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 the steps of:
- if it is determined that the multi-mode terminal has entered into the dormant state during a packet service through a first communication network, monitoring whether a communication state with the first communication network is bad in the dormant state;
if it is determined that the communication state with the first communication network is bad, requesting the first communication network to disconnect a packet call; and
when it is determined that the packet call with the first communication network is disconnected, performing the packet service by connecting a packet call to a second communication network.

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.

9. 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 monitoring whether a communication state with a first communication network is bad in the dormant state if it is determined that the multi-mode terminal has entered into the dormant state during a packet service through the first communication network, requesting the first communication network to disconnect a packet call if the communication state with the first communication network is determined to be bad, and commanding the second modem to perform the packet service by connecting a packet call through a second communication network if the packet call with the first communication network is disconnected in response to the request; and
the second modem for registering into the second communication network in response to the command of the first modem and performing the packet service by connecting the packet call to the second communication network if the registration succeeds. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. 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 the steps of:
-
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 bad communication area in the dormant state;
if it is determined that the multi-mode terminal is located in a bad communication area, commanding the second modem, through a communication path coupling the first and second modems, to perform location registration in the second communication network; and
if the location registration succeeds, changing to a second communication network mode. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. 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 monitoring whether the multi-mode terminal is located in a bad communication area in the dormant state if it is determined that the multi-mode terminal had entered into the dormant state during a packet service in a first communication network mode, and commanding the second modem through a communication path, which couples the first and second modems, to perform location registration in a second communication network if it is determined that the multi-mode terminal is located in a bad communication area; and
the second modem for performing the location registration in the second communication network in response to the command of the first modem and performing a second communication network mode if the location registration succeeds. - View Dependent Claims (25, 26, 27, 28)
