本发明涉及通信技术领域,特别涉及一种 Femto小区的邻区配置 方法和设备。 背景技术
随着第三代移动通信技术( 3rd-generation, 3G ) 的发展, 3G时 代已经来临, 各种高速无线应用正在不断改变人类的生活方式。
随着无线带宽的不断提升,大众攫取信息的模式发生着根本性的 改变, 随时随地沟通正在成为可能, 3G将手持终端打造成信息交汇 的舞台。 3G通信赋予信息时代的特性就是大量数据业务的产生, 其 将互联网业务有效的延伸到移动通信领域。
随着业务不断发展和用户消费习惯的不断改善,越来越多的业务 使用发生在家庭区域, 而相当数量的业务使用发生在公司、餐馆等室 内环境。 因此, 室内无线覆盖的好坏决定了用户的业务使用感知, 而 如何有效改善 3G网络的室内覆盖, 是 3G业务是否能够成功部署的 关键。
然而, 3G网络所采用的 2.1GHz频段资源,传输损耗和空间损耗 较大, 对建筑物墙体的穿透能力十分薄弱,运营商面临的最大问题就 是室内覆盖质量往往不尽人意。
同时, 作为大量数据业务承载的区域, 如何有效的整合固定接入 和移动宽带资源是运营商在全业务运营中所面临的棘手问题。
为了克服上述问题, 现有技术中引入了 Femto (毫微微)蜂窝网 络技术。 首先, Femto增强了网络对用户的粘性。 融合式 Femto将移动、 固定、 宽带业务都融合在一起, 用户通过一个 Femto就能实现其所有 的通信需求, 并享受业务在不同接入模式中的融合漫游, 大大增加用 户粘性, 帮助运营商巩固用户规模并发展家庭用户。
其次, Femto节省了网络建设成本。 Femto借助于固定宽带接入 作为其回程, 没有站址选取和建设维护方面的投入, 大大降低运营商 在网络建设方面的投资。
此外, Femto部署也减轻了宏 (Macro )蜂窝网络的业务负荷。 同时, Femto还可以实现平滑演进,由于 Femto采用扁平化架构, 符合移动网络演进的趋势如 LTE( Long Time Evolved,长期演进)/EPS ( Evolved Packet System, 演进分组系统;); 扁平化架构由于减少了节 点数, 也更符合全 IP ( Internet Protocol, 网络互联协议 ) 网络中实时 业务对时延的严格要求。
对于 Femto的邻区配置方案,现有方案中需要将周围所有邻区配 置到本小区的邻区列表中。但是, 通常每个家庭基站对其准入用户有 明确的限制。对于在其准入列表中的用户允许接入, 或由其他小区切 换到本小区; 反之, 对于不在其准入列表中的用户不允许其接入或切 换至本小区。
现有方案中对所有邻区测量导频信道接收功率,并上报 Femto网 关, 当满足切换条件时,将目标基站标识和用户标识发送给 Femto准 入鉴权设备进行查询, Femto网关根据返回的判决结果进行准入控制。
当处于 Idel (空闲 )状态的终端设备满足小区重选条件时, 会重 选至目标小区, 在发起位置区更新或发起业务判断其准入条件, 对于 不在小区准入列表中的终端设备拒绝接入。
在实现本发明实施例的过程中,申请人发现现有技术至少存在以 下问题:
当用户不在目标小区的准入列表中时,上述测量判断操作都是没 有意义的, 从而, 对终端设备的测量上报开销和网关的切换、 重选条 件判断、 准入判断等都存在较大的浪费。 发明内容

通知模块, 用于向所述 Femto小区所对应的基站发送通知消息, 所述通知消息中携带当前所述确定模块所确定的所述 Femto 小区的 全部邻区的信息。
与现有技术相比, 本发明实施例具有以下优点:
通过应用本发明实施例的技术方案, 在邻区列表维护过程中, 参 考邻小区准入模式, 去除不必要的邻区配置, 节省了终端的测量上报 开销,从而, 可以避免将 Femto小区所有周围邻区配置在邻区列表中 所导致的系统资源浪费的问题, 筒化了切换、 小区重选判断的过程。 附图说明
图 1为本发明实施例提出的一种 Femto小区的邻区配置方法的流 程示意图;
图 2 为本发明实施例提出的一种具体应用场景下的网络结构示 意图;
图 3为本发明实施例提出的一种具体应用场景的示意图; 图 4为本发明实施例提出的一种网络设备的结构示意图。 具体实施方式
如背景技术所述, 为了避免现有技术中的存在的大量不必要的邻 区配置,本发明实施例所提出的技术方案主要思想是在邻区关系建立 P介段, 依据候选邻区的准入方式, 对其进行筛选。
如果候选邻区是封闭式的准入模式, 则进一步根据该候选邻区与 当前小区的准入列表中是否包含相同的用户,来确定是否将该候选邻 区配置成邻区; 如果候选邻区是开放式或混合式的准入模式, 则将其 配置成邻区。
