Embodiment Construction

[0049] Since lawbreakers use call forwarding services to frequently transfer user conversations or calls to pay phone numbers, the basic idea of ​​the present invention is to increase judgment before the call forwarding operation is performed for the situation that lawbreakers will frequently use such services. The step of whether the number of times the business is initiated reaches the preset value, so as to avoid criminals from infringing on normal users to a certain extent.

[0050] like figure 1 As shown, it is a schematic flow chart of the first embodiment of the method for restricting explicit call forwarding in the present invention, refer to figure 2 A schematic diagram of signaling, this embodiment includes the following steps:

[0051] Step 201, the mobile switching center receives an explicit call transfer request sent by the first mobile terminal;

[0052] Step 202, the mobile switching center inquires about the number of explicit call forwarding initiations co...

Abstract

The related method for limiting ECT comprises: MSC or HLR queries the according to ECT request ECT number relative to the first mobile terminal, and decides whether the ECT number up to the pre-set maximal value, and rejects the ECT request if yes. It also refers to a method for limiting the forward transfer, which comprises: when meets the forward transfer condition, MSC or HLR queries the non-answer forward transfer number for the second terminal, and rejects the calling if the non-answer forward transfer number up to the pre-set value. This invention can limit the illegal behavior based onECT or non-answer forward transfer business.
