Software integration is already a big problem that operators have to face. The number of interoperability issues that are not compatible with the application interfaces provided by the number of independent software companies are making operators' focus, which is why Java technology is based. OSS (OSS / J) is getting more and more important. The original intention of OSS / J is from the company's J2EE (Java 2 Enterprise Edition) to resolve application interface compatibility issues, and Java technology is also the same. SUN Microsystems' philippe lalande pointed out that "Java's fundamental idea is compatibility, The biggest challenge in the OSS field is to face a large number of applications incompatible issues. "September 2000, Ericsson, NEC, Nokia, Nortel Network, Sun and Telcordia jointly created an OSS / J API, ready to 3G wireless communication Activation and business quality solutions for business, as well as the application programming interface required for fault detection. German Telecom's T-Systems is an example of the application of OSS / J, which uses German OSS Provider IP Value's OSS / J-based business plan and Service Creation Factory platform, using standard APIs to provide processes. Automatic processing, greatly reduced maintenance and operating costs. Most OSS system suppliers also admit that the OSS / J interface is becoming in fact industry standards, developers and operators have now downloaded more than 25,000 of the above APIs for free from OSS / J website for free. Moreover, with the US local Bell's deployment of OSS, OSS / J develops seems to be unlimited. Although the current OSS / J cannot be a secret weapon that leads to system suppliers, Java Community Process JCP) The promotion of the organization is obvious. In addition, OSS / J can greatly simplify the process of enterprise merger is also worthy of attention. A large system supplier adopts an open OSS / J standard, which is easier to integrate independent programs into its products, so you can accelerate the pace of integration. Metasolv, M &LV, M & A, Nortel Network, last year, may experience the deepest in this regard, the Nortel Network is one of the members of JCP. After joining OSS / J for a few months, I acquired a service activity (Service Activation). Architel, and Metasolv, which acquired Nortel Network OSS department is also one of OSS / J initial founders. Since the three are the leading providers of OSS / J applications, Metasolv may be a company that integrates pain after the integration of enterprises in OSS. Metasolv's instance may prompt to turn to OSS / J, which may also alleviate the worry of operators mergers to integrate OSS system, although the former is not synonymous with the integration of large operators OSS systems, but cannot Deny, OSS / J open-ended interfaces will alleviate the pain of mergers. As the key OSS / J API development is completed, for telecom operators, it is time to use this advanced technology as soon as possible, so that the industry is pleased, and the era of various mutually incompatible and mutual conflict problems will also be This is gradually moving.
