本发明涉及移动通信设备领域， 尤其涉及导频信号状态提示方法、基站控 制器及移动交换中心。 背景技术
在 CDMA ( Code Division Multiple Access, 码分多址） 网络中， 当两个移 动终端用户 A和 B在建立通话后，他们的网络拓朴结构简化模型如图 1所示， 包括 A用户对应的基站系统 BS1、移动交换中心 MSC1 , B用户对应的基站系 统 BS1、移动交换中心 MSC2。 其中 BS是 CDMA网络的无线收发设备， 主要 与移动终端进行无线通讯。 MS要负责移动用户话务管理。
在终端用户通话状态下， 终端会上报当前检测的导频强度给 BS, 当终端 用户处于信号较强的无线环境中时， 则上报的导频强度值越大， 反之越弱。 因 此， BS能够实时监测到终端导频强度， 从而根据导频强度值的大小判断终端 用户所处的无线环境信号的强弱。
当终端用户 A处在的环境信号越差， BS1检测到的导频强度的值越小， 当 小到一定程度后， A用户将有可能出现通话断续， 通话无声音等异常现象， 由 于 A用户的异常， B用户也将会出现通话异常现象，比如对 A用户讲了许多句话， 但是听不到 A用户的回应， 严重影响了通信质量， 降低了用户体验。 发明内容 有鉴于此， 本发明提供一种导频信号状态提示方法、基站控制器及移动交 换中心。 其具体方案如下：

提示信息发送模块， 用于依据所述提示信令， 向所述通话状态下的对端终 端发送表征所述第一终端导频信号状态差的提示信息。
从上述的技术方案可以看出， 本发明实施例公开的导频信号状态提示方 法，基站控制器通过对第一终端上报的导频强度进行检测， 当导频强度小于预 设门限值时， 向对端对应的移动交换中心发送提示命令，使得该交换中心依据 提示命令向对端发送提示信息，从而使得对端可以及时获得第一终端的导频信 号状态情况， 保证了通话的质量， 提高了用户体验。 附图说明

图 2为本发明实施例公开的导频信号状态提示方法的流程图；
图 3为本发明实施例公开的又一导频信号状态提示方法的流程图； 图 4为本发明实施例公开的又一导频信号状态提示方法的流程图； 图 5为本发明实施例公开的基站控制器的结构示意图；
图 6为本发明实施例公开的移动交换中心的结构示意图。 具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是 全部的实施例。基于本发明中的实施例， 本领域普通技术人员在没有做出创造 性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
本发明公开了导频信号状态提示方法， 应用于 CDMA网络， 可以实现当 通话过程中，一方终端的信号质量差的情况下，对端终端可以及时获知的目的， 提高了用户体验。
本发明公开的一种导频信号状态提示方法的流程图如图 2所示， 包括： 步骤 S21、 接收通话状态下的第一终端上报的导频强度；
步骤 S22、 当导频强度小于预设门限值时， 向通话状态下的对端终端对应 的移动交换中心发送提示信令， 对端终端对应的移动交换中心依据提示信令， 向对端终端发送表征第一终端导频信号状态差的提示信息。
进一步的， 当导频强度不小于预设门限值时， 不釆取任何操作。
进一步的， 当通话双方的终端处于同一移动交换中心时， 向通话状态下的 对端终端对应的移动交换中心发送提示信令的过程为：基站控制器向第一终端 和对端终端对应的移动交换中心发送提示信令，从而通过该移动交换中心， 向 对端终端发送提示信息。
而当通话双方的终端处于不同移动交换中心时，向通话状态下的对端终端 对应的移动交换中心发送提示信令的过程包括：
向第一终端对应的移动交换中心发送提示信令；
第一终端对应的移动交换中心将提示信令发送给对端终端对应的移动交 换中心。
最终通过对端终端对应的移动交换中心向对端终端发送提示信息，该提示 信息可以为语音提示信息，即对端终端对应的移动交换中心向对端终端发送语 音信息， 该语音信息的主要内容为第一终端的导频信号状态差， 例如 "友情提 醒： 当前和您通话的用户信号差， 有可能通话异常"。 或者向对端终端发送文 字信息， 例如短信息， 该短信息的主要内容为第一终端的导频信号状态差。 从 实际应用场景考虑， 进行通话的用户通常无法及时查收收到的短信息， 所以， 釆用发送短信息的方式有可能使对端终端用户在结束通话后才能得知第一终 端的导频信号状态差， 与语音提示的方式相比， 其时效性较差。 同样， 也可以 釆用同时发送语音提示信息和文字信息的方式。文字信息除包含短信息外，还 可包括彩信或者邮件。
