Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
The embodiment of the present application provides a kind of method for handling message, and this method can be applied to the management CP in BRAS.
BRAS includes CP and at least one UP.In the embodiment of the present invention, the CP in BRAS can be divided into multiple virtual CP (alternatively referred to as
Virtual BRAS).Multiple virtual CP can be divided into static CP, interim CP and management CP.Wherein, static CP is fixed allocation to a certain UP
Virtual CP；Interim CP is to be allocated temporarily to the virtual CP that UP handles online request message when the corresponding virtual CP overload of UP；
CP is managed for the resource utilization according to the corresponding each virtual CP of UP, it is determined whether distribute interim CP for UP.
Fig. 1 is system framework figure provided by the embodiments of the present application, as shown in Figure 1, the system may include BRAS, user's end
End 1 and user terminal 2.BRAS may include the corresponding static state CP2 of corresponding static state CP1, the UP2 of management CP, UP1, UP2, UP1 and
Interim CP resource pool.It wherein, include interim CP1 and interim CP2 in interim CP resource pool.User terminal 1 and user terminal 2 are distinguished
It is connected with UP1, UP2, UP1, UP2, static state CP1, static state CP2, interim CP1, interim CP2 are connected with management CP, and UP1 is for handling
The message of user terminal in region 1, message of the UP2 for user terminal in processing region 2.When management CP detects UP1 to quiet
When state CP1 sends the online request message of user terminal 1, it can be determined that it is preset whether the resource utilization of static CP1 is greater than
Resource utilization threshold.If the resource utilization of static state CP1 is greater than preset resource utilization threshold, CP is managed interim
Not used interim CP1 is determined in CP resource pool, and sends the first redirection message to UP1.Wherein, in the first redirection message
Carry the mark of interim CP1.UP1 receives the first redirection message, the online request message for then sending user terminal 1
It is forwarded to interim CP1.
It is detailed to a kind of method progress for handling message provided by the embodiments of the present application below in conjunction with specific embodiment
Explanation, as shown in Fig. 2, specific step is as follows.
Step 201, when detecting online request message of the first UP to the first CP transmission user terminal, judge the first CP
Resource utilization whether be greater than preset resource utilization threshold.
Wherein, the first CP is to manage the CP that CP is the first UP distribution.
In an implementation, when user terminal needs to be linked into network, user terminal can be to the UP in its affiliated area (i.e.
First UP) send online request message.It, can be online by this after first UP receives the online request message of user terminal transmission
Request message is forwarded to the CP (i.e. the first CP) of currently processed online request message.
Wherein, the first CP can be the static CP that management CP is the first UP distribution, be also possible to manage CP for the first UP points
The interim CP matched.For example, if the resource utilization that management CP is the first static state CP of the first UP distribution is not more than preset resource
Using threshold value, then when the first UP receives the online request message of user terminal transmission, online request message is sent to
First static state CP, the first static state CP are CP, i.e. the first CP of currently processed online request message, and managing CP at this time is the first UP
The CP of distribution is the first static state CP.If the resource utilization for managing the first static state CP that CP is the first UP distribution is greater than preset money
Source utilization rate threshold value then manages CP for interim CP1 and distributes to the first UP, at this point, including in CP of the management CP for the first UP distribution
First static state CP and interim CP1 reports online request when the first UP receives the online request message of user terminal transmission
Text is sent to interim CP1, which is CP, i.e. the first CP of currently processed online request message, and managing CP at this time is first
The CP of UP distribution is the first static state CP and interim CP1.
Management CP in resource utilization threshold can be stored in advance, the resource utilization threshold can by technical staff according to
Experience is configured.For example, the resource utilization threshold of CP can be arranged by way of order in technical staff in management CP
It is 80%.Wherein, command format can be：vbras resource-limit80.Managing CP can be with the first UP of real-time detection
The no online request message that user terminal is sent to the first CP, when management CP detects that the first UP sends user terminal to the first CP
Online request message when, judge whether the resource utilization of the first CP is greater than or equal to preset resource utilization threshold.Such as
Fruit is then to illustrate the first CP overload, can not handle the online request message, and management CP executes step 202.Otherwise, illustrate first
CP does not overload, can handle the online request message.Wherein, the resource of the first CP may include the memory of the first CP, centre
Managing device (Central Processing Unit, CPU) etc. influences the resource of the first CP treatment effeciency.
Step 202, if the resource utilization of the first CP is greater than preset resource utilization threshold, in interim CP resource
Not used first interim CP is determined in pond, and sends the first redirection message to the first UP, is carried in the first redirection message
There is the mark of the first interim CP, so that the first UP sends online request message to the first interim CP.
