Fig. 1a is a schematic architecture diagram of a communication system shown in accordance with an embodiment of the present disclosure.

As shown in fig. 1a, the communication system 100 includes a terminal (terminal) 101, a first device 102, and a network device (network device) 103.

In some embodiments, the terminal 101 includes at least one of a mobile phone (mobile phone), a wearable device, an internet of things device, a communication enabled car, a smart car, a tablet (Pad), a wireless transceiver enabled computer, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in unmanned (self-driving), a wireless terminal device in teleoperation (remote medical surgery), a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation security (transportation safety), a wireless terminal device in smart city (smart city), a wireless terminal device in smart home (smart home), for example, but is not limited thereto.

In some embodiments, the first device 102 is, for example, a relay device, which may act as an IAB node, accessing the terminal to a node or device of the wireless network through the access network device 103.

In some embodiments, the first device 102 may be a mobile relay device, such as a Mobile Base Station Relay (MBSR), or a fixed relay device, such as an in-vehicle mobile base station relay.

In some examples, a mobile base station relay is a mobile base station that acts as a relay between a terminal and a network, e.g., providing an NR access link for the terminal and wireless access (using NR) to a 5G core through a hosting NG-RAN.

In some examples, the mobile base station relay may be installed on a mobile vehicle and may serve UEs located inside or outside (or entering/exiting) the vehicle.

In some examples, the mobile base station relay may be a drone relay device, i.e., the drone may act as a mobile relay node.

It may be understood that, the communication system described in the embodiments of the present disclosure is for more clearly describing the technical solutions of the embodiments of the present disclosure, and is not limited to the technical solutions provided in the embodiments of the present disclosure, and those skilled in the art may know that, with the evolution of the system architecture and the appearance of new service scenarios, the technical solutions provided in the embodiments of the present disclosure are applicable to similar technical problems.

The embodiments of the present disclosure described below may be applied to the communication system 100 shown in fig. 1a, or a part of the body, but are not limited thereto. The respective bodies shown in fig. 1a are examples, and the communication system may include all or part of the bodies in fig. 1a, or may include other bodies than fig. 1a, and the number and form of the respective bodies are arbitrary, and the connection relationship between the respective bodies is examples, and the respective bodies may not be connected or may be connected, and the connection may be arbitrary, direct connection or indirect connection, or wired connection or wireless connection.

In addition, a plurality of system combinations (e.g., LTE or a combination of LTE-a and 5G, etc.) may be applied.

Taking the 5G communication network as an example, a 5G radio access network (NG-RAN) supports IABs by radio access through IAB-nodes to a gNB capable of serving the IAB node, known as IAB-home (IAB-node). IAB-donor is a base station with IAB function.

As shown in fig. 1b, in a communication system having an IAB network structure, an IAB-donor includes one IAB-donor-CU (CU is simply referred to as a central unit) and one or more IAB-donor-DUs (CU is simply referred to as distributed units). In case of separating the gNB-CU-CP (control plane section) and the gNB-CU-UP (user plane section), the IAB-donor may include one IAB-donor-CU-CP, a plurality of IAB-donor-CU-UP and a plurality of IAB-donor-DU. An F1 interface connection is established between the IAB-donor and at least one IAB-node.

The IAB-node is connected to an upstream IAB-node or IAB-donor-DU by a subset of UE functions of the NR Uu interface, referred to as the IAB-MT functions of the IAB-node.

The IAB-node provides a wireless backhaul to downstream IAB-nodes and terminals through network functions of the NR Uu interface (referred to as IAB-DU functions of the IAB-node).

Mobile Base Station Relay (MBSR) may act as a mobile base station relay between a terminal and a network, e.g., providing an NR access link for the terminal and connecting (using NR) to the 5G core over the hosting NG-RAN radio. It is assumed that the mobile base station relay is installed on a mobile vehicle and serves UEs that may be located inside or outside the vehicle (or enter/leave the vehicle).

As shown in fig. 1c, a system architecture diagram of the MBSR access 5GC (core network) is shown. In order for the MBSR to operate as a mobile IAB node, the MBSR may receive a configuration from an OAM (Operation Administration and Maintenance, operation maintenance management) system of a designated serving PLMN (Public Land Mobile Network ). Only if the MBSR IAB-UE is authorized to operate as an MBSR in the serving PLMN will the MBSR IAB-UE establish a secure and trusted connection with the OAM server.

