Clement Thompson. Vishal Kottarathil. When the database has got full the oldest record in the database is overwritten when a new record is stored. A record is valid for Precise Paging for maximum 24 hours.

Validity is checked when the record is found during paging procedure. Each BCSU contains record of different mobiles. Database is copied to spare BCSU in controlled switchover. If that is not available, then it uses the location information sent by the MSC in the paging message.

This indication is used also for Paging Coordination feature. This is because load in Air interface gets decreased and therefore more successful pagings can be made. Precise Paging is sent at maximum to 33 cells instead of all cells in LA or RA, hence load in the Air interface gets decreased. The indications are sent when either Precise Paging or Paging Coordination or both the features are active. Acti- vating or deactivating the other feature while the other one is still active does not affect the signaling load.

Per- formance of Precise Paging feature starts to increase gradually after the feature has been switched on. The location database starts filling up with the MS's location informa- tion. Once the database has got full, the generated paging load depends directly on the count of neighboring cells defined for the cells and how often MSs are Precise Paged successfully.

Precise Paged area comprises at maximum 33 cells when 32 neighbors are defined for the cell. Paging is normally made either in LA or RA level and the areas are usually the same size. Savings are even higher when there are fewer neighbors defined for cell or known location is closer to LA or RA border.

Paging is always conducted inside a LA or RA. On the other hand, broadcasted paging messages in the message bus are much shorter than the paging messages broadcasted in normal paging method. Recommended value is the same as repaging delay in MSC side. This parameter has effect only when Precise Paging is enabled. Table 4 New parameters for Precise Paging Cont.

Precise Paging Number of times when paging has been sent to the rest of the cells in the Expanded original paging area when last known location of a MS was in this cell and the MS was first Precise Paged. The counter value is updated when there is no response to paging request from MS when precise paged after which the paging is expanded to rest of cells in the original paging area.
