1 Scope
The present document, "TIPHON signalling and control of end-to-end Quality of Service (QoS)", specifies procedures
for the control of end-to-end QoS within and between domains. TS 101 882 (see bibliography) specifies the TIPHON
meta-protocols and object definitions required by these control procedures.
Additional annexes to the present document define profiles for mapping a number of existing candidates protocols to
the specified TIPHON meta-protocols.

4 End-to-end QoS Signalling functional requirements
4.1 Description
4.1.1 General description
End-to-end QoS Signalling is used within a TIPHON network to ensure that a caller is provided with an end-to-end
connection having at least the QoS class subscribed to or a lower QoS class if this is acceptable to the user. A QoS level
may either be requested explicitly by the user on a call-by-call basis or may be predefined as part of the user's
subscription. Additionally, the caller may be able to take specific actions if the QoS moves outside the accepted level
during an established call.
The user may use any of the following methods to request a specific end-to-end QoS at call establishment:
1) By subscription:
The agreement between the user and the user's service provider identifies the QoS level to be requested for any
call. The QoS level may be fixed or variable based upon such parameters as time-of-day and call destination.
This method requires no signalling between the user and the service provider at call setup time.

2) By the use of a standardized TIPHON QoS Class:
The user indicates at each call establishment which of the TIPHON QoS Classes (standardized in
TS 102 024-2 [4]) is to be requested for the call. The TIPHON QoS Classes are identified as:
- Class 1 Best effort;
- Class 2A Acceptable;
- Class 2M Medium;
- Class 2H High;
- Class 3 Best (broadband);
3) By the use of a non-standardized QoS Class:
The user indicates at each call establishment which non-standardized QoS class is to be requested for the call.
The QoS class may represent any combination of QoS parameters previously agreed between the user and the
service provider.
4.2 Procedures
4.2.1 Provision and withdrawal
End-to-end QoS Signalling shall be provided on a per-name, per application basis to all subscribers to the simple call
within a TIPHON system.
When establishing a call, a user shall be able to select at least one of the options identified in table 1.
