Abstract: To achieve the requirement of Single Frequency Network(SFN) area management that traditional operation algorithm of SFN area can not meet, E-MBMS logical architecture and deployment consideration are introduced and the characteristic of SFN area is studied by emulation. A novel and simple algorithm is proposed to meet the requirement, which is proved by emulation that the operation algorithm of SFN area of the traditional dynamic MBSFN is improved. How to select thresholds of algorithm is investigated. Its feasibility is demonstrated.
