Embodiment
Basic conception of the present invention is as follows:
In order to improve priority and the success rate of CDMA EV-DO QoS service access, promote the access impression of user QoS business, in the present invention, consider the user at once initiating QoS business to not initiating QoS business during this foundation after a connection setup, also priority access.
For this reason, the concept of an accurate QoS user is introduced herein.Described accurate QoS user refers to, user has consulted QoS attribute, but in this connection establishment, do not open the user of any QoS business.This kind of user has the ability initiating QoS business, although do not carry the information initiating QoS business in link information, has and very large after a connection setup, may will initiate QoS business immediately by ReservationOn.
Therefore, for accurate QoS user, should first allow its connecting system, observe a period of time, if at the appointed time, it has initiated QoS business by ReservationOn, then upgraded to real QoS user; If at the appointed time, it does not initiate QoS business, be then downgraded to BE user.In addition, if user, after changing, overload situations occurs, then need to discharge some accessed users to ensure that system load balances according to premature beats strategy.
On the basis of above-mentioned design, the present invention proposes a kind of QoS business access method, the following technical scheme of concrete employing:
When base station receives the connection request message of user, if judge that this user has consulted QoS attribute, and do not carry QoS information in the link information of this user, then it can be used as accurate QoS user, determine whether allow this accurate QoS user's access according to system current residual bandwidth.
Wherein, described link information comprises some information of internal system, such as Session information etc., whether user consults QoS attribute can be kept in the Session information of user, base station is when receiving the ConnectionRequest of user terminal, internal system can inquire about the Session information of this user, and whether will consult QoS attribute and get off as the transmission of an internal system field.
Further, described base station determines whether allow accurate QoS user to access in the following manner:
Judge whether system current residual bandwidth meets the minimum bandwidth needed for a user, if meet, then allow access; Otherwise, refusal access.
Further, if described base station allows described accurate QoS user's access, then described base station starting protection timer when accessing described accurate QoS user, if described accurate QoS user has initiated QoS business by ReservationOn in the timing cycle of described protection timer, be then QoS user by described accurate QoS customer upgrade; Otherwise, when arriving the timing cycle of described protection timer, described accurate QoS user is downgraded to BE user.
Further, described base station causes system overload after described accurate QoS user is downgraded to BE user, then discharge other BE users to meet the bandwidth needed for current BE user according to premature beats strategy, or directly discharges current BE user.
Further, described accurate QoS customer upgrade is cause system overload after QoS user by described base station, then discharge BE user to meet the bandwidth needed for current QoS user according to premature beats strategy.
Wherein, described premature beats strategy specifically comprises:
According to the QoS number of users thresholding of BE number of users thresholding and configuration and system current residual bandwidth, described base station judges whether system transships:
If the BE number of users accessed is more than or equal to BE number of users thresholding, then needs to find according to premature beats strategy and discharge at least one BE user to ensure that system load balances;
If the QoS number of users accessed equals the QoS number of users thresholding configured, then should refuse new QoS user's access;
If the current utilized bandwidth of system has been greater than system actual bandwidth, then need according to premature beats strategy find and release portion BE user to ensure that system load balances.
Further, described BE number of users thresholding can draw according to inverse bandwidth dynamic calculation, particularly, can adopt following algorithm:
BE number of users thresholding=(reverse total bandwidth-QoS CU bandwidth-accurate QoS CU bandwidth) minimum guarantee bandwidth of/BE;
Wherein, for each BE user, the inverse bandwidth taken because it is actual changes at any time, therefore, can configure a minimum bandwidth ensureing bandwidth to be used as shared by a BE user of BE according to backstage.
Wherein, QoS number of users thresholding is a Configuration Values.
Below in conjunction with the accompanying drawings and the specific embodiments the enforcement of technical solution of the present invention is described in further detail.
Fig. 1 shows the QoS service access device that the embodiment of the present invention provides, and as shown in Figure 1, this device mainly comprises user type identifier, acceptance judging device and accurate QoS user's protector, and the major function that each module realizes is described below:
User type identifier, is mainly used in when user's connection establishment, and differentiate the type of user, its concrete method of discrimination is as follows:
If this user does not consult QoS attribute, and does not carry QoS information in link information, then user type is BE user;
If this user has consulted QoS attribute, and does not carry QoS information in link information, then user type has been as the criterion QoS user;
If this user has consulted QoS attribute, and carries QoS information in link information, then user type has been QoS user.
Acceptance judging device, is mainly used in the user type identified according to user type identifier, adopts corresponding rule of receiving to carry out acceptance judging, to determine whether this user can access.
Its concrete acceptance judging method is as follows:
For BE user and QoS user, still whether allow to access this user according to original premature beats strategy decision;
For accurate QoS user, as long as system current residual bandwidth meets the minimum bandwidth needed for a user, then this user is allowed to access; Otherwise, refuse this user access.Wherein, system current residual bandwidth=oppositely total bandwidth-QoS CU bandwidth-accurate QoS CU bandwidth; And the minimum bandwidth needed for a user can draw according to test result, as a customer reverse minimal-overhead is about 11k.
