[0017] In the third aspect, processing the second data according to the at least one identification information and the corresponding at least one value includes: sending the second data to the first node in the first data chain according to the first identification information and the first value.

[0018] Optionally, the nodes in the first data chain are all data transmission function network elements, and the data transmission function network elements are used for transmitting and processing the first data; or the nodes in the first data chain are all data processing function network elements, and the data processing function network elements are used for processing the first data.

For ease of description, the first node is taken as an example in the following description.

[0027] In the above solution, the first node processes the first data and sends the fourth data to the data transmission function network element, and the data transmission function network element determines the transmission object of the fourth data according to the values and the identifier of the data chain.

[0065] In order to facilitate understanding of the embodiments of the present application, the following points are first explained.

[0066] I. Unless otherwise stated, the meaning of "a plurality of" is two or more.

[0067] II. If there is no special description and no logical conflict, the terms and / or descriptions between different embodiments of the present application are consistent and can be mutually referred to. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0068] III. The various numerical numbers involved in the present application are only used for differentiation for the convenience of description, and are not used to limit the protection scope of the present application. The size of the serial numbers involved in the present application does not mean the execution order. The execution order of each process should be determined according to its function and inherent logic. For example, the terms "first", "second", "third", "fourth" and other various term labels in the specification and claims of the present application and the drawings (if any) are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. Among them, the data thus used can be interchanged under appropriate circumstances, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

[0069] Meanwhile, any embodiment or design scheme described as "exemplary" or "for example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the use of "exemplary" or "for example" and the like is intended to present the relevant concept in a specific manner for ease of understanding.

[0070] IV. The terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0071] Five, in this application, "for indicating" can be understood as "enabling", "enabling" includes direct enabling and indirect enabling. When describing that a certain information is used to enable A, it can include that the information directly enables A or indirectly enables A, and it does not mean that A must be carried in the information.

[0072] The information enabled by the information is called to-be-enabled information, and in the specific implementation process, there are many ways to enable the to-be-enabled information, for example but not limited to, the to-be-enabled information can be directly enabled, such as the to-be-enabled information itself or an index of the to-be-enabled information. The to-be-enabled information can also be indirectly enabled by enabling other information, where the other information and the to-be-enabled information have an association relationship. The to-be-enabled information can also be enabled only in part, and the other part of the to-be-enabled information is known or agreed in advance. For example, the enabling of a specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, specified by a protocol), thereby reducing the enabling overhead to a certain extent. At the same time, the common part of each information can be identified and uniformly enabled to reduce the enabling overhead caused by separately enabling the same information.

[0073] In addition, "indicating" can include direct indication, indirect indication, display indication, and implicit indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0074] In this application, the information indicated by the indication information is called to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only in part, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, specified by a protocol), thereby reducing the indication overhead to a certain extent. In addition, the to-be-indicated information can be sent as a whole, or can be sent separately in multiple sub-information, and the sending period and / or sending time of these sub-information can be the same or different.

[0075] Six, in this application, "pre-configuration" can include pre-definition, for example, protocol definition. Wherein, "pre-definition" can be realized by pre-saving the corresponding code, table or other information indicating manner in the device (for example, including each network element), and the specific implementation manner of the application is not limited.

[0076] VII. The term "storage" or "preservation" in this application can refer to storage in one or more memory devices. These memory devices can be separately configured or integrated into an encoder, decoder, processor, or communication device. Alternatively, some memory devices can be separately configured, while others can be integrated into a decoder, processor, or communication device. The type of memory can be any form of storage medium, and this is not limited.

[0077] 8. The "protocol" used in this application may refer to standard protocols in the field of communications, such as fourth-generation (4G) protocols. th Generation 4G network, fifth generation (5G) network th This application does not limit the scope to network protocols such as generation (5G), NR, 5.5G, and related protocols applied in future communication networks.

[0078] 9. The arrows or boxes indicated by dashed lines in the schematic diagrams in the accompanying drawings of this application represent optional steps or optional modules.

[0079] 10. Unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship. For example, A / B can mean A or B. In this application, "and / or" is merely a description of the relationship between the related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. A and B can be singular or plural.

[0080] XI. In this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include direct transmission via the air interface or indirect transmission by other units or modules via the air interface. "Receive information from YY" can be understood as the source of the information being YY, which may include direct reception from YY via the air interface or indirect reception from YY by other units or modules via the air interface. "Send" can also be understood as the "output" of a chip interface, and "receive" can also be understood as the "input" of a chip interface. In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via a bus, wiring, or interface.

