Description

Point-to-multipoint group sending method of terminal short message

Technical field

The invention relates to group sending of short messages in mobile and fixed communication networks.

Background technique

In the existing communication systems, including GSM, CDMS and 3G and fixed communication systems, the short message group sending function of mobile phones and other terminals is widely used in: the contact between the company and many employees who are on business trips, the company releases new product information to users, Send greetings, congratulations, etc., release the account fund usage and balance status to individual bank card users, send payment receipt information to industrial and commercial enterprises, etc., the transportation system releases information to car owners and drivers, etc., the securities industry releases specific information to shareholders, etc., shopping malls , The supermarket releases news about commodity discounts, deals, etc. to customers, and so on.

There are many ways to realize the short message group sending function, and the following two are more common at present.

1. The original technology realizes the terminal short message group sending mechanism 1

As shown in Figure 2, the basic idea of this mechanism is: after the end user writes the short message, he needs to input the number of the target user multiple times and send it multiple times.

2. The original technology realizes the terminal short message mass sending mechanism 2

The other is the method of terminal + computer, as shown in Figure 3. The difference between it and the previous mechanism is that after the user writes a short message, he enters the numbers of multiple target users at a time, and the computer completes the multiple sending of the short message .

Contents of Invention

There is following shortcoming in above-mentioned prior art:

1. The operation of the original solution 1 is complicated, and the user needs to input the target user numbers one by one and send them one by one.

2. Although the original scheme two simplifies the operation, it needs to be used in conjunction with a computer and special software.

3. Although the forms of the two original schemes are different, their essence is the same: the information of the same content must be sent multiple times on the air interface part and the line, wasting increasingly tense radio frequency resources and voice channel resources.

Compared with above-mentioned best prior art, the present invention has following advantage:

Using the technology of the present invention, the user can conveniently realize the group sending function of the short message through the terminal, which is easy to operate and has a high degree of integration. It saves the precious wireless spectrum resources of operators, improves the spectrum utilization rate, and can be applied to the relevant standards of the next generation wireless communication system (4G). But there are also disadvantages at the same time, for example, higher requirements are placed on the terminal and the short message center (SMC), and some new short message distribution function processes need to be added to the SMC.

According to the ideas of the point-to-multipoint group sending method of terminal short message, the following two methods of point-to-multipoint group sending of terminal short message are designed.

Terminal short message point-to-multipoint group sending method 1:

SMC or ICP needs to make a business process. When a user sends a short message to a group, the sending terminal only needs to send it once on the physical layer. The specific steps of the process are as follows:

1) The user customizes one or more group numbers to the ICP or SMC through a computer or wireless terminal;

2) ICP or SMC accepts this group information and stores it in the relevant database, and replies to the user with a successful customization message;

3) The user sends the SMS to the SMC with the group as the destination address (DA), and the SMC sends a request to the DB to get the group number, and the database (DB) returns each number of the designated group to the SMC;

4) The SMC re-encapsulates the SMS with each number of the returned group as the DA, uses the extended distribution process, sends the SMS to each terminal with standard SMS signaling, and returns the sending success message to the user.

Operators can provide users with preferential billing schemes according to the size of the defined group. Its advantage is that it does not need to change the short message process of the terminal, and its disadvantage is that it is not flexible enough. This method is suitable for SMS sending in large groups.

Method 2 for terminal short message point-to-multipoint group sending:

SMC needs to make a business process, and at the same time, the SMS format needs to be expanded. When sending a short message to a group, the sending terminal only needs to send it once on the physical layer. The specific steps of the process are as follows:

1) The SMS format of the interface between the terminal, the switch and the short message center is expanded;

2) The user sends the SMS to the SMC with the multi-terminal number as the DA by using the extended short message signaling interface;

3) After the SMC receives the short message with multiple destination numbers sent by the user, it re-packages the SMS with each terminal number as DA, sends the SMS to each terminal with standard SMS signaling, and returns the sending success message to the user .

The user does not need to customize, and the flexibility is strong. The disadvantage is that the SMS format needs to be expanded, and the short message flow of the terminal and SMSC needs to be modified, which has a great impact on the existing system and terminal. This method is suitable for sending SMS in small groups.

Detailed ways

One embodiment of the terminal short message point-to-multipoint group sending method:

SMC or ICP makes a special business process, such as: the user customizes one or more group numbers online on the ISP (SMC) or through the terminal in the form of short messages (corresponding to the user's MSISDN, and can only be used by the user) ), and send to the ISP or SMC. Each group corresponds to a series of phone numbers (including mobile phone numbers and fixed phone numbers), and the group information is stored in the relevant database. After that, users can send short messages to this group at any time, and complete the short message through the server of ISP or SMC. distribution. Operators can provide users with preferential billing schemes according to the size of the defined group. Its advantage is that it does not need to change the short message process of the terminal, and its disadvantage is that it is not flexible enough. This method is suitable for SMS sending in large groups.

Basic process:

1. Customized groups As shown in Figure 5 and Figure 6, SMC or ICP adds a new process to accept users to customize groups online through computers or wireless terminals, and store the group information.

2. SMS Sending Interface 1 and Interface 2 in Figure 4 use standard short message signaling, and the sending terminal sends the short message whose target address is the group number to the short message center.

3. SMC completes the distribution of SMS As shown in Figure 7, after receiving the group number sent by the user, the short message center uses the extended distribution process according to the target number specified by the user's group information, through interface 3 in Figure 4, Use standard short message signaling to complete the distribution of short messages to each target number.

Embodiment 2 of the terminal short message point-to-multipoint group sending method:

The short message center has a special business process, and the SMS format needs to be expanded, and the user can directly send a short message to multiple (less than or equal to 6) phone numbers through the terminal at one time. The user does not need to customize, and the flexibility is strong. The disadvantage is that the SMS format needs to be expanded, and the short message flow of the terminal and SMSC needs to be modified, which has a great impact on the existing system and terminal. This method is suitable for sending SMS in small groups.

Basic process (see Figure 9):

1. Interfaces 1 and 2 in FIG. 8 use the extended short message interface signaling, and the sending terminal sends short messages containing multiple destination addresses to the short message center at one time.

2. After receiving the short message with multiple destination numbers sent by the user, the short message center uses the extended distribution process and standard short message interface signaling to complete the distribution of the short message to each number terminal through interface 3.

3. The sending terminal, switch (gateway), and short message center need to support extended short message interface signaling. Short message interface signaling extension method

The SMS-SUBMIT types for basic SMS are: abbreviation refer to P1) P2) describe TP-MTI TP-message-type-indicator m 2b Parameters describing the message type TP-RD TP-nonconforming product-replica m b ... TP-VPF TP-validity-period-format m 2b parameter indicating whether the TP-VP field is current TP-RP tp-reply-path m b parameter indicating the path of the request reply TP-UDHI tp-user-data-topic-indicator o b parameter indicating that the TP-UD field contains a topic TP-SRR tp-status-report-request o b Parameter indicating whether the MS requests a status report TP-MR TP-Message-Reference m I Identify parameters of SMS-SUBMIT TP-DA TP-target-address m 2-12o The address of the target SME TP-PID TP-Protocol-Identifier m o Identify the parameters of the upper layer protocol (if any) TP-DCS TP-Data-Coding-Design m o Coding Design in Parameter Identification TP User Data abbreviation refer to P1) P2) describe TP-VP TP-effectiveness-period o o/7o parameter identifying the time since the message was no longer valid TP-UDL TP-User-Data-Length m I parameter indicates the length of TP user data to the next field TP-UD TP-User-Data o 3)

The short message interface signaling extension method is to use the reserved bits of TP-PID to extend TP-DA, and the specific method is as follows:

Bit7 and bit6 of TP-PID are 00, 01, and 11 have been used, while 10 is reserved for unused. In this extension method, 10 is used for bit7 and bit6, and bit5, bit4, and bit3 of TP-PID are used to indicate the number of target terminals. The length of the TP-DA field is represented by bit5bit4bit3 of TP-PID, which is extended from 2-12 bytes (bit5, bit4, bit3: 001, corresponding to a terminal number) to a maximum of 72 bytes (bit5, bit4, bit3: 110 , corresponding to 6 terminal numbers). In this way, the terminal user can send a short message containing up to 6 target addresses to the SMC at one time, and the SMC completes the distribution of the SMS.

Those skilled in the art should be well aware that the method for point-to-multipoint group sending of terminal short messages of the present invention is not only applicable to the text short message SMS mentioned above, but also applicable to multimedia short message MMS and enhanced short message EMS.