In an implementation, if the resource utilization of the first CP is greater than or equal to preset resource utilization threshold, CP is managed
The interim CP being not used by (the i.e. first interim CP) can be randomly choosed in interim CP resource pool handles online request report
Text, and the first redirection message is sent to the first UP.Wherein, the mark of the first interim CP can be carried in the first redirection message
Know.CP is managed in interim CP resource pool after selected first interim CP, it can be by the corresponding relationship of the first UP and the first interim CP
It stores into the mapping table of UP and CP, to prevent follow-up management CP from the first interim CP is distributed to other UP.Correspondingly, pipe
When reason CP selects interim CP in interim CP resource pool, it can also determine that is be not used by faces according to the mapping table of UP and CP
When CP.
After first UP receives the first redirection message, the first interim CP can be set to processing access request message
CP, it is subsequent, when the first UP receives the online request message of user terminal transmission, online request message can be forwarded to the
One interim CP.First interim CP is according to online request message to certificate server (such as AAA
(AuthenticationAuthorizationAccounting, verifying authorization book keeping operation) server) send certification request.Wherein,
The corresponding authentication information of user terminal is carried in certification request.If certification passes through, the first interim CP can pass through the first UP
It notifies user terminal online, and access control is carried out to user terminal, meanwhile, certificate server can open the user terminal
The operation such as charging.After user terminal is online, the first interim CP can also generate user management list item, and be sent to the first UP.The
After one UP receives user management list item, hardware forwarding table item can be generated according to user management list item.It is subsequent, when the first UP connects
When receiving the service message of user terminal transmission, the service message can be forwarded according to hardware forwarding table item.
It should be noted that if user terminal is that dynamic subscriber can after the first interim CP receives online request message
To parse to online request message, the user terminal informations such as the physical location of user terminal are obtained.Then, the first interim CP
The corresponding authentication information (such as username and password) of user terminal can be generated according to user terminal information, and to authentication service
Device sends certification request.Wherein, the corresponding authentication information of user terminal can be carried in the certification request.
If user terminal is static subscriber, after the first interim CP receives online request message, available user is whole
Corresponding preconfigured authentication information is held, and sends certification request to certificate server.Wherein, it can be taken in the certification request
With the corresponding authentication information of user terminal.
The method of processing message provided by the present application turns to introduce interim CP resource pool in control separation networking in BRAS, can
It realizes that BARS system according to network service dynamic change dynamic adaptation resource, effectively copes with mobile network's tidal effect, realizes
Distribution according to need promotes resource utilization, and intelligence is coped with a large amount of network service bursts or migrated, and mitigates the same of operator's networking cost
When construct high-efficiency network.
Optionally, management CP can first judge in interim CP resource pool with the presence or absence of the interim CP not used by other UP.
Then, corresponding step is executed further according to judging result, concrete processing procedure is as follows.
Judging result one executes if there are not used interim CP in interim CP resource pool in interim CP resource pool
The step of middle determination not used first interim CP.
In an implementation, if there is the interim CP not used by other UP in interim CP resource pool, managing CP can be
Not used first interim CP is determined in interim CP resource pool, and concrete processing procedure is detailed in step 202, and details are not described herein again.
It optionally, can be preset after management CP determines not used first interim CP in interim CP resource pool
In the mapping table of UP and CP, the list item of the corresponding relationship of the first UP and the first interim CP is added.
It in an implementation, can be by first after managing CP determining not used first interim CP in interim CP resource pool
The corresponding relationship of the interim CP of UP and first is added in the mapping table of preset UP and CP.Managing CP can be with real-time detection
For the resource utilization of the CP of the first UP distribution, and the resource utilization of the CP of distribution is stored in the mapping table of UP and CP
In.The mapping table can be as shown in Table 1.
Table one
Judging result two, if not used interim CP is not present in interim CP resource pool, what is distributed for the first UP
The 2nd minimum CP of resource utilization is determined in CP, is sent the second redirection message to the first UP, is taken in the second redirection message
Mark with the 2nd CP, so that the first UP sends online request message to the 2nd CP.
In an implementation, if there is no the interim CP not used by other UP in interim CP resource pool, managing CP can be with
The minimum CP (i.e. the 2nd CP) of resource utilization is selected to handle online request message in the CP distributed for the first UP, and to first
UP sends the second redirection message.Wherein, the mark of the 2nd CP can be carried in the second redirection message.In this way, the first UP
After receiving the second redirection message, the 2nd CP can be set to the CP of processing access request message, subsequent, the first UP is received
After the online request message sent to user terminal, online request message can be forwarded to the 2nd CP.
It optionally, can be into if managing CP if the resource utilization of the first CP is greater than preset resource utilization threshold
One step is judged as whether the resource utilization of other CP of the first UP distribution is all larger than preset resource utilization threshold.If it is
The resource utilization of other CP of the first UP distribution is all larger than preset resource utilization threshold, then executes in interim CP resource pool
The interim CP step of middle determination not used first.It is preset if it is being less than in other CP of the first UP distribution there are resource utilization
Resource utilization threshold CP, then send third redirection message to the first UP, carry third in third redirection message
The mark of CP, so that the first UP sends online request message to the 3rd CP, the 3rd CP is provided in other CP distributed for the first UP
The minimum CP of source utilization rate.
