No GPRS connection with some devices
John:
Hi,
I installed yate and yateBTS on Debian sistem with a Bladerf x115 and i can easily call and send sms, with bot and with 2 device in the same network (I'm in NiPC MODE).
I can connect with no problem iphone 5s (apple SOC) and Huawei (Qualcomm SOC) in GPRS but i cannot get any connection with my Honor (Kirin Soc) smartphone, i thing that is something related to the different modem because similar post
here : https://forum.yate.ro/index.php?topic=1927.0
and here : https://forum.yate.ro/index.php?topic=1843.msg5990#msg5990
but i have no responce to my questions.
On attachment you can find the GGSN and SGSN log and a wireshark pcap, both related to honor smartphone connection.
Versions:
--- Code: ---Yate 6.0.1 devel1 r6313

--- Code: ---bladeRF-cli version: 1.6.1-2018.08-release-1-ppabionic

John:
I'm trying to go deep into the problem, i fond some difference in my devices and i wanna show to you.
In the GGSN log for the honor device i got a persistent loop blocked into "RAU"

--- End code ---
for the huawei device.
I thing that GPRSMultislotClass is not a problem but GERANFeaturePackage1 may be a problem cause searching in the source code i found only this:
--- Code: ---// Extended dynamic mode means # channels up > # channels down.
bool MSInfo::msCanUseExtendedUplink()
{
// The Blackberry and iphone set the GeranFeaturePackI bit, but
// the danged Multitech modems truncate the MS capabilities before
// the GeranFeaturePackI bit, even though they do support extended uplink TBF
// They are multislot class 12, so if the MS multislot class > 10, assume ok.
return gL2MAC.macUplinkPersist > 0 && this->msIsRegistered()
&& (this->sgsnGetGeranFeaturePackI(this->msTlli) ||
this->sgsnGetMultislotClass(this->msTlli) > 10);
}
