The embodiment of the present invention provides a kind of load-balancing method, be mainly used for the load balancing of carrying out in each minizone of mobile communication system, the method of the present embodiment is the method for access network equipment such as performed by the equipment such as base station or access point in community, flow chart as shown in Figure 1, comprises following content.

101, obtain the user satisfaction of one or more type services in community, the user satisfaction of the business of current area and neighbor cell can be comprised, particularly, obtain the user satisfaction of non-guaranteed bit rate Non-GBR business in community and/or ensure the user satisfaction of bit rate GBR traffic.

Be appreciated that, the business of subscriber equipment can comprise Non-GBR business and GBR traffic, access network equipment is when obtaining a kind of user satisfaction of type service, can by the subscriber equipment real income service rate of the type business and throughput, be divided by with the restriction speed of the type business or guaranteed rate or history Mean Speed, wherein:

For GBR traffic, need guaranteed rate, the user satisfaction of the GBR traffic that access network equipment obtains can comprise the actual GBR traffic speed of subscriber equipment (GBR subscriber equipment) of GBR traffic and the ratio of the guaranteed rate of this GBR traffic, and be do not need guaranteed rate for Non-GBR business, but need regulation upper limit and AMBR, in this case, the user satisfaction of Non-GBR business that access network equipment obtains can comprise the actual Non-GBR service rate of the subscriber equipment (i.e. Non-GBR subscriber equipment) of Non-GBR business and the restriction speed of this Non-GBR business and the ratio of AMBR, and AMBR is general larger, the Non-GBR service rate of Non-GBR subscriber equipment reality does not reach AMBR, in order to the user satisfaction obtained is more accurate, the history Mean Speed of actual Non-GBR service rate and this Non-GBR business that the user satisfaction of Non-GBR business obtained can comprise the subscriber equipment of Non-GBR business is divided by, here history Mean Speed can be access network equipment before (before the current statistic cycle) the Non-GBR business Mean Speed of Non-GBR subscriber equipment real income of adding up, also can be by the Non-GBR business Mean Speed etc. of one period of long period to the Non-GBR subscriber equipment real income of adding up in same time section.

And the practical business speed of subscriber equipment can be obtained by network equipment short-term or long-term detection, short-term can be the MLB cycle here, can be level or minute rank second, and can be a hour rank for a long time.

Above-mentioned Non-GBR or GBR subscriber equipment refers to the subscriber equipment supporting Non-GBR or GBR traffic, Non-GBR and GBR subscriber equipment can not be same equipment, also can be same equipment, has namely not only supported Non-GBR business but also has supported the equipment of GBR traffic.

102, according to the preset first strategy and 101 user satisfaction obtained, determine the loading condition of community, particularly, the load of Non-GBR business is represented by the user satisfaction of Non-GBR business, or represent the load of GBR traffic by the user satisfaction of GBR traffic, or represent the load of community by the weighted value sum of the user satisfaction of Non-GBR business and the user satisfaction of GBR traffic.Wherein:

The first preset strategy comprises: the load representing respective type business in community by the user satisfaction of arbitrary type service; Or the load etc. of community is represented by the weighted value sum of the user satisfaction of each type service.Wherein can set the user satisfaction higher (or lower) of a certain type service, then in community, the load of the type business is lower, and the weighted value sum obtained is higher, then the load of community is lower.

Particularly, access network equipment, when determining the loading condition of community, can represent the load of Non-GBR business in community, or represent the load of GBR traffic in community by the user satisfaction of GBR traffic by the user satisfaction of Non-GBR business; Or, if 101 acquisitions is the user satisfaction of Non-GBR business and the user satisfaction of GBR traffic, then in 102 by the weighted value sum of the user satisfaction of Non-GBR business and the user satisfaction of GBR traffic, namely the user satisfaction of the user satisfaction of Non-GBR business and GBR traffic obtains the load that value represents community respectively with after the product addition of respective weights value.

103, carry out the equilibrium of cell load, particularly, according to the load of Non-GBR business of expression in 102 or the load of the load of GBR traffic or community, to carrying out cell load equilibrium.

