Detailed Description
In 5G network communication based on eSBA, in technical specification TS29.510, when the service consumer finds that no instance information corresponding to the service provider is available, other instances are acquired by the network function search service of the NRF. When using the NRF discovery function, information of the service provider including discovery parameters such as: the service consumer can first send the discovery parameters of the service provider required by the service consumer to the NRF when the service consumer discovers the service provider through the NRF, the NRF can search in the registration information of the pre-stored service provider according to the discovery parameters and return the information of the target service provider corresponding to the discovery parameters, and the service consumer can communicate with the target service provider based on the information of the target service provider corresponding to the discovery parameters returned by the NRF.
In one or more embodiments of the present specification, before discovering service providers required by service consumers based on NRF, each service provider needs to register its own information in NRF, and the information includes protocol stack configuration information of each service provider. Specifically, the service provider may register information of a network function instance included in the service provider into the NRF through a network function registration service (NFRegisterservice) of a network function management service (nnrf_ NFManagement Service) of the NRF, wherein the information includes PDU protocol stack information of the network function instance. In one or more embodiments of the present disclosure, the PDU protocol stack information may be used as protocol mode information, and then a protocol mode (protocol mode) cell may be added in a network function configuration file (NFProfile) defined in TS29.510 and a network function service (NFService) cell of the network function configuration file, to represent PDU transmission protocol stack information of a current network function instance, where the protocol mode represents a configuration of a protocol stack.
Wherein the service provider comprises a plurality of network function instances, one network function instance comprises a plurality of network function services, and one network function service (nfServices) has a unique service instance identifier (servicelnstanceid). In one or more embodiments of the present specification, the service provider may include a network function instance and a network function service instance, that is, "nfInstanceId" and "nfserviceinstance", that is, in the present specification, "protocol stack modality information" corresponding to the service provider pre-registered in the NRF may include protocol stack modality information of the network function service instance and protocol stack modality information of the network function instance. In NRF, a protocol mode cell corresponding to protocol stack mode information of a network function instance may perform multi-protocol stack mode indication, and characterize a plurality of protocol mode composition types corresponding to nflnstanceid.
As shown in table 1, for the network function configuration file (NFProfile) defined in the present application based on TS29.510, a protocol mode type (protocol mode) cell is added to the network function configuration file.
TABLE 1
In one or more embodiments of the present disclosure, when a service consumer wants to make a service request for network discovery based on NRF, the service request sent by the service consumer to NRF includes at least protocol stack configuration information, that is, includes a protocol stack mode indication in indication information corresponding to the service request, where the protocol stack mode indication is shown in table 2. That is, the registration request of the service provider may carry a network function configuration file (NFProfile) of the service provider to be registered, where the network function configuration file includes a protocol mode (protocol mode) attribute. The query parameters of the NRF may include a target protocol mode (target-protocol-mode) attribute including protocol composition mode information (protocol mode info) that the service provider has registered in the NRF.
TABLE 2
For the purposes of making the objects, technical solutions and advantages of the present specification more apparent, the technical solutions of the present specification will be clearly and completely described below with reference to specific embodiments of the present specification and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present specification. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
The following describes in detail the technical solutions provided by the embodiments of the present specification with reference to the accompanying drawings.
Fig. 1 is a flow chart of a method of network communication provided in the present specification, where the method is applied to NRF, and specifically may include the following steps:
s100: and receiving a service request sent by a service consumer.
S102: and at least determining the target protocol stack composition information which is carried in the service request and matched with the service consumer.
Based on the above, the service consumer can discover the service through the network function of the NRF, and send the service provider discovery request carrying the protocol stack mode indication information query parameter, i.e. table 9, to the NRF. That is, the NRF may receive a service request sent by a service consumer, and at least determine target protocol stack configuration information that is carried in the service request and matches the service consumer.
The service request comprises a target protocol stack composition mode attribute, and the target protocol stack composition mode attribute comprises target protocol stack composition information for indicating the NRF to discover a target service provider based on the target protocol stack composition information. The target protocol stack configuration information matched with the service consumer refers to the protocol stack configuration information of the service provider required by the service consumer, or the protocol stack configuration supported by the service consumer and capable of communication.
S104: and determining the target service provider from the pre-stored protocol stack composition information of the service provider according to the target protocol stack composition information.
Further, since the information of each service provider is already registered in the NRF, the NRF can determine the target service provider from the pre-stored protocol stack configuration information of the service provider, based on the target protocol stack configuration information. In one or more embodiments of the present specification, the NRF may further determine other information in the service request, such as a service type required by the service consumer, a service identifier of a service provider required by the service consumer, or the like, that is, the information carried in the service request by which the service consumer sends the precious NRF may further include a service type required by the service consumer, or the like, specifically what information may be carried in the service request, which is not specifically limited in the present specification. The NRF may determine the target service provider from the pre-stored protocol stack configuration information of the service provider according to the determined target protocol stack configuration information and other information such as the service type.
S106: and sending the address information of the target service provider to the service consumer so that the service consumer can perform service communication with the target service provider based on the address information.
Finally, the NRF may transmit address information of the target service provider to the service consumer so that the service consumer may perform service communication with the target service provider based on the address information of the target service provider. In one or more embodiments of the present disclosure, the NRF may further send, to the service consumer, other information of the discovered target service provider, such as a service identifier, a service type, etc. of the target service provider, and specifically, the present disclosure is not limited, so that the service consumer may select, based on the received information of the service provider, to obtain a final service provider, and perform service communication with the final service provider based on an address of the final service provider.
