Description

A kind of cloud platform and method of work thereof of supporting the UNE business

Technical field

The present invention relates to a kind of cloud platform and method of work thereof of supporting the UNE business, belong to the technical field of UNE business support equipment and system thereof.

Background technology

Along with development of internet technology, the trend that three nets of telecommunications network, the Internet and Broadcasting Cable Network also present mutual fusion day by day and open up to each other.In UNE, service needed merges on the one hand, so that utilize the diverse network ability that a greater variety of new business are provided jointly better; Need also on the other hand more flexibly that business provides and operation way, so that new business is provided fast and efficiently.

At present, the third party service provider is to be disposed and safeguarded corresponding software and hardware operation system by service provider oneself usually, thereby has increased service provider's deployment and maintenance cost when the Disposition ﹠ Operation value-added service; Simultaneously, also increased the management difficulty of Virtual network operator for the service provider.

Under integration of three networks background, the operation of Network more and more is subjected to the favor of telecom operators.Yet traditional telecommunication application server does not provide the access ability of Internet resources to other business, and for example, it does not support Internet protocol, and this just makes towards the exploitation of the telecommunication service of UNE very difficult with operation.

The request load of telecommunication service is not stablized constant, but fluctuates up and down according to different time, is characterized in that the load of crest and trough differs bigger; And, the situation that load increases severely can appear under festivals or holidays or emergency case.Operator is the demand that satisfies telecommunication user, often comes network elements such as deployment server with the requirement of satisfying maximum load.Yet do the consequence that can cause two aspects like this: when the service request amount was at a low ebb, a large amount of servers were in idle state, made the human cost of many hardware and maintenance all waste.But when the subscriber traffic of special period increased severely, existing machine room, server-capabilities but still can not satisfy the demand of maximum load probably, and user's experience is still very poor.

The typical products of conventional telecommunications service supporting platform has: the mobile value-added service platform of future generation of general first EOS Northern Telecom business support system, Guangdong Telecom integrated service support system and IBM etc.Wherein,

General first EOS platform is the application software platform that is based upon on the J2EE basis, provides from the complete systematicness support of exploitation, debugging, operation, maintenance and management, has stronger secondary development ability.Each application system based on the Northern Telecom business support system of EOS all is based upon on the basis of using carrying platform, and the core part of using carrying platform is EAI platform, core data object and system management module.System adopts the hierarchy of presentation layer, Business Logic and data Layer.

Guangdong Telecom integrated service support system comprises 13 subsystems such as service handling, dispatching management, resource management, construction management, customer service management, toll administration, interface management, marketing management, the management of product, customer account management, system management, basic data management and statistical management, adopts the hierarchical system framework of public information management platform and interface platform layer, infrastructure service layer, business framework layer, service application layer.The public information that public information management platform definition IBSS system and other related systems are shared mainly provides customer account management, at present to satisfy the demand of each system to customer information; Interface platform provides the exchanging mechanism of system's outbound data, handles the data exchange agreement of IBSS and external system; The public service of infrastructure service layer define system, it doesn't matter for these services and Business Processing, all systems can handle such infrastructure service, as database access, name Service, public API (as the date/the character processing) etc.; The basic service framework of business framework layer define system, it is the basis that system business is realized, as rights management, the management of product etc.; Service application layer is the business realizing layer, and it realizes the concrete business of IBSS by the service of calling business framework, and it comprises the realization of each subsystem.Each subsystem of service application layer is separate, and by interface accessing, the Business Processing order between each subsystem, operation flow requirement are coordinated by business process system and controlled.

The smooth evolution scheme of IBM mobile value-added service platform and critical support technology thereof can realize that the perpendicular system that repeats from single, service detach and function is to the transition of supporting the horizontal business platform that across a network, function are unified; The business platform integrated framework of the harmonious work of an energy and Legacy System is provided, and a cover system scientific methods.It can carry out the assessment of ability maturity to existing disassociation service system of operator at new business demand, determines capacity gap and system integration pattern, helps design to generate new system architecture; Horizontal business platform provides the function of service channel integration, service logic layout and professional delivery management.

