Abstract
The disclosed technology is directed towards intelligently steering a roaming mobile communications device to a roaming carrier that is preferred by the mobile device's home network. When a mobile device requests to connect to a first visited network, decision logic of the home network determines whether the first visited network is the preferred visited network. If not, the home network returns a steer message (via the first visited network) to steer the mobile device to a preferred visited network. In one implementation, the steering decision is performed at the network edge by a home security edge protection proxy (H-SEPP) node coupled to a visiting SEPP (V-SEPP) node, which reduces hops and latency. What the home network considers preferred can be changed (e.g., dynamically) as desired by the home network. Also described is service-based steering that selects a different visited network based on a particular service requested by a mobile device.
