为了增强网络的覆盖和性能, 不同类型或不同制式的基站(例如低发射 功率基站或者发射 /接收节点)被部署在同构网络 ( Homogeneous Network ) 内。 这样的网络结构被称为异构网络( Heterogeneous Network )。 低发射功率 基站(Lower Power Node, LPN ) 可以包括微基站( Micro Base Station ), 微 微基站 (Pico Base Station ), 家庭基站(Femto Base Station )等。 异构网络 中的大发射功率基站(例如宏基站, Macro eNodeB, MeNB ) 的小区的覆盖 范围往往大于 LPN的小区的覆盖范围。 因此 MeNB的小区可以称为宏蜂窝 ( Macro Cell ), LPN的小区可以称为小蜂窝 ( Small Cell )。 MeNB可以称为 主节点, LPN可以称为从节点。
宏蜂窝的覆盖范围内可以有多个小蜂窝。每一个小蜂窝都有对应的 LPN 以及相应的处理实体。 LPN维护一个封闭用户组( Close Subscriber Group, CSG )列表。 一般情况下, 该 LPN仅为该 CGS列表中的用户设备提供服务。 但是, 在混合接入模式(Hybrid Access Mode, HAM ) 中, 该 LPN也可以为 不属于该 CGS列表的用户设备提供服务。
现有技术中,不属于 LPN的 CGS列表的用户设备在需要接入该 LPN时 会发送请求消息。核心网设备会根据该 LPN的负载情况评估是否允许该 LPN 为该用户设备提供服务。 上述过程需要涉及基站间、 基站与核心网之间的信 令交互。 大量的信令交互导致网络性能的下降。 发明内容

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行 清楚、 完整地描述, 显然, 所述的实施例是本发明的一部分实施例, 而不是 全部实施例。 基于本发明中的实施例, 本领域普通技术人员在没有做出创造 性劳动的前提下所获得的所有其他实施例, 都应属于本发明保护的范围。
应理解, 本发明实施例的技术方案可以应用于各种通信系统, 例如: 全 球移动通讯 ( Global System of Mobile communication, 简称 "GSM" ) 系统、 码分多址(Code Division Multiple Access, 简称 "CDMA" ) 系统、 宽带码分 多址( Wideband Code Division Multiple Access, 简称 "WCDMA" )系统、 通 用分组无线业务(General Packet Radio Service, 简称 "GPRS" )、 长期演进 ( Long Term Evolution,简称 "LTE" )系统、 LTE频分双工( Frequency Division Duplex, 简称 "FDD" ) 系统、 LTE时分双工 ( Time Division Duplex, 简称 "TDD" )、 通用移动通信系统 ( Universal Mobile Telecommunication System, 简称 "UMTS" )等。

图 1是根据本发明实施例提供的控制用户设备接入的方法的示意性流程 图。 图 1所示的方法由异构网络中的 LPN基站执行。
101, 确定该 LPN的无线资源使用情况。
102,根据该 LPN的无线资源的使用情况,为待接入用户设备提供服务。 根据图 1所示的方法, LPN可以主动发起用户设备的切换, 将由其他基 站提供服务的用户设备切换到该 LPN上。 在重载的异构网络中, 图 1所示 的方法能够快速灵活的对用户设备进行切换, 有效地平衡宏基站和 LPN 的 负载。 此外, 由于不需要用户设备通过信令触发基站的切换, 图 1所示的方 法能够节约信令开销并且能够有效避免用户设备穷举搜索所有相邻小区以 寻找空闲资源的行为。
