1. Automatic Parameters Optimization (APO) Theory ofOperationThe APO is a group of Self-Organization applications, responsible for maintaining neighbor relationsthrough engineer activities such as adding new cells, or moving cell locations.

The APO supports the following activities:

l Plug & Play - Automatic new site integration in the RAN

l Manual Re-homing - Changing the parent RNC of a cell

The APO application is part of the Cisco Quantum SON framework. These applications enable theOperators to maximize their network resources by offering a quick response to network andenvironmental changes. This dynamic optimization technology uses a unique Network Visibilitycapability to check the current conditions of the network (Snapshot), fine tune the configuration(Action), and test the results (Feedback).

The APO operates before the ANR starts its cycle:

Figure 1: APO-ANR Cycle

1 . Automat ic Parameters Opt im iza t ion (APO) Theory of Opera t ion P lug & Play

Plug & PlayWhen adding new cells to the RAN, Plug & Play creates a complete neighbor list for the new sitesbased on the configured physical distance around the current cell and the azimuth of the neighboringcells (using the same logic as mentioned in the ANR process Matching cell ID to scrambling code).This initial neighbor list gives the cell an initial group of adjacent cells for handover from day one.Further optimization of the neighbor list will be done by the Inter-frequency and Intra-frequencyneighbor relations modules of the ANR when the site goes live.

Figure 2: APO Plug & Play

Cell added to networkCell identified by the SON System viathe OSS synch. SON APO startscalculating neighbor lists.

APO Plug & Play activated automaticallyNeighbor lists added in both directions. Ifnecessary, existing relations are deleted to makeroom for the new relation. If the new cell is on-air, deletion is according to weight. If the newcell is off-air (i.e. weight is not available),deletion is according to distance.

By default, a new cell is configured to be activated for all applications except MEH.

If the APO application is set to OFF, the operational state of a new cell will automatically change from"New" to "Exist" to enable the various applications to work on it. This is the only case in which APOwill not work on a cell.

Figure 3: Plug & Play in Action

APO Plug & Play has the following activation options:

l Automatic activation:When the application is Enabled, it will run automatically and autonomously– creating an initial neighbor list for new cells as they are identified by the system during theperiodic synchronization process. The new cells must be configured in the OSS with their locationID, azimuth, coordinates (which must be within the network/market's geographical area).

l Manual activation: Cells that change locations within the network, e.g. mobile cells (COWs) usedin mass event venues or for disaster recovery, need to be reconfigured for their new location.However, as they are not new cells in the network, the automatic Plug & Play will not be triggeredon them. APO enables to manually change the cell's operational status to "new", causing Plug &Play to run on it on the next snapshot (see Viewing and Changing the Operational Status of Cellson page 16).

New Cell Prerequisites

For Plug & Play to work, the following information must be pre-configured for the new cells:

l Cell Name

l Location ID

l Longitude

l Latitude

l Azimuth


OL-32390-01 3



Missing Location Information

APO will not work on cells with missing location information. If a new cell that is added to an existingRBS is missing the long/lat information, the APO internal algorithm is able to extrapolate the cell'slong/lat from its co-sectors. However, all other mandatory parameters must be configured in order forPlug & Play to operate on the cell.

The algorithm will not work in the following cases:

l If the new cell is in a new RBS, even if the RBS is in the same location as an existing RBS.

l If all other cells in the RBS are also missing the long/lat values.

Plug & Play Indoor Sites

The effective range of indoor cells is considerably lower than outdoor cells and should not be added tothe same distance from other indoor cells. Plug & Play will add indoor cells only up to a distancedefined by the parameter Max Distance for Neighbor Relations from Indoor Cells. Beyond this distance,Plug & Play will add only outdoor cells.

Optimization Following Plug & Play

In order to speed up the automatic optimization of the cell added to the network, following the Plug &Play activity, the cell is marked as in Crisis Mode for a period of two days. If the cell is selected for theANR working list, the ANR will work on it in an aggressive mode.

