This paper details the wireless location-aware and content aware push application delivery over the packet-switched wireless core network. The directory server, which is deployed besides the WAP server in order to support the push applications by storing the user profile, IMSI and user IP address, requires static IP addressing to support such 3G applications. In current system, the incoming IP packets destined for dynamic IP users are discarded at the GGSN level. This paper introduces a methodology to provide push services to dynamic IP addressed-mobile users in 2.5G/3G networks, and minimize the unsuccessful-network-requested PDP context activation for static IP users. The proposed method is based on the protection and mobile user activity procedures, SMS service, and a new signaling mechanism to forward the HLR-based flags to the WAP/directory server.
