[0026] To facilitate understanding, first introduce the terms related to the present disclosure.

[0027] 1. Remote terminal device

[0028] A terminal device can not be directly connected with a network device, but communicates with the network device through the relay of another device, for example, through another terminal device to communicate with the network device. Among them, the terminal device without connection with the network device is called a remote terminal device, and the terminal device providing relay function is called a relay terminal device. The remote terminal device and the relay terminal device communicate through sidelink unicast.

[0029] 2. Unified access control (UAC)

[0030] When a terminal device has a new access request, UAC verification is needed. The verification method is to select an access probability according to the access category (Access Category) and access identity (Access Identity) corresponding to the access request service. Then, a random number between 0 and 1 is generated. If the random number is lower than the access probability, the verification passes, and the access attempt can be initiated. If the random number is higher than the access probability, the verification fails, and the terminal device starts an access prohibition timer, such as T390. During the running of the prohibition timer, access is prohibited.

[0031] If the terminal device has cell reselection or cell selection during the running of the access prohibition timer, the running of the access prohibition timer can be stopped.

[0032] In order to better understand the method for access control disclosed in the embodiments of the present disclosure, the communication system to which the embodiments of the present disclosure are applicable is described first as follows.

[0033] Please refer to Figure 1 , Figure 1 The architecture of a communication system provided by the embodiments of the present disclosure is shown in FIG. 1. The communication system can include, but is not limited to, one network device and one terminal device. Figure 1 The number and form of devices shown in the figure are only for example and do not constitute a limitation on the embodiments of the present disclosure. In actual applications, two or more network devices and two or more terminal devices can be included. Figure 1 The communication system shown in the figure takes one network device 11, one remote terminal device 12 and one relay terminal device 13 as an example.

The CU-DU structure can split the protocol layer of the network device, such as the base station, and place part of the protocol layer functions in the CU for centralized control, and the remaining part or all of the protocol layer functions are distributed in the DU and controlled by the CU.

[0036] The remote terminal device 12 and the relay terminal device 13 in the embodiments of the present disclosure are an entity for receiving or transmitting signals on the user side, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, a wireless terminal device in smart home, etc. The embodiments of the present disclosure do not limit the specific technology and specific device form of the terminal device.

[0037] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0038] Generally, the relay selection of the remote terminal device can be triggered by the following two cases:

[0039] 1. The remote terminal device is a terminal device in a non-connected state, which moves from the coverage of a cell to the coverage of a relay terminal device. The non-connected state includes an idle state (RRC_IDLE) and an inactive state (RRC_INACTIVE).

[0040] 2. The remote terminal device leaves the connected state (RRC_CONNECTED). For example, radio link failure, handover failure, high-layer notification, etc.

[0041] In the present disclosure, for the case that the remote terminal device performs relay selection during the running of the access barring timer, how to control the running state of the access barring timer is proposed, and a method for access control is proposed, so that when the remote terminal device triggers relay selection, the access barring timer can be reasonably stopped, thereby ensuring that the remote terminal device can reliably access.

[0042] It should be noted that the method for access control provided by any of the embodiments in the present disclosure can be executed alone or in combination with the possible implementation methods in other embodiments, and can also be executed in combination with any of the technical solutions in the related art.

[0043] The method for access control and the device thereof provided by the present disclosure will be described in detail below in combination with the accompanying drawings.

[0044] Please refer to Figure 2 , Figure 2 is a flowchart of a method for access control provided by an embodiment of the present disclosure, and the method is executed by a remote terminal device. As shown in Figure 2 , the method can include but is not limited to the following steps:

[0045] Step 201, in response to the remote terminal device performing relay selection during the running of the access barring timer, determining the satisfaction of the specified condition.

[0046] Optionally, the specified condition can be that the trigger event of the relay selection is a specified event, or the serving cell in which the remote terminal device is located changes.

[0047] Optionally, the trigger event of the relay selection can be that the remote terminal device moves from the coverage range of a cell to the coverage range of a relay terminal device, or the remote terminal device leaves the connected state, such as handover failure, radio link failure, etc.

[0048] Optionally, the remote terminal device performing relay selection can mean that the remote terminal device moves from the coverage range of a cell to the coverage range of a relay terminal device, thereby performing relay selection.

[0049] Alternatively, the remote terminal device also performs relay reselection when the remote terminal device performs relay selection. For example, when the relay terminal device experiences radio link failure, handover, cell reselection, radio resource control (RRC) connection failure, the relay terminal device sends a notification message (Notification Message Sidelink) to the connected remote terminal device through the sidelink. After the remote terminal device receives the notification message, if the remote terminal device is in an idle state or an inactive state, the remote terminal device can perform relay reselection.

[0050] In step 202, the running state of the access barring timer is controlled according to the satisfaction of the specified condition.

