As it is shown in figure 1, a kind of quality allocation method based on customer service speed that the embodiment of the present invention provides, including:
Step 101, SGSN receive the PDP activation process messages that user terminal sends.
When described user terminal needs to use session data traffic, described user terminal can to the described SGSN PDP activation process messages sent.
Step 102, receive described PDP activation process messages after, described SGSN obtain user terminal rate travel.
After described SGSN receives described PDP activation process messages, gather the Article 1 MR(MeasurementReport in rrc layer signaling, measurement report in RNC side) and Article 2 MR.Wherein said Article 1 MR and Article 2 MR is the MR that described user terminal reports to described RNC for nearest twice, MR contains described user terminal report MR on call time, obtain the first latitude and longitude information of described user terminal according to described Article 1 MR and described Article 2 MR and the second latitude and longitude information (such as utilizes MR to be estimated to each distance activating and concentrating community, recycling three-point fox method obtains user's latitude and longitude information, but method is not limited to this), the displacement of described user terminal is obtained further according to described first latitude and longitude information and described second latitude and longitude information.Described SGSN is according to calling time in a described MR and described 2nd MR and the displacement of described user terminal can calculate the rate travel of user terminal.
Step 103, according to the service rate of described user terminal and described rate travel, select bandwidth algorithm to obtain QoS bandwidth.
When user terminal needs to use session data traffic, described SGSN judges, according to described rate travel, moving scene that described user terminal is in and obtains described service rate, select different bandwidth algorithms according to described moving scene and described service rate, obtain QoS bandwidth.
It should be noted that, if user terminal uses session data traffic first, owing to history service speed does not also produce, the QoS bandwidth that therefore user terminal is asked to network side can be: the maximum up QoS bandwidth of described user terminal and network side signing and maximum downstream QoS bandwidth.
Step 104, set up PDP Context according to described QoS bandwidth, in order to described user terminal conversates data service.
SGSN obtains QoS bandwidth by described step 103 and GGSN holds consultation and sets up PDP Context, obtain setting up PDP Context success message, SGSN receive described set up PDP Context success message after, QoS bandwidth will be obtained by described step 103 to hold consultation with RNC, set up RAB carrying, obtain setting up RAB success message.Wherein, in the described process setting up RAB carrying, described carrying foundation is not likely to be one step completed, when setting up unsuccessful first, described QoS bandwidth can be carried out degradation according to the QoS destaging algorithms that current network is given and calculate by described SGSN, again will be held consultation with RNC by another QoS bandwidth calculated of demoting, till consulting to be successfully established RAB carrying.Wherein, due to service rate according to described user terminal and described rate travel in step 103, select bandwidth algorithm dynamically, then can obtain being suitable for the QoS bandwidth of current network, ensure that the QoS once success consulted to greatest extent, save a large amount of unnecessary system resource carrying out QoS bandwidth taking required for degradation calculating and redundancy QoS negotiation, improve system effectiveness.SGSN receives RAB and carries the message that is successfully established, and sends PDP activation success message to described user terminal, and described user terminal receives after element searches PDP activation success message, and conversate data service.After the session data traffic of described user terminal carries out, initiating PDP deexcitation process messages to SGSN, described SGSN obtains the speed of this session data traffic and stores.
A kind of quality allocation method based on customer service speed of embodiment of the present invention offer and device, the rate travel of user terminal is obtained by SGSN, service rate according to described user terminal and described rate travel, obtain QoS bandwidth, and then set up PDP Context, in order to described user terminal conversates data service.The program without directly distributing to user terminal by the maximum bandwidth of signing as prior art, thus decreasing because bandwidth deficiency causes that repeatedly QoS consults, takies unnecessary bandwidth resources, and the problem that the utilization rate of system resource is low.
So that those skilled in the art are better understood from the technical scheme that the embodiment of the present invention provides, existing a kind of quality allocation method based on customer service speed that further embodiment of this invention is provided is described in detail.

If collecting Article 1 MR and Article 2 MR, performing step 203, if not collecting MR, thinking that described user terminal asks PDP activation first, performing step 215.
Wherein said Article 1 MR and Article 2 MR be described user terminal nearest twice to the RNC MR reported.Described RRC comprises a plurality of described MR.Described MR contain described user terminal report MR to RNC on call time.
Step 203, according to calling time on Article 1 MR and Article 2 MR comprise and the displacement of described user terminal obtains the rate travel of described user terminal.
Concrete, the first latitude and longitude information of described user terminal is obtained according to described Article 1 MR, the second latitude and longitude information of described user terminal is obtained according to described Article 2 MR, described first latitude and longitude information and described second latitude and longitude information are carried out mathematic interpolation, obtains the displacement of described user terminal.
