Abstract

A method and apparatus using Virtual Circuit Switching (VCS) in a new scheme are provided for allocating and employing resources by combining Circuit Switching (CS) and Packet Switching (PS), in which a base station allocates resources of a dedicated channel using the CS to a user and then transmits data on the dedicated channel. When data is not transmitted to the user, the base station allocates the allocated dedicated channel resources for resources of a shared channel and transmits data of a different user. Therefore, system capacity can be increased and a waste of communication resources can be minimized in a wireless communication system for frequently transmitting a small amount of traffic that is sensitive to a delay time.

Claims

1. A method for transmitting data in a Mobile Station (MS) of a wireless communication system, comprising:

receiving, by the MS, allocation of resources for a dedicated channel to the MS from a Base Station (BS);

monitoring a shared control channel and receiving control information for the data transmission;

determining whether resources for the dedicated channel are allocated to a different MS while also allocated to the MS through the control information;

transmitting data using remaining resources excluding the resources allocated to the different MS when the resources for the dedicated channel are allocated to the different MS; and

transmitting data using resources including the resources allocated to the different MS after expiring the allocation of the resources for the dedicated channel to the different MS when the resources for the dedicated channel are allocated to the different MS while also allocated to the MS,

wherein the control information comprises information indicating whether the resources for the dedicated channel are allocated to the different MS while also allocated to the MS.

2. An apparatus for transmitting data from a Mobile Station (MS) to a Base Station (BS) in a wireless communication system, comprising:

a control channel demodulator for demodulating a downlink signal and receiving control information relating to a shared channel;

a data channel modulator for modulating a signal to be transmitted to a radio channel and outputting the modulated signal; and

a data modulation controller for determining whether resources for a dedicated channel are allocated to a different MS while also allocated to the MS through the control information and controlling the data channel modulator to transmit data using remaining resources excluding the resources allocated to the different MS when the resources for the dedicated channel are allocated to the different MS persistently,

wherein the control information comprises information indicating whether the resources for the dedicated channel are allocated to the different MS while also allocated to the MS, and

wherein the data modulation controller controls the data channel modulator to transmit data using resources including the resources allocated to the different MS after expiring the allocation of the resources for the dedicated channel to the different MS when the resources for the dedicated channel are allocated to the different MS while also allocated to the MS.
