[0159] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0160] As shown in FIG1 , a communication system 100 includes a relay device 101 , an access network device 102 , and a core network device 103 .

[0161] In some embodiments, the relay device 101 is, for example, a device for relaying signals or data, and can serve as a bridge connecting different base stations or nodes. The relay device can be at least one of a relay node, a relay antenna, and a relay device module, but is not limited thereto.

[0162] In some embodiments, the access network device 102 is, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an integrated access backhaul base station (IAB-donor), an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0163] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0164] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0165] In the IAB architecture, access network equipment can be provided as an IAB-donor. An IAB-donor can include one IAB-donor-CU and one or more IAB-donor-DUs. When the gNB-CU-CP and gNB-CU-UP are separated, the IAB-donor may include one IAB-donor-CU-CP, multiple IAB-donor-CU-UPs, and multiple IAB-donor-DUs.

The IAB-node provides wireless backhaul to downstream IAB-nodes and terminal devices via network functionality over the NR Uu interface (referred to as the IAB-DU functionality within the IAB-node).

[0166] In the embodiments of the present disclosure, the first node 1021 and the second node 1022 of the access network device are mainly involved.

Optionally, the first node 1021 can be a radio resource control terminating base station (Radio Resource Control-terminating-IAB-donor, RRC-terminating-IAB-donor or RRC-terminating-donor), which can also be called a non-F1 terminating base station (non-F1-terminating-IAB-donor or non-F1-terminating-donor), and the second node 1022 can be an F1 terminating base station (F1-terminating-IAB-donor or F1-terminating-donor).

[0172] Figure 2 is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiment of the present disclosure relates to an information processing method, which includes the following steps.

[0173] Step S2101: The relay device sends indication information to the first node of the access network device.

[0174] In some embodiments, the indication information may be used to indicate the node type of the relay device, and the relay device may send the indication information to the first node of the access network device according to its node configuration.

[0175] The node configuration may be a registration procedure pre-defined for the relay device, and the relay device may determine whether its node type is the first node type or the second node type according to its node configuration, thereby sending indication information based on the determined node type.

[0176] In some embodiments, the indication information may be used to indicate at least one of the first node type and the second node type. That is, the relay device may send the indication information to the first node as either the first node type or the second node type. In this case, the indication information may be used to indicate either the first node type or the first node type. Alternatively, the relay device may send the indication information to the first node as either the first node type or the second node type. In this case, the indication information may be used to indicate both the first node type and the second node type.

[0177] For example, if the relay device supports the first node type, the relay device may send indication information as the first node type; or, if the relay device supports the second node type, the relay device may send indication information as the second node type. For another example, if the relay device supports both the first node type and the second node type, the relay device may send indication information as the second node type; or, the relay device may send indication information as either the first node type or the second node type.

[0178] Optionally, the relay device supports both the first node type and the second node type, but the relay device can only send indication information as one node type. In this case, the relay device may give priority to sending indication information as the second node type.

[0179] In some embodiments, the first node type is a relay node type, and the second node type is a mobile relay node type. In some embodiments, the first node type is a node type that supports multi-hop transmission, and the second node type is a node type that does not support multi-hop transmission.

[0180] In some embodiments, the first node type may be an IAB node type, and the second node type may be a Mobile Integrated Access and Backhaul (mIAB) node type.

[0181] Optionally, if the relay device is an IAB node type, the relay device can establish a communication connection with the core network device as an IAB node. The relay device can support multi-hop (Multi-Hop) functionality, so the relay device can access other IAB nodes (IAB-node). If the relay device is an mAB node type, the relay device can establish a communication connection with the core network device as an mAB node. The relay device cannot support multi-hop transmission, so other mAB nodes cannot access the relay device, and the relay device cannot access other mAB nodes.

[0182] In some embodiments, other functions used by the IAB node and the mAIB node may also be different. Generally speaking, the mAIB node supports more functions than the IAB node. However, both the IAB node and the mAIB node can provide access services for other terminal devices.

[0183] In some embodiments, the relay device may be an IAB-node or a mobile IAB-node.

[0184] In some embodiments, the IAB-MT in the IAB-node or the mobile IAB-MT in the mobile IAB-node sends the indication information to the first node through a Radio Resource Control (RRC) message.

[0185] In some embodiments, the first node may be an integrated access backhaul base station (IAB-donor), which is a serving base station of an IAB-MT or a mobile IAB-MT.

