技术领域technical field
本发明涉及通信技术领域，尤其涉及一种实现组呼合并的方法及系统。The invention relates to the field of communication technology, in particular to a method and system for realizing group call merging.
背景技术Background technique
集群系统中，在一些场景下(如应急联动)要求不同组的成员能同时参与呼叫，提出组呼合并的需求，通过调度台将多个组临时合并为一个通话组，使分属于不同组的成员实现联合语音通信，同时不改变用户的操作，也就是说，组A和组B合并后，组A的成员呼叫组A，以及组B的成员呼叫组B，实际参与呼叫的都是组A和组B的成员(A+B)，但在用户角度和合并前没有任何差别。In the trunking system, in some scenarios (such as emergency linkage), it is required that members of different groups can participate in the call at the same time, and the demand for group call merging is put forward. Members realize joint voice communication without changing the user's operation. That is to say, after group A and group B are merged, members of group A call group A, and members of group B call group B, and those who actually participate in the call are group A and members of group B (A+B), but there is no difference in user perspective and before the merge.
现有技术通过动态重组操作可以把两个组合并为一个新组，或者把一个组合入另一个组，但这样一来终端需要保存合并后的组号并通知到用户，原子组的用户通过拨打合并后的组号而非子组组号发起合并组的呼叫，改变了用户的操作，无法满足组合并的业务需求。因此，在不改变用户操作的前提下，现有的动态重组操作无法满足组呼合并的业务需求。The existing technology can merge two groups into a new group through dynamic reorganization operation, or put one group into another group, but in this way, the terminal needs to save the merged group number and notify the user, and the user of the atomic group can dial The merged group number instead of the subgroup number initiates the merged group call, which changes the user's operation and cannot meet the business requirements of group merging. Therefore, under the premise of not changing the user operation, the existing dynamic reorganization operation cannot meet the service requirement of group call merging.

The dynamic reorganization message carries the dynamic reorganization operation identifier, the merged group attribute information obtained after the merge, the subgroup group number requested to be merged, and the merged identification bit ;
具体的，调度台发送的动态重组消息使用SIP请求消息的MESSAGE方法实现，所述组合并标识设置在所述SIP请求消息的扩展消息头中。Specifically, the dynamic reassembly message sent by the dispatcher is implemented using the MESSAGE method of the SIP request message, and the combination and identification is set in the extended message header of the SIP request message.
其中，所述组合并标识位用于指示本次操作为特定的动态重组(即组合并)过程，本实施例中的动态重组消息是在现有动态重组消息信元的基础上，扩展一个组合并标识位指示本次操作为特定的动态重组(组合并)过程；所述动态重组消息的现有信元包含动态重组操作标识、合并后得到的合并组组号、组名、组优先级属性信息、请求进行合并的子组组号等。Wherein, the combination and identification bit is used to indicate that this operation is a specific dynamic reorganization (that is, combination and combination) process, and the dynamic reorganization message in this embodiment is based on the existing dynamic reorganization message information element, expanding a combination And the identification bit indicates that this operation is a specific dynamic reorganization (combination and merging) process; the existing cell of the dynamic reorganization message includes the dynamic reorganization operation identification, the merged group number, group name, and group priority attribute obtained after the merger information, the subgroup number for which the merge is requested, etc.
S12、核心网设备根据所述动态重组消息，建立合并组，向各个子组中的每个子组终端下发动态重组指令，所述动态重组指令中携带有所述子组组号和合并组组号；S12. The core network device establishes a merging group according to the dynamic reorganization message, and sends a dynamic reorganization instruction to each subgroup terminal in each subgroup, and the dynamic reorganization instruction carries the subgroup group number and the merging group group No;

本实施例中，核心网设备在建立合并组后，合并组号通过特定的动态重组指令下发到子组终端，但合并组组号不通知到用户。每个子组终端在接收到特定的动态重组指令之后，根据该动态重组指令内部建立所述子组组号和合并组组号的映射关系，合并组信息不对该终端对应的用户进行显示。不影响用户操作，用户仍通过原子组组号进行呼叫，即可实现合并组的呼叫，用户体验较好。In this embodiment, after the core network device establishes the merged group, the merged group number is issued to the subgroup terminal through a specific dynamic reorganization command, but the merged group number is not notified to the user. After each subgroup terminal receives a specific dynamic reorganization instruction, it internally establishes a mapping relationship between the subgroup group number and the merged group number according to the dynamic reorganization instruction, and the merged group information is not displayed for the user corresponding to the terminal. It does not affect user operations, and the user can still call through the atomic group number, and the call of the merged group can be realized, and the user experience is better.

The group call is merged through the group number mapping on the terminal side, and only the call of the merged group is established in the downlink.
本发明实施例提出的实现组呼合并的方法，还包括：The method for realizing group call merging proposed by the embodiment of the present invention also includes:
核心网设备根据所述合并组的组呼区域，通知基站建立所述合并组的组呼通道。The core network device notifies the base station to establish the group call channel of the merged group according to the group call area of the merged group.

