Abstract

The present invention discloses a call pick-up method, a pick-up server and a communication system. After receiving a request, which is sent by a pick-up party, for substituting a caller to respond a call, a pick-up server redirects the call to the pick-up server which controls the talk between a caller and the pick-up party. As the caller is always a call initiating party during the whole call flow, by the caller reinitiating a call or directly routing the call to the pick-up server and the pick-up server controlling the talk between the caller and the pick-up party, the flow is the same as the ordinary flow of the call initiation of the caller in the view from the flow of the caller; a universal means can be adopted to count the fee of the caller, the fact that a universal billing process is required to be modified to support the pick-up service in the pick-up method of the prior art is avoided, so that the implementation of the call pick-up service is simpler, rational and convenient in popularization and application.
