Description

Communication method, communication apparatus, communication system and storage medium

[0001] The present application claims priority from the Chinese patent application No. 202410854799.4 filed on June 27, 2024, and entitled "A communication method, a communication apparatus, a communication system and a storage medium", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the field of communication technology, in particular to a communication method, a communication apparatus, a communication system and a storage medium. BACKGROUND

[0003] At present, a development focus in the field of communication systems is global mobile communication, and an important component of mobile communication is satellite communication. In some important fields, such as space communication, aviation communication, maritime communication, etc., satellites play an irreplaceable role. Satellite communication has the characteristics of long communication distance, large coverage area, flexible networking, etc., and can provide services for both fixed terminals and various mobile terminals.

[0004] The 3rd generation partnership project (3GPP) standard proposes an internet of thing (IoT) communication method based on a store-and-forward mechanism, i.e., a satellite stores communication data sent by a terminal locally until the satellite establishes a communication connection with a destination, and then sends the communication data to the destination. In order to support store-and-forward based on a control plane, the standard currently proposes a scheme of deploying a mobile management entity (MME) with simplified functions on a satellite. The MME located on the satellite is named MME-NT and has part of the functions of a conventional MME. The MME-NT is mainly used to maintain an S1 interface between a radio access network (RAN) and the MME-NT, maintain an association identifier of a UE in the MME, and encode and decode non-access stratum (NAS) messages sent by a user equipment (UE) to a ground MME.

[0005] The functions of the MME-NT are relatively simple, and it is mainly responsible for maintaining the smoothness of the control plane and then transmitting small packets of user data. However, other control plane processing of the UE still needs to return to the ground core network element, and therefore the problem of deploying core network functions on a satellite cannot be solved.

[0096] The embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art can know that, with the development of technology and the emergence of new scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0097] The terms "first", "second", and the like in the specification of the present application, claims, and drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, and this is only a way of distinguishing the objects with the same attributes in the description of the embodiments of the present application. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, so that the processes, methods, systems, products, or equipment containing a series of units do not have to be limited to those units, but can include other units not clearly listed or inherent to these processes, methods, products, or equipment.

[0098] First, some technical terms involved in the embodiments of the present application are introduced.

[0099] 1) mobile management entity (MME);

[0100] MME is one of the core network elements in the 4th generation mobile communication technology (4G) core network, responsible for mobility management and control, including user authentication, paging, location update and handover, etc. In the hardware architecture of the 4G core network, MME usually exists as a control plane element, cooperating with the serving gateway (SGW) and packet data network gateway (PGW) responsible for user plane processing to provide comprehensive mobile communication services for users.

[0101] 2) access and mobility management function (AMF) network element;

[0102] The AMF network element is responsible for processing the registration request of the user equipment (UE), managing the connection between the UE and the core network, ensuring the reachability of the UE, and managing the mobility of the UE, such as handling the handover between the base stations connected by the UE. When the user accesses, the AMF network element provides authentication and authorization functions to ensure that only legitimate users can access network services. In addition, the AMF network element is also responsible for other access and mobility management functions of the UE, which will not be described here.

[0103] 3) a session management function (SMF) network element;

[0104] The SMF network element is responsible for the establishment, modification and release of a session, including maintaining a tunnel between a user plane function (UPF) and an access network (AN) node. At the same time, the SMF network element has the ability to allocate and manage an internet protocol (IP) address for a UE, including an optional authorization function. In addition, the SMF network element is also responsible for other session management functions related to the UE, which will not be described here.

[0105] Referring to FIG. 1, the ground network architecture on which the communication method in the embodiment of the present application is based is briefly described as follows:

[0106] FIG. 1 is a possible, non-limiting system diagram. As shown in FIG. 1, the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 1, collectively referred to as 120). The RAN 100 can also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 1), etc. The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be different physical devices, or they can be the same physical device integrated with the core network logic function and the radio access network logic function.

