Technical Field
The invention belongs to the technical field of private network cluster communication, and particularly relates to a method and a device for determining a group call key event of a private network cluster terminal.
Background
The private network cluster communication refers to a communication network established in some industries, departments or units for meeting the needs of organization and management, safe production, dispatching and commanding, and the service object of the communication network is often an industry or an enterprise.
The equipment provider of a private network trunking terminal typically extends some special keys for initiating specific services. For example, some private network terminals add a group call service initiation key (PTT button) and an emergency call button (SOS button), so that a user can initiate a group call service by pressing the PTT button, and can initiate an emergency call service by pressing the emergency call button.
The extension keys of a plurality of device providers have commonality, that is, a specific key value needs to be defined for each extension key based on the key value system definition specification of the android system. When the group calling software of the third party manufacturer needs to process the extended key, the extended key must be processed by using the specific key.
However, the number of expansion keys and the difference in key values of the respective device providers are unavoidable. For example, the definitions of group call keys and other keys by the respective device providers depend on specific hardware, and the number of keys and specific key values are determined by the respective device providers and are difficult to unify. If the key values of the group call keys are not consistent on different devices, the unified group call service processing needs to be adapted to different devices. On one hand, extra workload is brought, on the other hand, the addition of new equipment hardware is also limited, and the popularization and the use of unified group calling software are not facilitated in the long term.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the accompanying drawings.
For simplicity and clarity of description, the invention will be described below by describing several representative embodiments. Numerous details of the embodiments are set forth to provide an understanding of the principles of the invention. It will be apparent, however, that the invention may be practiced without these specific details. Some embodiments are not described in detail, but rather are merely provided as frameworks, in order to avoid unnecessarily obscuring aspects of the invention. Hereinafter, "comprising" means "including but not limited to", "according to … …" means "at least according to … …, but not limited to … … only". In view of the language convention of chinese, the following description, when it does not specifically state the number of a component, means that the component may be one or more, or may be understood as at least one.
Fig. 1 is a flowchart of a method for determining a group call keying event of a private network cluster terminal according to the present invention.
As shown in fig. 1, the method includes:
step 101: and establishing a corresponding relation between the key values of the group calling keys of the private network cluster terminal and the broadcast events.
Here, the group call button of the private network cluster terminal may include a PTT button or an SOS button. Wherein, the PTT button corresponds to a general group call service, and the SOS button corresponds to an emergency call service (belonging to a special group call service).
For example, fig. 2 is a schematic diagram of a group call key of a private network cluster terminal according to the present invention.
It can be seen that the private network cluster terminal 20 includes an antenna 21 and a menu key (menu), a home key (home), and a back key (back) which are conventionally arranged. Also, the private network cluster terminal 20 is also arranged with a PTT button 23 or SOS button 22. The user can start group call service by pressing the PTT key 23, and can start emergency call service by pressing the emergency call key 22.
The key value of the group call key may be different considering the difference of the device providers of the private network cluster terminal. Here, for the group call keys of the private network cluster terminals provided by different hardware terminals, no matter how many specific key values are defined, the key values are uniformly converted into specific broadcast events. For example, the broadcast event includes the name of the group call key.
For example, assuming that the key value defined by the device provider a of the private network trunking terminal for the PTT button on the private network trunking terminal produced by itself is 235, in step 101, the key value (235) is corresponding to the broadcast event containing the PTT button name.
For another example, assuming that the device provider B of the private network trunking terminal defines a key value 245 for the PTT key on the private network trunking terminal produced by itself, in step 101, the key value (245) is corresponding to the broadcast event containing the PTT key name.
Also, the specific broadcast event corresponding to the key value may be one or more.
Step 102: when a group call key event is detected, broadcasting an event corresponding to the key value of the group call key in an Intent mode.
In one embodiment, when there is one broadcast event, the broadcast event further needs to carry the status of the group call key (e.g., whether it is pressed or released). At this time, the name of the group call key corresponding to the key value and the state of the group call key are broadcasted using an Intent method.
In one embodiment, when the broadcast events are two, one of the broadcast events is used for broadcasting a key press event of a key corresponding to a key value, and the other broadcast event is used for broadcasting a key release event of a key corresponding to a key value.
By way of example, Intent broadcasts are defined as follows:
(1) PTT KEY press broadcast KEY _ PTT _ DOWN ═ lte.trunk.action.ptt _ KEY _ DOWN ";
(2) PTT KEY release broadcast KEY _ PTT _ UP is "lte.
The above exemplary description describes exemplary examples of defining broadcast events, and those skilled in the art will appreciate that such descriptions are exemplary only and are not intended to limit the scope of embodiments of the present invention.