[0081] First, the communication system to which the embodiments of this application are applicable will be described.

[0082] FIG. 1 is a schematic diagram of a communication system 100 to which embodiments of the present application are applied. As shown in FIG. 1, the communication system 100 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, collectively referred to as 110) and at least one terminal device (e.g., 120a-120j, collectively referred to as 120). The RAN 100 can further include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 1), etc. The terminal devices 120 are wirelessly connected to the RAN nodes 110. The RAN nodes 110 are connected to the CN 200 by wire or wirelessly. The core network devices in the CN 200 and the RAN nodes 110 in the RAN 100 can be different physical devices, or can be the same physical device integrated with the logical functions of the CN and the RAN, respectively.

[0083] The RAN 100 can be a third generation partnership project (3GPP) related cellular system, such as a 4G, 5G communication system or a future-oriented evolved system. The RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (C-RAN or CRAN), a wireless fidelity (Wi-Fi) system. The RAN 100 can also be a communication system in which two or more of the above systems are fused. rd The RAN 100 can be a third generation partnership project (3GPP) related cellular system, such as a 4G, 5G communication system or a future-oriented evolved system. The RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (C-RAN or CRAN), a wireless fidelity (Wi-Fi) system. The RAN 100 can also be a communication system in which two or more of the above systems are fused.

[0084] The RAN nodes 110, which can also be referred to as access network devices, RAN entities, or access nodes, etc., are configured to help terminal devices to access wirelessly. The RAN nodes 110 in the communication system 100 can be of the same type or of different types. In some scenarios, the roles of the RAN nodes 110 and the terminal devices 120 are relative, for example, the network element 120i can be a helicopter or a drone, which can be configured as a mobile base station. For those terminal devices 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal device. The RAN nodes 110 and the terminal devices 120 are sometimes collectively referred to as communication apparatuses, for example, the network elements 110a and 110b can be understood as communication apparatuses with base station functions, and the network elements 120a-120j can be understood as communication apparatuses with terminal functions.

[0085] In one possible scenario, the RAN node can be a base station (BS), an evolved Node B (eNB), an access point (AP), a transmission point (TP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a future communications network, a base station in a future mobile communications system, or an access node in a Wi-Fi 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.

[0086] The RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. 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 such as a cloud platform. The RAN node in this application can also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

[0087] In another possible scenario, multiple RAN nodes cooperate to assist terminal devices to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, the RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

[0088] The CU (or CU-CP and CU-UP), DU or RU can also have different names in different communication systems, 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, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU and 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 present application can be applied to V2X scenarios.

[0098] In order to facilitate understanding of the embodiments of the present application, the terms involved in the embodiments of the present application will be briefly described first.

[0099] 1) Definition of perception

[0100] Wireless sensing is to sense by using wireless signals. Sensing is a process of collecting, processing collected data, and generating sensing results, such as judging the distance, shape, type, etc. of a surrounding obstacle by collecting data, and judging the breathing frequency, heartbeat, etc. of a monitored object by collecting data. The collected data can be data collected by a sensor, or data collected by a wireless signal.

[0101] 2), sensing entity (SE)

[0102] The sensing entity can send and / or receive sensing signals, and can also send sensing capabilities to a sensing control entity or an access management entity. In embodiments of the present application, the sensing capabilities can include one or more of the following capabilities:

[0103] Layer 1 (L1) sensing capability, for sensing raw data, which refers to basic information of the sensing signal, such as one or more of the following: amplitude, phase, whether the sensing signal is an I-channel signal or a Q-channel signal, etc.

[0104] Layer 2 (L2) sensing capability, for sensing measurement data, which refers to data obtained by processing raw data, and used to represent measurement dimensions, and can include but is not limited to one or more of the following: time delay of a sampling point, receiving angle of the sensing signal, signal strength of the sensing signal, Doppler (i.e. frequency offset of the sensing signal), position of a target object, speed of the target object, etc. A sampling point refers to a signal value at a certain time or position selected during the discretization of continuous signals in the signal processing process.

[0105] Layer 3 (L3) sensing capability, for processing sensing data to obtain sensing results, the sensing data can be raw data and / or measurement data, and the sensing results can include but are not limited to one or more of the following: distance between the sensing entity and the target object, speed of the target object, position of the target object, angle between the sensing entity and the target object, movement path of the target object, breathing frequency of the target object, heartbeat of the target object, etc.

