Problems solved by technology

However, in general, since the BCMCS system being a packet-based system can multiplex several streams and transmit the multiplexed stream on one channel instead of broadcasting one stream using only one channel, sending This method cannot be used with several streams

Embodiment Construction

[0033] Several preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, detailed descriptions of known functions and configurations thereof are omitted for conciseness.

[0034] In one embodiment of the present invention, in order to improve the reception performance of the BCMCS of the mobile station, the mobile station uses the information in the BCMC Service Parameter Message (BSPM) to extract the Common Long Code Mask (PLCM). In addition, the mobile station generates the PLCM using the auxiliary information using both the BCMC_FLOW_ID and the BCMC Service Reference Identifier (BSR_ID) transmitted using the BSPM. BSR_ID is an ID for identifying information on a plurality of broadcast programs (hereinafter referred to as 'streams') transmitted on one channel. Here, the base station can choose one of three methods, the first method is to use BSPM allocation index to generate PLCM...

Abstract

Disclosed is a method for generating a public long code mask (PLCM) so that a mobile station can receive a Broadcast / Multicast Service (BCMCS), in a mobile communication system including a base station and at least one mobile station located in a cell occupied by the base station, the BCMCS being provided from the base station to the mobile station. The PLCM is created by a combining a BCMCS flow identifier (BCMC FLOW ID) and a BCMC service reference identifier (BSR ID) matched thereto from a BCMCS service parameter message (BSPM) including information related to the BCMC FLOW IDs indicating individual flow IDs for identifying flows from respective broadcasting stations and BSR IDs matched to the BCMC FLOW IDs, the BSPM being transmitted from the base station to the mobile station over at least one channel.

Description

technical field [0001] The present invention generally relates to a broadcast / multicast service (BCMCS) method and system in a mobile communication system, and in particular to a method and system for generating channel information of the BCMCS system. Background technique [0002] Currently, standardization for supporting BCMCS other than voice service and data service is being implemented on a mobile communication system. In order to receive BCMCS, the mobile station should first detect which channel is sending the broadcast. This information about broadcasting is sent through BCMC Service Parameter Message (BSPM) or Service Parameter Message within traffic (traffic), and this message contains information for receiving broadcast programs broadcast in the current cell (hereinafter referred to as "flow" (Flow )) channel information, flow information and adjacent cell channel information. The base station determines the receptibility of the BCMCS according to the BCMC_FLOW_...
