Method of efficiently processing dormant state in packet service and multi-mode terminal for the same
First Claim
1. A method of processing a dormant state in a packet service, which is performed by a multi-mode terminal comprising first and second modems supporting different communication services, the method comprising:
- if it is determined that the multi-mode terminal has entered into the dormant state during a packet service through a first communication network, determining whether a command received from the first communication network corresponds to a command for connecting a packet call to a second communication network, requesting the first communication network to disconnect the packet call when it is determined that the command received from the first communication network corresponds to the command for connecting the packet call to the second communication network, monitoring whether an intensity of a signal of a communication state with the first communication network falls below a threshold value in the dormant state during a predetermined period when it is determined that the command received from the first communication network does not correspond to the command for connecting the packet call to the second communication network, wherein the dormant state is a state in which an application using the packet service is operating but not transmitting or receiving data to or from the first communication network;
setting a count value if it is determined that the intensity of the signal during the predetermined period is less than the threshold;
if the count value is equal to a threshold counting value, requesting the first communication network to disconnect the packet call;
when it is determined thatif the packet call with the first communication network is disconnected, turning on the second modem, by the first modem, through a communication path coupling the first and second modems;
determining whether registration between the second modem and the second communication network succeeds; and
if the registration succeeds, connecting a packet call to the second communication network by the second modem.

Abstract
An apparatus and method for efficiently processing a dormant state in a packet service between communication networks providing the packet service using different mobile communication technologies is disclosed. This method includes disconnecting, by a multi-mode terminal, a current packet call and changing to a new serviceable mode, if a multi-mode terminal moves to a poor communication area in a dormant or preservation state occurring during a packet service. In this state, by immediately returning to a packet call reconnection state if a user performs a subsequent operation, an area in which the packet service cannot be provided can be minimized, and a communication mode in which a best communication service can be provided can be established.

5. A multi-mode terminal, comprising:
-
first and second modems supporting different communication services, for efficiently processing a dormant state in a packet service, the first modem for, when it is determined that the multi-mode terminal has entered into the dormant state during a packet service through a first communication network, determining whether a command received from the first communication network corresponds to a command for connecting a packet call to a second communication network, requesting the first communication network to disconnect the packet call if it is determined that the command received from the first communication network corresponds to the command for connecting the packet call to the second communication network, monitoring whether an intensity of signal of a communication state with the first communication network falls below a threshold value in the dormant state during a predetermined period if it is determined that the command received from the first communication network does not correspond to the command for connecting the packet call to the second communication network, wherein the dormant state is a state in which an application using the packet service is operating but not transmitting or receiving data to or from the first communication network, setting a count value if it is determined that the intensity of the signal during the predetermined period is less than the threshold, requesting the first communication network to disconnect a packet call if the count value is equal to a threshold counting value, turning on the second modem through a communication path coupling the first and second modems if the packet call with the first communication network is disconnected in response to the request; and the second modem for determining whether registration between the second modem and the second communication network succeeds, and connecting the packet call to the second communication network if the registration succeeds. - View Dependent Claims (6, 7, 8)

9. A method of processing a dormant state in a packet service, which is performed by a multi-mode terminal having first and second modems supporting different communication services, the method comprising:
-
if it is recognized that the multi-mode terminal has entered the dormant state during a packet service in a first communication network mode, determining whether the multi-mode terminal is located in a communication area receiving a signal having a lower intensity than a threshold, in the dormant state, by determining whether a command for changing to a second communication network is set by checking a command received from the first communication network, activating a ping-pong timer if the command for changing to the second communication network is set, and repeating the determination of whether the multi-mode terminal is located in the communication area receiving the signal having the lower intensity than the threshold when the ping-pong timer expires, wherein the dormant state is a state in which an application using the packet service is operating but not transmitting or receiving data to or from the first communication network; if it is determined that the multi-mode terminal is located in the communication area receiving the signal having the lower intensity than the threshold, commanding the second modem, through a communication path coupling the first and second modems, to perform location registration in the second communication network;
the location registration succeeds, continuing performance of the packet service by changing to a second communication network mode and deleting an Internet Protocol (IP) address and Quality of Service (QoS) information assigned in the first communication network mode; andcanceling the change to the second communication network mode and returning to the first communication network mode if the location registration fails. - View Dependent Claims (10, 11)
