Research On Upgrade Scheme Of Chongqing Telecom Voucher Center System

Chongqing telecom Voucher Center (Voucher Center, which is called VC), may use the unitive connection code to realize to each kind of pre-payment account number/card number charge cost, the inquiry is charged by the cost account number/card number and charge cost account number cryptogram is revised. The users unifies the charge cost service through the dial the connection code, the rechargeable card is released by the use of the charge cost platform. The rechargeable accountant may be the calling card number, the fixed telephone and Personal Hand-phone System and so on.At present the VC platform does not support the cross local network charge cost service. In the charge cost aspect; it only supports the solid speech, the young quick user's pre-payment and latter-payment user's charge cost; for data user as well as interconnection starry sky services it also does not support.Because the China telecom service give priority to the local service primarily, the entire net service and the mobile service by driving influence and the demand are not strong, therefore Chongqing existing VC charge cost system does not have the entire net and the entire service charge cost ability. Next step, in order to satisfy the China telecom group company request, Chongqing telecom has developed the charge cost platform, needs to carry on the transformation and the promotion of the local charge cost platform.This dissertation draws up from four aspects and analyses the Chongqing telecom VC charge platform to unify the charge transformation research:①VC charge correlation protocol is analysed, Carry threagh demand investigation, Verdict the demand criterion of Chongqing telecom VC system upgrade.Diameter CC: Credit controlling agreement is expanded, which based on Diameter Based.DCC Proxy: Diameter Credit Control Proxy. DCC protocol route Proxy, which is responsible for the Diameter protocol's transition.Between internal VC connection protocol charge system and various systems' internal access protocol.②In the second part, several kind of network schemes are introduced about VC unitive charge transformation (the entire intelligent network plan, half intelligent network plan, non-intelligent network plan), compared with its advantages and disadvantages, and unifies the Chongqing telecom actual situation choice realization book to save VC to unify the charge cost appropriate network construction.③In view of the Chongqing telecom VC charge cost network present situation, and unitive group company telecom network and the 3G network development direction, two key questions about research solution transformation process are discussed: VC province the communication protocol, the DCC agreement and the VC determined flow, we propose the Chongqing telecom VC charge cost network transformation implementation suggestion scheme in this research foundation. Integrated the entire intelligent network plan, half intelligent network plan, the non-intelligent network plan, based on present situation, Chongqing telecom chooses a set of reasonable scheme, which Chongqing telecom possibly choosed should be half intelligent network way.④Chongqing telecom VC unitive charge transformation scheme is researched:In order to guarantee VC unitive charge cleft grafting process not to affect the present net service running, we should realize unitive charge stable transition to entire net VC, VC unit charge transformation scheme is adopted in the following cleft grafting step: 1) Cleft grafting preparation; 2) Telephone service cleft grafting, 3) Service cleft grafting.Through this article research, we have designed the reasonable Chongqing telecom VC transformation plan. This scheme may instruct the charge cost platform as Chongqing telecom VC scheme and construction transformation reference instruction, which satisfies China Telecom corporate business and long-term development, China telecom development. Therefore ultimate objective of charge cost payment card: take the customer as the center, provide the unitive product range, the unitive connection code, entire service charge cost payment charge cost payment card product to the customer. Finally we provided the good customer experience and the convenience charge cost service to the clients.
