Its most important feature is to provide various value-added services in a fast, convenient, flexible and economical manner. As an important service in the prepaid intelligent service, the USSD application service has developed rapidly in recent years, especially as the OCS (Online Charging System) business has developed many new business functions. The SP (Service Provider) value-added service provides users with more and more intelligent services, and has also achieved significant economic benefits for operators.
USSD应用业务由于其方便、 快捷、 和安全性等优点已经得到了越来越 多的推广应用， 特别是 SP增值服务， 比如代缴费服务、 银行服务、 和股票 服务等等， 极大地方便了广大用户的同时， 也增加了运营商的经济效益。 但 是， 针对越来越多的 SP应用服务， 各个 SP提供的内容是不相同的， 各 SP 要求的接入流程也不相同，传统的做法是： SP的接入流程一般放在 SP侧（包 括 SP服务器），

USSD应用业务的菜单中的各个功能选项对应的功能交互流程； 配置各个功 能交互流程中的需要获取的参数和参数校验方式； USSD中心根据选择的功 能选项， 与用户设备进行对应于选择的功能选项的功能交互流程以向用户设 备获取参数还包括： USSD中心与用户设备进行预先配置的与选择的功能选 项对应的功能交互流程； 在功能交互流程中， USSD中心才艮据预先配置的需 要获取的参数， 依次向用户设备查询参数； 在查询得到全部的参数后， USSD 中心使用预先配置的参数校验方式对全部的参数进行校验。 优选的， USSD中心与 SP 艮务器通过预先配置的可扩展标签语言 XML 协议定义的接口进行通信。 优选的， 在 USSD中心将 USSD应用业务的菜单发送给用户设备进行选 择之前，还包括： 逐级地配置菜单以及菜单中的内容；在 USSD中心将 USSD 应用业务的菜单发送给用户设备进行选择之后， 还包括： USSD中心根据预 先配置的菜单及其内容， 通过与用户设备的一次或多次交互获得功能选项。 根据本发明的另一方面， 提供了一种 USSD中心， 包括： 第一接收模块， 用于接收来自用户设备的请求消息， 其中， 请求消息中包括服务提供商 SP 提供的 USSD应用业务的接入码； 获取模块， 用于与用户设备进行交互， 获 取用户设备请求执行的功能操作以及执行功能操作所需的参数； 参数发送模 块， 用于将获取到的参数和请求消息发送给 SP服务器； 结果发送模块， 用 于将来自 SP服务器的执行结果发送给用户设备。 优选的， 获取模块包括： 菜单发送模块， 用于才艮据接入码， 将 USSD应 用业务的菜单发送给用户设备进行选择； 参数获取模块， 用于根据用户设备 选择的菜单中的功能选项，

查询到上述账号中的余额后， 将查询到的余额通过 USSD中心发送给该用户设备。 该实施例中， 由 USSDC完成全面的接入流程控制和参数处理， 当接入 流程处理完毕后， 把请求消息和收集到的参数等相关信息一起送给 SP服务 器， 由 SP服务器完成对请求的结果处理， 即 USSDC相当于是 SP服务器的 前置机， 负责完成全部的接入控制功能， 而 SP服务器只需要完成最后的数 据处理并返回结果即可。 从而， 充分利用了 USSDC的强大的交互功能， 能 够实现较为复杂的 USSD应用业务， 比如需要用户设备交互多次才能完成一 次操作， 解决了相关技术中存在的无法实现较为复杂的 USSD应用业务的问 题。 由于上述实施例的方法中， USSDC相当于是 SP服务器的前置机， 因此 也可以称为前置处理模式的 USSD应用业务的实现方法。 优选地， 步骤 S 104包括： 步骤

SP的菜单推送给用户终端， 以便获得用户终端请求执行的功能操作， 并 进一步向用户终端获取执行该功能操作所需的所有参数。 优选地， 上述步骤 1包括： USSD中心解析出步骤 S 102中接收到的请求 消息中的接入码， 并确定该接入码属于某一个 SP提供的 USSD应用业务； USSD中心从本地查找到对应于该 SP提供的该 USSD应用业务的菜单 （也 称为应用菜单）； USSD中心将查找到的菜单发送给该用户设备以供该用户设 备从该菜单中选择所需的功能选项。 该优选实施例提供了 USSDC将本地保存的对应于该接入码的 SP的应用 菜单推送给用户设备以供其进行选择的具体实施方案。这样， USSDC接收到 用户设备的请求消息后， 不再转发给对应的 SP的 SP服务器， 而是直接将本 地保存的对应菜单推送给用户设备， 从而利用了自身的强大的交互功能， 无 需 SP服务器执行该操作， 节约了 SP服务器的资源和性能。 优选地， 步骤 2中： USSD中心根据用户设备所选择的菜单中的功能选 项向该用户设备获取执行该功能选项对应的功能操作所需要的参数的步骤包 括： USSD中心接收到来自用户设备的携带有该用户设备从该菜单中所选择 的功能选项的消息； USSD中心根据该功能选项， 与该用户设备进行对应于 该功能选项的功能交互流程以向该用户设备获取上述参数。 上述 USSD中心 的参数收集的过程同样充分利用了 USSD中心自身的强大的交互功能， 无需 SP服务器执行该操作， 节约了 SP服务器的资源和性能。 优选地， 步骤 2中： USSD中心将获取到的参数和该请求消息发送给 SP 服务器包括： 该功能交互流程结束后， USSD中心将获取到的执行该功能选 项对应的功能操作所需的全部参数发送给该 SP对应的 SP 艮务器。 这样， 在 获取到所有参数后， 将请求消息和所有参数一起发送给对应的 SP服务器， 从而无需 SP服务器执行接入流程控制和参数收集处理， 实现了在 USSD应 用中，根据 SP接入流程的特点，可以适应多 SP个性化接入应用，能让 USSDC 艮好地处理各种 SP的接入请求，大大地增强了 USSDC的交互功能和控制功 匕 在实际实施时， 如图 2所示， 以非洲某跨国运营商基于智能网 OCS架构 的 USSD在适应多 SP接入流程上的处理实现为例， 详细说明本发明实施例 的 USSD应用业务的实现方法的业务流程， 包括以下步 4聚： 步骤 S202, 用户设备发送请求消息给 USSDC, 其中， 该请求消息中包 括 USSD接入码 * 123#； 该步骤 S202对应于图 1中的步骤 S 102 步骤 S204至步骤 S206, USSDC收到用户设备的请求消息后， 进行接入 码解析， 分析出是某 SP应用， 调出对应 SP的应用菜单推送给用户设备， 供 用户设备选择。 