如图 1所示, 为本发明实施例提出的一种 Femto小区的邻区配置 方法的流程示意图, 该方法具体包括以下步骤:
步骤 S101、接收 Femto小区所对应的基站上报的当前检测到的各 候选邻区的信息。 其中, Femto小区所对应的基站即为家庭基站, 其将该 Femto小 区周围所有可能成为邻区的候选邻区的相关信息均进行上报。
在实际的应用中, 家庭基站的上报对象可以为 Femto网关, 即本 发明实施例中各步骤的执行主体可以为 Femto网关, 当然, 也可以根 据实际需要通过其他网络设备执行相应的操作流程,这样的执行主体 的变化, 并不会影响本发明的保护范围。
步骤 S102、 识别各候选邻区的准入模式。
在实际应用中, 具体的识别过程需要 Femto准入鉴权设备来进行 辅助, 相应的处理过程如下:
首先, 根据接收到的各候选邻区的信息, 向 Femto准入鉴权设备 发送准入模式查询请求。
然后, 接收 Femto准入鉴权设备返回的各候选邻区的准入模式信 当根据接收到的查询结果, 确定一个候选邻区的准入模式为开放 模式或混合模式时, 则执行步骤 S103。
而当根据接收到的查询结果, 确定一个候选邻区的准入模式为封 闭模式时, 本方法还包括以下的进一步查询处理流程:
向 Femto准入鉴权设备发送 Femto小区和该封闭模式的候选邻区 的准入列表查询请求;
根据 Femto准入鉴权设备返回的准入列表, 判断 Femto Ί、区和该 封闭模式的候选邻区的准入列表中是否存在相同的用户。
当 Femto小区和该候选邻区的准入列表存在相同的用户时, 执行 步骤 S103;
当 Femto小区和该候选邻区的准入列表不存在相同的用户时, 执 行步骤 S104。 步骤 S103、 确定该候选邻区为 Femto小区的邻区。
步骤 S104、 放弃确定该候选邻区为 Femto小区的邻区。
在对所有的候选邻区均完成上述的步骤 S102至 S104的处理流程 后, 进一步执行步骤 S105。
步骤 S105、 向 Femto小区所对应的基站发送通知消息, 通知消息 中携带当前确定的 Femto小区的全部邻区的信息。
进一步的, 在本步骤完成之后, 如果 Femto小区发生了准入模式 的变化时,除了重新根据相应的 Femto小区所对应的基站上报的候选 邻区的信息进行自身的邻区配置夕卜,还包括以下的针对 Femto小区的 各候选邻区的辅助调整流程:
情况一、 当该 Femto小区的准入模式由封闭模式变更为开放模式 或混合模式时, 本发明实施例所提出的方法还包括以下处理流程: 接收 Femto小区所对应的基站重新上报的当前检测到的所有候选 邻区的信息;
通知所有候选邻区将该 Femto小区配置为邻区。
情况二、 当该 Femto小区的准入模式由开放模式或混合模式变更 为封闭模式时, 本发明实施例所提出的方法还包括以下处理流程: 接收该 Femto小区所对应的基站重新上报的当前检测到的所有候 选邻区的信息;
判断该 Femto 小区和各候选邻区的准入列表是否存在相同的用 户;
如果判断结果为存在, 则应该使各候选邻区将其配置为邻区, 但 是,由于该 Femto小区原有的准入模式为开放模式或混合模式,所以, 所有将其作为候选邻区的小区均已将其配置为邻区, 因此, 无需再进 行调整,但如果判断结果为不存在,且该 Femto小区已被配置为其他 候选邻区的邻区,则通知相应的候选邻区放弃将该 Femto小区配置为 自身的邻区。
当然, 在实际的应用中, 也可以不进行该 Femto小区是否已被配 置为其他候选邻区的邻区的判断,而是向所有与该 Femto小区的准入 列表不存在相同用户的候选邻区均发送通知,通知这些候选邻区不要 将该 Femto小区配置为自身的邻区,这样的变化同样属于本发明的保 护范围。
情况三、 当该 Femto小区所对应的基站关机或频点发生变更时, 本发明实施例所提出的方法还包括以下处理流程:
直接通知所有将该 Femto小区配置为邻区的各邻区所对应的基站 放弃将该 Femto小区配置为自身的邻区。
在上述的三种情况中, 对于放弃将该 Femto小区配置为自身的邻 区的具体处理过程,可以为将该 Femto小区的信息从邻区列表中直接 删除。
与现有技术相比, 本发明实施例具有以下优点:
通过应用本发明实施例的技术方案, 在邻区列表维护过程中, 参 考邻小区准入模式, 去除不必要的邻区配置, 节省了终端的测量上报 开销,从而, 可以避免将 Femto小区所有周围邻区配置在邻区列表中 所导致的系统资源浪费的问题, 筒化了切换、 小区重选判断的过程。 下面, 结合具体的应用场景, 对本发明实施例所提出的技术方案 进行说明。
