System and method for maintaining profile information in a telecommunications network
First Claim
1. In a telecommunications network including a plurality of systems for serving a telecommunications device, wherein said plurality of systems are coupled to a home system, a method comprising the steps of:
- receiving a message from a first one of said plurality of systems at said home system when said telecommunications device registers with said first one of said plurality of systems after roaming from a second one of said plurality of systems to said first one of said plurality of systems;
determining if said telecommunications device had registered with said first one of said plurality of systems during a predetermined period of time preceding said registration of said telecommunications device with said first one of said plurality of systems;
not sending a profile associated with said telecommunications device in response to receipt of said message by said home system if said telecommunications device had previously registered with said first one of said plurality of system; and
sending said profile associated with said telecommunications device from said home system to said first one of said plurality of systems, in response to receipt of said message if said telecommunications device had not previously registered with said first one of said plurality of systems within said predetermined period of time preceding said registration of said telecommunications device with said first one of said plurality of systems.

Abstract
A system and method is implemented within a telecommunications network, such as a cellular telephone network, for maintaining updated profile information for each mobile subscriber registered within the network. Updated profile information about each mobile subscriber is maintained within a particular mobile switching center currently communicating with the particular mobile subscriber. This process is performed with minimal utilization of bandwidth between the various mobile switching centers in the telecommunications network by maintaining subscriber service profile information within mobile switching centers, even though the associated mobile subscriber has roamed from that mobile switching center. When the subscriber service profile information is updated, then the subscriber service profile information is downloaded to a mobile switching center currently serving the mobile subscriber.

11. A telecommunications network comprising:
-
a plurality of systems operable for serving communication needs of a telecommunications device; a home system operable for controlling said telecommunications network, said plurality of systems coupled to said home system, wherein said home system further comprises; circuitry operable for maintaining a record of a portion of said plurality of systems with which said telecommunications device had previously registered; and circuitry operable for sending a profile associated with said telecommunications device to a first one of said plurality of systems in response to receipt of a message from said first one of said plurality of systems that said telecommunications device has registered with said first one of said plurality of systems after roaming from a second one of said plurality of systems to said first one of said plurality of systems, wherein said profile is sent to said first one of said plurality of systems when said first one of said plurality of systems is not one of the record of said portion of said plurality of N systems. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. In a cellular communications network comprising first and second systems, a method comprising the steps of:
-
receiving a registration message from a cellular telephone by said second system; sending a registration notification message indicating that said cellular telephone has registered with said second system from said second system to said first system; determining if said second system is included in a stored record in said first system to indicate that said cellular telephone has previously registered with said second system; and not sending a profile associated with said cellular telephone to said second system when said stored record indicates that said cellular telephone has previously registered with said second system. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
