AT-commands for the Siemens networkmonitor? - GSM-Forum

Mike.Joohsen · 03-05-2003, 14:45

Hi,

does anybody know which at-commands e.g. AT^SMONC,
AT+SMONC, AT^MONI, AT+MONI, AT^MONP or AT+MONP on
which Siemens phones are suitable to request the
network monitor informations???

There is a program on www.nobbi.com which can read
this informations from Siemens phones, but I cannot
find any information about these AT-commands for
Siemens GSM-phones.

The only information I found is for Siemens GSM-
data-terminals.

Any hints are welcome.

Regards
Mike

Programmes reading information like netmonitor, use following AT command:

AT+CBC Battery charge
AT+CSQ Output signal quality
AT+CPAS Query the telephone status
AT+COPS? and AT+CREG? - cell info

If you need more information about AT commands check this url:
http://www.traud.de/gsm/atex.htm

Best regards

Thank you for the info! I have tested these
commands. They work fine for Sagems and I
found them also in the Siemens documentation.

But there have to be additional commands
specially for Siemens phones! Nobbi's program
can read the frequencies and field strenghts
of the neighbouring cells!

Nobbi's program reads frequencies and field strengts behind help of command I passed You.
For example:
> at+creg?
+CGER: 0,1,"5E25","605F"
Cell ID = 605Fh = 24671
LAI = 5E25

> at+csq
+CSQ: 19,99
level:
19 = -75dBm
error rate:
99 - unknown

>at+cbc
CBC: 0,80

0 - is supplied from battery
80 - 80% charged

--description---
+CSQ: rssi,ber
Parameter:
rssi Reception level:
0 -113 dBm or less
1 -111 dBm
2-30 -109 to -53 dBm -109 + ((n -2)*2)
31 -51 dBm or more
99 Unknown
ber Bit error rate:
0-7 Like RXQUAL values from Table GSM 05.08 in Section 8.2.4
99 Unknown

+CBC: bcs,bcl
Parameter:
bcs 0 ME is supplied from battery
1 ME has battery but is not supplied from there
2 ME has no battery connected
3 Error
bc> 0 Battery is flat, but no more actions possible 1-100 charge in per cent

Hi,

maybe I am to stupid. Nobbi's program reads field strength, LAI, Cell-ID and batterie status with the standard AT commands. This works for nearly any phone (Sagem, Siemens, Nokia)

But I cannot see how nobbi's program is reading the additional(!) infos about the neighbouring cells, if (and only! if) you connect a Siemens phone. Any clue?

I cannot see any infos about the neighbouring cells in the given example. Right?

The AT^Mxxx commands for the Siemens-GSM data terminals seem not to work for Siemens phones.
(I tested for S45).

Maybe nobbi uses some special (not "AT"?) commands?

Best regards
Mike

Jester74 · 03-12-2003, 15:01

Sorry, you have right.

I have only non registered version Nobbi's NetMonitor aplication, which does no have function of monitoring neighbouring cells. Is possible that software used BFB protocol (begun by AT^SBFB command). I can find this commands, but I need registered version of Nobbi's software.
Best Regards

nrg · 03-13-2003, 09:15

It is simple to know what commands nobbi is using by some logging program comelite or advenced serial port monitor, just log the transmission and you'll know... I also don't have registrated version of this program so I can't do it myself

Mike.Joohsen · 03-13-2003, 11:58

Hi,

if somebody have the registered version and a Siemens phone he could use portmon to log the RS232 commands. Or he could use nobbi's mconfig program and set AT-Logging under Options1 (or write "debug=10000000000000011" in the monitor.ini File.) Nobbi's program will write a debug file.

I got a tip via email saying the program is using the sim toolkit command AT^SSTK to request the neighbouring cell infos form the phone. But I have no details yet.

Best regards
Mike

Mike.Joohsen · 03-13-2003, 15:12

Hi,

AT^SSTK (a Siemens command to use the SIM toolkit) seems the right way ;-) I looked at GSM TS 11.4. There is a SIM toolkit-command "PROVIDE LOCAL INFORMATION" which can request the network measurement results (besides LAI etc.). The coding description of the result is in TS 04.08.

