Embodiment
The embodiment of the invention provides conversation processing method, system and device, and the session processing entities determines that the maximum of current sessions operation allows the processing time, and operation is handled to current sessions in this maximum allows the processing time.
In order to make those skilled in the art person understand the technical scheme that the embodiment of the invention provides better, the technical scheme that the embodiment of the invention provides is described in further detail below in conjunction with the drawings and specific embodiments.
The first embodiment flow chart of conversation processing method of the present invention is as shown in Figure 3:
Step 301: the session processing entities determines that the maximum of current sessions operation allows the processing time.
In embodiments of the present invention, the entity that all that relate in the session processing procedure are handled this session is referred to as the session processing entities, and the session processing entities is the logical abstraction entity, is not that its concrete form and deployment are limited.For example: set up in the process a session, UE, AF, x-RACF etc. can abstractly become the session processing entities.
Wherein, session operation comprises at least a in session foundation, session modification, session release or the session inquiry.
Wherein, session processing entities determines that the maximum of current sessions operation allows the processing time to comprise: the session processing entities determines that according to the configuration data of self maximum of current sessions operation allows the processing time; Or the session processing entities determines that according to the input data of the terminal of described current sessions correspondence the maximum of current sessions operation allows the processing time; Or the information that the session processing entities sends according to external entity determines that the maximum of current sessions operation allows the processing time; Or the session processing entities determines that according to session time started to the session termination time maximum of current sessions operation allows the processing time.
Allow several modes in processing time to be described in detail respectively to the above-mentioned maximum of enumerating settled really preceding session operation below.
When the session processing entities determines that according to the configuration data of self maximum of current sessions operation allows the processing time, the configuration data that this configuration data can produce for the classification according to the operation of corresponding current sessions, common classification can be for by professional classification, jump the classification of session processing entities, press the user class classification, classify, press session action type classification etc. by session priority by last one of session processing entities.To be categorized as example by business, suppose that this business is VOD business (Video On Demand, i.e. video request program), the maximum permission processing time that the operation of VOD traffic class conversational can be set is 20 seconds; Be categorized as example to jump the session processing entities by last one, it is 30 seconds that all maximum permission processing times of jumping the session operation of session processing entities from last one of main frame " abc " by name can be set.
When the session processing entities determines that according to the input data of the terminal of current sessions correspondence the maximum of current sessions operation allows the processing time, be operating as session with current sessions and be established as example, the user can be when setting up this session, the maximum permission processing time of this session is set up in input in user terminal, and the current sessions processing entities can obtain this maximum and allow the processing time.
When the information that the session processing entities sends according to external entity determines that the maximum permission of current sessions operation is during the processing time, when this external entity is last one of a current sessions processing entities when jumping the session processing entities, jumps the information that the session processing entities sends according to last one and determine that the maximum of current sessions operation allows the processing time to comprise: last one jumps the session processing entities sends all to the current sessions processing entities and comes from this on sessions of jumping the session processing entities and allow current sessions processing entities to maximum permission processing time of each session operation employing wherein; Or last one jump the session processing entities and send all to the current sessions processing entities and come from the maximum permission processing time that some session of jumping the session processing entities this on allow current sessions processing entities that each session operation is wherein adopted; Or a last jumping session processing entities sends the maximum permission processing time that operation is adopted to current sessions to the current sessions processing entities.When this external entity is the storage of subscriber data entity of current sessions processing entities, can determine that the maximum of current sessions operation allows the processing time according to the information that the storage of subscriber data entity sends, the storage of subscriber data entity can be CLF (Connectivity Session Location and Repository Function, connective session location and memory function entity), HLR (Home Location Register, attaching position register), HSS (Home Subscriber Server, home signature user server), SPR (Subscription Profile Repository, the subscription data warehouse) etc., with external entity is that a last jumping session processing entities is consistent, when the storage of subscriber data entity sent user data to the session processing entities, the maximum that can simultaneously all sessions of this user be operated allowed the processing time, or the maximum of a certain class session operation allows the processing time, or the maximum of some session operations allows the processing time to send to the current sessions processing entities.
