M-MGW FUNCTIONALITY The following items listed in Figure 1-9 are functions of the MMGW based on CPP: • AMR coding and decoding. The transcoder algorithms that are supported in the M-MGW conform to 3GPP Release 99. This includes the Adaptive Multi Rate (AMR). All modes of the AMR transcoder will be supported allowing the operator to choose which subset of these shall be used in their network. • Data Transmission Interworking Unit (DTI). The Data Transmission Interworking Unit provides a modem pool for circuit based data going to analog networks and also provides a connection to ISDN. • Echo Canceller. The Echo Canceller attenuates the echo generated at the conversion between 4-wire and 2-wire transmission in the PSTN. • Multiparty Call. Media stream functions support bridging multiparty calls. • Tone Sender/Receiver. Different tones (such as alerting, busy, and so on) are played and sent. • DTMF Sender/Receiver. Sends DTMF tones as requested by a mobile station and receives DTMF tones. • Announcement Machine. Informative messages on special conditions in the network or the service in use are played to the subscribers with this function. • Setup/release of user Circuit Switched data bearers. • Quality of Service (QoS) IP routing and switching. The MMGW supports ATM and IP transport. This includes AAL2 switching, for variable length cells, and a high capacity real-time IP router. The M-MGW also supports STM. In addition, the M-MGW contains up-to-the-minute web based element management and online documentation. • Data volume counting. For volume-based charging support, the M-MGW tracks the volume of data sent and received (for packet based services). This information is then provided to the SGSN-W server, over H.248, to be included in the Call Data Record (CDR). • Security for packet based traffic. IPSec function for secure transmission between packet Core Network nodes.

BOARD DETAILS Device Board Module (DBM) CPP provides a hardware device design platform. It comprises a schematic and component list with application information on how to implement the Device Board Package (DBP) function on the device boards. It also includes Core software. The device designer has only to design the software and the hardware for his application. A Board Processor Module (BPM) is a specification of a hardware design, which together with the Switch Port Interface Module (SPIM), is incorporated on all boards that are included in the ATM subrack. The BPM module also handles basic Light Emitting Diode (LED) functionality and Product Identity (PID) information. The interface between the SPIM and the user application is called Switch Access Interface (SAI) and is built on an open industrial standard, Utopia, an ATM interface for which there are a number of commercial ATM adaptation parts available. The BPM and the SPIM together is called the Device Board Module (DBM). The DBM is a standard module that is used by hardware designers to design application boards and is the base for almost all CPP boards. One of the few boards which is not based on the DBM is the General Purpose Board (GPB). Switch Core Board 2 (SCB2) This board contains: • ATM switch core • Circuits for distribution of system clock (19.44 MHz) • Interfaces for connection of four Inter Subrack Links (ISL), with a maximum user data bandwidth of 330 Mbps per link. The aggregated bandwidth of the four Inter Subrack Links is limited to 620 Mbps by back-pressure with fair share. • Interfaces for connection of fan supervision signals • -48V DC power connectors, filtering, supervision and distribution Switch Extension Board (SXB)

The board includes four Inter Subrack Links (ISL) with the same characteristics as the ISL links on the SCB. This board is used when building large nodes when the internal links on the SCB not are not sufficient for interconnect the extension subracks. General Processor Board (GPB) The General Processor Board (GPB) is a general processor with 8 MB flash memory and 1024 MB DRAM and a 1.5 GB Flash Disk. It also includes Ethernet and serial communication interfaces for management access. The board uses one slot (15mm). GPB is used as an MP today in the commercial system. Timing Unit Board (TUB) This board has the System clock oscillator (19.44 MHz), which is very stable (50ppb accuracy and 1h holding time). The clock regenerates and stabilizes a reference-timing signal synchronized to one of the ETs connected to the public network and has a very good long-term stability. The board also has support for an application for handling the node synchronization procedures for WCDMA. Exchange Terminal Board (ETB) The Exchange Terminal boards provide interfaces for traffic over various types of transmission lines. The Exchange Terminal boards are designed with a modular hardware structure. Different versions of Exchange Terminals are needed in order to implement adaptations to different physical media, as described below. ET-C41 ET-MC41 has four 155 Mbps optical port for switching of TDM traffic. MSP 1+1 link protection is supported, but two boards are required for that function. ET-M4 ET-M4 has two 155 Mbps (STM-1/STS-3c according to ITU-T G.957) optical ports for ATM. The board supports AAL2 multiplexing. For SDH and SONET, the ET-M4 maps the 155 Mbps channels into VC-4s according to ITU-T I.432.2. This board is used in the ATM Extension Subrack. ET-M4 uses one slot in a subrack. ET-M4/22 The board has two optical STM-1/OC-3 (2 x 155 Mbit/sec) unchannelized interfaces for ATM cell transport. The board also supports multiplexing and demultiplexing of AAL2U and AAL2.