[0051] In the present disclosure, if the remote terminal device performs relay selection during the running of the access barring timer, the satisfaction of the specified condition can be determined first, and then whether the access barring timer can be stopped is determined according to the current satisfaction of the specified condition.

[0052] Optionally, the remote terminal device can determine whether the access barring timer can be stopped according to whether the triggering event of the relay selection in the specified condition is a specified event, or whether the serving cell of the remote terminal device changes.

[0053] That is, if the remote terminal device performs relay selection during the running of the access barring timer, the remote terminal device can stop the access barring timer according to the satisfaction of the specified condition, and then can perform random access, or can keep the access barring timer running.

[0054] In the present disclosure, if the remote terminal device performs relay selection during the running of the access barring timer, the satisfaction of the specified condition is determined first, and then the running state of the access barring timer is controlled according to the satisfaction of the specified condition, thereby realizing reliable control of random access of the remote terminal device. Therefore, the remote terminal device can reasonably stop the access barring timer and perform random access, thereby ensuring the reliability of communication of the remote terminal device.

[0055] Please refer to Figure 3 , Figure 3 is a flowchart of another access control method provided by an embodiment of the present disclosure, which is performed by a remote terminal device. As shown in Figure 3 , the method can include but is not limited to the following steps:

[0056] In step 301, in response to the remote terminal device performing relay selection during the running of the access barring timer, the satisfaction of the specified condition is determined.

[0057] The specific implementation of step 301 can refer to the detailed description of any embodiment of the present disclosure, which will not be repeated here.

[0058] Step 302, in response to the specified condition being met, stopping the access barring timer.

[0059] Optionally, the specified condition can include any of the following: the relay selection trigger event is a specified event, the serving cell of the remote terminal device changes.

[0060] For example, if the specified condition is that the relay selection trigger event is a specified event, if the remote terminal device triggers relay selection during the running of the access barring timer, it can be determined whether the event triggering the relay selection is a specified event, if so, it can be determined that the specified condition is met, and then the access barring timer can be stopped for random access.

[0061] Optionally, the specified event can be any one or more of the following: leaving the connected state, radio link failure, cell handover failure, receiving an RRC release message, and high layer notification.

[0062] The high layer notification can be a notification from the application layer of the remote terminal device, such as an application layer notification to the remote terminal device to perform relay selection or relay reselection.

[0063] Alternatively, the remote terminal device can also perform relay selection during the running of the access barring timer, first determine the serving cell it is currently in, and then determine whether the serving cell it is currently in is the same as the serving cell it was in before performing relay selection, if not, it means that the serving cell has changed, i.e. the specified condition is met, and the remote terminal device can stop the access barring timer to perform random access.

[0064] Optionally, the remote terminal device can perform relay selection during the running of the access barring timer, first determine whether the trigger event of the relay selection meets the specified condition, if so, stop the access barring timer. If not, determine whether the serving cell it is in has changed, if so, stop the access barring timer.

[0065] Alternatively, the remote terminal device can also perform relay selection during the running of the access barring timer, first determine whether the serving cell it is in has changed, if so, stop the access barring timer. If not, determine whether the trigger event of the relay selection meets the specified condition, if so, stop the access barring timer, and so on, which is not limited by the present disclosure.

[0066] In the present disclosure, the remote terminal device can stop the access barring timer and perform random access if the remote terminal device performs relay selection during running of the access barring timer and the trigger event of the relay selection is a specified event or the serving cell of the remote terminal device changes. Thus, the remote terminal device can reasonably stop the access barring timer and perform random access, and the reliability of communication of the remote terminal device is ensured.

[0067] Please refer to Figure 4 , Figure 4 is a flowchart of another access control method provided by an embodiment of the present disclosure, which is performed by a remote terminal device. As shown in Figure 4 , the method can include but is not limited to the following steps:

[0068] Step 401: In response to the remote terminal device performing relay selection during running of the access barring timer, determine whether a specified condition is met.

[0069] The specific implementation of step 401 can refer to the detailed description of any embodiment of the present disclosure, which will not be repeated here.

[0070] Step 402: In response to the specified condition not being met, keep the access barring timer running.

[0071] Optionally, the specified condition can include any of the following: the trigger event of the relay selection is a specified event, and the serving cell of the remote terminal device changes.

[0072] For example, if the specified condition is that the trigger event of the relay selection is a specified event, and the remote terminal device triggers the relay selection during running of the access barring timer, it can be determined whether the event triggering the relay selection is a specified event. If not, it can be determined that the specified condition is not met, and the access barring timer can be kept running.

[0073] Optionally, the specified event can be any one or more of the following: leaving the connected state, radio link failure, cell handover failure, receiving an RRC release message, and high-layer notification.

[0074] The high-layer notification can be a notification of an application layer of the remote terminal device, such as an application layer notifying the remote terminal device to perform relay selection or relay reselection.

