本发明涉及小小区应用领域，尤其涉及一种接近指示（Proximity  Indication，PI）上报方法、系统及用户设备（User Equipment,UE）、网络设 备、计算机存储介质。
背景技术
随着无线多媒体业务的发展，人们对高数据速率和用户体验的需求日 益增长，从而对传统蜂窝网络的系统容量和覆盖提出了较高要求。在传统 长期演进（Long Term Evolution，LTE）蜂窝网络中，宏基站作为唯一的接 入侧网元为UE提供接入服务。而为了满足用户对较高数据速率的需求并提 高蜂窝网络频谱效率，3GPP引入了小小区（SMALL CELL）作为宏基站的 补充为UE提供接入服务。Small Cell源于最初为家庭场景设计的飞蜂窝 （Femtocell），Small Cell的“小”是相对于传统的宏基站（Macrocell）而 言的，其特点体现在：小型化、低发射功率、可控性好、智能化和组网灵 活。从发射功率看，典型发射功率在100mW到5W之间；从重量看，普遍 重量在2到10kg之间；从组网方式看，支持包括数字用户环路（Digital  Subscriberloop，DSL）/光纤/无线局域网络(Wireless Local Area Networks， WLAN)及蜂窝技术在内的多种技术的回传；而且还具备自动邻区发现、自 配置等SON功能。
Small Cell具有四类产品形态：第一种称为FemtoCell，主要用于家庭 和企业环境中；第二种称为微微小区（PicoCell），应用于室内公共场所如 机场、火车站、购物中心等；第三种称为微蜂窝（MicroCell），用于受限于 占地无法部署宏基站的市区或农村；最后一种称为宏蜂窝（MetroCell），主 要用于市区热点区域来降低容量瓶颈或农村。小小区网络环境示意图见图 1，如图1所示，小小区网络环境非常复杂，且小小区基站设备数量比传统 宏基站网络有明显的数量级的增长。
自2007年9月Sprint全球首家部署Femtocell以来，Small Cell已成功 在23个国家的41张网络中部署，目前全球部署量超过380万台，主要以 Femtocell的形态存在（占80%）。而从地区分布来看，主要分布在美国（Sprint 部署超过90万台\AT&T部署约50万台）、欧洲和日韩（日本软银部署12 万台）。
在热点部署场景下，为了达到较高的数据速率和频谱效率，需要在区 域内密集大量部署小基站，并且宏基站与小基站有可能采用不同频点，小 基站之间也有可能采用不同频点。特别的，在室内部署场景，如办公室、 商场等通常为多楼层建筑，不同楼层均可能有小基站部署，而不同楼层的 小基站工作载频可能并不相同。
在现有的封闭用户组（Closed Subsciber Group，CSG）家庭基站环境下， 为了实现UE及时从宏基站切换到CSG家庭基站，采用PI上报的方法。现 有方法中，UE离开或者进入一个或者多个CSG成员小区范围内触发PI上 报。而对于UE如何触发PI上报属于内部实现，目前标准没有具体规范。 比如UE可以利用自身的位置信息以及之前保存的进入过的CSG小区的频 点、演进小区全局标志符（E-UTRAN Cell Global ID，ECGI）、物理小区标 志符（Physical Cell ID，PCI）、位置信息、CSG ID等相关信息来进行进入 或者离开一个或者多个CSG小区覆盖范围的判断并触发上报PI。同时，网 络侧在无线资源控制（Radio Resource Control，RRC）连接重配消息中有简 单的PI上报控制指示信息指示用来指示UE开启或者停止LTE系统或者 UTRAN系统的PI上报。UE上报PI后，网络侧根据PI里携带的频点、RAT 信息来进行测量控制命令下发，UE将测量结果上报后可用于切换判决触 发。
由于Small Cell目前并没有CSG概念，那么UE可以依靠自身footprint 里保存的历史进入Small Cell小区信息进行触发判决。但是基于上述触发方 式，由于Small Cell的数量非常大(相比CSG成员小区)，因此UE依靠这种 自主的判决信息进行上报PI会导致大量的PI信息上报，尽管目前网络侧有 简单的控制方式，但是对于复杂的Small Cell网络环境，需要考虑更为合理 的PI上报控制和获取方法，比如在SCE场景下由于密集小小区的部署，需 要考虑针对不同类型、地理位置实现终端准确上报所需的小小区信息，以 避免对空口信令资源造成冲击，同时提高PI信息上报的准确性和实现上报 信息的有效利用。
