1. GSM WIRELESS NETWORK PLANNING METHOD 2004年10月21日

2. CONTENT OF NETWORK PLANNING Analysis of the operator’s status Analysis of the operator’s developing environment The stratagem of the operator’s development The goal of the operator’s development Market planning Network planning Finance planning Transmission system planning Wireless network planning Core network planning Network construction project

3. WIRELESS NETWORK PLANNING Wireless network planning Wireless network planning target Coverage target Capacity target Cost target The number of base stations Q1 The number of base stations Q2 Erland capacity of a single cell Link budget Parameters of base stations Investment

4. CONTENT OF PLANNING GSM WIRELESS NETWORK • COVERAGE • TARGET：Coverage probability（populace、geography） • RESULT：The number of the stations Q1、Information of the base stations.(location、altitude、power and antenna bearing) • CAPACITY • TARGET：The number of the subscribers、GOS • RESULT：The number of the base stations Q2、Configurations of the channels.

5. GSM WIRELESS NETWORK PLAN_coverage • Area class • Urban; • Suburban; • Village; • Open area ; • Indoor; • Propagation model emendation • Link budget • Radio coverage of a single cell

6. GSM WIRELESS NETWORK PLAN

7. GSM WIRELESS NETWORK PLAN The considered factors to make certain one subscriber busy hour traffic: • Increase trends in system busy hour traffic ,one subscriber’s busy hour traffic and the relationship between subscriber increase and traffic increase within a year； • Traffic inrease brought by feast day,price policy and data services. Busy hour traffic of one mobile phone Unstable stability of the system busy hour traffic Fluctuation of the system busy hour traffic Analysis of the operator future policy Busy hour traffic of one subscriber

8. GSM WIRELESS NETWORK PLAN_capacity • target：the number of base stations、channels configuration. • process： • Firstly, getting the total traffics by the predicted subscribers; • secondly, analysing the total traffics into every regions; • thirdly,getting the number of the base stations and the configuration of the channels.

9. SUBSCRIBER PREDICTION

10. SERVICE PREDICTION(from up to down）

11. SERVICE PREDICTION（from down to up） Here the subscribers predicted respectively by the way of simple curve fit method、popularization rate method-saturation rate method、relay analysis prediction、analogy method.

12. GSM WIRELESS NETWORK PLAN_capacity • Analysing the total traffics into every regions. • 1、based on proportion of the traffics in existing network of every region ； • 2、statistics of relative increase rate in every region. • 3、result：proportion of traffics in network of every region in the plan period.

13. GSM WIRELESS NETWORK PLAN_capacity • Analysis of feast traffics • purpose：analysis of the peak traffics in every region to reserve some redundant capacity for the peak traffic. • process： • 1、comparing the feasts peak traffics with the weekday peak traffics • 2、ensuring the plan traffics to meet the most busy hour traffics of the plan period.

14. GSM WIRELESS NETWORK PLAN_capacity Analysis of traffic density Space between the base stations in the maximum traffic density area. The wireless network in the area could provide the maximum traffic in the end of the plan period GSM900/GSM1800bi-frequency wireless network plan The traffic density and traffic development in the maximum traffic density area. The maximum traffic density in the end of the plan period.

15. GSM WIRELESS NETWORK PLAN_capacity • Traffics Analysis of the maximum traffic density area. • target：to determine whether to introduce GSM1800 system • process： • 1、according to traffics statistics of about 3km2 area，to get the increase trends of the traffic density in the area and the prediction on traffics density in the area within 3 years. • 2、according to Statistics of the base stations in the area，to get the average distance of the base stations； • 3、according to the bearable traffic density of the different wireless network,to determine whether to introduce the bi-frequency network.

16. GSM WIRELESS NETWORK PLAN_capacity GSM wireless network construction The dimension of the planned wireless network Request of the GSM wireless network • Subscriber prediction； • Subscriber traffics prediction； • The number of base stations in every regions； • The number of the frequencies in every regions； • The number of the base stations for coverage in every regions； • The number of the frequencies for coverage in every regions. CONFIGURATION OF THE EXISTING WIRELESS NETWORK • The configurations of the base stations and the channels in every regions； • The ratio of the base stations for coverage in every regions； • The principle of GPRS dedicated PDCH configuration • The ration of half-rate traffics.

17. GSM WIRELESS NETWORK PLAN_capacity • Target：transfering traffic into channels。 • procedure： • 1、statistics of the cell parameters in every region,including the number of the base stations ,cells,channels etc.； • 2、to make sure the traffic of one channel in every region by looking up reference form； • 3、Dividing the traffics of the every region,educe the number of the voice channels。

18. GSM WIRELESS NETWORK PLAN_capacity • purpose：transfering channels into carriers and base stations. • process： • 1、Considering the influence of BCCH/SDCCH,and GPRS dedicated PDCH； • 2、 With the number of carriers in a cell of existing networks for a reference, transfer voice channels into carriers. • 3、the total channels is divided by the number of channels per site in every region to get the number of the sites. • 4、compared with the number of the existing base stations,to estimate whether the network arrive at the coverage target .

19. GSM WIRELESS NETWORK PLAN_optimization • target： • Enhance use efficiency of network resource and improve network quality of service. • Resolve problem of the network coverage and the traffic imbalance. • Wireless network optimization： • Optimizing base stations location • Adjusting sites type • Adjusting antennas • Adjusting carriers to balance the assigned traffic
