Method and device for determining single frequency network area

A device for determining a Single Frequency Network area, comprising:

• a Broadcast Multicast Service related cell or cell cluster determining unit, an auxiliary cell or cell cluster determining unit, and a Single Frequency Network area determining unit, wherein:
• the Broadcast Multicast Service related cell or cell cluster determining unit is adapted to determine a cell or cell cluster in which at least one User Equipment subscribing for the Broadcast Multicast Service is present;
• the auxiliary cell or cell cluster determining unit is adapted to determine a cell or cell cluster that has no User Equipment subscribing for the Broadcast Multicast Service and is neighboring to the cell or cell cluster having the User Equipment subscribing for the Broadcast Multicast Service;
• and
• the Single Frequency Network area determining unit is adapted to determine both the cells or cell clusters determined by the Broadcast Multicast Service related cell or cell cluster determining unit and any of the auxiliary cells or cell clusters determined by the auxiliary cell or cell cluster determining unit that satisfies predetermined conditions, as the Single Frequency Network area;
• wherein the Single Frequency Network area determining unit comprises a threshold value setting unit, an auxiliary cell or cell cluster conditionally selecting unit, and a configuration unit, wherein
• the threshold value setting unit is adapted to set a threshold value in advance, wherein the threshold value is equal to or more than 2;
• the auxiliary cell or cell cluster conditionally selecting unit is adapted to select 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 cells clusters that have at least one User Equipment subscribing for the Broadcast Multicast Service and have a number no less than the threshold value, and select 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;
• and
• the configuration unit is adapted to configure both the cells or cell clusters determined by the Broadcast Multicast Service related cell or cell cluster determining unit and the auxiliary cells or cell clusters selected by the auxiliary cell or cell cluster conditionally selecting unit as the Single Frequency Network area.