But the coding of the request is totally cumbersome and the coding of the result is really "packed" :-(

best regards
Mike

Jester74 · 03-14-2003, 09:57

@Mike.Joohsen

You know syntaxes this command (PROVIDE LOCAL INFORMATION)?
I a bit experimented and I received such result:
- request:
AT^SSTK=50,0
>50524F56494445204C4F43414C20494E464F524D41
54494F4E(^Z) - this is string "PROVIDE LOCAL INFORMATION [ctrl-Z]" in hex format.
- response:
AT ^SSTK: 810300000082028281830136
OK

In Netmonitr in option SAT command are error messages:
1) ILLEGAL CMD
END OF SESION
SW: 90 00
2)
END OF SESSION
ILLEGAL CMD 30
Qual: 52
Resp: 36 00

I know that Proper response should be in format:
A B C D E
where:
A - Location Information tag (1 byte)
B - Length (X) of bytes following (1 byte)
C Mobile Country & Network Codes (MCC & MNC) (3 bytes)
D Location Area Code (LAC) (2 bytes)
E Cell Identity Value (Cell ID) (2 bytes)

You have some ideas?
It can you have description (with examples) command SAT?
Best regards

Mike.Joohsen · 03-14-2003, 16:43

I think the correct command description is in the GSM
standard TS 11.4. You can download the document for free
at www.etsi.org. (For decoding the network management
results you will also need the GSM standard TS 04.08,
chapter 10.5.2.20. It is also at www.etsi.org).

The request look like this:

1 D0 Proactive SIM command tag

3 81 command details tag
4 03 length
5 01 command number

1X = Add Card Reader X (0..7),
2Y = Channel Y (1..7)
11 82 destination: 82=ME, 02=Display, 03=Earpice

Example: (not sure, if the lenght in the "AT^SSTK=len,count" is
correct because my S45 seems to ignore this parameter :-)

Thanks a lot.
In fact, very difficult protocol (much comiled)

I will try implement netmonitor function based on Sim Toolkit in future version of gammu.

Woudu · 07-07-2003, 17:41

Hi,
I'm searching for an at-command to identify current cell from neighbouring cells. I 'm searching for a common information element for current and neighbour cells, which can be read from a mobile via at-commands. I can't find a command that fits. I can receive the LAC and CI of the current cell, but only BCCH of the ncells.
If the current cell changes, I have no information which new neighbour cell is my old current cell.
Any idea?
Is it possible with the BCCH channel list? Ii the current cell included in the list of Absolut Radio Frequency Channel Numbers?

Jester74 · 07-08-2003, 08:19

I am afraid , that you can read only channel number, reception level, NCC and BCC afterwards from neighbouring cells. To read LAC and CI cell has to be in use (It was been possible to read only from current cell).
BTW:
Do you use different model siemens mobile than c35i?
If so, you can check result of option
--siemensnetmonitor from current version of gammu?

Woudu · 07-08-2003, 14:21

I tried using gammu,
but it seems to have a problem decoding
'PROVIDE LOCAL INFORMATION' with command details 'Network Measurement results'.
I receive a correct reply from my mobile (Siemens ME45). But gammu exits with an error message:
[ERROR 16: Function not supported by phone.]
Nevertheless, this message does not contain any kind of cell identifiers in common with current and neighbouring cells.
Is it possible to get the BCCH-FREQ of the current cell?
In my application I store some data for every cell. I need this info for every ncell and my current cell.
When I read the information out of the database, I need an index or identifier of the cells, which is unique and available for current and neighbouring cells.
What can be used as an index?

I 'm searching for a common information element for current and neighbour cells, which can be read from a mobile via at-commands. I can't find a command that fits. I can receive the LAC and CI of the current cell, but only BCCH of the ncells. If the current cell changes, I have no information which new neighbour cell is my old current cell. Any idea? Is it possible with the BCCH channel list? Ii the current cell included in the list of Absolut Radio Frequency Channel Numbers?

I receive a correct reply from my mobile (Siemens ME45). But gammu exits with an error message: [ERROR 16: Function not supported by phone.] Nevertheless, this message does not contain any kind of cell identifiers in common with current and neighbouring cells. Is it possible to get the BCCH-FREQ of the current cell? In my application I store some data for every cell. I need this info for every ncell and my current cell. When I read the information out of the database, I need an index or identifier of the cells, which is unique and available for current and neighbouring cells. What can be used as an index?
