Description
The present disclosure relates to the field of communications technologies, and in particular, to an activation state determining method, apparatus, and device, and a storage medium.
In a communication system, direct communication between User Equipments (UEs) is achieved by introducing a side-link (Sidelink, SL) communication scheme. And, in order to save the power consumption of the SL UE, discontinuous reception (Discontinuous Reception, DRX) of the SL is introduced, i.e. the receiving UE listens to SCI (sidelink control information, side-uplink control information) of the second phase on the logical channel only in active state. Further, the UE may not directly communicate with the base station, but communication with the base station may be achieved through a relay of another UE. Wherein a UE not connected to the base station is called a remote UE (remote UE), a UE providing a relay function is called a relay UE (relay UE), and the remote UE and the relay UE can communicate through SL unicast.
In the related art, a remote UE in an idle state may send a radio resource control (Radio Resource Control, RRC) establishment request message to a relay UE, so that the relay UE forwards the RRC establishment request message to a base station, forwards an RRC establishment message sent by the base station to the remote UE, and when the remote UE completes a connection establishment procedure, sends an RRC connection establishment completion message to the relay UE, and the relay UE forwards the RRC connection establishment completion message to the base station to notify the base station that the connection establishment procedure is completed; and the remote UE in the inactive state may send an RRC resume request message to the relay UE, so that the relay UE forwards the RRC resume request message to the base station, and forwards the RRC resume message sent by the base station to the remote UE, and when the remote UE completes the connection resume procedure, the remote UE also sends an RRC connection resume complete message to the relay UE, and then the relay UE forwards the RRC connection resume complete message to the base station to notify the base station that the connection resume procedure is completed; and when the remote UE fails in connection, an RRC reestablishment request message may be sent to the relay UE, so that the relay UE forwards the RRC reestablishment request message to the base station, and forwards the RRC reestablishment message sent by the base station to the remote UE.
However, in the related art, after the relay UE sends the RRC setup/resume/reestablish message to the remote UE, the relay UE may enter the SL DRX sleep state, that is, the setup/resume/reestablish procedure is not completed yet, and the relay UE may enter the SL DRX sleep state, so that the RRC connection setup/resume/reestablish complete message forwarded by the remote UE cannot be received, which may cause a delay in the connection setup/connection resume/connection reestablish procedure, thereby affecting the communication stability of SL.

The activation state determination method, apparatus, device and storage medium provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
Fig. 2 is a flowchart of an activation state determining method provided in an embodiment of the present disclosure, where the method is performed by a relay UE, and as shown in fig. 2, the activation state determining method may include the following steps:
Step 201, in response to receiving the first message sent by the remote UE, the relay UE enters an active state to monitor a side uplink (Sidelink, SL) between the remote UE and the relay UE.
Wherein, in one embodiment of the present disclosure, the first message may be a message for requesting a specific flow or a message transmitted through a first transmission manner.
In one embodiment of the present disclosure, the specific flow may be at least one of the following:
an RRC connection establishment procedure;
an RRC connection recovery procedure;
RRC connection reestablishment procedure.
And, in one embodiment of the present disclosure, the first message for requesting a specific flow may include at least one of the following:
An RRC setup request message;
An RRC resume request message;
RRC reestablishment request message.
Further, in an embodiment of the present disclosure, the first transmission manner may include at least one of the following:
transmitting through a first bearer;
Transmitting over a particular logical channel;
Transmitted over a first radio link control (Radio Link Control, RLC).
Wherein the first bearer may comprise a signaling radio bearer (SIGNALLING RADIO BEARER, SRB) 0; the first RLC may include SL-RLC0; the specific logical channel may be any one logical channel or any of several logical channels, and may be predetermined based on a protocol.
Further, it should be noted that, for the relay UE, if the message received from the remote UE is the first message for requesting the specific flow, the relay UE may know the content and the purpose of the first message, and then the relay UE may directly determine that the remote UE requests the specific flow based on the first message; and if the message received by the relay UE from the remote UE is the first message transmitted by the first transmission mode, the relay UE cannot know the content and the purpose of the first message, and the relay UE can determine the content and the purpose of the first message only by the transmission mode of the first message, wherein in one embodiment of the present disclosure, when the transmission mode of the first message is the first transmission mode, it means that the remote UE requests a specific flow.
