Abstract
Techniques are described herein for implementing a presence application server to handle Universal Profile (UP) transfers over roaming. The presence application server may receive a Session Initiation Protocol (SIP) request from a user device. The SIP request can include presence information of the user device, P-Access-Network-Info (PANI), and a subscriber identifier of a subscriber associated with the user device. Based at least on the presence information, the presence application server can determine whether the user device is UP capable. Additionally, the presence application server can determine whether the user device is roaming based at least on the PANI. If the user device is roaming, the presence application server can indicate that the user device is roaming and remove a tuple associated with the presence information indicating the UP capabilities of the user device in a SIP response. Removing the tuple suspends the user device's UP capabilities.
