Method for Quickly Sending Short Messages in Short Message System of Public Telephone Network

technical field

The invention relates to a short message system of a public telephone network, in particular to a method for increasing the speed of sending a short message from a short message platform of a public telephone network to a terminal.

Background technique

The public telephone network short message is a new telecommunication service, and its function is to provide short message service to the users of the public telephone network (PSTN). The method of sending short messages in the public telephone network is based on the voice channel. Every time the short message platform of the public telephone network sends a short message to a user, it needs to establish a connection with the user terminal first, and then send the short message to the terminal. , cut off the connection with the user terminal after sending. However, if every time a short message is sent, it must be completed according to the above three steps of link building, sending, and link breaking, and there will be the following problems: first, it is inefficient, because from the point of view of sending a single short message, the above-mentioned link building and The time required for the link disconnection step is longer than the delivery time. If there are many short messages sent to a user, the link needs to be established and disconnected frequently, and the efficiency is obviously very low; secondly, from the user's point of view, when he is receiving When there are multiple short messages, because each short message needs the above three steps, it will inevitably cause the prolongation of the delivery time and cause inconvenience to the user in using the terminal. Therefore, the concept of online delivery is stipulated in the short message of the public telephone network, that is, multiple short messages can be delivered once a link is established, and the steps are link establishment, delivery of short message 1, delivery of short message 2, ... delivery Short message n, broken link.

Fig. 1 is a schematic diagram of the short message system of the public telephone network. The terminal, as a short message sending and receiving device, is connected to the public telephone network through a subscriber line; the short message platform mainly includes a storage and forwarding module and a delivery module; the delivery module is used to send a short message, through the SMPP ( The Short Message Peer to Peer) protocol communicates with the store-and-forward module, and accesses the public telephone network through a relay; the store-and-forward module is used to complete the store and forward of short messages, and communicates with the delivery module through the SMPP protocol based on the TCP/IP protocol.

At present, a method for delivering short messages in the public telephone network is as follows: firstly, the short message platform establishes a connection with the user terminal, and the short message platform sends the first short message to the terminal; at the same time, the store-and-forward module in the platform tells Whether there is a follow-up short message waiting to be sent by the sending module, if the flag is present, the sending module waits for the store and forward module to send the next short message after sending the first short message; if the flag is not present, the sending module After sending the first short message, cut off the connection with the user terminal.

Although this method can increase the speed of sending short messages from the short message platform to the terminal, it has the following defects. First, this method cannot realize sending as many short messages as possible to the terminal in one connection. Because the short message sending module maintains or cuts off the connection with the terminal according to the flag value after the short message is sent, and the flag is updated when the short message is sent, when the flag is not, and the sending module is sending In the case of short messages, when the store-and-forward module receives a short message with the same destination address, the flag cannot be updated. In this way, after the short message is sent, the sending module cuts off the connection with the terminal according to the existing flag (no). In fact, there are follow-up short messages on the platform. Secondly, the investment in platform equipment has been increased. Since the platform needs to establish or disconnect the connection with the terminal frequently, the relay resources cannot be fully utilized, so the relay resources of the platform must be increased. At the same time, since the platform must temporarily store short messages, the storage capacity of the platform is increased.

Contents of the invention

The technical problem to be solved by the present invention is to provide a method for quickly sending short messages in the short message system of the public telephone network, which can make the short message platform send as many short messages as possible to the terminal after establishing a connection with the terminal once, At the same time, the investment on short message platform equipment is reduced.

The method for quickly issuing short messages of the present invention comprises the following steps:

1. The store-and-forward module in the short message platform sends a short message to the sending module;

2. The sending module establishes a connection with the terminal according to the destination address carried in the short message;

3. The sending module sends a short message to the terminal;

4. After receiving the short message, the terminal sends a delivery result message to the delivery module, and the delivery module maintains the connection with the terminal, and simultaneously forwards the delivery result message to the store-and-forward module;

5. After the store-and-forward module receives the sending result message, it checks the storage area to find whether there is a short message with the same destination address. If there is, go to step six, otherwise go to step seven;

6. The store-and-forward module sends short messages with the same destination address to the sender module, and proceeds to step 3;

7. The delivery module cuts off the connection with the terminal.

The method for sending short messages in the present invention improves the sending efficiency of short messages, and can send short messages to users as soon as possible, avoiding the backlog of short messages on the platform; at the same time, during a connection, as many messages as possible can be sent Short messages do not need to frequently occupy relay resources, and also reduce the requirements on the storage capacity of the platform.

Detailed ways

The method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in FIG. 1 , the delivery module and the store-and-forward module are two functional entities in the short message platform, and realize sending short messages to terminals. Among them, the functions completed by the sending module are: establish a connection with the terminal, send a short message to the terminal, receive the result message sent by the terminal, cut off the connection with the terminal, receive the short message sent by the store-and-forward module, send a short message to the store-and-forward module Forwarding the delivery result message, etc.; the storage and forwarding module completes the functions of temporarily storing short messages, sending short messages to the delivery module, and receiving the delivery result message forwarded by the delivery module. A short message platform can be connected to multiple terminals.

The specific flowchart of the method of the present invention is shown in FIG. 2 . After the sending module receives the short message sent by the store and forward module, it searches for the corresponding terminal according to the destination address. If the short message platform has established a connection with the terminal, then it directly sends the short message to the terminal; if the short message platform If no connection is established with the terminal, the short message platform first establishes a connection with the terminal, and then sends a short message. After the sending module receives the sending result message from the terminal, it forwards the sending result message to the store-and-forward module, and the store-and-forward module checks its storage area after receiving the forwarded sending result message. Short messages with the same address will be sent to the sending module immediately, and the sending module will continue to send short messages to the terminal, otherwise the sending module will cut off the connection between the platform and the terminal, and end this short message sending.

In a process of delivering a short message, the sending module checks the destination address of the short message after receiving the short message sent by the store and forward module. If the short message platform has established a connection with the corresponding terminal, it will directly send a short message; if the platform has not yet established a connection with the terminal, it will first establish a connection and then send a short message. After sending the short message, the sending module waits for the sending result message answered by the terminal, and forwards it to the store-and-forward module after receiving it. The specific process is shown in Figure 3.

For the store-and-forward module, after sending a short message to the down-delivery module, it waits for the delivery result message forwarded by the delivery module. After receiving the delivery result message, the store-and-forward module immediately checks whether there is any The short message with the same destination address needs to be sent, if there is, the message will be sent to the sending module immediately; if not, the short message sending will end. The specific processing flow of the store-and-forward module is shown in Figure 4.
