1 Product Positioning and Features

1.1 Product Positioning This document is released with the eWBB2.0 Solution. The version of the product corresponds to UGW9811 V900R009C01.

eWBB2.0 UGW9811, developed by Huawei, is intended for use on the evolved packet core (EPC) system only. In this document, eWBB2.0 UGW9811 is abbreviated as UGW9811.

The UGW9811 combines the functions of a serving gateway (S-GW) and a PDN gateway (P-GW).

1.1.1 3GPP System Architecture Evolution This section describes architectural evolution of the 3rd Generation Partnership Project (3GPP) EPC system.

Introduction to current networks Wireless technology has undergone a process of development from the Global System for Mobile Communications (GSM, 2G) to the General Packet Radio Service (GPRS, 2.5G) and then to the Universal Mobile Telecommunications System (UMTS, 3G). Currently, mobile communications have achieved almost universal coverage, with high-speed wireless data transmission, and easy access to the Internet. Mobile communications are now providing multimedia services, such as voice, data, and video, enabling people to communicate with each other anywhere anytime.

The structures of current networks, however, cannot keep pace with the rapid development and diversified service requirements. The following issues are major limitations to the current network structure:

l The packet switched (PS) domain only supports non-real-time services and the circuit switched (CS) domain is responsible for implementing voice services. This scheme means that carriers must deploy PS and CS domains separately, which complicates network management and maintenance and increases operational expenditure (OPEX).

l Data routing and forwarding efficiency is low because of multiple network layers. l Data processing capabilities and radio access technologies (RATs) of mobile stations

(MSs) on current networks have been continuously improving, calling for the convergence of existing RATs and support for diverse wireless networks.

Introduction to the EPC network To strengthen the network competitiveness, 3GPP has been developing enhanced 3G (E3G).

l The E3G air interface technology is Long Term Evolution (LTE). l The LTE core network is system architecture evolution (SAE), also called EPC.

3GPP EPC aims at exploring key communication technologies in the next 10 years. The 3GPP EPC has the following key features:

l All-IP network: The CS domain no longer exists on EPC networks. Voice services will be provided by PS domains and IP multimedia subsystem (IMS) networks. The all-IP network structure will improve network efficiency and performance.

l Flat network: The optional co-design of serving gateway (S-GW) and PDN gateway (P-GW) is supported, providing simplified network deployment and reduced latency.

l Multiple RATs: The 3GPP EPC system can interwork with existing 3GPP systems. It also supports non-3GPP access, and roaming and handovers between 3GPP systems and non-3GPP systems.

l High data rate: The peak uplink rate is 50 Mbit/s and the peak downlink rate is 100 Mbit/s.

l Fast deployment: The EPC network can be quickly deployed owing to its simple network structure, to meet the increasingly diversified service requirements.

l Enhanced real-time services: The latency in service connection setup is reduced.

The EPC network is intended to provide high-speed packet data services. It has a less complex network structure than current core networks, with the following differences:

l The eNodeB can access the EPC network directly. RNC functions are integrated into the eNodeB.

l The functions of the network elements (NEs) in the PS domain are adjusted as follows: − The SGSN signaling plane and forwarding plane are separated. The MME

implements the function of the SGSN signaling plane and the S-GW implements the function of the SGSN forwarding plane.

− The P-GW functions as the GGSN. − The optional co-design of S-GW and P-GW is supported.

l The EPC network allows multiple RATs, including non-3GPP access technologies such as CDMA2000 high rate packet data (HRPD). See Figure 1-2.

1.1.2 Huawei EPC Solution The EPC solution provided by Huawei meets diverse service and access requirements.

UGW9811 located in EPC(Evolved Packet Core) supports the functions and any combination of S-GW and P-GW.

The EPC network primarily consists of the following elements:

l User equipment (UE): initiates and receives calls over air interfaces. l Evolved UMTS terrestrial radio access network (E-UTRAN): implements all functions

related to the radio access. l EPC: core of the EPC network, which consists of the MME, S-GW, P-GW, and HSS, and

connects the EPC network to external packet data networks (PDNs) such as the Internet.

1.1.3 NE Functions The functions of the major NEs in the EPC solution are as follows.

E-UTRAN E-UTRAN implements all functions related to the radio access:

l Establishes and manages radio resources. l Compresses packet headers and encrypts user plane data. l Selects an MME when no MME can be identified based on information provided by

UEs. l Implements uplink bearer-level rates based on the UE aggregate maximum bit rate

(AMBR) by using uplink scheduling and maximum bit rate (MBR). l Implements downlink bearer-level rates based on the UE-AMBR. l Controls uplink and downlink data access.

l Marks uplink packets with differentiated services code points (DSCPs) based on QoS class identifiers (QCIs).

MME The MME is responsible for mobility management (context management and mobility status management) of the control plane, and allocates temporary mobile subscriber identities (TMSIs). The MME implements the following functions:

l Processes non-access stratum (NAS) signaling. l Secures NAS signaling l Manages the reachability of UEs in ECM-IDLE mode, including controlling and

implementing paging retransmissions. l Manages tracking area lists. l Selects a P-GW and S-GW. l Selects an MME upon an inter-MME handover l Performs authentication. l Implements bearer management, including the establishment of dedicated bearers. l Performs lawful interception over signaling services.

S-GW The S-GW provides gateway functions for the EPC network and provides interfaces to the E-UTRAN.

The S-GW implements the following functions:

l Serves as a local mobility anchor (LMA) for inter-eNodeB handovers. l Helps the eNodeB with reordering during an inter-eNodeB handover by sending one or

more end markers to the source eNodeB. l Buffers downlink data packets for UEs in ECM-IDLE mode and triggers paging to an

E-UTRAN. l Routes and forwards packets. l Marks uplink and downlink data packets with DSCPs. l Supports subscriber- or QCI-based charging across systems of different carriers.

P-GW The P-GW is a user-plane mobility anchor between 3GPP networks and non-3GPP networks, and connects UEs to external PDNs. It provides gateway functions for the EPC network and provides SGi interfaces to the PDNs.

The P-GW implements the following functions:

l Performs subscriber-based packet filtering using functions such as deep packet inspection (DPI).

l Assigns IP addresses for UEs. l Marks uplink and downlink data packets with DSCPs. l Charges uplink and downlink packets based on service data flows (SDFs) defined by the

policy and charging rules function (PCRF) or DPI policies that are configured on the P-GW.

l Static payload indicates the capability of the equipment in package to bear the pressure from the top in normal pile-up method.
