[0029] This disclosure provides an information processing method, a communication device, a communication system, and a storage medium.

[0030] In a first aspect, embodiments of this disclosure propose an information processing method, executed by a first network element, comprising: sending first information to a second network element, wherein the first network element does not support processing the second information; wherein the first information is used to indicate that at least one of the following is not supported: storage and forwarding mode, and processing of the second information; the second information is used to indicate one of the following: the time when the second network element receives a NAS message, wherein the terminal corresponding to the second network element is in storage and forwarding mode; the time when the second network element sends an update location request message to the first network element, wherein the terminal is in storage and forwarding mode.

[0031] In the above embodiments, when the first network element explicitly does not support the processing of the second information, it can inform the second network element that it does not support the processing of the second information or does not support the store-and-forward mode, thereby reducing the network resource overhead and impact on access efficiency caused by the terminal repeatedly accessing the network where the first network element is located based on the store-and-forward mode.

[0032] In conjunction with some embodiments of the first aspect, in some embodiments, before sending the first information point to the second network element, the method further includes: receiving the second information sent by the second network element.

[0033] In conjunction with some embodiments of the first aspect, in some embodiments, before sending the first information to the second network element, the method further includes: receiving third information sent by the second network element, wherein the third information is used to instruct the terminal to request the use of store-and-forward mode.

[0034] In the above embodiments, timestamp information is sent to the HSS only when the terminal requests to use the store-and-forward mode. The HSS needs to determine whether the timestamp of the store-and-forward mode is supported (i.e., the processing of the second information) and inform the terminal to reduce the occurrence of abnormal terminal access.

[0035] In some embodiments, in conjunction with the first aspect, the third information is sent by the second network element after determining that both the terminal and the second network element support store-and-forward mode.

[0036] In the above embodiments, the terminal is only requested to perform subsequent operations in the store-and-forward mode if both the terminal and the second network element support the store-and-forward mode. This reduces the possibility of being unable to access the network in the store-and-forward mode because one of the terminal or the second network element does not originally support the store-and-forward mode.

[0037] In conjunction with some embodiments of the first aspect, in some embodiments, receiving the second information sent by the second network element includes: receiving an update location request message sent by the second network element, wherein the update location request message includes the second information.

[0038] In the above embodiments, the second information can be obtained in the location update request, thereby reducing the impact on terminal attachment due to the lack of support for processing the second information during the location update process.

[0039] In conjunction with some embodiments of the first aspect, in some embodiments, receiving third information sent by the second network element includes one of the following: receiving an authentication information request message sent by the second network element, the authentication information request message including the third information; receiving an update location request message sent by the second network element, the update location request message including the third information.

[0040] In the above embodiments, third information can be sent through authentication information request messages or location update request messages. On the one hand, this provides multiple ways to send third information, which can adapt to more application scenarios. On the other hand, it can save signaling overhead.

[0041] In conjunction with some embodiments of the first aspect, in some embodiments, sending the first information to the second network element includes one of the following: sending an authentication information response message to the second network element, the authentication information response message including the first information; or sending an update location response message to the second network element, the update location response message including the first information.

[0042] In the above embodiments, the first information can be sent in either the authentication information response message or the location update response message. This provides multiple ways to send the first information, which can adapt to more application scenarios, and also saves signaling overhead.

[0043] Secondly, this disclosure provides an information processing method executed by a second network element, comprising: receiving first information sent by a first network element, wherein the first network element does not support the processing of second information; wherein the second network element transmits the message at a certain time; the first information is used to indicate that at least one of the following is not supported: store-and-forward mode, and the processing of second information is supported; the second information is used to indicate one of the following: the time when the second network element receives a NAS message, wherein the terminal corresponding to the second network element is in store-and-forward mode; the time when the second network element sends an update location request message to the first network element, wherein the terminal is in store-and-forward mode.

