Title: USER PROFILE CONVERSION TO SUPPORT ROAMING INSIDE A DIAMETER NETWORK
Abstract:
In an example embodiment, a method includes receiving, from a visited network having a first wireless network type, a first update location request message according to a first signaling protocol, the first message associated with a user equipment roaming at the visited network. The first message is converted to a second update location request message according to a second signaling protocol and transmitted to a home network associated with the user equipment, the home network having a second wireless network type. An update location response message according to the second protocol is received from the home network, the update location response message including a user profile associated with the second network type. A combined user profile is generated based on a user profile associated with the first network type and the user profile associated with the second network type. The combined user profile is transmitted to the visited network in an update location answer message according to the first protocol.
