From my observation, the delay caused by the radio resource allocation varies a lot over time and seems it is not only caused by the radio access network. So I was wondering what network devices are involved in the radio resource allocation besides the phone, base-station and RNC? And what are the factors that can potentially affect the observed delay?
If the phone is in idle, I believe the GTP tunnel changes status as well so also SGSN/GGSN is involved. I'd imagine the transport network between all the devices can affect time as 3GPP likes to reserve resources everywhere, so it might be that a lot of transport network devices could potentially be included as well. -- Mikael Abrahamsson email: swmike@swm.pp.se
