A METHOD OF AND A DEVICE HANDLING CHARGING DATA IN AN IP-BASED NETWORK

摘要

The invention relates to a method of handling charging data in a first network entity of an IP-based network. The first network entity receives an IP communication control message comprising user identification data and an associated encryption key. Charging data associated with a communications activity related to said user identification data is encrypted using the encryption key and combined with the user identification data to obtain a charging record with encrypted charging data which charging record is transmitted to a second network entity having the role of charging gateway function. The second network entity receives the charging record with encrypted charging data and subjects the encrypted charging data to a decryption process to obtain a charging record comprising the user identification data and unencrypted charging data.
