20130017848 | SMS ROUTING - Mobile terminals are operated in a mobile telecommunications system such as GSM routing data messages such as SMS messages to a destination address via a selected of plural routing centers. A terminal receives user generated data defining an outgoing message and generates a first data field containing a first routing center address, a second data field containing the destination address, and a third data field containing the user generated data. The terminal traps the outgoing message and compares the first routing center address and a second routing center address, determined by a system administrator, stored in a memory the user cannot write-access. If the addresses differ, the first routing center address is replaced by the second routing center address in the data field and the outgoing message is routed via a second routing center with the second routing center address. The administrator thereby controls message routing. | 01-17-2013 |
