Abstract
A determination is made that an identity of a non-target communicating entity (102) with which a target communicating entity (101) is communicating, is to be obfuscated in any report of lawful interception of the target communicating entity (101) to a law enforcement agency (131). Lawful interception is performed of the target communicating entity (101) and information pertaining to the lawful interception of the target communicating entity (101) is reported to the law enforcement agency (131). The reported information comprises non-obfuscated identity information of the target communicating entity (101) and obfuscated identity information of the non-target communicating entity (102).
Claims9
A method of managing lawful interception, LI, information in a telecommunication network, the method comprising:
- receiving, by an LI administrative function, ADMF via an LI HI1 interface from a Law Enforcement Agency, LEA, an object configured to indicate that identity information of a non-target communicating entity is to be obfuscated in a report of LI of a target communicating entity to the LEA,
- receiving, by a mediation and delivery function, MDF2, from the ADMF, TaskDetails, comprising a data field configured to indicate that the identity information of the non-target communicating entity is to be obfuscated based on the object,
- based on the data field received from the ADMF, determining that the identify information of the non-target communicating entity, with which the target communicating entity is communicating, is to be obfuscated in the report of LI of the target communicating entity to the LEA,
- performing LI of the target communicating entity, and
- reporting information pertaining to the performed LI of the target communicating entity to the LEA, said reported information comprising non-obfuscated identity information of the target communicating entity and obfuscated identity information of the non-target communicating entity.
A computer system comprising a plurality of server blades, each server blade comprising a processor and a memory, said memory containing instructions executable by said processor whereby said computer system is operative to:
- receive, by an LI administrative function, ADMF via an LI HI1 interface from a Law Enforcement Agency, LEA, an object indicating that identity information of a non-target communicating entity is to be obfuscated in a report of LI of a target communicating entity to the LEA,
- receive, by a mediation and delivery function, MDF2, from the ADMF, TaskDetails, comprising a data field configured to indicate that the identity information of the non-target communicating entity is to be obfuscated based on the object,
- based on the data field received from the ADMF, determine that the identity information of the non-target communicating entity, with which the target communicating entity is communicating, is to be obfuscated in the report of LI of the target communicating entity to the LEA,
- perform LI of the target communicating entity, and
- report information pertaining to the performed LI of the target communicating entity to the LEA, said reported information comprising non-obfuscated identity information of the target communicating entity and obfuscated identity information of the non-target communicating entity.
