[0108] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0109] The terms "first", "second", etc. in the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "or" in the present application means at least one of the connected objects. For example, "A or B" covers three scenarios, namely, Scenario 1: including A and not including B; Scenario 2: including B and not including A; Scenario 3: including both A and B. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

The following description describes the New Radio (NR) system for example purposes, and the NR term is used in most of the following descriptions, but these technologies can also be applied to systems other than the NR system, such as the 6th th Generation (6G) communication system.

[0112] Figure 1The block diagram of a wireless communication system to which embodiments of the present application can be applied is shown. The wireless communication system includes a terminal 11 and a network-side device 12. Among them, the terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer, a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR), a virtual reality (VR) device, a robot, a wearable device, a flight vehicle, a vehicle user equipment (VUE), a shipborne device, a pedestrian user equipment (PUE), a smart home (home devices with wireless communication functions, such as refrigerators, TVs, washing machines, or furniture, etc.), a game console, a personal computer (PC), a teller machine, or a self-service machine, etc., terminal-side devices. Wearable devices include: smart watches, smart bracelets, smart earphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart ankle chains, etc.), smart wristbands, smart clothing, etc. Among them, the vehicle user equipment can also be referred to as a vehicle terminal, a vehicle controller, a vehicle module, a vehicle component, a vehicle chip, or a vehicle unit, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application.

[0113] The network-side device 12 may include an access network device or a core network device. Among them, the access network device may also be referred to as a radio access network (RAN) device, a radio access network function, or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) access point (AP), or a wireless fidelity (WiFi) node, etc. Among them, the base station may be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, relay base station (RBS), serving base station (SBS), base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), home Node B (HNB), home evolved Node B, transmission reception point (TRP), on-orbit access network device, the centralized unit (CU) of the on-orbit access network device, the CU of the on-orbit access network device, or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0114] The core network device, also known as a core network network element, may include but is not limited to at least one of the following: core network node, core network function, Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Serving Gate Way (SGW), PDN Gate Way (PGW), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), Binding Support Function (BSF), Application Function (AF), etc. It should be noted that in the embodiments of this application, only the core network devices in the NR system are taken as examples for introduction, and the specific types of core network devices are not limited.

[0115] In the NTN communication system, to enable data or signaling interaction between the terminal and the terrestrial network, it is necessary to ensure that the service link (i.e., Figure 2 the link between the terminal and the satellite) and the feeder link ( Figure 2 the link between the satellite and the ground station) can maintain connections simultaneously.

[0116] In some cases, such as in the initial stage of satellite network deployment, it cannot be guaranteed that the service link and the feeder link can maintain connections simultaneously. To support data transmission (e.g., delay-tolerant service data), embodiments of the present application propose a store-and-forward communication, such as the store and forward communication (S&F) mode, as Figure 3 shown. Taking the uplink data transmission as an example, when the terminal has uplink data to send, it can first send the data to the satellite through the service link (as shown in step A in the figure), and the satellite stores the relevant data (or the network device on the satellite stores the relevant data). When the satellite moves to a position where the feeder link is available, it forwards the stored data to the ground network (as shown in step B in the figure). Similarly, when there is downlink data to be sent to the terminal, the ground network first sends the data to the satellite, and the satellite stores the relevant downlink data. When the satellite moves to a position where the service link is available, it forwards the stored data to the terminal.

[0117] Next, in conjunction with the accompanying drawings, a communication processing method, device terminal, and network-side device provided by embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0118] Please refer to Figure 4 , Figure 4 which is a flowchart of a communication processing method provided by embodiments of the present application, as Figure 4 shown, and includes the following steps:

[0119] Step 401, a first core network element obtains first information, where the first information indicates store-and-forward communication based on satellite communication.

[0120] Among them, the above-mentioned first core network element may be an MME, or other core network elements, such as an SGW or a PGW, etc. And the above-mentioned first core network element may be on the satellite or not on the satellite.

[0121] The above-mentioned obtaining of the first information may be receiving the first information sent by the terminal or the RAN device, or obtaining the first information based on pre-configured or locally configured information.

[0122] The above-mentioned store-and-forward communication based on satellite communication may be store communication or forward communication based on satellite communication, that is, storage can be performed based on the satellite, or forwarding can be performed based on the satellite; or the above-mentioned store-and-forward communication based on satellite communication may be S&F communication based on satellite communication.

[0123] The above-mentioned first information indicating store-and-forward communication based on satellite communication may indicate that the first core network element performs store-and-forward communication based on satellite communication for the terminal.

[0124] Step 402: The first core network element performs a first communication operation according to the first information.

[0125] Among them, the above first communication operation may include at least one of the following:

[0126] Session modification, session creation, specifically, it may be a communication operation related to session modification and a communication operation related to session creation.

