Abstract:
1. A method of minimizing a delay time of a packet call reconnection in a multi-mode terminal having first and second modems supporting different communication services, the method comprising the steps of: receiving, by the first modem, a condition for beginning a packet call reconnection to a second communication network during a packet service, wherein the condition is defined by a first communication network; determining, by the first modem, whether the received packet call reconnection start condition is satisfied by monitoring a state of the packet service through the first communication network; if the packet call reconnection start condition is satisfied, receiving, by the second modem, a command from the first modem to reconnect a packet call to the second communication network to perform the packet service; and registering, by the second modem, into the second communication network in response to the command of the first modem, and connecting the packet call to the second communication network to perform the packet service, if the registration succeeds; wherein the first modem determines whether a measurement control message comprising the condition is received from the first communication network, monitors whether a state of the packet service through the first communication network satisfies the packet call reconnection start condition contained in the measurement control message, and transmits a measurement report message to the first communication network if the packet call reconnection start condition is satisfied.
