1 Neighboring Cell Planning

Neighboring Cell Planning

Neighboring cell planning affects network performance, and therefore it is critical during radio network planning, especially for the networks requiring quick hard handovers. Appropriate neighboring cell planning helps enhance LTE network performance. In addition, LTE protocols define the automatic neighbor relation (ANR) function, and all Huawei LTE products support ANR.

1.1 Neighboring Cell Planning Principle To perform the ANR function, both the LTE network and the user equipment (UE) must support this function. The effect of ANR is obvious when the traffic is heavy. However, most UEs do not support ANR, and there are a few UEs at the initial deployment stage. Therefore, the initial neighboring cell configuration must be performed by onsite engineers. In addition, in the LTE network, handover measurement is performed by frequency, not by neighboring cell list. After a UE measures cells on the frequency indicated in the measurement configuration, it processes the measurement result to get a candidate handover cell list, and then sends the list to the network. The network selects a cell and initiates a handover. The function of the neighboring cell list is to provide information necessary for handovers, such as the cell global identifier (CGI). Therefore, the number of neighboring cells does not affect the measurement time and accuracy, and a large number of neighboring cells are recommended in the LTE system. The following lists the principles of LTE neighboring cell planning.

2012-03-28



Geographically adjacent cells are used as neighboring cells.



In common scenarios, bidirectional neighboring relationship is configured. For example, if sector B is the neighboring cell of sector A, sector A is also the neighboring cell of sector B. In some special scenarios, for example, a UE moves at a high speed, unidirectional neighboring relationship is configured. To implement a unidirectional handover from sector A to sector B, you can add sector A to the black list of sector B.



The distance between E-UTRAN NodeBs (eNodeBs) is small (0.3 to 1.0 kilometers) in urban areas, and therefore a large number of neighboring cells are recommended. UTRAN refers to universal terrestrial radio access network. Huawei eNodeBs support a maximum of 32 intra-frequency neighboring cells, 64 inter-frequency neighboring cells, or 64 inter-RAT (UTRAN, GERAN, or CDMA2000) neighboring cells. GERAN refers to GSM/EDGE radio access network. When configuring neighboring cells, you must remove unrelated cells.



The distance between eNodeBs is large in suburban areas, and therefore adjacent cells must be used as neighboring cells to ensure timely handovers.

1 Neighboring Cell Planning



The LTE neighboring cells are not in sequence, and the measurement period is short. Therefore, all neighboring cells must be included. The neighboring cells can be sequenced by signal strength or not.



If the adjacent cell of a cell in front of a lake, sea, or a wide road is also in front of the lake, sea, or a wide road, the adjacent cell is configured as its neighboring cell.

1.2 Intra-frequency Neighboring Cell Planning Analysis Intra-frequency neighboring cells are used for handovers in the LTE system. The eNodeB sends the RRC Connection Reconfig message to deliver the intra-frequency measurement configuration when initiates the radio bearer (RB) service. Intra-frequency handover is in a high priority. In actual planning, possible intra-frequency neighboring cells can be put into the neighboring cell list. After initiation, the eNodeB optimizes the neighboring cell relationship based on the UE measurement.

1.3 Inter-frequency Neighboring Cell Planning Analysis In the LTE system, different frequencies are used for capacity expansion, and therefore inter-frequency neighboring cells must be configured. In hierarchical cells, if inter-frequency neighboring cells are configured, the macro cells must be configured as the inter-frequency neighboring cells of the micro cells. In multi-frequency networking, possible inter-frequency neighboring cells can be put into the neighboring cell list. After initiation, the eNodeB optimizes the neighboring cell relationship based on the UE measurement. Hierarchical cells: In heavy-traffic areas, micro cells or micro-micro cells are added to overlap with macro cells to serve more subscribers by taking advantage of geographical areas.

