Description

Method for Accessing Multiple Short Message Protocols on Fixed Network Short Message Platform

technical field

The present invention relates to the short message platform of public switched telephone network (PSTN), specifically, relate to the method for compatible access multiple short message protocols on the short message platform,

Background technique

In recent years, the short message service has developed rapidly. In addition to the application in the mobile communication system, the application of the short message service has also been gradually extended to the PSTN (that is, the commonly called fixed network). Fixed network short message service is divided into short message uplink and short message downlink two processes, as shown in Figure 1. Short message uplink means that terminal 1 sends a short message to the fixed network short message platform; short message downlink means that the fixed network short message platform calls terminal 2 according to the destination user address and sends the short message to terminal 2.

The fixed network short message platform can be divided into short message access module, short message service processing module, short message distribution module and short message maintenance module according to functions, as shown in Figure 2. Among them, the communication between the short message access module and the short message service processing module adopts the INAP (Intelligent Network Application Process) protocol based on TCP/IP, and the communication between the short message service processing module and the short message distribution module adopts the protocol based on TCP/IP Short message point-to-point SMPP (Short Message Peer to Peer) protocol communication.

The short message access module mainly completes the access of various terminals, uploads and sends various instructions and message data, and reports various call events and received user messages to the short message service processing module;

The short message service processing module is the core of the short message platform. It completes the business processing corresponding to various protocols, completes the message interaction according to the protocol flow, and converts the protocol of the short message sent to the target user, and guides the short message access module to complete the short message. Various operations of message business interaction;

The main function of the short message distribution module is to store and forward the short message. Since the short message uploaded by the user has been converted into the SMPP protocol format in the short message service processing module, there is no need to perform protocol conversion in the short message distribution module. Makes interconnection with other platforms easier.

At present, there are many protocols for fixed network short messages, such as the Chinese Terminal Service Interface CTSI (Chinese Terminal Service Interface) protocol, the European Telecommunications Standards Institute (ETSI) protocol for fixed network short messages (see ETSI ES 201912V1 for details .1.12002-01, of which there are two agreements). Each protocol defines a completely different data format in the data link layer and the message layer (or called the transport layer), resulting in a great difference in the implementation of the sending and receiving of short messages, and can only be done in mutually independent implemented on the platform.

At present, only a single protocol can be implemented on the fixed network short message platform, such as the CTSI protocol or ETSI and other fixed network short message protocols, and the short message communication between different protocol platforms can only be converted through the short message gateway. The short message platform can only access terminals that support the same protocol.

This independent implementation has the following disadvantages:

1) Since each platform can only implement a single protocol, terminal access is restricted.

2) Message interaction between terminals supporting different protocols can only be realized through the interconnection between platforms, and protocol conversion is inevitable, which increases costs for operators and wastes a lot of resources.

3) Operators cannot flexibly choose the type of protocol supported by the platform, which limits the services they provide.

According to the documents retrieved so far, no technical solution is found that can be compatible with multiple short message protocols on the same fixed network short message platform.

Fig. 1 and Fig. 2 are schematic diagrams of the process and platform structure of short messages in general fixed networks, which have been introduced in detail in the background technology and will not be repeated here.

Since the method of the present invention mainly involves the short message access module and the short message service processing module, the processing procedures of these two modules in the present invention will be described in detail below.

The processing flow of the short message access module in the short message uplink process is shown in FIG. 3 , and the details are as follows.

In step 1, users who support different protocols dial corresponding access numbers to access the short message platform, and the short message access module receives instructions from the short message service processing module;

Step 2, obtain the sending mode CIDtype and receiving mode ReceiveID corresponding to the protocol supported by the user terminal according to the message issued by the short message service processing module;

Step 3, send a message to the terminal, and the content of the message is determined by the short message service processing module according to the protocol supported by the terminal;

Step 4, the user terminal returns the message, and the short message access module uploads the message to the short message service processing module;

Step 5, if the uploaded message is a terminal release message, then end the information interaction;

Step 6, if the uploaded message is not a terminal release message, then receive the instruction of the short message service processing module, and judge whether the instruction is a platform release message instruction;

Step 7, if the instruction is not a platform release message instruction, go to step 2, otherwise end the information interaction.

The processing flow of the short message service processing module in the short message uplink process is shown in Figure 4, specifically as follows:

Step 1, after the user accesses the platform, the short message service processing module determines the protocol type ProtocolID supported by the user terminal according to the access number, and starts the corresponding service;

The 2nd step, send the instruction that has the sending mode CIDtype corresponding to the protocol type ProtocolID and the receiving mode ReceiveID to the short message access module;

The 3rd step, receive the short message uploaded by the short message access module, if the terminal releases the message, then go to the 8th step;

The 4th step, if the short message uploaded by the short message access module is not a terminal release message, then judge whether the short message is a short message that the terminal needs to send to the destination user, if not, then turn to the 6th step;

The 5th step, if yes, then user message is converted into the message of SMPP protocol data format, and upload short message distribution module;

The 6th step, obtains the next instruction issued by the short message service processing module according to the business logic, and judges whether it is a platform release instruction, if not, then turn to the second step;

Step 7, if the platform releases the command, then send the command with the sending mode CIDtype and the receiving mode ReceiveID to the short message access module, and the content of the command is to notify the user that the processing ends;

Step 8, the business processing ends.

The processing flow of the short message access module in the short message downlink process is shown in Figure 5, specifically as follows:

Step 1, receiving the instruction of the short message service processing module and calling the terminal;

The 2nd step, wait for the terminal to answer, if there is no answer, then report the short message service processing module, end the interactive process;

Step 3, after the terminal responds, obtain the sending mode CIDtype and receiving mode ReceiveID corresponding to the terminal support protocol according to the instruction of the short message service processing module;

Step 4, send a message to the terminal, wait until the user's message is received, and upload the user message to the short message service processing module;

Step 5, judge whether the user message is a terminal release message, if so, release the connection and end the information interaction;

Step 6, if the user message is not a terminal release message, then receive the instruction of the short message service processing module;

In the 7th step, if the instruction of the short message service processing module is not to release the message by the platform, then turn to the 3rd step;

Step 8, if the instruction of the short message service processing module is for the platform to release the message, then release the connection and end the interaction.

The processing flow of the short message service processing module in the short message downlink process is shown in Figure 6, specifically as follows:

Step 1, receiving the short message issued by the short message distribution module;

Step 2, according to the number of the destination user in the short message, query the user support protocol type ProtocolID;

In the 3rd step, the short message service processing module converts the SMPP message into the protocol data format corresponding to the protocol ProtocolID, and starts the corresponding service;

The 4th step, send the instruction that has the sending mode CIDtype corresponding to protocol ProtocolID and the receiving mode ReceiveID to the short message access module;

Step 5, receiving the message uploaded by the short message access module, and judging whether the uploaded message is an on-hook message applied by the terminal;

Step 6, if the upload message is a terminal hang-up message, then go to step 8; otherwise, obtain the next instruction issued by the short message service processing module;

The 7th step, judge whether this instruction is platform release instruction, if not, then go to step 4; Otherwise send the instruction with sending mode CIDtype and receiving mode ReceiveID to short message access module;

Step 8, the business processing ends.

Because the SMPP agreement is a kind of agreement that the interconnection between the short message platforms adopts most, so the short message platform of the present invention unifies the conversion of various protocol messages into the SMPP protocol type, which is convenient for the compatibility of various protocols and the interconnection between the platforms .
