A MESSAGE ROUTER FOR CONCATENATED SMS

摘要

A message router comprises a message controller with service logic functions, and a state database. It receives and processes message segments, maintains state of single and concatenated messages, and applies services to the messages. A routing and discrimination engine accesses a selected state database among an associated database and distributed state databases. The controller operates in a transparent-relay mode in which a message is relayed to a network element and the response from the network element is returned directly to an originator. The relaying may be performed using SCCP relaying. The controller can operate in a transparent- proxy mode in which it generates a fresh message and sends it to a network element and receives the response from the network element, and in turn returns a response to the originator.
