Description

一种基于区块链漫游交易的方法、装置
相关申请的交叉引用
本申请要求在2019年11月11日提交中国专利局、申请号为201911097222.9、申请名称为“一种基于区块链漫游交易的方法、装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种基于区块链漫游交易的方法、装置。
背景技术
在通信过程中，经常涉及漫游业务，即终端设备从常驻的服务区域(即签约服务区域)通过漫游移动到其他服务内的通信网络。其中，终端设备签约服务区域以外的其他服务区域可以称为漫游服务区域。运营商在签约服务区域内提供的通信网络可以简称为签约地网络，运营商在漫游服务区域内提供的通信网络可以简称为漫游地网络。
与此同时，终端设备在进行漫游业务时，漫游地网络的运营商漫游运营设备还会根据终端设备在漫游地网络进行通信时所产生的话单文件，向所述终端设备对应的签约地网络的运营商收取漫游费用，其中，所述签约地网络的运营商可以简称为归属运营设备，漫游地网络的运营商可以简称为漫游运营设备。
目前，现有技术中，运营商之间的漫游及结算漫游费用的过程包含漫游前、中、后三个阶段。漫游前，运营商之前建立漫游关系，交换漫游协议，公布各种漫游相关的公共参数。在这个过程中，归属运营设备会获得漫游运营设备针对漫游业务的收费协议，并以此制定签约终端设备在漫游过程中的用户漫游资费。漫游过程中，终端设备在接入漫游地网络后产生漫游，漫游运营设备将终端设备的话单文件通过漫游财务结算系统发送给归属运营设备。漫游后，归属运营设备根据话单文件向漫游运营设备结算漫游费用，并且，归属运营设备根据获得的话单文件向终端设备结算漫游零售费用。其中，在无论何种漫游模式，运营商之间的账单结算都需要通过可信的漫游清算中心进行仲裁公证。
上述通信过程中漫游业务的主要问题是：现有传统的漫游话单结算系统中，话单出账时延以天为单位，其滞后性为话费欺诈提供了潜在机会，且人工操作导致的可靠性和安全性上的缺失也难以避免。同时，现有漫游业务中，运营商之间的账单结算都需要通过可信的漫游清算中心进行仲裁公证，而对于仲裁的依赖带来的漫游成本提升也是亟需解决的问题。

具体实施方式
下面将结合附图对申请实施例的具体实施过程进行详尽的描述。
在通信过程中，经常涉及漫游业务，即漫游地网络中的漫游运营设备向签约地网络中的归属运营设备提供终端设备的漫游话单，并从中结算收取漫游费用。其中，漫游运营设备与所述归运营设备之间的漫游及清结算过程包含漫游前、中、后三个阶段。漫游前，漫游运营设备与归属运营设备之间建立漫游关系，交换漫游协议，公布各种漫游相关的公共参数。在这个过程中，归属运营设备会获得漫游运营设备发送的基于所述漫游协议确定的漫游费用，并根据所述漫游费用以及自身运营成本制定签约UE在漫游过程中的漫游零售费用。漫游过程中，UE在漫游地网络中接入服务产生漫游，所述漫游运营设备将所述UE的漫游话单通过漫游财务结算系统发送给归属运营设备。漫游后，归属运营设备根据漫游话单数据记录文件向漫游运营设备结算漫游费用，并且，归属运营设备根据获得的漫游话单向对应UE结算漫游零售费用。其中，在无论何种漫游模式，运营商之间的账单结算都 需要通过可信的漫游清算中心进行仲裁公证。
上述传统的漫游话单结算系统中，存在的主要问题是话单出账时延以天为单位，其滞后性为话费欺诈提供了潜在机会，且人工操作导致的可靠性和安全性上的缺失也难以避免。同时，运营商之间的账单结算都需要通过可信的漫游清算中心进行仲裁公证，而对于仲裁的依赖带来的漫游成本提升也是亟需解决的问题。
进一步的，随着区块链技术的不断发展，基于区块链分布式账本技术所具有的不可篡改性等特点，在通信过程中，也逐渐致力于打造基于所述区块链的安全漫游话单结算平台，用以解决传统电信网络系统中，松散的漫游结算体系的高成本、高延迟以及财务欺诈等问题。
然而，在传统的区块链中，区块链本身带来的隐私问题是传统架构中不存在的。例如以比特币为代表的区块链的支付平台，需要在交易中明确标明交易双方的账户和交易金额，使得漫游话单信息对所有实体均可见，漫游交易双方的隐私无法得到保障，这对于漫游交易的双方显然是不可接受的。
为解决该问题，本申请实施例提供一种基于区块链支持漫游业务的方法。本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统，全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统，未来的第五代(5th Generation，5G)系统，如新一代无线接入技术(new radio access technology，NR)，及未来的通信系统，如6G系统等。
