| 20090279469 | THE METHOD AND DEVICE FOR SENDING AND RECEIVING E-MBMS TRAFFIC DATA - The invention provides a method and device for sending MBMS traffic data based on MBMS Cell Group, the method comprises the following steps: channel coding and modulating said MBMS traffic data; determining said MBMS cell group-specific scrambling code; determining said MBMS cell-specific scrambling code; scrambling said MBMS traffic data with said MBMS cell group-specific scrambling code, and adding reference signal scrambled with said MBMS cell group-specific scrambling code and reference signal scrambled with said MBMS cell-specific scrambling code; and sending scrambled MBMS reference signal and data. With the method and the corresponding device provided by the invention, it is easy to realize RF combining or RF combining and soft combining simultaneously at UE to obtain diversity gain. | 11-12-2009 |
| 20100110961 | METHOD AND APPARATUS FOR SUPPORTING MBMS IN SYSTEM ARCHITECTURE EVOLUTION - The present invention discloses a system structure for supporting Evolved Multimedia Broadcast/Multicast Service (Evolved MBMS), comprising: a Broadcast/Multicast Service Center (BM-SC) for initiating control signaling and bearer services for Multimedia Broadcast/Multicast Service (MBMS); a System Architecture Evolved Gateway (SAE GW) for receiving MBMS service data and MBMS control signaling or service data from another network, and forwarding the received service data and control signaling; a Broadcast/Multicast Management Entity (BME) for receiving, processing and forwarding the MBMS control signaling, and determining, for each item of the service data for MBMS, an enhanced Node B (eNB) which needs to receive the control signaling; and an multicast User Plane Entity (mUPE) for receiving the MBMS service data, processing the received MBMS service data in Evolved Packet System Architecture Evolution, and forwarding the processed MBMS service data to a downstream node. | 05-06-2010 |
| 20100111110 | METHOD AND APPARATUS FOR GENERATING PDU AND BASE STATION THEREOF - Disclosed is a method and apparatus for generating a PDU and a base station thereof. The method for generating a PDU includes: segmenting an input SDU into at least one segmentation in such a manner that the at least one segmentation is distributed in at least one PDU; and setting an offset field and at least one length indicator field in a header of each PDU, wherein the offset field indicates an offset of a first segmentation of a first new SDU appearing in the PDU, and the length indicator field indicates the end of the new SDU or the segmentation of the new to SDU in the PDU. With the present invention, since a single SDU is indicated only using one LI even if it is segmented into a plurality of segmentations, and the LI indicates the end of SDU in one PDU, it is ensured that an eNB in the SFN can recover packets in case of multiple packets loss while avoiding de-synchronization during the contents transmission. | 05-06-2010 |
| 20100113056 | SCHEDULING METHOD AND SCHEDULING DEVICE FOR MBMS, AND BASE STATION INCLUDING THIS SCHEDULING DEVICE - A scheduling method for multimedia broadcast/multicast service (MBMS) is provided according to the present invention, comprising steps of: configuring service specific information and service scheduling information separately from MBMS service data to form an MCCH control message of an MBMS control channel; and transmitting the MCCH control message and the MBMS service data to a receiving end, wherein the service specific information and the service scheduling information are applied with a single-frequency network combining scheme. | 05-06-2010 |
| 20100265866 | EVOLVED MULTIMEDIA BROADCAST/MULTICAST SERVICE ACCESS GATEWAY, BASE STATION AND METHODS THEREOF - The present invention provides an Evolved Multimedia Broadcast/Multicast Service (EMBMS) access gateway supporting network multicast, comprising: receiving/responding means for receiving a Multimedia Broadcast/Multicast Service (MBMS) Session Start message from a Broadcast/Multicast-Service Center (BM-SC) and for returning a response message to the BM-SC after receiving the MBMS Session Start message; storage means for storing a mapping relationship between respective MBMS service areas (SAs) and respective base stations; determining means for determining base station(s) associated with the MBMS based on the stored mapping relationship when the receiving/responding means receives the MBMS Session Start message; and transmitting means for transmitting the MBMS Session Start message to the determined bases station(s). | 10-21-2010 |
| 20100279721 | METHODS FOR TRANSMITTING AND RECEIVING MULTIMEDIA SERVICE DATA, BASE STATION AND USER EQUIPMENT - Disclosed are methods for transmitting and receiving multimedia service data, base station and user equipment. The method for transmitting multimedia service data comprises steps of: receiving transmission order information representing the order in which a plurality of multimedia services is to be transmitted; generating schedule information including the beginning indices of the plurality of multimedia services; and transmitting data of the plurality of multimedia services based on the transmission order information and the schedule information. With the methods and equipment of the present invention, dynamic scheduling for MBMS service can be implemented in a SFN network so that power preservation of user equipment can be achieved in the case of discontinuous transmission and statistical multiplexing can be performed easily. | 11-04-2010 |
| 20110002311 | GATEWAY, BASE STATION AND METHOD FOR WINDOW-BASED CONTENT SYNCHRONIZATION - The present disclosure relates to a gateway, base station and method for window-based content synchronization technology. The gateway according the present invention comprises; a receiving unit for receiving a data packet; a window counting unit for counting the data packet, such that a predetermined number of packets forms a window, the number being a window size; a sequence number counting unit for generating a sequence number of the packet; a timestamp setting unit for setting a timestamp for the packet; and a processing unit for including the generated sequence number, the timestamp and a byte count in the packet to be transmitted. The base station according to the present invention comprises: a receiving unit for receiving a data packet; an information extracting unit for extracting a sequence number, a timestamp and byte count information from the data packet; a window counting unit for counting the received packets based on the extracted sequence number so as to form a window; and a processing unit for setting an anticipated air interface transmission time for the packets in the current window based on the extracted timestamp. The gateway or base station according to the present invention operates well with statistical multiplexing and has an improved overall performance in terms of synchronization processing delay and control packets load. | 01-06-2011 |
| 20110268018 | GATEWAY, BASE STATION, COMMUNICATION NETWORK AND SYNCHRONIZATION METHOD THEREOF - Discloses is a gateway, base station, communication network and synchronization method thereof. The method comprises: at time T | 11-03-2011 |
