As to the multi-mode UE, the common anchoring point should be selected to ensure there is no P-GW/GGSN
relocation when the UE moves from the legacy PS core to LTE. That demands that the GGSN/PGW must be
convergent for seamless handover between GU and LTE network.

Operators Current Situation and Challenges
Solution & Value
Background • Investing in more infrastructure to increase the
offered bandwidth is not a suitable policy anymore,
if there is no bandwidth management policies are
deployed in the network..
• These bandwidth management control policies
should be based on subscriber category,
geographic location, date and time, application
used, network type and/or network congestion
conditions.
• Churn could increase (VIP subscribers) due to poor
customer experience.,
• No data monetization based on use and
application.
• This along with the risk of losing VIP subscribers
will affect negatively the ARPU.

Solution
Wireless Optimization Based on FPI
E2E Resource optimization: PCRF/PCEF – rule preparation; PCEF – service identification & FPI delivery; RAN – schedule by FPI
For GPRS/UMTS network, FPI is mapped as DSCP (differentiated services code point) in IP packet and delivered to SGSN or RAN.
For LTE network, FPI is mapped into GTP-U extension header and delivered to eNodeB.
Private protocol for transferring data flows on the RAN and CN, but Huawei already presented it to 3GPP specifications.
Innovative bandwidth optimization solutions save radio resource & improve service quality

Wireless Optimization Based on Cell Load
E2E Resource optimization (UL): RNC/eNodeB – monitor & report cell status; PCEF/PCRF – policy control based on cell load
When the cell status changes, the RAN side reports the congestion level to the GGSN/P-GW using GTP-U extension headers. The GGSN/P-GW reports the congestion level to the policy center (PCRF or PCEF). (Huawei private protocol)

• IPv6 service
island emerging
• Dual stack Bearer &
PDP context support
• IPv4 & IPv6 support
on Gi/SGi
Phase I
Step 2
• IPv6 only terminal
emerging
• Charging and
PCC control for
IPv6 service
• Enable IPv6 DPI
• Gx/Gy IPv6 support
• External NAT64 for
V6 terminal access
to V4 service.
• 2/3/4G interworking
Phase II
• PS IP backbone
and backhaul
need be rebuild to
pure IPv6 network
• IPv6 networking
capability for IP
backbone or

TCP Optimization PS10.0 13Q4
• By monitoring the TCP window size and RTT between the UE and
SP Application server, UGW can adjust the TCP window size
(using TCP proxy mechanism) to optimize the overall E2E
transmission rate.
• TCP Optimization can be flexible enabled for different scenarios: user
priority, service type, network status, RAT type
Solution
• Improve user experience with higher TCP throughputs
• Flexible policy may be defined for valuable user and service, not whole
traffic.

Un-trusted WiFi Access Procedure
• Step 0: UE performs WLAN network association and gets local IP from it
• Step 1: UE selects ePDG and triggers IKEv2/EAP-AKA towards ePDG
› EAP-AKA authentication during IKEv2 procedure is used to authenticate UE and negotiate ciphering key
› UE IMSI and APN are sent to ePDG during IKEv2 procedure
› TTG/eDPG obtains UE IMSI/MSISDN from AAA after successful auth
• Step 2: ePDG setup GTP tunnel with PGW, during which PGW allocates remote IP to UE
• Step 3: IKEv2 procedure is finished while UE obtains remote IP
