本发明涉及数字集群通讯技术, 尤其涉及一种数字集群通讯系统中的 终端及实现其快速接听的方法。 背景技术
数字集群通讯系统是移动通讯系统的一个重要分支, 应用于集团调度 指挥通讯, 如政府部门、 军队、 警务、 铁路、 水利、 民航及钢铁物流等专 业移动通讯领域。
图 1为现有数字集群通讯系统中的终端内部结构示意图, 如图 1所示, 该终端主要包括主控器件 1、 外围电路 2、 外围控制芯片 3及外围器件 4; 具体的:
主控器件 1 ,是终端的主要控制部分,一般一个终端仅有一个主控器件, 该主控器件 1内部集成了 CPU和对外收发信号的器件,是这个终端的心脏; 外围电路 2, 是终端辅助设备, 为主控器件 1或外围控制芯片 3提供电 源或提供存储和交互环境, 一般没有处理运算能力, 为终端的硬件部分; 外围控制芯片 3简称控制芯片, 是终端辅助设备, 辅助主控器件 1管 理外围电路 2和外围器件 4, 或代替主控器件 1处理一些复杂信息, 具有一 定的处理运算能力;
外围器件 4, 是终端外围设备, 没有处理运算能力, 为外围输入、 输出 设备, 如液晶显示器(LCD )、 发光二极管 (LED )、 键盘、 扬声器等。
其中, 所述终端可以是手机、 车载台或者其他数字集群终端。
主控器件 1不直接对外围器件 4进行如显示、 声音设备控制等管理, 而是通过发送 AT指令给控制芯片 3以实现对外围器件 4的管理。 所有的 AT指令均以 +为开头, 后面附带命令名称, 如响铃操作 RING、 来电号码显 示 CLIP或 INCOMING, 业务界面显示 ZCCNT等。
图 2为现有数字集群通讯系统中的终端接听普通语音呼叫的流程示意 图, 该终端接听集群呼叫的流程与接听普通语音呼叫的流程相同。 如图 2 所示, 终端接听流程为:
终端收到系统侧发来的寻呼消息信令后, 终端返回寻呼响应消息信令 给系统侧, 且终端通过如亮屏的方式进行准备通知用户显示; 在收到系统 侧发来的信道指配消息信令后, 终端等待振铃和来电号码消息信令。 收到 系统侧发来的振铃和来电号码消息信令后, 终端的主控器件发送来电号码 显示消息( + CLIP: XXX或 + INCOMING: XXX, 其中 XXX为来电号码 ) 给控制芯片, 通知控制芯片作来电号码显示工作, 等待用户作应答响应。 终端的主控器件接收控制芯片发来的用户应答消息, 并向系统侧回复用户 应答消息信令。 如果用户应答消息为肯定应答消息, 即用户接听, 则终端 的主控器件发送业务界面显示消息 ( + ZCCNT: )给控制芯片, 进行业务界 面显示, 并开始接听系统侧发来的语音信息; 如果用户应答消息为否定应 答消息, 即用户拒绝接听, 则系统侧终止呼叫, 终端的主控器件发送结束 呼叫消息给控制芯片, 本次呼叫结束。
上述方案中,终端的主控器件通过发送 AT指令给控制芯片以实现对外 围器件的管理, 该 AT指令为串口传输, 速度相对较慢, 因此, 如何优化主 控器件与控制芯片之间的 AT指令, 提高终端工作效率, 尤其是在集群呼叫 中, 成为优化终端甚至是整个数字集群系统的重要工作。 发明内容
有鉴于此, 本发明的主要目的在于提供一种数字集群通讯系统中的终 端及实现其快速接听的方法, 能够缩短数字集群通讯系统中终端接听集群 呼叫的时间。 为达到上述目的, 本发明的技术方案是这样实现的:
本发明提供一种实现数字集群通讯系统中的终端快速接听的方法, 该 方法包括:
终端的主控器件在收到系统侧发来的信道指配消息信令后, 建立业务 信道, 并判断呼叫类型, 若为普通语音呼叫, 则执行语音模式流程, 若为 集群呼叫, 则主控器件直接发送业务界面显示消息给终端的控制芯片; 控制芯片根据所述业务界面显示消息进行业务界面显示, 接听并播放 系统侧发来的语音信息。

