Problems solved by technology

If in this method, the forwarding number of the one-device double-number terminal is a domestic number, the foreign MSC cannot use the domestic forwarding subscription information. The forwarding number is the same as the Chinese HLR, and a synchronization mechanism needs to be provided to ensure that the core network data on both sides is consistent, but this method has certain difficulties in actual implementation

Embodiment 1

[0075]Embodiment 1 is applicable to the case where the core network where the one-device-multi-number terminal currently resides is the same core network as the core network to which the calling party who calls the one-device multi-number terminal belongs. In this case, after the calling party calls the one-machine-multiple-number terminal, the service control point determines the number of the one-machine multiple-number terminal that belongs to the core network where the terminal is currently located as the called number, and the called number When the forwarding service type of the calling party is the forwarding on no answer type and the one-machine-multiple-number terminal does not answer within a predetermined time, the mobile switching center in the core network to which the calling party belongs learns from the service control point that the called The forwarding number of the calling number.

specific Embodiment 1

[0078] Such as Figure 5 As shown, when the core network where the one-machine-multiple-number terminal is currently located is the same core network as the core network to which the calling party who calls the one-machine multiple-number terminal belongs, the method for realizing the call forwarding of the one-machine multiple-number terminal includes the following steps, The transfer operation of the signal by STP is ignored.

[0079] In step 501, the calling party calls a one-machine-multiple-number terminal, and the MSC to which the calling party belongs sends a message (LOCREQ message) to the called HLR to request to obtain the called smart service subscription information.

[0080] Step 502, the called HLR notifies the MSC of the smart service subscription information of the called number (through the LOCREQ message).

[0081] Step 503, the MSC learns that the called terminal is a one-device-multiple-number terminal, sends a message to the SCP to trigger the one-device ...

Embodiment 2

[0093] Embodiment 2 is applicable to the case where the core network where the one-machine-multi-number terminal currently resides is not the same core network as the core network to which the calling party who calls the one-machine-multi-number terminal belongs. In this case, after the calling party calls the one-machine-multiple-number terminal, the service control point determines the number of the one-machine multiple-number terminal that belongs to the core network where the terminal is currently located as the called number, and the called number When the forwarding service type of the calling party is the forwarding on no answer type and the one-machine-multiple-number terminal does not answer within a predetermined time, the mobile switching center in the core network to which the calling party belongs learns from the service control point that the called The forwarding number of the calling number.

Abstract

A method, system and service control point for implementing call forwarding of a one-phone-multiple-number terminal are provided by the present invention, which can improve call forwarding processing ability of the system for the one-phone-multiple-number terminal in a network structure with one intelligent network being simultaneously connected with multiple core networks. The method includes: forwarding service information of the one-phone-multiple-number terminal is stored in the service control point which is simultaneously connected with multiple core networks; when a mobile switching center in a core network, to which a calling party belongs, receives a request from the calling party for calling the one-phone-multiple-number terminal, the mobile switching center perceives the called number from the service control point; when the called procedure of the called number conforms to the forwarding condition, the mobile switching center in the core network, to which the calling party belongs, perceives the forwarding number of the called number from the service control point, and calls the forwarding number.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method, a system and a service control point for realizing forwarding calls of terminals with one machine and multiple numbers. Background technique [0002] With the continuous expansion of telecommunication services in domestic and overseas markets, the integration of old and new networks has become an important issue. In order to take into account existing network resources and user interests, some operators have launched a multi-number service for one device. Users only need to use one terminal to enjoy corresponding telecommunications services under specific conditions or locations, such as domestic one-device-two-number (CDMA number + PHS number) service, MVNO (Multiple Virtual Number) service in the North American market, etc. figure 1 The network structures shown are supported. Such as figure 1 As shown, the intelligent network can be connected to two or more core...
