ABSTRACT:
A method and apparatus for informing terminals in a UMTS regarding state information of an MBMS in order to prevent terminals from requesting a service that cannot be provided in a cell in which it is newly located. The mobile communication network informs the terminals about its service provision state for a particular MBMS service being provided, and the terminals operate in accordance with this service provision state information to minimize unnecessary operations of the terminal and unnecessary signaling and waste of radio resources.
