Description
TITLE OF THE INVENTION
2 "Registration of a New Cordless Telephone to an Existing System"
4 The present invention relates generally to cordless telephone systems S which are connected to a switched telephone network and, in particular, to 6 registration of a new cordless telephone to an existing cordless telephone 7 system.
8 Cordless telephone systems comprise an access unit which is 9 connected through a subscriber loop to a switched telephone network and 0 a plurality of cordless telephones. A two-way radio channel is established l l between the access unit and each cordless telephone by transmitting the l 2 system identification number of the system from a transmit end and l 3 verifying at a receive end that the transmitted system identification l 4 number is identical to that of the own system. This verification operation l S is necessary to avoid interference which might occur between cordless l 6 telephone systems which cover adjacent service areas. A system l 7 identification number is assigned to each system at the shipment from the l 8 factory by storing such number into the read-only memory of the access l 9 unit and into the read-only memory of each of the associated cordless 2 0 telephones. When a new cordless telephone is to be added to an existing 2 l system, the new telephone must be provided with a read-only memory in 2 2 which the same system identification number is stored. Such read-only 23 memories are currently prepared by the manufacturer in advance for 24 future system expansion or prepared by a servicing company on a per 2 5 demand basis. This adds to the total manufacturing cost of the system.
SllMMARY OF THE INVENTION
2 It is therefore an object of the present invention to reduce the total 3 manufacturing cost of a cordless telephone system by eliminating the need 4 to prepare a read-only memory for future system expansion. The present S invention is based on the utilization of a product identification, or "serial"
6 number which is uniquely assigned to each cordless telephone at the stage 7 of manufacture and the utilization of a memory of the type which allows 8 data to be electrically written and permanently stored. A typical example 9 of such a memory is the electrically erasable programmable read-only 10 memory, or EEPROM. In accordance with this invention, a new cordless 11 telephone is registered to an existing cordless telephone system by 12 transmitting the product identification number of the new cordless 13 telephone from the access unit of the system to the new cordless telephone, 14 receiving the transmitted product identification number at the new 15 cordless telephone and verifying that the transmitted product 16 identification number is correctly received. In response to the verification, 17 the system and telephone identification numbers of the new cordless 18 telephone are transmitted from the access unit and to the new cordless l 9 telephone and permanently stored into a memory of this telephone to be 20 used for establishing calls. Alternatively, the product and telephone 21 identification numbers of the new cordless telephone are transmitted from 2 2 one of the existing cordless telephones to the access unit to be relayed to 2 3 the new cordless telephone. This alternative approach eliminates the need 2 4 to visit the site of the access unit by a servicing personnel by remotely 25 controlling the access unit with the information transmitted from the 2 6 existing cordless telephone.

12~ 4 BRIEF DESCRIPTION OF THE DRAWINGS
2 The present invention will be described in further detail with 3 reference to the accompanying drawings, in which:
4 Fig. l is a block diagram of a cordless telephone system embodying 5 the present invention;
6 Fig. 2 is an illustration of details of the system of Fig. 1;
7 Figs. 3a and 3b are flow diagrams of the access unit and each 8 cordless telephone, respectively, when an outgoing call is originated from 9 one of the cordless telephones;
Figs. 4a and 4b are flow diagrams of the access unit and a newly 11 installed cordless telephone, respectively, illustrating a registration 1 2 process; and 13 Figs. 5a and 5b are flow diagrams of an existing cordless telephone 14 and the access unit, respectively, illustrating a modified registration 1 5 process.
