For example, on the one hand, system 900 can be have via one or more communication links (for example, link 932, 934 and/or one or more base stations (for example, base station 922,924 and/or 926) for communicating 936) are in core network entity 910 Communication network.System 900 may include one or more user equipments (UE), such as UE 942,944 and/or 946.For example, On the one hand, UE 942,944 and 946 can be in respectively with base station 922,924 and 926 and communicate.In additional aspect, UE 942,944 It can be resided on a base station with more than one base station communication even if UE is only accounted for each of 946.Additional or can be optionally square Face, network entity 910 can reside in a server or reside on multiple servers to share and/or for loading in event Hinder the redundancy in situation.

On the one hand, base station 922,924 and/or 926 can be small-sized honeycomb cell.As used herein term is " small Type cellular cell " refers to transmission power and/or phase relatively low compared with the transmission power of macro cells and/or the area of coverage To the cellular cell of the lesser area of coverage.Further, term " small-sized honeycomb cell " may include but be not limited to such as femto bee Nest cell, pico cells, access point base station, household B node, femto access point or femtocell etc Cellular cell.For example, macro cells can cover relatively large geographic area, such as, but not limited to several kilometer radius.On the contrary, Small-sized honeycomb cell (such as pico cells) can cover relatively small geographic area, such as, but not limited to building.It replaces Change ground or additionally, small-sized honeycomb cell (such as femtocell) can also cover relatively small geographic area, such as But it is not limited to one layer of family or building.

On the one hand, the distributed device and method updated for self-organizing network are disclosed.For example, on the one hand, The present apparatus and method can update (for example, Distributed coverage and capacity optimization (CCO)) for for the distributed of self-organizing network The information exchange of purpose, and/or for the semanteme of the information exchanged, and/or for calculating the information of exchange, such as above ginseng According to Fig. 4 detailed description.

CCO manages the compromise between covering and capacity effectively with the distribution of aid operators disposition dynamic traffic, design event Barrier and real network operation constraint.For example, radio frequency (RF) parameter of base station radio access network (RAN) performance capacity and Covering aspect plays a crucial role, and finally plays a crucial role to the Quality of experience of user (QoE).Network performance is not only by suboptimum The influence of planning, and influenced by dynamic radio electrical environment, and therefore should dynamically update or adjust radio ginseng Number.In order to assist this situation, 3GPP introduces the CCO use situation for network.CCO identifies covering cavity and high friendship It is folded, and acted by adjusting the radio control parameter of base station to automatically carry out correction.

On the one hand, present disclose provides the distributed method and apparatus updated for self-organizing network.For example, base station One or more nets of the base station can be updated based on the local information received from the feedback of network entity and the base station Network parameter.The feedback received at the network entity can be at the network entity based on real from one or more base stations to the network A part of the data of body transmission determines.

For example, on the one hand, feedback of the base station received from the network entity may include the one or more of the base station Minimum value, maximum value or the value range of network parameter.For example, the network entity can determine bad overlay area, and can determine The base station makes the base station provide the transmitting power lower limit (for example, minimum value) of just suitable covering.It the base station can be based on received from this The lower limit value of network entity and other available local informations of the base station update one or more network parameters with true The proper suitable transmission power of the fixed base station.

As shown in Figure 9 in the commentary, system 900 include multiple base stations 922,924 and/or 926, respectively service UE 942, 944 and/or 946, and it respectively includes updating manager 1002 for executing the distributed of functions described in this article.Example Such as, on the one hand, it is distributed update manager 1002 can be configured to for CCO purpose base station 922,924 and/or 926 it Between exchange information.On the one hand, base station 922,924 and/or 926 directly exchanges long-term in the cellular cell operated about them Cover the information of statistics.In this regard, these statistics are reflected by base station 922,924 and/or 926 and/or by being connected to by base Stand 922,924 and/or 926 operation cellular cell wireless terminal 942,944 and/or 946 collect measurement.

