一种负荷信息传递方法、 系统、 网元及计算 储介质 技术领域
本发明涉及无线接入技术领域, 具体涉及一种负荷信息传递方法、 系 统、 网元及计算机存储介质。 背景技术

本发明实施例中, 第一网元根据第二网元的请求或者第一网元主动将 自身的负荷信息发送给第二网元。
下面通过附图及具体实施例对本发明 #丈进一步的详细说明。 实施例一
本发明实施例一提供了一种负荷信息传递方法, 图 1 为本发明至少一 个实施例提供的负荷信息传递方法流程图一, 如图 1 所示, 所述方法包括 以下步骤:
步骤 101 : 第一网元获取自身的负荷信息。
步骤 102:第一网元根据第二网元的请求将自身的负荷信息发送给第二 网元, 或者第一网元主动将自身的负荷信息发送给第二网元; 其中, 当所 述第一网元为 WLAN网元时, 所述第二网元为 3GPP网元; 当所述第一网 元为 3GPP网元时, 所述第二网元为 WLAN网元。
本发明实施例中的第一网元和第二网元是指两种不同无线接入技术标 准下的网元, 例如: 第一网元可以是 WLAN网元, 具体的, 可以指接入点 ( AP, Access Point )、 接入控制器 (AC, Access Controller ), 或者也可以 是独立设备单元; 第二网元可以是 3GPP网元, 更具体的, 可以是 LTE系 统下的演进基站 (eNB, evolved Node B )、 通用移动通信系统(UMTS, Universal Mobile Telecommunications System ) 下的无线网络控制器( RNC, Radio Network Controller ), 全球移动通信系统( GSM, Global System for Mobile Communications ) 下的基站控制器( BSC, Base Station Controller ), 或者也可以是独立设备单元; 当然, 反过来, 第一网元是 3GPP网元, 第二 网元是 WLAN网元也是可以的;
具体的, 这里的负荷信息是指能够反映第一网元所在网络的系统负荷 情况的信息, 例如, 对于 3GPP网元来说, 在 LTE系统下, 所述负荷信息 可以是 LTE小区的总体可用资源水平, 包括下行总体可用资源水平和上行 总体可用资源水平, 这里所说的总体可用资源水平通过小区容量等级值或 容量值来表示;在 UMTS陆地无线接入网( UTRAN, UMTS Terrestrial Radio
Access Network ) 系统下, 所述负荷信息可以是 UTRAN小区的负荷水平, 包括上行负荷水平和下行负荷水平, 这里所说的负荷水平可以由小区容量 等级值、 负荷值、 实时业务负荷值或非实时业务负荷值来表示; 在 GSM系 统下, 所述负荷水平可以是 GSM小区的负荷水平, 包括上行负荷水平和下 行负荷水平, 这里所说的负荷水平可以由小区容量等级值、 负荷值、 实时 业务负荷值或非实时业务负荷值来表示; 具体的, 所述第一网元可以实时 获取其所连接的各接入网设备的负荷信息, 并将所述负荷信息保存于本地, 当接入网设备的负荷信息发生变化时, 第一网元能够动态更新本地保存的 负荷信息; 这里, 仅给出负荷信息获取的一种实现方式, 在实际操作中, 还可以釆用其他各种方式进行负荷信息的获取, 这里不做限制。
通常, 在 WLAN中, 接入网设备 AP的负荷信息可以通过以下信息中 的至少一种信息来表示: STA个数、 信道利用率、 可接入能力; 其中, 所 述 STA个数是指当前连接到基本服务集( BSS, Basic Service Set )上的 STA 个数; 所述信道利用率是指信道繁忙时间的百分比; 所述可接入能力是指 剩余可接入时间, 所述可接入能力信息可用于 STA选择合适的 AP进行接 纳尝试以保证 QoS需求。
然而, 在 WLAN系统中, 目前还没有定义合适的跨系统交互使用的负 荷信息; 因此, 本发明实施例中定义了新的用于 WLAN实现跨系统交互的 负荷信息。 具体的, 使用总体资源可用水平和 /或负荷水平指示信息来表示 WLAN系统负荷信息; 其中, 所述总体资源可用水平用资源可用百分比来 表示; 所述负荷水平指示信息可以用重过载指示信息、 过载指示信息或轻 载指示信息来表示。 当仅用于 WLAN系统负荷信息的粗略估计时, 可以使 用总体资源可用水平或负荷水平指示信息作为负荷信息; 当用于对 WLAN 系统的负荷信息进行精确估计时, 所述第一网元可以将总体资源可用水平 和负荷水平指示信息同时作为负荷信息发送给所述第二网元。
具体的, 在这一步骤中, 第一网元能够通过两种机制将自身的负荷信 息发送给第二网元; 一种是请求 -响应机制, 另一种是直接通知机制。
下面通过具体示例, 对本发明实施例一提供的负荷信息传递方法作以 下详细说明。
示例一

所述负荷信息响应消息构造完成之后, 所述第一网元根据所述负荷信 息请求消息中的请求类型将所述负荷信息响应消息发送给所述第二网元。 具体的, 若所述负荷信息请求消息中的请求类型为周期触发类型, 则所述 第一网元按照所述第二网元请求的周期实时更新接入网设备的负荷信息, 并将最新的接入网设备的负荷信息发送给所述第二网元; 若所述负荷信息 请求消息中的请求类型为事件触发类型, 则当所述第二网元所请求的事件 发生时, 所述第一网元实时更新接入网设备的负荷信息, 将所有负荷信息 以列表的方式下发至所述第二网元; 当所述第二网元发送的接入网设备信 息中包含多个接入网设备标识时, 所述第一网元将所述多个接入网设备标 识对应的多个接入网设备的负荷信息以列表形式下发给所述第二网元。
否则, 如果所述第一网元的本地操作失败, 不能正常反馈所述第二网 元所请求的负荷信息, 则转至步骤 204执行。
步骤 203: 第二网元接收到负荷信息响应消息后, 保存所述负荷信息响 应消息中的负荷信息。
所述负荷信息可用于后续所述第一网元和所述第二网元之间网络资源 的优化管理或网络连接策略优化。 比如, 当根据得到的负荷信息得知所述 第一网元负荷过重时, 则在空口下发给用户终端可选第一网元测量列表的 时候, 进行列表优化, 或者提高用户终端切换到所述第一网元的信号质量 测量门限; 结束当前流程。
步骤 204: 当所述第一网元构造负荷信息响应消息失败时, 向所述第二 网元返回构造负荷信息失败消息, 所述构造负荷信息失败消息中包括在不 同请求类型下的失败原因。
这里, 所述构造负荷信息失败的原因可以有多种, 例如, 由于网络异 常、 内存溢出、 读写异常等原因引起的负荷信息不能成功获取或获取的负 荷信息不正确等。
