hi mkt ๐Ÿ™‚
no i’m not irritated at all, don’t worry. i’m just answering very directly to your posts because it goes faster. sorry about that, i hope i didn’t upset you.

thanks for the explanations, it’s a bit clearer. Well, at least it’s clear that we’re misunderstanding each other, and it’s gonna be hard to settle this via internet…

do we agree that a TCH timeslot is stolen by the FACCH only to transmit the “HO COMMAND” message ? a HO COMMAND is a very short message so it uses only one or two bursts, max (i could check the message length in 3gpp … but no time ๐Ÿ™‚ )**** that’s the answer to the question (1) ****

So the FACCH is not the cause of the “blank” in the voice.

a HO duration is counted from the reception of a HO CMD to the first TCH is sent to the target cell : that is where the delay is : the MS has to access the target cell.

When the MS is connected to the target cell, it will start receiving the current speech frame, as being transmitted by the transcoder. I’m not sure why there would be delay in the TC, the TC works in real time. If a speech frame is not transmitted on the radio, then it’s lost forever.

***** regarding question (2) *****
i don’t understand (i’m sorry !! ๐Ÿ˜€ ). delay for MS-MS call : are you talking about call setup time from MS to MS ?
