Abstract

Cordless telephone equipment includes a portable unit and a base unit. The base unit includes: a portable unit control section controlling a communication protocol with the portable unit through a wireless interface wirelessly connecting with the non-IP terminal type portable unit; a wireless LAN interface section transmitting and receiving packet data to and from a wireless IP terminal and wireless LAN access point; a wireless LAN bridge control section forwarding the received packet data to the wireless IP terminal, or the wireless LAN access point, or within the base unit in accordance with a destination address of the packet data received through the wireless LAN interface section; and a base unit control section processing the packet data received from the wireless IP terminal and forwarded within the base unit, as data received from a portable unit under control of the base unit.

Claims

1. Cordless telephone equipment comprising:

a portable unit that is a non IP terminal; and

a base unit that connects with the portable unit wirelessly, wherein

the base unit comprises;

a portable unit control section that controls a communication protocol between the base unit and the portable unit through a wireless interface that wirelessly connects with the portable unit of the non IP terminal type;

a wireless LAN interface section that transmits and receives packet data to and from a wireless IP terminal and a wireless LAN access point;

a wireless LAN bridge control section that forwards the received packet data to the wireless IP terminal, the wireless LAN access point, or within the base unit in accordance with a destination address of the packet data received through the wireless LAN interface section; and

a base unit control section that processes the packet data received from the wireless IP terminal and forwarded within the base unit, as data received from a portable unit under control of the base unit.

2. The cordless telephone equipment according to claim 1, wherein

the base unit further comprises:

a portable unit registration section that receives a portable unit registration request message from the wireless IP terminal and that registers the wireless IP terminal as a portable unit, wherein

the base unit control section processes, as data received from a portable unit under control of the base unit, packet data received from the wireless IP terminal registered by the portable unit registration section.

3. The cordless telephone equipment according to claim 2, wherein

the base unit further comprises:

a portable unit authorization section that receives a portable unit authorization request message from the wireless IP terminal registered by the portable unit registration section, and that confirms an terminal identity between the wireless IP terminal and the portable unit registered by the portable unit registration section, using an authorization ID and an authorization password that are included in the portable unit authorization request message, wherein

the base unit control section processes, as data received from a portable unit under control of the base unit, the packet data received from the wireless IP terminal for which the terminal identity is confirmed.

4. The cordless telephone equipment according to claim 1, wherein

the base unit further comprises:

a portable unit authorization section that receives a portable unit authorization request message from a wireless IP terminal previously registered in a storage section, and that confirms an terminal identity between the wireless IP terminal and the registered portable unit, using an authorization ID and an authorization password that are included in the portable unit authorization request message, wherein

the base unit control section processes, as data received from a portable unit under control of the base unit, packet data received from the wireless IP terminal for which the terminal identity is confirmed.

5. The cordless telephone equipment according to claim 3, wherein:

the authorization ID is identification information of the wireless IP terminal; and

the authorization password is a MAC address of the wireless IP terminal

6. The cordless telephone equipment according to claim 4, wherein:

the authorization ID is identification information of the wireless IP terminal; and

the authorization password is a MAC address of the wireless IP terminal

7. The cordless telephone equipment according to claim 1, wherein

the base unit further comprises:

a base unit search section that, upon receiving a base unit search message from the wireless IP-type terminal, replies with address information of the base unit to the wireless IP-type terminal

8. The cordless telephone equipment according to claim 7, wherein the address information of the base unit is a MAC address of the base unit and an IP address of a call control server.

9. The cordless telephone equipment according to claim 3, further comprising:

a storage section that accumulates portable unit additional information including a communication history for each of the portable units; and

a base unit control section that, when the terminal identity for the wireless IP terminal is confirmed, indicates to the wireless IP terminal, the portable unit additional information corresponding to the wireless IP terminal.

10. The cordless telephone equipment according to claim 3, comprising:

a storage section that accumulates portable unit additional information including a communication history for each of the portable units; and

a base unit control section that, when a portable unit additional information request message is received from the wireless IP terminal, indicates to the wireless IP terminal, the portable unit additional information corresponding to the wireless IP terminal

11. The cordless telephone equipment according to claim 3, wherein

the portable unit additional information is short message information that includes a date and time of generation of a short message in the portable unit, a phone number of another party, and a text message.

12. The cordless telephone equipment according to claim 3, wherein

the portable unit additional information is call history information that includes a time of occurrence of an outgoing and incoming call at the portable unit and a phone number of another party.

13. A cordless telephone system comprising:

the cordless telephone equipment according to claim 1; and

a wireless IP terminal that transmits and receives packet data to and from a base unit of the cordless telephone equipment through a wireless LAN, and whose calls are to be controlled as a portable unit under control of the base unit.

14. A communication method in cordless telephone equipment comprising a portable unit that is a non IP terminal and a base unit that wirelessly connects with the portable unit, the communication method being used for the base unit that transmits and receives packet data to and from a wireless IP terminal and a wireless LAN access point, the communication method comprising:

receiving packet data from the wireless IP terminal or the wireless LAN access point;

forwarding the received packet data to the wireless IP terminal, the wireless LAN access point, or within the base unit in accordance with a destination address of the received packet data; and

processing packet data received from the wireless IP terminal and forwarded within the base unit, as data received from a portable unit under control of the base unit.