[0106] The perception entity is a logical entity, which can also be referred to as a logical perception entity. The perception entity can be deployed on a network device or a terminal device, that is, a network device or a terminal device with perception capability can serve as a perception entity, and the perception entity can be a network device or a terminal device with perception capability. The network device or the terminal device can have the above-mentioned three capabilities, or have one or several capabilities. For example, some terminal devices with weak computing power have L1 perception capability but do not have L2 perception capability and L3 perception capability. For another example, some network devices have the above-mentioned three capabilities. The perception entity can also be deployed independently.

[0107] The perception entity described above can also include a perception control entity and a perception processing entity. The perception control entity can be used to implement the control plane function of the perception service, for example, to receive the perception capability information of the perception entity, and to orchestrate the perception service based on the perception capability information of the perception entity. The perception processing entity can be used to implement the data plane function of the perception service, for example, to process the perception data of the perception service to obtain the perception result of the perception service. After the control plane function of the perception service and the data plane function of the perception service are deployed independently, the number of control plane function entities and data plane function entities can be flexibly configured and adjusted according to the resources and service conditions; secondly, the attack on the data plane will not affect the control plane, and vice versa, thereby improving the reliability and security of the perception service.

[0108] The above-mentioned orchestration of the perception service can include selecting a sending perception entity and a receiving perception entity, and the sending perception entity and the receiving perception entity can be the same perception entity. The sending perception entity is the sending end of the perception signal, and is used to send the perception signal. The receiving perception entity is the receiving end of the perception signal, and is used to receive the perception signal.

[0109] The above-mentioned processing of the perception data can include processing the original data to obtain measurement data, and / or processing the measurement data to obtain the perception result. The measurement data can be obtained by processing the original data, or can be obtained by the perception entity.

[0110] The two names of the sensing control entity and the sensing processing entity are used for example and do not constitute a limitation on the embodiments of the present application. With the development of communication technology and sensing technology, the two modules can adopt other names. For example, the sensing control entity can also be described as a sensing service control function (SSCF) network element, or a sensing service control network element, or a sensing control network element, etc. The sensing processing entity can also be described as a sensing data processing function (SDPF) network element, or a sensing data processing network element, or a sensing processing network element, a sensing data function network element, a data function network element, etc. For the convenience of description, the sensing control entity is described as an SSCF and the sensing processing entity is described as an SDPF in the following embodiments.

[0111] The embodiments of the present application take the introduction of the SSCF and the SDPF in the core network architecture of the 5G system as an example to better compatible with the 5G system so as to smoothly evolve to the future communication network. Referring to FIG. 2.

[0112] FIG. 2 is a schematic diagram of a network architecture 200 according to an embodiment of the present application. As shown in FIG. 2, the access and mobility management function (AMF), the network exposure function (NEF), the policy control function (PCF), etc. can be coupled to the SBI bus through a service-based interface (SBI), or in other words, the AMF, the NEF, the PCF, etc. can perform signaling interaction through the SBI bus.

[0113] The RAN node can connect the SSCF through the AMF (such as an N2 interface) or directly connect the SSCF (such as an Ns interface). The terminal can connect the SSCF through the RAN node, or the terminal can connect the SSCF through the AMF. The SDPF is coupled to the SBI bus through the SSCF. In addition, the SSCF and the AMF can communicate based on the SBI, and there is a dedicated interface between the SSCF and the SDPF.

[0114] In summary, the RAN node can directly perform control plane communication with the SSCF or perform control plane communication with the SSCF through the AMF (for example, transmit control plane messages, etc., such as control messages). The SDPF can be coupled to the SBI bus or not be coupled to the SBI bus. The RAN can directly perform data plane communication with the SDPF (for example, transmit data, etc.).

[0115] The network element can be a network element in a hardware device, a software function running on a dedicated hardware, or a virtualized function instantiated on a platform (e.g., a cloud platform). The functional network element can be divided into one or more services, and further, there can be services independent of the network function. The instance of the functional network element, or the instance of the service included in the functional network element, or the instance of the service independent of the network function can be referred to as a service instance.

[0116] The names of the network elements shown in FIG. 2 are only names, and the names do not limit the functions of the network elements. In the 5G network and future other networks, the network elements can also be other names, and the embodiments of the present application do not specifically limit this. For example, in future communication networks, part or all of the network elements can continue to use the terms in 5G, or can be other names, etc. This is uniformly described below, and the following will not be repeated.