该 LPN可以从符合第一条件的用户设备中选择出该待接入用户设备。 符合第一条件的用户设备不属于该 LPN的 CSG列表,但能够接入该 LPN(即 在该 LPN的覆盖范围之内)。该 LPN可以在有空闲的无线资源的情况下, 为 该待接入用户设备提供服务。 该 LPN 可以维护临时等待列表(Temporary Waiting List, TWL ),该 TWL用于保存该符合第一条件的用户设备。该 LPN 维护的 TWL中可以是所有符合第一条件的用户设备, 也可以是部分符合第 一条件的用户设备。 在此情况下, 根据该 LPN的无线资源的使用情况, 为 待接入用户设备提供服务, 包括: 在该 LPN具有空闲无线资源的情况下, 从属于 TWL的用户设备中确定该待接入用户设备, 其中该 TWL中的用户 设备不属于该 LPN的封闭用户组 CSG列表, 但是该 TWL中的用户设备能 够接入该 LPN (即该 TWL中的用户设备在该 LPN的覆盖范围内); 为该待 接入用户设备提供服务。 该 LPN可以维护允许列表(Allowed List, AL )。 该 AL就是该 LPN当前服务的用户列表。 由该 LPN提供服务的用户设备都 属于该 AL。 也就是说, 该 LPN在为用户设备提供服务时, 需要将该用户设 备添加到该 AL中。 在此情况下, 该为该待接入用户设备提供服务包括: 将 该待接入用户设备添加到允许列表( Allowed List, AL ) 中并为该待接入用 户设备提供服务。 进一步, 在将该待接入用户设备添加到该 AL后, 该 LPN 可以将该待接入用户设备从该 TWL中删除。
进一步, 在该 LPN具有空闲无线资源的情况下, 从属于该 TWL的用户 设备中确定该待接入用户设备, 包括: 在该 LPN具有空闲无线资源的情况 下, 根据预设接入标准从属于该 TWL的用户设备中确定该接入用户设备。 可以理解的是该待用户设备需要占用的无线资源不大于该 LPN的空闲无线 资源。
该预设接入标准可以是一种预设的准则, 例如比例公平原则、 最大速率 准则、 用户设备的服务等级原则等。 换句话说, 可以根据比例公平原则从属 于该 TWL的用户设备中确定该接入用户设备, 或者, 可以根据最大速率准 则从属于该 TWL的用户设备中确定该接入用户设备, 或者, 还可以根据属 于该 TWL的用户设备的服务等级原则确定该接入用户设备。 该 TWL中的 用户设备的服务等级原则可以是根据不同参数或者指标确定的, 例如, 用户 设备的服务等级可以是根据所需无线资源的多少、用户设备的等待时间或者 延时需求, 甚至是付费情况等确定的。 这样, 一旦该 LPN具有空闲无线资 源, 该 TWL 中服务等级高的用户设备就可以被添加到 AL 中并接入到该 该待接入用户设备还可以是请求接入该 LPN的属于该 LPN的 CSG列表 的用户设备。 在此情况下, 该根据 LPN 的无线资源使用情况, 为待接入用 户设备提供服务, 包括: 在确定该 LPN没有足够的无线资源为该待接入用 户设备提供服务的情况下, 从由该 LPN提供服务的用户设备中确定移除用 户设备, 其中该移除用户设备为不属于该 LPN的 CSG列表的用户设备; 停 止为该移除用户设备提供服务; 为该待接入用户设备提供服务。 该 LPN可 以维护允许列表(Allowed List, AL )。 由该 LPN提供服务的用户设备都属 于该 AL。 也就是说, 该 LPN在为用户设备提供服务时, 需要将该用户设备 添加到该 AL中。该 LPN在停止为用户设备提供服务时, 需要将该用户设备 从该 AL中删除。在此情况下,该从由该 LPN提供服务的用户设备中确定移 除用户设备, 包括: 从 AL中确定该移除用户设备, 其中该 AL中的用户设 备由该 LPN提供服务。 该停止为该移除用户设备提供服务, 包括: 将该移 除用户设备从该 AL中删除。 该为该待接入用户设备提供服务, 包括: 将该 待接入用户设备添加到该 AL中并为该待接入用户设备提供服务。 进一步, 在将该移除用户设备从该 AL中删除后,该 LPN可以将该移除用户设备添加 到该 LPN的 TWL中。
进一步, 在确定该 LPN没有足够的无线资源为该待接入用户设备提供 服务的情况下, 从 AL中确定移除用户设备, 包括: 在确定该 LPN没有足够 的无线资源为该待接入用户设备提供服务的情况下,根据预设移除标准从该 AL中的不属于该 CSG列表的用户设备中确定该移除用户设备。可以理解该 移除用户设备移除后的可用无线资源不小于该待接入用户设备所占用的无 线资源。
