A method for determining a Single Frequency Network area, comprising: a Multi-cell/multicast Coordination Entity, MCE, determining a cell or cell cluster in which at least one User Equipment subscribing for a Broadcast Multicast Service is present; the MCE determining any cell or cell cluster which has no User Equipment subscribing for the Broadcast Multicast Service and is neighboring to the cell or cell cluster in which the at least one User Equipment subscribing for the Broadcast Multicast Service is present, as an auxiliary cell or cell cluster; and the MCE selecting any of the auxiliary cells or cell clusters that satisfies a preset condition, and determining both the selected auxiliary cells or cell clusters and the determined cell or cell cluster in which the User Equipment subscribing for the Broadcast Multicast Service is present as a Single Frequency Network area, characterized in that: the MCE selecting any of the auxiliary cells or cell clusters that satisfies a preset condition comprises: the MCE selecting any of the auxiliary cells or cell clusters so that neighboring cells or cell clusters of the selected auxiliary cell or cell cluster comprise cells or cell clusters that have at least one User Equipment subscribing for the Broadcast Multicast Service and the number of the neighboring cells or cell clusters of the selected auxiliary cell or cell cluster comprising the cells or cell clusters that have at least one User Equipment subscribing for the Broadcast Multicast Service is no less than a preset threshold value. a Multi-cell/multicast Coordination Entity, MCE, determining a cell or cell cluster in which at least one User Equipment subscribing for a Broadcast Multicast Service is present; the MCE determining any cell or cell cluster which has no User Equipment subscribing for the Broadcast Multicast Service and is neighboring to the cell or cell cluster in which the at least one User Equipment subscribing for the Broadcast Multicast Service is present, as an auxiliary cell or cell cluster; and the MCE selecting any of the auxiliary cells or cell clusters that satisfies a preset condition, and determining both the selected auxiliary cells or cell clusters and the determined cell or cell cluster in which the User Equipment subscribing for the Broadcast Multicast Service is present as a Single Frequency Network area, characterized in that: the MCE selecting any of the auxiliary cells or cell clusters that satisfies a preset condition comprises: the MCE selecting any of the auxiliary cells or cell clusters so that neighboring cells or cell clusters of the selected auxiliary cell or cell cluster comprise cells or cell clusters that have at least one User Equipment subscribing for the Broadcast Multicast Service and the number of the neighboring cells or cell clusters of the selected auxiliary cell or cell cluster comprising the cells or cell clusters that have at least one User Equipment subscribing for the Broadcast Multicast Service is no less than a preset threshold value. the MCE selecting any of the auxiliary cells or cell clusters that satisfies a preset condition comprises: the MCE selecting any of the auxiliary cells or cell clusters so that neighboring cells or cell clusters of the selected auxiliary cell or cell cluster comprise cells or cell clusters that have at least one User Equipment subscribing for the Broadcast Multicast Service and the number of the neighboring cells or cell clusters of the selected auxiliary cell or cell cluster comprising the cells or cell clusters that have at least one User Equipment subscribing for the Broadcast Multicast Service is no less than a preset threshold value.
