Abstract: A method and apparatus are provided for the secure delivery of converged services to users of wireless devices in a wireless environment. An application layer broker is position between the user devices and the application server to provide an indirect coupling between the enterprise application server and the wireless user devices. The application layer broker links the wireless environment to the enterprise application server through an event triggered content delivery mechanism without providing a direct link between the wireless user device and the enterprise application server. Delivered content can only be accessed by the intended user and the authorized device. The application layer broker provides adaptation to various user devices and the various capabilities associated with each user device. Wireless devices can be upgraded independently from upgrades to the application server.

Abstract: The present invention is a system and method to improve the reliability and performance of existing enterprise IP networks which have dual-homed (or multi-homed) network architectures. In one aspect of the invention packets related to a selected category of transmission (e.g., VoIP) are duplicated at an edge router and sent over both (multiple) service providers. After traversing the service provider networks, only the first-to-arrive packets are kept and the later-arriving copies are discarded. In so doing, the result is better protection against node failures, link failures, and packet errors, and also better QoS performance under normal (fault-free) operation.

Abstract: Techniques are disclosed for controlling interaction between an enterprise application and a mobile client device in a communication system. Push content is generated in a wireless secure server or other type of server, responsive to information received in the wireless secure server from the enterprise application. The push content is deliverable from the wireless secure server to the mobile client device over a wireless network. The wireless secure server receives from the mobile client device, responsive to the push content, a request for additional information identifiable at least in part by the push content. The additional information is deliverable from the server to the mobile client device over the wireless network.