Creating Intra-frequency Neighbor Relations

The APO Plug & Play system creates intra-frequency neighbor relations to nearby cells, using thefollowing logic:

l It will attempt to create symmetrical relations. If it cannot, the relation will not be created. SeeMaintaining Symmetric Relations on page 6

l The relations are created from the nearest (co-located) to the farthest cells (up to the configureddistance in the Max Distance for Neighbor Relations from Outdoor Cell and Max Distance for NeighborRelations from Indoor Cell parameters).

l Blocked cells, or cells in the “forbidden relations” list will not be affected.

l Cells which do not have beam overlap will not be affected (the Plug & Play cell’s beam radius is theconfigured radius parameter).

l Candidate neighbors that do not have a cell radius (e.g. nearby new cells), but are within the cellradius of the source Plug & Play cell, will receive a default radius of 3 km in order to check beamoverlap.

l Cells which already have relations with the same scrambling code as the Plug & Play cell will notbe affected (these are cases of “second order scrambling code”).


l If possible, the entire intra-frequency neighbor list will be defined (up to the number of relations setby Max Number of Intra-frequency Neighbor Relations) - as long as they are within the configuredmaximum distance.

l In symmetric relations, if a cell’s neighbor list is full, the system will attempt to delete a relation thatfulfills the following requirements:o The cell is not blocked

o The cell has a weight lower than the configured Max Weight for Neighbor Deletiono If relations have no weight, the farthest cells from the source cell are deleted first

o The cell is not in the same RBS as the added cell

If no such cell exists, the relation to/from the relation will not be created.

The priority of cells that are off air will not change.

When introducing a cluster of cells into the network, the nearby cells may not yet be defined in theOSS at the time the application creates neighbor relations for the plug & play cell. In this case, theapplication will add the number of relations defined by Max Number of Intra-frequency NeighborRelations) and it will also add relations to the nearby cells as they are introduced into the system, evenif the cell and/or the candidate neighbors are off-air. In this case, the number of neighbors may exceedMax Number of Intra-frequency Neighbor Relations. If the number of relations reaches the maximumnumber of relations allowed in the neighbor list, the farthest relations will be deleted to make room forthese new relations.

Example - Adding Mult iple Plug & Play Cells

Three new cells are to be introduced into the network: A, B, and C. For illustration purposes, the cellsare defined in the OSS in consecutive days.

Cells A, B, and C are off-air and stay off-air for the next three consecutive days.

In Day 1, cell A is defined in the OSS. Plug & Play is activated as the cell status is "new", and 15neighbors (Max Number of Intra-frequency Neighbor Relations) are created in its neighbor list.

In Day 2, Cell B is defined in the OSS. Plug & Play is activated as the cell status is "new", and 15neighbors (Max Number of Intra-frequency Neighbor Relations) are created in its neighbor list. At thispoint, a relation to cell B is also created in Cell A's neighbor list, totaling the number of relations in A'sneighbor list to 16 (i.e. above Max Number of Intra-frequency Neighbor Relations).

In Day 3, Cell C is defined in the OSS. Here too, relations are added in both A's and B's neighbor lists.

The result is that the NL of cell A and cell B have more neighbor relations created by the applicationthan defined by Max Number of Intra-frequency Neighbor Relations.


OL-32390-01 5



Figure 4: Defining New Cells

Creating Inter-frequency Relations

The system will create Inter relations from the Plug & Play cell to the required Inter-frequency cells inthe area. Such relations will follow the Layer Management Strategy (LMS) as defined by the operator.

Inter relations from the Plug & Play cell are created from the nearest to the farthest cell, according to theLMS policy, similarly to the way intra relations are created (but not symmetrically). The distance forseeking potential neighbors is limited by the Max Distance for Neighbor Relations from Outdoor Cellsparameter

If the system is unable to delete relations from the full NL, Inter relations will not be created.

APO will only operate on cells whose state is "Up". During the synchronization with the OSS, thesystem retrieves the configured state of each cell (Locked/Unlocked, Reserved/Unreserved). A cell isconsidered as "Up" if it is "Unlocked" and "Unreserved" and if it has KPIs from at least 90% of the timein the last hour.

Maintaining Symmetric Relations

The Plug & Play creates and maintains symmetric relations in the neighbor lists.

l For all relations created – the APO Plug & Play creates the reciprocal relation as well

l If the neighbor list that the new cell is to be added to (the to-target) is full, a weaker neighborrelation will be deleted to make room for the new relation

l The same deletion holds true for second order neighbor deletions

l If Plug & Play runs on a cell with existing relations, the application will create any reciprocalrelations required in order to ensure that all relations are symmetrical


Enforcing the Layer Management Strategy (LMS)

The Plug & Play created inter-frequency relations according to the LMS – which is set to enforce thelocal policy.

l For all new relations created – the APO Plug & Play creates relations according to the LMS

l Any pre-existing relations on the cell that do not comply with LMS are removed.

