<p>A method for implementing Internet protocol OP) Multicasting service in the mobile communication system, in which the said mobile communication system comprises a gateway GPRS support node (GGSN) and a domain name system (DNS). The said method is characterized in that comprises the steps of: receiving a access point name (APN) and a plurality of mobile station integrated service digital network (MSISDN) numbers by the said GGSN; creating the said APN policy, and adding the tag information of the said APN into the APN tag list of the said GGSN; adding a record including the IP addresses of the said APN and the said GGSN into the database of the said DNS; creating a data structure in the said GGSN, for storing the said APN and the said a plurality of MSISDN number, and in the data structure, retaining each of MSISDN numbers a storage space for storing the address of packet data protocol (PDP), so that the information stored in the said data structure identifies a newly created user group. The present invention provides a kind of new point-to-point data service with much attraction for the mobile data user.</p> |
