本发明提供一种网络设备, 如图 1 所示, 本实施例所揭示的网络设备 120包括接收单元 121、 处理单元 122以及发送单元 123。 本实施例的网络 设备 120用于与终端 330建立网络连接, 该网络包括第一网络, 终端 330 包括终端接收单元 331和终端发送单元 332。
其中, 终端发送单元 332发出请求接入的第一信号, 接收单元 121获 取第一信号并获取第一网络的负载, 处理单元 122根据负载配置接入条件, 以及根据第一信号获取终端 330 的测量量, 并将测量量与接入条件进行比 较, 若测量量符合接入条件, 则发送单元 123向终端 330发送第二信号, 终端接收单元 331接收该第二信号, 并据此接入第一网络, 从而建立网络 连接。 其中, 第一网络为无线局域网络, 本实施例优选为 WiFi网络。
在本实施例中, 获取的终端 330的测量量可以为通过对终端 330的第 一信号解析获得的信号强度(RSSI, Received Signal Strength Indicator ), 也 可以为通过 GPRS等定位方法获得的终端 330与网络设备 120的间距, 即 终端距离, 或者两者共存, 当然也可以是其他任何能够实现本发明之目的 的任何终端信息, 例如可设置测量量为第一信号的 SNR ( Signal/Noise, 信 噪比)、 SINR( Signal to Interference plus Noise Ratio,信号与干扰力口噪声比)、 RSRP ( Reference Signal Receiving Power , 参考信号接收功率)、 RSRQ ( Reference Signal Receiving Quality , 参考信号接收质量 )。
在本实施例中, 由于测量量为终端 330的信号强度和 /或终端距离, 相 应地终端 300 的测量量符合接入条件包括测量量大于或等于预设测量量阈 值、 测量量的波动阈值小于或等于预设测量量波动阈值或测量量的波动频 率小于或等于预设测量量波动频率。 终端 330 的测量量不符合接入条件包 括测量量小于预设测量量阈值、 测量量的波动阈值大于预设测量量波动阈 值或测量量的波动频率大于所述预设测量量波动频率。
其中, 测量量的波动阈值表示多次采样的终端 330 的测量量的差值的 平均值, 例如三次采样中相邻两次的差值为 10和 8, 则平均值为 9, 预设 测量量阈值表示预先设置的限定终端 330 可以接入第一网络的一固定数值 或固定范围的阈值, 若预设测量量波动阈值为 7, 则终端 330的测量量波动 阈值大于预设测量量波动阈值, 即不符合接入条件。
测量量的波动频率表示多次采样的终端 330 的测量量的变化频率的平 均值, 例如五次采样中相邻两次的差值分别是 1、 5、 15和 5 , 则变化频率 的平均值为 ((5-1 ) + ( 15-3 ) + ( 5-15 ) ) ÷3-2 , 预设测量量波动频率表示 预先设置的限定终端 330可以接入第一网络的一固定频率数值或取值范围, 若该取值范围为 1~3 ,则测量量的波动频率属于预设测量量波动频率的取值 范围, 即符合接入条件。
需要说明的是, 本发明接入条件包括的测量量的波动阈值和测量量的 波动频率, 仅供说明举例, 并不仅限于此。
本实施例中, 第二信号优选为类似现有技术中的探查响应帧 (Probe Response )的帧信号, 在其他实施例中, 终端 330发出的第一信号还可以包 含其他管理帧、 控制帧或数据帧, 比如 GAS Request, Association Requesto 另外, 可以理解的是, 本实施例的第二信号为终端 330向网络设备 120发 送的第一信号的一种回复和 /或确认信息, 此时其对应的包含有各种帧, 比 如 ACK ( Acknowledgement, 确认字符)、 Probe Response、 GAS Response 、 Association Response。