[0107] The RAN 100 can be a 3rd generation partnership project (3GPP) related cellular system, such as a 4G, 5G mobile communication system, or a future-oriented evolution system. The RAN 100 can also be an open-radio access network (ORAN), a cloud-radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 100 can also be a communication system that combines two or more of the above systems.

[0108] The RAN node 110, which can also be referred to as a network device or an access network device, a RAN entity or an access node, etc., forms part of the communication system and can be configured to facilitate wireless access by the terminals. The RAN nodes 110 in the communication system 10 can be of the same type or can be of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative, e.g., the network element 120i in Figure 1 can be a helicopter or a drone, which can be configured to move as a mobile base station, to the terminal 120j accessing the RAN 100 via the network element 120i, the network element 120i is a base station; but to the base station 110a, the network element 120i is a terminal. The RAN nodes 110 and the terminals 120 are sometimes referred to as communication apparatuses, e.g., the network elements 110a and 110b in Figure 1 can be understood as communication apparatuses with base station functionalities, and the network elements 120a-120j can be understood as communication apparatuses with terminal functionalities.

[0109] In a possible scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a WiFi system, etc. The RAN node can be a macro base station (e.g., 110a in Figure 1), a micro base station or an indoor station (e.g., 110b in Figure 1), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in vehicle to everything (V2X) technology can be a road side unit (RSU). All or part of the functions of the RAN node in this application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (e.g., a cloud platform). The RAN node can also be provided with a communication module, circuit or chip for performing corresponding communication functions, and program instructions for performing corresponding communication functions.

The RU can be included in a radio frequency device or a radio frequency unit, for example, included in a remote radio unit (RRU), an active antenna processing module (AAU), or a remote radio head (RRH).

[0111] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the CU, the CU-CP, the CU-UP, the DU and the RU are taken as examples for description in this application. Any one of the CU (or the CU-CP, the CU-UP), the DU and the RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

For example: the terminal device can send uplink data to the network device through the physical uplink shared channel (PUSCH) in the UL direction; the network device can send downlink data to the terminal device through the physical downlink shared channel (PDSCH) in the DL direction. The terminal device can be a terminal device supporting new radio, which can access the network device through the air interface and initiate calls, Internet access, and other services. Illustratively, the network device can be a RAN device carried on a flight platform. When the RAN device is carried on the flight platform, the RAN device moves synchronously with the flight platform, and the RAN device and the flight platform can be regarded as a whole. At this time, the flight platform can be regarded as the RAN device, or the flight platform can be described as working in a regenerative mode, that is, the flight platform has the function of the RAN device. In addition, the communication link between the flight platform and the terminal device can be referred to as a service link. When multiple flight platforms are included in the communication system, the flight platforms can communicate with each other through an Xn interface.

The network architecture and service scenarios described in the present application are for more clearly illustrating the technical solutions of the present application, and do not constitute a limitation on the technical solutions provided by the present application. Those skilled in the art can know that, with the evolution of network architecture and the appearance of new service scenarios, the technical solutions provided by the present application are also applicable to similar technical problems.

[0126] FIG. 3 shows an application scenario to which the embodiments of the present application are applicable. The first node 301 and the second node 302 provide services for the same ground area. Taking the example that both the first node 301 and the second node 302 are satellites, the first node 301 and the second node 302 are located in the same satellite orbit. The terminal device 303 is located in the ground area served by the first node 301 and the second node 302, and communicates with the anchor core network device 304 through the access network device deployed on the satellite. As shown in FIG. 3, the second node 302 leaves the ground area, and the first node 301 provides services for the ground area. The first node 301 and the second node 302 communicate with the terminal device 303 through New Radio, the first node 301 and the second node 302 communicate with each other through an Xn interface, and the first node 301 and the second node 302 communicate with the anchor core network device 304 through an NG interface. The anchor core network device 304 can be a core network device located on the ground or a core network device deployed on a satellite, which is not limited here.

