Implementation method for switching arranged resources in mobile communication system

Abstract

The disclosed method is a mixed implementation method of switching resources in sub zone prearranged in advance and switching resources in time slot prearranged in advance. The invention includes steps: first, executing determination in sub zone level, determining whether idle resource on the current sub zone meets to requirement of prearranged threshold after taking up the new call; if no, refusing the requirement; if yes, then executing determination of time slot level right along; the method determines whether idle resource of time slot meets to requirement of prearranged time slot threshold after taking up the new call or determines whether idle resource of current time slot meets to requirement requested from the switched call; if yes, then taking up the switched call; if no, then re-determining whether to take up the switched call after adjusting each time slot resource. Based on real time load in network, the system adjusts prearranged switching resource dynamically.

Description

technical field [0001] The present invention relates to the control technology in radio resource allocation and handover of cellular mobile communication system, relates to the radio resource reserved for cell handover call in Time Division Duplex / Code Division Multiple Access (TDD-CDMA) mobile communication system more precisely. Resource reservation method, which not only needs to ensure the success rate of switching, guarantee the communication quality of users, and reduce the drop rate, but also avoid resource waste, system resource utilization reduction, and impact on new users due to unreasonable reservation. acceptance success rate. Background technique [0002] In a mobile communication system, after the initial cell is connected to the network, the user terminal may leave the service range of this cell and enter the service range of another cell due to various reasons, and a handover process occurs. The handover process in the TD-SCDMA system is to switch the conne...

Problems solved by technology

[0028] To sum up, the existing resource reservation method mainly adopts a fixed-proportion resource reservation method, which cannot optimize the system resource allocation according to factors such as the load status of the cell, the type of bearer service, and changes in the mobile environment. Two situations occur: if the reserved resources are too small, the needs of switching users in the network cannot be met, resulting in serious call drop of users in the system; if too many resources are reserved for switching users, the resources reserved for new users Resources are reduced accordingly, the success rate of new user acceptance will inevitably decrease, and the utilization rate of system resources will decrease

Therefore, the fixed resource reservation method cannot guarantee that the system will achieve a comprehensive and optimal balance in the three aspects of call drop rate, reception success rate and resource utilization rate.

[0029] The 3G system carries a variety of services, and the rates and service times of various services vary greatly. Whether it is a simple cell reservation or a time slot reservation scheme, if these fixed resource reservation methods are used, the control of resource reservation It is very difficult to optimize the ratio; and the prediction method based on the information statistics of switching users will not be accurate for the system carrying multiple services

The above aspects make it difficult for system resource utilization, admission success rate, blocking rate, handover success rate and other performance indicators to reach the optimal state of the system.
