Method and apparatus for offloading traffic in a wireless communication

A method performed by a second device processing traffic together with a first device in a communication system, the method comprising:

• measuring a packet transmission rate and a packet transmission delay time of the second device per unit time;
• delivering, to the first device, measurement information including a measurement value of the packet transmission rate and the packet transmission delay time measured per the unit time to the first device, the measurement information being used to determine whether to update a traffic processing rule by the first device;
• receiving, from the first device, information related to the traffic processing rule determined based on the measurement information;
• updating the traffic processing rule based on the information related to the traffic processing rule;
• processing first traffic related to the updated traffic processing rule in case of receiving the first traffic;
• and
• delivering, to the first device, second traffic that is not related to the updated traffic processing rule in case of receiving the second traffic.

A first device in a communication system, the first device comprising:

• a transceiver to transmit and receive a signal;
• and
• a controller connected to the transceiver,
• wherein the controller is configured to:
• detect a need to update a traffic processing rule in a second device processing traffic together with the first device,
• determine whether to update the traffic processing rule to be used in the second device based on performance information of the first device and performance profile information of the second device, and
• deliver, to the second device, information related to the update of the traffic processing rule based on the determination, and
• wherein the performance profile information of the second device includes:
• a maximum transmission capacity of a packet of the second device according to a number of traffic processing rules transmitted from the first device to the second device per unit time;
• and
• an average transmission delay time of the packet according to the number of the traffic processing rules.

A second device which processes traffic together with a first device in a communication system, the second device comprising:

• a transceiver to transmit and receive a signal;
• and
• a controller coupled to the transceiver,
• wherein the controller is configured to:
• measure a packet transmission rate and a packet transmission delay time of the second device per unit time, and
• deliver, to the first device, measurement information including a measurement value of the packet transmission rate and the packet transmission delay time measured per the unit time, the measurement information being used to determine whether to update a traffic processing rule by the first device,
• receive, from the first device, information related to the traffic processing rule determined based on the measurement information,
• update the traffic processing rule based on the information related to the traffic processing rule,
• process first traffic related to the updated traffic processing rule in case of receiving the first traffic, and
• deliver, to the first device, second traffic that is not related to the updated traffic processing rule in case of receiving the second traffic.