接收单元 331在获取该第二信号后即可使得终端 330与第一网络建立 网络连接, 具体的连接方式可参见现有技术, 此处不再赘述。 另外, 本发 明全文所提及的终端 330以手机为例,当然不局限于手机,可以是具有 WiFi 网络接入功能的任何终端, 包括平板电脑(PAD )等。
基于上述, 本实施例通过网络设备 120将待接入终端 330的测量量与 根据第一网络配置的接入条件相比较, 在测量量符合接入条件时允许终端 330接入,从而能够保证接入第一网络的终端 330的通信质量, 并提升第一 网络的频谱效率。

本发明还提供一种网络设备的负载控制方法, 请参见图 5 的本发明第 一实施例的负载控制方法的流程图。 如图 5 所示, 本实施例所揭示的负载 控制方法基于图 1所示的网络设备 120, 该方法包括:
步骤 S11 : 网络设备 120配置第一网络的接入条件。
具体为, 网络设备 120配置终端 330能够接入第一网络的接入条件。 步骤 S12: 网络设备 120从终端 330接收第一信号, 并根据第一信号获 取终端 330的测量量。
步骤 S13: 网络设备 120判断测量量是否符合接入条件。
步骤 S14: 若测量量符合接入条件, 则网络设备 120向终端 330发送第 二信号, 终端 330根据第二信号接入第一网络。
步骤 S15: 若测量量不符合接入条件, 则网络设备 120 不向终端 330 发送第二信号, 以拒绝终端 330接入第一网络。
在本实施例的步骤 S12中, 第一信号可由图 2所示的网络接入点 125 获取或由第一网络控制器 130获取。 其中, 第一网络控制器 130获取第一 信号的方式可由网络接入点 125透传至第一网络控制器 130而得到的。
本发明的下述实施例中均以信号强度代表测量量、 接入阈值代表接入 条件、 WiFi网络代表第一网络进行描述。 进一步地, 信号强度可由网络接 入点 125对其接收的第一信号进行解析获得, 以便后续的网络接入点 125 将信号强度与接入阈值进行比较。
或者, 网络接入点 125在获得信号强度后根据预设条件对该信号强度 进行判断, 并将满足该预设条件的信号强度发送至第一网络控制器 130, 以 使第一网络控制器 130 比较信号强度和接入阈值, 其中预设条件可以为步 骤 S11中配置的接入条件, 也可以是根据实际需要设置的其他条件。
再或者, 网络接入点 125在获得信号强度后将全部的信号强度直接发 送至第一网络控制器 130,以使第一网络控制器 130将信号强度和接入阈值 进行比较。 又或者, 信号强度由第一网络控制器 130直接对其自身接收的第一信 号进行解析获得, 并将信号强度和接入阈值进行比较。 需要说明的是, 根 据接收的第一信号获取信号强度的具体过程可参照现有技术, 比如直接测 量第一信号的信号强度、 对第一信号的信号强度进行预定算法 (如, 加权 平均) 的运算或者解析第一信号的数据包, 直接读取相应字段。
网络设备 120通过 WiFi网络系统或其运行的硬件控制程序获取 WiFi 网络的负载, 而后根据预先定义的负载与接入阈值的对应关系配置接入阈 值, 其中, 负载可以是 WiFi网络中网络接入点 AP的空口负载, 如占空比、 已连接终端的数目, 也可以是 AP设备的自身负载, 如流量、 CPU 内存的 消耗, 还可以是 WiFi网络中接入点控制器 AC的负载, 如流量、 CPU内存 的消耗。 另外, 接入阈值可以是单一阈值, 例如 -80dbm, 只要待接入的终 端 330的测量量大于或等于 -80dbm, 即允许终端 330与 WiFi网络建立网络 连接。
在步骤 S12中, 网络设备 120从终端 330获取第一信号, 即终端 330 获取周围的 WiFi网络信号的方式有两种:
一种是被动扫描, 是指通过侦听网络设备 120 定期发送的信标帧 ( Beacon )发现周围的 WiFi网络。 提供 WiFi网络服务的网络设备 120会 周期性发送信标帧, 因此终端 330可以定期在支持的信道列表监听信标帧, 以获取周围的 WiFi网络信号。 需要说明的是, 当用户需要终端 330节省电 量时, 可以优选使用被动扫描方式。
