4 High Level Requirements for End-to-End IP QoS

23.2073GPPEnd-to-end Quality of Service (QoS) concept and architectureRelease 17TS

4.1 End-to-End QoS Negotiation Requirements

– The UMTS QoS negotiation mechanisms used for providing end-to-end QoS shall be backward compatible with UMTS Release 1999.

– The UMTS QoS negotiation mechanisms used for providing end-to-end QoS shall not make any assumptions about the situation in external networks which are not within the scope of 3GPP specifications.

– The UMTS QoS negotiation mechanisms used for providing end-to-end QoS shall not make any assumptions about application layer signalling protocols.

– No changes to non-UMTS specific QoS negotiation mechanisms.

– The UMTS QoS negotiation mechanisms used for providing end-to-end QoS shall not make any assumptions about applications which may be used on terminal equipment attached to mobile terminals.

– Unnecessary signalling complexity and processing complexity in the network elements as well as the mobile terminal shall be avoided.

– Unnecessary signalling traffic due to end-to-end QoS negotiation shall be avoided.

– Methods for user authentication as well as billing and charging mechanisms related to the end-to-end QoS negotiation shall be kept as simple as possible.

– Minimum changes to network architecture and mechanisms due to introduction of end-to-end QoS negotiation.

– It shall be possible for an application on the external device to request end-to-end QoS.

4.2 QoS Policy Requirements

– The UMTS policy mechanisms described in TS 23.060 [19] shall be used for control of the UMTS bearers.

– Interaction between UMTS bearer services and IP bearer services shall only occur at the translation function in the UE and GGSN.
