摘要:
Disclosed are an apparatus and method for providing packet data service from a radio network controller (RNC) to user equipment (UE) in a mobile communication system. A radio bearer (RB) of a predetermined channel type is configured to compress and de-compress headers of packets passed between the RNC and the UE. The packet data service is provided from the RNC to the UE via the RB. When the channel type is changed, configuration information associated with an RB of the changed channel type is determined. Header compression (HC) context used in the RB of a previous channel type is acquired according to the configuration information and the RB of the changed channel type including the acquired HC context is configured. The packet data service is continuously provided via the RB of the changed channel type. Therefore, the invention reduces waste of radio resources that is due to a channel type change and delay that is due to system reset.

A method and apparatus for providing an MBMS (Multimedia Broadcast/Multicast Service) service to user equipments (UEs) that desire to receive the MBMS service, in a code division multiple access (CDMA) mobile communication system including a plurality of radio network controllers (RNCs), a plurality of SGSNs (Serving GPRS (General Packet Radio Service) Supporting Nodes) connected to each of the RNCs, and a plurality of the UEs wirelessly connectable to the RNCs, and providing the MBMS service to the UEs. The UEs request a desired MBMS service, and receive an MBMS service provided in response to the request. The RNCs transmit data related to the MBSM service to UEs wirelessly connected to thereto among UEs that requested the service. The SGSNs control a procedure related to the MBMS service for the UEs that requested the service. A default SGSN is individually designated for the MBMS service, and the default SGSN transmits MBMS data for the given MBMS service to UEs that requested the given MBMS service, through the RNCs.

A method and terminal apparatus for transmitting a status report comprising a received status of packet data in a mobile communication system are provided, in which whether transmission of an implicit Negative Acknowledge (NACK) signal is required for requesting retransmission of at least one non-received data packet whose sequence number is unidentified is determined, if transmission of the implicit NACK signal is required, the implicit NACK signal including a sequence number of the last packet is generated among successfully received data packets, and a status report including the implicit NACK signal is transmitted to the transmitter, and if transmission of the implicit NACK signal is not required, a status report is transmitted to the transmitter including at least one of an ACK signal comprising a sequence number of a successfully received data packet and an explicit NACK signal comprising a sequence number of a non-received data packet whose sequence number is identified.

The present invention proposes a method of making use of Cell Broadcast to support MBMS transfer service announcement or service notification transfer. The method of transferring service announcement comprises the following steps: CBC commands UTRAN connected with it by a signaling message to send service announcement; UTRAN arranges the prescribed time of sending MBMS service announcement message, adds the brief description information to the schedule message and sends the schedule message; after receiving the schedule message, UE configures physical layer thereof to prepare for receiving MBMS service announcement message. UTARN sends MBMS service announcement message at the prescribed time.
摘要:
A method for selecting a cell by a user equipment (UE) to receive a Multimedia Broadcast/Multicast Service (MBMS) service in a mobile communication system which supports the MBMS service with different frequency allocations (FAs) in the same area. In the method, a radio network controller (RNC) transmits information on an MBMS cell to the UE, and the MBMS cell information includes an MBMS offset for guaranteeing priority for cell reselection to the MBMS cell. The UE performs cell reselection using the MBMS cell information and receives the MBMS service from the reselected cell.

A method and system for delivering data are provided. The method includes sending, by a User Equipment (UE), to an evolved Node-B (eNB) a service request message for requesting data when setting up Radio Resource Control (RRC) connection using a RRC connection complete message, sending, by the eNB, the received service request message to a Mobile Management Entity (MME) using an initial UE message, sending, by the MME, an ‘initial context setup for signaling’ message that does not include information about data bearers, to the eNB, upon receiving the initial context setup message, setting up, by the eNB, Access Stratum (AS) security with the originating UE and performing, by the originating UE, Non Access Stratum (NAS) security with the MME, and upon completion of the NAS security process with the MME, transmitting, by the originating UE, the data to the MME using an uplink NAS transport message.
摘要:
A control message transmitting/receiving method in an MBMS-supporting mobile communication system. In the present invention, an RNC periodically transmits control messages related to MBMS RB setup to UEs. Thus, although a UE initially fails to receive an intended MBMS service, it can set up an MBMS RB by receiving a related retransmitted control message. Also, the RNC periodically provides information about ongoing MBMS services on a cell basis so that a UE can decide whether its requested MBMS service is in progress and request information required to set up an MBMS RB for the MBMS service to the RNC by individual signaling.

A method and an apparatus for supporting a discontinuous reception (DRX) operation in a Node B in a mobile communication system are provided. The method includes defining a second System Frame Number (SFN) where one cycle of a first SFN corresponds to one bit, transmitting information on the second SFN to a User Equipment (UE), determining a second SFN which is used to transmit a paging signal to the UE, determining a first SFN which is used to transmit the paging signal in the determined second SFN, and transmitting the paging signal to the UE at the determined first SFN.
摘要:
Apparatus and Method for transmitting control message related to a packet call service in an IP multimedia subsystem (IMS) that transmits/receives an IMS control message using a control plane to reduce a delay caused by setting of a user plane in a packet call setup process. A user equipment (UE) determines whether an IMS service is registered in response to a radio resource control (RRC) connection request. The UE sets an SRB_IMS request parameter requiring that the IMS control message be processed through a signaling radio bearer (SRB) depending on whether the IMS service is registered. The UE transmits an RRC connection request message including the SRB_IMS request parameter to a radio network controller (RNC). The UE configures an SRB_IMS entity.
摘要:
Disclosed is a method and apparatus for transmitting/receiving a packet in a mobile communication system. When upper layer packets are multiplexed into a packet whose overall size is informed via a separate path, the size of the upper layer packet is not signaled if it can be calculated from the overall size of the packet, so that the size a packet transmitted/received over a radio channel can be reduced.