另一种是主动扫描,终端 330在开启运行 WiFi网络搜寻功能的过程中, 会定期地搜索周围的 WiFi网络信号。 终端 330定期地在其支持的信道列表 中主动发送一个包含有 SSID ( Service Set Identifier, 服务集标识) 的探测 请求帧 ( Probe Request ), 通过收到的网络设备 120回复的探查响应帧, 以 获取 WiFi网络信号。
需要说明的是, 本实施例的步骤 S11与步骤 S12之间没有联系, 可以 先执行步骤 S11 ,然后再执行步骤 S12;或先执行 S12,然后再执行步骤 S11 , 本发明实施例对此并不进行限定。
在其他实施例的步骤 S15 中, 若测量量不符合接入条件, 还可以设置 网络设备 120向终端 330发送第二信号, 以告知终端 330其被拒绝接入第 一网络。 其中, 第二信号可以由图 2所示的第一网络控制器 130发送, 也 可以由第一网络控制器 130向网络接入点 125发送一指令, 再由网络接入 点 125发送。
本实施例通过网络设备 120将待接入终端 330的测量量与根据网络接 入点 125 的负载配置的接入条件相比较, 在测量量符合接入条件时允许终 端 330接入, 从而能够保证接入第一网络的终端 330的通信质量, 并提升 第一网络的频谱效率。
本发明还提供第二实施例的负载控制方法, 其在第一实施例所揭示的 负载控制方法的基础上进行详细描述。 在步骤 S11 中, 配置的接入阈值可 以是在由人工配置的固定列表, 一旦配置即不能更改, 即根据预先定义的 负载与接入阈值的对应关系配置接入阈值, 其中设置对应关系中的负载包 括第一负载、 第二负载以及第三负载, 且第一负载〉第二负载〉第三负载, 网络设备 120配置的接入阈值包括与第一负载对应的第一阈值、 与第二负 载对应的第二阈值、 与第三负载对应的第三阈值, 且第一阈值〉第二阈值> 第三阈值。 具体可参见如下表 1所示:
Figure imgf000020_0001
Figure imgf000020_0002
在配置接入阈值时, 若网络接入点 125 的负载大于或等于第一负载 60% , 则网络设备 120配置接入阈值为第一阈值 -60dbm。 若网络接入点 125 的负载大于或等于第二负载 30%且小于第一负载 60%, 则网络设备 120配 置接入阈值为第二阈值 -70dbm。 若网络接入点 125的负载大于或等于第三 负载 0%且小于第二负载 30% , 则网络设备 120配置接入阈值为第三阈值 -80dbm。 其中, 第一阈值 -60dbm >第二阈值 -70dbm >第三阈值 -80dbm, 表 示网络接入点 125的负载越高, 网络设备 330配置的接入阈值越高, 允许 接入的终端 330的测量量越高, 接入终端 330的范围越小。
需要说明的是, 本实施例揭示的三个负载及对应的三个接入阈值, 以 及上述表 1 中相应的具体数值, 仅供说明举例, 在其他实施例中, 本领域 技术人员可以根据实际需要进行其他设置, 只需满足多个负载与多个接入 阈值的——对应关系, 并使得负载越高, 网络设备 120 配置的接入阈值越 高, 允许接入的终端 330的测量量越高即可。
本发明还提供第三实施例的负载控制方法, 其在第一实施例所揭示的 负载控制方法的基础上进行详细描述。 本实施例基于图 2所示实施例的网 络设备 120, 如图 6所示, 所揭示的负载控制方法包括:
步骤 S31 : 网络接入点 125获取第一网络的负载。
步骤 S32: 网络接入点 125根据负载配置接入阈值。
其中, 可在上电时, 优选由人工在网络接入点 125 中预先设置负载与 接入阈值的对应关系, 再由网络接入点 125根据该对应关系进行配置, 该 对应关系可以为上述负载控制方法的第一实施例中揭示的多个负载与单一 接入阈值的对应关系, 也可以为第二实施例中揭示的多个负载与多个接入 阈值——对应关系。
