Reliability Class (PDP 
Subscription) 

Reliability class associated with the PDP subscription. It considers reliability 
attributes such as delivery order, traffic handling priority, as well as allocation and 
retention priority. For example reliability class for PDP subscription can be 
unacknowledged GTP, LLC, acknowledged RLC or protected data. 

Delay Class (PDP 
Subscription)  

Defined category of network transient delay for the PDP subscription data. For 
example class 4. 

Precedence Class (PDP 
Subscription) 

 Service precedence delay supported by SGSN by discarding or allowing packets 
based on the precedence class for the PDP subscription. For example the precedence 
class for PDP subscription can be high priority. 

 Peak Throughput (PDP 
Subscription) 

Configured maximum allowed throughput rate for the PDP subscription. Along with 
other fields such as reliability, delay or precedence class, it can be used for traffic 
shaping. 

Mean Throughput (PDP 
Subscription) 

Configured mean throughput rate for the PDP subscription. Along with other fields 
such as reliability, delay or precedence class, it can be used for traffic shaping. 

Allocation/Retention 
Priority (PDP 
Subscription) 

Allocation, retention priority indicates the reliability of the PDP subscription data. For 
example for various traffic classes such as conversational, streaming, interactive and 
background, this priority can be defined as 1 or 2 or 3. 

Delivery of Erroneous 
SDUs (PDP 
Subscription) 

Status of the delivery of erroneous Service Delivery Units (SDUs) for the PDP 
subscription. For example it indicates whether the delivery of erroneous SDU’s is 
detected or not. 

Traffic Class (PDP 
Subscription) 

 Category of traffic associated with this PDP subscription. Traffic is broadly 
categorized as Conversational, streaming, Background and Interactive. 

Max SDU Size (PDP 
Subscription) 

Maximum allowable size of Service Data Units (SDUs) in octets, which is associated 
with this PDP subscription data. 

Max Bit Rate Uplink 
(PDP Subscription) 

Maximum allowable rate in kbps for sending that data from an MS to network, that is 
associated with the PDP subscription.Indicates maximum allowable rate in kbps for 
sending that data from an MS to network, that is associated with the PDP 
subscription. 

Max Bit Rate Downlink 
(PDP Subscription) 

Maximum allowable rate in kbps for sending the data from network to the MS, which 
is associated with the PDP subscription. 

Residual Bit Error Rate 
(PDP Subscription) 

Reliability based on residual Bit Error Rate (BER) associated with PDP subscription. 
For specific traffic class such as conversational, streaming, interactive or background, 
certain range of resudial BER is required. 

SDU Error Rate (PDP 
Subscription) 

Reliability class based on Service Delivery Unit (SDU) error rate associated with the 
PDP subscription. For specific traffic class such as Conversational, Streaming, 
Interactive or background, certain range of SDU error rate is required.
