Description
Technical field
The present invention relates to mobile communication technology, particularly relate to a kind of realization of Communication method.
Background technology
Press-and-talk business is a kind of of trunking communication, refers to direct-connected " point-to-point " and " putting multiple spot " voice communication service in real time, also can be described as PoC (Push to talk over Cellular) business.Press-and-talk business uses the half-duplex operation mode, promptly only allow people's speech at one time, and other people can only receive this teller's voice messaging.Use press-and-talk business, the calling party only needs to need not to dial by a button and wait for that the other side's off-hook just can other member in group make a call, the phone demand working, set up particular talk group rapidly, be convenient to very much between team, working group and other colony collaborative work with exchange, therefore, obtained using widely.
At present, press-and-talk business support " media transmission application queue function " that is to say, cluster server is provided with media transmission application queue in (or being called the PoC server).When cluster server receives medium that a plurality of users in the group (user carries out PoC communication by the PoC client) send when sending request simultaneously, the medium of only ratifying one of them user send request, allow this user to send medium, other user's receiving media information, and other received user medium are sent request be distributed in the media transmission application queue; Perhaps, a user in group is when sending media information, if cluster server receives the medium that other user sends in this group and sends when asking, also other received user medium can be sent request and be kept in the media transmission application queue.Like this, after active user's medium send end, each medium that cluster server is preserved from media transmission application queue send selects medium to send request in the request, and authorize selected medium transmission with medium sending right and ask corresponding user, carry out medium by this user and send, begin new medium and send and receiving course.
The above-mentioned medium of mentioning can be voice, video, and picture, all kinds of media formats such as literal are typically voice.Therefore if during PoC system support voice, " media transmission application queue " can be called " speaking request formation " again, " medium send request " can be called " speaking request ", and " medium sending right " can be called " right to speak ".
