Ericsson has finalized a number of major GSM expansion contracts with China Mobile which collectively worth more than USD 550 million, said the company in a statement. The contracts cover expansion projects in 17 regions and further strengthen Ericsson's position as the leading mobile communications supplier in the Chinese market. Under the contracts, Ericsson will provide China Mobile with core and radio networks, along with related technical support and services. Ericsson will also deploy its Mobile Softswitch Solution. Ericsson's cooperation with China's mobile communications industry dates back to 1987, when Ericsson supported China in deploying the country's first analog mobile communications systems in Guangdong and Hebei provinces.