In some examples, for one MBSR, subscription information stored in the HPLMN (Home Public Land Mobile Network, local public land mobile network) indicates whether the MBSR is authorized to operate as an MBSR, and as the corresponding location and time period when the MBSR operates. The subscription information is stored in the UDM (Unified Data Management, unified data management function) of the HPLMN.

In some examples, the request to operate as an MBSR is indicated when an MBSR (IAB-UE) performs an initial registration with a serving PLMN. The AMF grants the MBSR according to the subscription information and provides an MBSR grant indication to the NG-RAN. The MBSR establishes a connection with the OAM system using the configuration information for MBSR operation.

In some examples, the UE needs to register with the network to obtain authorization to receive services, enable mobile tracking, and enable reachability. The terminal initiates a registration procedure using one of the following registration types:

when a new Tracking Area (TA) outside the UE registration Area initiates a mobile registration update in CM (Connection Management ) -CONNECTED and CM-IDLE states; or,

when the UE needs to update its capabilities or protocol parameters negotiated during registration (whether or not to change to a new TA); or,

when the UE needs to update its function or protocol parameters negotiated in the registration process, whether or not to update to a new TA; or,

when the preferred network behavior of the terminal changes, resulting in incompatibility with the supporting network behavior provided by the AMF providing the service; or,

when the UE intends to retrieve the LADN information; or,

upon handover to a suitable cell, using NR satellite access, indicating a plurality of TAs of the RPLMN (Registerd Public Land Mobile Network, registered public land Mobile network), all of which are outside the registration area of the UE and in CM-CONNECTED and CM-IDLE states; or,

when a multiple USIM (Universal Subscriber Identity Module, global subscriber identity card) UE requires a new 5G-GUTI (Globally Unique Temporary UE Identity ) allocation; or,

When the UE needs to indicate that it is returned from the unavailable period.

In some cases, such as duration limitation and location limitation based on MBSR subscription information, when the MBSR does not request a connected UE or the MBSR cannot provide service to the UE, the MBSR still performs MBSR operation, such as cell management by the network, which may result in network resource waste.

Fig. 2a is an interactive schematic diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in fig. 2a, an embodiment of the present disclosure relates to an information processing method for a communication system 100, the method including:

step S2101: the network device sends the second information to the first device.

In some embodiments, the first device receives second information sent by the network device.

In some embodiments, the network device may be an IAB hosting node or a core network element, which may comprise, for example, one of the following: AMF, SMF, PCF.

In some embodiments, the first device may be a relay device having a relay function, and may also operate as a terminal.

For example, the first device may be a mobile relay device, such as a Mobile Base Station Relay (MBSR), which may be a vehicle-mounted mobile base station relay, or a drone relay device, i.e. a drone may act as a mobile relay node.

In some examples, the operating modes of the first device may include a relay mode and a terminal mode, and the first device may operate as a relay node when the first device operates in the relay mode, at which time the first device may provide wireless access services to the UE. When the first device is operating in the terminal mode, the relay device may operate as a UE.

In some examples, the first device may switch modes between the relay mode and the terminal mode, e.g., the first device may switch from the relay mode to the terminal mode, or the first device may switch from the terminal mode to the relay mode.

In some embodiments, the second information may be used to indicate a time period and/or region that limits the first device to use the relay mode. Limiting a period of time during which the first device uses the relay mode, indicating a period of time during which the first device is not allowed to use (or activate) the relay mode; the area in which the first device is restricted from using the relay mode indicates an area in which the first device is not allowed to use (or activate) the relay mode.

In other embodiments, the second information may be used to indicate a period and/or region in which the first device is allowed to use (or initiate) the terminal mode.

In some examples, the second information may be determined based on subscription information of the first device.

In some examples, subscription information for the first device is stored in the UDM.

In some examples, the second information may be carried in a Non-access stratum (NAS) message, or a radio resource control (Radio Resource Control, RRC) message, sent by the network device to the first device.

In some examples, the second information may be sent by the network device to the first device during an initial registration of the first device.

Step S2102: the first device determines first indication information.

