Abstract

The embodiment of the invention discloses a call charging method, service control equipment and a call control system, which are used for avoiding that the expense of the previous conversation cannot be deducted because the reserved amount of the previous conversation is occupied by the next conversation when the balance of account of the user is lower. The method disclosed by the embodiment of the invention comprises the steps: the service control equipment receives a call control request sent by switching equipment, extracts call characteristic parameters included in the call control request, and judges whether call control items corresponding to the call characteristic parameters exist; if yes, the service control equipment returns a rejection call message to the switching equipment; and if not, the service control equipment sends a charging request to the charging equipment. The invention also provides the service control equipment and a call control system.

Description

technical field [0001] The invention relates to the communication field, in particular to a call charging method, service control equipment and a 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 switching point (SSP, service switch point) reports the originating application (ORREQ, Origination Request) message interacts with the Service Control Point (SCP, Service Control Point), and the SCP sends a Credit Control Request (CCR, Credit Control Request) message to the Convergent Billing Point (CBP, Convergent Billing Point) to perform price approval and in user A's The amount is reserved in the account, and then CBP feeds back a credit control answer message (CCA, Credit Control Answer) to the SCP, and the SCP sends an initial application authorization message to the SSP, and user B starts...
