Components Definition / Details

APN (Access Point Name) Access po in t name (APN) identifies an IP packet data network (PDN), that amobile data user wants to communicate with.

In addition to identifying a PDN, an APN may also be used to define the type ofservice , (eg connection to wireless application protocol (WAP) server,

multimedia messaging service (MMS)), that is provided by the PDN. the P-GW deduces from local confi uration data associated with the APN:

The source of IPv6 Prefixes (P-GW internal prefix pool, or external addressallocation server);

Any server(s) to be used for address allocation, authentication and/or protocol. . ,

24.229 [47]); The protocol, i.e. RADIUS, Diameter or DHCPv6, to be used with the

server(s);

- w

IP-CAN Bearer IP transmission path of defined capacity, delay and loss rate.

Service-Data-Flow (SDF) An aggregate set of packet flows that matches a service data flow template.e au earer e earer w c s rs es a s e or a new connec on an

remains established throughout the lifetime of the PDN connection Always a non-GBR bearer

Dedicated Bearer Additional EPS Bearer that may be activated for a PDN connection

SGW/PGW Role

Entity Role Specifications

SGW (Serving-GW) terminates the interface towards EUTRAN

The local Mobility Anchor point for inter-eNB handover Mobility anchoring for inter-3GPP mobility (terminating S4 and relaying the

traffic between 2G/3G system and PDN Gateway). This is sometimesre erre o as e nc or unc on

EUTRAN idle mode downlink packet buffering and initiation of networktriggered service request procedure

Lawful Interception

Packet routing and forwardingPGW (PDN-GW) terminates the SGi interface towards the PDN.

Functions include: Mobility anchor for mobility between 3GPP access systems and non-3GPP

access systems. This is sometimes referred to as the SAE Anchor function

Policy enforcement- . . Charging support Lawful Interception UE IP address allocation
