[0213] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0214] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0215] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0216] The embodiments of the present disclosure provide an information processing method and apparatus for rationally utilizing storage and forwarding resources on a satellite.

[0217] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0218] Referring to FIG1 , FIG1 is a flow chart of an information processing method provided by an embodiment of the present disclosure. The method can be applied to a terminal. As shown in FIG1 , the method includes the following steps:

[0219] Step 101: Receive first information sent by an access network device, wherein the first information includes a store-and-forward capability identifier and / or a store-and-forward margin identifier.

[0220] For example, when the network supports onboard store-and-forward services, the network may send first information to the terminal, and the terminal may receive the first information sent by the access network device. The store-and-forward capability identifier indicates the satellite's store-and-forward capability, such as whether the satellite has store-and-forward capability. The store-and-forward margin identifier indicates the satellite's storage capacity, such as whether the satellite has a storage margin. In some embodiments, if so, the amount of storage margin on the satellite. The access network device may be, for example, a base station.

[0221] Step 102: Send a first store-and-forward request to a core network device based on the first information.

[0222] In this step, the terminal may send a registration request to the core network device based on the first information, wherein the registration request includes a store-and-forward identifier; or the terminal may send a protocol data unit (PDU) session establishment request to the core network device based on the first information, wherein the PDU session establishment request includes a store-and-forward identifier. The store-and-forward identifier may be used to indicate that the registration request or PDU session establishment request is a store-and-forward request.

[0223] In an embodiment of the present disclosure, a terminal sends a first store-and-forward request to a core network device based on first information from an access network device. Because the first information includes a store-and-forward capability identifier and / or a store-and-forward margin identifier, where the store-and-forward capability identifier indicates the satellite's store-and-forward capability and the store-and-forward margin identifier indicates the satellite's storage capacity information, the first store-and-forward request sent by the terminal can be determined based on the first information or meet the requirements of the first information, thereby enabling reasonable utilization of store-and-forward resources on the satellite.

[0224] In some embodiments, the terminal may further receive second information sent by the network device, where the second information includes one or more of the following:

[0225] The first time information is used to indicate the sending time of the second store-and-forward request for the terminal or the PDU session, or to indicate the time interval between the current time and the time when the second store-and-forward request is sent;

[0226] First indication information, used to indicate an on-board storage capacity requirement for the second store-and-forward request, such as storage capacity size, storage capacity limit, etc.;

[0227] Store-and-forward trigger events;

[0228] The second store-and-forward request includes a store-and-forward request that is temporally subsequent to the first store-and-forward request. The second store-and-forward request may also be referred to as a subsequent store-and-forward request, and includes one or more store-and-forward requests that may be sent after the first store-and-forward request. The second store-and-forward request may be sent for the terminal, i.e., based on terminal granularity, or for the PDU session, i.e., based on PDU session granularity.

[0229] The network device may include an access network device, a core network device such as a session management function (SMF), an access and mobility management function (AMF), etc. The current time may be, for example, the time when the embodiment of the present disclosure is executed, or another specified time.

[0230] The store-and-forward event includes one or more of the following:

[0231] Time trigger information, for example, the terminal sends a second store-and-forward request at a specific time, transmits on-board store-and-forward data to the satellite at a specific time, etc.;

[0232] Regional trigger information, for example, the terminal sends a second store-and-forward request when moving to certain specific areas (for example, there is no ground base station, it belongs to the satellite coverage area but the satellite in this area has no feeder link), and the terminal transmits on-board store-and-forward data to the satellite when moving to certain specific areas (for example, there is no ground base station, it belongs to the satellite coverage area but the satellite in this area has no feeder link);

[0233] Event trigger information, such as the terminal moving too fast, the terminal tending to use on-board store-and-forward, and other events.

[0234] In the embodiment of the present disclosure, the above-mentioned specific time, specific area, specific event, etc. can be notified to the terminal by the network side in a non-access stratum (NAS) message (such as a registration acceptance message, a PDU session acceptance message), or can be pre-configured in the terminal.

[0235] The second information is sent in one or more of the following ways:

[0236] Registration accept message, Radio Resource Control (RRC) reconfiguration message, User Equipment (UE) configuration update message, RRC access response.

