Abstract

The invention discloses a voice service upstream resource half persistence scheduling method and a voice service upstream resource half persistence scheduling device directed at a 3G (the 3rd generation telecommunication) / 4G (the fourth generation telecommunication) mobile communication network. The voice service upstream resource half persistence scheduling method directed at the 3G / 4G mobile communication network includes steps: S1, judging channel quality of user equipment; S2, judging whether idle PRB meets demands or not, allocating needed PRB for the idle PRB, if the number of users in a system does not reach the maximum user capacity of voice service of the system, allocating resources to the system by reducing voice coding rate of the existing users in the system, calculating voice coding rate of each user after new user equipment is added, and sending the voice coding rate after being adjusted to all the user equipment, and if not, blocking a call of the user equipment k; S3, detecting upstream channel quality during the communication process: monitoring the upstream channel quality of the user equipment k in real time during the communication process of the user equipment k, and if the upstream channel quality is low, interrupting the call of the user equipment k. The voice service upstream resource half persistence scheduling device directed at the 3G / 4G mobile communication network is used to implement the voice service upstream resource half persistence scheduling method directed at the 3G / 4G mobile communication network. The voice service upstream resource half persistence scheduling method and the voice service upstream resource half persistence scheduling device directed at the 3G / 4G mobile communication network have the advantages of improving resource utilization rate of the system, improving user satisfaction and user capacity and the like.

Description

Technical field [0001] The present invention mainly relates to the field of mobile communication, and specifically refers to a method and device for semi-continuous scheduling of voice service uplink resources for 3G / 4G mobile communication networks. Background technique [0002] The 3rd Generation Partnership Project (3GPP) and the Long Term Evolution (LTE) project started in 2005. Compared with the third-generation mobile communication system, the biggest feature of LTE is a pure packet switching network. The circuit domain in the third-generation mobile communication system is cancelled, and the original circuit-domain services are now carried by the LTE packet domain. [0003] According to different service types, resource scheduling in LTE mainly includes two scheduling algorithms: dynamic scheduling and semi-persistent scheduling. [0004] (1) Dynamic scheduling. [0005] In LTE, for services with low real-time requirements, dynamic scheduling is usually adopted. In LTE, the d...

Problems solved by technology

[0010] 1. Compared with dynamic scheduling, semi-persistent scheduling can make good use of the characteristics of voice services and improve the utilization of system wireless resources. However, in the current semi-persistent scheduling scheme, as long as the system has enough idle resources, it will accept call requests, allocate resources for them, and do not restrict users with poor channel quality during the user's call

This scheduling method will cause users with poor channel quality or users whose channel quality deteriorates during a call, especially users whose channel quality cannot meet the quality of service requirements of voice services to occupy too many wireless resources, thereby reducing the user satisfaction of the system and user capacity

[0011] 2. Although the variable-rate speech coding technology allows users to make full use of the system's wireless resources under different channel conditions, the speech coding rate of the UE is only adjusted according to the user's current channel quality, without consideration from the perspective of the entire system

When the system is in peak hours, users with better channel quality in the system still occupy more resources with a higher speech coding rate, but the newly initiated calls are blocked because there are not enough resources in the system, thus increasing the The call blocking rate of the system limits the user capacity of the system