Further, in one or more embodiments of the present specification, the service provider includes a network function service instance and a network function instance, and the NRF may determine the target network function service instance and/or the target network function instance from the pre-stored protocol stack configuration information of the network function service instance and the protocol stack configuration information of the network function instance according to the target protocol stack configuration information. The service consumer may select, in the received target network function service instance and/or target network function instance, according to a preset rule, to obtain a final target instance. It should be noted that, in the NRF-returned target network function service instance and/or the target network function instance, when it is determined that both the target network function service instance and the target network function instance exist, the service consumer preferentially selects the final target instance from the target network function service instances.
Briefly, in one or more embodiments of the present specification, first, a service provider carried on an eSBA with a 5G service architecture may register, in advance, respective protocol configuration mode information into an NRF through a registration service of a network function management service of the NRF, where the registration request carries a network function configuration file of the service provider to be registered, where the network function configuration file includes a protocol mode attribute. The protocol mode attribute can be added to the network function service in the network function configuration file and the network function service contained in the network function service list.
Then when the service consumer carried on the 5G service architecture eSBA needs the service provider to process the service request through the corresponding protocol mode, the service request can be searched through the enhanced network function search service of the NRF, and the search request can carry heterogeneous redundancy indication query parameters. The query parameters of the NRF include a target protocol mode attribute, and the target protocol mode attribute includes protocol configuration mode information that a service provider has registered in the NRF.
The NRF may then return registration information of the service provider according to the service request of the service consumer. The service request includes a target protocol stack composition mode attribute, and the target protocol composition mode attribute includes target protocol stack composition information, so that the NRF can search and return the service provider in the network function configuration file registered in the NRF according to the protocol stack composition mode information included in the new target protocol stack composition mode attribute in the query request.
And finally, the service consumer carried on the 5G service architecture eSBA can receive a target service provider with a target protocol stack constituting mode returned by the NRF, and can select a final target instance from the target service provider based on a preset rule so as to communicate the final target instance (service provider instance) with the target protocol stack constituting mode, namely, initiate a service flow.
Based on the above network communication method provided in the present specification shown in fig. 1, the network storage function network element may receive a service request sent by a service consumer, and at least determine target protocol stack configuration information that is carried in the service request and matched with the service consumer. And then determining the target service provider from the pre-stored protocol stack composition information of the service provider according to the target protocol stack composition information. Finally, address information of the target service provider can be sent to the service consumer so that the service consumer can conduct service communication with the target service provider based on the address information. Because the service request sent by the service consumer, namely the network function discovery request, carries the target protocol stack composition information, and the network storage function network element has the pre-stored protocol stack composition information of the service provider, the protocol stack composition information of the service provider discovered by the network storage function network element and returned to the service consumer can be matched with the service consumer, so that the condition that smooth communication cannot be realized due to different protocol stack compositions can not occur when the service consumer communicates with the service provider, and the stability of network communication is improved.
Fig. 2 is a flow chart of a method of network communication provided in the present specification, where the method is applied to a service consumer, and may specifically include the following steps:
s200: transmitting a service request to a network storage function network element, so that the network storage function network element determines a target service provider from protocol stack composition information of the pre-stored service provider based on the service request, and returns address information of the target service provider to the service consumer; and the service request carries the target protocol stack composition information matched with the service consumer.
S202: and receiving the address information of the target service provider returned by the network storage function network element.
S204: and carrying out service communication with the target service provider based on the address information.
The service consumer may send a service request to the NRF, the NRF may determine a target service provider from the pre-stored protocol stack configuration information of the service provider based on the service request, and the NRF may return address information of the target service provider to the service consumer, where the service request carries the target protocol stack configuration information matched with the service consumer. The service consumer may receive the address information of the target service provider returned by the NRF, and may also receive other information of the target service provider returned by the NRF. Also, in one or more embodiments of the present description, the target service provider may be plural. And the service consumer can then conduct service communication with the final target service provider based on the address information of the target service provider.
In one or more embodiments of the present specification, the target protocol mode attribute may include query condition information of a network function configuration file of protocol mode registration information registered by the service provider in the NRF, and may further include query condition information of a network function configuration file of protocol mode registration information included in a network function instance (nflnstanceid) and/or a network function service instance (nfServiceInstanceId) of a corresponding network function type (NFType) registered by the service provider in the NRF.
In one or more embodiments of the present description, the service provider includes a network function service instance and a network function instance, and the service consumer may receive address information of the target network function instance and/or address information of the target network function service instance returned by the network storage function network element. And further, a final target instance can be selected from the received target network function instances and/or target network function service instances according to preset rules.
As shown in fig. 5, a network function discovery procedure is provided in the present specification. The service consumer is nf_a and the service provider is nf_b. When the service consumer initiates the network function discovery service (nnrf_ NFDiscovery Service) with the attribute "target-protocol-module= protocolModalityInfo (K)" in table 2, the NRF may return corresponding network function instance configuration files, i.e. NFProfile1 and NFProfile2 in fig. 5, according to the network function instance parameter registration information of nf_b, i.e. the pre-stored information of the service provider, where the configuration files may include one or more network function instance information, and the returned instances in fig. 5 include NF1 and NF4. It can be seen that NF1 is a network function instance, i.e., nfInstanceId, NF is a network function service instance, i.e., serviceInstanceId.
As shown in table 3, for the protocol mode information cell structure provided in the present specification, the data structure cell "protocol mode information (protocol mode info)" of the protocol mode cells may include layer 6 protocol indication information (L1 to L6).

