<p>A handoff method of circuit switching (CS) call connection, the method comprises: when CS user need to handoff for accessing manner or accessed terminal during CS call procedure, controlling establish new call connection between CS network call controlling entity and the connection point that after handoff user handoff by CS network service controlling entity. Then controlling CS network call controlling entity connect communication between connection point after handoff and the other side user that communication with handoff user during initial CS call connection. Finally, the CS network call controlling entity and the connection point before handoff release call connection thereinto. Accordingly realizing ensure call continuity at the same time that handoff the original CS call to new call connection point during the communication. The connection point before handoff and after handoff is different terminal or same terminal that accessed to different communication networks, separately.</p> |