In an implementation, preset resource utilization threshold is all larger than if it is the resource utilization of other CP of the first UP distribution
Value, then explanation is that other CP of the first UP distribution can not handle online request message, and management CP can be in interim CP resource pool
The interim CP of middle determination not used first, concrete processing procedure are detailed in step 202, and details are not described herein again.
CP in other CP distributed if it is the first UP there are resource utilization less than preset resource utilization threshold,
Then explanation is the presence of the CP that can handle online request message in other CP of the first UP distribution.Correspondingly, management CP can be
Online request message is handled for the minimum CP (i.e. the 3rd CP) of selection resource utilization in other CP of the first UP distribution, and to the
One UP sends third redirection message.Wherein, the mark of the 3rd CP can be carried in third redirection message.In this way, first
After UP receives third redirection message, the 3rd CP can be set to the CP of processing access request message, subsequent, the first UP connects
After the online request message for receiving user terminal transmission, online request message can be forwarded to the 3rd CP.For the first UP distribution
Other CP may include manage CP be the first UP distribution static CP, can also include management CP be the first UP distribution it is interim
CP。
Optionally, management CP can also discharge the first interim CP when the first interim CP meets preset condition, specific to locate
Reason mode can be as follows.
Mode one discharges the first interim CP if the corresponding user terminal of the first interim CP is offline.
In an implementation, if the user terminal accessed on the first interim CP is all offline, illustrate that the first interim CP is in
Idle state, at this point, management CP can discharge the first interim CP, so that the first interim CP is distributed to others by follow-up management CP
UP is used.
Mode two sends the upper of user terminal to the first interim CP if the first UP is not detected in default aging duration
Line request message then discharges the first interim CP, uses so that the first interim CP is distributed to other UP by follow-up management CP.
In an implementation, the corresponding aging duration of CP that promising first UP distribution can be stored in advance in CP is managed.The aging
Duration can be rule of thumb configured by technical staff.If management CP does not connect in the corresponding aging duration of the first interim CP
The online request message that the first UP sends user terminal to the first interim CP is received, then illustrates that the first interim CP is in idle shape
State makes at this point, management CP can discharge the first interim CP so that the first interim CP is distributed to other UP by follow-up management CP
With.For example, as shown in Table 2, when the first interim CP corresponding aging, is 20 hours a length of, if management CP was at continuous 20 hours
It does not receive the online request message that the first UP sends user terminal to the first interim CP inside, then discharges the first interim CP.
Table two
| UP title | Static CP/ resource utilization | Interim CP/ resource utilization | Aging duration |
| First UP | First static state CP/80% | First interim CP/40% | 20 hours |
| 2nd UP | Second static state CP/60% | --- | --- |
It should be noted that if the first interim CP is currently processed online request message in the CP for the first UP distribution
CP then manages CP after discharging the first interim CP.Management CP can select resource utilization most in the CP distributed for the first UP
Low CP (i.e. the 4th CP) handles online request message, and sends the 4th redirection message to the first UP.Wherein, it the 4th redirects
The mark of the 4th CP can be carried in message.In this way, the 4th CP can be set after the first UP receives the 4th redirection message
It is set to the CP of processing access request message, it is subsequent, after the first UP receives the online request message of user terminal transmission, it can incite somebody to action
Online request message is forwarded to the 4th CP.
Optionally, management CP can be that the first UP distributes interim CP according to current time.Concrete processing procedure is as follows.Work as inspection
When measuring current time and being in preset first time range, in the not used interim CP in interim CP resource pool, determine
The interim CP of first ratio, and the interim CP of the first ratio is distributed into the first UP.
In an implementation, the corresponding time range of each UP and allocation proportion can be previously stored with by managing in CP.The time model
Enclosing can be rule of thumb configured with allocation proportion by technical staff.When management CP detects that current time is in the first UP pairs
When the first time range answered, in the interim CP that can not used by other UP in interim CP resource pool of management CP, the is determined
The interim CP of one ratio, and the interim CP of the first ratio is distributed into the first UP.For example, the corresponding time range of the first UP is 9：
00 to 18：00, allocation proportion 80% includes 10 not used interim CP in interim CP resource pool, then when management CP detection
9 are in current time：00 to 18：When 00, management CP can select 8 interim CP to distribute to first in interim CP resource pool
UP.When management CP detects current time first time end of extent (EOE), management CP discharges these interim CP.In this way, management CP
It can be the first UP distribution first in the corresponding region of first time range according to the first time range belonging to current time
