Detailed explanation-1: -In dynamic channel assignment strategy, voice channels are not allocated permanently. Entire pool of frequency channels lies with MSC and each time a call request is made, the serving base station requests a channel from the MSC. Switch then allocates a channel to the requested cell following a algorithm.

Detailed explanation-2: -Dynamic Channel Assignment (DCA): Dynamic Channel Assignment is a strategy in which channels are not permanently allocated to the cells. When a User makes a call request then Base Station send that request to the MSC (Mobile Station Cente) for the allocation of channels or voice channels.

Detailed explanation-3: -Dynamic Channel Assignment (DCA) assigns the channels to the cells dynamically according to traffic demand, and hence, can provide higher capacity (or lower call blocking probability), fidelity and quality of service than the fixed assignment schemes.

Detailed explanation-4: -FCA is less expensive than DCA. DCA is costly as it requires real-time computation. Once a call is finished in FCA, the cell retains the assigned channels. When a call is concluded in DCA, the channel or voice channel is returned to the MSC.

Detailed explanation-5: -Explanation: Handoff is the process of changing the channel associated with current connection while a call is in progress. Explanation: The interference between the neighbouring base stations is avoided by assigning different group of channels and reusing the same channel after a certain amount of distance.