具体的，调度台通过动态重组操作将组A和组B合并为新组C，在现有的动态重组消息中扩展一个组合并标识，组合并标识用于指示本次操作为特定的动态重组(组合并)，指示空口需要特定的动态重组过程，集群核心网向子组终端下发的动态重组指令同时携带原子组号和合并后的新组号，终端收到后将原子组号和新组号进行映射，当用户发起所属子组呼叫时，终端自动将其映射为新组号向网络侧发起新组的呼叫建立请求，此后的呼叫建立过程为合并组的标准组呼建立。Specifically, the dispatcher merges group A and group B into a new group C through a dynamic reorganization operation, and expands a combination and identification in the existing dynamic reorganization message, and the combination and identification is used to indicate that this operation is a specific dynamic reorganization ( Combination), indicating that the air interface needs a specific dynamic reorganization process. The dynamic reorganization command issued by the cluster core network to the terminal of the subgroup carries the atomic group number and the new group number after the combination. When the user initiates a subgroup call, the terminal automatically maps it to the new group number and initiates a new group call establishment request to the network side. The subsequent call establishment process is the standard group call establishment of the merged group.
其中，在核心网设备向各个子组中的每个子组终端下发动态重组指令之前，所述方法进一步包括：Wherein, before the core network device issues a dynamic reorganization instruction to each subgroup terminal in each subgroup, the method further includes:
根据所述调度台发送的动态重组消息建立合并组，并根据所述消息中携带的组合并标识确定是否进行组合并；Establishing a merging group according to the dynamic reorganization message sent by the dispatcher, and determining whether to perform merging according to the combination identification carried in the message;

需要说明的是，本发明实施例中的终端、用户具有特定的含义，终端表示用户设备，用户表示使用终端的人。所述特定的动态重组指令发送到终端，但终端不通知到用户。用户拨打原所属子组的组号，通过终端将其自动映射为合并组的组号，此后的呼叫建立、话权申请、呼叫释放等流程均为合并组的标准流程。It should be noted that the terminal and the user in the embodiments of the present invention have specific meanings, the terminal means user equipment, and the user means a person using the terminal. The specific dynamic reorganization instruction is sent to the terminal, but the terminal does not notify the user. The user dials the group number of the subgroup to which he belongs, and the terminal automatically maps it to the group number of the merged group. After that, the processes of call establishment, talk right application, and call release are all standard processes of the merged group.
下面以基于TD-LTE的宽带集群通信系统为具体实施例，对本发明实现组呼合并的方法中涉及的消息扩展和呼叫建立过程进行具体描述，此时需要扩展的是D接口(调度台和集群核心网接口)的动态重组消息和NAS接口(终端和集群核心网接口)的组信息更新消息，具体如下：Taking the TD-LTE-based broadband trunking communication system as a specific embodiment below, the message extension and the call setup process involved in the method for realizing group call merging in the present invention are described in detail. What needs to be extended at this time is the D interface (dispatcher station and trunking station) Core network interface) dynamic reorganization message and NAS interface (terminal and cluster core network interface) group information update message, as follows:
1、D接口动态重组消息的扩展1. Extension of D interface dynamic reassembly message
D接口动态重组采用会话初始协议SIP(MESSAGE)消息，在ptt扩展消息头扩展一个组合并标识位(GC)，当发起组合并操作时携带该标识位且取值为1。The dynamic reassembly of the D interface uses the Session Initiation Protocol SIP (MESSAGE) message, and a combination flag (GC) is extended in the ptt extension message header. When the combination operation is initiated, the flag is carried and the value is 1.
组合并操作时SIP(MESSAGE)消息的扩展头示例如下，其中ptt-Extension为系统针对集群应用扩展的消息头：An example of the extension header of the SIP (MESSAGE) message during the merge operation is as follows, where ptt-Extension is the message header extended by the system for cluster applications:
Ptt-Extension:pttDGNA；GC＝1Ptt-Extension: pttDGNA; GC=1
其中，pttDGNA为动态重组操作标识，GC为组合并标识位；合并后得到的合并组组号、组名、组优先级属性信息、以及请求进行合并的子组组号在XML类型的消息体中携带，具体携带方式和现有标准相同。Among them, pttDGNA is the dynamic reorganization operation identification, and GC is the combination identification bit; the combination group number, group name, group priority attribute information obtained after the combination, and the subgroup group number requested to be combined are in the message body of XML type The specific carrying method is the same as the existing standard.
2、NAS接口组信息更新消息2. NAS interface group information update message
空口的动态重组指令通过组信息更新过程下发，组信息更新消息携带的组列表中，与合并组相关的表项包含的信元如表1下表所示，扩展一个SubGroup Number条件信元，当组合并操作时Group Number指示新组组号(合并组，组C)，SubGroup Number携带终端所属的原子组组号(组A)。终端收到组信息更新消息后，存储合并组信息，将子组组号和合并后的合并组组号进行映射。The dynamic reorganization command of the air interface is issued through the group information update process. In the group list carried by the group information update message, the information elements contained in the entries related to the merged group are shown in the following table of Table 1, and a SubGroup Number conditional information element is extended. The Group Number indicates the new group number (merged group, group C) during the merge operation, and the SubGroup Number carries the atomic group number (group A) to which the terminal belongs. After receiving the group information update message, the terminal stores the merged group information, and maps the group number of the subgroup with the merged group number after the merge.
表1组信息更新消息中与合并组相关的表项携带的信元Table 1 Information elements carried by entries related to the merged group in the group information update message
3、呼叫建立过程3. Call establishment process
子组A用户发起子组A呼叫时，终端发现子组A和合并组C建立了映射关系，在呼叫建立消息中自动把子组组号A映射为合并组组号C，向核心网发送合并组C的呼叫建立请求，此后的呼叫建立过程为合并组C的标准组呼建立，组呼释放、话权申请流程亦面向合并组C，此处不再赘述。When a subgroup A user initiates a subgroup A call, the terminal finds that a mapping relationship has been established between subgroup A and merged group C, and automatically maps subgroup number A to merged group number C in the call setup message, and sends the merged group number to the core network. The call establishment request of group C, the subsequent call establishment process is the standard group call establishment of the merged group C, the group call release and the speaking right application process are also for the merged group C, and will not be described here.
