COPYRIGHT © 2012 ALCATEL-LUCENT. ALL RIGHTS RESERVED.8
The Key Role of the SGW and PGW is to manage the User plane bearer traffic
• Note the 2 IP headers:
• Inner IP header from the UE going transparent through EPS
• Outer IP header to encapsulate GTP-U and is used inside the EPS

• Diameter is a AAA protocol
• It defines clients, servers, relays, and proxies
• Runs over TCP or SCTP using port 3868
• Base protocol is defined in RFC 3588 (2003)
• Defined as part of the base protocol are a number of messages and AVPs
• AVP = Attribute Value Pair (similar to a TLV)

DIAMETER PROTOCOL AND APPLICATIONS
COPYRIGHT © 2012 ALCATEL-LUCENT. ALL RIGHTS RESERVED.9
• Capability negotiation, i.e., which applications are supported• The Diameter protocol is used by Diameter applications. Each one defines its
own messages and AVPs on top of the base protocol
• NASREQ (authentication of users)
• Credit Control defined in RFC 4006 (prepaid accounting)• Gx, Rx
• Destination Realm (AVP) identifies the Diameter server
• Routing at relays/proxies: based on destination realm and application

• UE sends Attach message to MME to register with the network for service access
• MME will signal the SGW via a Create Default Bearer Request message to establish thedefault bearer after successful authentication
• SGW forwards the request to PGW
• PGW requests from the PCRF the new session policy then installs necessary filter for thenew session

QOS IN LTE NETWORKS
KEY BEARER / AGGREGATE ATTRIBUTES
• QoS Class Identifier (QCI)- Used to identify the traffic class of a specific bearer
• Allocation and Retention Priority (ARP)- The primary purpose or ARP is to decide if a bearer establishment/modification request
can be accepted or rejected in case or resource limitation
• Guaranteed Bit Rate (GBR) and Maximum Bit Rate (MBR)
COPYRIGHT © 2012 ALCATEL-LUCENT. ALL RIGHTS RESERVED.28
- GBR bearers are assigned a guaranteed rate and a maximum rate• APN Aggregate Maximum Bit Rate (APN-AMBR)- Aggregate rate for the total traffic of a UE’s Non-GBR bearers on a given APN
- Enforced by the PGW on Downlink and the UE on Uplink
• UE Aggregate Maximum Bit Rate (UE-AMBR)- Aggregate rate for the total traffic generated by a UE across all APNs
- Enforced by the eNodeB on Uplink

SDFs AND QOS MANAGEMENT
• The SGW and PGW need to support fine-granularity of QoS andcharging enforcement functions beyond transport / bearer level
- Multiple Service Data Flow (SDF) can be aggregated onto a single bearer- Uplink (UL) and Downlink (DL) packet filters are defined for each bearers
and QoS enforcements (policing, shaping, scheduling, etc.) are applied

• Relevant data according to procedure,
RF information• Radio quality: Channel Quality Indicator, dropped packets at RLC layer
• UE measurements: RSRP, RSRQ, etc.
• Round Trip Delay (RTD)
• RF measurement of other cells for HO preparation
A PCMD record is generated for each procedure that is executed for a particular UE.
A PCMD record is a semi-colon separated set of about 200 fields (grows with each release) containing data of interest for
that procedure. The actual structure is different from the figure.
