Portable routing device and a routing method

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.
