数字集群互联方法、系统及控制设备
【技术领域】
本发明涉及通信技术领域，特别是涉及一种数字集群互联方法、系统及控制设备。
【背景技术】
TETRA是欧洲通信标准协会（ETSI）为了满足欧洲各国专业部门对专有无线通信的需求而设计的，我国于2000年将TETRA中国集群通信推荐型的四个标准之一。
目前，在国内的TETRA无线通信系统的建设中，TETRA系统间互联标准缺失，各个厂家间不开放接口等原因，造成不同厂家生产的TETRA交换机间无法直接互联。
现在通用的解决互联问题的方案是以车台作为无线互联通道，部署车台分别连接到需要进行互联的系统，每个车台负责固定的一个或者几个组的互联。当一个系统中的某一组被呼叫时，负责该组号的车台发送信令将另一系统中对应的组叫起。若每个车台负责多个组，成本低且车台利用率高，但呼叫的过程中，由该车台负责的其它通话组无法进行通信，影响通话效率。若每个车台负责一个组，不会存在呼叫起的通话组影响同一车台的其他通信组的问题，通话效率得到保障，但成本高且车台的利用率低。
【发明内容】
为了至少部分解决以上问题，本发明提出了一种数字集群互联方法。该数字集群互联方法包括：控制设备设置车台与多个通话组的对应关系，以使得车台可以对具有对应关系的通话组进行扫描，车台用于第一、第二数字集群系统的互联；控制设备根据通话组的呼叫状态变化动态调整对应关系，动态调整至少包括在通话组的呼叫状态由未呼叫变为被呼叫的情况下，将被叫起的原车台扫描的其他通话组交由其他未被叫起的车台进行扫描。
其中，控制设备设置车台与多个通话组的对应关系包括：控制设备将车台至少划分为主车台和自由车台，在所有通话组的呼叫状态均为未呼叫的情况下，设置主车台与通话组之间有对应关系，自由车台与通话组之间没有对应关系。
其中，控制设备根据通话组的呼叫状态变化动态调整对应关系包括：通话组的呼叫状态由未呼叫变为被呼叫时，若存在未被叫起的空闲自由车台，则控制设备将被叫起的原车台扫描的其他通话组交由空闲自由车台进行扫描；被呼叫的通话组的呼叫状态变为未呼叫时，控制设备将未呼叫的其他通话组交由原车台或未被叫起的初始主车台进行扫描，并在原车台为自由车台且初始主车台未被叫起的情况下，将被呼叫的通话组交由未被叫起的初始主车台进行扫描，初始主车台与被呼叫的通话组之间在所有通话组的呼叫状态均为未呼叫的情况下存在对应关系。
其中，控制设备进一步将部分车台划分为预占车台，预占车台对应的通话组的优先级高于主车台对应的通话组。
其中，控制设备根据通话组的呼叫状态变化动态调整对应关系包括：高优先级通话组的呼叫状态由未呼叫变为被呼叫时，判断是若存在未被叫起的空闲自由车台；若存在，则控制设备将被叫起的预占车台扫描的其他高优先级通话组交由空闲自由车台进行扫描，若不存在，则判断是否存在未被叫起的空闲主车台；若存在，则控制设备将其他高优先级通话组交由空闲主车台进行扫描，若不存在，则选择一个自由车台挂断当前呼叫，将其他高优先级通话组交由选中的自由车台进行扫描；高优先级通话组的呼叫状态变为未呼叫时，控制设备将未呼叫的其他高优先级通话组交由预占车台进行扫描。
其中，控制设备设置车台与多个通话组的对应关系包括：控制设备根据通话组的重要性、优先级、呼叫频繁程度中的至少一种设置车台与通话组的对应关系。
其中，车台通过通话组与第一数字集群系统通信，控制设备分别连接车台及第二数字集群系统；进一步包括：通话组的呼叫过程中，控制设备在对应的车台与第二数字集群系统之间传输数据，以实现第一数字集群系统与第二数字集群系统之间的互联。
