Abstract

The invention provides a method for bypassing intelligent services of a called user, applied in the case that a GMSC and VMSC are not the same MSC. The method comprises: the GMSC sending information to the VMSC as to whether the intelligent services of the called user are bypassed in the GMSC; the VMSC determining whether the intelligent services are bypassed in the GMSC, and determining whether the intelligent services are bypassed in the VMSC; and when the VMSC determines that the intelligent services are bypassed in the GMSC and are not bypassed in the VMSC, the VMSC not triggering the intelligent services; when the VMSC determines that the intelligent services are not bypassed in the GMSC and are bypassed in the VMSC, the VMSC sending a call release message to the GMSC. The invention further provides a system and VMSC for bypassing intelligent services of a called user.

3. The method according to claim 1, wherein

In the step of the GMSC sending the information to the VMSC as to whether the intelligent services of the called user are bypassed in the GMSC, the GMSC sends a location request carrying the information to the VMSC by a home location register (HLR) as to whether the intelligent services of the called user are bypassed in the GMSC.

4. The method according to claim 3, wherein

the step of the GMSC sending the information to the VMSC as to whether the intelligent services of the called user are bypassed in the GMSC comprises:

the GMSC obtaining an intelligent trigger list of the called user from the HLR, analyzing whether the intelligent services of the called user are bypassed in the GMSC based on the intelligent trigger list of the called user, setting an intelligence bypass identifier based on whether the intelligent services of the called user are bypassed in the GMSC, and sending a location request carrying the intelligence bypass identifier to the VMSC by the HLR; and

in the step of the VMSC determining whether the intelligent services of the called user are bypassed in the GMSC based on the information as to whether the intelligent services of the called user are bypassed in the GMSC, the VMSC determines whether the intelligent services of the called user are bypassed in the GMSC based on the received intelligence bypass identifier.

5. The method according to claim 1, wherein

when the VMSC determines that the intelligent services of the called user are bypassed in the GMSC and that the intelligent services of the called user are not bypassed in the VMSC, the method further comprises:

the VMSC not sending an answer indication to a service control point (SCP) and sending a call request answer to the GMSC, and the GMSC forwarding the call request answer to a front office such that a calling user and a called user begin to talk.

14. The method according to claim 2, wherein

In the step of the GMSC sending the information to the VMSC as to whether the intelligent services of the called user are bypassed in the GMSC, the GMSC sends a location request carrying the information to the VMSC by a home location register (HLR) as to whether the intelligent services of the called user are bypassed in the GMSC.

6. A system for bypassing intelligent services of a called user, applied in the case that a gateway mobile switching centre (GMSC) and a visited mobile switching centre (VMSC) are not the same MSC, wherein

the GMSC is configured to send information to the VMSC as to whether the intelligent services of the called user are bypassed in the GMSC;

and

the VMSC is configured to determine whether the intelligent services of the called user are bypassed in the GMSC based on the information as to whether the intelligent services of the called user are bypassed in the GMSC, and determine whether the intelligent services of the called user are bypassed in the VMSC, and when the VMSC determines that the intelligent services of the called user are bypassed in the GMSC and that the intelligent services of the called user are not bypassed in the VMSC, not to trigger the intelligent services of the called user, and when the VMSC determines that the intelligent services of the called user are not bypassed in the GMSC and that the intelligent services of the called user are bypassed in the VMSC, send a call release message to the GMSC,

thereby supporting complete bypassing of the intelligent services of the called user.

7. The system according to claim 6, wherein the VMSC is further configured to:

bypass the intelligent services of the called user when the VMSC determines that the intelligent services of the called user are bypassed in the GMSC and that the intelligent services of the called user are bypassed in the VMSC, and