[0127] Currently, the standard proposes a scheme of deploying a simplified-function MME on a satellite. The MME located on the satellite is named MME-NT, which has part of the functions of a regular MME. The MME-NT is mainly used for maintaining the S1 interface between the RAN and the MME-NT, maintaining the association identifier of the UE in the MME, and encoding and decoding the non-access stratum (NAS) messages sent by the UE to the ground MME.

[0128] The functions of the MME-NT are relatively simple, and it is mainly responsible for maintaining the smoothness of the control plane and then transmitting small packets of user data. However, other control plane processing of the UE still needs to return to the ground core network element, and therefore the problem of deploying core network functions on the satellite cannot be solved.

[0129] Based on this, the embodiments of the present application provide a method. Hereinafter, the first node is taken as a first satellite, and the second node is taken as a second satellite as an example for description. It should be noted that the embodiments of the present application are only examples, and in actual application, the first node and the second node can be other flight platforms, which are not limited here.

[0130] Referring to FIG. 4, a communication method in the embodiments of the present application includes:

[0131] 401、The anchor core network device sends configuration parameters to the first satellite, and correspondingly, the first satellite receives the configuration parameters from the anchor core network device;

[0132] The first satellite receives at least one set of configuration parameters from the anchor core network device, which are used by the function agent of the first satellite to provide services for at least one terminal device, wherein the configuration parameters are pre-configured by the anchor core network device according to the request message.

[0133] Specifically, the function agent includes one or more of a control plane agent, a user plane agent, a computing plane agent, or a data plane agent, and the function agent is co-located with the access network device, i.e., the function agent and the access network device are both deployed on the satellite. The function agent can also include an agent of other core network functions or on-board functions, which are not limited here.

[0134] The configuration parameters created by the anchor core network for the control plane agent are control plane parameters, wherein the control plane parameters include transmission parameters of control plane messages, and configuration parameters for control procedures, which are not limited here. The control plane parameters are used by the control plane agent to process control plane messages from terminal devices, including session management, authentication management, and mobility management messages. The control plane parameters are created by anchor core network elements including AMF.

[0135] The configuration parameters created by the anchor core network for the user plane agent are user plane parameters, wherein the user plane parameters include one or more of an IP address, an identification of a data transmission tunnel, a classification policy for user data, a forwarding policy for user data, or a priority of user data, which are not limited here. The user plane parameters are used by the control plane agent to process user plane messages from terminal devices. The user plane parameters are created by anchor core network elements including SMF.

[0136] The configuration parameters created by the anchor core network for the computing plane agent are computing parameters, wherein the computing parameters include one or more of a preset algorithm, pre-authorized computing resources (such as the number of processors or the size of memory, etc.), and transmission resource configuration for parameter interaction in the computing process, which are not limited here. The preset algorithm includes algorithms available to the computing plane agent. The computing parameters are used by the computing plane agent to provide on-board computing services for terminal devices.

[0137] The configuration parameters created by the anchor core network for the data plane agent are data parameters, wherein the data parameters include one or more of sensor configuration, transmission resources for cached data, storage resources for cached data, formats of collected data, or preprocessing operations on collected data, which are not limited here. The data parameters are used by the data plane agent to provide on-board data services for terminal devices.

[0138] In a possible implementation, the first satellite is deployed with a storage unit for caching at least one set of configuration parameters for the first satellite. The functional agent can load the configuration parameters from the storage unit for execution.

[0139] In another possible implementation, the configuration parameters are cached on the functional agent, constituting a service resource pool. The functional agent loads the configuration parameters through the service resource pool.

[0140] In the embodiments of the present application, based on the configuration parameters pre-configured by the anchor core network, the first satellite can provide partial core network services for the terminal device, improving the network performance in some scenarios.

[0141] It should be noted that the configuration parameters created by the anchor core network device for the first satellite can be static, i.e., fixed, or dynamic, i.e., the configuration parameters are dynamically updated as the position of the satellite changes. For example, the control plane parameters configured by the anchor core network device for the first satellite can be instructed by the ground core network device to update the first satellite, or the first satellite can be triggered based on an event to update the control plane parameters, which is not limited here.