It can be seen that, in one embodiment of the present disclosure, when the relay UE receives the first message sent by the remote UE and used for requesting the specific flow or receives the first message sent by the remote UE through the first transmission manner, it indicates that the remote UE requests the specific flow, at this time, the remote UE should forward the first message to the network device (such as the base station), and the relay UE should act as a relay to implement subsequent interaction between the remote UE and the network device, so as to complete the specific flow requested by the remote UE. But due to the discontinuous reception (Discontinuous Reception, DRX) mechanism of SL, the relay UE will only monitor SL of the relay UE and the remote UE in the active state.
Therefore, in one embodiment of the present disclosure, when the relay UE receives the first message sent by the remote UE and used for requesting a specific flow or transmitting the first message in the first transmission manner, the relay UE should enter an active state, and in the active state, the relay UE will monitor SL between the remote UE and the relay UE, so that it can be ensured that the relay UE can successfully receive the message sent by the remote UE, and further ensure that the relay UE can successfully perform a relay function between the remote UE and the network device, and ensure that the specific flow requested by the remote UE can be successfully performed.
Step 202, the relay UE stops the activation state in response to the specific condition being satisfied.
Among other things, in one embodiment of the present disclosure, the particular condition may include any of the following:
The specific flow is executed;
The specific flow is refused to be executed;
the relay UE transmits the message in a first transmission mode;
the relay UE transmits the message through the second transmission mode.
Among them, in one embodiment of the present disclosure, the above-mentioned "the relay UE transmits the message through the first transmission manner" means that: the relay UE transmitting a message to the remote UE via the first transmission scheme, and when the relay UE transmits the message via the first transmission scheme, the relay UE: the specific procedure requested by the remote UE is refused to be performed. The related description about the first transmission mode can be described with reference to the above embodiments.
In one embodiment of the present disclosure, the above-mentioned "the relay UE transmits the message through the second transmission manner" means that: the relay UE receives the message transmitted by the remote UE through the second transmission mode. The second transmission mode may include at least one of the following:
Transmitting through a second bearer;
Transmitting over a particular logical channel;
Transmitted over the second RLC.
Wherein the second bearer may include SRB1 and the second RLC may include SL-RLC1; the specific logical channel may be any one logical channel or any of several logical channels, and may be predetermined based on a protocol.
In one embodiment of the present disclosure, when the relay UE transmits a message through the second transmission manner, it is illustrated that: the execution of the specific flow requested by the remote UE is completed.
And, a detailed description of how the relay UE transmits the message through the first transmission manner and how the message is transmitted through the second transmission manner will be described in the following embodiments.
It can be seen from the above that the above "specific conditions" are essentially: when the execution of the specific flow requested by the remote UE is completed, or the execution of the specific flow requested by the remote UE is refused. In this disclosure, the relay UE may stop the active state mainly when the specific flow requested by the remote UE is executed or the specific flow requested by the remote UE is refused to be executed.
Based on this, in one embodiment of the present disclosure, the start time of the active state of the remote UE is: when the remote UE requests a specific flow; the stopping time of the activation state of the remote UE is: when the execution of the specific flow requested by the remote UE is completed or refused to be executed. Therefore, in the whole process of requesting the specific flow by the remote UE, the relay UE is in an activated state, so that the situation that the specific flow requested by the remote UE is not completed yet and the relay UE enters the SL DRX sleep state can be avoided, the on-time execution of the specific flow requested by the remote UE is ensured, the delay of the specific flow is avoided, and the communication stability of SL is ensured.
In summary, in the method for determining an activation state provided in the present disclosure, in response to a relay UE receiving a first message sent by a remote UE, the relay UE enters an activation state to monitor SL between the remote UE and the relay UE; the first message is used for requesting a specific flow or transmitting in a first transmission mode; in response to a specific condition being met, the relay UE ceases to activate state; the specific condition includes any one of the specific flow being executed, the specific flow being refused to be executed, the relay UE transmitting the message through the first transmission scheme, and the relay UE transmitting the message through the second transmission scheme. In the disclosure, when the relay UE receives a first message sent by the remote UE and used for requesting a specific flow or transmitting the first message in a first transmission mode, it is indicated that the remote UE requests the specific flow from the relay UE; when the relay UE transmits a message in a first transmission mode, the specific flow of the remote UE request is refused to be executed; when the relay UE transmits the message through the second transmission mode, it is indicated that the execution of the specific procedure requested by the remote UE is completed. As can be seen from this disclosure, when the remote UE requests a specific procedure, the relay UE enters an active state, and when the execution of the specific procedure requested by the remote UE is completed or is refused to be executed, the relay UE stops the active state. The relay UE is ensured to be in an activated state in the whole process of the specific flow requested by the remote UE, so that the condition that the specific flow requested by the remote UE is not completed yet and the relay UE enters the SL DRX sleep state is avoided, the on-time execution of the specific flow requested by the remote UE is ensured, the delay of the specific flow is avoided, and the communication stability of SL is ensured.