以5G系统(也可以称为New Radio系统)为例，具体来说，为了在保障交易双方隐私的前提下，基于区块链技术进行漫游业务的方法主要采用零知识证明技术。通过该方法，可将漫游运营设备与归属运营设备之间的转账信息隐藏起来，使得漫游交易的支付行为不可追踪。
为便于理解本申请实施例，首先以图1中示出的通信系统为例详细说明本申请实施例适用的通信系统。如图1所示，该通信系统包括漫游运营设备100、终端设备101、归属运营设备102和区块链103。
漫游运营设备100，位于所述漫游地网络中，在通信系统中用于为接入的终端设备101在所述漫游地网络中提供无线通信功能的设备，可以确定所述终端设备101对应的归属运营设备102进行漫游服务产生的漫游服务费，以及通知并收取所述归属运营设备102所述漫游服务费。漫游运营设备100也可称为基站(base station，BS)。目前，一些漫游运营设备100的举例为：5G中的下一代基站(g nodeB，gNB)、演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(baseBand unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心等。
进一步的，如图2所示，所述漫游运营设备100中包括的网元主要包括：会话管理功能(Session Management Function，SMF)、接入和移动管理功能(Access and Mobility Management Function，AMF)、接入和移动管理功能(Charging Function，CHF)、账单域(Billing Domain，BD)、区块链处理功能(BlockChain Handling Function，BCHF)、安全 边缘保护代理(Security Edge Protection Proxy，SEPP)、策略控制功能(Policy Control Function，PCF)、用户端口功能(User Port Function，UPF)以及无线接入网(Radio Access Network，RAN)等。
其中，所述SMF在漫游通信业务中主要用于向CHF发送话单；所述CHF用于根据所述SMF提供的多份账单以及所述漫游运营设备与所述归属网络设备102之间协商的漫游协议，整理出当前时段的话单记录文件并发送至BD；所述BD为所述漫游运营设备的整个结算中心，可以直接查询所述区块链103，也可以通过区块链处理功能BCHF进行传递，主要用于确定所述话单文件对应的漫游费用，并通过初始铸币过程产生与所述漫游费用额度相同的货币声明；所述BCHF用于建立所述漫游运营设备100与所述区块链103之间的连接，从而使所述漫游运营设备可将交易记录、货币声明等信息存储到所述区块链以及从所述区块链中获取相关信息，对区块链中对应的信息进行处理操作等。
所述漫游运营设备也可称为第一网络设备，换言之，第一网络设备可以是漫游地网络中的一个或多个网元，也可以是漫游地网络中一个或多个功能模块，本申请实施例对第一网络设备的具体形态和结构不作限定。
需要说明的是，本申请实施例中所述BD还可以为计算设备，对区块链的查询和访问通过BCHF传递。
终端设备101，是一种向用户提供语音和/或数据连通性的设备，也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。
归属运营设备102，位于所述签约地网络中，在通信系统中用于为接入的终端设备101在所述签约地网络中提供无线通信功能的设备，可以核算所述漫游运营设备100发送的所述终端设备101进行漫游服务产生的漫游服务费，并在确定所述漫游服务费没有问题后向所述漫游运营设备100支付所述漫游费用；以及制定并收取所述终端设备101所述漫游服务费。归属运营设备101也可称为基站(base station，BS)。目前，一些归属运营设备101的举例为：5G中的下一代基站(g nodeB，gNB)、演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(baseBand unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心等。
进一步的，如图2所示，所述归属运营设备102中包括的网元主要包括：SMF、CHF、BD、BCHF、SEPP、PCF、UPF、UDM(Unified Data Management，统一数据管理)以及DN(Downstream Node，下行节点)等等。其中，所述SMF在漫游通信业务中主要用于向CHF发送话单；所述CHF用于根据所述SMF提供的多份账单以及所述漫游运营设备与所述漫游运营设备100之间协商的漫游协议，整理出当前时段的话单记录文件并发送至BD； 所述BD为所述归属运营设备102的整个结算中心，可以直接查询所述区块链103，也可以通过区块链处理功能BCHF进行传递，主要用于通过查询所述区块链103进行话单验证；所述BCHF用于建立所述归属运营设备102与所述区块链103之间的连接，从而使所述归属运营设备可从所述区块链中获取相关信息，进行话单验证，以及对区块链中对应的信息进行其他处理操作等。
