Hi Harald,
You once posted a pcap of a "Network Listen" process of the ip.access
nanoBTS, I think.
If I anlyze the traffic, I can't find any messages leading to "Network
Listen" activities.
According to the nanobts product spec. "Network Listen" is an ip.access
specific message, so when looking at 0xfe (ipaccess) I only see the
Ping/Pong messages.
In GSM 12.21 I couldn't find something about scanning or listening for
other ARFCNs. But it's possible I haven't read the spec well or didn't
understand completely.
Any idea's?
