[0030] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] It should be noted that, in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0032] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0033] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "multiple" means two or more.

[0034] With the continuous development of communication networks, in addition to transmitting user-plane data, communication networks also need to forward and process non-user-plane data such as network data, Internet of Things (IOT) data, and Artificial Intelligence (AI) data.

[0035] In the current fifth generation mobile communication technology (5G) communication network, data forwarding and processing are mainly implemented by sinking to the user plane function (UPF) deployed at the edge of the network. Specifically, the UPF network element receives the service flow instructions issued by the session management function (SMF) to implement functions such as packet routing and forwarding, data packet inspection, data flow quality of service (QoS) processing, and traffic usage reporting.

[0036] In 5G networks, by sinking UPF to the edge of the network, devices closer to the edge of the network can participate in data processing and computing, reducing the burden on the core network. In addition, since data processing and computing are completed on devices close to the edge of the network element, the latency of data processing and computing can be reduced, allowing the 5G network to support low-latency and high-bandwidth services.

[0037] However, in the 5G network, only limited data forwarding functions are deployed at the edge, and unified edge orchestration cannot be performed. UPF cannot separate network data from user data, and can only achieve point-to-point connection on the user plane. It cannot support arbitrary topology caused by data distribution and aggregation during on-path analysis of different business data.

[0038] In order to solve the above problems, in the current network, the data plane can be separated from the user plane, and the data plane forwards and processes data other than user plane data. Specifically, DO and DA are set in the data plane of the sixth generation mobile communication technology (6G) network. DO is used to orchestrate data service tasks, and DA is used to process data service tasks. Optionally, a trusted anchor agent (TAA) and a data storage function (DSF) can also be set in the data plane. DSF is a storage plug-in of DA, used to store data. TAA is an agent of the security plane on the data plane, used to provide a security mechanism for the data plane to ensure the confidentiality, integrity and reliability of data.

[0039] However, the specific process of how to process and forward data service tasks according to the respective capabilities of DO and DA is not given at present. Therefore, how to process and forward data service tasks according to the respective capabilities of DO and DA has become a technical problem that needs to be solved urgently.

[0040] In order to solve the above technical problems, an embodiment of the present application provides a data sending method. After the data orchestration node obtains the data service task, it sends a path processing signaling to the target node that executes the data service task, so that the target node processes the data service task according to the route and data service capability of processing the data service task indicated by the path processing signaling. Based on this, in the embodiment of the present application, the data service task can be processed and forwarded based on the capabilities of the data orchestration node and the target node.

[0041] The data transmission method provided in the embodiment of the present application can be applied to Figure 1 In the communication system shown in FIG. Figure 1As shown, the communication system includes: a data orchestration node 101 and at least one data service node 102 .

[0042] The data orchestration node 101 is mainly used to implement topology construction, bearer management, and channel-processing signaling delivery functions.

[0043] The data service node 102 is used to report node capabilities, establish a bearer based on the orchestration of the data orchestration node, and process data service tasks based on the associated processing signaling sent by the data orchestration node.

[0044] The above-mentioned topology construction refers to the process of data orchestration node 101 constructing a network topology, which specifically includes: data orchestration node 101 obtains the data service capabilities and bearer information of data service nodes 102 in the entire network, and constructs a network topology based on the data service capabilities and bearer information of the data service nodes. The network topology is used to characterize the connection relationship between each node and the data service capability of each node.

[0045] The above-mentioned bearer management refers to the management of establishing and closing bearers between various nodes by the data orchestration node 101, which specifically includes: after receiving the data service task call, the data orchestration node 101 arranges the data service logic of the data service task according to the data service capabilities required by the data service task and the network topology of the network (the data service logic is used to characterize the order in which each data service node in the network processes the data service task, and the data service capabilities required to process the data service task). Based on the data service logic, the data orchestration node 101 determines the data service nodes that need to interact when processing the data service task, establishes bearers between these data service nodes that need to interact, and closes the bearer after the data service task is completed.

[0046] The above-mentioned sending of the associated processing signaling refers to the process of sending the associated processing signaling to the data service node after the data orchestration node 101 generates the associated processing signaling corresponding to the data service task, which specifically includes: the data orchestration node 101 determines the multiple target nodes that need to process the data service task, the order in which the multiple target nodes process the data service task, and the data processing capability of each target node to process the data service task. The data orchestration node 101 generates the associated processing signaling for each target node based on the above information and sends the corresponding associated processing signaling to the target node (the associated processing signaling is used to indicate the route and data service capability of the target node to process the data service task). In this way, the target node can process and forward the data service task according to the associated processing signaling, so that the data orchestration node 101 and the data service node 102 complete the data service task processing based on their respective capabilities.

