PoC (based on the PTT of cellular system) business is meant that in system the user side of only obtain the floor (Floor) can be made a speech, and other user sides can not be made a speech, and can only answer information.The PTT here is the putting call through immediately after connection technology.
The notion of PoC is that occupation mode and intercom are similar by the intercom development, and its characteristics are simple to operate, quick, and communication mode is half-duplex.
Described putting call through immediately after connection is meant user side by preestablishing talk group, need not dialing during conversation, pins specific keys and just can simultaneously speech be sent to members whole in the group, and button says that promptly calling and conversation connection procedure were finished in moment.The recipient need not any response and just can answer, and communication process adopts semiduplex mode, and a side is when speaking, and other members can only answer mute.
Described PoC service is a kind of of IMS (IP Multimedia Subsystem) business, and the IMS business here is a kind of service basic network that is based upon on packet-switched domain (Packet Switched) basis.IMS uses SIP (Session initiation Protocol) as main business control signaling agreement, and uses various application servers (Application Sever), can increase substantially the opening of IMS system like this, makes IMS that abundant business can be provided.
Described Session Initiation Protocol is a kind of text based general packet territory call control protocol, has simple, readability, easily expansion, characteristic end to end.Session Initiation Protocol is based on client/server (Client/Server) model, user side agent client (UAC) wherein and user side acting server (UAS) are based on affairs, in a dialogue, a UA may carry out the role of UAC, the role who carries out UAS in other affairs affairs.
The set of SIP request and its response constitutes affairs.The response of SIP all has an answer code sign, as 100/180/200/400, adds a response implication description character string, and be illustrated as " trying " as 100 responses is called " 100trying " response.
The SIP request is by its method (Method) name sign, as " INVITE ", " BYE ", " CANCEL ", " REGISTER ", " ACK " etc.Every kind of request all has different purposes, and as INVITE user side initiation session, BYE is used to discharge session, and REGISTER is used for the IP address of user side agency to current its use of SIP network registry.
SIP uses the coded format of unified resource sign (URI) as its protocol address, is called " SIPURI ", as " sip:lavi@huawei.com ".The various entities of SIP (comprising user side and various Server) all use SIP URI to identify, and use DNS SRV (IETF RFC2782) to realize that SIPURI arrives the parsing of concrete IP interface address.

More specifically say, the present invention utilizes the characteristics that PoC combines with presence service in IMS, the OMA PoC framework, the PoC server is retrieved as the current network type that user side provides service by presence service, and derives the maximum transmitted ability of current network according to the type of current network.Described presenting, (Presence) business was the business of information such as a kind of position that is used for showing transmission network various device, device, communication capacity, operating state.
After the network that service is provided for user side switches, the PoC server detects the transmittability of current network, if find that network capacity changes, then the PoC server is adjusted media stream service, and the concrete way of its adjustment is by suspending/resuming (HOLD/RESUME) operation of PoC Server initiation PoC service the transmission state of some Media Stream to be controlled.
For the adjustment of media flow transmission state is that transmittability according to current network decides.
In whole communication network, simultaneously the operation but the different subnetwork type of type mainly comprises 2.5G network and 3G network at present, along with development of internet technology, net type compatible in the whole network may increase to some extent, but for the consideration of the practicality and the compatibility between diverse network of technology itself, Yun Ying network type can't be too many simultaneously.
Because the transmittability of every type of network all is known, the type that therefore only need obtain this network just can be known the transmittability of this network.
Network capacity after switching changes, and the present invention need guarantee that user side can carry out media stream service the most efficiently under the restriction of current network transmittability.
The most efficient described transmittability that is meant server according to current network according to the basic condition of user side actual demand, at first satisfies the requirement of the most basic media stream service of user side to bandwidth.
After can realizing the most basic business demand of user side, the business that needs for user side provides bandwidth as much as possible, if the transmission bandwidth of current network is enough big, then carries out whole media stream services.
