Embodiment three,
For ease of better understanding the technical scheme of the embodiment of the invention, the embodiment of the invention provides a kind of network architecture diagram based on the SGSN pond, referring to Fig. 3-a, with RNC-1 be below the request user terminal A of adhering to select the process of SGSN be example, further describe.
Referring to Fig. 3-b, the method for a kind of Business Processing that the embodiment of the invention three provides can comprise:
301, the resource consumption index of each SGSN in the RNC-1 monitoring SGSN pond.
Wherein, the resource consumption index of each SGSN in the RNC-1 monitoring SGSN pond for example can comprise following resource consumption index at least a of each SGSN in the monitoring SGSN pond: adhered to number of users, activated PDP Context number and distributed bandwidth etc..Adhering to number of users, activate PDP Context number and to have distributed three resource consumption index such as bandwidth be that example describes with each SGSN in the RNC-1 monitoring SGSN pond in the present embodiment.
Under a kind of application scenarios, when user terminal need be asked network attachment, user terminal sent Attach Request message by RNC to SGSN, is attached to SGSN with request.RNC thus can be real-time in view of the above know the number of users that is attached to SGSN by it.
In actual applications, RNC-1 each SGSN in for example can corresponding SGSN pond is provided with one and has adhered to number of users counter C1, each of utilization setting adhered to number of users counter C1, real-time respectively statistics promptly counts the current actual user's number that adheres to by RNC-1 of each SGSN in the SGSN pond by the number of users that RNC-1 is attached to each SGSN.And monitor each SGSN in the SGSN pond by the number of users that RNC-1 adheres to based on this mode, need not existing network is changed, also need not to increase any signaling and just can realize, realize that cost is very little.
Under a kind of application scenarios, when the PDP Context of excited users terminal, the mutual signaling of RNC and SGSN, set up the Iu interface link for activating PDP Context, RAB (the RAB that is used to set up the Iu interface link that SGSN sends to RNC, Radio Access Bearer) can also carry the bandwidth information of distributing into this RAB in the assignment request message, whether RNC has enough resources according to current, determines whether to accept the request of SGSN.RNC thereby each SGSN of knowing that can be real-time in view of the above pass through the PDP Context number of its activation and the distribution bandwidth of each SGSN.
In actual applications, RNC-1 each SGSN in for example can corresponding SGSN pond is provided with one and has activated PDP Context counter C2, each of utilization setting activated PDP Context counter C2, the PDP Context number that real-time respectively each SGSN of statistics activates.
In actual applications, RNC-1 each SGSN in for example also can corresponding SGSN pond is provided with one and has distributed bandwidth counter C3, utilizes and has distributed bandwidth counter C3, the bandwidth that each SGSN of real-time respectively statistics has distributed.And monitor PDP Context number that each SGSN in the SGSN pond activates by RNC-1 and the bandwidth of having distributed based on this mode, need not existing network is changed, also need not to increase any signaling and just can realize, realize that cost is very little.
Be appreciated that RNC-1, can be than the resource consumption situation of each SGSN in the more comprehensive grasp SGSN pond by monitoring the above-mentioned various resource consumption index of each SGSN in the SGSN pond.
302, RNC-1 receives the Attach Request message of user terminal A.
When user terminal A need be attached to core net, user terminal A sent Attach Request message by the base station to RNC-1, and request is attached to SGSN; After RNC-1 receives the Attach Request message of user terminal A, start the algorithm flow of selecting SGSN for user terminal A.
303, RNC-1 calculates the current load ratio of each SGSN in the SGSN pond based on the monitoring result of current resource consumption index to each SGSN in the SGSN pond.
RNC-1 can be based on current adhering to number of users, activate PDP Context number and distributed the monitoring result of three resource consumption index such as bandwidth each SGSN in the SGSN pond, activate context number (following represent) and maximum bandwidth (following represent), the current resource consumption ratio of each SGSN in the calculating SGSN pond according to the maximum adhesion number of users of each SGSN in the SGSN pond (following represent), maximum activation PDP with Rb-max with Rp-max with Rs-max.
Wherein, webmaster in the network can pass through network management system, unified parameters such as maximum adhesion number of users, maximum activation PDP activation context number and maximum bandwidth for each SGSN in each RNC configuration SGSN pond of SGSN pond service are with the consistency of the SGSN parameter that keeps disposing among each RNC.Certainly, also can dispose above-mentioned SGSN parameter at each RNC in advance by alternate manner.
