Abstract
Technology is disclosed herein for WPS call handling for at a roaming or non-WPS supported locations. In an implementation, a wireless network receives a SIP invite for user device from a roaming RAN of a visited network. The user device is subscribed to the wireless network and is authorized for WPS service by the wireless network. The IMS core of the wireless network sends a request to the subscriber management function of the network for a user profile for the user device including the PLMN of the roaming RAN. The subscriber management function identifies a user profile from multiple user profiles for the user device based on the PLMN. Each of the multiple user profiles corresponds to a PLMN category of multiple PLMN categories. The session manager of the wireless network sends a request to establish a default bearer to the roaming RAN based on the user profile.
