Summary

MAP primary use is to allow calls to be delivered to mobile subscribers. Unlike with fixed-line networks, the subscriber's location cannot be determined from the numbering scheme that is used in the network. Therefore, the subscriber's location must be known in real-time so a call can be connected to the nearest switch to the mobile subscriber. MAP keeps track of a mobile subscriber and provides other functionality, including allowing mobile subscribers to send alphanumeric two-way text between handsets; this is known as SMS. MAP also provides mobile operator's with the functionality to manage a subscriber's subscription so that services can be added and removed in real-time.