17 In Fig. 1, a plurality of portable cordless telephones 1011 to 101n 18 form a cordless telephone system with a radio access unit 1 which is 19 connected through a subscriber loop 2 to a line terminal of a switched 2 0 telephone network 20. The cordless telephone system is assigned a unique 21 system identification number to distinguish it from other cordless 22 telephone systems. Each of the cordless telephones 101 has a product 23 identification number which is unique to it and no other cordless 24 telephones of the same product type have the same number and a 25 telephone identification number which is unique to it only in the own 2 6 cordless telephone system. As shown in Fig. ~, access unit 1 is a main 1~ ~i8 telephone of the cordless telephone system and operates as an interface 2 for manually completing incoming calls from the telephone network 20 to 3 one of the cordless telephones 101 with the aid of an attendant personnel 4 in a manner similar to conventional key telephone systems and for automatically relaying dialled information of an outgoing call to the 6 telephone network or establishing an intercom call between cordless 7 telephones of the same system. Access unit 1 includes a line interface 8 circuit 3 coupled to the telephone network 2 via the subscriber loop 2, a 9 handset 4 coupled to the line interface circuit 3, a loop control circuit 5, a transmit/receive unit 6 which selectively establishes a two-way radio 1 1 channel with any of the cordless portable telephones 101. A controller 7 is12 provided for controlling the line interface circuit 3, loop control circuit 5 13 and transmit/receive unit 6 in response to a ringing signal from the 14 network 20 or in response to an off-hook signal received from the cordless l S telephones 101 and further in response to a signal from a talk key 8 and a 1 6 numeric key pad 11 when originating an outgoing call from the access unit l 7 or forwarding an incoming call from the network to the cordless 18 telephones. The system identification number is stored in a read-only 19 memory 10, which is addressed by the controller 7 whenever an off-hook signal is received from a cordless telephone to check the stored system 21 identification number against one sent from the cordless telephone to 2 2 verify that it belongs to the own cordless telephone system.
2 3 Each portable telephone 101 comprises a transmit/receive unit 102, a 2 4 loop control circuit 103, a handset 104, a controller 105, a talk key 106, a 2s tone ringer 107 and an electrically erasable programmable read-only 2 6 memory 108 which stores the system identification number assigned at the 18~34 shipment of the system from the factory, the product identification number 2 assigned to each portable telephone at the stage of product and a 3 telephone identification number assigned at the site of installation. The 4 stored information is retained in a nonvolatile manner to be used for 5 establishing calls. A numeric keypad 109 is also connected to the controller 6 105 for generating a dialling signal.
7 When originating an outgoing call, the user depresses the talk key g 106. As specifically shown in Figs. 3a and 3b, the controller 105 of a call-9 originating telephone 101 checks to see if the talk key 106 is depressed (step 10 301) and, if it is, controller 105 retrieves the system identification number 1 1 from the memory 108 and sends it to the access unit 1 as an off-hook signal 1 2 through the transmit/receive unit 102 (step 302). On receiving the off-1 3 hook signal from the cordless telephone (step 201), the controller 7 of 1 4 access unit 1 compares it with the system identification number stored in 1 S memory 10. If they match (step 202), controller 7 returns the system 1 6 identification number as a proceed-to-send signal (step 203) and activates l 7 the loop control circuit 5 (step 204) to form a DC loop across the subscriber l 8 line terminal. Dial tone from the telephone network can therefore be 1 9 heard by the originating telephone.
2 0 On receiving the proceed-to-send signal (step 303), the controller 105 2 1 of the originating telephone reads the system identification number out of 22 the memory 108 for comparison with the received system identification 2 3 number. If they match (step 304), controller 105 activates the loop control 2 4 circuit 103 (step 305) to connect the handset 104 to the transmit/receive unit 2 S 102 to receive the dial tone from the access unit 1 and connects the keypad 2 6 10~ to the transmit/receive unit to allow the caller to operate the keypad ~!31.8~'34 Ni~-156 109 to send a dialling signal to the access unit 1 (steps 306 and 307). The 2 dialled information is received by the access unit and relayed to the 3 telephone network (steps 205 and 206).
4 Although not shown in detail, incoming calls are handled in a s manner inverse to that shown above. Namely, when completing an 6 incoming call from the access unit 1, a ringing signal is detected by the 7 controller 105 and the tone ringer 107 is activated to urge the user to 8 operate the talk key 106 for signalling. answer .of the calL Controller 105 g responds to it by activating the loop control circuit 103 to couple the 0 handset 104 to the transmit/receive unit 102 to establish a connection.
1 1 When installing a new cordless telephone, a servicing personnel first 2 visits the site where it is installed and then visits the site of the access unit.
1 3 The personnel enters the product identification number of the new 1 4 telephone into a random access memory of the controller 7 of the access 15 unit and assigns a unique telephone identification number and enters it 1 6 into the RAM as shown in step 211 in Fig. 4a. Controller 7 then sends the 1 7 product identification number to the new cordless telephone as a setup 1 8 signal (step 212). On receiving the setup signal (step 311), controller 105 of 1 9 the new cordless telephone checks whether the received product 2 0 identification number coincides with one stored in the memor,v 108 (step 2 1 312). If they match, the controller 105 returns the product identification 2 2 number stored in the memory 105 to the access unit as a proceed-to-send 2 3 signal (step 313). On receiving this signal (step 213), the controller 7 checks 24 whether the received product identification number comcides with the 2 5 previously entered number to verify that the new cordless telephone has 26 correctly received the setup signal (step 214). If coincidence occurs, controller 7 reads the system identification number from the read-only 2 memory 10 and the telephone identification number from the random 3 access memory of the controller 7 and sends them as an ID registration 4 signal to the new cordless telephone (step 215). On receiving the ID
5 registration signal (step 314), controller 105 of the new cordless telephone 6 stores the received system identification number and telephone 7 identification number into the electrically erasable PROM 108 (step 315).