为了至少部分解决以上问题，本发明提出了一种数字集群互联系统。该数字集群互联系统包括：控制设备、至少两个车台以及第一、第二数字集群系统；控制设备连接车台，用于设置车台与多个通话组的对应关系，根据通话组的呼叫状态变化动态调整对应关系，动态调整至少包括在通话组的呼叫状态由未呼叫变为被呼叫的情况下，将被叫起的原车台扫描的其他通话组交由其他未被叫起的车台进行扫描；车台用于第一、第二数字集群系统的互联，可以对具有对应关系的通话组进行扫描。
其中，车台通过通话组与第一数字集群系统通信，控制设备还连接第二数字集群系统；通话组的呼叫过程中，控制设备还用于在对应的车台与第二数字集群系统之间传输数据，以实现第一数字集群系统与第二数字集群系统之间的互联。
其中，车台通过向第一数字集群系统发送附属/去附属信令以改变车台扫描的通话组。
为了至少部分解决以上问题，本发明提出了一种控制设备。该控制设备包括：设置模块，用于设置车台与多个通话组的对应关系，以使得车台可以对具有对应关系的通话组进行扫描，车台用于第一、第二数字集群系统的互联；调整模块，用于根据通话组的呼叫状态变化动态调整对应关系，动态调整至少包括在通话组的呼叫状态由未呼叫变为被呼叫的情况下，将被叫起的原车台扫描的其他通话组交由其他未被叫起的车台进行扫描。
为了至少部分解决以上问题，本发明提出了一种控制设备。该控制设备包括：处理器及通信电路，处理器连接通信电路；处理器用于通过通信电路设置车台与多个通话组的对应关系，以使得车台可以对具有对应关系的通话组进行扫描，车台用于第一、第二数字集群系统的互联；根据通话组的呼叫状态变化动态调整对应关系，动态调整至少包括在通话组的呼叫状态由未呼叫变为被呼叫的情况下，通过通信电路将被叫起的原车台扫描的其他通话组交由其他未被叫起的车台进行扫描。
其中，处理器用于将车台至少划分为主车台和自由车台，在所有通话组的呼叫状态均为未呼叫的情况下，通过通信电路设置主车台与通话组之间有对应关系，自由车台与通话组之间没有对应关系。
其中，处理器用于当通话组的呼叫状态由未呼叫变为被呼叫时，若存在未被叫起的空闲自由车台，则通过通信电路将被叫起的原车台扫描的其他通话组交由空闲自由车台进行扫描；当被呼叫的通话组的呼叫状态变为未呼叫时，通过通信电路将未呼叫的其他通话组交由原车台或未被叫起的初始主车台进行扫描，并在原车台为自由车台且初始主车台未被叫起的情况下，通过通信电路将被呼叫的通话组交由未被叫起的初始主车台进行扫描，初始主车台与被呼叫的通话组之间在所有通话组的呼叫状态均为未呼叫的情况下存在对应关系。
其中，处理器进一步用于通过通信电路将部分车台划分为预占车台，预占车台对应的通话组的优先级高于主车台对应的通话组。
其中，处理器用于当高优先级通话组的呼叫状态由未呼叫变为被呼叫时，判断是若存在未被叫起的空闲自由车台；若存在，则通过通信电路将被叫起的预占车台扫描的其他高优先级通话组交由空闲自由车台进行扫描，若不存在，则判断是否存在未被叫起的空闲主车台；若存在，则通过通信电路将其他高优先级通话组交由空闲主车台进行扫描，若不存在，则选择一个自由车台挂断当前呼叫，通过通信电路将其他高优先级通话组交由选中的自由车台进行扫描；当高优先级通话组的呼叫状态变为未呼叫时，通过通信电路将未呼叫的其他高优先级通话组交由预占车台进行扫描。
本发明的有益效果是：通过设置车台与多个通话组的对应关系，并根据通话组的呼叫状态变化动态调整对应关系，实现了车台资源的动态分配。在有通话组被呼叫的情况下，将被叫起的原车台扫描的其他通话组交由其他未被叫起的车台进行扫描，如果其他通话组中的任意一个被呼叫，则由当前对其扫描的车台响应呼叫，对比于现有技术中必须等待原车台结束叫起才能响应，降低对通话效率的影响，因此在保障通话效率的同时可以降低所需的车台数量，从而降低成本并提高车台的利用率。

