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. ## Claims ### Claim at position 1 1-16. (canceled) ### Claim 17 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. ### Claim 18 (depends on 17) The method for handling response times of claim 17, wherein the delivering the acknowledge message comprises delivering the acknowledge message through a Handover Interface A (HIA). ### Claim 19 (depends on 17) The method for handling response times of claim 17, further comprising delivering, from the at least one data retention system to the authorized organization, requested data related to an identified time segment. ### Claim 20 (depends on 17) The method for handling response times of claim 17, further comprising: sending a getstatus request message from the authorized organization to the at least one data retention system, the getstatus message comprising a request for data delivery status of an identified time segment; sending a status reply message from the at least one data retention system to the authorized organization, the status reply message comprising the requested data delivery status of the identified time segment. ### Claim 21 (depends on 20) The method for handling response times of claim 20, further comprising: receiving the status reply message at the authorized organization, the status reply message indicating that data related to the identified time segment is ready to be delivered; sending a getresult message from the authorized organization to the at least one data retention system, the getresult message comprising a request for retained data related to the identified time segment; sending a second status reply message from the at least one data retention system to the authorized organization, the second reply message comprising the requested retained data related to the identified time segment. ### Claim 22 (depends on 20) The method for handling response times of claim 20, wherein the getstatus request message is delivered through the Handover Interface A (HIA). ### Claim 23 (depends on 17) The method for handling response times of claim 17, wherein storage differentiation in the at least one storage space is based on type of service. ### Claim 24 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. ### Claim 25 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. ### Claim 26 (depends on 25) The node of claim 25, wherein the transmitter is configured to deliver the acknowledge message through a Handover Interface A (HIA). ### Claim 27 (depends on 25) The node of claim 25, wherein the receiver is configured to receive a getstatus request message comprising a request for delivery status. ### Claim 28 (depends on 27) The of claim 27, wherein the getstatus request message is received through a Handover Interface A (HIA). ### Claim 29 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. ### Claim 30 (depends on 29) The node of claim 29, wherein the receiver is configured to receive the acknowledge message through a Handover Interface A (HIA). ### Claim 31 (depends on 29) The node of claim 29, wherein the transmitter is configured to send a getstatus request message comprising a request for delivery status. ### Claim 32 (depends on 31) The node of claim 31, wherein transmitter is configured to send the getstatus request message through a Handover Interface A (HIA).
