Abstract
A network configuration capable of prioritizing and categorizing paging messages using a deep packet inspection (“DPI”) idle mode agent (“IMA”) is disclosed. Upon receiving downstream traffic addressing to end user (“EU”) equipment in a communication network, the process, in one embodiment, is able to identify forwarding action by comparing the downstream traffic with content of predefined list of a forwarding table. The downstream traffic is directed to an inline DPI agent or DPI IMA if the EU equipment is in idle mode in accordance with comparison between the downstream traffic and the forwarding table. The process categorizes the downstream traffic to a high priority paging category when the downstream traffic matches with one of legitimate push applications stored in a list of legitimate push applications.
