Non-VOIP Spam Detection Call App”

Hi……I am working on "Non-VOIP Spam Detection Call App”. I Hope you will provide the best solution for the below mentioned query.


Query:

1) let say if the app is in suspended mode and I want to update the “iPhone App’s Local Database” whenever there is a change in “Server Side Database” ?

(or)

2) I want to activate the app in the background with some sort of notification, Similar to “PushKit Notification in VOIP Calling”(I cannot use “PushKit Notification because it is for VOIP Calling and cannot use “Silent Notification” because we cannot trigger not more than two or three notifications per hour)?