[0142] It should be understood that the first satellite provides services for at least one terminal device in the ground area, and a set of configuration parameters can provide services for one terminal device or multiple terminal devices. The configuration parameters can be shared by multiple terminal devices, thereby avoiding the anchor core network device from configuring repeated parameters for multiple terminal devices in the same cell and reducing resource overhead. That is, the pre-configured configuration parameters can be node-level, i.e., shared by multiple terminal devices, or user-level, i.e., a set of configuration parameters corresponds to one terminal device.

[0143] 402、The first terminal device sends a first message to the first satellite, and correspondingly, the first satellite receives the first message from the first terminal device;

[0144] In a possible implementation, the first message sent by the first terminal device to the first satellite is a control plane message. For example, the first terminal device needs to build a user plane channel with the core network device, and sends a control plane message to the first satellite. As shown in FIG. 5, the RAN device on the first satellite receives the control plane message from the first satellite, and the RAN device forwards the control plane message to the control plane agent. Wherein, the RAN device and the first terminal device communicate through new radio, and the RAN device and the control plane agent communicate through N2 interface.

[0145] In another possible implementation, the first terminal device sends a first message to the first satellite, where the first message is used to request invoking the on-board computing service of the first satellite, and the RAN device on the first satellite forwards the first message to the computing plane agent, and the computing plane agent provides services for the first terminal device.

[0146] 403、The first satellite determines the first parameter according to the at least one set of configuration parameters and the first message.

[0147] The first satellite determines the first parameter according to the at least one set of configuration parameters configured by the anchor core network device and the first message from the first terminal device, and the first parameter is used by the first satellite to provide services for the first terminal device.

[0148] Specifically, in a possible implementation, the first satellite selects a set of configuration parameters, i.e., the first parameter, from the at least one set of configuration parameters according to the first message of the first terminal device. The first parameter is determined by a decision maker in the function agent, where the decision maker includes a matching rule and a processing rule. The matching rule includes one or more of the following: an identifier of a terminal device, a task identifier, a target network element identifier, a time delay requirement identifier, time information, and network element location information, which are not limited here. The processing rule includes one or more of the following: a candidate parameter identifier, a calling priority of a candidate parameter, and an adjustment mode of a candidate parameter, which are not limited here. The adjustment mode of the candidate parameter can be a variation range of the candidate parameter, and a specific value is determined by the function agent. The first satellite can select a set of configuration parameters as the first parameter from the at least one set of configuration parameters according to the matching rule and the processing rule.

[0149] In another possible implementation, the first satellite adjusts a set of configuration parameters in the at least one set of configuration parameters according to the first message of the first terminal device to obtain the first parameter, which is not limited here.

[0150] In the embodiments of the present application, the first satellite determines the first parameter according to the pre-configured configuration parameters and the first message of the first terminal device, so that the first satellite can allocate configuration parameters according to the requirements of the terminal device, and the network performance of the terminal device is improved.

[0151] In a possible implementation, the first satellite activates the first parameter to serve the first terminal device. For example, the first satellite can determine a first control plane parameter from the at least one set of control plane parameters according to the control plane message of the first terminal device, the first satellite generates a first user plane parameter according to the first control plane parameter, and calls the first user plane parameter to provide data transmission services for the first terminal device. For another example, the first satellite can determine a first user plane parameter from the at least one set of user plane parameters according to the control plane message of the first terminal device, and directly activate the first user plane parameter to provide data transmission services for the first terminal device.

[0152] It should be noted that in a possible implementation, the configuration parameters created by the anchor core network device or the first parameters determined by the first satellite can meet part of the service requirements of the first terminal device. Specifically, the first terminal device provides services for part of the services of the first terminal device according to the first parameters, and the remaining services of the first terminal device are provided by another node (such as the anchor core network device or the second satellite).

