Frequency Management:
The function of frequency management is to divide the total number of available channels into subsets which can be assigned to each cell either in a fixed fashion or dynamically (i.e., in response to any channel among the available channels). The terms "frequency management" and "channel assignment" often create some confusion. Frequency management refers to the designation of channels and voice channels (done by the FCC), numbering the channels (and done by the FCC), and grouping the voice channels into subsets. Channel assignment refers to the allocation of specific channels to cell sites and mobile units. A fixed channel set consisting of one or more subsets is assigned to a cell site on a long-term basis. During a call, the particular channel is assigned to a mobile unit on a short-term basis. For a short-term assignment, one channel assignment per call is handled by the mobile telephone switching office (MTSO). Ideally channel assignment should be based on the least interference in the system. However, most cellular systems can not perform this way.
