Heterogeneous wireless network in the future will provide users with more service selections. The user can select
the network with the best effect based on the specific demand and individual preference, and random selection will
not only cause disorder of the network and low load efficiency but also impact the user’s experience. The previous studies
believe that the attribute of the network only has monotonous impact on the utility of user’s use, namely, the larger the efficiency
indicator the better, and the smaller the cost indicator the better. However, in reality, it changes with the conditions.
The study divides the users into two types of quality preference and cost preference based on the model of multiattribute
decision-making and constructs the network selection model in the environment of heterogeneous wireless network
targeted at the voice business, video business and data business by taking into account the decision attributes of
network bandwidth, delay, response speed, safety, cost to use, etc., thus realizing the objective of increasing the network
utility of the user under the circumstance of adding no load to the network.
