The plurality of PLP's may contain a second signaling information and a third signaling information, and the third signaling information can be transmitted through a specific PLP among a plurality of PLP's.

Two different types of signaling channels are used to communicate signaling information to a user equipment terminal in a radio communications system.

Each ground station, in turn, is dedicated a separate burst of information for transmitting only signaling information back to the master signaling station.

The signaling information is obtaining via a communication link connecting the PBX and the server.

A shared signaling channel is established between a radio access network and the multiple user equipment terminals to transmit substantive signaling information relevant to a data channel.