[0153] Optionally, the embodiment shown in FIG. 4 further includes step 400a. Step 400a can be performed before step 401.

[0154] 400a, the first satellite sends a first request message to the anchor core network device, and correspondingly, the anchor core network device receives the first request message from the first satellite;

[0155] Before the first satellite enters the ground service area where the first terminal device is located, the first satellite can send a first request message to the anchor core network device, and the first request message is used to request the anchor core network device to create at least one set of configuration parameters for the first satellite.

[0156] Specifically, after receiving the first request message, the anchor core network device can create at least one set of configuration parameters according to a plurality of terminal devices in the ground service area where the first terminal device is located and service statistics of the plurality of terminal devices, or create at least one set of configuration parameters according to a resource description or capability description of the functional agent on the first satellite, which is not limited here.

[0157] It should be noted that the preconfigured parameters of the anchor core network device include on-satellite parameters and ground parameters, wherein the on-satellite parameters are the configuration parameters shown in the foregoing embodiments and are called by the functional agent on the satellite. The ground parameters can be used for message processing shunted to the ground or for message processing together with the on-satellite parameters under the instruction of the on-board functional agent, which is not limited here.

[0158] It should be understood that if the first satellite requests the anchor core network device to create configuration parameters before entering the ground service area where the first terminal device is located, after the first terminal device and the first satellite establish a connection, the first message shown in step 402 can be a core network service request of the first terminal device, and the first satellite can determine the first parameters according to the core network service request of the first terminal device.

[0159] Optionally, the embodiment shown in FIG. 4 further includes step 400b. Step 400b can be performed before step 401.

[0160] 400b, the first terminal device sends a second request message to the anchor core network device, and correspondingly, the anchor core network device receives the second request message from the first terminal device;

[0161] In a possible implementation, when the first terminal device makes a core network service request to the anchor core network device for the first time, the first terminal device can send a second request message to the anchor core network device, where the second request message includes indication information used to request the anchor core network device to create configuration parameters for the first satellite.

[0162] For example, the first terminal device sends a registration request to the anchor core network device, where the registration request includes an indication bit. If the indication bit is 0, it indicates that the registration request is used for the first terminal device to register to the core network. If the indication bit is 1, it indicates that the registration request is used to instruct the anchor core network device to create configuration parameters for the first satellite, instead of being used to invoke a core network service.

[0163] It should be understood that the above description is only an example, and the indication information can be carried in other core network service requests, which are not limited herein. The indication information can have other forms, which are not limited herein.

[0164] It should be noted that the preconfigured configuration parameters requested by the first terminal device can be used to provide services for the first terminal device and the second terminal device, that is, the preconfigured configuration parameters requested by the first terminal device can be shared by the first terminal device and the second terminal device. Correspondingly, the configuration parameters used to provide services for the first terminal device can also be preconfigured by the anchor core network device according to the second request message sent by the second terminal device, which is not limited herein.

[0165] Steps 400a and 400b in the embodiments of the present application can only perform one of the steps, that is, only step 400a or only step 400b, which is not limited herein.

[0166] Optionally, the embodiment shown in FIG. 4 further includes step 404. Step 404 can be performed after step 403.

[0167] 404. The first satellite sends the first parameters to the first terminal device, and correspondingly, the first terminal device receives the first parameters from the first satellite.

[0168] After the first satellite determines the first parameters, the first satellite can send the first parameters to the first terminal device, and the first terminal device determines whether to use the first parameters.

[0169] For example, the first satellite selects the first user plane parameters from at least one set of control plane parameters according to the control plane message of the first terminal device, and the first satellite sends the first user plane parameters to the first terminal device, and the first terminal device determines whether to use the first user plane parameters.

[0170] For another example, the first satellite selects a set of user plane parameters from the at least one set of control plane parameters according to the control plane message of the first terminal device, and adjusts the first user plane parameters according to the set of user plane parameters, and sends the first user plane parameters to the first terminal device, and the first terminal device determines whether to adopt the first user plane parameters.

