  • the small cell with independent attributes Only the small cell with independent attributes has the complete function of one cell in the existing system, and supports the access and residency of the user equipment in the small cell.
  • the user equipment needs to go through the handover process when moving from the Macro base station to the small cell coverage.

Description

一种连接处理和判断属性的方法、 系统及设备 本申请要求在 2012年 11月 9日提交中国专利局、 申请号为 201210449323.X、发明名称 为"一种连接处理和判断属性的方法、 系统及设备"的中国专利申请的优先权, 其全部内容 通过引用结合在本申请中。 技术领域
本发明涉及无线通信技术领域, 特别涉及一种连接处理和判断属性的方法、 系统及设 备。 背景技术
随着技术的演进和数据业务的增加, 小小区 (small cell)的概念提出并受到高度关注。 small cell通常具有较小的覆盖范围和较低的发射功率,通过将 small cell部署在距离用户更 近的位置, 例如室内和热点区域, 可以提升用户的数据速率。
根据目前的研究, small cell的类型主要分为三种, 仅具有独立属性的 small cell, 仅具 有非独立属性的 small cell和具有独立和非独立双重属性的 small cell, 图 1A和图 1B分别 给出了 small cell非独立和独立工作的示意 。
包含本地演进基站( Local e B )和宏演进基站( Macro e B ) 的异构网络部署场景如 图 1C所示。 其中 Macro基站提供宏覆盖, Local eNB在宏覆盖范围内提供热点覆盖。 图 1C 异构网络部署场景对于上图所示的网络架构, 如果按照现有机制, 用户设备 ( UE )在 Macro cell覆盖范围内移动时, 可能不断执行 Macro cell 与 Local cell之间的切换操作。 为 了避免频繁切换导致数据传输中断,一种方式就是让 UE可以同时聚合 Local eNB和 Macro eNB的资源, 但是 RRC连接维持在 Macro eNB下, Local资源仅用于数据传输, 即控制面 用户面分离技术, 也称为承载分离。
仅具有独立属性的 small cell具有现有系统中一个小区的完整功能, 支持用户设备在 small cell中接入和驻留, 用户设备从 Macro基站移动到 small cell覆盖中需要经过切换过 程。仅具有非独立属性的 small cell不具备现有系统中完整的小区功能, 不支持用户设备的 接入和驻留。 例如, 移动至非独立 small cell覆盖范围内的用户设备, 并不经过现有的切换 过程, 而是将其控制面连接(系统广播、 无线资源控制 (Radio Resource Control, RRC )信 令等)仍然保持在 Macro基站处,仅数据面连接 (上下行业务数据、调度信令等)切换至 small cell, 即承载分离。 因此, 对于仅具有非独立属性的 small cell, 需要有确定的 Macro对其 进行管理和配置。 双重属性的 small cell既能够支持独立工作的小区所应具有的所有功能, 包括允许用户设备驻留、 为用户设备提供完整的控制面和用户面连接; 同时也应具有不支 持独立工作的小区应具有的功能, 包括仅为用户设备提供用户面连接、 接受 Macro基站的 配置和管理等。 该类小区对其服务的不同用户设备表现为不同的形式, 对于驻留其中的用 户设备表现为 "独立" 形式, 对于驻留 Macro的用户设备表现为 "非独立" 形式。 具体针 对某一用户设备以何种形式服务可以有 Macro进行控制, 例如对以现有切换过程接入过来 的用户设备以 "独立,, 形式进行服务, 对与控制面和用户面分离切换过程" 接入进来的用 户设备以 "非独立" 形式进行服务。
考虑到实际部署场景和设备筒化, 通常 small cell由唯一确定的 Macro管理, 该 Macro cell也可称为 small cell的归属小区。 Small cell确定其归属的 Macro cell可以才 居地理位置 确定, 即 small cell部署在某个 Macro cell覆盖范围内, 就由该 Macro管理。 或者根据测量 到的 Macro cell的信号强度确定, 即 small cell 测量 Macro信号并获得 RSRP ( Reference signal received power, 参考信号接收功率 ), small cell将 RSRP最高的 Macro cell作为归属 小区。 当然不限于上述方法, 但无论哪种 small cell归属方法, 都可能存在一种情况, 即某 一 small cell下的用户设备根据 RSRP驻留的 Macro cell与 small cell归属的 Macro cell不同。 如图 1D所示, small cell 1和 small cell 2分别被 Macro cell 1和 Macro cell 2管理, UE根据 其 RSRP最大原则确定出归属的 small cell为 small cell 1 , 而 UE根据 RSRP最大原则驻留 的 Macro cell为 Macro cell 2。 而此时 small celll和 Macro cell2并没有管理 /归属的关系。