步骤 S33: 网络接入点 125从终端 330获取第一信号, 并根据第一信号 获取终端 330的信号强度。
步骤 S34: 网络接入点 125将信号强度与接入阈值进行比较。
步骤 S35: 若信号强度大于或等于接入阈值, 则网络接入点 125向终端 330发送第二信号, 以允许终端 330接入。
本发明还提供第四实施例的负载控制方法, 其在第三实施例所揭示的 负载控制方法的基础上进行详细描述。 本实施例的网络设备基于图 2所示 实施例的网络设备 120,且本实施例的负载控制方法与图 6所示第三实施例 的不同之处在于:
在步骤 S31中,由第一网络控制器 130获取第一网络的网络接入点 125 的负载, 在步骤 S32中, 由第一网络控制器 130根据网络接入点 125的负 载配置接入阈值, 具体而言, 可在上电时, 第一网络控制器 130根据预先 设置的负载与接入阈值的对应关系进行配置。 在完成接入阈值的配置后, 第一网络控制器 130将接入阈值发送至网络接入点 125 , 再由网络接入点 125将待接入终端 330的信号强度与接入阈值进行比较。
本发明还提供第五实施例的负载控制方法, 其在第四实施例所揭示的 负载控制方法的基础上进行详细描述。 本实施例的负载控制方法与第四实 施例的不同之处在于:
在完成接入阈值的配置后, 第一网络控制器 130将接入阈值发送至网 络接入点 125 ,再由第一网络控制器 130将待接入终端 330的信号强度与接 入阈值进行比较。
本发明还提供第六实施例的负载控制方法, 其在第四实施例所揭示的 负载控制方法的基础上进行详细描述。 在本实施例的步骤 S35 中, 若信号 强度大于或等于接入阈值, 则网络接入点 125将第一网络的负载发送至第 一网络控制器 130, 第一网络控制器 130根据第一网络的负载均衡, 并通过 网络接入点 125向终端 330发送第二信号, 以允许终端 330接入第一网络 的网络接入点 125。
其中, 负载均衡为第一网络控制器 130允许终端 330通过第一网络的 多个网络接入点中负载最小的一个网络接入点接入第一网络。 具体而言, 在第一网络设置有多个网络接入点 125 时, 若信号强度大于或等于接入阈 值, 则每一个网络接入点 125将其负载发送至第一网络控制器 130, 第一网 络控制器 130选取负载最小的网络接入点 125 ,并通过其向终端 330发送第 二信号, 以允许终端 330接入该负载最小的网络接入点 125。
值得注意的是, 在其他实施例中, 还可以设置一额定负载, 若第一网 络控制器 130选取的负载最小的网络接入点 125的负载仍大于或等于该额 定负载, 则拒绝终端 330接入第一网络。
本发明还提供第七实施例的负载控制方法, 其在第六实施例所揭示的 负载控制方法的基础上进行详细描述。 本实施例的负载控制方法与第四实 施例的不同之处在于:
在本实施例的步骤 S35中, 在网络接入点 125将第一网络的负载发送 至第一网络控制器 130,第一网络控制器 130根据第一网络的负载均衡之后, 通过第一网络控制器 130向终端 330发送第二信号, 以允许终端 330接入 第一网络的网络接入点 125。
本发明还提供第八实施例的负载控制方法, 其在第一实施例所揭示的 负载控制方法的基础上进行详细描述。 在本实施例中, 网络设备基于图 3 所示实施例的网络设备 120, 如图 7所示, 揭示的负载控制方法包括:
步骤 S51 : 第一网络接入点 141获取第一网络接入点 141的负载, 第二 网络接入点 142获取第二网络接入点 142的负载。
步骤 S52:第一网络接入点 141根据第一网络接入点 141的负载配置第 一接入阈值, 并将该第一接入阈值发送至第一网络控制器 130。
步骤 S53:第二网络接入点 142根据第二网络接入点 142的负载配置第 二接入阈值, 并将该第二接入阈值发送至第一网络控制器 130。
