China is about to issue 3G licenses, and business fixed network operators currently facing a crucial period of transition.On one hand, in the full realization of fixed intelligent, the huge PHS network and user groups will continue to grow.business restructuring in full swing.At this stage, if the construction and operation of domestic fixed network operators 3G networkwe need to study the characteristics and status of traditional fixed telecommunications network, the 3G core network and PSTN further study.PHS, NGN architecture integration, FTNS operators to enhance the core competitiveness.
This paper summarized the situation in the mobile communications industry is reviewed based on the WCDMA technology standards development process.IMS components of the system and the principle of the traditional fixed telecommunications network status, characteristics and trends of development.elaborate structure of the fixed network operators are evolving core network technology development phase of the four lines.Note the correct choice for 3G core network development strategy and the importance of urgency.
Based on the above analysis and conclusions of this paper geared to fixed network operators 3G Core Network Architecture,the entire network architecture : the two new fixed telecommunications network based on the current situation.demonstrated that the circuit area of the 3G network PSTN (NGN), the two exchange programs.Detailed analysis of its signaling and media stream flow processes.Comparative analysis of the key differences agreement SIP and BICC, a proposed exchange options.2-6 to the eventual realization of the objective of the IMS framework of the integration process of the realization of database research.FTNS operators analyzed the current situation and development trend of user data, the characteristics and operational capabilities SHLR integration,SHLR introduction to business integration, network integration SHLR how the introduction of 3G network problemsFTNS operators in the final ahead of the introduction of 3GPP R4 network integration strategy in the database 2-6.
The proposal by the local fixed telecom network and the actual project implementation and operational opening of the preliminary certification.
