Description

Be used for the user preposition equipment that heterogeneous network merges

Technical field

The invention belongs to the data communication field, particularly relate to a kind of user preposition equipment that heterogeneous network merges that is used for.

Background technology

The integration of three networks of voice network, the Internet, television network is the development trend of ICT; The notion that China proposed the integration of three networks as far back as 1998; Data communication is the high speed development of computer internet especially; Insert from the broadband optical communication of 100M Fiber to the home FTTH today that dials up on the telephone of telephone wire 33Kbps; The clear and definite final development track of fixed network broadband network realizes being tending towards ripe based on the integration of three networks technology of the communication of FTTH fiber optic network voice-bearer, data communication and DTV.

Networks development is along " light advances copper and moves back " trend evolution; And carrier network construction and transformation are to consider professional growth needs, available resources and investment repayment, and the network rebuilding is for more business carryings needs, new business and new is used the promotion network rebuilding.Under the overall situation of the integration of three networks at present; Will form the 3+1 operator general layout of competition comprehensively; The upgrading of network is an important process that lays the foundation for service competition from now on; But relate to the network rebuilding investment of hundred billion yuan of orders of magnitude, different its investments for trnasforming urban land of different operators network foundation are widely different, are " too much difference between the rich and the poor ".Because the business development cycle and the network rebuilding and asynchronous or coupling; The network rebuilding has been invested down and maybe business development has not been complied with one's wishes or certain lag period is arranged; Business demand is come soon and the network rebuilding does not catch up with and misses the chance of commencing business, and the result who causes is that the big benefit of investment is low.

It is thus clear that, like how less cost, improve the utilization ratio of existing network, reduce investment risk, be the key subjects that integration of three networks engineering faces.If can under the prerequisite of not transforming existing basic network, only realize the mutual usefulness of each network, be undoubtedly the higher integration of three networks scheme of a kind of cost performance through scrap build.

Summary of the invention
