Group subscriber number management system for a group messaging service

摘要

A method for managing group subscriber numbers in a group messaging device reduces the required number of group subscriber numbers used by the messaging service. The required number of group subscriber numbers is equal to the total number of groups in which a user is permitted to be a member and not the total number of groups of users in the system.
