Method for connecting broadcasting or multicast service between network elements in mobile communication system

The present invention European IMT-2000 system, while ensuring the mobility of a mobile station in a mobile communication system such as UMTS (Universal Mobile Telecommunications System) relates to a method for providing smoothly a broadcast and multicast services, in particular mobile station in one network element when moving to another network element, to a frequent signaling messages transmitted to prevent an increase in network loads a mobile communication system between the network elements in the broadcast or multicast service connection due to the method. Mobile communication system, the network element between the broadcast or multicast service connection method in accordance with the present invention, in a mobile communication system that provides for the terminal broadcast or multicast service, the terminal is in a network element (the first network element) when moving to another network element (second network element), sending a service connection request message including information about the participants is the terminal service from the first network element to the second network element; And it is characterized by configured by comprising performing a service connection procedure of the terminal with respect to the service included in the information regarding the service from the second network element.
