Abstract
A client terminal CT transmits an acquisition request for musical composition information. An associated information provision server KS continuously receives the acquisition request at a given time interval. The associated information provision server KS transmits timing specification information along with the musical composition information corresponding to the acquisition request to the client terminal CT. The timing specification information specifies timing for the client terminal CT to transmit the acquisition request next. The associated information provision server KS controls a polling interval for acquisition requests. In this manner, acquisition requests can be distributed to those transmitted at a given time interval and those received in accordance with the timing specification information. A simple method can be used to prevent acquisition requests from being concentrated on the associated information provision server KS.

Consult Fig. 8 and flow chart shown in Figure 9, how will to explain below through specifying the sequential that receives the request of obtaining of musical works information from client terminal CT to make relevant information that server KS control polling interval is provided.
(1-8-1) has the polling interval control flow of specifying time delay
In step SP1 shown in Figure 8, the RS of the radio station musical works A that in current program, goes on the air advances to next step SP2 then.
In step SP2, behind the musical works A that goes on the air, the RS of radio station provides server KS beginning playing back music works A notice relevant information.
In step SP11, relevant information provides server KS to use musical works information database 93 (Fig. 4) to safeguard the musical works information database relevant with the type of a plurality of musical works.More particularly, musical works information comprises title and the numbering etc. of the CD of the title that relates to the polytype musical works and singer's title, record respective piece of music.Be necessary and be provided on the client terminal CT with the relevant musical works information of musical works A from the RS of radio station notice.For this reason, relevant information provides server KS with previous musical works information updating to the musical works information relevant with musical works A, and advances to next step SP12. subsequently
At step SP21, client terminal CT receives the musical works A that play at step SP1 by the RS of radio station so that the user can listen to it.At step SP22, client terminal CT provides server KS to carry out poll through sending to relevant information with 30 seconds interval for the request of obtaining of musical works information.Musical works information comprises the title relevant with musical works A and singer's name.Client terminal CT advances to next step SP23 then.
Relevant information provides server KS management about the visit quantity to the request of obtaining of the musical works information sent from a plurality of client terminal CT.At step SP12, relevant information provides server KS to judge whether visit quantity surpasses defined threshold.
If the result negates then not provide the control section 90 of server KS to apply too much load to relevant information.This representes that also network does not receive the multiple services influence of mistake that the concentrated request of obtaining to musical works information causes.In this case, relevant information provides server KS to advance to next step SP13.
At step SP13, judgement did not have multi-load to put on control section 90 or network did not receive multiple services the influence.In response to the request of obtaining from client terminal CT, relevant information provides server KS will offer client terminal CT about the musical works information of musical works A through network 2.This information is prepared to provide subsequently.
On the contrary, if the result of step SP12 then provides the control section 90 of server KS to apply too much load to relevant information for certainly.This representes that also network receives the multiple services influence of mistake that the concentrated request of obtaining to musical works information causes.In this case, relevant information provides server KS to advance to next step SP14.
At step SP14, relevant information provides server KS will offer client terminal CT about the musical works information of musical works A through network 2.This information is prepared to provide subsequently.In addition, relevant information provides server KS to specify n second, n after second client terminal CT should send the next request of obtaining to musical works information, wherein n is not meant tailor-made 30 of the normal request sequential that is.
At step SP23, client terminal CT provides server KS to obtain musical works information from relevant information.In addition, client terminal CT asks after second to obtain musical works information at request sequential n.This sequential is longer than normal 30 second wheels and is ask at interval.
When relevant information provided server KS after this to specify next one request sequential, musical works information was asked to obtain at the n of request sequential in client CT terminal after second.When not specifying next one request sequential, client terminal CT presses 30 seconds normal interval request to obtain musical works information.
As shown in Figure 9, relevant information provides server KS to identify: owing to the concentrated request of obtaining from a plurality of client terminal CT had multi-load to put on control section 90.In this case, relevant information provides server KS to specify a given time delay (n is after second), and client terminal CT should send the request of obtaining to musical works information after during this period of time.This causes with the polling interval of other client terminal and staggers, thereby prevents on network, to form multi-service.
When increasing the load on the control section 90 when concentrating from the request of obtaining of client terminal CT, the time delay (n second) that relevant information provides server KS to prolong the request sequential gradually, this time delay client terminal CT and should send the request of obtaining musical works information.Like this, relevant information provides server KS can prevent that the load on the control section 90 from surpassing the threshold value of regulation.
After too much applying load on the control section 90, relevant information provides server KS to specify different time delays (n second) to each client terminal CT.Perhaps, relevant information provides server KS to can be all client terminal CT and specifies identical time delay (n second), and this time delay is used for all client terminal CT and after control section 90 overloads, sends the request of obtaining.
(1-8-2) has the polling interval control flow of fixed time
At step SP41 shown in figure 10, the RS of the radio station musical works A that in current program, goes on the air advances to next step SP42 then.
In step SP42, behind the musical works A that goes on the air, the RS of radio station provides server KS beginning playing back music works A notice relevant information.