For example, it may include that will use standardization association that distribution, which updates manager 1002, in the one side about information exchange Particular message (the example that view (such as X2AP (3GPP TS 36.423) or S1AP (3GPP TS 36.421)) exchanges between the base stations Such as, CSI-covering statistical information, be adopted name used herein) in information.On the one hand, distributed to update pipe Information can be exchanged via any mechanism in number of mechanisms by managing device 1002, including for example periodically (wherein the period, can be could By network operator configuration), according to base station requests, and/or by specific configurable event triggering (for example, when base station or honeycomb it is small When load in area is more than some threshold value etc.).

On the one hand, about semanteme, it should be noted that distribution, which updates manager 1002, can make base station exchange reflect multifrequency nature In any characteristic covering ASSOCIATE STATISTICS.For example, on the one hand, such statistics can reflect it is following one or more: honeycomb Downlink/uplink covering quality in cell, the downlink/uplink power received, the downlink received Link/uplink interference power, the dl interference power received from particular neighbor, UE transmitted power level, honeycomb Path loss in cell geometric shape, and/or cellular cell.

In further aspect, distribution, which updates manager 1002, intra base station measurement and/or UE measurement report can be used to disappear (MRM) is ceased to calculate covering ASSOCIATE STATISTICS, wherein calculating the time scale of these statistics can be configured by network operator.For example, On the one hand, covering ASSOCIATE STATISTICS can be calculated over a large enough period of time to cover any variation in a variety of variations, including Such as it is following one or more: the load variation of UE geographical distribution variation, serve cell and adjacent cellular cell, and/or UE Mobility pattern variation.

On the one hand, each distributed manager 1002 that updates may include for calculating the covering exchanged between each base station system The standardized mechanism of meter.For example, the definition of each statistics exchanged can be standardized.However, at alternatively or additionally aspect, Method for calculating one or more covering statistics can not be standardized.For example, on the one hand, average cell cell geometry Form can be defined as the number between 0 and 1, wherein lower number is associated with lower geometric shape.For this aspect, base station Then it can simply indicate that its average geometric form is 0.5 by the distributed operation for updating manager 1002, it should without instruction How average geometric form calculates.Similarly, the base station for operating cellular cell ' i ' can declare interference coefficient IC_i,jTo retouch J is received from cellular cell in the i of cellular cell interference level is stated (for example, IC_i,j=0.5), without specifying it is how to calculate 's.In this case, the semanteme (for example, meaning) of each statistics and its range (for example, 0 to 1) can be standardized.

For example, as described above, the distributed base station for updating manager 1002 of operation can be counted from internal measurement and/or UE MRM Calculate covering statistics.In addition, the distributed base station for updating manager 1002 of operation it is configurable by UE that the base station services to collect simultaneously Report the measurement to signal quality.On the one hand, UE can measure the signal of simultaneously report services cellular cell and adjacent cellular cell Quality.For example, base station can configure UE with measure and report it is following one or more: serve cell and/or adjacent cellular cell Reference signal receive the reference signal of power (RSRP) level, serve cell and/or adjacent cellular cell and receive quality (RSRQ) horizontal, radio signal strength instruction (RSSI) is horizontal, UE transmitted power level and by specific protocol (for example, 3GPP TS 36.423) specified other measurements.In addition, it is also noted that these measurement reports can be configured to periodically and/or Trigger-type.

Referring to Fig.1 0, the example distribution formula illustrated in the aspects of the disclosure updates manager 1002.

On the one hand, the distributed manager 1002 that updates may be configured for the distributed update of self-organizing network.Example Such as, on the one hand, each of base station 922,924 and/or 926 can be configured to include distributed update manager 1002. In additional aspect, (base station 922,924 and/or 926) distributed update manager 1002 can be configured to further comprise number According to transfer assembly 1004, feedback reception component 1006 and/or parameter more New Parent 1008.