[0237] The second store-and-forward request is sent in one or more of the following ways:

[0238] Registration message, PDU session establishment request, PDU session modification request.

[0239] After receiving the second information, the terminal may perform one or more of the following operations:

[0240] 1) Setting a first timer, wherein a timing duration of the first timer is greater than or equal to a time interval determined according to the first time information, and the first timer is used to indicate that the second store-and-forward request is prohibited from being sent before the first timer times out.

[0241] The on-satellite storage capacity requested by the second store-and-forward request satisfies the on-satellite storage capacity requirement indicated by the first indication information. For example, the on-satellite storage capacity requested by the second store-and-forward request is less than or equal to the on-satellite storage capacity indicated by the first indication information; or the sum of the on-satellite storage capacities requested by multiple second store-and-forward requests is less than or equal to the on-satellite storage capacity indicated by the first indication information.

[0242] The first timer includes a first timer for the terminal or a first timer for the PDU session. That is, before the first timer expires, the terminal no longer sends a store-and-forward request, or the terminal no longer sends a store-and-forward request for the PDU session.

[0243] 2) When the store-and-forward event is detected, sending the second store-and-forward request.

[0244] For example, when the terminal moves too fast (for example, the moving speed is greater than a preset value, which can be set as needed), the second store-and-forward request is sent.

[0245] The on-satellite storage capacity requested by the second store-and-forward request satisfies the on-satellite storage capacity requirement indicated by the first indication information. For example, the on-satellite storage capacity requested by the second store-and-forward request is less than or equal to the on-satellite storage capacity indicated by the first indication information; or the sum of the on-satellite storage capacities requested by multiple second store-and-forward requests is less than or equal to the on-satellite storage capacity indicated by the first indication information.

[0246] 3) Sending a second store-and-forward request. The on-board storage capacity requested by the second store-and-forward request satisfies the on-board storage capacity requirement indicated by the first indication information. For example, the on-board storage capacity requested by the second store-and-forward request is less than or equal to the on-board storage capacity indicated by the first indication information; or the sum of the on-board storage capacities requested by multiple second store-and-forward requests is less than or equal to the on-board storage capacity indicated by the first indication information.

[0247] Based on the above embodiment, the terminal may further receive a configuration update indication sent by the core network device, wherein the configuration update indication is used to update one or more items of information in the second information and / or the configuration update indication includes an indication to disable a store-and-forward request timer. The terminal then updates the second information according to the configuration update indication and / or updates and restarts the first timer.

[0248] Refer to Figure 2, which is a flow chart of an information processing method provided by an embodiment of the present disclosure. The method can be applied to access network equipment, such as a base station. As shown in Figure 2, the method includes the following steps:

[0249] Step 201: Send first information to a terminal, wherein the first information includes a store-and-forward capability identifier and / or a store-and-forward margin identifier;

[0250] The store-and-forward capability identifier is used to indicate the store-and-forward capability of the satellite, and the store-and-forward margin identifier is used to indicate the storage capacity information of the satellite. The store-and-forward capability identifier and / or the store-and-forward margin identifier may be determined by a core network element (AMF or SMF) based on whether the satellite has store-and-forward capability and the margin supported by the satellite for on-board store-and-forward, and notified to the access network device.

[0251] For example, when the network side supports the on-board store-and-forward service, the access network device sends the first information to the terminal. The interpretation and meaning of the first information can refer to the description of the above embodiment.

[0252] In an embodiment of the present disclosure, a terminal sends a first store-and-forward request to a core network device based on first information from an access network device. Because the first information includes a store-and-forward capability identifier and / or a store-and-forward margin identifier, where the store-and-forward capability identifier indicates the satellite's store-and-forward capability and the store-and-forward margin identifier indicates the satellite's storage capacity information, the first store-and-forward request sent by the terminal can be determined based on the first information or meet the requirements of the first information, thereby enabling reasonable utilization of store-and-forward resources on the satellite.