步骤 S54:第一网络控制器 130根据第一网络接入点 141的负载和第二 网络接入点 142的负载更新第一接入阈值和第二接入阈值。
步骤 S55: 第一网络控制器 130从终端 330获取第一信号, 并根据第一 信号获取终端 330的信号强度。
步骤 S56:第一网络控制器 130将信号强度与更新后的接入阈值进行比 较。
步骤 S57: 若信号强度大于或等于更新后的第一接入阈值, 则第一网络 控制器 130向终端 330发送第二信号, 以允许终端 330接入第一网络接入 点 141。
在本实施例的步骤 S54和步骤 S64中, 由第一网络控制器 130比较第 一网络接入点 141的负载和第二网络接入点 142的负载的大小。 若第一网 络接入点 141的负载大于第二网络接入点 142的负载, 则第一网络控制器 130对第一接入阈值和第二接入阈值进行更新, 以使得第一网络接入点 141 更新后的接入阈值大于第一接入阈值, 同时第二网络接入点 142 更新后的 接入阈值小于第二接入阈值。 若第一网络接入点 141 的负载小于第二网络 接入点 142的负载, 则第一网络控制器 130对第一接入阈值和第二接入阈 值进行更新, 以使得第一网络接入点 141 更新后的接入阈值小于第一接入 阈值, 同时第二网络接入点 142更新后的接入阈值大于第二接入阈值。 若 第一网络接入点 141的负载等于第二网络接入点 142的负载, 表示待接入 的终端 330 可以接入第一网络和第二网络中的任意一个, 则第一网络控制 器 130不对第一接入阈值和第二接入阈值进行更新。
其中, 上述更新具体而言, 第一网络控制器 130产生更新值, 并根据 该更新值对第一接入阈值和第二接入阈值进行运算。 在更新值为绝对值时, 第一网络控制器 130可将该绝对值直接替换第一接入阈值或第二接入阈值, 以得到更新后的接入阈值。 在更新值为相对值时, 第一网络控制器 130可 将该绝对值与第一接入阈值或第二接入阈值相加, 以得到更新后的接入阈 值。 应理解, 在其他实施例中, 第一设备还可产生第一更新值和第二更新 值, 而后将第一更新值与第一接入阈值进行运算、 将第二更新值与第二接 入阈值进行运算, 以得到更新后的接入阈值。
本发明还提供第九实施例的负载控制方法, 其在第八实施例所揭示的 负载控制方法的基础上进行详细描述。 本实施例与图 7所示第八实施例的 不同之处在于:
在步骤 S51中, 由第一网络控制器 130获取第一网络接入点 141的负 载和第二网络接入点 142的负载。 在步骤 S52和步骤 S53中, 由第一网络 控制器 130更新第一接入阈值和第二接入阈值。
此外, 应理解, 本实施例和上述第八实施例仅仅是以第一网络及其第 一网络接入点 141和第二网络接入点 142 ,这两个网络接入点为例进行说明, 在其他实施例中, 还可设置第一网络包括多个网络接入点。
上述第八实施例和第九实施例, 能够在相邻的多个网络组网时, 对多 个网络接入点的接入阈值进行对应更新, 能够减小高负载的网络接入点的 接入阈值、 增大低负载的网络接入点的接入阈值, 使得终端 330优先接入 负载较低的网络接入点, 从而实现网络资源的优化配置, 确保终端 330与 接入网络的通信质量, 进而提升网络接入点的频谱效率。
本发明还提供第十实施例的负载控制方法, 其在第一实施例所揭示的 负载控制方法的基础上进行详细描述。 在本实施例中, 网络设备基于图 4 所示实施例的网络设备 120。如图 8所示, 本实施例所揭示的负载控制方法 包括:
步骤 S71:第一网络控制器 130获取第一网络的网络接入点 125的负载, 第二网络控制器 210获取第二网络的负载。
步骤 S72: 第二网络控制器 210根据第二网络和第一网络的拓朴关系、 第二网络的负载以及第一网络的网络接入点 125的负载更新接入阈值。
步骤 S73: 网络接入点 125从终端 330获取第一信号, 并根据第一信号 获取终端 330的信号强度。