该预设移除标准可以是一种预设的准则, 例如比例公平原则、 最大速率 准则、 用户设备的服务等级原则等。 换句话说, 可以根据比例公平原则, 从 该 AL中的不属于 CSG列表的用户设备中确定该移除用户设备,或者,可以 根据最大速率准测,从该 AL中的不属于 CSG列表的用户设备中确定该移除 用户设备,或者,根据该 AL中的不属于该 CSG列表的用户设备的服务等级 原则选择该移除用户设备。用户设备的服务等级可以是根据不同参数或者指 标确定的, 例如, 用户设备的服务等级可以是根据所需无线资源的多少、 用 户设备的等待时间或者延时需求甚至付费情况等确定的。 这样, 一旦有属于 CSG列表的用户设备请求接入该 LPN且该 LPN中没有足够可用的无线资源 时, AL中的不属于 CSG列表的用户设备可以按照服务等级从该 AL列表中 移除。 这样, 该 LPN就可以有足够空余的无线资源使得请求接入该 LPN的 属于 CSG列表的用户设备可以接入到该 LPN。
该 TWL中保存的是用户设备标识符(Identifier, ID )。 TWL中保存的
ID可以称为 TWL ID。也就是说,在将一个用户设备添加进 TWL时,该 LPN 将该用户设备的 TWL ID添加进该 TWL。在将该 TWL中的用户设备删除时, 该 LPN将需要删除的用户设备对应的 TWL ID从该 TWL中删除。 每一个 TWL ID都对应一个用户设备。 用户设备的 TWL ID可以是在该用户设备进 入该 TWL时分配的并在将用户设备从该 TWL中删除时从该 TWL中删除。 用户设备的 TWL ID也可以是该用户设备自身的标识符。
进一步, 该 LPN还可以接收该异构网络中的 MeNB发送的推送消息, 其中该推送消息包括推送用户设备的标识符(Identifier, ID ), 该推送用户设 备不属于该 TWL和该 LPN的 CSG列表,且该推送用户设备能够接入该 LPN, 将该推送用户设备添加到该 TWL。 进一步, 该 LPN在接收该 MeNB发送的 推送消息之前, 确定可以接受该 MeNB发送的用户设备。也就是说, 该 LPN 需要与该 MeNB进行协商来确定是否可以允许该 MeNB将用户设备推送到 该 LPN的 TWL中。
进一步,该 LPN还可以从属于该 TWL的用户设备中确定卸载用户设备, 向该异构网络中的 MeNB发送卸载消息,其中该卸载消息包括该卸载用户设 备的标识符(Identifier, ID ), 将该卸载用户设备从该 TWL中删除。 该 LPN 可以直接确定该卸载用户设备, 例如, 该 LPN可以根据属于该 TWL的用户 设备的服务等级, 确定该卸载用户设备。 该 LPN也可以根据 MeNB的指示 确定该卸载用户设备。换句话说,该卸载用户设备是由该 MeNB确定并指示 该 LPN的。
进一步, 该 LPN还可以根据清除原则, 从该 TWL中删除用户设备。 例 如, 该 LPN可以统计 TWL中的用户设备的驻留时间, 将驻留时间超过预设 时间的用户设备从该 TWL中删除。 该 LPN还可以统计 TWL中的用户设备 的吞吐量需求, 将所需吞吐量大于最大预设额度的用户设备从该 TWL中删 除, 或者, 将所需吞吐量小于最小预设额度的用户设备从该 TWL中删除。 该清除原则还可以是其他原则, 例如公平性原则, 延时需求原则, 用户设备 的服务等级原则等。
进一步, 在步骤 101之前, 该方法还可以包括: 接收属于该 TWL的用 户设备发送的切换请求。 在此情况下, 确定该 LPN 的无线资源使用情况, 包括: 在接收到属于该 TWL的用户设备发送的切换请求的情况下, 确定该 LPN的无线资源使用情况。换句话说,图 1所示方法可以由用户设备触发的。 进一步,在该 LPN接收到不属于该 TWL的用户设备发送的切换请求的情况 下, 该 LPN可以将该用户设备添加到该 TWL中。
图 2是根据本发明实施例提供的控制用户设备接入的方法的示意性流程 图。 图 2所示的方法可以由异构网络中的宏基站执行。