所述归属运营设备也可称为第二网络设备，换言之，第二网络设备可以是签约地网络中的一个或多个网元，也可以是签约地网络中一个或多个功能模块，本申请实施例对第二网络设备的具体形态和结构不作限定。
需要说明的是，本申请实施例中所述BD还可以为计算设备，对区块链的查询和访问通过BCHF传递。区块链103，是一种分布式账本的安全实现，以区块作为数据结构存储交易信息，每个区块包含区块体和区块头。其中，区块体存储交易记录。交易记录根据本申请实施例一种实现方式中应用场景需要，可以为转账记录、智能合约记录、清算记录、数据记录等；区块头存储时间戳、交易的哈希汇总结果，以及使之和前序区块形成链式结构的必要信息。
其中，本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。应理解，图1和图2仅为便于理解而示例的简化示意图，该通信系统中还可以包括其他网络设备或者还可以包括其他终端，图1和图2中未予以画出。
以下再对本申请实施例中涉及的部分用语进行解释说明，以便于理解。
1)零币(Zcoin)，是一种技术，在Zcoin中，货币持有的方式是将代表固定面额的随机数记录在区块链中，即本申请实施例中的货币声明，而持有者自身秘密保存该随机数背后的序列号和逻辑关系。支付时，持有者出示序列号，并通过零知识证明来声明该序列号和记录在区块链中的某个货币声明存在逻辑关系。但是零知识证明本身又在这个过程中不暴露所述货币声明。也就是Zcoin可以通过固定面额的货币本身为单位，用户以公开的方式或者匿名的方式在区块链中拥有某货币，而以隐藏的方式使用该货币支付某次费用。这个特点，使得交易过程中的转账账户隐私也能够得以有效保护。
其中，一个固定面值的货币在Zcoin中包含两个参数，公布在区块链上的货币声明和货币持有者的隐私序列号，且所述货币声明可以通过所述货币持有者的隐私序列号以及另一个参数进行确定。例如，假设所述货币声明为货币声明C，所述货币持有者的隐私序列号为S，则存在某随机隐藏值r，使得(S,r)的某公开运算能推导出C。
本申请实施例中，为方便描述，将所述货币声明以及所述货币声明对应的两个参数S，r共同称之为声明信息；将所述两个参数S，r，表示为货币验证信息。即本申请实施例中所述声明信息表示(C，S，r)，货币声明表示C，所述货币验证信息表示(S,r)。
本申请实施例中，所述货币声明C对应的隐私序列号S和随机隐藏值r可安全存储于持有者对应的BD中，且为了安全性考虑，不以任何形式提供针对S和r的对外的读取访问接口。
可选的，本申请实施例中允许计费功能体CHF，区块链处理功能体BCHF等其他网元安全管理这些匿名货币。
2)铸币，在本申请实施例中主要包括两个方面：所述漫游运营设备根据某轮漫游服务业务产生的漫游费用通过初始铸币过程产生相应额度的货币声明。其中，该货币声明可以为多种不同面额的货币声明的组合。例如，第一货币声明可以为货币声明1、货币声明2、货币声明3的组合。
所述漫游运营设备将所述货币声明存储在所述区块链中，将所述货币验证信息安全存储在所述漫游运营设备的BD中，直到在未来的支付过程中有归属运营设备完成对所述货币声明的支付，则确定完成铸币。也就是说，所述铸币过程主要是生成无效货币，然后使所述无效货币在被完成支付后成为有效货币的过程。
可选的，本申请实施例中为确保生成的声明信息中的S的唯一性，所述漫游运营设备在确保S不被暴露的情况下，可以查询区块链中是否已有相应序列号，若存在，则生成新的S，然后可继续进行所述S的唯一性的验证，直至生成的S具有唯一性。
3)有效货币，在本申请实施例中主要指存储在区块链中的可被持有者用于支付的货币声明C对应的货币。
4)无效货币，在本申请实施例中主要指存储在区块链中的已被持有者支付(已被消耗)的，以及还未成功铸币(还未激活)的货币。

下面结合附图通过漫游交易前，漫游交易时，漫游交易后三个阶段对本申请提供一种基于区块链支持漫游业务的方法进行具体说明。
阶段一：漫游前。
本申请实施例中所述漫游运营设备与所述归属运营设备进行漫游交易之前，所述漫游运营设备与所述归属运营设备需要确定进行漫游交易的漫游协议以及其他必要的信息。其中，所述漫游协议用于确定话单文件对应的漫游费用，即所述漫游运营设备基于所述漫游协议确定所述归属运营设备对应的终端设备在所述漫游网络中产生的话单文件的漫游费用。同时，所述归属运营设备还可以根据所述漫游协议核对所述漫游运营设备发送的话单文件对应的漫游费用的准确性。