[0171] Optionally, the embodiment shown in FIG. 4 further includes step 405. Step 405 can be executed after step 404.

[0172] 405. The first terminal device sends a feedback message to the first satellite, and correspondingly, the first satellite receives the feedback message from the first terminal device.

[0173] In a possible implementation, if the first terminal device decides to adopt the first parameters determined by the first satellite, the first terminal device sends a feedback message to the first satellite.

[0174] In another possible implementation, the first terminal device sends a feedback message to the first satellite, and the feedback message carries information indicating whether the first terminal device adopts the first parameters determined by the first satellite.

[0175] Optionally, the embodiment shown in FIG. 4 further includes step 406. Step 406 can be executed after step 405.

[0176] 406. The first satellite activates the first parameters in response to the feedback message.

[0177] If the first terminal device receives the first parameters, the first satellite activates the first parameters according to the feedback message.

[0178] For example, if the first terminal device decides to adopt the first control plane parameters determined by the first satellite, the first terminal device sends a feedback message to the first satellite, and the first satellite activates the first control plane parameters according to the feedback message. Then, the first satellite generates first user plane parameters according to the activated first control plane parameters, and uses the first user plane parameters to provide data transmission services for the first terminal device.

[0179] For another example, if the first terminal device decides to adopt the first user plane parameters determined by the first satellite, the first terminal device sends a feedback message to the first satellite, the first satellite activates the first user plane parameters according to the feedback message, and uses the first user plane parameters to provide data transmission services for the first terminal device. Details are not limited herein.

[0180] Optionally, the embodiment shown in FIG. 4 further includes step 407. Step 407 can be executed after step 401, or can be executed before step 401. Details are not limited herein.

[0181] 407、The anchor core network device sends the offloading rule to the first satellite, and correspondingly, the first satellite receives the offloading rule from the anchor core network device;

[0182] The control plane agent co-located with the RAN device on the first satellite undertakes the task of offloading the control plane message, wherein the offloading rule in the control plane agent is created by the anchor core network device and uploaded to the first satellite, and the offloading rule is used by the control plane agent to determine whether to offload the service request of the terminal device to another communication device. In one possible implementation, if the first satellite cannot provide services for the terminal device, the first satellite can offload the service request of the terminal device to another communication device according to the offloading rule. Wherein, the first satellite cannot provide services for the first terminal device can be that the configuration parameters created by the anchor core network device are not configured on the first satellite, or the configuration parameters on the first satellite do not meet the configuration requirements of the terminal device. In another possible implementation, if the first satellite can meet part of the service request of the terminal device, the first satellite can offload the remaining service request of the terminal device to another communication device according to the offloading rule, which is not limited here.

[0183] Specifically, the offloading rule can include multiple matching fields, such as one or more of the following: delay requirement of control plane message processing, list of control plane messages, identifier of terminal device, geographical location of terminal device, and destination network element address of control plane message, which is not limited here. Wherein, the list of control plane messages includes different control plane message types, such as session establishment or modification, authentication, handover request, etc.

[0184] In one possible implementation, the first satellite can determine whether to offload the message of the terminal device according to the offloading rule based on the start condition of the offloading rule. Wherein, the start condition of the offloading rule can be determined based on one or more of the following: description applied by the terminal device in registration, subscription information of the terminal device, location information of the terminal device, location information of the first satellite, or connectivity of the first satellite and the ground backhaul link.

[0185] For example, if the subscription information of the first terminal device indicates that the first terminal device does not start the offloading rule, the first satellite does not need to determine according to the offloading rule when receiving the service request of the first terminal device, and can directly offload the service request of the first terminal device to another communication device.

