Method of estimating the need of capacity for different parts of a cellular radio system
First Claim
1. A method of estimating the need of capacity for different parts of a cellular radio system divided into location areas, mobile stations being arranged to send location update messages to the other parts of the system in predetermined situations, comprising:
- identifying a predetermined geographical area for which the operator wishes to estimate the need of capacity, defining a new location area covering said area, defining said new location area to be the location area of the base stations located in said area during the time of estimating the need of capacity, monitoring location update messages transmitted from the new location area, keeping statistics on the location update messages detected, these statistics including an information on at least the number of location update messages received from the area, estimating the need of capacity for the area on the basis of the data in said statistics, and removing said new location area from the system.

Abstract
This invention relates to a cellular radio system including a mobile telephone exchange, base stations and mobile stations, the geographical area covered by the cellular radio system being divided into location areas and the mobile stations being arranged to send location update messages to the base stations. In order that the number of mobile stations located in the area may be ascertained more accurately than before, the system includes storing means for monitoring location update messages and for storing data contained in the location update messages in a memory means, and means for transmitting the data stored in the memory means further to the operator of the system, for an estimation of the need of capacity for the different parts of the system on the basis of the stored data.

5. A cellular radio system, the geographical area covered by the cellular radio system being divided into location areas, said system comprising:
-
a mobile telephone exchange, base stations, mobile stations arranged to send location update messages by radio to base stations of the system in predetermined situations, a base station controller controlling the function of a plurality of said base stations, storing means arranged in said base station controller for monitoring location update messages received by the base stations and for storing data contained in the location update messages in a memory means in response to detecting a location update message, and means for transmitting the data stored in the memory means further to an operator of the system for an estimation of the need of capacity for the different parts of the system on the basis of the data stored in the memory means. - View Dependent Claims (6, 7)
