Patent ID: 7020113

Claim:
A method for transmitting a packet at a code division multiple access (CDMA) media access control (MAC) layer control unit, the packet data being transmitted between a mobile station (MS) and a base station (BS) in a CDMA mobile communication system including the MS and the BS, the method comprising the steps of: a) when the packet is generated, by a MAC layer control unit of the MS, determining a service option of the packet; b) if the service option of the packet is a packet burst mode service, transmitting the packet via a common traffic channel (CTCH), and if the service option of the packet is a packet data mode service, by the MAC layer control unit of the MS, requesting to allocate a dedicated control channel (DCCH), receiving the DCCH, requesting to allocate a dedicated traffic channel (DTCH), receiving the DTCH, and transmitting the packet via the DTCH; and c) if the DTCH is not allocated before a control hold state timer is expired, transiting the MAC layer control unit of the MS to a suspended state or to a control hold state, wherein a probability of transiting to the suspended state equals (1−μ D )/Tc and a probability of transiting to the control hold state equals (1−μ D )(1−(1/Tc)) where the μ D denotes a request rate of the DTCH and T C denotes a control hold state timer value.
