Disclosed are a method and an apparatus for handover between heterogeneous networks. The method comprises: obtaining, for each of a plurality of candidate networks, parameters of the candidate network including a packet loss rate and a network load, and taking the obtained parameters as decision parameters of the candidate network; obtaining each of preset service types and a preset weight factor for at least one user preference corresponding to the preset service type; calculating weights of decision parameters for each preset service type by using the decision parameters of the candidate network and through an Analytic Hierarchy Process, and determining a weight vector for the preset service type; adjusting the weight vector for each preset service type by using the preset weight factor; calculating, using the weight vector and through an intuitionistic trapezoidal fuzzy multi-attribute decision-making algorithm, a score for each of the candidate networks, determining the candidate network with the highest score as a target network, and triggering a handover.
