CCCH- 载频类型之一；(xxCH) type of current channel:
　
　
* AGCH -(Access Grant Channel)允许连接频道由网络到手机的单向频道，安排专用控制信道以完成连接上网；
* SDCC -(SDCCH:Stand-alone Dedicated Control Channel)独立专用控制信道；
* TFR -(TCH:Traffic Channels)业务信道；
* BCCH -(Broadcast Control Channel)广播控制信道；
*SEARCH-手机正在搜索的网络信号；
* NSPS -(No Service & Power Save),无网络服务，手机正处于省电模式；

通话中CHT项变化:AGCH->SDCC->TFR->挂断电话->CCCH
开机时CHT项变化:AGCH->SDCC->BCCH->CCCH
•AGCH - Access Grant Channel - is the answer to RACH. It's used to assign a mobile a Stand-alone Dedicated Control Channel (SDCCH). It's downlink and point to point channel.
•SDCC - (SDCCH) Stand-alone Dedicated Control Channel - It's used for system sygnalling: cell set-up, authentication, location update, assigment to traffic channels and transmission of short messages
•TFR - (TCH) Traffic Channels - Physical channels also transfer user data, which can be either in the form of Half Rate traffic (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 normal 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:
•　
oFrequencies used in the particular cell.
oFrequency hopping sequence.
oChannel Combination. In the GSM 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 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 cell
oPaging groups. Normally in one cell there are more than one paging channels. 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.
oInformation on surrounding cells. A mobile station has to know what are the cells surrounding the present cell and what frequencies are being broadcast on them. This is necessary if, for example, the user initiates a conversation in the current cell, and then decides to move on. The MS has measure the signal strength and quality of the surrounding cells and report to the base station controller.
•SEARCH Mobile Station is searching for signal.
•NSPS (No Serv Power Save)

With this display is possible to change MS to use DTX or not if BS allows MS to decide it.
To change DTX state, You must activate this display from MENU. When MENU is not active and the user is scrollinng field test displays with NEXT and PREVIOUS, the DTX state will not change
•xxxxxxxxxxx is status of switched mode. The values are:
oDTX ON (MS use DTX)
oDTX OFF (MS not use DTX)
oDTX DEF (MS use default state of DTX Defined in MS_PAR.H)
oNOTALLOWED (BS not allows MS to decide if it uses DTX or not)
•yyyyyyyyyyyy is default state of DTX, definned in MS_PAR.H. Values are:
oMS DEF: ON
oMS DEF: OFF
•zzzzzzzzzzzz is DTX value from BS. The values are:
oMS MAY USE (BS allows MS to decide if it uses dtx or not on uplink
oSHALL USE (BS controls MS to use dtx (on uplink))
oSHALL NOT (BS controls MS not to use dtx (on uplink))

If OFF - Mobile is behaving nornally. Neigbour mesurements are done
To change status from OFF to ON write to SIM memory #33 channel number, go to menu 10-17, turn POWER OFF and again ON. Now You have active BTS TEST!!!

This test is meant to be used when some cells are tested prior taking them into commercial use. By setting the barring on in the base station normal GSM phones will not try to register these barred cells. By selecting cell barring reversed, the MS will only use the cells to be tested. However, if at the same time it is wanted that MS will be capable to use normal network cell barring ignored can be set.
This test can be activated only from the MENU selecting item field test, or with shortcut menu-10-19. When MENU is not active and the user is scrolling field test display with NEXT and PREVIOUS, display 19 won't be activated.
