It is a generic term for logical functional entities that control IP multimedia services at the core layer. In R7, the standardization of fixed-mobile convergence FMC is enhanced. The softswitch technology emerged in The technology is mature now after multiple development phases such as the experiment and commercial use phases. In the world, several telecom operators have already launched the softswitch experiments.

Configuring Inner Standalone H. After the inner standalone is configured, the internal phones can call each other using the internal extension numbers even if the interface between the gateway and the softswitch is interrupted.

Context The MG interface supports the inner standalone function only when it uses the H. When the MG interface works in the inner standalone state, only the internal users of the MG interface can communicate in the normal state.

To maintain the same user phone number in the standalone state as the one used in normal condition, configure the phone number on the MG to be the same as that on the MGC. Prerequisite The voice service users are configured properly on the H. The user phone number of the H. Command: mgpstnuser modify H. Procedure Configure inner standalone based on H. Run the digitmap set inner command to configure the internal digitmap.

NOTE: The configured digitmap should correspond to the user phone number. Optional Run the standalone parameters command to configure the inner standalone timers. The inner standalone timers include the dial tone timer default: 10s , the busy tone timer default: 40s , and the ringing tone timer default: 50s. Generally, the default inner standalone timers can be used. Configure inner standalone based on SIP protocol Run the mg-software parameter 2 1 command to configure the SIP interface to support the inner standalone function.

By default, the SIP inner standalone function is disabled. Optional Run the local-digitmap add command to add a digitmap used in SIP inner standalone.

The system has a digitmap named defaultnormal, which can match any phone numbers. Therefore, a new digitmap does not need to be added unless otherwise required. Example Assume that an incoming third-party call will interrupt the inner standalone call after the communication between MG 0 and the MGC recovers. S Exx.



Network Transformation -- Challenges and Opportunities for Network Carriers Traditional carriers are now facing three main challenges: A. Saturation in fixed-line and wireless voice markets. Lack of an effective strategy and sufficient profit margins for broadband services. The need for transformation The prevalent trend in the telecom market exhibits wireless technologies replacing fixed-line telephony, voice services giving way to non-voice services, and ICT convergence superseding traditional business services. The fixed network market has undergone substantive, structural changes in terms of increasingly demanding market requirements, the impact of technological progress and fresh challenges due to increased competition. Telecommunications is now focused on the integration of multimedia information and the convergence of IT and CT in corporate applications.