[0044] In conjunction with some embodiments of the second aspect, in some embodiments, before receiving the first information sent by the first network element, the method further includes: sending second information to the first network element.

[0045] In conjunction with some embodiments of the second aspect, in some embodiments, before receiving the first information sent by the first network element, the method further includes: sending third information to the first network element, wherein the third information is used to instruct the terminal to request the use of store-and-forward mode.

[0046] In some embodiments, in conjunction with the second aspect, the third information is sent by the second network element after determining that both the terminal and the second network element support store-and-forward mode.

[0047] In conjunction with some embodiments of the second aspect, in some embodiments, sending second information to the first network element includes: sending an update location request message to the first network element, the update location request message including the second information.

[0048] In conjunction with some embodiments of the second aspect, in some embodiments, sending third information to the first network element includes one of the following: sending an authentication information request message to the first network element, the authentication information request message including the third information; or sending an update location request message to the first network element, the update location request message including the third information.

[0049] In conjunction with some embodiments of the second aspect, in some embodiments, receiving the first information sent by the first network element includes one of the following: receiving an authentication information response message sent by the first network element, the authentication information response message including the first information; receiving an update location request message sent by the first network element, the update location request message including the first information.

[0050] In conjunction with some embodiments of the second aspect, in some embodiments, after receiving the first information sent by the first network element, the method further includes: sending fourth information to the terminal, the fourth information being used to indicate at least one of the following: the store-and-forward mode is not allowed, and the reason for not allowing the store-and-forward mode.

[0051] In the above embodiments, the first network element can inform the terminal of the result and / or reason why the store-and-forward mode is not allowed, so that the terminal knows the reason why the store-and-forward mode is not allowed, which is beneficial to the improvement of subsequent communication, and / or so that the terminal does not access the network based on the store-and-forward mode in the future, thereby reducing the waste of resources.

[0052] Thirdly, embodiments of this disclosure propose an information processing method executed by a terminal, comprising: receiving fourth information sent by a second network element, the fourth information indicating at least one of the following: storage and forwarding mode is not allowed, and the reason for not allowing storage and forwarding mode; wherein the fourth information is sent by the second network element after receiving first information, the first information is sent by the first network element when it does not support the processing of the second information, and the first information indicates that at least one of the following is not supported: storage and forwarding mode, and the processing of the second information; the second information indicates one of the following: the time when the second network element receives the NAS message, wherein the terminal corresponding to the second network element is in storage and forwarding mode; the time when the second network element sends an update location request message to the first network element, wherein the terminal is in storage and forwarding mode.

[0053] In conjunction with some embodiments of the third aspect, in some embodiments, based on the fourth information, it is determined that the store-and-forward mode cannot be used to access the network where the first network element is located.

[0054] In the above embodiments, the waste of resources in the network where the first network element is located can be reduced when the terminal still attempts to access the network based on the store-and-forward mode after the store-and-forward mode is not allowed.

[0055] Fourthly, this disclosure provides an information processing method for a communication system, the communication system including a first network element and a second network element; the method includes: the first network element sending first information to the second network element, the first network element not supporting the processing of the second information; wherein the first information is used to indicate that at least one of the following is not supported: store-and-forward mode, and the processing of the second information; the second information is used to indicate one of the following: the time when the second network element receives a NAS message, wherein the terminal corresponding to the first network element is in store-and-forward mode; the time when the second network element sends an update location request message to the first network element, wherein the terminal is in store-and-forward mode.

As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0099] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative.

[0100] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0101] In some embodiments, FIG1B is a schematic diagram of a satellite communication architecture according to an embodiment of the present disclosure. As shown in FIG1B, the satellite establishes a communication connection with the UE through a service link, and the satellite establishes a communication connection with the ground station through a feeder link. The satellite access network is connected to both the core network and the UE; the core network includes AMF, SMF, and User Plane Function (UPF). The core network is connected to the data network.

