Detailed Description
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 service execution method based on resource binding provided in the present specification, which includes the following steps:
s101: the method comprises the steps that a first communication terminal is used as a service consumption terminal, a first service request carrying a first heterogeneous resource binding hypertext transfer protocol (HTTP) header is sent to a designated function instance in a second communication terminal which is used as a service providing terminal, and the second communication terminal executes the first service request through the designated function instance.
Network Function virtualization (NFV, network Function Virtualization) decouples the relationship of software and hardware strong binding in traditional physical devices by applying standardized Network Functions (NF) to unified hardware. Through a plurality of network function instances (Network Function Instance) virtually implemented on the unified hardware device, a plurality of heterogeneous network function instance groups (Network Function Set) with different network functions, which are formed according to the network functions and logic/codes corresponding to the operating system kernel, are loaded on each of the plurality of network function instances, and then corresponding service requests are executed through the function instances in the instance groups. In practical applications, heterogeneous architectures may be built at the NF Instance (NF Instance) level, NF Service Instance (NF Service Instance) level, NF group (NF Set) level, and NF Service group (NF Service Set) level.
Based on this, the present specification provides a service execution method based on an enhanced service architecture, which is based on multiple sets of operating systems virtualized on a unified hardware device, and loads virtual network function and application function interfaces (APIs, application Program Interface) with the same network function and application function interfaces on different operating systems, and the same network function instance group (Network Function Instance Set) is formed by multiple network function instances (NF, network Function Instance) compiled into different operation logics according to the kernel of the operating system, and provides high-reliability system function execution guarantee by means of a newly added resource binding HTTP header definition for indicating heterogeneous implementation service processing resources when each communication end is used as a service providing end, and the resource binding HTTP header definition is respectively carried in service requests of service consumers and service replies of service providers.
In a communication system, a Service Provider (SP) represents an operator of a network Service, and a Service Provider corresponding to the Service Provider provides network functions corresponding to different network services to a user, and executes corresponding services through corresponding network functions after receiving a Service request.
The service consumer ((Service Consumers, SC) represents a program for accessing a service according to a service interface description, and a user transmits a service request to a service provider through its corresponding service consumer to execute a corresponding service through a network function corresponding to the service provider.
In this specification, the above example may be an actual program set corresponding to a network function, and the network function provided by the service provider corresponding to the service provider may include: authentication server functions, access and mobility management functions, data networks, such as operator services, internet access or third party services, unstructured data storage functions, network opening functions, network repository functions, network slice selection functions, control policy functions, session management functions, unified data management, (wireless) access networks, service communication agents, wired access gateway functions, etc., which are not exemplified one by one in this specification.
When the first communication terminal is used as a service consumption terminal and the second communication terminal is used as a service providing terminal, the first service request can be sent to a designated function instance in the second communication terminal through the function instance of the first communication terminal, and the designated function instance is used for providing a network function corresponding to the first service request. The service request carries a first heterogeneous resource binding hypertext transfer protocol (Hypertext Transfer Protocol, HTTP) header.
Specifically, in practical application, each network element function of the 5G eSBA service architecture performs service communication connection through a service-based interface (SBI, service Based Interface), where the SBI uses hypertext transfer protocol/2 (HTTP/2) and uses transport layer security (Transmission Layer Security) to ensure communication security between network functions that constitute both parties of service communication. The HTTP/2 message is composed of an HTTP Header (Header) and JavaScript Object Notation (JSON, javaScript Object notification) file. The HTTP header contains a request header sent by the service consumer and a response header replied by the service provider. The basic information of the service request transmitting end is described by HTTP Standard Headers (Standard Headers) and optional Headers (Custom Headers).
In this specification, a Heterogeneous resource Binding HTTP header (3 gpp-Sbi-generic-Binding) may be added to indicate each communication end as a service providing end, and carried in a service request of a service consumer and a service reply of a service provider, so as to provide a high-reliability system function execution guarantee.
When the first communication terminal is used as a service consumption terminal and the second communication terminal is used as a service providing terminal, the first heterogeneous resource binding HTTP header carried by the first service request is used for indicating the communication address of each heterogeneous target function instance executing the second service request to the second communication terminal when the second communication terminal is used as a service consumer to send the second service request, and at least part of the heterogeneous target function instances are compiled by different operating systems, so that the isomerism of each heterogeneous target function instance is realized.