ET-MC41 ET-MC41 has one 155 Mbps optical port for ATM and TDM. The board supports AAL2 multiplexing, Inverse Multiplexing for ATM (IMA) and Circuit Emulation with AAL1. ET-MC41 uses two slots in a subrack. ET- MC1 ET-MC1 has 8-ports board and is configurable for 2Mbps (E1) interface, either ATM or TDM or 1.5 Mbps (T1). The ATM mode can use a fraction of the 2 Mbps capacity and supports AAL2 multiplexing on the board. This is in compliance with the ITU-T standards I.432.1 and I.432.3. ATM cells are mapped on to PDH bit stream according to ITU-T G.804. The TDM mode uses a 2048 kbps synchronous interface according to the ITU-T standards G.703 and G.704 carrying TDM traffic. When used in TDM switching mode, single 64 kbps time slots within 2 Mbps interface can be switched. Circuit emulation with AAL1 is supported with up to 4 circuit emulated connections from the same physical interface. ET-MFG The ET-MFG is an exchange terminal board that enables direct IP connections to a M-MGw node. The board has two 1 Gigabit Ethernet interface (1000Base-T) ports

OPERATION AND MAINTENANCE For this instruction please refer to M-MGW R4.1 Ericsson ALEX and MGW Element manager on site.

5.1

ELEMENT MANAGER M-MGw Element Manager The M-MGw Element Manager offers an easy-to-use GUI to the node, hiding the inner complexity of the node database. The Element Manager application client (built as Java applets) is included in the M-MGw node. The web browser running on the client fetches the applets from the node and runs them on the client. The management interfaces are implemented by using the CORBA (Common Object Request Broker Architecture) technology by means of the IIOP (Internet Inter-ORB Protocol) interface.

All Element Management functions are embedded in the node which means that the M-MGw itself contains all the software required to perform all management tasks related to that node. The equipment required for management is a standard PC with a web browser, a Java virtual machine and an Ethernet card installed. The connection can be local over an Ethernet cable or remote via IP-based interface over ATM or Ethernet. The user will need to know the IP address (URL) of the M-MGw. Configuration Management The M-MGw supports configuring and controlling items such as physical interfaces, link protocols and devices. All software required for configuration is contained on the M-MGw. A GUI or a scripting interface enables the setting and modification of parameters associated with the M-MGw configuration, in case of initial configuration or in case of changes in the network like new nodes/links being installed. These changes may need to be reflected in the MMGw. The following actions are supported via the Element Manager: • Transport service configurations • Signaling configurations • Media Stream Board configurations • Virtual Media Gateway configurations • Configurations of Terminations for Virtual Media Gateways • Configurations for Interactive Messaging • Physical interface configurations Performance Management Support for Performance Management in the M-MGw includes the facility to maintain statistics about the usage of all aspects of the M-MGw functions. The Sub-Network Management System (such as Ericsson OSS-RC) is needed to activate them. A similarly collected PM Statistics file needs to be read using FTP/SFTP. The following items can be measured: • Virtual Media Gateway Application statistics • Media Stream Platform statistics • Signaling statistics

