Description

Method and device for correcting the positioning of a mobile terminal

technical field

The present invention relates to the technical field of network information, and more specifically, relates to correcting the position of a mobile terminal.

Background technique

With the popularization of mobile terminals, the types of services applied to mobile terminals continue to expand, and the communication between mobile terminals and servers becomes more and more extensive.

Location-based service (Location Based Service, LBS) is to obtain the location information (geographical coordinates, or geodetic coordinates) of mobile terminal users through the mobile operator's wireless communication network (such as GSM network, CDMA network) or external positioning methods (such as GPS) ), a value-added service that provides users with corresponding services under the support of the geographic information system (Information System, GIS) platform.

Generally speaking, LBS is composed of a mobile communication network and a computer network, and the interaction between the two networks is realized through a gateway. The mobile terminal sends a request through the mobile communication network, and transmits it to the LBS service platform through the gateway; the service platform processes the request according to the user's request and the user's current location. And the result is returned to the user through the gateway. The service platform mainly includes WEB server (Web Sever), location server (Location Sever) and LDAP (Lightweight Directory Access Protocol) server, etc.

LBS includes two meanings: the first is to determine the geographical location of the mobile device or the user; the second is to provide various information services related to the location. LBS can be used as an information filtering technology to greatly improve the accuracy of information, but the premise is that the information itself and the geographical location are closely combined. Location is one of the important metadata.

LBS is divided into various types because of the different services provided. At present, several distinctive LBS application modes have been formed for different LBS service contents. These modes basically represent the current development trend and subdivision of LBS.

1. Leisure and entertainment

1. Check-in mode: The basic features of this mode are as follows:

1) Users need to actively sign in (Check-In) to record their location;

2) Encourage users to check-in through points, medals, lords and other honors to satisfy users' sense of vanity;

3) By cooperating with merchants, provide preferential or discounted rewards to users who have obtained specific points or medals, which is also the marketing of merchant brands;

4) By binding other social tools of the user to share the user's geographical location information synchronously;

5) Generate premium content by encouraging users to rate places (stores, restaurants, etc.).

The biggest challenge of this model is to cultivate the habit of users checking in (Check-In) every time they arrive at a location. And its business model is also relatively obvious, which can well carry out various forms of marketing and promotion for merchants or brands.

2. Monopoly game mode: The main purpose is the game life, which allows users to use their mobile phones to purchase virtual real estate and props in real geographical locations, and conduct consumption and interaction. A mode that truly integrates reality and virtuality. This mode is characterized by being more interesting, more playable and interactive, and more sticky than the Check-In mode. However, due to the need for virtual design of real estate and other locations, the development cost is relatively high, and Due to the strong regionality, the coverage speed cannot be very fast. In terms of business model, in addition to the joint merchant marketing that draws on the Check-In model, it can also provide value-added services, as well as product placement similar to Second Life (Second Life).

2. Life service type

1. Search for surrounding life services: a model combining Dianping.com or life information websites with geographic location services. The main experience lies in the practical nature of the tool, and the problem lies in the accumulation of information and the need for a wider coverage.

2. Combination with tourism: Tourism has obvious mobility and geographical attributes, and the combination of LBS and tourism is very suitable. Sharing strategies and experiences reflects a certain social nature.

3. Membership card and ticketing mode: Realize a one-card system, bundle the information of multiple membership cards, and at the same time, the electronic membership card can record consumption habits and information, so that users can fully experience the simple form and the aggregation of a large number of preferential information. These mobile Internet-based applications are slowly penetrating into all aspects of life services, making life more convenient and fashionable.

3. Social type

1. Make friends by location, instant messaging: Different users build user associations because they are in the same geographic location at the same time.

2. Small communities based on location.

4. Commercial type

1. LBS+group buying: Both have regional characteristics, but group buying has its own differences. The user goes to some local contracted merchants, and uses the mobile app to check in after arriving. When the number of Check In reaches a certain amount, all users who have checked in can get a certain discount or discount.

2. Preferential information push service: Provide users with geographic location-based preferential information push service. The profit model is to realize the profit sharing through cooperation with offline merchants.

3. In-store mode: Attract users to designated shopping malls, and give them virtual points that can be exchanged for commodities or gift certificates after completing the designated behavior.

To sum up, the LBS positioning + service model is destined to meet at least two conditions for the development of LBS: to determine your location; to determine your purpose (service). In LBS, location (Location) is the foundation, and service (Service) is the key point.

