The invention discloses a communication method and a server in POOL networking, and relates to the technical field of communication. After the technical scheme is adopted, the number of times of station-to-station calls between a first terminal collection and a second terminal collection is reduced by carrying out forward migration on a first migration terminal, resources occupied by the station-to-station calls are reduced, and the performance of a system is enhanced. The method can specifically comprises the steps that the server randomly selects a first MSC and a second MSC form at least two MSCs, first call bill information is obtained from the first terminal collection, and the forward migration is carried out on at least one first migration terminal in the first terminal collection according to the first call bill information and based on a principle of minimum number of times of the station-to-station calls or a principle of maximum number of times of the station-to-station calls. The communication method and the server in the POOL networking can be applied to the communication in the POOL networking.
