ON DEVELOPMENT OF IP WORK
ABSTRACT
This paper discusses the necessity of the development to the IP work and the work restructuring paper posed of two one discusses the IP GSM work and part two discusses the IP GSM work.
The fist section analyzes the feasibility and inevitability of the IP GSM work from the aspects of industry development,technology evolution,work architecture second section analyzes standard process of the IP BSS.~ evolution can be
implemented for the IP BSS in three third section is the main part:typical IP BSS solutions,including IP solutions on the Abis,A and Gb section elaborates the Abis Over IP solutions for ,,and addition,
this section discusses the advantages and disadvantages of each
fourth section discusses six work topologies:microwave-based FE,
E1,+xPON,+ xPON++SDH+SHDSLSHDSL-based Abis Over fifth section discusses the special solutions of the IP
the Clock Over IP fiIlal section summarizes the advantages of the IP BSS.
The second part provides the evolution of the work and draws the conclusion that the work will gradually replace the traditional TDM
and part provides prehensive
Ⅱ
description of the restructuring principles and solutions of the IP work,including work restructuring,IP work restructuring,work planning,work work security,
IP QoS,and discussion of each aspect involves the technology foundation,planning principles,and work topologies.
With the development of the work from 2G to 3G,and then to
LTE,the work will evolve in the direction of broadband,packet,and the development to the IPv6/works is ,the IP transmission is launched on the work of China IP work is plete and the IP BSS is in good is believed that the IP work will inje
