Nokia Siemens Networks Chief Operating Officer Mika Vehvilainen said Tuesday the company aims to increase its share of the third-generation mobile phone equipment bought by China's telecommunications carriers.

Nokia Siemens Networks is unsatisfied with its current market share in TD-SCDMA equipment purchases, Vehvilainen said. TD-SCDMA is the homegrown 3G network developed by China Mobile Communications Corp., the parent of China Mobile Ltd. (CHL).

Nokia Siemens Networks is a joint venture between Nokia Corp. (NOK) of Finland and Germany's Siemens AG (SI).