When carrying out cell load balanced, if in current area, the user satisfaction of arbitrary type service is less than (or being greater than) first preset value, or the load value obtained is less than the second preset value, then access network equipment can the flow process of trigger load equilibrium, particularly, using community lower for load in neighbor cell as Target cell.Here the first preset value can be different from the second preset value, and the first preset value and the second preset value do not represent ordinal relation here, but in order to different preset values is described.

Visible, in the load-balancing method of the embodiment of the present invention, by obtaining the user satisfaction of Non-GBR business and/or the user satisfaction of GBR traffic in community, and the load of community is weighed with the user satisfaction obtained, thus carry out the equilibrium of cell load, user satisfaction due to business comprise business actual speed rate, with the restriction speed of this business or the ratio of history Mean Speed or guaranteed rate, like this when weighing the load of community, consider subscriber equipment real income service rate, with restriction speed or the factor such as guaranteed rate or history Mean Speed, only weigh compared with load by the utilance of PRB with prior art, the loading condition that the embodiment of the present invention is determined more can reflect the actual access capability of community, thus save the waste of local resource.

In a specific embodiment, access network equipment, when performing above-mentioned 101, only can be obtained the user satisfaction of GBR traffic, particularly, can be obtained by following step:

A1: the user satisfaction sum of each GBR subscriber equipment and the first ratio S1 of GBR subscriber equipment number in community in calculation plot, or the second ratio S2 of the interior actual GBR traffic speed sum of each GBR subscriber equipment of calculation plot and the GBR traffic guaranteed rate sum of each GBR subscriber equipment.

Be appreciated that, in a community, GBR subscriber equipment has multiple, then when calculating the user satisfaction of GBR traffic, need to consider each GBR subscriber equipment in community, particularly, can the mean value of the user satisfaction of GBR subscriber equipment in calculation plot, that is: S1=(user satisfaction of each GBR subscriber equipment of ∑)/(in community GBR subscriber equipment number), wherein, the user satisfaction of each GBR subscriber equipment is the ratio of the GBR traffic speed of this GBR subscriber equipment real income and the GBR traffic guaranteed rate of this GBR subscriber equipment.

Access network equipment, when calculating the user satisfaction of GBR traffic, can also be calculated by following formula: S2=(each GBR subscriber equipment real income GBR traffic speed of ∑)/(the GBR traffic guaranteed rate of each GBR subscriber equipment of ∑).

B1: using the user satisfaction of the first ratio S1 or the second ratio S2 as GBR traffic in community.

After getting the user satisfaction of GBR traffic, when determining the loading condition of community, the load of GBR traffic only can be represented by the user satisfaction of GBR traffic, can set the community of the user satisfaction larger (or less) of GBR traffic, in Ze Gai community, the load of GBR traffic is lower.

In another specific embodiment, access network equipment, when performing above-mentioned steps 101, only can also be obtained the user satisfaction of Non-GBR business, particularly, can be obtained by following step, flow chart as shown in Figure 2:

A2: the Non-GBR business Mean Speed T of part Non-GBR subscriber equipment in calculation plot _{i_ave}, wherein part Non-GBR subscriber equipment can be the Non-GBR subscriber equipment being in busy state in community.

In the community that access network equipment can be added up short-term (such as MLB cycle), the actual Non-GBR service rate of Non-GBR subscriber equipment calculates, and wherein, short-term can be level or minute rank second, then at calculating Non-GBR business Mean Speed T _{i_ave}time, can directly the actual Non-GBR service rate of the Non-GBR subscriber equipment of busy (idle) state be averaged;

Also the actual Non-GBR service rate of all Non-GBR subscriber equipmenies can be deducted the actual Non-GBR service rate of the Non-GBR subscriber equipment of Idle state and then be averaged, be i.e. T _{i_ave}=(reality total Non-GBR service rate T ' of reality total Non-GBR service rate T1-Idle state Non-GBR subscriber equipment of all Non-GBR subscriber equipmenies)/(all Non-GBR subscriber equipment number N1-Idle state Non-GBR subscriber equipment number N ').In this case, the actual Non-GBR service rate of the Non-GBR subscriber equipment of statistics can sort by access network equipment, and the individual subscriber equipment of N ' selecting actual Non-GBR service rate lower is as the subscriber equipment of Idle state.

