具体实施时, 还可能存在其他确定是否响应接入请求的方式, 根据具体 情况而定。
实施时, 如图 1及图 2所示流程, 步骤 103在实施时, 由于前向信道及 反向信道均可以接入用户, 因此, 确定出剩余等效用户数可以进一步包括: 确定出前向剩余等效用户数和 /或反向剩余等效用户数。
在具体实施时, 可以根据确定出的前向剩余等效用户数和反向剩余等效 用户数二者中的任意一个, 判断是否能够接入终端, 也可以根据前向剩余等 效用户数和反向剩余等效用户数两者的结合, 判断是否能够接入终端。 例如, 当前向剩余等效用户数大于预设的最低剩余等效用户阔值时,响应接入请求, 允许终端接入, 当前向剩余等效用户数不大于预设的最低剩余等效用户阔值 时, 拒绝接入请求, 拒绝终端接入。 或者, 当反向剩余等效用户数大于预设 的最低剩余等效用户阔值时, 响应接入请求, 允许终端接入, 当反向剩余等 效用户数不大于预设的最低剩余等效用户阔值时, 拒绝终端接入。
在实施时, 前向剩余等效用户数可以按如下公式确定:
DynamicUserThresholdF= ( ThruptF/IdleT x FactorFu-ThruptF ) /BandReqF; 其中, DynamicUserThresholdF为前向剩余等效用户数, ThruptF 为前向 平均吞吐量, IdleT 为时隙占用率, FactorFu 为前向等效用户调整因子, BandReqF为前向带宽速率。其中,前向平均吞吐量 ThruptF和时隙占用率 IdleT 由基站周期上报。
实施时, 前向剩余等效用户数还可以按其他公式进行确定, 并不仅限于 本发明实施例提供的公式, 具体釆用何种公式根据具体情况而定。
实施时, 反向剩余等效用户数可以按如下公式确定:
DynamicUserThresholdR = ( ThruptR/RABIdleRatio x FactorRu - ThruptR )
/BandReqR;
其中, DynamicUserThresholdR为反向剩余等效用户数, ThruptR为后向 平均吞吐量, RABIdleRatio为 RAB ( Reverse Activity Bit, 反向激活比特)反 向空闲比, FactorRu为反向等效用户调整因子, BandReqR为反向带宽速率。 其中, RAB BIT反向空闲比 RABIdleRatio和反向平均吞吐量 ThruptR由基站 周期上报。
实施时, 反向剩余等效用户数还可以按其他公式进行确定, 并不仅限于 本发明实施例提供的公式, 具体釆用何种公式根据具体情况而定。
为保证系统中已接入用户的 QoS , 避免如现有技术中提到的: 只提出对 上行(即反向)接入用户进行接纳控制, 未对下行(即前向)接入用户进行 接纳控制的缺点, 本发明实施例提供了最优的实施例, 即, 根据前向剩余等 效用户数和反向剩余等效用户数两者的结合, 判断是否能够接入终端, 具体 实施方式如图 3所示:
步骤 301、 判断前向剩余等效用户数和反向剩余等效用户数是否均大于 预设的最低剩余等效用户阈值, 若是, 执行步骤 302, 若否, 执行步骤 303; 步骤 302、 响应接入请求, 接入终端;
步骤 303、 拒绝接入请求。
如图 3所示流程, 步骤 301在实施时, 可以只预设一个最低剩余等效用 户阔值, 前向剩余等效用户数和反向剩余等效用户数均与该预设的最低剩余 等效用户阔值进行比较, 也可以分别为前向信道设置第一最低剩余等效用户 阔值, 为反向信道设置第二最低剩余等效用户阔值, 令前向剩余等效用户数 与第一最低剩余等效用户阔值进行比较, 令反向剩余等效用户数与第二最低 剩余等效用户阔值进行比较, 当然, 第一、 第二最低剩余等效用户阔值的取 值应不小于预设的最低剩余等效用户阔值。 实施时, 预设的最低剩余等效用 户阔值的取值可以是小于 1的小数值, 也可以是大于 1的任意值, 根据实际 情况而定。
现以一个具体实施进行说明, 本例中前向剩余等效用户数和反向剩余等 效用户数及确定出两者的参数请分别参见表 1、 表 2: 表 1
Figure imgf000010_0001
设置最低剩余等效用户阔值为 1 , 由表 1及表 2数据可以毫无疑义地推 出, 前向剩余等效用户数 7和反向剩余等效用户数 6均大于最低剩余等效用 户阔值 1 , 因此, 可以响应接入请求, 接入终端。
在实施时, 当剩余等效用户数不大于预设的最低剩余等效用户阔值时, 还可以根据已存储的过载控制策略, 在已接入的终端中选择满足过载控制策 略的终端, 释放其占用的资源; 利用被释放的资源, 响应接入请求, 接入终 端。
过载控制策略可以由多种信息构成, 例如, 可以由系统中每种业务类型 的用户的前反向总吞吐量、 在线时间、 空间时间、 用户等级等信息进行配置, 配置时, 不同信息之间的优先级可以根据实际情况而定。
在实施时, 根据过载控制策略可以选择始终不释放某一种业务类型的用 户, 也可以选择某一种业务类型的用户, 释放其占用的资源, 进而能够利用 被释放的资源, 接入新用户, 这样, 即使在系统繁忙时, 仍可以选择性接收 新用户, 能够提高用户的体验与感受。
基于同一发明构思, 本发明实施例还提供了一种终端接入装置, 具体如 图 4所示, 包括接收单元 401、 解析单元 402、 第一确定单元 403和第二确定 单元 404:

在一个实施例中, 第一确定单元 403可以按如下公式确定前向剩余等效 用 户数: DynamicUserThresholdF= ( ThruptF/IdleT χ FactorFu-ThruptF ) /BandReqF;
其中, DynamicUserThresholdF为前向剩余等效用户数, ThruptF 为前向 平均吞吐量, IdleT 为时隙占用率, FactorFu 为前向等效用户调整因子, BandReqF为前向带宽速率。
