摘要：
A method and apparatus determine a caller's eligibility to enter a lottery, determine whether the caller has won the lottery and advise the caller of the winning status in response to a caller's request for communication services. The odds of winning a lottery for the caller can be adjusted based on the caller's participation history, such as a past number of calls made or total call time logged by the caller. Thus, frequent users of a communication service can be rewarded with increased odds of winning a lottery each time a request for communication services is made and communication services are provided.
