摘要： The invention discloses a method and a network structure for moving a call leg, implementing call leg move with this network structure. The method includes: A. creating a call-leg-moving interface and its method interface reference parameters, which are used to move a call leg from an original call to a destination call, wherein the said interface reference parameters are: a identifier of a call leg to be moved and a destination call identifier; B. if application wants to move the said call leg to be moved, determining the interface reference parameters according to said call leg and destination call, invoking said call-leg-moving interface to move said call leg from said original call to said destination call with said interface reference parameters .The invention provides a simple, convenient, easy to implement and spread interface to application in order to move a call leg from one call to another.