Described Article 1 MR comprises the first of described user terminal is called time, described Article 2 MR comprises the second of described user terminal is called time, by call time on described first with described second on call time and carry out mathematic interpolation, obtain described user terminal and report the interval between described Article 1 MR and described Article 2 MR.
Described displacement and described interval are carried out division calculation, obtains the rate travel of described user terminal.
Step 204, the rate travel of described user terminal and rate travel threshold value are compared, if described rate travel is less than or equal to described rate travel threshold value, then the moving scene of described user terminal is that low-speed motion scene performs step 205, otherwise performs step 210 for high motion scenes.
Wherein, described rate travel threshold value is default.
Step 205, obtain from session data traffic first to the average traffic speed of the N-1 time session data traffic, and the service rate of n-th session data traffic.
Wherein, in SGSN, session data traffic speed, business number of times and corresponding relation therebetween are stored by memorizer, concrete, with the session speed of n-th for RNForm storage.
Wherein, N is the positive integer more than 0, and described average traffic speed from session data traffic first to the N-1 time session data traffic isThe service rate of described n-th session data traffic is RN。
Described SGSN also includes deletion user's intervalometer, for regularly deleting the session data traffic speed of storage in described depositor.Such as, the set of time deleting user's intervalometer is 24 hours, the session data traffic speed of storage in during this period of time described depositor is reset in every 24 hours.After the session data traffic speed that will store in depositor resets, the first time session service that user carries out is as session data traffic first, and the service rate of its correspondence is session data traffic speed first.
Step 206, obtain n-th session data traffic QoS bandwidth BWN。
In order to obtain the QoS bandwidth of n-th session data traffic, SGSN needs to be recorded preserving to the PDP once the set up bandwidth information connected, in order to use.
Wherein, described RNActual speed rate for n-th session data traffic.Owing to expense (such as redundant data occupied bandwidth) can be produced at data transmission procedure, therefore this RNIt is typically smaller than BWN。
Step 207, by the average traffic speed of described front N-1 session data trafficService rate R with described n-th session data trafficNCompare, if described inLess than or equal to RNThen perform step 208, otherwise perform step 209.
Step 208, according to described BWNCarry out positive correlation calculating with stepping ratio, obtain a QoS bandwidth.
Afterwards, step 216 is performed.
Oneth QoS bandwidth specifically can include a upstream bandwidth and a downlink bandwidth.If the PDP activation process messages of presently described user terminal requests is to set up the N+1 time session data traffic, the upstream bandwidth of a concrete described QoS bandwidth and the calculating process of downlink bandwidth are as follows:
A QoS upstream bandwidth is obtained according to formula (1):
BWUL_MaxBitRate_N+1=BWUL_MaxBitRate_N*(1+△BWUP1)(1)
A QoS downlink bandwidth is obtained according to formula (2):
BWDL_MaxBitRate_N+1=BWDL_MaxBitRate_N*(1+△BWUP1)(2)
Wherein, BWUL_MaxBitRate_N+1For the upstream bandwidth of request, BW required for this session data trafficDL_MaxBitRate_N+1For the downlink bandwidth of request, BW required for this session data trafficUL_MaxBitRate_NFor the upstream bandwidth of n-th session data traffic, BWDL_MaxBitRate_N+1For the downlink bandwidth of n-th session data traffic, △ BWUP1For the stepping ratio that bandwidth promotes.
Step 209, according to described BWNCarry out negative correlation calculating with stepping ratio, obtain the 2nd QoS bandwidth.
Afterwards, step 216 is performed.
2nd QoS bandwidth specifically can include a upstream bandwidth and the bandwidth that rolls off the production line.If the PDP activation process messages of presently described user terminal requests is to set up the N+1 time session data traffic, concrete described 2nd QoS bandwidth computation process is as follows:
The 2nd QoS upstream bandwidth is obtained according to formula (3):
BWUL_MaxBitRate_N+1=BWUL_MaxBitRate_N*(1-△BWDown1)(3)
A QoS downlink bandwidth is obtained according to formula (4):
BWDL_MaxBitRate_N+1=BWDL_MaxBitRate_N*(1-△BWDown1)(4)
Wherein, BWUL_MaxBitRate_N+1For the upstream bandwidth of request, BW required for this session data trafficDL_MaxBitRate_N+1For the downlink bandwidth of request, BW required for this session data trafficUL_MaxBitRate_NFor the upstream bandwidth of n-th session data traffic, BWDL_MaxBitRate_N+1For the downlink bandwidth of n-th session data traffic, △ BWDown1For the stepping ratio that bandwidth declines.
