Techniques for archiving data exchanged between a terminal and a wireless communication network during a session are described. Session data may be archived at a network entity in real-time while the session is in progress or may be uploaded to the network entity for archival after the session has terminated. The network entity may archive all data exchanged during the session or only data of the terminal, depending on whether authorization is received from other terminals in the session. The network entity may assign an identifier for the session and may store the identifier and other attributes for the session. During or after the session, the network entity may receive from the terminal a request for all or a portion of the archived data and would then provide the requested data. The network entity may archive a single copy of the session data for all terminals in the session.
