Description
Technical field
The present invention relates to the QoS field, relate in particular to a kind of based on professional and User Priority QoS method for improving and system.
Background technology
Fast development along with mobile communication technology and Internet technology, Packet data service user demand based on the mobile network increases sharply day by day, how service quality (QoS, Quality ofService) ensures for the user provides end to end, becomes one of problem that each operator is concerned about most.
For the WCDMA system, when setting up packet data bearers, have only as travelling carriage (MS, Mobile Station), radio network controller (RNC, Radio Network Controller), service GPRS node (SGSN, Serving GPRS Support Node), each entity of gateway GPRS node (GGSN, GatewayGPRS Support Node) all supports consistent QoS characteristic, desired quality of service could finally embody in terminal applies.For the effective service quality of Control Network resource load and user grouping data service, the WCDMA system design QoS negotiation mechanism flexibly.
Specifically, at professional mounting phase, MS passes to SGSN by " activation PDP Context " message with the QoS grade of user's request, the SGSN QoS grade that decision can be supported based on self network resource status, and by " be given to GGSN before creating the PDP Context request information; GGSN also is low to moderate its based on the own resource situation with the QoS level down can support level; and return to SGSN; SGSN goes to the RNC entity before with this QoS grade subsequently; the QoS that carries out RAB consults by " creating the PDP Context response " message; as if Radio Resource situation anxiety then RNC will further reduce the QoS grade, at last by " renewal PDP Context " information updating SGSN, QoS grade on the GGSN entity, the unanimity of assurance end-to-end QoS characteristic.At professional sustained period, when network available resources anxiety or system load are excessive, MS or network side entity all may trigger the request that QoS consults, reduce the qos parameter of this service bearer by initiation " PDP context modification " message, satisfying under the prerequisite of basic function with the assurance system, is more user's service as much as possible.
Present stage, when the user used Packet data service in the WCDMA system, because the variation of network capabilities and resource load, " PDP context modification " message that the QoS negotiation mechanism support of system is initiated by terminal or network changed professional QoS grade.But the 3GPP standard has only considered that network capabilities reduces the QoS grade that is caused and descends at present, reckons without network capabilities and recovers QoS elevation scheme demand afterwards.
Therefore, in present system, when network available resources free time or system load alleviate, the request that MS and network side entity can initiatively not initiated the QoS lifting recovers the signatory QoS grade of user's request, this has just caused continuing along with business, the QoS grade may be more and more lower, and user experience constantly descends.If recover the QoS grade that original user contracts, then need MS to initiate once professional the connection again, but this can cause professional short interruption again.

Embodiment
The present invention mainly considers during the user grouping data service, under the improved scene of Internet resources or wireless environment, if be that the user provides business with lower QoS grade always, user experience is relatively poor on the one hand, and Internet resources also fail to be fully utilized on the other hand.Consider MS and do not know current network side resource situation, the present invention has designed the QoS negotiation mechanism that a kind of network side is initiated, and the entity of initiating the QoS negotiation can be the SGSN of core-network side or the RNC that inserts side.
The present invention is directed to existing WCDMA system, the problem that lacks necessary QoS elevation scheme between service period is improved, a kind of QoS machinery of consultation that is triggered by network side has been proposed, based on business and User Priority, promote the QoS grade of certain user's corresponding service, guarantee that simultaneously business procedure does not interrupt.
At first, definition user signatory User Priority parameter in HLR is Prior_u, and span is 1～Prior_u
Max, wherein 1 is limit priority, Prior_u
MaxBe lowest priority; Definition service priority parameter is Prior_s, and span is 1～Prior_s
Max, wherein 1 is limit priority, Prior_s
MaxBe lowest priority.
Simultaneously, definition list item [User_ID, Service_Type] expression user ID and the corresponding type of service of using, [Prior_u, Prior_s] be list item [User_ID, Service_Type] pairing User Priority and corresponding service priority, and the definition user is to should professional [User_ID, Service_Type] request QoS class parameter be " QoS_R ", the former consulting service quality class parameter before not adopting QoS to promote is " QoS_N ".
Table 1 has provided the example of a business and User Priority parameter, and wherein the priority of conversation class (as speech), interactive class (as real-time recreation), stream class (as video request program), background class traffic (downloading as FTP) is respectively 1,2,3,4, reduces step by step.

