Method of handling data transmission associated with natural disaster notification in a wireless communication system and related apparatus

A method of handling data transmission associated with natural disaster notification for a network of a wireless communication system, the method comprising:

• the network configuring a plurality of component carriers for data transmission to a mobile device;
• the network segmenting a natural disaster notification message into a plurality of segments;
• and
• a plurality of base stations of the network separately transmitting the plurality of segments to the mobile device and each of the plurality of base stations transmitting the plurality of segments on only one of the plurality of component carriers;
• wherein the network segmenting the natural disaster notification message into the plurality of segments comprises each of the plurality of base stations of the network separately segmenting the natural disaster notification message into the plurality of segments.

A mobile device for handling data transmission associated with natural disaster notification in a network of a wireless communication system, the mobile device comprising:

• a processing means;
• a memory unit;
• and
• a program code, stored in the memory unit, for instructing the processing means to execute the following steps:
• activating a plurality of component carriers for data reception in a radio resource control connected mode;
• receiving segments of a natural disaster notification message via only one of the plurality of component carriers;
• and
• concatenating the received segments of the natural disaster notification message, wherein the natural disaster notification message is segmented into the segments by the network, and all of the segments are transmitted from the network to the mobile device on the only one component carrier.