When the session processing entities determines that according to session time started to the session termination time maximum of current sessions operation allows the processing time, session wherein stops and can trigger in the following manner: when session is finished dealing with, determine the maximum processing time end that allows; The Session Resources of current sessions operation discharges the Session Resources of current sessions operation during by the session preemption of other higher priority, determines maximumly to allow the processing time to finish; When receiving that last one jumps the message that the indication of session processing entities finishes the current sessions operation, as the session release message, handle when cancelling message etc., determine maximumly to allow the processing time to finish; When the message of receiving that next end session of jumping the transmission of session processing entities is operated,, determine maximum permission processing time end as the session unexpected message, when failed message is handled in session; When receiving user's deferred information that the user storage entity sends, determine the maximum processing time end that allows.
Step 302: operation is handled to current sessions in maximum allows the processing time.
Wherein, operation is handled and comprised to current sessions in maximum allows the processing time: the maximum with described session processing entities allows the processing time as input, next that calculates is jumped session processing entities allow the processing time to be sent to next to the maximum of described current sessions operation to jump session processing entities; Or according to expectation processing time of current sessions operation to current sessions operation handle; Or in maximum allows the processing time to current sessions operation dispatch.
The second embodiment flow process of conversation processing method of the present invention as shown in Figure 4, this embodiment shows and jumps the session processing entities to next and send the process that its maximum to the current sessions operation allows the processing time:
Step 401: the session processing entities determines that the maximum of current sessions operation allows the processing time.
The concrete maximum of determining the current sessions operation allows the mode described among processing time and conversation processing method first embodiment of the present invention consistent, does not repeat them here.
Step 402: calculate next and jump the maximum permission processing time of session processing entities to this session operation.
The current sessions processing entities can be calculated the maximum permission processing time of next jumping session processing entities to the current sessions operation according to self maximum permission processing time, actual treatment time and message communicating to described current sessions operation time of delay.
Wherein, the current sessions processing entities allows the processing time to the maximum of this session operation, is designated as t0, should be not less than following three sections time sums: to the processing time of this session operation, be designated as t1 before next jumps session processing entities transmission session processing request message; Receive that next session of jumping the session processing entities handles behind success message the processing time of this session operation, be designated as t2; To next jump session processing entities send session to handle request message after to receiving that next jumping session processing entities to the processing time between this session operational processes success message, is designated as t3, i.e. t0 〉=t1+t2+t3.Above-mentioned t3 further comprises: jump the session processing entities to next and send the communication delay that request message is handled in session, be designated as t4; Next jumps the communication delay that the session processing entities sends session operational processes success message, is designated as t5; Next jumps the actual treatment time of session processing entities to this session operation, is designated as t, i.e. t3=t4+t5+t.Therefore as can be known, t≤t0-t1-t2-t4-t5 according to above-mentioned two formulas.
Wherein, t2 can be by acquisition that the time used of a plurality of sessions operation of nearest processing is averaged; Can obtain by the mode of test for communication delay, for example, the communication protocol that one group of keep-alive message is arranged for definition, current processing entities is jumped processing entities to next and is sent a message, next is jumped and sends a response message to deserving the pre-treatment entity in a short period of time after processing entities is received this message, for current processing entities, from sending a message to the time of receiving response message, be designated as t6, t6 can regard above-mentioned t4 and t5 sum as, therefore next jumps the maximum that the session processing entities is got aforementioned t to the maximum permission processing time of session operation, be t=t0-t1-t2-t6, relative with t5 less as t4, in the time of can ignoring t6, further simplify t=t0-t1-t2; Certainly, can suppose that also t1 and t2 hour, further simplify t=t0.Above-mentioned simplification account form can be selected according to the actual conditions of various times.
Step 403: the maximum that will calculate allows the processing time to be sent to next and jumps the session processing entities.
