An intermittent reception control apparatus controls intermittent reception in communication between a base station apparatus and mobile station apparatuses. The intermittent reception control apparatus comprising a control unit that generates DRX parameters, which are intermittent reception parameters, and transmits the generated DRX parameters to the mobile station apparatuses. Further, the DRX parameters include information on the timing at which to cause the mobile station apparatuses to enter an active state and are common to all of the mobile station apparatuses, where the active state is a state where reception of signals transmitted from the base station apparatus is enabled. The intermittent reception control apparatus further comprising a scheduler that transmits to the mobile station apparatuses a DRX command that operates to force these apparatuses to enter an inactive state.

Intermittent reception control apparatus, computer-readable recording medium, and intermittent reception control method

When communications between mobile terminals MSand MSare terminated, a TRAUjudges whether the communications between mobile terminals MSand MSare synchronous and notifies the mobile terminal MSof this information through both a base station control center BSCand a base station BTS. The mobile terminal MSstores this information in relation to both the dial number of the mobile terminal MSand a voice-encoding type used in communications with the mobile terminal MS. Similarly, a TRAUtransmits the same information to the mobile terminal MSand the mobile terminal MSstores this information along with the dial number of the mobile terminal MSand a voice-encoding type. When the mobile terminals MSand MScommunicate the second time, communications are conducted using another voice-encoding type if the communications are asynchronous and using the previous voice-encoding type if the communications are synchronous, based on the information stored in this way.