B2: the mean value T of Non-GBR business polymerization maximum bit rate AMBR (namely limiting speed) of the Non-GBR subscriber equipment of busy state in calculation plot _{i_sat}, or obtain the history average M of Non-GBR service rate of Non-GBR subscriber equipment of busy state in community _{i_sat}, i.e. the history Mean Speed of Non-GBR business.

Be appreciated that be the upper limit and the AMBR that need regulation service rate for Non-GBR business, then access network equipment is at calculating T _{i_sat}time, can calculate for Non-GBR subscriber equipment in the community of short-term or long-time statistical, then T _{i_sat}=(the Non-GBR business AMBR of ∑ busy state Non-GBR subscriber equipment)/(busy state Non-GBR subscriber equipment number).It is medium-term and long-term can be hour or minute rank.

Due in actual applications, subscriber equipment differs and reaches set upper limit value AMBR surely, and in order to make the user satisfaction that obtains more accurate, access network equipment needs to obtain M _{i_sat}, namely access network equipment carried out the Non-GBR business Mean Speed of the busy state Non-GBR subscriber equipment of long-time statistical before the current statistic cycle, was called history average.It is medium-term and long-term can be 1 hour or a few hours, but time granularity will be enough to distinguish the busy and idle time in every day, such as the different number of days in each week, as the working day of Mon-Fri, and the day off on Sunday Saturday, should add up respectively.

Such as Fig. 3 be access network equipment statistics some day Non-GBR subscriber equipment Non-GBR business Mean Speed, with four hours for statistical unit, can find out, 0 time to 4 time, intra-cell users equipment is relatively more little, then the Non-GBR business Mean Speed of Non-GBR subscriber equipment is higher; Enter the operating time, during as 4-8, intra-cell users number of devices can increase, then the Non-GBR business Mean Speed of Non-GBR subscriber equipment can decline.When statistics can store by access network equipment after adding up, such as can save as history average table as shown in Figure 3, represent at history average and comprise statistical time range, and in the Non-GBR business Mean Speed that each statistical time range correspondence is added up.

And the access network equipment of each community can in units of week, to Monday weekly to Sunday, the Non-GBR business Mean Speed of Non-GBR subscriber equipment is added up respectively, and stores 7 mean value tables.But due to the working day (or the day off on Saturday and Sunday) of Mon-Fri, in corresponding statistical time range, the characteristic of Non-GBR business Mean Speed can be relatively, in order to reduce memory space, access network equipment only can store two mean value tables, respectively for working day and day off.

Access network equipment can constantly upgrade these history average tables according to the data of current statistic period statistics and the local data stored, particularly, access network equipment can by the history value b of the Non-GBR business Mean Speed of the Non-GBR subscriber equipment of community within the current statistic period of storage and the product of the first weighted value λ, in the community added up with the current statistic period, the Non-GBR business Mean Speed c of Non-GBR subscriber equipment and the product addition of the second weighted value (1-λ) obtain updated value d, i.e. d=λ * b+ (1-λ) * c, wherein the first weighted value and the second weighted value sum are 1, if λ is less, then illustrate that the history value of consideration is fewer,

Access network equipment, can using the history average M of this updated value as the Non-GBR service rate of Non-GBR subscriber equipment in community after obtaining updated value d _{i_sat}, and the history value b of the Non-GBR business Mean Speed of the Non-GBR subscriber equipment of the community of storage can be updated to updated value d.

Such as, when if the current statistic period is 4 of Sunday to 8 time, then access network equipment can by this locality store day off history average table in 4 time to 8 time Non-GBR business Mean Speed be multiplied with (1-λ) after, obtain updated value with the Non-GBR business Mean Speed of the current actual count of access network equipment and the product addition of λ.

C2: the Non-GBR business Mean Speed T that A2 is calculated _{i_ave}the mean value T of the Non-GBR business AMBR calculated with B2 _{i_sat}ratio as the user satisfaction of Non-GBR business, or the history average M that the Non-GBR business Mean Speed calculated by A2 and B2 obtain _{i_sat}ratio as the user satisfaction of Non-GBR business.