[0186] In some embodiments, the first node may be a host node corresponding to the terminal part of the relay device (i.e., the relay device is an IAB-node or a mobile IAB-node, and the first node is an IAB-donor of an IAB-MT or an IAB-donor of a mobile IAB-MT). The first node may be used to manage the context (Context) of the terminal part of the relay device. For example, the first node may be a radio resource control terminating base station (RRC-terminating-IAB-donor or RRC-terminating-donor), and may also be called a non-F1 terminating base station (non-F1-terminating-IAB-donor or non-F1-terminating-donor). The embodiment of the present disclosure does not limit the name of the first node.

[0187] In some embodiments, the context of the terminal portion of the relay device may be managed by the control unit of the first node.

[0188] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0189] Step S2102: The first node sends indication information to the core network device.

[0190] In some embodiments, the first node may receive indication information sent by the relay device, and send the received indication information to the core network device.

[0191] Optionally, in some embodiments, the relay device does not send the indication information to the first node, and the first node may directly determine the indication information. That is, the first node may not obtain the node type of the relay device, but may directly query the core network device to determine the authorized node type. The core network device may include multiple network elements. Optionally, the first node may send the indication information to a first network element of the core network device, which may be an Access and Mobility Management Function (AMF).

[0192] Step S2103: The core network device obtains fourth information based on the indication information.

[0193] In some embodiments, the core network device may receive indication information sent by the first node, thereby obtaining fourth information based on the received indication information. The fourth information may be used to indicate authorization information provided by the core network device for the node type of the relay device. Optionally, the authorization information of the node type may be used to indicate whether the relay device is authorized to provide connection services in the network as a node type. Furthermore, the authorization information of the node type is used to indicate that the relay device has the authority to provide connection services in the network as a node type. The connection service includes providing relay transmission for other relay devices or terminal devices.

[0194] In some embodiments, the fourth information may be obtained based on the node type indicated by the indication information, wherein the indication information may include one or more node types.

[0195] Optionally, the indication information includes one or more node types, and the authorized node type of the fourth information may be determined to be one of the node types.

[0196] For example, if the indication information includes one node type, then this node type can be directly used as the authorized node type of the fourth information. For another example, if the indication information includes multiple node types, then the authorized node type of the fourth information can be determined to be the node type with the highest authority.

[0197] Among them, the level of authority of the node type can be determined based on the number of functions supported by the node. Taking the first node type as the IAB node type and the second node type as the mAB node type as an example, compared with the IAB node type, the mAB node type supports more functions, so the mAB node type can be used as the node type with the highest authority.

[0198] The above is only an exemplary method for determining the level of node authority. In more possible implementations, other methods can also be used to determine the level of node authority, and the embodiments of the present disclosure are not limited to this.

[0199] In addition, in more possible implementations, other methods may be used to achieve the purpose of determining an authorized node type from multiple node types. For example, the authorized node type of the fourth information may be determined to be the node type with the lowest authority.

[0200] Alternatively, the indication information includes multiple node types, and the fourth information may be determined to be multiple node types.

[0201] That is, the indication information includes multiple node types, and the multiple node types included in the indication information can all be used as authorized node types without selecting from them.

[0202] Alternatively, the indication information includes one or more node types, and it is determined that the fourth information indicates unauthorized.

[0203] Optionally, the fourth information may include authorization information corresponding to the first node type and / or authorization information corresponding to the second node type. The authorization information corresponding to the first node type may be "authorized" or "unauthorized", and the authorization information corresponding to the second node type may be "authorized" or "unauthorized".

[0204] In some embodiments, the fourth information includes authorization information corresponding to the first node type, and the authorization information corresponding to the first node type is "authorized". Alternatively, the fourth information includes authorization information corresponding to the first node type, and the authorization information corresponding to the first node type is "unauthorized". Alternatively, the fourth information includes authorization information corresponding to the second node type, and the authorization information corresponding to the second node type is "authorized". Alternatively, the fourth information includes authorization information corresponding to the second node type, and the authorization information corresponding to the second node type is "unauthorized". Alternatively, the fourth information includes authorization information corresponding to the first node type and authorization information corresponding to the second node type, and the authorization information corresponding to the first node type is "authorized", and the authorization information corresponding to the second node type is "unauthorized". Alternatively, the fourth information includes authorization information corresponding to the first node type and authorization information corresponding to the second node type, and the authorization information corresponding to the first node type is "authorized", and the authorization information corresponding to the second node type is "authorized". Alternatively, the fourth information includes authorization information corresponding to the first node type and authorization information corresponding to the second node type, and the authorization information corresponding to the first node type is "unauthorized", and the authorization information corresponding to the second node type is "authorized". Alternatively, the fourth information includes authorization information corresponding to the first node type and authorization information corresponding to the second node type, the authorization information corresponding to the first node type is "unauthorized", and the authorization information corresponding to the second node type is "unauthorized".

