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 reception side that performs a handover from a first network to a second network, the method comprising:
- 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.

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.

23. A method of securing a quality of service (QoS) when a mobile terminal moves between service areas provided two wireless communication networks having a switch system and different data transmission rates, comprising:
-
detecting, at the mobile terminal, a handover from the first network to the second network, when the mobile terminal moves from a service area provided by a first network to a service area provided by a second network,; generating, at the mobile terminal, a packet including information about the second network; transmitting, at the mobile terminal, the packet including information about the second network to the switch system; and selectively performing, at the mobile terminal, the handover from the first network to the second network upon receipt of a packet including response information from the switch system. - View Dependent Claims (24, 25, 26)