8 Instead of visiting the site of the access unit, the servicing personnel 9 may visit the site of an existing cordless telephone to send a registration 10 request signal to the access unit 1. As shown in Figs. 5a and 5b, the 1 l servicing personnel first enters the product identification number of the 12 new cordless telephone into a random access memory of the controller 105 13 of the existing telephone using its numeric keypad 109 and then enters the 14 system identification number and a newly assigned telephone 15 identification number (step 401). Controller 105 of the existing telephone 16 now sends the entered numbers as a registration request signal to the 17 access unit (step 402). On receiving the registration request signal (step 18 501), controller 7 of the access unit stores the received signal into the 19 random access memory of the controller and proceeds to step 212 of Fig.
2 0 4a to transmit the product identification number to the new telephone as a 21 setup signal.
2 2 The foregoing description shows only preferred embodiments of the 2 3 present invention. Various modifications are apparent to those skilled in 2 4 the art without departing from the scope of the present invention which is 2 S only limited by the appended claims. Therefore, the embodiments shown 2 6 and described are only illustrative, not restrictive.
Figs. 4a and 4b are flow diagrams of the access unit and a newly 11 installed cordless telephone, respectively, illustrating a registration 1 2 process; and 13 Figs. 5a and 5b are flow diagrams of an existing cordless telephone 14 and the access unit, respectively, illustrating a modified registration 1 5 process.
17 In Fig. 1, a plurality of portable cordless telephones 1011 to 101n 18 form a cordless telephone system with a radio access unit 1 which is 19 connected through a subscriber loop 2 to a line terminal of a switched 2 0 telephone network 20. The cordless telephone system is assigned a unique 21 system identification number to distinguish it from other cordless 22 telephone systems. Each of the cordless telephones 101 has a product 23 identification number which is unique to it and no other cordless 24 telephones of the same product type have the same number and a 25 telephone identification number which is unique to it only in the own 2 6 cordless telephone system. As shown in Fig. ~, access unit 1 is a main 1~ ~i8 telephone of the cordless telephone system and operates as an interface 2 for manually completing incoming calls from the telephone network 20 to 3 one of the cordless telephones 101 with the aid of an attendant personnel 4 in a manner similar to conventional key telephone systems and for automatically relaying dialled information of an outgoing call to the 6 telephone network or establishing an intercom call between cordless 7 telephones of the same system. Access unit 1 includes a line interface 8 circuit 3 coupled to the telephone network 2 via the subscriber loop 2, a 9 handset 4 coupled to the line interface circuit 3, a loop control circuit 5, a transmit/receive unit 6 which selectively establishes a two-way radio 1 1 channel with any of the cordless portable telephones 101. A controller 7 is12 provided for controlling the line interface circuit 3, loop control circuit 5 13 and transmit/receive unit 6 in response to a ringing signal from the 14 network 20 or in response to an off-hook signal received from the cordless l S telephones 101 and further in response to a signal from a talk key 8 and a 1 6 numeric key pad 11 when originating an outgoing call from the access unit l 7 or forwarding an incoming call from the network to the cordless 18 telephones. The system identification number is stored in a read-only 19 memory 10, which is addressed by the controller 7 whenever an off-hook signal is received from a cordless telephone to check the stored system 21 identification number against one sent from the cordless telephone to 2 2 verify that it belongs to the own cordless telephone system.
2 3 Each portable telephone 101 comprises a transmit/receive unit 102, a 2 4 loop control circuit 103, a handset 104, a controller 105, a talk key 106, a 2s tone ringer 107 and an electrically erasable programmable read-only 2 6 memory 108 which stores the system identification number assigned at the 18~34 shipment of the system from the factory, the product identification number 2 assigned to each portable telephone at the stage of product and a 3 telephone identification number assigned at the site of installation. The 4 stored information is retained in a nonvolatile manner to be used for 5 establishing calls. A numeric keypad 109 is also connected to the controller 6 105 for generating a dialling signal.
