structures, so as to ensure that the remote terminal relay link is in the inactive state. The configuration is realized to save signaling and reduce data transmission delay.

Optionally, after the step 401, the method may further include:

The remote terminal sends a fourth request for sidelink active state configuration to the relay terminal, and enters the sidelink active state based on the configuration of the relay terminal.

Understandably, after entering the inactive state of the relay link, the remote terminal can still be configured from the inactive state to the active state based on data transmission requirements. It should be noted that when the remote terminal is switched from the inactive state to the active state, the side link connection is activated first, and then the Uu link connection is activated.

The remote terminal needs to activate the sidelink connection first, and the remote terminal first sends a fourth request for the configuration of the sidelink active state to the relay terminal. After receiving the fourth request, the relay terminal responds to the fourth request. , configure the remote terminal to enter the active side link state. In this way, the service requirements of the remote terminal can also be met, and the normal transmission of data between the remote terminal and the relay terminal can be realized.

Wherein, the fourth request for the active state configuration of the relay link sent by the remote terminal may include the identifier of the remote terminal, and then the relay terminal can activate the connection with the remote terminal based on the identifier of the remote terminal. The sidelink context related to the remote terminal, activate the sidelink, and configure the remote terminal to the active state.

It should be noted that, in the case where the relay service is applied to the layer 2 relay structure, after the remote terminal enters the sidelink active state, the method further includes:

The remote terminal sends a fifth request for activating an RRC connection to the network side device, and receives an RRC connection activation confirmation message sent by the network side device.

Understandably, for the layer 2 relay structure, the remote terminal has an RRC connection with the network side device. After the remote terminal enters the sidelink active state, the remote terminal can directly send an RRC connection activation message to the network side device. The fifth request, the fifth request may carry the identifier of the remote terminal. After receiving the fifth request for activating the RRC connection, the network side device activates the RRC configuration related to the remote terminal, thereby activating the remote terminal and send an RRC connection activation confirmation message to the remote terminal.

If the relay service is applied to the layer 3 relay structure, since there is no RRC connection between the remote terminal and the network side device, the remote terminal does not need to send a request to activate the RRC connection to the network side device, and the network side device also does not need to send a request to activate the RRC connection. There is no need to perform the relevant procedures of RRC connection activation.

It should be noted that after the relay terminal receives the fourth request for the active configuration of the side link sent by the remote terminal, the relay terminal can further send the request for the active configuration of the Uu link to the network side device, and then the network The side device activates the Uu link of the relay terminal and the related configuration of backhaul, and sends a Uu link activation confirmation message to the relay terminal. After receiving the confirmation message of Uu link activation, the relay terminal sends a side link to the remote terminal. A channel activation confirmation message is sent to configure the remote terminal to an active state.

In the embodiment of the present application, in the case where the relay terminal provides relay services for the remote terminal, the remote terminal can enter the relay link inactive state based on the configuration of the relay terminal and/or the network side device, and then when When the remote terminal re-enters the active state from the inactive state, the relay link can realize data transmission by reactivating the stored wireless connection context and reusing the previous NG connection, thus avoiding the need for the relay link to perform data transmission every time. The signaling overhead generated by re-establishing the wireless connection and configuring the relay link for transmission reduces the data delay and improves the transmission performance of the communication system.

It should be noted that, in the inactive state configuration method provided by the embodiments of the present application, the execution subject may be an inactive state configuration device, or a control module in the inactive state configuration device for executing the inactive state configuration method.

Please refer to FIG. 6 . FIG. 6 is a flowchart of another inactive state configuration method provided by an embodiment of the present application. The inactive state configuration method provided by the embodiment of the present application is applied to a network side device. As shown in Figure 6, the inactive state configuration method includes the following steps:

Step 601: In the case that the relay terminal can provide the relay service for the remote terminal, the network side device configures the relay terminal and/or the remote terminal to be in an inactive state.

Understandably, the network side device can configure the relay terminal and/or the remote terminal to be in an inactive state. For example, the network side device may configure the relay terminal to be in an inactive state, and the relay terminal may configure the remote terminal connected to it to be inactive state; or, for the layer 2 relay structure, since the remote terminal and the network side There is an RRC connection between the devices, and the network-side device can also directly configure the remote terminal to be inactive without going through the relay terminal.

In the embodiment of the present application, in the case where the relay terminal provides relay services for the remote terminal, the network side device can configure the relay terminal and/or the remote terminal to be in an inactive state, and then when the relay terminal and/or the remote terminal are in an inactive state When the end terminal re-enters the active state from the inactive state, the relay link can realize data transmission by reactivating the stored wireless connection context and reusing the previous NG connection, which avoids the data transmission of the relay link every time. The signaling overhead generated by re-establishing the wireless connection and configuring the relay link will reduce the data delay and improve the transmission performance of the communication system.

Optionally, the network side device configures the relay terminal and/or the remote terminal to be in an inactive state, including any of the following:

The network side device receives the first request for configuration of the inactive state of the Uu link sent by the relay terminal, and configures the relay terminal to be in the inactive state.

In a first implementation manner, the network-side device may actively send to the relay terminal first permission information for configuring the sidelink inactive state, where the first permission information is used to allow the relay terminal to configure the remote terminal is inactive. Understandably, after receiving the first permission information, the relay terminal releases the side link and configures the remote terminal to be in an inactive state.

Optionally, before the network side device sends the first permission information configured in the inactive state of the side link to the relay terminal, the method further includes:

The network side device receives the first request for configuration of the side link inactive state sent by the relay terminal.

That is to say, the relay terminal first sends a first request for the configuration of the sidelink inactive state to the network side device, and the network side device sends the first permission for the configuration of the sidelink inactive state to the relay terminal based on the first request. information. Further, the relay terminal may configure the remote terminal to be in the inactive state based on the first permission information in the case of receiving the request for the configuration of the sidelink inactive state sent by the remote terminal. .

Wherein, the first permission information may be configured by any of the following:

Carry at least one item; after configuring the remote terminal to be in the inactive state, the relay terminal may also send indication information to the remote terminal to indicate whether the remote terminal will continue to use the identity identification when it enters the active state from the inactive state information, or configure a new identity information.

In the second implementation manner, the network side device configures the relay terminal to be in the inactive state when receiving the first request for configuring the inactive state of the Uu link sent by the relay terminal. Wherein, when the network side device configures the relay terminal to be in an inactive state, the network side device may retain the Uu link context related to the relay service and the context related to the wireless connection of the relay terminal.