To be combined by the 2nd QoS upstream bandwidth and the 2nd QoS downlink bandwidth that formula (3) and formula (4) obtain, obtain described 2nd QoS bandwidth.
By the description of above-mentioned steps 205 to 209, SGSN obtains the average traffic speed of front N-1 session data trafficAnd the service rate R of n-th session data trafficN, and compare RNWithIf described inLess than or equal to RN, then service rate has the trend of increase, is therefore that a QoS bandwidth of the N+1 time session distribution can increase to some extent than the bandwidth of n-th session, as shown in formula (1) (2).On the other hand, described inMore than RN, then service rate has the trend of reduction, is therefore that a QoS bandwidth of the N+1 time session distribution can reduce to some extent than the bandwidth of n-th session, as shown in formula (3) (4).Wherein formula (1), △ BW in (2)UP1, and the △ BW in formula (3), (4)Down1Concrete value, it is possible to according to real network situation, being selected by the experiment of limited number of time, it is not specifically limited by the embodiment of the present invention.
Step 210, obtain the service rate of the N-1 time session data traffic and the service rate of n-th session data traffic.
Wherein, N is the positive integer more than 0, and the service rate of described the N-1 time session data traffic is RN-1, the service rate of described n-th session data traffic is RN。
Step 211, obtain n-th session data traffic QoS bandwidth BWN。
Wherein, the QoS bandwidth of described n-th session data traffic is BWN, described BWNUpstream bandwidth and downlink bandwidth including n-th session data traffic.
Step 212, by the service rate R of described the N-1 time session data trafficN-1Service rate R with described n-th session data trafficNCompare, if described RN-1Less than or equal to RNThen perform step 213, otherwise perform step 214.
Step 213, according to described BWNCarry out positive correlation calculating with stepping ratio, obtain the 3rd QoS bandwidth.
Afterwards, step 216 is performed.
3rd QoS bandwidth specifically can include a upstream bandwidth and the bandwidth that rolls off the production line.If the PDP activation process messages of presently described user terminal requests is to set up the N+1 time session data traffic, concrete described 3rd QoS bandwidth computation process is as follows:
The 3rd QoS upstream bandwidth is obtained according to formula (5):
BWUL_MaxBitRate_N+1=BWUL_MaxBitRate_N*(1+△BWUP2)(5)
The 3rd QoS downlink bandwidth is obtained according to formula (6):
BWDL_MaxBitRate_N+1=BWDL_MaxBitRate_N*(1+△BWUP2)(6)
Wherein, BWUL_MaxBitRate_N+1For the upstream bandwidth of request, BW required for this session data trafficDL_MaxBitRate_N+1For the downlink bandwidth of request, BW required for this session data trafficUL_MaxBitRate_NFor the upstream bandwidth of n-th session data traffic, BWDL_MaxBitRate_N+1For the downlink bandwidth of n-th session data traffic, △ BWUP2For the stepping ratio that bandwidth promotes.
To be combined by the 3rd QoS upstream bandwidth and the 3rd QoS downlink bandwidth that formula (5) and formula (6) obtain, obtain described 3rd QoS bandwidth.
Step 214, according to described BWNCarry out negative correlation calculating with stepping ratio, obtain the 4th QoS bandwidth.
Afterwards, step 216 is performed.
4th QoS bandwidth specifically can include a upstream bandwidth and the bandwidth that rolls off the production line.If the PDP activation process messages of presently described user terminal requests is to set up the N+1 time session data traffic, concrete described 4th QoS bandwidth computation process is as follows:
The 4th QoS upstream bandwidth is obtained according to formula (7):
BWUL_MaxBitRate_N+1=BWUL_MaxBitRate_N*(1-△BWDown2)(7)
A QoS downlink bandwidth is obtained according to formula (8):
BWDL_MaxBitRate_N+1=BWDL_MaxBitRate_N*(1-△BWDown2)(8)
Wherein, BWUL_MaxBitRate_N+1For the upstream bandwidth of request, BW required for this session data trafficDL_MaxBitRate_N+1For the downlink bandwidth of request, BW required for this session data trafficUL_MaxBitRate_NFor the upstream bandwidth of n-th session data traffic, BWDL_MaxBitRate_N+1For the downlink bandwidth of n-th session data traffic, △ BWDown2For the stepping ratio that bandwidth declines.
In the present embodiment, described △ BWUP1With △ BWUP2、BWDown1With △ BWDown2Numerical value not necessarily identical, but in order to improve the success rate once setting up PDP Context in follow-up flow process, in the process obtaining QoS bandwidth, the stepping ratio that bandwidth declines is more than bandwidth rising stepping ratio.
