METHODS AND APPARATUS PERTAINING TO HANDOFF IN A MOBILE TELECOMMUNICATION SYSTEM |
摘要 |
The invention relates to a method and apparatus in a system comprising cordless telecommunication. The inventive method and apparatus utilize fuzzy-logic to evaluate at least two radio communication parameters when making a handoff decision, or to produce basic data on which a handoff decision can be made. The parameters are assigned membership to at least two input data sets, each having its own membership function. The parameters are divided into groups and a rule table of fuzzy-condition statements is formed. The fuzzy-condition statements are executed and the consequences weighted to a crisp-value which is used in conjunction with handoff. The inventive apparatus includes a fuzzy-processing unit for grouping parameters and executing rules, a unit for determining the crisp-values, for instance the average value, maximum value and/or the minimum value of rule consequences, and an evaluating unit which uses the crisp-values in conjunction with establishing a candidate list or in making a handoff decision.
