Description

Method and system for realizing restricted forwarding of short messages

technical field

The invention relates to the technical field of mobile communication, in particular to a method and device for realizing restricted forwarding of short messages.

Background technique

In modern society, mobile phones, that is, mobile phones, have become an indispensable communication tool for people. In daily life, SMS (Short Message Service: Short Message Service) has been generally accepted and widely used by the majority of mobile phone consumers because of its convenience, quickness and cheapness.

SMS is a store-and-forward non-real-time message service, and its sending and receiving are divided into the following five steps:

A. The sender sends a message (SMS-SUBMIT)

The message sender sends SMS-SUBMIT message to SMSC (Short Message Service Center: short message service center).

B. SMSC notification sender (SMS-SUBMIT-REPORT)

The SMSC sends an SMS-SUBMIT-REPORT message to notify the sender of the message.

C. SMSC sends a message (SMS-DELIVER)

SMSC sends SMS-DELIVER message to message receiver.

D. Receiver notifies SMSC (SMS-DELIVER-REPORT)

The message receiver sends an SMS-DELIVER-REPORT message to notify the SMSC.

E. The SMSC informs the sender that it has been sent (SMS-STATUS-REPORT).

Today, SMS is not only a business, a means of communication, but also a popular thumb culture in modern daily life. Sending short messages has become an indispensable contact method in many people's lives. Some short messages with popular content are often forwarded among many mobile phone users. Many short messages are purchased by network promoters from the authors of the short messages, while network promoters can only buy them from local downloaders directly from network promoters. Get paid. And sometimes the author of short message is also unwilling that the short message edited by it is forwarded without restriction.

In this way, certain losses have been brought to the author or the network promoter of this short message. How to solve this problem by limiting the forwarding of the short message has been an urgent demand of many network promoters and short message authors.

Detailed ways

The implementation method of a kind of short message restriction forwarding of the present invention, its specific implementation as shown in Figure 1 sender realizes the concrete process of restriction forwarding short message as:

Step 11, the user prepares to send a short message;

The short message to be sent here can be edited by the user himself, or it can be a short message to be forwarded without forwarding restrictions.

Step 12, judging whether the short message restriction forwarding function needs to be set, if so, execute step 13, otherwise execute step 14;

Step 13, according to the setting of the short message restriction forwarding function of the system, add the short message restriction forwarding information for the short message;

Of course, there are three types of short message restriction forwarding information in this step:

1. There is no need to restrict the forwarding of sent short messages;

2. Limit the number of short message forwarding times sent;

3. It is not allowed to forward the sent short message;

According to the specific content of the short message sent, the user can set the type of adding short message restriction forwarding information to the short message;

Step 14, sending a short message.

The above process only completes the setting of SMS restricted forwarding at the sending end. If the function of SMS restricted forwarding is fully implemented, the following process must be completed at the receiving end:

As shown in Figure 2, the specific process after the receiving end receives the above-mentioned short message is:

Step 21, the receiving end needs to forward the short message;

Step 22, obtaining the short message restriction forwarding information in the short message;

Step 23, judging whether there is short message restriction forwarding information, if it is to execute step 24, otherwise execute step 28;

Step 24, judging the type of the short message restriction forwarding information,

If it is to limit the number of forwarding times of the short message sent, perform step 25;

If it is not necessary to limit the forwarding of the sent short message, perform step 28;

If it is not allowed to forward the sent short message, perform step 29;

Step 25, judging whether the number of times to limit short message forwarding is greater than 0; if so, perform step 26, otherwise, perform step 29

Step 26, decrementing the limited number of short message forwarding times in the short message limited forwarding information by 1; and saving it as new short message limited forwarding information;

Step 27: Set short message restriction forwarding information in the forwarded short message that does not allow the forwarded short message to be forwarded.

Step 28, forwarding the short message;

Step 29, refuse to forward the short message, and return to the standby state.

In the above short message sending process, in order to implement or cancel the short message restricted forwarding function, whether to enable the short message restricted forwarding function can be set at the sending end and/or the receiving end.

The short message restriction forwarding system that realizes said method of the present invention, as shown in Figure 3, comprises: the sending device of short message restriction forwarding and the receiving device of short message restriction forwarding, wherein:

Sending device for limiting forwarding of short messages: located at the sending end of short messages, including: a setting module for limiting forwarding of short messages, a user interface module for short messages and a functional module for sending short messages, wherein:

Short message restriction forwarding setting module: used to increase the short message restriction forwarding setting item in the short message, and set the type of the short message restriction forwarding information; the type of the short message restriction forwarding information includes: no need to restrict the forwarding of the sent short message , Limiting the number of forwarding times of the sent short message and not allowing the forwarding of the sent short message.

Short message user interface module: block connection short message limit forwarding setting module, to realize the setting and viewing of short message limit forwarding information in the short message limit forwarding setting module by the user;

Short message sending function module: connect the short message limit forwarding setting module and the short message user interface module, and send the short message configured with the short message limit forwarding information to the SMSC.

Receiving device for restricted forwarding of short messages: located at the receiving end of short messages, including a short message receiving function module, a short message user interface module and a short message forwarding module, wherein:

Short message receiving function module: receive short messages sent by SMSC that have been configured with short message restriction forwarding information;

Short message user interface module: connected to the short message receiving function module, to realize the user's viewing and confirmation of the short message restriction forwarding information in the short message setting module;

Short message forwarding module: connected with the short message user interface module and the short message receiving function module, forwarding the short message to SMSC according to the user's confirmation.

The above-mentioned short message user interface module is shared by the sending device with restricted forwarding of short messages and the receiving device with restricted forwarding of short messages, and is an original short message user interface module.