1.4 Inter-RAT Neighboring Cell Planning Analysis In the early stage or in the process of LTE networking, the Wideband Code Division Multiple Access (WCDMA) network may coexist with the Global System for Mobile Communications (GSM), CDMA2000, or Time Division Synchronous Code Division Multiple Access (TD-SCDMA) network. Therefore, the LTE cell must be configured with inter-RAT neighboring cells. The cell is configured as a neighboring cell of an inter-RAT cell. Configuration of different handover parameters ensures continuous coverage and flexible handovers. To make handovers performed only within the LTE network, add inter-RAT neighboring cells to the black list. In the initial deployment of the LTE network, the indoor areas or subways may be covered only by inter-RAT neighboring cells. These cells must be configured as neighboring cells of LTE cells to ensure continuous coverage.

2 Neighboring Cell Planning Solutions

Neighboring Cell Planning Solutions

Neighboring cell planning includes four solutions: neighboring cell planning based on live network data, neighboring cell planning using dedicated tools, neighboring cell planning using pre-planning software, and automatic neighboring cell planning. The LTE neighboring cell planning does not involve dedicated tools.

2.1 Neighboring Cell Planning Based on Live Network Data In actual planning, most operators have networks in other modes, such as the 2G network. The LTE network usually shares one base station with other networks to reduce the cost. New eNodeBs are added only in some special scenarios. In this case, the neighboring cell relationship of previous base stations in other modes can be used to plan the LTE neighboring cells. Figure 2-1 shows the neighboring cell planning procedure based on live network data. The 2G network is used as an example.

2012-03-28

Figure 2-1 Neighboring cell planning procedure based on live network data

Step 1 Complete the LTE cell planning. Step 2 Determine whether the LTE cell and the existing 2G cell share the same base station and the same antenna (or the cells use different antennas, but the antenna engineering parameters are similar). If yes, you can get the mapping between the LTE cell ID and the 2G cell ID based on the 2G cell configuration: 

2012-03-28

When the number of LTE cells equals the number of 2G cells, you can get the mapping between the LTE cell ID and the 2G cell ID directly.

Guide to LTE Neighboring Cell and X2 Interface Planning 


When the number of LTE cells is greater than the number of 2G cells, you can perform the neighboring cell planning for the LTE cells without corresponding 2G cells based on the coverage prediction or drive test result.

If not, you can perform the neighboring cell planning based on the coverage prediction or drive test result, and get the neighboring cell planning result. Step 3 Get the neighboring cell list of corresponding 2G cells based on the 2G cell configuration. Step 4 Convert the 2G neighboring cell list to the LTE cell list based on the mapping between the LTE cell ID and the 2G cell ID. Because the LTE cell list includes both intra-frequency cells and inter-frequency cells, you need to perform the following actions: 

If an intra-frequency neighboring cell list is required, remove all inter-frequency neighboring cells.



If an inter-frequency neighboring cell list is required, remove all intra-frequency neighboring cells.



If an inter-RAT neighboring cell list is required, configure all 2G neighboring cells as inter-RAT neighboring cells. Then, get the initial LTE neighboring cell planning result.

Step 5 If a new eNodeB is deployed around or the co–eNodeB cells cannot use the existing neighboring cell data, configure neighboring cell relationships for these cells. Step 6 If there are more than 32 initial neighboring cells, remove the neighboring cells that have few handovers to the host cell based on the 2G cell handover data to ensure the number of neighboring cells is not more than 32. Following these steps, you can get the planning results of intra-frequency neighboring cells, inter-frequency neighboring cells, and inter-RAT neighboring cells. 

The 2G neighboring cell relationship can be converted to the LTE neighboring cell relationship according to the following procedure:

a)

Open the neighboring cell relationship database and export the data of 2G neighboring cell relationship to an .xls file.

b)

Replace the 2G cell ID with the corresponding LTE cell ID to get the initial LTE neighboring cell relationship.

c)

Filter the intra-frequency, inter-frequency, or inter-RAT neighboring cells.



The bidirectional neighboring cell relationship must be configured for the following cells: − Cells of new eNodeBs − Co-eNodeB cells that cannot use the existing neighboring cell data



This neighboring cell planning solution applies to scenarios where new eNodeBs are deployed. If a large number of cells do not share a base station, another neighboring cell planning solution is needed, which makes the planning complicated. In this case, other neighboring cell planning solutions are recommended.