In conjunction with the concrete application flow of the invention described above conversation processing method second embodiment as shown in Figure 5, comprise UE, AF, SPDF and four entities of x-RACF in this flow process:
Step 501:UE sends service request to AF, and the maximum permission processing time that comprises indication session foundation in this service request is 100 seconds.
After step 502:AF receives the service request of UE, send authorization requests to SPDF, because AF itself takies the regular hour to the processing of service request with communicating by letter, and is assumed to be 10 seconds, it is 90 seconds that the maximum of the session foundation that then comprises in the authorization requests that SPDF sends allows the processing time.
After step 503:SPDF receives the authorization requests of AF, send resource request to x-RACF, because SPDF itself has taken the regular hour to the processing of authorization requests with communicating by letter, be assumed to be 15 seconds, it is 75 seconds that the maximum of the session operation that then comprises in the resource request that x-RACF sends allows the processing time.
Step 504:x-RACF carried out resource allocation for this session operation after receiving resource request, and this x-RACF should allow to finish session in the processing time and set up 75 seconds maximum.
Step 505: set up when x-RACF finished session in 75 seconds, then return the resource request success response to SPDF; Do not set up when x-RACF finished session in 75 seconds, then return the resource request failure response to SPDF.
According to the inventive method embodiment, in 75 seconds maximums allow the processing time, x-RACF can also carry out flexible dispatching to the session operation, for example, in preceding 30 seconds, x-RACF can't distribute enough resources for this session, then x-RACF does not refuse the foundation of this session, but may be this session Resources allocation in remaining 45 seconds, promptly, just can set up session as long as successfully carried out resource allocation in any time in 75 seconds.
The 3rd embodiment flow process of conversation processing method of the present invention as shown in Figure 6, the process that this embodiment shows expectation processing time according to current sessions operation operation is handled to current sessions:
Step 601: the current sessions processing entities determines that the maximum of current sessions operation allows the processing time.
The concrete maximum of determining the current sessions operation allows the mode described among processing time and conversation processing method first embodiment of the present invention consistent, does not repeat them here.
Step 602: determine the expectation processing time to this session operation.
The expectation processing time of session operation comprises stand-by period and the necessary processing time that this session is operated.Stand-by period is further divided into time and next jumping session processing entities of wait of waiting for the available sessions resource and returns the response time that processing finishes.
Wherein, for operating with a kind of session, the necessary processing time each time is all more approaching, therefore can estimate the necessary processing time of current sessions operation by the processing time of completed other session operation of the same race.For example, write down the actual treatment times of nearest 100 session operations of the same race, with the mean value that calculates the necessary processing time of expectation as the current sessions operation.
Wherein, the time of waiting for the available sessions resource is because the current sessions operation can't obtain enough resources, therefore needs to wait for the stand-by period that could obtain enough resources after other session operation discharges the session resource.The current sessions processing entities need determine the required Session Resources of current sessions operation by which session operation is taken thus, and these sessions operate in the remaining time of determined expectation survival time when setting up, and according to what of remaining time, determine which session operation can to satisfy the enough Session Resources of current sessions operation acquisition corresponding remaining time, be the time of waiting for the available sessions resource this remaining time in.For example, suppose that current sessions need take the 25M downlink bandwidth on the transmission path A, and total total 50M downlink bandwidth on the path A, currently taken the 10M bandwidth by session 1, taken the 10M bandwidth by session 2, taken the 20M bandwidth, and the survival time that session 1 is estimated also is left 20 seconds by session 3, the also remaining 25 seconds survival time that session 2 is estimated, the also remaining 30 seconds survival time that session 3 is estimated.Therefore, owing to only remain the idle downlink bandwidth of 10M on the path A, therefore can not satisfy the Session Resources demand of current sessions operation, after the current also remaining expectation survival time, the shortest session 1 discharged Session Resources, path A will have the idle downlink bandwidth of 20M, but still can not satisfy the Session Resources demand of current sessions operation; After current short session 2 of also remaining expectation survival time second discharges Session Resources, path A will have the idle downlink bandwidth of 30M, can satisfy the demand of current sessions operation 25M Session Resources.Therefore, the time of the wait available sessions resource of current sessions operation is exactly the 2 current also remaining expectation survival times of session, promptly 25 seconds.