【具体实施方式】
下面结合附图和实施方式对本发明进行详细说明。
如图1所示，本发明数字集群互联方法第一实施例包括：
S1：控制设备设置车台与多个通话组的对应关系。
控制设备连接车台，车台用于第一、第二数字集群系统的互联。控制设备设置完成之后将具有对应关系的通话组发给各个车台以控制车台对具有对应关系的通话组进行扫描。如果通过通话组与车台直接通信的数字集群系统呼叫通话组，对应的车台响应呼叫并发送信令将另一系统中对应的组叫起，以实现两个数字集群系统的互联。车台可以通过通话组与第一数字集群系统直接通信，也可以通过通话组与第二数字集群系统直接通信。
车台的数量大于或等于2，且在默认状态，即所有通话组的呼叫状态为未呼叫的情况下，至少一个车台对应的通话组的数量大于或者等于2。每个通话组只对应一个车台。
S2：控制设备根据通话组的呼叫状态变化动态调整对应关系。
该动态调整至少包括在通话组的呼叫状态由未呼叫变为被呼叫的情况下，将被叫起的原车台扫描的其他通话组交由其他未被叫起的车台进行扫描。被呼叫的通话组在呼叫之前由原车台进行扫描，调整对应关系之后，呼叫过程中原车台不扫描其他通话组。其他未被叫起的车台在默认状态下可以对应部分通话组，也可以不对应任何通话组。控制设备可以将调整内容或者调整之后的对应关系发给相应的车台，以使其改变扫描的通话组。
车台具有动态开关组扫描功能，利用该功能通过空中接口向直接通信的第一/第二数字集群系统发送附属/去附属信令以改变车台扫描的通话组。
举例说明，车台A、B和C与第一数字集群系统直接通信，默认状态下，控制设备设置车台A对应通话组1和2，车台B对应通话组3-5，车台C对应通话组6-8，第一集群系统呼叫通话组3，车台B被叫起，此时控制设备将原本由车台B扫描的通话组4和5交由车台A和车台C中的至少一个扫描，车台B不扫描通话组4和5。
通过上述实施例的实施，实现了车台资源的动态分配。在有通话组被呼叫的情况下，将被叫起的原车台扫描的其他通话组交由其他未被叫起的车台进行扫描，如果其他通话组中的任意一个被呼叫，则由当前对其扫描的车台响应呼叫，对比于现有技术中必须等待原车台结束叫起才能响应，降低对通话效率的影响，因此在保障通话效率的同时可以降低所需的车台数量，从而降低成本并提高车台的利用率。
本发明数字集群互联方法第二实施例，是在本发明数字集群互联方法第一实施例的基础上，控制设备将车台划分为主车台和自由车台，同一类型的车台组成了一个资源池。在默认状态，即所有通话组的呼叫状态为未呼叫的情况下，主车台与通话组之间有对应关系，自由车台与通话组之间没有对应关系。
如图2所示，本实施例中，控制设备根据通话组的呼叫状态变化动态调整对应关系具体包括：
S11：通话组的呼叫状态由未呼叫变为被呼叫时，控制设备判断是否存在未被叫起的空闲自由车台。
若存在，则跳转到步骤S12，若不存在，则跳转到步骤S18。
S12：控制设备将被叫起的原车台扫描的其他通话组交由空闲自由车台进行扫描。
被叫起的原车台为前述被呼叫的通话组被呼叫之前负责扫描的车台，原车台可以为主车台，也可以为自由车台。
S13：被呼叫的通话组的呼叫状态变为未呼叫时，控制设备判断原车台是否为初始主车台。
若是，则跳转到步骤S14，若否，则跳转到步骤S15。
S14：控制设备将未呼叫的其他通话组交由初始主车台进行扫描。
执行完成后结束此次流程。
S15：控制设备判断初始主车台是否被叫起。
若是，则跳转到步骤S16，若否，则跳转到步骤S17。
S16：控制设备将未呼叫的其他通话组交由原车台进行扫描。