对于本发明实施例所提出的技术方案, 具体的网络系统的结构示 意图如图 2所示, 其中的 TD Femto网关即可以为前述步骤 S101至 S105的处理过程的执行主体, 而 TD Femto基站, 即为前述的 Femto 小区所对应的基站。 进一步的, 基于如图 3所示的应用场景, 对 Femto小区初始邻区 配置的过程说明如下:
首先, 设备 1 (可以是 HNB, 即前述的 Femto小区所对应的基站 ) 通过测量和读邻区广播得到周围所有候选邻区的 ID, 所谓候选邻区 可以是在物理位置上与该 Femto小区相邻的可能成为其邻区的小区, 也可以是在逻辑部署或信号强度上与该 Femto 小区相邻的可能成为 其邻区的小区。
这个过程与现有技术方案一致, 在此不再重复说明。
然后,设备 1将候选邻区的列表上报至设备 2(可以是前述的 Femto 网关), 设备 2在设备 3 (可以是前述的 Femto准入鉴权设备 )辅助 下对候选邻区进行筛选,根据筛选结果,将相应的邻区配置给该 Femto 小区。
在上述的筛选过程中, 具体的筛选原则包括:
为了方便说明, 假设小区 A为初始建立的 Femto小区, 作为以下 筛选的主体, 小区 B为小区 A的基站检测到的候选邻区。
当小区 B为开放模式或混合模式时,则将其配置为小区 A的邻区。 当小区 B为封闭模式时, 对进行以下的进一步判断:
如果小区 A的准入用户也存在小区 B的准入列表中, 则将小区 B 配置为小区 A的邻区。
如果小区 A所有的准入用户均不在小区 B的准入列表中, 则不将 小区 B配置为小区 A的邻区。
同时, 以相同原则, 以小区 B为筛选主体, 更新小区 B的邻区列 表。
在上述的处理完成后, 设备 2将筛选后的邻区列表通知设备 1。 至此, 设备 1中存储了完整的邻区列表。 进一步的, 在 Femto小区的准入方式发生更新时, 对相应的邻区 更新过程说明如下:
在具体的应用场景中, 可以分为以下 3种情况:
情况一、 小区 A由封闭模式改为开放模式或混合模式:
小区 A 的基站 (设备 1 ) 重新测量周围所有候选邻区并上报至
Femto网关(设备 2 );
Femto网关通知小区 A所有候选邻区的基站,增加小区 A为邻区。 情况二、 小区 A由开放模式或混合模式改为封闭模式:
小区 A的基站将当前自身所配置的所有邻区上报给 Femto网关; Femto网关通过 Femto准入鉴权设备(设备 3 )对其进行以下判断: 如果小区 A的准入列表中的用户也存在于小区 B的准入列表中, 则应该将小区 A配置为小区 B的邻区, 但是, 由于小区 A原有的准 入模式为开放模式或混合模式, 所以, 小区 B必然已将小区 A配置 为自身的邻区, 因此, 无需再进行调整。
如果小区 A所有准入用户均不在小区 B的准入列表中, 则 Femto 网关通知小区 B的基站, 将小区 A从小区 B的邻区列表中去除。
情况三、 处于封闭模式下的小区 A的准入列表更新:
与 Femto小区初始邻区配置过程一致, 需要小区 A的基站测量并 上报所有候选邻区, Femto网关在 Femto准入鉴权设备的辅助下, 更 新小区 A及其邻区的邻区列表。
进一步的, 当小区 A的基站关机或频点变更时, 小区 A当前各邻 区的更新过程如下:
当小区 A的基站关机时, Femto网关应通知小区 A的所有邻区, 将小区 A从其各自的邻区列表中去除。
当小区 A的基站频点变更时, Femto网关应通知小区 A的所有邻 区,将小区 Α从其各自的邻区列表中去除,并且在新的频点完成 Femto 小区邻区初始配置过程。
而如果通过周期性测量的方式更新邻区, 那么, 当 Femto小区的 基站测量到新增或减少邻区时, 相应的邻区更新过程如下:
当 Femto小区的基站测量到新增邻区时,相应的处理过程与 Femto 小区初始邻区配置过程相一致, 在此不再重复说明。
而当 Femto小区的基站测量到邻区减少时, 则直接从其邻区列表 中删除该邻区。
与现有技术相比, 本发明实施例具有以下优点:
通过应用本发明实施例的技术方案, 在邻区列表维护过程中, 参 考邻小区准入模式, 去除不必要的邻区配置, 节省了终端的测量上报 开销,从而, 可以避免将 Femto小区所有周围邻区配置在邻区列表中 所导致的系统资源浪费的问题, 筒化了切换、 小区重选判断的过程。 为了实现本发明实施例的技术方案, 本发明实施例还提供了一种 网络设备, 其结构示意图如图 4所示, 具体包括:
