UE 4Few LTE Acronyms
LTE Acronyms Meaning
Access Point Name Identifies an IP packet data network (PDN) and service
(APN) type provided by the PDN to that user’s session.
PDN Connection The Association between an mobile user and PDN
(APN). This is represented by one IPv4 Address and/or
one IPv6 Prefix
GPRS Tunneling Signaling and Tunneling protocol for data (between
P Pr ro otto oco coll ( (G GT TP P) ) e eN NB B,, S SG GW W,, a an nd d P PG GW W) )
EPS Bearer An EPS bearer uniquely identifies traffic flows that
receive a common QoS treatment between UE and
PDN-GW
Default Bearer First one to get established and remains established
throughout the lifetime of PDN Connection.
Dedicated Bearer Additional bearer(other than default), created for a PDN
connection to provide specific QoS treatment for Apps
Presentation_ID © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential
5Transport Traffic – Control
 Provide user authentication, establish data sessions
 Network Layer - IPv4, Dual stack or native IPv6
 Transport - Radio Access Network & Mobile Backhaul
Presentation_ID © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential
6Transport Traffic - Bearer
Two way user traffic between Users and Applications
 Encapsulated in tunnel (GTP)
 Default Bearer and Dedicated Bearer(s) if Required
 Service Level QoS
Presentation_ID © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential
7Transport Traffic - Bearer setup for Subscriber
Prior to 3GPP Rel-8 (LTE introduced from Rel-8 onward)
 Dual-stack User sends two PDP requests- One of for IPv4 and another for IPv6
 Gateway creates two unique PDP-contexts- One for IPv4 and another for IPv6.
Dual stack

3GPP Rel-8 onward
 Dual stack User send one PDP request “IPv4v6”
 Gateway will create bearer; Allocate IPv4 & IPv6 to same bearer
 For GPRS network single bearer is applicable from 3GPP Rel-9 onward
Dual stack

13IPv6 Planning Design Considerations
 Greenfield LTE deployments should be IPv6
 Dual Stack Users. Chose IPv6 as preferred
 Transport – Dual stack (Preference) or 6PE, 6VPE
 All LTE Gateway interfaces should be IPv6
 Internal Apps (i.e. IMS, Video etc.) should be IPv6
 NAT64 for IPv4 internet
 D De ep pllo oy yiin ng g L LT TE E iin n e ex xiis st tiin ng g n ne et tw wo or rk k
 Build LTE/EPS architecture with dual stack
 Integrate with existing 2.5/3G network on IPv4
 Dual stack UE, Gateway supporting dual stack
 Transport – 6PE, 6VPE or dual stack (without adverse impact)
 Create Services islands- served by IPv4, IPv6
 NAT64 for IPv4 internet

14IPv6 Subnet Considerations for Infrastructure
Infrastructure subnets typically not announced to internet
Summarization – optimize routing and easy to scale
Interface address- Choices - /126, /127, /64
Loopback /128
Subnetting Example (Assuming - /32 for Infrastructure)

/16 /32 /48 /64
Interface ID
Regions (/40 256 regions)
Functions within region (/48 provides 256 functions)
(eNodeB, IP-BH, MPLS Core, MME, HSS, SGW, PGW,
Datacenter, Security etc.)
Devices and subnets for each devices
(48 – 64 provides 65,000 subnet of /64)
Presentation_ID © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential
15IPv6 Subnet Considerations for Subscribers
LTE Users IPv6 subnets are announced to internet
 Separate block for each service i.e. APN/virtual APN
 Allocation strategy – Local Pool, AAA, DHCPv6
 Subnet strategy – Ability to identify services, easy growth

Regions (/40 256 regions)

Devices and subnets for each devices **
(48 – 64 provides 65K users within each service/APN)
** For wireless routers gateway allocated smaller block i.e. /60, /56 etc.
