Description

控制接入无线局域网的方法、 装置、 设备和系统 技术领域
本发明涉及通信技术领域, 特别涉及一种控制接入无线局域网的方法、 装 置、 设备和系统。 背景技术
近年来, 智能终端和移动应用的迅速普及带来了移动互联网的快速发展, 给移动网络带来大数据量沖击,全球范围内运营商的 2G/3G移动网络频频发生 超负荷的情况。 由于目前和未来绝大多数的智能终端都支持 WLAN ( Wireless Local Area Network, 无线局域网), 在 LTE ( Long Term Evolution, 长期演进) 广泛部署以前, 原本主要用于企业和家庭场景的 WLAN被业界普遍视作一种 能够为运营商卸载移动网络数据流量的途径而广受关注。 如何将采用 WLAN 技术的网络改进为蜂窝运营商可运营或可与蜂窝运营商网络互通的网络形态, 是很多运营商希望首先解决的问题。 当前已有运营商在部署 femto cell (飞蜂 窝)、 pico cell (微微蜂窝)或 micro cell (微蜂窝)等蜂窝网络小型基站时, 同 时在基站上集成 WLAN AP ( Access Point, 接入点;), 可以解决 WLAN AP的 布放以及与蜂窝网络小型基站的传输资源的共用问题。
当 WLAN AP布放好以后, UE ( User Equipment , 用户设备 ) 可以通过内 部的 WLAN模块来扫描和接入 WLAN AP。但是, 由于有些 WLAN AP设置了 密码, 会存在大量 UE在扫描到 WLAN AP之后因不知道密码却无法接入和访 问业务的情景。 而且, UE持续不断的扫描、 尝试接入周围的 WLAN AP不仅 消耗了系统资源, 也增加了功耗, 如果 UE自动接入恶意网络, 也可能带来安 全隐患。 对于 WLAN和 3GPP ( 3rd Generation Partnership Project, 第三代合作 伙伴计划 ) RAT ( Radio Access Technology , 无线接入技术 ) 的双模或多模终 端来说, 为了省电、 安全和性能等原因, 一般情况下其 WLAN模块是关闭的。 因此,如何实现 UE对 WLAN AP有效的发现和选择,是迫切需要解决的问题。
目前, ANDSF ( Access Network Discovery Support Functions , 接入网给发 现与选择功能)可以通过核心网服务器发送信息和策略给 UE, 但是, 这种交 互增加了时延和网络负担, 效率较低。 另一方面, UE可以向 WLAN AP发送 查询请求, 但是发送请求前 UE无法确定该 WLAN AP是否可以接入, 因此, 无指导的大量终端查询将造成网络拥塞, 且 UE在何时触发利用策略和执行均 是 UE自己实现, 行为不可控。 发明内容

本发明实施例涉及 WLAN的接入,其中, WLAN AP部署在蜂窝网接入节 点上, 该部署可以为集成或者合设 ( integrated or collocated )。 本发明实施例中 的蜂窝网接入节点可以是一个单独的设备, 或者也可以包括多个设备。
例如, 蜂窝网接入节点可以是 LTE中的 eNodeB ( evolved Node Base, 演 进的基站 ),或者,蜂窝网接入节点包括 3G中的 RNC( Radio Network Controller, 无线网络控制器)与 NodeB ( Node Base, 基站), 或者, 蜂窝网接入节点包括 2G中的 BSC ( Base Station Controller, 基站控制器)与 BTS ( Base Transceiver Station, 基站收发台)。