| 1 | 1 | [1，1] | [1，2] | [1，3] | [1，4] |
| 2 | 3 | [3，1] | [3，2] | [3，3] | [3，4] |
| 3 | 2 | [2，1] | [2，2] | [2，3] | [2，4] |
| ... | ... | ... | ... | ... | ... |
| N | Prior_u | [Prior_u，1] | [Prior_u，2] | [Prior_u，3] | [Prior_u，4] |
For fear of the continuous dynamic change of system resource, cause the qos parameter of system frequent table tennis lifting to occur and reduce, can introduce solution based on hesitation.
Network side entity SGSN or RNC detect by periodic resource, if the system of discovery available resources parameters R is higher than the triggering thresholding R of QoS elevation scheme
ThresholdThe time, i.e. R＞R
Threshold, will start timer Timer and carry out timing; If R≤R
Threshold, then stop timer immediately.Reach the timer upper limit T that presets as Timer
TriggerThe time (illustrate in nearly a period of time, system's available resources situation all be higher than trigger thresholding), trigger QoS and promote testing process, simultaneously timer is made zero, restart timing.Wherein, carry out the triggering thresholding R of QoS elevation scheme
ThresholdBe higher than and carry out the triggering thresholding that QoS reduces mechanism in the existing WCDMA system, have a difference with reducing between the thresholding, avoid system QoS that frequent table tennis takes place and promote and reduction with the lifting thresholding that guarantees system QoS.
SGSN or RNC will initiate to comprise the inquiry of following parameter to HLR: the request QoS grade " QoS_R " of the type of service " Service_Type " of User Priority " Prior_u ", each PDP Context of user, service priority " Prior_s ", user's current business, the negotiation QoS grade " QoS_N " of user's current business.Direct interface Gr is arranged between SGSN and the HLR, can directly initiate parameter request to HLR; And no direct interface between RNC and the HLR, RNC need initiate parameter query to HLR through SGSN, and promptly RNC obtains these query arguments indirectly.
After SGSN or RNC obtain above-mentioned parameter, promote testing process with starting based on professional QoS with User Priority.According to the relation between service priority and the User Priority, testing process can be divided into following two kinds of schemes.
(1) at first considers the service priority scheme
This scheme is at first considered professional priority level when selecting to carry out the user of QoS lifting, idiographic flow comprises as shown in Figure 1:
(2) at first consider the User Priority scheme
This scheme is at first considered the user priority grade when selecting to carry out the user of QoS lifting, idiographic flow comprises:
Step 2 is selected the user of satisfy condition " QoS_N＜QoS_R " from User Priority is the list item (being the highest customer group of present User Priority) of Prior_u, the list item that it is corresponding [User_ID, Service_Type] constitutes set I;
Step 3 in set I, is selected the list item that service priority is Prior_s (i.e. the business of the present limit priority of this customer group), constitutes subclass S;
Step 4 judges whether S set is empty, if, execution in step five, otherwise execution in step eight;
Step 5 judges whether Prior_s=Prior_smax sets up, if, execution in step six, otherwise, Prior_s=Prior_s+ 1, execution in step three;
Step 6 judges whether Prior_u=Prior_umax sets up, if, execution in step seven, otherwise, Prior_u=Prior_u+ 1, Prior_s=1, execution in step two;
Step 7, the corresponding professional QoS grade of all users has all reached optimum, temporarily need not to carry out QoS and promotes, and finishes this search routine, and S set is put sky;
Step 8, the corresponding service of list item among the pair set S [User_ID, Service_Type] respective user are carried out QoS and are promoted, and S set is put sky.
The QoS elevation scheme of the present invention's design comprises two kinds of application scenarioss: the one, and SGSN promotes based on the QoS of resources of core network and load variations initiation, and another kind is the QoS lifting of RNC based on access network resource and wireless environment variation initiation.
