Description

Video ads implementation method, server platform and client based on IMS

Technical field

The present invention relates to communication technical field, more specifically to a kind of video ads service implementation method, server platform and client based on IMS.

Background technology

(IP Multimedia Subsystem is the open platform of unified supporting to be provided by what third generation gpp tissue (3GPP) proposed for mobile multi-media service IMS) to IP Multimedia System.IMS adopts packet domain for it provides bearer path of controlling signaling and media delivery, is the new core network domain of the all-IP framework that is made up of many new functional entity network elements.(Session Initiation Protocol is SIP) as its professional control protocol for the initial session protocol that IMS adopts RFC to define.Wherein, SIP is based on the application layer protocol of text, characteristics simple in structure, that autgmentability is strong, media combination is convenient and network compatibility is good that this agreement has.

Professional control separates with service logic among the IMS; The core network element of the IMS business of seeking unity of action is controlled; Provide support unified route, authentication, charging and the trigger mechanism of various mobile multi-media services; Then (Application Server AS) realizes abundant multimedia service logic by application server.The core network element of IMS comprises proxy call conversation control function entity (P-CSCF), query call conversation control function entity (I-CSCF), service call session control function entity (S-CSCF), home subscriber server (HSS) etc.P-CSCF is IMS terminal use's an IMS ingress for service point; Can be positioned at home network (Home Network) or visited network (Visited Network) according to user's current location, carry out bearing resource authentication, service quality (QoS) management and charge and search corresponding I-CSCF for the user.I-CSCF and S-CSCF are positioned at home network, and I-CSCF hides the network topology of home network, and specify S-CSCF through HSS for the user.

S-CSCF carries out user conversation control and service management, in user's registration, carries out the registrar function.In the IMS network, carry out user's business control and registration, promptly when the user roams, be responsible for its professional control and register by the S-CSCF of its home network by home network.

S-CSCF to the management of customer service based on mutual and initial filter standard or norm (Initial Filter Criteria, the iFC) mechanism of HSS.HSS is an integrated database, and is mutual through Cx interface and S-CSCF, and the HSS storage comprises the user signing contract information of iFC, and S-CSCF then accomplishes service trigger based on iFC.After accomplishing user's registration; S-CSCF is from HSS download user CAMEL-Subscription-Information; These information comprise one or more business descriptions (Service Profile), and business description comprises public identify, core net service authorization, shares inceptive filtering rule set (Shared iFC Set), initial filter criteria (iFC) etc.IFC has represented the order configuration data of a kind of user to service application, and the information that it comprises has: and the priority of triggering rule, trigger point (Trigger Point, TP), the AS sign/address, default process, the optional information on services that are triggered.Each AS has the trigger condition of oneself among the IMS, and whether TP decision is forwarded to application server with application layer messages, it comprise one or more service trigger device instances ((Service Point Trigger, SPT).After S-CSCF receives sip message; According to the method (SIP Method) of message, request unified resource sign (Requested-URI), message header (SIP Header), message body content and their the various combination conditions of message; Mate with the SPT among the iFC; Then be toggled to corresponding AS if meet, do not meet and then carry out default process.

The user is realized by S-CSCF in the registration of IMS network; S-CSCF is based on associated safety parameter of obtaining from HSS and IP multimedia pUblic identity (Public User Identity; PUI) with the corresponding relation of IP multimedia private identity (Private User Identity); PUI is carried out authentication, realize the registration of PUI, accomplish the title/address information binding that is used for PUI is carried out addressing simultaneously at the IMS network.If S-CSCF is when receiving a registration message, there is the third party AS of coupling iFC, then accomplish and transmit this message behind the IMS network registry and carry out third-party registration to third party AS.

AS accomplishes the execution of service logic and provides among the IMS.AS and S-CSCF are through IMS service control (the IP Multimedia Subsystem Service Control based on Session Initiation Protocol; ISC) mutual; Wherein AS can be divided into sip application server (SIP AS), IP Multimedia System Service Switching Function server (IP Multimedia Subsystem-Service Switching Function; IM-SSF) and open service access-service capability server (Open Service Access-Service Capability Server, OSA-SCS) three types.

