摘要： A method for allocating reverse traffic channels at the time of handoff in a CDMA communication system, comprises the steps of: upon receiving a handoff request from a control station at a target base station, setting a Search Center Offset (SCO) to a Round Trip Delay (RTD) value received from a serving base station, and setting a searching area (S±β) to an area wider than a reference searching area (S) in view of an error (β) in the RTD value; dividing the searching area into a number of sub-areas, and allocating reverse traffic channels such that each reverse traffic channel covers its corresponding sub-area; monitoring the reverse traffic channels to determine whether a mobile station has been acquired; and if the mobile station has been acquired, releasing the remaining reverse traffic channels except for the reverse traffic channel which has acquired the mobile station.

摘要： There is provided a method for allocating multiple access channels at the time of call setup in a mobile communication system, wherein the method comprises the steps of: informing a mobile station that a modem of a base station is using one access channel; dividing a coverage area of the base station into a number of sub-areas; allocating a number of access channels such that each of the access channels covers its corresponding sub-area; monitoring the access channels to determine whether an access probe transmitted from the mobile station has been acquired; and if the access probe has been acquired, outputting the acquired access probe to the channel card and releasing the remaining access channels. The method reduces a call setup time and improves the call setup services by dividing a coverage area of a base station into several sub-areas according to a distance from the base station and allocating each of the access channels to the corresponding sub-area so that the search window size of each access channel diminishes.
摘要翻译：提供了一种在移动通信系统中在呼叫建立时分配多个接入信道的方法，其中该方法包括以下步骤：向移动台通知基站的调制解调器正在使用一个接入信道; 将基站的覆盖区域划分为多个子区域; 分配多个接入信道，使得每个接入信道覆盖其对应的子区域; 监视接入信道以确定是否已经获取了从移动台发送的接入探测; 并且如果已经获取了访问探针，则将所获取的访问探针输出到信道卡并释放剩余的访问信道。该方法通过根据距离基站的距离将基站的覆盖区域划分成若干子区域并将每个接入信道分配给对应的子区域来减少呼叫建立时间并改善呼叫建立业务，从而使得每个访问信道的搜索窗口大小减少。

摘要： A method of erasing a semiconductor memory device comprises grouping a plurality of word lines of each memory block into at least two groups based on intensity of disturbance between neighboring word lines; performing an erase operation by applying a ground voltage to all word lines of a selected memory block and by applying an erase voltage to a well of the selected memory block; and first increasing the ground voltage of one group of the groups to a positive voltage during the erase operation.
