RTNets CS Architecture

RTNets CS Architecture 1. SoftX3000, the Softswitch equipment, which fulfill call control, access control of media gateway, distribute resources, process the protocol, routing and accounting, etc. SoftX3000 provide API for the third part applications, and use SIP or SIP-I protocol with other softswitch. The IP address of SoftX3000 is 172.24.253.30. The phone numbers of those in SoftX3000 are 9200XXXX. 2. iOSS , integrated Operation Support System, which includes integrated network management system for NGN equipment managing and accounting system.3SCP, Service Control Point, which is the core of the intelligent network, and store user data and service logic, control SSP for service action.4MRS6100, Media Resource Server, process media for services, such as, provide service tone, IVR, some advanced audio service, etc. 5U-NICA, the Application Server, which responsible for the logic creation and management of those value-added service and intelligent network service, the Application Server can provide API for a third part development. 6SG7000, Signaling Gateway, which fulfills transformation between No.7 signaling in PSTN and signaling in IP network (such as SIGTRAN).

RTNets CS Architecture 7USAU, Universal Signaling Access Unit, which makes signaling transformation, especially transformation between INAP and corresponding signaling in IP network. 8UMS N2000, the integrated network management system. 9Eudemon2100, the session border controller, help signaling and media message traverse NAT and firewall. 10UMG8900, Universal Media Gateway, which is mainly a trunking gateway, with SG and AG function inside. The encoding and decoding arithmetics UMG8900 supported are G.711, G.723.1, G.726, G.729.11UA5000, an integrated access device, which provides interfaces to different kinds of users, such as analog users, ISDN users, xDSL users, etc.12IAD, Integrated Access Device, access data, audio and video services to IP network for user, and support G.711 arithmetic.13openEye, which is a SoftPhone using SIP protocol, and support G.711, H.261 and H.263 arithmetic.

Test description

TEST NUMBER:

TITLEBasic Call between SIP users

SUBTITLE normal call

PRE-TEST CONDITIONS

1SIP user 1 registered on SS1; SIP user 2 registered on SS2.

TEST CONFIGURATIONSIP1SS1SS2SIP2

TEST STEP

1User1 calls user2user2s phone rings

2User2 answers the call

3User1 hangs up first,then user2 hangs up,too.

EXPECTED SIGNAL SEQUENCE:

(1)SIP user1 sends an INVITE request to SS1 to setup a sessionSS1 responses 100 Trying.SS1 forwards the INVITE request to SS2 then to user2.

(6) SIP user1 rings .User 2 sends a 180Ringing response to SS2,SS2 forwards this message to SS1 then to user1.

(9)User2 answers the call ,User 2 sends a 200 OK response to SS2 then to User1.

(10)User1 sends ACK back.

User1 and user2 setups a multimedia session.