SIP is the application layer protocol that is suitable for controlling multimedia communication on the IP network; Can be used to create, revise and session that one or more participants that terminate participate in; And can dialogue-based description agreement (Session Description Protocol SDP) provides the negotiation of terminal communication ability.The realization of Session Initiation Protocol function is made up of a series of Session Initiation Protocol methods (SIP Method), corresponding each SIP Method, and Session Initiation Protocol message is divided for request message that is sent by the user end to server end and the response message that is sent to client by server end.In the Session Initiation Protocol, registration (Register) request message and response thereof are used for registered user's identity and positional information; Customization (Subscribe) request message is used to customize the generation of certain incident; Notice (Notify) request message is used to notify the generation of customization incident.

The mobile video advertising business is the combination of mobile communication business and advertising business, and is net loaded through mobile communication, makes mobile phone users receiver, video advertising film whenever and wherever possible, obtains abundant content information.The business model of present mobile video advertisement mainly adopts film source integration mode and terminal preset mode.The film source integration mode is the video ads short-movie to be edited in advance or switched in the advertising service platform side to insert in the video frequency program that the user watches, like the Lightningcast ad system; The terminal preset mode presets advertisement applications client small routine at portable terminal, and downloaded stored is at portable terminal in advance in the video ads short-movie, and (when being in idle condition like the terminal) playing video advertisement when being in some particular state at the terminal is like Ad MOA ad system.The drawback of these two kinds of patterns is that the user is the passive ad content of accepting, and the video ads that transmits or download is not selected based on terminal use's actual individual demand; The effective mechanism that lacks feedback terminal user advertising behaviour in service; Shortage is upgraded the effective mechanism of video ads information to the terminal use.

Present mobile video advertising business does not also have ripe unified flow process and agreement, realizes with proprietary protocol and method basically.Aspect the standardization that realizes moving advertising, open moving used alliance (Open Mobile Alliance OMA) proposed framework suggestion like accompanying drawing 1.Moving advertising server platform (Ad Server) is the advertising business functional entity of network side, and functions such as statistical analysis, user/Service Data Management are used in the moving advertising selection, moving advertising transmission, the moving advertising that have to the user; The moving advertising engine of mobile terminal side (Ad Engine) has advertising inquiry and download, moving advertising selection, advertistics data processing, user/Service Data Management function.Ad Server and Ad Engine transmit moving advertising relevant information and moving advertising content respectively through two passages.It is the advertising business external entity of mobile terminal side that client-side ad is used (Ad App), and it is from Ad Engine request and obtain advertisement and represent to the terminal use; It is the external function entity of network side that the service provider uses (SP App), from Ad Server request with obtain advertisement and be embedded into its content that offers the user and go.Context and personalized resource entity (Contextualization and Personalization Resources) provide terminal use's relevant information (like user characteristics, interest preference, position etc.) to Ad Server and Ad Engine, is convenient to Ad Server and Ad Engine selects personalized advertisement targetedly for the user.

But the moving advertising framework of present OMA also is the framework of a demand property generally.For example; Although it notices that the importance for the customization personalized advertisement has proposed context and personalized resource entity demand; But because the diversity and the complexity in context and classification of personalized resource entity and source; OMA does not define definite context and personalized resource entity notion and relevant interface, does not provide practicable customized information presentation mode; The concrete advertising message that concrete communication protocol between Ad Server and Ad Engine maybe need be transmitted is clearly definition not; In addition, although the transmission OMA of Ad Engine ad content has advised drawing/pushing away the dual mode of (Pull/Push) and broadcasting (Broadcast) between Ad Server, do not provide the method for concrete realization.

IMS is as the unified and open platform that supports various flexible multimedia services; Its traffic signaling control method mainly concentrates on interactive multimedia communication service type at present; Like business such as voice, meeting and message; And in the IMS framework, also be not directed against video ads business realization method, if therefore can propose a kind of video ads business realization method, will greatly promote quick establishment and deployment that video ads is professional based on IMS.