[0186] It should be understood that the offloading rule is used by the first satellite to determine whether to offload a service request from the first terminal device to another node. In one possible implementation, if the service request satisfies the offloading rule, the first satellite offloads the service request to another node, and if not, the first satellite processes the service request locally. In another possible implementation, if the service request satisfies a first condition of the offloading rule, the first satellite offloads the service request to another node, and if the service request satisfies a second condition of the offloading rule, the first satellite processes the service request locally, which is not limited here.

[0187] It should be noted that if all the control plane parameters or user plane parameters pre-configured on the first satellite have been allocated, the offloading rule is closed, that is, the first satellite offloads all service requests from the terminal device to another communication device.

[0188] In one possible implementation, the first satellite can provide services for part of the services of the first terminal device, and then offload other part of the services to another node for processing. That is, the first satellite can jointly provide services for the first terminal device with another node, such as an anchor core network device or a second satellite.

[0189] Optionally, the embodiment shown in FIG. 4 further includes step 408. Step 408 can be performed after step 407.

[0190] 408. The first terminal device sends a second message to the first satellite, and correspondingly, the first satellite receives the second message from the first terminal device.

[0191] The first terminal device sends a second message to the RAN device on the first satellite, and the RAN device forwards the second message to the control plane agent on the first satellite. In one possible implementation, the second message carries a service request of the first terminal device.

[0192] Specifically, the control plane agent decides whether to start offloading and the action of offloading, that is, decides whether to forward the service request of the terminal device to another communication device for processing or to process by the local core network agent based on the matching of the control plane message and the offloading rule.

[0193] In the embodiment of the application, the control plane agent offloads the second message forwarded by the RAN device, processes the second message that can match the offloading rule, and reduces the time delay of message processing.

[0194] Optionally, the embodiment shown in FIG. 4 further includes step 409. Step 409 can be performed after step 408.

[0195] 409、the first satellite sends a second message to the second satellite, and correspondingly, the second satellite receives the second message from the first satellite;

[0196] The first satellite splits the second message from the first terminal device to the second satellite according to the splitting rule, and the second satellite processes the second message.

[0197] Specifically, in a possible implementation, the second message is a control plane message of the first terminal device. The control plane agent of the first satellite sends a request for processing the control plane message to the control plane agent of the second satellite, and the control plane agent of the second satellite responds with an access permission. As shown in FIG. 6, the control plane agent of the first satellite sends a handover request to the RAN device of the second satellite through an NG interface, wherein the control plane agent of the second satellite has the capability of providing control plane message processing for the terminal device. The handover request includes one or more of the following: an identifier of the RAN device, an identifier of the first terminal device, and a handover condition. The identifier of the terminal device is used to instruct the RAN of the first satellite to trigger the first terminal device to perform a handover process, and the handover condition includes one or more of the following: time, a location of the first terminal device, a location of the first satellite, or a location of the second satellite. After the first terminal device accesses the RAN device of the second satellite, the control plane agent of the second satellite provides services for the first terminal device.

[0198] In another possible implementation, the second message is a control plane message of the first terminal device. The control plane agent of the first satellite sends a request for processing the control plane message to the control plane agent of the second satellite, and the control plane agent of the second satellite responds with an access permission. A transmission path is established between the control plane agent of the first satellite and the control plane agent of the second satellite, and the control plane agent of the first satellite sends the control plane message from the first terminal device to the control plane agent of the second satellite through the transmission path. A transmission path is established between the user plane agent of the first satellite and the user plane agent of the second satellite under the control of the two control plane agents, and the user plane agent of the first satellite splits the user plane message from the first terminal device to the user plane agent of the second satellite according to the configuration of the control plane agent of the first satellite, and the user plane agent of the second satellite performs data transmission based on the control plane agent of the second satellite.

[0199] In the embodiments of the present application, when the first satellite where the terminal device is located cannot provide services for the terminal device, the first satellite can split the data associated with the core network to other satellite nodes for processing, thereby reducing the time delay of message processing and improving the processing efficiency of terminal device messages.

[0200] Optionally, the embodiment shown in FIG. 4 further includes step 410. Step 410 can be performed after step 408.
