Difference between Mobile Originataing Call(MOC) and Mobile Terminating Call(MTC) ?

Hi,

I could not get the difference between MTC and MOC? Is MTC is continued part of MOC?

What I understood is : MOC is originating call i.e., when we dial a number. But MTC smells fishy. Is it terminating call in the sense the call releasing method or what? But the call flow of MOC and MTC is as follows:

MOC Is MTC continues from here? MTC
MS(Calling party) --- >BSC --- >MSC/VLR ---> PSTN | PSTN ----> GMSC ----> HLR ----> MSC/VLR ---> BSS ---> MS(Called party)

Is my above understanding correct?

MOC vs MTC

What you described is a whole call process
MOC: MS (A party)->BSC->MSC/VLR
MTC: MSC/VLR->BSC->MS (B party)

MOC starts from A party sending service request to core network
MTC starts when core network receives B number and start analysis for paging, or IAM sending

MOC-Mobile Originating Call
MTC-Mobile Terminating Call

In layman Language the Mobile/MS which initiate a Call is,that call is known as MOC.
where as the destination Mobile/MS for which the call has been initiate is known as MTC.
