Beginners: Simplified Call Flow Signaling: Registration - The Attach Procedure

This video provides an example of the registration procedure. The device or UE needs to let the core network(s) know that it is switched on and active. This procedure is known as registration. The UE can register individually to the CS and PS core networks. Most modern networks allow combined registration (or combined attach) whereby the UE registers only to the PS network and the PS network informs the CS network that the UE is active.

This is good video for beginners, excellent presentation. With this people can start learning in depth but first they gotta know the basics

[@bzyksyn3950]

That is how education should be. You explain thing is very clearly without all this confusing terminology.

[@IgorOzz]

Excellent presentation. Communication is clear and the content is very objective. For a beginner "intro", it is just perfect.

msisdn is no embedded in the SIM. It i provisioned to the phone on ISD

[@manmadhreddy4349]

Good Work

[@horizonbrave1533]

Thanks 3G4G, Does the communication between the UE and the Access Network Nodeb's, is this communication encrypted? Also, is voice traffic and signaling sent both on the same "channel" to the Access Network? I know in the IMS core Signaling and Voice/Data is separated. For Example SIP is used for Signaling and H248 is used for Data/Voice. But is the same true for the UE to Access Network communication?

[@3G4G5G]

Yes, of course. You may want to jump to the presentation on Security as that will provide you all the relevant details.

[@omprakash4292]

Hi thanks a lot first
If pss and sss is high utilities, what to be done?

[@3G4G5G]

Om, its not clear what your question is. Could you rephrase it please.

[@hsar25]

Nice explaination sir....sir please solve this doubt...there is no problem with UE as well as network side..but still UE unable to camp on the network..what might be the reason.. please solve

[@3G4G5G]

This could be a long and technical discussion. We would suggest discussing it on this LinkedIn group: www.linkedin.com/groups/1180727/

[@hsar25]

Thank you sir

[@teliat6242]

What modern network? It doesnt make the sense. Pls mention like that HLR in GSM & UMTS and HSS in LTE/EPC. Pls be detailed when you explain so that audience will clearly get the point.

[@3G4G5G]

This is for newbies, experienced people like yourself should be reading the specs.