• Transport Service statistics • Physical Interface statistics The Performance Data IRP provided by the node makes it possible or performance management systems in the sub-network management (e.g. OSS-RC) to control the measurements. ELEMENT MANAGER General All accessibility to Element Management functions is performed via graphical user interfaces (GUI). The operator uses a thin client (PC with Windows or Workstation with Solaris) with a web browser including a Java Virtual Machine (JVM) installed. The web browser is used to download and start the embedded Element Manager, from which all element management functions can be accessed using graphical user interfaces. All element management functions are accessed from the main window that is started up first when the node is accessed. Thin client The thin client is a standard web browser (on a PC with Windows or on a Workstation with Solaris) that the operator uses to communicate with the O&M system. It consists of both industrial standard hardware and commercial standard software, neither is Ericsson specific. The hardware and software requirements of the thin client are as follows: •

Web browser with support for Java applets (I.e. Netscape or Microsoft Internet Explorer)

•

PC system requirements: Windows-NT or Windows 98, 2000 or XP

•

Workstation system requirements: Solaris7 with Netscape 4.06

•

Ethernet connection for 10 BaseT

•

FTP Client (e.g. for retrieving Product Inventory log file)

The thin client is connected to the O&M Intranet via Ethernet, either locally at site or remote from a network management centre. Local connection is performed via the Ethernet port at the top of the CPP cabinet. Remotely this is done by connecting the thin client to a LAN, which is connected to the O&M Intranet via a gateway router.

All specific software needed to manage the CPP based nodes is uploaded to the thin client and therefore does not need to be preinstalled. Once the node’s software is updated, the management software is also upgraded. The software at the thin client will be updated automatically once the operator is connected. Main Windows Each main window consists of a menu bar at the top from where all functions can be reached, a left pane where different topologies can be viewed and a right pane where information about the selected object and all subordinate objects is shown. The element management functions can also be reached by selecting an object in the left pane and make a right click on the mouse. The topology in the left pane can be changed to show different topology views. The main window is the central access point for all Element Management functions. It is possible to reach all functions either from a functional oriented view (the menu bar) or from an object oriented view (from the left pane). Left Pane The left pane in the main window shows the topology of the node. CPP supports: • Equipment View • Software View • ATM View • IP View • SS7 View Node specific views, such as Virtual MGw View can be added as a node specific element management application. Only one topology view can be shown at a time in one main window. The operator can select a number of objects in the topology view and then select a function by right clicking on the mouse. Right Pane The leaf1 objects are shown in the Right pane. The Right pane is updated when an object in Left pane is selected by a single, double or right clicks. The columns in the Right pane show the most important properties of the object selected, in the Equipment View, if applicable. These are: • Name

SYSTEM UPGRADES General The software management feature allows the operator to install an Upgrade Package (UP) on a node and upgrade the node. All new or changed software is transferred to the network element as an Upgrade Package (UP). The UP may contain for instance: • New major functionality • Some minor new functionality and improvements • Fault corrections The system upgrade is done in three phases.

1. The first phase is to create the Upgrade Packet. This is created in the Element Manager. An Upgrade Packet is a description of the new system. It contains load modules, documentation, upgrade control file (ucf.xml), Application Upgrade Engine (AUE) and Jar files. When creating the upgrade packet the load modules have to be linked with the boards in the node in the Upgrade Control File. This file is created in the Software Manager of the Element Manager. The tools for this are: • Software repertoires A software repertoire is a group of load modules that will execute on the same processor. For example, all load modules that will execute on the core MPs will be grouped together in the same repertoire (ex. CORE_MPs). • Software allocations The repertoires define the load modules that will execute in all the processors. However, they will not define where the processor is. The software allocation links the correct set of repertoires to the correct set of boards. Example, the core MPs in a M-MGw is located on slot 2 and 3 in the Main Subrack. The software allocation links the repertoire, CORE MPs, to these slots. 2. The second phase is the installation phase when the UP is transferred from a central placed FTP server to the node. The UP will be installed on the internal flash disk in the node. 3. The third phase is the upgrade phase when the software in the UP will be loaded from the flash disk and activated. The UP includes information about if the upgrade should be soft or hard. “Hard” means a node restart will be performed. “Soft” means no restart and thereby less traffic impact.

