Description

位置相关信息的发送方法及系统、 处理方法及系统 技术领域
本发明涉及无线通信技术领域, 尤其涉及一种在无线通信系统中仔基 站的位置相关信息的发送方法及系统、 针对仔基站的位置相关信息的处理 方法及系统。 背景技术
无线通信系统中, 所谓基站指给终端提供服务的设备, 基站与终端之 间通过电磁波进行无线通信。 无线通信系统通过基站可以为基站信号所覆 盖地理范围内的终端提供无线覆盖, 这个地理范围称为小区。
通常, 无线通信系统为了能够大范围地为终端提供无线通信, 需要部 署覆盖范围大的基站, 这种基站通常称为宏基站, 宏基站所覆盖的小区通 常称为宏区 (Macrocell )。 同时, 无线通信系统考虑到终端的不同需求和不 同使用环境, 需要在某些环境或者场景下为终端提供更高质量的无线通信 服务, 一些覆盖范围小、 发射功率较低的基站因而被采用, 这些小型基站 包括小基站、 微基站和仔基站。 仔基站也可以称为家庭基站、 个人基站或 微基站。 宏基站是在室外环境下使用的无线接入设备, 而仔基站区别于宏 基站, 是在室内环境下使用的无线接入设备, 通过在无线通信系统中部署 仔基站, 可以为家庭或家庭式办公环境(SOHO )提供高速和 /或专有的无 线通信服务。 仔基站所服务的小区称为仔区 (Femtocell ), 在仔区内接受服 务的终端通常是静止的或者仅以低速运动的, 例如, 终端以步行速度运动。 如图 1所示为一个无线通信系统的组成结构示意图, 图 1 中包括: 宏基站 11、 仔基站 21~仔基站 25、 终端 31。 宏基站 11所服务的小区以 al表示, 仔基站 21~仔基站 25所服务的小区以 bl~ b5表示。 一个宏基站最大可覆盖方圓 2至 3公里的区域, 而仔基站的覆盖范围 不超过 30米。 由于它们覆盖范围的巨大差别, 在宏基站的覆盖范围内可能 部署有大量的仔基站, 比如几百甚至上千的仔基站以改善室内的通信服务 质量。 仔基站可同时接入的终端的最大个数通常为 6个到 8个。 仔基站通 常也分为开放的和专有的两种。 在不超过终端的最大个数的前提下, 开放 的仔基站可以对任何终端接入; 而专有的仔基站只对专有的终端开放, 其 他终端即使在专有的仔基站覆盖区也不能接入专有的仔基站。
在一个由宏基站以及大量被宏基站覆盖的仔基站的无线通信系统中, 为了保证承诺的服务质量, 当终端能够从仔基站获得服务时, 仔基站就应 替代宏基站为终端提供通信服务, 并将终端由宏基站切换到仔基站。 而终 端能够从仔基站获得服务的前提条件包括: 仔基站是终端可以接入的, 即 仔基站是终端获得授权的专有仔基站或者仔基站是开放的 , 仔基站还可以 接入新的终端, 而且终端已经进入仔基站的服务区。
在现有技术中, 为了便于终端接入和 /或切换到仔基站, 无线通信系统 为终端提供了一些仔基站的相关信息, 提供的相关信息中包括仔基站的通 信信息, 例如载频、 前导、 基站标识号、 小区负载等可用于通信的通信信 息, 同时也隐含了: 系统提供的仔基站是终端可接入仔基站的这样的前提 条件。 由于仔基站的覆盖范围很小, 而宏基站的覆盖范围很大, 终端能否 接入仔基站很大程度上取决于终端是否进入了仔基站的服务区。 如果能知 道仔基站相对于终端的位置, 就能由此方便地知道终端是否进入了仔基站 的服务区, 然而现有无线通信系统并没有在仔基站的相关信息中提供用以 标识仔基站位置的位置信息, 导致终端及其用户并不知道它能够接入的仔 基站的位置, 不利于终端接入和 /或切换到仔基站, 降低了系统的服务质量。
