[@jibrankhalil662]

The video is very useful. I am a finance professional but engaged on the financial audit of telecoms. This video ia very useful to understand GSM system very well... Keep it up.

[@ericabui5961]

Many thanks doctor, i can see you have deep knowledge of the whole Mobile Core. i needed some clarification and i am satisfied

[@jameswarburton3727]

I have a question how do you bypass the pstn with connection a void phone call over the wan instead of the pstn? how do you get the phone numbers dynamic ip dress and ring the phone? like magic jack?

[@ahmahdy]

great explanation, but i just to add an info; i.e, the new architectures now allow the the OMCs to be connected directly to the BTSs directly.

[@ANALOGTecHII]

hello sir can you please share how the frequency is allocated dynamically in gsm , methods of frequency allocation apart form tdma fdma and cdma

[@rozanaalam4426]

thank u so much sir... it's very informative and easy to understand.... may ALLAH bless u...

[@sunnybhargava5234]

thanks a lot... lucid and impressive explanation...

[@diazzandress]

Hi Dr. Moazzam, first of all, thanks for the way how your share your valuable information, I'm a telecommer with a M. Eng and I still find this as gold. I just wanted to make an appreciation, in 12:35 you're explaining the relation of the different Data Bases with the MSC, and makes me wonder if the OMC could be considered as a data base?
Thanks again.

[@dr.moazzamtiwana4743]

Thanks for your kind comments. Yes, OMC could be considered as a database, as the alarms and performance reports from the network can be stored in its database.

[@veenajha6023]

Thanks a lot for such a wonderful explanation. Have you posted videos for 3g and 4g also ?? Please share the link if so.

[@rajasekarans9535]

Very Good Explanation Sir ... Thank You

it is very useful explanation , thank's dr.moazzam

[@rizwanudoy8280]

Thank you Mr. Tiwana for uploading such a easily understandable video. I have two questions though.
1. GSM is a circuit switched network while UMTS, LTE involve packet switched functionalities. Does that mean that, when one subscriber is engaged in a call in GSM, the channels allocated to him is fixed during the entire time of the call process, while in 3G and 4G, the channels allocated to the user is not fixed, and voice and data can travel through different channels based on channel condition?
2. If 4G is an all IP system, does that mean it runs on Internet Protocol (IP) and every device gets an IP address?
Thanks again for the video.

[@dr.moazzamtiwana4743]

1) In GSM Voice channels are fixed if you are not doing frequency hopping.
2) In 3G you have separated entities in core network to handle Circuit switched and packet switched calls. Circuit switched call is handled in similar manner as GSM.
3) Yes, in 4G the Mobile gets the IP address everytime it makes a call, however it is a private IP address.

[@rizwanudoy8280]

Thank you Sir for replying.

so good ,i hope you succeed doctor.

U took my Viva..... IP college dcn subject

[@bharatmv1931]

my doubt is about frequency usage.
if no neigboring cells should have same carrier frequency ,den the mobiles which work in the same cell will use same carrier frequency,in dat case is der interference b/w two mobiles?if NO ,Y?IF YES y?

[@dr.moazzamtiwana4743]

There is no interference in a cell. For more details refer to my video on What are frequency bands of GSM and another video on frequency reuse in GSM

[@bharatmv1931]

yeah thank u sir ,got it .
