TH17766B - Methods for adapting the HLR database in the mobile phone system. - Google Patents

Abstract

Methods used to calibrate one or more HLR databases used in the system. GSM mobile phones HLR modifications (HLR1) were requested by submission. New messages and settings (Reset-message), which identifies the associated HLR database. To a number of VLR databases (11). Loss in performance or capacity of The process of the VLR database is relatively minimal. For this reason, the time point (t: HLR1) where the message and the reset and the time point (t: MS1) where the radio contact is This occurs with mobile stations (MS1) and is recorded through each VLR value for each radio call between VLR and the mobile station. Request adjustment If it were true The timing of the previous radio communication between VLR and the mobile station is compared in VLR with the time point at which the message and the reset were received and where the HLR was adjusted with information from VLR when the previous radio call this Happened before the message was received and reset:

Claims (2)

1. A method used for tuning the value of one or more of the HLR databases. This is used in GSM cell phone systems where such database modifications are requested by transmission to a number of VLR databases, a special message that identifies the relevant HLR database. Where this is directed by recording and adjustment in each VLR (11) database and the time point (eg t: HLR1; t2) where the message is. Obtained from each HLR database (such as HLR1), notification, record keeping, and Adjustment for each VLR database (11) time point (eg t: MS1; t1, t3-t5) of each radio communication between the database and each mobile station (eg MS1, MS2) within the area where Covered by the VLR database at a specific time; VLR database search to ensure that mobile station is in the HLR database (eg HLR1), which requests adjustment by each radio communication between VLR database (11) and the mobile station (e.g. MS1). , MS2); When a mobile station (such as MS1) is in the HLR database (such as HLR1), adjustment and Comparison of any recorded time points (for example, t: MS1; t1, t3) of the earliest radio communications between the relevant VLR (11) databases. And mobile station Relevant in the VLR database with the recorded time point (eg t: HLR1: t2), where it is Such messages from the HLR database, where mobile stations are located; And HLR database-database modifications (eg HLR1), which requested an adjustment from the VLR database (11) when previous radio communications were premature. Where the message was received 2. The method described in Claim 1, directed by the HLR Database Adjustment, which requests the adjustment at all times, even when it occurs. There is no time point to notify and record. For radio communications that occurred immediately before Between VLR database and mobile station
