Abstract

A personal paging equipment is connected to a telephone private branch exchange having a central controller and a central memory, wireless call (ringing) device belonging to the personal paging equipment in addition to the paging transmitters, these call or ringing devices dependent on the selected operating mode of the personal paging equipment, providing the subscribers to be called either with only a ringing signal or, in addition to the ringing signal, the telephone number of the calling subscriber as well, for example, via an integrated display. When the page request derives from an exchange, the telephone number of the calling subscriber is replaced by an identifier information by the controller and is forwarded to the personal paging equipment. After selecting the identifier information at an arbitrary telephone set, the connection is through-connected between the waiting, calling subscriber and the answering subscriber.

Claims

1. A method for personal paging in a telephone private branch exchange comprising a central controller, a central memory, a personal paging device for selective communication with a plurality of call devices each assigned to a respective person to be paged, a plurality of external connection sets for connecting calls external of the telephone private branch exchange and a plurality of internal connection sets connected to subscriber telephone instruments of the telephone private branch exchange;

the personal paging device, in a predetermined operating mode of the type wherein calls originating in the telephone private branch exchange from one of the telephone instruments cause call information including the subscriber line number of the calling subscriber to be communicated to the personal paging device from the central controller, hence in addition to a call signalization the line number of the calling subscriber is reproduced;

at the call device in the case in which a calling subscriber is external of the private branch exchange and the line number of the calling subscriber is absent, the method for personal paging comprising the steps of;

generating a calling line identifier information in the central controller;

communicating said identifier information from the central controller to the personal paging device and reproducing said identifier information of the signaled call device;

storing data in the central memory for designating the external connection set of the calling subscriber and the subscriber line of the called subscriber in allocation thereto;

transmitting an acknowledgment to the external connection set of the calling subscriber to indicate to the calling subscriber that the exchange has received the page requested and to hold the line; and

receiving the identifier information from an arbitrary subscriber telephone instrument causing the central controller to connect the internal connection set of the arbitrary subscriber telephone instrument to the external connection set of the calling subscriber.

2. The method of claim 1, and further comprising the steps of:

utilizing the identifier information to determine a reporting procedure;

inputting the identifier information by the called subscriber and the telephone number thereof at a telephone instrument of the exchange; and

accessing a table of the memory storing the data designating the external connection set of the calling subscriber in the reporting procedure and the line number of the call subscriber assigned thereto; and

outputting the access data to the central controller to cause the central controller to set up a connection between the called subscriber and the calling subscriber.