[0047] It should be noted that Figure 1 This is just an exemplary framework diagram. Figure 1 The number of devices included in the Figure 1 In addition to the devices shown, the communication system may also include other devices, such as core network devices.

[0048] In some embodiments, the data orchestration node can be deployed in a core network device or a base station, and the data orchestration node is used to perform DO-related functions. The target node (and data service node) can be deployed in a core network device, a base station, or a terminal device, and the target node (and data service node) is used to perform DA-related functions.

[0049] The application scenarios of the embodiments of the present application are not limited. The system architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. It is known to those skilled in the art that with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0050] As an example, Figure 2 The process of data orchestration node and data service node interacting to process data service tasks is shown in FIG. Figure 2 As shown, the data orchestration node establishes the network topology of the network when it first accesses the network, and updates the network topology under corresponding conditions. After receiving the data service task call from the upper layer, the data orchestration node orchestrates the data service task and performs bearer management on the data service node based on the orchestrated data service task logic to establish a bearer between the nodes that process the data service task. After the bearer is established, the data orchestration node sends a path-associated processing signaling to the corresponding data service node. After receiving the path-associated processing signaling, the data service node listens to the data packet of the data service task, and after obtaining the data packet of the data service task, processes the data packet according to the path-associated processing signaling.

[0051] It should be noted that in the embodiment of the present application, the data arrangement node sends the corresponding data service node with the path processing signaling, including but not limited to: unicast delivery, recursive delivery and hybrid delivery. The data service node processes the data packet, including but not limited to: data collection, data forwarding, data storage, data preprocessing, and data analysis.

[0052] Figure 3 A schematic diagram of a data transmission method provided by the present application is shown in FIG. Figure 3 As shown, the data sending method includes the following S301-S303.

[0053] S301. The data orchestration node obtains a data service task.

[0054] Among them, the data service task refers to the task that needs to call the relevant nodes in the network to provide corresponding data services.

[0055] In some embodiments, the data service task acquired by the data orchestration node is a data service task called by the upper layer of the data plane through the data service API interface. Specifically, the upper layer sends a call request for the data service task to the data orchestration node through the data service API interface, and the data orchestration node acquires the data service task according to the call request.

[0056] It can be understood that in the embodiment of the present application, the data service task includes data in the data plane other than the user plane data, and may also include user data related to the user plane, and the present application does not limit this.

[0057] S302: The data orchestration node sends a path-associated processing signaling to the target node. Correspondingly, the target node receives the path-associated processing signaling from the data orchestration node.

[0058] The target node is a data service node that performs data service tasks; and the associated processing signaling is used to indicate the routing and data service capabilities of the target node for processing data service tasks.

[0059] In some specific implementations, the data orchestration node orchestrates the data service task according to the current network topology to determine the data service logic of the data service task; the data orchestration node determines the work of each target node according to the execution order of each target node in the data service logic and the data capability of each target node to execute the data service task (the work of the target node includes the routing of the target node processing the data service task and the data service capability of the target node processing the data service task). The data orchestration node generates a path-associated processing signaling according to the work of the target node and sends the path-associated processing signaling to the target node.

[0060] In some embodiments, the associated processing signaling includes a work field of the corresponding target node. The work field includes but is not limited to at least one of the following: an identifier of the target node, a data source node identifier, a capability identifier, and a data forwarding node identifier.

[0061] The data source node is used to represent the previous hop node of the target node, that is, from which nodes the target node needs to monitor the data packets of the data service task. In the case of multiple data source nodes, the data source node identifier includes the identifiers of the multiple data source nodes respectively.

[0062] The capability identifier is used to indicate which data service capabilities the target node needs to provide to process the data service task.

[0063] The data forwarding node identifier is used to represent the next hop node of the target node, that is, to which nodes the target node needs to forward the processed data packets after processing the data packets of the data service task. If there are multiple data forwarding nodes, the data forwarding node identifier includes the identifiers of the multiple data forwarding nodes respectively.

[0064] As an example, the data orchestration node can record the data service task and the data service logic of the data service task in the data service record table. The data service record table includes but is not limited to at least one of the following: data service task number, data service logic identifier, data service logic content; the data service logic content includes the identifier of the target node that processes the data service logic, the work of each target node, and the order and routing method of multiple target nodes processing the data service logic. The data service logic in the data service record table can also be replaced by the data service task, which is not limited in this application.

[0065] Optionally, the data service record table may be a chain structure, a tree structure or a directed graph, which is not limited in the present application.

