SigEngine—the Expertise of Communication Network Intelligence

    Liangjiang Communications System Inc., founded in February 2002, focuses on innovation and revolution in signalling processing and communication control field.

    Liangjiang is a pilot enterprise in patent in Shanghai, got certificate of ISO9001 and received SEI CMM level3 software rating in 2005. At initial stage Liangjiang embarked on the development of powerful Signalling Message Processing Machine to meet the full range of present and future communication control requirements, and aims to be a Professional、Essential、and Special company. So far Liangjiang has already owned series of innovation patents in communication control field. Our core technology—SigEngine, independent of existing network infrastructure, provides excellent solution to introduce personalized services Rapidly, Effectively and Robustly, with the same quality of service as current network. Its efficiency in mechanism has been verified in the field operating projects.

    SigEngine technology the state art of processor with fully distributed and replicated customer database into telecom network, breaks the service provision limitation of traditional technology, without changing carrier and signalling network structure. It provides an effective way to implement subscriber AAA(Authentication, Authorization and Accounting) Service, Number Portability (NP) Service, Billing Service, a full range of subscriber profile based Trigger Services and Signalling Message Added Value Services into a large-scale communication network. This technology has built the bridge toward NGN/3G for the existing network and meanwhile it enhances the access ability of HSS defined in IMS based next generation network.

    LJ 3000 a unique platform using SigEngine technology has supperexcellent characters: fully distributed service executing and centralized management, service implementation fast and independently, incomparable robustness and safety, no need to reshape existing network, no need to introduce new protocol, no need to calculate CAPS, quasi-real time billing independency and integrity, and operating management in global plan as a whole. The employment ofSigEngine technology will bring deep social influence to network intelligence and seamlessly convergence with NGN. The future safe mechanism and architecture bring the telecom service provision in a totally new stage.

    Our team has rich experience of more than 20 years in communication field with sensibility in product line and keen perspective in communication industry development. Especially has made a great contribution to SS7 technology and construction of China signalling network.

    Now our company has formed distinguished technology in communication control. Our view of core value is Quality, Innovation, Profession and Co-win:
