Abstract

In an example, a self-organizing network (SON) provides automated interfrequency load balancing for a base station such as a NodeB. The NodeB may provide a plurality of carriers, such as in a plurality of UARFCN frequencies, and the SON may provide configuration directives for increasing efficiency. For example, when one carrier becomes loaded, the SON may update neighbor associations to take advantage of relatively unloaded frequency carriers. A plurality of scenarios S may be provided, and a policy P may be defined for each. When the NodeB encounters a scenario S, SON may send configuration directives to implement policy P. Similar concept and policy could be applied in conjunction with INTER Technology Neighbor Definitions between LTE and UMTS and UMTS and GSM. Example if GSM Frequency Neighbors needs to be replaced with different Frequency Neighbors from UMTS based on Load or RF conditions.

specific embodiment of the present disclosure

Hereafter the many different embodiments or example that provide for realizing different characteristic of the present disclosure are disclosed.The concrete example of parts and arrangement is described below to simplify the disclosure.These are certainly only example and are not intended to limit.In addition, the disclosure can in various example repeating label and/or letter.This repetition is to simplify and clearly object, and itself does not indicate the relation between discussed various embodiment and/or configuration.

Different embodiments can have different advantages, but necessarily needs concrete advantage without any embodiment.

Fig. 1 is the block diagram of the mobile network 100 of one or more examples according to this specification.Mobile network 100 comprises subscriber equipment 120, and subscriber equipment 120 is such as couple to radio access network (RAN) 110 communicatedly via wireless antenna 116.RAN110 such as, is couple to core net 130 communicatedly by the voice protocol (VOIP) of Internet protocol.Core net 130 can be connected to different networks again, such as, provide open switched telephone (PSTN) 172 or the Internet 170 of the one or more service of access.In one example, when UE120 participates in call, mobile network 100 provides voice call service by PSTN172.In another example, when UE120 is just performing data manipulation (such as web application, surfing on the net, Email or other network operation), UE120 is being connected to the Internet 170 via mobile network 100.But it should be pointed out that PSTN172 and the Internet 170 are only provided as the example of their respective service types, and the service of other classification can be provided.Therefore, these examples are not intended to mobile network 100 to be restricted in concrete example disclosed in the present application.

In this example, the signal of two kinds transmits in mobile network 100: voice, data and call signal (being referred to herein as " user plane " signal), and control signal (being referred to herein as " control plane " signal).

In a sample scenario, initiate to be passed to RAN110 from the user plane signal of UE120.In RAN110, first user plane signal is received by Node B 112 (or other similar base station), and " calling " is delivered to radio network controller (RNC) 114 by Node B 112.Call Transfer is VOIP data flow by RNC114, and is provided to core net 130.

Core net 130 can be, such as general packet radio service (GPRS) 2G, 3G, 3G+ or other network.In the description, Long Term Evolution (LTE) network (being usually considered to 3G+ or forth generation network) exemplarily uses.But it should be noted that this is not intended to limit, and any suitable network can be substituted.

In this example, core net 130 comprises Serving GPRS Support Node (SGSN) 140 and Gateway GPRS Support Node (GGSN) 142.

SGSN140 can be configured to receive packet from the mobile base station (such as Node B 112) in geographic service area and divide into groups to mobile base station delivering data.SGSN140 can provide Packet routing and transmission, mobile management (connection/separation and location management), Logical Link Management and certification and billing function.Common SGSN function comprises, by the mode of non-limiting example, tunnelling (detunnel) is gone to divide into groups from the GTP of GGSN142 (down link), and IP grouping is worn then towards GGSN142 (up link), carries out mobile management and to user data charging.In the configuration of GSM/EDGE, SGSN140 can provide extra function, comprises in the mode of nonrestrictive example: provide the maximum data rate between every subscriber 60kBd to 150kBd; Be connected to packet control unit; Accept uplink data to form IP grouping; Encryption down link data; Deciphering uplink data; And execution mobile management.

GGSN142 is responsible for the networking between GPRS network and external network (such as the Internet 170).Therefore GGSN142 is from (outward-facing) node the facing of all angles of the Internet 170 and the subnet after being positioned at GGSN142.Therefore, GGSN142 has hidden any GPRS infrastructure found in mobile network 100 from the Internet 170.In exemplary method, GGSN142 receives the data being addressed to particular UE 120, verifies that the UE120 asked is movable on mobile network 100 subsequently.If UE120 is movable, then GGSN142 forwards the data to SGSN140, and data are supplied to UE120 by SGSN140.On the other hand, if UE120 is inactive, then data are dropped.

On the contrary, initiate to arrive GGSN142 from the grouping of UE120, and flow is directed to the correct node (such as correct IP address) on the Internet 170 by GGSN142.It is packet data protocol (PDP) form that GGSN142 can also be able to operate the GPRS packet switched inputted from SGSN140, and sends out them to the Internet 170.In the opposite direction, the pdp address of input packet is converted into the GSM address of UE120.

Although GGSN142 provides directly to the data traffic of the Internet 170, before proceeding to PSTN172, voice flux is first by media gateway (MGW) 138.In this example, MGW138 translates digital media stream between different communication networks (such as the next generation network of PSTN and such as 2G, 2.5G, 3G, 3G+, LTE etc. and so on).This make via multiple host-host protocol across next generation network multimedia communication (such as asynchronous transfer mode (ATM) and IP) become possibility.

MGW138 can be controlled by the Media Gateway Controller function (MGCF) 136 of separating, and MGCF136 provides Call-Control1 and signaling capability.

On the control plane, Node B 112 and RNC114 can provide service by centralized self-organizing network equipment (C-SON) 180 and operations support systems (OSS) 160.One or more distributed SON (dSON) equipment also can be provided, such as, be attached to one or more Node B 112.

Media Gateway Controller functional device (MGCF) 136 is the endpoint devices for (such as between Session initiation Protocol (SIP) and ISDN User Part (ISUP) agreement) switch call agreement.MGCF136 can the resource of control MGW138.

CSCF (CSCF) 134 performs the role of some sip servers or agency, and it is CSCF service and can uses in SIP signaling.

Home subscriber servers (HSS) 132 provides attaching position register (HLR) and authentication center (AuC) two kinds of functions.

SON provide design make the plan of mobile radio access network, configuration, management, optimization and recovery compare manual configuration scheme more simply, automatic technology efficiently.Definition and regulation in the recommendation that SON function and behavior have been produced by such as 3GPP and other tissue.

SON may provide in several different ways, comprises centralized SON (C-SON), distributed SON (dSON) and mixing SON (hSON).

DSON function is distributed between multiple network elements (comprising one or more Node B 112) at network edge place.This provide the function of localization.

C-SON function concentrates on closer to higher-order network node (such as OSS160) usually to allow to the general introduction widely of more multiple edge element and to such as across the coordination of the function of the load and so on of large geographic area.

H-SON is the mixing of centralized and distributed SON, by the wherein elements combination of often kind in hybrid plan.

Advantageously, the function that SON provides, such as:

A. self-configuration.Pattern that self-configuration is striven for " insert and play (plug-and-play) ", thus new base station is automatically configured and is integrated in network, and the New function (comprising new carrier frequency of reaching the standard grade) on base station is also able to Seamless integration-.Self-configuration can be provided to each radio plot by equipment supplier as the part of Software Delivery.Be introduced in network when new base station and open, it is by immediately by Network Recognition and registration.Neighbor base stations adjusts to provide required covering and capacity subsequently automatically, and provides avoiding interference.

B. self-optimization.Base station can comprise the many configuration parameters controlling its operation.Each in these parameters can be adjusted to change network behavior based on to the observation of base station self and both measurements at mobile radio station or handheld device place.Set up automatic neighborhood (ANR) for one in one SON feature, and further feature optimizes the robustness of random access parameter or flowing in the mode switching vibration.A use-case being good at describing the problem automatically closes the base station of certain percentage.Neighbor base stations will reshuffle its parameter subsequently to keep whole region by quorum sensing inhibitor.Just in case increase suddenly for any reason connection requirement, " dormancy " base station is moment " being waken up " almost.This mechanism is the remarkable energy savings of operator.

C. self-regeneration.When some node in a network become can not operate time, self-regeneration mechanism is intended to such as reduce at the cell parameter of neighbours and algorithm (thus other node can support the user that once supported by the node of fault) impact that fault brings by regulating.In legacy network, the base station of breaking down be sometimes be difficult to identify and needs very a large amount of time and resource to repair it.This function of SON allows to find such fault base station immediately, thus takes further measures and guarantee the remarkable deterioration of not presence service for user.

Fig. 2 be according to one or more examples of this specification, the block diagram of Node B 112 medium frequency carrier wave 230.In this example, Node B 112 is communicatively coupled to Femto cell 210, and base station 210 can be any suitable small base station, and such as LTE belongs to eNodeB (HeNB) or similar base station.Should also be noted that some element that can exist equally and the network equipment (such as gateway, Mobility Management Entity (MME) and other network equipment) omit from Fig. 2 and other accompanying drawing for discussing simple and clear object.

In the figure 2 example, carrier wave F1230-1 is assigned to by the frequency carrier of 1087 marks.Carrier wave F2230-2 is assigned to 412 frequency carriers.Carrier wave F3230-3 is assigned to 437 frequency carriers.Carrier wave F4230-4 is assigned to 1062 frequency carriers.Carrier wave F5230-5 is assigned to 612 frequency carriers.

These frequency carrier marks only provide by way of example, and it should be noted that and can use any appropriately combined of carrier wave.In this example, frequency carrier mark is UMTS terrestrial radio access (UTRA) absolute radio frequency number (UARFCN) mark.

The radio frequency that UMTS frequency carrier is used by Universal Mobile Telecommunications System (UMTS) network.Frequency carrier be distributed by management subject, each indicate with the nominal frequency (nominalfrequency) of up link and down link and can comprise earmark.

In the day that this specification is write, UARFCN can check on the internet, such as, exist http:// niviuk.free.fr/umts_band.phpcheck.Example frequency carrier wave is as follows:

Table 1-carrier frequency

These exemplary carrier are used in whole specification, so that the example of intercarrier load balance to be described by means of only the mode of example.But will be appreciated that, the selection of these carrier waves does not limit, and any suitable carrier wave can be used to arrange.

In some embodiment (such as according to the embodiment of UMTS third generation partner program (3GPP) specification), each carrier wave 230 can have " neighbours " relation between two frequencies that is no more than, in this example, be Femto cell 210 and the following UMTS carrier wave disposed.In some known embodiment, these neighborhoods can carry out static definition by engineering process.Among other functions, when the carrier wave that flow points to can not process flow, neighborhood makes flow by " spilling " to neighbours' carrier wave.In addition, in some embodiment of LTE, each carrier wave 230 must have the unique UARFCN communicated with Femto cell 210.

Therefore in the figure 2 example, carrier wave F1230-1 have and Femto cell 210 and and carrier wave F2230-2 frequency between neighborhood.Carrier wave F2230-2 and Femto cell 210 and the neighborhood with carrier wave F3230-3.Carrier wave F3230-3 has and Femto cell 210 and the neighborhood with carrier wave F4230-4.Carrier wave F4230-4 has and Femto cell 210 and the neighborhood with carrier wave F5230-5.Carrier wave F5230-5 has the neighborhood with Femto cell 210, and is circulated back to carrier wave F1230-1, forms closed loop neighborhood system.Femto cell 210 operates on 9938 carrier waves.

As found out in fig. 2, this static arrangement can cause carrier wave 230 not by situation about optimally organizing.Such as, carrier wave F1230-1 and F5230-5 can be designated as " heavy duty (loaded) carrier wave " in this example.This means, these two carrier waves are by addition heavy duty.Carrier wave F2230-2 can be designated as in this example " relative underloading (less-loaded) carrier wave." this means, carrier wave F2230-2 is processing some flows, but the flow handled by it does not have carrier wave F1230-1 and F5230-5 so much.Although therefore carrier wave F2230-2 loads to some extent, it can have more available bandwidth in fact to compare carrier wave F1230-1 and F5230-5.Finally, carrier wave F3230-3 and F4230-4 can be designated as " unloaded (free) carrier wave ".This means, these two carrier waves do not have flow substantially.

It is evident that, this arrangement may cause some difficulty.Such as, the neighborhood between carrier wave F5230-5 and carrier wave F1230-1 may encounter difficulties.Due to carrier wave F1230-1 heavy duty, when carrier wave F5230-5 attempts to provide flow switch, carrier wave F1230-1 may not have the available bandwidth for the treatment of flow.This may cause going offline or packet loss.Meanwhile, carrier wave F3230-3 and F4230-4 keeps completely unloaded, and carrier wave F2230-2 retaining part is unloaded.This may cause the operating condition of the non-optimal of Node B 112, and such operating condition may cause unacceptable network performance.

