2, application scenarios
The user carries notebook computer or smart machine that mobile print service client software is installed and roams in environment, when the demand of printing, promptly utilizes default printer to print, and print out task will be assigned on the printer of the most close user's current location.The user is according to screen prompt, and the place obtains print result to corresponding printer, finishes printing.
3, technical description
1) printer dispatch service
As Fig. 1, the main task of printer dispatch service is the current location according to the user, prints for the user seeks nearest printer.Certainly the strategy of scheduling also can design according to other principle, such as add the judgement of whether just doing for printer, if nearest printer is being carried out print out task, and the inferior near printer free time, then print out task is dispatched to inferior near printer, to avoid wait.The printer dispatch service provides service by issue printer scheduling broker, adopts agency's advantage to be, scheduling strategy can be encapsulated in and move to the user side operation among the agency, avoids unnecessary network service, reduces offered load.The renewal that the while client can be obtained dispatching algorithm easily by the mode of update agent.
2) search service
Search the service in the service management system, its function comprise service issue, obtain the maintenance with information on services, a good service of searching should be able to be supported the adding of new service fast, support the client to obtain service fast, and the discovery service of having lost efficacy and it is removed from service list automatically.It mainly comprises the requirement of three aspects:
The issue of new service: a new service, comprise that dispatch service, printer build-in services or print service will add in the existing systems, no matter how dispatching algorithm realizes or the model of new printer, what the network address is, all should be able to be accepted by system rapidly and come into operation, and do not need other parts of system are made adjustment.
Obtaining of service: client can be obtained corresponding service easily and fast, and realizes calling service function automatically.
The validity of the service that provides is provided: because network or equipment failure, some service may be temporary transient or permanent unavailable, and the while, the inefficacy of the service of searching oneself can't be initiatively informed in corresponding apparatus and service probably owing to fault is sudden.If can not be in time the service of these inefficacies be removed from service list, then system may offer the user with an invalid service, thereby causes trouble for user's normal use.
The present invention issues, obtains and leasing mechanism by service, satisfies above-mentioned requirements.
● the service issue
Whenever a new service request adds fashionablely, its first-selection is searched service by the broadcast mode search, after finding the service of searching, obtains from server and to search the service broker, calls corresponding method issue oneself.At first, it need search the register method among the service broker, provides required attribute information to system, printer name, printer place, printer model etc.Secondly, it need provide an one's own service broker to management service.The service broker has encapsulated the method that the user calls service function, provides service by unified interface to the user.Fig. 2 has shown the process of service issue.
● service is obtained
When the client need use the function of certain service, at first provide the attribute of required service to the service of searching.The service of searching is searched in service list according to Service Properties, and satisfactory service broker is sent to the client.The client searches the method for serving in the service broker's object that returns by calling, and obtains the function of respective service.Fig. 3 has shown that the client obtains the process of service.
● leasing mechanism
In order in time to detect the inefficacy of service, we have used leasing mechanism.After service issue, to come into force in order to make service, the ISP need file an application by the method for searching the service broker and providing is provided.If application goes through, then the service of searching will be returned one " lease ".A lease has been represented a period of time, and it is effective that this service is considered in the term of validity of lease.Work as lease expires, if continue to provide service, then must be to searching the new lease of service request, as the not application that exceeds the time limit, then this service will be deleted from the service list of the service of searching.
In this way, hinder for some reason and behind the catastrophic failure, even any related announcement is not received in the service of searching, this service also can be eliminated from service list automatically because of lease expires when a certain equipment that service is provided.
3) notebook computer client
The notebook computer client is passed through to bring in constant renewal in self-position, and calls the function of printer dispatch service and printer build-in services, guarantees that the default printer of system is the nearest printer of current distance, thereby realizes the function that the user prints nearby.Client is by refreshing the printer configuration that self-position comes update system, and its concrete steps are described below as shown in Figure 4:
1.1 client is obtained current location;
1.2 compare with original position,, then finish refresh process if the position does not change; If the position changes, then start the printer configuration process;
The printer configuration process prescription is as follows:
1.1 inquire about nearest printer attribute to the printer dispatch service by the client current location;
1.2 if this printer is current system default printer, then finish layoutprocedure; Otherwise execution in step 3
If 1.3 this printer has been equipped with driver in system, then execution in step 6; Otherwise execution in step 4;
1.4 search service by the printer attribute query, obtain printer build-in services agency; As obtain failure, and then report the printer build-in services and do not exist to the printer scheduler program, finish layoutprocedure; Otherwise execution in step 5;
1.5 call the installation method of installation agent;
1.6 be the system default printer with printer setup and finish layoutprocedure;
4) smart machine client
The smart machine client be because of can't installing printed driver, therefore need realize printing function by the Method of printing that calls the print service agency and provided.Different with the notebook computer client, the smart machine client does not need constantly to refresh self-position, but the service broker who just obtains nearest print service when receiving user's print request realizes the function that the user prints nearby.Its concrete steps are described below as shown in Figure 5:
1.1 the user calls the client printing function;
1.2 client is obtained current self-position information by location-based service; If current location is identical with original position, then execution in step 6; Otherwise execution in step 3;
1.3 obtain nearest printer attribute by the printer dispatch service;
1.4 act on behalf of to searching the services request print service according to printer name; As ask success, execution in step 6; Otherwise execution in step 5;
1.5 do not exist to the printer service of the calling service of reporting,, then return step 3 if still have operable print service in the system; Otherwise return error message and finish print procedure;