In some embodiments, the first device may determine the first indication information based on the second information.

In some embodiments, the first indication information indicates a handover event occurring at the first device.

In some embodiments, the first device determines the first indication information based on the second information. For example, the first device determines an occurring handoff event based on the second information. For example, the first device determines an occurrence of a handover event based on a period and/or an area of the first device using the relay mode indicated by the second information.

The handoff event occurring at the first device may include: the first device is currently in progress for a handover event or an impending handover event. For example, the first device may predict an impending handoff event based on its direction of movement and/or speed of movement, thereby determining the first indication information.

In some embodiments, the switching event includes at least one of a first switching event and a second switching event.

The first switching event is used for triggering the first device to switch from a relay mode to a terminal mode; the second switching event is used to trigger the first device to switch from a terminal mode to a relay mode.

In some examples, the first switching event includes one of:

the first device does not detect a terminal connection;

the first device is unable to provide services to the terminal;

As an example, the first device not detecting a terminal connection may include: the first device does not detect that the duration of the terminal connection reaches a first time length threshold.

As an example, the first switching operation may be a manual switching operation acting on the first device to switch the first device from the relay mode to the terminal mode.

In some examples, the first device is in a time period and/or region where the relay mode is restricted from being used, the first device being unable to provide services to the terminal.

The first device being in a period of time in which the relay mode is restricted from being used may include: the current time of the first device falls within a period of time in which the relay mode is restricted from being used. The first device being in an area where the use of the relay mode is restricted may include: the current location of the first device is contained within an area where the relay mode is restricted from being used.

In some examples, the first device is unable to provide service to the terminal after entering a time period and/or region in which the relay mode is restricted from use.

In some examples, the second handover event includes one of:

the first device is capable of providing services to a terminal;

As an example, the second switching operation may be a manual switching operation acting on the first device to switch the first device from the terminal mode to the relay mode.

In some examples, the first device is not in a time period and/or region where the relay mode is restricted from being used, the first device being capable of providing services to a terminal.

In some examples, the first device is capable of providing services to the terminal after the first device leaves the time period and/or region where the use of the relay mode is restricted.

Step S2103: the first device sends fifth information to the network device.

In some embodiments, the network device receives fifth information sent by the first device.

In some embodiments, the fifth information may be a mode switch indication.

In some embodiments, the fifth information may be used to request that the network device allow the first device to perform a mode switch.

In some embodiments, the fifth information may be used to indicate that the first device requests to perform a mode switch or requests a target mode to switch to, the target mode being a relay mode or a terminal mode.

In some examples, the fifth information is used to indicate that the first device requests to perform mode selection or requests a target mode of selection, the target mode being a relay mode or a terminal mode.

For example, the first device may request to select the target mode by sending fifth information to the network device when the first device is first booted.

For another example, when the duration of the first device being in the stationary state exceeds the first time threshold, the first device may request to select the target mode by sending fifth information to the network device (e.g., request to select the target mode as the relay mode, i.e., request to operate in the relay mode to provide service to the terminal).

For another example, when the duration of the first device in motion exceeds the second duration threshold, the second device may request to select the target mode by sending fifth information to the network device (e.g., request to select the target mode as the terminal mode, i.e., request to operate in the terminal mode without providing service to the terminal).

In some embodiments, the first device sends fifth information to the network device based on the first indication information.

In some embodiments, the first device sends the fifth information to the network device based on the handover event that occurred.

For example, the first device may send fifth information to the network device to request the network device to authorize the first device to perform a mode switch or request the network device to authorize the first device to switch to or operate in a target mode based on the occurred switch event.

In some embodiments, the first device sends the fifth information to the network device based on the first switching event that occurred; the fifth information is used for indicating the first device to request to execute switching from the relay mode to the terminal mode; or, the target mode for indicating the first device to request to switch to is the terminal mode.

In some examples, the switching event is a first switching event, and the fifth information further includes a first cause value indicating one of: the first device has no terminal connection; the first device is not capable of providing services to the terminal; a first switching operation for switching the first device from the relay mode to the terminal mode.

In some embodiments, the first device sends fifth information to the network device based on the second handover event occurring; the fifth information is used for indicating the first device to request to perform switching from the terminal mode to the relay mode; or, the target mode for indicating the first device to request switching to is a relay mode.

