Problems solved by technology

[0003] However, in the above-mentioned prior art, before the SCP side actively inquires about the SSP, user A may initiate a call again. If the amount has not been released and the balance of user A's account is insufficient, the re-initiated call will not be established, which will affect the end user experience

Embodiment Construction

[0014] The embodiment of the present invention provides a call billing and device, which is used to avoid the possibility of call failure because the amount is not released in time, reduce the connection rate, and affect the end user experience, which will be described in detail below.

[0015] In the application document with the application number 200910162023.1, in order to solve the above-mentioned shortcomings, a method of reservation management based on the calling party's user information, call information and service (including call, SMS or other services) characteristics is adopted. When user A initiates a call At the time, the CBP side detects whether there is call reservation information including user A and user B. If it exists, the amount reserved in the previous call is released in time before the call starts to reserve the amount, which can prevent user B from picking up The former user A actively abandons the problem that the reserved call amount cannot be released...

Abstract

Disclosed are a call charging method, a service control device, and a call control system, for use in preventing the incapability to debit the charges of a preceding call due to a reserved credit of the preceding call being occupied by a subsequent call when the balance in the account of the user is relatively low. The method of embodiments of the present invention comprises: the service control device receiving a call control request transmitted by a switching device; extracting a call-specific parameter comprised within the call control request; determining whether or not a call control entry matching the call-specific parameter is present; if yes, returning a call rejection message to the switching device; if not, transmitting a charging request to a charging device. Also provided in the present invention are the service control device and the call control system.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a call charging method, service control equipment and call control system. Background technique [0002] The call signaling interaction process in the Code Division Multiple Access (CDMA, Code Division Multiple Access) network is as follows. When user A initiates a call to user B, the service switch point (SSP) reports an origination request (ORREQ, Origination). The Request) message interacts with the Service Control Point (SCP). The SCP sends a Credit Control Request (CCR) message to the Convergent Billing Point (CBP) to rate the price and check the user A’s The amount is reserved in the account, and then CBP feeds back a Credit Control Answer (CCA, Credit Control Answer) message to the SCP. The SCP sends an initial authorization request message to the SSP. User B starts to ring. If user B goes off-hook, the user If A hangs up and abandons the call, the SSP does not immediately...
