Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Along with the fast development of RAT, when traditional RAT network also when infrastructure service is provided, new RAT network has needed to come into operation.In order to utilize existing network resources better, different wireless access technology (inter-RAT) systemic-function has precedence over same wireless access technology (intra-RAT) systemic-function and implements in network.
For example, the residential quarter of 2G or 3G standard, global system for mobile communications (Global System of Mobile communication for example, GSM) or universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS) etc., provide the basis of whole network area to cover, new RAT system, Long Term Evolution (Long Term Evolution for example, LTE) system, Long Term Evolution is senior, and (long term evolution advanced, LTE-A) system etc. provide the focus increase-volume (capacity enhancement) in the same area.Be in (the Low Load Period of low duty cycle with statistical regularity when the RAT residential quarter of focus increase-volume, LLP) time, Active UE under the low load condition in the RAT residential quarter is directionally switched among the 2G or 3G standard residential quarter that the basis covering is provided, and energy-conservation closing carried out in the RAT residential quarter.
Yet, more than different system cell is energy-conservation faces following problem: when needs are carried out energy-conservation closing to certain residential quarter, there is Active UE in this residential quarter, this Active UE institute loaded service has only the RAT system under this residential quarter just to have the ability to provide, if energy-conservation closing carried out in this residential quarter, then (Quality of Service's service quality of this Active UE QoS) will be affected.For example:
Situation one: Active UE is for supporting the multimode terminal of multiple RAT standard, and it has carried to have only and desires to carry out the business that corresponding data rate is just had the ability to provide in the energy-conservation residential quarter of closing.For example, when UE in the GSM/UMTS combination networking initiated or carries out the 384kbps Packet Service, this service bearer can only be provided by the UMTS network.UE initiates or when carrying out the video traffic of 10Mbps, this business can only be provided by the LTE network in the UMTS/LTE combination networking.
Situation two: Active UE is the single-mode terminal of a kind of RAT standard of support, and desires to carry out the residential quarter that the energy-conservation residential quarter of closing is its RAT standard of supporting.For example, the LTE data card of single mode.
More than two kinds of situations, unaffected for the QoS of survice that guarantees Active UE, at this moment, energy-conservation closing can not be carried out in the residential quarter.
In addition, different system cell Energy Saving Strategy also faces the problem of free time (Idle) UE gravity treatment more than.When a large amount of Idle UE resides in certain residential quarter, close and this residential quarter is instantaneous, numerous Idle UE carries out different system cell gravity treatment and the renewal of occurrence positions district, to wireless access network (Radio Access Network, RAN) and core net (Core Network CN) forms in short-term signaling storm.At this moment, energy-conservation closing can not be carried out in the residential quarter.
For this reason, following examples provide the management method of different system cell, in different system cell scene, in the certain energy-conservation gain of maintenance, have guaranteed that different kinds of business QoS is unaffected in energy-conservation process.
For convenience of description, the residential quarter to two class different role under the different energy saving of system scene defines:
The first wireless access technology RAT, 1 residential quarter: the residential quarter that provides the basis of the same area to cover for the residential quarter that can carry out Energy Saving Strategy, for example: the 2G in the above-mentioned scene or 3G residential quarter.
The second wireless access technology RAT, 2 residential quarters: can carry out the residential quarter of Energy Saving Strategy, for example: the LTE residential quarter in the above-mentioned scene.
Please refer to Fig. 1, the exemplary flow chart of the management method of a kind of different system cell that it provides for the embodiment of the invention.As shown in Figure 1, this method comprises:
S110: access network equipment switches to the first wireless access technology RAT, 1 residential quarter with the active user device of not carrying specific transactions in the second wireless access technology RAT, 2 residential quarters, and wherein said specific transactions is that described RAT 2 residential quarters have the business that bearing capacity and described RAT 1 residential quarter do not have bearing capacity;
S120: described access network equipment is controlled described RAT 2 residential quarters and is entered the restriction energy saver mode, thereby, RAT 2 residential quarters are activated to limiting energy saver mode.
