Apparatus and method for giving notification of a multimedia broadcast/multicast service while considering a transmission mode in a mobile communication system

摘要

An apparatus in a mobile communication system for providing a multimedia broadcast/multicast service (MBMS) and a method for giving notification of an MBMS service while considering transmission mode are provided. A controlling radio network controller (CRNC) sends, to a serving radio network controller (SRNC), transmission mode information indicating point-to-point (PTP), point-to-multipoint (PTM), or "Not provide" cell by cell. The SRNC determines service notification on the basis of the transmission mode information. The CRNC minimizes a signaling load on an Iur interface when sending, to the SRNC, the transmission mode information suitable for each cell.
