Research And Implementation Of IU Interface Routing Optimization Method Based On MSC-POOL

With the continuous expansion of the scale of the mobile communication network between the different standard wireless network interoperability issues highlighted,while the utilization of mobile communication network and core network security requirements have become more sophisticated equipment.MSC POOL technology emerges,MSC POOL break the traditional fixed-wireless network control relationship with the core network of the number of control BSC/RNC's MSC placed in a POOL,MSC POOL within the entire connected BSC/RNC service.UE can be between the RNC in the POOL/BSC roam without having to replace the MSC,signaling resolve the frequent exchange between MSC interface Iu interface and other issues.MSC POOL in convenience and security,but also brought a demand routing algorithm,while the presence of RNC/BSC and MSC POOL routing algorithm many risks,the probability of erroneous routing algorithm leads to subtle connection errors,serious affect customer perception.This Thesis in accordance with the technical specifications of China Mobile Communications Iu interface,considering the efficiency of network elements RNC,stability,and the cost of the software development cycle cost and other factors that support the rapid development of high-efficiency conversion,the conversion process of data quality control technology,achieve a scalable routing algorithm Iu interface.The Iu interface based MSC POOL routing algorithms,support for inter-node wireless network and core network routing a variety of special requirements,the module cost is small,simple and practical functionality to meet the needs of real-time processing.Routing processing system uses frame structure,depending on the type Iu interface forward pass messages were extracted parameters underlying message routing information field goal from the control primitives needed high-level agreements,and ultimately choose the best destination routing.Implementation of the system of internal modular way,to achieve the interaction between layers using primitive methods,strictly in accordance with ITU specification implemented effectively solve the inter-node wireless network and core network routing forward pass messages of various types of choice.The Iu interface based MSC POOL routing algorithm results already existing network investment,a lot of practical application,the application effect is good.The completion of this project is scalable Iu interface routing algorithm is applied to the field of mobile communication networks supporting a worthy attempt for the mobile communications industry needs related to network maintenance solutions provide a meaningful example.