The Intent mechanism is explained below. An Intent mechanism is provided in Android to assist interaction and communication among applications, Intent is responsible for describing actions, action related data and additional data of one operation in the applications, and an Android system is responsible for finding a corresponding component according to the description of the Intent, transmitting the Intent to a called component and completing calling of the component. Intent can be used not only between applications, but also for interactions between activities/services within applications. Therefore, Intent acts as a media intermediary, and specifically provides the related information of mutual calling of the components, thereby realizing the decoupling between the caller and the callee.
The expression form of Intent effect is: (1) the construction method is introduced into Component, the most common way is: (2) setComponent method; (3) the setClass/setClass name method. Explicit Intent can directly set the Activity class to be called through Component, can uniquely determine an Activity, and has a particularly clear intention, so the explicit Intent is explicit. The manner in which this Class is set may be a Class object (e.g., Class), or a string of package names plus Class names (e.g., "com. The Intent object roughly consists of 7 large attributes: action, Data, Category, Type, Component, Extra, Flag. The most common of which are the Action attribute and the Data attribute.
Step 103: and the group calling application registered with the broadcast event receives the broadcast event and determines the group calling key event based on the broadcast event.
In one embodiment, it is assumed that a corresponding relationship between a key value of a group call key of a private network cluster terminal and a single broadcast event including a name of the group call key and a state of the group call key is established in step 101. When the group call application receives the single broadcast event in step 103, a group call key event is determined based on the name of the group call key contained in the broadcast event and the state of the group call key.
For example, when the name of the group call key included in the broadcast event is a PTT key and the state of the group call key is pressed, the group call application determines that the group call key event is: the PTT button is pressed. The group call application may then initiate a talk in the PTT group call service in response to the event that the PTT button is pressed.
For another example, when the name of the group call key included in the broadcast event is a PTT key and the state is that the group call key is released, the group call application determines that the group call key event is: the PTT button is released. The group call application may then exit speaking in the PTT group call service in response to the event that the PTT button is released.
In one embodiment, it is assumed that a corresponding relationship between a key value of a group call key of a private network cluster terminal and a first broadcast event and a second broadcast event is established in step 101, where the first broadcast event is used for broadcasting a key press event, and the second broadcast event is used for broadcasting a key release event. Wherein: when the group call application receives the first broadcast event in step 103, determining a group call key event based on the name of the group call key included in the first broadcast event and the category of the first broadcast event; when the group call application receives the second broadcast event in step 103, the group call key event is determined based on the name of the group call key included in the second broadcast event and the category of the second broadcast event. Wherein, the category of the broadcast event is preset in the group call application.
For example, after receiving the first broadcast event, the group call application determines that the key is pressed based on the category of the first broadcast event, and when finding that the name of the group call key included in the first broadcast event is a PTT key, the group call application determines that the group call key event is: the PTT button is pressed. The group call application may then initiate a talk in the PTT group call service in response to the event that the PTT button is pressed.
For another example, after receiving the second broadcast event, the group call application determines that the key is released based on the category of the second broadcast event, and finds that the name of the group call key included in the second broadcast event is a PTT key, the group call application determines that the group call key event is: the PTT button is released. The group call application may then exit speaking in the PTT group call service in response to the event that the PTT button is released.
In one embodiment, the permission level of the broadcast event is further set in step 101; after determining the group call key event based on the broadcast event in step 103, further determining whether the permission level of the group call application is higher than the permission level of the broadcast event, if so, executing the group call action corresponding to the group call key event, and if not, exiting the process of the method.
For example, when the authority level of the broadcast event is set to Dangerous (Dangerous) and the authority level of the group call application is normal (normal) in step 101, the authority level of the group call application is lower than that of the broadcast event, so the group call application does not perform the group call action.
For another example, when the permission level of the broadcast event is set to be dangerous in step 101 and the permission level of the group call application is also dangerous, the permission level of the group call application is equal to the permission level of the broadcast event, so the group call application performs the group call action.
The following is an exemplary example of setting the privilege level of the broadcast event to dangerous: name ═ lte.
android:protectionLevel＝"dangerous"/>。
It can be seen that, after the embodiment of the present invention is applied, although specific extended keys (such as a group call key PTT key and an emergency call key SOS) of each private network cluster terminal provided by a plurality of device providers have inconsistent key value definitions, these keys can be uniformly converted into standard Intent events, so that the group call service flows on each terminal can be unified.
The embodiment of the invention also provides a device for determining the group call key event of the private network cluster terminal.
