The multi-service bearer network,built upon the Internet Protocol/Multi-protocol Label Switching (IP/MPLS) technology,is a converged network with Quality of Service (QoS) guarantee for business and enterprise customers. The integrated and unified service provisioning platform (including both service execution and development enviroments) can provide integrated audio,video and data services over multiple access networks. However,achieving network convergence and service convergence are long-term goals,which can only be realized step by step after comprehensive consideration of many factors like market demands,technologies,services and costs.展开更多

Service convergence includes two aspects: The convergence of the fixed and mobile networks; and the convergence of traditional communications and Internet services. This requires balancing the conflicts between the openness and operationability of terminal capability and network convergence. Unified authentication and authorization are the basis for service convergence in terms of operationability. Modular network and open terminal are technical solutions for the service convergence.展开更多

In the process of promoting the commercial usage of IMS services, the Service Delivery Platform (SDP) is evolving into a more convergent and open Service Delivery Environment (SDE) and will become the mainstream of the next generation Telecom Service Network. ZTE’s concept of the Converged Service Network (CSN) is to integrate various network service capabilities to realize the unification of data, service, capability and management and thus the fast provisioning of various Value-Added Services (VASs), which helps the carriers to maintain a leading position in the value chain, meeting the telecom carriers ’ requirements for service network development.展开更多

It involves integrally developing telecom networks and Internet businesses through the convergence of their instant news and social networking services. Some background, benefits for telecom operators, and possible challenges are analyzed. A new service convergence approach such as this can also facilitate triple-screen and multi-screen convergence in the future.展开更多
