SYS INFO 2TER and SYS INFO 3

SYS INFO 2TER

 2TER contains neighbor BCCH frequencies (part of BA1 list). It is transmitted on BCCH. Only dual band MS can read this information, and single band 900 or 1800 MS will ignore it. Since this information carries BCCH frequencies that belong to different band as those in SYS INFO 2, it is unnecessary for single band MS to read.

 

SYS INFO 2TER - - Neighbor Cell Desc. (extended)        

 

Except the fifth bit (BA_IND), sixth, and seventh bit (Multi-band reporting) of the second byte, the coding of other information is the same with cell channel description.

SYS INFO 3

It contains LAI, cell identity, RACH and parameters related to cell selection. It is transmitted on BCCH. It is one of the most important information in SYS INFO.

 

SYS INFO 3 - - Cell Identity

        - -  LAI( location area identity)

        - - Control Channel Desc

        - -  Cell Option（BCCH）

                    - -  Cell Selection Parameter                    

                    - -  RACH Control Parameter