一^:情况下, 非独立工作的 small cell其小区 ID由其归属的 Macro cell统一分配和管 理, 即 Macro cell可以通过小区 ID唯一识别其管辖的任一 small celL 由于小区 ID的可用 范围有限, 在 small cell密集部署时, 不同的 Macro cell之内可能重用相同的小区 ID。驻留 在 Macro cell中的用户设备根据 Macro cell的辅助配置, 对 small cell进行发现和测量, 并 将测量结果上报给 Macro cell,由 Macro cell根据业务传输需要为该用户设备选择用于业务 传输的 small celL
当用户设备驻留的 Macro cell与用户设备接收到 RSRP最强的 small cell两个小区之间 并没有归属 /管理关系时, 如果用户设备按照现有技术将测量 RSRP和相应的小区 ID—并 上 4艮给其驻留的 Macro cell。此时用户设备测量的 small cell小区 ID实际是由另一 Macro cell 管理和分配的,而接收到小区测量上报的 Macro cell小区中可能已将该小区 ID分配给另一 small cell, 此时接收到小区测量上报的 Macro cell并不能识别出用户设备上报的测量量对 应哪个 small cell , 也就不能够正确的为用户设备选择合适的 small cell进行业务传输。
综上所述, 目前 small cell ID重叠, 以及承载分离或切换不合理导致的传输性能下降。 目前没有一种判断 small cell是否具有独立属性的方案。 发明内容

本发明实施例连接处理的方法、 系统及设备中, 由于用户设备根据第一 Small cell归 属的 Macro cell进行小区测量上报并根据第二 Macro cell的指示进行 Small cell接入,从而, 一方面, Small cell不仅可以通过 Small cell ID进行区别,还可以进一步通过归属 Macro cell 信息加以区别,这样就避免了 Small cell lD 重叠导致的无法识别小区的问题;另外一方面, 根据 Small cell归属的 Macro cell的信息,可以判定用户设备即将双连接的两个基站( Macro cell和 Small cell )是否存在交互通道以便支持双连接功能, 进而避免用户设备连接在两个 基站上, 但不能进行真正的双连接传输, 影响传输性能。
本发明实施例判断属性的方法及设备中,由于第二 Macro cell能够根据 Small cell是否 具有独立属性的信息判断归属于第一 Macro cell的 Small cell是否具有独立属性,从而实现 了判断 small cell是否具有独立属性。
small cell和 Macro cell之间可以通过承载分离为用户设备提供数据传输,并且该 Macro cell对 small cell进行管理, 则认为该 small cell归属于该 Macro celL 用户设备驻留在某个 Macro cell , 则认为该用户设备归属该 Macro cell。
其中, 本发明实施例中, 用户设备能够进行测量的 small cell归属于第一 Macro cell; 用户设备归属于第二 Macro cell。
下面结合说明书附图对本发明实施例作进一步详细描述。
在下面的说明过程中, 先从网络侧和用户设备侧的配合实施进行说明, 最后分别从网 络侧与用户设备侧的实施进行说明, 但这并不意味着二者必须配合实施, 实际上, 当网络 侧与用户设备侧分开实施时, 也解决了分别在网络侧、 用户设备侧所存在的问题, 只是二 者结合使用时, 会获得更好的技术效果。
如图 2所示, 本发明实施例连接处理的系统包括: Small cell 10, 用户设备 20和第二 Macro cell 20。
Small cell 10, 用于确定归属的第一 Macro cell , 发送第一 Macro cell信息;
用户设备 20,用于确定 small cell 10归属的第一 Macro cell的第一 Macro cell信息,根 据第一 Macro cell信息判决是否向用户设备 20归属的第二 Macro cell 30进行小区测量上 报, 或将第一 Macro cell信息上报给第二 Macro cell 30; 根据第二 Macro cell 30指示进行 承载分离或切换或保持承载连接不变;
第二 Macro cell 30, 用于接收归属于第二 Macro cell 30的用户设备 20上报的信息,根 据用户设备 20上报的信息, 指示用户设备 20进行承载分离或切换或保持承载连接不变。
其中, 本发明实施例中的 Macro cell信息可以是 Macro cell的小区标识, 也可以是能 够区分不同 Macro cell的信息。

