Dual mode terminal for supporting access in different network, network apparatus and operation method thereof
First Claim
1. A dual mode terminal for supporting an access in a different network, comprising:
- an interface to receive first network information from a first network apparatus and to receive second network information from a second network apparatus in response to each network information request;
a selection unit to select a single network apparatus based on the first network information and the second network information; and
a processing unit to transmit a call connection request to the selected network apparatus, and to control a communication with the selected network apparatus depending on whether the selected network apparatus allows a call connection,wherein the first network information is calculated from first quality information that is predicted by the first network apparatus based on a first packet generation rate and a first packet processing amount of a first network and includes a first gain value indicating a first quality of service (QoS) based on a first service cost per packet in the first network,wherein the second network information is calculated from second quality information that is predicted by the second network apparatus based on a second packet generation rate and a second packet processing amount of a second network and includes a second gain value indicating a second quality of service (QoS) based on a second service cost per packet in the second network,wherein the selection unit calculates a first quality utility value and a second quality utility value indicating a relationship between a QoS and a service cost corresponding to an amount of time when the call connection continues, based on the first gain value and the second gain value, and selects the first network apparatus when the first quality utility value is greater than the second quality utility value, or selects a network apparatus based on a network selected and input from a user.

3. An operation method of a dual mode terminal for supporting an access in a different network, the method comprising:
-
receiving first network information from a first network apparatus and receiving second network information from a second network apparatus in response to each network information request; selecting a single network apparatus based on the first network information and the second network information; and transmitting a call connection request to the selected network apparatus, and controlling a communication with the selected network apparatus depending on whether the selected network apparatus allows a call connection, wherein the first network information is calculated from first quality information that is predicted by the first network apparatus based on a first packet generation rate and a first packet processing amount of a first network and includes a first gain value indicating a first quality of service (QoS) based on a first service cost per packet in the first network, wherein the second network information is calculated from second quality information that is predicted by the second network apparatus based on a second packet generation rate and a second packet processing amount of a second network and includes a second gain value indicating a second quality of service (QoS) based on a second service cost per packet in the second network, wherein the selecting comprises calculating a first quality utility value and a second quality utility value indicating a relationship between a QoS and a service cost corresponding to an amount of time when the call connection continues, based on the first gain value and the second gain value, and selecting the first network apparatus when the first quality utility value is greater than the second quality utility value, or selecting a network apparatus based on a network selected and input from a user. - View Dependent Claims (4)