In the face of in RAT 2 residential quarters during always present a small amount of specific transactions, above method provides a kind of restriction Energy Saving Strategy: the active user device that will not carry specific transactions switches to RAT 1 residential quarter, and this is in order to satisfy the energy-conservation application demand of inter-RAT (being different from the energy-conservation key property of intra-RAT).And, be different from prior art RAT 2 residential quarters are closed fully, but RAT 2 residential quarters are activated to limiting energy saver mode, namely the closed portion resource is supported the operation of RAT 2 specific transactions under this state with RAT 2 system resources of minimum.Thereby, in the certain energy-conservation gain of maintenance, guaranteed that different kinds of business QoS is unaffected in energy-conservation process.
For the implication that makes above specific transactions easy to understand more, below the different service types under the different system cell environment is classified, in optimal wireless access system, carry respectively and be described so that be under the situation of low load dissimilar business in RAT 2 residential quarters, be UMTS with RAT 1 simultaneously, RAT 2 is that LTE is example, and the strategy of the service distributing that some are common (traffic steering) is listed in the table 1.
Table 1
At evolved packet system (Enhanced Packet System, EPS) in, QoS classification logotype symbol (QoS Class Identifier, QCI) be a quantity grade, be used for representing to control the access point parameters of other data packet transmission processing of carrying level, for example dispatch weight, insert thresholding, queue management thresholding, link layer protocol configuration etc., and represented EPS each business data flow (Service Data Flow, the QoS characteristic that SDF) provides should be provided.The service bearer of different Q CI can be divided into two classes:
RAT 2 specific transactions: refer to that this bearing capacity for example can refer to enough QoS abilities for RAT 2 residential quarters have the business that bearing capacity and RAT 1 residential quarter do not have bearing capacity.Following two kinds of business for example: the first, if should business be provided by RAT 1 residential quarter, QoS will demote; The bandwidth ability of the second, RAT, 1 residential quarter can't satisfy the service rate requirement of this specific transactions at all.For example: the real-time game business (QCI=1) in the table 1, interactive packet video business (QCI=3), all belong to RAT 2 specific transactions, these business have higher service rate requirement, need the RAT system that the bearing capacity of successive bits speed is provided.
RAT 2 and RAT 1 general service: refer to that RAT 1 residential quarter or RAT 2 residential quarters can provide the business of identical QoS ability, the experience to business does not have marked difference to subscriber equipment in RAT 1 residential quarter and RAT 2 residential quarters.For example: the VOIP business (QCI=2) in the table 1, TCP interactive service (QCI=7) all belongs to RAT 1 and RAT 2 general services, and these business are less demanding to service rate, even provide service bearer by the RAT1 residential quarter, QoS also can be guaranteed.Such business is also referred to as the business of sending out in wink in short-term (Bursty Traffic).
As seen, specific transactions can determine according to quality of service class identifier QCI, and QCI is a kind of quantity grade, determines that by QCI specific transactions realizes simply, and has thinner granularity.Yet the embodiment of the invention is not limited thereto, and can also utilize other any suitable dimensions to distinguish, for example subscriber's framework identifier (Subscriber Profile ID, SPID), service delay, service rate etc.
In addition, for the implication that makes above restriction energy saver mode easy to understand more, be described limiting energy saver mode below:
Limiting energy saver mode is that the energy saver mode under the load condition is hanged down in the residential quarter, is limiting under the energy saver mode, can only provide professional to the bimodulus UE of carrying RAT 2 specific transactions and/or the RAT 2UE of single mode.Before the RAT2 residential quarter enters this restriction energy saver mode, with RAT 2 and RAT 1 general service load bearing migration to RAT 1 residential quarter, by the capacity utilance of service distributing (traffic steering) optimization RAT 1 residential quarter, support the operation of RAT 2 specific transactions under this pattern with RAT 2 system resources of minimum.
Table 2 has been concluded the outside visible characteristic of restriction energy saver mode:
Table 2
As seen, limiting under the energy saver mode: RAT 2 and RAT 1 residential quarter all are in low load condition; The RAT2 specific transactions, as: conversation Switch Video business, stream is professional, is retained in RAT 2 residential quarters; RAT2 and RAT 1 general service, as: VOIP business, TCP interactive service switch to RAT 1 residential quarter; The RAT 2UE of single mode remains on RAT 2 residential quarters under the energy-conservation attitude that is in restriction.Idle UE still is distributed in RAT 2 or RAT 1 residential quarter constant separately, does not need to do directed residential quarter gravity treatment.
According to the embodiment of the invention, switch to the RAT1 residential quarter by the active user device that will not carry specific transactions, in RAT 2 residential quarters, only keep the subscriber equipment that carries specific transactions, and described RAT 2 residential quarters activated to limiting energy saver mode, can be achieved as follows effect:
A) the operation demand of the service bearer (single mode situation) of RAT 2 specific transactions carryings (multimode situation) and/or single mode RAT 2UE is satisfied in RAT 2 residential quarters with the system resource of minimal amount;
B) dissimilar business are under RAT 2 residential quarters " restriction energy saver mode ", and QoS does not demote, energy-saving effect more has gain than " the non-energy saver mode of opening fully ";
C) because RAT 1 residential quarter also is in low load condition, switches to RAT 1 residential quarter so RAT 2 and the carrying of RAT 1 general service are directed, thereby can improve the capacity utilance of RAT 1 residential quarter;
D) RAT 2 residential quarters are limiting the operation that has stably guaranteed RAT 2 specific transactions under the energy saver mode, effectively avoided the ping-pong in the low duty cycle in RAT 2 residential quarters, described soldier pang effect refers to, because there not being active user to allow RAT 2 residential quarters enter the energy saver mode of contract fully, after this RAT 2 residential quarter short-term burst RAT, 2 specific transactions requests and temporarily being opened, after service ending in short-term, RAT 2 residential quarters enter the energy saver mode of contract fully again; And
E) free subscriber still is distributed in RAT 2/RAT 1 residential quarter constant separately, do not need to do directed residential quarter gravity treatment, avoided potential and initiated lane place or tracing section updating process simultaneously because of a large amount of free subscribers wireless access network and core net are produced in short-term signaling storm.
Can know that in above description process limiting energy saver mode is that the energy saver mode under the load condition is hanged down in RAT 2 residential quarters, be not RAT 2 residential quarters can be activated to limiting energy saver mode in any case.Therefore provided restriction energy saver mode activation condition below.For example, when low duty cycle of RAT 2 residential quarters then, illustrate that RAT 2 residential quarters are under the low load condition of measurement period.At this moment, RAT 2 residential quarters can be activated to limiting energy saver mode, corresponding, limit low duty cycle that the energy saver mode activation condition comprises RAT 2 residential quarters then.
Wherein, low duty cycle (Low Load Period, LLP) be by network management device according to the performance measurement data of phase of history measurement period collection form with sky, week, month be the time cycle fixing, that repeat to take place of unit, described RAT 2 cell loads in the described time cycle (be that LTE be example with RAT 2, cell load refers to the occupancy of residential quarter Physical Resource Block) are lower than a default load-threshold all the time.For example, according to 24 hours every days (00:00:00-23:59:59) as a cell load statistical measurement cycle, divide the low duty cycle (being the non-peak value period) of base station or residential quarter, by network management device, for example, Operations, Administration and Maintenance (Operation, Administration and Maintenance, OAM) system, historical load statistics data and inner load-threshold according to base station or residential quarter are differentiated, and form the initial and concluding time of low duty cycle of residential quarter or zero-time and the lasting duration of low duty cycle.
Judge whether satisfy can at access network equipment place realize, also can realize at the network management device place if limiting the energy saver mode activation condition, be described below respectively:
Realize at the access network equipment place: because the load condition of the monitor cell that access network equipment can be real-time, so can expand limiting the energy saver mode activation condition at the access network equipment place, make RAT 2 residential quarters being conducive to more to enter under the situation that limits energy saver mode, just enable the restriction energy saver mode.For example, can obtain the load of RAT 1 residential quarter and RAT 2 residential quarters in real time, thereby under the condition of the low duty cycle of adding up, judge further whether its actual load state is fit to enable the restriction energy saver mode.For another example, consider the loaded state of specific transactions, can judge further that the situation of its actual bearer number (perhaps does statistics as the low duty cycle of above RAT 2 residential quarters to its actual bearer number, obtain the low carrying cycle of specific transactions, this more is applicable to the process of realize judging at the network management device place that below will describe, comprises that residential quarter E-RAB according to the corresponding QCI of specific transactions counts the performance statistics item or carries out the specific transactions calculating in low carrying cycle according to the cumulative effects that the residential quarter Physical Resource Block occupancy of the corresponding QCI of specific transactions is counted the performance statistics item) whether be fit to enable the restriction energy saver mode.Therefore, limit the energy saver mode activation condition and can comprise one or more in the following condition, wherein the carrying number of specific transactions can be implemented as the current E-RAB number of the corresponding QCI of specific transactions or the occupancy of current physical piece:
The first, the low duty cycle of RAT 2 residential quarters then;
The second, the first load-threshold Th_act1 is less than or equal in the present load of RAT 2 residential quarters;
Three, the second load-threshold Th_act2 is less than or equal in the present load of RAT 1 residential quarter;
Four, the specific transactions of RAT 2 residential quarters carrying number is less than or equal to carrying number thresholding Th_act3.
