To configure radio base stations is a complex and time demanding task. Therefore, Ericsson Radio Systems AB (ERA) in Linköping wanted to investigate if workflow technology could be used in their Operations and Support System (OSS) to facilitate the configuration work. The following objectives were stated for the investigation:
During the work, a number of limitations were discovered in TeamWARE Flows supplied Viewer client. Due to this, we decided to develop a new client using the provided API. Three design suggestions were considered and the one choosen was based on CORBA. Although TeamWARE Flow doesnt fully support WfMCs workflow standards we managed to develop solutions for data transfer and invocation of applications.
Our main conclusion is that workflow can be applied to the configuration process, but it will be much easier when future, standard conforming workflow tools arrive. In the meantime, we recommend Ericsson to adapt the OSS to support workflow standards according to our given proposals.