执行完成后结束此次流程。
S17：控制设备将未呼叫的其他通话组以及被呼叫的通话组交由初始主车台进行扫描。
如果此时未呼叫的其他通话组均已经由初始主车台进行扫描，则控制设备可以只将被呼叫的通话组交由初始主车台进行扫描。执行完成后结束此次流程。
S18：控制设备不调整对应关系。
被叫起的原车台扫描的其他通话组处于等待状态无法通信，呼叫结束后才能通信。结束此次流程。
举例说明，车台a、b、c和d与第一数字集群系统直接通信，控制设备将车台a和b分配为主车台，将车台c和d划分为自由车台，在默认状态下，控制设备设置主车台a扫描通话组1-5，主车台b扫描组6至10。
第一数字集群系统呼叫通话组1，主车台a被叫起，控制设备将通话组2-5交由自由车台c 进行扫描，此时主车台a只响应当前呼叫，不扫描通话组2-5。通话组1呼叫过程中，第一数字集群系统呼叫通话组2。此时通话组2-5由自由车台c负责扫描，通话组2的呼叫由自由车台c处理，控制设备将通话组3-5交由自由车台d进行扫描。通话组1和2呼叫过程中，第一数字集群系统呼叫通话组3。此时通话组3-5由自由车台d进行扫描，通话组3的呼叫由自由车台d处理，由于没有空闲的自由车台，控制设备不调整对应关系，通话组4和5仍由自由车台d进行扫描，但处于等待状态无法通信。
通话组2先结束呼叫，此时通话组1和3仍在呼叫中，控制设备将通话组4和5交由自由车台c进行扫描，自由车台c扫描通话组2、4和5。随后通话组1结束呼叫，此时通话组3仍在呼叫中，控制设备将通话组2、4和5交由主车台a进行扫描，主车台a扫描通话组1、2、4和5。最后通话组3结束呼叫，此时主车台a未被叫起，控制设备将通话组3交由主车台a进行扫描，主车台a扫描通话组1-5，回归默认状态。
通过上述实施例的实施，将车台划分为主车台和自由车台，采用组合分配策略，实现车台资源的最大化利用。
本实施例中，有新呼叫的情况下，控制设备不会将通话组转移给主车台。在其他实施例中，控制设备也可以选择在有新呼叫且没有空闲自由车台的情况下，将其他通话组交由空闲的主车台扫描。仍以前述例子为例，当自由车台d被叫起时，控制设备将通话组4和5交由空闲的主车台b进行扫描。
本发明数字集群互联方法第三实施例，是在本发明数字集群互联方法第二实施例的基础上，控制设备进一步将部分车台划分为预占车台，即将所有车台划分为主车台、自由车台和预占车台三种。在默认状态下，主车台、预占车台与通话组之间均有对应关系，且预占车台对应的通话组的优先级高于主车台对应的通话组，自由车台与通话组之间没有对应关系。
预占车台对应的高优先级通话组在任何情况下都应该有至少一个空闲车台负责扫描，以保证其呼叫不受影响。一般来说，高优先级通话组为紧急呼叫组。为保证高优先级通话组的呼叫不受影响，避免频繁的调整，每个预占车台对应的高优先级通话组的数量应该少，例如1个或2个。
如图3所示，本实施例中，控制设备根据通话组的呼叫状态变化动态调整对应关系进一步包括：
S21：高优先级通话组的呼叫状态由未呼叫变为被呼叫时，判断是若存在未被叫起的空闲自由车台。
若存在，则跳转到步骤S22；若不存在，则跳转到步骤S23。
S22：将其他高优先级通话组交由空闲自由车台进行扫描。
被呼叫之前，被呼叫的高优先级通话组和其他高优先级通话组均由被叫起的预占车台扫描。呼叫过程中被叫起的预占车台不扫描其他高优先级通话组。呼叫结束后跳转到步骤S26。
S23：判断是否存在未被叫起的空闲主车台。
若存在，则跳转到步骤S24；若不存在，则跳转到步骤S25。
S24：将其他高优先级通话组交由空闲主车台进行扫描。
呼叫结束后跳转到步骤S26。
