Abstract

The invention provides a middleware system, which is used for providing services between a mobile equipment user and various content databases and is convenient for realizing an application program with a search function based on position on mobile equipment. The middleware system is used for providing one or more services for a user application program. For example, a service allows the user to note or mark a known semantics position. As another example, a service is used for providing a suggested semantics interesting point list for the user application program in response to user inquiry. The selection of suggested semantics interesting points is based on the position of the user and context-related information. The suggested semantics interesting points are possibly obtained from user personal information or in a similar form, suggested semantics positions are sequenced possibly, and the most interested semantics position of the user is in the first order.

Description

Location-based service middleware

Technical field

Middleware system provides the location-based service between mobile device user and the various content data base.

Background technology

The many different technology of integrated common employing that position-based service (LBS) is used, the radio network technique (for example Wi-Fi) and the global positioning system (GPS) that comprise mobile phone technology (as GSM), and other technologies, for example based on sensor network, radio-frequency (RF) identification (RFID) and similar product.Global positioning system provides the positional information on the geographical coordinate

But what the user was concerned about usually is the implication of a position, rather than its geographical coordinate, and it may be more significant use.For example, the name in hotel or dining room.Having fixing position, is by a title, rather than the place that geographical coordinate is determined is called semantic position.The position of a semanteme may be listed in the point of interest (POI) of a semanteme, generally is meant any product, service or fixing position are by a title, rather than geographical coordinate is determined the position.

Summary of the invention

The mobile device that has occurred new technology of many employings and standard in the past few years on the market, many mobile phones all have been equipped with web browser and have allowed the user to carry out many tasks, for example purchase goods, the inquiry of goods shipping situation, tour arrangement and reservation.Mobile device comprises any portable set that data processing and/or communication service capabilities are provided.For example, mobile device includes but not limited to, as cell phone, smart phone, beeper shows, radio frequency (RF) equipment, infrared (IR) portable devices equipment, PDA(Personal Digital Assistant), palmtop PC, notebook computer, panel computer, portable email equipment, on the one or more equipment that combine with integrated device, or the like.

Along with mobile device widely be connected, many interesting frontiers have occurred as general fit calculation (ubiquitous computing).This makes it can be provided in the line service, and in moving, no matter where the user is, can both provide to comprise such as a large amount of new services of the traditional services of accessed web page and Email.One class general fit calculation, be called " location-based service " (LBS), be more and more welcome, because their purpose provides the user " scene " information is provided, be that information belongs to a specific area users interest and can be in user's use, the position of visiting simultaneously in LBS.

Change a kind of saying, the location-based service service of can being defined as, integrated mobile device the position or with the position of other information so that offer user's surcharge.This service offers the location aware mobile device usually, and for example it can determine the GPS geographical position of oneself.A common inquiry, the background among the LBS that the user may cause are " to find nearest restaurant.Yet ", LBS can also provide more detailed information, particularly, and by the personal information data relevant of considering the user with other guide.

Description of drawings

Fig. 1 has shown the framework of a location-based service, and it adopts specific area ontological method.

Fig. 2 has shown one three layers communication pattern, can be used as the LBS (Fig. 1) that a framework is realized technically.

The middleware layer example that Fig. 3 shows provides the Additional Services that exceeded the traditional database inquiry service.

Embodiment

The framework of location-based service utilizes a middleware system, realizes every content search of user application and database, makes location-based application program on user's the mobile device use function of search based on body.Location-based service can offer the user of such mobile device effectively, and the geographical coordinate that can determine oneself uses global positioning system (GPS) or other.To service interface mobile device application program normally, be based on cloud computing (promptly using distributed computing platform) as mobile phone or an application program.Such application program makes the equipment user inquire about various databases, as a near restaurant finding, hotel, or the title semantic locations of the point of interest of other points (POI).Except the keyword of routine coupling, use search system in the inquiry that the user can carry out based on body, use as, the product type territory, search is sought in the COS territory in each territory.

In various example implementation, the selection of searching for semantic point of interest is based on user's position and possible contextual information, as morning and evening and date, current weather and traffic conditions.The selection of searching for semantic point of interest also may be based on user's customizing messages, as userspersonal information or similar.In some implementations the semanteme ordering that proposes of the application program of user that offers, the arrangement that the user may be most interested in is forward.

Another explanation middleware system provides the example of service, allows the mark of the known semantic locations of user comment.For example, a dining room is represented in the position of a semanteme, can come dining room of mark with photo or literal.As " great enchilada! " note or label may be related with user ID, as WindowsLive

ID.This note or label may or may not can offer other users.

The Application developer is creating the mobile device that numerous application program of user reside in the user, and many is the users that are used to provide with location-based service.For example, the on-site semantic point of interest of explicit user that service may be on map.Other application programs may relate to, and for example, follow the tracks of location-based selectivity diffuse information (as advertisement) and location-based recreation.Owing to relate to the database of integrating different-format, wherein comprise and with mobile service provider's network, the complexity of semantic interest point information geographical location information, middleware layer or system can be advantageously used in and reduce the integrated complexity of service.
