Supporting dynamic IP addresses for wireless push services in cellular networks

The 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 (packet data protocol) context activation for static IP users during wireless location-aware and content aware push application delivery over the packet-switched wireless core network. The proposed method is based on protection and mobile user activity procedures, SMS service, and a new signaling mechanism to forward HLR (home location register) based flags to the WAP/directory server.
