Unified Quality of Service Negotiation Method Cross Multi-Media

1 . A method of unified quality of service (QoS) negotiation cross multi-media for a first unified terminal device (UTD) using a first medium for communication in a network system, the method comprising:

obtaining a QoS requirement from the first UTD;

via the first medium, transmitting a QoS negotiation request including the QoS requirement to a second UTD using a second medium for communication in the network system; and

when a QoS negotiation response corresponding to the QoS negotiation request is received from the second UTD, reporting a QoS negotiation result to the first UTD according to the QoS negotiation response.

2 . The method of claim 1 , wherein when the QoS negotiation response corresponding to the QoS negotiation request is received from the second UTD, reporting the QoS negotiation result to the first UTD according to the QoS negotiation response comprises:

when a QoS negotiation response success of the QoS negotiation response is received from the second UTD, reporting to the user or application the QoS negotiation is successful; and

when the QoS negotiation response failure of the QoS negotiation response is received from the second UTD, reporting to the user or application the QoS negotiation is failed.

3 . The method of claim 1 , further comprising:

configuring QoS parameters of the first UTD when a QoS negotiation response success of the QoS negotiation response is received from the second UTD.

4 . The method of claim 1 , further comprising:

when no QoS negotiation response is received from the second UTD during a period of time, reporting to the user or the application the QoS negotiation is failed.

5 . A method of unified quality of service, hereafter called QoS, negotiation cross multi-media for a first unified terminal device (UTD) compatible of at least a medium for communication in a network system, the method comprising:

via a first medium of the at least a medium, receiving a QoS negotiation request including QoS requirement from a second UTD of the network system to a third UTD of the network system;

checking whether the QoS requirement is acceptable for the first medium;

via second medium of the at least a medium, forwarding the QoS negotiation request to the third UTD when the QoS requirement is acceptable for the first medium; and

transmitting a QoS negotiation response failure to the second UTD when the QoS requirement is not acceptable for the first medium.

6 . The method of claim 5 , further comprising:

receiving a QoS negotiation response corresponding to the QoS negotiation request, from the third UTD; and

forwarding a QoS negotiation result to the second UTD according to the QoS negotiation response.

7 . The method of claim 6 , wherein receiving the QoS negotiation response from the third UTD comprises:

receiving a QoS negotiation response success of the QoS negotiation response from the third UTD when the QoS requirement is acceptable for the second medium; and

receiving a QoS negotiation response failure of the QoS negotiation response from the third UTD when the QoS requirement is not acceptable for the second medium.

8 . The method of claim 6 , wherein forwarding the QoS negotiation result to the second UTD according to the QoS negotiation response comprises:

forwarding the QoS negotiation response success to the second UTD when the QoS negotiation response success is received; and

forwarding the QoS negotiation response failure to the second UTD when the QoS negotiation response failure is received.

9 . The method of claim 7 , further comprising:

configuring QoS parameters of the first UTD when the QoS negotiation response success is received.

10 . A method of unified quality of service, hereafter called QoS, negotiation cross multi-media for a first unified terminal device (UTD) using a first medium for communication in a network system, the method comprising:

via a first medium, receiving a QoS negotiation request including QoS requirement from a second UTD of the network system;

determining whether the QoS requirement is acceptable for the first medium; and

transmitting a QoS negotiation response to the second UTD according to the determination.

11 . The method of claim 10 , wherein transmitting the QoS negotiation response to the second UTD according to the determination comprises:

transmitting a QoS negotiation response failure of the QoS negotiation response to the second UTD when determining the QoS requirement is not acceptable for the first medium; and

transmitting a QoS negotiation response success of the QoS negotiation response to the second UTD when determining the QoS requirement is acceptable for the first medium.

12 . The method of claim 11 , further comprising:

configuring QoS parameters of the first UTD when determining the QoS requirement is acceptable for the first medium.
