Disclosed is a method used for session handling and a server. The method comprises the following steps: acquiring a session record of a group session; after confirming that the number of session objects in the group session is two according to the session record of the group session, conducting a session analysis on the session record and session duration of the two present session objects participating in the group session; and displaying a session switching interface in the group session after confirming the present group session is a single session based on the analytic result, wherein the session switching interface is used for inquiring the two present session objects participating in the group session whether the group session is switched to the single session. By utilizing the technical scheme, the rest users in a group to which the group session belongs cannot receive the session record of the two session objects forwarded by a server after the group session is switched to the single session, and thereby the receiving and sending mechanism of the group session can be optimized and the occupied bandwidth of such session records is reduced.
