下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进 行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没 有做出创造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的 范围。
参见图 1 ,是本发明实施例提供的集中式组网的方法的第一实施例流程 示意图。 本实施例中所描述的集中式组网的方法, 包括步骤:
S101 , 根据获取到的预设区域中各个微基站的信息, 从所述各个微基 站中选出满足预设条件的微基站作为所述预设区域的微基站协调器。
具体实现中, 终端设备选出微基站协调器之前, 若密集部署场景中有 宏基站覆盖, 则需首先通过宏基站跟预设区域(即密集部署场景中所有微 基站组成的区域) 中的微基站建立通信连接, 获取各个微基站的信息。 其 中, 上述终端设备, 可包括: 宏基站、 预设区域中的微基站等。 例如, 宏 基站可通过回程连接与微基站建立连接, 通过回程连接与微基站通信, 获 取微基站的信息; 若密集部署场景中没有宏基站覆盖, 终端设备则需要接 收预设区域中的各个微基站的广播信息, 从各个微基站的广播信息中获取 各个微基站的信息。 其中, 获取到的微基站信息, 可包括: 微基站的特定 信道或信号的发射功率、 微基站的覆盖范围、 微基站的回程连接时延、 微 基站的位置 (例如, 微基站与宏基站的距离、 微基站在上述预设区域中的 位置等)等。 终端设备获取到各个微基站的信息之后, 则可从各个微基站 中选出满足预设条件的微基站作为上述预设区域的微基站协调器。 例如, 可从获取到的各个微基站的信息中选择距离宏基站最近的微基站作为协调 器, 或者从各个微基站中选择覆盖范围最大, 或者特定信道或信号 (如同 步信道、 广播信道、 下行控制信道、 下行数据信道、 CRS ( Commonality Reference Signal, 公共参考信号)、 DMRS ( Demodulation Reference Signal , 解调参考信号)、 CSI-RS ( Channel State Indication Reference Signal, 信道状 态信息参考信号)等)发射功率最大的微基站作为协调器, 或者从各个微 基站中选择与宏基站或者邻居微基站的回程时延最小的微基站作为协调器 等。
S102 , 将所述作为协调器的微基站设定为簇头, 所述预设区域中的其 他微基站为簇员, 建立集中式网络, 其中, 所述簇头用于向所述簇员发送 信息。
终端设备选出可作为协调器的微基站之后, 则可将上述作为协调器的 微基站设定为簇头, 并以该预设区域中的其他微基站为簇员, 建立集中式 网络。 集中式网络组建完成之后, 作为协调器的微基站可从宏基站处获取 整个簇的时频资源、 干扰信息、 定时同步、 功率控制参数等信息, 并将获 取到的信息下发给其他微基站, 行使协调器的功能, 其中, 上述协调器的 功能包含但不限于时频资源分配、 小区 ID分配、 下行功率控制等。 若密集 部署中没有宏覆盖, 即密集部署中没有宏基站, 则可通过协调器来自定义 整个簇的时频资源、 定时同步、 功率控制参数等信息, 并通过作为协调器 的微基站来行使协调器的功能,包含但不限于时频资源分配、小区 ID分配、 同步、 下行功率控制等。
本实施例可从密集部署的微基站中选择一个微基站作为协调器, 通过 作为协调器的微基站向密集部署的其他微基站发送信息, 行使协调器的功 能, 解决的微基站密集成簇的问题, 从而避免基站之间的相互干扰, 增强 了基站的用户体验效果。
参见图 2,是本发明实施例提供的集中式组网的方法的第二实施例流程 示意图。 本实施例中所描述的集中式组网的方法, 包括步骤: S201 , 与所述预设区域中的微基站建立通信连接, 并从所述微基站获 取所述微基站的信息。
