Abstract: The present invention relates to a method for handling response times in a communication system comprising at least one data retention system having at least one storage space for retained data. The at least one storage space has a defined response time (high, medium, low) for delivering retained data. The method comprises the following steps: —Receiving a request for retained data from an authorized organization to the at least one data retention system, which request comprises a specified data type and a retention time range —Dividing in the at least one data retention system, the received retention time range into at least one time segment each corresponding to one defined response time —Delivering an acknowledge message from the at least one data retention system to the authorized organization, which message comprises response and identification information corresponding to the at least one divided time segment.

Abstract: A method and apparatus for handling a data object accessible by more than one node. A server in a communication network stores information relating to the data object stored at a first node. The server then receives a subscription request message from a second node. This subscription request message subscribes to updates relating to the data object stored at the first node. A copy of the data object is accessible by the second node. The server subsequently receives a publication message relating to a change to the data object stored at the first node and which indicates an identity of the data object and an indication of the changes. The server sends a notification message relating to the change to the data object towards the second node, which is usable by the second node to make corresponding changes to the copy of the data object accessible by the second node.

Abstract: The present invention relates to a method for handling response times in a communication system comprising at least one data retention system (2;2,22,23) having at least one storage space (6A, 6B, 6C) for retained data. The at least one storage space (6A, 6B, 6C) has a defined response time (high, medium, low) for delivering retained data. The method comprises the following steps:—Receiving (31) a request for retained data from an authorized organization (3) to the at least one data retention system (2;2,22,23), which request comprises a specified data type and a retention time range—Dividing (37) in the at least one data retention system, the received retention time range into a least one time segment each corresponding to one defined response time (high, medium, low).—Delivering (32) an acknowledge message from the at least one data retention system to the authorized organization, which message comprises response and identification information corresponding to the at least one divided time segment.

Abstract: The present invention relates to a method for supervising log activities in a Communication Service Provider's domain (CSP) comprising a monitoring system (DR, LI) and a Log System. The method comprises steps of sending a request for log activities and receiving a result via standard defined interfaces (HIXA, HIXB, HIA, HIB; HIX1, HIX2, HI1, HI2) between a public authority (RA, LEMF) and the Provider's domain (CSP).

Abstract: A method is proposed for managing requests from Law Enforcement Agencies for interception or retention of data relating to a target user. The method detects a request of interception or retention on the target user and verifies whether an electronic warrant is activated with respect to the user.

Abstract: A telecommunications network having at least one Data Retention Source and a Data Retention system adapted to communicate with the Data Retention Source and with a lawful requesting authority. The Data Retention Source is configured as a Diameter client and the Data Retention system is configured as a Diameter server. The Data Retention Source comprises means for generating at least one report containing data related to a communication session and means for sending such report to the Data Retention system as a Diameter message using a Data Retention Diameter application protocol.

Abstract: The invention relates to a method of providing call- or service-related information to a Lawful Interception (LI) system or to a Data Retention (DR) system in a telecommunications network. In the method, a node is provided, which is in communication with an interception requesting element of the LI/DR system. At the node, a record relating to a communication involving a target user is generated and finally sent to the interception requesting element. Before sending the record, at the node it is checked whether a unique reference univocally identifying the communication involving the target user is already available to the node and, if not, such unique reference is generated by the node. Finally, the unique reference is included in the record, which can then be sent to the interception requesting element.
