Network Capability Exposure System Scheme And Test Method Based On Multi-domain Communication Capability

With the rapid development of smartphones and mobile Internet,there has been a tremendous change in the demand for user communications.Telecom operators have gradually the trend of becoming the pipeline.In order to avoid pipelining,operators have proposed the concept of network capability exposure.However,the existing network capability exposure system only expose some basic capabilities such as voice service and message service,and there is not a good solution in network capability exposure scheme and APIs.In addition,since network capability exposure are similar to Web services,test scheme is different from traditional communications equipment test scheme.So it is an important issue that researching test method of the network capability exposure system.In view of the above problems,this paper studies the multi-domain network capability exposure system based on the work carried out at China Mobile Research Institute.First of all,according to China Mobile multi-domain network capability system architecture,the existing net element of audio&video,message,pipeline domain in core network were studied,the capability platform scheme is presented.According to the existing business domain communication ability,the design of RESTful API scheme and its invocation process is presented.Secondly,according to the existing online charging scheme,a network capacity exposure API online charging scheme is designed,and the invocation process based on session and event is designed.This paper analyzed the applicability of some test method in multi-domain network capacity exposure system,and using the grey box testing method based on UML activity diagram to design test scheme,and according to the division of the business domain to explain the test case.Multi-domain network capacity exposure system testing proves that this method can increase the coverage of invocation path.
