Problems solved by technology

[0012] (1) In the first processing method, the DCH parameters in the O_CSI signed by the user are not judged, and the DCH parameters in the MSC / SSP are directly processed in a unified manner, and the control is not performed according to the user's subscription information and user credit level
[0013] (2) In the second processing method, since the value of the DCH parameter has only two signs of continuing the call and canceling the call, although the user can continue to connect the call through the DCH parameter, it cannot be controlled according to the user's credit level
If users take advantage of the loopholes that SCP cannot be billed in real time but can connect calls to make a large number of calls, such as international long-distance calls, entertainment calls, etc., it will bring direct economic losses to the operator

Embodiment 1

[0037] At present, the agreement stipulates that the value of the DCH parameter in the O_CSI is 0 to indicate that the call is continued, and the value of 1 is to indicate that the call is removed. It is also suggested in the protocol that the value of the DCH parameter is 2 to 31, which can be regarded as continuing the call; the value of the DCH parameter greater than 31 is considered to be disconnected.

[0038]In this embodiment, the DCH parameter in the O_CSI in the protocol is used to expand the value range of the DCH parameter and set the call type that is allowed to be dialed corresponding to the DCH parameter value. For example, you can use the value 2 of the DCH parameter to indicate that only local calls are allowed, the value 3 of the DCH parameter indicates that local calls and domestic long distance calls can be made, and the value 4 of the DCH parameter indicates that local calls, domestic long distance calls and entertainment calls can be made. , a value of 5 f...

Embodiment 2

[0050] At present, the agreement stipulates the corresponding relationship between the DCH parameter in O_CSI and the call control, that is, the value of the DCH parameter is 0, which means that the call is continued; the value of the DCH parameter, which is 1, means that the call is removed. In addition to the DCH parameter, the O_CSI specified in the protocol also has a reserved extension bit (extensionContainer). In this embodiment, in the case that the DCH parameter value corresponds to continuing the call, the call class for allowing the call is further set. For example, an extension parameter value of 2 indicates that local calls are allowed; an extension parameter value of 3 indicates that local calls and domestic long-distance calls can be made; an extension parameter value of 4 indicates that local calls, domestic long-distance calls and entertainment calls are allowed; the extension parameter value A value of 5 means that you can make local calls, domestic long-dista...

Embodiment 3

[0066] In the second embodiment, the parameter value of the extension bit is represented by an integer, and each integer represents the range that the user can call. In order to assign call levels to users more flexibly, in this embodiment, the parameter value of the extension bit is represented by a binary number, and each bit of the binary number represents a call type that is allowed to be dialed. For example, when an 8-bit binary number is used to represent the extended digit, the first digit of the binary digit of the extended digit represents a local call, the second digit represents a domestic long-distance call, the third digit represents an entertainment call, and the fourth digit represents an international long-distance call. In practical application, which type of call each binary bit represents can be set arbitrarily. At this time, if the extension digit is a binary number of 10100000, the user can make local calls and entertainment calls; if the extension digit i...

Abstract

The present invention discloses call control method. Said method includes visiting mobile switching center MSC, according to said originating calling party O-CSI parameter values finding said corresponding relation, to obtain with said parameter values corresponded permission calling type, and judging user originating calling type whether belonging to permission calling type, is then continue switching this calling; otherwise canceling this calling. According to said invention disclosed method, user can set permission calling type corresponded parameter to make flexibly calling control.

Description

technical field [0001] The invention relates to communication technology, in particular to a call control method. Background technique [0002] Smart service logic is now widely used in mobile networks, such as prepaid (PPS) service calls. In the GSM0902-710, 0978-700, and 0378-710 agreements, when a user who subscribes to a customized application (CAMEL) information of mobile network enhanced logic initiates a call, the user's visiting mobile switching center (MSC) / service switching point ( The SSP) triggers a service process according to the originating-CAMEL Subscription Information (O_CSI) of the user. figure 1 Shown is the PPS service call flow in the existing mobile network, including the following steps: [0003] Step 101: The CAMEL user initiates a call. [0004] Step 102: The visiting MSC / SSP of the calling user reports an initial call judgment point (IDP) message to the Service Control Point (SCP) according to the calling user's subscription information O_CSI, t...
