NCC alocation

I'm having this question about NCC allocation. Is this unique for an operator inside a country? And how it goes if you travel abroad ? (Will the phone look for a network with the same NCC at the begining?) After that it will look at sysinfo and the other stuff but I was wondering how it goes at power up? Thanks.

CCCH question
by eisencah eisenach 03 Apr '11

Hi. In its current stage osmocom makes full use of CCCH-CONF and BS-AG-BLK_RES fields of CCCH description? If a block is reserved for access grant it won't be used on paging? Is there anyway of calling "gsm48_sysinfo_dump" to print on the console? Cheers, Mihai.

> But it is also possible to have two layer 3 messages in the same LAPDm frame (one ending and one starting for example)? no, you can't! it could be possible, since there is a length field in every layer 2 frame, but there is nothing in the specs about it.

another compiling problem (beginner)

Hi all, Sorry for bothering with another compiling problem. I had the following error while compiling osmocom-bb: configure:3246: arm-elf-gcc -Os -ffunction-sections -I/home/loretta/osmocom- bb/src/target/firmware/include -nostartfiles -nodefaultlibs conftest.c >&5 conftest.c: In function `main': conftest.c:15: warning: initialization makes pointer from integer without a cast /home/loretta/install/gnuarm-3.4.3/bin/../lib/gcc/arm-elf/3.4.3/../../../.. /arm-elf/bin/ld: warning: cannot find entry symbol _start; defaulting to 00008000 /tmp/ccgIuxoW.o(.text.main+0x14): In function `main': : undefined reference to `fopen' /tmp/ccgIuxoW.o(.text.main+0x1c): In function `main': : undefined reference to `ferror' /tmp/ccgIuxoW.o(.text.main+0x30): In function `main': : undefined reference to `fclose' collect2: ld returned 1 exit status configure:3250: $? = 1 configure:3287: result: configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "libosmocore" | #define PACKAGE_TARNAME "libosmocore" | #define PACKAGE_VERSION "UNKNOWN" | #define PACKAGE_STRING "libosmocore UNKNOWN" | #define PACKAGE_BUGREPORT "openbsc-devel(a)lists.openbsc.org" | #define PACKAGE_URL "" | #define PACKAGE "libosmocore" | #define VERSION "UNKNOWN" | /* end confdefs.h. */ | #include <stdio.h> | int | main () | { | FILE *f = fopen ("conftest.out", "w"); | return ferror (f) || fclose (f) != 0; | | ; | return 0; | } after hours of trying to understand how to fix this, I figured out that without the option -nodefaultlibs everything run smoothly. Now, the problem is that I do not understand much of what is going on and I wonder, do I need that option and hence should look for a different way of fixing the problem? Thanks for your help, Loretta

Thanks. But it is also possible to have two layer 3 messages in the same LAPDm frame (one ending and one starting for example)?

Hi everyone. One question : are there any layer 3 messages that would span across multiple LAPDm frames? Or are they chosen such that this never happens? Thanks, Mihai.
