Tekelec which delivers services including network signalling, mobile data management and mobile subscription services, has been purchased by Oracle, as the IT giant continues to expand its communications portfolio.

The deal is expected to be finalised in the first half of 2013, with Oracle looking to capitalise on recent acquisitions and the increasing use of mobile services.

The deal will also bring Tekelec’s customers under the roof of Oracle, including main telecoms providers such as T-Mobile, AT&T, Verizon and Orange.

Oracle CEO, Larry Ellison, described how the company was looking to become: “one of the most strategic suppliers to telcos overall, which involves broadening our footprint of what we supply them”.