本实施例公开的导频信号状态提示方法，基站控制器接收第一终端上报的 导频强度并进行检测， 当导频强度小于预设门限值时， 向对端对应的移动交换 中心发送提示命令， 使得该移动交换中心依据提示命令向对端发送提示信息， 从而使得对端可以及时获得第一终端的导频信号状态情况，及时了解当前无法 进行正常通话的原因， 保证了通话的质量， 提高了用户体验。 本发明公开的又一导频信号状态提示方法的流程如图 3所示， 包括： 步骤 S31、 基站控制器接收通话状态下的第一终端上报的导频强度； 步骤 S22、 判断导频强度是否小于预设门限值， 若是， 则执行步骤 S23 , 若否， 则结束；
本实施例中的预设门限值 MIN PILOT为 -28dbm, 还可以为 -30bm或其他 根据实际网络条件动态设定的值。
步骤 S33、 向对端终端对应的移动交换中心发送提示信令， 该提示信令为 预留比特位为预设值的 A接口信令；
本实施例中， 可以釆用将 A接口信令的预留比特位按照预设规则赋值为 预设值的方式， 得到提示信令， 具体的赋值方式可以为： 将基站控制器与移动 交换中心之间的 A接口信令中的预留比特位置 1 ;
本实施例中， 通过对应用于基站控制器和移动交换中心间的 A接口信令 进行扩展， 利用扩展后的 A接口信令发送提示信令， 一般来说， 扩展是将原 有规则中具有预留位的比特上赋予新的功能，所以通常的扩展方式为利用空闲 比特位， 或是复用其他功能的比特位。 本实施例釆用设置空闲比特位的方式， 根据预设规则将预留空闲比特位全部置 1 , 以此表示当前发送的信令为提示信 令。
步骤 S34、 对端终端对应的移动交换中心依据提示信令， 向对端终端发送 表征第一终端导频信号状态差的语音提示信息。
本实施例并不限定釆用将预留空闲比特位全部置 1的方式进行信令扩展， 具体的扩展方案可以根据不同的情况进行设定， 例如，在将特定的预留比特位 置 1 , 只要保证对端终端对应的移动交换中心能够识别扩展后的信令为提示信 令即可。
本实施例公开的导频信号状态提示方法，通过对基站控制器和移动交换中 心间的信令进行扩展得到提示信令，使得该方法以现有信令作为载体， 利用现 有的信令传输模式， 实现提示信令的传输， 操作简单， 易于实现。 本发明同时公开的又一导频信号状态提示方法的流程如图 4所示， 包括： 步骤 S41、 接收提示信令， 该提示信令为通话状态下的第一终端上报的导 频强度小于预设门限值时，第一终端对应的基站控制器向所述通话状态下的对 端终端对应的移动交换中心发送的；
步骤 S42、 依据提示信令， 向通话状态下的对端终端发送表征第一终端导 频信号状态差的提示信息。
本实施例公开的方法应用于第一终端对应的移动交换中心， 与图 2或图 3 所示的方法对应， 最终实现将提示信息发送到对端终端上，使对端终端能够及 时获得第一终端的导频信号状态的目的。当通话双方的终端处于同一移动交换 中心时， 还应用于第一终端和对端终端共同对应的移动交换中心。
本实施例中的提示信息可以为语音提示信息、文字提示信息或者同时发送 语音和文字提示信息。文字提示信息除包含短信息外，还可包括彩信或者邮件。 语音提示信息和文字提示信息的内容并不限定，只要能够使对端终端可以获知 到第一终端的导频信号状态的内容都是本实施例保护的范围。 本发明同时公开了一种基站控制器， 其结构如图 5所示， 包括： 导频强度 接收模块 51和提示信令发送模块 52 , 其中：
导频强度接收模块 51用于接收通话状态下的第一终端上报的导频强度； 提示信令发送模块 52用于当导频强度小于预设门限值时， 向通话状态下的对 端终端对应的移动交换中心发送提示信令，对端终端对应的移动交换中心依据 提示信令， 向对端终端发送表征所述第一终端导频导频信号状态差的提示信 息。 提示信令为预留比特位为预设值的 A接口信令， A接口信令的预留比特 位赋值为预设值的方法与前述实施例相同， 在此不再详述。 本发明同时公开了一种移动交换中心， 其结构如图 6所示， 包括： 提示信 令接收模块 61和提示信息发送模块 62 , 其中，