The above-mentioned short message restriction forwarding setting module is a submodule added in the short message setting module of the original sender;

The above-mentioned short message sending function module is a submodule added in the short message function module of the original sending end;

The above-mentioned short message receiving function module is a submodule added in the short message function module of the original receiving end;

The above-mentioned short message forwarding module is a submodule added to the short message function module of the original receiving end.

The above-mentioned implementation mode is combined with a specific mobile terminal, and its scheme is as follows:

First, add the definition of the information element identification in the TP-UD field Header in the 3GPP TS 23.040 V3.9.0 protocol: as shown in Table 1

Table 1

hexadecimal value meaning 00 Concatenated short messages, 8-bit reference number 01 Special SMS Message Indication 02 Reserved 03 Value not used to avoid misinterpretation as<LF>character 04 Application port addressing scheme, 8 bit address 05 Application port addressing scheme, 16 bit address 06   SMSC Control Parameters 07 UDH Source Indicator 08 Concatenated short message, 16-bit reference number 09 Wireless Control Message Protocol 0A Text Formatting 0B Predefined Sound 0C User Defined Sound(iMelody max 128 bytes) 0D Predefined Animation 0E Large Animation(16*16 times 4＝32*4＝128 bytes) 0F Small Animation(8*8 times 4＝8*4＝32 bytes)

10 Large Picture (32*32＝128 bytes) 11 Small Picture (16*16＝32 bytes) 12 Variable Picture 13-1F Reserved for future EMS features(see clause 3.10) 20   RFC 822 E-Mail Header 21-6F Reserved for future use 70-7F (U)SIM Toolkit Security Headers 80-9F SME to SME specific use A0-BF Reserved for future use C0-DF SC specific use E0-FF Reserved for future use

Secondly, in order to realize the limited forwarding function of short messages, the message element identification in the 3GPP TS 23.040 V3.9.0 protocol is extended. The short message sender is required to add a short message restriction forwarding information element (Information EIement) in the TP-UD field Header field of the SMS-SUBMIT message.

This information element includes the following three parts:

1) Information element identification:

It can be seen from the above definition that 02, 21-6F, A0-BF, and E0-FF are all reserved values, that is, they are not applied in the existing short message implementation. Therefore, it may be considered to randomly select a value from these reserved values as the identifier of the short message restricted forwarding information element.

The sender of the short message adds the short message restriction forwarding information in the SMS-SUBMIT message through the identifier, and the short message receiver obtains the short message restriction forwarding information from the SMS-DELIVER message through the identifier.

2) Information element size:

Set to 2, i.e. two octets, i.e. the subsequent data field contains two octets.

3) Information element data:

First octet:

0: FORWARD-ALLOWED, allowing the recipient of the short message to forward the short message;

1: FORWARD-LIMITED, limit the short message receiver to forward the short message;

Second octet:

An unsigned number between 0-255, the mark limits the number of forwarding times. When the number is 0, the recipient of the short message is prohibited from forwarding the short message. That is, when the short message sender enables the limited forwarding function of the short message, the short message created and sent by the short message sender can be forwarded 255 times by the short message receiver in the network at most.

The short message receiver needs to be able to obtain the short message forwarding information element of the short message sender, and requires the SMS-DELIVER message sent by the SMSC to the short message receiver to include the same short message forwarding information element in the SMS-SUBMIT message.

Furthermore, set the short message restriction forwarding user interface at the protocol layer

1) Short message limit forwarding setting interface

This interface is used for the short message sender to add corresponding short message restriction forwarding information elements in the SMS-SUBMIT message when sending the SMS-SUBMIT message. This information element identifies whether the short message sender allows the short message receiver to forward the short message and the maximum number of times the short message can be forwarded in the network.

2) Short message limit forwarding access interface

This interface is used for the short message receiver to extract the corresponding short message restriction forwarding information element from the SMS-DELIVER message when receiving the SMS-DELIVER message. This information element identifies whether the short message sender allows the short message receiver to forward the short message and the maximum number of times the short message can be forwarded in the network. When there is no corresponding short message forwarding restriction information element in the SMS-DELIVER message, it is considered that the short message has no forwarding restriction set by default.

The above-mentioned implementation scheme is mainly to realize the limited forwarding function of short messages through the expansion of the existing 3GPP related SMS protocols and the cooperation of upper-layer SMS-related applications. Of course, the limited forwarding function of short messages can also be realized through the following schemes:

1. When the sender of the short message sends the SMS-SUBMIT message, he can insert a special identifier in the specific position of the short message text data segment in the TP-UD field to identify whether the short message receiver is allowed to forward the short message and can forward it. times information.

2 After receiving the SMS-DELIVER message, the short message receiver reads the special identifier at the corresponding position of the short message text data segment in the TP-UD field, and the identifier identifies whether the short message receiver is allowed to forward the short message And information about the number of times that can be forwarded.

3 The specific implementation process is similar to the process described above, the difference is that the short message restriction forwarding information here is passed between the short message sender and the receiver through the short message text data area in the TP-UD field of the SMS-DELIVER message Delivered instead of via the SMS Restricted Forwarding Information element in the TP-UD field Header of the SMS-DELIVER message.

This scheme does not need to expand the existing SMS protocol, and its implementation is relatively simple, but it requires both the sender and receiver of the short message to reach a consensus on the special identifier. However, it is an urgent task to reach this consensus among different terminal providers. Its difficult thing, therefore limits the versatility of this short message restriction forwarding function among various short message terminal users.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present invention can easily think of changes or Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