其中, 所述终端为手机或车载台。
本发明的数字集群通讯系统中的终端及实现其快速接听的方法, 通过 改变和优化数字集群通讯系统中终端的主控器件与控制芯片在接通过程中 显示流程的交互方式, 减少了主控器件与控制芯片之间的传输信息, 终端 收到信道指配消息信令时默认接听, 而不用等待用户按键实现接听, 缩短 了数字集群通讯系统中终端接听集群呼叫的时间, 从而更适应数字集群系 统下的终端快速接入和显示的要求, 更好地满足了数字集群用户的需求。 附图说明

图 2为现有数字集群通讯系统中的终端接听普通语音呼叫的流程示意 图;
图 3为本发明数字集群通讯系统中的终端接听集群呼叫的流程示意图; 图 4为本发明实现数字集群通讯系统中的终端快速接听的方法流程示 意图。 具体实施方式
本发明的基本思想是: 通过改变和优化数字集群通讯系统中终端的主 控器件与控制芯片在接通过程中显示流程的交互方式, 在终端收到集群呼 叫时, 减少了主控器件与控制芯片之间的传输信息, 终端收到系统侧发来 的信道指配消息信令后默认接听, 而不用等待用户按键实现接听, 加快了 终端的接入速度, 实现了数字集群通讯系统中终端的快速接听。
图 3为本发明数字集群通讯系统中的终端接听集群呼叫的流程示意图, 如图 3所示, 终端接听流程为:
终端的主控器件收到系统侧发来的寻呼消息信令后, 终端返回寻呼响 应消息信令给系统侧; 收到系统侧发来的信道指配消息信令后, 终端根据 信道指配消息信令中指配模式( ASSIGN— MODE ) 字段内容, 判断本次呼 叫的呼叫类型, 即此次呼叫为普通语音呼叫 (原始模式)还是集群呼叫。 如果是普通语音呼叫, 则终端釆用语音模式流程, 此流程与现有技术相同, 故不再赘述; 如果是集群呼叫, 终端默认用户已经应答了此次呼叫, 不再 向用户询问是否应答, 直接向控制芯片发送业务界面显示消息( + ZCCNT: 类型), 携带此次呼叫的类型 (即为集群呼叫), 通知控制芯片进行业务界 面显示, 接听并播放系统侧发来的语音信息。
在发送集群呼叫时, 系统侧默认用户接听, 在发送信道指配消息信令 后, 直接发送语音消息给终端; 或者
终端在判断呼叫为集群呼叫时, 直接发送用户肯定应答消息信令给系 统侧, 收到该信令后, 系统侧发送语音消息给终端。
图 4为本发明实现数字集群通讯系统中的终端快速接听的方法流程示 意图, 如图 4所示, 该终端快速接听实现方法包括:

步骤 11、 主控器件在收到系统侧发来的信道指配消息信令后, 建立业 务信道。
步骤 12、 主控器件判断本次呼叫是否为集群呼叫, 若不是集群呼叫, 则执行步骤 13 , 若是集群呼叫, 则执行步骤 14;
本步骤中, 主控器件根据信道指配消息信令中 ASSIGN— MODE字段内 容, 判断本次呼叫的呼叫类型, 如果 ASSIGN— MODE字段内容为 100或者 110, 则判断本次呼叫为集群呼叫, 否则判断本次呼叫为普通语音呼叫。 实 际应用中, ASSIGN— MODE字段内容并不以此为限, 也可以通过预先定义 的方式设定 ASSIGN— MODE字段内容, 以区分呼叫类型。
步骤 13、 主控器件执行语音模式流程;
本步骤中, 语音模式流程为现有技术, 在此不再赘述。
步骤 14、 主控器件直接发送业务界面显示消息给终端的控制芯片, 控 制芯片根据该业务界面显示消息进行业务界面显示, 接听并播放系统侧发 来的语音信息。
本发明还提供了一种实现上述快速接听的方法的数字集群通讯系统中 的终端, 该终端包括主控器件和控制芯片; 具体的:
主控器件, 用于在收到系统侧发来的信道指配消息信令后, 建立业务 信道, 在呼叫为集群呼叫时, 发送业务界面显示消息给控制芯片; 控制芯片, 用于根据所述业务界面显示消息进行业务界面显示, 接听 并播放系统侧发来的语音信息。
本发明在集群呼叫过程中, 通过改变和优化数字集群通讯系统中终端 的主控器件与控制芯片在接通过程中的交互方式, 减少了主控器件与控制 芯片之间的 AT传输信息 (省略了响铃等操作 ) , 由原来的 3条 AT传输信 息变为 1条 AT传输信息, 降低了控制芯片的处理难度, 更符合集群系统的 要求, 从而更适应数字集群下的终端接听快速接入和显示的工作, 更好地 满足数字集群用户的要求。
