摘要:
A paging method for informing a UE of the existence or absence of control information in transmission of the control information according to the support of an MBMS in a mobile communication system. In the method, paging according to a voice and packet service and paging according to an MBMS are differentiated from each other. Accordingly, a first paging indication channel for identifying the paging according to the voice and packet service and a second paging indication channel for identifying the paging according to the MBMS are differentiated from each other and used.
摘要:
A method for managing information on user equipments (UEs) in a mobile communication system supporting an MBMS (Multimedia Broadcast/Multicast Service) service. A radio network controller (RNC) provides a packet switched (PS) service and a circuit switched (CS) service to the UEs. A UE that is in a Packet Mobility Management-Idle (PMM-Idle) mode after joining at least one MBMS service, transmits MBMS service-related information thereof to the RNC, and the RNC stores the MBMS service-related information in a first service context for the MBMS service held in the RNC, together with information on the UE.
摘要:
An apparatus and a method for allocating identifiers (IDs) which differentiate data to be transmitted in a mobile communication system supporting the transmission of packet data. The method is used for allocating identifiers to packet data by a radio network controller (RNC) so as to differentiate packet data in a mobile communication system which includes the RNC and a user equipment (UE), wherein the RNC transmits the packet data to a certain cell through at least two common channels including at least two transport channels and the UE receives the packet data through the transport channel. The method includes the steps of: determining a transport channel for transmitting received packet data; and allocating dedicated identifiers for differentiating the pack data according to the determined transport channels.

Disclosed is an uplink random access procedure in an NB-TDD (Narrow Band Time Division Duplexing) system. To achieve an acknowledgement for data transmission from a UTRAN (UMTS Terrestrial Radio Access Network), a UE selects one of a plurality of sync codes by which the UTRAN identifies UEs that request data transmission and transmits the selected sync code in a time slot of a sub-frame to the UTRAN. Then, the UE receives the sync code information, information about the arrival time of the sync code, time update information indicating a variation in the transmission time of data, and power information indicating an adjustment to a power gain in the UE from the UTRAN on an FPACH (Fast Physical Access Channel). The UE transmits the data on a P-RACH (Physical Random Access Channel) mapped from the FPACH according to the time update information and the power information.
摘要:
An HSDPA (High Speed Downlink Packet Access) communication system is disclosed. A Node B reduces a size of a field transmitting TBS (Transport Block Set) information for user data based on an MCS (Modulation and Coding Scheme) level assigned to the user data and the number of codes assigned to the user data, before transmission, instead of transmitting an intact size of the actually transmitted transport block for the user data, among TFRI (Transport Format Resource Information) transmitted to a UE (User Equipment) over a shared control channel.
摘要:
A notification method for informing a UE of an existence or absence of control information for an MBMS in a mobile communication system supporting the MBMS. In the method, the UE receives a notification indicator channel independently reporting the existence of the control information for the MBMS, confirms at least one notification indicator of the notification indicator channel, thereby confirming the existence of the control information relating to the requested MBMS. Further, a method is proposed, which can minimize an alarm due to other MBMSs.
摘要:
A method for setting up signaling connection between an RNC and an SGSN in a mobile communication system is provided. Upon receiving a service request for a particular MBMS service from a particular UE, an RNC determines whether it is necessary to set up new signaling connection for the particular MBMS service, and sets up signaling connection with an SGSN according to the determination result. The SGSN, if it desires to stop the particular MBMS service, sends a service stop request to the RNC over the signaling connection set for the particular MBMS service. The RNC then instructs at least one UE providing the particular MBMS service to stop the particular MBMS service in response to the service stop request.
摘要:
An apparatus and method for defining non-scheduled data for autonomous transmission without Node B-controlled scheduling and notifying the non-scheduled data in a mobile communication system supporting an uplink packet data service are provided. An Radio Network Controller (RNC) includes in an Enhanced Uplink Dedicated CHannel (E-DCH) setup message minimum set information indicating whether each transmittable Media Access Control-data (MAC-d) flow can be transmitted without a scheduling command from a Node B. The minimum set information may containing a maximum allowed Media Access Control-enhanced Protocol Data Unit (MAC-e PDU) size for the MAC-d flow. In the presence of data in the MAC-d flow indicated by the minimum set information, a User Equipment (UE) transmits the MAC-d flow data on the uplink even without transmission resources allowed by the scheduling command from the Node B.

摘要:
Disclosed is a power setup method for minimizing a delay time caused by an HARQ of an E-DCH when an MAC-e PDU comprising scheduling information required for using a Node B controlled scheduling is transmitted in environments supporting a packet data service through the E-DCH in an asynchronous code division multiple access (CDMA) communication system. A user equipment (UE) generates packet data for transmitting through the E-DCH, determines if signaling information is included in Quality of Service (QoS) of the packet data and the packet data, sets a power gain preset according to each QoS of the packet data, applies a determined offset value to the set power gain when the signaling information is included in the packet data, and transmits the packet data through the E-DCH according to the power gain to which the offset value has been applied.