Though above-mentioned three typical telecommunication service support platform products can both satisfy the business support requirement of field of telecommunications, yet, from integration of three networks angle, these three platforms all only provide the support to telecommunication service, can not compatible Broadcasting Cable Network business and Internet service; Angle from platform capabilities, these three platforms do not possess the service provider that the cloud platform brought and rent the network equipment and dynamic retractility resource requirement as required, thereby improve the advantage of utilization rate of equipment and installations, still can not solve the problem that previously described field of telecommunications business support technology is run into.

Along with the develop rapidly of internet arena, the cloud computing technology rely on its on-demand service, flexibly can expansion, high reliability, lower-price characteristic, be subjected to the extensive concern of industry.The user who inserts " cloud " can obtain the computing capability more much higher than local resource, can also change the cloud computing ability of its order according to the actual requirements neatly.Because service beyond the clouds, and high in the clouds provides the high reliability guarantee, the user need not to carry out any attended operation in this locality, can significantly save the great amount of cost of hardware investment and maintenance.

The cloud platform, or be called platform and promptly serve (PaaS, Platform as a Service), provide one of service manner as cloud computing, can be considered to the core of whole cloud computing system, it provides the environment of exploitation, deployment and the operation of Internet service.Service developer can be engaged in the service distribution of oneself developing to debug and run to the enterprising industry of cloud platform, and in this process, platform provides professional needed all resources, and the user need not worry how to manage these resources fully.At present, cloud platform product comparative maturity has: the Google App Engine of Google, the Azure of Microsoft and the Hadoop of Apache etc.

Google App Engine essence is a platform of being made up of application server cluster, BigTable structural data distributed storage system and GFS data storage service, it provides one group of application programming interfaces to the developer, the developer uses Python or java programming language to write web application, and uses these interfaces to visit the services such as space, database storage, e-mail and memcache that Google provides in program.

Windows Azure Platform is a cloud computing platform that operates in data center of Microsoft, and it comprises the set of service that a cloud computing operating system and provide for the developer.This platform, the also service that can use this cloud computing platform to provide can either directly be provided in the application that the developer creates.Windows Azureplatform comprises Windows Azure, SQL Azure and Windows Azure platform AppFabric.

Hadoop has mainly realized thought and the MapReduce model of GFS, and as a software platform of increasing income, Hadoop makes that writing and move the application program of handling mass data is more prone to.Hadoop mainly comprises three parts: Hadoop distributed file system (HDFS), MapReduce realize and HBase (realization of Google Bigtable).HDFS carries out cutting with file according to the data block of setting size when the storage data, each piece is distributed in each node in the cluster.In order to guarantee reliability, HDFS can create a plurality of copies according to being configured to data block, and is positioned over the computing node of cluster respectively.MapReduce is divided into a plurality of little tasks with application and goes to carry out, and each little task is only handled the local data blocks stored of this computing node.

Though above several cloud platform product all respectively has its advantage,, they are all only towards Internet service, and this just makes its cloud computing that provides be difficult to be generalized to UNE.With the communication network in the UNE is example, and the bottleneck reason of analyzing its existence mainly is:

(1) from the procotol aspect, the Internet mainly adopts http protocol, and is fairly simple; Many and the more complicated of the communication protocol quantity of telecommunications network, and the definition of each agreement is different fully with HTTP.

(2) from the BlueDrama model, Internet service mainly is stateless non-conversational service; The telecommunications network business had both included the conversational service (for example calling class service) of state, also comprised non-conversational service (for example note class business).Because conversational service has state, its processing mode is more complicated more than non-conversational service.Cloud platform towards the Internet can not be supported the basic telecommunications agreement because of it, can not satisfy the maintenance needs of the distinctive call session of telecommunication service, therefore can not be applicable to communication network.

Other networks in the UNE also have similar situation.Therefore, existing various cloud platform and be not suitable for UNE.

Chinese patent application (CN200710002988.5) has proposed a kind of Universal Service Platform of the support multiple business based on many network integrations, this general service mainly comprises: the service access unit, be connected in the communication network of each Virtual network operator, be used to insert various communication services, the agreement support be provided and carry out data interaction with message processing unit; Message processing unit, the service request of the access unit of accepting business is judged the type of asking, and calls the srvice instance in the service enabler unit and receives the service order that the service enabler unit sends, and be forwarded to the service access unit; The service enabler unit is used for providing operation support to each communication service, carries out business according to the calling service request that message processing unit sends, and triggers new service request according to execution result, and will newly ask to be back to message processing unit; Administrative unit is connected to above-mentioned each unit, and finishes the coordinated management to it.Though the Universal Service Platform that this patent application provided can provide the multiple network access protocol, to support the different business of heterogeneous network operator; Yet it can not provide the cloud equipment leasing that platform is had, buy computational resource and dynamically change the ability of adjusting resource according to business load as required, can not solve the conventional telecommunications service supporting platform intrinsic shortcoming.

