Description

[Technical field]

[0001] The present disclosure relates to the field of communication technologies, and in particular to a connection establishment method, a connection establishment device, an electronic device, and a computer-readable storage medium. [Background technology]

[0002] The terminal can perform an action such as connection establishment, connection recovery, or connection re-establishment by sending a request to the base station, which can carry the cause of the action. Depending on the cause, the base station can allow the action to be performed by the terminal or deny the action to be performed by the terminal.

[0003] In some scenarios, when a terminal communicates with a base station, it can achieve communication with the base station via a relay device rather than establishing a direct communication connection with the base station, in which case the terminal can be referred to as a remote device.

[0004] Because the far-end device and the base station do not communicate directly, when the far-end device performs operations such as connection establishment, connection recovery, and connection re-establishment, the far-end device sends requests to the relay device rather than sending requests to the base station, and further, the relay device can send requests to the base station to perform operations such as connection establishment and connection recovery with the base station to support communication between the far-end device and the base station.

[0005] In this case, based on the current relay communication architecture, the relay device cannot see the cause of the communication action performed by the far-end device, and thus, although the relay device can convey the cause in the request sent to the base station, it is not necessarily the same as the cause conveyed by the far-end device in the request sent to the relay device, thereby making it impossible for the base station to accurately determine the cause of the far-end device performing actions such as connection establishment, connection recovery, and connection re-establishment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The following clearly and completely describes the technical solutions in the embodiments of the present disclosure in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present disclosure.

[0016] FIG. 1 is a flowchart of a connection establishment method shown by an embodiment of the present disclosure. The connection establishment method shown in this embodiment can be applied to a terminal, and the terminal can act as a relay device of a relay function, and the terminal includes, but is not limited to, electronic devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with a base station as a user equipment, and can also provide a relay function to a far-end device and a base station as a relay device, and can transmit information from the far-end device to the base station, and the base station includes, but is not limited to, a 4G base station, a 5G base station, and a 6G base station. In one embodiment, the far-end device is a far-end device applicable to the connection establishment method described in any of the following embodiments.

[0017] As shown in FIG. 1, the connection establishment method may include the following steps: In step S101, in response to receiving connection-related information of the far-end device, the relay device determines a reason for establishing or recovering a connection with the base station based on the connection-related information, and the connection-related information is used to indicate a connection request of the far-end device.

[0018] In one embodiment, when the relay device is in a disconnected state, the far end device can trigger a connection establishment or a connection restoration between the relay device and the base station by sending connection related information to the relay device, the connection related information can indicate a connection request of the far end device. For example, when the relay device is in an idle state, a connection establishment can be triggered, and when the relay device is in an inactive state, a connection restoration can be triggered.

[0019] In one embodiment, the connection request comprises: The request includes at least one of a connection establishment request, a connection re-establishment request, and a connection restoration request.

[0020] In one embodiment, the relay device and the far-end device can communicate via a sidelink (which can also be translated as a secondary link, side link, edge link, etc.).

[0021] In one embodiment, the far-end device transmits connection-related information to the relay device based on the communication operation to be performed as required, and the connection-related information may differ depending on the communication operation to be performed, and the cause of the connection request indicated by the connection-related information may be multiple.

[0022] For example, the far-end equipment needs to perform a connection establishment, the connection-related information may indicate a connection establishment request, and the connection establishment request may convey the cause of the connection establishment.

[0023] In one embodiment, the cause of the connection request is: These include, but are not limited to, emergency, high priority access, user initiated data, user initiated voice call, user initiated video call, user initiated signaling, incoming call, etc.

[0024] If the base station can directly receive a connection request corresponding to the communication operation of the far-end device, such as the above-mentioned connection establishment request, it can accurately determine the reason why the far-end device performs the communication operation, and can accurately make a decision to allow the far-end device to perform the communication operation or to deny the far-end device from performing the communication operation.

[0025] However, since the far-end device communicates with the base station via a relay device, the far-end device needs to send a request corresponding to the communication operation to the relay device when performing a communication operation, and the base station cannot directly receive the request corresponding to the communication operation sent by the far-end device. In the related technology, the cause of the communication operation performed by the far-end device is not visible to the relay device.