用户设备选择查询账户余额功能选项； 上述步骤 S204至步骤 S206对应于图 1中的步骤 S 104 步骤 S208至步骤 S216, USSDC根据用户设备的选择， 进入查询账户余 额的功能流程， 发送收集账号的消息给用户设备， 用户设备根据提示， 输入 查询账号， USSDC继续推送消息给用户设备， 请求用户设备输入密码， 用户 设备输入密码后， USSDC判断， 参数收集已经完成， 可以把该请求及参数信 息全部送给对应的 SP 艮务器处理； 上述步骤 S208至步骤 S216对应于图 1中的步骤 S 106 步骤 S218至步骤 S222, SP服务器收到用户设备请求后， 通过接入码判 断出是查询账号余额操作， 取出已经获得的查询余额的账号和密码， 进入相 关的查询余额流程， 取出对应的余额信息后， 送给 USSDC, USSDC收到成 功消息后， 将对应的余额信息发送给用户设备， 完成全部的一次用户设备操 作， 当然 SP服务器最后也可选择再发送一条余额短信给用户设备。 上述步骤 S218至步骤 S222对应于图 1中的步骤 S 108。 可以看出： 在上述如图 2所示的实施例中， 当完成全部的交互之后， 把 用户设备的选择和相关参数信息发送给 SP服务器，接受 SP服务器的响应结 果， 根据响应结果做下一步动作， SP服务器进行全部的逻辑和流程控制。 上述的实现方法增强了对 USSDC的接入功能处理的要求，因为各 SP的 接入需求是不相同的， 这样 USSDC就需要开发各种不同的接入流程， 以往 都是增加一个 SP应用， 根据 SP接入流程来开发一个对应的 USSDC处理程 序， 而本发明的下述优选实施例根据 SP接入的特点提供了通过配置来定制 接入流程的功能的技术方案， 实现了快速定制各 SP的接入流程的功能。 具 体实现分为两个部分， 一部分是接入流程控制可配置功能， 一部分是对接接 口可配置功能。 接入流程控制中， 开始推送给用户设备的是菜单选择， 当用 户设备选择到某项功能时， 进入功能控制， 功能控制阶段主要完成的是交互 功能和参数收集功能。 具体如下： The USSD application service has been promoted and applied more and more due to its convenience, speed, and security. In particular, SP value-added services, such as payment services, banking services, and stock services, have greatly facilitated the majority. At the same time, users also increase the economic benefits of operators. However, for more and more SP application services, the content provided by each SP is different, and the access procedures required by each SP are different. The traditional approach is: The SP access process is generally placed on the SP side (including The USSDC (USSD Center) only completes the access function. After receiving the request from the user equipment, the USSDC will directly send the user equipment request to the corresponding SP server using the SMPP protocol. The SP server interacts with the user device to implement the USSD application, and the SP server performs all the functions of the entire request. It can be seen that the powerful interactive function of USSDC is not used at all, and only serves as an access forwarding function. However, more and more SP applications require more complicated access procedures. For example, the user equipment needs to be interacted multiple times to complete an operation. Therefore, these complicated USSD application services cannot be implemented by using the above conventional methods.