In this specification, the above-mentioned encoding object of the heterogeneous resource binding HTTP header may include a binding level (binding level), a parameter (parameter), a recovery time (recovery time), a notification receiver (notify-receiver), a resource group/session context parameter (group of resource/session context), and the like.
The second communication terminal is used as a service providing terminal, and after receiving a first service request carrying a first heterogeneous resource binding HTTP header, the second communication terminal can execute the service request through the specified function instance and obtain an execution result corresponding to the service request.
And then the second communication end can carry the execution result and the second heterogeneous resource binding HTTP header corresponding to the second communication end in the request reply message, and return the request reply message to the first communication end. The second heterogeneous resource binding HTTP header is configured to indicate, to the first communication end, a communication address of each heterogeneous target function instance that executes a subsequent service request, in a case that the first communication end cannot receive a valid service request processing reply.
Specifically, when the first communication end is converted into the service end again and the second communication end is converted into the service providing end, if the previous designated function instance in the second communication end cannot execute the subsequent service request sent by the first communication end or cannot send an effective service request processing reply, the first communication end can analyze the second heterogeneous resource binding HTTP header at this time, determine each standby heterogeneous function instance in the second communication end, send the service request to each heterogeneous function instance, and judge the execution result of each heterogeneous function instance.
S102: when the first communication end is converted into a service providing end and the second communication end is converted into a service consuming end, receiving a second service request sent by the second communication end to each heterogeneous target function instance in the first communication end, wherein each heterogeneous target function instance is obtained after the second communication end analyzes the first heterogeneous resource binding HTTP header.
S103: and executing the second service request through the heterogeneous target function examples to determine an execution result corresponding to each heterogeneous target function example.
When the first communication end is converted into the service providing end and the second communication end is converted into the service consuming end due to the requirement of the subsequent service flow, the second communication end can analyze the first heterogeneous resource binding HTTP header carried by the first service request, so that each heterogeneous target function instance in the first communication end is determined.
Specifically, the second communication end may send the first heterogeneous resource binding HTTP carried by the first service request to a preset network storage function (Network Repository Function, NRF) end, query, by using the NRF end, a communication address of each heterogeneous target function instance in the first communication end pointed by the first heterogeneous resource binding HTTP head, and return the communication address to the second communication end.
And then the second communication terminal can send the second service request to each heterogeneous target function instance in the first communication terminal according to the communication address of each heterogeneous target function instance.
In this specification, there may be various manners in which the second communication end sends the second service request to the first communication end as the service consumption end, for example, the second communication end (the service consumption end at this time) may send the service request to all target instances in the first communication end (the service providing end at this time) at the same time, and broadcast, multicast, and unicast modes are adopted.
For another example, the second communication end may sequentially select and send the service request to a part of heterogeneous target function instances according to a certain algorithm, and terminate sending the service request to the other target service instances after the received service execution result can reach the effective decision result.
Of course, the second communication end may send multiple service requests to only a single heterogeneous target function instance for a period of time, and make a decision by collecting request reply information in a certain period of time.
Before each heterogeneous target function instance executes the service request, the server can load each corresponding operating system kernel, and then compile the corresponding heterogeneous target function instance through each operating system kernel, so that in practical application, the server can execute a second service request according to each compiled logic code.
S104: and determining a target execution result corresponding to the second service request according to the execution result corresponding to each heterogeneous target function instance, and returning the target execution result to the second communication terminal.
The first communication end can determine the target execution result corresponding to the second service request according to the execution result corresponding to each heterogeneous target function instance receiving the second service request, for example, the first communication end can make minority compliance majority decision on the result of each target communication instance, and take the execution result with the largest number as the target execution result and return to the second client.
Of course, the first communication end may also return all the execution results to the second client, where the second client determines each execution result and selects the execution result with the largest number as the target execution result.
For ease of understanding, the present disclosure provides a communication process schematic based on heterogeneous resource binding HTTP header, as shown in fig. 2.
Fig. 2 is a schematic diagram of a communication process based on a heterogeneous resource binding HTTP header provided in the present specification.
The nf_a and nf_b are two different communication ends, when nf_a is converted into a service providing end and nf_b is converted into a service consuming end, nf_b searches a Heterogeneous instance group of service resource Binding designated by nf_a through a network function discovery service of NRF according to a Heterogeneous resource Binding HTTP header carried by nf_a in a service request through 3 gpp-Sbi-heterogenic-Binding, determines each Heterogeneous target function instance and sends the service request, so that even if instance 1 and instance 2 in nf_a fail, a final target execution result can be determined according to other Heterogeneous instances (instance 3, instance 4 and instance 5).
