SS7 newbie: How to get and query subs data through ss7?

Hi,
I'm new to SS7 and I would like to know if there are SS7 messages that can be sent through that can obtain subscriber data? For example, my switch is connected to a GSM network via SS7 links and I want to send query to that network to know if a subscriber has supplementary services. Just queries, no actual calls.
Hope you guys can help me.
Cheers!

Yes, Via SS7 you can query

Yes,
Via SS7 you can query the data.
Like from HLR, you can have information of the subscriber.
& for that your switch can ask for some SRI (Send routing Info), SAI(Send Authentication Info) & ISD(Insert Subscriber Data) to HLR.
In ISD, you can get supplementary services.

What is the invoking event for ISD

From my switch, I can send SRI and SAI. But isn't it that ISD is an HLR response during location update? Is there a message that I can send from my switch so that the HLR can send me an ISD?

U need message from HLR when

U need message from HLR when requested, right?

Are you making some application or what ?

For research

Yes I need message from HLR but I also need to know what message i should send from my switch so that the HLR will respond me with an ISD. Is there a trigger message that HLR will respond with an ISD?
I'm not making an application, just for some research.

Thanks Pramod,

for your favourable response...
as now i had tried with MSC/VLR but got the same result....
As per customer said that there are some restriction into HLR so whenever ISD comes from MSC/VLR there must be properly message from the MSC/VLR...

as customer HLR configuration is below

HLRSN = 1
TPLID = 1
TPLNAME = OCSI1_PB
CAMEL = PHASE2
DP = COLLECTINFO
SK = 51
GSMSCFADD = 919080560010
DEFAULTCALL = Release Call
WITHROAMAGRE_SUPCAMEL = ReturnO-CSI
WITHOUTROAMAGRE_SUPCAMEL = DenyLocationUpdate
HPLMNROAM_SUPCAMEL = ReturnO-CSI
WITHROAMAGRE_SUPLPCAMEL = DenyLocationUpdate
WITHOUTROAMAGRE_SUPLPCAMEL = DenyLocationUpdate
HPLMNROAM_SUPLPCAMEL = ReturnLPO-CSI
WITHROAMAGRE_NOTSUPCAMEL = DenyLocationUpdate
WITHOUTROAMAGRE_NOTSUPCAMEL = DenyLocationUpdate
HPLMNROAM_NOTSUPCAMEL = DenyLocationUpdate
WITHINTERAGRE_SUPCAMEL = ReturnO-CSI
WITHOUTINTERAGRE_SUPCAMEL = ReturnBAIC
HPLMNINTER_SUPCAMEL = ReturnO-CSI
WITHINTERAGRE_SUPLPCAMEL = ReturnBAIC
WITHOUTINTERAGRE_SUPLPCAMEL = ReturnBAIC
HPLMNINTER_SUPLPCAMEL = ReturnBAIC
WITHINTERAGRE_NOTSUPCAMEL = ReturnBAIC
WITHOUTINTERAGRE_NOTSUPCAMEL = ReturnBAIC
HPLMNINTER_NOTSUPCAMEL = ReturnBAIC
CAMELROAMTPL = 1

Total count = 27