In other embodiments, the handover event is a second handover event, and the fifth information further includes a second cause value, the second cause value being used to indicate one of: the first device is capable of providing services to the terminal; and a second switching operation of switching the first device from the terminal mode to the relay mode.

In some embodiments, the fifth information may be carried in a first message sent by the first device to the network device. The first message includes at least one of: a registration request (Registration Request) message; RRC message, NAS message. For example, the RRC message may be an RRC configuration message, an RRC reconfiguration message, or the like.

In some embodiments, the network device includes an IAB host, and the fifth information is sent by the first device to the IAB host.

In other embodiments, the network device includes an AMF, and the fifth information is sent by the first device to the IAB host and sent by the IAB host to the AMF.

In some embodiments, the fifth information may be carried in the mode switch request. The mode switch request is for requesting the network device to authorize the first device to perform a mode switch indicated by the fifth information or requesting the network device to authorize the first device to switch to the target mode.

Step S2104: the network device sends third information to the first device.

In some embodiments, the first device receives third information sent by the network device.

In some embodiments, the third information is used to determine whether the first device is authorized to perform a mode switch.

In some embodiments, the first device is authorized to perform a mode switch, and the third information may be a successful mode switch indication or an authorized mode switch indication.

In some embodiments, the first device is not authorized to perform a mode switch, and the fourth information may be a failed mode switch indication or a rejected mode switch indication.

In some embodiments, the network device sends the third information to the first device after receiving the fifth information. For example, the third information is used to determine whether the first device is authorized to perform the mode switch indicated by the fifth information or to determine whether the first device is authorized to switch to the target mode indicated by the fifth information.

In some embodiments, the network device may send third information to the first device based on the pre-configuration information. For example, the preconfigured information may include a mode switching policy of the first device.

In some embodiments, the third information may be carried in the second message.

Illustratively, the second message may be a registration response message sent by the network device based on the registration request message of the first device, which is a registration accept (Registration Accept) message in case the first device is authorized to perform the mode switch; in the case where the unauthorized first device performs mode switching, the registration response message is a registration reject message.

In some embodiments, the fifth information may be carried in a registration request message and the third information is carried in a registration response message.

In some embodiments, the second message may be an RRC message sent by the network device to the first device, e.g., the RRC message may be at least one of: RRC configuration message, RRC reconfiguration message, etc.

In some embodiments, the second message may be a NAS message sent by the network device to the first device.

In some embodiments, the second message may be in a media access Control (Media Access Control, MAC) Control Element (CE) message.

In some embodiments, the network device includes an AMF, and the third information is sent by the AMF to the IAB host over the N2 interface and sent by the IAB host to the first device.

For example, the third information is carried in a registration accept message contained in the N2 message, delivered by the AMF to the IAB host, and forwarded by the IAB host to the first device, the registration accept message being transparent to the IAB host.

In some embodiments, the first device switches from relay mode to terminal mode, and the IAB host and the AMF cancel the relay operation of the first device as a relay node. The relay operation may include providing a service to the terminal.

In some embodiments, the first device switches from terminal mode to relay mode, and the IAB host and AMF initiate relay operation of the first device as a relay node.

Step S2105: the first device performs a first operation.

In some embodiments, the first operation is a mode switch operation or a mode maintenance operation.

For example, the mode switching operation is an operation in which the first device switches from the relay mode to the terminal mode, or an operation in which the first device switches from the terminal mode to the relay mode.

For example, the mode maintaining operation is an operation in which the first device remains operating in the relay mode, or an operation in which the first device remains operating in the terminal mode.

In some embodiments, the first device performs the first operation based on third information from the network device.

In some embodiments, the fifth information sent by the first device is used to indicate a mode switch requested by the first device, and the network device sends third information based on the fifth information, the third information being used to indicate whether the first device is authorized to perform the mode switch requested by the first device.

In some embodiments, the first operation is a mode switch operation when the third information indicates that the first device is authorized to perform the mode switch.

For example, the fifth information sent by the first device is used to indicate that the first device requests to switch from the relay mode to the terminal mode, and after the network device receives the fifth information, the third information is sent, where the third information is used to indicate that the first device is authorized to switch from the relay mode to the terminal mode, and the first device may perform a mode switching operation for switching from the relay mode to the terminal mode.