1. Determine your location

For location-based services, it is very important to have mobile terminals that can be accurately positioned. And this terminal, in addition to being able to determine the location, must also have a good application expansion function, because LBS can only make a difference if it is integrated with applications and can be viewed and browsed anytime and anywhere.

1. The number of smartphones supported

The scalability of smartphones, the system loaded on smartphones have good support for applications, the number of smartphones determines the richness of application software, and the richness of applications determines the range of user groups and audiences. Therefore, the popularization of smart phones has a very important prerequisite for the development of LBS, because after all, LBS is also a service based on geographical location, and these services must become applications integrated on mobile terminals to exert their attractiveness.

2. Smartphone GPS application

Compared with ordinary mobile phones, smart phones have always had very good support for GPS positioning and navigation due to the good application performance of their intelligent systems. Moreover, the current trend is that most smart phones can be equipped with GPS modules, and an important step in LBS is to determine the user's location, which undoubtedly has a very large role in promoting the development of LBS.

The key core of LBS service is location and geographic information, both of which complement each other and are indispensable. A longitude and latitude location does not mean anything for normal use, it must be placed in a geographic information, in order to represent a certain location, sign, orientation, etc., in order to be understood by people. Therefore, in addition to obtaining the location of the terminal through the positioning operation platform, the longitude and latitude must be converted into geographic information that users really care about through the GIS system, such as maps and route search results.

2. Determine your service

Once the location is determined, things will become much simpler and easier. Moreover, the main field of competition for LBS applications is also in this position: after knowing my location, what kind of service I need is the most concerned issue as a user. Whether the service provided is attractive enough to attract enough users to experience is the key to the success or failure of LBS application services. Because only enough people gather together, LBS location-based services can become lively, interesting and full of vitality.

In it, there is another point that cannot be ignored, that is good network support. Both positioning and services need network support to be realized. LBS needs relatively accurate positioning information and timely updated service information, and good network support is essential.

3. Merchant resource support

The application service is inseparable from the support of the merchant. The application only determines the location and then provides you with related services, so the support of merchant resources is also very important for the development of LBS.

In the process of developing LBS, the common problems encountered are as follows.

1. The penetration rate of smart phones is low. This will directly lead to relatively few audiences for LBS applications.

2. The limitation of the positioning accuracy of the smart phone terminal. LBS requires a very precise positioning strategy to describe the surrounding environment in more detail, and low positioning accuracy will lead to poor user experience of LBS applications.

3. The cost of positioning. Existing a class of positioning applications, the speed is very fast, and the display accuracy is also very high, but there is a very big problem: the GPRS traffic required for query and positioning is very huge. And LBS applications are all based on the mobile Internet, so the positioning cost must be considered.

4. Merchants lack awareness of promotion, and the Internet is flooded with trolls. In many LBS application services, the status of merchants is also very important. The ultimate purpose of users using LBS is to find the services they are interested in. The close cooperation between all merchants and application providers is particularly important. LBS aims to guide high-quality merchants to intended users, and merchants can also achieve brand promotion through this, which is also a mutually beneficial and win-win thing. However, what is shown is that most merchants lack awareness in this regard, resulting in too few high-quality service providers, which leads to the loss of users. Or there are a large number of trolls on the Internet, using various means to make their services get higher scores in the application, but the actual quality has not been followed up, which leads to user distrust.

All in all, in the prior art, even if the mobile phone itself can be positioned or can be assisted in positioning, for some applications, the positioning accuracy is not accurate enough, thus causing great restrictions on the application of LBS services.

Contents of the invention

The purpose of the present invention is to provide more accurate positioning services according to the user's historical behavior on the website, for example, according to the POI (point of interest), time and other information corresponding to the user's previous UGC (User Generated Content) behavior, combined with the current The longitude and latitude of the location and the previous behavior information provide more accurate user location.

According to one aspect of the present invention, a method for correcting the positioning of a mobile terminal is provided, comprising the steps of: recording the behavior information of the mobile terminal; determining the correction range according to the position information corresponding to the behavior information and the positioning information of the mobile terminal; when When the positioning information of the mobile terminal enters the correction range again, the position of the mobile terminal is corrected.

Detailed ways

With the development of mobile communication technology, the concept of Point of Interest (POI) originated in the field of geographic information system (GIS for short) began to be applied in the field of mobile communication. POI generally contains four aspects of information: name, category, longitude, and latitude.

