Abstract

The present invention relates to methods and arrangements in a mobile telecommunication system to generate interception related information IRI, including geographical location of a monitored mobile subscriber/equipment. The system is configured to provide to an Intercept configuration unit ICU, information collected from an Intercept Access Point IAP; MSC. The system is also configured to proceed with a Network Induced Location Request NI-LR procedure, which method comprises the following steps: —Receiving to the Intercept Access Point from the Intercept configuration unit, a request to monitor the mobile subscriber/equipment, —Detecting in the Intercept Access Point of a specified Interception Related Information activity IRI involving the monitored subscriber/equipment, —The Intercept Access Point IAP; MSC initiates start of the Network Induced Location Request NI-LR procedure.

Claims

1. Method in a mobile telecommunication system to generate interception related information, including geographical location of a monitored mobile subscriber/equipment, which system is configured to provide to an Intercept configuration unit, information collected from an Intercept Access Point and which system is configured to proceed with a Network Induced Location Request procedure in case an emergency call is performed, which method comprises the following steps:

receiving to the Intercept Access Point from the Intercept configuration unit, a request to monitor the mobile subscriber/equipment;

detection in the Intercept Access Point of a specified Interception Related Information activity involving the monitored subscriber/equipment, characterized in that;

the Intercept Access Point initiates start of the Network Induced Location Request procedure, as if an emergency call had been performed.

2. Method in a mobile telecommunication system according to claim 1 whereby the Intercept configuration unit comprises a Law Enforcement Agency attached to an Administration Function, which method comprises the following further steps:

sending from the Law Enforcement Agency to the Administration Function, the request to monitor the mobile subscriber/equipment;

forwarding the request from the Administration Function to the Intercept Access Point.

3. Method in a mobile telecommunication system to generate interception related information according to claim 2, whereby Location estimate information is delivered from the Intercept Access Point to the Law Enforcement Agency.

4. Method in a mobile telecommunication system to generate interception related information according to claim 3, whereby the location estimate information is added to the Interception Related Information related to the detected activity before the delivering from the Intercept Access Point to the Law Enforcement Agency.

5. Method in a mobile telecommunication system to generate interception related information according to claim 1, which system comprises a Gateway Mobile Location Center associated to the Intercept Access Point which method comprises the following further steps:

delivering of the location estimate from the Intercept Access Point to the Gateway Mobile Location Center.

6. Method in a mobile telecommunication system to generate interception related information according to claim 1, which method comprises the following further step:

sending from the Intercept configuration unit to the Intercept Access Point, a specification of at least one Interception Related Information activity that will initiate start of the Network Induced Location Request procedure.

7. Method in a mobile telecommunications system according to claim 1, which telecommunication system is a GSM or an UMTS network.

8. Arrangement in a mobile telecommunication system to generate interception related information, including geographical location of a monitored mobile subscriber/equipment, which system is configured to provide to an Intercept configuration unit, information collected from an Intercept Access Point and which system is configured to proceed with a Network Induced Location Request procedure in case an emergency call is performed, which arrangement comprises:

means for receiving to the Intercept Access Point from the Intercept configuration unit, a request to monitor the mobile subscriber/equipment;

means for detecting in the Intercept Access Point of a specified Interception Related Information activity involving the monitored subscriber/equipment, characterized in;

means in the Intercept Access Point for initiating start of the Network Induced Location Request procedure, as if an emergency call had been performed.

9. Arrangement in a mobile telecommunication system according to claim 8 which Intercept configuration unit comprises a Law Enforcement Agency attached to an Administration Function and which arrangement further comprises:

means for sending from the Law Enforcement Agency to the Administration Function, the request to monitor the mobile subscriber/equipment;

means for forwarding the request from the Administration Function to the Intercept Access Point.

10. Arrangement in a mobile telecommunication system to generate interception related information according to claim 9, which comprises means to deliver Location estimate information from the Intercept Access Point to the Law Enforcement Agency.

11. Arrangement in a mobile telecommunication system to generate interception related information according to claim 10, which comprises means to add location estimate information to the Interception Related Information related to the detected activity before the delivering from the Intercept Access Point to the Law Enforcement Agency.

12. Arrangement in a mobile telecommunication system to generate interception related information according to claim 8, which system comprises a Gateway Mobile Location Center associated to the Intercept Access Point which arrangement further comprises:

means for delivering the location estimate from the Intercept Access Point to the Gateway Mobile Location Center.

13. Arrangement in a mobile telecommunication system to generate interception related information according to claim 8, which arrangement further comprises:

means for sending from the Intercept configuration unit to the Intercept Access Point, a specification of at least one Interception Related Information activity that will initiate start of the Network Induced Location Request procedure.