本发明实施例涉及的第一蜂窝网接入节点是指 UE当前驻留的蜂窝网接入 节点, 该蜂窝网接入节点当前为 UE提供服务, 涉及的第二蜂窝网接入节点是 指集成或合设有 WLAN AP的蜂窝网接入节点。 所述第二蜂窝网接入节点可以 为 2G、 3G、 LTE或 CDMA ( Code Division Multiple Access,码分多址) 2000等 蜂窝网络小型基站, 如: femto cell (飞蜂窝)、 pico cell (微微蜂窝)、 micro cell (微蜂窝 )或 RRU ( Radio Remote Unit, 射频拉远单元 )等等。
参见图 1 , 为本发明实施例提供的一个网络架构示意图, 以 LTE为例进行 说明。 其中, eNB为第一蜂窝网接入节点, HeNB ( Home eNB或 Home NB , 家庭演进基站或家庭基站 )为第二蜂窝网接入节点,其上集成或合设有 WLAN ΑΡ, UE当前驻留在 eNB的覆盖范围内, 同时该 UE也落入了 WLAN AP和 HeNB的覆盖范围内, 因此, 可以通过 eNB控制 UE接入该 WLAN AP , 以实 现 UE快速、 有效的发现和接入 WLAN AP。 需要说明的是, 作为第二蜂窝网 接入节点的小型基站 (小站), 可以是图中的家庭(演进)基站 (毫微微蜂窝 基站), 也可以是微微蜂窝基站, 微蜂窝基站等。 实施例 1
参见图 2, 本实施例提供了一种控制接入无线局域网的方法, 包括:
201: 第一蜂窝网接入节点确定无线局域网接入点 WLAN AP满足用户设 备 UE接入的条件;
202:第一蜂窝网接入节点向 UE发送指示信息以指示所述 UE接入 WLAN 网络,其中,所述指示信息中包含所述 WLAN AP的标识,或者包含所述 WLAN AP的标识和至少一个其他 WLAN AP的标识, 所述至少一个其他 WLAN AP 提供的业务与所述 WLAN AP提供的业务相同。
本实施例中, 所述至少一个其他 WLAN AP提供的业务与所述 WLAN AP 提供的业务相同, 具体地, 可以是所述至少一个其他 WLAN AP对应的 SSID ( Service Set Identification,业务集标识 )与所述 WLAN AP对应的 SSID相同。
本实施例中, 进一步地该方法还可以包括:
该第一蜂窝网接入节点从该 UE获取第二蜂窝网接入节点的小区的测量报 告.
该第一蜂窝网接入节点确定该 WLAN AP满足用户设备 UE接入的条件, 包括:
该第一蜂窝网接入节点根据该第二蜂窝网接入节点的发射功率和该 WLAN AP的发射功率, 以及该测量报告中包含的信号质量, 所述信号质量为 该 UE从该第二蜂窝网接入节点接收的信号的质量, 确定该 WLAN AP满足该 UE接入的条件。
其中, 该测量报告中至少包含该第二蜂窝网接入节点的标识和 UE接收到 的该第二蜂窝网接入节点的信号质量信息。 所述信号质量信息包括但不限于: 接收信号强度 ( Received Signal Strength Indicator )或接收信号功率(Reference Signal Receiving Power )等等, 本实施例对此不做具体限定。
本实施例中, 进一步地, 该第一蜂窝网接入节点根据该第二蜂窝网接入节 点的发射功率和该 WLAN AP的发射功率, 以及该测量报告中包含的该 UE接 收的该第二蜂窝网接入节点的信号质量, 确定该 WLAN AP满足该 UE接入的 条件, 可以包括:
该第一蜂窝网接入节点根据该第二蜂窝网接入节点的发射功率和该 WLAN AP的发射功率, 以及该测量报告中包含的该 UE接收的该第二蜂窝网 接入节点的信号质量, 以及该第二蜂窝网接入节点的发射频率和该 WLAN AP 的发射频率, 确定该 WLAN AP满足该 UE接入的条件。