Step 301, in response to receiving a first message sent by the remote UE, the relay UE immediately enters an active state to monitor a side uplink SL between the remote UE and the relay UE; the first message is used to request a specific flow or transmitted via a first transmission means.
In the embodiment of the present disclosure, when the relay UE receives the first message sent by the remote UE, the relay UE immediately enters the active state, which can be understood that the first message triggers the relay UE to enter the active state.
Further details regarding step 301 are described with reference to the above embodiments.
In summary, in the method for determining an activation state provided in the present disclosure, in response to a relay UE receiving a first message sent by a remote UE, the relay UE enters an activation state to monitor SL between the remote UE and the relay UE; the first message is used for requesting a specific flow or transmitting in a first transmission mode; in response to a specific condition being met, the relay UE ceases to activate state; the specific condition includes any one of the specific flow being executed, the specific flow being refused to be executed, the relay UE transmitting the message through the first transmission scheme, and the relay UE transmitting the message through the second transmission scheme. In the disclosure, when the relay UE receives a first message sent by the remote UE and used for requesting a specific flow or transmitting the first message in a first transmission mode, it is indicated that the remote UE requests the specific flow from the relay UE; when the relay UE transmits a message in a first transmission mode, the specific flow of the remote UE request is refused to be executed; when the relay UE transmits the message through the second transmission mode, it is indicated that the execution of the specific procedure requested by the remote UE is completed. As can be seen from this disclosure, when the remote UE requests a specific procedure, the relay UE enters an active state, and when the execution of the specific procedure requested by the remote UE is completed or is refused to be executed, the relay UE stops the active state. The relay UE is ensured to be in an activated state in the whole process of the specific flow requested by the remote UE, so that the condition that the specific flow requested by the remote UE is not completed yet and the relay UE enters the SL DRX sleep state is avoided, the on-time execution of the specific flow requested by the remote UE is ensured, the delay of the specific flow is avoided, and the communication stability of SL is ensured.
Fig. 4 is a flowchart of an activation state determining method provided by an embodiment of the present disclosure, where the method is performed by a relay UE, and as shown in fig. 4, the activation state determining method may include the following steps:
Step 401, a timer is started in response to receiving a first message sent by the remote UE.
Step 402, in response to the timer timeout, the relay UE enters an active state.
From the foregoing, it can be seen that the relay UE enters the active state to monitor SL between the remote UE and the relay UE, so as to ensure that the relay UE can successfully receive the message sent by the remote UE, thereby enabling the relay UE to successfully perform a relay function between the remote UE and the network device, and ensuring that a specific procedure requested by the remote UE can be successfully performed.
However, it should be noted that after the relay UE receives the first message sent by the remote UE, the relay UE will forward the first message to the network device first, receive a response message of the network device to the first message, and then send the response message to the remote UE, and receive a message returned by the remote UE. It can be seen that, after the relay UE receives the first message sent by the remote UE, it is not required to immediately receive the message from the remote UE, but it is required to receive the message from the remote UE after a period of time. Based on this, in one embodiment of the present disclosure, after the relay UE receives the first message sent by the remote UE, the relay UE may not immediately enter the active state, but may first time a period based on a timer, and when the timer expires, the relay UE delays entering the active state again, so that the time in which the relay UE is in the active state may be shortened, and the electric quantity is saved. Also, in one embodiment of the present disclosure, the timing duration of the timer satisfies the following condition: the timing duration is smaller than or equal to the shortest interval between two adjacent interactions between the relay UE and the remote UE, so that when the relay UE is delayed to enter the active state after the timer is overtime, the normal interaction between the relay UE and the remote UE is not influenced, and the communication stability of SL is ensured.
Further, in one embodiment of the present disclosure, the timing duration of the timer may be configured by the network device to the relay UE, such as may be configured by the network device to the relay UE through an RRC message.
