Describe the significance of the Mobile Termination (MT) in GSM communication.

Last updated on 


In GSM (Global System for Mobile Communications) communication, the term "Mobile Termination" (MT) refers to the termination point for incoming communication on the mobile network. It specifically relates to the receiving end of a mobile communication link, where the call or message is directed towards a mobile device. Here's a technical explanation of the significance of Mobile Termination in GSM communication:

  1. Terminology Clarification:
    • "Mobile Termination" is often used in the context of call setup and messaging to denote the receiving end of a communication. It contrasts with "Mobile Originating" (MO), which refers to the initiating end, such as when a call or message originates from a mobile device.
  2. Call Termination:
    • In the context of voice calls, Mobile Termination is the process of connecting an incoming call to the intended recipient's mobile device. This involves routing the call from the calling party through the mobile network to the destination Mobile Termination point.
  3. Significance in Call Routing:
    • Mobile Termination plays a crucial role in call routing within the GSM network. When a call is directed towards a mobile subscriber, the network identifies the Mobile Termination point associated with the called subscriber's location and connects the call accordingly.
  4. Messaging Termination:
    • For Short Message Service (SMS) and other messaging services, Mobile Termination refers to the delivery of messages to the recipient's mobile device. The GSM network ensures that the message is terminated at the correct destination.
  5. Location Tracking:
    • The significance of Mobile Termination is also related to the tracking of the location of the called mobile device. The network uses location information to route the call to the correct serving Mobile Switching Center (MSC) and Base Station (BS) associated with the called subscriber.
  6. Network Handover:
    • In the case of handovers, where a mobile device moves from one cell to another during an ongoing call, the Mobile Termination process involves smoothly transitioning the call to the new serving cell without interrupting the communication.
  7. Billing and Charging:
    • Mobile Termination is essential for billing and charging purposes. The termination point is used to determine the termination rate, which is the fee charged to the calling party for terminating the call on the called party's mobile network.
  8. Service Quality:
    • The Mobile Termination point is critical for ensuring the quality of service during a call or message delivery. It involves managing handovers, minimizing delays, and maintaining the integrity of the communication link.
  9. Integration with Other Services:
    • Mobile Termination is integrated with various services provided by the mobile network, including voice services, messaging services, and data services. It ensures that incoming communications are correctly delivered to the intended mobile device.

In summary, the significance of Mobile Termination in GSM communication lies in its role as the endpoint for incoming calls and messages. It involves call routing, location tracking, billing, service quality management, and integration with other network services to ensure a seamless and reliable communication experience for mobile subscribers
