windows mobile get CellID

Programmatically getting the CellID from your Windows Mobile phone

he said..

I don’t know how the FindMe app is implemented, but after a little bit of playing tonight, it seems fairly easy to grab something similar to the “Cell” string they are using from the RIL_GetCellTowerInfo function in the Radio Interface Layer (RIL) API.

1. Call RIL_Initialize to get a RIL handle
2. Call RIL_GetCellTowerInfo to get the information about the cell tower the phone is connected to

   The “Cell” string that FindMe displays seems to be a combination of the dwCellID, dwLocationAreaCode and dwMobileCountryCode fields

3. Call RIL_Deinitialize to release the RIL handle

and a code.. just try next week..

using System;
using System.Threading;
using System.Runtime.InteropServices;

namespace CellId
{
public class RIL
{
// string used to store the CellID string
private static string celltowerinfo = "";

/*
* Uses RIL to get CellID from the phone.
*/
public static string GetCellTowerInfo()
{
// initialise handles
IntPtr hRil = IntPtr.Zero;
IntPtr hRes = IntPtr.Zero;

// initialise result
celltowerinfo = "";

// initialise RIL
hRes = RIL_Initialize(1, // RIL port 1
new RILRESULTCALLBACK(rilResultCallback), // function to call with result
null, // function to call with notify
0, // classes of notification to enable
0, // RIL parameters
out hRil); // RIL handle returned

if (hRes != IntPtr.Zero)
{
return "Failed to initialize RIL";
}

// initialised successfully

// use RIL to get cell tower info with the RIL handle just created
hRes = RIL_GetCellTowerInfo(hRil);

// wait for cell tower info to be returned
waithandle.WaitOne();

// finished - release the RIL handle
RIL_Deinitialize(hRil);

// return the result from GetCellTowerInfo
return celltowerinfo;
}


// event used to notify user function that a response has
// been received from RIL
private static AutoResetEvent waithandle = new AutoResetEvent(false);


public static void rilResultCallback(uint dwCode,
IntPtr hrCmdID,
IntPtr lpData,
uint cbData,
uint dwParam)
{
// create empty structure to store cell tower info in
RILCELLTOWERINFO rilCellTowerInfo = new RILCELLTOWERINFO();

// copy result returned from RIL into structure
Marshal.PtrToStructure(lpData, rilCellTowerInfo);

// get the bits out of the RIL cell tower response that we want
celltowerinfo = rilCellTowerInfo.dwCellID + "-" +
rilCellTowerInfo.dwLocationAreaCode + "-" +
rilCellTowerInfo.dwMobileCountryCode;

// notify caller function that we have a result
waithandle.Set();
}