[0117] In addition, the "network element" in this paper can also be referred to as a network function instance (NFI), a network function (NF), a device, an apparatus, or a module, etc. The present application does not specifically limit this. In addition, the above names are only defined to facilitate the differentiation of different functions, and should not constitute any limitation. The present application does not exclude the possibility of using other names in the 5G network and future other networks. For example, in future communication networks, part or all of the network elements can continue to use the terms in 5G, or can use other names, etc. The interface name between the above network elements is only an example, and the name of the interface in the specific implementation can be other names, and this is not specifically limited. In addition, the name of the message (or signaling) transmitted between the above network elements is also only an example, and the function of the message itself does not constitute any limitation.

[0118] In the network architecture 200, the RAN node transmits data (perception data or AI data or IOT data, etc.) through the DCP, and the SDPF obtains the data through the DCP. For example, the RAN node publishes the data in the form of a topic to the DCP, and the SDPF obtains the data from the DCP according to the topic.

[0119] However, the above data transmission process is relatively complex. For example, the SSCF arranges the SDPF1 and the SDPF2, and sends the subscribed / published topic and the related operation instruction to the SDPF1 and the SDPF2 respectively. For the data source, when the data is ready, the data source is ready to start publishing according to the assigned topic1, the SDPF1 subscribes to the topic1, obtains the data and processes the data, and publishes the data with the topic2, the SDPF2 subscribes to the topic2, and the DCP transmits the data to the SDPF2. The DCP needs to transmit the data according to the topic. With the increasing number of nodes in the data chain, the complexity of the data transmission process is high. Therefore, the present application provides a communication method and a communication device, which can reduce the complexity of the data transmission process.

[0120] For the convenience of understanding and description, the following is described from the following aspects: a communication system, a communication method and a communication device.

[0121] I. Communication system

[0122] To solve the above technical problems, the present application provides a communication system, which can be seen from FIG. 3.

[0123] FIG. 3 is a schematic diagram of the architecture of the communication system 300 according to an embodiment of the present application. As shown in FIG. 3, the communication system 300 includes a first device, a service processing function network element and a data transmission function network element.

[0124] Optionally, the communication system 300 can further include a first node, which is configured to process the first data. For example, the first node can be configured to perform transmission processing or data processing on the first data. When the first node performs data processing on the first data, the first node can be a data processing function network element. When the first node performs transmission processing on the first data, the first node can be a data transmission function network element.

[0125] The first device is a source of the first data, and the first device generates the first data and sends the first data to the data transmission function network element. As shown by the number 1 in FIG. 3, the first device sends the first data to the data transmission function network element. In one possible example, the first device can be a device on the terminal device side or a device on the RAN side, which is not limited in this regard.

[0126] The data transmission function network element is a network element with a data transmission function, for example, the data transmission function network element performs transmission processing on data from other devices. As shown by the numbers 2 and 3 in FIG. 3, the data transmission function network element sends the first data to the first node, and the first node sends data obtained by processing the first data to the data transmission function network element. In one possible example, the data transmission function network element can be a DCP network element (which can also be replaced by other terms).

[0127] The service processing function network element is a network element with a service arrangement function. For example, the service processing function network element determines a transmission path of data of a service. For example, the service processing function network element determines a transmission object of first data. For example, the service processing function network element determines that the first data needs to pass through processing of a first node. A possible example is that the service processing function network element can be an SCCF.

[0128] In other words, the service processing function network element determines a data chain for processing the first data. For example, the service processing function network element determines a first data chain. The first data chain includes a first node and a second node. The first node and the second node process the first data. For example, the first node processes the first data. The second node processes data obtained by processing the first data by the first node.

[0129] The data processing function network element is a network element with a data processing function. For example, the data processing function network element is used for data processing of received data. For example, the data processing function network element changes the format or content of the data. Alternatively, the data processing function network element processes the data. A possible example is that the data processing function network element can be an SDPF.

[0130] In order to reduce the complexity of the data transmission process, the service processing function network element can indicate the transmission path of the data by indicating the identification information of the data chain (which can include the identification or index of the data chain, which is not limited) and the corresponding value. The data transmission function network element can transmit data according to the identification information of the data chain and the corresponding value. The description of the identification information of the data chain and the value can refer to Table 1. The content shown in Table 1 is only an example and is not limited.

[0131] Table 1

[0132] As shown in Table 1, the identification information A identifies the data chain T. The data chain T includes the node T1, the node T2, and the node T3. Each node corresponds to a value.

[0133] The value a1 and the identification information A are used to indicate the node T1.

