It includes OSS (OperationSupportSystem, operation support system) and BSS (BusinessSupportSystem, business support system). The support system is the support system for the integration of telecom operators and the sharing of information resources. Among them, OSS includes all systems used to operate and monitor the network, such as reporting or billing systems; BSS design goals include customer relationship management (CRM, Customer Relationship Management), business supply chain management (SCM, Supply Chain Management) and business decision support systems ( DSS, Decision Support System).

At present, with the rapid development of telecommunications services and the increase in business complexity, the scale and number of interfaces of the supporting system are also rapidly expanding. How to realize the interface design between systems and modules, and ensure the reliability and fault tolerance of the interface has become a supporting system. Issues that must be considered during the construction process. At present, the support system is mainly oriented towards the realization of specific functions, independently developed according to a certain requirement, and the interfaces between the systems are different.

In the existing support system, the production system and the fault-tolerant system are constructed independently. In the event of an interface exception, the fault-tolerant system can only achieve system-level fault tolerance through inter-system switching. The interface layer of the existing support system lacks a unified fault-tolerant design, and can only achieve system-level fault-tolerant, rather than through the fault-tolerant design of the interface itself, the internal fault-tolerant is completed independently by each interface. When a single interface is abnormal, only the abnormal interface Perform fault tolerance without affecting the normal calls of other interfaces. In exceptional circumstances, interface-level business continuity cannot be achieved without system switching.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

As shown in FIG. 1 , the support system interface provided by the present invention includes: an external interface 1 , a production interface 2 , a fault-tolerant interface 3 , a data cache module 4 and a data correction module 5 . Among them, the external interface 1 constitutes the access layer for the external connection of the interface of the supporting system, the production interface 2 and the fault-tolerant interface 3 together constitute the fault-tolerant layer of the supporting system interface, the data cache module 4, the data correction module 5, and the The business logic processing module 6 for business processing and logic calling is included in the business logic layer in the supporting system. The business application system, background process and various peripheral systems in the telecommunications system together constitute the access layer of the access support system.

In the support system interface of the present invention:

The external interface 1 is used to receive the data sent by the access layer other than the support system, and forward the data sent by the access layer to the production interface 2 when the production interface 2 works normally, and when the call to the production interface 2 fails Downward forwarding to the fault-tolerant interface 3; the external interface 1 is also used to receive the data sent by the internal modules of the support system (such as the production interface 2), and forward it to the access layer. The purpose of external interface 1 is to realize the external interface definition of the support system, accept interface access requests initiated by the access layer or internal modules of the support system, and distribute external requests to production interface 2 or fault-tolerant interface 3 according to the internal interface status. The external interface 1 does not directly call the production interface 2 and the fault-tolerant interface 3. When the production interface 2 is normal, the production interface 2 is called first. If the production interface 2 fails, the fault-tolerant interface 3 is called to ensure that the production interface 2 is abnormal. Access continuity between external interface 1 and the access layer.

The production interface 2 is used to receive the data forwarded by the external interface 1, and call the business logic processing module 6 in the supporting system to process the data forwarded by the external interface 1; the production interface 2 is also used to transfer the processing result data of the business logic processing module 6 Send back to the external interface 1. The purpose of the production interface 2 is to accept the request forwarded by the external interface 1, and directly call the business logic processing module 6 to complete the relevant logic call and business processing, and return the processing result to the external interface 1.

The fault-tolerant interface 3 is used to receive the data forwarded by the external interface 1, and call the data cache module 4 to cache the data forwarded by the external interface 1. The purpose of the fault-tolerant interface 3 is: when the production interface 2 is abnormal, the fault-tolerant interface 3 accepts the access request forwarded by the external interface 1, and realizes request acceptance under abnormal conditions through data caching and data correction.

The external definition of fault-tolerant interface 3 is completely consistent with that of production interface 2, but the interface functions are completely different. Production interface 2 directly calls business logic module 6 to implement business processing, while fault-tolerant interface 3 is only used to cache external requests and then correct them through data Module 5 performs subsequent processing on the cached data and realizes synchronization with the production data generated by the business logic processing module 6 . One specific meaning of said synchronization is:

When the production interface 2 is normal, the external interface 1 will send the data at the first moment, the data at the second moment, the data at the third moment, the data at the fourth moment, the data at the fifth moment... ..Sequentially forward to the production interface 2, and the production interface 2 calls the business logic module 6 to process the data at the first moment, the data at the second moment, the data at the third moment, the data at the fourth moment, and the data at the fifth moment.. ....(Or the production interface 2 sequentially sends the data at the first moment, the data at the second moment, the data at the third moment, the data at the fourth moment, the data at the fifth moment... to the calling business over time logic module 6 for processing). In the above process, if there is a problem when the production interface 2 receives and forwards the data at the third time, the external interface 1 will send the data at the third time and the subsequent data at the fourth time, the data at the fifth time... Send to fault-tolerant interface 3 until production interface 2 returns to normal. When transferring from production interface 2 to fault-tolerant interface 3, there may be problems with the data forwarded from external interface 1 to production interface 2 and fault-tolerant interface 3. For example, at the third moment, data may be successfully transmitted to business logic processing module 6 through production interface 2, but It is sent to the fault-tolerant interface 3 and cached. At this point, the data correction module 5 will compare the data received and processed by the business logic processing module 6 from the production interface 2, and clear the cached data at the third moment, so as to avoid the business logic processing module 6 from repeatedly processing the third moment There are problems with the production data generated by the data.

The data caching module 4 is used for caching the data sent by the fault-tolerant interface 3 and sending the cached data to the data correction module 5 .

The data modification module 5 is used to call the business logic processing module 6 to process the data cached in the data cache module 4 , and to synchronize the data received and processed from the data cache 4 with the data received and processed from the production interface 2 . The purpose of the data correction module 5 is to perform subsequent processing on the cached data generated by the fault-tolerant interface 3. The data correction module 5 calls the business logic processing module 6 to process the cached data. If the call fails, wait for a certain period of time and then repeat the call until all The processing of cached data realizes the synchronization with the data received from the production interface 2 and ensures the consistency of the production data generated by the business logic processing module 6 .

The interface fault-tolerant method using the above-mentioned support system interface mainly includes the following processes:

Step A1: The external interface receives the data sent by the access layer other than the support system;

Step A2: When the production interface works normally, the external interface processes the data sent by the access layer through the production interface;

Step A3: In the case of failure to call the production interface, the external interface processes the data sent by the access layer through the fault-tolerant interface.

Step A21: the external interface forwards the data sent by the access layer to the production interface;

Step A22: The production interface receives the data forwarded by the external interface, and calls the business logic processing module in the supporting system to process the data.

Step A31: the external interface forwards the data sent by the access layer to the fault-tolerant interface;

Step A32: The fault-tolerant interface receives the data forwarded by the external interface, and calls the data cache module to cache the data;

Step A33: The data correction module calls the business logic processing module in the supporting system to process the data cached in the data cache module, and synchronizes the data received and processed from the data cache with the data received and processed from the production interface.