[0127] In the embodiment of the present application, since the first information indicates store-and-forward communication based on satellite communication, the first core network element performs a first communication operation according to the first information, thereby supporting store-and-forward communication to improve the communication performance of the device, such as improving the communication performance of the terminal or the first core network element.

[0128] As an optional implementation manner, the performing the first communication operation includes:

[0129] Sending second information to the second core network element, where the second information includes at least one of the following:

[0130] First indication information, which is used to indicate that the second core network element performs data storage;

[0131] First storage time information, which is used to indicate the time for the second core network element to store data, and the first storage time information is determined according to the satellite operation cycle or the next access time of the terminal or a time window;

[0134] First return time, which is used to indicate the time or time window for the first core network element to return to access the second core network element again;

[0135] Second storage space information, which is used to indicate at least one of the following: the remaining storage space of the RAN, the storage space allocated by the RAN to the terminal, the storage space allocated by the RAN to the established PDN connection or session.

[0136] Among them, the second core network element described above can be an SGW or a PGW.

[0137] The above-mentioned first storage time information is determined according to the satellite operation cycle or the next access time or time window of the terminal. It can be determined according to the satellite operation cycle or the next access time or time window of the terminal. When the terminal accesses the network next time, the second core network element stores the corresponding data in the terminal.

[0138] The above-mentioned next access time or time window of the terminal can be the time or time window when the terminal accesses the network next time. Among them, this time can be a time period or a periodic time period, and the above-mentioned time window can be a time range or a periodic time range.

[0139] The above-mentioned first return time is used to indicate the time or time window when the first core network element returns to access the second core network element again. It can represent that the first core network element or the second core network element is on the satellite, and due to the movement of the satellite, the first core network element will return to access the second core network element again.

To avoid repeated description, this embodiment will not be elaborated here.

[0416] The following takes the first core network element as the MME, the second core network element includes the SGW or PGW, and the third core network element is the PCRF as an example, and the method provided by the embodiments of the present application will be illustrated by multiple embodiments:

[0417] Embodiment 1:

[0418] This embodiment mainly describes the creation and establishment. As Figure 9 shown, it includes the following steps:

[0419] One implementation is to establish a session during the attach process.

[0420] Step 1. The UE sends an attach request to the eNB. The attach request is carried in the RRC message, and the attach request carries second indication information. The second indication information includes the S&F indication, and the S&F indication is used to indicate that the UE performs S&F communication. The second indication information is also carried in the RRC message sent by the UE to the eNB to indicate to the eNB that the UE performs S&F communication. The eNB receives the attach request from the UE, forwards the UE's attach request to the MME, and the eNB also sends the first information (which can be Figure 4All or part of the content in the first information in the embodiment) is sent to the MME. The first information is carried in the S1-AP message sent by the eNB to the MME, and the first information includes at least one of the following:

[0421] S&F indication, used to indicate that the UE performs S&F communication, and the indication can be the S&F access communication mode.

[0422] The next access time, duration or satellite cycle of the UE, indicating the time and duration for the UE to access the network next time;

[0423] The storage space of the eNB, the remaining space, the storage space allocated by the eNB for the UE, the priority of the eNB to process data, and the priority of the eNB to store data.

[0424] One implementation is that during the attach process, a session is established through the establishment of a PDN connection.

[0425] Step 1. The UE sends a PDN Connectivity request to the eNB. The PDN Connectivity request is carried in the RRC message. The PDN Connectivity request carries second indication information, and the second indication information includes the S&F indication. The S&F indication is used to indicate that the UE performs S&F communication. The second indication information is also carried in the RRC message sent by the UE to the eNB to indicate to the eNB that the UE performs S&F communication. The eNB receives the PDN Connectivity request of the UE, forwards the PDN Connectivity request of the UE to the MME, and the eNB also sends the first information (which can be Figure 4 All or part of the content in the first information in the embodiment) is sent to the MME. The first information is carried in the S1-AP message sent by the eNB to the MME, and the first information includes at least one of the following:

[0426] a) S&F indication, used to indicate that the UE performs S&F communication, and the indication can be the S&F access communication mode.

