Why only set T1,T2,T4 under mobile network #120

In this file
https://code.google.com/p/rcsjta/source/browse/core/src/com/orangelabs/rcs/core/
ims/protocol/sip/SipInterface.java

There is a part to set retransmit timer,

        // Set timers value from provisioning for 3G or default for Wifi
        if (networkType == ConnectivityManager.TYPE_MOBILE) {
            this.timerT1 = RcsSettings.getInstance().getSipTimerT1();
            this.timerT2 = RcsSettings.getInstance().getSipTimerT2();
            this.timerT4 = RcsSettings.getInstance().getSipTimerT4();
        }

But, why only for mobile type?

There are different timers defined by 3GPP IMS spec when you are connected to a 
fix network acess or to a mobile network access.

Thanks a lot.

And just to be curious, could you please hint me which 3gpp document mention 
the different timers of network type?

It's the following spec 3GPP TS 24.229, in the chapter "SIP timers".
So we use column 1 for fix network (timer value defined in SIP RFC in fact) and 
we use column 2 for mobile network.
So we consider the Wi-fi as a fixed network, now I m now sure to be right or 
wrong. So I will confirm with Orange experts.

Column 1 is for network endpoint only. So timer value should be the same for 
mobile and wifi network access in the UE. I will do a patch in the integration 
branch from the new repository only at https://github.com/android-rcs/rcsjta. I 
will close the issue when it is done.
