IPRAN Network High Level Design for Maroc Telecom

1 Introduction

1.1 ObjectivesBased on the customer requirement to migrate the ATM IUB interface to IPRAN network, high level design (HLD) is to reasonably design the UMTS RAN networking to establish an IP UTRAN network. The UTRAN network has the following features:

Using IP as the bearer on IUB interface for all 3G services

Being of good security, high reliability, and reasonable resource allocation

Supporting features extension

HLD focuses on Huawei RAN network elements (NEs) ,mainly NodeB and RNCs.

1.2 ScopesThis document involves HLD for the Maroc Telecom IPRAN.

According to the features of the Huawei UMTS product, HLD covers IPRAN networking migration, focusing on operation and maintenance (O&M), system clock synchronization, IPRAN resource distributed design, transmission interface capability, transmission interface networking reliability, interconnection negotiation, and common features.

2 UMTS Network

Structure

2.1 Existing URAN NetworkIub interface on existing UTRAN network is based on ATM over SDH networks, 19 RNCs and 1600 NodeB communicate each other through the TDM network,the RNC clock synchronizationis provided by IUCS interface, NodeBs use line clock extracted from IUB E1 links.

M2000 maintain RNCs by direct connection based on PPP over E1,all NodeB communicate with M2000 through RNCs, in other word the OM link of NodeB is carried over IUB.

Fig: Existing UTRAN Network Architecture

2.2 Target NetworkIn the targeted IPRAN network, Maroc Telecom requires to migrate from ATM to IP all de services carried on IUB interface.

The TDM E1s are maintained only for Clock synchronization in the first phase ,later on, SyncE and/or PTP synchronization will replace E1 .

IUCS,IUPS,IUR interfaces will not be changed.

4 Principles and

Information of IPRAN O&M Design

4.1 O&M Network TopologyM2000 manage and maintain NodeB directly through IP network without passing by RNC.

Fig: Topology of Target O&M network

4.2 O&M Networking Principle and Design

4.2.1 Existing O&M Network Topology

The RNC BAMs are connected to the local router using FE ,each RNC uses a.b.c.d/29 subnet.The RNC router is then connecter to Central OMC router in Sokarno using E1.Static routes are defined in RNC ,M2000 and on Both Local and central routers.

The NodeB communicate with M2000 through RNCs, which define internal routes between Iub interface and M2000.

4.2.3 O&M IP Planning DesignThe RNC OM Link will not be changed,

The NodeB is maintained by the M2000 or the maintenance terminal (including LMT) through the remote OM channel.

The recommended remote NodeB maintenance channel is over the IP link. IP data streams are terminated on the Iub interface board. Through IP routing, O&M packages are routed to the main control board of the NodeB for processing.

4.2.4 NodeB OM Channel Design

OMCH Policy

It is recommended that the NodeB is directly routed to the M2000 for maintenance without passing the RNC. This can separate service channels from maintenance channels, thus enhancing network security.

The OM packet are carried over the same VLAN 200,OM and other services on IPRAN are differentiated using QoS priority .

DSCP Design

The Differentiated Service is a method of providing different services with different transmission priorities.

All the IUB services are carried over a single VLAN, the priority policy are assured by layer 3 and layer 2 tagging:

3GPP Traffic TypePHB (Per Hop

OAM O&M AF41 34 4

The recommended OM DSCP is 34, at IEEE802.1p level the OM is tagged with priority 4,

OMCH Configuration

Route 1: On the NodeB side, configure a route to the M2000. The next hop is the interface IP address of the access Router to IPRAN.

Route 2: On the M2000, configure a route to the NodeB OMIP. The next hop is the interface IP address of the PE Router.

In addition, the routes of transmission equipment need to be configured.

OSPF is configured between OSS router and IP backbone

5 RAN System Clock

Synchronization Design

This chapter describes the system clock source design of the RNC and NodeB and flow directions of relevant system clocks.