[0134] The value a2 and the identification information A are used to indicate the node T2. The value a2 is determined according to the value a1. For example, the value a2 = the value a1-1, or the value a2 = the value a1+1, or the value a2 = the value a1-2, or the value a2 = the value a1+2, and the like.

[0135] The numerical value a3 and the identification information A are used to indicate the node T3. The numerical value a3 is determined according to the numerical value a2, for example, a3=a2-1, or a3=a2+1, or a3=a2-2, or a3=a2+2, and the like.

[0136] In the embodiment of the present application, the service processing function network element can send information including the identification information of the data chain and the corresponding numerical value to the first device, the first device carries the identification information of the data chain and the corresponding numerical value in the header of the data to be processed, and sends the data (including the identification information of the data chain and the corresponding numerical value) to the data transmission function network element. The data transmission function network element completes the transmission of the data according to the identification information of the data chain and the corresponding numerical value. For example:

[0137] The data transmission function network element determines the node T1 according to the identification information A and the numerical value a1, and sends the data Q2 to the node T1. The data Q2 includes the data Q1, the identification information A and the numerical value a1. The data Q1 is the data to be processed.

[0138] The node T1 processes the data Q1, and sends the data Q4 to the data transmission function network element. The data Q4 includes the data Q3, the identification information A and the numerical value a2. The data Q3 is the data obtained by the node T1 processing the data Q1.

[0139] The data transmission function network element determines the node T2 according to the identification information A and the numerical value a2, and sends the data Q4 to the node T2.

[0140] The node T2 processes the data Q3, and sends the data Q6 to the data transmission function network element. The data Q6 includes the data Q5, the identification information A and the numerical value a3. The data Q5 is the data obtained by the node T2 processing the data Q3.

[0141] The data transmission function network element determines the node T3 according to the identification information A and the numerical value a3, and sends the data Q6 to the node T3.

[0142] The node T3 processes the data Q6, and sends the data Q8 to the data transmission function network element. The data Q8 includes the data T7, the identification information A and the numerical value a4. The data Q7 is the data obtained by the node T3 processing the data Q5.

[0143] Through the above process, the data transmission function network element does not need to transmit the first data according to the subject of the first data, and the data transmission function network element does not need to perform operations such as publishing and subscribing of the subject, which can reduce the complexity of the data transmission process.

[0144] In the embodiment of the application, the identification information of the data chain is determined according to the identification information of each node (a node related to data processing) in the data chain and a coprime array. The coprime array includes at least two coprime numbers satisfying the coprime relationship. Any two numbers in the coprime array satisfy the coprime relationship, that is, the coprime array includes at least two coprime numbers, for example, the coprime array includes {3, 4}, or the coprime array includes {3, 4, 5}, or the coprime array includes {3, 4, 5, 7}, or the coprime array includes {3, 4, 5, 7, 11}, and the like.

[0145] For example, the coprime array includes {10, 11, 13, 17, 19, 23, 29, 31}, the data chain T includes node T1, node T2, and node T3, the identification information of node T1 is 7, the identification information of node T2 is 5, and the identification information of node T3 is 4. The service processing function network element determines the identification information of the data chain T according to the Chinese remainder theorem (CRT). The data chain T includes three nodes, and three prime numbers in the coprime array are selected: 13 (corresponding to 7, 7 is used to determine node T1), 11 (corresponding to 5, 5 is used to determine node T2), and 10 (corresponding to 4, 4 is used to determine node T3).

[0146] For example:

[0147] m1 = 13, m2 = 11, m3 = 10, s1 = 7, s2 = 5, s3 = 4;

[0148] P = m1*m2*m3 = 13*11*10 = 1430;

[0149] M1 = P / m1 = 110, M2 = P / m2 = 130, M3 = P / m3 = 143;

[0150] M1 -1 = 11, M2 -1 = 5, M3 -1 = 7; (1)

[0151] According to formula (1), the identification information of the data chain T is represented as: [(s1*M1*M1 -1 )+(s2*M2*M2 -1 )+(s3*M3*M3 -1)] mod 1430 = 1424. Wherein, s1 = 1424 mod 13 = 7, s2 = 1424 mod 11 = 5, s3 = 1424 mod 10 = 4. Mod represents remainder. M1 -1 represents inverse element of M1 to m1, M2 -1 represents inverse element of M2 to m2, M3 -1 represents inverse element of M3 to m3.

[0152] The service processing function network element can determine the identification information of the data chain T according to the above calculation, and the data transmission function network element can determine the identification information of each node in the data chain T according to the above calculation. Based on the above method, the identification information of the data chain is determined, and the data transmission function network element does not need to transmit data according to the theme, which can reduce the complexity of the data transmission process, for example, the data transmission function network element does not need to perform theme publishing and subscription operations again.

