Disclosed is a method for mobility management of group terminals, where a mobility management platform sends a request for calling a service to a terminal of a group, and determines a terminal responding to the request for calling the service as a service center of the service; and the service center of the service configures a terminal environment according to the request for calling the service to which the service center of the service responds, and uploads information on the configured terminal environment to the mobility management platform. Also disclosed are a system and equipments for mobility management of group terminals. With a solution of the disclosure, in the case of multiple services, it is possible to select, from different terminals, a terminal as a service center according to the service, thereby avoiding a ping-pong effect, increasing utilization efficiency of network resources, enhancing optimal user experience of QoS, and meeting a management requirement in parallel transmission of multiple service flows in a ubiquitous network.