[0253] Based on the above embodiment, the access network device may further send second information to the terminal, where the second information includes one or more of the following:

[0254] The first time information is used to indicate the sending time of the second store-and-forward request for the terminal or PDU session, or to indicate the time interval between the current time and the time when the second store-and-forward request is sent;

[0255] first indication information, used to indicate an on-board storage capacity requirement for the second store-and-forward request;

[0256] Store-and-forward trigger events;

[0257] The second store-and-forward request includes a store-and-forward request that is temporally subsequent to the first store-and-forward request sent by the terminal.

[0258] For the explanation and meaning of the second information, reference may be made to the description of the aforementioned method embodiment.

[0259] In the embodiment of the present disclosure, the access network device may send the second information to the terminal based on one or more of the following information:

[0260] Remaining storage capacity on the satellite;

[0261] Terminal priority;

[0262] Business priorities;

[0263] The amount of on-board storage service requested by the terminal this time;

[0264] Ephemeris information, such as the next time the terminal can access a satellite and the satellite capacity of the next time the terminal can access the satellite network;

[0265] Authentication data, such as the maximum on-board store-and-forward capacity that the network allows a terminal to apply for each time or cumulatively;

[0266] Information related to the terminal data transmission rate, which includes factors that affect the terminal data transmission rate, including but not limited to latency, signal quality, and access type;

[0267] Pre-set information, which may also be referred to as information set depending on implementation, such as a request time interval.

[0268] The second information is sent in one or more of the following ways:

[0269] Registration accept message, RRC reconfiguration message, UE configuration update message, RRC access response.

[0270] Based on the above embodiment, the access network device may further receive a configuration update indication sent by the core network device and send the configuration update indication to the terminal, wherein the configuration update indication is used to update one or more items of information in the second information, and / or the configuration update indication includes a prohibition of a store-and-forward request timer indication.

[0271] See Figure 3, which is a flow chart of the information processing method provided by an embodiment of the present disclosure. The method can be applied to core network devices such as SMF, AMF, etc. As shown in Figure 3, the following steps are included:

[0272] Step 301: Receive a first store-and-forward request sent by a terminal, wherein the first store-and-forward request is sent according to first information sent by an access network device;

[0273] The storage and forwarding capability identifier is used to indicate the storage and forwarding capability of the satellite, and the storage and forwarding margin identifier is used to indicate the storage capacity information of the satellite.

[0274] In this step, the core network device may receive a registration request sent by the terminal, wherein the registration request includes a store-and-forward identifier, or receive a PDU session establishment request sent by the terminal, wherein the PDU session establishment request includes a store-and-forward identifier. The store-and-forward identifier is used to indicate that the registration request or PDU session establishment request is a store-and-forward request.

[0275] In an embodiment of the present disclosure, a terminal sends a first store-and-forward request to a core network device based on first information from an access network device. Because the first information includes a store-and-forward capability identifier and / or a store-and-forward margin identifier, where the store-and-forward capability identifier indicates the satellite's store-and-forward capability and the store-and-forward margin identifier indicates the satellite's storage capacity information, the first store-and-forward request sent by the terminal can be determined based on the first information or meet the requirements of the first information, thereby enabling reasonable utilization of store-and-forward resources on the satellite.

[0276] In the embodiment of the present disclosure, the core network device may further send second information to the terminal, where the second information includes one or more of the following:

[0277] The first time information is used to indicate the sending time of the second store-and-forward request for the terminal or PDU session, or to indicate the time interval between the current time and the time when the second store-and-forward request is sent;

[0278] first indication information, used to indicate an on-board storage capacity requirement for the second store-and-forward request;

[0279] Store-and-forward trigger events;

[0280] The second store-and-forward request includes a store-and-forward request that is located after the first store-and-forward request in time.

[0281] For the explanation and meaning of the second information, reference may be made to the description of the aforementioned method embodiment.

[0282] The store-and-forward event includes one or more of the following:

[0283] Time trigger information, for example, the terminal sends a second store-and-forward request at a specific time, transmits on-board store-and-forward data to the satellite at a specific time, etc.;

[0284] Regional trigger information, for example, the terminal sends a second store-and-forward request when moving to certain specific areas (for example, there is no ground base station, it belongs to the satellite coverage area but the satellite in this area has no feeder link), and the terminal transmits on-board store-and-forward data to the satellite when moving to certain specific areas (for example, there is no ground base station, it belongs to the satellite coverage area but the satellite in this area has no feeder link);

[0285] Event trigger information, such as the terminal moving too fast, the terminal tending to use on-board store-and-forward, and other events.

