Abstract
A method for recovering group data between mobile systems, which incorporate at least one first mobile system, at least one second mobile system, and mobile stations, the method comprising the steps of maintaining group data in a first database of the first mobile system, maintaining group data in a database of the second mobile system. In the method, a recovery request is made for recovering the group data, the second mobile system generates one or more virtual attachment requests for the first database of said group, the second mobile system transmits the virtual attachment request to the first database of the first mobile system, in response to the first virtual attachment request, the group data are updated in the first database.
Claims14
A method for recovering group data (GD) between mobile systems (S1, S2, S3), which incorporate at least one first mobile system (S1), which comprises a first database (DB1), at least one second mobile system (S2), which comprises a second database (DB2), and which mobile systems incorporate mobile stations (MS1, MS2), the method comprising the steps of
- maintaining (302) group data (GD) in said first database (DB1) of said first mobile system (S1),
- maintaining (303) said group data (GD) in said second database (DB2) of said second mobile system (S2),
- a recovery request is made (304) for recovering group data (GD),
- characterized in that the method further comprises the following steps:
- the second mobile system (S2) generates (306) one or more first virtual attachment requests for the first database of the first mobile system (S1),
- the second mobile system (S2) sends (307) the first virtual attachment request to the first database (DB1) of the first mobile system (S1),
- in response to the first virtual attachment request the group data (GD) are updated (308) in the first database (DB1) and wherein
- from the second mobile system at least one virtual attachment request is sent per every group of the first mobile system found in the second database of the second mobile system.

- in response to the first virtual attachment request the group data (GD) are updated (308) in the first database (DB1) and wherein
- from the second mobile system at least one virtual attachment request is transmitted per every subscriber attached to the group of the first mobile system, found in the second database of the second mobile system.