[0205] Step S2104: The core network device sends fourth information to the first node.

[0206] In some embodiments, after determining the fourth information, the core network device may send the determined fourth information to the first node.

[0207] Optionally, the core network device may send a Next Generation Application Protocol (NGAP) message to the first node, and the NGAP message may carry the fourth information.

[0208] In some embodiments, the NGAP message is a UE context establishment request message, a UE context modification request message, a handover request message, or a path switching request confirmation message, but is not limited thereto.

[0209] Step S2105: The first node sends the first information to the relay device based on the fourth information, or the core network device sends the fourth information to the relay device.

[0210] In some embodiments, the first node may receive fourth information sent by the core network device to perform authorization-related operations according to the fourth information.

[0211] In some embodiments, the first node may obtain the first information based on the fourth information.

[0212] For example, the first node may receive an NGAP message carrying the fourth information to obtain the first information based on the fourth information carried by the NGAP message.

[0213] In some embodiments, the fourth information may include authorization information corresponding to one or more node types.

[0214] In some embodiments, the authorization information of one or more node types in the fourth information may indicate authorization (ie, the node type is authorized), or may indicate unauthorization (ie, the node type is unauthorized).

[0215] Optionally, the fourth information includes authorization information corresponding to a node type, and the fourth information can be determined to be the first information.

[0216] That is, the fourth information includes authorization information corresponding to a node type, and the authorization information corresponding to the node type included in the fourth information can be directly used as the authorization information corresponding to the node type included in the first information, so that the first information is consistent with the fourth information.

[0217] For example, if the fourth information includes authorization information corresponding to the first node type, it can be determined that the first information also includes authorization information corresponding to the first node type. For another example, if the fourth information includes authorization information corresponding to the second node type, it can be determined that the first information also includes authorization information corresponding to the second node type.

[0218] Optionally, the fourth information indicates unauthorized access, and the fourth information may be determined to be the first information.

[0219] That is, if the fourth information indicates unauthorized, it can be directly determined that the first information also indicates unauthorized, so that the first information is consistent with the fourth information.

[0220] In some embodiments, the first information is consistent with the fourth information. When the first node sends the first information to the relay device based on the fourth information, the fourth information can be directly used as the first information, thereby forwarding the first information to the relay device to achieve an effect of sending the fourth information from the core network device to the relay device.

[0221] Optionally, the core network device may send a non-access stratum (NAS) message to the relay device, and the NAS message may carry the fourth information. The NAS message sent by the core network device may first be transmitted to the first node, and the first node may transmit the NAS message to the relay device.

[0222] In some embodiments, the relay device may receive a NAS message carrying the fourth information to achieve the purpose of receiving the fourth information, that is, to achieve the purpose of receiving the first information.

[0223] Optionally, the fourth information includes authorization information corresponding to multiple node types, and the first information can be determined to be authorization information corresponding to one of the node types.

[0224] For example, it may be determined that the first information is authorization information corresponding to the node type with the highest authority.

[0225] In some embodiments, the authority of a node type can be determined based on the number of functions supported by the node. For example, the node types include IAB node type and mAB node type. Compared with the IAB node type, the mAB node type supports more functions, so the mAB node type can be used as the node type with the highest authority.

[0226] In some embodiments, if the fourth information includes both IAB authorization information and mIAB authorization information, the first node may ignore the IAB authorization information and use the mIAB authorization information as the first information.

[0227] The above is only an exemplary method for determining the level of node authority. In more possible implementations, other methods can also be used to determine the level of node authority, and the embodiments of the present disclosure are not limited to this.

[0228] In addition, in more possible implementations, other methods can be used to achieve the purpose of determining the authorization information corresponding to a node type from the authorization information corresponding to multiple node types. For example, the first information can also be determined to be the authorization information corresponding to the node type with the lowest authority.

