INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract The present invention discloses a portable routing device. One of the main features of the present invention is that the present invention utilizes a domain name signal as a switch on signal of a routing module of the portable routing device to maintain the off status of the routing module so as to saving power thereby. In another way, the present invention further capable of switching off the routing function thereof by determining if any network source having a higher priority exists so as to save the unnecessary waste of power. By avoiding the unnecessary routing action, the present invention is capable of saving power without affecting the normal use of the user. ## Claims ### Claim 1 A portable routing device, applied in a space comprising a network source and an electronic device having a B connection module and a B network module, wherein the B connection module is based on a connection protocol, the B network module is based on a routing protocol, comprising: a network name and address module, used to manage, identify and provide a domain position signal; an A connection module based on the connection protocol and coupled with the network name and address module; a routing module based on the routing protocol and coupled with the network name and address module, wherein the routing module has a working mode and a sleep mode, when the routing module is in the working mode, the routing module is coupled with the network source and has a routing network so that the electronic device may access the network source, and when the portable routing device is in the sleep mode, the routing module is turned off and independent of the B network module of the electronic device; and a control module coupled with the network name and address module, the A connection module and the routing module, used to control the switch and the operation of the network name and address module, the A connection module and the routing module; wherein, when the routing module is in the sleep mode, the A connection module of the portable routing device is coupled with the B connection module, when the A connection module receives a domain name signal from the electronic device, the network name and address module can obtain the domain name signal from the A connection module and return a corresponding domain position signal to the electronic device, and the control module switches the portable routing device into the working mode from the sleep mode. ### Claim 2 (depends on 1) The portable routing device of claim 1, wherein when the control module switches the routing module into the working mode from the sleep mode, the control module also turns off the A connection module. ### Claim 3 (depends on 1) The portable routing device of claim 1, wherein the control module can automatically switch the routing module into the sleep mode from the working mode as long as the routing module meets a shutdown condition. ### Claim 4 (depends on 3) The portable routing device of claim 3, wherein the shutdown condition is a threshold of flow or flow rate, or a length of the duration which is corresponded to the threshold of flow or flow rate. ### Claim 5 (depends on 3) The portable routing device of claim 3, wherein the control module comprises a priority table which has the priority of a plurality of network sources and the routing network;
