Claim:
A computerized method for evaluating levels of importance of missed incoming calls of a communication device, the method comprising: defining one or more reference parameters in relation to incoming calls received by the communication device, and defining a function for evaluating the levels of importance of the missed incoming calls using the one or more reference parameters; determining whether an incoming call is missed when the incoming call is received by the communication device; obtaining the one or more reference parameters in relation to the received incoming call when the received incoming call is missed; and evaluating a level of importance of the missed incoming call by applying the obtained one or more reference parameters to the defined function; wherein the one or more reference parameters comprise a first parameter X 1 , a second parameter X 2 , a third parameter X 3 , and a fourth parameter X 4 , the first parameter X 1 represents a period of ring time of the incoming call when the incoming call is held on the line until the incoming call is processed, the second parameter X 2 represents a contact group in which an incoming call number of the incoming call is stored, the third parameter X 3 represents a number of times that the incoming call number of the incoming call has communicated with the communication device during a predetermined time period, and the fourth parameter X 4 represents a total talk time that the communication device engages with the incoming call number of the incoming call during answered calls within the predetermined time period; wherein the defined function is a linear function: Y=a 0 +a 1 X 1 +a 2 X 2 +a 3 X 3 +a 4 X 4 , where a 0 , a 1 , a 2 , a 3 , and a 4 are predetermined coefficients; wherein the coefficients a 0 , a 1 , a 2 , a 3 and a 4 are predetermined by: determining n groups of sample values {Y i , X 1i , X 2i , X 3i , X 4i , 0≦i≦n} by a user; applying the n groups of sample values to the defined function to obtain an equation Y i =(a 0 +a 1 X 1 +a 2 X 2 +a 3 X 3 +a 4 X 4 ), 0≦i≦n; and calculating the coefficients a 0 , a 1 , a 2 , a 3 and a 4 using a generalized least squares method based on the obtained equation; wherein the level of importance of the missed incoming call is evaluated by: calculating a solution Y of the linear function by applying the obtained one or more reference parameters to the linear function; and determining the level of importance of the missed incoming call according to the solution Y of the linear function.