In summary, in the method for determining an activation state provided in the present disclosure, in response to a relay UE receiving a first message sent by a remote UE, the relay UE enters an activation state to monitor SL between the remote UE and the relay UE; the first message is used for requesting a specific flow or transmitting in a first transmission mode; in response to a specific condition being met, the relay UE ceases to activate state; the specific condition includes any one of the specific flow being executed, the specific flow being refused to be executed, the relay UE transmitting the message through the first transmission scheme, and the relay UE transmitting the message through the second transmission scheme. In the disclosure, when the relay UE receives a first message sent by the remote UE and used for requesting a specific flow or transmitting the first message in a first transmission mode, it is indicated that the remote UE requests the specific flow from the relay UE; when the relay UE transmits a message in a first transmission mode, the specific flow of the remote UE request is refused to be executed; when the relay UE transmits the message through the second transmission mode, it is indicated that the execution of the specific procedure requested by the remote UE is completed. As can be seen from this disclosure, when the remote UE requests a specific procedure, the relay UE enters an active state, and when the execution of the specific procedure requested by the remote UE is completed or is refused to be executed, the relay UE stops the active state. The relay UE is ensured to be in an activated state in the whole process of the specific flow requested by the remote UE, so that the condition that the specific flow requested by the remote UE is not completed yet and the relay UE enters the SL DRX sleep state is avoided, the on-time execution of the specific flow requested by the remote UE is ensured, the delay of the specific flow is avoided, and the communication stability of SL is ensured.
Fig. 5 is a flowchart of an activation state determining method provided by an embodiment of the present disclosure, where the method is performed by a relay UE, and as shown in fig. 5, the activation state determining method may include the following steps:
Step 501, in response to the relay UE receiving the second message sent by the remote UE, the relay UE stops activating the state.
In one embodiment of the present disclosure, the second message may be a message transmitted through the second transmission manner or a message for indicating that the specific flow is performed.
Specifically, the second message for indicating that the specific flow is performed may include at least one of the following:
RRC setup complete message;
RRC resume complete message;
RRC reestablishment complete message.
Further, in an embodiment of the present disclosure, the second transmission manner may include at least one of the following:
Transmitting through a second bearer;
Transmitting over a particular logical channel;
Transmitted over the second RLC.
Wherein the second bearer may comprise SRB1; the second RLC may include SL-RLC1; the specific logical channel may be any one logical channel or any of several logical channels, and may be predetermined based on a protocol.
Further, it should be noted that, for the relay UE, if the message received from the remote UE is the above-mentioned second message for indicating that the specific flow is performed, the relay UE may know the content and the purpose of the second message, and then the relay UE may directly determine that the specific flow requested by the remote UE is performed based on the second message; and if the message received by the relay UE from the remote UE is the second message transmitted by the second transmission mode, the relay UE cannot know the content and the purpose of the second message, and the relay UE can determine the content and the purpose of the second message only by the transmission mode of the second message, wherein in one embodiment of the present disclosure, when the transmission mode of the second message is the second transmission mode, it means that the specific flow requested by the remote UE is executed.
It can be known that, in one embodiment of the present disclosure, when the relay UE receives the second message sent by the remote UE through the second transmission manner or receives the second message sent by the remote UE and used for indicating that the specific flow is performed, the remote UE requests that the specific flow is performed, and then the remote UE forwards the second message to the network device (such as the base station) to inform the network device that the specific flow requested by the remote UE is performed, and the relay UE does not need to monitor the SL link between the relay UE and the remote UE any more, at this time, the relay UE may stop the active state, so that the power consumption may be saved.
