MBMS method and apparatus for UMTS network
First Claim
1. A method of providing a point-to-multipoint service to a mobile terminal, the method comprising:
- receiving, from a second network controller when the mobile terminal moves from a first cell controlled by a first network controller to a second cell controlled by the second network controller, information indicating one of a point-to-point and point-to-multipoint communication mode supported by the second network controller; and
determining whether to transmit point-to-multipoint service data from the first network controller to the second network controller according to the received information.

Abstract
A method and apparatus for providing a point-to-multipoint service to a mobile terminal that moves from an area controlled by a first radio network controller (RNC) to an area controlled by a second radio network controller is provided. Information regarding a transmission mode status of the second RNC is utilized by the first RNC to determine if it is necessary to transmit MBMS data to the second RNC. MBMS data is transmitted from the first RNC to the second RNC only if the transmission status of the second RNC is point-to-point, thereby preventing unnecessary data transmission between the first RNC and second RNC and the enhancing the efficiency of the radio resources between the second RNC and the mobile terminal.