Further, when the first communication end is converted into the service consumption end and the second communication end is converted into the service providing end, the first communication end may determine and send each heterogeneous target function instance in the second communication end according to the second heterogeneous resource binding HTTP header carried in the request reply message sent by the previous second communication end, and a method for determining each heterogeneous target function instance in the second communication end and a method for determining a target execution result are the same as the above-mentioned methods, which are not repeated in the present specification.
In the foregoing, a service execution method based on resource binding provided in the present specification is described from the perspective of the first communication end, and in order to facilitate understanding, a service execution method based on resource binding provided in the present specification is described from the perspective of the second communication end, as shown in fig. 3.
Fig. 3 is a flow chart of a service execution method based on resource binding provided in the present specification, which includes the following steps:
s301: the second communication terminal is used as a service providing terminal and receives a first service request which is sent to the appointed function instance by the first communication terminal and carries a first heterogeneous resource binding HTTP header.
S302: executing the first service request through the designated function instance.
S303: when the second communication end is converted into a service consumption end, the first communication end is converted into a service providing end, and the first heterogeneous resource binding HTTP header is analyzed to obtain each heterogeneous target function instance in the first communication end.
S304: and sending a second service request to each heterogeneous target function instance in the first communication terminal so that the first communication terminal determines an execution result corresponding to each heterogeneous target function instance, and according to the execution result corresponding to each heterogeneous target function instance, determining a target execution result corresponding to the second service request and returning to the second communication terminal.
Further, the present disclosure further provides a schematic diagram of a communication reliability enhancing method based on resource binding, as shown in fig. 4.
Fig. 4 is a schematic diagram of a communication reliability enhancing method based on resource binding provided in the present specification.
When nf_a is a service consumer and nf_b is a service provider, nf_a may send a first service request carrying a first heterogeneous resource binding HTTP header to nf_b, query, by using NRF, a network address (the designated function instance may be multiple or one) of the designated function instance in nf_b, send the service request to the designated function instance, and after the designated function instance in nf_b executes the service request, may return request reply information of an execution result to nf_a, where the request reply information may carry a second heterogeneous resource binding HTTP header corresponding to nf_b.
When nf_a is converted into a service providing end and nf_b is converted into a service consuming end, nf_b can bind the HTTP header according to the first heterogeneous resource, query each heterogeneous target function instance in nf_a through the NRF end, send a service request to each heterogeneous target function instance in nf_a, and nf_a can make minority-compliance majority decision according to the execution result corresponding to each heterogeneous target function instance, so as to return request reply information of the target execution result to nf_b.
According to the method, when the first communication terminal is used as the service consumption terminal to send the service request to the second communication terminal, the heterogeneous resource binding HTTP head for pointing to the heterogeneous target function instance is sent to the second communication terminal at the same time, so that when the second communication terminal is used as the server consumption terminal and the first communication terminal is used as the service providing terminal, a plurality of heterogeneous target function instances can be determined according to the heterogeneous resource binding HTTP head, a final target execution result can be accurately determined through the execution results of the heterogeneous target function instances, the accuracy and the reliability of the final target execution result are guaranteed, and the safety of a communication system is further guaranteed.

Fig. 6 is a schematic diagram of a service execution device based on resource binding provided in the present specification, including:
a receiving module 601, configured to receive, by using a second communication terminal as a service providing terminal, a first service request that is sent by a first communication terminal as a service consuming terminal to a specified function instance and carries a first heterogeneous resource binding HTTP header;
an execution module 602, configured to execute the first service request through the specified function instance;

The present specification also provides a computer readable storage medium storing a computer program operable to perform a resource binding-based service execution method as provided in fig. 1 above.
The present specification also provides a schematic structural diagram of an electronic device corresponding to fig. 1 or fig. 2 shown in fig. 7. At the hardware level, the electronic device includes a processor, an internal bus, a network interface, a memory, and a non-volatile storage, as described in fig. 7, although other hardware required by other services may be included. The processor reads the corresponding computer program from the nonvolatile memory into the memory and then runs the computer program to implement a service execution method based on resource binding as described in fig. 1 or fig. 2. 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.
Improvements to one technology can clearly distinguish between improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) and 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.