In summary, in the method for determining an activation state provided in the present disclosure, in response to a relay UE receiving a first message sent by a remote UE, the relay UE enters an activation state to monitor SL between the remote UE and the relay UE; the first message is used for requesting a specific flow or transmitting in a first transmission mode; in response to a specific condition being met, the relay UE ceases to activate state; the specific condition includes any one of the specific flow being executed, the specific flow being refused to be executed, the relay UE transmitting the message through the first transmission scheme, and the relay UE transmitting the message through the second transmission scheme. In the disclosure, when the relay UE receives a first message sent by the remote UE and used for requesting a specific flow or transmitting the first message in a first transmission mode, it is indicated that the remote UE requests the specific flow from the relay UE; when the relay UE transmits a message in a first transmission mode, the specific flow of the remote UE request is refused to be executed; when the relay UE transmits the message through the second transmission mode, it is indicated that the execution of the specific procedure requested by the remote UE is completed. As can be seen from this disclosure, when the remote UE requests a specific procedure, the relay UE enters an active state, and when the execution of the specific procedure requested by the remote UE is completed or is refused to be executed, the relay UE stops the active state. The relay UE is ensured to be in an activated state in the whole process of the specific flow requested by the remote UE, so that the condition that the specific flow requested by the remote UE is not completed yet and the relay UE enters the SL DRX sleep state is avoided, the on-time execution of the specific flow requested by the remote UE is ensured, the delay of the specific flow is avoided, and the communication stability of SL is ensured.
Fig. 6 is a flowchart of an activation state determining method provided by an embodiment of the present disclosure, where the method is performed by a relay UE, and as shown in fig. 6, the activation state determining method may include the following steps:
step 601, in response to the relay UE sending a third message to the remote UE, the relay UE stops the activation state.
Wherein, in one embodiment of the present disclosure, the third message may be a message transmitted through the first transmission manner or a message for indicating that the specific flow is refused to be performed.
Specifically, the third message for indicating that the specific procedure is refused to be performed may include an RRC refusal message.
And, the description about the first transmission manner may be described with reference to the above-described embodiments.
Further, it should be noted that, for the relay UE, if the message received from the remote UE is the third message for indicating that the specific flow is refused to be executed, the relay UE may know the content and the purpose of the third message, and then the relay UE may directly determine that the specific flow requested by the remote UE is refused to be executed based on the third message; and if the message received by the relay UE from the remote UE is the third message transmitted by the first transmission mode, the relay UE cannot know the content and the purpose of the third message, and the relay UE can determine the content and the purpose of the third message only by the transmission mode of the third message, wherein in one embodiment of the present disclosure, when the relay UE sends the third message to the remote UE by the first transmission mode, it means that the specific flow requested by the remote UE is refused to be executed.
It can be seen that, in one embodiment of the present disclosure, when the relay UE sends the third message to the remote UE through the first transmission manner or sends the third message to the remote UE, which indicates that the specific flow is refused to be executed, the specific flow requested by the remote UE is terminated, and at this time, the relay UE does not need to monitor the SL link between the relay UE and the remote UE, and the relay UE may stop the active state, so that power consumption may be saved.
In summary, in the method for determining an activation state provided in the present disclosure, in response to a relay UE receiving a first message sent by a remote UE, the relay UE enters an activation state to monitor SL between the remote UE and the relay UE; the first message is used for requesting a specific flow or transmitting in a first transmission mode; in response to a specific condition being met, the relay UE ceases to activate state; the specific condition includes any one of the specific flow being executed, the specific flow being refused to be executed, the relay UE transmitting the message through the first transmission scheme, and the relay UE transmitting the message through the second transmission scheme. In the disclosure, when the relay UE receives a first message sent by the remote UE and used for requesting a specific flow or transmitting the first message in a first transmission mode, it is indicated that the remote UE requests the specific flow from the relay UE; when the relay UE transmits a message in a first transmission mode, the specific flow of the remote UE request is refused to be executed; when the relay UE transmits the message through the second transmission mode, it is indicated that the execution of the specific procedure requested by the remote UE is completed. As can be seen from this disclosure, when the remote UE requests a specific procedure, the relay UE enters an active state, and when the execution of the specific procedure requested by the remote UE is completed or is refused to be executed, the relay UE stops the active state. The relay UE is ensured to be in an activated state in the whole process of the specific flow requested by the remote UE, so that the condition that the specific flow requested by the remote UE is not completed yet and the relay UE enters the SL DRX sleep state is avoided, the on-time execution of the specific flow requested by the remote UE is ensured, the delay of the specific flow is avoided, and the communication stability of SL is ensured.
As can be seen from the foregoing, in the present disclosure, the activation state start time of the relay UE is: when the relay UE receives the first message sent by the remote UE, or after the relay UE receives the first message sent by the remote UE, a timer is started, and when the timer expires. The stop time of the activation state of the relay UE is: when the relay UE receives the second message sent by the remote UE, or when the relay UE sends the third message to the remote UE.
