Description

一种主动通知资源状态的方法和装置 技术领域
本发明涉及长期演进( LTE, Long Term Evolution )系统中演进型基站( eNB , evolved Node B )之间的信息交互技术,尤其涉及一种主动通知资源状态的方法 和装置。 背景技术
在 LTE 系统中, eNB 可以通过发送资源状态请求 RESOURCE STATUS REQUEST消息给邻近的 eNB, 通知邻近的 eNB根据消息中指示的内容进行资 源的测量; 其中, RESOURCE STATUS REQUEST消息中包括的主要信息有: 开始 /停止测量的标记、 需测量的资源的类别、 需要进行资源测量的小区、 以及 测量的间隔时间等。 邻近的 eNB接收到 RESOURCE STATUS REQUEST消息 后, 回复资源状态响应 RESOURCE STATUS RESPONSE消息; 之后, 邻近的 eNB将根据 RESOURCE STATUS REQUEST消息中的信息进行资源的测量,并 以资源状态更新 RESOURCE STATUS UPDATE 消息将测量结果告知发送 RESOURCE STATUS REQUEST消息的 eNB。
在上述处理过程中, 当 eNB没有向邻近的 eNB发送 RESOURCE STATUS REQUEST消息时, 邻近的 eNB便无法向 eNB通知自己的资源状态。 如果邻近 的 eNB的资源已经处于紧张的情况, 但其他 eNB由于不知道邻近 eNB已处于 资源紧张的状态, 仍然有可能不断将新的用户设备(UE, User Equipment )切 入, 这样, 就会更加加大邻近的 eNB的负荷, P争低邻近 eNB中 UE的接入和切 入成功率。 发明内容
有鉴于此, 本发明实施例的主要目的在于提供一种主动通知资源状态的方 法和装置, 能够主动通知 eNB的资源使用状态,从而提高 eNB中 UE的接入和 切入成功率。
为达到上述目的, 本发明的技术方案是这样实现的:
本发明实施例提供了一种主动通知资源状态的方法, 所述方法包括: 检测当前 eNB的资源使用状态;
当检测到当前 eNB的资源使用状态满足告警条件时, 发送当前 eNB的资 源使用状态通知信息。
上述方案中, 所述发送当前 eNB的资源使用状态通知信息为: 向邻近 eNB 发送当前 eNB的资源使用状态通知信息。
上述方案中, 所述检测到当前 eNB的资源使用状态满足告警条件为: 初次 检测到当前 eNB的资源使用率超出第一预设阈值; 或检测到当前 eNB的资源 使用率低于第二预设阈值。
上述方案中,所述检测当前 eNB的资源使用状态为实时或周期性检测当前 eNB的资源使用状态;
所述检测到当前 eNB的资源使用状态满足告警条件包括:相邻两次检测到 的当前 eNB的资源使用状态发生变化; 且检测到当前 eNB的资源使用率超出 第一预设阈值, 或检测到当前 eNB的资源使用率低于第二预设阈值。
上述方案中, 所述发送当前 eNB的资源使用状态通知信息, 包括但不限于 通过 RESOURCE STATUS UPDATE消息发送。
本发明实施例又提供了一种主动通知资源使用状态的装置,所述装置包括: 检测单元、 判定单元、 发送单元, 其中,
所述检测单元, 配置为检测当前 eNB的资源使用状态, 并将检测结果发送 给判定单元;
所述判定单元, 配置为根据接收到的当前 eNB的资源使用状态, 判定当前 eNB中的资源使用状态是否满足告警条件,并在判定当前 eNB中的资源使用状 态满足告警条件时, 触发发送单元;
所述发送单元, 配置为当前 eNB中的资源使用状态满足告警条件时, 发送 当前 eNB的资源使用状态通知信息。
上述方案中, 所述发送单元, 配置为向邻近 eNB发送当前 eNB的资源使 用状态通知信息。
上述方案中, 所述判定单元, 配置为初次检测到当前 eNB的资源使用率超 出第一预设阈值, 或检测到当前 eNB的资源使用率低于第二预设阈值时, 判定 当前 eNB中的资源使用状态满足告警条件。
上述方案中, 所述检测单元, 配置为实时或周期性检测当前 eNB的资源使 用状态; 相邻两次检测到的当前 eNB的资源使用状态发生变化; 且检测到当前 eNB的资源使用率超出第一预设阈值,或检测到 eNB的资源使用率低于第二预 设阈值时, 判定当前 eNB中的资源使用状态满足告警条件。