Realize at the network management device place: if the network management device load condition of monitor cell in real time will need great resource overhead.Therefore, in practical application at present, the performance measurement data of utilizing access network equipment to report is added up and is obtained low duty cycle or low carrying cycle of specific transactions more, and the statistical in low carrying cycle of specific transactions is similar with the description of above low duty cycle, does not repeat them here.At this moment, limit the energy saver mode activation condition and can comprise one or more in the following condition:
The first, the low duty cycle of RAT 2 residential quarters then;
The second, the low carrying cycle of the specific transactions of RAT 2 residential quarters then.
In addition, how many available resources load refers to have in the residential quarter distribute to the service request of UE at the residential quarter, and cell load is more big, and available resources are more few; Correspondingly, carrying is at UE, and when UE initiated service request, network will distribute a carrying, the i.e. bearer resource of business for it, and a UE can have a plurality of carryings simultaneously, moves different business respectively.And the carrying number of above specific transactions and the load of residential quarter can obtain by the performance measurement data of network, and above each thresholding Th_act1, Th_act2, Th_act3 can be arranged according to cell configuration or service traffics etc. by operator, and the embodiment of the invention is not done any restriction.For example, in the LTE system, per E-UTRAN Radio Access Bearer that can obtain the residential quarter in 15 minutes (EUTRAN Radio Access Bearer, E-RAB) number, per hour can obtain Physical Resource Block (Physical Resource Block, the PRB) occupancy of residential quarter.Therefore, above load-threshold and carrying number thresholding can arrange according to PRB occupancy and E-RAB number.Yet not as limit, art technology person can arrange in different RAT systems as required accordingly in the embodiment of the invention, and it is well known to those skilled in the art and does not repeat them here.Yet, in a preferred embodiment, more than each thresholding Th_act1, arranging of Th_act2, Th_act3 can do different settings according to QCI, thereby make up the thresholding that different activation limits energy saver mode at different business.
In addition, RAT 2 residential quarters are activated to after the restriction energy saver mode, can also be comprised the deactivation process that limits energy saver mode.Certainly, just be in RAT 2 residential quarters that limit under the energy saver mode for this, when no longer satisfying the energy saver mode service conditions of hanging down under the load condition, also comprise the deactivation process to the restriction energy saver mode of RAT 2 residential quarters.
Corresponding to above restriction energy saver mode activation condition, provide herein and limit energy saver mode deexcitation condition, comprise that the low duty cycle of RAT 2 residential quarters is out-of-date.Accordingly, when satisfying restriction energy saver mode deexcitation condition, RAT can withdraw from the restriction energy saver mode in 2 residential quarters.
With the judgement of above restriction energy saver mode activation condition, the judgement that limits energy saver mode deexcitation condition can realize at the access network equipment place, also can realize at the network management device place.Be described below respectively:
Realize at the access network equipment place: with the expansion reason of above restriction energy saver mode activation condition, limit energy saver mode deexcitation condition and can comprise one or more in the following condition:
The first, the low duty cycle of RAT 2 residential quarters is out-of-date;
The second, the load of RAT 1 residential quarter is higher than load-threshold Th_deact1;
Three, the specific transactions of RAT 2 residential quarters carrying number is higher than carrying number thresholding Th_deact2.
Load-threshold Th_deact1 and load-threshold Th_act2 can be identical, also can be different, and the embodiment of the invention is not done any restriction.Carrying number thresholding Th_deact2 and carrying number thresholding Th_act3 can be identical, also can be different, and the embodiment of the invention is not also done any restriction.At this moment, whether the load condition that can no longer consider RAT 2 residential quarters satisfies threshold requirement.
Realize at the network management device place: with the expansion reason of above restriction energy saver mode activation condition, limit energy saver mode deexcitation condition and can comprise one or more in the following condition:
The first, the low duty cycle of RAT 2 residential quarters is out-of-date;
The second, the low carrying cycle of the specific transactions of RAT 2 residential quarters is out-of-date.