Subsequently, a mobile POI system appeared, which is a mobile positioning service. Specifically, mobile POI is a location-based service. This service includes a server system and a client application. The client application is developed for the mobile phone platform. The main feature of the service is to allow users to Share location information.

The mobile POI system consists of a server and a client program that provide maps and user location information. The mobile POI system integrates and applies a variety of positioning technologies, including GPS, mobile network-assisted positioning, and user manual positioning.

The goal of the mobile POI system project is to create a platform that allows users to freely share their geographic location and related information with each other. A POI refers to a geographic location that contains some related specific information. POIs can contain information on different types of objects (such as restaurants, bars or parks), including locations, text descriptions, pictures and comments from users. Each POI is categorized and belongs to a certain community and a certain category. Categories are used to distinguish different POIs, such as restaurants, bars, shops, and so on. When the user is adding a POI, he can choose which category it belongs to. The purpose of setting categories is to allow users to better filter out POIs that are not of interest, and only view POIs that they care about. The mobile POI system has two different user interfaces, the mobile phone and the web interface.

The client application of the mobile POI system is specially developed for the mobile phone platform. Users can switch back and forth between different POIs displayed on the current map to view relevant information of each POI. After POIs are displayed on the map, users can filter these POIs by selecting a certain category, and only keep the POIs they care about. By clicking on a certain POI in the map, the user jumps to the information display page of the POI. Users can choose to add comments or view text comments written by other users on the POI. On the map page, the user can zoom in or out of the map, move the map or select another location to display a different map. Users can also add their own POIs. The steps for the user to add a POI are to select a certain position on the map with the cursor first, then select a certain category, and then input a name and a text description for the selected position point. On some models of phones, there is an additional option to add a picture taken with the phone's built-in camera to the POI.

The mobile POI system has two independent web interfaces, one for end users and the other for system administrators. The end-user web interface feeds back different community information on the mobile client platform to the user, viewing and editing all information in a very concise way. The system management web interface is based on the end-user web interface, plus some system management functions.

Mobile POI system includes mobile phone client and server system. The server-side system consists of two main databases, a communication interface with the mobile phone client and an external map server. A custom communication protocol is used to establish a connection between the server and the client.

The server side of the mobile POI system is composed of database, Web server and POI application server. The POI application server is responsible for processing the request sent from the mobile phone, and it establishes a connection with the remote map server at the same time.

The system has two different mobile phone clients: one is a mobile phone with GPS global positioning system, and the other is a mobile phone without GPS. The mobile phone with its own GPS can provide more accurate location information to the POI application server. Another type of client mobile phone does not have a GPS device, and this class of client mainly relies on the self-learning system (self-learning system) in the POI application server to locate, or the user manually inputs his current location on the map. In short, positioning is mainly achieved through the assistance of mobile network operators or the use of GPS global positioning system.

A technical solution for correcting the positioning of a mobile terminal according to an embodiment of the present invention will be described below with reference to FIG. 1 and FIG. 2 .

When a user of a mobile terminal displays or provides his own DIY content to other users on a specific POI through the Internet platform, it is called UGC. However, those skilled in the art can understand that the behaviors of users and/or mobile terminals mentioned in the present invention include but not limited to UGC behaviors, and the corresponding behavior information also includes but not limited to UGC behavior information.

The user carries a mobile terminal 104, and the mobile terminal 104 is, for example, a mobile phone, a personal digital assistant (Personal Digital Assistant, PDA), a palmtop computer, a laptop computer, a tablet computer, a POS machine, a smart computer, and the like. The server 108 communicates with the mobile terminal 104 through the network, and the server 108 may be a general-purpose server or a dedicated server.

In this specification, the location of the mobile terminal 104 refers to a location ranging from tens of meters or hundreds of meters to thousands of meters. The representation of the above location range may be precise perimeter information, or precise information of one or more points and related precision information, and of course other representations known in the art may also be used.

POI 106 has explicit location information. This kind of location information is generally fixed, but in some cases, it may not be fixed, but it is still clear.

