20110086649Methodology for Traffic Control Based on Cross-Carriers Short Message (SMS) Application - Method of traffic control for cross-carrier SMS application, the major feature is to set different RAM realization strategies and achieve traffic control over the operational process of SMS by setting different limits for different carriers including the overall limit, total traffic limit and individual user's traffic limit; 1) Different carriers adopt different overall limits: traffic limit is set for different carriers in RAM, based on differences of the receiving number's properties. 2) Overall Traffic Limit: It is achieved by setting a simple overall traffic limit. When the time limit is reached for sending the message, all sending modules will temporarily suspend the sending procedure for a certain time until the defined time. 3) The strategy of using RAM to restrict individual user's network traffic: RAM can be achieved through HASH MAP. 4) The implementation of RAM strategy: using RAM in accordance with different traffic control requirements. 5) In order to achieve “time-out processing”, the system also add the “time-out sub thread”. Through this thread, the message will be transferred to the “time-out processing module” automatically in the case of timeout.04-14-2011