Priority Management

Priority Management for Intra-frequency Relations

Not relevant to NSN.

When compiling a monitored set, the UE compiles the list from the neighbors of the active set cellswith the highest relation priority. Cell relations that do not have the proper priority will not be addedto the monitored set. Priority change is generally based on the intra-frequency weights, with theexception of co-sectors and co-location, which are assigned a higher priority.

The ANR has an option of enhancing the priorities used by the RNC in generating the union set in SoftHandover situations, thus indirectly optimizing the Monitored Set. The application checks the DetectedSet and Unmonitored Set messages as they are created by the RNC. The application then re-evaluatesthe priorities based on the relative weight of the neighbors as reported by UEs connected to the cellbeing checked. This in turn will move required cells from the unmonitored to the monitored set, tobecome available for use as an active cell in the Active Set.

If the priorities are not set correctly, a cell in the unmonitored set could become a strong candidate forhandover, but would be rejected by the RNC since it is not in the Monitored Set. Additionally, cells inthe unmonitored set are more seldom sampled by the UE, therefore it is more likely, especially in fastmoving scenario, that a call could be dropped due to cell not monitored in time.

This module is activated through the Priority application settings.

Newly added intra-frequency relations and newly added Inter relations with Femto cells are assignedthe highest available priority. The priorities assignment application sets relation priorities according tothe weight of the relations which is derived from the handover attempts to each of the relations.

A new neighbor is initially assigned the highest available priority (either by ANR or by APO. Theinitial priority is then recalculated by ANR.

To avoid excessive priority reordering, the existing priority is compared to the new priority. Theneighbor priorities will be updated only in case of a significant change.

The application sets priorities per vendor, as follows:

Priority Management for Inter-frequency Relations

When compiling a monitored set, the UE compiles the list from the neighbors of the active set cellswith the highest relation priority. Cell relations that do not have the proper priority will not be addedto the monitored set. Priority change is generally based on the intra-frequency weights, with theexception of co-sectors and co-location, which are assigned a higher priority.

Each inter-frequency relation is assigned a unique priority between 31 and 62 (where 31 is the highestpriority) in the following order (see vendor specific ranges below):

l Existing undeletable relations

l Tier 1 cells (in borders)

l Co-sector cells

l Co-located cells

l The co-sectors' intra-frequency neighbors prioritized according to their intra-frequency relationweight

l The intra-frequency neighbors' co-sectors prioritized according to their intra-frequency relationweight

l Femto relations are assigned the lowest absolute priorities (57-62). This should take intoconsideration the size of the femto group.

l Other existing relations that are not candidates in the current snapshot but conform to the LMS areselected randomly if there is enough room in the neighbor list.

A new neighbor is initially assigned the highest available priority (either by ANR or by APO. Theinitial priority is then recalculated by ANR.

To avoid excessive priority reordering, the existing priority is compared to the new priority. Theneighbor priorities will be updated only in case of a significant change.

Manual Re-homingQuantum SON offers support to the process of changing the parent RNC of Node Bs, known as re-homing, including all the required changes in the neighbor lists. During the re-homing process, theconfiguration (profiles) of the re-homed cells are copied to the new cells. KPIs are also preserved inorder to maintain the history of SON actions performed before the re-homing.

Supported VendorsThe following equipment vendors are supported:

l Ericsson

l Alcatel-Lucent (ALU)

l NSN

l Huawei

Summary - Activation Examples

The following table summarizes the interaction between the activation options in the ApplicationSettings and in the Module Activation. For the purposes of this example, it is assumed that whateversetting that a group of cells (Group A) has for the activation of an application, all other cells have theopposite setting. So, for example, if App1 is enabled on Group A, then this example assumes that App1is disabled on all other cells.

Obsolete Cells that exist in the database, but no longer exist in the OSS (possibly as a resultof rehoming). These cells are kept in the database to enable monitoring of KPIhistory. None of the SON applications will operate on these cells.

3. Monitoring the Quantum SON ActivitiesThe SON Activities report displays concentric information of all SON activities performed on themarket/region. The information can be drilled-down and filtered according to specific criteria of interest(e.g. a specific RNC, specific KPIs, etc.). The report facilitates network analysis, enabling to takeinformed decisions about the network.

By default, the SON Activities report opens on the market/region level with all applications enabled,displaying actions performed in the last two days.
