Performance Analysis And Planning Of Broadband IP Metro Area Carrying Network And Its Access Network

Recombination of the telecom operators makes the telecom industry enter a full service competition. With the rapid increasing of service demand of mobile Internet, the integration of Internet and mobile communication network is further intensified, and the mobile Internet is becoming the main trend of communication networks. On January 13, 2010, the State Council Standing Committee decided to speed up the integration of the telecom network, CATV network and Internet(I-TNCNI), which will exacerbate the full service competition between the three industry operators. The integration not only brings the CATV network opportunities but also challenges.CATV network operators still carry out the CATV video service as the main service currently, which is difficult to meet the multi-service requirements of subscribers. CATV network can offer Internet access for fixed subscribers within the district, but can not provide voice service and broadband mobile access service. In the competition, in terms of network infrastructure, operating experience, network maintenance and capability of service development, CATV network industry is at a disadvantage. Therefore, it is one of the most urgent tasks for CATV network operators to make full use of the network resources, bandwidth and content advantages, and adopt the latest technology to rebuild, expand or build a new broadband IP metro area carrying network(B-IP MACN) and the existing cable access network including HFC(Hybrid fiber Coax) and Ethernet. The other ergent task is to build the Broadband Wireless Access Network(BWAN) and make the network infrastructure be suitable for carrying multi-service in the future.Under the background of I-TNCNI, the research focuses of the thesis are mainly related to the planning and construction of B-IP MACN and BWAN. Firstly, the opportunities which I-TNCNI brought to CATV network operators, the status of B-IP MACN and the necessity of constructing BWAN were introduced. The existing typical broadband wireless access technologies were compared and the advantages of McWiLL applied in trade special network were analyzed. Secondly, regarding the status of CATV network in A City, the planning scheme of B-IP MACN was proposed to meet the needs of BWA according to the current carrying network of IP data service. Finally, the planning scheme of B-IPMACN-based BWAN was proposed and the coverage capability and the capacity of BWAN were predicted and simulated by choosing typical region. By comparing the measurement data with the prediction data of a base station, the feasibility of the planning scheme was verified.