[0075] Alternatively, the remote terminal device can first determine the serving cell in which it is currently located after performing relay selection during the running of the access barring timer, and then determine whether the serving cell in which it is currently located is the same as the serving cell in which it was located before performing relay selection. If they are the same, it indicates that the serving cell in which it is located has not changed, i.e., the specified condition is not met, and the remote terminal device can keep the access barring timer running, i.e., not perform random access.

[0076] Alternatively, the remote terminal device can first determine whether the trigger event of relay selection meets the specified condition after performing relay selection during the running of the access barring timer. If it does not meet the specified condition, it continues to determine whether the serving cell in which it is located has changed. If it has not changed, it keeps the access barring timer running.

[0077] Alternatively, the remote terminal device can first determine whether the serving cell in which it is located has changed after performing relay selection during the running of the access barring timer. If it has not changed, it determines whether the trigger event of relay selection meets the specified condition. If it does not meet the specified condition, it keeps the access barring timer running, and so on. The present disclosure does not limit this process.

[0078] In the present disclosure, if the remote terminal device performs relay selection during the running of the access barring timer, the trigger event of relay selection is not the specified event, or the serving cell in which the remote terminal device is located has not changed, the access barring timer can be kept running, thereby avoiding the remote terminal device from performing random access. Thus, the present disclosure achieves reasonable control of the running of the access barring timer by the remote terminal device, reliable control of random access, and ensures the reliability of communication of the remote terminal device. Please refer to Figure 5 , Figure 5 is a flowchart of another method of access control provided by an embodiment of the present disclosure. The method is performed by a remote terminal device. As shown in Figure 5 , the method can include but is not limited to the following steps:

[0079] Step 501: In response to the remote terminal device performing relay selection during the running of the access barring timer, determining whether the specified condition is met.

[0080] Step 502: In response to the specified condition being met, stopping the access barring timer.

[0081] The specific implementation of the above steps 501 and 502 can refer to the detailed description of any embodiment of the present disclosure, which will not be described here.

[0082] Step 503: In response to the specified condition not being met, keeping the access barring timer running.

[0083] Optionally, the relay selection of the remote terminal device can mean that the remote terminal device moves from the coverage of a cell to the coverage of a relay terminal device, thereby performing relay selection. Alternatively, the remote terminal device can also perform relay reselection.

[0084] Optionally, the specified condition can include any of the following: the trigger event of the relay selection is a specified event, and the serving cell of the remote terminal device changes.

[0085] For example, if the specified condition is that the trigger event of the relay selection is a specified event, if the remote terminal device triggers the relay selection during the running of the access barring timer, it can be determined whether the trigger event of the relay selection is a specified event, if yes, the access barring timer can be stopped to perform random access; if no, the access barring timer can continue to run, i.e. no random access is performed.

[0086] Optionally, the specified event can be any one or more of the following: leaving the connected state, radio link failure, cell handover failure, receiving an RRC release message, and high-layer notification.

[0087] The high-layer notification can be a notification of an application layer of the remote terminal device, such as an application layer notifying the remote terminal device to perform relay selection or relay reselection.

[0088] Alternatively, if the specified condition is that the serving cell of the remote terminal device changes, if the remote terminal device performs cell selection during the running of the access barring timer and the serving cell does not change, the remote terminal device can continue to run the access barring timer, i.e. no random access is performed. If the serving cell changes, the remote terminal device can stop the access barring timer to perform random access.

[0089] Optionally, after the remote terminal device performs relay selection during the running of the access barring timer, it can first determine whether the trigger event of the relay selection meets the specified condition, if yes, the access barring timer is stopped. If no, it is determined whether the serving cell changes, if yes, the access barring timer is stopped. If no, the access barring timer continues to run.

[0090] Alternatively, the remote terminal device can also first determine whether the serving cell changes after it performs relay selection during the running of the access barring timer, if yes, the access barring timer is stopped. If no, it is determined whether the trigger event of the relay selection meets the specified condition, if yes, the access barring timer is stopped. If no, the access barring timer continues to run, which is not limited by the present disclosure.

[0091] In the present disclosure, if the remote terminal device makes relay selection during running of the access barring timer, the remote terminal device can determine whether a specified condition is met, and if so, the access barring timer can be stopped, otherwise, the access barring timer continues to run. In this way, the remote terminal device can reasonably stop and run the access barring timer, thereby ensuring that the remote terminal device can reasonably perform random access, and ensuring the reliability of remote terminal device communication.

[0092] Please refer to Figure 6 A structural schematic diagram of a communication apparatus 600 is provided for the embodiments of the present disclosure. Figure 5 The communication apparatus 600 shown can include a processing module 601.

In this way, the remote terminal device can reasonably stop the access barring timer and perform random access, thereby ensuring the reliability of communication of the remote terminal device.