Referring to Fig. 7, introduce step 2, the cloud platform user is carried out user's registration, resource bid and new business and is loaded:

After platform starts, platform user must at first be registered to platform, insert essential information and buy resource needed, platform just can be created its exclusive virtual execution space for the user according to the resource quantity that the user orders, and is that its initial creation platform is carried out examples such as engine, load equalizer.This step comprises more interactive action, so illustrated with interactive form shown in Figure 7.

(21) user's enrollment page of providing of the service management unit of cloud platform user (comprising service provider or Virtual network operator) sign-on access platform management module is filled in user profile, finishes registration.

(22) platform user is finished the order-resource ability; According to own demand, order required various cloud platform resource abilities (comprising cpu resource, data storage resource and network bandwidth or the like) to the resource allocation scheduling unit of cloud platform.

(23) the resource allocation scheduling unit sends the professional space request of carrying out of creating to carrying out the space management module, carry out the space management module to the needed virtual resource of platform resource manager application platform user, and on this resource base, create professional space and the professional virtual machine instance of carrying out in the space carried out.

(24) carry out the space management module and send the virtual machine file backup request to the platform resource manager, the platform resource manager carries out schedule backup with synchronously according to the redundancy backup strategy; So far, the cloud platform is finished the operation of platform user resource ordering.

(25) Service Management Unit of platform user access platform administration module is uploaded the business that will be deployed in the cloud platform; Service Management Unit sends professional load request to carrying out the space management module.

(26) carry out the professional load request of space management module responds, create the business of respective numbers and carry out engine instance, loaded with traffic is also returned the loading success response.

Referring to Fig. 8, after introducing the cloud platform and finishing professional the loading,, carry out professional associative operation and dynamically adjust and rent resource according to the platform user instruction.This step comprises following content of operation:

(31) after the cloud platform is finished professional the loading, according to the instruction that the service life cycle management interface of platform user by Service Management Unit sends, the operation of carrying out activation of service, deexcitation or rolling off the production line.

(32) service operation is after a period of time, if platform user finds that existing platform resource scarce capacity is with the load of supporting business visit or when needing to reduce the platform resource of renting, its login resource allocation scheduling unit is order-resource again, dynamically adjusts resource requirement quantity.

(33) the resource allocation scheduling unit sends resource to execution space management module and applies for request again; Carry out the space management module to the adjusted resource of platform resource manager application, and change original professional configuration of carrying out the space, adjust virtual machine instance number and the professional engine instance number of carrying out; So far, the cloud platform according to platform user request finish the dynamic adjustment of resource.

Step 4, the cloud platform is supported the operation of UNE business: professional business at the cloud platform is carried out when being performed in the engine, and at the business of heterogeneous networks, protocol stack adapter that the cloud platform is adopted and corresponding protocol can be different; And according to the characteristics of different network service, the cloud platform is also different to the support function of service condition; But they are identical basically.For example, this step is being handled service request that network reports or during by the professional service request of self initiating, is all being comprised following content of operation::

(41) service request arrives load equalizer, and according to professional trigger policy, service request is forwarded to concrete business by load equalizer and carries out engine instance.

(42) the professional respective protocol stack adapter of carrying out engine instance receives and transmits the service request of coming, after this service request carried out dissection process, be packaged into platform inside story incident, according to the subscribing relationship of business, this inside story incident is sent to corresponding business instance management unit to resource.

(43) the srvice instance administrative unit is according to the session identification in the message event, search srvice instance corresponding with it, if find, then this message event is sent to this srvice instance and carries out Business Processing, otherwise will create new srvice instance and the session identification in message event is saved in the srvice instance map listing of srvice instance administrative unit self.