S25：选择一个自由车台挂断当前呼叫，将其他高优先级通话组交由选中的自由车台进行扫描。
选中的自由车台可以为呼叫中的通话组呼叫频率的一个、通话时长最长的一个或者通话时长最短的一个对应的自由车台。呼叫结束后跳转到步骤S26。
S26：高优先级通话组的呼叫状态变为未呼叫时，将未呼叫的其他高优先级通话组交由预占车台进行扫描。
结束流程。
上述步骤中只描述了高优先级通话组由预占车台扫描的情况下被呼叫的情况，如果单个预占车台对应的高优先级通话组的数量多于2个，出现了高优先级通话组由主车台或自由车台扫描时被呼叫，且需要转移被叫起的主车台或自由车台对应其他高优先级通话组的情况，类似的，转移其他高优先级通话组的对象按优先级从高到低排列可以依次为：空闲自由车台、空闲主车台、选中的挂断呼叫的自由车台。这种情况下呼叫结束之后的对应关系调整可参考本发明数字集群互联方法第二实施例中的对应描述。
本实施例的执行主体为控制设备。主车台对应的低优先级通话组的呼叫状态发生变化的情况下，控制设备动态调整对应关系的内容可参考本发明数字集群互联方法第二实施例，在此不再赘述。
通过上述实施例的实施，将车台划分为预占车台、主车台和自由车台，采用组合分配策略，实现车台资源的最大化利用的同时保障高优先级通话组的通话效率不受影响。
如图4所示，本发明数字集群互联方法第四实施例，是在本发明数字集群互联方法第一实施例的基础上，车台通过通话组与第一数字集群系统通信，控制设备分别连接车台及第二数字集群系统，且进一步包括步骤：
S3：通话组的呼叫过程中，控制设备在对应的车台与第二数字集群系统之间传输数据。
第一数字集群系统发起呼叫，业务数据通过车台和控制设备传送到第二数字集群系统，以实现第一数字集群系统与第二数字集群系统之间的互联。
反过来，也可以是车台通过通话组与第二数字集群系统通信，控制设备分别连接车台及第一数字集群系统，并在通话组的呼叫过程中，在对应的车台与第一数字集群系统之间传输数据。
本实施例可以与以上任一实施例相结合。
在本发明数字集群互联方法一个实施例中，控制设备根据通话组的重要性、优先级、呼叫频繁程度中的至少一种设置车台与通话组的对应关系。本实施例可以与以上任一实施例相结合。
控制设备可以根据通话组的重要性、优先级、呼叫频繁程度中的至少一种按照预设的配置策略设置对应关系。例如，为避免频繁调整对应关系而带来的车台频繁修改扫描组，影响车台空口响应性能，并保证负载均衡，设置对应关系的时候可以将呼叫频繁程度高和低的通话组搭配分配给一个车台，使得每个车台对应的通话组呼叫频繁程度有高有低。为保证高重要性/优先级的通话组的通话效率，对应高重要性/优先级的通话组的车台可以设置为只扫描少量的通话组，例如1个或2个。
如图5所示，本发明数字集群互联系统第一实施例包括：至少两个车台101、控制设备102、第一数字集群系统103、以及第二数字集群系统104。
控制设备102连接车台，用于设置车台101与多个通话组的对应关系，根据通话组的呼叫状态变化动态调整对应关系，该动态调整至少包括在通话组的呼叫状态由未呼叫变为被呼叫的情况下，将被叫起的原车台扫描的其他通话组交由其他未被叫起的车台进行扫描。控制设备102的功能的具体内容以及可行的扩展可参考本发明数字集群互联方法对应实施例及可行的结合中的描述，在此不再重复。
车台101用于第一数字集群系统103、第二数字集群系统104之间的互联，可以在控制设备102的控制下对具有对应关系的通话组进行扫描。车台101具有动态开关组扫描功能，利用该功能通过空中接口向直接通信的数字集群系统（图中为第一数字集群系统103）发送附属/去附属信令以改变车台扫描的通话组。
