Embodiment Construction
[0022] In order to illustrate the implementation steps of the present invention clearly and in detail, some specific embodiments of the present invention are given below. In these specific embodiments, it is assumed that the multicast service is the MBMS service defined in the 3GPP network, and the device for providing the multimedia broadcast multicast service is obtained by upgrading the broadcast and multicast service center (BM-SC) in the existing 3GPP network of. However, it should be noted that this is only given as an example, and the application of the present invention is not limited to this situation, but is also applicable to the BCMCS service defined in the 3GPP2 network or the multicast service in other non- The situation of the corresponding service defined in the 3GPP network (such as the WiMAX network). Therefore, the user terminal can also receive the BCMCS service defined in 3GPP2 in the non-3GPP2 network, or can also receive the multicast service defined in...

The invention provides a device for supplying a MBMS (Multimedia Broadcast Multicast Service) in a heterogeneous network, the heterogeneous network adopting the device as well a switching method for a user terminal accepting the MBMS in the heterogeneous network. The heterogeneous network comprises multiple networks which are provided with different network structures and adopt different communication protocols. The device for supplying the MBMS comprises a signaling receiving unit, a signaling generating and transmitting unit and a MBMS data supplying unit, wherein the signaling receiving unit is used for receiving a MBMS carrying establishing request from a gateway of the network to which the user terminal is switched, the signaling generating and transmitting unit is used for generating and transmitting control signaling which is used for establishing the MBMS carrying between the device and the gateway; and the MBMS data supplying unit is used for supplying synchronous MBMS data on the established MBMS carrying.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a device for providing Multimedia Broadcast Multicast Service (MBMS, Multimedia Broadcast Multicast Service), a heterogeneous network using the device, and a user terminal receiving MBMS service in the heterogeneous network method of switching. Background technique [0002] With the increasing demand for wireless communication, the provision of multimedia services by wireless communication has attracted more and more attention. Applications such as mobile TV and video conference calls will be popularized in the next few years. [0003] For high-speed and high-quality-of-service multimedia transmission, unicast can no longer meet the requirements. In this case, multicasting and broadcasting are considered to be the most effective ways to improve spectrum utilization. For this reason, both 3GPP and 3GPP2 have defined multimedia broadcast multicast services,...
