Abstract:
Mobile communication devices and integrated circuits thereof are provided. The mobile communication device, communicating with a packet switched network and a second network, includes a transceiver, a first PLL circuit and a controller. When exchanging an ongoing data transmission with the packet switched network, the transceiver transmits a first message to the packet switched network, which indicates the mobile communication device will be tuned away from the packet switched network, and performs a subsequent procedure for the second network. The first PLL circuit provides a first clock to the transceiver. When the ongoing data transmission with the packet switched network is not completed, the controller controls the first PLL circuit to switch the first clock from a first clock frequency to a second clock frequency after the transceiver transmits the first indication message.

An interworking system in the second mobile service network interconnects the first mobile service network with the second mobile service network, by connecting to a mobility management entity in the first mobile service network, to enable the first mobile service network to provide the circuit-switched domain service to the user equipment via the second mobile service network.
Abstract:
A mobile communication device for prioritized load balancing is provided. In the mobile communication device, a wireless module receives data communication services and a broadcast message from a first service network. Also, a controller determines whether the broadcast message has load balancing information for the first service network and a second service network, and in response to the broadcast message having the load balancing information, generates a random number and determines whether the random number belongs to a restricted priority level according to the load balancing information. The controller further suspends a reselection from the first service network to the second service network, in response to the random number belonging to the restricted priority level.
Abstract:
A mobile communication device for load balancing management is provided. In the mobile communication device, a wireless module receives data communication services via a first service node and receives 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 has a forward-link quality threshold corresponding to a respective service node. Also, a controller determines a traffic type of the data communication services and a signal indicator of the first service node, and determines whether the signal indicator is less than the forward-link quality threshold corresponding to the first service node. In response to that the signal indicator is less than the forward-link quality threshold corresponding to the first service node, the controller switches the data communication services from the first service node to one of the second service nodes according to the traffic type.