Can know from above description, the judgement that limits energy saver mode activation condition and deexcitation condition can be carried out at access network equipment, also can carry out at network management device, if carry out at network management device, need access network equipment that the performance measurement data of the network of acquisition is reported network management device, carry out above judgement by network management device according to the data that report, and according to judged result, send activation or deexcitation and instruct to access network equipment.Wherein, described activation instruction is used to indicate access network equipment the active user device of not carrying specific transactions in RAT 2 residential quarters is switched to RAT 1 residential quarter, and control RAT 2 residential quarters enter the restriction energy saver mode; The deexcitation instruction is used to indicate access network equipment control RAT 2 residential quarters and withdraws from the restriction energy saver mode.
The application of management method in distributed network architecture and centralized network architecture of different system cell is described below.And in distributed network architecture, the judgement of restriction energy saver mode activation condition described above or deexcitation condition is carried out at access network equipment; In centralized network architecture, the judgement of restriction energy saver mode activation condition described above or deexcitation condition is carried out at network management device.
Please refer to Fig. 2 and Fig. 3, its entering of management method of different system cell under distributed network architecture that illustrates respectively according to the embodiment of the invention limits energy saver mode and withdraws from the exemplary signal flow graph that limits energy saver mode.This distributed network architecture comprises network manager 210, RAT 2 NE Explorer 220, RAT 2 network elements 230, RAT 1 network element 240 and RAT 1 NE Explorer 250.Under this distributed network architecture, can directly communicate between RAT 1 network element and RAT 2 network elements or carry out information interaction by its superior node (for example network manager 210), more than the judgement that limits energy saver mode activation condition or deexcitation condition can be carried out at access network equipment, for example can be at RAT 2 network elements 230 and/or RAT 1 network element 240 (for example, base station, evolved base station etc.), RAT 2 NE Explorer 220.Network manager 210 configurations limit the energy saver mode strategy, and this strategy is specifically carried out by RAT 2 network elements 230.
As shown in Figure 2, under distributed network architecture, comprise the steps: about the management method that limits the different system cell that energy saver mode activates
Whether then 21:RAT 2 network elements 230 judge the low duty cycle of RAT 2 residential quarters.
22:RAT 2 network elements 230 judge whether the load of RAT 2 residential quarters and specific transactions carrying satisfy condition, i.e. whether load is less than or equal to the first load-threshold Th_act1, and whether specific transactions carrying number is less than or equal to carrying number thresholding Th_act3.
23:RAT 2 network elements 230 obtain the load information of RAT 1 residential quarter by RAT 1 network element 240.This step 23 can be carried out after step 22, also can carry out before step 21.That is, can carry out after the home cell judgement by RAT 2 access network equipments, when needing this load information, go again to call; Can just call in beginning, so that follow-up use, the embodiment of the invention is not done any restriction yet.
24:RAT 2 network elements 230 judge whether the load of RAT 1 residential quarter satisfies condition, i.e. whether load is less than or equal to the second load-threshold Th_act2.
Above step 23 and 24 can replace with: RAT 1 network element 240 judges whether the load of RAT 1 residential quarter satisfies condition, i.e. whether load is less than or equal to the second load-threshold Th_act2.If satisfy condition, then send signaling RAT 2 network elements 230 its judged results.Then RAT 2 network elements carry out following operation according to its judged result.
25: when above judged result is when being, RAT 2 network elements 230 switch to RAT 1 residential quarter with the active user device of not carrying specific transactions in RAT 2 residential quarters, and control RAT 2 residential quarters enter the restriction energy saver mode.
After execution of step 25, change has taken place in the state of RAT 2 residential quarters, for the ease of the management of network manager 210, this state can be changed informing network manager 210 (steps 26), simultaneously, also this state can be changed notice RAT 1 network element 240 (step 27).
Please continue with reference to figure 3, the difference of itself and embodiment shown in Figure 2 is that present embodiment is the management method about the different system cell that limits the energy saver mode deexcitation.Embodiment illustrated in fig. 3 is that the situation that limits energy saver mode is withdrawed from RAT 2 residential quarters having satisfied the wherein load of RAT 1 residential quarter to be higher than load-threshold Th_deact1.Comprise the steps:
