20090052400 | REPAIRING ERRORS IN DATA OF MBMS SERVICE - In order to guarantee service quality for a terminal for a particular point-to-multipoint service, a broadcast or multicast radio terminal system is characterized in that after the corresponding session is complete, information regarding the data that the terminal did not properly receive is informed to the UTRAN, and then the corresponding data is received upon re-transmission from the UTRAN. | 02-26-2009 |
20090097441 | METHOD AND APPARATUS FOR SELECTING MBMS RADIO BEARER TYPE - A method and apparatus for selecting a radio bearer type for providing a service to a plurality of mobile terminals according to a count of mobile terminals obtained through responses to a service response request message from a network is provided. An MBMS radio bearer type is selected according to a count that includes RRC-connected mobile terminals that still need to establish a connection in order to receive an MBMS such that the radio bearer type established is sufficient to provide the MBMS to all mobile terminals desiring to receive the service. | 04-16-2009 |
20090131063 | RRC CONNECTION REQUEST METHOD AND APPARATUS FOR MOBILE COMMUNICATIONS - A method and apparatus for transmitting a single counting end message to reject the RRC connection requests of a plurality of terminals, thus minimizing the waste of radio resources and providing a quick response to those terminals that transmitted a connection request. RRC connection request messages are sent by a plurality of terminals to a network in response to an RRC connection-required message received from the network on a first channel. Each terminal monitors a second channel for an RRC connection setup message. The network establishes connections with a predetermined number of terminals by transmitting an RRC connection setup message to each terminal on the second channel and then transmits a single RRC connection-not-required message to the plurality of terminals on the first channel. Each terminal that does not receive an RRC connection setup message on the second channel after a predetermined period of time then monitors the first channel and, after receiving the RRC connection-not-required message, terminates the network connection procedure and does not re-transmit an RRC connection request message. | 05-21-2009 |
20090190519 | METHOD AND APPARATUS FOR SELECTING MBMS RADIO BEARER TYPE - A method and apparatus for selecting a radio bearer type for providing a service to a plurality of mobile terminals according to a count of mobile terminals obtained through responses to a service response request message from a network is provided. An MBMS radio bearer type is selected according to a count that includes RRC-connected mobile terminals that still need to establish a connection in order to receive an MBMS such that the radio bearer type established is sufficient to provide the MBMS to all mobile terminals desiring to receive the service. | 07-30-2009 |
20090264133 | TERMINAL DISTRIBUTION CONTROL FOR POINT-TO-MULTIPOINT SERVICE IN WIRELESS COMMUNICATION SYSTEM - A method for controlling a user equipment (UE) capable of receiving a point-to-multipoint service in a wireless communication system comprises receiving a point-to-multipoint service and performing a cell reselection in response to completion of the receiving of the point-to-multipoint service. The cell reselection is performed among multiple frequencies. The cell reselection may be performed in response to signaling from the network. The cell reselection may be performed regardless of whether cell reselection criteria are satisfied. The cell reselection criteria may comprise at least one of a cell reselection reference value between frequencies and a cell reselection reference value within a frequency. The cell reselection criteria may be embodied in frequency layer dispersion (FLD) information. Alternatively, the cell reselection criteria may be embodied in frequency layer convergence (FLC) information. | 10-22-2009 |
20090290523 | DISCONTINUOUSLY TRANSMITTING AND RECEIVING MULTIMEDIA BROADCAST/MULTICAST SERVICE DATA IN MOBILE COMMUNICATION SYSTEM - Discontinuous transmission and reception of point-to-multipoint service data between a network and a mobile terminal is achieved by transmitting scheduling information from the network to the mobile terminal via a first common channel. The mobile terminal determines a time for receiving the service data in response to the scheduling information and discontinuously receives the service data through a second common channel. | 11-26-2009 |
20100048198 | APPARATUS AND METHOD FOR TRANSMITTING CONTROL INFORMATION IN MOBILE COMMUNICATION SYSTEM - An apparatus and method for transmitting control information in a mobile communication system transmits uplink or downlink control information required for an E-DCH transmission between MAC layers of a transmitting side and a receiving side. The MAC layer of the transmitting side divides the MAC PDU into a MAC control PDU and a MAC data PDU and transmits data through the MAC data PDU and uplink or downlink control information through the MAC control PDU to the receiving side. The MAC control PDU includes an identifier for indicating a type of a MAC PDU and a sub-identifier for discriminating a type of the corresponding MAC control PDU. | 02-25-2010 |
20100118893 | REDUCING OVERHEADS OF A PROTOCOL DATA UNIT IN A WIRELESS COMMUNICATION SYSTEM - The present invention relates to transmitting data units of a radio protocol layer, wherein one logical channel identifier is added to one or more data units belonging to one logical channel. Because only one logical channel identifier is added to the data units belonging to one logical channel in constructing a MAC-e PDU, overheads of the MAC-e PDU are reduced. Such reduction of the PDU overheads increases data throughput, which is advantageous for a high-speed data communication system, such as the HSUPA. | 05-13-2010 |
20110044274 | ESTABLISHMENT OF RADIO RESOURCE CONTROL CONNECTION IN WIRELESS COMMUNICATION SYSTEM - A method for controlling a user equipment (UE) having at least an upper layer which is above a radio resource control (RRC) layer, wherein the UE is capable of receiving a point-to-multipoint service and performing cell reselection in a wireless communication system comprises receiving an establishment parameter from the upper layer. The method also includes transmitting an RRC connection request to a network, and determining, in the RRC layer upon the cell reselection, whether to continue an RRC connection procedure to the network based on the establishment parameter. The method also includes terminating the RRC connection procedure to the network based on a result of the determining step. The RRC connection procedure may be terminated if the establishment parameter indicates a point-to-multipoint service reception. | 02-24-2011 |
