A new report by Peter Mottishaw (pictured), Principal Analyst, Analysys Mason finds that "The service delivery platform (SDP) market generated USD3.63 billion in revenue in 2010, up 7% from USD3.38 billion in 2009 [here]. Growth was lower than expected because of delays to real-time charging projects in some emerging markets and to investments in mobile device management, caused by the slow growth in related services for communications service providers (CSPs)".