例如, 第二蜂窝网接入节点的发射功率为 Pc dBm, UE接收第二蜂窝网接 入节点的信号功率 Rc dBm (以接收信号功率为例, 接收信号强度与接收信号 功率有一定的换算关系), 蜂窝网接入节点基站到 UE的下行路径损耗为 PLc, 蜂窝网接入节点的发射频率为 fc; WLAN AP的发射功率为 Pw dBm, UE接收 WLAN AP的信号功率为 Rw dBm, WLAN AP到 UE的下行路径损耗为 PLw, WLAN AP的频率为 fw。 则可以采用以下方法计算出 Rw:
PLc = Pc - Rc;
PLw = Pw - Rw;
PLw = PLc - 201og10 (fc/fw);
Rw = Pw— [PC - Rc - 201og10 (fc/fw) ];
收到该测量报告的第一蜂窝网接入节点根据计算出的 Rw,可以判断出 UE 目前可能的接收 WLAN AP的信号功率能否达到预设的阀值,如果达到该阈值, 则认为 UE在当前位置适合接入该 WLAN AP, 即该 WLAN AP能满足 UE接 入的条件;如果未达到该阈值,则认为 UE在当前位置不适合接入该 WLAN AP , 即该 WLAN AP不能满足 UE接入的条件。
本实施例中, 进一步地, 该第一蜂窝网接入节点从该 UE获取该第二蜂窝 网接入节点的小区的测量报告, 可以包括:
该第一蜂窝网接入节点发送测量配置信息给该 UE, 该测量配置信息包含 该第二蜂窝网接入节点的小区的物理小区标识;
接收该 UE根据该测量配置信息对该小区进行测量后上报的该测量报告。 本实施例中, 进一步地, 该第一蜂窝网接入节点从该 UE获取该第二蜂窝 网接入节点的小区的测量报告, 可以包括:
该第一蜂窝网接入节点发送测量配置信息给该 UE, 该测量配置信息包含 测量指示信息和该第二蜂窝网接入节点的小区的物理小区标识, 该测量指示信 息用于指示该 UE读取该小区的系统消息中的小区全球标识 CGI;
接收该 UE根据该测量配置信息对该小区进行测量后上报的该测量报告, 该测量报告包含该 CGI;
根据该 CGI为该第二蜂窝网接入节点的 CGI确定所述测量报告为所述第 二蜂窝网接入节点的小区的测量报告。
所述测量指示信息指示 UE读取小区系统消息中的 CGI, 主要是出于两方 面的考虑。 首先, UE对第二蜂窝网接入节点进行测量后, 测量报告中的物理 小区标识可能会有沖突, 不同蜂窝网接入节点的物理小区标识可能会出现重 复, 网络需要根据 CGI确定 UE上报的测量报告是哪个目标蜂窝网接入节点。 其次, 不一定每个蜂窝网接入节点所在的站点都集成或合设了 WLAN AP, 网 络需要根据该 CGI找到对应的该蜂窝网接入节点的记录,查询是否该蜂窝网接 入节点集成或合设了 WLAN AP。 所述物理小区标识产生沖突的原因是, 物理小区标识是 9bit的标识, 其选 择范围有限。在使用时,特别是针对集成或合设 WLAN AP的蜂窝网接入节点, 一定区域内如源基站小区覆盖范围内也可能重复使用。 一般 UE在测量报告里 只需上报物理小区标识和接受信号质量, 这样源基站就难以判断测量报告是哪 个小区的, 因此就会产生物理小区标识的沖突。
本实施例提供的上述方法, 通过第一蜂窝网接入节点确定无线局域网接入 点 WLAN AP满足用户设备 UE接入的条件, 向所述 UE发送指示信息以指示 所述 UE接入 WLAN网络, 其中, 所述指示信息中包含所述 WLAN AP的标 识, 或者包含所述 WLAN AP的标识和至少一个其他 WLAN AP的标识, 所述 至少一个其他 WLAN AP提供的业务与所述 WLAN AP提供的业务相同, 从而 能够指导 UE快速地、 有效地发现、 选择和接入 WLAN。 网络根据自己掌握的 蜂窝和 WLAN网络信息及控制 UE做的测量, 做出 UE进入 WLAN网络覆盖 区域的判断。 避免了 UE不断自主发现的方式存在的长时间扫描、 查询 WLAN 网络等引起的 UE电量消耗过快、 无法有效发现可用 WLAN网络、 WLAN网 络空口拥塞的问题,且由 UE目前附着的蜂窝网络指导 UE的行为, UE只需遵 循指令进行网络发现, 行为可控, 效率高, UE实现筒单。 实施例 2