Preferably, the USSD center obtains parameters required for performing the function operation corresponding to the function option to the user equipment according to the function option in the menu selected by the user equipment, including: the USSD center receives the user equipment from the user equipment and selects from the menu. The message of the function option; the USSD center performs a function interaction process with the user device corresponding to the selected function option according to the selected function option to acquire parameters from the user device. Preferably, the USSD center sends the obtained parameters and the request message to the SP server. After the function interaction process ends, the USSD center sends all the parameters required for performing the function operation to the SP server corresponding to the SP. Preferably, before the USSD center obtains parameters from the user equipment, the method further includes: configuring a function interaction process corresponding to each function option in the menu of the USSD application service of the SP; configuring parameters and parameter verifications to be acquired in each function interaction process The USSD center performs a function interaction process corresponding to the selected function option with the user equipment to obtain parameters from the user equipment according to the selected function option. The method further includes: the USSD center and the user equipment perform pre-configured functions corresponding to the selected function option. Interaction process; In the function interaction process, the USSD center only needs pre-configured needs. The parameters to be obtained are queried to the user equipment in turn; after the query obtains all the parameters, the USSD center uses the pre-configured parameter verification method to verify all the parameters. Preferably, the USSD Center communicates with the SP server through an interface defined by the pre-configured Extensible Label Language XML protocol. Preferably, before the USSD center sends the menu of the USSD application service to the user equipment for selection, the method further includes: configuring the menu and the content in the menu step by step; and sending the menu of the USSD application service to the user equipment for selection after the USSD center selects Also included: The USSD Center obtains functional options through one or more interactions with the user device based on pre-configured menus and their contents. According to another aspect of the present invention, a USSD center is provided, including: a first receiving module, configured to receive a request message from a user equipment, where the request message includes access to a USSD application service provided by a service provider SP a module, configured to interact with the user equipment, obtain a function operation requested by the user equipment, and perform parameters required for performing the function operation; and a parameter sending module, configured to send the obtained parameter and the request message to the SP server; And a sending module, configured to send an execution result from the SP server to the user equipment.

