Who has the responsibility of billing and system maintenance function in cellular system? Explanation: Mobile switching center (MSC) accommodates 100,000 subscribers and 5,000 simultaneous conversations at a time and handles all billing and system maintenance functions.

What is the responsibility of msc in cellular telephone system

All cellular systems have at least one MTSO which will contain at least one MSC. The MSC is responsible for switching calls to mobile units as well as to the local telephone system, recording billing data and processing data from the cell site controllers. The MSC is connected to a close telephone exchange by a trunk group. This provides an interface to the (Public Switched Telephone Network) (PSTN). It also provides connectivity to the PSTN.

Summary

The MSC is responsible for switching calls to mobile units as well as to the local telephone system, recording billing data and processing data from the cell site controllers. This provides an interface to the (Public Switched Telephone Network) (PSTN). It also provides connectivity to the PSTN.

Which two channels are responsible for initiating mobile calls?

The two channels responsible for initiating mobile calls are the forward control channels (FCC) and reverse control channels (RCC). Control channels are often called setup channels because they are only involved in setting up a call and moving it to an unused voice channel.

What is a call in cellular system?

A new user located in a given cell requests a channel by sending a call request to the cell’s base station over a separate control channel. The request is relayed to the MTSO, which accepts the call request if a channel is available in that cell. If no channel is available, the call request is rejected.

Which one of the following is not referred as the characteristics of the cellular telephone system?

Explanation: The large frequency spectrum is not referred to as one of the characteristics of a cellular telephone system as the cellular communication accommodates a large number of users using a limited frequency spectrum over a large geographic area.

What is condition for intersystem interference?

An MSC engages in an intersystem interference when a mobile becomes weak in a given cell and MSC cannot find another cell to which call can be transferred.

Which of the following are the main parts of basic cellular system?

A cellular communication system consists of four major components—namely, a public switched telephone network (PSTN), a mobile telephone switching office (MTSO), cell sites with antenna systems, and mobile subscriber units (MSU).
