METHODS AND NETWORK NODES FOR CONTROLLING USAGE OF CACHING IN A TELECOMMUNICATIONS SYSTEM

摘要

The exemplary embodiments relate to a method for use in RAN node (700); a RAN node (700); a method for use in a CN node (800), and a CN node (800), for controlling usage of caching in the RAN on subscriber level. According to the present embodiments, the CN node (800) is configured to transmit to the RAN node (700) a signaling message including information on subscriber profile. The RAN node receives and analyses the message to determine whether an indicator is provided in the message. The RAN node (700) further determines in the case the indicator is present in the message whether or not caching in the RAN is allowed for use by the subscriber, and to control usage of caching in the RAN based on the result of the determination.
