Modify Advanced Call Control Parameters of Cell Call Control Parameters(MOD CELLCCAD)

Function

A configuration command that modifies the advanced call control parameters of a cell. In this command, the following parameters uniquely identify the cell:

Cell Index or Cell Name

Note

None

Parameters

ID Name Description
IDXTYPE Index Type

Meaning:Index Type

Value range:BYNAME(By Name),BYIDX(By Index)

Explanation:Index Type.

Default value:None

CELLIDX Cell Index

Meaning:Cell Index

Value range:0~2047

Explanation: This parameter indicates the source cell index. The source cell index must be unique.

Default value:None

CELLNAME Cell Name

Meaning:Cell Name

Value range:1-32 characters

Explanation: This parameter indicates the name of the source cell. The name of each cell under one BSC must be unique.

Default value:None

UPSENDSMDIS Short Message Uplink Disabled

Meaning:Short Message Uplink Disabled

Value range:NO(NO),YES(YES)

Explanation:This parameter specifies whether to disable the sending of point-to-point short messages. In specific cells, sending point-to-point short messages on the uplink is disabled to ensure sufficient radio channels for calls.

Default value:None

DNSENDSMDIS Short Message Downlink Disabled

Meaning:Short Message Downlink Disabled

Value range:NO(NO),YES(YES)

Explanation:This parameter specifies whether to disable the sending of point-to-point short messages. In specific cells, sending point-to-point short messages on the downlink is disabled to ensure sufficient radio channels for calls.

Default value:None

REASSFREQBAND Frequency Band of Reassign

Meaning:Frequency Band of Reassign

Value range:Same_Band(Same Band),Diff_Band(Different Band)

Explanation:In normal assignment procedure, after receiving the assignment failure message from the MS on the SDCCH, the BSC does not report the message to the MSC immediately. Instead, the BSC re-assigns radio channels and re-originates the assignment on the Um interface. Thus the success rate of assignment can be increased.

Reassigning radio channels can be performed in the carriers with the same frequency band or of different frequency bands.

If this parameter is set to Same Band, the frequency band of the preferentially reassigned channel is the same as what is used before the reassignment.

If the parameter is set to Different Band, the frequency band of the preferentially reassigned channel is different from what is used before the reassignment.

You can set this parameter to improve the deterioration of QoS caused by the interference, carrier channel fault, or engineering fault.

Default value:None

ASSRETRYMAX Max Assignment Retry Times

Meaning:Max Assignment Retry Times

Value range:0~3

Explanation:This parameter specifies the maximum number of reassignments after the assignment on the Um interface fails.

Default value:None

PREEMPTIONPERMIT Emergency Call Preemption Permitted

Meaning:Emergency Call Preemption Permitted

Value range:OFF(OFF),ON(ON)

Explanation:If this parameter is set to ON, the BSC initiates a TCHF preemption when receiving a link establishment indication.

Default value:None

EMCPRILV Priority of Emergency Call

Meaning:Priority of Emergency Call

Value range:1~15

Explanation:This parameter specifies the priority level of an emergency call.

Default value:None

Example

Modify advanced call control parameters of a cell (Index Type = BYIDX(By Index); Cell Index = 0):
MOD CELLCCAD: IDXTYPE=BYIDX, CELLIDX=0, UPSENDSMDIS=YES, DNSENDSMDIS=YES, REASSFREQBAND=Same_Band, ASSRETRYMAX=2,PREEMPTIONPERMIT=OFF,EMCPRILV=15;