具体实现中, 上述预设区域主要为密集部署的微基站组成的区域, 该 区域中有宏覆盖, 即密集部署的微基站可从与宏基站通信, 从宏基站处获 取信息。 具体的, 宏基站可首先与密集部署的微基站建立通信连接, 可通 过回程连接与密集部署的微基站进行通信, 获取各个微基站的信息。 其中, 上述微基站的信息, 可包括: 微基站的位置、 所述微基站的覆盖范围、 微 基站的回程连接时延、 微基站的特定信道或信号的发射功率、 微基站的接 收能力等, 即微基站与宏基站的距离、 微基站与宏基站的回程连接时延、 微基站的覆盖范围、 微基站的特定信道或信号的发射功率、 微基站的接收 能力等。 宏基站获取到各个微基站的信息之后, 则可根据各个微基站的信 息做决断, 选出密集部署的微基站的协调器。 具体实现中, 密集部署中有 一些微基站与宏基站之间没有回程连接, 宏基站无法通过回程连接获取到 这些微基站的信息, 进而无法根据这些微基站的信息做决断, 这些微基站 则无法成为协调器。
S202, 根据获取到的信息从所述各个微基站中选出满足预设条件的微 基站。
S203 , 判断所述满足预设条件的微基站是否多于一个, 若判断结果为 否, 则执行步骤 S204 , 若判断结果为是, 则执行步骤 S205。
S204, 将所述满足预设条件的微基站作为所述预设区域的微基站协调 器。
S205 , 从所述多个满足预设条件的微基站中选择一个微基站作为所述 预设区域的微基站协调器。
宏基站获取到上述各个微基站的信息之后, 则可根据各个微基站的信 息选择一个满足预设条件的微基站作为密集部署的微基站协调器。 其中, 上述预设条件, 可包括: 与宏基站的距离最近、 处于上述预设区域的中心 位置、 覆盖范围最大、 特定信道或信号的发射功率最大、 与宏基站的回程 连接时延最小、 具有宏基站使用的频率的接收能力等。 具体的, 预设条件 可为上述预设条件中的一个或者多个组合。 宏基站根据获取到的各个微基 站的信息选出满足上述预设条件的微基站, 若满足预设条件的微基站有多 个, 则从满足预设条件的多个微基站中选择一个作为密集部署的微基站中 的协调器, 若没有多个微基站同时满足预设条件, 即满足预设条件的微基 站只有一个, 则将该 基站作为密集部署的 基站中的协调器。 例如, 当 宏基站根据获取到的微基站的信息判断得知距离宏基站最近的微基站有多 个, 则可根据各个微基站的 CRS或其他参考信号发射功率从多个微基站中 选择 CRS或其他参考信号发射功率最大, 即覆盖范围最大的微基站作为协 调器。 如果根据上述多个预设条件选出的微基站有多个, 即有多个条件相 同的微基站, 则可由宏基站选择具体哪一个微基站作为密集部署的微基站 的协调器。
S206, 将所述作为协调器的微基站设定为簇头, 所述预设区域中的其 他微基站为簇员, 建立集中式网络, 其中, 所述簇头用于向所述簇员发送 信息。
宏基站选出可作为协调器的微基站之后, 则可将选中的微基站通知给 预设区域内的其他微基站, 即密集部署中的其他微基站, 并将上述作为协 调器的微基站设定为簇头, 以该预设区域中的其他微基站为簇员, 建立集 中式网络。 集中式网络组建完成之后, 作为协调器的微基站可从宏基站处 获取整个簇的时频资源、 干扰信息、 定时同步、 功率控制参数等信息, 并 将获取到的信息下发给其他微基站, 行使协调器的功能, 其中, 上述协调 器的功能包含但不限于时频资源分配、 小区 ID分配、 下行功率控制等。 此 外, 密集部署中的微基站中与宏基站没有回程连接的微基站也可以加入到 集中式网络中, 即可以成为簇员, 并可从协调器处获取时频资源、 干扰信 息、 定时同步以及功率控制参数等信息, 使得密集部署中没有与宏基站回 程连接的微基站也能成功获取信息, 正常运作。
本实施例可通过宏基站从密集部署的微基站中选择一个微基站作为协 调器, 通过作为协调器的微基站向密集部署的其他微基站发送信息, 行使 协调器的功能。 本实施例可通过作为协调器的微基站向密集部署的微基站 发送信息, 这些微基站中包括与宏基站有回程连接的微基站和与宏基站没 有回程连接的微基站, 即密集部署中的微基站无需每一个都与宏基站进行 通信, 只需要与协调器建立连接, 解决了微基站密集成簇的问题的同时也 减少了基站之间的接口控制信令的开销, 降低了宏基站与微基站之间相互 干扰的风险, 增强了基站的用户体验效果。
