CSL is a subsidiary of Australia’s Telstra Corporation and is the biggest mobile operator in Hong Kong. In March 2008, CSL contracted ZTE to evolve its existing mobile network into a new all-IP mobile network. To reduce the high Operating Expense (OPEX) of network operation and maintenance, CSL sought an Integrated Network Management System (INMS) to consolidate alarms from various network segments, and to improve network operation and maintenance efficiency. ZTE provided CSL with an integrated network solution based on Software Defined Radio (SDR) soft base stations. The SDR solution supports upgrade to High Speed Downlink Packet Access (HSDPA+) and enables a smooth transition to a Long Term Evolution (LTE) network.

Ethiopian Telecommunications Corporation (ETC) has acquired a patchwork of systems and processes that makes it difficult to cost- efficiently troubleshoot network faults , launch new services quickly, and track and tune the performance of services once delivered . This patchwork also results in increased operational and capital expenditures , so there is an obvious need for ETC to improve and evolve the network and service management environment. Evolving ETC s network and service management systems and processes shall be done in a well organized phased approach . ZTE is the first choice for ETC to assume this challenging responsibility and provide the National Network Operation Center (NNOC) solution .
