A method and system for information search through short message

technical field

The invention relates to mobile communication short message technology, in particular to a method and system for information search through short messages.

Background technique

At present, there are more than 400 SMS service providers (SPs) across the country, and each SP provides more than 4,000 types of services in 10 types of services, and each type of service contains a lot of different information. Therefore, "mobile The information on "Monternet" and "Unicom Zaixin" should be more than hundreds of thousands. Since the short message adopts a non-conversational communication method, a guiding component such as Portal cannot be provided, and the user must remember the service codes of various short message services. Due to the limited memory ability of people, generally only a few commonly used service codes can be remembered. For other services, they can only be queried through paper materials provided by operators or on the Internet, and there is a lack of direct service search or information search through SMS. Way.

At present, the network framework for providing short message value-added services is shown in Figure 1. The normal short message flow is as follows. When a user needs to query information or When customizing the service, you need to input the text message content according to the format specified by the SP, and then fill in the service code corresponding to the SP at the called number. After the SP receives the information submitted by the user through the Short Message Gateway (SMG), it will query the information according to the text message content. Then, the inquired information is replied to the user through a short message.

However, when users use the SMS value-added service of SP, they must first understand the service provided by a certain SP through the paper materials and advertisements provided by the operator or SP or inquire on the Internet, and then send the information according to the prescribed format. Query or service customization, but it is impossible to search for information by keywords for all services provided by SPs, so as to find SPs and SP services that meet user needs.

The technology of using computers to search information on the Internet has been very mature, but it is not possible to transplant the information search technology on the Internet to the short message system of the mobile network in combination with the characteristics of mobile phone short messages.

Contents of the invention

The invention provides a method for information search through short messages, so as to solve the problem in the prior art that users must know SP service codes and corresponding services in advance before using value-added services.

The present invention also provides a method for searching information through short messages, so as to solve the problem in the prior art that users cannot search for relevant information according to keywords through short messages.

In order to solve the above problems, the present invention provides the following technical solutions:

A method for searching information through short messages, comprising the following steps:

A. The user submits an information search request in the form of a short message through the terminal, and the information that the user wants to search is carried in the information search request as the content of the short message;

B, Short Message Center (SMSC) forwards this short message to Short Message Gateway (SMG) after receiving short message, by SMG this short message is routed to short message search engine;

C. The short message search engine searches for information according to the short message content in the information search request, and generates a short message according to the searched information and the user number in the information search request, and returns the short message to the user through SMG and SMSC.

In step A, the content of the short message is a keyword for searching information, and the number of the short message receiver is a dedicated service code.

In step B, the SMG routes the short messages to the short message search engine according to the dedicated service code, or routes all other short messages with incorrect service codes to the short message search engine.

The service information table of all service providers (SPs) is stored in the short message search engine, and the service information table includes service codes and corresponding service information.

After the short message search engine receives the information search request, it searches in the service information table according to the keyword, if there is information matching the keyword, then the information mode is returned to the user, if not, then the user is notified that there is no query to match information.

The short message search engine submits the keywords of the received information search request to the search engine website on the Internet for information search, and the search engine website on the Internet returns the search results to the short message search engine.

The short message search engine first performs information filtering, analysis, sorting and/or screening on the search results of the search engine website, and then returns the results to the user in the form of short messages.

According to different service codes, the short message search engine can distinguish whether to search for information in the service information table alone, in the Internet alone, or in the service information table and the Internet at the same time.

The terminal is a mobile terminal or a fixed terminal.

A kind of system that carries out information search by note, comprises user terminal, short message center (SMSC) and short message gateway (SMG) that provide short message service for user terminal; Wherein, this system also includes the short message search engine that is connected with SMG, this The short message search engine performs information query according to the information search request containing the content of the short message sent by the SMG. SMG and SMSC are returned to the user terminal.

The short message search engine is connected with the search engine website on the Internet through a private network or an IP metropolitan area network.

The user terminals include mobile and fixed terminals.

The present invention is connected with the short message search engine that stores the service information table of relevant SP at the SMG place, makes the user only need to input the keyword relevant with value-added service when the value-added service of mobile phone short message can search relevant service information, simultaneously, this The invention also provides information searching in the Internet through short messages. The invention greatly facilitates the mobile users to use the short message value-added service, and the potential of the short message service can also be further tapped.

Detailed ways

Aiming at the existing mobile short message technology, the present invention connects the short message search engine to the SMG in the mobile short message network, thereby solving the problem that the information search cannot be carried out through the short message in the prior art.

The system that carries out information search by short message that the present invention provides, comprises short message center (SMSC), short message gateway (SMG) and the short message search engine that is connected with SMG, and short message search engine is stored with the service information table that is used for information inquiry, and this The service information table contains the service codes and corresponding services of all service providers SP. Each SP service code and corresponding service introduction occupies one record, including at least two fields of SP service code and service introduction. The information search request sent by SMSC and SMG is used for information query.

The user's search for weather forecast information through SMS includes the following steps:

Step 10: The user sends a short message to submit an information search request through a mobile station (MS) or a fixed phone (with short message sending and receiving function). The content of the short message is to input "weather forecast" as a keyword. Special business code for information search via SMS;

Step 20: after the short message center (SMSC) receives the short message, forward the short message to the short message gateway (SMG) according to the service code, and the short message is routed to the short message search engine by the SMG;

In order to save the user from memorizing the special service code, SMG not only routes the short message to the short message search engine according to the special business code, but also routes all other short messages with incorrect business codes to the short message search engine, so that the service code entered by the user is incorrect. If you have a dedicated service code or a service code other than that of another SP, you can also enjoy the service of information search by SMS.

Step 30: The SMS search engine searches the service information table according to keywords, such as "weather forecast", and if there is information matching the keyword, generates a SMS according to the information and the user number in the information search request , if no matching information is found, a notification message will be generated.

If there is a lot of information matching the keyword "weather forecast", it can be divided into multiple text messages to reply to the user. In order to avoid the inconvenience caused to the user by replying too many text messages, for non-ending text messages, it can be appended to the end of the text message content To obtain the instructions for the next piece of information, for example, the user can be prompted: "There are N pieces of relevant information this time, and the next piece of relevant information can be obtained by directly replying to a text message", and the user can decide on his own according to his needs.

Step 40: The short message search engine sends the generated short message to the MS via SMG and SMSC.

In order to obtain more information, the SMS search engine can be connected to the search engine website on the Internet through a private network or IP MAN. There is no uniform standard for the interface protocol, and it needs to be negotiated with the Internet search engine. XML or HTTP protocol can be used , when the SMS search engine judges that the message is a search request on the Internet according to the service code in the short message forwarded by SMG, fill in the protocol document in XML/HTTP format according to the agreement agreed with a certain search site in advance, which includes There are keywords to be searched and sent to the website. The website searches according to the keywords and sends the results back to the SMS search engine. The SMS search engine can filter, analyze, organize and/or search the search results of the search engine website or filter. The search result may be multiple messages, each of which may have a lot of content. The first reply message is the first 55 Chinese characters or 110 Western characters of the first search message, and the end prompts the user to "Reply 0 to continue, Reply 1 for the next article" wait. When the user replies 0, the SMS search engine will reply the user with the last 55 Chinese characters or 110 Western characters of the first search information; when the user replies 1, the SMS search engine will reply the first 55 Chinese characters or 110 Western characters of the second search information Reply to the user with text; there are hints at the end. If the user does not reply, stop sending subsequent search results and discard the search results.

The present invention also provides that the short message search engine can distinguish information searches in the business information table alone, in the Internet alone or in the business information table and the Internet at the same time according to different business codes, and users can selectively search for information according to their own needs. search.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. In this way, if the modifications and variations to the present invention fall within the scope of the claims of the present invention and equivalent technologies, these modifications and variations should also be included in the scope of the claims of the present invention.
