Method and apparatus for handover in mobile network, and mobile terminal thereof

An apparatus for performing handover in a mobile communication network, comprising:

• a data reception unit that receives user information including information about user requirement and information about signal intensity of mobile networks to which a user terminal can be connected;
• a determination unit that selects at least one of connectable mobile networks using the received user information and signal intensity information as a network for handover;
• and
• a data transmission unit that requests approval of handover of the user terminal to the selected network for handover,
• wherein the data reception unit receives result information about the approval request from the network for handover, and the data transmission unit transmits information about a network in which handover is approved among the networks for handover to the user terminal.

A mobile communication terminal comprising:

• a signal intensity detection unit that detects signal intensity of connectable mobile networks;
• a comparison unit that compares signal intensity and a reference value of a currently connected mobile network and those of the connectable mobile networks;
• a data transmission and reception unit that transmits user information including information about mobile networks whose signal intensity is equal to or greater than a reference value and information about user requirement to a base station and that receives information about a network for handover selected according to the transmitted user information among the mobile networks;
• and
• a handover performing unit that performs handover to the selected network for handover.
