Abstract
A method used in wireless communications for displaying an icon on a wireless communications device indicating that a calling party is a subscriber of a same wireless communications service provider of a called party. A terminating mobile station switching center (MSC) flags a routing number port associated with a routing number and returns the routing number to an originating MSC when it determines that a request for the routing number is sent from a home locator register (HLR) of the called party's wireless communications service provider and the calling party is also a subscriber of the called party's wireless communications service provider. When receiving an incoming call, the terminating MSC inspects whether the incoming call is to be sent through a flagged routing number port. If so, the terminating MSC generates a SETUP message with an instructions to display the icon. In responsive to the SETUP message, the wireless communications device of the called party displays the icon accordingly, indicating that the calling party is a subscriber of the same wireless communications service provider as the called party.
