Description

基站、 终端及自动邻区关系检测、 添加方法和*** 技术领域
本发明涉及通信领域， 具体涉及一种基站、 一种终端及一种自动邻区 关系检测、 添加方法和一种自动邻区关系检测、 添加***。 背景技术
在 E-UTRAN ( Evolved Universal Terrestrial Radio Access Network,演进 通用陆地无线接入网） ***中， 邻区关系的配置是为了保证终端在各网络 之间移动时， 能够及时切换到目标小区， 避免由于终端移动时因服务小区 信号质量变差而引起掉话。 合理的邻区关系配置能够有效保证网络切换成 功率， 提高用户的网络感受度。 但是在邻区关系配置过程中， 现有的做法 是将检测频点上所检测到的小区的小区信息全都上报给基站， 但对于某些 小区实际是基站所不需要的， 但由于终端的上报， 基站仍会将其添加到邻 区关系表中， 导致配置的邻区关系表中存在较多的冗余信息。 由于邻区关 系表中记录数的限制， 当存在较多的冗余信息时， 会导致合理的邻区无法 添加到邻区关系中， 进而影响到网络切换的效率及成功率， 降低用户体验 的满意度。
另外， 在邻区关系配置过程中， 还往往会出现正确的邻区关系没有被 添加到邻区关系中的情况， 导致终端在移动过程中， 当无线环境变化时， 无法正常完成小区切换而掉话。 特别对于存在异***邻区的场景， 终端只 能根据基站下发测量配置中携带的异***小区对异***中的邻区信号检 测， 但对于该基站未配置的异***小区， 终端不能主动发现并上报这类邻 区信息， 基站不能获取到未配置的异***中存在的邻区信息， 也就不能完 成其他异***中邻区 （例如包括 UTRA邻区、 CDMA2000邻区） 关系的自 动添加， 导致合理的邻区关系没有被添加到邻区关系中， 进而导致当终端 在网络中移动时， 因邻区关系配置不合理而导致切换失败， 大大降低了用 户体验的满意度。 发明内容

另外， 本发明中基站下发给终端的检测指令所包含的预设检测频点可 为与相应的异***相对应的频点， 即本发明中在检测异***的邻区时， 并 非只是检测基站上配置好的已知的异***中是否存在新的邻区， 而是检测 预设检测频点上的所有小区， 该频点上的小区自然可包括基站配置好的异 ***中的小区， 也可能包括基站未知的未配置好的异***中的小区， 而本 发明中， 只要是在该频点上的小区都会被检测到， 并根据预设的条件进行 筛选， 避免漏检测某一个或多个异***中的小区， 进而提高异***邻区关 系检测的成功率及正确率。
进一步的， 本发明中， 通过上述方法检测出新的邻区后， 可将检测出 的新的邻区进行添加， 以提高邻区关系优化效率， 进而提高终端移动时成 功切换的成功率， 以提高用户体验的满意度。 附图说明

