Method and apparatus for setting network using DHCP server or client function
First Claim
1. A terminal device connected to a network being served by a first device having a DHCP server function, comprising:
- means for performing a DHCP client function;
receiving means for receiving a signal indicating that a second device having a DHCP server function is connected to said network, the second device providing a service desired by the terminal device; and
operation control means for operating said means for performing a DHCP client function when said receiving means receives said signal,wherein said DHCP client function comprises a function for using an IP address assigned by said second device as its own IP address, andwherein the IP address assigned by said second device is different from the IP address assigned by said first device having a DHCP server function.

Abstract
A PC activates a software program for detecting when a network terminal device is connected to a network, based on the control action of the user. When the network terminal device is connected to the network, the network terminal device sends a connection signal to the PC, and then operates as a DHCP server. Having received the connection signal, the PC recognizes an IP address of the network terminal device that is included in the connection signal, and operates as a DHCP client. The PC makes its own network setting using an IP address assigned from a DHCP server that has the same IP address as the IP address of the network terminal device.

5. A first service providing device having a DHCP server function and a DHCP client function and connected to a network, comprising:
-
detecting means for detecting whether, a second service providing unit device having a DHCP server function and a DHCP client function, for providing the same service as the service provided by the first service providing device, is connected as a DHCP server to said network; and operation control means for performing selectively the DHCP server function and the DHCP client function based on a detected result from said detecting means. - View Dependent Claims (6, 7, 8)

11. A network setting method to be carried out by a terminal device having a DHCP client function and connected to a network being served by a first device having a DHCP server function, the method comprising:
-
receiving a signal indicating that second device having a DHCP server function is connected to said network, the second device providing a service desired by the terminal device; and performing the DHCP client function when said signal is received, wherein said DHCP client function comprises a function for using an IP address assigned by said second device as its own IP address, and wherein the IP address assigned by said second device is different from the IP address assigned by said first device having a DHCP server function. - View Dependent Claims (12, 13, 18)

14. An operation control method carried out by a service providing device having a DHCP server function and a DHCP client function and connected to a network, comprising the steps of:
-
detecting whether a service providing unit having a DHCP server function and a DHCP client function, for providing the same service as the service provided by the service providing device, is connected as a DHCP server to said network; and selectively performing the DHCP server function and the DHCP client function based on a detected result from said detecting step, wherein the service provided by the service providing device is a service other than DHCP server. - View Dependent Claims (15, 16, 17, 19)
