Uplink Direct transfer
UE → RG - UPLINK DIRECT TRANSFER
UE dedicated paging
RG → UE - PAGING TYPE 2
The uplink direct transfer procedure is used in the
uplink direction to carry all subsequent upper layer
(NAS) messages over the radio interface belonging to a
signalling connection.
This procedure is used to transmit dedicated paging
information to one UE in connected mode in
CELL_DCH or CELL_FACH state. Upper layers in
the network may request initiation of paging.
Radio bearer establishment
RG → UE - RADIO BEARER SETUP
UE → RG - RADIO BEARER SETUP COMPLETE
UE → RG - RADIO BEARER SETUP FAILURE
Radio bearer release
RG → UE - RADIO BEARER RELEASE
UE → RG - RADIO BEARER RELEASE
COMPLETE
UE → RG - RADIO BEARER RELEASE FAILURE
Cell update procedures
UE → RG - CELL UPDATE
RG → UE - CELL UPDATE CONFIRM
The cell update procedures serve several main
purposes:
• to notify the Network of an RLC unrecoverable
error [25.322] on an AM RLC entity;
• to be used as a supervision mechanism in the
CELL_FACH state by means of periodical update.
• to act on a radio link failure in the CELL_DCH
state;
The cell update procedures may:
• cause a state transition from the CELL_FACH
state to the CELL_DCH state or idle mode.
The cell update procedure may also include:
• a re-establish of AM RLC entities;
• a radio bearer release.
4.4 QoS Broker Software Specification
Table 16 : RRC procedures and messages
This section describes the software specification of the Bandwidth Broker (QoS Broker). It will describe
the Moby Dick components that interact with the QoS Broker, the broker’s interfaces and all its internal
functions.
On each QoS Broker interface we will discuss the messages exchanged between the QoS Broker and the
other MobyDick components, its format and when they will occur. At the end of the section we will
resent the QoS Broker databases format, and discuss its purpose.
A bandwidth broker is an entity that takes admission control decisions and configures all access network
components, according to a set of conditions given by administration entities.
4.4.1 General QoS Broker Positioning
Figure 70 shows a view of all the entities of the Moby Dick project that interact with QoSBroker.
