Hi all any good links on CAMEL Phase 3 and 4 architeture.28th July 2005 at 14:01 #40988IvanGuest
I need to source code V5.1 signalling protocol.
Please help me!12th September 2005 at 14:16 #40989haniGuest
i need to know about SDCCH drop reason. all immagining reason except the Quality(C/I) & congestion.
thanks.10th April 2007 at 10:01 #40990Soumendra PandaGuest
i am workink in Ericsson switch,
can anybody say me what r the signalings are required for a total gsm setup?10th April 2007 at 10:15 #40991neil nogueraGuest
hi sameer lo,
what exaactly do you want to know about softswitch3rd May 2007 at 16:01 #40992VKGuest
C7 – Absolute crap from operator side of view. Very good if you are a developer.
Softswitch – A step toward integrating your system & to welcome 3 G in respective circles.5th May 2007 at 16:16 #40993taGuest
I need materials ss7 signaling ,and wath difference between ss7 and MF(R2)signaling.
signaling over ip
thanks for your sending

VK…why do you think C7 is crap…any particular reason? Which signalling method do you think is best from an operator perspective? I work for an operator and we use C7 and I haven’t seen anything wrong with it so far…8th May 2007 at 15:04 #40995VKGuest
C7 is the best. It is very simple. It is not challenging though! Any one can get to learn about it. If you are devoloping it, then it is a different story!8th May 2007 at 15:52 #40996DudeGuest
That sort of contrasts with your earlier sentiments. From an operator perspective, I agree with your latter statement…C7 is very good. I wouldn’t know from a developer’s perspective since I’m not a developer though I’m considering going into development. Can you give me a pointer to resources that can get me started in developing protocols – C7 in particular?8th May 2007 at 16:58 #40997VKGuest
Yes, it is contrasting! That came with a lighter vein. I have been sitting on C7 for quite a long time now.
There is one similarity b/w you & me. I am also looking to get in to development, to be precise – C7.
I am also looking for details on it. Will share the resource if I come across any. But, can any one help us both?10th May 2007 at 07:50 #40998DudeGuest
It depends on the kind of switch you’re using and the nodes that you are connecting to. For example, if you are using a softswitch you have an option of using M2UA, M3UA or simply TDM based ss7. If you are also connecting to some nodes that also use sigtran then you can also use the above signalling protocols as well to connect to those. In the event that you have an IN system (or a RTBS) then you might need CAMEL as well.
I hope that gives you a rough idea of what to check for.14th May 2007 at 09:50 #40999KrishnanGuest
can anybody tell me about the M2PA?15th May 2007 at 11:29 #41000ABCGuest
Sameer Lo tried to start a genuine topic.
Plz Guys try to stick to this topic

Sorry for the late answer.
Lot of points in this thread/post.
Most CSPs – Communication Service Providers – have deployed 4G / IMS for VoLTE and ViLTE Services.
In LTE architecture, core network includes Mobility Management Entity (MME), Serving Gateway (SGW), Packet Data Network Gateway (PGW) and Enhanced NodeB (eNodeB).
3GPP can be used to look at the signalling / protocols. In particular, you can find information using Google and www dot 3gpp dot org.
Key areas to look at: L1, L2, SCTP, IP, S1-AP, X2, etc..
At the time of writing 5G is now being introduced.
3GPP TS 29.281 – GTP
3GPP TS 36.410 – S1 Layer 1
