Method, device and system to realize virtual private network charging

Abstract

The embodiment of the invention discloses a method which realizes the accounting of virtual private networks and comprises the following steps that an accounting network element receives and calls the accounting requests sent by an access control network element; wherein, the accounting requests comprise the VPN information and accounting information of call subscribers and / or called subscribers; the accounting network element judges whether the user account balance is adequate, or whether the user account balance is insufficient but the credits of users meet the requirements, if yes, the access control network element is informed to go on with the call flow and deducts corresponding expenses from the user account balance or records the expenses real-timely according to the received VPN information and the accounting information, otherwise, the access control network element is informed to stop the call flow. The embodiment of the invention also discloses a device and a system which realize the accounting of virtual private networks. With the adoption of the embodiment of the invention, the mutual fusion of prepayment and postpaid accounting can be well realized, which ensures different users to get the same experience.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for realizing virtual private network charging. Background technique [0002] In the prior art, a virtual private network (VPN) is a logical private network established on the public land mobile communication network (PLMN) and the public fixed telephone network (PSTN). Using this private network, through abbreviated dialing, The special numbering plan and other methods enable enterprises and group users to communicate with each other in the group. The open VPN service within the PLMN can provide private network services similar to PSTN small and medium-sized exchanges (PBX) for mobile users within the group who have applied for this service. [0003] In the prior art, the VPN service can be implemented in two ways, namely the intelligent network mode and the BOSS mode. The billing implementation method in this way will be described in detail:...

AI Technical Summary

Problems solved by technology

[0010] However, the VPN service implemented in the form of an intelligent network fails to effectively integrate the prepaid service and the postpaid service, resulting in the following disadvantages:

[0011] 1) Real-time billing and deduction can be performed for prepaid users, but this function cannot be realized for postpaid users, resulting in inconsistent experience between prepaid users and postpaid users on the intelligent network

[0012] 2) In this prior art, the account data of prepaid users are stored on the intelligent network, while the account data of postpaid users are stored on the BOSS system. Since the data models of the intelligent network system and the BOSS system are different, prepaid and postpaid users have different data models. The conversion of payment requires a very difficult data migration between the intelligent network system and the BOSS system, which makes it impossible to realize the flexible switching of pre-paid and post-paid methods

[0018] It can be seen from the above that the VPN service implemented by the BOSS method can only support postpaid users. Therefore, the mutual integration of prepaid and postpaid cannot be realized, so that it is impossible to perform real-time billing and deduction for users using the VPN service. It is impossible to perform inquiries to obtain information such as call charges and account balances, so that users cannot obtain the real-time experience that prepaid services can provide

[0019] In addition, in this method, since the control point of the call is the switching device, the switching network cannot provide the short number translation function without changing the business logic, so the short number dialing and short number caller ID functions are not supported

[0020] To sum up, in the specific ways of implementing VPN services provided by the prior art, the mutual integration of prepaid services and postpaid services cannot be realized, resulting in different experiences of prepaid users and postpaid users; Unable to achieve flexible switching between prepaid and postpaid