It should be noted that, the user satisfaction of the Non-GBR business of the Non-GBR subscriber equipment (i.e. part Non-GBR subscriber equipment) based on busy state can be got by above-mentioned A2 to C2, and above-mentioned A2 and B2 does not have absolute ordinal relation, can perform simultaneously, also can sequentially perform, the just concrete situation shown in Fig. 2.In other specific embodiment, access network equipment also can obtain the user satisfaction of the Non-GBR business based on Non-GBR subscriber equipment whole in community, concrete grammar and above-mentioned steps A2 to C2 similar, difference is, when calculating the Mean Speed of Non-GBR business, in calculation plot, the actual speed rate of the Non-GBR business of all Non-GBR subscriber equipmenies is average, and when calculating the mean value of AMBR AMBR average of the Non-GBR business of calculation plot all Non-GBR subscriber equipment, the history average of Non-GBR service rate of all Non-GBR subscriber equipmenies in calculation plot when calculating history average.

After the user satisfaction obtaining Non-GBR business, when determining the loading condition of community, the load of Non-GBR business only can be represented by the user satisfaction of Non-GBR business, can set the community of the user satisfaction larger (or less) of Non-GBR business, in Ze Gai community, the load of Non-GBR business is lower.

In other specific embodiment, access network equipment, when performing above-mentioned steps 101, only can be obtained the user satisfaction of Non-GBR business, particularly, can be obtained by following mode:

The ratio of Non-GBR subscriber equipment (or part Non-GBR subscriber equipment) number in the user satisfaction sum of each non-guaranteed bit rate Non-GBR subscriber equipment (or part Non-GBR subscriber equipment) and community in calculation plot, as the user satisfaction of Non-GBR business in community.Wherein, the user satisfaction of each Non-GBR subscriber equipment is the actual Non-GBR service rate of this Non-GBR subscriber equipment, limits the ratio of the history Mean Speed of speed and AMBR or Non-GBR business with the Non-GBR business of this Non-GBR subscriber equipment; And part Non-GBR subscriber equipment can be the Non-GBR subscriber equipment being in busy state.

Shown in figure 4, the load-balancing method of the embodiment of the present invention is described with a specific embodiment below, specifically comprises following content.

201, access network equipment carries out scheduling of resource to subscriber equipment, and subscriber equipment then runs business according to the resource of access network equipment scheduling.

Access network equipment is when carrying out scheduling of resource, can according to the principle of g* equity dispatching+(1-g) * maximum throughput, the subscriber equipment of community is dispatched, if with g for 0.5, then with equal weight, access network equipment can consider that equity dispatching and maximum throughput are to carry out scheduling of resource simultaneously, specifically will 1/2 of total resources for equity dispatching, other 1/2 for the scheduling of maximum throughput.

202, the utilance of PRB in access network equipment statistics current area, if determine that in current area, the utilance of PRB is less than 100%, then perform 203, if determine that in current area, the utilance of PRB equals 100%, then perform 204.

203, access network equipment determines the loading condition of current area according to the utilance of PRB, if high capacity, the then flow process of trigger load equilibrium, particularly, select the utilance of PRB in the utilance of PRB in neighbor cell and current area to have the community of certain difference (preset difference) as Target cell, certain customers' equipment of current area is switched to Target cell.

204, access network equipment obtains the user satisfaction of one or more type services in community, and determines the loading condition of community according to the user satisfaction obtained, and comprises the loading condition of neighbor cell and current area.Specifically when determining the loading condition of community, as described in Fig. 1 correspondence embodiment, can not repeat at this.

Access network equipment can obtain the user satisfaction of GBR traffic by above-mentioned A1 to B1, and the user satisfaction that can set GBR traffic is larger, then the load of community is lower; Access network equipment can also obtain the user satisfaction of Non-GBR business by above-mentioned A2 to C2, and the user satisfaction that can set Non-GBR business is larger, then the load of community is lower; Access network equipment can also get the user satisfaction of GBR traffic and the user satisfaction M1 of Non-GBR business and M2 respectively, and by M1 and M2 respectively with the product addition of respective weights value after the load value Load that obtains, such as, Load=k*M1+M2, here because GBR traffic has higher priority, k can be more than or equal to 1, and can set the load value Load value obtained larger, then the load of community is lower.

205, access network equipment carries out the process of load balancing according to the loading condition determined.

