METHOD, SYSTEM AND VPBX FOR SENDING SHORT MESSAGES

摘要

A method, a system and a Virtual Private Branch Exchange (VPBX) for sending short messages, wherein users in a group can send short messages to each other by using a special service number plus an extension number; users in a group can send short messages to users outside the group by entering the special service number plus a called number; and users outside a group can send short messages to users in the group by using the main number of the group plus an extension number. Short messages can be sent between users in the same group or between users in the group and users outside the group by using pseudo numbers, this protects the privacy of the numbers of users in a group and breaks through the limitation that only users in the same VPMN group can use pseudo numbers to send short messages to each other; users in a group communicate with users outside the group through short messages using the main number of the group plus an extension number, a unified service window is open to external users and a good image is set up for the group. In addition, the interaction with the intelligent network for the translation of the calling number and the called number of a short message is avoided, thus reducing the impact of the service system on the intelligent network.
