Abstract

The invocation of an intelligent network service in a call handler for calls being routed to mobile stations in a mobile communication network is done in such a way that if a call being handled is a call to be routed to a mobile station, and if it is determined that at least one intelligent network identifier is activated for that mobile station a further comparison of a stored condition parameter of the mobile station with a current value of that mobile station'"'"'s condition parameter is performed, and where the decision regarding the invocation of an intelligent network service depends on the outcome of such a comparison.

Claims

1. A method of controlling the invocation of an intelligent network service in a mobile telecommunications network, wherein said mobile telecommunications network includes a call handler for processing a call connection request to and from a mobile station wherein said call connection request includes call destination information and wherein said call handler is operable to determine routing information for said call connection request by interrogating a database associated with said call handler and an intelligent network service handler for processing interrogations requested by said call handler, wherein said database stores an intelligent network (IN) identifier indicating whether said mobile station has IN service activated, comprising the steps of:

storing a condition parameter for a destination mobile station identified by said call destination information;

checking by said call handler if said intelligent network identifier is activated in the database for a particular call connection request;

determining by said call handler, in response to said intelligent network identifier being activated, a particular condition of said destination mobile station, said step further comprising;

comparing said determined condition with said stored condition parameter by said call handler; and

in response to said comparison being satisfied, invoking a particular IN service by transmitting a signal from said call handler to said intelligent network service handler;

otherwise,

routing said call connection request without communicating with said intelligent network service handler and not invoking an IN service;

otherwise

routing said call connection request, in response to said intelligent network identifier not being activated, without communicating with said intelligent network service handler and not invoking an IN service.

2. The method of claim 1 wherein said stored condition parameter is an operating condition.

3. The method of claim 2 wherein said operation condition includes the operating status of said destination mobile station wherein said operation status further includes on/off status and busy/idle status.

4. The method of claim 1 wherein said stored condition parameter is a circumstantial condition.

5. The method of claim 4 wherein said circumstantial condition is the location of said destination mobile station.

6. The method of claim 5 wherein said location is a cell indicator.

7. The method of claim 5 wherein said location is a network indicator.

8. The method of claim 4 wherein said circumstantial condition is the current time associated with said destination mobile station.

9. The method of claim 1 wherein said call handler includes a mobile switching center (MSC) and said database includes a home location register (HLR) storing said routing information.

10. The method of claim 9 wherein said intelligent network service handler includes a service switching function and a service control function.

11. A call handler for controlling the invocation of an intelligent network service in a mobile telecommunications network and for processing a call connection request to and from a mobile station wherein said call connection request includes call destination information and wherein said call handler is operable to determine routing information for said call connection request by interrogating a database associated with said call handler and wherein said interrogation is received and processed by an intelligent network service handler, wherein said database stores intelligent network (IN) identifier indicating whether said mobile station has IN service activated, comprising:

means for storing a condition parameter for a destination mobile station identified by said call destination information;

means for checking if one or more intelligent network identifiers are activated in the database for a particular call connection request;

in response to an affirmative determination that said one or more intelligent network identifiers are activated for said call connection request;

means for determining, in response to said intelligent network identifier being activated, a particular condition of said destination mobile station;

means for comparing said determined condition with said stored condition parameter; and

in response to said comparison being satisfied, means for invoking a particular IN service by transmitting a signal to said intelligent network service handler;

otherwise,

means for routing said call connection request without communicating with said intelligent network service handler and not invoking an IN service;

otherwise, in response to a negative determination that said one or more intelligent network identifiers are not activated for said call connection request;

means for muting said call connection request without communicating with said intelligent network service handler and not invoking an IN service.

12. The call handler of claim 11 wherein said stored condition parameter is an operating condition.

13. The call handler claim 12 wherein said operation condition includes the operating status of said destination mobile station wherein said operation status further includes on/off status and busy/idle status.

14. The call handler of claim 11 wherein said stored condition parameter is a circumstantial condition.

15. The call handler of claim 14 wherein said circumstantial condition is the location of said destination mobile station.

16. The call handler of claim 15 wherein said location is a cell indicator.

17. The call handler of claim 15 wherein said location is a network indicator.

18. The call handler of claim 14 wherein said circumstantial condition is the current time associated with said destination mobile station.

19. The call handler of claim 11 comprises a mobile switching center (MSC) for receiving said call connection request and a home location register (HLR) for storing said routing information.

20. The call handler of claim 19 wherein said intelligent network service handler includes a service switching function and a service control function.
