Method and system of power saving and portable device using the same
First Claim
1. A method for performing communications in a portable device having a first module adapted for communications over a mobile communication network and a second module adapted for communications over a fixed telephone network, the method comprising:
- determining whether the portable device is located in a coverage area associated with the fixed telephone network by a predetermined period;
activating the second module when the portable device is located in the coverage area;
receiving, by the first module, a call connection request message from the mobile communication network while the portable device is;
(i) registered with both the mobile communication network and the fixed telephone network, and (ii) located in the coverage area;
refraining, by the first module, from conducting a call associated with the call connection request message;
transmitting, by the first module, to the mobile communication network a call transfer message requesting the call connection request message to be transferred onto the second module; and
when the call connection request message is received at the second module over the fixed telephone network, establishing, by the second module, the call over the fixed telephone network.

6. A system for performing communications, comprising:
-
a mobile communication network; a fixed telephone network; and a portable device, including a first module adapted for communications over the mobile communication network and a second module adapted for communications over the fixed telephone network, the portable device being configured to; determine whether the portable device is located in a coverage area associated with the fixed telephone network by a predetermined period; activate the second module when the portable device is located in the coverage area; receive, by the first module, a call connection request message from the mobile communication network while the portable device is;
(i) registered with both the mobile communication network and the fixed telephone network and (ii) located in the coverage area;refrain, by the first module, from conducting a call associated with the call connection request message; transmit, by the first module, to the mobile communication network a call transfer message requesting the call connection request message to be transferred onto the second module; and when the call connection request message is received at the second module over the fixed telephone network, establish by the second module the call over the fixed telephone network. - View Dependent Claims (7, 8, 9)

10. An electronic device comprising a first module adapted for communications over a mobile communication network, a second module adapted for communications over a fixed telephone network, and a processor configured to:
-
determine whether the electronic device is located in a coverage area associated with the fixed telephone network by a predetermined period; activate the second module when the electronic device is located in the coverage area; control the first module to receive a call connection request message from the mobile communication network while the device is;
(i) registered with both the mobile communication network and the fixed telephone network, and (ii) located in the coverage area;control the first module to refrain from conducting a call associated with the call connection request message; control the first module to transmit to the mobile communication network a call transfer message requesting the call connection request message to be transferred onto the second module; and when the call connection request message is received at the second module over the fixed telephone network, control the second module to establish the call over the fixed telephone network. - View Dependent Claims (11, 12, 13, 14)

15. An electronic device comprising a first module adapted for communications over a mobile communication network, a second module adapted for communications over a fixed telephone network, and a processor configured to:
-
determine whether the electronic device is located in a coverage area associated with the fixed telephone network by a predetermined period; activate the second module when the electronic device is located in the coverage area; control the first module to receive a first call connection request message at the first module, the first call connection request message being received over the mobile communication network while the electronic device is located in the coverage area; control the first module to transmit, to the mobile communication network, a call transfer message requesting the call connection request message to be transferred onto the second module; control the second module to receive a second call connection request message, the second call connection request message being received over the fixed telephone network, and the second call connection request message being generated based on information contained in the call transfer message; output an indication that the second call connection request message is associated with the first call connection request message; and control the second module to establish a call in response to the second call connection request message. - View Dependent Claims (16, 17)