Go offline, packet loss or other suboptimal networks operation (such as UE120 cannot be connected to network) may have a negative impact to the Key Performance Indicator of network (KPI), this can affect validity and the commercial viability thereof of network.Therefore in certain embodiments, it is useful for improving KPI by raising network efficiency.

In certain embodiments, C-SON180 (be used alone or combine with dSON182 and OSS160 and use) can be provided with policy engine 1624 (Figure 16), and policy engine is provided with the multiple rules for defining sight and corresponding strategies.In one example, provide multiple sight S0...Sn, each sight S can be defined by certain cross section of network condition.Some strategies are also defined by P0...PK.Strategy can be defined as and respond to network condition sight.

C-SON180 or the similar network equipment can comprise the communication interface for coupling with Node B 112, itself comprise telecommunications engine 1526 (Figure 15).Telecommunications engine 1526 can operate provides radio up-line and downlink communication service on multiple frequency carrier, and multiple frequency carrier is configured with the baseline configuration P0 with baseline neighbor relation.

The policy engine 1624 of C-SON180 can operate recognition network condition sight S1; Locate the tactful P1 be associated with sight S1; And providing configuration order based on P1 to telecommunications engine 1526, the neighbor relation wherein between first frequency carrier wave and second frequency carrier wave can be updated to the neighbor relation between first frequency carrier wave and the 3rd frequency carrier.There is provided such configuration by way of example, to illustrate that wherein SON function resides in the embodiment of Node B 112 outside.But, SON function also may be provided in the embodiment of Node B 112 inside.In this case, said procedure can be identical, except communication interface can be Node B 112 inside, instead of arrives the interface of external network.

Fig. 3 be according to one or more examples of this specification, the block diagram of modified Node B 112.In this example, as in the figure 2 example, Node B 112 is couple to Femto cell 210 communicatedly.In the example of fig. 3, carrier wave 230 has the load identical with contacting load disclosed in Fig. 2 separately by way of example.Particularly, carrier wave F1230-1 and F5230-5 heavy duty.The relative underloading of carrier wave F2230-2.Carrier wave F3203-3 and 203-4F4 is unloaded.But in this example, C-SON180 has been provided for the configuration order of the neighborhood of reassigning carrier wave 230 to Node B 112.

Particularly, carrier wave F1230-1 has the relation with carrier wave F3230-3 now, instead of with the neighborhood of carrier wave F2230-2.This allows to flow to unloaded carrier wave F3203-3 from the flooded traffic of heavily loaded carrier wave F1230-1.Similar, carrier wave F5230-5 is circulated back to carrier wave F4230-4, instead of turns back to carrier wave F1230-1.Equally, this permissible flow flows to relative underloading carrier wave.

In certain embodiments, can be appointed as S by needing the sight of reshuffling the multiple carrier waves optimally distributing neighborhood, it has the sight label of such as S1 and so on.The strategy be associated with sight S1 can be there is, as tactful P1.In certain embodiments, C-SON180 can identify sight S1 in advance.Therefore, when C-SON180 determines to run into sight S1, C-SON180 has just had the clear and definite tactful P1 of process sight S1.Particularly, tactful P1 needs neighborhood to carry out upgrading to make heavily loaded carrier wave be associated with relative underloading carrier wave.Ideally, heavily loaded carrier wave is associated with unloaded carrier wave, and relative underloading carrier wave is also associated with unloaded carrier wave.

But will appreciate that, the flow of a great deal of may be directed to unloaded carrier wave (such as unloaded carrier wave F3230-3) by this.Therefore, after a period of time, may be necessary to assess the strategy validity in this particular instance.If find that carrier wave F3230-3 has become heavily loaded carrier wave, then neighborhood may need to be re-equipped and puts to utilize available carrier wave better subsequently.In addition in certain embodiments, C-SON180 can be configured to instructs node B 112 and return its baseline configuration strategy P0 be associated with sight S0.This guarantees that Node B 112 can not rest on and extremely configures a very long time.If network condition deterioration after finding any change, this change can be recovered.