上述方案中, 所述装置还包括: 存储单元, 配置为存储检测到的当前 eNB 的资源使用状态信息、 以及所述第一预设阈值和第二预设阈值。
本发明实施例提供的主动通知资源状态的方法和装置,检测 eNB的资源使 用状态, 当检测到 eNB 的资源使用状态满足告警条件时, 主动向邻近的 eNB 发送资源状态信息; 邻近的 eNB收到所述资源状态信息后, 参考 eNB的资源 情况进行切换候选小区的筛选或优先级排序, 如此, 可降低 UE从邻近 eNB切 换到本 eNB的失败率, 并可优先保证本 eNB中 UE的接入成功率; 如果是多次 检测 eNB的资源使用状态, 那么, 当相邻两次检测到的资源使用状态相同时, 当前检测不再发送消息, 直到检测到的状态发生变化之后再发送, 这样, 能在 保证邻近 eNB准确获得本 eNB资源使用状态信息的情况下, 避免网络资源的 浪费。 附图说明

图 2为本发明实施例一主动通知资源使用状态方法流程示意图;
图 3为本发明实施例二主动通知资源使用状态具体实现方法流程示意图; 图 4为本发明实施例主动通知资源状态的装置结构示意图。 具体实施方式
本发明实施例的基本思想是: 检测当前 eNB的资源使用状态, 当检测到当 前 eNB的资源使用状态满足告警条件时, 则发送当前 eNB的资源使用状态通 知信息。
这里, 所述发送当前 eNB 的资源使用状态通知信息具体为: 向邻近 eNB 发送当前 eNB的资源使用状态通知信息。
这里, 所述检测当前 eNB的资源使用状态一般是检测多次, 可以是实时检 测, 也可以是周期性检测。
其中, 所述检测到当前 eNB的资源使用状态满足告警条件包括: 初次检测 到当前 eNB的资源使用率超出第一预设阈值, 或初次检测到当前 eNB的资源 使用率低于第二预设阈值; 或者, 检测到当前 eNB中的资源使用状态信息与上 一次检测到的当前 eNB的资源使用状态信息不一致, 且检测到当前 eNB的资 源使用状态超出第一预设阈值,或检测到当前 eNB的资源使用状态低于第二预 设阈值。
所述第一预设阈值和第二预设阈值可根据实际应用中的需求进行设定。 其中, 所述第一预设阈值为判定资源使用率高的阈值, 当实际资源使用率 超过第一预设阈值时, 即认为当前 eNB的资源使用率较高, 达到告警条件, 例 如, 当当前 eNB中资源使用率超过 80%时, 即认为达到告警条件; 所述第二预 设阈值为判定资源使用率低的阈值, 当实际资源使用率低于第二预设阈值时, 即认为当前 eNB的资源使用率较低 , 达到告警条件 , 例如, 当当前 eNB中资 源使用率低于 20%时, 即认为达到告警条件。 这里, 所述第一预设阈值应不小 于第二预设阈值。
所述邻近 eNB, 可以 居实际应用中所述当前 eNB周围的其他 eNB的位 置和交互关系进行确定, 可以为一个, 也可以为多个。
如图 1所示, 图 1为本发明实施例 eNB间发送资源状态消息示意图, 图 1 中, 当前 eNB有两个邻近 eNB: eNBl和 eNB2; 当检测到当前 eNB中资源使 用情况达到告警条件时, 即向邻近 eNB发送资源使用状态信息, 例如: 当检测 到当前 eNB 中资源使用率超过第一预设阈值, 即认为当前 eNB 中资源使用率 高, 达到告警条件, 则向邻近 eNB发送资源使用状态信息; 当检测到当前 eNB 中资源使用率低于第二预设阈值, 即认为当前 eNB中资源使用率低, 达到告警 条件, 则向邻近 eNB发送资源使用状态信息。
上述发送资源使用状态信息的步骤并不限定具体的执行顺序, 即: 当检测 到当前 eNB 中资源使用率高或资源使用率低时, 均向邻近 eNB发送相应的资 源使用状态信息; 当再次检测到当前 eNB的资源使用状态发生变化时, 例如, 上一次检测到资源使用状态为资源使用率高, 本次检测到的资源使用状态为资 源使用率低, 则再次向 eNB发送资源使用状态信息。
另外, 当上一次检测到资源使用状态处于资源使用率高 /低状态, 本次检测 到的资源使用状态仍然为资源使用率高 /低状态时 ,说明相邻两个次检测资源使 用状态没有发生变化, 则不向邻近的 eNB发送资源使用状态信息。
