Ericsson tops the wireless core market, the report says

C114 Beijing Time June 15 Morning News (SHANGMU) Exact Ventures's latest report shows that as mobile data and signaling flows continue to grow, the global Wireless Packet Core network market includes EPC (Group Core Evolution), which grew 50% in the first quarter of 2011.　　Smartphone penetration and mobile data traffic are expected to continue to rise in the foreseeable future, driving the wireless packet core market to double-digit growth in 2011.　　In the first quarter of 2011, Ericsson stayed ahead with a 26% market share. With its performance in Latin America, Huawei became the second-largest provider of wireless packet core networks, earning slightly less than Ericsson. Cisco is ranked third in the 18% market share of North American sales due to strong PDSN (Packet Business data node).　　Nokia Siemens shot into the top four this quarter. The PCRF (Policy and Billing rules feature) market is currently dominant in the EPC market as operators have been deploying PCRF devices to support wcdma/hspa+ data Services.　　"said Greg Collins, founder and chief analyst of Exact Ventures. "Other EPC components are currently deployed to support the LTE business." PCRF is a key component of wireless packet core network, which enables operators to differentiate network traffic. He adds that PCRF is increasingly important to operators because of the need to differentiate between revenue-generating uses and businesses that require a distinction between network traffic.
