什么是LBS?

A location-based service (LBS) is an information and entertainment service, accessible with mobile devices through the mobile network and utilizing the ability to make use of the geographical position of the mobile device.

LBS services can be used in a variety of contexts, such as health, work, personal life, etc. LBS services include services to identify a location of a person or object, such as discovering the nearest banking cash machine or the whereabouts of a friend or employee. LBS services include parcel tracking and vehicle tracking services. LBS can include mobile commerce when taking the form of coupons or advertising directed at customers based on their current location. They include personalized weather services and even location-based games. They are an example of telecommunication convergence.

This concept of location based systems is not compliant with the standardized concept of real time locating systems and related local services (RTLS), as noted in ISO/IEC 19762-5 and ISO/IEC 24730-1.

    LBS（Location-Based Services），即无线定位业务又称为位置业务。LBS是由移动通信网提供的一种增值业务，通过一组定位技术获得移动台的位置信息（如经纬度坐标数据），提供给移动用户本人或他人以及通信系统，实现各种与位置相关的业务。

    由于二代系统数据传输能力较低，因此所能提供的定位服务类型也受到限制。3G系统在数据传输能力方面比2G系统有很大提高，为向用户提供更丰富的信息提供了网络带宽的保证，使一些信息量较大的定位业务通过无线网络实现成为可能，如地图显示、实时导航甚至3D地图服务等。
