一种在通信网络中实现预付费业务的方法及系统 A method for implementing prepaid services in a communication network system and

技术领域 FIELD

本发明涉及通信网络的预付费业务实现方法,尤其涉及在码分多址(CDMA)1x网络和高速分组数据网络(EVDO)网络中与智能网相配合实现预付费业务的方法及系统。 The present invention relates to a communication network implemented method of prepaid service, and more particularly to intelligent network method and system for cooperating prepaid service in a Code Division Multiple Access (CDMA) 1x network and a high-speed packet data network (EVDO) network.

背景技术 Background technique

在当前通信系统提供的业务中,有一种预付费业务。 In the current service communications system provided, there is a prepaid service. 预付费业务是用户预先购买一定金额的服务的一种业务,例如在数据预付费业务中该服务体现为一定数量的使用时间或数据流量。 Prepaid service is a service user to pre-purchase a certain amount of services, such as prepaid services in the service reflected a certain amount of time or data traffic in the data. 在该预付费业务中,预付费网元设备实时跟踪用户对所购资源的使用情况,例如时间或流量的使用情况,并根据当前的使用情况实时从用户账户余额中扣除当前的使用费用。 In the prepaid business, prepaid network element equipment real-time tracking customer usage of purchased resources, such as usage time or traffic, and real-time usage charges deducted from the user's current account balance in accordance with current usage.

目前的预付费业务主要通过智能网来提供。 The current prepaid service is provided primarily by the intelligent network. 在智能网的业务控制点(SCP)中登记存储移动终端的号码和其对应的帐户,帐户中存储用户充值的金额,由SCP根据移动终端对所购资源的使用情况维护相应帐户中的金额。 The service control point of the intelligent network (SCP) in the registration storage number of the mobile terminal and a corresponding account, the account stored in user recharge amount, the maintenance amount corresponding account by the SCP according to the usage of a mobile terminal purchased resources.

对于无线通信接入网络尤其是码分多址(CDMA)网络,移动终端为移动台(MS),在SCP中采用MS的移动台号码簿号码(MDN)登记帐户。 In particular, code division multiple access (CDMA) network, a mobile terminal is a mobile station (MS), a mobile station MS using the directory number (the MDN) registered account in the SCP for a wireless communication access network. MDN为CDMA 1X网络中对MS的一个标识,是面向用户的终端号码,例如用户的手机号:13600008888。 MDN is a CDMA 1X network an identification of the MS, a number of user-oriented terminal, such as the user's phone number: 13600008888. 另外,在CDMA 1x网络中还使用用户网络接入标识(NAI)和国际移动用户标识(IMSI)对MS进行标识。 Further, in the CDMA 1x network user is also a Network Access Identifier (NAI) and the international mobile subscriber identity (IMSI) identifying the MS. 其中,NAI主要用于无线网络的接入,其形式例如:用户名@域名;IMSI中包括国家码、网络码、以及用户信息,主要用于计费。 Wherein, the NAI is mainly used for accessing a wireless network, for example in the form: user @ domain; the IMSI includes country code, network code, and the user information primarily used for billing.

图1为现有CDMA 1x网络中实现MS预付费业务的组网结构图。 FIG 1 is a conventional CDMA 1x network implemented MS prepaid service networking structure of FIG. 参见图1,该组网中主要包括无线网络(RN)、分组数据服务节点(PDSN)/预付费客户端(PPC)、授权、验证和计费(AAA)服务器、预付费服务器(PPS)、业务控制点(SCP)、以及综合业务管理平台(OSS)。 Referring to Figure 1, the networking includes a wireless network (the RN), a Packet Data Serving Node (PDSN) / prepaid client (the PPC), authorization, authentication and accounting (AAA) server, the prepaid server (PPS), service control point (SCP), and integrated business management platform (OSS). 其中:1、RN提供无线接入功能,分配空口资源、维护接口链路、转发报文、产生计费信息等。 Wherein: 1, RN providing wireless access, allocating air interface resources, link maintenance interface, to forward the packet, generating billing information. 该RN为无线接入网络设备,也即CDMA 1x网络设备。 RN is the radio access network device, i.e. CDMA 1x network device.

