Apparatus and method for managing delay for TCP/IP communications in a mobile communication system

A method of a Base Station Controller (BSC) for managing a packet transmission delay for Transmission Control Protocol/Internet Protocol (TCP/IP)-based communications in a mobile communication system, comprising:

• imposing no random delay on a packet directed to a Mobile Station (MS) or a packet transmitted from the MS and sending the packet to the MS or corresponding MS, if it is determined that the MS starts to perform a handover during communications with the MS, under the TCP/IP-based communications;
• and
• delaying, according to a random delay, a packet directed to the MS or a packet transmitted from the MS and sending the delayed packet to the MS or corresponding MS, if it is determined that the MS has completed the handover during the packet transmission with no delay, under the TCP/IP-based communications.

An apparatus of a Base Station Controller (BSC) for managing a packet transmission delay for Transmission Control Protocol/Internet Protocol (TCP/IP)-based communications in a mobile communication system, comprising:

• a communication module for communicating with other nodes, under the TCP/IP-based communications;
• and
• a controller for imposing no random delay on a packet directed to a Mobile Station (MS) or a packet transmitted from the MS and sending the packet to the MS or corresponding MS through the communication module, when the MS starts a handover, and delaying, according to a random delay, a packet directed to the MS or a packet transmitted from the MS and sending the delayed packet to the MS or corresponding MS through the communication module, when the MS has completed the handover during the packet transmission with no delay, under the TCP/IP-based communications.