参见图 11 ,本实施例提供了一种控制接入无线局域网的方法, 用于第一蜂 窝网接入节点控制 UE接入 WLAN AP的场景, 其中, 以第一蜂窝网接入节点 为 eNB, 第二蜂窝网接入节点为 HeNB为例进行说明, 在蜂窝网接入节点为其 它设备时的流程与此相似, 此处不做过多说明。 所述方法包括:
1101: 源 eNB发送 RRC Reconfiguration连接重配消息给 UE, 其中携带有 测量配置信息,指示 UE进行测量,所述测量配置信息中包括目标 HeNB的 PCI, 该目标 HeNB上集成或合设有 WLAN AP。 本实施例中,以所述目标 HeNB的小区标识是目标 HeNB的 PCI为例进行 说明。 在 LTE中物理小区标识是 PCI, 在 3G中物理小区标识是 PSC ( Primary Synchronization Code, 主扰码), 此处不做过多说明。
其中, 源 eNB为当前为 UE提供服务的第一蜂窝网接入节点, 目标 HeNB 是指集成或合设有 WLAN AP的第二蜂窝网接入节点。 所述测量配置信息中可 以包括一个第二蜂窝网接入节点的小区标识, 或者也可以包括多个第二蜂窝网 接入节点的小区标识。
本实施例中, 源 eNB 已获知目标 HeNB 的信息以及其上集成或合设的 WLAN AP的信息, 包括但不限于: 目标 HeNB的标识、 覆盖范围、 发射功率、 WLAN AP的标识、 频点、 发射功率、 运行状态、 能力、 负荷、 支持的网络接 入方式、 支持的 PLMN列表等等。 其中, 源 eNB可以根据 UE当前的位置可 能在哪些集成或合设有 WLAN AP的目标 HeNB的覆盖范围下, 来决定将这些 目标 HeNB的小区标识下发给 UE , 以指示 UE对这些目标 HeNB进行测量。
1102: UE收到该 RRC连接重配置消息后, 获取其中的测量配置信息, 根 据该测量配置信息中包含的目标 HeNB的小区标识,对相应的目标 HeNB进行 测量, 并上报测量报告给源 eNB, 其中, 所述测量报告中包括测量的各个目标 HeNB的 PCI。
本实施例以物理小区标识为 PCI进行说明, 在其它应用场景下, 所述物理 小区标识也可以为 PSC。
优选地, UE也可以在接收到的信号质量达到预设的阈值时上报测量报告。 所述预设的阈值可以根据需要设定, 此处不限定。
1103: 源 eNB接收 UE上报的测量报告,根据测量报告中的 PCI判断是否 发生 PCI沖突, 如果发生 PCI沖突, 则执行步骤 1104; 如果未发生 PCI沖突, 则执行步骤 1107。
本实施例中, PCI发生沖突是指不同的蜂窝网接入节点使用了相同的 PCI, 则导致无法区分蜂窝网接入节点。
例如,第二蜂窝网接入节点的 PCI与宏蜂窝网接入节点小区的 PCI在一个 取值范围内且相同,则第一蜂窝网接入节点无法根据测量报告中的 PCI区分出 该 PCI对应的是第二蜂窝网接入节点还是宏蜂窝网接入节点。 再如, 给第二蜂 窝网接入节点单独分配特殊的 PCI取值范围, 由于第二蜂窝网接入节点的数量 较多, 不同的第二蜂窝网接入节点可能重用 PCI, 则第一蜂窝网接入节点仍无 法根据测量报告中的 PCI确定 UE测量的是哪个第二蜂窝网接入节点。
1104: 源 eNB向 UE发送 RRC连接重配置消息, 指示 UE读取所述 PCI 对应的小区的 SI ( System Information , 系统消息)。
