Patent ID: 8897194

Claim:
A method for determining a Single Frequency Network area, comprising: determining a cell or cell cluster in which at least one User Equipment subscribing for a Broadcast Multicast Service is present; 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 User Equipment subscribing for the Broadcast Multicast Service is present, as an auxiliary cell or cell cluster; and 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; wherein selecting any of the auxiliary cells or cell clusters that satisfies a preset condition comprises: 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 cluster that have the User Equipment subscribing for the Broadcast Multicast Service and have a number no less than a present threshold value, and wherein the preset threshold value is equal to or more than 2, the method further comprises: selecting any of the auxiliary cells or cell clusters if the strength of a pilot signal in the auxiliary cell or cell cluster is larger than a further threshold value.