In some embodiments, the first operation is a mode maintenance operation when the third information indicates that the first device is not authorized to perform the mode switch.

For example, the fifth information sent by the first device indicates that the first device requests to switch from the relay mode to the terminal mode, and after receiving the fifth information, the network device sends third information, where the third information is used to indicate that the first device is not authorized to switch from the relay mode to the terminal mode, and the first device may perform a mode maintenance operation for maintaining the relay mode.

In some embodiments, the first device may remain in use for at least a portion of the relay functionality after switching to the terminal mode, e.g., the portion of the relay functionality that the first device remains in use may include: broadcasting the first device as a relay node to terminals and/or other first devices.

Step S2106: the first device sends first information to the network device.

In some embodiments, a network device receives first information sent by a first device.

In some embodiments, the first information is used to indicate that the first device is finished performing a mode switch or a target mode of the first device.

For example, the first information is used to indicate that the first device completes performing mode switching from the relay mode to the terminal mode or that the target mode of the first device is the terminal mode; alternatively, the first information is used to indicate that the first device completes performing mode switching from the terminal mode to the relay mode or that the target mode of the first device is the relay mode.

In some examples, the target mode of the first device indicated by the first information may be a target mode to which the first device has switched, or may also be a target mode that the first device is currently operating or currently selected.

In some embodiments, the first information is used to indicate a result of execution of the first operation by the first device.

For example, the first operation is an operation in which the first device switches from the relay mode to the terminal mode, and the first information indicates that the target mode of the first device is the terminal mode.

For example, the first operation is an operation in which the first device switches from the terminal mode to the relay mode, and the first information indicates that the target mode of the first device is the relay mode.

In some embodiments, the network device includes an IAB host, and the first information is sent to the IAB host by the first device.

In other embodiments, the network device includes an AMF, and the first information is sent by the first device to the IAB host and sent by the IAB host to the AMF.

Step S2107: the network device performs a second operation.

In some embodiments, the second operation may be an operation related to releasing a network resource, e.g., the network resource may include at least one of:

packet Data Unit (PDU) session;

cell resources;

radio frequency resources.

In some examples, cell resources may be used to indicate cell identity.

In some embodiments, the second operation may also be a registration area change or mobility management operation.

In some embodiments, the first device switches from the relay mode to the terminal mode, and the second operation is to release network resources associated with the relay mode of the first device.

In some embodiments, the first device switches from the relay mode to the terminal mode and the second operation is a PDU session release procedure on the core side.

Illustratively, the network device includes an AMF, the first device has a PDU session dedicated to relay operation, e.g., a data flow for OAM, and the AMF will initiate a PDU session release procedure for the network request when the first device is switching from relay mode to termination mode.

Illustratively, the PDU session release procedure may include:

AMF calls Nsmf_PDUSion_ReleaseMContext service operation to request release of PDU session. For example, the AMF sends an Nsmf_PDUSation_ReleaseMContext request to the SMF;

sending an N4 session release request (e.g., containing an N4 session ID) message to the UPF of the PDU session by the SMF, discarding all remaining packets of the PDU session by the UPF, and releasing all tunnel resources and context associated with the N4 session;

the UPF acknowledges the N4 session release request by sending an N4 session release response (e.g., containing an N4 session ID) message to the SMF.

The SMF responds to the AMF with an Nsmf_PDUSion_ReleaseMContext response. The AMF and SMF will delete all the contexts associated with the PDU session (including the PDU session ID), which are indicated as released at the UE. The SMF will also delete any events subscribed to the AMF by the SMF that are no longer needed due to PDU session release.

In other embodiments, the network device does not perform the second operation.

For example, in the case where the first device switches from the relay mode to the terminal mode, the network device does not perform a PDU session release procedure associated with the first device, and thus, signaling interactions due to the need for the first device to re-establish the PDU session procedure for subsequent switching from the terminal mode to the relay mode can be reduced.

Illustratively, the network device includes an AMF that, upon completion of the network-requested PDU session release procedure, transmits fourth information to the first device, which may include an indication of a cause of the PDU session release, such as releasing the relay running the associated PDU session.