On the one hand, data transfer assembly 1004 can be configured to the data that base station collection is transmitted in network entity. For example, data transfer assembly 1004 may include transceiver or transmitter or dock with transceiver or transmitter, and/or may include By processor execute software or firmware, and/or may include dedicated programmed processor module.For example, on the one hand, data pass Sending component 1004 can be configured to be transmitted in the data collected at base station 922 to network entity 910.In additional aspect, data are passed Sending component 1004 can be configured to be transmitted in the data collected at base station 924 and/or 926 to network entity 910.Such as above by reference to Described in Fig. 9, the data collected at base station 922,924 and/or 926 may include internal measurement from the base station and/ Or the covering statistics of the MRM received from UE.

For example, on the one hand, can be in these base stations in the data that these base stations are collected from can be with these base stations User equipment (UE) (for example, UE 942,944 and/or 946) in communication is received.In additional aspect, which be can be The combination of small-sized honeycomb cell or macro cells, and/or the two.In terms of additional example, network entity 910 may include center Server, the central server receive the data of the base station transmission from self-organizing network.

It on the one hand, may include that thousands of signalings are reported received from the data for being in the UE communicated with base station.Replacement or Additional aspect, it should be noted that the received data of base station may include from one or more adjacent base stations from this Or the received data of UE of multiple adjacent base station communications.On the one hand, base station can merge received from these UE data (for example, Signaling report) and transmit to network entity 910 (for example, central server) at least part of the data.For example, in additional party Face, base station produce the expression, aggregation or mathematical function of the data (for example, the signaling information received from UE and/or adjacent base station Be averaged) and to network entity 910 send the data expression, aggregation or mathematical function.For example, this allows the network real Body has whole network visual field, rather than by the localization or limited field of the base station maintenance in SON.For example, on the one hand, by network The whole network visual field that entity 910 is safeguarded can be comparable to 15 minutes and/or up to the data on the order of magnitude of twenty four hours, The lasting of the whole network visual field can be and can for example be configured by network operator at network entity 910.

On the one hand, feedback reception component 1006 can be configured to receive from the network entity and join with (all) networks of base station The associated feedback of number, wherein the feedback received from the network entity is to be based at the network entity from the one or more base The data that transmit to the network entity stand to determine.On the one hand, network entity 910 can based on from base station (for example, 922) to The data of network entity transmission determine the feedback for the base station (for example, 922).In additional aspect, network entity may be used also The data received from other base stations (for example, 924 and/or 926) are considered to determine the feedback for being directed to the base station (for example, 922).Example Such as, on the one hand, feedback reception component 1006 may include transceiver or receiver or docked with transceiver or receiver and/ May include by processor execute software or firmware, and/or may include dedicated programmed processor module.For example, in a side Face, the feedback received from network entity 910 can be associated with one or more network parameters of base station (for example, base station 922). In exemplary aspect, these network parameters may include it is following one or more: under the transmission power of the base station, the antenna of the base station Incline and the frequency reuse factor of the base station.

For example, on the one hand, network entity 910 can based on the data transmitted by these base stations according to 3GPP standardize in define Minimum driving test (MDT) regulation identify the coverage gap in self-organizing network.In additional aspect, network entity 910 It can determine the minimum threshold of the network parameter of base station and transmit the minimum threshold to the base station.For example, on the one hand, base station 922 Feedback can be received from network entity 910 to update the transmission power of the base station by minimum value (for example, 200mW) to solve to cover Clearance issues.Can optionally or additional aspect, base station 922 can by be equal to or higher than the minimum threshold received from network entity 910 To update the transmission power of base station 922.

On the one hand, parameter more New Parent 1008 can be configured at least based on received from the network entity feedback and The local information of the base station updates the one or more network parameter of the base station.For example, parameter more New Parent 1008 It may include processor or interfaced, and/or may include the software or firmware, and/or may include specially compiling executed by processor The processor module of journey.For example, on the one hand, parameter more New Parent 1008 can be configured at least based on received from network entity At 910 feedback and base station 922 available local information come update at base station 922 one or more network parameters (for example, The transmission power of base station, antenna have a down dip, and/or the frequency reuse factor).