FIG. BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. 1 is a flowchart of a method for implementing a USSD application service according to an embodiment of the present invention, including the following steps: Step S102: A USSD center receives a request message from a user equipment, where the request message is The access code of the USSD application service provided by the one SP is included; Step S104: The USSD center interacts with the user equipment to obtain a function operation requested by the user equipment and parameters required for performing the function operation; for example, the user equipment The function operation requested to be executed is to query the balance, and the USSD center obtains all parameters, such as an account number and a password, required for the function operation of performing the inquiry balance to the user equipment. Step S106: The USSD center sends the obtained parameter and the request message to the SP server. Step S108, the SP server performs the foregoing function operation according to the access code in the request message and the foregoing parameter, and passes the execution result. The USSD center sends the user equipment. For example, the SP server performs the above-mentioned query balance operation, and after querying the balance in the above account, the queried balance is sent to the user equipment through the USSD center. In this embodiment, the USSDC completes the complete access flow control and parameter processing. After the access process is processed, the request message and the collected parameters are sent to the SP server together, and the SP server completes the request. The result processing, that is, USSDC is equivalent to the front-end machine of the SP server, responsible for completing all access control functions, and the SP server only needs to complete the final data processing and return the result. Thus, taking full advantage of the powerful interactive features of USSDC, A complex USSD application service can be implemented. For example, the user equipment needs to be interacted multiple times to complete an operation, and the problem of the USSD application service that cannot be implemented in the related technology is solved. In the method of the foregoing embodiment, the USSDC is equivalent to the front-end of the SP server, and thus may also be referred to as a method for implementing the USSD application service in the pre-processing mode. Preferably, the step S104 includes: Step 1: The USSD center sends a menu of the USSD application service to the user equipment for selection according to the access code in the received request message. Step 2: The USSD center according to the user terminal The function option in the selected menu acquires the parameters required for the user device to perform the function operation corresponding to the function option. The preferred embodiment provides a specific implementation of the USSDC obtaining the functional operations requested by the user terminal and the parameters required to perform the functional operations. The US SDC can push the menu of the locally saved corresponding SP to the user terminal, so as to obtain the function operation requested by the user terminal, and further obtain all parameters required for performing the function operation to the user terminal. Preferably, the step 1 includes: the USSD center parses the access code in the request message received in step S102, and determines that the access code belongs to a USSD application service provided by a certain SP; The menu of the USSD application service (also referred to as an application menu) provided by the SP; the USSD center sends the found menu to the user equipment for the user equipment to select a desired function option from the menu. The preferred embodiment provides a specific implementation in which the USSDC pushes a locally saved application menu of SPs corresponding to the access code to the user equipment for selection. In this way, after receiving the request message of the user equipment, the USSDC does not forward the request to the SP server of the corresponding SP, but directly pushes the locally saved corresponding menu to the user equipment, thereby utilizing its own powerful interactive function, without the SP server. By doing this, the resources and performance of the SP server are saved. Preferably, in step 2, the step of the USSD center acquiring the parameters required for performing the function operation corresponding to the function option according to the function option in the menu selected by the user equipment comprises: the USSD center receiving the carrying from the user equipment There is a message of the function option selected by the user equipment from the menu; according to the function option, the USSD center performs a function interaction process corresponding to the function option with the