[0153] In one possible implementation, the numerical value corresponding to the identification information can be used to indicate the co-prime number corresponding to a certain node in the co-prime number array.

[0154] For example, the identification of the data chain T is 1424, and the numerical value a1 = 3:

[0155] The data transmission function network element determines the prime number 13 according to the numerical value a1, and obtains 7 based on the remainder calculation between 1424 and 13. The data transmission function network element sends data Q2 to the node T1.

[0156] The node T1 sends data Q4 to the data transmission function network element, and the data Q4 includes the data Q3, the identification information of the data chain T and the numerical value a2. The numerical value a2 = 2.

[0157] The data transmission function network element determines the prime number 11 according to the numerical value a2, and obtains 5 based on the remainder calculation between 1424 and 11. The data transmission function network element sends data Q4 to the node T2.

[0158] The node T2 sends data Q6 to the data transmission function network element, and the data Q6 includes the data Q5, the identification information of the data chain T and the numerical value a3. The numerical value a3 = 1.

[0159] The data transmission function network element determines the prime number 10 in the co-prime number array according to the numerical value a3, and obtains 4 based on the remainder calculation between 1424 and 10. The data transmission function network element sends data Q6 to the node T3.

[0160] The node T3 sends data Q8 to the data transmission function network element, the data Q8 includes the data Q7, the identification information of the data chain T and the value a4, the value a4=0.

[0161] The data transmission function network element determines that the data Q1 has been processed according to the value a4=0. The data transmission function network element sends the data Q7 to the data consumer.

[0162] The above is described by taking the value minus one as an example, but it is not limited to the way of determining the corresponding node based on the value plus one or the value minus one or the value minus two, etc. For example, the value a1=7, corresponding to the prime number 23, indicating the first node in the data chain, the value a2=8, corresponding to the prime number 29, indicating the second node in the data chain; the value a2=9, corresponding to the prime number 31, indicating the last node in the data chain.

[0163] Optionally, the business processing function network element and the data transmission function network element can interact the co-prime numbers in the selected co-prime number array. In this way, the business processing function network element can make the data transmission function network element determine the corresponding co-prime number through the above-mentioned value.

[0164] For example, the business processing function network element and the data transmission function network element interact the co-prime numbers in the selected co-prime number array, such as 10, 11, 13, 10, 11, 13 are arranged from low to high, such as {10, 11, 13}, the value a1 is greater than the value a2, such as the value a1=3, the data transmission function network element determines 13, the value a2=2, the data transmission function network element determines 11, the value a3=3, the data transmission function network element determines 1, the value a4=0, the data transmission function network element determines that the transmission is completed.

[0165] For another example, the business processing function network element and the data transmission function network element interact the co-prime numbers in the selected co-prime number array, such as 10, 11, 13, 10, 11, 13 are arranged from high to low, such as {13, 11, 10}, the value a1 is less than the value a2, such as the value a1=1, the data transmission function network element determines 13, the value a2=2, the data transmission function network element determines 11, the value a3=3, the data transmission function network element determines 10, the value a4=0, the data transmission function network element determines that the transmission is completed.

[0166] Optionally, the business processing function network element and the data transmission function network element can interact the number of co-prime numbers in the selected co-prime number array. In this way, the business processing function network element can make the data transmission function network element determine the corresponding co-prime number through the above-mentioned value.

[0167] For example, the number of the co-prime numbers in the co-prime number array selected by the service processing function network element and the data transmission function network element is 3, the co-prime numbers in the co-prime number array are arranged from low to high, such as {10, 11, 13, 17, 19, 23, 29, 31}, the value a1 is greater than the value a2, such as the value a1 = 3, the data transmission function network element determines 13, the value a2 = 2, the data transmission function network element determines 11, the value a3 = 1, the data transmission function network element determines 10, the value a4 = 0, and the data transmission function network element determines that the transmission is completed.

[0168] For another example, the number of the co-prime numbers in the co-prime number array selected by the service processing function network element and the data transmission function network element is 3, the co-prime numbers in the co-prime number array are arranged from high to low, such as {31, 29, 23, 19, 17, 13, 11, 10}, the value a1 is less than the value a2, such as the value a1 = 6, the data transmission function network element determines 13, the value a2 = 7, the data transmission function network element determines 11, the value a3 = 8, the data transmission function network element determines 10, the value a4 = 9, and the data transmission function network element determines that the transmission is completed.

