ABSTRACT
For munication operators who have iS essary for them tO use the good coverage of works to serve TD-SCDMA users when introducing TD—SCDMA technology,which requires roaming and handover between TD—SCDMA and ,it is important for US to study the handover/roaming strategy between them,and this will help operators to implement the handover and roaming between TD·SCDMA and works,and perform optimization based on service and application types.
The thesis analyze and study the handover and roaming principles between GSM
and TD—SCDMA specified by 3GPP,and explains how to implement it,which including work building strategy,parameter setting principle and how to do parameters optimization under different RF paper use the real signalling flow and test scenario to illuminate the questions need tO pay attention in work building and optimization,which will give guideline work planning,implementation and optimization.
The paper use the real example to explain work configuration and test plan for inter—system handover,and give examples for the possible issues during the test. For the important thing of neighbor cell planning in the optimization of
GSM/TD—SCDMA handover and ,based on the author’S working
experience,the paper give the idea and utilization result of the n
