Detailed Description

According to one or more embodiments, as shown in fig. 1, a SMS message system includes a system initialization module, a wetui module, an OAMD module (OAM-midwall, which is an intermediate layer module and is a communication bridge between WEBUI and a bottom layer), an SMS message module, and an lte module.

And the system initialization module runs a system initialization script, starts an LTED process when the equipment is started, also comprises related initialization of SMS and performs related early-stage setting for short message service.

And the SMS module is used for setting a short message center number, a short message storage position and the like after being started, and starting a response thread and a real-time state reporting thread of a user interface of the WEBUI module.

The LTE module (LTE, which is a long term evolution of 3GPP technical standard, and is responsible for network-related operations) performs network access and IP acquisition, and performs data communication with the SMS short message module.

The WEBUI module is a WEB user interface and issues some requests to the SMS short message module, and the requests mainly comprise sending, deleting, reading, short messages, refreshing a short message list and obtaining or configuring a short message center number.

And the OAMD module provides related interfaces of SMS configuration, is used by the SMS short message module and a WEB User Interface (UI), and transmits the content of the short message and issues the instruction request.

After the equipment is started, the equipment starts a system starting script, and an LTED module is started in the script. At this time, in the process of reinitializing the LTED module, the SMS module, namely the short message function, is started. And sending an AT command related to the short message to initialize the short message function.

As shown in fig. 2, the SMS message module is started in the lte process, which is initiated by initializing the SMS and other functions of the module such as accessing the network, creating two threads, responding to the threads of the page request (including SMS message request, sending, deleting, reading, etc.) and the real-time state thread (obtaining a message list in real time), sending the corresponding AT command to the communication module after the LTED receives the related request, and taking out the result returned by the module, and writing the result into the corresponding nv node (here, the nv node is a memory node, which is a space opened in software for storing data, facilitating indirect communication between the processes by reading data content) or a corresponding file for obtaining a web page.

As shown in fig. 3, the WEB request of the WEBUI module mainly includes sending and reading a short message, and initializing a short message format to be a PDU short message, so when sending a short message, characters that need to convert the content of the short message input on a page into the PDU format are sent to the module for sending, and due to the limitation of length, the short message is split and sent after exceeding a certain length, thereby supporting the sending of long short messages. The received short message content is also a character string in a PDU format, the character string in the PDU format is converted into corresponding English or Chinese characters to be displayed when a page reads or refreshes a short message list, a deleting request is that a short message to be deleted is selected in the page, and the webpage transmits the index of the short message to an LTED (SMS) module to delete the short message according to a command.

After the device main process is started, a command for listing all short messages is continuously sent, the obtained result is compared with the previous short message every time, and if the short message is updated (a new short message is received or the short message is deleted), the new short message is written into the text to create a short message list.

The WEBUI module mainly comprises an inbox, an outbox and a setting interface, wherein the setting interface is mainly used for configuring a number of a short message center, the number of the short message center is generally obtained from an SIM card through a command when the mobile terminal is started and initialized in an LTED (SMS) module, if the number of the short message center is not obtained in the SIM card, the number of the short message center is set through a page according to a short message center of a related operator, and the inbox and the outbox display read, unread, sent and unsent messages according to related identifiers.

The implementation of the PDU message is described in detail below.

The sending of short messages is usually in Text and PDU (Protocol Data Unit) mode. The Text mode is simple to use for receiving and sending short message codes, and is very easy to realize, but the biggest defect is that the Chinese short message cannot be received and sent; the PDU mode not only supports Chinese short messages, but also can send English short messages. The PDU mode may use 3 kinds of codes for sending and receiving short messages: 7-bit, 8-bit and UCS 2. 7-bit encoding is used to transmit plain ASCII characters, which encodes a string of 7-bit characters (highest bit 0) into 8-bit data, each 8 characters being "compressible" into 7; 8-bit encoding is commonly used to send data messages such as pictures and ring tones; and the UCS2 encoding is used to transmit Unicode characters. Under the three encoding modes, the maximum capacity of the user information (TP-UD) section (the maximum number of characters of the short message which can be transmitted) of the PDU string is 160, 140 and 70 respectively. Here, one english alphabet, one chinese character, and one data byte are all regarded as one character.

The user information length (TP-UDL) of a PDU string has different meanings in various encoding modes. When 7-bit is coded, the number of characters of the original short message is referred to, but the number of bytes after coding is not referred to. When 8-bit is coded, the number of bytes is just. UCS2 encodes it, also in number of bytes, equal to twice the number of characters of the original short message. If a header (basic parameter TP-UDHI is 1) exists in the user information (TP-UD), the length (TP-UDL) of the user information is equal to the sum of the length of the header and the number of bytes after encoding under all encoding modes. If the compression algorithm proposed by GSM 03.42 is used (001 for the upper 3 bits of the TP-DCS), the length is also the compressed encoded byte number or the sum of the header length and the compressed encoded byte number.

Currently, Text and pdu (protocol Data unit) modes are commonly used for sending short messages. The Text mode is simple to use for receiving and sending short message codes, and is very easy to realize, but the biggest defect is that the Chinese short message cannot be received and sent; the PDU mode not only supports Chinese short messages, but also can send English short messages. The PDU mode may use 3 kinds of codes for sending and receiving short messages: 7-bit, 8-bit and UCS 2. The 7-bit encoding is used to transmit plain ASCII characters, the 8-bit encoding is typically used to transmit data messages, and the UCS2 encoding is used to transmit Unicode characters. The general PDU code consists of thirteen items A B C D E F G H I J K L M.

A: short message center address length, 2-bit hexadecimal number (1 byte).

B: type of short message center number, 2-digit hexadecimal number.

C: the short message center number, B + C, will be determined by the data in a.

D: pduType, 2-bit hexadecimal number.

E: message Reference, 2-bit hexadecimal number.

F: called number length, 2-bit hexadecimal number.

G: the type of the called number, 2-bit hexadecimal number, takes the same value as B.

H: the called number, length is determined by the data in F.

I: protocol identification, 2-bit hexadecimal number.

J: data encoding scheme, 2-bit hexadecimal number.

K: validity period, 2-bit hexadecimal number.

L: user data length, 2-bit hexadecimal number.

M: user data, the length of which is determined by the data in L. The J is encoded by UCS2, and here is a Unicode character in chinese and english.

The encoding and decoding of the PDU includes:

(1) english coding and decoding

The default GSM character set is 7-bit encoding, the ASCII code is 8-bit encoding, and the encoding is to convert 8-bit ASCII encoding into 7-bit encoding. For example: 1234 encoded to give 31D98C 06. After "1234" is represented by binary, the code is converted to 7-bit code as follows:

8 bit code 00110001001100100011001100110100

7 bit code 00110001110110011000110000000110

By way of example, it can be seen that Bit8 of ascii8 Bit code is removed, and the next few bits of the next 7 Bit code are successively shifted to the front to form a new 8 Bit code. Decoding is the reverse process of the above, namely converting a 7-bit character code into an 8-bit character code.

(2) Chinese coding and decoding

The Chinese coding is simple, namely the Chinese coding of GB2312 is converted into the Unicode coding. Decoding is just to convert the Unicode code into the Chinese code of GB 2312.

In daily short message receiving and sending, Chinese short messages are more, English short messages can also be received and sent as Chinese short messages, and if the program requirement is not high, all short messages can use Chinese codes.

The function realized by the embodiment of the invention can lead the router to send and receive the short message in a webpage form, and not only just like the conventional router only supports the network access function. The technical means involved in the middle are the problems of inter-process communication (message queue), short message coding mode, AT configuration mode, memory storage and the like.
