  PDN Gateway Overview 

Features and Functionality - Base Software  ▀   

 

Cisco ASR 5x00 Packet Data Network Gateway Administration Guide  ▄

optionally share or mirror a single quota database so as to support Gy session failover from one server to the other. For a 
more scalable installation, a layer of proxies or other Diameter agents can be introduced to provide features such as 
multi-path message routing or message and session redirection features. 

The Cisco implementation is based on the following standards: 

 

RFC 4006 generic DCCA, including: 

 

CCR Initial, Update, and Final signaling 

 

ASR and RAR asynchronous DCCA server messages 

 

Time, Total-Octets, and Service-Specific-Units quota management 

 

Multiple independent quotas using Multiple-Services-Credit-Control 

 

Rating-Group for quota-to-traffic association 

 

CC-Failure-Handling and CC-Session-Failover features 

 

Final-Unit-Action TERMINATE behavior 

 

Tariff-Time-Change feature. 

 

3GPP TS 32.299 online mode “Gy” DCCA, including: 

 

Final-Unit-Action REDIRECT behavior 

 

Quota-Holding-Time: This defines a user traffic idle time, on a per category basis, after which the usage 

is returned and no new quota is explicitly requested 

 

Quota-Thresholds: These AVPs define a low value watermark at which new quota will be sought before 

the quota is entirely gone; the intent is to limit interruption of user traffic. 

These AVPs exist for all quota flavors, for example “Time-Quota-Threshold”. 

 

Trigger-Type: This AVP defines a set of events which will induce a re-authentication of the current 

session and its quota categories. 

Gn/Gp Handoff Support 

In LTE deployments, smooth handover support is required between 3G/2G and LTE networks, and Evolved Packet 
Core (EPC) is designed to be a common packet core for different access technologies. P-GW supports handovers as user 
equipment (UE) moves across different access technologies. 

Cisco's P-GW supports inter-technology mobility handover between 4G and 3G/2G access. Interworking is supported 
between the 4G and 2G/3G SGSNs, which provide only Gn and Gp interfaces but no S3, S4 or S5/S8 interfaces. These 
Gn/Gp SGSNs provide no functionality introduced specifically for the evolved packet system (EPS) or for 
interoperation with the E-UTRAN. These handovers are supported only with a GTP-based S5/S8 and P-GW supports 
handoffs between GTPv2 based S5/S8 and GTPv1 based Gn/Gp tunneled connections. In this scenario, the P-GW works 
as an IP anchor for the EPC. 

Important:

 

 

To support the seamless handover of a session between GGSN and P-GW, the two independent 

services must be co-located on the same node and configured within the same context for optimum interoperation. 

Important:

 

 

For more information on Gn/GP handoffs, refer to 

Gn/Gp GGSN/SGSN (GERAN/UTRAN)

 in the 

Supported Logical Network Interfaces (Reference Points)

 section in this chapter.
