Abstract

Abstract A method for realizing multicast service in a mobile communication system simultaneously provides various multicast services to the plurality of users through one common channel. The method for realizing multicast service in a mobile communication system includes the steps of: (a) allocating a multicast service identifier to each mobile station in a multicast server; (b) loading control and data frame areas according to various multicast service on one common channel down-linked in the multicast server, and transmitting the control and data frame areas; (c) searching a control frame area of the transmitted common channel in each mobile station, and detecting a control frame area corresponding to the allocated multicast service identifier; and (d) receiving each multicast service corresponding to a data frame area according to the detected control frame area.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 105 words
A method for realizing multicast service in a mobile communication system, comprising the steps of: (a) allocating a multicast service identifier to each mobile station in a multicast server; (b) loading control and data frame areas according to various multicast service on one common channel down-linked in the multicast server, and transmitting the control and data frame areas; (c) searching a control frame area of the transmitted common channel in each mobile station, and detecting a control frame area corresponding to the allocated multicast service identifier; and (d) receiving each multicast service corresponding to a data frame area according to the detected control frame area.
Claim 2
Dependent Claim 25 words
A method for realizing multicast service in a mobile communication system according to claim 1, wherein the common channel is a downlink shared channel (DSCH).
Claim 3
Dependent Claim 33 words
A method for realizing multicast service in a mobile communication system according to claim 2, wherein the downlink shared channel (DSCH) is divided into a control frame area and a data frame area.
Claim 4
Dependent Claim 41 words
A method for realizing multicast service in a mobile communication system according to claim 3, wherein the control frame area and the data frame area is made of a period having the same transmission block and the same transmission time interval.
Claim 5
Dependent Claim 22 words
A method for realizing multicast service in a mobile communication system according to claim 4, wherein the period is 10 miliseconds (ms).
Claim 6
Dependent Claim 39 words
A method for realizing multicast service in a mobile communication system according to claim 2, wherein the downlink shared channel (DSCH) is an additional downlink shared channel (DSCH) comprised of a control frame area and a data frame area.
Claim 7
Independent Claim 83 words
A method for realizing multicast service in a mobile communication system, comprising the steps of: monitoring at a mobile station a control frame area of a downlink shared channel (DSCH) down-linked from a multicast server; detecting a multicast service identifier in the control frame area; performing a switching operation to a downlink shared channel (DSCH) having a multicast data, if the multicast service identifier is detected; and receiving a multicast data in a data frame area of the downlink shared channel (DSCH) switched.