隐式指示: 比如用户设备向用户设备归属的第二 Macro cell进行小区测量上报或将第 一 Macro cell信息上报之后,在设定时间内未收到第二 Macro cell的信息,确定第二 Macro cell指示保持承载连接不变。
在实施中, small cell 10发送第一 Macro cell信息的方式有很多种, 比如可以通过公共 信息发送第一 Macro cell信息, 相应的, 用户设备 20通过公共信息接收第一 Macro cell信 息; 还可以通过下行同步序列发送第一 Macro cell信息, 相应的, 用户设备 20通过检测下 行同步信号, 获取第一 Macro cell信息。
公共信息包括但不限于下列信息中的一种:
主信息块 ( Master Information Block, MIB )和系统信息块 ( System Information Block,
SIB )。
在实施中, 用户设备 20可以根据第一 Macro cell信息判决是否向用户设备 20归属的 第二 Macro cell 30进行小区测量上报, 或将第一 Macro cell信息上报给第二 Macro cell 30, 下面分别介绍。
情况一、用户设备 20根据第一 Macro cell信息判决是否向用户设备归属的第二 Macro cell 30进行小区测量上报:
具体的,用户设备 20通过物理层或高层获得第一 Macro cell信息,并根据该第一 Macro cell信息判断第一 Macro cell与第二 Macro cell 30是否相同;在确定第一 Macro cell与第二
Macro cell 30相同后, 向用户设备 20归属的第二 Macro cell 30进行小区测量上报。
用户设备 20通过高层判断第一 Macro cell与第二 Macro cell 30是否相同的方式有很多 种, 下面列举几种:
高层判断方式一、 用户设备 20 将通过公共信息接收的第一 Macro cell信息和第二 Macro cell信息(这里的第二 Macro cell信息是第二 Macro cell通知的 )比较,若第一 Macro cell信息与第二 Macro cell信息相同, 确定第一 Macro cell与第二 Macro cell相同。
高层判断方式二、用户设备 20通过检测下行同步信号得到的第一 Macro cell信息和第 二 Macro cell信息 (这里的第二 Macro cell信息是第二 Macro cell通知的) 比较, 若第一 Macro cell信息与第二 Macro cell信息相同, 确定第一 Macro cell与第二 Macro cell相同。
用户设备 20通过物理层判断第一 Macro cell与第二 Macro cell 30是否相同的方式有很 多种, 下面列举几种:
物理层判断方式一、 用户设备 20盲检下行同步信号找到匹配的第一 Macro cell信息, 若匹配的第一 Macro cell信息与第二 Macro cell信息 (这里的第二 Macro cell信息是第二 Macro cell通知的)相同, 确定第一 Macro cell与第二 Macro cell相同。

情况二、 用户设备 20将第一 Macro cell信息上 4艮给第二 Macro cell 30:
较佳地, 用户设备 20还将 small cell信息上报第二 Macro cell 30; 或
用户设备 20还将 small cell信息和 small cell测量结果上 4艮第二 Macro cell 30; 或 用户设备 20还将 small cell信息、 small cell测量结果和第一 Macro cell测量结果上 4艮 第二 Macro cell 30。
若用户设备 20上报第一 Macro cell信息和 small cell信息,第一 Macro cell信息和 small cell信息独立配置上 ·ί艮, 或统一配置上 ·ί艮;
若用户设备 20上 4艮第一 Macro cell信息、 small cell信息和 small cell测量结果, 第一
Macro cell信息、 small cell信息和 small cell测量结果独立配置上 ·ί艮, 或统一配置上 ·ί艮, 或 部分统一配置上 ·ί艮;
若用户设备 20上 4艮第一 Macro cell信息、 small cell信息、 small cell测量结果和第一 Macro cell测量结果、 第一 Macro cell信息、 small cell测量结果和第一 Macro cell测量结果 独立配置上 ·ί艮, 或统一配置上 ·ί艮, 或部分统一上 ·ί艮。
在实施中, 若用户设备 20根据第二 Macro cell 30指示保持承载连接不变, 则用户设 备 20可以判断 small cell是否具有独立属性; 若 small cell具有独立属性, 用户设备 20将 small cell作为独立小区进行小区测量上报; 否则不进行小区测量上报。
