To create a mechanism to discover management services efficiently and correctly becomes necessary to implement management services' openness in next generation network. Since management service is different to telecommunication service in features, a new method is presented to resolve its registration and discovery in publication. Unified Openness Service Identification-UOSI can search management services in a faster, safer, more administrable and network resources saved way by establishing services' indexes. UOSI includes universal description, discovery and integration-UDDI technology. The paper brings forward Shared Management Service Data Center-SMSD and Management Service Identification-MSID conceptions to ensure that the method works. MSID definition, creation, searching tree and extension rule are described at the same time. UOSI adds MSID in management services' publication to improve search Precision and improve search time.
