Abstract

Method of communication between a mobile station and a base station in a mobile communication system of IMT-2000 communication network basis, which is suitable for effective transmission of various multimedia information within a given channel capacity, the method including the steps of (1) when a mobile station receives a data transmission request, providing one portion of a period of a data frame with regular number and arrangement of down link slots and up link slots and the other portion of the data frame with irregular number and arrangement of down link slots or/and up link slots depending on characteristics and amount of subscribe data to be transmitted, (2) determining a transmission type according to which a communication is executed using a competition period for determining priorities of the subscriber data, a reservation period for making a reservation for time slots for use in transmission of the subscriber data, and an assignment period for assigning a memory period according to an amount of the subscriber data, which periods are selectively and respectively included in the one portion of the data frame and in the other portion of the data frame, and (3) providing the data frame according to the transmission type and transmitting to the base station.

Claims

1. A method of communication between a mobile station and a base station in a mobile communication system comprising:

determining presence of a request for transmission of data from a mobile station, periodically;

determining a transmission type according to service options for the mobile station, if the request for transmission of data from a mobile station is present, comprising receiving the transmitted data, determining the transmission type as being the reservation transmission, executing the reservation transmission using the reservation slot if the transmission type is the reservation transmission as a result of the determination, determining the transmission type as being the assignment transmission if the transmission type is not the reservation transmission as a result of the determination, executing the assignment transmission using the assignment slot if the transmission type is the assignment transmission as a result of the determination, and executing the competition transmission using the competition slot if the transmission type is not the assignment transmission as a result of the determination; and

providing a transmission frame according to the transmission type and transmitting the transmission data to the base station, wherein;

the base station determines reception of a data frame during every competition period, and waiting for the next competition period if the data frame is not received.

2. A structure of a data frame for use in communication between a mobile station and a base station in a mobile communication system, the data frame having a static period having at least one downlink slot and at least one uplink slot, both assigned thereto regularly and alternatively and a dynamic period having downlink slots and uplink slots, both assigned thereto irregularly, the structure comprising:

a competition for determining a priority of data to be transmitted from the mobile or the base station during each of the static or the dynamic period;

a reservation period for making a reservation for a slot for use in transmission of the data;

an assignment for assigning a memory period according to an amount of the data, wherein the competition period, the reservation period and the assignment period are provided selectively, wherein, when the data frame is transmitted through the uplink slot, the data frame includes;

a first parameter for representing a content of the data frame,

a second parameter for representing a processing priority of the data frame,

a third parameter for representing a periodicity or non-periodicity of request for time slots, and

a fourth parameter for representing information on a number of required slots or periods of slot requests in requesting the time slots.

3. A structure of a data frame as claimed in claim 2, wherein a number of slots in each of the competition period, the reservation period and the assignment period is varied with characteristics of information and an amount of data to be transmitted from the base station or the mobile station.

4. A structure of a data frame as claimed in claim 2, wherein a number of slots in each of the competition period, the reservation period and the assignment period is varied with a service option for the base station or the mobile station.

5. A structure of a data frame as claimed in claim 2, wherein, when the data frame is transmitted though the up link slot, the data frame includes;

the fifth parameter for representing the frame being a pure packet data, or selectively representing the packet data and a time slot request;

a sixth parameter for representing the data frame of an initial transmission packet, representing the fata frame of a re-transmission packet, or selectively representing a first data frame of data frames of successive packets, and

a seventh parameter for selectively representing a periodicity or a non-periodicity of time slot requests.

6. A structure of a data frame as claimed in claim 2, wherein, when the data frame is a control frame transmitted though the up link slot, the data frame includes;

a parameter for representing a confirmation of reception of the data frame.
