Syntax
EQH : ( BTS = <BTS identification> | NAME = <BTS name> |
SEG = <SEG identification> <option> | SEGNAME = <SEG name> <option> ) :
( MQL = <max queue length> | TLC = <time limit call> | TLH = <time limit handover> | QPU = <queue priority used> | QPC = <queueing priority call> |
QPH = <queueing priority urgent handover> | QPN = <queueing priority non-urgent handover> | MPU = <MS priority used> ) ... ;
Parameter explana-tions
BTS identification BTS = decimal number
With this parameter you identify the BTS by its number. The value range depends on the BSC hardware configuration and the corresponding options.
If you give this parameter, you cannot give the parameters NAME, SEG, or SEGNAME.
You can use the parameters BTS, NAME, SEG, and SEGNAME if the segment has only one BTS; otherwise you must use the parameters SEG or SEGNAME.
BTS name
NAME = text string
With this parameter you identify the BTS by its name. The name can contain 1 to 15 characters.
If you give this parameter, you cannot give the parameters BTS, SEG, or SEGNAME.
You can use the parameters BTS, NAME, SEG, and SEGNAME if the segment has only one BTS; otherwise you must use the parameters SEG or SEGNAME.
SEG identification <option>
SEG = decimal number
With this parameter you identify the segment. The value range is the same as the BTS identification value range.
If you give this parameter, you cannot give the parameters BTS, NAME, or SEGNAME.
You must use the parameters SEG or SEGNAME if the segment contains more than one BTS.

SEG name <option>
SEGNAME = text string
With this parameter you identify the segment by its name. The name can contain 1 to 15 characters.
If you give this parameter, you cannot give the parameters BTS, NAME, or SEG.
You must use the parameters SEG or SEGNAME if the segment contains more than one BTS.
max queue length MQL = decimal number
With this parameter you define how many call and handover attempts can be queued to wait for a TCH release in a BTS.
A TRX with full rate TCH resources builds up eight possible queue positions. When a TRX contains at least one half rate TCH resource, the number of queue positions is doubled to sixteen. Every deleted TRX removes eight/sixteen possible queue positions, respectively. The parameter value is a percentage (0 - 100%) of the TCHs in use in a BTS.
When this parameter value is 0, the TCH cannot be queued for in the BTS.
When this parameter value is 100, the number of available queue positions is the same as the number of queue positions in the configured TRX/TCHs.
Values between 0 and 100 give the number of available queue positions as a percent-age of the number of queue positions in the configured TRX/TCHs.
Note that the actual number of call and handover attempts cannot be greater than 32 in the BTS.
time limit call
TLC = decimal number
With this parameter you define the maximum queuing time for call attempts (incoming or outgoing) in the BTS in seconds. The values range from 0 to 15 seconds.
If you enter the value 0, call attempt queuing is not active in the BTS.
time limit handover TLH = decimal number
With this parameter you define the maximum queuing time for handover attempts (both urgent and non-urgent) in the BTS in seconds. The values range from 0 to 10 seconds.
If you enter the value 0, handover attempt queuing is not active in the BTS.
queue priority used
With this parameter you define whether the BSC internal queuing type priority (param-eters queueing priority call (QPC), queueing priority urgent
handover (QPH), and queueing priority non-urgent handover (QPN)) is taken into account in queue handling.
The values are:

queueing priority call QPC = decimal number
With this parameter you define the call attempt priority in the BTS.
Queueing priority call is one of the queuing type priorities. The others are: urgent han-dovers (parameter QPH) and non-urgent hanhan-dovers (parameter QPN). Note that you have to define the QPU parameter value as Y before the queuing type priorities are taken into account.
Relationships between the queuing type priorities:
• paired comparison is followed between the queue priorities • queue type of higher priority is the preferred one
• queues having the same priority are treated equally The priority scale is 1 - 14, where 1 is the highest priority.
queueing priority urgent handover QPH = decimal number
With this parameter you define the urgent handover attempt (queuing type) priority in the BTS.
Queueing priority urgent handover is one of the queuing type priorities. The others are:
call attempts (parameter QPC) and non-urgent handovers (parameter QPN). Note that you have to define the QPU parameter value as Y before the queuing type priorities are taken into account.
Relationships between the queuing type priorities:
• paired comparison is followed between the queue priorities • queue type of higher priority is the preferred one
• queues having the same priority are treated equally The priority scale is 1 - 14, where 1 is the highest priority.
queueing priority non-urgent handover QPN = decimal number
With this parameter you define the non-urgent handover attempt (queuing type) priority in the BTS.
Queueing priority non-urgent handover is one of the queuing type priorities. The others are: call attempts (parameter QPC) and urgent handovers (parameter QPH). Note that you have to define the QPU parameter value as Y before the queuing type priorities are taken into account.
Relationships between the queuing type priorities:
• paired comparison is followed between the queue priorities • queue type of higher priority is the preferred one
• queues having the same priority are treated equally The priority scale is 1 - 14, where 1 is the highest priority.
N Queue priority is not used.

MS priority used
With this parameter you define whether the call priority in the ASSIGNMENT REQUEST message (or the HANDOVER REQUEST message in handover) from the MSC is taken into account in queue handling.
The values are :
Examples 1. Modify the queuing parameters of BTS-20.
ZEQH:BTS=20:MQL=20,TLC=12,TLH=10;
2. Modify the queuing parameters of BTS-20.
ZEQH:BTS=20:QPU=Y,QPC=5,QPH=4,QPN=6,MPU=Y;
3. Modify the queuing parameters of BTS CENTRUM1.
ZEQH:NAME=CENTRUM1:QPU=Y,QPC=5,QPH=4,QPN=6,MPU=Y;