Wherein, wait for that next jumps session processing entities and return response time that processing finishes and can jump session that the session processing entities sends to the current sessions processing entities by next and estimate that the processing time calculates; The current sessions processing entities have a plurality of next when jumping session processing entities, expectation processing time of finishing the latest can be waited for that as calculated value next jumps the response time that processing that session processing entities returns finishes.For example, the current sessions processing entities has three next jumping session processing entities, is respectively entity 1, entity 2 and entity 3.The current sessions processing entities receives that at 00:00:00 the expectation processing time of the session operation of entity 1 is 30 seconds, and promptly entity 1 is estimated to finish the session operational processes at 00:00:30; The current sessions processing entities receives that at 00:00:10 the expectation processing time of entity 2 is 25 seconds, and promptly entity 2 is estimated to finish the session operational processes at 00:00:35; The current sessions processing entities receives that at 00:00:15 the expectation processing time of entity 3 is 5 seconds, and promptly entity 3 is estimated to finish the session operational processes at 00:00:20.Therefore, the response time that all next jumping session processing entities are returned the processing end should be 00:00:35, with respect to the response time of returning the latest, i.e. 00:00:20, wait for all next jump session processing entities and return the response time that processing finishes and be expected to be 15 seconds.
Step 603: judge to estimate whether processing time and the maximum difference in processing time that allows surpass threshold value, if then execution in step 604; Otherwise, execution in step 605.
Threshold value is for handling the time value that needs set in advance according to session, this value can be integer, for example, threshold value is set to 10 seconds, the maximum permission processing time is 50 seconds, and when estimating that the processing time is 50 seconds, the difference of then above-mentioned two times is 0 second, less than threshold value, permission is operated current sessions and is handled; When estimating that the processing time is 30 seconds, the difference of then above-mentioned two times, allowed the session operation is handled also less than threshold value for negative 20 seconds; When estimating that the processing time is 70 seconds, the difference of then above-mentioned two times is 20 seconds, greater than threshold value, then current sessions is not operated and is handled.
Step 604: finish processing, finish current flow process to the session operation.
The current expectation processing time has surpassed the threshold value that sets in advance with the maximum difference in processing time that allows, and then can not handle the current sessions operation.
Step 605: in maximum allows the processing time, the session operation is handled, finished current flow process.
Further, in the foregoing description three, the current sessions processing entities also can will estimate that the processing time feed back to the user by modes such as literal, voice or videos, and whether the user decides in its sole discretion to continue current sessions operated according to this expectations processing time and handle.Perhaps, the current sessions processing entities will estimate that the processing time sends on it one and jump the session processing entities, and whether last one jumps the session processing entities determines to continue this session operated according to this expectations processing time and handle.By the foregoing description three, no matter session processing entities still is that the user can both know the session expectation processing time, and select whether to cancel processing according to this to the current sessions operation in expectation processing time, avoided the session operation to waste user's the time and the processing resource of session processing entities, effectively improved user's network and experienced owing to finishing for a long time to handle.
In conjunction with the concrete application flow of the invention described above conversation processing method the 3rd embodiment as shown in Figure 7, comprise UE, AF, SPDF, x-RACF1 and five entities of x-RACF2 in this flow process:
Step 701:UE sends service request to AF.
Step 702:AF sends authorization requests to SPDF.
Step 703:SPDF sends resource request to x-RACF1.
Step 704:SPDF sends resource request to x-RACF2.
Step 705:x-RACF1 sends temporary resource request response to SPDF, and comprising the x-RACF1 expectation in this request response, to set up the time-delay of session be 60 seconds.
Step 706:x-RACF2 sends temporary resource request response to SPDF, and comprising the x-RACF2 expectation in this request response, to set up the time-delay of session be 80 seconds.