为实现第一、第二数字集群系统之间信息的实时传递，系统中可进一步包括互联设备，互联设备分别连接（有线或无线）第二数字集群系统及车台，用于两者之间的数据传输。例如使用传输车台（图中未画出）作为互联设备。传输车台的数量可以为一个或者至少两个，传输车台通过空中接口与第二数字集群系统通信，连接车台，连接关系可以是一对一的，也可以是一对多的，且每个车台都连接至少一个传输车台，每个传输车台都连接至少一个车台。传输车台与车台之间可以直接连接，也可以通过交换机连接。假设第一数字集群系统发起呼叫，车台中的一个被叫起，并将收到的信号发给对应的传输车台，对应的传输车台向第二数字集群系统发起呼叫，实现第一数字集群系统向第二数字集群系统发起的实时呼叫。同理反过来可实现第二数字集群系统向第一数字集群系统发起实时呼叫。
如图6所示，本发明数字集群互联系统第二实施例，是在本发明数字集群互联系统第一实施例的基础上，车台201通过通话组与第一数字集群系统203通信，控制设备202还连接第二数字集群系统204。通话组的呼叫过程中，控制设备202还用于在对应的车台201与第二数字集群系统204之间传输数据，以实现第一数字集群系统203与第二数字集群系统204之间的互联。
本实施例中控制设备还作为互联设备，在车台与第二数字集群系统之间传输数据，不用使用额外的设备，降低成本。此外，与车台和第二数字集群系统有线连接的控制设备可以避免使用传输车台作为互联设备时对车台造成的干扰。
如图7所示，本发明控制设备第一实施例包括：
设置模块11，用于设置车台与多个通话组的对应关系，以使得车台可以对具有对应关系的通话组进行扫描，车台用于第一、第二数字集群系统的互联。
调整模块12，用于根据通话组的呼叫状态变化动态调整对应关系，该动态调整至少包括在通话组的呼叫状态由未呼叫变为被呼叫的情况下，将被叫起的原车台扫描的其他通话组交由其他未被叫起的车台进行扫描。
如图8所示，本发明控制设备第二实施例包括：
处理器110和通信电路120，处理器110通过总线连接通信电路120。
通信电路120用于发送和接收数据，是控制设备与其他通信设备进行通信的接口。
处理器110控制控制设备的操作，处理器110还可以称为CPU（Central Processing Unit，中央处理单元）。处理器110可能是一种集成电路芯片，具有信号的处理能力。处理器110还可以是通用处理器、数字信号处理器（DSP）、专用集成电路（ASIC）、现成可编程门阵列（FPGA）或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件。通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等。
控制设备可以进一步包括存储器（图中未画出），存储器用于存储处理器110工作所必需的指令及数据，设置对应关系所需的参数和/或配置策略，也可以存储通信电路120接收的数据。
处理器110用于通过通信电路120设置车台与多个通话组的对应关系，以使得车台可以对具有对应关系的通话组进行扫描，车台用于第一、第二数字集群系统的互联；根据通话组的呼叫状态变化动态调整对应关系，该动态调整至少包括在通话组的呼叫状态由未呼叫变为被呼叫的情况下，通过通信电路120将被叫起的原车台扫描的其他通话组交由其他未被叫起的车台进行扫描。
可选的，处理器用于将车台至少划分为主车台和自由车台，在所有通话组的呼叫状态均为未呼叫的情况下，通过通信电路设置主车台与通话组之间有对应关系，自由车台与通话组之间没有对应关系。
