The invention relates to a mobile load balancing method and system. The method comprises the following steps: A, calculating resources are distinguished, and different calculating resources are separately restored in different servers; B, a dynamic route list of server addresses corresponding to the calculating resources is generated; C, when a service request of a mobile terminal is received, the server address of the required calculating resources needed by the request is determined according to the dynamic route list; and D, the address determined by the step C is sent to the mobile terminal. According to the invention, original DNS service and load balancing service can be replaced by coordination calculating between the mobile terminal and the server terminal, so that demands of present large scale cloud calculating and quick linking of the service terminal are satisfied.