Based on this, the activation time of the relay UE may be, for example: starting from the relay UE receiving the first message sent by the remote UE (e.g., receiving the message sent by the remote UE through SL-RLC 0), stopping until receiving the second message sent by the remote UE (e.g., receiving the message sent by the remote UE through SL-RLC 1). Or the activation time of the relay UE may be: starting from the relay UE receiving the first message sent by the remote UE (e.g., receiving the message sent by the remote UE through SL-RLC 0), until the relay UE stops sending the third message to the remote UE (e.g., sending the message to the remote UE through SL-RLC 0).
Furthermore, it should be noted that, when the start time of the active state of the relay UE in the present disclosure is after the relay UE receives the first message sent by the remote UE, since the relay UE can only receive the message sent by the remote UE when in the active state, when the relay UE receives the first message sent by the remote UE (i.e., before the start time of the active state of the relay UE in the present disclosure), the relay UE is also in the active state, but the active state in which the relay UE receives the first message sent by the remote UE does not conflict with the active state of the relay UE determined in the present disclosure. Specifically, in a communication system, there are a plurality of different flows to control the activation time (i.e., start time and stop time) of the activation state of the UE, and the activation times of the UEs controlled by the different flows may be coincident or not. The start time of the activation state of the flow control in the disclosure is mainly "when the relay UE receives the first message sent by the remote UE, or after the relay UE receives the first message sent by the remote UE, the timer is started, and the stop time is mainly" when the relay UE receives the second message sent by the remote UE, or when the relay UE sends the third message to the remote UE "when the relay UE receives the first message sent by the remote UE, where the activation state of the relay UE is not controlled by the flow of the disclosure but controlled by other flows, and the start time and the stop time of the activation state of the relay UE do not conflict with the activation time of the activation state of the disclosure.
Fig. 7 is a flowchart of an activation state determining method provided in an embodiment of the present disclosure, where the method is performed by a network device, and as shown in fig. 7, the activation state determining method may include the following steps:
Step 701, configuring the timing duration of the timer to the relay UE.
Wherein, in one embodiment of the disclosure, the timer is mainly used for: when the relay UE receives the first message sent by the remote UE, the relay UE does not immediately enter the active state, but delays entering the active state based on the timing duration of the timer.
Specifically, as can be seen from the foregoing, the relay UE enters the active state to monitor SL between the remote UE and the relay UE, so as to ensure that the relay UE can successfully receive the message sent by the remote UE, thereby enabling the relay UE to successfully perform a relay function between the remote UE and the network device, and ensuring that a specific process requested by the remote UE can be successfully performed.
However, it should be noted that after the relay UE receives the first message sent by the remote UE, the relay UE will forward the first message to the network device first, receive a response message of the network device to the first message, and then send the response message to the remote UE, and receive a message returned by the remote UE. It can be seen that, after the relay UE receives the first message sent by the remote UE, it is not required to immediately receive the message from the remote UE, but it is required to receive the message from the remote UE after a period of time. Based on this, in one embodiment of the present disclosure, after the relay UE receives the first message sent by the remote UE, the relay UE may not immediately enter the active state, but may first time a period based on a timer, and when the timer expires, the relay UE delays entering the active state again, so that the time in which the relay UE is in the active state may be shortened, and the electric quantity is saved. Also, in one embodiment of the present disclosure, the timing duration of the timer satisfies the following condition: the timing duration is smaller than or equal to the shortest interval between two adjacent interactions between the relay UE and the remote UE, so that when the relay UE is delayed to enter the active state after the timer is overtime, the normal interaction between the relay UE and the remote UE is not influenced, and the communication stability of SL is ensured.
In summary, in the method for determining an activation state provided in the present disclosure, the network device configures a timing duration of a timer to the relay UE, so that the relay UE may determine a start time of an activation state of the relay UE based on the timing duration of the timer, and at the same time, the relay UE may determine a stop time of the activation state of the relay UE. In the present disclosure, when the remote UE requests a specific procedure, the relay UE enters an active state, and when the execution of the specific procedure requested by the remote UE is completed or is refused to be executed, the relay UE stops the active state. The relay UE is ensured to be in an activated state in the whole process of the specific flow requested by the remote UE, so that the condition that the specific flow requested by the remote UE is not completed yet and the relay UE enters the SL DRX sleep state is avoided, the on-time execution of the specific flow requested by the remote UE is ensured, the delay of the specific flow is avoided, and the communication stability of SL is ensured.
