8、icated Control Channel - It's used for system sygnalling: cell set-up, authentication, location update, assigment to traffic channels and transmission of short messagesTFR - (TCH) Traffic Channels - Physical channels also transfer user data, which can be either in the form of Half Rate traffic (

9、6.5kbit/s) or Full Rate (13kbit/s). Another form of traffic channel is the Enhanced Full Rate (EFR) Traffich Channel. The speech coding in EFR is still dona at 13kbit/s, but the coding mechanism is different than that used for normal full rate traffic. EFR coding gives better speech quality than nor

10、mal full rate. Traffic channels can transmit both speech and data. these are bi-directional channels.BCCH - Broadcast Control Channel contains detailed network and cell specific information such as:o Frequencies used in the particular cell.o Frequency hopping sequence.o Channel Combination. In the G

11、SM there are eleven logical channels. Depending on the number of frequencies used in a cell, the number of physical channels available is eight times the number of used frequecies. most of these physical channels have to be allocated for traffic purposes. There are more than one ways in these aleven

12、 logical channels are mapped on the available physical channels. How they are mapped varies from cell to cell depending on a number of categories. Channel combination tells about the mapping method used in the particular cello Paging groups. Normally in one cell there are more than one paging channe

13、ls. To prevent a mobile to listening to all the paging channels for a paging message, the paging channels are divided such that, a group of mobile stations listen to a particular paging channel only.o Information on surrounding cells. A mobile station has to know what are the cells surrounding the p
