一种实现负荷报告的方法及接入网网元
技术领域

当 LTE小区负荷比较高, 希望分流部分负荷到相邻的 UMTS小区时, 该 LTE小区所在 eNB需要向该 UMTS邻区所在 RNC发送负荷报告请求消息以 单次或多次获取该 UMTS邻区的负荷信息, 然后根据获得的邻区的负荷信息 决定其负荷分流策略。 一般 LTE小区的覆盖面积较小, UMTS小区的覆盖面 积较大; 而一个 RNC保存有很多 UMTS小区的负荷信息; 因此, 一般距离 较近的 LTE小区的 UMTS邻区的负荷信息都保存在同一个 RNC;当这些 LTE 小区所在 eNB需要了解其 UMTS邻区的负荷信息时, 一般都向同一个 RNC 发送负荷才艮告请求消息。
当在一段比较短的时间内 (如, 几秒钟) , 有多个 eNB需要了解同一个 UMTS邻区的负荷信息时, RNC如果给每个发负荷报告请求消息的 eNB回负 荷报告响应消息, 将会造成系统间负荷报告响应消息太多 (如图 2 ) , 尤其 对于多负荷才艮告请求而言。
因此, 如何优化 GSM/EDGE、 UMTS, LTE等系统间的负荷信息报告机 制, 以减少系统间的消息交互是本发明实施例所要描述的内容。 发明内容 本发明实施例要解决的技术问题是提供一种实现系统间负荷信息报告的 方法、 装置和系统, 以解决负荷报告响应消息过多的问题。

在实际应用中, 当 LTE小区负荷比较高时, 希望分流部分负荷到相邻的 UMTS小区时,该 LTE小区所在的 eNB需要向该 UMTS邻区所在 RNC发送 负荷报告请求消息以请求单次获取该 UMTS邻区的负荷消息, 然后根据获得 的邻区的负荷信息决定其负荷分流策略。
当 RNC在一段预定的时间内, 如预先设定 3秒, 收到来自 5个演进型基 站的负荷报告请求消息时, 即有 5个演进型基站, 分别将其命名为 1号演进 型基站, 2号演进型基站, 3号演进型基站, 4号演进型基站和 5号演进型基 站。 该实施例中, 5个演进型基站(eNB )的负荷报告请求消息所要获取的是 同一个 UMTS邻区的负荷信息,或所对应的 UMTS小区为邻区或在距离上很 接近。

以下结合应用实例和附图对本发明作详细描述。
结合图 1 , 以下各应用实例的初始场景如下:
小区 (Cell ) 1、 Cell2属于 eNBl , Cell3属于 eNB2, Cell4、 Cell5属于 eNB3; eNBl , eNB2、 eNB3连接到 LTE CN。 Cell A属于 Node Bl , Cell B 属于 Node B2; Node Bl、 Node B2连接到 RNC1; RNC1连接到 UMTS CN。
应用实例一
该应用实例中, eNB 1、 eNB 2作为请求发送方, RNC 1作为请求接收方, 目标基站代表从 M个请求发送方中选取 N个请求发送方的意思,非目标基站 代表 N个请求发送方之外的请求发送方的意思(即 M减去 N后剩余的请求 方请求发送方的个数) 。 结合图 1、 图 8的应用实例描述如下:

目标基站 eNBl收到 RNC1的负荷报告响应消息后, 发现消息中携带有 转发列表包括非目标基站 eNB2、 eNB3的标识, 于是通过 X2接口将负荷报 告响应消息转发到非目标基站 eNB2、 eNB3。
eNBl , eNB2、 eNB3根据获得的邻区的负荷信息, 决定其负荷分流策略。
应用实例二
该应用实例中, eNB 1、 eNB 2、 eNB 3作为请求发送方, RNC1作为请 求接收方, 结合图 1、 图 9的应用实例描述如下:

在一预定时间内, 如 1至 3秒内, RNC1收到 eNBl、 eNB2、 eNB3的负 荷报告请求消息, 为了尽量减少系统间消息 (UMTS CN和 LTE CN间) , RNC1将 eNBl作为目标基站, 即 RNC1将负荷报告响应消息发送到 eNBl , 消息中携带 Cell A和 Cell B的负荷信息,并在消息中携带转发列表包括 eNB2、 eNB3的标识;负荷报告响应消息经由 UMTS CN、LTE CN发送至 eNBl ; RNC1 根据负荷报告请求消息中的要求(比如负荷变化量大于一定值, 或每隔一定 的时间间隔) , 多次向 eNBl发送上述负荷报告响应消息, 直到收到负荷报 告停止消息。
目标基站 eNBl收到 RNC1的负荷报告响应消息后, 发现消息中携带有 转发列表包括非目标基站 eNB2、 eNB3的标识, 于是通过 X2接口将负荷报 告响应消息转发到非 eNB2、 eNB3。
eNBl , eNB2、 eNB3根据获得的邻区的负荷信息, 决定其负荷分流策略。
应用实例三
该应用实例中, eNB 1、 eNB 2作为请求发送方, RNC1作为请求接收方, 结合图 1、 图 10的应用实例描述如下:
Cell 1、 Cell 3负荷比较高, eNBl向 RNC1发送负荷报告请求消息以多次 获取 Cell 1的邻区 Cell A的负荷信息, eNB2向 RNC1发送负荷报告请求消息 以多次获取 Cell 3的邻区 Cell A和 Cell B的负荷信息; 负荷才艮告请求消息经 由 LTE CN、 UMTS CN发送至 RNC1。
在一预定时间内, RNC1收到 eNBl、 eNB2的负荷报告请求消息, 为了 尽量减少系统间消息( UMTS CN和 LTE CN间 ) , RNC1只将负荷报告响应 消息发送到目标基站 eNB 1 ,消息中携带 Cell A和 Cell B的负荷信息,并在消 息中携带转发列表包括 eNB2的标识;负荷报告响应消息经由 UMTS CN、LTE CN发送至 eNBl; RNC1根据负荷报告请求消息中的要求(比如负荷变化量 大于一定值, 或每隔一定的时间间隔) , 多次向 eNBl发送上述负荷 4艮告响 应消息, 直到收到负荷才艮告停止消息。
目标基站 eNBl收到 RNC1的负荷报告响应消息后, 发现消息中携带有 转发列表包括 eNB2的标识, 于是通过 X2接口将负荷报告响应消息转发到 eNB2。
Cell 4负荷比较高, eNB3向 RNC 1发送负荷报告请求消息以多次获取 Cell 4的邻区 Cell B的负荷信息; 负荷报告请求消息经由 LTE CN、 UMTS CN发 送至 RNC1。
RNC1收到 eNB3的负荷报告请求消息,为了尽量减少系统间消息( UMTS CN和 LTE CN间) , RNC1只将负荷报告响应消息发送到 eNBl , 消息中携 带 Cell A和 Cell B的负荷信息, 并在消息中携带转发列表包括 eNB2、 eNB3 的标识; 负荷报告响应消息经由 UMTS CN、 LTE CN发送至 eNBl ; RNC1 根据负荷报告请求消息中的要求(比如负荷变化量大于一定值, 或每隔一定 的时间间隔) , 多次向 eNBl发送上述负荷报告响应消息, 直到收到负荷报 告停止消息。其中负荷量大于一定值,是指 Cell A或 Cell B的负荷量的大小。
eNBl收到 RNC1的负荷报告响应消息后,发现消息中携带有转发列表包 括 eNB2、 eNB3的标识,于是通过 X2接口将负荷报告响应消息转发到 eNB2、 eNB3。
eNBl , eNB2、 eNB3根据获得的邻区的负荷信息, 决定其负荷分流策略。
应用实例四
结合图 1、 图 11的应用实例描述如下:
Cell 1 , Cell 3、 Cell 4负荷比较高, eNBl向 RNC1发送负荷报告请求消 息以获取 Cell 1的邻区 Cell A的负荷信息, eNB2向 RNC1发送负荷报告请求 消息以获取 Cell 3的邻区 Cell A和 Cell B的负荷信息, eNB3向 RNC1发送负 荷才艮告请求消息以获取 Cell 4的邻区 Cell B的负荷信息; 负荷才艮告请求消息 经由 LTE CN、 UMTS CN发送至 RNC1。
RNC1在一段较短时间内 (如几秒钟)收到 eNBl、 eNB2、 eNB3的负荷 报告请求消息, 为了尽量减少系统间消息(UMTS CN和 LTE CN间),RNC1 只将负荷才艮告响应消息发送到 eNBl ,消息中携带 Cell A和 Cell B的负荷信息, 并在消息中携带转发列表包括 eNB2、 eNB3的标识; 负荷报告响应消息经由 UMTS CN, LTE CN发送至 eNBl。
eNBl收到 RNC1的负荷报告响应消息后,发现消息中携带有转发列表包 括 eNB2、 eNB3的标识, 但在 eNBl与 eNB2、 eNBl与 eNB3之间没有 X2 接口, 于是通过 S1接口经由 LTE CN将负荷报告响应消息转发到 eNB2、 eNB3。
eNBl、 eNB2、 eNB3根据获得的邻区的负荷信息, 决定其负荷分流策略。 综上所述可见, 本发明实施例的实现负荷报告的技术可以在减少负荷报 告响应消息的情况下, 实现负荷均衡。