1105: UE读取所述 PCI对应的小区的系统消息, 获取系统消息中的 CGI。 所述系统消息至少包括 CGI, 此外还可以包括以下信息中的一种或者多 种,如 TAI( Tracking Area Identity,跟踪区标识 ), CSG( Closed Subscriber Group, 闭合用户群)标识、 成员指示或集成 /合设 WLAN AP指示等等。 所述系统消息 通常由 BCCH ( (Broadcast Control Channel, 广播控制信道) 来传输。

1107: 源 eNB根据测量报告中的 PCI或 CGI找到对应的 HeNB, 根据已 获知的目标 HeNB的信息以及其上集成或合设的 WLAN AP的信息, 确认该 HeNB是集成或合设 WLAN AP的蜂窝网接入节点, 然后, 源 eNB根据测量报 告中 UE的接收信号质量,以及已获知的该目标 HeNB与集成或合设的 WLAN AP的覆盖范围的比率和 /或发射功率的比率, 计算出 UE在该 WLAN AP的覆 盖范围内的相对位置, 或者计算出 UE当前的位置对该 WLAN AP的接收信号 质量;并根据计算出的 UE在该 WLAN AP的覆盖范围内的相对位置,或者 UE 当前的位置对该 WLAN AP的接收信号质量, 确认 UE当前的位置是否适合接 入该 WLAN AP。
其中, 如果发生 PCI沖突, 则源 eNB根据收到的测量报告中的 CGI找 到对应的 HeNB; 如果未发生 PCI沖突, 则源 eNB根据收到的测量报告中的 PCI找到对应的 HeNB。
其中,如果源 eNB收到的测量报告中包含有集成 /合设 WLAN AP的指示, 则源 eNB可以直接根据该指示确认测量报告中的 CGI对应的 eNB为集成或合 设 WLAN AP的 eNB。
进一步地, 源 eNB还可以根据所述 WLAN AP的信息和所述 UE的能力, 确定 UE接入该 WLAN AP的接入方式为切换接入或并发连接接入, 并将确定 的接入方式指示给 UE。
其中,所述 WLAN AP的信息包括该 WLAN AP的标识,或者,所述 WLAN AP的信息包括该 WLAN AP的标识以及以下至少一种:
i WLAN AP的频点;
i WLAN AP的负荷;

1108:如果源 eNB确认 UE当前的位置适合接入该 WLAN AP,而该 WLAN AP还未开启,则源 eNB向该目标 HeNB发送开启指示,指示开启该 WLAN AP 使该 WLAN AP进入运行状态。
优选地, 源 eNB还可以在该开启指示中携带指定的频点和 /或指定的发射 功率, 以指示目标 HeNB将 WLAN AP的频点调整为该指定的频点, 和 /或, 将 WLAN AP的发射功率调整为该指定的发射功率。
例如, 源 eNB计算出 UE在该 WLAN AP的覆盖范围内的相对位置较远, 接近该覆盖范围的边缘, 或者计算出 UE当前的位置对该 WLAN AP的接收信 号质量较弱, 则可以通过上述方式指示 WLAN AP进行发射功率的调整, 使得 WLAN AP增强发射功率, 保证了 UE在 WLAN AP的有效覆盖范围内。
本步骤为可选的步骤, 如果该 WLAN AP已开启, 则不用执行本步骤, 直 接执行后续的步骤。
1109: 源 eNB向 UE发送包含该 WLAN AP的标识的连接指示, 指示 UE 接入到该 WLAN AP; 或者, 如果 UE未打开 WLAN模块, 则源 eNB向 UE发 送包含所述 WLAN AP的标识的连接指示,指示 UE打开 WLAN模块并接入该 WLAN AP0

