Once the mobile users leave the VLR, reassemble the control area in another VLR registration, the original VLR will be cancelled temporary record of the mobile user data. Therefore, VLR can see as a dynamic user database.

In one MSC area is controlled by the mobile user roaming responsible for the regional visit position when a register, and mobile station appeared in one position zone, VLR will start position to update the program, VLR contained within its jurisdiction appear the mobile user data.

Mainly includes the following information in VLR unit
