Abstract

According to the inventive method, an incoming call that is directed to a subscriber terminal (Tln 1) allocated to a subscriber group (Tln1 to Tln n) is signaled to the subscriber terminal (Tln 1) called and additionally to at least one subscriber terminal (Tln A3 to Tln An) that is located outside the signaling transmission range of the subscriber terminal called.

Claims

1. A method for signaling an incoming call directed to a subscriber terminal associated with a subscriber group, comprising:

optionally accepting another subscriber terminal associated with the subscriber group instead of the subscriber terminal being called; and

signaling the incoming call to the called subscriber terminal and to at least one subscriber terminal which is located beyond the signaling range of the called subscriber terminal, wherein

the subscriber terminals associated with the subscriber group and located beyond the signaling range of the called subscriber terminal are associated with subgroups within which the incoming call is additionally signaled to at least one subscriber terminal in a respective subgroup.

2. The method as claimed in claim 1, wherein the additional signaling to the at least one subscriber terminal located beyond the signaling range of the called subscriber terminal is carried out in parallel or with a time delay for signaling the incoming call to the called subscriber terminal.

3. The method as claimed in claim 1, wherein the at least one subscriber terminal located beyond the signaling range of the called subscriber terminal is defined in advance for receiving the additional signaling within the subscriber group.

4. The method as claimed in claim 1, wherein the subscriber terminals associated with the subgroup are located within the signaling range of the at least one subscriber terminal to which the incoming call is additionally signaled.

5. The method as claimed in claim 1, wherein one or more subscriber groups are defined by the contents of a table which is stored in a switching center in a telecommunications network.

6. The method as claimed in claim 5, wherein a subscriber terminal is associated with a subscriber group by entering a call number in table fields which are provided for the subscriber group within the table.

7. The method as claimed in claim 5, wherein at least one subscriber terminal to which the incoming call is signaled is defined by the contents of another table which is stored in the switching center and is linked to the table which defines that subscriber group.

8. The method as claimed in claim 5, wherein the table which defines the subscriber group, and the another table linked thereto, are stored in a central database in the switching center.

9. The method as claimed in claim 7, wherein at least the call number of the at least one subscriber terminal to which the incoming call is signaled is entered in the another table.

10. The method as claimed in claim 9, wherein the subgroups are formed by grouping call numbers, which are entered in the another table of subscriber terminals, within which subgroups at least one call number is identified as a special call number with a subscriber terminal having the incoming call as the signaled.

11. The method as claimed in claim 10, wherein, after each incoming call, at least one call number other than the at least one already identified call number is identified within a subgroup in accordance with a predetermined sequence or a sequence which is defined by a random principle.

12. The method as claimed in claim 10, wherein, in the table which defines the subscriber group, at least one call number is identified for additional signaling of the incoming call which is directed to the subscriber terminal to the at least one subscriber terminal which is located beyond the signaling range.

13. The method as claimed in claim 1, wherein the call number of the called subscriber terminal and/or of the calling subscriber terminal is indicated on a display for the at least one subscriber terminal to which an incoming call is signaled.

14. The method as claimed in claim 1, wherein entries in the tables are administered from one subscriber terminal.

15. The method as claimed in claim 14, wherein administration of the entries is allowed after a subscriber authorization process has been successfully performed.

16. The method as claimed in claim 1, wherein the association of a subscriber terminal with a subscriber group and/or with any subgroup is applicable within a time interval which is set or within a recurrent time period.

17. The method as claimed in claim 6, wherein at least one subscriber terminal to which the incoming call is signaled is defined by the contents of another table which is stored in the switching center and is linked to the table which defines that subscriber group.

18. The method as claimed in claim 7, wherein the table which defines the subscriber group, and the another table linked thereto, are stored in a central database in the switching center.

19. The method as claimed in claim 8, wherein at least the call number of the at least one subscriber terminal to which the incoming call is signaled is entered in the another table.
