Roaming is a service provided by Mobile Service Providers. Customers of a Home Service Provider may use the infrastructure of another, a Serving Service Provider (see figure 5) to give its customer the ability to make calls when outside the home service provider’ s territory. The goal is to have a customer receive the same service (or as close to the same service) when travelling in an area supported by another network as the customer receives when in their home service provider’s area. Please refer to [105] to see an example implementation with more detail.
