Retained Data Handling at Differentiated Response Times

A method for handling response times in a communication system, the communication system comprising at least one data retention system having at least one storage space for retained data, wherein the at least one storage space has a defined response time for delivering retained data, the method comprising:

• receiving a request for retained data from an authorized organization to the at least one data retention system, the request comprising 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 time segment corresponding to one defined response time;
• delivering an acknowledge message from the at least one data retention system to the authorized organization, the acknowledge message comprising response and identification information corresponding to the at least one time segment.

A computer program product stored in a non-transitory computer readable medium for handling response times in a communication system, the communication system comprising at least one data retention system having at least one storage space for retained data, wherein the at least one storage space has a defined response time for delivering retained data, the computer program product comprising software instructions which, when run on one or more processing circuits, causes the one or more processing circuits to:

• receive a request for retained data from an authorized organization to the at least one data retention system, the request comprising a specified data type and a retention time range;
• divide, in the at least one data retention system, the received retention time range into at least one time segment, each time segment corresponding to one defined response time;
• deliver an acknowledge message from the at least one data retention system to the authorized organization, the acknowledge message comprising response and identification information corresponding to the at least one time segment.

A node of a communication system, the node implementing a Data Retention function, the communication system comprising at least one storage space for retained data, the at least one storage space having a defined response time for delivering retained data, the node comprising:

• a receiver configured to receive a request for retained data, the request comprising a specified data type and a retention time range;
• a processing circuit configured to divide the received retention time range into at least one time segment, each time segment corresponding to one defined response time;
• a transmitter configured to deliver an acknowledge message, the acknowledge message comprising response and identification information corresponding to the at least one time segment.

A node of a communication system, the node implementing an authorization function, the node comprising:

• a transmitter configured to send a request for retained data, the request comprising a specified data type and a retention time range;
• a receiver configured to receive an acknowledge message, the acknowledge message comprising response and identification information corresponding to a divided time segment.