[0066] It should be noted that the data orchestration node can orchestrate a data service task into one or more data service logics. After the orchestration is completed, the data orchestration node and the data service node can process each data service logic separately, or can process multiple data service logics of the data service task at the same time, which is not limited in this application.

[0067] S303: The target node processes the data service task based on the route and data service capability of the data service task indicated by the channel associated processing signaling.

[0068] In some embodiments, the target node processes the data service task in a manner including but not limited to: data collection, data forwarding, data storage, data preprocessing, and data analysis.

[0069] It should be noted that when the data transmission method provided in the embodiment of the present application is applied to a 6G network, the data arrangement node may be a DO in the network. The target node (data service node) may be a DA in the network. In addition, the data transmission method provided in the embodiment of the present application may also be applied to other types of networks, which is not limited in the present application.

[0070] In the embodiment of the present application, after the data orchestration node obtains the data service task, it sends a path-related processing signaling to the target node that executes the data service task, so that the target node processes the data service task according to the route and data service capability of processing the data service task indicated by the path-related processing signaling. Based on this, in the embodiment of the present application, the data service task can be processed and forwarded based on the capabilities of the data orchestration node and the target node.

[0071] It should be pointed out that in the embodiment of the present application, the data service task can be a data service task directly called by the upper layer, or it can be the data service logic of the data service task obtained after the data orchestration node orchestrates the called data service task. The present application does not limit this.

[0072] In some embodiments, the associated path processing signaling includes a first type of associated path processing signaling and a second type of associated path processing signaling.

[0073] The first type of path-associated processing signaling is used to indicate the route and data service capability of a target node for processing a data service task.

[0074] The second type of path-associated processing signaling is used to indicate the routing and data service capability of each of the multiple target nodes for processing the data service task.

[0075] The first type of path-associated processing signaling corresponds to a target node one-to-one, and each first type of path-associated processing signaling is used to indicate the routing and data service capabilities of the corresponding target node to process the data service task. The second type of path-associated processing signaling corresponds to a data service task (or data service logic), and the second type of path-associated processing signaling corresponds to all target nodes of the data service task.

[0076] Based on the different types of the above-mentioned channel-associated processing signaling, the embodiments of the present application provide the following channel-associated processing signaling delivery methods in different scenarios, namely: scenario 1, unicast delivery of channel-associated processing signaling; scenario 2, recursive delivery of channel-associated processing signaling; scenario 3, hybrid delivery of channel-associated processing signaling. Scenario 1, scenario 2 and scenario 3 are described below respectively.

[0077] Scenario 1: Unicast channel-associated signaling

[0078] Scenario 1 corresponds to the first type of path-associated processing signaling described above, that is, the data orchestration node sends the corresponding first type of path-associated processing signaling to each target node in a unicast manner.

[0079] In this scenario, combined with Figure 3 ,like Figure 4 As shown, the above S302 can be specifically implemented through the following S401.

[0080] S401: The data orchestration node sends a corresponding first type of associated processing signaling to each target node. Correspondingly, each target node receives the first type of associated processing signaling from the data orchestration node.

[0081] In some embodiments, the data orchestration node queries the data service task in the data service record table to determine the target node recorded in the data service logic content of the data service task and the work of the target node. The data orchestration node generates a first associated processing signaling corresponding to each target node according to the work of each target node, and sends the corresponding first associated processing signaling to each target node respectively.

[0082] The first type of associated processing signaling includes a target node work field and a data service task identifier. In the embodiment of the present application, the data service task identifier can also be replaced by a data service logic identifier.

[0083] As an example, Figure 5 As shown, the target nodes in the network that process the current data service task include: target node #1, target node #2, target node #3, and target node #4. The data orchestration node generates a first type of associated processing signaling corresponding to each target node, and sends the corresponding first type of associated processing signaling to each target node.

[0084] It should be pointed out that in different scenarios, the process of the target node processing the data service task after receiving the channel associated processing signaling is also different, which is explained below in conjunction with specific scenarios.

[0085] like Figure 4 As shown, in scenario 1, the process of the target node processing the data service task recorded in the above S303 can be implemented through the following S402-S405.

[0086] S402: The target node determines a previous hop node and a next hop node of the target node based on the route of the processing data service task indicated by the path-associated processing signaling.

[0087] In some embodiments, the target node parses the associated processing signaling to determine the data service task identifier and the work field. The target node further parses the work field, and determines whether the associated processing signaling is the associated processing signaling corresponding to the node according to the identifier of the target node in the work field; determines the previous hop node of the target node according to the data source node identifier in the work field; determines the next hop node of the target node according to the data forwarding node identifier in the work field; and determines the data processing capability required to be provided for the data service task according to the capability identifier in the work field.