[0229] In some embodiments, after determining the first information, the first node may send an RRC message to the relay device, and the RRC message may carry the first information to achieve the purpose of sending the first information to the relay device.

[0230] Optionally, the relay device may receive an RRC message carrying the first information to achieve the purpose of receiving the first information.

[0231] In some embodiments, the first node may perform authorization-related operations based on the first information.

[0232] The execution of authorization-related operations includes authorization-related operations or unauthorized operations.

[0233] Taking the case where the first node type is an IAB node type and the second node type is an mIAB node type as an example, the authorization-related operations corresponding to different authorization information may be as follows:

[0234] Optionally, the authorization information of the first node type is authorized, and the authorization information of the second node type is unauthorized, that is, the IAB authorization result is authorized, and the mAB authorization result is unauthorized, then it is determined that the relay device can provide services for other terminal devices, but the relay device does not support the function of the mAB node.

[0235] Optionally, the authorization information of the first node type is unauthorized, and the authorization information of the second node type is authorized, that is, the IAB authorization result is unauthorized, and the mAB authorization result is authorized, then it is determined that the relay device can provide services for other terminal devices, and the relay device can support the functions of the mAB node.

[0236] Optionally, the authorization information of the first node type is authorization, and the authorization information of the second node type is authorization, that is, the IAB authorization result is authorization, and the mAB authorization result is also authorization, then it is determined that the relay device can provide services for other terminal devices, and the relay device can support the functions of the mAB node.

[0237] Optionally, the authorization information of the first node type is unauthorized, and the authorization information of the second node type is unauthorized, that is, the IAB authorization result is unauthorized, and the mAB authorization result is also unauthorized, then it is determined that the relay device cannot provide services for other terminal devices, and the relay device does not support the function of the mAB node.

[0238] In some embodiments, the first node may send an RRC message to the relay device, and the RRC message may carry the first information, so as to achieve the purpose of sending the first information to the relay device.

[0239] Optionally, the relay device may receive an RRC message carrying the first information to achieve the purpose of receiving the first information.

[0240] Through the above embodiment, the relay device can obtain authorization information from the first node, and can also obtain authorization information from the core network device. When obtaining authorization information from the core network device, the obtained authorization information is received from the core network device through the first node.

[0241] Step S2106: The relay device performs a connection management operation based on the first information.

[0242] In some embodiments, the connection management operation is used to configure the network connection permissions of the relay device. The network connection permissions to be configured are different when the authorization information is different, that is, the network connection capabilities to be configured are different when the authorized node types are different. For an introduction to the network connection permissions to be configured under different authorization information, please refer to the above step S2105 and will not be repeated here.

[0243] Optionally, in some embodiments, the first information indicates a node type that can be authorized or a node type that cannot be authorized.

[0244] In some embodiments, the first information indicates authorization, and authorization processing is performed, where the authorization processing is used to ensure that the relay device can provide relay services to the terminal device.

[0245] In some embodiments, the first information indicates authorization to perform a cell selection process and / or a cell reselection process.

[0246] It should be noted that the first information indicates authorization, and according to the introduction of the above embodiment, the relay node will be authorized as one of the first node type and the second node type.

[0247] Optionally, the first information is authorization information corresponding to the first node type, and the relay device can eventually reside in the first cell through cell selection processing, and / or the relay device can eventually reside in the first cell through cell reselection processing.

[0248] The first cell is a cell provided by other relay devices of the first node type. Taking the first node type as an IAB node type as an example, the first cell may be a cell provided by other IAB nodes.

[0249] Optionally, the first information is authorization information corresponding to the second node type, and the relay device can eventually reside in the second cell through cell selection processing, and / or the relay device can eventually reside in the second cell through cell reselection processing.

[0250] The second cell is a cell provided by a node of a third node type or a fourth node type, the third node type does not include the first node type, and the fourth node type does not include the second node type.

[0251] Taking the first node type as an IAB node type and the second node type as an mIAB node type as an example, the third node type is a non-IAB node type, and the fourth node type is a non-mIAB node type.

[0252] Optionally, when performing cell reselection, it can be achieved by sending a system message (such as system broadcast).

[0253] For example, the relay device may send cell reselection indication information, where the cell reselection indication information is used to instruct the relay device in a connected state to perform cell reselection.