Further, consider under different situations, different resource consumption index may be not quite similar to the influence of SGSN load, and for example under some situation, the PDP Context number that activates of SGSN may be greater than adhering to number of users and having distributed the influence of bandwidth to the influence of SGSN load; In other cases, the bandwidth of distributing of SGSN may be greater than adhering to number of users and having activated the influence of PDP Context number to the influence of SGSN load, therefore, can be pre-configured in RNC the reference weight of (can by the unified configuration of webmaster) all kinds of resource consumption index, the computing formula of the load ratio of SGSN (following represent with Fb) can be as follows:
Fb＝(Rs/Rs-max)×ns+(Rp/Rp-max)×np+(Rb/Rb-max)×nb
Wherein, what Rs represented the current monitoring of RNC adheres to number of users, and ns represents that it is with reference to weight; Rp represents to activate the PDP Context number, and np represents that it is with reference to weight; Rb represents to distribute bandwidth, nb to represent that it is with reference to weight.Be understandable that, if ns=np=nb shows that then the reference weight of three resource consumption index is identical.
Be appreciated that the current load ratio of each SGSN in the SGSN pond that RNC-1 calculates based on aforesaid way is big more, its actual load ratio is also big more usually, and vice versa.
Further, if do not preset the reference weight of each resource consumption index in advance, then RNC-1 can calculate according to the reference weight of acquiescence, and wherein, the reference weight of the acquiescence of each resource consumption index can all be 1 for example.
304, RNC-1 is the SGSN of present load ratio minimum in the user terminal A SGSN pond selecting to calculate, sends the Attach Request message of user terminal A 1 to the SGSN that selects.
In actual applications, when the monitoring result of RNC-1 based on current resource consumption index to each SGSN in the SGSN pond, reference weight in conjunction with default resource consumption index, after calculating the current load ratio of each SGSN in the SGSN pond, the size of the load ratio that each SGSN that RNC-1 relatively calculates is current, the SGSN that the SGSN of present load ratio minimum adheres to as user terminal A in the SGSN pond of selecting to calculate.
Be understandable that, each RNC of SGSN pond service is based on the monitoring result of current resource consumption index to each SGSN in the SGSN pond, calculate the current load ratio of each SGSN in the SGSN pond, all be that each SGSN in the SGSN pond is with respect to the load ratio of this RNC, but also can objectively reflect the current load state of each SGSN in the SGSN pond, if each RNC of SGSN pond service all in the manner described above, the load ratio of each SGSN in monitoring and the calculating SGSN pond, and, also just can realize the load balancing of each SGSN in the SGSN pond on the whole for the SGSN of request its load ratio minimum that calculates of user terminal selecting of adhering to inserts.
In addition, under another kind of application scenarios, RNC-1 also can be based on the monitoring result of current resource consumption index to each SGSN in the SGSN pond, calculate the current resource residual amount of each SGSN in the SGSN pond, and the maximum SGSN of resource residual amount in the SGSN pond of selecting to calculate for user terminal A, to the Attach Request message of the SGSN transmission user terminal A of selecting 1.
In the specific implementation process of this scene, can be earlier the different reference priority of setting of each resource consumption index of monitoring, when selecting SGSN for user terminal A, RNC-1 can calculate with reference to the pairing surplus yield of the highest resource consumption index of priority, the SGSN that the SGSN that current resource residual amount is maximum in the SGSN pond that selection calculates adheres to as user terminal A, especially, if the highest surplus yield with reference to the priority correspondence is identical, then continue the relatively priority time high pairing surplus resources number of resource consumption index, by that analogy.
For instance, be 3 if the reference priority level initializing that has adhered to number of users in the resource consumption index is 1, the reference priority level initializing that activated the PDP Context number is 2, distribute the reference priority level initializing of bandwidth.Then behind the Attach Request message that receives user terminal A, RNC-1 can be based on the current monitoring result of distributing bandwidth to each SGSN in the SGSN pond, calculate the current bandwidth left amount of each SGSN in the SGSN pond, the SGSN that the SGSN that the current bandwidth surplus is maximum in the SGSN pond that selection calculates adheres to as user terminal A, by that analogy.
Further, if the reference priority of not default each resource consumption index, then RNC-1 can calculate according to the reference priority of acquiescence, wherein, the reference priority of acquiescence for example can be to have distributed bandwidth the highest, activated the PDP Context several, adhere to number of users and more take second place.