The expectation session that step 707:SPDF returns according to x-RACF1 and x-RACF2 set up time-delay and SPDF itself to processing time of session operation and communication delay etc., obtaining that session foundation that SPDF estimates delays time is 95 seconds, and to AF return authorization Temporary Response.
After step 708:AF receives and authorizes Temporary Response, time of operating according to the foundation time-delay and the AF processing session itself of the expectation session operation in this response and communication delay etc., the foundation time-delay that obtains the session of AF expectation is 105 seconds, and returns professional Temporary Response to UE.
After step 709:UE receives professional Temporary Response, the session foundation time-delay that obtains the AF expectation is 105 seconds, the maximum permission processing time of supposing the active user is 60 seconds, and the time-delay of estimating with maximum allow the processing time differ from 55 seconds greater than the threshold value that sets in advance 30 seconds, then the user cancels the current sessions operation, cancels message to AF transmission business.
Step 710:AF receives after business is cancelled message and cancels message to SPDF transmission mandate.
Step 711:SPDF receives after message is cancelled in mandate and sends resource repealing message to x-RACF1.
Step 712:SPDF sends resource repealing message to x-RACF2.
The 4th embodiment flow process of conversation processing method of the present invention as shown in Figure 8, this embodiment shows the process that operation is dispatched to current sessions in maximum allows the processing time:
Step 801: the session processing entities determines that the maximum of current sessions operation allows the processing time.
The concrete maximum of determining the current sessions operation allows the mode described among processing time and conversation processing method first embodiment of the present invention consistent, does not repeat them here.
Step 802: judge the maximum residue processing time that allows the processing time of current sessions operation, if the session operation of less residue processing time correspondence, then execution in step 803; If remain the session operation of processing time correspondence more greatly, then execution in step 804.
The current sessions processing entities may be handled a plurality of session operations simultaneously, so this session processing entities can allow the residue processing time in processing time that flexible dispatching is carried out in each session operation according to the maximum of current each session operation.Except judging that the maximum residue in processing time that allows is the processing time, the session processing entities can also be dispatched the session operation in conjunction with other factors, and these factors can comprise the urgency level of session operation, the significance level of session operation, the business classification of session operation etc.
Step 803: execution in step 805 is handled in the session operation of scheduling least residue processing time correspondence.
The current sessions processing entities is according to each maximum residue processing time that allows the processing time of session operation, and priority scheduling is handled the session operation of less residue processing time correspondence.Here remaining the processing time is the processing time that the maximum permission processing time deducts the session operation, and the processing time further comprises the time of this session operation awaits scheduling.
For example, the session processing entities begins session 1 is handled at 10:00:00, and it is 20 seconds that the maximum of session 1 allows the processing time; The session processing entities begins session 2 is handled at 10:00:03, and it is 10 seconds that the maximum of session 2 allows the processing time.Suppose that the current time is 10:00:05, then the residue processing time in 1 maximum permission processing time of session is 15 seconds, the residue processing time in 2 maximum permission processing times of session is 8 seconds, and session 1 and the session 2 current states of waiting for that scheduling is handled that all are in, then session processing entities priority scheduling session 2 is handled.Suppose that it is 5 seconds that this session processing entities is handled the time of each session, if dispatch not according to the residue processing time this moment, but handled session 1 earlier according to session foundation order, the maximum of session 2 allowed the residue processing time in processing time to be kept to 3 seconds when then session 1 was finished dealing with, and the session processing entities can't have been finished the processing to session 2 in this time; And if elder generation handles session 2, the maximum of session 1 allowed the residue processing time in processing time to also have 10 seconds when then session 2 was finished dealing with, and was enough to finish the processing to session 1, and therefore, this scheduling mode has improved the success rate to the session operational processes.
Step 804: suspend or abandon the session operation of residue processing time maximum is handled.
