A telecommunications system and method is disclosed for transmitting and receiving short messages between a Mobile Station (MS) within an Internet Protocol (IP) based cellular network and a web site on the Internet. Each web site that the MS has access to contains an Application Program (AP). To retrieve the information, the MS within an IP-based cellular network originates a short message towards the AP associated with the web site using a pre-assigned E.164 number for the AP. When the short message reaches a Mobile Switching Center (MSC), an Application Manager (AM) within the MSC intercepts the short message and translates the E.164 number into an IP-address and port number for the AP. The AM extracts the data from the short-message, packs the data in an SMTP envelope and transmits it to the AP.

This invention relates to the design of a scaleable high performance multiservice network based on programmable transport. A meshed network with dynamically-adjustable link capacities and nodes which provide data packing into "containers" for transport is proposed. A ring-based network, exchanging data containers among its nodes, is the preferred implementation, due to its flexibility, maintainability, and high reliability. With lossless rings, the quality of service is controlled solely by the origin and destination nodes, without any interference from other data streams. Flexible programmable transport greatly improves the performance, simplifies the controls, and facilitates scaleability. The concept is a departure from classical network thinking. By reducing the complexity of the network core, an economical, reliable, and manageable network with feature-rich edge nodes can be realized. An architecture with recursive ring-based structures provides a high degree of flexibility in bandwidth allocation and is compatible with current transport networks and future all-optical networks.