[0088] It should be noted that, when the target node determines that the associated processing signaling is the associated processing signaling corresponding to the node, it continues to execute the following processes in S403-S405.

[0089] When the target node determines that the associated processing signaling is not the associated processing signaling corresponding to the node, it will no longer continue to execute the following processes in S403-S405 and go to the exception handling process.

[0090] S403: The target node monitors the data packet of the data service task sent by the previous hop node.

[0091] In scenario 1, the data packets of the on-link processing signaling and the data service task are sent separately. The data packet of the data service task includes the data service task identifier (or the identifier of the data service logic). After receiving the data packet, the target node determines whether the identifier in the data packet is consistent with the data service task identifier in the on-link processing signaling. If they are consistent, it is determined that the data packet is a data packet of the data service task processed by this node.

[0092] like Figure 5 As shown, after sending the in-path processing signaling to the target node, the data orchestration node sends the data packet of the data service task to the first target node #1 that processes the data service task, and the target node processes and forwards the data packet of the data service task in turn.

[0093] It should be noted that the previous hop node of the target node can be one or more. In the case where the data source node identifier in the work field parsed by the target node includes the identifiers of multiple data source nodes, the target node determines that the multiple data source nodes are all the previous hop nodes of the target node. The target node monitors the multiple previous hop nodes respectively until it receives a data packet sent by each previous hop node that matches the data service task identifier.

[0094] S404: The target node processes the data packet of the data service task based on the data service capability indicated by the channel associated processing signaling.

[0095] In some embodiments, the target node determines the data service capability for processing the data service task according to the capability identifier of the working field in the associated processing signaling. After that, the target node calls the data service capability to process the data packet of the data service task to obtain the processed data packet.

[0096] It should be noted that, when the target node has multiple previous hop nodes, the target node processes the data packets of the data service tasks sent by each previous hop node based on the data service capability indicated by the capability identifier in the working field.

[0097] S405: The target node forwards the processed data packet of the data service task to the next-hop node.

[0098] In some embodiments, the target node adds an identifier of the data service task to the processed data packet, and forwards the data packet with the identifier added to the next hop node.

[0099] It should be noted that, when the target node has multiple next hop nodes, the target node prunes the data packets of each next hop node respectively and sends the pruned data packets, which specifically includes: the target node deletes the information of other next hop nodes other than the target next hop node in the data packet of the processed data service task; the target next hop node is any node among the multiple next hop nodes. The target node sends the data packet after deleting the information of other next hop nodes to the target next hop node.

[0100] Scenario 2: Recursive channel processing signaling

[0101] Scenario 2 corresponds to the second type of path-associated processing signaling. That is, the data orchestration node sends the second type of path-associated processing signaling to the target node by recursive delivery. The second type of path-associated processing signaling corresponds to all target nodes that process the data service task.

[0102] In this scenario, combined with Figure 3 ,like Figure 6 As shown, the above S302 can be specifically implemented through the following S601.

[0103] S601: A data orchestration node sends a second type of associated processing signaling to a head node among multiple target nodes.

[0104] The head node is the target node that first processes the data service task. In the specific implementation, the head node can also be defined as a node without data source. The head node does not need to monitor the data packets of other data service nodes.

[0105] In some embodiments, the second type of associated processing signaling is integrated into a data packet of the data service task.

[0106] In some further embodiments, the second type of associated processing signaling includes multiple layers of fields, wherein one layer of fields corresponds to one target node, and each layer of fields is used to indicate the routing and data service capabilities of the corresponding target node in processing data service tasks.

[0107] In some embodiments, the data orchestration node queries the data service task in the data service record table to determine the target node recorded in the data service logic content of the data service task and the work of the target node. The data orchestration node writes the work field of each target node into the data packet in the order in which the target node processes the data service task, and each work field is a layer of fields.

[0108] The second type of associated processing signaling includes working fields of all target nodes and data service task identifiers.

[0109] As an example, Figure 7 As shown, the target nodes processing the current data service task in the network include: target node #1, target node #2, target node #3, and target node #4. The data scheduling node writes the working fields of target node #1 to target node #4 into the second type of associated path processing signaling, and sends a data packet carrying the second associated path processing signaling to the first target node #1 that performs the data service task.

[0110] like Figure 6 As shown, in scenario 2, the process of the target node processing the data service task recorded in the above S303 can be implemented through the following S602-S605.

[0111] S602: The target node receives a first data packet.

[0112] In some embodiments, after receiving the first data packet, the target node determines the data service task identifier in the data packet and parses the first layer work field of the data packet. The target node determines whether the associated processing signaling is the associated processing signaling corresponding to the node according to the identifier of the target node in the work field.

