Abstract
In a cellular communication network ( ) having a channel assignment plan ( ) that distinguishes frequency channels ( ) assigned to a plurality of cells ( ), a method ( ) and system ( ) adapt the channel assignment plan ( ) during network planning to include shared frequency channels ( ). Borrower cells ( ) are identified in response to a deficiency value ( ) indicating a shortage in a quantity of the frequency channels ( ) assigned to the borrower cells ( ). Donor cells ( ) are selected from the cells ( ) in response to a load factor ( ) for each of the cells ( ), the load factor ( ) indicating the number of frequency channels ( ) already being shared by the cell ( ). Candidate frequency channels ( ) that may be shared are evaluated against predetermined channel sharing constraints, such as frequency separation constraints ( ), co-channel carrier-to-interference C/I constraints ( , and adjacent channel C/I) constraints ( ).
