Location area

Right!

A location area (LA) refers to a set of cells in a mobile communication system, and is an important part of the mobility management of a mobile station (or cell phone).

The role of setting the location area is to enable the mobile switch or mobile switching center (MSC) to know the location of the mobile station in time. When calling a mobile station, the mobile switching center searches in all the cells in the location area of the mobile station. Find the mobile station accurately.

The location area (LA) is stored in the user identification card (ie, SIM card) of the user's mobile phone. When the mobile phone roams in the network, if the location area in the SIM card is found to be inconsistent with the location area of the mobile network, it is sent to the network Location update message.

Each MSC / VLR service is divided into several location areas. The location area is a part of the MSC / VLR service area. A mobile station can move "freely" within a location area without performing location update processing. A broadcast message is transmitted in a location area to find mobile users and is a paging area. A location area only belongs to a certain MSC / VLR service area. With the location area identification code (LAI), the system can distinguish between different location areas. A location area contains several cells and may be related to one or several BSCs. It is a positioning and paging area.
