Embodiment 1
[0066] Figure 4 It is a preferred flow chart of a method for processing late forwarding by a user according to an embodiment of the present invention, including the following steps:
[0067] S402, the calling user calls the called user;
[0068] S404, the home location register of the called user sends the routing confirmation message carrying the late forwarding information to the gateway mobile switching center;
[0069] S406, when the visited mobile switching center of the called user finds that the called user cannot answer, the gateway mobile switching center connects the call to the user indicated by the late forwarding information.
[0070] In this preferred embodiment, the direct connection between the calling user and the forwarding-to user is adopted without going through the detour of the called user to visit the mobile switching center, which solves the problem that the detour of the conversation cannot be avoided and the waste of conversation resources is caused...
Embodiment 2
[0077] Figure 5 It is a preferred structural block diagram of a system for processing late forwarding of users according to an embodiment of the present invention, including: a called user's home location register 502, a gateway mobile switching center 504, and a called user's visiting mobile switching center 506, wherein, in the main When the calling user calls the called user, the home location register 502 is used to send the routing confirmation message carrying the late forwarding information to the gateway mobile switching center 504; the visiting mobile switching center 506 is used to page the called user; the gateway mobile switching center 504 is used to connect the call to the user indicated by the late forwarding information when the called user's visiting mobile switching center 506 finds that the called user cannot answer.
[0078] In this preferred embodiment, the direct connection between the calling user and the forwarding-to user is adopted without going thro...
