Description

Mobile map mobile terminal platform embedded in mobile terminal

technical field

The invention relates to a mobile phone map mobile terminal platform embedded in a mobile terminal, in particular to a mobile phone map mobile terminal platform built in a mobile terminal using a map browser and a map engine.

Background technique

With the progress of society, people's activity scope is increasing day by day, location-based services appear and are gradually accepted by users. At the same time, with the development of wireless communication technology, the wireless communication network can already have the function of providing different precision positioning, such as Cell-ID, E-OTD, A-GPS and so on. The penetration rate of wireless communication is also increasing constantly. Therefore, ordinary users can use location-based related services through wireless communication networks through wireless terminals, such as positioning, information point query, navigation and other functions.

In the prior art, among the implementation schemes based on wireless networks, currently available methods include SMS, MMS, and WAP browsing. The existing location-based services provided on mobile terminals are not developed for location-based services. The user's experience is not good, and it cannot provide users with accurate and real spatial information and attribute information with both pictures and texts. The SMS method means that the user sends formatted information to the service code, and the SMS center or SMS service provider sends the result to the user in text form according to the request content and combined with the user's location information. The disadvantage of this solution is that the user's business experience is not good, and the text content cannot be intuitively felt by the user like a map. The MMS method means that the user sends format information to the service code, and the MMS center or MMS service provider sends the result to the user in text or graphic form according to the content of the request and in combination with the user's location information. The disadvantage of this solution is that the user interface is not friendly, professional and interactive. The WAP mode means that the user browses the map and inquires about relevant information by visiting the corresponding location service website. The disadvantage of this solution is that the WAP browser is not developed for location services and does not support vector graphics; the steps to use are complicated and the user experience is not friendly enough.

Human beings have entered the information age, and the rapid development of the IT industry and the communication industry has made human beings move towards the so-called "TIMES" (Telecommunications, Information-technology, Multimedia, Entertainment and Security). With the upgrading of mobile communication transmission technology from the first generation to 2G, 2.5G, 3G, and will inevitably develop to faster data transmission speed, the world's first-class software developers cooperate with large mobile phone production companies to integrate some functions of computers Adding it to a mobile phone enables it to provide data and image services in addition to transmitting sound information, making the mobile phone gradually become a "mobile computer" and "wireless network". And with integration becoming the leading trend of applications, geographic information systems (Geographic Information Systems, GIS) provide spatial analysis and visualization capabilities for virtually all computing environments.

Geographic Information Systems (GIS) has been integrated into the mainstream of Information Technology (IT) and has become an important part of IT. The rapid development of GIS (Geography Information System, geographic information system) technology makes people more contact and use it. For example, electronic maps, Internet-based public multimedia shopping guide system, car GPS self-navigation system, etc., all of which make the demand for geographic information surge. GIS is a high-tech that integrates computer graphics and databases to store and process spatial information. It organically combines geographic location and related attributes, and outputs spatial information and its attribute information to users in an accurate, authentic, graphic and textual manner according to the needs of users. , to meet urban construction, engineering survey, construction and people's requirements for spatial information, with its unique spatial analysis function and visual expression function, to carry out various auxiliary decision-making. The above-mentioned characteristics of GIS make it an advanced tool for solving problems that is different from traditional analysis methods.

With the large capacity and high speed of communication network (including wired and wireless network), GIS has become a distributed heterogeneous system on the network. Through WAP server and mobile GIS, LBS and MLS, namely location-based service and mobile positioning service, which have emerged at present, highlight this changing trend, that is, GIS has become an information service tool for everyone in the whole society. Users have more and more demands on implementing GIS applications on mobile terminals, so it has become a trend to provide GIS-based location services to mobile terminal users. my country currently has more than 200 million mobile phone users. If each person pays 10 yuan per month for MLS, the annual output value of the country will reach 24 billion. It can be predicted that in the near future, geographic information services will be able to provide 4A services (geo-in-formation for anyone and anything at anywhere and anytime) anytime, anywhere. Therefore, it is a new requirement to propose a mobile map mobile terminal platform on the mobile terminal to provide various location service services to users.

With the rapid development of computer and network technology, embedded systems have been paid attention to because of their small size and high speed. Embedded systems are widely used in handheld computers, PDAs, mobile phones, navigation equipment, and information appliances. As an important embedded system application software, the embedded browser plays an indispensable role in the embedded system because of its versatility, expansibility, and ease of industrial division of labor.

In order to meet the needs of users, the mobile map platform is aimed at smartphones with different operating systems, and customizes the mobile map engine core, business framework, and service modules with the same interface and different code implementations. The platform provides users with mobile phone positioning, location information query, and various location-related LBS new services. The mobile map platform consists of three parts: mobile map mobile terminal platform, mobile map service middle-end platform, and mobile map service-end platform. Providers of mobile map platforms need to develop mobile map kernels and business implementation frameworks implemented by different codes; SP service providers also need to develop specific business modules with different codes (C++ level) for different types of smartphones. This will cause the following problems: SP provider technical personnel are required to have higher requirements, the generated system code is too large, the system cannot shield the error transmission of different SP providers, and users are cumbersome to use, etc. For different mobile phone operating systems and different versions, fully realize the LBS function on the mobile terminal, including the map engine, user interface, and system configuration information. There are many disadvantages, such as numerous, complex upgrades, high user costs; therefore, in order to solve the above problems, the map browser in the mobile map mobile terminal platform of the mobile phone is necessary. Also do not have corresponding mobile terminal map browser technical scheme at present.

Mobile GIS (Geographic Information System), the application field is that customers obtain the information required by various households with geographical attributes such as their geographical location and surrounding transportation, commerce, catering, entertainment, hospitals, etc. through wireless communication tools. have a broad vision of application. However, the existing GIS engine cannot support multiple mobile terminal operating systems, the data structure is not compact enough and does not have an interface that can be interactively called with the browser; , the GIS engine can no longer satisfy the management and display of change information in this area. Therefore, GIS engines in the traditional sense need to be extended.
