Communication terminal and communication system

Abstract

The communication terminal and a communication system is capable of eliminating necessity of complicated setting inputs related to communication in a communication terminal in performing dial-up connection to a communication apparatus on a network from the communication terminal. Since the communication terminal and the communication system are provided with a receiving device which receives connection information such as a dial-up telephone number, attribute information, a URL, an IP address, gateway information and a DNS that is required for making communication connection to a photograph sharing service on the Internet from a cellular phone and a transmitting and receiving device (transmitting and receiving device) which sends and receives information such as an image to and from the photograph sharing service based on the connection information received from the cellular phone, it becomes possible to eliminate necessity of complicated setting inputs related to communication in an electronic camera in performing dial-up connection to the Internet from the electronic camera.

1 . A communication terminal which is capable of sending and receiving information to and from a communication apparatus on a network via a cellular phone, the communication terminal comprising: 
 a receiving device which receives connection information for making communication connection to the communication apparatus on the network from the cellular phone; and    a transmitting and receiving device which sends and receives information to and from the communication apparatus on the network based on the connection information received from the cellular phone,    wherein said communication terminal is separate from the cellular phone and is locally positioned relative to the cellular phone when receiving the connection information.    
     
     
         2 . The communication terminal according to  claim 1 , further comprising a displaying device which shows the user the connection information received from the cellular phone.  
     
     
         3 . The communication terminal according to  claim 1 , further comprising: 
 a recording device which records a batch file in which a file name to be sent or received or a content of a service is written in advance,    wherein the transmitting and receiving device reads out the batch file related to the communication apparatus on the network to and from which information is sent or received and sends the batch file to the communication apparatus on the network.    
     
     
         4 . The communication terminal according to  claim 1 , wherein the connection information includes at least one of a dial-up telephone number, attribute information, a URL, an IP address, gateway information and a DNS.  
     
     
         5 . The communication terminal according to  claim 1 , further comprising: 
 an inputting device with which a user designates the communication apparatus on the network based on the connection information received from the cellular phone,    wherein the transmitting and receiving device sends and receives information to and from the designated communication apparatus on the network based on the connection information received from the cellular phone.    
     
     
         6 . The communication terminal according to  claim 5 , further comprising a displaying device which shows the user the connection information received from the cellular phone.  
     
     
         7 . A communication terminal which is capable of sending and receiving information to and from a communication apparatus on a network via a cellular phone, the communication terminal comprising: 
 a receiving device which receives a menu of destinations of communication for making communication connection to the communication apparatus on the network;    an inputting device which sets the communication apparatus on the network based on the menu received from the cellular phone; and    a transmitting and receiving device which sends information of the designated communication apparatus on the network to the cellular phone, causes the cellular phone to send connection information to the communication apparatus on the network and thereafter connects communication with the designated communication apparatus on the network to send and receive information,    wherein said communication terminal is separate from the cellular phone and is locally positioned relative to the cellular phone when receiving the menu of destinations.    
     
     
         8 . The communication terminal according to  claim 7 , further comprising: 
 a recording device which records a batch file in which a file name to be sent or received or a content of a service is written in advance,    wherein the transmitting and receiving device reads out the batch file related to the communication apparatus on the network to and from which information is sent or received and sends the batch file to the communication apparatus on the network.    
     
     
         9 . The communication terminal according to  claim 7 , wherein the connection information includes at least one of a dial-up telephone number, attribute information, a URL, an IP address, gateway information and a DNS.  
     
     
         10 . The communication terminal according to  claim 1 , wherein said communication terminal is a digital camera unit.  
     
     
         11 . The communication terminal according to  claim 10 , wherein said digital camera further comprises: 
 a display for displaying connection information received from the cellular phone,    wherein the user selects a destination for a digital photographic image based on the displayed connection information.    
     
     
         12 . The communication terminal according to  claim 10 , wherein said digital camera further comprises: 
 a mode switching element, which switches between a photographing mode for generating a digital image, and a communication mode for communicating a digital image to a destination based on connection information received from the cellular phone.    
     
     
         13 . The communication terminal according to  claim 7 , wherein said communication terminal is a digital camera unit.  
     
     
         14 . The communication terminal according to  claim 13 , wherein said digital camera further comprises: 
 a display for displaying a menu of destinations received from the cellular phone,    wherein the user selects a destination for a digital photographic image based on the displayed menu of destinations.    
     
     
         15 . The communication terminal according to  claim 13 , wherein said digital camera further comprises: 
 a mode switching element, which switches between a photographing mode for generating a digital image, and a communication mode for communicating a digital image to a destination based on the menu of destinations received from the cellular phone.
