Method and apparatus for securing quality of service of data communication
First Claim
1. A method of securing a quality of service (QoS) of data being received by a mobile terminal at a data reception side that performs a handover from a first network to a second network, the method comprising:
- generating, at the mobile terminal at the data reception side, a first packet including information about the second network;
transmitting the first packet from the mobile terminal at the data reception side to a data transmission side; and
selectively performing the handover, at the mobile terminal at the data reception side, based on response information included in a second packet received from the data transmission side in response to the first packet,wherein the information about the second network includes information about a data transmission rate of the second network,wherein the first packet including the information about the second network is a real-time transport control protocol (RTCP) packet.

Abstract
A method and apparatus for securing a quality of service (QoS) of data communication is provided. The method of securing the QoS of data being received by a mobile terminal at a reception side that performs a handover from a first network to a second network comprises generating a packet including information about the second network, transmitting the packet to a transmission side, and selectively performing the handover according to whether a packet including information in response to the packet is received. When a reception side performs a handover, a transmission side can be informed of information about the second network via the exchange of packets between the reception side and the transmission side, thereby securing a QoS of the data transmission.
