• THERE ARE 2 TYPES OF CUSTOMER1.HVS (HIGH VALUE SUBSCRIBER)2.NON-HVS (NON- HIGH VALUE SUBSCRIBER)

• HVS COMPLAINTS ARE AT PRIORITY 1.• NON-HVS COMPLAINTS ARE AT PRIORITY 2.

ACCORDINGLY.

• List of complaints of High Value Subscriber and Non- High Value Subscribers in detail.

• List BBH (bouncing busy hour) reports on daily basis.

• Latest Site data.• Latest Carrier data.• Latest Neighbour data.• Latest RNC Boundaries.• Latest Vector.• List of new sites.

• TABS ARE CREATING BY USING A. MS EXCELB. MCOM

• SITE DATA IS PLOTTED ON MAPINFO.• THEMATIC IS CREATED.

• Database Parameters Changes• Antenna Optimization• Frequency changes• Neighbor addition and deletion• Formation of new location areas• Addition of new cell sites

• Many problems can be solved by changing some database parameters.

• Some of the common changes areA. Handover parameters and thresholdsB. Maximum transmit power of BTSC. Paging parametersD. SDCCH Parameters

• This includes changing of antenna tilts, orientations, positions.

• Sometimes the antenna may also be changed.A. Antenna azimuth is wrong.B. Antenna is connected in a reverse way.

• Frequency changes help us to control the interference in the network.

• However one should be careful when doing changes so that this changes do not affect the other sites adversely.

• If there are a lot of changes it is advisable to change the whole frequency plan.

• A careful study of cell coverage area and server area helps in making those changes.

• Many problems arise due to wrong neighbor definitions or missing neighbors.

• Neighbor definitions must be reviewed on a regular basis. Statistics and drive tests provide good inputs for this purpose.

• Sometimes to solve coverage hole problems we need to add more site (normally micro or pico cells)