5.1 RNC System Clock Source Design The RNC clock synchronization is provided by the STM1 link connecting the MGW to RNC.the RNC synchronization mode will not be changed after migration to IPRAN.

Fig: System clock stream of the RNC

5.2 NodeB System Clock Source DesignTow scenarios are supported by NodeB for clock synchronization:

16

Page 17: Hld Report Ipran Iam v2

IPRAN Network High Level Design for Maroc Telecom

The Iub interface uses currently the TDM transport: all NodeB are connected to RNC using E1, Therefore, it is recommended to set the NodeB to extract clock signals from the existing E1, or from any other transmission equipment able to provide 2Mhz input for the NodeB.

The NodeB supports also the IP clock synchronization, in this scenario; both SyncE and 1588v2 are supported by the BTS

E1 Clock Synchronization

• All service are based on metro IP network, no need for the E1 network for the clock

• The NodeB extract The clock using GE interface, the clock can be SyncE or 1588v2

• Clock source based on IP should be provided by IPRAN network

6 IPRAN Resource

Distributed Design

This chapter describes optimization design for RNC capabilities, involving board configuration, the port controller, NodeB allocation.

6.1.1 RNC Transmission Interface Boards Layout Design

The GOUa interface is the main GE interface of RNC,it s recommended to use 2 GOUa Board in load share mode to connect each RNC to IPRAN.The GOUa board performs the following functions:

Provides two channels over GE optical ports, which are used for IP transmission

Provides the Automatic Protection Switching (APS) function between the active and standby boards

Provides the routing-based backup and load sharing

7 RAN Transmission

Interface Capability Design

This chapter provides recommended transmission configurations on the control plane and user plane of each IUB over IP interface .

7.1 Iub Transmission Interface Capability DesignThis section describes how different services on IUB are mapped over IP transmission resources.

7.1.1 Traffic Mapping on IP Strategy DesignIP transport networking of the Iub interface indicates that the protocol (IP) stack networking is used between the RNC and the NodeB.

With the development of data services, especially the introduction of the HSDPA/HSUPA, the Iub interface has larger and larger requirements for transmission bandwidth. Introducing the IP transmission technology can save the cost.

22

Page 23: Hld Report Ipran Iam v2

IPRAN Network High Level Design for Maroc Telecom

IP transport Networking

IP transport can transmit the services of different QoS in different ways. Real time services have higher priority than HSPA services. the figure here below shows the IP transport networking.

Fig: IP transport networking

The Maroc Telecom RNC is configured with the IP interface board (GOUa). The IP interface board is connected to the IP transmission network through the GE port.

The NodeB is connected to the IP transmission networks through the corresponding IP interface boards.

Design for the Transmission Resource Mapping Table

The transmission resource mapping table (TRMMAP) shown in following table is designed according to Maroc Telecoms requirement and the transmission resource allocation.

The trend above shows the throutput of RNC Ainsebaa ( Iub interface including 144 NodeB),the peak required bandwidth for Iub is 300 Mbps, then the average of used Iub bandwidth per NodeB is 2 Mbps ,

Target IUB Throughput

Taking in consideration the expansion of the network and the introduction of new enhanced features, requirements in term of bandwidth are increased, therefore a model design of Iub is performed in order to respond to the future bandwidth demand.We admit the following assumption:

1) NodeB and RNC are both RAN112) HSPA+ 21 Mbps is activated (increase the traffic around 16% ) 3) Current bandwith is the the Physical Iub Bandwidth (7 Mbps)4) S222 is implemented in all hard ware (double the current traffic)5) No limitation in term of Hardware processing

Current Max bandwidhth :7 MbpsS222 Max Bandwidth ( x2): 14 Mbps

Hspa+ (+ 16%) = 16.24 Mbps

PS: the Model above is a theatrical one based on some assumption, an accurate model should take in account the Number of user per RNC and traffic model.

7.2 Iub Transmission Configuration Design for Typical NodeB

It s recommended to use 4 IPPATH in user plan to differentiate each service priority, for control plan NCP and CCP are assigned DSCP 48.

