Equal access to inter-exchange carriers in a mobile wireless packet data communication system
First Claim
1. A mobile wireless packet data communication system for communicating in a connectionless manner comprising:
- a mobile wireless end system, having a fixed home area, for sending and receiving data in a connectionless manner and which allows a subscriber to specify a preferred inter-exchange carrier for carrying data to and from said mobile wireless end system during a particular session;
a serving mobile data intermediate system for receiving from said mobile wireless end system information identifying said preferred inter-exchange system and for sending information identifying said preferred inter-exchange carrier to a home mobile data intermediate system associated with said mobile wireless end system;
a home mobile data intermediate system, which must be accessed before the subscriber is permitted to use services provided by said communication system, where said home mobile data intermediate system confirms the subscriber'"'"'s preferred inter-exchange carrier for the particular session to the serving mobile data intermediate system; and
a plurality of inter-exchange carriers for transmitting data in a connectionless manner between components of said communication system,where the serving mobile data intermediate system routes reverse traffic during the particular session via said preferred inter-exchange carrier;
and where the home mobile data intermediate system routes forward traffic during the particular session via said preferred inter-exchange carrier if the mobile wireless end system is located outside its fixed home area.

Abstract
The present invention discloses an improvement to a wireless packet data communication system by permitting a subscriber using a mobile end system (M-ES) to select the inter-exchange carrier (IXC) which will carry the data over those network paths for which the subscriber bears the cost during a particular communication session. The present invention allows the subscriber to specify a preferred inter-exchange carrier in an optional preferred IXC field added to an end system hello message. During registration and authorization procedures, an identifier corresponding to the preferred inter-exchange carrier is transmitted between a serving mobile data intermediate system (MD-IS) and a home MD-IS in a preferred IXC field added to standard registration protocol messages. If the subscriber has specified a preferred inter-exchange carrier in the preferred IXC field, then this preferred inter-exchange carrier is given higher priority than a default preferred inter-exchange carrier selected when the user subscribes to the network services. Each MD-IS is provided with a new database that maps inter-exchange carrier identifiers to a corresponding boundary router address associated with the preferred inter-exchange carrier in order to route data packets via the subscriber'"'"'s preferred IXC. The present invention thus allows data to be sent over the subscriber'"'"'s preferred inter-exchange carrier on paths in both the forward and reverse directions on a per session basis.

16. A method of providing equal access to inter-exchange carriers in a mobile wireless packet data communication system for communicating in a connectionless manner, said method comprising the steps of:
-
specifying a preferred inter-exchange carrier for carrying data to and from a mobile wireless end system in a connectionless manner during a particular session; sending information identifying said preferred inter-exchange carrier from said mobile wireless end system to a serving mobile data intermediate system, during a registration procedure for said mobile wireless end system; sending information identifying said preferred inter-exchange carrier from said serving mobile data intermediate system to a home mobile data intermediate system during said registration procedure; and sending information confirming said preferred inter-exchange carrier from said home mobile data intermediate system to said serving mobile data intermediate system during said registration procedure. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