[0169] In summary, the embodiments of the present application do not limit the manner in which the data transmission function network element determines the corresponding co-prime number in the co-prime number array according to the value.

[0170] In one possible embodiment, the value is related to or equal to the number of nodes in the data chain. For example, the number of nodes in a certain data chain is 2, and the value corresponding to the data stream is equal to 2. In this way, the data transmission function network element can determine the number of data transmission times according to the value.

[0171] In the embodiments of the present application, a plurality of data chains (each data chain can correspond to a data transmission function network element) can process the first data. For example, the data chain T and the data chain R process the first data, and after the data chain T processes the first data, the data chain R processes the data obtained by the data chain T processing the first data. In this way, the service processing function network element can indicate the data transmission path by indicating the identification information of the plurality of data chains and the corresponding plurality of values. Please refer to Table 2. The content described in Table 2 is only an example and is not the final limitation.

[0172] Table 2

[0173] As shown in Table 2:

[0174] The identification information S identifies a data chain S, and the data chain S includes a node U and a node R. The node U is a data transmission function network element 1, and the node R is a data transmission function network element 2. The identification information S and a value s1 are used to determine the node U. The node U manages a node T1 and a node T2. The node R manages a node R1 and a node R2. A value s2 obtained based on the value s1 corresponds to the node R.

[0175] The identification information A identifies a data chain T, and the data chain T includes the node T1 and the node T2. The node T1 and the node T2 are data processing function network elements. The identification information A and a value a1 are used to determine the node T1. A value a2 obtained based on the value a1 corresponds to the node T2.

[0176] The identification information B identifies a data chain R, and the data chain R includes the node R1 and the node R2. The node R1 and the node R2 are data processing function network elements. The identification information B and a value b1 are used to determine the node R1. A value b2 obtained based on the value b1 corresponds to the node R2.

[0177] The data transmission function network element can implement transmission of data according to the content shown in Table 2. For example:

[0178] The data transmission function network element sends data W2 to the node U according to the identification information S and the value s1. The data W2 includes: the data W1 (which can be the first data described above), the identification information S and the value s1 (s1 = 2), the identification information A and the value a1 (a1 = 2), and the identification information B and the value b1 (b1 = 2).

[0179] The node U determines the identification information A and the value a1 according to the value a1, and sends the data W2 to the node T1 according to the identification information A and the value a1.

[0180] The node T1 sends data W4 to the node U. The data W4 includes: data W3, the identification information S and the value s1, the identification information A and the value a2 (a2 = 1), and the identification information B and the value b1. The data W3 is data obtained by the node T1 processing the data W1. The node T1 determines the identification information A and the value a1 according to the value s1.

[0182] Node T2 sends data W6 to node U, data W6 includes: data W5, identification information S and value s1, identification information A and value a3 (a3=0), identification information B and value b1. Data W5 is data obtained by node T2 processing data W3. Node T2 determines identification information A and value a2 according to value s1.

[0183] Node U sends data W7 to the data transmission function network element, data W7 includes: data W5, identification information S and value s2 (s2=1), identification information A and value a3, identification information B and value b1.

[0185] The description of node R can refer to the description of node U, and will not be repeated here.

[0186] In addition, the service processing function network element can indicate multiple identification information and multiple corresponding values to the first device (see FIG. 5), or can indicate one identification information and one value to the first device, and send the corresponding identification information and value to the data transmission function network element (responsible for data transmission) corresponding to the other data chain (see FIG. 6).

[0187] In summary, the first device, the service processing function network element and the data transmission function network element can perform the following information interaction:

[0188] 1) The service processing function network element sends first information to the first device, the first information indicating at least one identification information and at least one corresponding value, each identification information in the at least one identification information identifying a data chain used for processing the first data, a first identification information (which can be the aforementioned identification information A or identification information S) in the at least one identification information identifying a first data chain (which can be the aforementioned data chain A or data chain S), and a first value (which can be the aforementioned value a1 or value s1) in the at least one value indicating a first node in the first data chain;

[0189] 2) The first device sends second data to the data transmission function network element, the second data including the first data, the at least one identification information and the at least one corresponding value;

[0190] 3) The data transmission function network element processes the second data according to the at least one identification information and the at least one corresponding value. For example, the data transmission function network element sends the second data to the first node in the first data chain according to the first identification information and the first value.

[0191] When the first information indicates one identity information, the description about the identity information can refer to the description of Table 1, and will not be repeated here.

