Existing isomery cellular network increases network capacity by introducing low power nodes, its essence is the focus area first determining that business is occurred frequently, then multiple SmallCell is disposed in this area, increasing Radio Resource (PRB) quantity available in network by improving number of nodes, improving localized network capacity to meet business demand.Common deployment way is, in the macrocellular quorum sensing inhibitor better very large region (i.e. hot zones hotspot) of service request amount, the SmallCell of deployment some meets this hot zones business demand.Increase some areas throughput by disposing multiple SmallCell, and then increase the entire system capacity of macrocellular covering area.
Because SmallCell base station transmitting power is lower than macro base station, and the macro base station RSS quality of deployed position may be better, if still adopt the switch decision criterion that A3 event triggers, then Macro/Small cross-layer handoff boundary can distance SmallCell base station excessively near, cause only having small part extreme just can be linked into SmallCell close to the user of little base station and served by it.For improving the utilization rate of SmallCell, the decision rule of A2/A4 joint handoff is proposed in 3GPPTR36.842, when the RSS of MacroCell lower than certain thresholding and the RSS of SmallCell higher than certain thresholding time, namely UE is switched to SmallCell.The method can guarantee that the UE within the scope of hotspot all accesses SmallCell, makes full use of SmallCell resource.
In some actual scenes, user's total amount is certain.According to above-mentioned isomery cellular deployment mode, when a large number of services concentrate occur in hot zones time, non-hot zones customer service is little, and macro base station Radio Resource there will be certain free time.Along with passage of time, may there is change in section business hotspot at some time, and a considerable amount of user shifts out Hotspot region, and macro base station resource is utilized again.For school, dispose MacroCell+SmallCell isomery cellular network in campus after, in the period of attending class a large amount of integrated distribution of customer service in teaching region carry by SmallCell, and outside this region, user is little, and macro base station resource occurs idle; In time at school outside the period, customer service can be distributed in whole campus area relative distribution, and macro base station resource is utilized.If macro base station idling-resource can be used when service set is distributed in hotspot, network capacity can be promoted further.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of isomery cellular network based on service-aware station between frequency spectrum resource polymerization, in the method, SON entity is according to the business state information obtained from base station with from the service distribution situation the UE positional information perception current network that evolved Serving Mobile Location Center E-SMLC obtains, when service set is distributed in hotspot (this region and cellulor overlay area), outside hotspot, service distribution is little, for UE disposes frequency spectrum resource aggretion type dual link between website, on MacroCell and SmallCell, carry out transfer of data with hoist capacity simultaneously, if the non-integrated distribution of business, then not adopt between website aggregation of resources to reduce relevant control signaling consumption.
For achieving the above object, the invention provides following technical scheme:
Isomery cellular network based on service-aware station between a frequency spectrum resource polymerization, comprise the following steps:
1) the SON entity in isomery honeycomb scene adds service distribution analytic statistics module, according to the UE positional information got from E-SMLC and the business state information got from macro base station, analysis draws accurate service distribution information data, and the number of services understood in SmallCell overlay area accounts for the total number of services ratio of network;
2) macro base station is according to the service distribution situation got, and judges dispersion or the collected state of business in network, then carries out P-Cell/S-cell configuration to MacroCell and the SmallCell in isomery cellular network;
3) if service set is distributed in SmallCell overlay area, then according to UE type in network, judge the carrier aggregation (CAT6) after the whether compatible Release9 of UE in isomery cellular network, and start the auxiliary carrier transceiver of eligible UE; If business dispersion distribution, this deterministic process does not perform, and all UE all do not adopt carrier aggregation, selects concrete access community according to alien frequencies switching criterion;
4) under service set is distributed in the prerequisite of SmallCell overlay area, according to step 3) judged result, to CAT6 and above UE, dispose InternodesResourceAggregation type dual link, polymerization PCell, SCell two-tier network resource, promotes isomery cellular network population size;
5) to below CAT6 UE, only monitor the carrier wave of P-Cell and be assigned with resource thereon, not performing S-CellAddition operation.
