The emergence of the Mobile Internet has focused special attention on the service network, which is where network operators can expect to develop, launch and bill for new services in a streamlined way, tapping valuable new sources of revenue. Service networks are complex multi-vendor, multi-technology environments defined by many different interfaces and standards.
