本发明涉及通信领域, 特别涉及一种异构网络中提高寻呼接收可靠性的方法及 装置。 背景技术
在异构网络中, 可以通过布署小功率基站 (如 Pico基站)来提升系统容量或者扩 展系统覆盖范围。 如图 1所示为现有技术中 pico基站部署示意图, pico布署在宏基 站 (Macro) 覆盖范围内, 当 Macro小区负载较重时, Macro基站可以通过一定的参 数设置扩大 Pico基站的服务范围, 这部分扩大的 Pico服务范围称为小区边界扩展 (Cell Range Extension, CRE) , 即图 1中阴影部分, 通过增加 CRE, macro可以将 处于 CRE区域内的用户切换到 Pico基站内, 由 Pico基站为这部分用户提供服务, 从 而降低 Macro基站的负载。 以下, 由 Pico基站提供服务的 UE称 PUE, 由 Macro基站 提供服务的 UE称 MUE。
在长期演进(LTE)技术中, 寻呼消息可用于通知 UE其服务小区的系统信息是否 更新以及唤醒空闲态的用户进行下行数据的接收。基站在寻呼子帧发送寻呼消息, 寻 呼子帧的位置通过系统消息以广播方式告知小区覆盖范围内的 UE, 包括参数寻呼帧 的间隔 (nB)和寻呼周期 (T), 例如, 在 FDD系统中, 寻呼子帧配置可以如下表 1所 示:
表 1 : 现有基站寻呼子帧配置示意表
Figure imgf000003_0001
对于 UE来说, 考虑到 UE节能, UE不会每个寻呼子帧都去监听是否有寻呼, 而 是在特定子帧去监听, 该特定寻呼子帧通过下式计算得到:
i— s = floor (UE—ID/N) mod Ns
其中, N和 Ns通过 nB和 T得到,其中 Ν为(Τ, ηΒ)之中的最小值,即 min (Τ, nB), Ns为 (1, nB/T) 之中的最大值, UE— ID为 UE的标识信息。
举例来说, 当一个小区配置了其寻呼子帧为 Ns=2, 则该小区的寻呼子帧为子帧 4 和子帧 9; 进一步, 不同的 UE通过计算 i—s会到不同的寻呼子帧监听寻呼消息, 即 一部分 UE会到子帧 4监听寻呼, 而另一部分 UE会到子帧 9监听寻呼, UE会在每个 寻呼周期的寻呼子帧上去监听寻呼消息。 本发明的发明人发现现有技术中至少包括以下不足,小区的寻呼消息仅能在特定 的寻呼子帧发送, 如对 FDD系统来说, 仅能在子帧 0, 4, 5, 9发送寻呼; 在存在 CRE区 域的异构网络中, 若 Pico基站和 Macro基站都在这些子帧发送寻呼消息, 存在的强 干扰会导致 PUE无法正确接收寻呼消息。
应该注意, 上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、 完整的说明, 并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发 明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。 发明内容

如图 8所示为本发明实施例一种异构网络中提高寻呼接收可靠性方法的数据流 图。
包括 Pico基站 801, Macro基站 802, 0AM803。
首先步骤 901, Macro基站 802获取 Pico基站 801的小区寻呼配置信息, 具体可以如 图 9所示, 在该图中显示了 Macro基站 802可以通过多种方式获取 Pico小区的寻呼配置 信息, 在步骤 1001中由 Macro基站 802先请求 Pico基站 801发送该 Pico小区的寻呼配置 信息, 然后再由 Pico基站 801向 Macro基站 802发送该 Pico小区的寻呼配置信息; 或者 还可以如步骤 1002中, Pico基站可以直接将本小区的寻呼配置信息发送给 Macro基站 802, 其中, 寻呼配置信息可以包括但不限于背景技术中的参数寻呼帧的间隔 (nB) 、 Ns以及寻呼周期 (T) 中的一个或多个; 或者所述寻呼配置信息还可以是该 Pico小区 具体的寻呼子帧, 例如寻呼配置信息为子帧 9。 其中, Macro基站 802对 Pico小区寻呼 配置的获取可以通过 Pico基站 801与 Macro基站 802建立 X2接口时通过 X2 setup request消息或 X2 setup response消息传送; 或者可以通过 Pico基站 801向 Macro基站 802更新 Pico基站 801的配置信息时通过 eNB configuration update消息传送; 或者还 可以通过 Pico基站 801向 Macro基站 802请求 ABS子帧配置时通过负载信息 (load information) 消息传送; 或者还可以通过定义新的 X2接口消息来传送。