本申请实施例中，所述漫游运营设备与所述归属运营设备签订的所述漫游协议存储方式可以有多种，具体并不限于下述几种。
存储方式1：所述漫游协议存储到所述区块链中，所述漫游运营设备与所述归属运营 设备可根据所述漫游协议在所述区块链的存储地址，获取所述漫游协议。
存储方式2：所述漫游协议可以分别存储到所述漫游运营设备与所述归属运营设备中，所述漫游运营设备与所述归属运营设备可以分别从本地获取所述漫游协议。
本申请实施例中，所述漫游运营设备与所述归属运营设备之间协商所述漫游协议的方式可以有多种，具体并不限于下述几种。
协商方式1：如图3所示，所述漫游协议由所述漫游运营设备与所述归属运营设备之间两两制定。
示例性的，当所述漫游运营设备与所述归属运营设备共同协商确定所述漫游协议后，将所述漫游协议明文记录在区块链中。
其中，所述漫游协议附有所述漫游运营设备与所述归属运营设备的双重签名，所述漫游协议附有的双重签名用于确定签名双方承认所述漫游协议的规定。例如，漫游协议1附有的双重签名为漫游运营设备A与归属运营设备B的签名，则确定所述漫游运营设备A与所述归属运营设备B互相都认可所述漫游协议1中的规定。
因此，当漫游运营设备A与归属运营设备B之间产生漫游业务，需要确定漫游费用时，所述漫游运营设备A根据所述漫游协议1确定所述归属运营设备需要支付的漫游费用，而所述归属运营设备B则可根据所述漫游协议1核算所述漫游业务对应的漫游费用。
其中，本申请实施例在所述协商方式1中，为有效增强漫游业务的安全性，可将所述漫游协议附有的所述漫游运营设备与所述归属运营设备的双重签名进行加密。也就是说，只有对所述加密后的双重签名进行解密，才能确定所述漫游协议对应的漫游运营设备与归属运营设备，能够有效的保障了漫游业务的安全性。
进一步的，本申请实施例中，可将用于对加密后的所述双重签名进行解密的签名密钥通过BCHF安全记录在所述区块链中；或者可将用于对加密后的所述双重签名进行解密的签名密钥存储在各自对应的账单域BD中。
进一步的，在进行漫游业务中，若漫游协议明文存储在第三方平台，例如区块链中，则其他设备都有可能获取所述漫游协议，由此将产生安全隐患。为解决这一问题，本申请实施例所述漫游运营设备与所述归属运营设备之间共同确定所述漫游协议后，将所述漫游协议进行哈希或进行加密，然后将所述漫游协议的哈希结果或者加密后的漫游协议存储在所述区块链中。
需要说明的是，本申请实施例中所述漫游运营设备与所述归属运营设备都可以对所述漫游协议进行哈希或加密，且所述漫游运营设备与所述归属运营设备对所述漫游协议进行哈希或者加密的后的结果相同，为此，本申请实施例不限定对所述漫游协议进行哈希或者加密的设备。
同理，本申请实施例中所述漫游运营设备与所述归属运营设备都可以对所述双重签名进行哈希或加密，且所述漫游运营设备与所述归属运营设备对所述双重签名进行哈希或者加密的后的结果相同，为此，本申请实施例不限定对所述双重签名进行哈希或者加密的设备。
其中，所述漫游协议可以附有所述归属运营设备与所述漫游运营设备的双重签名，本申请实施例中为有效保护所述区块链中存储的所述漫游协议以及所述双重签名的安全性，可以有多种操作方式，具体并不限于下述几种：
操作方式1：将漫游协议A进行哈希或者加密，得到漫游协议A′；将所述归属运营设备与所述漫游运营设备的双重签名进行哈希或者加密，得到双重签名A′；将附带所述双重签名A′的所述漫游协议A′存储到区块链中。
其中，本申请实施例不区分确定漫游协议A′和确定双重签名A′的先后顺序，例如，本申请实施例中可同时确定所述漫游协议A′和所述双重签名A′；可先确定所述漫游协议A′，再确定所述双重签名A′；还可先确定所述双重签名A′，然后再确定所述漫游协议A′。
操作方式2：将漫游协议A与双重签名共同进行哈希或者加密，得到所述漫游协议与所述双重签名整体的哈希结果或加密结果；然后将所述哈希结果或者加密结果存储在所述区块链中。
其中，本申请实施例中若选择对所述漫游协议进行哈希，将所述哈希结果存储到区块链中，则在所述漫游运营设备与所述归属运营设备上保存了所述漫游协议。
本申请实施例中若选择对所述漫游协议进行加密，则所述漫游运营设备与所述归属运营设备在各自的账单域BD中安全存储用于解密所述加密结果的密钥。
协商方式2：所述漫游协议由所述漫游运营设备一方单独制定，并记录到所述漫游运营设备与所述归属运营设备对应的区块链上；或所述漫游协议由所述归属运营设备一方单独制定，并记录到所述归属运营设备与所述漫游运营设备对应的区块链上。而未制定所述漫游协议的另一方运营设备，根据自身情况决定是否调用该漫游协议来与另一设备建立漫游关系。
其中，所述归属运营设备或所述漫游运营设备可通过所述归属运营设备自身的BCHF将所述漫游协议记录在所述区块链中，且存储到所述区块链中的漫游协议附有制定者的签名。例如，若所述漫游协议由所述归属运营设备制定，则存储到所述区块链中的漫游协议附有所述归属运营设备的签名。
示例性的，假设所述漫游协议由所述归属运营设备一方单独制定，并将所述漫游协议存储到所述区块链中。当所述漫游运营设备与所述归属运营设备需要进行漫游业务时，所述漫游运营设备可从所述区块链中获取所述归属运营设备存储的所述漫游协议，根据所述漫游协议确定所述归属运营设备在进行所述漫游业务时所产生的漫游费用。
其中，所述漫游运营设备可根据所述归属运营设备在需要进行漫游业务时发送的漫游协议在区块链中的存储地址，从所述区块链中获取所述漫游协议，即所述漫游运营设备获取到的所述漫游协议在所述区块链中的存储地址，是在需要进行漫游业务时所述归属运营设备发送给所述漫游运营设备的；或所述漫游运营设备根据与所述归属运营设备事先约定的漫游协议存储地址，从所述区块链中获取所述漫游协议，即所述漫游运营设备与所述归属运营设备事先约定所述漫游协议由所述归属运营设备一方制定，且所述归属运营设备将所述漫游协议在所述区块链中的存储地址事先通知所述漫游运营协议，后续在进行漫游业务时，所述漫游运营设备可直接根据事先约定的所述漫游协议在所述区块链中的存储地址，获取所述漫游协议。
其中，本申请实施例在所述协商方式2中，为有效增强漫游业务的安全性，可将漫游协议B进行加密，得到漫游协议B'；将所述归属运营设备或所述漫游运营设备一方的单方签名进行哈希或者加密，得到单方签名B'。然后，将附带所述单方签名B'的所述漫游协议 B'存储到区块链中。需要说明的是，本申请实施例不区分确定漫游协议B'和确定单方签名B'的先后顺序。
进一步的，本申请实施例中所述漫游运营设备和/或所述归属运营设备在各自的账单域BD中安全存储用于解密加密结果的密钥。
进一步的，本申请实施例中，无论哪一种协商方式，所述漫游运营设备与所述归属运营设备在确定用于进行漫游交易的漫游协议后，所述归属运营设备和所述漫游运营设备之间根据所述漫游协议确定进行漫游交易过程中的漫游资费信息。所述漫游运营设备可以根据所述漫游协议针对不同类型的UE，确定需要提供的网络保障，还可以根据所述漫游协议确定向所述归属运营设备提供的漫游话单的格式。
进一步的，所述归属运营设备根据所述漫游协议中的用于确定漫游费用的参数信息确定所述漫游运营设备提供给自己的漫游费用标准，从而结合自身的运营成本，针对不同类型的UE制定对应的漫游零售资费，或漫游话费套餐。
本申请实施例一种实现方式中，如图3所示，所述归属运营设备中的账单域BD向所述归属运营设备中的统一数据管理UDM传递所述漫游协议中用于确定漫游费用的参数。所述UDM根据所述参数信息确定所述漫游运营设备提供给自己的漫游费用标准，从而结合自身的运营成本，针对不同类型的UE制定对应的漫游零售资费，或漫游话费套餐。
其中，本申请实施例中采用哈希的方式对所述签名和/或所述漫游协议进行保护，能够更加简单高效的进行信息的隐藏，并且由于哈希算法是安全可公开的，在需要获取部分文件时，并不会影像剩余文件的安全性和隐秘性。
阶段二：漫游时。
本申请实施例中所述漫游运营设备与所述归属运营设备在进行漫游过程中，所述漫游运营设备与所述归属运营设备的具体交互流程可以如图4所示，具体包括以下步骤：
S400：所述漫游运营设备确定所述归属运营设备阈值时长内进行漫游业务产生的话单文件。
本申请实施例一种实现方式中，所述归属运营设备在阈值时长内，在所述漫游地可产生至少一轮话单文件，相应的所述漫游运营设备可根据每轮话单文件确定所述话单文件对应的漫游费用。
示例性的，假设本申请实施例中阈值时长为X，所述漫游运营设备与所述归属运营设备在所述X时长内，进行了三轮漫游业务，则对应会产生三轮话单文件。所述三轮话单文件按时间先后顺序分别为话单文件1、话单文件2和话单文件3。
其中，所述漫游运营设备中的SMF通过计费触发功能CTF向所述漫游运营设备中的CHF发送每轮话单文件。所述CHF整理所述SMF提供的至少一轮话单文件后(例如三轮话单文件)，根据所述漫游协议(例如漫游协议中的话单分段格式、话单记录内容等)，整理出所述X时长内的话单文件并发送至所述漫游运营设备的BD。
S401：所述归属运营设备确定所述阈值时长内在所述漫游地网络进行漫游业务产生的话单文件。
本申请实施例一种实现方式中，所述归属运营设备在阈值时长内，在所述漫游地可产生至少一轮话单文件，例如，假设本申请实施例中阈值时长为X，所述漫游运营设备与所述归属运营设备在所述X时长内，进行了三轮漫游业务，则对应会产生三轮话单文件。
所述三轮话单文件按时间先后顺序分别为话单文件1、话单文件2和话单文件3。其中，所述归属运营设备中的SMF分别向所述归属运营设备中的CHF发送每轮话单记录。所述CHF整理所述SMF提供的至少一轮话单文件后，根据所述漫游协议(例如漫游协议中的话单分段格式、话单记录内容等)，整理出当前所述时段的话单文件并发送至所述归属运营设备的BD。
需要说明的是，本申请实施例中，上述S400与S401并不区分先后顺序。
S402：所述漫游运营设备根据所述话单文件确定话单声明。
其中，若所述话单文件是阈值时长内进行漫游业务过程中的第一轮漫游记录，则所述话单声明包含进行签名后的所述话单文件；若所述话单文件不是阈值时长内进行漫游业务过程中的第一轮漫游记录，则如图5所示，所述话单声明包含进行签名后的所述话单文件和所述归属运营设备上一轮话单的反馈信息。
所述话单文件的反馈信息用于指示对所述话单文件的核对结果，若核对所述话单文件有效，则所述话单文件的反馈信息包括所述第二网络设备的签名。从而可以使所述漫游运营设备与所述归属运营设备进行漫游业务产生的多轮话单文件有效的进行关联，有利于进行话单文件的整体管理，方便后续对话单文件的调取以及追溯。
本申请实施例一种可选的实施方式中，为了保证所述话单声明的安全性，可对所述话单声明进行加密或哈希。
S403：所述漫游运营设备根据所述漫游协议确定每轮话单文件对应的漫游费用，并根据所述漫游费用生成货币声明。
具体的，所述漫游运营设备根据所述漫游费用生成相应额度的货币声明和所述货币声明对应的货币验证信息。
示例性的，假设阈值时长内，共生成三轮话单文件，分别为话单文件1-3，则所述漫游运营设备根据所述漫游协议可分别确定每轮话单文件对应的漫游费用。例如，话单文件1对应的漫游费用为漫游费用1、话单文件2对应的漫游费用为漫游费用2、话单文件3对应的漫游费用为漫游费用3。
进一步的，所述漫游运营设备根据所述漫游费用1-3生成相应额度的货币声明和所述货币声明对应的货币验证信息。例如，所述漫游运营设备根据所述漫游费用1生成(C1，S1，r1)、根据所述漫游费用1生成(C2，S2，r2)、根据所述漫游费用1生成(C3，S3，r3)。即所述货币声明C1用于表示话单文件1对应的漫游费用，所述货币声明C2表示话单文件2对应的漫游费用，所述货币声明C3表示话单文件3对应的漫游费用。
S404：所述漫游运营设备将每轮话单文件对应的货币声明和话单声明存储在所述区块链中，并记录货币声明和话单声明在所述区块链中的存储地址，将所述货币验证信息安全存在所述漫游运营设备的BD中。
S405：所述漫游运营设备将所述话单文件以及所述货币声明在所述区块链中的存储地址发送给所述归属运营设备。
可选的，所述漫游运营设备可将所述话单文件以及所述货币声明发送给所述归属运营设备；
可选的，所述漫游运营设备可将包含所述货币声明存储地址的所述话单文件发送给所述归属运营设备。
S406：所述归属运营设备进行话单文件验证。
本申请实施例中，所述归属运营设备进行话单验证时，可分为两种情况：
情况1：在归属网络路由(home routed)模式下，所述归属运营设备在已经获得了本地记录的话单文件的前提下，确定接收到的所述漫游运营设备发送的话单文件和本地记录的话单文件之间是否基本匹配；所述归属运营设备根据接收到的所述货币声明的在所述区块链中的地址信息，获取所述区块链上存储的对应货币声明，确定是否符合漫游协议，以及查看所述区块链中交易声明中的话单文件是否符合所述漫游运营设备发送的话单文件。
情况2：在本地路由(local breakout)中，所述归属运营设备根据接收到的所述货币声明的在所述区块链中的地址信息获取所述区块链上存储的对应货币声明，确定是否符合漫游协议，以及查看所述区块链中交易声明中的话单文件是否符合所述漫游运营设备发送的所述话单文件话单的哈希结果。
其中，本申请实施例中为保证话单文件的安全性，所述区块链中存储的话单文件为加密或哈希后的话单文件，所述漫游运营设备发送给所述归属运营设备的话单文件也为加密或哈希后的话单文件。因此，在验证时，例如以哈希为例，则确定所述区块链上存储的交易记录中的已哈希后的话单文件与所述漫游运营设备发送给所述归属运营设备的所述话单文件的哈希结果是否一致。
S407：所述归属运营设备根据所述话单文件验证结果，向所述漫游运营设备发送所述话单文件的反馈信息。
其中，所述归属运营设备针对所述话单文件的验证结果不同，向所述漫游运营设备发送的所述话单文件的反馈信息也不相同，具体并不限于下述几种情况。
情况1：若所述归属运营设备通过对所述话单文件进行验证，确定所述话单文件为有效话单文件，则所述话单文件的反馈信息包括所述第二网络设备的签名。即表示所述归属运营设备认可所述话单文件。
