Description

The method of in next generation network, managing business, device and next generation network

Technical field

(Next Generation Network, NGN) technology relate in particular to business treatment technique and relevant communicator at next generation network to the present invention relates to next generation network.

Background technology

NGN is based on the network of grouping, and telecommunication service can be provided.NGN utilizes multiple broadband ability and service quality (QoS) to guarantee the transmission of data, and its professional correlation function is independent mutually with its tranmission techniques.In addition, NGN can make the user freely be linked into different service providers, and supports universal mobility.

(Service-Oriented Architecture SOA) is the set of service to the framework of service-oriented.Communicate with one another between service, this communication may be that simple data transmit, and also may be that two or more service coordinations carry out some activity.Need some method to connect between service.It is exactly explication that what is called is served, it is perfect to encapsulate, be independent of the function that other serve environment of living in and state.

SOA is not a kind of ready-made technology, but the method for a kind of framework and organization foundation structure and business function.SOA is a kind of design, exploitation in computing environment, disposes and manage the model of discrete logic units (service).In the system based on the SOA framework, the function of concrete application program is to be made up by some loose couplings and assembly (just serving service) combination with unified interface definition mode.One all is encapsulated in some functional modules based on all program functions in the system of SOA framework, utilize these packaged functional module assemblings to make up needed program or system, and these functional modules are exactly the different service (services) in the SOA framework.The framework model of SOA as shown in Figure 1.

IP Multimedia System (IP Multimedia Subsystem, IMS) be the subsystem that 3GPP introduces on packet network, adopt the bearer path of packet domain for its control signaling and media delivery, introduce Session initiation Protocol (Session Initiation Protocol, SIP) as professional control protocol, by business control is separated with carrying control, provide the multimedia realtime communication business.Main functional entity comprises controlling call entity CSCF, the home subscriber server HSS of centralized management user contracting data of functions such as control user registration, session control among the IMS, and the application server AS of miscellaneous service logic control function is provided.

At present to the research of NGN all based on IMS, along with the NGN framework of ETSI TISPAN is considered aspect contents such as more user network, access, core network and intercommunication on the IMS basis, and along with deployment with the IMS network, IMS, NGN, circuit commutative field (CS Domain), the internet service network coexisted situations of multiple business such as (Internet Service) will appear in whole network, the feature of IMS will absorb more service deployment comes in, and finally replaces the circuit switching (CS) network.

In the IMS network architecture; the valued added applications service that provides all non-basic sessions to continue class for IMS user; all in the AS entity, provide; the CSCF of session control layer is the business triggering route of basic IMS SIP session to the AS of each different value-added service logics of operation; and functions such as the registration that can share of all valued added applications, fail safe protection, QoS control, basic session route provide a common platform, guarantee that the design that each AS supplier only needs to pay close attention to value-added service logic itself gets final product.

Application server AS is by mutual based on ISC interface and the S-CSCF of SIP, S-CSCF is according to the sip message territory content that triggers subscription data and current input based on every user's AS business, the rule match of contracting, and proceed to the route of each AS according to matching result.For a designated user and S-CSCF thereof, special setting according to its AS triggering rule, not only support different business to arrive the triggering of different AS, can realize the repeatedly triggering of same session simultaneously, thereby realize associative combination same user's value-added service logic to a plurality of AS.

Three kinds of professional open modes that IMS provides are as follows:

Sip application server: be the place that the SIP service logic loads and carries out.Can there be SCIM (servicecapability interaction manager) to coordinate various application servers and finishes a concrete application.

IM-SSF: be a kind of special application server, its detects the Service Point Trigger of CAMEL regulation, finish and SCP between CAMEL Application Part adaptive.The intercommunication that can realize SIP and INAP/CAP inserts traditional SCP and thinks that IMS user provides Circuit Switching Network's intelligent network original value-added service.

OSA SCS: be the unified professional open model that 3GPP formulates based on Parlay API, for third party's application server provides abilities open and use Internet resources safety.

Present IMS network has the following disadvantages:

(1), different business is different to the requirement of session ability, the ability of a S-CSCF can not be supported all signing service of user.For example: user contracted simultaneously telephone service and IPTV business, the characteristics of telephone service are that the duration is short, press duration and charge, and the IPTV business features is online for a long time, pay-per-use or monthly payment charging.If a large amount of users uses the IPTV business simultaneously, the S-CSCF that will cause the user to be assigned with does not have resource and ability that telephone service is provided.

(2), the open ISC interface scarce capacity of the business of IMS, can't satisfy the demand of complicated business control.For example, initial filter criteria depends on the sip request message content, because the uncertainty of business interface has caused same sip message content need trigger different business.For example, the INVITE request triggers the professional and Telephony business of IPCentrex.And for example, a plurality of initial filter criteria are that serial triggers.If AS is a B2BUA, its follow-up AS that is triggered causes interdepending and chain upgrading between the service deployment AS to its demand that message content transparent transmission is arranged.For example, the INVITE request successively is triggered to TelephonyAS and Conference AS, and Conference AS requires Telephony AS to be supported in transparent transmission in the Contact header field " isfocus " parameter.

(3), IMS supports that the outward service open ability is imperfect.IMS only supports by Parlay API the open third party of giving of IMS network capabilities.On the one hand, Parlay API ability mainly is open traditional telephone service and messaging service, and professional ability is limited; On the other hand, the IMS network lacks the interface of integrated third party's business, and does not support the issue and the visit of teleservice ability.

(4), the IMS network architecture is too complicated.The IMS network only defines logical architecture, do not consider physical structure, and industry is also not the same to the understanding of physical structure.For example: the 3GPP billing function relates to functional entity and comprises: CDF, CGF, CCF, IM-GW, OCS etc.; Interworking function entity comprises: IBCF, IWF, Transit, MGCF, BGCF etc., and syntagmatic is difficult to determine that networking is also very complicated; And the IMS network causes interface always many based on the functional entity defining interface, and flow process is various, and standard is made slow progress, and the development amount is huge, the interoperability test complexity; Functions such as physical NE corresponding characteristics such as charging, performance, monitoring are difficult for determining that exploitativeness is poor.

Because above-mentioned deficiency causes the fusion difficulty of existing IMS network and other networks, can not support other business flexibly.