When carrying out load balancing, access network equipment can first select PRB utilance in neighbor cell to be less than the community of 1 as Target cell, if there is not the community that PRB utilance is less than 1, then access network equipment can be selected in neighbor cell, in the user satisfaction of Non-GBR business or the user satisfaction of GBR traffic and current area, the user satisfaction of Non-GBR business or the user satisfaction of GBR traffic have the community of certain difference (preset difference) as Target cell, and the subscriber equipment of part Non-GBR business in current area or the subscriber equipment of GBR traffic are switched to Target cell, or,

Access network equipment can select the weighted value sum of user satisfaction in neighbor cell and the weighted value sum of current area user satisfaction to have the community of certain difference as Target cell, and part subscriber equipment in current area is switched to Target cell, wherein the weighted value sum of user satisfaction is the weighted value sum of the user satisfaction of Non-GBR business and the user satisfaction of GBR traffic in community here.

It should be noted that, in the load balancing process of reality, the PRB utilance considering community can not be needed, and directly determine the loading condition of community according to the corresponding embodiment of Fig. 1, and carry out load balancing.

In the process of above-mentioned load balancing, mutually can send resource status updating message (RESOURCESTATUSUPDATE) between two reciprocity access network equipments (equipment that namely function is identical with network site), and increase new cell in resource status updating message; Need when communicating between the access network equipment of some equity through core net, then at this moment transmission response container (SONTransferResponseContainer) message can be transmitted to the access network equipment of another equity by access network equipment by core net, and increases new cell in transmission response container message.

In resource status updating message, or the information such as the user satisfaction of Non-GBR business or the user satisfaction of GBR traffic can be carried in the new cell of transmission response container message increase; Or carry the actual speed rate of Non-GBR business in new cell, and the information such as the restriction speed of Non-GBR business or history Mean Speed;

Or in new cell, carry the actual Non-GBR service rate of non-guaranteed bit rate Non-GBR subscriber equipment in community, Non-GBR subscriber equipment number, with the mean value of Non-GBR business polymerization maximum bit rate AMBR of Non-GBR subscriber equipment in community or the history average of the Non-GBR service rate of Non-GBR subscriber equipment, calculate the user satisfaction of Non-GBR business to make another access network equipment according to the method for above-mentioned A2 to C2; Or in new cell, carry the user satisfaction sum of Non-GBR subscriber equipment in current area, with Non-GBR subscriber equipment number, to make another access network equipment this user satisfaction sum and subscriber equipment number be divided by and obtain the user satisfaction of Non-GBR business;

Or in new cell, carry in current area the user satisfaction sum ensureing bit rate GBR subscriber equipment, with GBR subscriber equipment number, calculate the user satisfaction of GBR traffic to make another access network equipment according to the method for above-mentioned A1 to B1; Or in new cell, carry the actual speed rate of GBR traffic and the guaranteed rate of GBR traffic in current area, calculate the user satisfaction of GBR traffic to make another access network equipment according to the method for above-mentioned A1 to B1.The information of community, place can be sent to another access network equipment 2 by such access network equipment 1, facilitates another access network equipment 2 to determine the loading condition of community, access network equipment 1 place, thus carries out load balancing.

Wherein two of transmission resource state updating message or transmission response container message reciprocity access network equipments can be the equipment of homologous ray, also can be the equipment of different system.Such as: in Long Term Evolution (LongTermEvolution, LTE) system, standard interface X2 directly can be passed through in two base stations, mutually above-mentioned resource status updating message is sent; Also can be communicated by core net, particularly, a base station in LTE system sends above-mentioned transmission response container message to core net such as mobile management entity (MobilityManagementEntity by standard interface S1, MME), then by core net this transmission response container message sent to another base station in LTE system.

Again such as, base station in LTE system can be communicated with the access network equipment of other network system by core net, wherein other system can be global system for mobile communications (GlobalSystemofMobilecommunication, GSM), broadband CDMA system (WidebandCodeDivisionMultipleAccess, or the system such as code division multiple access (cdma) 2000 system WCDMA), particularly: a base station in LTE system sends above-mentioned transmission response container message to core net by standard interface S1, by the interface with other system, this transmission response container message is passed to the interdependent node of other system again by core net, by radio network information management process (RANInformationManagement, RIM) realize.

The embodiment of the present invention also provides a kind of load-balancing method, be mainly used for the load balancing of carrying out in each minizone of mobile communication system, the method of the present embodiment is the method performed by access network equipment such as base station or access point etc. in community, flow chart as shown in Figure 5, comprises following content.