情况2：若所述归属运营设备通过对所述话单文件进行验证，确定所述话单文件为无效话单文件，则所述话单文件的反馈信息可以包括话单文件重协商信息。即表示所述归属运营设备并认可所述话单文件，需要与所述漫游运营设备针对所述话单文件进行重新确认以及协商。
以下为归属运营设备对终端的漫游费用进行支付的步骤：
S408：所述归属运营设备选择支付的所述漫游运营设备的第一货币声明，其中，选择的所述第一货币声明为未进行支付的无效货币。
其中，本申请实施例中所述归属运营设备选择支付的所述第一货币声明的方式有多种，具体并不限于下述几种。
选择方式1：从所述漫游运营设备中未进行支付的多个货币声明中选择第一货币声明进行支付。
示例性的，假设所述区块链中存储的所述漫游运营设备的多个货币声明包括货币声明C11、货币声明C12、货币声明C13和货币声明C14。其中，所述货币声明C11-C14对应的货币都为无效货币，但是所述货币声明C11对应的货币为已支付的无效货币，所述货币声明C12-C14对应的货币为未进行支付的无效货币。因此，所述归属运营设备从所述货币声明C12-C14中选取一个货币声明C14进行支付。假设，所述归属运营设备选取的第一货币声明为货币声明C14。
选择方式2：从所述漫游运营设备中未进行支付的货币声明中选择待支付时长最久的 第一货币声明进行支付。其中，所述待支付时长可以表示为货币声明在区块链初始记录时间到当前时间的时长。
示例性的，假设所述区块链中存储的所述漫游运营设备对应的未进行支付的货币声明包括货币声明C11、货币声明C12、货币声明C13。其中，所述货币声明C11待支付时间为1s，所述货币声明C12待支付时间为2s，所述货币声明C13待支付时间为3s。因为，所述货币声明C13待支付时长最长，因此，所述归属运营设备选择所述货币声明C13进行支付，即所述归属运营设备选取的第一货币声明为货比声明C13。
选择方式3：所述归属运营设备根据自身所持有的有效的第二货币声明，选择支付的所述第一货币声明。其中，选择标准可以为选择的所述第一货币声明的金额小于或等于所述第二货币声明的金额。
S409：所述归属运营设备从自身持有货币声明中选取第二货币声明，用于支付选择的第一货币声明，所述第二货币声明为所述归属运营设备自身持有的有效货币声明。
其中，所述归属运营设备选取的所述第二货币声明对应的面额不小于选择的所述第一货币声明的面额。
示例性的，假设所述归属运营设备选择支付的所述第一货币声明为货币声明C14，所述货币声明C14对应的货币的面额为“100”。所述归属运营设备自身持有的第二货币声明包括货币声明C21-C25，且对应的货币面额都为“50”。
因此，所述归属运营设备可从自身持有的货币声明C21-C25中选取两个货币声明C用于支付所述货币声明C14。例如，所述归属运营设备选取自身持有的货币声明C22和货币声明C25用于支付所述货币声明C14。
S410：所述归属运营设备完成支付后，生成对应的支付的完成信息。
可选的，所述支付的完成信息用于指示所述归属运营网络设备对选取的第一货币声明支付完成，所述支付的完成信息包括用第二货币声明进行支付的交易地址。
可选的，本申请实施例中所述支付完成消息包括所述归属运营设备选择的所述货币声明对应的隐私序列号S和零知识证明zkp，本申请实施例可根据所述zkp确定所述货币声明，例如所述货币声明C对应的隐藏随机值r，使得f(S,r)＝C。
进一步的，本申请实施例中，所述归属运营商设备的所述货币声明C的值不会被暴露，且所述货币声明C对应的所述隐私序列号S在区块链中从未被记录过，即所述货币声明C对应的货币未被使用过。
进一步的，所归属运营设备中的零知识证明可直接关联选取的所述漫游运营设备的货币声明C的唯一标识信息，其中，所述唯一标识信息可以为所述货币声明C本身或所述货币声明C在所述区块链中的存储地址。
进一步的，所述归属运营设备中的零知识证明关联对应的话单声明。因为若所述话单声明对应的话单文件不是阈值时长内第一轮话单文件，则所述话单声明中还会包括所述归属运营设备上一轮反馈的支付的完成信息，因此，通过S410的关联，可将所述阈值时长内的整个漫游过程中存在的多轮话单文件彼此关联起来。从而在后续进行追溯、问责的时候可以获取完整的漫游事件。
S411：所述归属运营设备将生成的所述支付的完成信息发送给所述区块链。
可选的，本申请实施例中将所述支付的完成信息在所述区块链中的存储地址记录下来，从而后续将所述支付的完成信息在所述区块链中的存储地址发送给所述漫游运营设备，以 使所述漫游运营设备通过所述支付的完成信息在所述区块链中的存储地址，查询区块链记录进行验证。
S412：所述区块链对所述支付的完成信息进行有效性审核。
其中，本申请实施例中，所述区块链主要通过下列方式确定所述支付的完成信息有效：