所述切换接入是指 UE将全部数据流转移到 WLAN AP进行传输, 所述并 发连接接入是指 UE将部分数据流转移到 WLAN AP进行传输。 在切换接入的 场景下, 如果切换之前 UE驻留在 LTE中, 则转移所有数据流到 WLAN时, UE可以执行到 2G或 3G网络的小区重选,驻留在 2G或 3G网络的 CS域,保 证用户正常使用语音业务。在并发连接的场景下,如果 UE有 IMS( IP Multimedia Subsystem, IP多媒体系统 )业务的 PDN连接, 则 IMS业务的 PDN连接可以 不转移到 WLAN。
1111: UE接入所述 WLAN AP之后, 如果接入成功, 则发送接入成功的 通知给源 eNB;或者,如果扫描到所述 WLAN AP且判断所述 WLAN AP可用, 则发送找到所述 WLAN AP的通知给源 eNB; 或者, 如果无法接入或者经过指 定时长或指定次数接入后接入失败, 则发送接入失败的通知给源 eNB; 或者, 法找到所述 WLAN AP或所述 WLAN AP不可用的通知给源 eNB ,该通知包括 所述 WLAN AP的标识。

根据所述 CGI为所述第二蜂窝网接入节点的 CGI确定所述测量报告为所 述第二蜂窝网接入节点的小区的测量报告。
所述测量指示信息指示 UE读取小区系统消息中的 CGI, 主要是出于两方 面的考虑。 首先, UE对第二蜂窝网接入节点进行测量后, 测量报告中的物理 小区标识可能会有沖突, 不同蜂窝网接入节点的物理小区标识可能会出现重 复, 网络需要根据 CGI确定 UE上报的测量报告是哪个目标蜂窝网接入节点。 其次, 不一定每个蜂窝网接入节点所在的站点都集成或合设了 WLAN AP, 网 络需要根据该 CGI找到对应的该蜂窝网接入节点的记录,查询是否该蜂窝网接 入节点集成或合设了 WLAN AP。
所述物理小区标识产生沖突的原因是, 物理小区标识是 9bit的标识, 其选 择范围有限。在使用时,特别是针对集成或合设 WLAN AP的蜂窝网接入节点, 一定区域内如源基站小区覆盖范围内也可能重复使用。 一般 UE在测量报告里 只需上报物理小区标识和接受信号质量, 这样源基站就难以判断测量报告是哪 个小区的, 因此就会产生物理小区标识的沖突。

相应地, 接收机 2103用于:
接收所述 UE根据所述测量配置信息对所述小区进行测量后上报的所述测 量报告。
本实施例中, 发射机 2102还用于:
发送测量配置信息给所述 UE, 所述测量配置信息包含测量指示信息和所 述第二蜂窝网接入节点的小区的物理小区标识, 所述测量指示信息用于指示所 述 UE读取所述小区的系统消息中的小区全球标识 CGI; 相应地, 接收机 2103用于:

处理器 2101用于:
根据所述 CGI为所述第二蜂窝网接入节点的 CGI确定所述测量报告为所 述第二蜂窝网接入节点的小区的测量报告。
所述测量指示信息指示 UE读取小区系统消息中的 CGI, 主要是出于两方 面的考虑。 首先, UE对第二蜂窝网接入节点进行测量后, 测量报告中的物理 小区标识可能会有沖突, 不同蜂窝网接入节点的物理小区标识可能会出现重 复, 网络需要根据 CGI确定 UE上报的测量报告是哪个目标蜂窝网接入节点。 其次, 不一定每个蜂窝网接入节点所在的站点都集成或合设了 WLAN AP, 网 络需要根据该 CGI找到对应的该蜂窝网接入节点的记录,查询是否该蜂窝网接 入节点集成或合设了 WLAN AP。
所述物理小区标识产生沖突的原因是, 物理小区标识是 9bit的标识, 其选 择范围有限。在使用时,特别是针对集成或合设 WLAN AP的蜂窝网接入节点, 一定区域内如源基站小区覆盖范围内也可能重复使用。 一般 UE在测量报告里 只需上报物理小区标识和接受信号质量, 这样源基站就难以判断测量报告是哪 个小区的, 因此就会产生物理小区标识的沖突。