[0026] After receiving a request corresponding to the communication operation sent by the far-end device, the relay device can establish a connection or restore a connection with the base station, and further sends a connection establishment request or a connection restoration request to the base station. Since the relay device cannot determine the cause of the communication operation sent by the far-end device, the relay device sets a connection establishment cause or a connection restoration cause according to its own implementation, so that the cause carried in the connection establishment request or connection restoration request is different from the cause of the far-end device performing the communication operation, and further, the base station cannot accurately determine the cause of the far-end device performing the communication operation, and erroneously makes a decision to allow the relay device to establish a connection or restore a connection, or a decision to reject the relay device's establishment of a connection or restore a connection.

[0027] According to an embodiment of the present disclosure, the relay device can trigger connection establishment or connection recovery after receiving the connection-related information sent when the far-end device needs to perform a communication operation, and can determine the cause of the connection establishment or connection recovery that the relay device itself needs to perform based on the connection-related information of the far-end device, the connection-related information can indicate a connection request of the far-end device, and the connection request corresponds to the communication operation that the far-end device needs to perform, so that the cause of the relay device performing the connection establishment or connection recovery corresponds to the cause of the far-end device performing the communication operation, for example, the cause carried in the connection establishment request or connection recovery request corresponds to the cause of the connection-related information for the far-end device performing the communication operation, and further, the base station can accurately determine the cause of the far-end device performing the communication operation based on the cause of the relay device performing the connection establishment or connection recovery, which is advantageous for the base station to accurately make a decision to allow the relay device to perform the connection establishment or connection recovery, or a decision to reject the connection establishment or connection recovery of the relay device.

[0028] The following describes the embodiments of the present disclosure based on specific examples. For example, the base station may establish priorities for different causes and, in some scenarios, make a grant decision only for communication operations corresponding to causes with higher priority and a denial decision for communications corresponding to causes with lower priority.

[0029] Taking four causes as examples: emergency, user initiated data, user initiated signaling, and incoming call, the order of priority from highest to lowest is emergency, user initiated signaling, user initiated data, and incoming call.

[0030] In some scenarios, the base station makes an authorization decision for communication operations corresponding to two causes, emergency and user initiated signaling, and makes a denial decision for communication operations corresponding to user initiated data and incoming calls.

[0031] In order for the far-end device to communicate with the base station via the relay device, it needs to perform connection restoration and send connection-related information to the relay device, where the connection-related information can indicate a connection restoration request, and the connection restoration request carries the cause of the connection restoration, which is user-initiated signaling.

[0032] In the related technology, the far-end device sends a connection restoration cause carried by a connection restoration request of the relay device, which is invisible to the relay device, and the relay device initiates a connection establishment or connection restoration operation, determines the cause of the connection establishment or connection restoration operation according to its own situation, for example, initiates a connection establishment operation and sends a connection establishment request to a base station, and the connection establishment request carries the cause of the connection establishment, which is an incoming call.

[0033] In the related technology, after the base station receives a connection establishment request sent by a relay device, the base station determines that the cause of the incoming call is the cause of the connection establishment of the relay device and makes a refusal decision, i.e., if the relay device refuses to establish the connection, the far-end device also cannot restore the connection through the relay device, and the far-end device will fail to communicate with the base station.

[0034] According to an embodiment of the present disclosure, the relay device can determine based on the connection-related information that the far-end device performs connection restoration and that the cause of the connection restoration is user-initiated signaling, thereby enabling the relay device to determine that the cause of the connection establishment is user-initiated signaling, and further, in the connection establishment request sent to the base station, the cause of the connection establishment carried is user-initiated signaling.

[0035] According to an embodiment of the present disclosure, after the base station receives a connection establishment request sent by the relay device, it causes the establishment of the relay device through user-initiated signaling, and thereby makes an authorization decision, i.e., allows the relay device to perform the connection establishment, so that the far-end device can perform connection restoration through the relay device, thereby ensuring the successful communication of the far-end device with the base station.

[0036] 2 is a flowchart of another connection establishment method according to an embodiment of the present disclosure. As shown in FIG. 2, in some embodiments of the present disclosure, the step of determining a reason for the relay device to establish or recover a connection with a base station based on the connection-related information includes step S201: In step S201, connection establishment is triggered by connection-related information of the far-end device, the connection-related information indicates a connection restoration request of the far-end device, and in response to the cause in the connection restoration request being a Radio Access Network (RAN) domain update, the relay device determines that the cause for establishing a connection with a base station is a first cause, and the first cause is related to the RAN domain update.

