本发明实施例提供的通信方法和通信设备具体可以应用于通信系统中用 户设备 UE与第一网络已经建立无线资源控制协议 (Radio Resource Control , 以下简称 RRC)连接, 并处于 RRC激活态, 即 UE与该第一网络进行数据传输时, UE离开该第一网络去监听第二网络的寻呼信息时, 对 UE停止调度数据处理的 过程, 其中第一网络与第二网络为不同制式下的网络, 如, 第一网络为 LTE 网络, 第二网络为 CDMA网络。 本实施例提供的通信方法具体可以通过通信装 置来执行, 该通信装置可以集成在基站中, 该通信装置可以采用软件和 /或硬 件的方式来实现。 以下以第一网络为 LTE网络, 第二网络为 CDMA网络为例, 对 本发明实施例进行详细地说明。
图 1为本发明通信方法一个实施例的流程图。 如图 1所示, 本实施例提 供的通信方法具体包括如下:
步骤 101、 基站获取 UE监听其他网络寻呼信息的开始时刻。 需要说明的是, UE在开始时刻之前所在网络的网络制式与上述的其他网 络的网络制式不同,该开始时刻可以为 UE开始监听其他网络寻呼信息的开始 时隙。
举例来讲, UE可以周期性的离开基站提供的 LTE 网络, 而去监听 CDMA 网络寻呼信息, 其中, 该 CDMA网络可以是提供 LTE网络的基站, 也可以是其 他基站提供的。具体的, 所述 UE在开始时刻之前的第一特定时长内所在的网 络制式与所述 UE 开始时刻之后的第二特定时长内所在的网络制式不同, 其 中, 第一特定时长与第二特定时长可以通过基站人为配置, 例如, UE周期性 接入 LTE网络的时长为第一特定时长, UE周期性接入 CDMA网络即监听 CDMA 网络的时长为第二特定时长。
在本实施例中,基站获取 UE监听其他网络寻呼信息的开始时刻至少有三 种实现方式, 可以包括:
第一种实现方式, 基站获取 UE的帧偏置, 接着, 基站根据该帧偏置, 获 取 UE监听其他网络寻呼信息的开始时刻。
第二种实现方式, 在一定时长和 /或预设次数内, 基站没有接收到 UE发 送的信息, 则基站确定 UE在监听其他网络寻呼信息, 并将确定 UE在监听其 他网络寻呼信息的时间作为 UE本次监听其他网络寻呼信息的开始时刻。
第三种实现方式,基站根据 UE上一次监听该其他网络寻呼信息的时间或 UE上一次监听该其他网络寻呼信息之后返回的时间, 获取 UE本次监听其他 网络寻呼信息的开始时刻。
具体的, 在第一种实现方式中, 基站获取 UE的帧偏置的实现场景至少有 3种, 包括:
第一实现场景, 基站从移动性管理实体 (Mobility Management Entity, 以下简称匪 E) 获取 UE的帧偏置, 例如, UE与基站建立 RRC连接的情况下, 基站可以接收 MME发送的初始上下文更新请求消息, 其中, 该初始上下文更 新请求消息携带帧偏置。 或者, 基站向匪 E发送帧偏置请求消息, 该帧偏置 请求消息用以请求 UE的帧偏置,接着,基站接收匪 E发送的帧偏置应答消息, 其中, 该帧偏置应答消息携带帧偏置。 需要说明的是, 该帧偏置可以是匪 E 根据终端国际移动用户识别码 ( International Mobile Subscriber Identification Number, 以下简称 IMSI ) 计算获取的。 第二实现场景, 基站从 CDMA-LTE 互操作功能实体 ( Interworking solution Function , 以下简称 IWS ) 获取 UE的帧偏置, 例如, UE与基站建 立 RRC连接的情况下, 基站向 IWS发送请求 UE的帧偏置的信息, 接着, 基 站接收 IWS发送的帧偏置。需要说明的是, 该帧偏置可以是 IWS根据 IMSI计 算获取的。
第三实现场景, 基站从 UE自身获取 UE的帧偏置, 例如, UE与基站建立 RRC 连接的情况下, 基站接收 UE发送的 RRC连接更新消息, 其中, 该 RRC连 接更新消息携带有 UE的帧偏置参数; 或者, 基站接收 UE发送的寻呼帧偏置 应答消息,该寻呼帧偏置应答消息是基站向 UE发送寻呼帧偏置请求消息之后 基站接收的,其中,该寻呼帧偏置应答消息携带 UE的帧偏置。需要说明的是, 该帧偏置可以是 UE根据 IMSI计算获取的。
相应的, 不论是上述的哪种实现场景, 基站可以根据该帧偏置、 寻呼周 期, 获取 UE监听其他网络寻呼信息的开始时刻。
举例来讲, 基站可以根据是否配置 QPCH信道, 确定 UE是否在快速寻呼 信道监听其他网络寻呼信息, 其中, 该配置 QPCH信道的信息可以是通过人工 静态的配置在基站上的, 若基站确定配置有 QPCH信道, 则确定 UE在快速寻 呼信道监听其他网络寻呼信息, 运用公式 (2 ), 或者, 若基站确定没有配置 QPCH信道, 则确定 UE在寻呼信道监听其他网络寻呼信息, 运用公式 (1 ), 从而根据公式 (1 ) 或公式 (2 ) 获取 UE监听其他网络寻呼信息的开始时刻。
(T/4 -帧偏置) mod (寻呼周期) = 0 公式 (1 ), 其中:
