VLR Subscribers:
D120 = NHLRMSST

COUNTER NAME:
NHLRMSST
Total no. of registered subscribers

OBJECT TYPE:
HLRSTAT

OBJECT NAME:
All the HLR IDs.


D121：忙時VLR開機用戶總數(shù)

D122：忙時系統(tǒng)試呼總次數(shù)
是指該地區(qū)交換機接受的各種用戶的話音試呼總次數(shù)。各種用戶包括市話用戶、模擬移動用戶、GSM用戶。話音試呼次數(shù)是指不包括短消等和增值業(yè)務(wù)，包括緊急呼叫和呼叫轉(zhuǎn)接的試呼次數(shù)。統(tǒng)計的消息為“CM service request”及IAM消息。(交換機間切換不算，因只有試呼無應(yīng)答不合理。)

System Call Attempts:
D122 = NCALLS of (MTACC488 + IEXTE + TRA + IEXSTT) – NANSW of (all MRNR + HOVER routes)

Explanation:

System Call Attempts: D122 = X01+X03+X05+X07-X09

X01: The number of mobile to land call attempts.

X03: The number of mobile to mobile call attempts.

X05: The number of land to mobile call attempts.

X07: The number of land to land call attempts.

X09: The number of IAM messages received, because of Incoming inter MSC HO attempts.


For X01 and X03, following counter will be used.

OBJECT TYPE
SAE

COUNTER NAME

NCALLS : Number of attempts to seize a record.

OBJECT NAME
MTACC-488This block is seized whenever a Mobile tries to originate a call.

X01+X03 = NCALLS of object MTACC-488 in object type SAE.

For X05 and X07, following counters will be used

OBJECT TYPE
MTRAFTYPE

COUNTER NAME
NCALLS : Number of call attempts.
This counter in incremented when an IAM message is received from PSTN ( for an incoming
call ).


OBJECTS NAMES
IEXTE, TRA , IEXSTT : These objects are related to the incoming-terminating calls, transit and incoming external system terminating calls.

X05+X07 = NCALLS of ( IEXTE+TRA+IEXSTT ) in object type MTRAFTYPE.

For X09 , following counter will be used

OBJECT TYPE
LOSSROUTE
COUNTER NAME
NANSW : Number of answers.
This is modified counter, which is incremented when an incoming inter MSC HO attempt is made to the MSC.

OBJECTS NAMES

System Call Answers:
D123 = NANSW of (ORGOEX + INT + SOTTE + SOTOEX + IEXTE + TRA) – NNBRHBAISDHTOT of (all neighbour MSCs)

Explanation:

System Call Answers: D123 =X02+X04+X06+X08-X10

X02: The number of mobile to land calls answered.

X04: The number of mobile to mobile calls answered.

X06: The number of land to mobile calls answered.
