Description

等待通知方法^ ^站控制器 技术领域 本发明涉及通信领域,具体而言, 涉及一种等待通知方法及基站控制器。 背景技术 无线优先接入月艮务是一种可以为经过合法 ·ί受权的机构和用户提供优先接 入无线网络的服务, 其特点在于当网络的资源 (包括无线资源和地面电路资 源)不足时, 这些经过合法授权的机构和用户若发起无线优先接入语音呼叫, 网络侧不会因为资源不足而让呼叫失败, 而是将该呼叫按优先级排队, 一旦 有可用资源马上将资源分配给该呼叫, 让呼叫成功, 从而达到提供优先接入 业务的目的。 无线优先接入业务在发生紧急状况时会经常被用到。 无线优先接入服务的主要特性为: 无线优先接入服务只提供给经过合法授权的机构和用户使用, 且用户需 要事先签约, 获取许可; 用户通过在拨号号码前增加特殊前缀来获得无线优先接入服务, 也就是 说该服务是针对单个呼叫的, 而不是针对用户的; 用户使用无线优先接入服务时, 如果系统资源拥塞, 系统将该呼叫进行 排队 (不抢占其他用户), 最长排队时间可根据实际应用场景设置。 发明人发现上述的相关技术中,在用户排队的过程中不给用户任何提示, 这样一来, 按用户的一般习惯很有可能会以为系统异常, 进而结束呼叫, 造 成无线优先接入呼叫建立失败。 发明内容 本发明的主要目的在于提供一种等待通知方法及基站控制器, 以至少解 决上述问题之一。 根据本发明的一个方面, 提供了一种应用于无线优先接入呼叫的等待通 知方法, 包括: 基站控制器接收基站收发器发送的基本信道建立失败消息及 移动交换子系统发送的指配请求; 基站控制器在再次向基站收发器发送基本 信道建立请求时, 向移动台发送一条或多条等待通知信息。 优选地, 基站控制器通过特征通知消息发送等待通知信息。 优选地,基站控制器通过基站控制器的 A接口中的特征通知消息发送等 待通知信息。 优选地, 特征通知消息中携带有表示等待通知信息的文本信息。 根据本发明的另一个方面, 提供了一种应用于无线优先接入呼叫的基站 控制器, 包括: 接收模块, 用于在无线优先接入呼叫中, 接收基站收发器发 送的基本信道建立失败消息及移动交换子系统发送的指配请求; 发送模块, 用于在基站控制器再次向基站收发器发送基本信道建立请求时, 向移动台发 送一条或多条等待通知信息。 优选地, 发送模块, 用于通过特征通知消息发送等待通知信息。 优选地, 发送模块, 用于通过基站控制器的 A接口中的特征通知消息发 送等待通知信息。 优选地, 发送模块, 用于在特征通知消息中添加携带有表示等待通知信 息的文本信息。 通过本发明, 利用标准 A接口中的特征通知消息 ( Feature Notification Message ) 来通知用户等待, 解决了用户 4 队的过程中可能会由于误解而结 束呼叫的问题, 进而达到了提高用户体验的效果。 附图说明 此处所说明的附图用来提供对本发明的进一步理解, 构成本申请的一部 分, 本发明的示意性实施例及其说明用于解释本发明, 并不构成对本发明的 不当限定。 在附图中: 图 1是 居本发明实施例的等待通知方法的流程图; 图 2是根据本发明实例的无线优先接入呼叫的呼叫建立流程图; 图 3是根据本发明实施例的基站控制器的结构框图。 具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互组合。 图 1是根据本发明实施例的等待通知方法的流程图。 如图 1所示, 根据 本发明实施例的等待通知方法包括: 步骤 S 102, 基站控制器 ( Base Station Controller, 简称为 BSC )接收基 站收发器 ( Base Transceiver Station, 简称为 BTS )发送的基本信道建立失败 消息及移动交换子系统 ( Mobile Switching Subsystem, 简称为 MSS )发送的 指配请求。 步骤 S 104, 基站控制器在再次向基站收发器发送基本信道建立请求时, 向移动台 ( Mobile Station, 简称为 MS ) 发送一条或多条等待通知信息。 通过上述方法, 在无线优先接入呼叫建立的过程中, BSC在需要在用户 进行排队的时候提示用户正在进行资源排队,即可避免用户因为误解而挂机, 提高了用户体验。 优选地, 基站控制器可以通过特征通知消息发送上述等待通知信息。 特征通知消息是 MSS用来通知终端信息的一条无连接消息, 并且在该 消息中可以携带文本信息, 利用特征通知消息特来发送等待通知信息, 实现 最为方便。 优选地 ,基站控制器可以通过基站控制器的 A接口中的特征通知消息发 送上述等待通知信息。
