Problems solved by technology

[0007] At the same time, in the current half-duplex walkie-talkie communication system, the speaking right switching between terminals is through the way of button grabbing, and the speaking terminal and the receiving terminal cannot negotiate the speaking right, and do not know some requests of the receiving terminal.

Embodiment Construction

[0031] In another Chinese patent application, the inventor proposed a mobile terminal with walkie-talkie function, which can realize the walkie-talkie function in the existing GSM / CDMA mobile terminal without adding any additional hardware. Based on intercom communication. In the present invention, a method for switching the speaking right on such a mobile terminal with an intercom function is proposed, through which the called terminal can request the talking right from the calling terminal.

[0032] GSM is used as an example to describe in detail. For mobile terminals of other standards, there are similar methods, which will not be described in detail. The GSM system has a complete method for synchronizing the network and the terminal and establishing communication, and also has a complete method for voice coding, voice transmission, and signaling transmission. The present invention fully follows the signal format of GSM, so that two GSM mobile terminals can directly commun...

Abstract

The invention discloses a method for switching speaking right in a mobile terminal talkback communication, which comprises the following steps that: when a called terminal needs to speak, the called terminal sends a request signaling on a subframe of a feedback signaling; a calling terminal receives the request signaling and sends a speaking right switching signaling on a subframe of a service channel; and the called terminal receives the speaking right switching signaling to finish the switching of the speaking right. The method ensures that a half-duplex talkback communication system betweenGSM mobile terminals works reliably, the speaking right is switched fairly, and the calling terminal is switched smoothly.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for switching the speaking right in the intercom service by using an ordinary mobile terminal. Background technique [0002] The wireless walkie-talkie has the advantage of directly realizing communication between terminals without network support. At the same time, with the development of wireless communication networks, mobile terminals have become an indispensable necessity in daily life. However, in some special cases, people hope to use mobile terminals to realize direct communication between terminals, but there is no network support. , this need cannot be met. In earthquake disasters, communication networks such as mobile phones are destroyed. In this case, professional equipment such as satellite phones or walkie-talkies are generally used now, but these equipment are generally inaccessible to ordinary people, making it impossible for trapped people to call...