[0427] b) The next access time and / or duration or satellite cycle of the UE, indicating the time and duration for the UE to access the network next time

[0428] c) The storage space of the eNB, the remaining space, the storage space allocated by the eNB for the UE, the priority of the eNB to process data, and the priority of the eNB to store data

[0429] Step 2. The MME receives the second indication information sent by the UE (carried in the attach request / PDN Connectivity request) or the third indication information sent by the eNB (S1-AP message). The MME determines that the UE performs S&F communication according to the second indication information or the third indication information. The MME sends a session create request to the SGW. The session create request carries the first S&F information (such as the second information received by the SGW above). The first S&F information includes at least one of the following:

[0430] a) The first information;

[0431] b) The storage space of the MME, the remaining space, the storage space allocated by the MME for the UE, the data processing priority of the MME, the data storage priority of the MME

[0432] 3. The SGW receives the session create request in step 2 sent by the MME. According to the first S&F information, it determines that the UE performs S&F communication. The SGW sends a session create request to the PGW. The session create request carries the second S&F information (such as the second information received by the PGW above). The second S&F information includes at least one of the following:

[0433] a) The first S&F information

[0434] b) The storage space of the SGW, the remaining space, the storage space allocated by the SGW for the UE, the data processing priority of the SGW, the data storage priority of the SGW

[0435] Step 4. The PGW receives the session create request in step 3 sent by the SGW. According to the second S&F information, it determines that the UE performs S&F communication. The PGW sends an IP-CAN session establishment request to the PCRF. The IP-CAN session establishment request carries the third S&F information. The third S&F information includes at least one of the following:

[0436] a) The second S&F information

[0437] b) The storage space of the PGW, the remaining space, the storage space allocated by the PGW for the UE, the data processing priority of the PGW, the data storage priority of the PGW

[0438] Step 5. The PCRF receives the IP-CAN session establishment request sent by the PGW in Step 3, and determines that the UE performs S&F communication according to the third S&F information (such as the above-mentioned fourth information), and at least one of the following:

[0439] a) Generate a PCC rule considering S&F communication according to the third S&F information. The PCC rule considering S&F communication includes authorized QoS parameters for data transmission considering the satellite cycle in the first information, such as end-to-end delay (compared with traditional (legacy) variable length)

[0440] b) Generate first S&F processing information (such as the above-mentioned first data processing policy information) for the PGW according to the third S&F information. The first S&F processing information includes at least one of the following: the data storage amount of the PDN connection, the data processing priority of the PDN connection, the data storage priority of the PDN connection (that is, which data in the PDN is preferentially stored, which can be reflected in the QoS parameters, such as priority), the data storage priority (which data has a high storage priority), the priority of the UE to store data (indicating the priority of the UE to store data). The PCRF can consider the first S&F processing information according to the storage space, remaining space of the MME, SGW, PGW, the storage space allocated for the UE, the priority of processing data, the priority of storing data, and the S&F subscription information of the UE. For example, if the storage space of the MME, SGW, PGW is large or the remaining space is large, then it is indicated in the first S&F processing information that the data storage amount configuration of the PDN connection is larger.

[0441] Step 6. The PCRF sends the PCC rule considering S&F communication and / or the first S&F processing information in Step 5 to the PGW, carried in the IP-CAN session establishment response.

[0442] Step 7. The PGW receives the PCC rule considering S&F communication or the first S&F processing information sent by the PCRF in Step 6. The PGW generates corresponding QoS rules and QoS parameters for the UE and the eNB according to the PCC rule considering S&F communication. The PGW sends second S&F processing information (such as the second data processing policy information corresponding to the PGW) to the SGW. The second S&F processing information includes:

[0443] a) The first S&F processing information received from the PCRF, or

[0444] b) The second S&F processing information generated by the PGW according to the local policy or configuration or the third S&F information. The second S&F processing information includes at least one of the following:

[0445] The data storage amount of the PDN connection, the data processing priority of the PDN connection, the data storage priority of the PDN connection (i.e., which data in the PDN is preferentially stored, which can be reflected in QoS parameters, such as priority), the data storage priority (which data has a higher storage priority), and the priority of the UE to store data (indicating the priority of the UE to store data). For example, the PGW can generate the second S&F processing information based on the storage space of the PGW, the remaining space, the storage space allocated by the PGW for the UE, the data processing priority of the PGW, and the data storage priority of the PGW in the third S&F information. For example, if the remaining space of the PGW is relatively large, then the PGW can allocate more storage space for the PDN.

[0446] Step 8. The SGW receives the second S&F processing information sent by the PGW in step 7 and sends the third S&F processing information to the MME. The third S&F processing information (such as the second data processing policy information corresponding to the SGW) includes at least one of the following:

[0447] a) The second S&F processing information, or

[0448] b) The third S&F processing information generated by the SGW according to the local policy or configuration or the second S&F information. The third S&F processing information includes at least one of the following:

[0449] The data storage amount of the PDN connection, the data processing priority of the PDN connection, the data storage priority of the PDN connection (i.e., which data in the PDN is preferentially stored, which can be reflected in QoS parameters, such as priority), the data storage priority (which data has a higher storage priority), and the priority of the UE to store data (indicating the priority of the UE to store data). For example, the SGW can generate the third S&F processing information based on the storage space of the PGW, the remaining space, the storage space allocated by the SGW for the UE, the data processing priority of the SGW, and the data storage priority of the SGW in the third S&F information. For example, if the remaining space of the SGW is relatively large, then the SGW can allocate more storage space for the PDN.