步骤 S74: 网络接入点 125将信号强度与接入阈值进行比较。
步骤 S75: 若信号强度大于或等于接入阈值, 则网络接入点 125向终端 330发送第二信号, 以允许终端 330接入网络接入点 125。
在本实施例中, 拓朴关系是指第二网络覆盖第一网络, 二者重叠覆盖 组网。 第二网络优选为覆盖第一网络(WiFi网络) 的蜂窝网络, 第二网络 控制器 210优选为无线网络控制器 RNC,或者基站 eNB、基站控制器 BSC、 信令网关 SGW中的任意一个。 另外, 步骤 S72中第二网络控制器 210对网 络接入点 125的接入条件的更新, 可按照下表 2进行:
Figure imgf000025_0001
参照表 2,在步骤 S72中, 第一网络的网络接入点 125的负载为轻且第 二网络的负载为轻时, 第二网络控制器 210增大接入阈值, 以使得更新后 的接入阈值大于更新前的接入阈值。 第一网络的网络接入点 125 的负载为 轻且第二网络的负载为重时, 第二网络控制器 210减小接入阈值, 以使得 更新后的接入阈值小于更新前的接入阈值。 第一网络的网络接入点 125 的 负载为重且第二网络的负载为轻时, 第二网络控制器 210增大接入阈值, 以使得更新后的接入阈值大于更新前的接入阈值。 第一网络的网络接入点 125的负载为重且第二网络的负载为重时,第二网络控制器 210不调整接入 阈值, 以使得更新后的接入阈值等于更新前的接入阈值。
进行更新的步骤具体而言, 第一网络控制器 130将获取的第一网络的 网络接入点 125的负载发送至第二网络控制器 210,第二网络控制器 210根 据该负载和自身获取的第二网络的负载产生更新值并将其下发, 其中更新 值为绝对值或相对值, 第一网络控制器 130接收该更新值并对第一网络的 网络接入点 125 的接入阈值进行更新, 具体更新过程与上述实施例八的更 新过程类似, 此处不再赘述。
在其他实施例中, 第二网络控制器 210产生更新值后, 并不将其下发 给第一网络控制器 130,而是由其自身对第一网络的网络接入点 125的接入 阈值进行更新,然后将更新后的接入阈值下发给第一网络控制器 130。并且, 在更新值为绝对值时, 第二网络控制器 210可将该绝对值直接替换更新前 的接入阈值, 以得到更新后的接入阈值。 在更新值为相对值时, 可通过如 下公式获取更新后的接入阈值:
接入阈值=调整步长 * (参考负载-第二网络控制器的负载)
其中, 参考负载为预先设置的第二网络的额定负载, 调整步长的取值 范围为 (0, 20] , 本实施例优选默认值为 5 , 单位是 db。
另外, 在其他实施例的步骤 S72中, 可以由第一网络控制器 130根据 拓朴关系、 第二网络的负载以及网络接入点 124的负载更新接入条件。
本实施例, 能够在具有拓朴关系的多个网络组网时, 对被覆盖的网络 的接入阈值进行更新, 通过减小高负载的网络接入点的接入阈值或增大低 负载的网络接入点的接入阈值, 使得终端 330接入负载最佳的网络, 从而 实现网络资源的优化配置, 确保终端 330与接入网络的通信质量, 进而提 升多个网络的网络接入点的频谱效率。
本发明还提供第十一实施例的负载控制方法, 其在第一实施例所揭示 的负载控制方法的基础上进行详细描述。 在本实施例中, 网络设备基于图 2 所示实施例的网络设备 120。如图 9所示, 本实施例所揭示的负载控制方法 包括:
步骤 S81: 网络接入点 125获取网络接入点 125的负载。
步骤 S82: 网络接入点 125从终端 330获取第一信号, 并根据第一信号 获取终端 330的信号强度。
步骤 S83: 网络接入点 125判断第一信号中是否携带用户等级, 并根据 网络接入点 125的负载和用户等级配置接入阈值。
步骤 S84: 网络接入点 125将信号强度与接入阈值进行比较。
步骤 S85: 若信号强度大于或等于接入阈值, 则网络接入点 125向终端 330发送第二信号, 以允许终端 330接入。
