A local exchange with limited access to outside communication systems is coupled to a global satellite communication system by a mobile exchange unit. The mobile exchange unit (MXU) provides access to the local exchange by relating one channel in the global communication system to many possible destinations in the local exchange. Multiple circuits of the local exchange are associated with a single mobile number. A gateway associated with the MXU associates an available radio channel with the calling subscriber. Multi-stage dialing is eliminated and a subscriber can directly dial a number of a party in the local exchange.

A method of providing an interface between a communication system and a local exchange, said interface including a mobile exchange unit (MXU), said method comprising the steps of: (a) translating a called number to identify a user associated with said local exchange; (b) requesting routing information to a destination gateway (DGW), said DGW being associated with said MXU; (c) choosing by said DGW, an identifier for said called number, said identifier identifying a radio channel coupling said MXU with said communication system; (d) signaling said MXU by identifying said user associated with said local exchange; (e) assigning said radio channel; and (f) establishing a connection to said local exchange using said called number, wherein step (a) further comprises the steps of: (a1) translating said called number at an originating gateway mobile switching center (OGMSC) to arrive at an initial address message (IAM), said IAM identifying said called number as said user associated with said DGW; (a2) translating said called number by said OGMSC to yield a first point code which identifies said DGW; (a3) sending said IAM to a mobile switching center (MSC) associated with said DGW; (a4) identifying by said MSC said called number as being associated with said local exchange by using said IAM; and (a5) translating said called number by said MSC to yield a second point code which identifies an earth terminal controller (ETC) associated with said local exchange.
