Definitions

  • This invention relates generally to the field of communication systems and in particular to a cordless telephone communication system.
  • cordless telephone systems include cordless telephones which operate with private base stations at users' homes, offices or other locations which are connected to a public switching telephone network (PSTN). Each private base station is typically meant to be used by one subscriber.
  • the next generation of cordless telephone systems (called CT-2 systems, for cordless telephone-2) include cordless telephones which operate with plurality of public base stations (located at a n umber of remote telepoints). In CT-2 systems, the cordless telephones may also operate with the private base stations.
  • the communication between the cordless telephone and the PSTN may be established once the subscriber is within range of a public base station which are generally scattered throughout a coverage area.
  • the subscriber when in range, may remotely place a call through the public base stations without the inconveniences associated with using present public telephone booths. Placing such a call will not present much difficulty, but receiving calls through public base stations will present some problems because the subscriber unit may not be located within the access range of the public base stations at any given time. Therefore, the cordless telephones may also operate as a paging receiver for paging the subscriber.
  • the present invention addresses the desirability of providing the subscriber with office services such as facsimilies, etc., at the remote telepoints which are generally available in an office environment.
  • a communication system which includes cordless telephones which communicate with a telephone network through a plurality of public base stations located at remote points.
  • the public base station include means for providing a wireless communication with the cordless telephones.
  • the public base station includes a message center having message transfer accessory devices for transfemng and retrieving information, image, or voice accessory messages.
  • FIG. 1 illustrates block diagram of communication system of the present invention.
  • Figure 2 illustrates a block diagram of a public base station according to the present invention.
  • FIG. 3 illustrates block diagram of cordless telephone according to the present invention.
  • Figure 4 illustrates operation flow chart of communication system of Figure 1 according to the present invention. Detailed Description of the Preferred Embodiment
