Description

A kind of charging method and system based on media transmission priority
Technical field
The present invention relates to Push to talk over Cellular (PoC) technology, be meant a kind of PoC charging method and system especially based on media transmission priority.
Background technology
Push to talk over Cellular (Push to Talk Over Cellular, PoC) business, be a kind of at (Push to Talk, PTT) business allow the user to set up by specific keys and communicate by letter immediately with other one or more users based on the PoC of cellular mobile communication networks.Wherein, the PTT business stem from trunking communicating technology, its user experience is similar to intercom.Carrying out of PoC service can be independent of the bottom bearer network, and makes full use of the bottom bearer network, and (Voiceover IP, VoIP) technology realizes the voice by the half-duplex internet protocol-based.
PoC service is the application of VoIP business in the mobile network, and the group call function of " one to one " and " one-to-many " can be provided flexibly.Fig. 1 is the traffic model schematic diagram of PoC service in the prior art.As shown in Figure 1, the real-time semiduplex voice communication that PoC service provides a kind of mode simply and easily to satisfy the user can realize functions such as point-to-point communication, point-to-multipoint delivery, instant user notification.
Fig. 2 is the logical architecture schematic diagram of PoC service system in the prior art.As shown in Figure 2, at square frame 200 interior sections is PoC internal system logic entity, comprising PoC client (PoCClient), PoC Control Server (Controlling PoC Server) and multiple PoC function executing entity (PoC enabler), the PoC Control Server is carried out the major function of PoC service, can be divided into control PoC function (Controlling PoC Function, CPF) and participate in PoC function (Participating PoCFunction, PPF), wherein, each PoC function executing entity only carries out alternately with the PoC Control Server, and described PoC function executing entity can comprise secure entity, charging entity, the Authentication Authorization entity, search registering entities etc.Be expansion entity (External entity) at empty frame exterior section, comprise presence server (Presence Server), XML document management server (XDMS), client's setting (Provisioning) etc.Wherein, presence server is used to receive and store the presentation information that all clients are announced, and presents on demand, also can be subscribed to by other entity, as information such as " whether online ", " interruption-frees "; The XML document management server then is used to manage PoC group and user profile.
In PoC 1.0, has only speech media type.Send at voice under the control of controlled entities (Talk BurstControl Entity), at one time in, have only a user to have right to speak, promptly voice send (Talk Burst) authority, and other session participating user is only answered authority.If system and terminal are all supported formation, all users' speaking request all will be arranged in the middle of the formation so.The division of priority if system and terminal are all supported to make a speech, so, user's speaking request will be according to different speaking request priority arrangement in formation, and wherein, speaking request can be divided into four priority:
1) preempting priority: PoC user's speaking request with preempting priority, cancelled right to speak with making current voice send the owner with right to speak, unless sending owner's voice transmission, current speech also has preempting priority.After the voice transmission was released or cancels, the participating user that has preempting priority and asked to make a speech was awarded the right to speak that is higher than other priority.
2) high level priority: when voice send when being released or cancelling, asked the participating user of making a speech and having high level priority, the participating user that should have precedence over normal priority is awarded the right to speak.
3) normal priority: when voice send when being released or cancelling, asked to make a speech and have the participating user of normal priority, only when not having the participating user request of higher priority, just be awarded the right to speak.
4) only answer priority: the participating user that has this priority only is allowed to answer, and the voice of this participating user send and will be rejected.
When user adding to conversation, the PoC Control Server is provided with a speech priority for each user, this priority is the limit priority that the user can use when asking to make a speech, in concrete session, then send the setting of priority by PoC user oneself decision voice, can be equal to or less than the PoC Control Server and authorize this user's limit priority, be arranged in the formation by the speaking request of PoC Control Server the user, wherein, when having the PoC client requests speech of equal priority, should arrange or floor grant by the time sequencing that receives request.
PoC2.0 is the highest version standard of formulating at present, expands and upgrades for PoC1.0, and the characteristic of comprehensive compatible PoC1.0, also support the half-duplex voice business.POC2.0 allows the user to set up the Multimedia session of communicating by letter immediately with other one or more users by specific keys, allow the user in session, to transmit multiple medium type, as still picture, live video stream, text and other files that need transmit etc.
Centralized control in a session is to realize by the omnidistance unique PoC Control Server (Controlling PoC Server) of session.For the control of different medium or associating medium, be to send controlled entity (Media Burst ControlEntity) by the medium that are associated with each medium type to realize.User's medium send (Media Burst) request, send at a certain medium under the control of controlled entity, at one time in, have only a participating user that the authority that sends this kind Media Stream is arranged.If PoC2.0 system and client are supported formation, and support the medium of different priorities to send, then medium send request and also send to the PoC Control Server, are that medium send request queue by the PoC Control Server again.
In present PoC standard, if PoC Control Server and terminal all support media send the function of priority, then when PoC user added PoC session, the PoC Control Server was just specified one or group media transmission priority for this user.This transmission media priority is that this user the highest operable medium send Request Priority, and it is relevant with this user's user profile, and also the factors such as Quality of experience (QoE) parameter value with carrier policy or active user are relevant.
Similarly, in the PoC2.0 business, medium send request and also are divided into four priority, promptly 3 grades, 2 grades, 1 grade and 0 grade, correspond respectively to preempting priority, high level priority, the normal priority among the POC1.0 and only answer priority.The media transmission priority that the PoC Control Server distributes for the user who adds session, it can be a media transmission priority that is provided with for all medium types, for example, for the media transmission priority of current initiate PoC user A appointment is 2 grades, expression sends for all types of medium, the limit priority of user A is 2 grades, the user can select to be equal to or less than 2 grades media transmission priority, if sending in the request at medium, the user do not have assigned priority, its priority of system default is 1 grade so, i.e. normal priority.
The PoC Control Server also can be set a group media for different medium types and send priority.For example, be 3 grades for the limit priority of voice, be 2 grades for the limit priority of video, for phonotape and videotape (Speech﹠amp; Image) limit priority of associating medium type is 1 grade.User A sends in the request at corresponding medium so, corresponding each medium send the priority of request, the priority of each medium type all should be less than or equal to the specified corresponding limit priority of PoC Control Server, will fail otherwise medium send request.Similarly, send request for the medium that do not carry Request Priority, system adopts the priority of acquiescence to it, promptly 1 grade.
In view of medium in the PoC2.0 business send the different priorities of asking, what at first consider in medium transmission request queue ordering is that medium send Request Priority, arranges according to the request time order for having identical media transmission priority then.This is a kind of difference for user's service in fact: the user that priority is high can obtain the medium sending right limit more earlier.
Different PoC users' media transmission priority may be different; The media transmission priority of same PoC user in different sessions also may be different; In same session, identical PoC user, for different medium types, its media transmission priority that adopts also may be different; In same session, if PoC service system support media send the function that priority is divided, and each PoC user may be different to the support of this function.
Angle from top service, the service quality that customer group in each group or the session is enjoyed is different, in order to embody this differentiated service better, in the PoC service charging process, need to consider that medium send Request Priority, charge and the foundation of differentiated service is provided as operator.And in the prior art, the charging policy that charging entity adopted is mainly set according to existing subscriber's information, do not consider that the user sends the professional media transmission priority that is had for dissimilar medium, therefore also do not have billing scheme at present based on different media transmission priorities.