[0037] In one embodiment, when the far-end device is in an inactive state and the relay device is in an idle state, the communication operation performed by the far-end device to communicate with the base station may be connection restoration, entering a connection state from the inactive state, and the far-end device can send connection-related information to the relay device, and the connection-related information is used to indicate the connection restoration request of the far-end device, triggering the relay device to perform connection establishment and sending a connection establishment request to the base station.

[0038] The cause of connection restoration may be partly the same as the cause of connection establishment, such as the above-mentioned emergency, high priority access, user initiated data, user initiated voice call, user initiated video call, user initiated signaling, incoming call, etc., but the difference is that the cause of connection restoration may also be a RAN domain update, which is a specific cause of connection restoration, and the cause of connection establishment is not a RAN domain update.

[0039] Since the cause of the connection establishment of the relay device is not the RAN domain update, and the cause of the connection recovery of the far end device is the RAN domain update, in this embodiment, the cause of the connection establishment of the relay device can be set as the first cause, and the first cause can be related to the RAN domain update. Thus, when the relay device establishes a connection, the cause of the connection establishment cannot be directly set to the RAN domain update, but is set to the cause related to the RAN domain update, so that the base station can relatively accurately determine that the communication operation that the far end device needs to perform is the connection recovery, and the cause of the connection recovery is the RAN domain update.

[0040] In one embodiment, the first cause is user-initiated signaling. The far end performs connection recovery based on the cause of the RAN domain update, and after the connection recovery, the communication between the far end and the base station can mainly be user-initiated signaling, so even if the relay device cannot set the cause of the connection establishment to the RAN domain update, the cause of the connection establishment can be set to the user-initiated signaling related to the subsequent communication of the RAN domain update, and the base station can determine to some extent the cause of the far end performing connection recovery based on the connection establishment request sent by the relay device.

[0041] 3 is a flowchart of another connection establishment method according to an embodiment of the present disclosure. As shown in FIG. 3, in some embodiments of the present disclosure, the step of determining a reason for the relay device to establish or recover a connection with a base station based on the connection-related information includes step S301: In step S301, in response to the connection-related information indicating a connection re-establishment request from the far-end device, it is determined that the cause of the relay device establishing or recovering the connection is a second cause, the second cause being related to the connection re-establishment.

[0042] In one embodiment, when the far-end device is in a connected state but communication with the base station is interrupted for some reason and the relay device is in a disconnected state, the communication operation performed by the far-end device to communicate with the base station may be connection re-establishment to maintain the connected state and continue to communicate with the base station, and the far-end device can send connection-related information to the relay device, and the connection-related information indicates a connection re-establishment request of the far-end device, triggers the relay device to establish or recover the connection, and sends a connection establishment request or a connection recovery request to the base station.

[0043] Since connection re-establishment is an operation performed in a connected state, and connection establishment or connection recovery is an operation performed in a non-connected state, the cause of connection re-establishment is fundamentally different from the cause of connection establishment or connection recovery, that is, when a relay device performs connection establishment or connection recovery, the cause conveyed in the connection establishment request or connection recovery request is not a cause related to connection re-establishment.

[0044] Because the cause of the connection establishment or recovery of the relay device is not a cause related to the connection re-establishment, in this embodiment, the cause of the connection establishment of the relay device can be set to the second cause, and the first cause can be related to the connection re-establishment, so that when the relay device performs the connection establishment, the cause of the connection establishment or recovery cannot be directly set to the cause related to the connection re-establishment, but can be set to the cause related to the connection re-establishment, and the base station can relatively accurately determine that the communication operation performed by the far end device is the connection re-establishment and the cause related to the connection re-establishment.

[0045] In one embodiment, the second cause is user-initiated data. After the far-end device performs the connection re-establishment, the communication between the far-end device and the base station can be mainly user-initiated data, so even if the relay device cannot set the cause of the connection establishment or the connection recovery to the cause of the connection re-establishment, the cause of the connection establishment or the connection recovery can also be set to the user-initiated data related to the subsequent communication of the connection re-establishment, and the base station can determine the cause of the connection re-establishment of the far-end device based on the connection establishment request or the connection recovery request sent by the relay device to some extent.