具有独立属性的 small cell包括仅具有独立属性, 以及具有非独立和独立属性两种。仅 具有独立属性的 small cell具有系统中一个小区的完整功能, 支持用户设备在 small cell中 接入和驻留,用户设备从 Macro基站移动到 small cell覆盖中需要经过切换过程。双重属性 的 small cell既能够支持独立工作的小区所应具有的所有功能, 包括允许用户设备驻留、为 用户设备提供完整的控制面和用户面连接; 同时也应具有不支持独立工作的小区应具有的 功能, 包括仅为用户设备提供用户面连接、 接受 Macro基站的配置和管理等。
对于第二 Macro cell 30, 接收到的用户设备 20上报的信息可以包括:
第一 Macro cell信息。
较佳地, 接收到的用户设备 20上报的信息还可以包括:
small cell信息; 或
small cell信息和 small cell测量结果; 或
small cell信息、 small cell测量结果和第一 Macro cell测量结果。
若用户设备 20上报的信息包括:第一 Macro cell信息和 small cell信息,第一 Macro cell 信息和 small cell信息独立配置上报, 或统一配置上报;

处理方式一、 用户设备上报的信息为第一 Macro cell信息。
具体的, 若第一 Macro cell信息和第二 Macro cell信息相同, 则第二 Macro cell 30指 示用户设备进行小区测量上报, 并根据上报的信息指示用户设备进行承载分离或保持承载 连接不变;
若第一 Macro cell信息和第二 Macro cell信息不同, 则第二 Macro cell 30指示用户设 备不需要小区测量上报, 且保持承载连接不变。
处理方式二、 用户设备上 ·ί艮的信息包括第一 Macro cell信息和 small cell信息。
具体的, 若第二 Macro cell与 small cell能够协作, 则第二 Macro cell 30指示用户设备 进行小区测量上报, 并根据上报的信息指示用户设备进行承载分离或保持承载连接不变; 若第一 Macro cell信息和第二 Macro cell信息不同且第二 Macro cell与 small cell不能 协作, 则第二 Macro cell 30指示用户设备不需要小区测量上报, 且保持承载连接不变。
Macro cell与 small cell协作:即 Macro cell和 small cell能够通过承载分离为用户设备 提供数据传输。
当 Macro cell与 small cell 能够交互时, 可以确定能够进行协作。
在实施中, 还可以根据需要设定其他协作条件, 比如 Macro cell与 small cell之间交互 可以在满足一定的时延要求下, 确定可以协作。 另外, Small cell可以和多个 Macro cell协 作, 也可以限定一个 Macro cell协作。
处理方式三、 用户设备上报的信息为第一 Macro cell信息和 small cell测量结果。
具体的, 若第一 Macro cell信息和第二 Macro cell信息相同或第二 Macro cell与 small cell能够协作(这里满足两个条件中的一个即可,条件 1 :第一 Macro cell信息和第二 Macro cell信息相同; 条件 2: 第二 Macro cell与 small cell能够协作), 则第二 Macro cell 30将 small cell作为备选承载分离小区,并根据 small cell测量结果进行承载分离判决并指示给用 户设备 30;
若第一 Macro cell信息和第二 Macro cell信息不同且第二 Macro cell与 small cell不能 协作, 则第二 Macro cell 30指示用户设备 30保持承载连接不变。
处理方式四、 第一 Macro cell信息, small cell测量结果和第一 Macro cell测量结果。 具体的, 若第一 Macro cell信息和第二 Macro cell信息相同或第二 Macro cell与 small cell能够协作, 则第二 Macro cell 30将 small cell作为备选承载分离小区, 并根据 small cell 测量结果进行承载分离判决并指示给用户设备;
若第一 Macro cell信息和第二 Macro cell信息不同且第二 Macro cell与 small cell不能 协作, 则第二 Macro cell 30根据第一 Macro cell测量结果和 /或 small cell测量结果判定是 否切换到第一 Macro celL
较佳地, 第二 Macro cell 30根据第一 Macro cell测量结果判定是否切换到第一 Macro cell时, 第二 Macro cell 30判断第一 Macro cell测量结果是否大于第一门限值; 若是, 则 指示用户设备切换至第一 Macro cell; 否则保持承载连接不变; 或第二 Macro cell 30判断 第一 Macro cell测量结果和用户设备上报的第二 Macro cell测量结果的差值的绝对值是否 大于第二门限值; 若是, 则指示用户设备切换至第一 Macro cell; 否则保持承载连接不变。
