Multicast resource distribution and transmission method for scalable video in system with multiple base stations

The invention discloses a multicast resource distribution and transmission method for a scalable video in a system with multiple base stations. The multicast resource distribution and transmission method is characterized by comprising the following steps that: (1), mobile equipment in one cellular cell receives data transmitted from different base stations; (2), a video flow is divided into a base layer and an enhancement layer; (3), a base station control centre selects one proper transmission base station for each video layer and determines which modulation coding manners are used; and (4), the multiple base stations transmit the video layers according to the appointed modulation coding manners and calculate the total number of the video layers received by the mobile equipment in the system and the utility value of the system. According to the invention, spectrum resources are effectively utilized; the utility value of the whole system is increased; the overall throughput of a network environment is effecti
