Embodiment Construction

[0091] The invention connects the independent access device to the client end and the server end of the OCS (Online Charging System). The access device can control the application layer session and maintain the link between it and the server. The client (service control node) can control the service logic and maintain the link between it and the access device.

[0092] The user-defined message interface can be used for connection and communication between the above-mentioned client and the access device; the Diameter extension protocol interface can be used for connection and communication between the access device and the OCS server.

[0093] A physical connection is first established between the above-mentioned access device and the above-mentioned server, and after the capability exchange (Capabilities-Exchange, CE), the application layer link is established, and the above-mentioned client is notified to send CC (Credit Control ) message to avoid call loss caused by the li...

Abstract

The invention discloses a device, a system and a method for reducing call loss in on-line billing, which belong to the field of communication. The device can be connected and communicated with an on-line billing client and a server respectively, and can comprise an internal communication module connected and communicated with the client to carry out information interaction, a call loss reducing module which receives information sent by the internal communication module, identifies a session message of the information to generate a session identifier and carries out session management, and an external communication module connected and communicated with the call loss reducing module and the server respectively to carry out information interaction. The system and the method can separately manage service logic control and session maintenance by arranging access equipment, and utilizes various mechanisms, such as redundance, dynamic load feedback, resending overtime, abnormal link and notification on busy, to protect service message security to reduce the call loss.

Description

technical field [0001] The present invention relates to the communication field, in particular to a device, system and method for reducing call loss by online charging. Background technique [0002] An online charging system (Online Charging System, OCS) can be used to implement online charging, providing functions such as prepayment and real-time account processing. The existing online billing system can separate the customer's traffic control function from the billing function, establish a direct interaction between the billing mechanism and session / service control, and enable billing to participate in the use of services. In this way, the powerful ability of independent billing can be used to provide the flexibility close to the quasi-real-time billing system, and the real-time characteristics of participating in the use process can be used to minimize the cost of arrears. [0003] Currently, the online charging protocol (OCP) used to access the online charging system i...