[0113] S603, when the first data packet is a data packet of a data service task and there is a field corresponding to the target node in the multi-layer field of the first data packet, the target node parses the field corresponding to the target node in the first data packet to determine the data service capability of the target node to process the first data packet and the next hop node of the target node.

[0114] In some embodiments, the target node determines the previous hop node of the target node based on the data source node identifier in the working field; determines the next hop node of the target node based on the data forwarding node identifier in the working field; and determines the data processing capability required for the data service task based on the capability identifier in the working field.

[0115] It should be noted that the previous hop node of the target node can be one or more. In the case where the data source node identifier in the work field parsed by the target node includes the identifiers of multiple data source nodes, the target node determines that the multiple data source nodes are all the previous hop nodes of the target node. The target node monitors the multiple previous hop nodes respectively until it receives a data packet sent by each previous hop node that matches the data service task identifier.

[0116] S604: The target node processes the first data packet based on the data service capability of the target node for processing the first data packet.

[0117] It should be noted that the specific implementation of S604 is similar to the specific implementation of S404 described above, and will not be repeated here.

[0118] In some embodiments, the target node deletes the field corresponding to the target node in the multi-layer field of the processed first data packet, so that the next hop node can directly determine the corresponding working field according to the first layer field in the received data packet.

[0119] S605: The target node forwards the processed first data packet to the next-hop node.

[0120] In some embodiments, when there are multiple next-hop nodes, the target node performs pruning processing on the data packets of each next-hop node respectively. The specific process of pruning processing can refer to the record in the above S405 and will not be repeated here.

[0121] Scenario 3: Hybrid delivery of channel-associated processing signaling

[0122] Among them, in scenario 3, the data orchestration node can flexibly choose to send the first type of associated processing signaling and the second type of associated processing signaling to flexibly adapt to the network environment of the network.

[0123] In some embodiments, the data orchestration node implements hybrid delivery of path-associated processing signaling through a path-associated processing table. Figure 3 ,like Figure 8 As shown, the process can be specifically implemented through the following S801-S803.

[0124] S801: The data orchestration node sends a path processing table establishment instruction information to the target node. Correspondingly, the target node receives the path processing table establishment instruction information from the data orchestration node.

[0125] The path-associated processing table establishment instruction information is used to instruct the establishment of a path-associated processing table.

[0126] The associated processing table is used for the target node to store at least one of the following according to the associated processing signaling: data service task identifier, data source of the data service task, and routing and data service capability of processing the data service task. The routing and data service capability of processing the data service task can be carried by the above-mentioned work field.

[0127] As an example, Fig. 9 As shown, the target nodes in the network include: target node #1, target node #2, target node #3, and target node #4. The data arrangement node sends the associated processing table establishment indication information to the four target nodes respectively, so that the four target nodes establish the associated processing table.

[0128] S802: In response to the indication information of establishing the associated path processing table, the target node establishes an associated path processing table.

[0129] S803: The target node sends the path processing table establishment completion information to the data orchestration node. Correspondingly, the data orchestration node receives the path processing table establishment completion information from the target node.

[0130] The path-associated processing table establishment completion information is used to indicate that the target node has established the path-associated processing table.

[0131] In some embodiments, after the target node completes the establishment of the associated processing table, the data orchestration node sends an associated processing signaling to the target node. In scenario 3, the data orchestration node can generate different types of associated processing signaling according to requirements, which is described below in conjunction with S804 and S805.

[0132] S804: The data orchestration node determines the type of channel associated processing signaling corresponding to the data service task.

[0133] In some embodiments, the type of associated processing signaling corresponding to the data service task is determined based on any one of the following: the reuse probability of the data service task; the complexity of the data service task; and the received indication information.

[0134] Specifically, the reuse probability of the data service task can be the reuse probability of the data service task calculated based on the frequency of occurrence of the data service task in a preset time period. Alternatively, it can be the reuse probability predicted after learning and predicting the data service call record using a neural network, which is not limited in this application, wherein the preset time period is the time period before the current time period.

[0135] The complexity of the above-mentioned data service task can be determined according to the number of target nodes processing the data service task, or can be determined according to the number of branches of the data service task, and this application does not limit this.

[0136] The received indication information may be an indication from an upper layer of the data orchestration node or an indication from a data service node.

[0137] In some embodiments, the data orchestration node may also send a data service status collection signaling to the data service node to collect data service tasks and data service task status corresponding to the second type of associated processing signaling. Which type of associated processing signaling to select is determined based on the resource utilization of the data service node.

[0138] S805: The data orchestration node generates a channel associated processing signaling based on the type of the channel associated processing signaling corresponding to the data service task.