user equipment to acquire the parameter from the user equipment. The parameter collection process of the above USSD center also makes full use of the powerful interactive functions of the USSD center itself, and does not require the SP server to perform the operation, thereby saving the resources and performance of the SP server. Preferably, in step 2, the USSD center sends the obtained parameters and the request message to the SP server, including: all parameters required for the function operation corresponding to the function option selected by the USSD center after the function interaction process ends Send to the SP server corresponding to the SP. In this way, after all the parameters are obtained, the request message and all the parameters are sent to the corresponding SP server, so that the SP server is not required to perform the access flow control and the parameter collection processing, and the USSD application is implemented according to the SP access process. Features, can adapt to multiple SP personalized access applications, can allow USSDC to handle various SP access requests, greatly enhance the USSDC interactive functions and control functions in actual implementation, as shown in Figure 2, The process of implementing the USSD application service in the embodiment of the present invention is as follows. The following describes the process of implementing the USSD application service in the embodiment of the present invention. Step S202: The user equipment sends a request message to the USSDC, where the request message includes a USSD access code*123#; the step S202 corresponds to step S102 to step S204 to step S206 in FIG. After requesting the message, the access code is parsed, and the SP application is analyzed, and the application menu corresponding to the SP is called and pushed to the user equipment for selection by the user equipment. The user equipment selects the query account balance function option; the above steps S204 to S206 correspond to step S104 to step S208 to step S216 in FIG. 1, and the USSDC enters a function flow for querying the account balance according to the user equipment selection, and sends a message for collecting the account number. To the user equipment, the user equipment enters the query account according to the prompt, and the USSDC continues to push the message to the user equipment, requesting the user equipment to input the password. After the user equipment inputs the password, the USSDC determines that the parameter collection has been completed, and the request and parameter information can be sent. The corresponding SP server is processed; the above steps S208 to S216 correspond to step S106 to step S218 to step S222 in FIG. 1. After receiving the request from the user equipment, the SP server determines that the account balance operation is performed by the access code. After taking the account and password of the already obtained inquiry balance, enter the relevant inquiry balance process, and take out the corresponding balance information, and send it to the USSDC. After receiving the success message, the USSDC sends the corresponding balance information to the user equipment to complete all the One user device operation, of course, SP server Alternatively the balance send a message to another user equipment. The above steps S218 to S222 correspond to the step S108 in Fig. 1. It can be seen that, in the embodiment shown in FIG. 2, after all the interactions are completed, the user equipment selection and related parameter information are sent to the SP server, and the response result of the SP server is accepted, and the next step is performed according to the response result. Action, SP server performs all logic and flow control. The above implementation method enhances the requirements for the access function processing of the USSDC, because the access requirements of the SPs are different, so the USSDC needs to develop various access procedures, and in the past, an SP application is added, according to The SP access process is used to develop a corresponding USSDC processing program, and the following preferred embodiment of the present invention provides a technical solution for configuring the function of the access process according to the characteristics of the SP access, thereby realizing rapid customization of each SP. The function of the access process. The specific implementation is divided into two parts, one is the access flow control configurable function, and the other is the docking interface configurable function. In the access flow control, the menu selection is started to be pushed to the user equipment. When the user equipment selects a certain function, the function control is entered. In the function control phase, the interaction function and the parameter collection function are mainly completed. details as follows:
1、接入流程控制可配置功能，根据 SP的接入流程特点主要是在 USSDC 上完成信息交互和参数收集工作， 根据这样特点， 可以釆用： 1. Access flow control configurable function. According to the access process characteristics of the SP, information exchange and parameter collection are mainly performed on the USSDC. According to such characteristics, it can be used:
( 1 ) 菜单逐级可配： 在步骤 S 104之前， 还包括： 逐级地配置该菜单以 及该菜单中的内容； 在步骤 S 104之后， 还包括： USSD中心根据上述配置的 该菜单及其内容， 通过与该用户设备的一次或多次交互获得该用户设备从该 菜单中所选择的该功能选项。 通过配置， 均可完成 USSDC和用户设备交互 的菜单内容， 无论接入流程需要和用户设备交互多少次都可以通过配置菜单 完成交互流程。 所有的菜单内容和菜单之间的兆转关系都可以配置实现， 这 样通过菜单配置， 就可以完成快速定制 SP前置流程菜单功能。 在实际实施时， 菜单的配置可以如下述表 1至表 3所示： 表 1 Menuinfo 菜单信息表 (1) The menu is configurable step by step: before step S104, the method further includes: configuring the menu and the content in the menu step by step; after step S104, further comprising: the USSD center according to the menu configured according to the foregoing Content, the function option selected by the user device from the menu is obtained by one or more interactions with the user device. Through configuration, the menu content of the interaction between the USSDC and the user device can be completed. The interaction process can be completed through the configuration menu no matter how many times the access process needs to interact with the user device. All the menu contents and the mega-transition relationship between the menus can be configured, so that the menu configuration can be used to quickly customize the SP pre-process menu function. In actual implementation, the menu configuration can be as shown in Tables 1 to 3 below: Table 1 Menuinfo Menu Information Table

( 2 ) 功能交互流程和参数处理配置化。 功能交互流程是指通过菜单选 择后， 进入到某项操作控制流程中， 该流程可能需要进行参数收集工作。 这 样， 在接下来的参数处理中， 需要收集足够的用户设备参数信息， 即参数收 集， 参数收集可能是在菜单中， 也可能是功能中收集， 参数处理配置化包括： 参数收集可配置和参数校 -险可配置两个方面。 优选地， 在步骤 S 106之前， 还包括： 配置各个 SP的 USSD应用业务的 菜单中的各个功能选项对应的功能交互流程； 配置各个功能交互流程中的需 要获取（即收集）的参数和参数校验方式； USSDC根据用户设备所选择的功 能选项， 与该用户设备进行对应于该功能选项的功能交互流程以向该用户设 备获取上述参数包括： USSDC与该用户设备进行预先配置的与所选择的功能 选项对应的功能交互流程； 在功能交互流程中， USSDC 居预先配置的上述 需要获取的参数， 依次向该用户设备查询上述参数； 在查询得到全部的参数 后， USSDC使用预先配置的上述参数校验方式对全部的参数进行校验。显然， 在全部参数均校验成功后才将这些参数与请求消息一起发送给 SP服务器进 行处理。 在实际实施时， 比如在菜单选择流程中， 用户设备选择了查询余额的功 能选项， 则将进入查询余额功能流程， 进入该功能流程后， USSDC将根据下 述表 4和表 5联合查询， 将查询到的参数表 ( spparameter ) 中索引 ( Index ) 从小到大的消息 （ getparaminf ) 逐一推送给用户设备， 提示用户设备进一步 操作， 以完成用户设备对该功能所有参数收集工作。 表 4 spaction: sp业务功能表 (2) Functional interaction process and parameter processing configuration. The function interaction process refers to entering an operation control process after selecting through the menu, and the process may need to collect parameters. In this way, in the following parameter processing, it is necessary to collect enough user equipment parameter information, that is, parameter collection, parameter collection may be in the menu, or may be collected in the function, parameter processing configuration includes: parameter collection configurable and parameter School-risk can be configured in two ways. Preferably, before step S106, the method further includes: configuring a function interaction process corresponding to each function option in a menu of the USSD application service of each SP; configuring parameters and parameters that need to be acquired (ie, collected) in each function interaction process The USSDC performs the function interaction process corresponding to the function option with the user equipment according to the function option selected by the user equipment to obtain the foregoing parameters from the user equipment, including: the USSDC performs pre-configured and selected with the user equipment. The function interaction process corresponding to the function option; in the function interaction process, the USSDC pre-configured the above-mentioned parameters to be acquired, and then queries the user equipment for the above parameters; after the query obtains all the parameters, the USSDC uses the pre-configured parameters. The verification method verifies all the parameters. Obviously, these parameters are sent to the SP server for processing after all the parameters are successfully verified. In the actual implementation, for example, in the menu selection process, the user equipment selects the function option for querying the balance, and then enters the query balance function flow. After entering the function flow, the USSDC will jointly query according to Table 4 and Table 5 below. Index ( Index ) in the parameter table ( spparameter ) that is queried The small to large messages (getparaminf) are pushed to the user equipment one by one, prompting the user equipment to further operate to complete the collection of all parameters of the function by the user equipment.

在上述的参数处理中， 参数收集和参数检验主要是对表 5进行配置， 根 据需要增加 spparameter配置， 需要几个参数就配置几项， 顺序 （ Index ) 递 增，字段 getparaminf是用于提示用户设备输入参数的交互消息，都可以配置， 当用户设备输入后还能完成参数的校验和长度及类型的转换。  In the above parameter processing, the parameter collection and parameter check are mainly to configure Table 5, and the spparameter configuration is added as needed.