Further, in step 1) in, SON entity obtains the geographical location information of user when business is carried out from E-SMLC, obtains business state information from base station side RRC protocol stack, draws comparatively accurate business location distribution situation after analysis; This distribution situation is issued to the macro base station in isomery cellular network by S1 interface, makes this macro base station know the distribution situation of business near it, and this distribution situation is as follow-up foundation of carrying out network optimization configuration.
Further, in step 2) in, if macro base station learns that the customer service majority (ratio can be arranged) under its covering concentrates on SmallCell overlay area, then network configuration macro base station is P-Cell, and configuration SmallCell is S-Cell.P-Cell issues RRC chain of command transfer instruction by Xn interface to S-Cell, namely retains the data surface of S-Cell, and the original radio bearer connection control of S-CellRRC layer is all transferred P-Cell to and controlled; New control signal is produced by P-Cell, both directly can be sent to UE by P-Cell, also first by P-Cell, signaling can be forwarded to S-Cell by the backhual between P, S-Cell, then sends signaling to UE by S-Cell.
Further, in step 3) in, when service set be distributed in SmallCell overlay area cause P-Cell resource to occur to a certain degree idle time, UE can make full use of idling-resource by polymerization P-Cell and S-Cell frequency spectrum resource, promotes network throughput; Now be necessary to judge whether UE type possesses carrier aggregation function, and send carrier aggregation function on signaling by base station to more than CAT6 user, UE starts to monitor and measures auxiliary carrier wave SCC; If business does not concentrate on SmallCell overlay area, then this process is without the need to performing, no matter which kind of UE all maintains different-frequency measure configuration, performs alien frequencies and switch between macro base station and SmallCell, only need monitor a kind of carrier wave thus reduce UE and hold energy consumption.
Further, in step 4) in, aggregation of resources type dual link between website is disposed to the UE with carrier aggregation function; If UE judges have S-Cell to meet A4 event condition according to S-Cell received power, then send S-CellA4 measurement report to P-Cell, P-Cell sends S-CellAddition signaling to UE afterwards; UE adds this S-Cell as auxiliary community, and second group of receiver starts to monitor SCC corresponding to this S-Cell, carries out physical layer synchronization, carries out layer two Resourse Distribute on two kinds of carrier waves afterwards; All can carry out data transmit-receive between UE and P-Cell and S-Cell after said process completes, service set in SmallCell scope time, can effectively utilize macrocell idling-resource to promote network in general capacity.
Further, in step 5) in, in service set situation, do not have carrier aggregation function UE dual link scene only and P-Cell be associated and carry out data surface transmitting-receiving, P-Cell does not send SCC to it after identifying such UE type and monitors measurement instruction, also would not trigger A4 measurement report and S-CellAddition process.
Further, whether described auxiliary community S-Cell has activation and de-activated mechanism, can according to having transfer of data to need to activate or de-activated S-Cell; Noncontinuity receives DRX, according to different service types and delay requirement setting SCC observation interval, can reduce energy consumption; Can change between S-Cell and non-S-Cell according to service distribution intensity, the unlatching of independent RRC function, closedown.
Beneficial effect of the present invention is: compared with prior art, the method has fully taken into account during isomery cellular network changes for a long time the inefficiency problem brought, make network configuration wide variation environmentally carry out adaptive optimization adjustment, can be applicable to the isomery cellular network that customer service distribution situation has larger change in time.

Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
Fig. 1 is the network scenarios schematic diagram that the present invention is suitable for.There are two type network nodes in this scenario, macro base station and SmallCell base station.Macro base station uses 2Ghz frequency range, and SmallCell base station uses 3.5Ghz frequency range, and therefore MacroCell does not produce co-channel interference to SmallCell user.Because such deployment way main purpose is to increase MacroCell quorum sensing inhibitor regional capacity by the deployment of SmallCell, but not cover border district deployment SmallCell to improve covering at MacroCell, therefore in this scene, SmallCell is deployed in MacroCell and covers area preferably.When user's total amount one timing in scene, if a large number of services is concentrated occur in hot zones, and non-hot zones customer service is little, then macro base station Radio Resource there will be certain free time.And along with passage of time, at some time, change may appear in section business hotspot, a considerable amount of user shifts out Hotspot region, and macro base station resource is utilized again.For school, if dispose MacroCell+SmallCell isomery cellular network in campus after, to attend class in the period a large amount of integrated distribution of customer service in teaching region carry by SmallCell, and outside this region, user is little, and macro base station resource occurs idle; In time at school outside the period, customer service can be distributed in whole campus area relative distribution, and macro base station resource is utilized.If macro base station idling-resource can be used when service set is distributed in hotspot, network capacity can be promoted further.
