Proprietary Mobile Paging Overview Mobile paging is the mechanism that informs a mobile unit that an incoming call is attempting to reach the unit. Pages are sent from the base stations to the mobile unit on the paging channel. As the number of wireless subscribers increases, paging channel occupancy becomes increasingly important and effective management of that resource is required. This tutorial provides information on monitoring and adjusting the paging strategy within a network to optimize call delivery success rates while efficiently using the paging channel.

Proprietary Basic Paging Techniques The two basic categories of paging techniques are geographic based paging and technology based paging Geographic paging coverage determines which cells get a page request based on physical location in the network. Technology based paging coverage determines which cells get a page request based on digital/analog capabilities of the target mobile unit and the system. Digital? Analog? ? ? ?

Proprietary Geographic Paging Geographic paging can be applied as: Flood Paging send page requests to every cell in the MSC’s flood page list. Directed Paging send page requests to only the cells at the “last seen” MSC. Visited MSC Direct Paging- send page requests to cells in the home MSC Home MSC Multiple MSCs One MSC

401-610-631 Page 7 © 2002, Lucent Technologies Lucent Technologies Inc. Proprietary Geographic Paging: Directed Paging Directed paging is also known as “last seen” or “smart” paging. The mobile is paged only at the MSC where the mobile was last seen. Autonomous Registration (AR) and Enhanced Registration (ER) are used to keep the MSC informed of the mobile’s location. Directed paging can make more efficient use of the paging channel if the AR/ER location information is reliable. During an overload condition, the AR/ER information may be out-of-date due to the lower priority of AR/ER messages, and thereby reduce the effectiveness of directed paging.