[0102] In some embodiments, satellite access networks may be unable to provide continuous coverage services due to insufficient satellite deployment and limited coverage. This discontinuity includes interruptions in the service link between the satellite and the terminal, or the feeder link between the satellite and the ground receiving station. In such cases, to enable certain services (e.g., latency-tolerant services), the network functions on the satellite need to perform store-and-forward (S&F) functions for data and / or signaling. For example, in Figure 1B, an MME (Mobile Equipment Management) needs to be onboard to perform data store-and-forward functions.

[0103] In some embodiments, the data storage and forwarding function for satellites is implemented as shown in Figure 1C. In the storage and forwarding mode, the end-to-end interaction of signaling and / or data is divided into two processes (step A and step B), which may not run simultaneously: In step A, the UE and the satellite perform signaling and / or data interaction, at which time the connection between the satellite and the ground network is unavailable (i.e., the satellite provides a service link, but there is no available feeder link); In step B, a feeder link connection is established between the satellite and the ground network for signaling / data interaction, and satellite movement changes from establishing a service link in step A to establishing a feeder link connection in step B.

[0104] In some embodiments, satellite operations that support store-and-forward functionality are particularly suitable for latency-tolerant or non-real-time services conducted via non-geostationary orbit (NGSO) satellite access networks.

[0105] In some embodiments, in an MME-based architecture, to support UE attachment to a network with a store-and-forward mode, during UE attachment, the MME can trigger an update location process or authentication process with the HSS to obtain user subscription information or authentication vectors from the HSS. The MME can indicate a timestamp to the HSS when sending an update location request. The HSS will use this timestamp to ensure that the UE's latest update location request is not canceled. This timestamp is the time when the satellite-deployed MME receives the NAS message from the UE. After receiving this timestamp, the HSS compares it with the timestamp in a previous update location request message and determines whether to accept or reject the update location request message. If the timestamp in the update location request message is earlier than the stored timestamp, the HSS will reject the update location request message. If the HSS accepts the update location request message, the HSS will store the timestamp of the update location request message.

[0106] Optionally, timestamps are reserved for cases where some MMEs are deployed on satellites and support store-and-forward mode. If the UE performs attach via other network access methods (e.g., terrestrial access or a full core network deployed on satellite), timestamps are not required during attach.

[0107] Therefore, whether the HSS supports timestamp processing may affect the UE's ability to attach to a satellite architecture using a portion of the MME deployed.

[0108] In some embodiments, the UE can be a terminal, or the terminal can be a UE.

[0109] Figure 2 is an interactive schematic diagram illustrating an information processing method according to an embodiment of the present disclosure.

[0131] Optionally, the second information is used to indicate the time when the second network element transmits the message, wherein the terminal corresponding to the second network element is in store-and-forward mode. It is understood that if the terminal does not use store-and-forward mode, the time of message transmission does not need to be recorded (i.e., the second network element does not need to record the transmission time). However, if the terminal uses store-and-forward mode, the second network element needs to record the time of message transmission.

[0132] Optionally, the corresponding terminal to the second network element can refer to either a terminal that interacts with the second network element or a terminal that accesses the network where the second network element is located.

Here, the terminal corresponding to the second network element is in store-and-forward mode.

[0136] Optionally, the second information can be a timestamp; the timestamp is used to indicate the time when the second network element transmits the message when the terminal uses store-and-forward mode.

[0142] In some embodiments, the second information is different from the third information.

[0143] In some embodiments, the second information is the same as the third information. For example, a second network element sends second information to a first network element, the second information indicating one of the following: the time when the second network element receives a Non-Access Stratum (NAS) message, wherein the terminal corresponding to the second network element is in store-and-forward mode; the time when the second network element sends an Update Location Request message to the first network element, wherein the terminal is in store-and-forward mode; the second network element receives the second information and determines that the second information also indicates that the terminal requests to use store-and-forward mode. Here, the second information can be used to indicate the time when the second network element transmits a NAS message or an Update Location Request message, and can also be used to indicate that the terminal requests to use store-and-forward mode.

