Method and apparatus for reserving a telephone line in a telepoint communication system
First Claim
1. A method for coupling a cordless telephone second generation (CT-2) telepoint communication unit (TCU) to a CT-2 telepoint base station (TBS), wherein the CT-2 TBS is coupled to a public switched telephone network (PSTN) via a limited number of telephone lines, the method comprising the steps of:
- a) generating and transmitting a signal from the TCU in response to user input;
b) receiving at the TBS the signal and determining whether the signal is a call request or a telephone line reservation request; and
c) in response to receiving and determining the signal is a telephone line reservation request by the TBS, reserving at least one of the limited number of telephone lines, thereby providing the TCU exclusive use of the at least one of the limited number of telephone lines for incoming calls to the TCU.

Abstract
A telepoint communication system 100 where the telepoint communication unit (TCU) 125 reserves a communication channel on the communication link 126, where the communication link 126 couples the telepoint base station (TBS) 110 to the public switched telephone network (PSTN) 105. Reserving the communication channel is accomplished by communicating information packets 130,133,136,140,143 and 146 between the TCU 125 and the TBS 110. Reserving the communication channel enables the TCU 125 to ensure the reserved communication is available to route incoming calls received on the telepoint communication system 100 to the TCU 125, particularly when an incoming call is expected.

9. A telepoint base station (TBS) coupled to a public switched telephone network (PSTN) via a limited number of telephone lines of the PSTN for coupling to a telepoint communication unit (TCU), the TBS comprising:
-
a transceiver for communicating with the TCU; and a controller, coupled to the transceiver and coupled to the limited number of telephone lines, for receiving a signal from the TCU, for determining whether the received signal is a call request or a telephone line reservation request, and, in response to determining the signal is a telephone line reservation request, for reserving one of the limited number of telephone lines as a reserved telephone line, thereby providing the TCU with exclusive use of the reserved telephone line for incoming calls to the TCU.

10. A telepoint communication unit (TCU) for coupling to a telepoint base station (TBS), wherein the TBS is coupled to a public switched telephone network (PSTN) via a limited number of telephone lines, the TCU comprising:
-
a key pad for a user to input a reservation service request or a call request; a transceiver for communicating with the TBS; and a controller, coupled to the key pad and the transceiver, for determining whether a call request or a reservation service request is received from the key pad and for transmitting a telephone line reservation request to the TBS via the transceiver in response to determining a reservation service request has been received from the key pad, thereby providing the TCU exclusive use of a reserved telephone line for incoming calls to the TCU, and for executing a call originating process in response to determining a call request has been received from the key pad. - View Dependent Claims (11)