[0286] The core network device may send the second information to the terminal based on one or more of the following information:

[0287] Remaining storage capacity on the satellite;

[0288] Terminal priority;

[0289] Business priorities;

[0290] The amount of on-board storage service requested by the terminal this time;

[0291] Ephemeris information, such as the next time the terminal can access a satellite and the satellite capacity of the next time the terminal can access the satellite network;

[0292] Authentication data, such as the maximum on-board store-and-forward capacity that the network allows a terminal to apply for each time or cumulatively;

[0293] Information related to the terminal data transmission rate, which is the factors that affect the terminal data transmission rate, including but not limited to latency, signal quality, access type, etc.

[0294] Pre-set information, which may also be referred to as information set depending on implementation, such as a request time interval.

[0295] The second information is sent in one or more of the following ways:

[0296] Registration accept message, RRC reconfiguration message, UE configuration update message, RRC access response.

[0297] In an embodiment of the present disclosure, the core network device may further set a second timer, wherein the second timer is used to indicate rejection of a store-and-forward request received before the second timer expires. In other words, before the second timer expires, the access network device rejects or discards the store-and-forward request sent by the terminal, or rejects or discards the store-and-forward request sent for the PDU session.

[0298] The timing duration of the second timer is less than or equal to the timing duration of the first timer, and the timing duration of the first timer is greater than or equal to the time interval determined according to the first time information. The second timer may include a second timer for the terminal, or include a timer for the PDU session.

[0299] When a parameter update is required, the core network device may send a configuration update indication to the terminal, wherein the configuration update indication is used to update one or more items of information in the second information, and / or the configuration update indication includes a prohibition of a store-and-forward request timer indication. Simultaneously, the core network device may update and restart the second timer.

[0300] The following describes the specific implementation process of the embodiments of the present disclosure in combination with different embodiments. Among them, the access network device takes the base station as an example, and the core network equipment includes AMF, SMF, etc.

[0301] 4 and 5 are schematic diagrams of two implementation architectures of the embodiments of the present disclosure. However, the embodiments of the present disclosure are not limited to the application of these two architectures.

[0302] In Figure 4, a lightweight 5G Core Network (5GC) Access and Mobility Management Function (AMF), Session Management Function (SMF), Unified Data Management (UDM), User Plane Function (UPF) and base stations are deployed on the same satellite; in Figure 5, base stations, UPF or storage devices are deployed on low Earth Orbit (LEO) satellites, and lightweight 5GC (AMF, SMF, UDM, etc.) are deployed on high Earth Orbit (GEO) satellites.

[0303] In both architectures, the UDM stores contract information, and data is temporarily stored in the UPF. Alternatively, additional storage devices can be added and integrated with the UPF. Both architectures share the same approach for activating the store-and-forward mechanism and PDU transmission.

[0304] For terminal-initiated onboard store-and-forward services, the related art lacks a resource control mechanism for onboard storage resources through parameter negotiation with the terminal, nor a mechanism for configuring and updating store-and-forward resource parameters, such as broadcasting a store-and-forward capability identifier and the network indicating the next time the terminal should initiate the store-and-forward service. To address these issues, the present disclosure proposes an information processing method.

[0305] See Figure 6, which is a flow chart of the information processing method according to an embodiment of the present disclosure. As shown in Figure 6, the registration process at the granularity of User Equipment (UE) is described as an example. The process may include:

[0306] In step 601, a base station (Radio Access Network (RAN) in the figure) broadcasts a satellite store-and-forward capability indicator, indicating whether the satellite has onboard store-and-forward capability. The base station also broadcasts a store-and-forward margin indicator, indicating whether the satellite has a storage margin, and optionally, also includes the onboard storage margin.

[0307] Step 602: The UE establishes an RRC connection with the base station.

[0308] Step 603: The UE initiates a registration request, wherein the registration request includes a store-and-forward identifier, which is used to indicate a request for an on-board store-and-forward service.