In step SP51, relevant information provides server KS to use musical works information database 93 (Fig. 4) to safeguard the musical works information database relevant with the type of a plurality of musical works.Be necessary and be provided on the client terminal CT with the relevant musical works information of musical works A from the RS of radio station notice.For this reason, relevant information provides server KS that previous musical works information updating is the musical works information relevant with musical works A, and advances to next step SP52. subsequently
At step SP61, client terminal CT receives the musical works A that play at step SP1 by the RS of radio station so that the user can listen to it.At step SP62, client terminal CT provides server KS to carry out poll through sending to relevant information with 30 seconds interval for the request of obtaining of musical works information.Musical works information comprises the title relevant with musical works A and singer's name.Client terminal CT advances to next step SP63 then.
Relevant information provides server KS management about the visit quantity to the request of obtaining of the musical works information sent from a plurality of client terminal CT.At step SP52, relevant information provides server KS to judge whether visit quantity surpasses defined threshold.
If the result negates then not provide the control section 90 of server KS to apply too much load to relevant information.This representes that also network does not receive the multiple services influence of mistake that the concentrated request of obtaining to musical works information causes.In this case, relevant information provides server KS to advance to next step SP53.
At step SP53, judge that multi-load does not put on control section 90 or network did not receive multiple services the influence crossing.In response to the request of obtaining from client terminal CT, relevant information provides server KS will offer client terminal CT about the musical works information of musical works A through network 2.This information is prepared to provide subsequently.
On the contrary, if the result of step SP52 then provides the control section 90 of server KS to apply extra load to relevant information for certainly.This representes that also network receives the multiple services influence of mistake that the concentrated request of obtaining to musical works information causes.In this case, relevant information provides server KS to advance to next step SP54.
At step SP54, relevant information provides server KS will offer client terminal CT about the musical works information of musical works A through network 2.Prepare this information then to provide.In addition, relevant information provides the server KS fixed time " hh:mm:ss ", and client terminal CT should send the next request of obtaining to musical works information on this time, in this example, hh corresponding to hour, mm corresponding to minute and ss corresponding to second.Fixed time is longer than the normal poll time.
At step SP23, client terminal CT provides server KS to obtain musical works information from relevant information.In addition, client terminal CT should the time in the preceding clock maintenance according to himself of the request sequential arrival " hh:mm:ss " that server KS appointment is provided by relevant information.At the appointed time " hh:mm:ss ", client terminal CT acquisition request musical works information.
After this, relevant information provides server KS to specify to be used to ask next time of sequential.At the appointed time locate client terminal CT acquisition request musical works information.When asking sequential during the fixed time to next, client terminal CT was with normal 30 seconds interval acquisition request musical works information.
Shown in figure 11, relevant information provides server KS to identify: owing to obtain request from a plurality of client terminal CT concentrated, control section 90 had been applied crossed multi-load.In this case, relevant information provides server KS to specify the time for the request sequential, and client terminal CT should send the request of obtaining to musical works information on this time.Staggering through the polling interval that makes itself and other client terminal CT disperses the polling interval, thereby prevents on network, to form multi-service.
When concentrating from the request of obtaining of a plurality of client terminal CT and then increasing the load of control section 90, relevant information provides server KS to postpone the time of request sequential, and client terminal CT should send the request of obtaining that is used for musical works information in this time.Like this, relevant information provides server KS can prevent that the load on the control section 90 from surpassing the threshold value of regulation.
After control section 90 overloads, relevant information provides server KS to can be each client terminal CT appointment different time as the request sequential.Perhaps, relevant information provides server KS to can be all client terminal CT that after control section 90 overload, send the request of obtaining to specify the identical time as asking sequential.
(1-9) according to operation and the effect of first embodiment
According to above-mentioned configuration, can blockage information not provide the relevant information of system 1 that server KS is provided from the request of obtaining of a plurality of client terminal CT.Load on the control section 90 will be lower than the threshold value of regulation.In this case, relevant information provides the obtain request of server KS response from the musical works information of client terminal CT, and musical works information is offered client terminal CT.
After this, possibly block relevant information from the request of obtaining of a plurality of client terminal CT server KS is provided.Load on the control section 90 possibly surpass the threshold value of regulation.In this case, relevant information provides server KS to specify time delay or time immediately, so that formation time is poor between normal polling interval and the request sequential, and client terminal CT acquisition request musical works information on this time difference.
A plurality of client terminal CT requests are to provide server KS to obtain musical works information from relevant information.Provide relevant information specified time-delay of server KS or time to distribute to some client terminal CT, but do not distribute to other terminal.Because these client terminals CT is mixed, the request of obtaining of musical works information can not make relevant information provide server KS to block at one time.
Relevant information provides server KS only to need client terminal CT is specified time delay or time.After this just no longer need be such as the management and dispatching table musical works information is provided to the complex process of a plurality of client terminal CT.Might prevent that the multi-service of crossing on the network from not having and need apply unnecessary load to control section 90.
