QoS control apparatus in multi-cell network system and method thereof

A quality of service (QoS) information control method for controlling QoS information and improving a communication QoS, the QoS information control method comprising:

• a) detecting an area range that guarantees requested QoS information and determining whether there is a mobile communication system for processing the requested QoS information, when receiving a traffic service request signal that requests a traffic service process;
• b) detecting characteristics of the mobile communication system and determining the mobile communication system for guaranteeing the requested QoS information, when determining in a) that there is the mobile communication system;
• and
• c) processing a traffic service according to multimedia traffic characteristics when determining the mobile communication system for guaranteeing the requested QoS information:
• b1) generating and transmitting a readjusted request message having a system parameter for guaranteeing the requested QoS information when the mobile communication system for guaranteeing the requested QoS information is not determined;
• b2) using the system parameter in the readjusted request message, generating readjusted weight information for selecting a second mobile communication system for guaranteeing the requested QoS information, and transmitting the readjusted weight information;
• and
• b3) using the readjusted weight information, and determining the second mobile communication system for providing second best readjusted QoS information.
