    摘要： The present invention discloses an uplink synchronization control method and system for the high speed shared information channel. The method includes: S102, a radio network controller assigns resources associated with the high speed downlink packet access for a user equipment and sends the information associated with the resources to Node B and the user equipment; S104, Node B configures uplink synchronization parameters for the high speed shared information channel for the user equipment using the uplink synchronization parameters which are assigned by the radio network controller for the radio link for the high speed shared information channel; the user equipment configures the uplink synchronization parameters for the high speed shared information channel of the user equipment using the uplink synchronization parameters for the uplink associated dedicated physical channel assigned by the radio network controller; S106, Node B and the user equipment send and/or receive a synchronization control commands and control the uplink synchronization process for the high speed shared information channel according to the uplink synchronization parameters for the high speed shared information channel assigned for the user equipment respectively.

    摘要： A random access method for user equipment in time division synchronization code division multiple access communication system, includes: (a) system broadcasts configured ASC and configuration information thereof to UE, the UE records these information; (b) the MAC of the UE transmits RACH transmitting request to the physical layer, the physical layer selects a RACH; (c) the UE physical layer selects randomly an uplink synchronization code and an uplink synchronization sub-channel; (d) after the UE physical layer has transmitted the selected uplink synchronization code on the uplink pilot slot correspnding to the selected uplink synchronization sub-channel, if the UE receives the access confirm information from network side, then completes the uplink synchronization, and selects PRACH to transmits message, if not, reimplements network side access. Using the invention, at the rondam access procedure, the UE of TD-SCDMA system makes the physical on UE side select a system as the ASC configuration resource, and reaches the QoS requirement and avoids the generation of conflict.