By the description of above-mentioned steps 210 to 214, it is R that SGSN obtains the service rate of the N-1 time session data trafficN-1, the service rate of described n-th session data traffic is RN, and compare RN-1And RNIf, described RN-1Less than or equal to RN, then service rate has the trend of increase, is therefore that the 3rd QoS bandwidth of the N+1 time session distribution can increase to some extent than the bandwidth of n-th session, as shown in formula (5) (6).On the other hand, described RN-1More than RN, then service rate has the trend of reduction, is therefore that the 4th QoS bandwidth of the N+1 time session distribution can reduce to some extent than the bandwidth of n-th session, as shown in formula (7) (8).Wherein formula (5), △ BW in (6)UP2, and the △ BW in formula (7), (8)Down2Concrete value, it is possible to according to real network situation, being selected by the experiment of limited number of time, it is not specifically limited by the embodiment of the present invention.
Step 215, when described user terminal asks PDP activation first, described QoS bandwidth is initial Q oS bandwidth.Afterwards, step 216 is performed.
Described initial Q oS bandwidth is maximum up QoS bandwidth and the maximum downstream QoS bandwidth of described user terminal and network side signing.PDP activation is asked first due to user terminal, do not produce described history service speed, then think that now network side has the resource of abundance, can according to signing bandwidth information, directly it is allocated for user, the QoS bandwidth asking PDP activation to be asked first is only illustrated by the present embodiment with this kind of situation, and is not used to the present invention program is limited.
Step 216, SGSN consult to set up PDP Context to GGSN according to calculated QoS bandwidth.
Concrete, SGSN is carried and is consulted with GGSN by the calculated QoS bandwidth of above-mentioned steps, the 2nd QoS bandwidth, the 3rd QoS bandwidth, the 4th QoS bandwidth or initial Q oS bandwidth, to be reached for user terminal offer QoS guarantee, set up the purpose of PDP Context.
After step 216, SGSN and RNC consults to set up RAB carrying, sends to user and sets up PDP Context success message.
Concrete, described SGSN carries and carries out QoS negotiation by the calculated QoS bandwidth of above-mentioned steps, the 2nd QoS bandwidth, the 3rd QoS bandwidth, the 4th QoS bandwidth or initial Q oS bandwidth with RNC.If QoS consults successfully, then set up RAB carrying；If QoS consults unsuccessfully, then current QoS bandwidth is demoted by SGSN according to the QoS destaging algorithms of current network, again consults, until success.
User terminal sets up PDP Context success message according to what receive, uses session data traffic.
Further, in the another kind of implementation of the present invention, user terminal sends PDP deexcitation process messages to SGSN after using session data traffic complete.SGSN records this session data traffic speed after receiving described PDP deexcitation process messages.By recording conversation data service rate, it is simple to again set up PDP when connecting later, the historical record according to session data traffic speed, calculate first, second, third or the 4th QoS bandwidth.
The present invention judges the moving scene of user terminal by obtaining the rate travel of user terminal, if the translational speed that low-speed motion scene then illustrates user terminal is slow, now change of network environment is slow, and long-term historical session data service rate has reference value, so described in inciting somebody to actionWith RNCompare；If the translational speed that high motion scenes then illustrates user terminal is fast, now change of network environment fast (such as user terminal is likely to move to a slow network region from an express network region rapidly), changes in data rate amplitude is big, long-term historical session data service rate reference value is less, so the session data traffic speed that the session data traffic before N-1 session data traffic produces is not chosen, only by described RN-1With RNCompare.
A kind of quality allocation method based on customer service speed that the embodiment of the present invention provides, when user initiates PDP activation process messages, SGSN obtains user's rate travel, the one in bandwidth algorithm is dynamically selected according to rate travel, the session data traffic speed that user produces in session data traffic before is obtained according to the concrete bandwidth algorithm selected, and then obtain the QoS bandwidth that this user terminal needs, QoS negotiation is carried out according to this QoS bandwidth, thus ensure that between SGSN and GGSN, the success that QoS between SGSN and RNC consults, user is finally made successfully to activate PDP.Due to the present invention rate travel according to user terminal, dynamically select to need to calculate the service rate parameter of this QoS bandwidth, compared with directly distributing maximum signing bandwidth with prior art, more reasonably QoS bandwidth can be obtained, ensure that QoS consults successfully, also a saving system resource, improve system effectiveness, be finally successfully established PDP Context.
As it is shown on figure 3, the present invention provides a kind of mass distribution device based on customer service speed, including:
Receive unit 31, receive, for SGSN, the PDP activation process messages that described user terminal sends.
Rate travel acquiring unit 32, receive described SGSN after described PDP activation process messages for described reception unit 31 and obtain the rate travel of user terminal.
