Basic description of SMS server

1.SmsGate: used to respond to the connection request of the client program, receive the short message (MT) sent by the client program, inform whether the short message has been reported to the mobile phone user, and forward the short message (MO) to the client.

2.Mo (mobile origin): SMS initiated by mobile phone users.

4. Report: The operator will return the status report of whether the mobile phone user has received the SMS or the monthly bill.

5. Monthly bill: for monthly information, after the user's subscription relationship is confirmed (72 hours), a bill will be issued once a month to charge it.

6. Short connection: When sending a short message, the client program connects with the Gate, and hangs up after sending a message. This method is suitable for embedding sending function in web pages. This method cannot receive reports and production tasks.

7. Long connection: The client program always keeps the connection with the Gate. This method can receive reports and MO, and clients need to develop programs based on communication API.

8. Business type: SMS content services can be mainly divided into two types: on-demand and subscription. On-demand service happens randomly, and users need information temporarily when they need it, which is a one-time service relationship. Subscription information is customized by users, and service providers send the same information to all subscribers on time.

9. Service number: Each short message sent to the user must belong to a service declared by the operator. The service number uniquely identifies a service and also determines the information fee (including the free case). When sending SMS, you need to mark the number of the service.

10, sub-number: interconnection assigns each user a user id, password and sub-number, and users can conduct business on the basis of this sub-number. This sub-number is added to the special service number of the Internet to form the unique service number of the user. Users can continue to add numbers after sub-numbers. At present, the total length (including the sub-sign) is limited to 8 digits. Users only need to care about the child number when sending and receiving, and do not need to care about the Internet service number.

1 1. Third-party payment: Some services provided by users may be requested by others, such as: A mobile phone users request messages for B mobile phone users and write short messages themselves. In this way, mobile phone B is the receiver, but the payer is A, that is, the third party pays. By default, a paying phone is a receiving phone. If the payment is made by a third party, please indicate the payment mobile phone when sending.

12. User registration: Mobile phone users need to register before applying for using information services provided by service providers. Mobile phone users should be verified when registering, and the registration is successful after verification.

13. User subscription: each service must be subscribed by the user in person before the subscription relationship can take effect. If it is on-demand through upstream information, the on-demand service can take effect immediately. If it is on-line, it needs to be a registered user. According to the requirements of operators, we must keep the complete subscription relationship of each user, and the subscription information will be sent according to our subscription relationship here. The user only needs to provide the sent information.