Be understandable that, each RNC of SGSN pond service is based on the monitoring result of current resource consumption index to each SGSN in the SGSN pond, calculate the current resource residual amount of each SGSN in the SGSN pond, all be that each SGSN in the SGSN pond is with respect to the resource residual amount of this RNC, but also can objectively reflect the current load state of each SGSN in the SGSN pond, if each RNC of SGSN pond service all in the manner described above, the resource residual amount of each SGSN in monitoring and the calculating SGSN pond, and the SGSN that adheres to as user terminal of the maximum SGSN of the resource residual amount of selecting it to calculate, also can realize the load balancing of each SGSN in the SGSN pond to a certain extent on the whole.
In actual applications, for the user terminal that each request is adhered to, the SGSN that RNC all can adhere to for its selection in the manner described above, the load balancing of each SGSN in the realization SGSN pond.
Under a kind of application scenarios, if RNC when some moment receive only the Attach Request message of a user terminal, can be this user terminal selecting SGSN according to step 301～304 then; When if RNC receives two or more the Attach Request message of user terminal at synchronization, then RNC can be earlier determines the SGSN of load ratio minimum in the SGSN pond or resource residual amount maximum according to step 301～304, the Attach Request message of these two or more user terminal is sent to the SGSN that this is determined together, after also can be earlier the Attach Request message of one of them user terminal being sent to this SGSN that determines, determine the SGSN of load ratio minimum in the SGSN pond or resource residual amount maximum again according to step 301～304, adhere in the request one of remaining user terminal sends to the SGSN that determines again, if also have the Attach Request message of remaining user terminal, by that analogy according to similar method.
For ease of better understanding the technique scheme of present embodiment, be further detailed below by an instantiation.
For example comprise two SGSN such as SGSN-1 and SGSN-2 in the SGSN pond, wherein, the maximum adhesion number of users of SGSN-1 is 3000, maximum activation PDP activates that the context number is 2400, maximum bandwidth is 2Gbps; The maximum adhesion number of users of SGSN-2 is 5000, maximum activation PDP activates that the context number is 3000, maximum bandwidth is 3Gbps.
Monitoring SGSN-1 that RNC-1 is real-time and SGSN-2 adhere to number of users, activate PDP Context number and distributed resource consumption index such as bandwidth, if when receiving the Attach Request message that user terminal A sends, its SGSN-1 that monitors is current adheres to number of users and is 750, has activated PDP Context several 600 and distributed bandwidth to be current the adhering to number of users and be 1000, activated PDP Context several 600 and distributed bandwidth to be 1.2Gbps of 0.5Gbps, SGSN-2.
RNC-1 calculates the consumption ratio of SGSN-1 and the various resources of SGSN-2 earlier, wherein:
Consumption ratio=the Rs/Rs-max=750/3000=25% that adheres to number of users of SGSN-1;
Consumption ratio=the Rp/Rp-max=600/2400=25% of the activation PDP Context number of SGSN-1;
Consumption ratio=the Rb/Rb-max=0.5/2=25% of the distributed bandwidth of SGSN-1;
Consumption ratio=the Rs/Rs-max=1000/5000=20% that adheres to number of users of SGSN-2;
Consumption ratio=the Rp/Rp-max=600/3000=20% of the activation PDP Context number of SGSN-2;
Consumption ratio=the Rb/Rb-max=1.2/3=40% of the distributed bandwidth of SGSN-2;
For example if the default reference weight of adhering to number of users of RNC-1 is 1, the reference weight that activated the PDP Context number is 2, distribute the reference weight of bandwidth is 3,
Then RNC-1 calculates the load ratio of SGSN-1:
Fb-s1＝25％×1+25％×2+25％×3＝150％
Then RNC-1 calculates the load ratio of SGSN-2:
Fb-s2＝20％×1+20％×2+40％×3＝180％
As seen, the load ratio of the SGSN-1 that calculates is less than the load ratio of SGSN-2, and then RNC-1 is that user terminal A is selected SGSN-1, and sends the Attach Request message of user terminal A to SGSN-1, and SGSN-1 adheres to user terminal A.Alternate manner can be by that analogy.
Therefore, RNC monitors the resource consumption index of each SGSN in the SGSN pond earlier in the present embodiment, when receiving the Attach Request message of user terminal, monitoring result based on current resource consumption index to each SGSN in the SGSN pond, calculate current load ratio or the resource residual amount of each SGSN in the SGSN pond, the SGSN that current SGSN load ratio minimum or that resource residual amount is maximum adhere to as user terminal in the SGSN pond that selection calculates, compared with prior art, help realizing preferably the load balancing of SGSN, promote the overall performance of communication system.
Further, very objective comprehensively of multiple resource consumption index comprehensive reference, load balancing; Can dispose the reference weight of various resource consumption index flexibly or, realize very flexible according to the requirement of keystone resources in the network and operator with reference to priority.
