Abstract: Disclosed are an access method and device in a heterogeneous network for solving the problem that, in network selection of a heterogeneous wireless network, a user can only enjoy at any one time the service of one network and cannot simultaneously enjoy the services of different networks, the method comprising: dividing access points capable of providing a service for a user equipment (UE) into at least one competition group; and determining the access overhead of the competition group, and selecting for the UE, according to the determined access overhead of the competition group, a target competition group from the competition groups for accessing. A network multi-path routing and traffic distribution model is established, such that the UE can select different access methods, thus providing a new traffic operation mode for network development.