[0139] In some embodiments, when the data orchestration node determines that the type of the associated processing signaling is a first type, the first type of associated processing signaling is generated.

[0140] When the data orchestration node determines that the type of the associated processing signaling is the second type, the second type of associated processing signaling is generated.

[0141] like Figure 8 As shown, in scenario 3, the process of the target node processing the data service task recorded in the above S303 can be implemented through the following S806-S808.

[0142] S806: The target node updates the associated processing table based on the associated processing signaling.

[0143] The associated processing table is used for the target node to store at least one of the following according to the associated processing signaling: a data service task identifier, a data source of the data service task, and a route and data service capability for processing the data service task.

[0144] In some embodiments, after receiving a data packet, the target node first analyzes whether the data packet includes the associated processing signaling, and if so, processes it based on the method described in scenario 2. If the associated processing signaling is not included, it is determined whether the data packet is a data packet of a data service task or a second type of associated processing signaling.

[0145] If it is a data packet of a data service task, the corresponding work field is searched from the associated processing table according to the data service task identifier in the data packet, and the data packet is processed according to the corresponding work field.

[0146] If it is the second type of associated path processing signaling, the associated path processing table is updated based on the second type of associated path processing signaling.

[0147] In some specific implementations, the target node updates the associated processing table in the following manner: the target node determines whether the current associated processing table includes an entry with the same data service task identifier as the associated processing signaling, and if so, updates the entry according to the associated processing signaling.

[0148] If it does not exist, a new table entry is added, and the relevant content in the channel-associated processing signaling is filled into the new table entry.

[0149] S807: After receiving the data service task, the target node obtains the route and data service capability of the target node processing the data service task corresponding to the data service task identifier from the updated associated processing table.

[0150] S808. The target node processes the data service task based on the routing and data service capabilities of the target node for processing the data service task.

[0151] The above describes in detail the manner in which the channel associated processing signaling is sent in different scenarios involved in the embodiments of the present application and the process in which the corresponding target node processes the data service task according to the channel associated processing signaling.

[0152] In the embodiment of the present application, both the path-associated processing signaling and the data packets of the data service tasks need to be transmitted on the bearers between the nodes. Before the data scheduling node sends the path-associated processing signaling, the bearers in the network can be managed first.

[0153] like Fig.10 As shown, the manner in which the data orchestration node manages the establishment of bearers between data service nodes can be specifically implemented through the following S1001-S1007.

[0154] S1001: A data orchestration node sends first bearer establishment indication information to a first node among target nodes. Correspondingly, the first node receives the first bearer establishment indication information from the data orchestration node.

[0155] Among them, the first node is a target node with which no bearer is established; the second node is a target node that needs to interact with the first node for data processing data service tasks; the first bearer establishment indication information is used to indicate the information of the first port that needs to be opened by the first node.

[0156] In some embodiments, the first bearer establishment indication information is further used to indicate at least one of the following: an authentication method of the first port; a closing method of the first port.

[0157] Among them, the authentication method is used to characterize the authentication method for authenticating another node that needs to establish a bearer. For example, when the second node establishes a connection with the first port of the first node, authentication is performed through a Token authentication connection, a two-end authentication connection based on a secure socket layer (SSL) key negotiation, etc. After the authentication is passed, the second node is allowed to establish a connection with the first port of the first node.

[0158] In some specific implementations, after acquiring the data service task, the data orchestration node determines at least one node pair that needs to interact when executing the data service task according to the data service logic of the data service task; the node pair includes two nodes that need to perform data interaction when processing the data service task. The data orchestration node determines the target node pair in at least one node pair based on the network topology; no bearer is established between the two nodes of the target node pair; the data orchestration node determines that one node in the target node pair is the first node and the other node is the second node. Thereafter, the data orchestration node sends first bearer establishment indication information to the first node.

[0159] S1002. In response to the first bearer establishment indication information, the first node opens a first port.

[0160] S1003: The first node sends first bearer establishment confirmation information to the data orchestration node. Correspondingly, the data orchestration node receives the first bearer establishment confirmation information from the first node.

[0161] The first bearer establishment confirmation information is used to indicate that the first port has been opened.

[0162] In some embodiments, the first bearer establishment confirmation information carries a port identifier of the first port.

[0163] S1004: The data orchestration node sends second bearer establishment indication information to the second node. Correspondingly, the second node receives the second bearer establishment indication information from the data orchestration node.

[0164] The second bearer establishment indication information is used to instruct the second node to establish a connection with the first port.

[0165] S1005. In response to the second bearer establishment indication information, the second node establishes a connection with the first port.