7 When originating an outgoing call, the user depresses the talk key g 106. As specifically shown in Figs. 3a and 3b, the controller 105 of a call-9 originating telephone 101 checks to see if the talk key 106 is depressed (step 10 301) and, if it is, controller 105 retrieves the system identification number 1 1 from the memory 108 and sends it to the access unit 1 as an off-hook signal 1 2 through the transmit/receive unit 102 (step 302). On receiving the off-1 3 hook signal from the cordless telephone (step 201), the controller 7 of 1 4 access unit 1 compares it with the system identification number stored in 1 S memory 10. If they match (step 202), controller 7 returns the system 1 6 identification number as a proceed-to-send signal (step 203) and activates l 7 the loop control circuit 5 (step 204) to form a DC loop across the subscriber l 8 line terminal. Dial tone from the telephone network can therefore be 1 9 heard by the originating telephone.
2 0 On receiving the proceed-to-send signal (step 303), the controller 105 2 1 of the originating telephone reads the system identification number out of 22 the memory 108 for comparison with the received system identification 2 3 number. If they match (step 304), controller 105 activates the loop control 2 4 circuit 103 (step 305) to connect the handset 104 to the transmit/receive unit 2 S 102 to receive the dial tone from the access unit 1 and connects the keypad 2 6 10~ to the transmit/receive unit to allow the caller to operate the keypad ~!31.8~'34 Ni~-156 109 to send a dialling signal to the access unit 1 (steps 306 and 307). The 2 dialled information is received by the access unit and relayed to the 3 telephone network (steps 205 and 206).
4 Although not shown in detail, incoming calls are handled in a s manner inverse to that shown above. Namely, when completing an 6 incoming call from the access unit 1, a ringing signal is detected by the 7 controller 105 and the tone ringer 107 is activated to urge the user to 8 operate the talk key 106 for signalling. answer .of the calL Controller 105 g responds to it by activating the loop control circuit 103 to couple the 0 handset 104 to the transmit/receive unit 102 to establish a connection.
1 1 When installing a new cordless telephone, a servicing personnel first 2 visits the site where it is installed and then visits the site of the access unit.
1 3 The personnel enters the product identification number of the new 1 4 telephone into a random access memory of the controller 7 of the access 15 unit and assigns a unique telephone identification number and enters it 1 6 into the RAM as shown in step 211 in Fig. 4a. Controller 7 then sends the 1 7 product identification number to the new cordless telephone as a setup 1 8 signal (step 212). On receiving the setup signal (step 311), controller 105 of 1 9 the new cordless telephone checks whether the received product 2 0 identification number coincides with one stored in the memor,v 108 (step 2 1 312). If they match, the controller 105 returns the product identification 2 2 number stored in the memory 105 to the access unit as a proceed-to-send 2 3 signal (step 313). On receiving this signal (step 213), the controller 7 checks 24 whether the received product identification number comcides with the 2 5 previously entered number to verify that the new cordless telephone has 26 correctly received the setup signal (step 214). If coincidence occurs, controller 7 reads the system identification number from the read-only 2 memory 10 and the telephone identification number from the random 3 access memory of the controller 7 and sends them as an ID registration 4 signal to the new cordless telephone (step 215). On receiving the ID
5 registration signal (step 314), controller 105 of the new cordless telephone 6 stores the received system identification number and telephone 7 identification number into the electrically erasable PROM 108 (step 315).
8 Instead of visiting the site of the access unit, the servicing personnel 9 may visit the site of an existing cordless telephone to send a registration 10 request signal to the access unit 1. As shown in Figs. 5a and 5b, the 1 l servicing personnel first enters the product identification number of the 12 new cordless telephone into a random access memory of the controller 105 13 of the existing telephone using its numeric keypad 109 and then enters the 14 system identification number and a newly assigned telephone 15 identification number (step 401). Controller 105 of the existing telephone 16 now sends the entered numbers as a registration request signal to the 17 access unit (step 402). On receiving the registration request signal (step 18 501), controller 7 of the access unit stores the received signal into the 19 random access memory of the controller and proceeds to step 212 of Fig.
2 0 4a to transmit the product identification number to the new telephone as a 21 setup signal.
2 2 The foregoing description shows only preferred embodiments of the 2 3 present invention. Various modifications are apparent to those skilled in 2 4 the art without departing from the scope of the present invention which is 2 S only limited by the appended claims. Therefore, the embodiments shown 2 6 and described are only illustrative, not restrictive.