(44) message event is sent in the event queue of corresponding service example, this srvice instance is packaged into Task and puts into the professional task of carrying out engine and carry out formation and handle, for stateless business, after Business Processing finished, srvice instance deleted this srvice instance and corresponding session identification thereof with informing business instance management unit from the srvice instance mapping; For the business that state is arranged, srvice instance will still be kept in the srvice instance mapping, wait for the follow-up business request.

(45) there is the follow-up business request of state service will directly send in the respective protocol stack adapter of corresponding service execution engine, through step (42), the resolved one-tenth inside story of follow-up business request incident, send to corresponding service instance management unit, by the session identification in this incident, the srvice instance administrative unit finds the corresponding business example to carry out corresponding service and handles; The srvice instance that state is arranged is after handling whole service logic, and informing business instance management unit deletes srvice instance itself and session identification mapping thereof.

(46) this professional system handles result is transferred into corresponding protocol stack adapter, sends to network.

At last, specify an embodiment: the realization flow of the three party service of cloud platform operation UNE.This business can be finished: the user carries out click to dial from the webpage that the Internet-browser registering service provides, and realizes the video calling of mobile phone terminal A and cable digital TV terminal B.The whole service process relates to internet terminal, telecommunications network terminal and Broadcasting Cable Network terminal, has embodied the support of cloud platform of the present invention to three kinds of Internet resources.The whole service flow process is as shown in Figure 9:

In the whole service, relate to of the support of cloud platform, be respectively http protocol, Soap agreement and Session Initiation Protocol three kinds of agreements.How the business execution engine that hereinafter is described in detail respectively wherein supports three kinds of agreements.

Steps A, when user's internet usage browser carries out the login of business dialing webpage, what use is professional support to http protocol, owing to use different language exploitation webpage to need corresponding engine to support, the webpage of this embodiment is to use the JSP language development.Figure 10 has described the HTTP processing of request method that service enabler sends from browser the user.

Referring to Figure 10,, carry out engine centering at the cloud platform service because the Http request is stateless, srvice instance arrives with service request at every turn and is created, along with service request disposes and deleted, can not be stored in the srvice instance administrative unit, idiographic flow is described as follows:

(1) user is from browser registering service network address, Http Get request for this webpage be sent in the cloud platform should the corresponding load equalizer of business in;

(2) load equalizer select target business is carried out engine, and the Http Get request of receiving is sent to destination address;

(3) after the Http protocol stack of target service execution engine listens to the Http Get request of new arrival, it is packaged into the HttpEvent incident,, the HttpEvent incident is sent to corresponding business instance management unit according to the service resources ordering information;

(4) the srvice instance administrative unit is searched session id in the HttpEvent incident therewith to the srvice instance of coupling from the mapping of srvice instance and session id;

(5) owing to can not find the corresponding business example, then the requested service container is created new srvice instance;

(6) the JSP engine is created new srvice instance, and it is maintained in the srvice instance and session id map listing of srvice instance administrative unit;

(7) the HttpEvent incident adds in the processing queue of new business example, be packaged into Task enter the cloud platform carry out wait in the formation of engine processed;

(8) newly-generated Task is performed the relevant information that thread process Jsp engine internal is extracted HttpEvent, generates HttpRequest, carries out the respective handling operation;

(9) Task is processed finish after, generate HttpResponse and give Http protocol stack;

(10) srvice instance informing business instance management unit is deleted the mapping at own place from srvice instance and session id map listing;

(11) the Http protocol stack is packaged into the Http response message with the HttpResponse that receives, is sent to user browser again, thereby makes web page contents be presented in face of the user.

Step B, through top handling process, the user opens the dialing webpage, and input video both call sides call address sends call request.This process is actually the user and has sent a WebService call request to business from browser.The support that how web service is provided referring to this cloud platform that Figure 11 showed.

Platform for service developer exploitation Bpel business, finally provides WebService service to network by the Bpel business by open Bpel business development interface again.In fact each Bpel business comprises Bpel script logic and two parts of Bpel script engine, and Bpel script logic is comprised in the Bpel script engine and is performed, as shown in professional container among Figure 10; The Bpel script engine presents to platform as the outermost layer of business.In this business, the professional outwards open WebService calling interface of Bpel is to accept the webpage click call request, sets up the calling both sides video calling.