[0450] Step 9. The MME receives the third S&F processing information sent by the SGW in step 8 and sends the fourth S&F processing information (such as the above-mentioned third data processing policy information) to the UE. The fourth processing information is carried in the attach accept message or the PDN connectivity accept session management request. The fourth S&F processing information includes at least one of the following:

[0451] a) The third S&F processing information, or

[0452] b) The fourth S&F processing information generated by the MME according to the local policy or configuration or the first S&F information or the second S&F information, and the fourth S&F processing information includes at least one of the following:

[0453] The data storage amount of the PDN connection, the data processing priority of the PDN connection, the data storage priority of the PDN connection (that is, which data in the PDN is preferentially stored, which can be reflected in the QoS parameters, such as priority), the data storage priority (which data has a high storage priority), and the data storage priority of the UE (indicating the data storage priority of the UE). For example, the SGW can generate the third S&F processing information according to the storage space of the PGW, the remaining space, the storage space allocated by the SGW for the UE, the data processing priority of the SGW, and the data storage priority of the SGW in the third S&F information. For example, if the remaining space of the SGW is relatively large, then the SGW can allocate more storage space for the PDN.

[0454] Embodiment 2:

[0455] This embodiment mainly describes that due to the change of the storage space of the network device or the change of the PDN connection policy, a session modification is triggered, such as Figure 10 as shown, including the following steps:

[0456] One implementation is that the eNB performs the modification of the PDN connection due to the change of the S&F policy, such as the change of the storage space of the eNB

[0457] Step 1. The eNB carries the updated first information (which can be all or part of the first information in the Figure 4 embodiment) in the S1-AP message and sends it to the MME.

[0458] Step 2. The MME receives the first information in Step 1, and the MME sends the first S&F information (such as the above-mentioned second information received by the SGW) to the SGW, and the first information carries the above-mentioned updated first information.

[0459] Step 3. The SGW receives the first S&F information of the MME in Step 2, and sends the second S&F information (such as the above-mentioned second information received by the PGW) to the PGW, and the second information includes the first S&F information in Step 2, and jumps to the following Step 4.

[0460] One implementation is that the MME performs a modification of the PDN connection due to a change in the S&F policy, such as a change in the MME's storage space.

[0461] Step 1. The MME sends updated first S&F information to the SGW.

[0462] Step 2. The SGW receives the first S&F information of the MME in Step 2, sends second S&F information to the PGW, where the second information includes the first S&F information in Step 2, and jumps to the following Step 4.

[0463] One implementation is that the SGW performs a modification of the PDN connection due to a change in the S&F policy, such as a change in the SGW's storage space.

[0464] Step 1. The SGW sends updated second S&F information to the PCRF and jumps to Step 4.

[0465] One implementation is that the PGW performs a modification of the PDN connection due to a change in the S&F policy, such as a change in the PGW's storage space.

[0466] Step 4. The PGW sends third S&F information (such as the fourth information above) to the PCRF. If the change in the PGW is due to its own reasons, it carries the updated third S&F information. If it is triggered by the above example, the third S&F information includes the second S&F information.

[0467] Step 5. The PCRF sends first S&F processing information (such as the first data processing policy information above) to the PGW.

[0468] Step 6. The PGW sends second S&F processing information (such as the second data processing policy information corresponding to the PGW) to the SGW.

[0469] Step 7. The SGW sends third S&F processing information (such as the second data processing policy information corresponding to the SGW) to the MME.

[0470] Step 8. The MME sends fourth S&F processing information (such as the third data processing policy information above) to the UE.

[0471] Example 3:

[0472] This example mainly describes session release, as Figure 11 shown, including the following steps:

[0473] One implementation is that the eNB performs a release of the PDN connection due to a change in the S&F policy, such as a change in the eNB's storage space.

[0474] Step 1. The eNB carries the indication of insufficient S&F storage resources in the S1-AP message and sends it to the MME

[0475] Step 2. The MME receives the indication of insufficient resources in Step 1, initiates the PDN connection release process, and the MME sends a delete session request to the SGW, carrying the insufficient resources, or the insufficient eNB resources

[0476] Step 3. The SGW receives the indication of insufficient resources from the MME in Step 2, sends a delete session request to the PGW, carrying the insufficient resources, or the insufficient eNB resources, and jumps to Step 4a

[0477] One implementation is that the MME releases the PDN connection due to a change in the S&F policy, such as a change in the storage space of the MME

[0478] Step 1. The MME sends a delete session request carrying the insufficient resources, or the indication or cause value of insufficient MME resources

[0479] Step 2. The SGW receives the indication of insufficient resources from the MME in Step 1, sends it to the PGW, carrying the insufficient resources, or the insufficient MME resources, and jumps to Step 4a