在该步骤中, Macro基站 802还可以通过网络管理与维护实体(0AM) 803获取相应 Pico小区的寻呼配置信息, 如图 10所示, 如步骤 1101中, Macro基站 802可以通过主动 向 0AM803请求相应 Pico小区的寻呼配置信息,例如在发送微小区寻呼配置请求的同时 还可以包括该微小区的标识, 然后 0AM803再将请求的 Pico小区的寻呼配置信息(还可 以包括微小区标识)发送给 Macro基站 802; 或者如步骤 1102中, 0AM803还可以直接将 相应 Pico小区的寻呼配置信息发送给 Macro基站 802。
通过上述的步骤, Macro基站 802就可以获知 Pico小区的寻呼配置信息。
其次在步骤 902中, Pico基站 801通过负载信息 (load information) 向 Macro基 站 802请求 ABS子帧分配。
再次在步骤 903中, Macro基站 802得知了 Pico基站所使用的寻呼子帧, 则根据所 述 Pico基站的寻呼配置信息进行 ABS子帧配置。
例如假设 Pico小区寻呼配置所指示的寻呼子帧为子帧 9, Macro小区的寻呼子帧为 子帧 0, 4, 5, 9; 则 Macro基站 802可以知道仅在子帧 9上的寻呼消息会有干扰; Macro基 站 802将子帧 9设置为 ABS子帧, Macro基站 802可以选择将子帧 0, 4, 5设置为非 ABS子帧。
再次在步骤 904中, Macro基站 802将 ABS子帧配置信息通过负载信息 (load information) 发送给 Pico基站。
最后步骤 905中, Macro基站 802在 Pico小区寻呼配置所指示的子帧以外的其他寻 呼子帧上正常发送寻呼消息, 而在 Pico小区寻呼配置所指示的子帧上进行选择性发 送。 Pico基站 801在本小区的寻呼子帧正常发送寻呼消息。
例如, 如图 11所示为本发明实施例寻呼消息发送示意图, 当发送寻呼时, Macro 基站 802在寻呼子帧 0, 4, 5上正常发送寻呼消息, 而在寻呼子帧 9上 Macro基站 802 可以选择在某些寻呼周期的寻呼子帧 9正常发送寻呼消息 (如图 11中寻呼周期湖的 无线帧 # (N, 1)的寻呼子帧 9;寻呼周期# (^1)的无线帧# (^1, 0)的寻呼子帧 9;其中, 无线帧 # (N, 1)表示第 N个寻呼周期的 #1无线帧, 其余类似), 以保证 Macro小区覆 盖范围内的 MUE对寻呼信息接收的可靠性;而在另外一些寻呼周期的寻呼子帧 9上 (如 图 11 中的寻呼周期 的无线帧# ( 0)的寻呼子帧 9; 寻呼周期# (^1)的无线帧 # (N+1, 1)的寻呼子帧 9), Macro基站 802不发送寻呼消息或者降低功率发送寻呼消息, 上述的寻呼周期湖和其相邻的寻呼周期 # (N+1)只是举例说明, Macro基站 802也可以 在寻呼周期 # (N+2)无线帧 # (N+2, 1)的寻呼子帧 9 (图未示) 不发送寻呼消息或者降低 功率发送寻呼消息。 Pico基站在其寻呼子帧 9上正常发送寻呼消息。
作为本发明的实施例,寻呼消息发送示意图还可以如图 12所示,在本例中, Pico 小区的寻呼子帧配置包含 Macro小区的寻呼子帧配置,假设 Macro寻呼子帧为子帧 9, Pico小区的寻呼子帧为子帧 0、 4、 5、 9, Macro基站 802进行 ABS子帧配置时将子 帧 0、 4、 5、 9配置为 ABS子帧, Pico基站 801可以在子帧 0、 4、 5、 9发送寻呼消 息, 而 Macro基站 802在寻呼周期湖无线帧 # (N, 0)的子帧 9不发送寻呼消息或者降 低功率发送寻呼消息,在寻呼周期 # (N+1)的无线帧# (^1, 0)的子帧 9正常发送寻呼消 息, 这样虽然在寻呼周期 # (N+1)无线帧 # (N+1, 0)的子帧 9会对 Pico基站的 CRE区域 中的 PUE造成一定干扰, 但是 Pico基站通过在下一个寻呼周期或者后面的某个寻呼 周期的相应子帧中发送寻呼消息,因此可以减轻对 Pico小区中 PUE的寻呼接收干扰, 并且尽可能保证 Macro小区内 MUE的寻呼消息的可靠接收。 实施例八
