Bellevue-based Vallent, which helps wireless carriers manage and monitor the performance of their networks, said today at 3GSM that its acquisition with IBM is complete.

IBM announced in November that it agreed to acquire Vallent, a privately held software company with more than 400 employees.

IBM said today that Vallent's operations will be integrated into the IBM Software Group's Tivoli Software unit. With Vallent, IBM can now offer services for wireline, wireless, IP, and IT infrastructure to help clients manage services from the server to the handset.

Vallent will also help IBM offer services to new opportunities, such as fixed-mobile convergence and IP Multimedia Subsystem (IMS) deployments.