This solution applies to initial neighboring cell planning at the initial deployment stage. The initial neighboring cell plan is optimized and adjusted based on the network performance in following days. The terrain feature information and the propagation model in the 3D digital map facilitate the neighboring cell planning. Currently, Huawei uses the U-Net tool to plan neighboring cells. The U-Net supports automatic neighboring cell planning. In addition, it also supports the neighboring cell planning in scenarios where the repeater or remote radio unit (RRU) is used. This ensures the planning reliability. The U-Net plans the neighboring cells based on the following principles: 

The cells that are served by the same eNodeB with the local cell are configured as the neighboring cells of the local cell.



The candidate neighboring cells that have high scores are configured as the neighboring cells of the local cell.



The existing neighboring cell relationship is reserved.



The bidirectional neighboring cell relationship is configured.

The U-Net neighboring cell planning is based on the topology or coverage prediction, or both of them. 

Neighboring cell planning algorithm based on the coverage prediction

Divide the space around the base station into multiple areas, forming a coverage matrix. Calculate the counters at the matrix node, and plan neighboring cell relationship based on the sequence of the counters. 

Neighboring cell planning algorithm based on the topology

Use the cell to be planned as the center, calculate the angel and distance between the cell to be planned and the candidate cells, and then plan the neighboring cell relationship. 

Neighboring cell planning algorithm based on the coverage prediction and topology

Plan neighboring cell relationships based on the coverage prediction. If the neighboring cells cannot be planned based on coverage prediction, plan neighboring cell relationships based on the topology. Neighboring cell planning using the GENEX U-Net V300R007C00SPC200 is used as an example. The U-Net is used in following modes: 

Code Division Multiple Access (CDMA), GSM, Universal Mobile Telecommunications System (UMTS), LTE-TDD, or LTE-FDD



Co-eNodeB GSM, UMTS, and LTE-FDD

The CDMA or LTE-TDD mode supports only single-mode neighboring cell planning.

area, and provides the information about the wave transmission environment for the coverage prediction. By setting a proper transmission mode, you can predict the path loss, and then prepare the coverage prediction map and the neighboring cell planning result. 2)

Engineering parameter table

The engineering parameter table includes the base station geographic distribution information, including the site latitude and longitude, antenna height, angel, and antenna length, which affect the coverage and the handover area.

The digital map is not mandatory. If no digital map is available, you can import an engineering parameter table to the U-Net, and perform prediction based on the site position, azimuth, tilt, and antenna installation height. The engineering parameter table is not dedicated for the neighboring cell planning. If the planning is not based on the digital map, the planning result is not accurate.

The ANR function is to use UE measurement to detect cells lack of neighboring cell relationship, which applies to the network with a large number of UEs. There are a few UEs at the initial deployment stage, and most UEs do not support ANR. Therefore, the neighboring cell planning using tools is recommended.

X2 Interface Planning

Based on the neighboring cell relationship, the X2 interface planning configures an X2 link between two eNodeBs with handover relationships. An eNodeB can be configured with a maximum of 32 X2 links, and the X2 link is bidirectional. The X2 interface links two eNodeBs. Therefore, the eNodeB neighboring relation table is provided by the network planners based on the neighboring cell relationships. The engineers on the RAN side configure X2 links according to the following table. Table 3-1 X2 interfaces between eNodeBs Central eNodeB

3 X2 Interface Planning

In the N4M site, X2INTERFACEID, X2SCTPLINKID, SCTPNO, PATHID, and ANI use numbers from 0 to 47 as the ID numbers. Parameters with ID numbers from 0 to 15 are reserved for the core network, and those with ID numbers from 16 to 47 are reserved for the X2 interface. The X2 interface configuration is bidirectional, and therefore you must check the X2 relationships that are obtained from the neighboring cell list. If there is unidirectional X2 relationship, you must change it to bidirectional relationship. Then, use ID Get v1.0.xls to extract the IDs. For details about the ID Get v1.0.xls, refer to the following website: http://support.huawei.com/support/pages/kbcenter/view/product.do?actionFlag=detailCaseDo c&web_doc_id=SC0000617191&doc_type=CaseDoc

1.

