Patent ID: 8422506

Claim:
A mobile communication device for load balancing management, comprising: a wireless module receiving data communication services from a service network via a first service node, and receiving a plurality of system information messages from the first service node and a plurality of second service nodes, wherein each of the system information messages comprises a forward-link quality threshold corresponding to a respective service node; and a controller determining a traffic type of the data communication services and a signal indicator of the first service node, determining whether the signal indicator is less than the forward-link quality threshold corresponding to the first service node, and switching the data communication services from the first service node to one of the second service nodes according to the traffic type in response to that the signal indicator is less than the forward-link quality threshold corresponding to the first service node, wherein after switching the data communication services from the first service node to one of the second service nodes, the controller further waits for a predetermined time interval before performing a determination procedure to determine whether a random number is less than a predetermined threshold corresponding to the forward-link load level of the switched second service node, and switches the data communication services to another second service node or the first service node in response to that the random number is less than the predetermined threshold.
