    • The invention relates to a mechanism for performing multicast transmission in a cellular network. In order to enable establishment of resources only in cells containing members of the multicast group and to avoid congestion on the uplink channel, a multicast service notification is transmitted to mobile stations, thereby informing members of the multicast group of an upcoming multicast session. The moment for a response to said multicast service notification is selected in the mobile stations and a presence report is sent from at least one of said mobile stations at the response moment of said at least one mobile station. The presence report or reports are received within a radio access network, and radio resources are established for multicast transmission in a cell of the cellular network when the presence report(s) received in said cell meet(s) predetermined criteria.
    • 本发明涉及用于在蜂窝网络中执行多播传输的机制。 为了仅在包含多播组的成员的小区中建立资源,并且为了避免上行链路信道的拥塞,向移动台发送组播业务通知,从而向组播组的成员通知即将到来的组播会话。 在移动台中选择响应于所述多播服务通知的时刻,并且在所述至少一个移动台的响应时刻,从至少一个所述移动站发送存在报告。 在无线电接入网络内接收存在报告或报告,并且当在所述小区中接收到的存在报告满足预定标准时,为蜂窝网络的小区中的多播传输建立无线电资源。

    • The invention relates to a network element (23) for a radio access network (22) of a cellular network supporting the transmission of multicast and broadcast multimedia services via a radio interface Uu to user equipment (25), which network element (23) comprises radio interface protocols associated to different protocol layers including a data link layer (layer 2). In order to enable such transmissions, it is proposed that the data link layer comprises a dedicated multicast broadcast multimedia control sublayer (L2/MBMC) for a multicast broadcast multimedia control protocol (MBMC). The MBMC is to adapt multicast and broadcast multimedia services, originating from a core network of said cellular network, for transmission in the radio interface Uu. The invention equally relates to a corresponding radio access network, to a corresponding cellular network, to a corresponding user equipment, to a corresponding radio access based communication system, and to a corresponding method.
    • 本发明涉及一种蜂窝网络的无线电接入网络(22)的网络元件(23),该蜂窝网络支持经由无线电接口Uu向用户设备(25)发送多播和广播多媒体服务,该网络元件(23)包括 与包括数据链路层(层2)的不同协议层相关联的无线电接口协议。 为了实现这种传输,建议数据链路层包括用于组播广播多媒体控制协议(MBMC)的专用多播广播多媒体控制子层(L2 / MBMC)。 MBMC用于适应来自所述蜂窝网络的核心网络的组播和广播多媒体业务,用于无线电接口Uu中的传输。 本发明同样涉及对应的无线电接入网络,对应的蜂窝网络,对应的用户设备,到相应的基于无线电接入的通信系统以及相应的方法。