[0309] Step 604: The network authenticates the UE's on-board storage authority and determines whether the UE can perform on-board store-and-forward services.

[0310] Step 605: If the AMF supports the UE's on-board store-and-forward request, that is, if it determines that the UE is capable of performing the store-and-forward service, the AMF determines the time when the UE can next apply for store-and-forward, the store-and-forward trigger event, the maximum request capacity for the next store-and-forward, the UE's limited capacity, and whether to send a store-and-forward trigger event to the UE based on one or more of the following factors. The UE's limited capacity refers to the maximum capacity that the UE can apply for each time or cumulatively after network authentication. The maximum request capacity for the next store-and-forward is the maximum capacity that the UE can apply for the next store-and-forward application, determined by the core network elements (such as AMF, SMF, RAN, and other network functions (NF)) based on one or more of the following factors:

[0311] a. Remaining storage space on board;

[0312] b.UE priority / service priority;

[0313] c. The amount of on-board storage service requested by the UE;

[0314] d. Ephemeris information, such as the next time the UE can access a satellite and the satellite capacity of the next time the UE accesses the satellite network;

[0315] e. Authentication data, such as the maximum on-board store-and-forward capacity that the network allows the UE to apply for each time or cumulatively;

[0316] f. Factors affecting UE data transmission rate, including but not limited to latency, signal quality, access type, etc.;

[0317] g. Pre-set information.

[0318] If the AMF determines that the UE can register but does not allow the store-and-forward service, the AMF will include a rejection flag for the store-and-forward service, the next store-and-forward request time, or the store-and-forward trigger event in the registration acceptance response. If the AMF determines that the UE is not allowed to register, it will directly return a registration failure message.

[0319] Step 606: The AMF notifies the UE of the time of the next store-and-forward request, the store-and-forward triggering event and / or capacity in the registration acceptance response.

[0320] Store-and-forward events include, but are not limited to:

[0321] a. Time-triggered information, such as the UE storing and forwarding data on the satellite at a specific time;

[0322] b. Regional trigger information, such as some UEs only transmit onboard store-and-forward data to the satellite when they move to certain areas (no ground base station, belonging to the satellite coverage area but the satellite in this area has no feeder link);

[0323] c. Event-triggered games, such as when the UE moves too fast, the UE tends to use on-board store-and-forwarding and other events.

[0324] The above-mentioned specific events, areas, and events may be notified to the UE in a NAS message (registration accept message, PDU session accept message), or may be pre-configured on the UE.

[0325] Step 607: The UE sets a first timer, namely, "UE-side store-and-forward request prohibition timer T1," based on the next store-and-forward request time. The duration of timer T1 is greater than or equal to the time interval determined based on the "next store-and-forward request time" (e.g., the time interval from the current time to the next store-and-forward request time). Before timer T1 expires, the UE will not send any more on-board store-and-forward requests; or, the UE detects a store-and-forward trigger event.

[0326] Step 608: The AMF starts a second timer corresponding to the UE, namely, the "Network-side Store-and-Forward Request Prohibit Timer T2". Before timer T2 expires, the AMF will reject the received Store-and-Forward Request and indicate that the "Network-side Store-and-Forward Request Prohibit Timer T2" has not timed out.

[0327] The timing duration of the store-and-forward request prohibition timer T1 on the UE side is ≥ the timing duration of the store-and-forward request prohibition timer T2 on the network side.

[0328] Step 609: When the UE needs to request on-board store-and-forward space again and timer T1 expires, the UE sends an initial registration or mobility registration message, carrying the store-and-forward service identifier and, optionally, the requested store-and-forward capacity. The requested store-and-forward capacity is limited by the maximum on-board store-and-forward capacity allowed by the network for the UE to request per request or cumulatively, as received during the UE registration process.

[0329] See Figure 7, which is a flow chart of the information processing method according to an embodiment of the present disclosure. As shown in Figure 7, the PDU establishment process at the service granularity is described as an example. The process may include:

[0330] Step 701: A base station (RAN in the figure) broadcasts a satellite store-and-forward capability flag, indicating whether the satellite has onboard store-and-forward capability. The base station also broadcasts a store-and-forward margin flag, indicating whether the satellite has a storage margin, and optionally, may also include the onboard storage margin.