[0254] In more possible implementations, the relay device may further send time indication information, where the time indication information is used to indicate the time point when the relay device stops working.

[0255] Optionally, the above process of sending the system message may be executed by the access network part of the relay device.

[0256] In some embodiments, the terms "component carrier (CC)", "cell", "frequency carrier", "carrier frequency" and the like can be used interchangeably.

[0257] Step S2107: The first information indicates unauthorized, and the relay device sends second information to the second node of the access network device, or the first node sends fifth information to the second node of the access network device.

[0258] In some examples, the second node may be an IAB-donor, and the second node may be a host node that serves as a relay device of an IAB-node.

[0259] In some embodiments, the second node may be a host node corresponding to the access network part of the relay device, and the second node has a logical connection with the access network part of the relay device. For example, the second node may be an F1-terminating-donor or an F1-terminating-IAB-donor.

[0260] In some embodiments, the relay device is an IAB-DU or an mIAB-DU, the first node is an IAB-MT or an IAB-donor of an mIAB-MT, and the second node is an IAB-DU or an IAB-donor of an mIAB-DU.

[0261] In some embodiments, the first node is an RRC-terminating-IAB-donor or a non-F1-terminating-IAB-donor, and the second node is an F1-terminating-IAB-donor.

[0262] The second information may be used to instruct the second node to perform unauthorized processing, and the fifth information may also be used to instruct the second node to perform unauthorized processing, where the unauthorized processing is used to ensure that the relay device cannot provide services to the terminal device.

[0263] In some embodiments, the relay device may send an F1 Application Protocol (F1AP) message to the second node, where the F1AP message includes the second information.

[0264] The F1AP message may be a base station distributed unit (gNodeB Distributed Unit, GNB-DU) configuration update request message, and the message may include the second information, but the F1AP message is not limited thereto.

[0265] In some embodiments, the first node may send an Xn Application Protocol (XnAP) message to the second node, where the XnAP message includes the fifth information.

[0266] In some instances, the first node may send a transport migration modification request (Transport Migration Modification Request) message to the second node, where the transport migration modification request message includes the fifth information.

[0267] In some embodiments, the fifth information may also be included in a Traffic To Be Released Information IE.

[0268] Step S2108: The second node performs unauthorized processing.

[0269] In some embodiments, the second node may receive the second information sent by the relay device and perform unauthorized processing according to the second information. Alternatively, the second node may receive the fifth information sent by the first node and perform unauthorized processing according to the fifth information.

[0270] Among them, the second information and the fifth information can be used to indicate at least one of the following, or in other words, the unauthorized processing to be performed by the second node may include at least one of the following: releasing the context of the access network part of the relay device; releasing the F1 connection of the relay device; prohibiting other relay devices or terminal devices from accessing the first cell, and the first cell is the cell provided by the relay device; the terminal device accessing the relay device resides in the second cell, and the second cell is different from the first cell.

[0271] Optionally, the second node may perform unauthorized processing based on the at least one indication.

[0272] Step S2109: The second node sends sixth information to the first node.

[0273] In some embodiments, when the second node performs unauthorized processing, the unauthorized processing may involve unauthorized processing that requires the cooperation of a relay device to complete.

[0274] In some embodiments, the second node may send sixth information to the first node, where the sixth information may be used to indicate the result of the operation execution of the second node for the unauthorized processing.

[0275] Optionally, the sixth information can be used to indicate at least one of the following, or in other words, the result of the operation execution for unauthorized processing can include at least one of the following: the unauthorized processing of the relay device has been completed; no terminal device has accessed the relay device; the context of the access network part of the relay device has been released; the F1 connection of the relay device has been released; other relay devices or terminal devices are prohibited from accessing the first cell, and the first cell is a cell provided by the relay device; the terminal device accessing the relay device resides in the second cell, and the second cell is different from the first cell.

[0276] Step S2110: The first node or the second node sends third information to the relay device.

[0277] The third information is used to instruct the relay device to perform unauthorized processing, and / or the third information is used to indicate the result of the operation execution of the second node for the unauthorized processing.

[0278] Optionally, the third information may include at least one of the following: releasing the context of the access network part of the relay device; releasing the F1 connection of the relay device; prohibiting other relay devices or terminal devices from accessing the first cell, where the first cell is a cell provided by the relay device; the terminal device accessing the relay device resides in the second cell, which is different from the first cell; the relay device establishes a communication connection with the core network device as a user terminal.

