Abstract: A communications switching system such as a PBX, central office switch and the like, responds to an incoming call to a called party by signaling a paging device as well as some other communications device having communications capability different from that of the paging device. In the disclosed embodiment, which pertains to a private branch exchange (PBX), this other communications device is one which provides two-way voice communications. Advantageously, the paging device may also be provided with the capability of signalling the communications system that the called party will shortly answer the call via a communications device possessing two-way voice communications. Upon receipt of this pager-transmitted signal, the communications system, if desired, can be provided with the ability to provide an announcement to the calling party of the called party's intent to answer the call.

Abstract: A radio telephone includes a cordless telephone fixed set and a mobile set. The cordless telephone fixed set is connected to a telephone line. The mobile set includes a first transmitter and a first receiver for radio communication with the cordless telephone fixed set. In addition, the mobile set includes a second transmitter and a second receiver for radio communication with an external base station. The mobile set includes a device for instructing a communication start, a device for detecting an answer signal outputted from the cordless telephone fixed set, a device for enabling the first transmitter to transmit a talking start signal when the instructing device instructs the communication start, and a device for, in cases where the first transmitter transmits the talking start signal but the detecting device fails to detect the answer signal, enabling the second transmitter to transmit a talking start signal.

Abstract: A wireless telecommunications system where call path resources are allocated in an orderly manner by queuing call requests during, for example, radio channel unavailability, and assigning radio channels to queued call requests as they become available. To accomodate movement of the mobile station within the service area, a plurality of queues are provided for different locations and a call request is sequentially placed in different queues as the mobile station moves. The system is usable for both incoming and outgoing calls.