[0331] Step 702: The UE establishes an RRC connection with the base station.

[0332] Step 703: The UE registers with the network (in this step, it can be verified whether the UE can perform on-board store-and-forward).

[0333] Step 704: The UE triggers a store-and-forward service.

[0334] Steps 705a-705b: The UE sends a PDU session establishment request to the AMF, carrying a store-and-forward flag. The AMF sends an Nsmf_PDUSession_CreateSMContext request to the SMF, carrying a store-and-forward flag.

[0335] Step 706: SMF obtains the contract data and policy rules of the PDU session.

[0336] In some embodiments, the SMF sends a Nsmf_PDUSession_CreateSMContext response to the AMF.

[0337] Step 707: If the SMF decides to allow on-board store-and-forward for the PDU session, it determines the next time the PDU session is allowed to apply for store-and-forward based on one or more of the following factors, optionally carrying the maximum requested capacity for the next store-and-forward or the limited capacity of the PDU session. The limited capacity of the PDU session refers to the maximum capacity that can be applied for each time or cumulatively by the PDU session after network authentication:

[0338] a. Remaining storage space on board;

[0339] b.UE priority / service priority;

[0340] c. The amount of on-board storage service requested by the UE;

[0341] d. Ephemeris information, such as the next time the UE can access a satellite and the satellite capacity of the next time the UE accesses the satellite network;

[0342] e. Authentication data, such as the maximum on-board store-and-forward capacity that the network allows the UE to apply for each time or cumulatively;

[0343] f. Factors affecting UE data transmission rate, including but not limited to latency, signal quality, access type, etc.;

[0344] g. Pre-set information.

[0345] Step 708: The SMF notifies the UPF to establish a session for the user plane and carries an indication of allowing on-board storage.

[0346] Step 709: SMF notifies UE that the PDU session is accepted, carrying the time when the PDU session is allowed to apply for store-and-forward next time, and optionally, carrying the maximum requested capacity of the next store-and-forward or the limited capacity of the PDU session.

[0347] In some embodiments, the SMF notifies the AMF of the time for the next store-and-forward request, the maximum requested capacity for the next store-and-forward, or the limited capacity of the PDU session. The AMF can obtain this information in the N2 PDU Request message or in the Nsmf_PDUSession_CreateSMContext Response message. In the figure, the Nsmf_PDUSession_CreateSMContext Response message can be sent to the AMF before step 707 (without carrying related information elements) or after step 707.

[0348] The process may include:

[0349] 790a, SMF sends a Namf_Communication_N1N2MessageTransfer message to AMF, carrying the time and / or limited capacity for the next application for store-and-forwarding of the PDU session; 790b, AMF sends an N2 PDU session request (N1 SM container (N1 reference point set)) to the base station, carrying the time and / or limited capacity for the next application for store-and-forwarding of the PDU session; 790c, the base station sends a PDU session accept request to the UE, carrying the time and / or limited capacity for the next application for store-and-forwarding of the PDU session.

[0350] Step 710a: The UE sets a first timer, namely, "UE-side PDU store-and-forward request prohibition timer T3," based on the next store-and-forward request time. The duration of timer T3 is greater than or equal to the time interval determined based on the received time interval for allowing the next store-and-forward request for the PDU (e.g., the time interval from the current time to the time interval for allowing the next store-and-forward request for the PDU). Before timer T3 expires, the UE will not send an on-board store-and-forward request for the PDU session with the same PDU ID.

[0351] Step 710b: The SMF starts a second timer corresponding to the UE, namely, the "Network-side PDU Store-and-Forward Request Prohibit Timer T4". Before timer T4 expires, the SMF will reject the received store-and-forward request and indicate that the "Network-side PDU Store-and-Forward Request Prohibit Timer T4" has not timed out.

[0352] In some embodiments, if the AMF stores the "network side prohibits PDU store and forward request timer T4", before timer T4 expires, the AMF will reject the received store and forward request and indicate that the "network side prohibits PDU store and forward request timer T4" has not timed out.