201 , 确定目标 LPN。
202,对该目标 LPN的 TWL进行添加用户设备操作,或,对该目标 LPN 的 TWL进行删除用户设备操作, 其中, 该 TWL中的用户设备不属于该目 标 LPN的 CSG列表但是能够接入该 LPN。
根据图 2所示的方法, MeNB能够对服务范围内的 LPN所维护的 TWL 中的用户设备进行控制。 这样, MeNB 可以合理地对整个 HetNet中的所有 LPN所维护的 TWL进行控制。 该对该目标 LPN的 TWL进行添加用户设备操作, 包括: 从主接入列表 ( Master Access List, MAL ) 中确定推送用户设备, 其中该推送用户设备能 够接入该目标 LPN; 向该目标 LPN发送推送消息, 其中该推送消息包括该 推送用户设备的 ID。
进一步, 在对该目标 LPN的 TWL进行添加用户设备操作之前, 该方法 还可以包括: 确定该目标 LPN允许添加该用户设备操作。 具体地, 该 MeNB 可以与该目标 LPN进行协商, 确定是否允许该 MeNB推送用户设备。 例如, 该 MeNB可以与该目标 LPN进行信令交换确定是否允许推送用户设备发送 给该目标 LPN。
该对该目标 LPN的 TWL进行删除用户设备操作, 包括: 接收该目标
LPN发送的卸载消息, 其中该卸载消息包括卸载用户设备的 ID; 将该卸载 用户设备添加到 MAL中。
下面将结合具体实施例对本发明进行描述。 需要说明的是, 该具体实施 例仅是为了帮助本领域技术人员更好的理解本发明而提供的例子, 并非对本 发明的限制。
图 3是根据本发明的具体实施例的示意图。
在 MeNB的覆盖范围内存在多个 LPN。第一 LPN是该多个 LPN中的任 一个 LPN。第一 LPN在同一时刻仅可以为三个用户设备提供服务。第一 LPN 维护一个 CSG列表, 该 CSG列表中有三个用户设备。 这三个用户设备分别 为用户设备 01、用户设备 02和用户设备 03,其中用户设备 01的 ID为 0001, 用户设备 02的 ID为 0002, 用户设备 03的 ID为 0003。 该 CSG列表如图 3 中的表 1所示。 该第一 LPN还维护一个 TWL和一个 AL。 由该第一 LPN提 供服务的用户设备保存在该 AL中。该 AL中可以保存的是由该第一 LPN提 供服务的用户设备的 ID。在该第一 LPN存在空闲资源的情况下,该第一 LPN 可以允许该 TWL中的用户设备接入该第一 LPN,其中该 TWL保存的是 TWL ID, TWL ID可以是 TWL保存的用户设备的 ID。
在第一时刻, 该第一 LPN的维护的 TWL中包括三个用户设备。 这三个 用户设备的 ID分别为 0011、 0012和 0013, 其中, 0011对应于用户设备 11, 0012对应于用户设备 12, 0013对应于用户设备 13。 第一时刻的 TWL如图 3中的表 2所示。 图 3中的表 3是第一时刻的该第一 LPN的 AL列表。 从表 3中可以看出, 该 AL列表中仅有一个用户设备, 该用户设备的 ID为 0011。 也就是说, 在第一时刻, 该第一 LPN仅为用户设备 11提供服务。
在第一时刻仅有一个用户设备接入该第一 LPN。 由于该第一 LPN能够 为三个用户设备提供服务且没有 CSG列表中的用户设备请求接入该 LPN, 则该第一 LPN可以从维护的 TWL中选择两个用户设备添加到 AL中。这样, 该第一 LPN可以为三个用户设备提供服务。假设 TWL的三个用户设备中服 务等级最高的用户设备为用户设备 11,服务等级最低的用户设备为用户设备 13 , 那么该第一 LPN可以将服务等级最高的两个用户设备添加到该 AL中。 在将等级最高的两个用户设备(即用户设备 11和用户设备 12 )添加到该 AL 后,该 LPN可以将 TWL中的用户设备 11和用户设备 12删除。在第二时刻, 该 TWL中仅有用户设备 13。 AL中有用户设备 01、用户设备 11和用户设备 12。第二时刻的 TWL如图 3中的表 4所示,第二时刻的 AL如图 3中的表 5 所示。
