Mobile terminal and communication mode switching method thereof

A communication mode switching method for a mobile terminal, the method comprising:

• determining whether a request for a second mode communication session is detected while the mobile terminal is in a first mode communication session with a network via a first interface;
• resynchronizing, when a request for a second mode communication session is detected, a Point-to-Point Protocol (PPP) link with the network;
• initializing and reactivating the first interface with the resynchronized PPP link;
• re-registering a Mobile Internet Protocol (MIP) with the network;
• acquiring an IP address as a consequence of the re-registration of the MIP;
• and
• communicating data with the network using the acquired IP address.

A mobile terminal comprising:

• a storage unit configured to store a Mobile Internet Protocol (MIP) and a mobile browser for running a first mode communication session established via a first interface and a Point-To-Point Protocol (PPP) for initializing and activating the first interface and a second interface to establish the first mode communication and a second mode communication session that is establish via the second interface;
• a radio communication unit configure to establish a communication link with a network via at least one of the first and second interfaces, the communication link configured for the first mode communication session and the second mode communication session;
• and
• a control unit configured to initialize and activate the second interface when a request for the second mode communication session is detected during the first mode communication session, synchronizes the first interface and the second interface, re-registers a Mobile Internet Protocol (MIP) with the network, acquires an IP address as a consequence of the re-registration of the MIP, and communicates data with the network using the acquired IP address.