The Qos is assured according to layer 2 and layer 3 mapping (DSCP,VLAN priority)

Transmission Interface Reliability Design

This chapter describes the reliability design of transmission interfaces, including the network topology of the Iub, redundancy of interface boards and ports, failure detection, QoS, transmission security design, and address allocation. This can ensure reliable and secure transmission, detect failures in time, and differentiate priorities to guarantee high-priority services.

8.1 Iub Transmission Interface Networking Reliability Design

8.1.1 Iub Networking Topology

Fig: Iub networking

The Iub interface uses the IP transmission and supports IP protocol stacks. Active and standby GOUa boards provide GE port to connect two CEX Routers ,the GOUa corresponding ports are configured in load share. Therefore The RNC provide 2 interface IP and one logical IP for communication. In NodeB side, one GE port is used to support connection.

The load sharing is assured by configuring 2 routes for each NodeB with different priority (high & low),

26

Page 27: Hld Report Ipran Iam v2

IPRAN Network High Level Design for Maroc Telecom

One of them pass through the active GOU the second one pass through standby one. the NodeBs are balanced in both GOU, in other Word 50% of NodeB High priority Routes is over active GOU, and the rest NodeB high priority routes are over standby GOU.

8.1.2 Iub Interface Boards Redundancy Design

Board Redundancy Principle

In the case of board backup, one board is active and the other is standby. When the active board is faulty, switchover occurs and the standby board serves as active board.

The processing capability of one pair of active and standby boards is equivalent to the processing capability of one active board.

Board backup can improve network reliability. Services can run normally so long as one of the active and standby boards works properly. In the case of non-redundancy, the failure of a board may interrupt network services.

Recommended Board Redundancy Mode

It is recommended that GOUa work in boards backup mode for the Iub interface.

8.1.3 Iub Transmission Ports Redundancy in RNC Design

GOUa Port Redundancy Principle

When a pair of GOUa boards work in the backup mode, the corresponding ports of the active and standby GOUa boards can be also in the backup mode, for example, port 0 of active board and port 0 of standby board. Board backup and port backup are independent,Thus GE ports can be both active while the related board are in active standby mode.

Recommended port Redundancy Mode

It is recommended that the 2 port are work in active in order to assure load sharing over Iub interface.

8.1.4 Iub Transmission Fault Detection DesignBFD detection can be used to detect gateway of RNC GE port connectivity according to RNC license.

8.1.5 Iub Transmission QoS Difference DesignIn terms of wireless network layers, the transmission network layers of the RNC and NodeB first map service priorities into the DiffServ PHB at the IP layer, mark the service priorities with different DSCPs, and then map the service priorities into the VLAN priority domain through the PHB. In addition, operators can flexibly configure the mapping between subscriber service priorities and IP QoS and the mapping between IP QoS and VLAN priorities according to the requirement.

Therefore, the QoS-related design covers the following three parts:

Transmission Resource mapping table for Iub, that is, the mapping between services and transmission resources (paths). It may use the default map for Iub IP.

8.1.6 Iub Transmission Layer Address Allocation Design

RNC IP Address Planning

In IP L3 (FE/GE) networking, it is recommended to use Ethernet IP address for each FE/GE port to connect to the transmission equipment, another device IP should be defined as logical IP for communication with NodeB.

RNC IPRAN

Fig: IP requirements of RNC

IP1_IP2/IP3_IP4 are used for interconnection with CEX Device

IP5_IP6 are logical IP used for communication with NodeB (Service and OM)

IP1/IP3/IP5 can not be in the same subnet

The segment 1 and 2 are provided according to IPRAN planning design

The segment 3 is designed by UTRAN, in addition, another 3 segment per RNC are reserved by

UTRAN for future migration to dynamic routing.

NodeB Address Planning

In IP L3 (FE/GE) networking, the address of a NodeB (ETHIP) must not be on the same network segment as the RNC interface board’s ETHIP and DEVIP.

Each NodeB needs one ETHIP and one OMIP.
