Method for transmitting short message

Abstract

The invention relates to a method for sending message. Wherein, the internal user can uses the combination between special number and extension number to communicate the message; and uses the combination between special number and called number to send message to external user; and the external user can use the combination between central number and extension number to send message to the internal user; the internal user can uses false number to communicate message between internal and external users, to keep the privacy of internal number. And the internal users the combination between central number and extension number to communicate message with external user, to form consistent service interface. The translation of message calling and called numbers can avoid interacting with intelligent network, to reduce the impact.

Description

technical field [0001] The invention relates to a method for sending short messages, in particular to a method for sending short messages by internal and external users of a group on the basis of a VPN network, and belongs to the technical field of electric communication. Background technique [0002] VPN (Virtual Private Network): virtual private network, mainly based on the technology of virtualizing a tunnel on the public network at the network layer, as a transmission line technology, providing a secure remote access to the private network within the enterprise through the public network connection method. [0003] The method of sending a short message using a VPN short number (a short number that communicates with each other in the VPN network, with fewer digits than the real terminal number) is as follows: [0004] 1. The caller uses the VPN short number to send a short message to the Short Message Service Center (Short Message Service Center, SMSC) via the Mobile Swi...

AI Technical Summary

Problems solved by technology

[0009] 1. VPN short messages can only be sent between users in the VPN group, and group users cannot use VPN short numbers to send short messages to each other with users outside the VPN network, so it cannot meet the needs of the group and its users to communicate with the outside world;

[0010] 2. The translation of VPN long and short numbers is completed by the intelligent network, which increases the burden on the intelligent network, especially when the short message traffic is large, it will have an impact on the intelligent network
