Oracle is buying Portal Software for $220m (£129m) to offer its media company customers an easier way to bill their subscribers.
Oracle said Portal Software's billing and revenue management software will complement its existing applications sold to media companies.
Oracle president Charles Phillips said, “We supply technology and applications to over 90% of communications companies worldwide, and billing is a logical and complementary addition for those customers.”
The acquisition follows Oracle’s other buys of suppliers serving niche markets. Oracle has bought retail industry supplier Retek and financial services market specialist iFlex in the past year.
Portal Software supplies packaged applications that can be used by media companies to bill for multiple services, such as broadband, standard and IP-based voice calls, and wireless connectivity.
Portal Software employees will now form the basis of a new communications business unit within the Oracle group, said the company.