参见图 3 ,是本发明实施例提供的集中式组网的方法的第三实施例流程 示意图。 本实施例中所描述的集中式组网的方法, 包括步骤:
S301 , 接收所述预设区域中各个微基站的广播信息, 并从所述广播信 息中获取所述各个微基站的信息。
具体实现中, 上述预设区域主要为密集部署的微基站组成的区域, 该 区域中没有宏覆盖, 微基站之间需要互相传递信息, 通过自组织的方式来 选出密集部署的微基站的协调器。 具体的, 密集部署的微基站 (预设区域 中的微基站)之间可互相广播自身的信息。 密集部署中的微基站接收到预 设区域中各个微基站 (密集部署中的其他微基站) 的广播信息, 并从接收 到的广播信息中获取各个微基站 (密集部署中的其他微基站) 的信息。 其 中, 上述微基站的信息, 可包括: 微基站是否具有获得定时同步源的条件、 微基站的一跳邻居数量、 微基站的特定信道或信号的发射功率、 微基站与 预设区域中其他微基站的平均回程时延、 所述微基站的处理能力 (例如微 基站自身的处理能力, 包括基带处理能力、 射频处理能力、 天线数等)等。 上述微基站的信息仅是举例, 而非穷举, 包含但不限于上述微基站的信息。 此外, 微基站在相互传递信息时, 还可将自己接收到的一跳邻居的各方面 信息转发给周围的邻居微基站, 并接收周围邻居转发的二跳邻居的各方面 信息, 直到在预设范围 (一个小范围) 内没有再接收到新的微基站信息, 从而使得不能直接进行通信的微基站之间也能获得各自的信息。 其中, 上 述一跳邻居指的是可以直接进行通信的邻居, 二跳邻居指的是需要通过一 跳邻居获取到相关信息的邻居, 即需要间接获取信息的邻居。 微基站获取 到其他微基站的信息之后, 则可根据获取到的微基站的信息进行决断, 选 出可作为协调器的微基站。
S302, 根据获取到的信息从所述各个微基站中选出满足预设条件的微 基站。
S303 , 判断所述满足预设条件的微基站是否多于一个, 若判断结果为 否, 则执行步骤 S304 , 若判断结果为是, 则执行步骤 S305。

终端设备选出可作为协调器的微基站之后, 则可将选中的微基站通知 给预设区域内的其他微基站, 即密集部署中的其他微基站, 并通过组建模 块 60将上述作为协调器的微基站设定为簇头, 以该预设区域中的其他微基 站为簇员, 建立集中式网络。 集中式网络组建完成之后, 作为协调器的微 基站可从宏基站处获取整个簇的时频资源、 干扰信息、 定时同步、 功率控 制参数等信息, 并将获取到的信息下发给其他微基站, 行使协调器的功能, 其中, 上述协调器的功能包含但不限于时频资源分配、 小区 ID分配、 下行 功率控制等。 此外, 密集部署中的微基站中与宏基站没有回程连接的微基 站也可以加入到集中式网络中, 即可以成为簇员, 并可从协调器处获取时 频资源、 干扰信息、 定时同步以及功率控制参数等信息, 使得密集部署中 没有与宏基站回程连接的微基站也能成功获取信息, 正常运作。 具体实现 中, 上述组建模块如何建立集中式网络, 以及如何通过簇头行使协调器的 功能的具体实现过程可参见本发明实施例中提供的集中式组网的方法的第 二实施例中的步骤 S206, 再次不再赘述。
本实施例中所描述的终端设备可从密集部署的微基站中选择一个微基 站作为协调器, 通过作为协调器的微基站向密集部署的其他微基站发送信 息, 行使协调器的功能。 本实施例中所描述的终端设备可选择一个微基站 作为协调器, 并通过作为协调器的微基站向密集部署的微基站发送信息 , 这些微基站中包括与宏基站有回程连接的微基站和与宏基站没有回程连接 的微基站, 即密集部署中的微基站无需每一个都与宏基站进行通信, 只需 要与协调器建立连接。 本实施例中所描述的终端设备解决了微基站密集成 簇的问题的同时也减少了基站之间的接口控制信令的开销, 降低了宏基站 与微基站之间相互干扰的风险, 增强了终端设备的用户体验效果。