[0144] In some embodiments, “get,” “obtain,” “receive,” “transmit,” “send and / or receive” can be used interchangeably and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining through self-processing, or autonomously implementing, among other meanings.

[0145] In some embodiments, terms such as "certain", "preset", "specified", "default", "set", "indicated", "a certain", "any", and "first" can be used interchangeably. "Certain A", "preset A", "specified A", "default A", "set A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, specified A, a certain A, any A, or first A, but are not limited thereto.

[0149] Optionally, the first information is used to indicate that at least one of the following is not supported: store-and-forward mode, and the processing of the second information.

[0150] For example, the first information includes at least one of the following: a first indication information, a second indication information; the first indication information is used to indicate that store-and-forward mode is not supported; the second indication information is used to indicate that processing of the second information is not supported.

[0151] For example, the first information includes first indication information; when the first indication information is a first value, it is used to indicate that store-and-forward mode is not supported; or, when the first indication information is a second value, it is used to indicate that processing of the second information is not supported.

[0152] Optionally, the processing of not supporting the second information can be one of the following: not supporting or being unable to recognize the timestamp; being unable to recognize the second information; or being unable to recognize the time when the second network element transmits the message (at which time the terminal corresponding to the second network element is in store-and-forward mode).

For example, the processing of not supporting the second information can mean: not supporting or being unable to recognize the time when the second network element sends an update location request message to the first network element. For example, the processing of not supporting the second information can mean: not supporting or being unable to recognize the timestamp in store-and-forward mode.

[0153] Optionally, the first information is used to indicate a timestamp that does not support store-and-forward mode.

[0154] Optionally, the name of the first information is not limited, and it may be, for example, an indication that does not support the indication information, or an indication that does not support the timestamp indication information, or an indication that does not support the store-and-forward mode, etc.

[0165] In some embodiments, if the first network element does not support the processing of the second information (e.g., does not support timestamps in store-and-forward mode), and the terminal still uses store-and-forward mode, it will affect network access and / or communication. For example, if the terminal is still using store-and-forward mode to access the network where the first network element is located, it will cause abnormal access problems, making it impossible for the terminal to access the network using store-and-forward mode. Or, it will prevent the second network element from storing and / or forwarding data and / or signaling in timestamps that do not support store-and-forward mode, thus affecting network communication.

[0166] In some embodiments, the determination or judgment can be made by a value represented by 1 bit (0 or 1), or by a true or false value (boolean), or by a comparison of numerical values ​​(e.g., a comparison with a predetermined value), but is not limited thereto.

[0173] For example, the fourth information includes third indication information; when the third indication information is a first value, it is used to indicate that the store-and-forward mode is not allowed; or when the third indication information is a second value, it is used to indicate the reason why the store-and-forward mode is not allowed.

[0174] Optionally, the fourth information is sent by the second network element after receiving the first information, and the first information is sent because the first network element does not support the processing of the second information.

[0177] Optionally, based on the fourth information, the terminal determines that it cannot use store-and-forward mode to access the network where the first network element is located. That is, it cannot access the network where the first network element is deployed. Here, the network can be a PLMN.

[0178] Optionally, the terminal determines that it can use store-and-forward mode to access the network where the first network element is located. Here, the terminal needs to determine that store-and-forward mode is allowed before it can determine that it can use store-and-forward mode to access the network where the first network element is located.

When the MME-SAT detects that the feeder link from the satellite to the ground network is unavailable, it determines to temporarily reject the UE's attach request because the MME-SAT does not have the authentication vectors or subscription information required to authenticate the UE.

[0210] In step S4103, MME-SAT sends a NAS Attach Reject Message to the UE via the onboard eNB.

