INTERACTION BETWEEN WCDMA PROTOCOLS, MAPPING OF CHANNELS

****Control Plane functions such as:

** Service Manager

co-ordinates the functions of the control plane for establishing, modifying and maintaining the service it is responsible for

provides all user plane QoS management functions with the relevant attributes

**Translation function

converts between the internal service primitives for UMTS bearer service control and the various protocols for service control of interfacing external networks

translation includes the converting between UMTS bearer service attributes and QoS parameters of the external networks service control protocol

**Admission/Capability Control

maintains information about all available resources allocated to UMTS bearer services

determines for each UMTS bearer service request or modification whether the required resources can be provided reserves these resources if allocated to the UMTS bearer service

checks also the capability of the network to provide the requested service

resource control performed by the admission control supports also the service retention

** Subscription Control

checks the administrative rights of the UMTS bearer service user to use the requested service with the specified QoS attributes.

**** User Plane Functions

** Mapping function

provides each data unit with the specific marking required to receive the intended QoS at the transfer by a bearer service.

** Classification function

assigns data units to the established services of a MT according to the related QoS attributes if the MT has multiple UMTS bearer services established.

** Resource Manager

distributes the available resources between all services sharing the same resource according to the required

** Traffic conditioner

provides conformance between the negotiated QoS for a service and the data unit traffic. Traffic conditioning is performed by policing or by traffic shaping. The policing function compares the data unit traffic with the related QoS attributes. Data units not matching the relevant attributes will be dropped or marked as not matching, for preferential dropping in case of congestion.

Note, there are more details discussed later in the presentation’

Transport Network Vertical Planes

TNVP have two parts:

Part I : Transport Network Control Plane : Makes it possible for the Application protocol in the Radio Network Layer (RANAP, RNSAP, or NBAP) to be independent of the technology selected for the data bearer in the user plane.

Part II : Transport Network User Plane : User plane => Data bearer(s),
Control Plane => Signaling bearer(s)
