LCS

Hello,

Location services (LCS) are location based services, with the goal of obtaining information of where the mobile is (location information). With the standardization of the format of the location information (eg latitude and longitude) the operators can offer different types of services.

And these services can be used in several ways, as for pricing, legal requirements as intercept, location services, emergency call services, among others.

Standardization includes aspects such as reliability, priority, security, and privacy.

In addition it also takes into account the technology used to obtain the information, which can be based on the network (network-based), or based on the mobile (mobile-based).

• In the case of technology network-based, the operator must install equipment that can perform this function.

• In the case of mobile-based, the location information is obtained by the mobile itself, such as through a GPS (Global Positioning System) chip therein.

A common way to represent these aspects is through a graph of Accuracy versus Availability. Depending on the technology used, a certain percentage of calls must be located within a certain distance.

Thanks