[0211] Optionally, if the UE indicates that it supports store-and-forward mode, the NAS attach rejection message sent by MME-SAT to the UE includes a rejection reason indicating that the NAS rejection is due to store-and-forward mode. Additionally, the NAS attach rejection message includes a wait timer to indicate that the UE should not attempt to access the same satellite access before the wait timer expires.

[0212] In step S4104A, MME-SAT sends an Authentication Data Request Message to the MME on the ground (i.e., MME-GND).

[0213] Optionally, when the feeder link becomes available, the MME-SAT sends an authentication data request message for the UE to the MME-GND (the MME deployed on the ground).

[0214] In step S4104B, the MME-GND sends an Authentication Information Request Message to the HSS.

[0215] Optionally, the MME-GND sends an authentication information request message to the HSS; if both the UE and the MME (e.g., the MME-GND) support store-and-forward mode, the authentication information request message indicates that the UE requests to use store-and-forward mode.

[0216] In step S4105, the HSS sends an Authentication Information Answer Message to the MME-GND.

[0217] Optionally, when the HSS receives an authentication information request message from the MME, if it does not support store-and-forward mode (e.g., does not support timestamps for store-and-forward mode), it will not generate an authentication vector for the UE. The HSS sends an authentication information response message to the MME-GND, indicating that the HSS does not support store-and-forward mode.

[0218] In step S4106, MME-GND sends an Authentication Data Response Message to MME-SAT.

[0219] Optionally, MME-GND sends an authentication data response message to MME-SAT, which indicates that store-and-forward mode is not supported.

[0220] In step S4107, the UE resends the NAS attach request message to the MME-SAT via the onboard eNB.

[0221] Optionally, after the waiting timer expires, the UE resends the NAS attach request message to the MME-SAT.

[0222] In step S4108, MME-SAT sends a NAS Reject Message to the UE via the onboard eNB.

[0223] Optionally, upon receiving an attach request message, since the HSS does not support store-and-forward mode, the MME-SAT sends a NAS rejection message to the UE. The NAS rejection message should include a rejection reason, indicating that the NAS rejection is due to the HSS not supporting store-and-forward mode; that is, the rejection reason is caused by the HSS not supporting timestamp processing. After receiving the rejection reason, the UE should not use store-and-forward mode to perform a new attach to the same network.

[0224] In some embodiments, the authentication information response message can be the authentication information response message in the previous embodiments; the authentication data request message can be the authentication information request message in the previous embodiments; and the authentication data response message can be the authentication information response message in the previous embodiments. The UE can be a terminal, and the terminal can be a UE.

[0225] The information processing method involved in the embodiments of this disclosure may include at least one of steps S4101 to S4108.

[0229] Example 2

[0230] Figure 4B is a flowchart illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 4B, the present disclosure relates to an information processing method, which includes:

[0231] In step S4201, the UE sends a NAS Attach Request Message to the MME (i.e., MME-SAT) on the satellite via the on-board eNB.

[0232] Optionally, the on-board eNB broadcasts information indicating that the network supports store-and-forward mode operation. The UE receives this information and, when the satellite supports store-and-forward mode and is operating in that mode, sends a NAS attach request message to the MME via the on-board eNB. The attach request message indicates the store-and-forward mode capability. Here, the on-board eNB refers to the eNB on the satellite; the on-board eNB can be replaced by an E-UTRAN or access network device.

[0233] Step S4202: The MME stores the IMSI.

[0234] Optionally, the MME-SAT is an MME on a satellite. When the MME-SAT detects that the feeder link from the satellite to the ground network is unavailable, it determines to temporarily reject the UE attach request because the MME-SAT does not have the authentication vector or user subscription information required to authenticate the UE.

[0235] In step S4203, MME-SAT sends a NAS attach rejection message to the UE via the onboard eNB.

[0236] Optionally, if the UE indicates that it supports store-and-forward mode, the NAS attach rejection message sent by MME-SAT to the UE includes a rejection reason indicating that the NAS rejection is due to the execution of store-and-forward mode. Additionally, the NAS attach rejection message includes a wait timer to indicate that the UE should not attempt to access the same satellite access before the wait timer expires.

