PoC is a kind of half-duplex, instant, multi-party communication mode, allows user and one or more user to communicate.Use this professional user and certain user's communication or be broadcast to the participant of a group.After the recipient receives this spoken voice; Can have no action (for example not replying this calling), perhaps before hearing transmit leg sound, notified and necessary this calling of reception; After this initial speech was accomplished, other participants can respond this speech message.
Simultaneously, along with the continuous development of technology, to standard formulation also in continuous improvement.And in the prior art; Often stipulated the specification requirement of back compatible property; Be the function that the communication equipment terminal of later stage version must comprise version communication equipment terminal in early stage, early stage version terminal equipment can be in the network that the network equipment of later stage version is formed operate as normal and the function of using the version in early stage; And the function at later stage version terminal and characteristic do not require and can use in the network that early stage, version equipment was formed.
For example; At present; Open Mobile Alliance (OMA) has defined PoC1.0 standard and PoC2.0 standard; The PoC1.0 standard of OMA all defines and requirement from many aspects such as traffic performance, business demand, business realizing, network frame, operation demand, agreement support, signaling control, medium controls, be the fairly perfect traffic criteria of a cover, but it also has certain limitation under some applicable cases; Such as PoC1.0 has only defined voice class PTT business, and all also has weak point aspect the PTT of multimedia mode business, intervention schedule and the performance requirement.OMA has formulated the PoC2.0 standard at present, solves the deficiency that PoC1.0 exists, and functions such as preemption is preferential, dealing with calamity, speech case, speech multicast also are provided simultaneously.The formulation of the PoC2.0 standard of OMA will have more importantly meaning to the development of PoC service.
Defined at OMA PoC2.0 and can preserve the memory function PoC Box (comprising UE PoC Box and NW PoC Box) of session control data and session service data for the user; But in the business norms of PoC1.0 version, do not define the traffic performance of memory function.According to the basic demand of back compatible property, the signaling information of PoC Box can't be discerned in PoC1.0 version terminal, can not use the PoC Box function that provides in the PoC2.0 network.For the user; PoC2.0 user's PoC Box function is to preserve session data that PoC1.0 user sends; Therefore the terminal of the PoC1.0 function that can't use PoC Box to provide can't realize the terminal of PoC1.0 version and the communication between the PoC Box.
Again for example, in multimedia conference system, existing multimedia terminal is inserted in the multimedia conference system newly developed, the situation that the original multimedia terminal of characteristic that can occur increasing newly and function can't be used.In this case, the signaling of multimedia conference system newly developed will have at least the original multimedia terminal of partial information to discern, and this makes that also there is certain obstacle in communication between the terminal.