Accurate QoS user's protector, is mainly used in: for the accurate QoS user accessed, and starts a protection timer, to ensure that user has time enough to initiate QoS application.Specifically be implemented as follows:
If user, in the timing cycle of protection timer, does not initiate QoS business by ReservationOn, then this user is downgraded to BE user;
If user, in the timing cycle of protection timer, has initiated QoS business by ReservationOn, be then QoS user by this customer upgrade.
Further, described acceptance judging device notifies described accurate QoS protector when accessing described accurate QoS user;
Described accurate QoS user's protector, when receiving the notice of described acceptance judging device, starts described protection timer.
In addition, if the bandwidth of applying for after being downgraded to BE user causes system overload, then needing according to premature beats strategy decision is directly discharge active user, or discharges other BE users to meet bandwidth needed for active user;
If applied for after upgrading to QoS user, more bandwidth causes system overload, then need according to premature beats strategy release BE user to meet the bandwidth needed for current QoS user.
Particularly, above-mentioned premature beats function is called overload control module to realize by acceptance judging device, this overload control module can be an independently module, also can be the submodule that acceptance judging device comprises, and only needs it to perform corresponding premature beats strategy.
Fig. 2 is the schematic flow sheet of the QoS business access method of the embodiment of the present invention, and as shown in Figure 2, this flow process specifically describes as follows:
Step 1., when user asks connection establishment, first judges that user type is BE, QoS or accurate QoS, if user type is BE or QoS user, then performs step 2; The QoS user if user type is as the criterion, then perform step 3;
If step 2. user type is BE or QoS user, then whether access this user according to premature beats strategy decision;
The QoS user if step 3. user type is as the criterion, then according to following formulae discovery system current residual bandwidth:
System current residual bandwidth=total bandwidth-QoS CU bandwidth-accurate QoS CU bandwidth,
If system current residual bandwidth is more than or equal to 11k, then allow this accurate QoS user's access, and starting protection timer; If system current residual bandwidth is less than 11k, then refuse user's access.
Fig. 3 shows the schematic diagram of the user type conversion of the embodiment of the present invention, and as shown in Figure 3, the conversion of user type specifically comprises following content:
1) when after accurate QoS user's access, after opening QoS Business Stream by ReservationOn, user type changes QoS user into;
2) when after accurate QoS user's access, in the protection timer of accurate QoS user's protector, do not open flow operation, then, after timer expiry, be downgraded to BE user;
3) BE user and QoS user can turn mutually by opening stream and closing stream;
4) BE user and QoS user change the QoS user that is as the criterion never.Accurate QoS user is the transitory state of user when accessing.
Below in conjunction with embody rule example of the present invention, the present invention is further described in detail.
Suppose that current system total bandwidth be 1000K, QoS CU bandwidth is 900K, accurate QoS user is 55K.A BE user ensures that bandwidth is 15K, and current to have accessed BE user be 3, then known BE CU total bandwidth is 45K.Now, system bandwidth is just finished.Now, an accurate QoS user asks access, and calculate and learn total bandwidth-QoS CU bandwidth-accurate QoS CU bandwidth=45K, be greater than 11K, therefore, this accurate QoS user can access, and takies 11K bandwidth.At this moment overall system bandwidth is instantaneous reaches 1011K, and instantaneous overload occurs.
If accurate QoS user initiates QoS business at once, then become QoS user, apply for that the bandwidth taken is 30K.Now, BE number of users thresholding is gone out according to following formulae discovery:
BE number of users thresholding=(reverse total bandwidth-QoS CU bandwidth-accurate QoS CU bandwidth) minimum guarantee bandwidth of/BE;
The BE number of users thresholding calculated is (1000-900-55-30)/15=1.And current BE number of users is 3.Therefore 2 users are had more in system.According to premature beats strategy, from three BE users, kick out of 2 users to ensure that system load balances.
If accurate QoS user does not initiate QoS business at once, then protect timer expiry, accurate QoS user becomes BE user.Then current BE number of users becomes 4.Recalculate BE number of users thresholding=(1000-900-55)/15=3.Then according to premature beats strategy, 1 BE user need be kicked out of to ensure that system load balances.
In sum, compared with prior art, the method realizing improving QoS success rate of business insertion of the present invention is the concept introducing accurate QoS user, make system temporarily can first access those and do not carry QoS information when connection establishment, and the user of QoS business will be initiated after a connection setup at once, which ensure that and follow-uply can successfully initiate QoS business.And can not because of being treated as the lower common BE user of priority and directly refusing its connecting system when connection establishment.Although instantaneous what access, the situation of total bandwidth overload may occur, and this time can control in smaller scope, and the situation of overload is also smaller, therefore obvious impact can not be caused on user's impression.Key of the present invention is the success rate of the QoS service access that improve under the peculiar flow process of CDMA EV-DO system.
These are only preferred case study on implementation of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
