| Abstract: |
| According to LTE high layer protocol of terminal cell selection and a
suitable and acceptable cell condition,the normal proce
ss of cell selection is analyzed with focus on the subsequent cell sele
ction process when the above condition is not satisfied. The corresponding desi
gn flow is given.
And the MSC (Message Sequence Charts) is produced using SDL (Specification and D
escription Language) and TTCN (Tree and Tabular Combined Notation) co-simulation
.The simulation result shows that the design
can effectively complete the required cell options by specification. |
