Detailed ways

Sending faxes by using mobile phone short messages is a unique service. It is a value-added service for fax communications based on mobile networks. It provides fax sending services for enterprises and individuals with the help of the backbone telecommunications network channels of operators. After the mobile phone subscribes to this service, it can send a short message to a specific number, and the server will convert the short message into a fax, and send the fax through the public switched telephone network (PSTN).

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

The invention provides a method for sending and receiving faxes by a mobile phone, which is used for sending a fixed-line fax by a user's mobile phone through a short message, including:

Step 1, the user edits the short message on the mobile phone, sends the fax content and the fixed-line fax number for receiving the fax to a specific short message access code, and the short message center forwards the short message to short message gateway;

Step 2, the short message gateway searches for the corresponding fax server according to the specific short message access code, and forwards the short message to the fax server, and the fax server processes the short message according to the standard format, according to Submit The ChargeNumber field in the command extracts the mobile phone number sending the fax, the fixed-line fax number and the fax content of the receiving fax, then converts it into a TIF tag image file format (Tagged Image File Format, abbreviated as TIFF) file, and sends it to the voice switch;

Step 3, the voice switch sends the fax content to the fax machine corresponding to the fixed-line fax number of the received fax through the PSTN according to the fixed-line fax number of the received fax.

Also includes:

Step 41, after the fax content has been sent, the fax server sends a short message to notify the short message gateway that the fax content has been sent;

Step 42, the short message gateway sends a short message to notify the short message center that the fax has been sent;

Step 43, the short message center sends a short message to notify the user that the fax content has been sent.

Before step 1, the user's mobile phone also sends a short message to the specific short message access code to request to activate the service of sending fixed-line faxes through short messages.

The standard format is T.38 format, and the short message gateway supports Short Message Gateway Interconnection Protocol (SGIP) and China Mobile Internet Short Message Gateway Interface Protocol (CMMP).

The following describes in detail the flow of sending a fax by a mobile phone short message provided by the present invention with reference to the accompanying drawings. The user sends a specific instruction (such as CZ) to a specific short message access code, and the mobile communication system activates the fax service for the user. After the user subscribes to the fax service, the process of sending a fixed-line fax via a short message is shown in Figure 1. The user edits the content of the short message on the mobile phone "#Receiving Fax's Fixed-line Fax Number#Fax Content" and sends it to a specific short message access code The short message center forwards the short message to the short message gateway according to the specific short message access code, and the specific internal process is as follows:

(1) Edit the fixed-line fax number and fax content for receiving faxes on the mobile phone, enter a specific short message access code, and send a short message to the Short Message Center (SMSC);

(2) SMSC sends SMPP (short message point-to-point) command SUBMIT_SM request to the SGIP short message gateway connected with SMSC according to network routing after receiving the short message sent by user's mobile phone;

(3) After the SGIP gateway receives the request from the SMSC, it searches for the fax server corresponding to the SP according to the SP access number (that is, the specific short message access code) and the command code in the request.

(4) The SGIP short message gateway sends the fax request and content to the fax server, and the fax server replies to the SGIP short message gateway;

(5) The fax server processes the fax content according to the T.38 format and sends it to the voice switch;

(6) The voice switch sends the fax content to the PSTN network;

(7) The ordinary facsimile machine rings, picks up the hook, establishes a T.38 session connection with the fax server, and the ordinary facsimile machine receives the fax content;

(8) The fax server sends a short message to notify the SGIP short message gateway that the fax has been sent, and the SGIP gateway replies;

(9) The SGIP short message gateway sends a short message to notify the SMSC that the fax has been sent;

(10) The SMSC sends a short message to the user's mobile phone, notifying that the fax has been sent.

The present invention can also support the transmission of fax content exceeding 70 Chinese characters. For the fax content of more than 70 Chinese characters: (1) If the mobile phone supports long and short messages, you can enter more than 70 Chinese characters in a short message, and add a special identifier at the end of the short message, such as "#", the mobile phone will divide the short message and send it to After the fax server, the fax server extracts the content according to the TP_udhi field value and time order in the Submit command until "#" is extracted, and then merges the content of the short messages divided by the mobile phone; (2) If the mobile phone does not support long and short messages, a Only 70 Chinese characters can be entered in the text message, then the user will divide the fax content into multiple short messages and add a special identifier, such as "#", at the end of the last short message. After sending to the fax server, the fax server will Extract the content until "#" is extracted, and then merge the content. If the fax content does not exceed 70 Chinese characters, add a special identifier, such as "#", at the end of the short message. After sending to the fax server, the fax server will extract "#", and process the fax content according to the T.38 format.

The present invention provides a network fax sending and receiving system, as shown in Figure 2, used for mobile phone users to send fixed-line faxes through short messages, including user mobile phones, mobile cellular networks, short message gateways, voice switches, PSTN, fax machines, Among them, PSTN uses 2M dedicated line access (digital No. 7 signaling), and can make local calls, domestic and international long distance calls. The mobile cellular network is responsible for sending and receiving short message access for users within the network. It also includes a fax server and a short message center. The fax server is responsible for connecting to the digital voice relay for sending and receiving faxes.

The fax server is respectively connected with the short message gateway and the voice switch, and is used to receive the fax content and the fixed-line fax number of the fax, and send it to the voice switch after processing according to the standard format; The message notifies the short message gateway that the fax content has been sent;

The voice switch is used to send the fax content to the fax machine corresponding to the fixed-line fax number for receiving the fax through the public switched telephone network according to the fixed-line fax number for receiving the fax;

The mobile phone of the user is also used to send the fax content and the fixed-line fax number for receiving the fax to a specific short message access code; it is also used to send a short message to the specific short message access code to request to open the fixed-line fax through the short message Business;

The short message center forwards the short message to the short message gateway according to the specific short message access code; it is also used to send a short message to notify the user that the fax content has been sent;

The short message gateway is used to search the corresponding fax server according to the specific short message access code, and forward the short message to the fax server; it is also used to send a short message to notify the short message center that the fax content has been sent; The short message gateway mentioned above supports SGIP and/or CMMP.

The user's mobile phone is also used to input a special mark at the end of the short message content, indicating that the short message content has been input;

The fax server is also used to merge two or more short messages according to the special mark at the end of the short message content.

The standard format is T.38 format.