此外, 终端从宏基站接入和 /或切换到仔基站之前, 系统需要判断终端 是否进入仔基站的服务区, 当进入仔基站的服务区时执行接入和 /或切换。 现有技术中, 采用的判断方案是: 由终端尝试去检测仔基站的信号、 或者 由仔基站尝试去监听终端的信号。 采用现有判断方案尝试去检测或监听的 过程, 存在^艮大的不确定性, 而且这种尝试的过程造成系统一直处于工作 状态且耗时多, 会带来系统的使用效率不高及系统的额外开销较大等一系 列问题。
由于终端自身具备定位服务功能(LBS, Location-Based Service ) , 如 果从这个角度来考虑的话, 在 LBS的支持下终端的位置是可知的, 在此基 础上, 只需要再知道终端可接入的仔基站的位置, 就可以判断出终端是否 进入了仔基站的服务区, 也就是说终端可以根据仔基站的位置相关信息执 行扫描、 和 /或切换、 和 /或接入的处理。 这样, 既能增强判断的确定性, 又 能筒化判断且降低系统功耗和通信开销, 便于执行扫描、 和 /或切换、 和 / 或接入的处理。 目前, 针对这个涉及位置的考虑角度, 尚未有相对应的实 现方案。 发明内容
有鉴于此, 本发明的主要目的在于提供一种位置相关信息的发送方法 及系统, 在发送端发送仔基站的位置相关信息, 以便接收端获取仔基站的 位置相关信息, 以指导终端接入到仔基站、 和 /或终端切换到仔基站、 和 / 或终端定位到仔基站、 和 /或终端实现自身的定位, 改善系统的服务质量。
本发明的另一目的在于提供一种位置相关信息的处理方法及系统, 接 收端的终端根据仔基站的位置相关信息, 执行扫描、 和 /或切换、 和 /或接入 的处理, 既能增强判断的确定性, 又能筒化判断且降低系统功耗和通信开 销, 便于执行扫描、 和 /或切换、 和 /或接入的处理。

在全球微波接入互操作性 (WiMAX , Worldwide Interoperability for Microwave Access )通信网络中, 宏基站提供了较大范围的覆盖率, 而仔基 站则为终端提供在家庭或居家办公环境中的快捷灵活的通信服务。 当终端 从外面回家的时候, 为其服务的基站将从外面的宏基站切换为家里的仔基 站。 在切换准备时, 系统需要判断终端是否已经接近家里的仔基站, 当系 统判定终端已经接近仔基站时, 即终端已经进入仔基站的服务区时, 终端 将发起扫描和切换的过程。 而判断终端是否进入仔基站的服务区所采用的 现有判断方案, 都没有利用终端具备的 LBS, 造成系统的使用效率不高及 系统的额外开销较大等一系列问题。 如果从涉及位置的考虑角度来说, 在 LBS 的支持下终端的位置是可知的, 在此基础上, 只需要再知道终端可接 入的仔基站的位置, 就可以判断出终端是否进入了仔基站的服务区。 举例 来说, 对于终端由宏基站切换到仔基站的情况, 如果能获得终端与仔基站 之间的距离, 通过判断距离是否落在当前终端要接入仔基站的信号覆盖范 围内, 就可以判断出终端是否进入仔基站的服务区了。 比如, 仔基站的信 号覆盖范围为 20m, 当终端与仔基站之间的距离 <=20m, 就能判断出终端 已经进入仔基站的服务区了。 而本发明正是与这个涉及位置的考虑角度相 对应的两种实现方案。 采用本发明的两种实现方案, 既能增强判断的确定 性, 又能筒化判断且降低系统功耗和通信开销, 从而能避免系统的使用效 率不高以及系统的额外开销较大等一系列问题,便于执行扫描、和 /或切换、 和 /或接入的处理。 也就是说, 采用本发明的两种实现方案, 可以减小终端 扫描相关仔基站的时间和资源占用开销; 改善无线通信系统扫描、 接入和 切换性能; 以及降低通信和系统的资源占用开销。 附图说明