[0279] Step S2111: The first node sends seventh information to the core network device.

[0280] The seventh information may be used to indicate the result of executing the unauthorized process on the relay device.

[0281] For example, the seventh information may be used to indicate that all terminal devices accessing the relay device have completed switching.

[0282] In some embodiments, the core network device may receive the fifth information and send configuration information to the relay device based on the fifth information. The configuration information may be used to determine that the relay device is accessed as a common user terminal.

[0412] In an IAB scenario, the relay device may be an IAB-node (including an IAB-MT and IAB-DU), the access network device may be an IAB-donor, and the core network device may include the first network element (AMF). Referring to Figure 5A , Figure 5A is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 5A , the present disclosure relates to an information processing method, which includes the following steps.

[0413] Step S5101: IAB-MT sends instruction information to IAB-donor.

[0414] In some embodiments, the IAB-MT can only send instructions to the IAB-donor as the IAB or mobile IAB to obtain corresponding authorization information.

[0416] The optional implementation of step S5101 can refer to the optional implementation of step S2101 in Figure 2 and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0417] Step S5102: IAB-donor sends an indication message to AMF.

[0418] In some embodiments, the IAB-donor may forward the instruction information of the IAB-MT to the IAB-donor.

[0419] The optional implementation of step S5102 can refer to the optional implementation of step S2102 in Figure 2 and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0422] 3>include the miab-NodeIndication;

[0423] 2>else if connecting as an IAB-node:

[0424] 3>include the iab-NodeIndication;

[0425] Through the above signaling design, it can be ensured that when the first node type and the second node type coexist, the second node type can be given priority.

[0426] Step S5103: AMF sends the fourth message to IAB-donor.

[0427] The authorization information may include IAB authorization information and mIAB authorization information, and both the IAB authorization information and the mIAB authorization information may be authorized or unauthorized.

[0428] In some embodiments, the AMF obtains authorization information, and the AMF may send the authorization information as the fourth information.

[0429] In some embodiments, the AMF obtains two types of authorization information, and the AMF may select one type of authorization information as the fourth information to be sent.

[0436] The authorization information of mobile IAB is "unauthorized" and the authorization information of IAB is "authorized". The IAB-donor regards the terminal part of the IAB-node (denoted as UE) as an IAB-MT, that is, the IAB-node can provide services for the UE but does not support the functions of the mobile IAB-node.

[0437] The authorization information of the mobile IAB is "authorized", and the IAB authorization information is "authorized". The IAB-donor regards the UE as a mobile IAB-MT, that is, the IAB-node can provide services for the UE and support the functions of the mobile IAB-node.

[0438] The authorization information of mobile IAB is "unauthorized" and the IAB authorization information is "unauthorized". The IAB-donor regards the terminal part of the IAB-node (denoted as UE) as an ordinary user terminal, that is, the IAB-node cannot provide services for the UE and does not support the functions of the mobile IAB-node.

[0439] If the authorization information of mobile IAB is "authorized" and the IAB authorization information is "unauthorized", the IAB-donor regards the terminal part of the IAB-node (denoted as UE) as a mobile IAB-MT, that is, the IAB-node can provide services for the UE and support the functions of the mobile IAB-node.

[0445] Optionally, the IAB-donor-CU of the IAB-DU and IAB-MT are different, and the authorization status of the IAB-MT and / or mobile IAB-MT changes from "authorized" to "unauthorized". In this case, the IAB-donor-CU of the IAB-MT needs to notify the IAB-donor-CU of the IAB-DU to ensure that the IAB-node can no longer provide services to other terminal devices.

[0446] In some embodiments, Figure 5B is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure.

[0457] In some embodiments, the F1-terminating-donor sends third information to the RRC-terminating-donor, where the third information is used to indicate a result of the F1-terminating-donor performing a related operation.

[0465] In some embodiments, the AMF may send a deregistration or configuration update message to the IAB-MT based on the seventh information to ensure that the IAB-MT accesses the network as a normal UE.

[0466] Through the above embodiment, the IAB-MT of the IAB-node can be registered when there is no UE served on the IAB-node, and the authorization information of the IAB-MT can be updated without affecting other UEs.
