how to retrieve cellid from a mobile phone

hi,
i am final year student doing my project on Location Based System .
basically we retrieve the cell id and put it onto a map.
we have got some sample codes with us but when we compile it we encounter with lots of compilation errors.

There are 2 files
1. cellid.cpp
2. System Manager.

[B]CELLID.CPP[/B]

The required header files in this are etelbsm.h which we alredy have ...

thank you

There are a number of threads about getting the GSM Cell Id. The proper way also depends on the SDK you use, and you have not named one.
Use the search facility anyway.

If you want to retrieve cellid for 2nd edition, go thru the post:
[url]http://discussion.forum.nokia.com/forum/showthread.php?t=19693[/url]

if you want to do this for 3rd edition phones you can use CTelephony.

hi ,
this is another way to retrive cell id.

it help u to give the cell id .

[CODE]
void CGetimeiexContainer::GetImei(TDes &aImei)
{
#ifndef __WINS__
RTelServer* ts=new RTelServer;
ts->Connect();
RTelServer::TPhoneInfo pi;
ts->GetPhoneInfo(0,pi);

RBasicGsmPhone* ph=new RBasicGsmPhone;
ph->Open(*ts,pi.iName);
ph->Initialise();

RBasicGsmPhone::TId id;
ph->GetGsmPhoneId(id);

aImei=id.iSerialNumber;

delete ph;

ts->Close();
delete ts;
#else
aImei=_L("1234567890ABCDEF");
#endif

}

[/CODE]

hi ,

this link is also help to give cell id.

hi ,
actually i went through the sites u suggested .but the problem is that in the code we have some thing called Ctelephony which is not defines in our SDK .
And also the SDK we use is 6.1 and 7.0 for series 60 phones.
we have downloaded the file called Mobinfo 3rd Party Telephone Line whic contains functions to get the cell id and all.
but the problem is that the classes defined in mobinfo can be used on UIQ phones only.

can u guys recommend me any solution.

the basic aim of my project is to retrieve the cellid of the base station and use it to put it on a local map ..in short to make a Location Based System using the help of the cellid ..

[QUOTE=aloke]hi ,
we have downloaded the file called Mobinfo 3rd Party Telephone Line whic contains functions to get the cell id and all.
[/QUOTE]

MobInfo API can be used even in S60 Phones.
I have used them and they work perfectly fine.

Regards.

hi tina,
the thing is that in my code as mentioned in the earlier post we have something called Ctelephony which is only available in later versions of Symbian OS ..
the Ctelephony class is not available in series 60 phone SDK therefore everythting changes.

we haveto download the later version of the SDK.. or is there any other method to get round this problem.

thanx

Hi Aloke,

Sorry for the delayed response.
CTelephony is only available for S60 3rd Edition.
If you want to use CTelephony you need to download the
3rd Edition SDK.

You can use MobInfo API for 2nd Edition if you want
to retrieve the cell id information.

Regards.

sorry for such a delay it thaught people had stop reading my post...
the thing is i have got a sample code called mobinfo test from a site.
the thing is that the code is written for UIQ thats is ericsson phones..
what i have done is changed all the Cqik to Eik ...

now the problem i face is in the .mmp file there is a file called qikctl.lib which is for UIQ. whenever i remove this lib and upudate the .mno file it comes back ......

THIS THE SITE FROM WHERE I FOUND THE CODE....
[url]http://developer.sonyericsson.com/site/global/techsupport/tipstrickscode/symbian/p_mobinfo_api_a_library_to_reach.jsp[/url]

This is the example of MobInfo Api usage in S60.

hi tina ,
i am actually a noobie to symbian c++. trying to learn it on my own as far as possible.
downloaded the hello world program u gave. the thing is that in the .RSS file there is pane which has the following contents:


RESOURCE MENU_PANE r_example_first_menu
{
items=
{
MENU_ITEM { command=ECancelRequestUI; txt="CANCEL Request"; },
MENU_ITEM { command=EGetIMSIUI; txt="EGetIMSI"; },
MENU_ITEM { command=EGetIMEIUI; txt="EGetIMEI"; },
MENU_ITEM { command=EGetOwnNumberUI; txt="EGetOwnNumber"; },
MENU_ITEM { command=EGetCurrentNetworkUI; txt="EGetCurrentNetwork"; },
MENU_ITEM { command=EGetHomeNetworkUI; txt="EGetHomeNetwork"; },
MENU_ITEM { command=EGetCellIdUI; txt="EGetCellId"; },
MENU_ITEM { command=ENotifyCellIdChangeUI; txt="ENotifyCellIdChange"; },
MENU_ITEM { command=EGetNetworkAvailabilityUI;txt="EGetNetworkAvailability"; },
MENU_ITEM { command=ENotifyNetworkAvailabilityChangeUI; txt="ENotifyNetworkAvailabilityChange"; },
MENU_ITEM { command=EGetBatteryChargeLevelUI; txt="EGetBatteryChargeLevel"; },
MENU_ITEM { command=ENotifyBatteryLevelChangeUI; txt="ENotifyBatteryLevelChange"; },
MENU_ITEM { command=EGetSignalStrengthLevelUI; txt="EGetSignalStrengthLevel"; },
MENU_ITEM { command=ENotifySignalStrengthLevelChangeUI; txt="ENotifySignalStrengthLevelChange"; },
MENU_ITEM { command=EEikCmdExit; txt="Close"; }
};
}


i am reffered the addison wesley book and in that they had written that MENU_PANE provides a various item in the menu list .
but i couldnt see any list like that.

and moreover why does the helloworld program requires cmobinfo.cpp file??..

thanx
bye!!!!!!!!!!!!

Hi Alok,

The function CMobInfo::IssueRequest(TMobInfoRequest aRequest)
in cmobinfo.cpp is the function which does the placing of requests for
retreiving the IMEI and stuff.

Adn actually there was some problem with this code because of which the menu
Options on LHS didnt appear.

You can integrate the mobinfo.h and mobinfo.cpp in your and use them like they are used in AppUi.cpp.

I presently dont have the modified code.

Hope this makes sense to you.

Regards.

Hi,

Attached is the working example using MobInfo API.
It will write the values into a file mobinfo.txt in c:\
I went through your code and found out that you are not familiar
with the Active Objects Framework.
I would suggest you to go through the active object framework before proceeding.

If you still face problems feel free to ask.

Regards,
Tina

i dunno how to send attchamnets over the forums!!!!!!