[0353] The timing duration of the PDU store-and-forward prohibition request timer T3 on the UE side is ≥ the timing duration of the PDU store-and-forward prohibition request timer T4 on the network side.

[0354] Step 711: When the UE needs to request on-board store-and-forward space for the PDU session again and timer T3 expires, the UE sends a PDU session modification request, carrying the store-and-forward service identifier and, optionally, the requested store-and-forward capacity. The requested store-and-forward capacity is limited by:

[0355] a. The maximum on-board store-and-forward capacity that can be applied for each or cumulatively for the PDU session type, as received during the PDU session establishment process and allowed by the network; and

[0356] b. The maximum on-board store-and-forward capacity that the UE can apply for each time or cumulatively, as received from the network during the UE registration process.

[0357] In the information shown in FIG. 6 or FIG. 7 , if an RRC reconfiguration process is performed, the information determined in step 605 or step 707 may also be notified to the UE via an RRC reconfiguration message, an RRC access response, or the like.

[0358] See Figure 8, which is a flow chart of an information processing method according to an embodiment of the present disclosure. As shown in Figure 8, an on-board store-and-forward parameter update at a UE granularity is used as an example for description. The process may include:

[0359] Step 801: When the AMF needs to update on-board store-and-forward parameters, such as the store-and-forward prohibition request timer (first timer), the maximum request capacity for the next store-and-forward, the UE's limited capacity, and the UE on-board store-and-forward triggering event, the AMF sends a UE configuration update message to the UE.

[0360] Steps 802a-802b: The UE stores and updates the parameters received from the network. If a store-and-forward prohibit request timer is received, the UE updates timer T1 and restarts T1. The AMF updates timer T2 and restarts T2.

[0361] Step 803: If the UE successfully updates the received on-board store-and-forward parameters, such as the store-and-forward prohibition request timer, the maximum request capacity for the next store-and-forward request, the UE's limited capacity, and the UE's on-board store-and-forward triggering event (if received), the UE sends a configuration update completion message to the network. Otherwise, the configuration fails. If the network receives a configuration failure, it stops timer T2 and reinitiates steps 801-803.

[0362] The above configuration parameter updating process may be performed independently or in combination with the embodiment shown in FIG. 6 .

[0363] See Figure 9, which is a flow chart of the information processing method according to an embodiment of the present disclosure. As shown in Figure 9, the on-board store-and-forward parameter update at the PDU granularity is used as an example for description. The process may include:

[0364] Step 901: When the SMF needs to update the on-board storage and forwarding parameters, such as the next storage and forwarding request time, the maximum request capacity of the next storage and forwarding, the limited capacity of the UE and other parameters, the SMF sends a PDU session modification command to the UE through the AMF, carrying the on-board storage and forwarding parameters requested to be updated.

[0365] This may include:

[0366] In step 901a, the SMF sends a Namf_Communication_N1N2MessageTransfer message to the AMF, carrying the updated on-board store-and-forward parameters. In step 901b, the AMF sends an N2 PDU session request (N1 SM container) to the base station, carrying the updated on-board store-and-forward parameters. In step 901c, an AN-specific resource modification message is sent, carrying the updated on-board store-and-forward parameters.

[0367] Step 902: The UE stores and updates the parameters received from the network. If the next store-and-forward request time is received, the UE updates timer T3 and restarts T3. The network updates timer T4 and restarts T4.

[0368] Step 903: The UE successfully updates the received on-board store-and-forward parameters, such as the PDU store-and-forward prohibition request timer T3, the maximum request capacity for the next store-and-forward, the UE's limited capacity, and other parameters (if received), and sends a PDU session response message to the SMF.

[0369] This may include:

[0370] In step 903a, the UE sends a PDU session modification response to the base station, carrying the store-and-forward parameter identifier of the terminal successfully updated; in step 903b, the base station sends an N2 NAS uplink transfer (uplink forwarding) to the AMF, carrying the store-and-forward parameter identifier of the terminal successfully updated; in step 903c, the AMF sends an Nsmf_PDUSession_UpdateSMContext request to the SMF, carrying the store-and-forward parameter identifier of the terminal successfully updated; in step 903d, the SMF sends an Nsmf_PDUSession_UpdateSMContext response to the AMF.
