Entity of CS core networkEntity of CS core network

For the ATM and IP transport, there is a strict separation

between the call control level and the bearer control level.

The MSC server shall provide the call control and mobility

management functions

The media gateway shall provide the bearer control and

transmission resource functions. The media gateway shall

contain the stream manipulating functions.

ContextContext

A Context is an association between a collection of

Terminations.

The Context describes the topology (who hears/sees

whom) and the media mixing and/or switching parameters

if more than two Terminations are involved in the

association.

Context ID represents one context



Termination Termination

Termination is a logic entity of MGW, which can receive

and send media or control stream.

Termination can be described into one time slot , IP

address + port number or VPI/VCI



Command： Add/Modify/SubtractCommand： Add/Modify/Subtract

ADD : add one termination into a context

MODIFY : modify the property, event or signaling parameter of the te

rmination ,such as modify codec type, detect offhook /clear signal

SUBTRACT : remove a termination from its context



Command：Move/AuditValue/AuditCapabilitiesCommand：Move/AuditValue/AuditCapabilities

MOVE : move a termination into another context

AUDITVALUE : returns the current values of properties,

events, signals and statistics associated with Terminations.

AUDITCAPABILITIES: return the possible values of

capability of terminations



Command： Notify/ServiceChangeCommand： Notify/ServiceChange

NOTIFY : MGW report the events occurring within the Media

Gateway

SERVICECHANGE

MGW report one or more termination into/out of service.

MGW report the events of restart or logout

Procedures for configuring basic dataProcedures for configuring basic data

Procedure Command

Step 1: Negotiate and prepare data -

Step 2: Configure MGW information ADD MGW

Step 3: Configure SCTP association information for interworking with MGW

ADD MCLNK

Step 4: Set SCTP Checksum Algorithm (optional) SET SCTPPARA

Step 5: Set tone play language (optional) SET TONECFG

Step6: Configure MGW tone ID (optional) ADD TONEID



Interworking with MGW ConfigurationInterworking with MGW Configuration

Configuring MGW Information

Command:ADD MGW

This command is used to add a new media gateway, and to se

t its basic information and MGW capability.

Configuring Mc Interface Link

Command:ADD MCLNK

This command is used to add a link used by Mc interface confi

gured to certain MGW based on corresponding transport proto

col: UDP, MTP3B and SCTP.




Modifying SCTP Checksum Algorithm (Optional)

There are two SCTP checksum algorithms supported in

MSOFTX3000: ADLER32 and CRC32.

Command: SET SCTPPARA

Setting Tone Playing Capability of MGW (Optional)

The command defines the language and cycle times of all tone

clip files played in MGW.

During system initialization, the default setting is loaded that

language is English and cycle number is 2.

Command: SET TONECFG




Modifying Individual Tone IDs (Optional)

The command is used to modify the cycle times of individual

tone clip files.

Command: MOD TONEID
