Carrying Mobile Services from Small-Cell Base Stations
Because macro base stations provide uneven and inflexible coverage, small-cell base stations
featuring small sizes, light weights, and adaptation to any installation environments are used
together with macro base stations on mobile networks.
However, installation and deployment of small-cell base stations and their bearer equipment on
live networks encounter many difficulties because of their large quantity, wide distribution and
various installation environments. In addition, site selection, maintenance, and power supply
also encounter many difficulties.
In the Huawei mobile bearer solution, ATN 905 functions as bearer equipment for small-cell
base stations and benefits:
lAnywhere: ATN 905 is available in the indoor and outdoor types and can be installed in
various environments where small-cell base stations are installed.
lPlug-and-play: Plug-and-play enables NEs to automatically go online and implements
service provisioning in batches and remote commissioning in a centralized manner, thereby
improving the maintenance efficiency and reducing costs.
lPower over Ethernet (PoE): ATN 905 can supply power to small-cell base stations and
radio equipment over Ethernet electrical ports, requiring less space and contributing to
environmental protection.
Figure 1-1 shows networking of the mobile bearer solution to which ATN 905 belongs. As
bearer NEs for small-cell base stations, ATN 905s using a link topology are connected to access
NEs at the macro base station side and are extension of the ATN+CX IPRAN solution (IPRAN
is the abbreviated form of IP radio access network). This scheme enables E2E clocks and E2E
maintenance for the macro base station bearer solution. It is cost-effective, easy to deploy, and
easy to maintain.

NOTE
In the IPRAN macro base station backhaul network solution, ATN 905 is supported in the following modes:
lNative IP mode: If IPRAN uses a Layer 3 solution, such as, the hierarchy VPN (HVPN) solution, it is
recommended that ATN 905 connect to the IPRAN macro base station backhaul network in Native IP
mode, which facilitates deployment of end to end (E2E) Layer 3 IP connectivity and performance check
schemes.
lNative ETH: If IPRAN uses E2E Layer 2 solution or L2+L3 mixed VPN, it is recommended that ATN
905 connect to the IPRAN macro base station backhaul network in Native ETH mode, which facilitates
transparent transmission and processing of E2E Layer 2 VLAN packets.
Carrying Enterprise Leased Line Services
Generally, customer premises equipment (CPE) that bears enterprise leased line services
connects to a provider edge (PE) through optical fibers or a leased third-part network as shown
in Figure 1-2.
Figure 1-2 CPE directly connecting to a carrier network
A CPE is often far away from a PE. If a fault occurs, it is difficult to locate whether the fault
occurs on the optical fiber, leased network, enterprise network, or carrier network.

ATN 905 can be deployed as an Ethernet demarcation device (EDD) directly connected to CPE
and sharing the same equipment room with the CPE as shown in Figure 1-3. In this way, the
carrier network extends to the client side and the provider can manage the network between the
EDD and the PE.
Figure 1-3 CPE connecting to a carrier network through an EDD
In the Huawei enterprise service bearer solution, ATN 905 functioning as an EDD has the
following advantages:
lSupports IP forward performance monitoring (FPM), tests without requiring meters at sites,
quality of service (QoS), and quick fault sectionalization and location complying with RFC
2544.
–Supports 802.1Q in 802.1Q (QinQ) for separating user VLANs and carrier VLANs,
facilitating fault sectionalization.
–Supports dying gasp so that equipment reports an alarm when experiencing power
outage.
lSupport real-time performance management through periodical tests and statistics on E2E
service performance including the throughput, delay, and packet loss rate, service level
agreement (SLA) compliance reports.
Figure 1-4 and Figure 1-5 show basic networking of the enterprise service bearer solution to
which ATN 905 belongs.
lWith the help of the current IPRAN, ATN 905 can connect to the IPRAN macro base station
backhaul network. On the E2E ATN+CX network, enhanced ATN functions, such as DCN
plug and play and RFC 2544-compliant IP FPM, can be deployed to improve the network
operation and maintenance efficiency.
NOTE
In the IPRAN macro base station backhaul network solution, ATN 905 can also connect to the macro
base station backhaul network in Native IP or Native ETH mode.

destination port number, protocol
type, or other attributes. Traffic is
classified based on certain rules and
class-specific behaviors (traffic
control or resource allocation) are
performed on the traffic, enabling
class-based traffic policing, traffic
shaping, and congestion avoidance,
and providing differentiated service to
user services.
lSupports complex traffic
classification configuration in the

MAC address, destination MAC
address, ID of the protocol carried
at the link layer, VLAN, and
802.1p priority, which are carried
in Ethernet packet headers.
lClassifies traffic by IP priority/
DSCP/ToS value, source IP
address prefix, destination IP
address prefix, ID of the protocol
carried in IP packets,
fragmentation flag, TCPSYN flag,
TCP/UDP source port number or
port number range, and TCP/UDP
destination port number or port
number range, ICMP flag, and
time range flag, which are carried
with IPv4 packets.
lSupports implementing behaviors
on the classified traffic such as

Features and Functions Description
Traffic Policing CAR is mainly used for rate limit. In
the implementation of CAR, a token
bucket is used to measure the data
flows that pass through the interfaces
on a router so that only the packets
assigned with tokens can go through
the router in the specified time period.
In this manner, the rates of both
incoming and outgoing traffic are
controlled.
Queue Scheduling Supports PQ adn WFQ for queue
scheduling on interfaces. Maps
packets of different priorities to
different queues and adopts Round
Robin (RR) on each interface for
queue scheduling.
Congestion
Avoidance
Supports congestion avoidance.
Monitor the usage of network
resources (such as queues and buffers
in the memory) and discard packets
when the network congestion
intensifies to avoid network overload
by adjusting network traffic.
Random Early Detection (RED) or
Weighted Random Early Detection
(WRED) algorithms are frequently
used in congestion avoidance.
HQoS lProvides three levels of scheduling
modes to ensure diverse services.
lSets parameters such as WRED,
low delay, SP/WFQ, CBS, PBS,
and statistics function for each
queue.
lSets parameters such as the CIR,
PIR, number of queues, and
algorithm for scheduling queues
for each user.
lSupports HQoS in the L3VPN
scenario.
lSupports interface-based and
VLAN-based HQoS.
QoS for Ethernet Performs simple traffic classification
according to the 802.1p field in VLAN
packets.