(1) the QoS elevation scheme of SGSN initiation
The SGSN node periodically carries out network resource status and detects, if find that at a time excited user number reduces in the network, system load diminishes and makes the network available resources be higher than the triggering thresholding of QoS elevation scheme (as after at 22 in evening, enter professional relatively idle period), system can be under the situation that the user need not to participate in, promote negotiation by the qos parameter between SGSN triggering and the MS, send the request of upgrading PDP Context, some business for current excited users under the unbroken prerequisite of business provides the QoS of higher level to ensure, promote user experience, effectively utilize Internet resources simultaneously.The QoS elevation scheme that SGSN initiates as shown in Figure 2.
This flow process promotes testing process by what the SGSN entity was initiated based on professional QoS with User Priority, when periodically detecting core net network available resources and load state and improve, triggers SGSN and attempts carrying out QoS and promote and consult, and concrete message flow is as follows:
Step 21, SGSN promotes testing process based on professional QoS with User Priority, selects the user ID and the corresponding business type that need lifting;
Step 22, SGSN sends RAB (Radio Access Bearer, RAB) to RNC and revises request, wherein comprises the QoS grade " QoS_N1 " that the SGSN suggestion is supported;
Step 23, RNC returns RAB to SGSN and revises response according to the Radio Resource situation, and its QoS grade is the QoS grade " QoS_N2 " that can support after RNC confirms;
Step 24, SGSN sends the PDP Context request of upgrading, and consults qos parameter with GGSN;
Step 25, GGSN carries out QoS to be consulted, and returns to SGSN and upgrades the PDP Context response, and its QoS grade is the QoS grade " QoS_N3 " that can support after GGSN confirms;
Step 26, SGSN presses qos parameter and selects Radio priority level and data flow ID (PFI, Packet FlowID), sends the PDP Context request of revising to MS;
Step 27 is if the QoS grade after MS accepts to consult then sends the modification PDP Context to SGSN and accepts; If MS does not accept this QoS grade, then initiate deexcitation PDP Context process.
According to top description, after the QoS lifting flow process through the SGSN initiation, the pass between each qos parameter is: QoS_N≤QoS_N3≤QoS_R.Therefore, adopt QoS to promote after the flow process, this user's corresponding service has obtained better QoS grade.
(2) the QoS elevation scheme of RNC initiation
The RNC node periodically carries out network resource status and detects, if at a time finding the trigger gate that the RAB number of users reduces, system load diminishes makes the network available resources be higher than the QoS elevation scheme prescribes a time limit, system can be under the situation that the user need not to participate in, by the negotiation again of carrying out qos parameter between RNC triggering and the MS, send the request that QoS promotes, revise its PDP Context, guaranteeing under professional unbroken prerequisite, for customer service provides higher QoS level other service, increase the utilance of on-air radio resource simultaneously.
Fig. 3 shows the QoS lifting flow process that RNC initiates, and concrete message flow is as follows:
Step 31, RNC promotes testing process based on professional QoS with User Priority, selects the user ID and the corresponding business type that need lifting;
Step 32, RNC sends RAB (Radio Access Bearer, RAB) to SGSN and revises request, wherein comprises the QoS grade " QoS_N1 " that the RNC suggestion is supported;
Step 33, SGSN returns RAB to RNC and revises response according to the resources of core network situation, and its QoS grade is the QoS grade " QoS_N2 " that can support after SGSN confirms;
Step 34, SGSN sends the PDP Context request of upgrading, and consults qos parameter with GGSN;
Step 35, GGSN carries out QoS to be consulted, and returns to SGSN and upgrades the PDP Context response, and its QoS grade is the QoS grade " QoS_N3 " that can support after GGSN confirms;
Step 36, SGSN presses qos parameter and selects Radio priority level and data flow ID (PFI, Packet FlowID), sends the PDP Context request of revising to MS;
Step 37 is if the QoS grade after MS accepts to consult then sends the modification PDP Context to SGSN and accepts; If MS does not accept this QoS grade, then initiate deexcitation PDP Context process.
According to top description, after the QoS elevation scheme through the RNC initiation, the relation between each qos parameter is: QoS_N≤QoS_N3≤QoS_R.Therefore, adopt QoS to promote after the flow process, this user's corresponding service has obtained better QoS grade.
Those skilled in the art can also carry out various modifications to above content under the condition that does not break away from the definite the spirit and scope of the present invention of claims.Therefore scope of the present invention is not limited in above explanation, but determine by the scope of claims.