A接口是广泛应用于中继侧的一种数字接口, 可以作为 BSC和 MSS之 间的直接接口。通常情况下,特征通知消息是由 MSS通过 A接口发送给 BSC, BSC再发送给 MS的。本发明中, BSC利用了这种 A接口中的特征通知消息, 直接构造这种特征通知消息发送给 MS , 通知用户等待。 优选地,特征通知消息中可以携带有表示上述等待通知信息的文本信息。 由于特征通知消息可以携带文本信息, 因此, 本发明中优先使用文本信 息的形式表示等待通知消息, 终端收到该消息后会在屏幕上显示相应的文本 信息。 下面根据实例及图 2对上述优选实施例进行详细说明。 如图 2所示, 根 据本发明实例的无线优先接入呼叫的呼叫建立流程包括: 步骤 S202:终端发起无线优先接入呼叫,即在被叫号码前加拨前缀号码, 如 *272; 步骤 S204: BTS收到起呼请求消息后转发给 BSC; 步骤 S206: BSC向交换机发送业务请求消息, 请求建立呼叫; 步骤 S208:与步骤 S206同步, BSC向 BTS发送基本信道建立请求消息; 步骤 S210: BTS收到基本信道建立请求消息后, 查看数据库开始分配无 线资源, 由于资源不足, 基本信道分配失败。 BTS向 BSC回复基本信道建立 失败消息, BSC收到该消息后不结束呼叫, 而是继续等待 MSS的指配请求 消息; 步骤 S212: MSS收到 BSC的业务请求消息后, 进行一系列的操作 (例 如, 鉴权等)后, 发现该呼叫为无线优先接入呼叫, 于是构造指配请求消息, 该消息中携带本次无线优先接入呼叫的优先级, 将指配请求消息发送给 BSC; 步骤 S214: BSC在收到了 MSS的指配请求以后, 知道该呼叫为无线优 先接入呼叫, 要进行第二次基本信道建立时, 构造一条特征通知消息, 消息 中携带文本信息通知用户等待, 其中, 该消息不需要终端回复证实; 步骤 S216:与步骤 S214同步, BSC再次向 BTS发送基本信道建立请求, 并且在基本信道建立请求消息中携带无线优先接入呼叫的优先级; BTS收到 基本信道建立请求后, 发现是无线优先接入呼叫, 并且此时资源不足, 因此 对该呼叫进行排队; 步骤 S218: 为了防止在 4 队过程中, 终端定时器 T ( 42m ) 超时而再次 发起起呼, BSC定时向终端发送状态查询消息,使终端始终保持在接入信道; 步骤 S220: 终端收到该消息后重新设置定时器 T ( 42m ) , 并返回状态查 询响应消息; 步骤 S222: BTS无线资源排队成功, 向 BSC发送基本信道建立成功消 息; 步骤 S224: BSC收到基本信道建立成功消息后, 给终端发扩展信道指配 消息, 终端转入业务信道; 步骤 S226: BSC成功分配其他资源以后, 给 MSS发送指配完成消息。 图 3是根据本发明实施例的基站控制器的结构框图。 如图 3所示, 根据 本发明实施例的基站控制器包括: 接收模块 32 , 用于在无线优先接入呼叫中, 接收基站收发器发送的基本 信道建立失败消息及移动交换子系统发送的指配请求。 发送模块 34 , 用于在基站控制器再次向基站收发器发送基本信道建立请 求时, 向移动台发送一条或多条等待通知信息。 由于只有基站子系统 ( Base Station Subsystem, 简称为 BSS ) 才知道无 线资源是否不足, 因此, 通知用户等待由 BSS来实现比较合理, 具体做法可 以是 BSC在收到了 MSS的指配请求以后,知道该呼叫为无线优先接入呼叫, 并且之前基本信道建立失败, 要进行第二次基本信道建立时, 构造一条特征 通知消息, 通知用户等待不要挂机。 优选地, 发送模块 34 , 可以用于通过特征通知消息发送上述等待通知信 息。 优选地,发送模块 34 ,可以用于通过基站控制器的 A接口中的特征通知 消息发送上述等待通知信息。 优选地, 发送模块 34 , 可以用于在特征通知消息中添加携带有表示上述 等待通知信息的文本信息。 利用标准 A接口中的特征通 口消息 ( Feature Notification Message )来通 知用户等待, 在实现上最为快捷方便, BSC在收到了 MSS的指配请求以后, 知道了该呼叫为无线优先接入呼叫且之前基本信道建立失败, 在发送第二次 基本信道建立请求消息时,构造一条特征通知消息,通知用户等待不要挂机, 该消息中可以携带文本信息以通知用户等待。 文本信息的设置可以根据不同 的应用场景来取不同的值。 从以上的描述中, 可以看出, 上述方案避免了无线优先呼叫用户在排队 的过程中可能会由于误解而结束呼叫, 使用户真正体-险到了无线优先呼叫的 便利, 从而提高了用户体验。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布 在多个计算装置所组成的网络上, 可选地, 它们可以用计算装置可执行的程 序代码来实现, 从而, 可以将它们存储在存储装置中由计算装置来执行, 并 且在某些情况下, 可以以不同于此处的顺序执行所示出或描述的步骤, 或者 将它们分别制作成各个集成电路模块, 或者将它们中的多个模块或步骤制作 成单个集成电路模块来实现。 这样, 本发明不限制于任何特定的硬件和软件 结合。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本 领域的技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的^"神和 原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护 范围之内。