Fig. 4 is the block diagram of the Node B 112 of one or more examples according to this specification.In this example, propose the sight S of interference between wherein may occurring significantly frequently, wherein two frequency carriers have the value significantly separated.Such as, carrier wave F1230-1 and F5230-5 possesses stronger received signal strength indicator symbol (RSSI) and significantly separates on its frequency carrier.Therefore they are designated as " high interference " carrier wave.But carrier wave F2230-2, F3230-3 and F4230-4 have frequency carrier closely, and therefore more may have clean (clean) and contain swash.These carrier waves are designated as the carrier wave of " totally " relatively.Therefore clean carrier wave is grouped in together and avoids high interference carrier wave by definition strategy P.

In this example, carrier wave F1230-1, F2230-2, F3230-3 and F4230-4 is with the tactful P0 linear array of Fig. 1.But in figure 3, carrier wave F4 is not linked to carrier wave F5230-5 downwards, and carrier wave F5230-5 is not fed to loopback to carrier wave F1230-1, this may be the candidate agents of interference.And F5230-5 has the neighborhood with carrier wave F4230-4.Carrier wave F4230-4 feeding is looped back to carrier wave F2230-2, and the closed loop creating clean carrier signal is arranged.Due to flow will allow flow into clean carrier block and can not cascade out, this arrangement contributes to exclusive PCR.

Fig. 5 is the block diagram of the Node B 112 of one or more examples according to this specification.The example of Fig. 5 provides considers the tactful P that power is saved and sight S wherein.Such as, between the special time of a day (time such as at midnight and the morning 6), five carrier waves 230 are provided may to be unnecessary.Therefore, it may be useful for closing one or more carrier wave.In this case, tactful P requires to close down carrier wave F4230-4 and F5230-5 to save power.This makes three carrier waves F1230-1, F2230-2 and F3230-3 can be used for serving Femto cell 210.In the case, carrier wave F1230-1, F2230-2 and F3230-3 are arranged by linear closed-loop mode, thus provide closed loop function.This will guarantee that flow neither flows to carrier wave F4230-4 and also do not flow to carrier wave F5230-5.

Fig. 6 and 7 provides the block diagram of Node B 112, and wherein Microcell 610-1 and 610-2 is also couple to Node B 112 and Femto cell 210 communicatedly.Microcell 610 can be other base station of intergrade, less than Node B 112 greatly than femtocell community 210.Can Microcell be provided, such as, cover limited scope, such as market, office building, hotel or high density shopping centre.In this case, Microcell 610-1 operates on 1087 frequency carriers, just as carrier wave F1230-1.Microcell 610-2 operates on 412 frequency carriers, just as carrier wave F2230-2.Therefore, the connection between Microcell 610-1 and carrier wave 230-1 is considered to (intrafrequency) frequently and connects, and any connection between Microcell 610-1 and any carrier wave except carrier wave F1230-1 connects between being considered to frequently.Similar, the connection between Microcell 610-2 and carrier wave F2230-2 is considered to connect frequently, and the connection between Microcell 610-2 and any carrier wave except carrier wave F2230-2 connects between being considered to frequently.

This sight S introduces extra complexity.Can find out in figure 6, connecting 620 and 624 is frequently be bi-directionally connected.This is because the F1230-1 of carrier wave does not need complete one between " using up (useup) " two frequencies assigned by it in neighbor relation to be associated with Microcell 610-1.Therefore, carrier wave F1230-1 can form the neighbor relation with Microcell 610-1, Microcell 610-2, Femto cell 210 and carrier wave F2230-2.This can cause a large amount of loads to be loaded into carrier wave F1230-1.On the contrary, connecting 622 and 626 between frequency is unidirectional connections.

In order to alleviate this over load, in Fig. 7, remove the feedback loop from heavily loaded carrier wave F5230-5 to 230-1F1.This can prevent heavily loaded carrier wave F5230-5 from continuing extra flow to guide to heavily loaded carrier wave F1230-1.

Fig. 8 and 9 is block diagrams of the Node B 112 of one or more examples according to this specification.In the example of fig. 8, single Microcell 810 is provided.In this case, Microcell 810 operates on the frequency carrier (namely 9938) identical with Femto cell 210.Therefore, all connections to carrier wave 230 are all frequently interior connections.

