Abstract: A central controller and a resource allocation method thereof for use in a cellular network are provided. The cellular network includes a user equipment and the central controller. The central controller includes a transceiver and a processor. The transceiver receives a service request signal from the user equipment. The processor is electrically connected to the transceiver and is used to determine a requested service classification of the user equipment according to the service request signal, select a selected resource allocation strategy from a resource allocation strategy set according to the requested service classification, and allocate resources to the user equipment according to the selected resource allocation strategy. The central controller and the user equipment transmit data by the resource.

Abstract: A base station and a user equipment authentication method thereof are provided. The base station is for use in a wireless network system. The wireless network system includes the user equipment. The base station receives a login request message from the user equipment, and determines that the user equipment is recorded in a black list according to the login request message. The base station further rejects login of the user equipment according to the black list.

Abstract: A femtocell and a resource control method thereof are provided. The femtocell comprises a processor and a transceiver. The processor is configured to determine that a service resource of the femtocell reaches a saturation value, reduce a transmitting power of a primary common pilot channel power signal, and set a parameter of a system information block message as a barred state. The transceiver is electrically connected to the processor and configured to transmit the primary common pilot channel power signal and the system information block message.

Abstract: A mobile communication method for a mobile originating (MO) side communicating with a mobile terminating (MT) side is disclosed. A first media gateway (MGW) is included in the communication network serving the MO side, and a second MGW is included in the communication network serving the MT side. The mobile communication method includes: after a SETUP message is received from the mobile originating side, determining if the mobile originating side is in Circuit Switching (CS) Domain. If the MO side is under CS domain, determining if the MT side is under CS domain. When the MO side and the MT side are both under CS domain, voice communication signals between the MO side and the MT side are transmitted with CS bearer between the first MGW and the second MGW.
