Patent ID: 8364145

Claim:
A method for altering man machine interface (MMI) configurations for use in a device, comprising: determining whether a first location information received from a first cell broadcast system resident on a currently associated network is different from a second location information stored in a volatile or non-volatile storage device, or whether a first network information received from the first cell broadcast system resident on the currently associated network is different from a second network information stored in the volatile or non-volatile storage device, wherein the first location information indicates a geographic area where the first cell broadcast system situates, the first network information indicates a first network operator providing communication services of the currently associated network, the second location information or the second network information is received from a second cell broadcast system resident on a previously associated network, the second location information indicates a geographic area where the second cell broadcast system situates, and the second network information indicates a second network operator providing communication services of the previously associated network; querying a status of a supplementary service (SS by issuing a supplementary service (SS) interrogation request to a currently associated network when the first location information is different from the second location information or the first network information is different from the second network information, wherein the SS modifies or supplements a basic telecommunication service; acquiring the queried status carried by a SS interrogation response from the currently associated network; enabling a menu item of a service menu when the queried status indicates that the service is available; and disabling the menu item of the service menu or removing the menu item from the service menu when the queried status indicates that the service is unavailable, preventing a user from requesting the service via the menu item.
