Abstract  Abstract

This invention is a kind of method and system to keep the continuity of a conversation. The system includes: a network a HOSF entity a HODF entity a HOAF-CP entity and a HOAF-UP entity. The method includes: the 1st user sets up a connection with the HOAF-CP entity and the HOAF-UP entity which are corresponding to the 2nd user with the HOSF entity. When conversation switching is being proceeded the HODF entity which is corresponding to the HOSF entity will set up a connection with the HOAF-CP entity and the HOAF-UP entity and the 1st use is able to continue the aforementioned conversation with the aforementioned connection. This invention is able to replace the connection before or after the switching logically on using to guarantee the intercommunicative continuity between the users even if the switch-in device of the terminal the switch-in mode of the terminal or the terminal itself is changed.

The present invention discloses a method and system of holding session continuity the system includes: network hand off source point faction(HOSF) entity hand off destination point faction (HODF) entity hand off anchor point faction control panel (HOAF-CP) entity and hand off anchor point faction user panel (HOAF-UP) entity. The method comprises: the first user connect with the HOAF-CP entity and the HOAF-UP entity that correspond to the second user by HOSF entity and the first user holds a session with the second user. When performing session switching the HODF entity that corresponds to the HOSF entity be connected with the HOAF-CP entity and the HOAF-UP entity. The first user continues the session by the connection. The present invention can replace the connection of before switching and after switching on application logic so that ensure continuity of interactive session between users when access address of terminal or access mode of terminal or terminal itself be changed.
