1)Difference between GSMSC and IWMSC?
2)
A)I understand that GMSC is an MSC for connecting to the PSTN. Is it a seperate MSC dedicated for connecting to the PSTN or is it just a SW function of the MSC?
B)In a mobile network, and that the HLR is assoicated with the GMSC(not the MSCs) while
each MSC with have its own VLR. Is this a usual configuration for a mobile operator?
Any one can reply me Plz?
