Abstract

A fixed wireless communication system (100) comprises a wireless subsystem and a backbone network. The wireless subsystem includes at least one base transceiver site (104, 105) and at least one stationary remote unit (107, 108). The stationary remote unit communicates with the base transceiver site via a wireless communication resource (110, 111). The wireless subsystem resides in a first geographic area (155) served by a first public switched telephone network (PSTN) access switch (129). The backbone network includes at least one point of presence (POP, 120-123) and a switch (125). The switch serves to at least route voice communications between the stationary remote unit and a PSTN subscriber unit (139) residing in a second geographic area (157) served by a second PSTN access switch (135). The POPs couple the switch to at least the wireless subsystem, the first PSTN access switch, and the second PSTN access switch. The switch employs a method to facilitate communication between a wireless subsystem subscriber (101, 102) and either a PSTN subscriber (133, 139) or another wireless subsystem subscriber, wherein a switching path is established to include a PSTN access switch only in the event that received call set-up information indicates that the communication involves a PSTN subscriber.