在一些可行的实施方式中, 若上述密集部署场景下的微基站没有宏覆 盖, 则该场景下的微基站则需要通过自组织的方式来选出密集部署的微基 站的协调器。 在一些可行的实施方式中, 所述终端设备, 还包括:
接收器, 用于接收所述预设区域中各个微基站的广播信息, 并从所述 广播信息中获取所述各个微基站的信息。
具体实现中, 密集部署的微基站 (预设区域中的微基站)之间可互相 广播自身的信息。终端设备的处理器 100接收到预设区域中各个微基站(密 集部署中的其他微基站) 的广播信息, 并从接收到的广播信息中获取各个 微基站 (密集部署中的其他微基站) 的信息。 其中, 上述微基站的信息, 可包括: 微基站是否具有获得定时同步源的条件、 微基站的一跳邻居数量、 微基站的发送功率、 微基站与预设区域中其他微基站的平均回程时延、 所 述微基站的处理能力 (例如微基站自身的处理能力, 包括基带处理能力、 射频处理能力、 天线数等)等。 上述微基站的信息仅是举例, 而非穷举, 包含但不限于上述微基站的信息。 此外, 微基站在相互传递信息时, 还可 将自己接收到的一跳邻居的各方面信息转发给周围的邻居微基站, 并接收 周围邻居转发的二跳邻居的各方面信息, 直到在预设范围 (一个小范围) 内没有再接收到新的微基站信息, 从而使得不能直接进行通信的微基站之 间也能获得各自的信息。 其中, 上述一跳邻居指的是可以直接进行通信、 获取信息的邻居, 二跳邻居指的是需要通过一跳邻居获取到相关信息的邻 居, 即需要间接获取信息的邻居。 处理器 100获取到各个微基站的信息之 后, 则可根据获取到的微基站的信息进行决断, 选出可作为协调器的微基 站。 具体实现中, 终端设备中的接收器如何获取各个微基站的信息的实现 过程可参见本发明实施例中提供的集中式组网的方法的第三实施例中的步 骤 S301 , 在此不再赘述。
在一些可行的实施方式中, 所述处理器在根据获取到的预设区域中各 个微基站的信息, 从所述各个微基站中选出满足预设条件的微基站作为所 述预设区域的微基站协调器时, 还具体用于:
根据所述接收器获取到的信息从所述各个微基站中选出满足预设条件 的微基站;
判断所述满足预设条件的微基站是否多于一个, 若判断结果为否, 则 将所述满足预设条件的微基站作为所述预设区域的候选协调器, 若判断结 果为是, 则从所述满足预设条件的微基站中选择一个微基站作为所述预设 区域的候选协调器;
结合所述预设区域中其他微基站选定的候选协调器选出被选定为候 选协调器得票最高的微基站作为所述预设区域的微基站协调器。
终端设备的处理器 100获取到的各个微基站的信息之后, 则可对获取 到的各个微基站的信息进行比较, 选择满足预设条件的微基站作为密集部 署的微基站的协调器。 其中, 上述预设条件, 可包括: 一跳邻居数量最多、 具有获得定时同步源的条件、 特定信道或信号的发射功率最大, 与预设区 域中其他微基站的平均时延最小、 处理能力最强 (微基站自身的处理能力, 包括基带处理能力、 射频处理能力、 天线数等)等。 具体实现中, 终端设 备选择协调器时进行比较、 判断的预设条件可为上述预设条件中的一个或 者多个组合。 终端设备的处理器 100根据获取到的信息从上述各个微基站 中选择满足预设条件的微基站之后, 则可将选择的微基站作为密集部署的 微基站的候选协调器 , 以结合其他微基站中选择的候选协调器最终抉择出 密集部署的微基站的协调器, 行使协调器的功能。 具体的, 处理器 100可 从各个微基站中选出满足预设条件的微基站, 并判断选出的满足预设条件 的微基站是否多于一个。 当处理器 100判断得知选择的满足预设条件的微 基站有多个时, 处理器 100则可从满足预设条件的多个微基站中选择一个 微基站作为该预设区域的候选协调器。 例如, 当处理器 100判断得知一跳 邻居最多的微基站有多个时, 则可从多个微基站中选择能够获得定时同步 源的微基站作为候选协调器。 