[0237] In step S4204A, MME-SAT sends an authentication data request message to the MME on the ground (i.e., MME-GND).

[0238] Optionally, when the feeder link becomes available, the MME-SAT sends an authentication data request message for the UE to the MME-GND (the MME deployed on the ground).

[0239] In step S4204B, MME-GND sends an authentication information request message to HSS.

[0240] Optionally, the MME-GND sends an authentication information request message to the HSS to request an authentication vector for the UE.

[0241] In step S4205, the HSS sends an authentication information response message to the MME-GND.

[0242] Optionally, when the HSS receives an authentication information request message from the MME, it generates an authentication vector for the UE. The HSS sends an authentication information response message to the MME-GND to indicate the authentication vector.

[0243] Method 1:

[0244] In step S4206A, the MME-GND sends an Update Location Request Message to the HSS.

[0245] Optionally, the MME-GND sends an update location request message to the HSS to initiate an update location procedure; this update location procedure is used to request user subscription information from the HSS.

[0246] Optionally, if both the UE and the MME-GND support store-and-forward mode, the MME-GND sends an update location request to the HSS.

[0247] Optionally, the update location request message includes a timestamp, which is the time when the on-board MME receives the NAS message from the UE.

[0248] In step S4207A, the HSS sends an Update Location answer message to the MME-GND.

[0249] Optionally, when the HSS receives an update location request message including a timestamp, if the HSS does not support timestamp processing or cannot recognize the timestamp, it sends an update location response message to the MME, wherein the update location response message is used to indicate that timestamps are not supported.

[0250] Method 2:

[0251] In step S4206B, the MME-GND sends an update location request message to the HSS.

[0252] Optionally, the MME-GND sends an update location request message to the HSS to initiate an update location procedure; this update location procedure is used to request user subscription information from the HSS.

[0253] Optionally, if both the UE and the MME-GND support store-and-forward mode, the MME-GND sends an update location request to the HSS.

[0254] Optionally, the Update Location Request message includes a timestamp, which is the time when the on-board MME receives the NAS message from the UE. Alternatively, if the Update Location Request message does not include a timestamp, the HSS assumes the current time is the timestamp.

[0255] In step S4207B, the HSS sends an update location response message to the MME-GND.

[0256] Optionally, if the HSS does not support timestamps, it sends an Update Location Response message to the MME, wherein the Update Location Response message is used to indicate that the HSS does not support store-and-forward mode.

[0257] In step S4208, MME-GND sends an authentication data response message to MME-SAT.

[0258] Optionally, MME-GND sends an authentication data response message to MME-SAT, which indicates that store-and-forward mode (e.g., mode 2) or timestamp (e.g., mode 1) is not supported.

[0259] In step S4209, the UE resends the NAS attach request message to the MME-SAT via the onboard eNB.

[0260] Optionally, after the waiting timer expires, the UE re-initiates the NAS attach request message to the MME-SAT.

[0261] In step S4210, MME-SAT sends a NAS Reject Message to the UE via the onboard eNB.

[0262] Optionally, upon receiving an attach request message, if the HSS does not support store-and-forward mode (Method 2) or does not support timestamps (Method 1), the MME-SAT sends a NAS rejection message to the UE. The NAS rejection message should include a rejection reason, indicating that the NAS rejection is due to the disallowance of store-and-forward mode; that is, the rejection reason is caused by the HSS's lack of support for timestamp processing. After receiving the rejection reason, the UE should not use store-and-forward mode to perform a new attach to the same network.

[0263] In some embodiments, the authentication information response message can be the authentication information response message in the previous embodiments; the authentication data request message can be the authentication information request message in the previous embodiments; the authentication data response message can be the authentication information response message in the previous embodiments; and the location update response message can be the location update response message in the previous embodiments.
