2G 3G HO

1. Does 2g to 3g voice handover work on o2?

When I am cruising in my automobile, I notice that when I recieve a call and it a
handover occurs from 3g to 2g, it never performs any subseqent handover to 3g until
the call completes. Is this a network or possibly handset (Galaxy Note 3) limitation?
I wouldn't normally be bothered, but 2g call quality on o2 seems to be atrocious - a third
of the time it sounds like the person speaking to you is standing behind a desk fan. Call
quality when connected to a 3g cell sounds glorious in comparison.
Solved! Go to Solution.

Certainly not a network limitation as I can take calls on 3G no problem. 2G is usually
good too on the occasions I am in a 2G only area so I would start by suspecting a sim
fault and work from there.

Hi MI5.. I'm unsure if you understood my question. What I'm concerned about is that
during a voice call on 2g, a handover to 3g doesn't appear to occur until the call stops.
Example:
1. Call starts in strong 3g area
2. Part way through journey, not in 3g area so call drops to 2g
3. Come back into strong 3g area - call remains on 2g network
4. Call ends in strong 3g area. Phone remains in 2g mode for a few seconds, then
handover to HSDPA network completes.

Right OK - Thought you meant it dropped to 2G immediately you had an active call,
sorry. In all honesty I would expect that to be normal behaviour but I tend not too take
any notice of the signal indicator when I'm driving....

My educated stab at this is
Once handover to 2g network has happend due to it being only data or voice and not
data&voice like 3g, the handset is not looking for a data connection until the voice call
drops so it holds the 2g connection untill the call ends and then starts to look for fastest
data network 2g 3g or 4g and then reconnects to 3g.

My first mobile was in 1995 a CM-R111 from sony on Cellnet.
