Who can tell me what LBS really means?

LBS refers to location-based services (LBS).

The location information (geographical coordinates or geodetic coordinates) of mobile terminal users is obtained through the radio communication network (such as GSM network and CDMA network) or external positioning mode (such as GPS) of telecom mobile operators, and with the support of GIS (Geographic Information System) platform, value-added services of corresponding services are provided for users.

Mobile location service is considered as one of the killer services after SMS, with huge market scale and good profit prospects, but the actual progress is relatively slow. However, with the improvement of the industrial chain, the mobile positioning and location service market is expected to grow day by day.

From 2008, the global LBS operation market will begin to accelerate, but at the same time, we should pay great attention to the balance between business and network performance, and ensure the development of business as much as possible while ensuring network performance.

Extended data:

LBS business functions mainly include:

1, requiring high coverage. On the one hand, the coverage is required to be large enough. On the other hand, the required coverage includes indoors. Users use this function indoors most of the time, from high-rise buildings to underground facilities, every corner must be covered.

According to the different coverage, it can be divided into three kinds of coverage location services: in the whole local network, it covers some local networks and provides roaming network services. In addition to considering coverage, network structure and dynamic environment factors may also make telecom operators unable to guarantee services in local networks or roaming networks.

2. Positioning accuracy. Mobile phone positioning should provide different accurate services according to different service needs of users, and can provide users with accurate choices. For example, the probability of positioning accuracy within 50 meters introduced by FCC in the United States is 67%, and the probability of positioning accuracy within 150 meters is 95%.

On the one hand, the positioning accuracy is related to the positioning technology adopted, and on the other hand, it depends on the external environment for providing services, including the radio propagation environment, the density and geographical location of base stations, and the equipment used for positioning. ?