[0192] When the first information indicates multiple identity information, the description about the multiple identity information can refer to the description of Table 2, and will not be repeated here.

[0193] Through the foregoing process, the data transmission function network element determines the transmission object of the first data according to the identity information and the value of the data chain, and the data transmission function network element does not need to perform the transmission of the first data according to the topic, which can support reducing the complexity of the data transmission process, for example, the data transmission function network element does not need to perform the publishing and subscribing of the topic and the like.

[0194] The communication method of the embodiments of the present application is further described below in combination with FIGS. 4 to 8.

[0195] II. Communication method

[0196] FIG. 4 is an interaction flow diagram of a communication method 400 of an embodiment of the present application. As shown in FIG. 4, the SSCF is an example of a service processing function network element, the DCP is an example of a data transmission function network element, the RAN node is an example of a first device, and the SDPF1 is an example of a data processing function network element. The method 400 takes an example in which the first information indicates a first identity information. The method 400 includes the following steps.

[0197] S401, the SSCF determines the first information.

[0198] For example, the SSCF receives request information from a data consumer, and the request information requests the SSCF to establish a transmission path for the transmission of the first data. The SSCF determines a first data chain according to the request information, and the first data chain includes the SDPF1 (and can also include other SDPFs), and the SDPF1 is used for processing the first data.

[0199] The first information includes the first identity information and a first value. The first identity information is used for identifying the first data chain, and the first value and the first identity information are used for indicating a first node in the first data chain, for example, for indicating the SDPF1. The nodes in the first data chain are used for processing data.

[0200] In the embodiments of the present application, the SSCF and the DCP can interact the identity information of each node in the first data chain and the coprime array. For example, the SSCF can determine the number of coprime numbers in the coprime array according to the number of nodes in the first data chain, and indicate the coprime numbers in the coprime array to the DCP. In this way, the DCP can determine the coprime number corresponding to the value in the coprime array according to the foregoing value.

[0201] S402, the SSCF sends first information to the RAN node. Correspondingly, the RAN node receives the first information.

[0202] Optionally, the first information can further include service identification of the first data and operation instruction information, etc. For example, the operation instruction information can include information such as the role of the RAN node (such as acting as a sending end of a sensing signal or a receiving end of a sensing signal, etc.), without limitation. The service identification of the first data is used to identify the service type or service identification corresponding to the first data, etc.

[0203] S403, the RAN node sends second data to the DCP. Correspondingly, the DCP receives the second data.

[0204] After the RAN node receives the first information, the RAN node performs a service and obtains the first data, and determines the second data according to the first data, the first identification information and the first value. The second data includes the first data, the first identification information and the first value. The first data is data that needs to be processed.

[0205] S404, the DCP sends the second data to the SDPF1 according to the first identification information and the first value. Correspondingly, the SDPF1 receives the second data.

[0206] For example, the DCP determines the identification information of the SDPF1 according to the first identification information and the first value and a coprime array, and sends the second data to the SDPF1 accordingly. The DCP has saved the address information of the SDPF1, or the identification information of the SDPF1 and the address information of the SDPF1 have an association or a corresponding relationship.

[0207] S405, the SDPF1 sends fourth data to the DCP. Correspondingly, the DCP receives the fourth data.

[0208] The fourth data includes the third data, the first identification information and a second value. The second value is determined according to the first value, for example, the second value is a value after the first value is reduced by one, such as the first value = 3 and the second value = 2. The third data is data obtained by the SDPF1 processing the first data.

[0209] Through the above process, the DCP determines a transmission path of the first data according to the first identification information and the first value, and transmits the first data according to the transmission path. The DCP does not need to transmit the first data according to a topic, and does not need to perform operations such as publishing and subscribing of the topic, so as to reduce the complexity of the data transmission process.

[0296] Optionally, the third information can also indicate the label information of each node in the first data chain, etc. The SCCF determines the corresponding node to process data according to the label information of each node. For example, the SCCF determines the processing order of the first data according to the label information of each SDPF in the SDPF1-SDPF7, for example, the SCCF determines that the SDPF3 processes the first data for the first time, the SCCF determines that the SDPF4 processes the first data for the second time, etc.

[0297] Through S803 and S804, the SSCF acquires the identification information of each node in the first data chain, and establishes the data chain according to the identification information of each node, and determines the identification information of the data chain accordingly.

[0298] Optionally, when the DCP updates the identification information of the node and / or the coprime array, the DCP can send the updated identification information of the node and / or the coprime array to the SSCF.
