    • Disclosed is a random access method for minimizing delay for call setup, managing a random access request conflict, and adaptively allocating uplink radio resources according to the reason of an asynchronous random access from a terminal in an initial random access procedure between a base station and a terminal in a cellular mobile communication system for a packet service. The method begins with a radio resource control (RRC) layer of the terminal transferring a control primitive and an RRC connection request message to a medium access control (MAC) layer of the terminal. The MAC layer of the terminal requests the MAC layer of the base station to allocate a resource for random access. The MAC layer of the base station allocates resources upon the allocation request from the terminal and transfers the resources to the MAC layer of the terminal. The MAC layer of the terminal sets up an uplink sub-channel based on the allocated resources and transfers the RRC connection request message to the MAC layer of the base station through the uplink sub-channel. The MAC layer of the base station analyzes the RRC connection request message and requests the RRC layer of the base station to set up the RRC connection. The MAC layer of the base station transfers an RRC connection setup message to the terminal.
    • 公开了一种随机接入方法,用于最小化呼叫建立的延迟,管理随机接入请求冲突,以及根据来自终端的异步随机接入的原因,在基站和基站之间的初始随机接入过程中自适应地分配上行链路无线电资源 终端在用于分组服务的蜂窝移动通信系统中。 该方法从终端的无线资源控制(RRC)层开始,向终端的媒体接入控制(MAC)层传送控制原语和RRC连接请求消息。 终端的MAC层请求基站的MAC层分配用于随机接入的资源。 基站的MAC层根据来自终端的分配请求分配资源,并将资源传送到终端的MAC层。 终端的MAC层基于分配的资源建立上行子信道,并通过上行子信道将RRC连接请求消息传送给基站的MAC层。 基站的MAC层分析RRC连接请求消息,请求基站的RRC层建立RRC连接。 基站的MAC层向终端传送RRC连接建立消息。

    • Provided is an asynchronous random access method in a packet-based cellular system, which includes the steps of : receiving a preamble from a mobile station; checking the received preamble to see whether the mobile station includes a mobile station identifier assigned by the base station; when the mobile station does not have a mobile station identifier, allocating first scheduling information to a control information block, allocating a first response message including a mobile station identifier assigned by the base station to a downlink shared channel, and transmitting the control information block and the downlink shared channel to the mobile station; and when the mobile station includes the mobile station identifier, allocating second scheduling information to the control information block, allocating a second response message without the mobile station identifier to the downlink shared channel, and transmitting the control information block and the downlink shared channel to the mobile station.