Ensure that the following conditions are met before preparing scripts for intra-frequency neighboring cells:

a)

The engineering parameter table is prepared based on the template (see the attachment in section 4.5.1 CME) and the parameters in the table are complete and correct.

b)

Neighboring cell planning is completed, and the planning results are in the format as shown in the following figure.



In the neighboring cell configuration, LocalCellID for the local cell is used to search for CellID for the neighboring cell. However, for tool-based neighboring cell configuration, CellID for the local cell is used to search for CellID for the neighboring cell. To avoid confusion, the value of LocalCellID is the same as that of CellID in actual planning.



NSiteName indicates the site name of a neighboring cell. N is short for neighbor, which has the same meaning in NeNBID, NCellID, NPCI, and NTAC. The neighboring cell physical cell identifier (PCI) and tracking area code (TAC) are provided because the information is necessary when the neighboring cells of different eNodeBs are configured with external cells. When a local cell and its intra-frequency neighboring cells are served by different eNodeBs, the corresponding external evolved universal terrestrial radio access network (E-UTRAN) cells must be configured in advance.

The DL EARFCN is calculated by using the following formula: DL carrier frequency (MHz) = Lowest frequency of the DL operating band + 0.1 x (DL EARFCN - Offset used to calculate the DL EARFCN). For example, if the DL EARFCN is 3100 in band 7 for a cell, the DL carrier frequency of the cell is calculated as 2620 + 0.1 x (3100 - 2750) = 2655 MHz. Band 1: DL EARFCN range: 0 to 599, lowest frequency of the DL operating band: 2110; Band 2: DL EARFCN range: 600 to 1199, lowest frequency of the DL operating band: 1930; Band 3: DL EARFCN range: 1200 to 1949, lowest frequency of the DL operating band: 1805; Band 4: DL EARFCN range: 1950 to 2399, lowest frequency of the DL operating band: 2110; Band 5: DL EARFCN range: 2400 to 2649, lowest frequency of the DL operating band: 869; Band 6: DL EARFCN range: 2650 to 2749, lowest frequency of the DL operating band: 875; Band 7: DL EARFCN range: 2750 to 3449, lowest frequency of the DL operating band: 2620;

CellReselPrio rity

Inter frequency cell resel priority

Meaning: Indicates the cell reselection priority of the neighboring E-UTRAN frequency. It is contained in system information block type 5 (SIB5). The UE decides whether to reselect a neighboring cell on the frequency based on the value of this parameter and the absolute priority of the serving cell. If the value of this parameter is larger than the absolute priority of the serving cell, the UE starts measurements on neighboring cells on the frequency; then if the signal quality of some neighboring cells meets the related conditions, the UE starts cell reselection. If the value of this parameter is smaller than the absolute priority of the serving cell, the UE starts the measurements only when the signal quality of the serving cell is poor; then if the signal quality of some neighboring cells meets the related conditions, the UE starts cell reselection. Frequencies used for different RATs must be assigned different cell reselection priorities. For details, see 3GPP TS 36.331. GUI Value Range: 0~7 Unit: None Actual Value Range: 0~7 MML Default Value: 1 Recommended Value: 1 Parameter Relationship: If CellReselPriorityCfgInd is set to CFG, CellReselPriority must be set.