For example, base station 922 by the operation of parameter more New Parent 1008 can based on can at base station 922 it is locally available attached Addend is according to come the transmission power that updates base station 922, because may and not all can all be transmitted in the available data of the base station To network entity 910, to alleviate any bandwidth and/or processing power problem at the base station and/or the network entity.

On the one hand, local information may include the pilot pollution information of the base station.For example, pilot pollution information may include Report the UE's of multiple strong interferers (for example, relatively strong about such as 5dB or configurable threshold compared with serve cell 922) Number.In additional aspect, local information may include the call failure measured at the serving BS and/or handover failure number Mesh.For example, if call failure and/or handover failure number at base station 922 are higher (for example, more than configurable threshold), Call failure and/or handover failure reason can be then determined from available local information, and can be lost in call failure and/or switching It loses the reason is that due to interfering the power reduced at the base station (for example, base station 922) in increased situation.Can optionally aspect, such as Another base station that fruit meets serve cell selection criterion is unavailable, then does not reduce the function of the base station (for example, base station 922) Rate.

On the one hand, if there are several base stations (for example, small-sized honeycomb cells) in the small area of coverage of SON, it is expected that should In the small-sized honeycomb cell of SON only some small-sized honeycomb cells be transmitted by their maximum power and the SON these are small In type cellular cell remaining small-sized honeycomb cell by lower-wattage (but be equal to or more than the Minimum Threshold received from the network entity Value) it is transmitted to reduce interference and/or improve SINR value.In additional aspect, once base station (for example, small-sized honeycomb cell) from The network entity receives the minimum threshold of network parameter, the small-sized honeycomb cell can operating parameter more New Parent 1008 with into One-step optimization additional parameter (for example, SINR and/or throughput capacity), this may finally lead to better user experience.

For example, on the one hand, if the antenna at base station (for example, base station 922) tilts down, which can be created by force Wave beam simultaneously can make the covering in the region localize.However, the entire area of coverage of the base station may reduce.It alternatively, if should The antenna of base station (for example, base station 922) is tilted upwards or is tilted to horizon, then the base station overlay area can be higher.However, this It may cause and increase with the interference of other base stations and/or UE.For example, it includes under antenna that the base station (for example, base station 922), which can receive, The feedback of the minimum value for parameter of inclining, and the base station of operating parameter more New Parent 1008 can be based on can be locally available in the base station The additional data parameter that will have a down dip be updated to value equal to or higher than the minimum value.

In another exemplary aspect, it includes that minimum frequency reuses that base station (for example, base station 922) can be received from network entity 910 The feedback of parameter, it may include the frequency reuse factor which, which reuses parameter,.In this case, which can operating parameter More New Parent 1008 is updated based in the locally available information of the base station by the minimum frequency reuse factor is equal to or more than The frequency reuse factor.

In additional aspect, the feedback including frequency reuse parameter may include fragment type frequency reuse (FFR) configuration, the fragment Formula frequency reuse (FFR) configuration can further comprise the appointment to the certain priority sequence frequency chunks at different base station.Attached Add aspect, soft FFR may include to the appointment of the certain priority sequence frequency chunks at different base station, and wherein each of base station is excellent First grade sort block is limited with different transmission power.For example, the higher FFR factor can cause base station preferably to cover, still The higher interference generated with higher reuse factor must be taken into consideration in the base station, and selects the value of balance the two.

In additional aspect, when base station receives the feedback including network parameter values range, which may include frequency weight With the lower limit and/or the upper limit of the factor, for the priority ranking frequency chunks number of FFR or priority ranking frequency chunks ordered list Limitation, and/or the transmitted power level different because of frequency chunks limitation.

For example, in additional aspect, the SINR of each UE, data transfer rate, traffic conditions, specific position are (for example, at the center of base station Or adjacent edges) can network locally known in the base station and/or in the operating parameter more New Parent 1008 update base station Parameter is included into consideration when updating with the distribution for the self-organizing network.

In additional aspect, although can define for simplicity in terms of minimum value for changing one or more base stations One or more network parameters the feedback received from network entity, but the feedback received from network entity may include respective wire The minimum value and/or value range of network parameter.
