Analysis And Implementation Of The 2/3G Convergence Parameter Optimization

With the development of information technology in the 21 st century, China Mobile is working to build and optimize a TD SCDMA and GSM networks twin situation. This thesis put in the network is technically a TD SCDNIA planning for 3G technology, customers can bring high-speed data access research services, however, due to begin construction of a nearly two years before a TD SCDMA network, in this case, to build business for eleven years has better coverage of GSM network, therefore, 2G/3G interoperable the resulting "2G and 3G interoperability, not only in converged networks raises the need to face, better able to enhance the well consolidated income limit network user satisfaction in fusion," which is the key project in Chengdu, China Mobile investment in the past two years. "This thesis provides an overview of GSM / TD SCDMA a strategy interoperable! Signaling process! Suggestion parameters and other issues, focusing on the GSM / TD a SCD \ IA interoperability policy actions and trigger in-depth study, because switching often occur in the cell coverage area, obtained by comparative analysis based on business and cover-based interoperability features, elaborated the principle of 2G and 3G configuration neighborhood disparate systems interoperability, and introduced to the 2 / 3G neighbor optimization method "in 2G and interoperate with 3G optimization process to regularly carry out coordinated checks of various parameters, ensuring both network parameters set match, reducing communication links, improve network indicators, reduce data conflicts "in the current stage of the game point almost all 2G and 3G interoperability operational optimization of TD has a side to complete, so as TD SCDMA network optimization engineer a TD to either GSM network parameters, or the GSM network to the TD network parameters, we need to verify timely initiative "in the fifth chapter, we developed and realized 2 / 3G convergence parameter optimization system "on the basis of theoretical research, according to the text of the wooden city 2 / 3G develop optimized test systems interoperable, verify the feasibility of interoperability theory, while the test results by the results of applying for interoperability also has an important reference value. "For TD-SCDMA, GSM converged networks affect the user parameter settings because of problems caused by the irrational perception, this thesis details for high-speed scene, TD weak coverage scene, indoor elevator scene, beneath the tunnel scene, pervasive sexual scenes and scenes and other residential areas to achieve convergence parameter optimization approach in 2G / 3G network status, failed to wait for the timer to switch between systems optimized for maximum switching frequency and switching punish failure penalty time optimization, PS domain switching threshold optimization, 2/3G integration capabilities will be able to play the dual network advantage, improve user perception, the formation of long-term coexistence of 2G and 3G, benign complementary pattern. From the user’s perspective, the integration between systems can help users achieve seamless roaming and handover between systems, improve TD network user perception.