Similar with inter-frequency networking, need the mode combined by A2-A4 event to increase the utilization rate of S-Cell (being SmallCell in this scene) in such networking scene.Which is described in detail hereinafter.
Fig. 2 is that A2-A4 switching/S-Cell revises criterion schematic diagram.A2 event be current service cell RSS lower than preset threshold value, A4 event is that the RSS of adjacent cell exceedes default threshold value.When adopting inter-frequency networking mode, need rationally to arrange two kinds of threshold values, make A2 event that border occur and in A4 event, border occurs in advance, and the generation border of two kinds of events is all in advance in A3 event boundaries.As shown in Figure 2, as long as within UE is in A4 two border, namely can switch to SmallCell.By configuring rational event trigger thresholds A2_Threshold and A4_Threshold, can make switching that border occurs and be ahead of common A3 event boundaries, UE does not need distance SmallCell base station very closely namely to can switch to SmallCell, increases the utilization rate of SmallCell.When adopting aggregation of resources networking plan between website, the same A2-A4 composition of matter that adopts adds foundation as S-Cell, as long as namely UE adds this SmallCell as S-Cell within being in A4 border.
Fig. 3 is that SON entity draws service distribution flow chart by base station RRC and the analytic statistics of E-SMLC reported data.In order to implement the present invention, need in isomery cellular network to dispose evolved Serving Mobile Location Center E-SMLC (EvolvedServingMobileLocationCenter), and need in SON entity to add service distribution analytic statistics module.E-SMLC collects the measurement result of UE, estimates, the UE positional information of acquisition is sent to the SON entity in network according to these measurement results to UE position; SON entity obtains business state information from base station side simultaneously.According to UE positional information and business state information, SON entity carries out analytic statistics to service distribution, and obtain comparatively accurate service distribution information data, the number of services known in SmallCell overlay area accounts for the total number of services ratio of network.Above-mentioned measurement result collection, UE location estimation, service distribution analytic statistics process need be carried out for a long time, perception service distribution situation rule over time, to be optimized adjustment for the situation of change of long-time interior Different periods service distribution to network parameter.
Concrete steps are as shown in Figure 3:
Step 301:MME gathers the positional information of UE, reports SON entity;
Step 302:SON entity obtains type of service, the configuration parameter information of its association UE from base station;
Step 303:SON entity carries out after business information being combined with UE positional information analyzing, adding up, and obtains and accurate business location distribution information in storage networking scene.This analytic statistics process need carries out for a long time, to obtain comprehensively each time period service distribution situation.Network can carry out specific aim according to the long-time Changing Pattern of service distribution situation to network parameter and optimizes and revises afterwards.
Fig. 4 is under service set is distributed in the prerequisite of SmallCell overlay area, and network carries out P/S-Cell configuration to base station and RRC connection control transfers schematic diagram.
If macro base station learns that the customer service majority (ratio can be arranged) under its covering concentrates on SmallCell overlay area, then network configuration macro base station is P-Cell, and configuration SmallCell is S-Cell.P-Cell issues RRC chain of command transfer instruction by Xn interface to S-Cell, namely retains the data surface of S-Cell, and the original radio bearer connection control of S-CellRRC layer is all transferred P-Cell to and controlled.New control signal is produced by P-Cell, both directly can be sent to UE by P-Cell, also first by P-Cell, signaling can be forwarded to S-Cell by the backhaul between P, S-Cell, then sends signaling to UE by S-Cell.Concrete steps are as shown in Figure 4:
Step 401: macro base station learns current service distribution situation by business positional information memory module, if service set is distributed in the SmallCell area of coverage, then configuration is certainly as P-Cell pattern, backward its cover under SmallCell issue S-Cell configuration-direct, SmallCell is configured to S-Cell after receiving configuration-direct.
