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)

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