Wherein L1 represents a physical layer, and the carried protocol mode information is shown in table 4, and may include Twisted pair mode (COAX), fiber Cable mode (COAX), and wireless mode (wireless).

L2 represents a link layer, and the carried protocol mode information is shown in table 5, and may include an ethernet (ethernet) mode and a point-to-point protocol (Point to Point Protocol, PPP).

TABLE 8
L6 represents an application layer, and the carried protocol mode information is shown in table 9, and may include HTTP mode, GTP and packet forwarding protocol (PacketForwardingControlProtocol, PFCP) mode.
TABLE 9
When a service consumer triggers a service request, and meanwhile, because of the requirement on a network function PDU transmission protocol mode, a service provider is required to match the protocol stack mode, the service consumer does not have available examples or protocol stack mode information of the available service provider in a cache at the moment, and a query request for example information of the service provider with a corresponding protocol stack mode is required to be initiated through NRF. When a first layer of protocol mode (protocol mode) of a network function instance identified by "nflnstageid" in "NFProfile" of the same network function and a second layer of protocol mode of a network function service instance identified by "ServiceInstanceId" carried on "nfinstanceby" of the network function instance each contain matched protocol mode information ("protocol mode info"), both the corresponding network function instance and the corresponding network function service instance need to be returned.
In one or more embodiments of the present disclosure, a target protocol mode (target-protocol-mode) attribute may be added to a query parameter for a network function discovery service (nnrf_nfdiscovery service), where the attribute includes query condition information for a network function configuration file of a "network function service instance" or a "network function instance" to which "protocol mode information" belongs, where the "network function state" or "network function service state" is registered in the NRF by a service provider.
Based on the method of network communication shown in fig. 1, the embodiment of the present disclosure further provides a schematic diagram of an apparatus for network communication, as shown in fig. 3.

Based on the method of network communication described in fig. 2, the embodiment of the present disclosure further provides a schematic diagram of an apparatus for network communication, as shown in fig. 4.
Fig. 4 is a schematic diagram of an apparatus for network communication according to an embodiment of the present disclosure, where the apparatus is located in a service consumer, and the apparatus includes:
A sending module 400, configured to send a service request to a network storage function network element, so that the network storage function network element determines a target service provider from pre-stored protocol stack configuration information of the service provider based on the service request, and returns address information of the target service provider to the service consumer; wherein, the service request carries the target protocol stack composition information matched with the service consumer;

The embodiments of the present specification also provide a computer-readable storage medium storing a computer program that can be used to perform the method of network communication described above.
Based on the above-mentioned network communication method, the embodiment of the present disclosure further proposes a schematic structural diagram of the electronic device shown in fig. 6. At the hardware level, as in fig. 6, the electronic device includes a processor, an internal bus, a network interface, a memory, and a non-volatile storage, although it may include hardware required for other services. The processor reads the corresponding computer program from the nonvolatile memory into the memory and then runs the computer program to realize the network communication method.
Of course, other implementations, such as logic devices or combinations of hardware and software, are not excluded from the present description, that is, the execution subject of the following processing flows is not limited to each logic unit, but may be hardware or logic devices.
In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but not just one of the hdds, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.
The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function. One typical implementation is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being functionally divided into various units, respectively. Of course, the functions of each element may be implemented in one or more software and/or hardware elements when implemented in the present specification.

These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
In one typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.
The memory may include volatile memory in a computer-readable medium, random Access Memory (RAM) and/or nonvolatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of computer-readable media.

Computer-readable media, as defined herein, does not include transitory computer-readable media (transmission media), such as modulated data signals and carrier waves.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.
