    Abstract: PURPOSE: A random access method in a mobile communication system is provided to increase the throughput of a random access channel, which terminals use to access a medium, and to solve an excessive access delay. CONSTITUTION: An AP(Access Point) detects a channel state and broadcasts channel state information through a BCH(Broadcasting CHannel) to all the terminals(S10). At this moment, the first terminal that tries to access the AP judges the broadcasted channel state information as 'idle'(S20) and transmits data to the AP(S30). The AP sets the channel state as 'busy' while the first terminal is transmitting the data. Then the AP broadcasts the changed channel state information to all the terminals(S40). At this moment, in case that the third terminal tries to access the AP, the third terminal judges the broadcasted channel state information as 'busy' and executes back-off to wait for random time(S50). If the first channel stops the transmission of the data, the AP sets the channel state as 'idle' and broadcasts the changed channel state information to all the terminals again(S60).

    Abstract: PURPOSE: A method for managing spreading codes through dual state management of a plane tree structure and a method for allocating and releasing the spreading codes by using the same are provided to adopt the plane tree structure storing an OVSF(Orthogonal Variable Spreading Factor) code tree in a one-dimensional array, and to perform the dual state management of OVSF codes, thereby eliminating the effort to search states of related codes upon allocation and release. CONSTITUTION: A state of each spreading code is divided into two fields, in order to meet an allocation rule of spreading codes. The first state field(5a) indicates a state(IDLE) of available spreading codes, a state(BUSY) of currently used spreading codes, and a state(QUASI-BUSY) showing that lower spreading codes connected to the same branch are unavailable due to use of upper spreading codes. The second state field(5b) indicates information on the number of spreading codes(#BUSY-CHILD) in a 'BUSY' state among lower spreading codes of corresponding spreading codes. Resources of a spreading code tree are managed in a plane tree structure with a one dimensional array. Accordingly, direct access into an array index is possible without passing a step of searching additional link information, when accessing the lower spreading codes and upper spreading codes.

    Abstract translation: 目的：提供一种通过对平面树结构进行双状态管理来管理扩频码的方法，以及使用该方法分配和释放扩频码的方法，以采用存储OVSF（正交可变扩频因子）码树的平面树结构 并且执行OVSF代码的双状态管理，从而消除了在分配和释放时搜索相关代码的状态的努力。 组成：每个扩展码的状态被分成两个字段，以满足扩频码的分配规则。 第一状态字段（5a）表示可用扩展码的状态（IDLE），当前使用的扩展码的状态（BUSY）和表示连接到同一分支的较低扩展码不可用的状态（QUASI-BUSY） 使用较高的扩展码。 第二状态字段（5b）指示相应扩展码的较低扩展码中处于“忙”状态的扩展码（＃BUSY-CHILD）的数目的信息。 扩展码树的资源在具有一维数组的平面树结构中进行管理。 因此，当访问较低扩展码和较高扩展码时，可以直接访问数组索引，而不需要经过搜索附加链路信息的步骤。

    Abstract: PURPOSE: A method for controlling a soft handover path in a mobile communication network is provided to set SVC connections in RNCs(Radio Network Controllers) during soft handover between the RNCs, and to previously set PVC connections in a G(Global)-RNC, thereby reducing connection setup time to supply a high-speed soft handover function. CONSTITUTION: An LIM(Link Interface Module)-N resource management processor dynamically selects usable connection identifiers among VPIs/VCIs included in an RNC of the other party, and sets connections(601). The RNC sets an operation management message path(602). A loading path is set to a basic value determined in an ATM interface, and preparation for processing a connection control request from an application program is completed(603). An LIM-N sets cells in a bypass mode(604). A G-RNC completes a connection setup function(605), and enables a remote operation management message and a control message to be transmitted(606).
