Description
Technical Field
The invention relates to the field of mobile communication, in particular to a converged talkback terminal based on an intelligent shoulder microphone and application thereof.
Background
The shoulder microphone is used as audio/video accessory equipment of the interphone, the connection between the shoulder microphone and the interphone can be wired connection or wireless connection, the connection mode comprises Bluetooth and the like, and the reference is made to the attached drawing 1.
After the shoulder microphone is connected with the interphone, a user can realize talkback by hanging the shoulder microphone on the shoulder without holding the interphone by hand, and the group calling talkback can be initiated by receiving the group calling talkback and pressing the PTT key of the shoulder microphone, so that the use of an executive person who goes out is facilitated.
The intercom in the present application refers to a trunking intercom terminal based on a wireless private trunking network (wireless private network) if not specifically stated.
When the terminals work in a trunking talkback mode (non-direct mode), the terminals depend on the coverage condition of a registered wireless special trunking network, and if the network coverage is weak or is a coverage blind area, the interphone cannot realize trunking services.
At present, some trunking interphones based on a wireless broadband public network (such as 4G/5G networks of three operators) exist in the market, and trunking services of the trunking interphones are borne on the wireless broadband public network; because the network coverage rate of the wireless broadband public network is far better than that of the wireless private network, the use range/geographical range of the wireless public network interphone is far larger than that of the private network interphone.
However, compared with a private network interphone, the public network interphone has the obvious disadvantage that the public network interphone does not support the mission-critical communication: for the current wireless broadband public network, the bearer type of the trunking talkback service is Non-GBR (Non-Guaranteed Bit Rate), and its QCI (qos Class identifier) is not different from the ordinary packet data service (such as browsing web page), and is lower in priority than the QCI of the GBR (Guaranteed Bit Rate) Class bearer.
The allocation strategy of the wireless broadband public network on the air interface resources is to preferentially meet the service requirement of GBR class, and other Non-GBR class services share the residual bandwidth according to a certain resource allocation algorithm; the algorithm generally considers certain fairness, so that the trunking talkback service does not share special treatment of ensuring bandwidth as other common mobile internet APP services in the resource allocation of wireless bandwidth. Therefore, under the condition that the air interface resources are abundant, the trunking talkback service can be normally used; however, if the air interface resources on the network side are relatively tight, or the terminal side has more important GBR services to be performed (for example, answering a call or initiating a telephone call), the cluster talkback service is affected under these conditions, which causes the cluster talkback service to be interrupted or not performed.
In summary, the above problems do not exist for the wireless private network, because for the wireless private network, the trunking talkback is the most important service, and the private network is dedicated, and all air interface resources/spectrum resources preferentially ensure trunking talkback; in addition, the capacity of the private wireless network is designed by planning in advance, and the capacity of a wireless channel of each area is calculated and has a margin, so that the phenomenon that a cluster talkback call is not communicated can be basically avoided.
Therefore, in many fields of industry, the talkback based on the wireless private network still has an absolute dominance, and the mission-critical communication mission is carried out.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a fusion talkback terminal based on an intelligent shoulder microphone and application thereof.
Table 1 compares the merits of the two talkbacks as follows:

The judgment basis of the working state of the interphone is as follows:
(1) acquiring the Signal receiving Strength (RSSI) of a wireless private network measured by an interphone and the network registration status (registration status) of the interphone;
(2) if the RSSI is lower than a predetermined threshold (e.g., -90dBm, the specific value can be configured and adjusted according to the actual situation) or the registration status is 0 or other values indicating that the registration status is abnormal (please refer to the technical manual of the terminal manufacturer in the specific implementation), the status of the intercom is considered as an abnormal working status; otherwise, it is in normal state.
An application of the terminal, the application steps are as follows:

s5 routes PTT control information and audio/video input to the wireless public network cluster talkback module in the shoulder microphone, and routes the audio/video output of the wireless public network cluster talkback module to the audio/video output device of the shoulder microphone.
The cluster talkback talk group of the wireless broadband public network and the talk group of the wireless private network can realize fusion intercommunication on the network level, so the group talk back of the public network cluster talkback module in the intelligent shoulder microphone can be intercommunicated with the talk group where the interphone is positioned, the cluster talkback module of the wireless broadband public network transmits audio/video data to a background Server of a self system, the Server is responsible for forwarding the audio/video data to a corresponding wireless private network system in real time, the wireless private network system performs multicast to a self cluster terminal through an air interface after receiving the audio/video data, and then intercommunication between the public network cluster talkback talk group and the private network talk group is realized, and the intercommunication belongs to intercommunication between the system levels.
In the prior art (for example, chinese patent application with publication number CN 102547602 a), the shoulder microphone can implement three-way communication between the wireless public network and the wireless private network, and the problems and the implementation principles solved by the shoulder microphone are completely different from the present application, and the specific differences are as follows:
(1) the purpose of the above patent is that the shoulder microphone can simultaneously make voice communication with other people through a wireless public network and a wireless private network, namely, alleged three-party communication; the specific implementation principle is that when the fact that the shoulder microphone PTT key is pressed down is monitored, the control switch is simultaneously connected with the wireless public network communication module and the wireless private network communication module; when the fact that the PTT key of the shoulder microphone is released is monitored, the control switch connects the voice output of the wireless public network communication module and the voice output of the wireless private network communication module to the voice output device of the shoulder microphone.
