Method for mobile phone numbers aliasing for roaming users

Disclosed is a method for mobile phone numbers aliasing for roaming users. Benefits include improved functionality and improved performance.

Background

              Conventionally, the costs of roaming calls are high, and for international roaming are sometimes extremely high. In some countries, they may be as high as few dollars per minute. For example, in the global system for mobile communication (GSM), two users can be in the same country but their mobile phones enter international roaming mode. When one user calls another, they pay the price of two international calls even if they call from one room to another.

 

              When two mobile phones from the same home network are in roaming mode and call each other, the caller sets up a connection between the roaming network and the home network. The home network sets up a connection between the home network and the roaming network. This arrangement is very cost ineffective (see Figure 1).

General description

              The disclosed method is mobile phone number aliasing for roaming users. The method decreases the cost of roaming calls by assigning a temporary alternate (alias) phone number on the network being visited for the connection.

Advantages

              The disclosed method provides advantages, including:

•             Improved functionality due to providing alias network numbers to lower the cost of roaming calls

•             Improved performance due to simplifying the call route by making the call local to the visited network

Detailed description

              The disclosed method adds to the GSM or any similar standard network a small extension that enables users to lower the cost of roaming calls. A network operator creates a pool of home number aliases. A numbers from this pool is assigned when a mobile phone logs in as a visitor (enters the roaming session). From this moment, the mobile phone can be reached using the alias number or its home network number. Users from the network that issued the alias can call the mobile phone for a cheaper rate. For local calls, the calling line identit...
