Rules
Optimizer rules can be used to fill missing bidirectional and same site adjacencies and mandatory constraints
Mandatory constraint should always have an adjacency
Forbidden constraint should NOT have an adjacency
Same site cells should always have mutual adjacencies
All adjacencies should be bidirectional
One rule is used to delete existing adjacencies with forbidden constraint
Resulting correction plan can be used also for distance-based creation

Common Parameters
Create bidirectionality is recommended
• Both ADJW and ADJG types need to be in the scope for this
Changes should be enabled between the scope and buffer area
Minimum and maximum adjacency list lengths can be modified
In GSM optimization the user can
define band-specific list length
limitations
Go to Creation parameters

Allowed Collisions in Creation
In typical Adjacency optimization plan NO collisions are allowed
• Existing collisions prevent creation of the same type adjacencies for the cell -> Allow collisions to create new adjacencies
![Page 18: Training Material Distance Based Adjacency Creation for GSM and WCDMA OPT 3.1 CD2 v2](https://reader034.vdocuments.site/reader034/viewer/2022051117/5695d0321a28ab9b0291690b/html5/thumbnails/18.jpg)

Adjacency Creation Parameters
For ADJS, ADJG and ADJI select only one plan based on distance and specify
• distance between the sites
• relative angle of antennas (see next slide)
Distances and angles can be different for each type
![Page 19: Training Material Distance Based Adjacency Creation for GSM and WCDMA OPT 3.1 CD2 v2](https://reader034.vdocuments.site/reader034/viewer/2022051117/5695d0321a28ab9b0291690b/html5/thumbnails/19.jpg)

Angle measurement starts from the line connecting the sites
Measurement always to shortest route
Theta angle: q = a + b

Creation Priority
Adjacencies to be created or deleted are in the order of importance based on the distance and theta angle
Distance and theta angle can be adjusted for the next round of optimization
Manually created adjacencies in the same plan are included in this list