[0046] In one embodiment, the second cause is re-establishment. When the relay device triggers the connection establishment or connection recovery by the communication operation of the far-end device, even if the cause of the connection establishment or connection recovery cannot be set to the cause of the connection re-establishment, it can determine that the far-end device needs to perform re-establishment, and therefore, by setting the second cause to the re-establishment, the base station can determine that the relay device performs the connection establishment or connection recovery because the far-end device needs to perform the connection re-establishment.

[0047] This cause of re-establishment belongs to a new established cause, which is different from the currently existing causes such as emergency, high priority access, user initiated data, user initiated voice call, user initiated video call, user initiated signaling, incoming call, etc., and for this cause of re-establishment, the base station can make an allow or deny decision on the connection-related information of the cause as necessary.

[0048] It can be determined that the far-end equipment needs to communicate with the base station via a relay equipment, and then it can be determined that the cause of the triggered connection establishment or connection recovery is relaying, and this cause of relaying belongs to a new established cause and is different from the current already-existing causes such as emergency, high priority access, user-initiated data, user-initiated voice call, user-initiated video call, user-initiated signaling, incoming call, etc., and for this cause of relaying, the base station can make an allow or deny decision on the connection-related information of the cause as necessary.

[0049] 4 is a flowchart of another connection establishment method according to an embodiment of the present disclosure. As shown in FIG. 4, in some embodiments of the present disclosure, the step of determining a reason for the relay device to establish or recover a connection with a base station based on the connection-related information includes step S401: In step S401, the cause of connection establishment or connection recovery is determined based on the cause in the connection request of the far-end device indicated in the connection related information initiated by the far-end device.

[0050] In one embodiment, the cause of a communication operation initiated by a far-end device can be determined, for example, the far-end device can send connection-related information to an intermediate device, the connection-related information indicating a connection request for the far-end device, the connection request can carry the cause of the communication operation initiated by the far-end device, and further, the cause of the connection establishment or connection restoration of the intermediate device can be directly determined based on the cause of the communication operation initiated by the far-end device.

[0051] In one embodiment, the step of determining a cause for connection establishment or recovery based on a cause in a connection request of the far-end device indicated in the connection related information comprises: The method includes a step of determining, by the relay device, a cause in the connection request of the far-end device indicated by the connection-related information as a cause for establishing or recovering a connection.

[0052] In one embodiment, the cause of the connection request of the far-end device indicated in the connection-related information initiated by the far-end device, i.e., the cause of the communication operation performed by the far-end device, is taken as the cause of connection establishment or connection recovery of the relay device, so that when the relay device sends a connection establishment request or connection recovery request to the base station, the cause of the communication operation can be conveyed, and the base station can determine connection establishment or connection recovery of the relay device based on the cause of the communication operation performed by the far-end device.

[0053] 5 is a flowchart of another connection establishment method according to an embodiment of the present disclosure. As shown in FIG. 5, in some embodiments of the present disclosure, the step of determining a reason for the relay device to establish or recover a connection with a base station based on the connection-related information includes steps S501 to S502; In step S501, a service type corresponding to a connection request of the far-end device indicated by the connection-related information is determined; In step S502, the cause of connection establishment or recovery is determined based on the service type.

[0054] In one embodiment, after the relay device receives the connection-related information sent by the far-end device, it can determine a service type corresponding to a connection request of the far-end device indicated in the connection-related information of the far-end device, i.e., a service type corresponding to a communication operation performed by the far-end device, where the service type includes, but is not limited to, an emergency call, data, voice, etc. Furthermore, it can determine a cause of connection establishment or connection recovery based on the service type, for example, the service type may be an emergency call and the determined cause may be emergency, for example, the service type may be data and the determined cause may be data initiated by a user, for example, the service type may be voice and the determined cause may be a voice call initiated by a user.

[0055] This also allows the relay device to determine the cause of connection establishment or restoration even if the far-end device does not send a connection request for a communication operation to the relay device or does not convey the cause of the communication operation in the connection request.

[0056] In addition, even if the cause of the communication operation is conveyed in the connection request for the communication operation sent by the relay device to the far-end device, the relay device can also determine the cause of the connection establishment or connection recovery based on the service type. Specifically, the relay device can determine the cause of the connection establishment or connection recovery based on the cause for the communication operation performed by the far-end device, or based on the service type, or based on the implementation of the relay device.

[0057] 6 is a flowchart of another connection establishment method according to an embodiment of the present disclosure. As shown in FIG. 6, in some embodiments of the present disclosure, the step of determining a reason for the relay device to establish or recover a connection with a base station based on the connection-related information includes step S601: In step S601, The cause of the intermediate device establishing or recovering a connection is It is determined to be a relay.

