An integrated telecommunications system includes a wired subsystem consisting of wired links for establishing communication with terminals connected thereto, a wireless subsystem consisting of a group of base stations for communicating over wireless links, and a common central switch for establishing interconnections between selected communications channels. A switching controller is connected to the central switch for controlling the establishment of interconnections between selected communication channels in the system. A group controller is connected to the central switch for ensuring message-based mobility management of the wireless subsystem independently of the first controller.

A PBX-based integrated telecommunications system comprising: a) a wired subsystem comprising wired links for establishing communication with wired terminals connected thereto; b) a wireless subsystem comprising a group of base stations for communicating over wireless links to mobile terminals; c) a common central switch for establishing interconnections between selected communications channels and connected to said wired terminals and said base stations; d) a switching controller connected to said central switch for controlling the establishment of interconnections between selected communications channels in said system; e) a common group controller connected to said base stations through said central switch for exchanging control packets over a data link layer with said mobile terminals through said base stations to control said mobile terminals and thereby provide message-based mobility management of said wireless subsystem independently of said switching controller; and f) said base stations acting as multiplexers and forming a transparent encapsulation bridge connecting said data link layer between the mobile terminals and said group controller to permit the exchange of said control messages therebetween, said group controller further comprising means for sending and receiving control packets over said wireless links, means for monitoring the operation of each channel in said wireless links responsive to received control packets, and means for generating said control packets for transmission over said wireless subsystem to control the operation thereof.
