1. Remote Interaction Through IP Networks.
|
|
|
|
Remote interactions through interfaces is generally a "remote network
|

interaction" and requires compliance with Section 13 of the AGPLv3.
|
|
However, remote interactions other than the GSM air interface are permitted
|
|
without requiring compliance with Section 13 of the AGPLv3. This exemption
|
|
of interactions with interfaces other than the GSM air interface from the
|
|
requirements of Section 13 is an additional permission granted to you.
|
|
|
|
2. GSM "A5" cipher stream generation libraries
|
|
|
|
Notwithstanding any other provision of this License, you have permission to
|
|
link the Program with GSM "A5" cipher-stream generation libraries provided
|
|
under any license that allows redistribution of those libraries in binary
|
|
form, provided that the function of any such library is limited to the
|
|
generation of cipher-stream bits. This permission to link to certain
|
|
libraries is an additional permission granted to you.

RECOMMENDATIONS
|
|
|
|
How to comply with Section 13 of the AGPLv3 license.
|
|
|
|
OpenBTS includes an implementation of the GSM network cellular air interface,
|
|
as well as other interfaces to IP networks. Range Networks believes that
|
|
interaction of cellular handsets with the OpenBTS software is considered
|
|
"remote network interaction" for the purposes of the AGPLv3 and cellular
|
|
users have the right to obtain source code as provided in Section 13 of
|
|
AGPLv3 except for the additional permissions granted above.
|
|
|
|
The recommended method for compliance with Section 13 of the AGPLv3 license
|
|
for OpenBTS is to deliver a text message to each handset that attaches to the
|
|
OpenBTS cellular network. At a minimum, that text message should include the
|
|
string "OpenBTS AGPLv3" and a URL that can be used to access the OpenBTS
|
|
source code. This message need not be delivered to handsets that are denied
|
|
registration with the network, since those handsets have been denied service.
|
|
|
|
In OpenBTS 2.6 and above, such text messages can be delivered with the
|
|
"Welcome Message" feature. See OpenBTS documentation for more information
|
|
on the use of this feature for AGPLv3 compliance.