5.3

FAULT MANAGEMENT GENERAL When a fault occurs in the Network Element, it is possible to issue two different types of alarms, a primary alarm and secondary alarms. The primary alarm contains information about the original fault (the root cause) and the secondary alarms about the consequences the fault generates.

All current alarms in the Network Element, i.e. the active alarm list, and the alarm log can be viewed from the element management application implemented in the network elements. Whenever a fault is detected in the network element an alarm is raised and the active alarm list is updated. The alarm disappears from the active alarm list when it is cleared. It is then moved to the alarm log. There exists an alarm log within a network element where all alarms are stored. The alarm log is persistent and the size of the alarm log can be altered.. The alarm log provides all alarm information, like alarm state changes. When an alarm is ceased, the state change will be logged, but the alarm will not be removed from the alarm log. It is possible to view the content of the alarm log. In each alarm there is unambiguous information that points to the fault objects. There is an Operation Procedure documentation on-line connected to each alarm with suggested repair actions. Alarm Suppression An overall goal with Fault Management functionality is to reduce the amount of alarms that are issued from the network. To support that, CPP provides support for alarm suppression. The majority of fault situations will produce only one primary alarm and when applicable also a secondary alarms. Alarm Subscription In the Network Elements only simple subscription of alarms is supported. It allows for either subscription to all alarms or switch off the alarm subscription completely.

The fault management service includes active alarm list administration, alarm log. The notification service handles subscriptions for alarms and sends notifications to all clients that have subscribed to the alarms. The actual alarm is created in the management adaptation layer where a fault indication is tagged with the following information: •

Event type.

The event type identifies an alarm type in the alarm record, e.g. Communication, Environmental, Equipment, Processing Error and Quality of Service. •

Probable cause.

Each alarm will have a probable case value. It qualifies an alarm and provides further information than the event type defined above. •

Severity level.

There will be a perceived severity value for each alarm in the node. It indicates the relative urgency for operator attention, e.g. critical, major, minor and warning. •

Specific Problem

Additional text (optional)

•

Additional information (optional)

The alarm handling within a network element relies on the ITU x.733 alarm reporting function and supports the Alarm IRP specified by 3GPP (TS 32.1112). These documents provide information about the content of the alarm reports and alarm transfer protocols that can be used. The alarm handling feature includes the following functions: •

Active Alarm List administration.

The Active Alarm List contains a list of alarms, which are active in the system. The active alarm list is presented to the operator via a graphical user interface •

Alarm Log administration

The Alarm Log contains the history of alarms, which have been generated in the system. The alarm log is viewable for the operator.

Alarm Subscription.

The Alarm Subscription sub-function is responsible for the set-up and maintenance of alarm subscriptions in the system. An alarm is notified to a subscriber after the subscriber has made a subscription for that alarm. •

Alarm Manipulation

The operator can acknowledge/un-acknowledge alarms and write a comment to a particular alarm. •

Alarm Distribution

Distribution of alarms to a sub-network manager or overall network management system. CPP supports CORBA as solution-set for the Alarm IRP (TS 32.111-3).

LOGS There are different logs defined in the CPP system in which different information can be retrieved. The following logs exits •

Historical Alarm Log:

One alarm log per Network Element. All alarm status changes are logged in the alarm log. •

Event Log.

One log per network element. All events, which are not alarms i.e. they don’t have any state, are stored in this log. An example of an event is the restart event. All the logs are using the “Round-Robin” principle, i.e. when they are full the oldest information will be overwritten. It is possible to handle the logs as files and export them to any external media if they need to be stored for a long time for some reason. It is however not recommended, because they cannot be viewed outside the node without special tools. The logs on the network element can be viewed from the element manager.