较佳地,第二 Macro cell 30根据第一 Macro cell测量结果和 small cell测量结果判定是 否切换到第一 Macro cell时,判断第一 Macro cell测量结果是否大于第一门限值 ,以及 small cell测量结果是否大于第三门限值,若两者都满足条件,则指示用户设备切换至第一 Macro cell; 否则保持承载连接不变;
较佳地,第二 Macro cell 30根据 small cell测量结果判定是否切换到第一 Macro cell时, 判断 small cell测量结果是否大于第四门限值, 若满足条件, 则指示用户设备切换至第一 Macro cell; 否则保持 载连接不变。
上述门限值可以根据需要、仿真等进行设置。较佳地, 第四门限值较正常切换门限高。 在实施中, 用户设备根据第二 Macro cell 的指示保持承载连接不变之后, 接收来自
Small cell的 Small cell是否具有独立属性的信息, 判断 small cell是否具有独立属性; 或 用户设备将接收来自 Small cell的 Small cell是否具有独立属性的信息发送给所述用户 设备归属的第二 Macro cell; 或
用户设备根据接收来自 Small cell的 Small cell是否具有独立属性的信息判定是否将 Small cell独立属性的信息通知所述第二 Macro celL
较佳地, 用户设备接收来自 Small cell的 Small cell是否具有独立属性的信息之后, 若 small cell具有独立属性, 将 small cell作为独立小区进行小区测量上报; 否则, 所述用户设 备不进行小区测量上报。
在实施中, 第二 Macro cell指示用户设备保持承载连接不变之后, 还可以判断归属于 第一 Macro cell的 Small cell是否具有独立属性。
其中, 第二 Macro cell判断 small cell是否具有独立属性的方式有很多种, 下面列举几 种:
判断方式一、 第二 Macro cell 30根据用户设备指示的 Small cell是否具有独立属性的 信息,判断 Small cell是否具有独立属性,判断 Small cell是否具有独立属性;其中 Small cell 是否具有独立属性的信息是 Small cell发送给用户设备 20的;
相应的, 用户设备 20可以显示指示或隐式 +显示指示。
显式指示: 用户设备将接收来自 Small cell的 Small cell是否具有独立属性的信息发送 给用户设备归属的第二 Macro cell 30; 隐式 +显示指示: 用户设备根据接收来自 Small cell的 Small cell是否具有独立属性的 信息判定是否将 Small cell独立属性的信息通知第二 Macro cell 30, 如果不发送, 则第二 Macro cell 30认为 Small cell不具有独立属性。
在实施中, 如果用户设备需要发送 Small cell是否具有独立属性的信息或 Small cell独 立属性的信息, 则该信息可以和其他一些测量量一起上报, 或独立上报。
判断方式二、第二 Macro cell 30根据通过第一 Macro cell获取的 Small cell是否具有独 立属性的信息, 判断 Small cell是否具有独立属性;
相应的, 第一 Macro cell确定属于 Small cell的 Small cell是否具有独立属性的信息, 向第二 Macro cell 30发送 Small cell是否具有独立属性的信息。
Small cell是否具有独立属性的信息可以是比特值, 比如 1代表可以, 0代表不可以; 也可以是其他能够表示 Small cell是否具有独立属性的信息。
针对判断方式二, 适用于 Small cell具有独立和非独立双重属性, 且对第二 Macro cell 30无法建立连接管理关系 (即无法进行非独立工作), 但对第一 Macro cell 30可以建立连 接管理关系 (即进行非独立工作)。

如图 9所示, 本发明实施例由用户设备通过高层进行判定的示意图中:
用户设备归属于 Macro cell 2; small cell 1与 Macro cell 1协作实现承载分离。
用户设备通过高层判断 Macro cell 1与 Macro cell 2是否相同,且在至少满足 Macro cell 1与第二 Macro cell 2相同后才进行上 ·ί艮。
具体的, 用户设备通过 Small cell 1获得其协作的 Macro cell 1的小区信息, 并和自身 的驻留 Macro cell 2的小区信息进行比较。 如果两者相同, 则将该 small cell 1纳入候选的 small cell列表,并将相应的测量结果以及 small cell 1 的 ID (也可以进一步包括该 small cell 1归属的 Macro cell ID 1)上报给驻留的 Macro cell 2; 否则, 用户设备不将该 small cell 1做 为备选的接入小区, 也不进行相应的小区测量上报。 通常地, 为了控制上报开销, 用户设 备侧可以根据预设的条件 (例如根据 RSRP最大原则、 RSRP高于预定门限原则等原则中的 一种)选择出有限的 small cell 进行检测或上报。