When the user is at the POI 106, the content created by himself may be applied to various network services through the Internet for the POI 106 through the mobile terminal 104. User behavior records include but are not limited to user-created content (including but not limited to location, text, photos, audio, and video content), shared content from external sites, interactions between the user and other users, and previous location-related Information. Network services include but are not limited to: friend social networks (such as Facebook, Renren (Xiaonei), QQ Alumni, etc.), most of the friends on these sites also know each other in reality, users can change status, post logs, post photos, Share videos, etc., so as to understand the dynamics of friends; video sharing networks (such as YouTube, Youku, Tudou, etc.), such websites are centered on uploading and sharing videos, and there are also friend relationships, but compared with friend networks, this kind of The relationship is very weak, and it is more combined through common preferences; photo-sharing networks (such as Flickr, Youpai.com, etc.), the characteristics of such websites are similar to video-sharing websites, except that the main body is photos, pictures, etc.; knowledge-sharing networks (such as Baidu Encyclopedia, Baidu Zhizhi, etc.), this type of website is to popularize the knowledge of netizens and solve problems for netizens; communities and forums (such as Baidu Tieba, Tianya Community, etc.), users of such websites are often attracted by common topics. Gather together; Weibo (such as Twitter, Sina Weibo, etc.), Weibo should be the most popular Internet application at present, it solves the problem of real-time update of information, and the popularity of mobile phones and other portable devices makes every Weibo user Potential to be the first live publisher.

In step S202, the behavior information of the mobile terminal 104 is recorded. In step S204 , the correction range is determined according to the location information corresponding to the behavior information and the positioning information of the mobile terminal 104 .

Specifically, the behavior of the mobile terminal 104 may correspond to a definite location, for example, the UGC behavior of the mobile terminal 104 at the POI 106 corresponds to the definite location of the POI 106. Meanwhile, the positioning information of the mobile terminal 104 can be obtained by the mobile terminal 104 itself, which is called automatic positioning, for example, the GPS information is obtained through the GPS module of the mobile terminal 104; the positioning information of the mobile terminal 104 can also be manually input by the user The positioning information of the mobile terminal 104 can also be assisted in positioning by means of the server 108 or other equipment (not shown) that can be used for positioning. Optionally, the mobile terminal 104 may also collect location information indicating its location by contacting or short-range communication with a device whose location is known. Means of contact or proximity communication with devices of known location include, but are not limited to, RFID, barcode scanning, and QR code scanning. When the behavior of the mobile terminal 104 corresponds to location information and location information of the mobile terminal 104 obtained through self-location, manual input, or assisted positioning, the correction range is determined based on the two. That is to say, although the positioning information of the mobile terminal 104 shows that the mobile terminal 104 is in a certain position, since the position of the POI 106 is more accurate, it is reasonable to think that the mobile terminal 104 is actually at the position corresponding to the POI 106, or is in its position information. Somewhere between the corresponding location and the POI 106 location.

In step S206, when the positioning information of the mobile terminal 104 enters the determined correction range again, the position of the mobile terminal 104 is corrected. The correction may be to correct the position of the mobile terminal 104 to the position corresponding to the position information corresponding to the aforementioned behavior information. Optionally, the correction may also be to correct the position of the mobile terminal 104 to a position within the correction range that is different from the position information corresponding to the aforementioned behavior information. For example, the current positioning result can be properly adjusted according to the algorithm, and it may eventually be positioned between the point positioned by the mobile terminal 104 and the previously reported POI 106 point.

Since user behavior is closely related to time, FIG. 3 shows a preferred embodiment that considers time factor.

In step S302, the behavior information of the mobile terminal 104 is recorded, and the behavior information also includes time information. In step S304 , the correction range is determined according to the location information corresponding to the behavior information and the positioning information of the mobile terminal 104 . In step S306, when the positioning information of the mobile terminal 104 enters the determined correction range again, and the time is within a corresponding time segment, the position of the mobile terminal 104 is corrected. For example, if POI

106 is a bar, and the time corresponding to the behavior of the mobile terminal 104 at POI 106 is 9 o'clock in the evening, so if the positioning information of the mobile terminal 104 enters the determined correction range again, but the time is 9 o'clock in the morning, then it is wrong for the mobile terminal 104 The position is corrected.

As shown in Figure 4, the device 400 for correcting the positioning of the mobile terminal 104 according to an embodiment includes: a behavior information recording device 402 for recording the behavior information of the mobile terminal 104; a correction range determination device 404 for The position information corresponding to the information and the positioning information of the mobile terminal 104 determine the correction range; the position correction means 406 is used to correct the position of the mobile terminal 104 when the positioning information of the mobile terminal 104 enters the determined correction range again.
