Push selling—Multicast messages to wireless devices based on the publish/subscribe model

摘要

Push technology automates the information delivery process by not requiring users to request for the information they need. Wireless has experienced explosive growth in recent years, and “push” will be the predominant wireless service delivery paradigm of the future. A wide variety of services, alerts and messages, such as promotional content, will be delivered to consumers’ phones or PDA. However, to push information to a wireless device can be a challenge because of the problem of intermittent communication links and resource constraints on wireless devices as well as limited bandwidth. This paper explores an efficient multicasting mechanism that “pushes” pre-specified information to groups of wireless devices. The mechanism operates with limited bandwidth and also overcomes the connectivity problem. Based on the above concept, we have designed and implemented a system to multicast sales information via wireless technology. The system is message-oriented and JMS compliant.