The session operation of bigger residue processing time correspondence is suspended or abandoned handling to the current sessions processing entities according to each maximum residue processing time that allows the processing time of session operation.Especially in the session processing entities because the session operation of bigger residue processing time correspondence is then suspended or abandon handling to CPU overload, memory space inadequate or need suspend or abandon processing to a part of session operation during by emergent session operation preempting resources by dispatching priority.Here remaining the processing time is the processing time that the maximum permission processing time deducts the session operation, and the processing time further comprises the time of this session operation awaits scheduling.
Need to prove, owing to generally have retransmitting function between the carrier-class session processing entities, therefore for suspending the session operation of handling as required, even this session operation has been abandoned by the current sessions processing entities, jumping session processing entities can be retransmitted the session operation that is dropped to this session processing entities on it, makes the session processing entities allow to finish in the processing time processing that this session is operated in the maximum of this session operation.
Step 805: judge whether to surpass the scheduling stand-by period that sets in advance, if, then return step 802, otherwise, execution in step 805.
The session processing entities generally can start a timer, and be the scheduling stand-by period time-count cycle of this timer, behind this timer expiry this session operation is rescheduled.The situation that need reschedule comprises that CPU overload, the current sessions operation of session processing entities can't obtain the policing rule inspection that enough Session Resources or current sessions operation can't be by the session processing entities etc.
When the CPU overload of session processing entities, this session processing entities at timer then after the default scheduling stand-by period, is dispatched the session operation again.For example; the session processing entities is when receiving the processing request of a certain session operation; the CPU of this session processing entities has been in serious overload; the maximum permission processing time of supposing this session operation is 20 seconds; then session processing entities can be according to the scheduling stand-by period; again this session operation is dispatched and handled after supposing to postpone for 10 seconds,, provide effective overload protection the session processing entities to alleviate the processing pressure of current C PU.In like manner, though the session processing entities is only delayed the processing time of a session operation for the processing pressure effect that reduces session processing entities CPU and little, if but the session processing entities is according to the scheduling stand-by period, handle again after current a plurality of sessions operation all postponed a period of time, then consider obviously to reduce the CPU processing pressure of session processing entities from whole structure.Certainly, if rescheduling session operation back CPU still transships, the session processing entities can be selected all directly to handle the session operation no matter whether CPU transships, after also can preferentially selecting to repeat to wait for the time-count cycle of a timer, according to judged result current sessions operation is dispatched, surpassed the maximum permission processing time up to this session operational processes success or processing time.
When the session operation can't obtain enough Session Resources, the session processing entities at timer then after the default scheduling stand-by period, was dispatched the session operation again.The Session Resources here comprises memory space, Internet resources, link bandwidth, IP address and port etc., though these Session Resources are shared by a plurality of session processing entities, but after the session operation that takies Session Resources discharges resource, other session operation of sharing this Session Resources can be used these Session Resources, finishes the processing to the session operation.Certainly, for session operated allocated Internet resources the time, the session processing entities can be disposable in scheduling process is the enough Internet resources of this session operated allocated, can be these session operated allocated part Internet resources when each scheduling also, finally be the enough Session Resources of this session operated allocated by the accumulation of repeatedly dispatching.
When the current sessions operation can't be checked by the policing rule of session processing entities, this session processing entities at timer then after the default scheduling stand-by period, was dispatched the session operation again.The policing rule here comprises: bandwidth limit, the on-line session that the user contracts counted limit, professional on-line session is counted limit etc.Need to prove that although the current sessions operation may be by the policing rule inspection of session processing entities, after the scheduling stand-by period, other session EO is handled, this session operation just can be by the policing rule inspection.For example, the on-line session operand limit of session processing entities is 1000, suppose to have existed at present 1000 on-line session operations, then new session operation just can't be by the inspection of this policing rule, because if set up the words of this session operation again, the on-line session number has just reached 1001, the restriction that has exceeded policing rule, but after a period of time (this time is less than waiting that the maximum of setting up session allows the processing time), a session EO has been arranged, then current online session operand becomes 999, after waiting for that scheduling time then, can set up this session operation by rescheduling.
