发明名称 Method and system for adapting a channel assignment plan to include shared frequency channels
摘要 In a cellular communication network (20) having a channel assignment plan (28) that distinguishes frequency channels (34) assigned to a plurality of cells (24), a method (58) and system (46) adapt the channel assignment plan (28) during network planning to include shared frequency channels (45). Borrower cells (84) are identified in response to a deficiency value (36) indicating a shortage in a quantity of the frequency channels (34) assigned to the borrower cells (84). Donor cells (95) are selected from the cells (24) in response to a load factor (38) for each of the cells (24), the load factor (38) indicating the number of frequency channels (34) already being shared by the cell (24). Candidate frequency channels (34) that may be shared are evaluated against predetermined channel sharing constraints, such as frequency separation constraints (156, 158), co-channel carrier-to-interference C/I constraints (232, and adjacent channel C/I) constraints (280).
