Abstract

A Virtual Mobile Location Area (VMLA) personalized to the particular roaming habits of a mobile phone user, employing predetermined grouping of cells arranged in the order of likelihood that the mobile phone users will be in that grouping.

Claims

1. In a cellular telephone network comprising a plurality of local areas, each local area comprising a plurality of base stations and having associated therewith a home location register to indicate which mobile stations in the network are registered in that particular local area, a method for locating mobile stations comprising:

determining the call habits of a mobile station;

determining the base stations that the habits of the mobile station indicate the mobile station will most likely use to initiate and receive calls;

arranging the cells that contain the base stations that the habits of the mobile station indicate the mobile station will most likely use to initiate and receive calls into a group, called a Virtual Mobile Location Area (VMLA), and assigning said VMLA to said mobile station, wherein said VMLA is only modified when the call habits of said mobile station indicate that said mobile station has entered a new cell, having a new base station contained therein, more than once; and

registering the mobile station with each home location register in the local area associated with every base station that the habits of the mobile station indicate will most likely be used by the mobile station.

2. In a cellular telephone network comprising a plurality of local areas, each local area comprising a plurality of base stations and having associated therewith a home location register to indicate which mobile stations in the network are registered in that particular local area, a method for locating mobile stations comprising:

determining the call habits of a mobile station;

determining the base stations that the habits of the mobile station indicate the mobile station will most likely use to initiate and receive calls, arranging the cells which contain said base stations into a group, called a Virtual Mobile Location Area (VMLA), and assigning said VMLA to said mobile station, wherein said VMLA is only modified when the call habits of said mobile station indicate that said mobile station has entered a new cell, having a new base station contained therein, more than once;

registering the mobile station with each home location register in the local area associated with every base station that the habits of the mobile station indicate will most likely be used by the mobile station;

arranging into groups the base stations remaining in each local area which have not already been determined to be most likely used by the mobile station;

determining in which group of remaining base stations the mobile station would next likely be; and

repeating the previous step for each group of base stations so that a paging order of groups is established, said paging order proceeding from the most likely group to the least likely group.

3. The cellular telephone network of claim 2, wherein said VMLA is defined as a first group of base stations in said paging order.

4. The cellular telephone network of claim 3, wherein the local area in which said mobile station is customarily stationed is defined as a second group of base stations in said paging order, wherein said second group of base stations excludes said first group of base stations.

5. The cellular telephone network of claim 4, wherein the remaining base stations comprise a third group of base stations in said paging order.