当在限定的条件下, 满足多个预设条件的微 基站的个数多于一个, 处理器 100则可从满足预设条件的多个微基站中随 机选择具体一个微基站作为预设区域的候选协调器。 处理器 100根据自己 获取的信息进行判断和选择, 得到自己选定的候选协调器之后, 则可将自 己选定的候选协调器的广播给其他的微基站, 并接收其他微基站的广播信 息, 接收邻居微基站的候选协调器信息。 处理器 100接收到邻居的候选协 调器之后, 则可将获取到的其他微基站的候选协调器跟自身选择的候选协 调器进行比较, 当比较得知接收到的邻居候选协调器中有两个或者两个以 上相同, 并且与自己选择的候选协调器不同时, 则更改自己的候选协调器。 当比较得知有多个这样的候选协调器 (满足有两个或者两个以上的邻居选 择了该微基站作为候选协调器) 时, 则选择被选定为候选协调器得票最高 的微基站作为自己新的候选协调器, 直至全网统一, 并以该微基站作为该 预设区域的微基站协调器。 具体实现中, 上述处理器如何选出密集部署场 景中的协调器的实现过程可参见本发明实施例中提供的集中式组网的方法 的第三实施例中的步骤 S302-S306, 再次不再赘述。
处理器 100选定可作为协调器的微基站之后, 则可将自身的信息发送 给预设区域内的其他微基站, 即密集部署中的其他微基站。 此外, 处理器 100 选定了微基站协调器之后, 则可将上述作为协调器的微基站设定为簇 头, 以该预设区域中的其他微基站为簇员, 建立集中式网络。 当密集部署 的微基站有宏覆盖时, 处理器 100组建好集中式网络之后, 作为协调器的 微基站则可从宏基站处获取整个簇的时频资源、 干扰信息、 定时同步、 功 率控制参数等信息, 并将上述信息下发给密集部署中其他微基站, 行使协 调器的功能。 具体实现过程可参见本发明实施例提供的集中式组网的方法 的第二实施例中的步骤 S206, 在此不再赘述。 当密集部署的微基站没有宏 覆盖时, 处理器 100组建好集中式网络之后, 作为协调器的微基站则可自 行定义整个簇的时频资源、 干扰信息、 定时同步、 功率控制参数等信息, 并将上述信息下发给其他微基站, 行使协调器的功能, 其中, 上述协调器 的功能包含但不限于时频资源分配、 小区 ID分配、 下行功率控制等。 实现 过程可参见本发明实施例中提供的集中式组网的方法的第三实施例中的步 骤 S307 , 在此不再赘述。 此外, 当密集部署的微基站有宏覆盖时, 密集部 署的微基站中与宏基站没有回程连接, 而与作为协调器的微基站有回程连 接的微基站也可作为簇员, 加入到集中式网络中。 可从协调器获取相应的 信息。 当密集部署中的微基站没有宏覆盖时, 密集部署的微基站中与协调 器有回程连接的微基站均可以加入到集中式网络中, 即可以成为簇员, 并 可从协调器处获取时频资源、 干扰信息、 定时同步以及功率控制参数等信 息, 使得与协调器有回程连接的微基站均能成功获取信息, 正常运作。
本实施例中所描述的终端设备可通过宏基站选择一个微基站作为协调 器, 也可通过微基站自组织的方式从密集部署的微基站中选择一个微基站 作为协调器, 通过作为协调器的微基站向密集部署的其他微基站发送信息, 行使协调器的功能。 本实施例中所描述的终端设备可从宏基站中获取整个 簇的时频资源、 功率控制参数等信息, 也可自定义上述信息, 并向密集部 署的微基站发送上述信息, 使得即使没有宏覆盖, 密集部署中的微基站也 能正常运作, 解决了微基站密集成簇的问题的同时也解决了密集部署中没 有宏覆盖的问题, 提高了基站的适用性, 增强了基站的用户体验效果。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流 程, 是可以通过计算机程序来指令相关的硬件来完成, 所述的程序可存储 于计算机可读取存储介质中, 该程序在执行时, 可包括如上述各方法的实 施例的流程。 其中, 所述的存储介质可为磁碟、 光盘、 只读存储记忆体
RAM )等。
以上所揭露的仅为本发明较佳实施例而已, 当然不能以此来限定本发 明之权利范围, 因此依本发明权利要求所作的等同变化, 仍属本发明所涵 盖的范围。