下面结合附图及具体实施例, 对本发明技术方案的实施作进一步的详细描 述。 图 2为本发明实施例一主动通知资源使用状态实现方法流程示意图, 如图 2所示, 本实施例主动通知资源使用状态的方法, 包括以下步骤:

对于初次检测而言,如果检测到当前 eNB的资源使用率超出第一预设阈值, 或检测到当前 eNB的资源使用率低于第二预设阈值, 则认为满足告警条件; 对于再次检测而言,如果本次检测到的当前 eNB的资源使用状态与上一次 检测到的当前 eNB的资源使用状态发生变化, 且检测到当前 eNB的资源使用 率超出第一预设阈值, 或检测到当前 eNB的资源使用率低于第二预设阈值, 则 认为满足告警条件。
例如, 当检测到当前 eNB中的资源使用率超出第一预设阈值, 且上一次检 测到的当前 eNB中的资源使用率低于第二预设阈值, 则判定当前 eNB 中的资 源使用状态满足告警条件, 执行步骤 203, 向邻近 eNB发送当前 eNB的资源使 用状态通知信息; 或者当检测到当前 eNB中的资源使用率超出第一预设阈值, 且上一次检测到的当前 eNB中的资源使用率也高于第一预设阈值,则判定当前 eNB中的资源使用状态不满足告警条件,返回执行步骤 201 ,继续检测当前 eNB 中资源使用状态信息。
步骤 203: 发送当前 eNB的资源使用状态通知信息;
这里, 所述发送当前 eNB 的资源使用状态通知信息具体为: 向邻近 eNB 发送当前 eNB的资源使用状态通知信息。
其中, 所述向邻近 eNB发送的资源使用状态通知信息可以是 RESOURCE STATUS UPDATE消息中的资源状态信息, 也可以是其它形式的指示资源状态 的信息;所述资源使用状态通知信息可以为资源使用率高或资源使用率低消息。
这里, 向邻近 eNB发送是向当前 eNB的所有邻近 eNB发送; 相应的, 各 个邻近 eNB收到此信息后, 会参考信息中的资源情况进行 UE切换候选小区的 筛选或优先级排序。
图 3为本发明实施例二主动通知资源使用状态具体方法流程示意图, 如图 3所示, 本实施例中, eNBl为当前 eNB, eNB2和 eNB3为 eNBl邻近 eNB, 当然, 在实际应用中, 还可以有更多邻近 eNB, 如邻近的 eNB4、 eNB5等等, 本实施例主动通知资源使用状态的方法, 包括以下步骤:
步骤 301: 初次检测 eNBl中资源使用状态;
具体的, 所述检测 eNBl的资源使用状态为: 检测当前 eNB的资源使用率 信息;
步骤 302: 判断 eNBl中的资源使用状态, 检测到 eNBl资源使用率高, 已 达到告警条件, 执行步骤 303;
其中, 所述检测到 eNBl资源使用率高, 具体为检测到 eNBl的资源使用 率超出第一预设阈值;
步骤 303: eNBl向邻近的 eNB 2和 eNB3发送资源使用状态信息; 其中, 所述向 eNB2 和 eNB3 和发送的资源使用状态通知信息可以是 RESOURCE STATUS UPDATE消息中的资源状态信息,也可以是其它形式的指 示资源状态的信息。
相应的, eNB2和 eNB3收到此资源使用状态通知信息后, 会参考此信息中 的资源情况进行 UE切换候选小区的筛选或优先级排序。
步骤 304: 继续检测 eNBl中资源使用状态信息;
具体的, 所述检测 eNBl的资源使用状态为: 检测当前 eNB的资源使用率 信息。
步骤 305: 判断 eNBl中的资源使用状态, 检测到 eNBl资源使用率低, 已 达到告警条件, 执行步骤 306;
其中, 所述检测到 eNBl资源使用率低具体为: 检测到 eNBl的资源使用 率低于第二预设阈值;
步骤 306: eNBl向邻近的 eNB 2和 eNB3发送资源使用状态信息; 其中, 所述向 eNB2 和 eNB3 和发送的资源使用状态通知信息可以是 RESOURCE STATUS UPDATE消息中的资源状态信息 ,也可以是其它形式的指 示资源状态的信息。
相应的, eNB2和 eNB3收到此资源使用状态通知信息后, 会参考此信息中 的资源情况进行 UE切换候选小区的筛选或优先级排序。
