摘要

A method and system for sending short message, and group main switchboard are provided in the invention. Wherein, users in group can use "special service number + ext." to send short message each other, and users in the group can send short message to the user outside the group in the way of using "special service number + called user number", however, the user outside the group can directly send short message to the user in the group in the way of using "group main switchboard number + ext. ". The users in the group can perform the communication between the user inside and outside the group by use of pseudo number to protect the number privacy of user in the group, and that breaks through the limit of using pseudo number to communicate only in VPMN; the user in the group uses "group main switch board number + ext. " to communicate short message with the user outside the group, that can establish a identical external service window for the group and built up identical external form of the group; the translation between calling and called number can avoid the interaction with Intelligence Network(IN) of short message, and the concussion between service and IN can be reduced.
