the historical communication record information of the user of the local network can comprise: the historical communication record information of the first user whose network access time does not exceed the preset time period and/or the historical communication record information of the second user whose network access time exceeds the preset time period, for example, the preset time period may be three months. The historical communication record information can be obtained from a historical call ticket and/or a short message ticket, and can comprise one or more items of a calling party, a called party, call time, call duration and short message time.
S102: obtaining an intimacy index model of the home network user and the different network users according to the historical communication record information of the home network user;
after the historical communication record information of the user of the local network is obtained, data for representing the historical communication characteristics of the user, such as the number of calls, the call duration, the number of people in the call, the number of times of messages, the number of people in the messages and the like, can be extracted from the historical communication record information, training is carried out based on the extracted data, and an affinity index model can be obtained.
The intimacy index model can be obtained by:
extracting historical communication record information of a user who changes from a different network to a home network before accessing the network and historical communication record information of the user after accessing the network to obtain two historical communication characteristics representing the user before accessing the network and after accessing the network; establishing an equation set containing unknown coefficient vectors according to the relationship between the two historical communication record characteristics and the intimacy index; solving the equation set according to the relation that corresponding affinity indexes of the user before and after the user accesses the network are the same, and obtaining a coefficient vector; and expressing the relation between the historical communication characteristics of the user and the intimacy index by using the obtained coefficient vector to obtain an intimacy index model.