2、PDSN与PPC两个功能实体逻辑分开,物理合一。 2, PDSN and logical functional entities PPC two separate physical unity. PDSN/PPC作为预付费客户端,负责按MS的NAI或IMSI申请配额,监控配额使用情况。 PDSN / PPC as prepaid client, the MS according to the NAI or IMSI apply for quotas, quota usage monitoring. 所述的配额如所分配的可使用的时间或流量。 The quota as time traffic may be used or allocated.

3、AAA服务器中预先设置存储预付费MS的NAI或IMSI到MDN的映射关系,负责MS的认证和授权,并转发数据呼叫认证请求给PPS,获得该用户预付费业务的授权信息,判断用户的余额是否允许用户使用数据业务,并根据用户的使用情况实时扣费。 3, AAA server previously set stored prepaid the MS NAI or IMSI mapping to the MDN, is responsible for MS authentication and authorization, and forward the call authentication request to a PPS, authorization information of the user prepaid service, determine the user's balance whether to allow users to use data services, and real-time deductions based on usage of the user. 在预付费MS的漫游的情况下,拜访地AAA支持按漫游策略转发消息到归属地AAA。 In the case of the prepaid roaming MS, visited AAA support by roaming policy forward the message to the home AAA.

4、PPS用于向SCP申请可使用的金额,将金额转换成用户可使用的配额。 4, PPS for application to the SCP amount available, the amount converted into the quota available to the user. 维护用户已使用的费用,剩余费用等情况,决定下次给用户分配的金额。 User maintenance costs has been used, the remaining costs, etc., determine the amount assigned to the user's next.

上述AAA与PPS两个功能实体一般也是逻辑分开,物理合一。 The above-described PPS and AAA are generally two logical separate functional entities, a physical one.

上述PDSN、PPC、AAA服务器以及PPS属于核心网设备。 Above PDSN, PPC, AAA server and PPS belong to the core network equipment.

5、SCP用于给MS分配数据业务可使用的金额,并维护用户MDN相应帐户中的金额信息。 5, SCP amount allocated to the MS for a data service can be used, and the amount of information to maintain the user in the account MDN. 一般情况下,分组域与电路域共用SCP,预付费MS的数据和语音业务同帐户,根据MS的MDN统一管理。 In general, the common packet domain and CS domain the SCP, MS prepaid voice services and data with the account, the MDN unified management of MS.

6、OSS用于实现不同业务的统一帐户和统一的管理界面,目前各大运营商均有各自的OSS。 6, OSS to achieve a unified account management interface and unified different services that the major carriers have their own OSS.

在预付费MS用户登记预付费业务时,在归属AAA和SCP创建帐户,在归属AAA设置预付费MS的NAI或IMSI到MDN的映射关系;帐户信息和映射关系可以通过OSS下发并存储在预付费MS归属AAA和SCP中。 When the prepaid user of the MS registration prepaid service, create an account at the home AAA and the SCP, provided prepaid MS NAI of the home AAA or IMSI mapping to the MDN; account information and the mapping relation may be made and stored by the OSS prepaid fees MS home AAA and SCP. 当预付费MS进行通信时,通过RN发送MS的1x IMSI或NAI到PDSN/PPC;PDSN/PPC收到后发送接入请求报文到AAA进行认证和授权;AAA认证和授权成功后,根据NAI或IMSI查找预先存储的IMSI到MDN的映射关系,得到该预付费MS的MDN,PPS向SCP发送携带MDN的金额申请请求。 When the MS communicates prepaid, transmitted by the MS to RN 1x IMSI or NAI PDSN / PPC; PDSN / PPC received after sending an access request message to the AAA authentication and authorization; after AAA authentication and authorization is successful, according to the NAI IMSI IMSI or lookup previously stored mapping between the MDN, the prepaid MS to give the MDN, the amount of the PPS application request sent to the MDN carried SCP. SCP检验用户是否合法以及是否有余额,根据该MDN查询自身存储的预付费金额信息,给该预付费MS分配所请求的数据业务可使用的金额,从该MDN对应帐户的余额中扣除该部分金额,PPS根据用户业务费率将该金额转换为MS可以使用的配额,例如所允许使用的流量或时间,将分配的配额返回给AAA;AAA将配额返回给PDSN,PDSN允许该预付费MS进行通信,并监控配额的使用情况,例如监视MS通信时的数据流量或时间,并将这些使用情况信息发送给AAA,SCP根据用户的使用情况实时扣费。 Whether SCP test the user is legal and whether there is balance, according to the MDN query pre-stored by the payment amount information to the prepaid amount allocated to the MS of the requested data service that can be used, the part of the amount deducted from the balance of the MDN corresponds account , PPS rates the service based on the user is converted to a quota amount of MS can be used, such as traffic or use of the time allowed, the allocated quota returned to AAA; AAA quota returned to the PDSN, PDSN allow MS to communicate the prepaid , and to monitor usage of the quotas, such as data or traffic monitoring MS communication time, and the usage information to the AAA, SCP real-time deduction in accordance with the user's usage.

