推荐答案

以下是您在进行 USSD 计划时希望找到答案的一些问题.

Here are some of the questions you'd like to find answers for as you proceed with your USSD plan.

•.我们希望频道如何工作?

•. How do we want the channel to work?

对于初学者来说，USSD 就像面向连接的 SMS 通信，即 USSD 之于 SMS 就像 IM 之于电子邮件.通信的发起可以是USSD-PUSH(移动终止&提供商发起)或USSD-PULL(移动发起&提供商终止).在您的情况下，我认为这可能是源自移动设备的 USSD 拉取，即移动用户在其手机上拨打 USSD 短代码以访问该应用.

For starters, USSD is just like connection-oriented SMS communication i.e, USSD is to SMS what IM is to email. The initiation of the communication can either be USSD-PUSH ( Mobile-terminated & provider originated) or a USSD-PULL (Mobile originated & provider terminated). In your case, I believe it would probably be a mobile originated USSD pull where the mobile subscriber dials a USSD short code on his mobile to access the app.

•.如果是 USSD-PULL...我们的短代码是什么?

•. If it is USSD-PULL... what is our short code?

每个应用都需要一个单独的短代码.USSD 简码是类似于互联网世界中的网站地址的站点地址方案.我不确定您来自哪个国家/地区，但在印度，USSD 短代码归移动服务提供商所有，您需要让服务提供商为您配置正确的短代码.

Every app requires a separate short code. USSD shortcodes are site addresses scheme similar to the website addresses in the internet world. I am not sure what country you are from, but here in India, USSD shortcodes are owned by the mobile service providers and one needs to get the service provider to configure the right short codes for you.

•.现在，什么是通信接口?

•. Now, what is the communication interface?

USSD 使用面向连接的 SMPP 工作.但是，USSD 网关(服务提供商拥有的中间件，可以将 USSD 消息中继到订阅者的手机和从订阅者的手机接收到的消息，现在能够充当桥梁，使他们的应用程序界面可以通过 HTTP 或 HTTPS 传输.在这种情况下，我会认为您需要在移动运营商的网关和您的应用之间打开 HTTP 或 HTTPS 连接.从那时起，只需构建带有文本响应的网络应用即可！

USSD works using a connection oriented SMPP. However, USSD gateways ( service-provider owned middle-ware that relays USSD messages to and from the subscribers' mobiles, these days are capable of acting as bridges where their app interface can be over HTTP or HTTPS. In this case, I'd think you'd need HTTP or HTTPS connectivity opened between the mobile operator's gateway and your app. From then on, it is just matter of building a web-app with a text response!