由上述检测方法可知， 本例中在检测邻区时， 并非将在预设检测频点 上检测到的所有小区的小区信息发给基站， 而是仅将信号强度满足预设条 件的小区的小区信息发给基站， 因此可对检测出的小区根据信号强度关系 进行有效的筛选， 例如只上传信号强度最大的小区， 因此可大大减少邻区 关系配置过程中的冗余信息， 且可使终端在切换时， 能尽快的直接找到所 要切换的邻区， 提高终端切换的效率及成功率。
本例中， 基站下发给终端的检测指令中所包含的预设检测频点可为与 相应的异***相对应的频点， 以检测异***的小区； 也可为与自身***对 应的频点， 以检测***内的小区。
值得注意的是， 由于本例中检测的是预设检测频点上的小区， 当上述 预设检测频点为与相应的异***相对应的频点时， 终端所检测到的小区为 该频点上所有的小区， 这些小区既可能包括基站所配置好的异***中的小 区， 也可能包括基站未知的并未配置的异***的小区。 因此本例中的方法 检测到的新的邻区既可能是基站配置好的异***的小区， 也可能是基站未 知的并未配置好的异***的小区， 不管基站是否配置， 只要在该频点上有 小区信号， 都会被终端检测到， 因此本例中提供的方法可以提高异***邻 区关系检测的准确率。
本例中基站根据接收到的检测结果中包含的小区信息判断是否存在新 的邻区具体为： 根据接收到的检测结果中包括的小区信息和基站上存储的 邻区关系表中已有的邻区信息进行比较， 从而判断出检测结果中的小区信 息对应的小区是否是新的未知邻区。 优选的， 本例中的上述预设条件设为 信号强度在检测到小区中为最大， 即终端只将检测频点上各小区中信号强 度最大的小区的小区信息反馈给基站， 尽可能的简化邻区关系表中的信息， 较少邻区关系优化过程中的冗余信息； 基站则将该 ' j、区消息与邻区关系表 中已有的邻区信息进行比较， 判断该小区是否是新的未知小区。
值得注意的是， 本例中的预设条件并非只能为信号强度为检测到所有 小区中为最大， 该条件的具体设置可根据实际情况具体设置。 例如， 可设 置为检测到的小区中信号强度大于预设阈值， 即信号强度大于预设值的小 区都可被上报给基站。 阈值的选择则可参考终端切换时所要求的信号强度 等因素来设置。
本例中，基站下发给终端的检测指令优选为 reportStrongestCellsForSON 检测指令。 根据实际需要， 也可选择其他能通知终端在预设检测频点上进 行小区检测并按预设规则进行筛选的其他形式指令。
请参见图 2, 本例中的通过上述方法检测出新的邻区后，还可根据实际 情况对检测出的新的邻区做进一步处理， 例如将其添加到邻区关系表中， 将其添加到邻区关系表中的具体过程如下：
步驟 104,基站发送唯一标识信息查询指令给终端以查询检测出的新的 邻区的唯一标识信息；
步驟 105~106,终端接收到所述唯一标识信息查询指令后， 查询该新的 邻区的唯一标识信息， 并将查询结果反馈给基站；
步驟 107, 基站根据终端的查询结果添加检测出的新的邻区。
本例中， 终端根据接收到的唯一标识信息查询指令查询新的邻区的唯 一标识信息时， 如果成功检测到邻区的小区唯一标识信息， 则将该小区的 唯一标识信息携带在反馈给基站的查询结果中； 如检测邻区小区的唯一标 识信息失败， 则反馈给基站的查询结果中不携带小区唯一标识信息。
基站接收到终端反馈的查询结果后， 判断查询结果中是否携带有小区 的唯一标识信息， 如有， 则将检测到的新的邻区添加到邻区关系表中； 否 则， 不添加检测到的新的邻区到邻区关系表中， 结束此次流程。
本例中， 用于标识小区的唯一标识信息可根据实际情况具体选择， 本 例中优选用高层小区唯一标识信息来标识小区。
相应的， 本例中还提供了一种基站， 该基站包括自动邻区关系检测模 块， 用于下发包含预设检测频点的检测指令给终端， 以指示终端检测该频 点上的小区， 并根据终端反馈的以上所述的检测结果判断是否存在新的邻 区， 具体判断方法同上。
本例中的基站还可包括与自动邻区关系检测模块相连接的自动邻区关 系添加模块， 自动邻区关系检测模块还用于在检测到新的邻区后， 向终端 发送唯一标识信息查询指令查询检测到的新的邻区的唯一标识信息， 自动 邻区关系添加模块则用于根据终端反馈的查询结果添加新的邻区， 具体添 加方法也同上。
本例中还公开了一种终端， 用于按上述方法接收基站下发的包含预设 检测频点的检测指令， 根据该检测指令检测该频点上的小区， 将检测到的 小区中信号强度满足预设条件的小区的小区信息携带在检测结果中， 并将 该检测结果反馈给基站。
本例中的终端还用于按上述方法接收基站发送的唯一标识信息查询指 令， 根据该查询指令查询检测到的新的邻区的唯一标识信息， 并将查询结 果反馈给基站。
请参见图 3 , 图 3所示的为一种自动邻区关系检测***， 包括基站和至 少一个终端； 其中本例中的基站包括自动邻区关系检测模块， 用于按上述 方法下发包含预设检测频点的检测指令给终端， 并按上述方法根据终端反 馈的检测结果判断是否存在新的邻区；
终端用于按上述方法接收基站下发的包含预设检测频点的检测指令， 将检测到的小区中信号强度满足预设条件的小区的小区信息携带在检测结 果中， 并将该检测结果反馈给基站。
在图 3 所述的自动邻区关系检测***基础上， 本例还提供了一种自动 邻区关系添加***， 请参见图 4, 包括基站和至少一个终端； 其中基站包括 相互连接的自动邻区关系检测模块和自动邻区关系添加模块； 自动邻区关 系检测模块用于按上述方法下发包含预设检测频点的检测指令给终端， 根 据终端反馈的检测结果判断是否存在新的邻区； 并在检测到新的邻区后， 向终端发送唯一标识查询信息指令查询检测到的新的邻区的唯一标识信 息； 自动邻区关系添加模块则用于根据终端反馈的查询结果添加检测到的 新的邻区。
终端用于接收基站下发的包含预设检测频点的检测指令， 检测该频点 上的小区， 将检测到的小区中信号强度满足预设条件的小区的小区信息携 带在检测结果中， 并将该检测结果反馈给基站； 还用于接收到基站发送的 唯一标识信息查询指令后， 查询新的邻区的唯一标识信息， 并将查询结果 反馈给自动邻区关系添加模块， 以使自动邻区关系添加模块完成新的邻区 的添力口。
综上可知， 本发明提供的方法， 在检测邻区关系时， 并非将在检测频 点上检测到的所有小区的小区信息发给基站， 而是仅将信号强度满足预设 条件的小区的小区信息发给基站， 因此可大大减少邻区关系配置过程中的 冗余信息。
另外， 在发明中， 在检测异***的邻区关系时， 也是根据基站下发的 检测指令中包含的与异***相对应的频点， 检测该频点上的所有小区， 并 像现有的在检测频点上只检测基站下发测量配置中携带的小区， 导致基 站无法发现服务小区覆盖范围内的异***邻区信息； 避免漏检测某一个或 多个异***中的小区， 进而可提高异***邻区关系检测的正确率。 且本发 明中通过上述方法检测出新的邻区后， 可在进一步获取该邻区的唯一标识 信息后， 将其添加到邻区关系表中， 以提高邻区关系优化效率， 进而提高 终端移动时成功切换的成功率， 以提高用户体验的满意度。 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的 普通技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干简单 推演或替换， 都应当视为属于本发明的保护范围。