[0058] In one embodiment, after the relay device receives the connection-related information sent by the far-end device, it can trigger connection establishment or connection recovery, and can further determine that the far-end device needs to communicate with the base station through the relay device, and then it can determine that the cause of the triggered connection establishment or connection recovery is relaying, so that the base station can determine that the relay device performs connection establishment or connection recovery so as to provide relaying for the far-end device.

[0059] This cause of relaying belongs to a new established cause and is different from the currently existing causes such as emergency, high priority access, user initiated data, user initiated voice call, user initiated video call, user initiated signaling, incoming call, etc., and for this cause of relaying, the base station can decide to make an allow or deny decision for the communication operation of the cause as necessary.

[0060] In one embodiment, The cause of the intermediate device establishing or recovering a connection is The step of determining that the node is a relay includes: The above The cause of the intermediate device establishing or recovering a connection is determining that the far-end device is to relay for the far-end device.

[0061] In one embodiment, the cause of the connection establishment or connection recovery of the relay device can be determined, specifically, relaying for the far-end device, so that the base station can clarify that the relay device provides relaying for the far-end device, and the base station can determine whether to allow the connection establishment or connection recovery of the relay device based on the far-end device, for example, if the relay device provides relaying to the far-end device, the connection establishment or connection recovery of the relay device is allowed, and if the relay device does not provide relaying to the far-end device, the connection establishment or connection recovery of the relay device is not allowed.

[0062] 7 is a flowchart of another connection establishment method according to an embodiment of the present disclosure. As shown in FIG. 7, in some embodiments of the present disclosure, the connection establishment method may further include step S701: In step S701, when sending a connection establishment request or a connection recovery request to a base station, the cause is sent to the base station.

[0063] In one embodiment, when the relay device sends a connection establishment request or a connection recovery request to the base station, the cause can be transmitted to the base station, for example, carried in the connection establishment request or the connection recovery request and transmitted to the base station, so that the base station determines the connection establishment or connection recovery of the relay device based on the cause of the far-end device performing the communication operation.

[0064] FIG. 8 is a flowchart of a connection establishment method shown by an embodiment of the present disclosure. The connection establishment device shown in this embodiment can be applied to a terminal, and the terminal can communicate with a base station as a user equipment, and can also communicate with a base station through a relay device as a far-end device, and the terminal includes, but is not limited to, electronic devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The base stations include, but are not limited to, 4G base stations, 5G base stations, and 6G base stations. In one embodiment, the relay device is a relay device to which the connection establishment method described in any of the above embodiments is applied.

[0065] As shown in FIG. 8 , the cause determination sending may include step S801; In step S801, in response to communicating with a base station via a relay device, transmitting the connection related information to the relay device, the connection related information being used to indicate a connection request of the far-end device.

[0066] In one embodiment, the relay device and the far-end device can communicate via a sidelink (which can also be translated as a secondary link, side link, edge link, etc.).

[0067] According to an embodiment of the present disclosure, when a far-end device needs to perform a communication operation with a base station through a relay device, the connection-related information can be sent to the relay device, on the one hand, the relay device can trigger an operation of performing connection establishment or connection recovery by the relay device, on the other hand, the connection-related information can indicate a connection request of the far-end device, the connection request corresponds to the communication operation that the far-end device needs to perform, so that the relay device can determine the reason why the far-end device performs the communication operation, and the relay device itself determines the reason why the relay device performs the connection establishment or connection recovery according to the communication operation of the far-end device, the reason why the relay device performs the connection establishment or connection recovery corresponds to the reason why the far-end device performs the communication operation, for example, the cause carried in the connection establishment request or the connection recovery request corresponds to the reason why the far-end device performs the communication operation, and further, the base station can accurately determine the reason why the far-end device performs the communication operation according to the reason why the relay device performs the connection establishment or connection recovery, which is advantageous for the base station to accurately make a decision to allow the relay device to perform the connection establishment or connection recovery, or to reject the relay device to perform the connection establishment or connection recovery.

[0068] In one embodiment, the connection request comprises: The request includes at least one of a connection establishment request, a connection re-establishment request, and a connection restoration request.

[0069] 9 is a flowchart of another connection establishment method according to an embodiment of the present disclosure.
