specific Embodiment

[0064] Methods of controlling CPU utilization include:

[0065] Real-time collection of information such as service rate and packet length distribution calculates the CPU load indicators of each service and saves them; real-time collection of system CPU utilization compares the current CPU utilization value of the system with safety thresholds, maintenance thresholds, overload thresholds and other CPU thresholds; according to calculations The CPU load index of each business is selected, the business that has a large impact on the CPU utilization of the system is selected, the adjustment factor Factor corresponding to each business is calculated, and the maximum downlink data rate quota value of each service selected according to this factor is adjusted to Control the downstream rate of the business, and affect the CPU utilization of the entire system by controlling the throughput of the system.

[0066] Such as image 3 As shown, the specific process of this method in the specific...

Abstract

The invention discloses a method and a base transceiver station for controlling the utilization rate of a central processing unit (CPU). The method comprises the following step of: regulating the highest downlink data rate limit value(s) of one or more services currently maintained by equipment according to the current utilization rate of the CPU of the equipment, thereby regulating the utilization rate of the CPU. By the method and the base transceiver station, the degree of influence of a user or a stream on the utilization rate of the CPU by the concept of CPU load index, and the highest downlink data rate limit value of the service is regulated by utilizing the CPU load index, thereby controlling the utilization rate of the CPU, preventing the overload of the CPU of a system and simultaneously ensuring the smoothness and stability of the utilization rate of the CPU and the full utilization of CPU resources of the system.

Description

Technical field [0001] The present invention relates to mobile communication technology, in particular to a method for controlling CPU utilization and a base transceiver station. Background technique [0002] With the continuous advancement of mobile communication technology, the types of services carried by the mobile communication system are becoming more and more abundant, the business volume is also increasing, the load of the system is heavier, and the system CPU utilization rate is becoming saturated. The current communication system basically has no measures to overload the CPU utilization rate. Under certain extreme conditions, the system CPU utilization rate may be overloaded, and the communication system may be paralyzed in severe cases. [0003] The factors that affect the CPU utilization of the communication system mainly include the following factors: the number of users, data flow rate, and data packet length. [0004] The more users accessing the system, the greater t...