在 AL中保存的用户设备包括用户设备 01、 用户设备 11和用户设备 12 的情况下, 用户设备 02请求接入该 LPN。 由于该第一 LPN仅能够为三个用 户设备提供服务, 则该第一 LPN需要将一个用户设备从 AL中移除。 由于该 AL中的用户设备 01同时属于该 CSG列表, 因此该第一 LPN需要从不属于 CSG列表的用户设备(即 ID为 0011和 0012的用户设备) 中选择一个移除 用户设备,将该移除用户设备从该 AL中移除。该第一 LPN选择用户设备的 方法可以是随机选取, 也可以是根据用户设备的服务等级。 如果该第一 LPN 选择移除用户设备的方法是根据用户设备的服务等级, 则该 LPN可以将用 户设备 12从 AL中移除。在此之后,该第一 LPN可以将用户设备 02添加进 该 AL中。 在第三时刻, 该第一 LPN为用户设备 01、 用户设备 02和用户设 备 11提供服务。 也就是说, AL中的用户设备包括用户设备 01、 用户设备 02和用户设备 11。该第一 LPN还可以将移除用户设备拉回该 TWL。在此情 况下,该 TWL中的用户设备为用户设备 12和用户设备 13。第三时刻的 TWL 如图 3中的表 6所示, 第三时刻的 AL如图 3中的表 7所示。
图 3中的表 8是该第一 LPN所属的 HetNet中的 MeNB维护的一个 MAL。 该 MAL中包括的用户设备可以有用户设备 21、 用户设备 22、 用户设备 23。 该 MAL中可以保存用户设备的 ID, 其中用户设备 21的 ID为 0021, 用户 设备 22的 ID为 0022, 用户设备 23的 ID为 0023。 MeNB还可以将该 MAL 中的用户设备推送到该第一 LPN的 TWL中。假设这个推送过程是在第三时 刻之后的第四时刻。 MeNB选择推送用户设备时可以从 MAL中的用户设备 中任选用户设备, 也可以根据 MAL 中的用户设备的服务等级选择。 假设 MeNB 所选择的推送用户设备为用户设备 21 且该第一 LPN 可以接收该 MeNB推送的用户设备, 则第四时刻时, 该 TWL中的用户设备为用户设备 12、 用户设备 13和用户设备 21, MAL中的用户设备为用户设备 22和用户 设备 23 ο 第四时刻的 TWL如图 3中的表 9所示, 第四时刻的 MAL如图 3 中的表 10所示。
第四时刻之后,该第一 LPN还可以将 TWL中的用户设备推回该 MeNB。 该第一 LPN选择需要退回该 MAL的卸载用户设备的方法可以是根据用户设 备的服务等级。 该第一 LPN选择服务等级最低的 N个用户设备或者选择服 务等级低于预设等级的用户设备作为该卸载用户设备。 例如该第一 LPN可 以选择 TWL中服务等级最低的 1个用户设备作为卸载用户设备。 假设此时 TWL中服务等级最低的用户设备为用户设备 13,则该第一 LPN可以将用户 设备 13卸载并将用户设备 13的 ID从 TWL中删除。 该 MeNB可以将用户 设备 13添加到 MAL中。 在第五时刻, 该 TWL包括用户设备 12和用户设 备 21, 该 MAL包括用户设备 22、 用户设备 23和用户设备 13。 第五时刻的 TWL如图 3中的表 11所示, 第五时刻的 MAL如图 3中的表 12所示。
图 4是根据本发明实施例提供的基站的结构框图。 图 4所示的基站是 HetNet中的 LPN。 图 4所示的基站能够执行图 1和图 3中 LPN执行的各个 步骤。 如图 4所示, 基站 400包括第一控制单元 401和第二控制单元 402。
第一控制单元 401, 用于确定基站 400的无线资源使用情况。
第二控制单元 402, 用于根据第一控制单元 401确定的基站 400的无线 资源的使用情况, 为待接入用户设备提供服务。
图 4所示的基站 400可以主动发起用户设备的切换,将由其他基站提供 服务的用户设备切换到基站 400上。 在重载的异构网络中, 图 4所示的基站 400能够快速灵活的对用户设备进行切换,有效地平衡宏基站和 LPN的负载。 此外, 由于不需要用户设备通过信令触发基站的切换, 图 4所示的基站 400 能够节约信令开销并且能够有效避免用户设备穷举搜索所有相邻小区以寻 找空闲资源的行为。