CellReselPriorit y

Cell reselection priority

Meaning: The UE decides whether to reselect a neighboring cell on the UTRAN frequency based on the value of this parameter and the absolute priority of the serving cell. If the value of this parameter is larger than the absolute priority of the serving cell, the UE starts measurements on neighboring cells on the UTRAN frequency; then if the signal quality of some neighboring cells meets the related conditions, the UE starts cell reselection. If the value of this parameter is smaller than the absolute priority of the serving cell, the UE starts the measurements only when the signal quality of the serving cell is poor; then if the signal quality of some neighboring cells meets the related conditions, the UE starts cell reselection. Frequencies used for different RATs must be assigned different cell reselection priorities. For details, see 3GPP TS 36.331. GUI Value Range: 0~7 Unit: None Actual Value Range: 0~7 MML Default Value: 1 Recommended Value: 1 Parameter Relationship: If CellReselPriorityCfgInd is set to CFG, CellReselPriority must be set. Service Interrupted After Modification: No (And no impact on the UE in idle mode) Impact on Radio Network Performance: A larger value of this parameter leads to a higher probability of starting measurements on neighboring cells on the UTRAN frequency and also a higher probability of reselection to a neighboring cell on the frequency.

Frequency offset

Meaning: Indicates the frequency offset of the cell on the UTRAN frequency. It determines the probability of triggering measurement reports for event B1. For details, see 3GPP TS 36.331. GUI Value Range: -15~15 Unit: dB Actual Value Range: -15~15 MML Default Value: 0 Recommended Value: 0 Parameter Relationship: None Service Interrupted After Modification: No (And no impact on the UE in idle mode) Impact on Radio Network Performance: The entering condition of event B1 is as follows: Mn + Ofn - Hys > Thresh. Where, Mn is the measurement value of neighboring cells, Ofn is the frequency-specific offset of the neighboring cell. Thresh is the threshold for event B1. Hys is the hysteresis for event B1. A smaller value of Ofn results in a lower probability of triggering an event B1. This may delay the handover and affect the user experience. A larger value of Ofn leads to a higher probability of triggering an event B1, which may cause handover decision errors and ping-pong handovers.

Qqualmin

Minimum required quality level

Meaning: Indicates the minimum quality level required for a cell on the UTRAN frequency to become a candidate for reselection. This parameter is applied only to reselection to UTRAN FDD cells. A neighboring cell on the UTRAN frequency can become a candidate for reselection only when the signal quality of the cell is better than the value of this parameter.

4.4 Script Preparation in RAN-Sharing Mode In this document, the RAN-sharing mode includes RAN sharing with common carrier and RAN sharing with dedicated carrier. In RAN sharing with common carrier, multiple operators share eRAN resources that include carriers and eNodeB hardware. In RAN sharing with dedicated carrier, different operators have their own carriers and share only eNodeB hardware. The Multi-Operator Core Network (MOCN) uses the RAN sharing with common carrier.



For co-eNodeB neighboring cells, the configuration procedure is the same as that in section 4.1 Script Preparation for Intra-Frequency Neighboring Cells.



For intra-eNodeB neighboring cells, if the target cell is in RAN sharing with common carrier, the neighboring cells can be shared after the PLMN list of an external cell is added.



The target cells not in RAN sharing with common carrier are separated based on the E-UTRAN cell global identifier (ECGI) that includes MCC, MNC, eNodeBID and CellID. The number of intra-frequency neighboring cells is 32 and is fixed.

Add the PLMN list of external E-UTRAN cells by running the following command: ADD EUTRANEXTERNALCELLPLMN: Mcc="460", Mnc="20", eNodeBId=255, CellId=1, ShareMcc="460", ShareMnc="01" Table 4-17 lists related parameters. 

4.4.2 Neighboring Cell Configuration in RAN Sharing with Dedicated Carrier The neighboring cell configuration in RAN sharing with dedicated carrier applies to the scenario that operators use different frequencies and share only eNodeB hardware. The neighboring cell configuration in RAN sharing with dedicated carrier does not affect neighboring cell planning and configuration.

4.5 Script Preparation for Neighboring Cells in Batches 4.5.1 CME At the initial deployment stage, provide data to radio network engineers based on the Configuration Management Express (CME) Radio Network Planning (RNP) template Configure neighboring cells when the site is deployed. For the inter-RAT neighboring cell configuration, the CMEV200R011C00SPC200 supports only the GERAN network, and the CMEV200R011C00SPC220 supports only the UTRAN network. For details about the CME RNP template, see the following attachment.