Each WebService message is actually by carrying Soap message on the Http message and realizes, so cloud platform of the present invention need use Http protocol stack and Soap protocol stack to the support of WebService message.Idiographic flow is described as follows:

(1) user is from click-to-dial webpage incoming call both sides address, and click-to-dial.Browser produces relevant Web Service request.This request is sent to the load equalizer of cloud platform by the carrying of Http agreement;

(2) load equalizer access service policy library obtains address and port that target is carried out engine;

(3) destination address and port are returned to load equalizer in the business game storehouse;

(4) load equalizer is forwarded to the Http protocol stack adapter that target is carried out engine with Web Service request.The Http protocol stack adapter of cloud platform has comprised a Http server and Web container, is deployed with Soap protocol stack adapter in the container.After Web Service request is received by the Http protocol stack, can extract the Soap message body that is carried in the Http bag and give Soap protocol stack adapter and do further parsing;

(5) Soap protocol stack adapter is resolved Soap message body, is packaged into the Soap incident of platform inside.Owing to mostly being stateless, calling of Internet service call, yet in order to support minority to have the Internet service of state and cloud platform telecommunication service processing method to be consistent, the Soap protocol stack gives a session Id at random can for the Soap incident, is used to identify the residing session of this Soap message.Have session Id as if in the Soap message, then the Id that gives at random with the replacement of the session Id in the Soap message.The Soap incident is sent in the call instance manager of corresponding service;

(6) the call instance manager in the example mapping table, search with the Soap incident in the call instance of session Id coupling;

(7) if do not have respective instance then call the method that professional container produces call instance;

(8) professional container produces the example of corresponding Bpel business, and srvice instance and session Id are kept in the professional corresponding call instance mapping table in couples;

(9) newly-generated call instance is packaged into the TASK that executes the task that the execution engine can be handled, and the TASK of generation is inserted into and carries out engine formation end;

(10) execution thread obtains TASK and execution from the head of the queue of engine formation;

(11) the third party call logic is called the Sip protocol stack in the TASK logic, sends session to the calling and called both sides and sets up request (annotate: the SIP idiographic flow of third party call logic sees also the ParlayX relevant criterion, does not do specifying here);

(12) after TASK finishes relevant treatment, send a WebService and respond the Soap protocol stack, the result who this time calls out has been write down in the inside;

(13) Soap protocol stack and the collaborative work of Http protocol stack produce the Http response results and send to user browser.

Step C, professional execution engine and calling both sides are carried out the Sip Signalling exchange, set up video call.In this process, though both sides are telecommunications network terminal and Broadcasting Cable Network terminal, but, because Broadcasting Cable Network terminal (for example digital TV set-top box) also is to insert core net and support Session Initiation Protocol by IP, so, how to support Session Initiation Protocol so this part content only illustrates cloud platform service execution engine with Broadcasting Cable Network terminal (as SIP phone) in essence different not.

Because setting up, session relates to the mutual of multiple sip message (comprising request and response) in the process again, and the professional engine of carrying out is as broad as long to its treatment mechanism, so only how handling INVITE with business execution engine here is that example describes, referring to Figure 12, introduce the professional flow process of carrying out engine treatment S IP message.

(1) software equipment of the sip terminal of user side or support Session Initiation Protocol sends INVITE to load equalizer;

(2) load equalizer inquiry business policy library;

(3) response is returned in the business game storehouse, and the purpose business that request is forwarded to is carried out engine instance address and port;

(4) load equalizer is forwarded to destination address with this request;

(5) the professional sip protocol stack of carrying out engine instance gets access to INVITE, be packaged into platform internal event-INVITE incident, navigate to this incident by service trigger criteria and belong to which business, and this incident is sent to the srvice instance manager that is registered to the SIP adapter;

(6) when the instance management device receives an incident, the session id in the normally extraction incident is inquired about this ID and already present call instance mapping table removes to obtain call instance.For this scene, INVITE is the conversation initial request, and the instance management device directly calls professional container, and request produces new call instance;

(7) the instance management device calls the new case method of establishment of professional container;

(8) professional container produces the new call instance of corresponding service, returns to the instance management device, and new example is added in session id and the example mapping table;

(9) the INVITE incident is passed to new call instance, and this call instance is packaged into carries out the TASK that executes the task that engine can be handled, and the TASK of generation is inserted into and carries out engine formation end;

(10) carry out engine and have an execution thread of running always, it obtains TASK and execution from engine formation head of the queue.

The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being made, is equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
