Run background service immediately on registration

I have implemented a background service that sends some data to server. But the service is only triggered after the trigger is fired. I want the service to fire immediately as and when its registered. I have tried

• DeviceTrigger
• LocationTrigger
• SystemTrigger(Internet available/Timezone-changed)
• MaintenanceTrigger

but they all are fired when their conditions are met as documented. Can any one have any idea how to get this work, btw I'm on windows phone 8.1 and C++.

PS. I just want my service to get triggered as it is registered.
