The present invention relates to forwarding of text messages, for example, the Short Message Service (SMS) available for cellular radio telephone networks during peak traffic periods. The invention reuses the existed infrastructure and discovers a new method to forward text messages within a text messaging system. With this invention, more messages can be sent to SMSC in the same bandwidth during peak traffic periods. Additionally, the merge can save lots of system storage in SMSC. The idea does not need operators to increase the capacity of SS7 links, SMSC and its system storage, which really helps mobile operators to reduce costs and improve their networks' quality in order to maintain customer satisfication during peak traffic periods.

SMS (Short Message Service) is a service that enables a subscriber to send text messages to, and receive text messages from Mobile Stations(MS) in GSM cellular radio telephone networks. The service makes use of an SMSC(Short Message Service Centre),

which acts as a store-and-forward system for short messages

. The


and transports short messages between SMSC and MS. In contrast to other existing text-message transmission services, the service elements are designed to provide guaranteed delivery of text messages to the destination. When a mobile station is switched off or not within range, then the text message is stored until the mobile station becomes available.

wireless network provides the mechanisms required to find the destination station

A distinguishing characteristic of the service is that an

active mobile handset is able to receive or submit a short message at any time , independent of whether a voice or data call is in progress.

Additionally, SMS

supports several input mechanisms that allow interconnection with different message sources and destinations.

We consider the GSM network system under heavy traffic during holiday period , in

                                           , maybe modify a small quantity of words in the messages and then forward them to other subscribers . The subscribers almost always complain about the operator service because they

which several hundred million subscribers receive SMS messages

will have to wait long time before they finally send the forwarded messages


In the above scenario, there exists three kinds of bottleneck. The first bottleneck is self-imposed. Operators are limited by their current SS7 infrastructure capacity for SMS messages. Secondly low-performance SMSC that can only deliver a few hundred short messages per second are obviously bottleneck. Lastly in SMSC system, small-capacity storage that can only store billions of text messages are also bottleneck.

Currently there're known solution for operators to resolve the problem. Operators may need to increase their SS7 capacity so that a high-performance SMSC can run at an optimal level. Operators either need to make a major upgrade to a high-performance system (1500 Msg/sec or more) or they can increase throughput by the addition of more stand-alone systems. Operators need to add some extra system storage for SMSC.

The solution is not good enough because operators have to invest much time and money in increasing the capacity of SS7 links, SMSC and its system storage to meet the large amonts of forwarding requirement during peak traffic periods . Especially, the investment will be wasted during common traffic periods.

The idea is raised by the investigation on the subscribers ' common experience during peak...
