Abstract

A method for relocating a subscriber in a voice messaging system (VMS) which is connected with an extensive digital mobile network (GMS), including a plurality of mobile switching centres (MSC) and a home location register (HLR). In the method, VMS checks HLR repeatedly for the location of a subscriber and concludes on the basis of this information whether the subscriber has moved into the area of some other MSC for a period of time longer than a predetermined period of time and, in a positive case, the old VMS transfers the subscriber-related information to the new VMS, thus accomplishing the automatic relocation of the subscriber'"'"'s home station in connection with a new MSC.

Claims

1. A method for relocating a subscriber in a plurality of voice messaging systems connected with an extensive digital mobile network (GMS), including a plurality of mobile switching centres (MSC) each having a VMS associated therewith and a home location register (HLR), characterized in that, in the method, each VMS checks HLR repeatedly for the location of a subscriber and concludes on the basis of this information whether the subscriber has moved into the area of some other MSC for a period of time longer than a predetermined period of time and, if so, the old VMS transfers the subscriber-related information to the new VMS, thus accomplishing the automatic relocation of the subscriber'"'"'s home station in connection with a new MSC.

2. A method as set forth in claim 1, characterized in that said check for the location of a subscriber is effected periodically, at fixed intervals.

3. A method as set forth in claim 1, characterized in that forwarding of calls to a subscriber'"'"'s voice mail box is intercepted for the transfer of the subscriber-related information.

4. A method as set forth in claim 1, characterized in that said predetermined period of time is determined as a portion of the time spent within a new area relative to a certain time period.

5. A method as set forth in claim 2, characterized in that said predetermined period of time is determined as a portion of the time spent within a new area relative to a certain time period.
