Abstract

A call routing system includes an authorization and call routing equipment (ACRE) 117, a cordless base station 115 connected by a wireline network 111 having caller identification. The cordless base station 115 initiates a call to the ACRE 117, which receives the cordless base station'"'"'s 115 telephone number. The ACRE 117 then uses the telephone number for routing subsequent telephone calls to the cordless base station 115. The cordless base station 115 can receive and store caller indentification information and transmit this information to a radiotelephone 101.

Claims

1. Call routing equipment for use in a communication system including a base station having an assigned landline telephone number and a base identification number (BID), communicatively coupled with the call routing equipment via a public switched telephone network (TELCO), and capable of sending the assigned landline telephone number and BID to the call routing equipment, the call routing equipment capable of storing landline telephone numbers and BIDs in the call routing equipment, the call routing equipment comprising:

means for receiving the assigned landline telephone number and the BID from the base station via the TELCO providing caller identification;

means for finding a stored landline telephone number for the base station according to the received BID;

means for determining if the received assigned landline telephone number is equal to the stored landline telephone number for the base station; and

means for updating the stored landline telephone number for the base station with the received assigned landline telephone number when the received assigned landline telephone number is not equal to the stored landline telephone number of the base station.

2. A method of updating a base station'"'"'s stored landline telephone number that is stored in a call routing equipment in preparation for future call routing, the base station having an assigned landline telephone number and a base identification number (BID) and being communicatively coupled with the call routing equipment via a public switched telephone network (TELCO), the TELCO providing caller identification, the method comprising the steps of:

initiating, by the base station, a call to the call routing equipment;

receiving, by the call routing equipment, the BID sent from the base station;

receiving, by the call routing equipment, the assigned landline telephone number from the TELCO via caller identification;

determining, by the call routing equipment, if the assigned landline telephone number is equal to the stored base station'"'"'s landline telephone number; and

updating, by the call routing equipment, the stored base station'"'"'s landline telephone number with the assigned landline telephone number when the assigned landline telephone number is not equal to the stored base station'"'"'s landline telephone number.