另外,CDMA 1x中的无线应用协议网关(WAPGW)中也统一通过MS的MDN来标识MS,WAPGW通过AAA提供的接口,在业务服务器中维护该MDN和用户信息,用于向MS用户提供WAP业务。 Further, CDMA 1x wireless application protocol gateway (WAPGW) unified also identified by MS MS MDN, the AAA through the interface provided by the WAPGW, the MDN maintenance user information and service server for providing a WAP service to the user of the MS .

上述为预付费MS用户直接拜访归属地AAA进行通信的实例。 Examples of the above-described communication for a prepaid user of the MS directly visited home AAA. 图2为预付费MS漫游时预付费网络结构示意图。 FIG 2 is a schematic diagram of a network structure when a pre-paid roaming prepaid MS. 参见图2,在预付费MS用户漫游的情况下,拜访地的AAA服务器支持按漫游策略转发接入请求报文到归属地AAA服务器进行处理。 Referring to Figure 2, in the case where the user of the MS prepaid roaming, the visited AAA server forwards the access request packet support to the home AAA server for processing by the roaming policy.

当前的CDMA 1x网络和智能网分别演进发展,CDMA 1x网络正在向高速分组数据网络(EVDO)演进发展,该EVDO网络也称为DO接入网,简称为DO网络,由于DO网络是纯分组域网络,新增了接入网认证、授权和计费(ANAAA)服务器,用于对MS用户进行接入认证授权,且移动终端中只有NAI,没有IMSI和MDN。 The current CDMA 1x network and intelligent network evolution and development, respectively, CDMA 1x network is evolving towards the development of high-speed packet data network (EVDO), which is also known as EVDO network DO access network, referred to as DO network, because the network is a pure packet domain DO network, the new network access authentication, authorization, and accounting (ANAAA) server, user access for MS authentication and authorization, the mobile terminal and only the NAI, IMSI and no MDN. 移动终端进行通信时,首先通过接入网络(AN)向ANAAA请求接入网的认证和授权,ANAAA根据移动终端的NAI返回一个IMSI给移动终端,移动终端再用该IMSI作为本次通信中本终端的标识进行后续业务流程。 When the mobile communication terminal, first requests authentication and authorization to access network ANAAA over access network (AN), ANAAA returns an IMSI to the mobile terminal, then the mobile terminal IMSI as the present mobile communication terminal according to the NAI of the present identification of the terminal for subsequent business processes. 移动终端每次呼叫移动终端所使用的IMSI可能不同,而且在分组(DO)数据业务过程中移动终端没有MDN。 IMSI of the mobile terminal used by the mobile terminal for each call may be different, but the packet (DO) data traffic during the mobile terminal no MDN.

然而,智能网在演进过程中依然普遍采用MDN对移动终端进行标识。 However, in an intelligent network evolution is still widely used for mobile terminals MDN identified. 因此现有CDMA 1x预付费方案无法适用于DO网络。 Therefore, the existing CDMA 1x prepaid plan can not be applied to the DO network. DO网络中还没有一种可以与智能网的SCP配合以进行预付费业务的方法。 DO network has not been a way for prepaid service can be used with SCP Intelligent Network.