接收到小区测量上 4艮的 Macro cell 2在第一 Macro cell信息和第二 Macro cell信息相同 或第二 Macro cell与 small cell能够协作, 则将 small cell作为备选承载分离小区, 并根据 small cell测量结果进行承载分离判决并指示给用户设备; 在第一 Macro cell信息和第二 Macro cell信息不同且第二 Macro cell与 small cell不能协作, 则指示用户设备保持承载连 接不变。
如图 10所示, 本发明实施例由用户设备通过物理层进行判定的示意图中:
用户设备归属于 Macro cell 2; small cell 1与 Macro cell 1协作实现承载分离。
用户设备通过物理层判断 Macro cell 1与 Macro cell 2是否相同, 且在至少满足 Macro cell 1与 Macro cell 2相同后才进行上 ·ί艮。
具体的, 用户设备对 small cell 1的下行同步序列检测时, 直接判定该 small cell 1的归 属小区是否是 Macro cell 2。 如果是, 则将该 small cell 1纳入候选的 small cell列表, 并将 相应的测量结果以及 small cell 1 的 ID (也可以进一步包括该 small cell 1归属的 Macro cell ID 1)上报给驻留的 Macro cell 2, 否则, 用户设备不将该 small cell 1做为备选的接入小区, 也不进行相应的小区测量上报, 直到用户设备驻留小区发生变化。 通常地, 为了控制上报 开销, 用户设备侧可以根据预设的条件 (例如根据 RSRP最大原则、 RSRP高于预定门限原 则等原则中的一种)选择出有限的 small cell 进行检测或上报。
接收到小区测量上 4艮的 Macro cell 2在第一 Macro cell信息和第二 Macro cell信息相同 或第二 Macro cell与 small cell能够协作, 则将 small cell作为备选承载分离小区, 并根据 small cell测量结果进行承载分离判决并指示给用户设备; 在第一 Macro cell信息和第二 Macro cell信息不同且第二 Macro cell与 small cell不能协作, 则指示用户设备保持承载连 接不变。
用户设备对 small cell 1的下行同步序列检测并判定该 small cell 1的归属小区是否是 Macro cell2,较佳的方法为:用户设备检测下行同步序列时,将用户设备驻留小区 Macro cell 2的信息(如 Macro cell 2的 ID )作为一种先 -验信息, 即只盲检与 Macro cell 2的信息相关 的下行同步序列, 则可以保证用户设备检测到的 small cell 1都是属于该 Macro cell2的。
下面以基站进行判定为例, 对本发明的方案进行说明。
如图 11所示, 本发明实施例第一种由 Macro cell进行判定的示意图中:
用户设备归属于 Macro cell 2; small cell 1与 Macro cell 1协作实现承载分离。

接收到小区测量上报的 Macro cell 2查看上报内容中包含的 Macro cell 1的 ID是否与 本区 ID相同:
如果相同, 则根据上报的信息指示用户设备进行承载分离或保持承载连接不变; 如果不同, 则进一步查看本区与 small cell 1是否能够协同;
如果能, 则将 small cell作为备选承载分离小区, 并根据 small cell测量结果进行承载 分离判决并指示给用户设备;
如果不能建立连接, 则第二 Macro cell指示用户设备不需要小区测量上报, 且保持承 载连接不变。
较佳地, 如果不能建立连接可通知用户设备后续不上 4艮针对该 small cell的测量结果。 较佳地, 与 small cell 1建立连接和管理关系时, 可以直接建立与 small cell 1连接, 还 可以通过 Macro cell 1间接建立与 small cell 1连接。

如果相同, 则根据上报的信息指示用户设备进行承载分离或保持承载连接不变; 如果不同, 则进一步查看本区与 small cell 1是否能够协同;
如果能, 则将 small cell作为备选承载分离小区, 并根据 small cell测量结果进行承载 分离判决并指示给用户设备;
如果不能建立连接 , 则进一步根据切换策略进行切换判决。
较佳地, 切换策略包括但不限于下列中的至少一种:
切换策略 1 : 判断用户设备上报的针对 Macro cell 1和 Macro cell 2的测量结果 (例如 RSRP或参考信号接收盾量(Reference Signal Received Quality, RSRQ ) ), 当两者之差小 于第二门限值 (例如 3dB), 并且本区 (Macro cell 2)管辖的 small cell中没有适合为该用户传 输数据的小区时, 触发将用户设备切换至 Macro cell 1; 否则配置用户设备承载连接保持不 变。
切换策略 2: 判断用户设备上报的 Macro cell 1测量结果 (例如 RSRP或 RSRQ), 超过 第二门限值, 则切换到 Macro cell 1 ; 否则, 配置用户设备承载连接保持不变。
