Description

A service admission control method and base station

technical field

The invention relates to the technical field of wireless communication, in particular to a service admission control method and a base station.

Background technique

In communication technology, the admission control method is to maintain the stability of the communication system. When the communication system receives a new service request, it needs to decide whether to accept the new service according to the resource requirements of the new service request, the current resource usage status of the cell, etc. request; at the same time, in the case of resource permitting, access as many services as possible, so as to make full use of communication system resources and ensure the quality of service (Quality of Service, QoS) of users. With the development of mobile communication technology, the Long Term Evolution (LTE) system is an important development direction of the post-3G (third generation mobile communication technology). As far as the system is concerned, there are two conflicting performance requirements: on the one hand, it is necessary to maintain the resource utilization rate of the system, and on the other hand, it is necessary to ensure the best quality of service for the accepted diversified services. Obviously, both must be taken into account, and a balance point needs to be found through an effective admission control algorithm to meet as many business requirements as possible while maintaining a high level of resource utilization.

The first-generation and second-generation mobile communication systems mainly provide voice services. For users, call interruption is more unacceptable than call rejection. Therefore, the usual practice is to combine the connection request initiated by the handover Treat them differently and process switching requests with priority. In addition to supporting traditional voice services, the LTE system also supports multiple broadband data services, such as multimedia services. Therefore, the admission control strategy can no longer just focus on the compromise between the handoff drop rate and the blocking rate, and it is necessary to formulate a reasonable strategy according to the characteristics of diversified services.

The prior art solution discloses a downlink hard resource admission control method in an LTE system, including: receiving the average RB occupancy rate and average modulation and coding efficiency reported by the MAC measurement device; using the average modulation and coding efficiency to predict and estimate the RB of a new access service Occupancy rate; calculate the sum of the average RB occupancy rate reported by the MAC measuring device and the RB occupancy rate estimated by the new service, and compare it with the admission threshold; when the sum of the average RB occupancy rate reported by the MAC and the RB occupancy rate estimated by the new service is less than The new access service is allowed to be admitted when the admission threshold is reached. Corresponding systems and devices are also provided. The technical solution of the present invention uses the average RB occupancy rate and average modulation and coding efficiency measured and reported by the MAC measurement device to compare the relationship between the RB occupancy rate and the average RB occupancy rate of new access services and the threshold. Improve user satisfaction by comparing QoS requirements for controlling whether to accept new access services.