所述区块链确定所述归属运营设备选取的所述第二货币声明的面额不大于所述归属运营设备选取的所述第一货币声明的面额；所述区块链确定所述归属运营设备选取的所述第一货币声明对应的所述隐私序列号S并未在有效历史交易记录中被使用；所述区块链确定所述归属运营设备选取的所述第一货币声明对应的货币为有效货币。
S413：当所述区块链确定所述支付的完成信息有效后，则所述区块链将本次支付的完成信息同步全网。
进一步的，当所述区块链确定所述支付的完成信息有效，并将本次支付的完成信息同步全网后，也意味着所述漫游运营设备之前初始铸币过程中所记录的对应的货币声明生效，由无效货币变为有效货币，铸币完成。
S414：所述归属运营设备向所述漫游运营设备反馈支付的完成信息。
可选的，所述归属运营设备还可以将所述支付的完成信息在所述区块链中的存储地址发送给所述漫游运营设备。
其中，本申请实施例中，所述归属运营设备向所述漫游运营设备反馈的支付的完成信息为本轮完成的话单文件的签名，以表示所述归属运营设备通过对本轮话单文件的核对，还需要包括所述归属运营设备选取的所述第一货币声明在区块链中的记录地址，以方便所述漫游运营设备进行查询。
可选的，本申请实施例中，所述反馈信息中还可包含其他信息，例如存在漫游服务修改的UE信息、资费纠纷信息等。
需要说明的是，本申请实施例中，每一轮结束之后，在所述归属运营设备的本地和所述漫游运营设备的本地都会具有相同的话单文件明文以及双方的签名。其中，所述漫游运营设备的签名主要针对本轮话单文件；所述归属运营设备的签名主要针对上轮话单。
可选的，本申请实施例中，所述归属运营设备与所述漫游运营设备双方同时安全缓存话单文件的详细内容，直至对应的话单文件不会存在仲裁需求。
S415：所述漫游运营设备向所述区块链查询所述第一货币声明对应的支付交易，确定所述第一货币声明对应的货币为有效货币。
其中，本申请实施例中所述漫游运营设备在所述区块链中存储的所述第一货币声明对应的货币从无效货币变成有效货币后，则证明所述漫游运营设备铸币成功，在后续的漫游交易中，所述漫游运营设备可以使用所述第一货币声明对应的货币进行支付。
阶段三：漫游后。
本申请实施例中当完成漫游费用支付和话单文件交易之后，可根据双方是否存在异议，分为多种情况。
情况1：若所述漫游运营设备与所述归属运营设备双方不存在异议，则本次漫游业务终止。
可选的，本申请实施例中为节省区块链以及漫游运营设备与归属运营设备的存储空间，在所述漫游运营设备与所述归属运营设备完成漫游业务且双方不存在异议时，可删除所述区块链和/或双方设备中存储的冗余文件。
情况2：若所述漫游运营设备与所述归属运营设备双方或某一方存在异议，则如图6所示，所述漫游运营设备和/或所述归属运营设备可进行仲裁。
进一步的，本申请实施例中，若所述归属运营设备和/或所述漫游运营设备进行仲裁时，仲裁申请方需要出示有效的话单内容来维护自身权益。
本申请实施例一种实现方式中，发起仲裁申请的仲裁申请方的BD向仲裁方发送仲裁申请消息，其中，所述仲裁申请消息包括：待仲裁的话单文件、所述话单文件在区块链中的存储位置、下一轮话单文件中归属运营设备给出的签名。
其中，若本申请实施例中涉及到所述归属运营设备的签名，则所述仲裁申请消息中还需要包括下一轮的相关内容，以保证所述归属运营设备的签名是在漫游服务过程中时时记载在区块链中。
可选的，本申请实施例中，从隐私保护角度出发，所述区块链记录的所有话单文件都只为将所述话单文件进行哈希后的哈希结果。而本申请实施例中仲裁申请方在进行仲裁时，需要向第三方仲裁者证明在所述区块链中已记录的哈希结果里面包含了需要仲裁支持的信息，例如，仲裁申请方声称在某一时间，提供过什么服务。
因此，发起仲裁申请的仲裁申请方的BD向仲裁方发送的仲裁申请消息包括：待仲裁话单文件及用于对所述话单文件在所述区块链中对应的所述哈希结果进行验证的验证信息、所述话单文件在区块链中的哈希结果的存储位置。
进一步的，本申请实施例中所述仲裁方根据所述仲裁申请消息中的所述话单文件在所述区块链中的存储位置从所述区块链中获取所述区块链存储的所述话单文件信息，并验证所述话单文件信息的完整性。
其中，一种实现方式中，本申请实施例中所述仲裁方可根据下列方式验证所述话单文件信息的完整性：
首先，根据公开的哈希算法确认记录在区块链中的话单声明记录的确为待仲裁内容的哈希结果，确保生成话单的真实存在性；其次，验证签名的正确性，确保记录在区块链上的话单记录在当时是受到交易双方的认同的。
以上验证均通过后，仲裁方确信所述仲裁申请方的BD出示的是真实有效的话单信息，则所述仲裁方根据已定的漫游合约以及当地法律法规对漫游事件进行仲裁。
通过上述对本申请方案的介绍，可以理解的是，上述实现各设备为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
