ARRANGEMENT AT A MOBILE DATA UNIT

摘要

The invention is based on a platform that has both hardware and software. The latter includes, amongst other things, an algorithm to solve the problem encountered when, on passing between countries and operators, data services have to roam between mobile networks. The invention handles and solves existing technical limitations such as existing roaming logic for switches between operators not taking into account: which services the ‘original’ operator has activated; geographical coverage; different costs for different services; and, whether services other than speech can function in the selected network.

主权项

1. A method for implementing roaming between mobile telephone networks, the method comprising:
implementing the roaming method locally in a mobile unit; searching for available mobile telephone networks; choosing a mobile telephone network based on a number of parameters selected from the group consisting of available services, tariffs, coverage, and priority parameters; wherein the method comprises a self-learning part that, if the mobile unit fails to connect to the mobile telephone network or to set up a session, adjusts a priority parameter of the mobile telephone network downwards, by altering the weighting.
