As the owner of a manufacturing business, I’ve come to realize how crucial efficient logistics are. When I first started exporting products overseas, handling shipping on my own was a constant struggle. After partnering with a freight forwarding service https://www.cfipak.com/ , everything changed. They handle the complexities of shipping, customs, and delivery, allowing me to focus on production and growth. With their expertise, my shipments are now timely and cost-effective. If you're in manufacturing or any business with global reach, investing in a freight forwarding service will save you time and stress, helping your business thrive.

Dear list, I wonder if anyone has access to Nokia Flexi BTS or Flexi EDGE / Multiradio equipment and can provide access to it for the purpose of adopting Osmo-BSC to support for these units? In case someone has a unit like this (with whatever radio), please let me know. Regards, Csaba

Is It Worth It to Pay Someone to Take My Online CompTIA Exam?

by olivianaylor322＠gmail.com

I’ve been struggling with my CompTIA exam prep and honestly, it's been hard to manage everything. The idea of asking someone to take my online CompTIA exam for me https://www.theresearchguardian.com/take-my-comptia-exam-for-me/ seemed a bit extreme at first, but after seeing how many students do it, I’m starting to consider it seriously. If anyone has tried this service, I’d love to hear your thoughts. Was it worth the investment? How reliable were the test takers? I just want to make sure I'm making the right choice.

Separate RSL bootstrap to LAPD and BCCH+SACCH

by Sipos Csaba

Dear list, At the moment setting up the RSL lapd link and start its bootstrap (BCCH info and SACCH filling) is done in one go (as much as I can see). The issue with this is for the Nokia Site family: per spec. we should let the RSL lapd link to be initiated by the BTS and once that lapd link is up, the BTS sends a BTS_STATE_CHANGED message with "TRX, enabled" object id and object current state, and only after this we should start sending the BCCH info and SACCH filling (the "actual" bootstrap of the RSL). For this to work, we need the Object Identity and Object Current State attributes (which is a WIP atm), but somehow it should be possible to separate the RSL bootstrap to RSL lapd only and RSL bcch info + sacch filling. I am unaware if the above separation is possible with the current codebase, but if someone can shed some light on this, that would be appreciated. Adding the Object Identity and Object Current State will also allow us to detect the actual state changes of various BTS objects (mostly the TRX), and we can also use the BTS_CHA_ADM_STATE to actually lock/unlock TRXes, so we dont need to fake the 12.21 state anymore. Regards, Csaba

Looking for BS11 mounting plates

by Alexander Huemer

Hi! I am in possession of a pair of Siemens BS11 mounting plates and am looking for a second pair. A photo of the plates is attached. Since - I believe - most people who play with such basestations do not mount them to a wall or pole, my hope is that some unused ones are floating around somewhere. Thanks, -Alex^Wblackbit

issues about csfb

by Masumeh Sadat Tohidi

Hello. I have tested CSFB on several phones in different situations. Calls from 4G to 2G are always established, but calls from 2G to 4G and from 4G to 4G are not always successful (sometimes they connect, and sometimes they do not). For this test, the phone's location relative to my USRP antennas is fixed. It is noteworthy that I have set the 4G neighbor in Osmo-BSC, as well as the 2G ARFCN information in SIB7. I attched log file and pcap of osmo system. osmo system ip:192.168.75.192 srsran_4G ip:192.168.75.185 open5gs ip:192.168.75.181 I would be very grateful if anyone with experience in this field could help me.
