You can manually trigger the heartbeat to keep the connection alive by the following code. Some network routers will automatically kill the idle socket connections if it is idle for a particular time period (sometimes 5 minutes). Execute the code in every 5 minute so that the connection will be re-established if it is closed. But, obviously reducing the interval will consume bit more battery (I don't know how much it is relevant here because nowadays the smart phones come up with high mAh battery).

getApplicationContext().sendBroadcast(new Intent("com.google.android.intent.action.GTALK_HEARTBEAT"));
getApplicationContext().sendBroadcast(new Intent("com.google.android.intent.action.MCS_HEARTBEAT"));