Step 402:P-Cell issues RRC configuration-direct by Xn interface to S-Cell, and SmallCell receives the RRC configuration of rear amendment self, cancels independently RRC protocol stack function, only retains independently RLC and MAC protocol stack function.
The connection control of original radio bearer is transferred to P-Cell by step 403:S-Cell.P-Cell is as the RRC anchor point covering lower whole UE, and responsible connection control and signaling produce.
Fig. 5 disposes aggregation of resources type dual link flow chart between website to the UE with carrier aggregation function, specifically comprises CA type UE and sends measurement report to macro base station, macro base station and carry out that S-Cell adds decision-making, SmallCell access control, macro base station changeover section radio bearer, UE add S-Cell, several main process synchronous with S-Cell.
When aggregation of resources type dual link between website is disposed to the UE with carrier aggregation function, if UE finds the A2 event thresholds value of P-Cell received power lower than setting, and S-Cell received power is higher than the A4 event thresholds value of setting, then send A2-A4 measurement report to P-Cell.Predetermined threshold value needs the A2 event ensureing P-Cell to trigger border in advance in the A4 event triggering border of S-Cell.P-Cell thinks after receiving this measurement report that the received power of now S-Cell can meet the qos requirement of UE, sends S-CellAddition signaling to UE.UE adds this S-Cell as auxiliary community, and second group of receiver starts to monitor SCC corresponding to this S-Cell, carries out physical layer synchronization, carries out layer two Resourse Distribute on two kinds of carrier waves afterwards.All can carry out data transmit-receive between UE and P-Cell and S-Cell after said process completes, service set in SmallCell scope time, can effectively utilize macrocell idling-resource to promote network in general capacity.
Step 501: if the UE with carrier aggregation function judges that A2, A4 trigger conditions meets, then send A2, A4 event measurement report to macro base station.Now the S-Cell of this trigger event can meet UEQoS demand.
Step 502: after macro base station receives measurement report, S-CellAddition decision making algorithm module thinks that now S-Cell meets adding conditional, sends add request to S-Cell.
Step 503:S-Cell calls access control module after receiving and adding request and judges whether to allow this UE to access.If admission control algorithm module judges that this UE allows access, then reply S-Cell to macro base station and add acknowledge message.
Step 504: macro base station issues RRC reconfiguration message to UE, UE is configured to PDSCH dual link pattern after receiving the interpolation confirmation from S-Cell.UE adds the auxiliary serving cell of this SmallCell as self, and enables the configuration parameter relevant to this S-Cell.Afterwards the carrying of the partial data of UE is forwarded to S-Cell, self also retains the partial data carrying of UE simultaneously.SNstatus is forwarded to S-Cell by P-Cell, and S-Cell starts buffer memory M-eNB and forwards the packet of coming.
Step 505:UE sends RRC connection reprovision to P-Cell and completes message, and auxiliary receiver starts to monitor SCC corresponding to this S-Cell, carries out physical layer synchronization with S-Cell, and S-Cell carries out layer two Resourse Distribute to this UE.Finally start the data transmit-receive simultaneously carrying out P-Cell and S-Cell.
Need in addition to point out, in the moving process of UE, auxiliary receiver needs to change according to the difference of the RSS intensity of S-Cell the S-Cell accessed, according to being A6 event (RSS of adjacent S-Cell is better than the RSS of service S-Cell).If the RSS of service S-Cell is lower than the S-Cell-A2Threshold of setting, then the quorum sensing inhibitor of this S-Cell cannot ensure the QoS needed for UE, now needs to perform S-CellRemoval operation and removes auxiliary community.Fig. 6 is frequency spectrum resource polymerization overview flow chart between the isomery cellular network station based on service-aware provided by the invention.
What finally illustrate is, above preferred embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although by above preferred embodiment to invention has been detailed description, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from claims of the present invention limited range.
