The data notification message may comprise an identifier of a packet data unit session of the wireless device. The data notification message may comprise a subscriber permanent identifier. A buffering duration may be determined for the wireless device in response to the wireless device being unreachable. The access and mobility management function may send a data buffering request message to the session management function. The data buffering request message may comprise a request to buffer the data for the buffering duration.