在本实施例的步骤 S83中, 若网络接入点 125通过解调判断第一信号 携带用户等级, 则根据网络接入点 125 的负载和用户等级配置接入阈值。 若判断第一信号没有携带用户等级, 则网络接入点 125通过第一网络控制 器 130查询发出第一信号的终端 330的用户等级, 并根据网络接入点 125 的负载和用户等级配置接入阈值。 其中, 用户等级、 网络接入点 125 的负 载和接入阈值的相互之间的对应关系, 可参见如下表 3所示:
Figure imgf000027_0001
即, 若网络接入点 125获取网络接入点 125的负载为 60% , 且判断第 一信号携带用户等级为高, 则配置接入阈值为 -80dbm。 若网络接入点 125 获取网络接入点 125的负载为 60% , 且判断第一信号携带用户等级为低, 则配置接入阈值为 -60dbm。 若网络接入点 125获取网络接入点 125的负载 为 30%, 且判断第一信号携带用户等级为高, 则配置接入阈值为 -90dbm。 若网络接入点 125获取网络接入点 125的负载为 30%, 且判断第一信号携 带用户等级为低, 则配置接入阈值为 -70dbm。 若网络接入点 125获取网络 接入点 125的负载为 0% , 且判断第一信号携带用户等级为高, 则配置接入 阈值为 -∞dbm, 即不设置接入阈值。若网络接入点 125获取网络接入点 125 的负载为 0% , 且判断第一信号携带用户等级为低, 则配置接入阈值为 -80dbm。
需要说明的是, 本实施例中将负载仅设置为三个, 将用户等级仅划分 为两级, 以及上述表 3 中接入阈值的具体数值, 仅供说明举例, 在其他实 施例中, 本领域技术人员可以根据实际需要将用户等级进行其他划分, 只 需满足在同一负载级别, 用户等级越高, 对应的接入阈值越低即可。
应理解, 在其他实施例中, 还可以对所有用户等级为高时, 网络接入 点 125不设置接入阈值, 即接入阈值为 -∞, 同时仅对用户等级为低时设置 网络接入点 125的接入阈值。
本发明还提供第十二实施例的负载控制方法, 其在第一实施例所揭示 的负载控制方法的基础上进行详细描述。 本实施例与上述第十一实施例不 同之处在于:
在步骤 S81中,由第一网络控制器 130获取第一网络的网络接入点 125 的负载。 在步骤 S83中, 由第一网络控制器 130判断第一信号中是否携带 用户等级, 并根据网络接入点 125 的负载和用户等级配置接入阈值。 即, 若第一网络控制器 130通过解调判断第一信号携带用户等级, 则根据网络 接入点 125 的负载和用户等级配置接入阈值。 若判断第一信号没有携带用 户等级, 则第一网络控制器 130通过自身查询发出第一信号的终端 300的 用户等级, 并根据网络接入点 125的负载和用户等级配置接入阈值。
另外, 本实施例的配置接入条件的步骤具体而言, 第一网络控制器 130 产生更新值, 在更新值为绝对值时, 第一网络控制器 130可将该绝对值直 接替换更新前的接入阈值, 以得到更新后的接入阈值。 在更新值为相对值 时, 可通过如下公式获取更新后的接入阈值:
接入阈值=调整步长 * (用户等级-最低用户等级)
其中, 调整步长的取值范围为 (0, 20] , 本实施例优选默认值为 10, 单位是 db, 用户等级为发出第一信号的终端对应的用户等级, 最低用户等 级为预先设置的允许终端 330接入第一网络的最低的用户等级。
本实施例和第十一实施例由于对待接入的终端 330进行了用户等级的 划分, 限制低等级的用户等级的终端 330 的接入, 能够实现对第一网络的 网络资源进行等级优化配置, 从而确保接入的终端 330与第一网络的通信 质量, 并提升网络接入点 125的频谱效率。
本发明还提供第十三实施例的负载控制方法, 其在第一实施例所揭示 的负载控制方法的基础上进行详细描述。 在本实施例中, 网络设备基于图 2 所示实施例的网络设备 120。 如图 10所示, 本实施例所揭示的负载控制方 法包括:
步骤 S101 : 第一网络控制器 130根据已接入的终端 330的信号强度小 于或等于预设的断开阈值的终端 330形成断开终端列表, 并将断开终端列 表发送至网络接入点 125。
步骤 S102: 网络接入点 125根据断开终端列表进行断开操作。
步骤 S103: 第一网络控制器 130获取第一网络的网络接入点 125的负 载。
步骤 S104: 第一网络控制器 130根据网络接入点 125的负载配置接入 条件。
步骤 S105: 网络接入点 125从待接入的终端 330获取第一信号, 并根 据第一信号获取待接入的终端 130的信号强度。
步骤 S106: 网络接入点 125将信号强度与接入阈值进行比较。
步骤 S107: 若信号强度大于或等于接入阈值, 则网络接入点 125向待 接入的终端 330发送第二信号, 以允许终端 330接入。
在本实施例的步骤 S101中, 断开阈值优选为配置的接入阈值与预设的 固定值之差, 固定值为 10, 单位为 dbm。
本发明还提供第十四实施例的负载控制方法, 其在第十三实施例所揭 示的负载控制方法的基础上进行详细描述。 本实施例与上述第十二实施例 的不同之处在于:
在步骤 S101和 S102中, 直接由网络接入点 125比较已接入终端 330 的信号强度与断开阈值的大小, 并由网络接入点 125进行断开操作。
本实施例和第十三实施例, 在待接入的终端 330发送第一信号之前, 断开信号强度小于或等于断开阈值的已接入的终端 330与第一网络的连接, 降低了第一网络的负载, 从而能够保证新接入的终端 330与第一网络之间 的通信质量, 并提升第一网络的网络接入点 125的频谱效率。
本发明还提供一种网络设备, 其在第一实施例所揭示的网络设备 120 的基础上进行详细描述。 如图 11所示, 本实施例所揭示的网络设备 120包 括接收器 421、 处理器 422以及发送器 423。 本实施例的网络设备 120用于 与终端 330建立网络连接,终端 330包括终端接收器 531和终端发送器 532。
其中, 终端发送器 532发出请求接入的第一信号, 接收器 521获取第 一信号并获取第一网络的负载, 处理器 522根据负载配置接入条件, 以及 根据第一信号获取终端 330 的测量量, 并将测量量与接入条件进行比较, 若测量量大于或等于接入条件, 则发送器 523向终端 330发送第二信号, 终端接收器 531接收该第二信号, 并据此接入第一网络, 从而建立网络连 接。
本发明还提供一种网络设备,其在图 11所示实施例揭示的网络设备 120 的基础上进行详细描述。 在本实施例中, 如图 12所示, 网络设备 120包括 第一网络的网络接入点 125和第一网络控制器 130,第一网络控制器 130包 括第一接收器 631、 第一处理器 632以及第一发送器 633 , 网络接入点 125 包括第二接收器 626、 第二处理器 627以及第二发送器 628。
其中, 第二处理器 627根据网络接入点 125的负载配置接入阈值, 并 将终端 330的信号强度与接入阈值进行比较。
或者, 第一接收器 631获取网络接入点 125的负载, 第一处理器 632 根据网络接入点 125的负载配置接入阈值, 第一发送器 633将接入阈值发 送至第二接收器 626,第二处理器 627将终端 330的信号强度与接入阈值进 行比较。

综上所述, 本发明通过将待接入的终端 330 的测量量与根据网络接入 点 125 的负载配置的接入条件相比较, 在测量量大于或等于接入条件时允 许终端 330接入, 从而能够提升网络接入点 125的频谱效率。
以上所述仅为本发明的实施例, 并非因此限制本发明的专利范围, 凡 是利用本发明说明书及附图内容所作的等效结构或等效流程变换, 或直接 或间接运用在其他相关的技术领域, 均同理包括在本发明的专利保护范围 内。
