Mobile phone talkback business adapter, mobile phone talkback business terminal and mobile phone talkback method

Abstract

The embodiment of the invention discloses a mobile phone talkback business adapter, a mobile phone talkback business terminal and a mobile phone talkback method. The mobile phone talkback business adapter comprises a PTT button processing unit, an SOS button processing unit, a display processing unit, a loudspeaker, a microphone processing unit, a PoC protocol stack unit, a voice encoder, an RTP protocol stack unit and a first underlying interface unit. The voice encoder is used for encoding the received media data and decoding the received encoded media data. The RTP protocol stack unit is used for packaging and de-packaging media data and media stream transmitted by the voice encoder and the first underlying interface unit respectively and then and then transmitting the media data and the media stream to the opposite side. The PoC protocol stack unit is used for generating calling PoC signaling to be transmitted to the first underlying interface unit and notifying the RTP protocol stack unit to receive the media stream after the calling PoC signaling is received. The mobile phone talkback business adapter is provided to the physical channel of a mobile phone terminal by the first underlying interface unit. Mobile phone talkback business cost can be reduced by the mobile phone talkback business adapter, the mobile phone talkback business terminal and the mobile phone talkback method.

Description

technical field [0001] The invention relates to communication technology, in particular to a mobile phone intercom service adapter, a mobile phone intercom service terminal and a mobile phone intercom method. Background technique [0002] At present, the PTT Over Cellular (PoC) technology in the mobile phone intercom technology carried by the public mobile network (referred to as: public network) has the advantages of large coverage, low networking cost and high degree of informatization. , has achieved a large number of applications and has become a new trend in the development of intercom technology. [0003] In the process of realizing the present invention, the inventor finds that the existing mobile phone intercom technology has at least the following problems: [0004] The mobile phone intercom technology requires the intercom service to be implemented on the mobile terminal. Since the usage habits of ordinary intercom service terminal users are quite different from ...

AI Technical Summary

Problems solved by technology

Since the usage habits of ordinary intercom service terminal users are quite different from those of ordinary mobile phone terminal users, intercom services and mobile communication services have different requirements for terminals at the hardware and software levels. If PoC intercom is to be implemented on mobile terminals For business, it is necessary to modify the mobile terminal. The customization requirements for mobile terminals are relatively high, including customization at the software level and customization at the hardware level. Among them, the customization at the software level requires, for example, that the mobile terminal supports the communication protocol, and the customization at the hardware level For example, it is necessary to set a push-to-talk (PTT) button, an emergency signal (SOS) button, and modify the speaker volume on the mobile terminal, which will result in a relatively large amount of modification of the mobile terminal. They have to be modified separately, and the cost is very high. As a result, there are few styles and high prices of mobile terminals supporting PoC on the market, and the performance consumption of mobile terminals after transformation is relatively large.
