Abstract:
There are provided a device and method for providing a mobile Internet call service. In order to reduce a call waiting time for an mVoIP call, when a call is an initial call after power of a terminal is turned on or using the main call number, information for a call connection is acquired in advance and a light weight session is maintained. When the mVoIP call is made later, the maintained light weight session is used to make a direct P2P call. Therefore, it is possible to reduce a call connection time. As a result, when the mVoIP call attempt is made, a call waiting time is significantly reduced and thus it is possible to provide a rapid response and improve user satisfaction. When the light weight session is maintained, access to a separate server system is not performed. As a result, it is possible to connect a P2P call even when call traffic is heavy.

Claim (Index 1):
A device for providing a mobile Internet call service, comprising:\n a communicator configured to perform communication for a mobile Internet call service; a memory configured to store a main call number list including at least one main call number or network address translation (NAT) information for a call connection; and a controller configured to:\n measure a number of call connection attempts of each call number of a plurality of call numbers for a predetermined amount of time; \n designate a priority of each call number of the plurality of call numbers in a descending order of the measured number of call connection attempts; \n set the main call number list of a predetermined number based on the designated priority; \n when power of the device is turned on, send a NAT signal that is configured to obtain NAT information for a mobile Internet call of the main call number; \n acquire the NAT information for a call connection and store the acquired NAT information; \n generate a light weight session using the NAT information and maintain the generated light weight session; and \n when a mobile Internet call request is made for the main call number, perform the call connection using the light weight session, and \n wherein the light weight session is in a state that the NAT information is stored in advance and a session for the call connection is maintained to reduce a waiting time for the call connection.
