- 28. HUAWEITECHNOLOGIES CO., LTD. HUAWEIConfidential Case Analysis A carrier bided for setting up a new radio network. Our company received the bidding on Sep.24, and asked to on Oct.2. The market personnel sent the to a network planning pre-sales engineer on Sep.29 and required them to complete the pre-planning and post-planning of the network based on the bidding. The pre-sales engineer found out that the traffic model condition and network quality requirements are not clear. Besides, the on-site market personnel cannot provide the correct information about the local geographical environment, economy, population, mobile market, customer and market strategy. The pre-sales engineer finished the base station estimation and network planning construction suggestions on Oct.2. The engineer made the estimation of 45 base stations in the first period and 80 base stations in the second period for the market to quote. The market personnel denied the estimation and thought that the estimations do not accord with the actual situation because the number of the base stations are too many, the pressure of the service is heavy and the customers do not accept the estimation. Besides, the estimation does not adapt to the economy development of the country and the actual situation of the customers is not taken into account. The technical suggestions had not embody the network planning scheme.

Besides, dome sites cannot meet the requirements of Search Ring or the sites (For example, the equipment room and the transmission), you need to determine whether to select a new site. If the emulation of the correct site cannot meet the needs of the customer. You need to adjust the site if necessary. After the adjusting, you need to reconnoiter and emulate the site again to achieve the meet the requirements of the customer and export the Network Emulation Report.
- Attention: The Radio Pre-Planning Report after reviewed by the technical support team needs to be confirmed by the market personnel in the regional office. Then, it can be submitted to the customer. The Report Template of Radio Pre-Planning Report must be embodied in the ending of each phase of the pre-planning. When the emulation result is exported, the initial report of the pre-planning must be finished to submit for review by the technical support team and promote the progress of the project. After the previous part, the scale of the local network construction, including number and configuration of the base stations is settled. Then, the Network Pre-Planning Report needs to be written. So far, the network pre-planning phase is complete. But for the commercial network, to-be used in commercial network and the experimental network cannot be used after the previous part. They need be designed based on the parameters of each cell to form the office data can be cut over and loaded. Then the Network Planning Report can be written and a complete network planning is finished. The needs of different carriers are different or some other causes, as a result, the pre-sales, pre-planning and pre-commercial (or commercial and experimental) phases are not coherent. After the pre-planning phase, a local network may have a complete planning needs after a long time. So the result of the pre-planning and whether the needs of the carrier is changed need to be confirmed by the carrier. If necessary, emulate the sites in pre-planning again. If the result of the pre-planning is proper and proved to be available, you can design the parameters of the cells and process the office data to form a complete planning of a local network.
- The cell parameter design includes the following: Position and routing planning RNC area planning Neighborhood tables (neighbor areas of the same frequency, neighbor areas of different frequencies and neighbor areas of different systems) Frequency planning Cell scramble planning Planning of the parameters of the cell channel power Planning of the switchover parameters Permitted parameter planning Guides: W-Operation Guide for Cell Major Scramble-20041101-A-1.0.doc W-Subject Guide Neighborhood Planning-20050316-A-2.0.doc W-Subject Guide Area Planning-20050316-A-2.0.doc W-Guide for Setting System Parameter-20041022-C-1.0.doc Attention: Negotiate with the users or the designing institute about the following items: cell naming rule and coding rule, available frequency range, frequency multiplexing mode小 (for the GSM network) and code planning rule (for both the CDMA and GSM networks), frequency planning of local network boundaries and code planning. For the GSM network, pay attention to the cooperation of the dual band network data. For the network supports both 2G and 3G, focus on the cooperation of mutual operation of different system parameters.
- Based on the integrated network planning report and the cell parameter design, write the Network Planning Report. Submit the report to the project team and technical support team for reviewing. After the review, communicate with the market personnel of the regional office or the area department. Then, the report can be submitted to the users. When the network planning is complete, communicate with the users and report the planning result to make sure that the users know the planning scheme of the planning. Thus, the users can cooperate with us in later project construction phase.