In some embodiments, the network device is a core network device, and the core network device sends fourth information to the first device through the IAB host, and releases the PDU session between the IAB host and the first device.

In some examples, the AMF sends the fourth information to the first device via the IAB host.

For a better understanding of the embodiments of the present disclosure, the technical solution of the present disclosure is further described below by means of an exemplary embodiment.

Fig. 6 is an interactive schematic diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in fig. 6, an embodiment of the present disclosure relates to an information processing method, including:

step S6101: MBSR-UE sends registration request to AMF through IAB-Donor.

In some examples, the registration request includes a mode switch indication; the mode switch indication may be used to indicate whether the MBSR mode is switched to the UE mode or the UE mode is switched to the MBSR mode.

In some examples, the MBSR has one UE module, namely MBSR-UE, which sends a registration request containing a mode switch indication to the AMF via IAB-Donor when a mode switch event occurs.

In some examples, the registration request may contain a Cause of the mode switch (Cause Value).

In some embodiments, a handover event of the MBSR with respect to the MBSR mode and the UE mode may trigger as follows:

if the MBSR is not required to be in MBSR mode, the MBSR mode may be switched to the UE mode, for example:

MBSR does not have a UE request connection; or,

MBSR is not able to provide services to UEs, such as duration restrictions and location restrictions based on MBSR subscription information; or,

and (5) switching manually.

In some examples, the corresponding cause value for switching the MBSR mode to the UE mode may be "UE connected not automatically detected", or "manual switching", or "duration limit and/or location limit".

In some embodiments, the handover event may trigger the MBSR to switch the UE mode to the MBSR mode, for example:

manually switching; or,

the time constraint and/or the position constraint is eliminated.

In some examples, the corresponding cause value for switching the UE mode to the MBSR mode may be "manual switch" or "time duration limit and/or location limit is eliminated.

Step S6102: the AMF sends a registration accept message to the MBSR-UE.

In some embodiments, the AMF grants the handover, e.g., based on the pre-configuration, and then sends a registration accept to the MBSR-UE.

The registration acceptance includes a successful mode switch indication to the MBSR-UE.

The N2 message sent by the AMF to the IAB-Donor contains an indication of the mode switch: the UE mode is switched to the MBSR mode or the MBSR mode is switched to the UE mode.

If the MBSR is switched from MBSR mode to UE mode, IAB-Donor and AMF will cancel MBSR operation.

When the MBSR is switched from the UE mode to the MBSR mode, IAB-Donor and AMF initiate MBSR operation.

Registration acceptance is passed to the IAB-Donor by the AMF in an N2 message and then forwarded to the MBSR-UE by the IAB-Donor. Registration acceptance is transparent to IAB-Donor.

Step S6103: the AMF initiates a PDU session release procedure for the network request.

If the MBSR has a PDU session dedicated to the operation of the MBSR, e.g., traffic for OAM, and the MBSR is switching from MBSR mode to UE mode, the AMF will initiate the network requested PDU session release procedure. AMF calls Nsmf_PDUSion_ReleaseMContext service operation to request release of PDU session.

Step S6104: the SMF sends an N4 session release request message to the UPF of the PDU session.

The SMF sends an N4 session release request (N4 session ID) message to the UPF of the PDU session. The UPF will discard all remaining packets of the PDU session and release all tunnel resources and context associated with the N4 session.

Step S6105: the UPF sends an N4 session release response message to the SMF.

The UPF acknowledges the N4 session release request by sending an N4 session release response (N4 session ID) message to the SMF.

Step S6106: the SMF responds to the AMF with an Nsmf_PDUSion_ReleaseMContext response.

The AMF and SMF will delete all the contexts associated with the PDU session (N4 session ID), which are indicated as released at the UE. The SMF may also delete any events subscribed to the AMF by the SMF that are no longer needed due to the PDU session release.

Step S6107: the AMF performs a PDU session release procedure for the MBSR-UE and IAB-Donor.

After the AMF completes the network-requested PDU session release procedure, it sends a cause indication to the MBSR-UE, e.g. release the MBSR to run the associated PDU session.

The information processing method according to the embodiment of the present disclosure may include at least one of step S6201 to step S6106. For example, step S6101 may be implemented as a separate embodiment.