Figure 10 and 11 is block diagrams of the Node B 112 of one or more examples according to this specification.In this example, carrier wave F1230-1, F2230-2 and F5230-5 provides carrier frequency respective in frequency band 1900.Carrier wave F3230-3 and F4230-4 provides frequency respective in frequency band 850.Owing to having respective UARFCN, these frequency bands are managed and are specified.

In this example, carrier wave F1230-1 and F5230-5 is heavily loaded carrier wave.Carrier wave F2230-2 is relative underloading carrier wave.Carrier wave F3230-3 and 230-4F4 is unloaded carrier wave.In this case, all carrier load occurs in frequency band 1900, does not have carrier load to occur in 850 frequency bands.Therefore, permissible flow is cascaded to carrier wave F1230-1 from carrier wave F5230-5 may not be useful.Because this still makes frequency band 1900 keep too crowded, the neighborhood between carrier wave F1230-1 and F2230-2 is so not useful yet.The loss of KPI can be caused to this loading of frequency band.

In fig. 11, the load on frequency band 1900 is alleviated.In this case, tactful P carrier wave F5230-5 being fed back to carrier wave F3230-3 is provided.This allows network traffics more effectively " to break through " frequency band 1900 and to be cascaded in the available bandwidth on 850 frequency bands.

Figure 14 be according to one or more examples of this specification, for provide automatically frequently between the flow chart of method 1400 of load balance.

The tactful P relevant to each sight is built at some sight of block 1410, C-SON180 predefine.These can be designated as sight S0......Sn and tactful P0...Pk.Each sight S can have the rule for identifying this sight, and each tactful P can have the ancillary rules for implementation strategy P.In one example, following strategy is defined:

The configuration order for tactful P0 is sent to Node B 112 at block 1420, C-SON180.Configuration order is suitable for the necessary information from implementation strategy P0 in Node B 112 to Node B 112 and the instruction that are provided in.It should be pointed out that in this context, implementation strategy P0 not necessarily means direct for tactful P0 literal translation to Node B 112.Although may there is the literal translation to tactful P0 in some cases, Node B 112 receives configuration order and configuration order is translated into the local executable instruction of Node B 112 in the allocation engine of such as allocation engine 1524 (Figure 15) and so on or available commands is also possible in other cases.

Determine whether to detect new sight Sn at block 1430, C-SON180.If new sight Sn do not detected, then continue to maintain baseline strategy P0 at frame 1420, C-SON180 command node B112.At block 1440, if sight changes, then C-SON180 identifies sight Sn and the tactful Pk of association.The mapping that it should be pointed out that between sight Sn and tactful Pk needs not be and maps one to one.Such as, multiple sight can all be mapped to identical strategy.In other example, multiple strategy can be mapped to identical sight, and additional logic can be provided to select in strategy.Therefore, be clearly intended to comprise the situation that there is man-to-man mapping on non-immediate and letter between strategy and sight to the appointment of sight Sn and tactful Pk.

One or more KPI can be measured determine network condition after implementation strategy Pk at block 1450, SON180 whether to improve.This can comprise, such as, measure the signal strength signal intensity of connection, check load balance between each carrier wave 230, check and go offline and packet loss and check the user that cannot be connected to network.But it should be pointed out that other feedback mechanisms many are possible, and be intended to be included in this specification.Therefore, block 1450 represents feedback operation, and wherein whether the change of SON180 decision plan has produced positive effect, counter productive or neutral effect.

If situation is not improved, then control to return block 1420, wherein, baseline strategy P0 can recover.In other cases, control can return block 1440, thus SON180 can judge whether to there is another sight S more conformed to present network conditions.In this case, to correct sight and strategy identification can be iterative process.One or more strategy can apply one or many, and can measure each effect applied to determine that in fact whether it produce positive effect.

At block 1460, provide overtime measure.If there is time-out, then control to return block 1420, and tactful P0 can recover.In this strategy that Node B 112 can be prevented to be absorbed in lower than optimum, the path do not left.Also can prevent C-SON180 from becoming more and more " unused (lazy) " to the use of this time-out.In other words, C-SON180 must constantly reappraise current strategy, to determine whether to deposit the strategy being more suitable for the situation of presence in the operating condition.

At block 1490, method completes.