[0166] In some embodiments, the second bearer establishment indication information includes a port identifier of the first port and an authentication method of the first port.

[0167] The second node initiates connection authentication to the first port according to the port identifier of the first port and the authentication mode of the first port, and establishes a connection with the first port after the authentication passes.

[0168] S1006: The second node sends second bearer establishment confirmation information to the data orchestration node. Correspondingly, the data orchestration node receives the second bearer establishment confirmation information from the second node.

[0169] The second bearer establishment confirmation information is used to indicate that a connection has been established with the first port.

[0170] After the data scheduling node receives the first bearer establishment indication information and the second bearer establishment indication information respectively, it determines that the bearer between the first node and the second node has been established. At this time, the data scheduling node updates the bearer record table to record the real-time bearer status of the network.

[0171] S1007: The data orchestration node updates the bearer record table based on the second bearer establishment confirmation information.

[0172] The bearer record table is used to record the bearer information established between various nodes in the network.

[0173] In some embodiments, the bearer record table includes but is not limited to the following contents: a sending end, a receiving end, port information, and a port closing method.

[0174] As an example, in combination with the above S1001-S1006, the sending end is the first node, the receiving end is the second node, the port information is the first port, and the port closing mode is the closing mode indicated by the first bearer establishment indication information.

[0175] In some embodiments, the data orchestration node may update the network topology in addition to updating the bearer record table.

[0176] Since establishing a bearer between data service nodes requires occupying the resources of the data service nodes, in order to reduce resource occupation, the embodiment of the present application provides the following two bearer closing methods, namely: method 1, the data service node actively closes the bearer; and method 2, the data orchestration node instructs the service node to close the bearer. The following describes method 1 and method 2 in detail.

[0177] Method 1: Data service node actively closes the bearer

[0178] like Fig.11 As shown, the process of the data service node actively closing the bearer includes the following S1101 and S1102.

[0179] S1101: A target node sends first indication information to a data orchestration node. Correspondingly, the data orchestration node receives the first indication information from the target node.

[0180] The first indication information is used to indicate that the target node has closed the bearer.

[0181] In some embodiments, the first indication information is sent when the target node satisfies a second preset condition.

[0182] As an example, the second preset condition includes at least one of the following: a connection establishment duration of the target node's bearer is greater than or equal to a third preset duration, and an idle duration of the target node's bearer is greater than or equal to a fourth preset duration.

[0183] As a specific implementation manner, the target node determines that the closing mode indicated by the first bearer establishment indication information is the ports that are automatically closed, and monitors these ports in real time.

[0184] When the target node monitors a port that meets the second preset condition, it closes the bearer of the port and sends first indication information to the data orchestration node to indicate that the bearer has been closed.

[0185] S1102: The data orchestration node updates the bearer record table based on the first indication information.

[0186] The bearer record table is used to record the bearer information established between various nodes in the network.

[0187] In some embodiments, the data orchestration node may update the network topology in addition to updating the bearer record table.

[0188] Method 2: The data orchestration node instructs the service node to close the bearer

[0189] like Fig.12 As shown, the process in which the data orchestration node instructs the service node to close the bearer includes the following S1201-S1204.

[0190] S1201: A data orchestration node sends second indication information to a fourth node. Correspondingly, the fourth node receives the second indication information from the data orchestration node.

[0191] The second indication information is used to instruct the fourth node to close the bearer; the fourth node is one of the target nodes.

[0192] In some embodiments, the data orchestration node sends second indication information to the fourth node when the first preset condition is met.

[0193] As an example, the first preset condition includes at least one of the following: a connection establishment duration of the bearer is greater than or equal to a first preset duration, and an idle duration of the bearer is greater than or equal to a second preset duration.

[0194] As a specific implementation method, the data orchestration node determines the bearer to be closed, and queries the bearer record table to determine the bearer information of the bearer. The bearer information includes the port information of the sender of the bearer (ie, the fourth node). The data orchestration node sends the second indication information to the fourth node.

[0195] S1202. In response to the second indication information, the fourth node closes the bearer.

[0196] S1203: The fourth node sends bearer closing confirmation information to the data orchestration node. Correspondingly, the data orchestration node receives the bearer closing confirmation information from the fourth node.

[0197] The bearer closing confirmation information is used to indicate that the fourth node has closed the bearer.

[0198] In some embodiments, the bearer closing confirmation information includes the port information that is closed this time.

[0199] S1204: The data orchestration node updates the bearer record table based on the bearer closing confirmation information.

[0200] The bearer record table is used to record the bearer information established between various nodes in the network.

[0201] In some embodiments, the data orchestration node may update the network topology in addition to updating the bearer record table.

[0202] The above describes the relevant contents related to bearer management in the embodiments of the present application.

[0203] In the embodiment of the present application, whether the data orchestration node orchestrates the data service logic of the data service task, or establishes the bearer and sends the channel-associated processing signaling, it needs to be implemented based on the network topology. Therefore, the embodiment of the present application provides a process for building a network topology.

[0204] like Fig.13 As shown, the process of constructing a network topology provided in the embodiment of the present application can be implemented through the following S1301-S1302, which is described in detail below.

[0205] S1301: A target node sends capability reporting information to a data orchestration node. Correspondingly, the data orchestration node receives capability reporting information from multiple data service nodes in the network.

[0206] The capability reporting information includes at least one of the following: node identification, node type, data service capability of the node, and bearer information of the node.

[0207] The node identifier is used to identify the data service node, and may be, for example, the Internet protocol (IP) address of the data service node, the unique user identification (UID) of the data service node, a character string of the data service node, and the like.

[0208] The node type is used to characterize the classification of data service nodes. For example, a data service node is a terminal, a base station, a core network device, etc.

[0209] The data service capability of a node is used to record the data service capability of the node, such as whether the node has forwarding capability and / or the maximum forwarding amount; whether the node has data collection capability and / or the type of data that can be collected; whether the node has preprocessing capability and / or processor parameters; whether the node has storage capability and / or the maximum storage amount, database format; whether the node has analysis capability and / or processor parameters, memory parameters. As an example, the target node can carry the data service capability of the node through the capability matrix.

[0210] The node's carrying information is used to record the node's carrying capacity, the node's neighboring node identifiers, and other information.

[0211] S1302: The data orchestration node builds a network topology based on the capability reporting information of multiple data service nodes.

[0212] The network topology includes the bearer information between data service nodes in the network and the data service capabilities of each data service node.

[0213] As an embodiment, when topology information of the data service node exists in the current network topology, the data orchestration node updates the topology information of the data service node in the current network topology based on the capability reporting information of the data service node.

[0214] In the case that the topology information of the data service node does not exist in the current network topology, the data orchestration node adds the topology information of the data service node in the current network topology based on the capability reporting information of the data service node.

[0215] The data orchestration node can construct the network topology by constructing the network topology and capability topology respectively. The network topology is used to characterize the structure of the network and the node connection relationship. The capability topology is used to characterize the capability relationship of each node.

[0216] The data orchestration node may construct a network topology or may only construct a network topology, which uniformly represents the network structure, node connection relationships, and capability relationships of each node.

[0217] As an example, the network topology and / or capability topology may be represented in the form of an adjacency matrix, an association matrix, a multiple link, etc.

[0218] It should be noted that in the embodiment of the present application, the process of constructing the topology can be initiated by the data orchestration node or by the data service node.

[0219] In the case initiated by the data orchestration node, such as Fig.13 As shown, the process also includes S1300.

[0220] S1300: The data orchestration node sends third indication information to multiple data service nodes. Correspondingly, the multiple data service nodes receive the third indication information from the data orchestration node.

[0221] The third indication information is used to instruct the data service node to report capability information.

[0222] The data service node sends capability reporting information to the data orchestration node in response to the third indication information. Correspondingly, the data orchestration node receives the capability reporting information from the data service node.

[0223] The third indication information may specifically include an identifier of the data orchestration node and a requirement for capability information reported by the data service node.

[0224] The identifier of the data orchestration node may be the IP address of the data orchestration node, the unique identifier UID of the data orchestration node, or the character string of the data orchestration node. The requirement for capability information reported by the data service node is used to characterize the manner in which the data service node needs to report capability information, such as reporting incremental information or reporting full information.

[0225] As an example, when a data orchestration node accesses the network for the first time, or when the data orchestration node regularly updates and maintains the network topology, the process of building the topology is initiated by the data orchestration node.

[0226] In the case of being initiated by a data service node, the data service node directly sends capability reporting information to the data orchestration node.

[0227] As an example, when a data service node accesses the network for the first time, or when the function of the data service node is updated, the topology is updated in a manner initiated by the data service node.

[0228] It is understandable that, in order to realize the above functions, the communication device includes a hardware structure and / or software module corresponding to each function. It should be easily appreciated by those skilled in the art that, in conjunction with the algorithm steps of each example described in the embodiments of the present application, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the present application.

[0229] The embodiment of the present application can divide the functional modules of the communication device according to the above method embodiment. For example, each functional module can be divided corresponding to each function, or two or more functions can be integrated into one functional module. The above integrated module can be implemented in the form of hardware or software. It should be noted that the division of modules in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation. The following is an example of dividing each functional module corresponding to each function.
