Embodiment Construction

[0029] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. Process such as Figure 4 shown.

[0030] The invention proposes a mixed resource allocation scheme for the VoIP service, and automatically distinguishes the state of the voice service in the wireless or mobile network by judging the data volume of the voice service in the buffer area. For each state, intelligently select different corresponding "integration of dynamic scheduling and semi-persistent scheduling" methods to meet the system-level performance requirements of voice services in wireless or mobile networks and reduce signaling overhead.

[0031] VoIP services are divided into uplink and downlink directions. For the downlink direction, the scheduler at the base station side can accurately know the data volume of the voice service in the data buffer area. We use BUFFER DL Indicates the data volume of the downlink voice s...

Abstract

The invention discloses a method for carrying out mixed resource distribution on voice over Internet protocol (VoIP) service. The method can comprise the following steps that: when users are in an activation period, a base station allocates semi-continuous wireless resources for the users; after the allocation of the semi-continuous wireless resources by the base station is completed, the rest data quantity of a downlink buffer region and the reset data quantity of an uplink buffer region are judged, when the rest data quantity of the downlink buffer region and the reset data quantity of the uplink buffer region are greater than a certain threshold, the base station is on the semi-continuous dispatching basis, the base station can carry out once dynamic dispatching on users, the resources are allocated, and the rest data is transmitted; and when the users are in a quiesce period or a transient period, the base station recovers the semi-continuous resources allocated to the users, and the resources are allocated to the users through dynamic dispatching. The network state is distinguished through the judgment on the data quantity of voice service in the buffer region, and the flexible dispatching strategy and the self-adaptive resource allocation strategy are adopted, so the resource utilization rate can be improved on the basis of ensuing the dispatching signaling expenses, and in addition, the waiting time delay of voice data packets can be reduced.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method for allocating mixed resources to VoIP services. Background technique [0002] For the fourth-generation mobile communication LTE (Long-Term Evolution, long-term evolution) system, all services are assembled into IP data packets, and after being scheduled and resource allocated by the scheduler of the base station, they are transmitted on the shared channel. For the traditional voice service, it is carried by VoIP (Voice over IP, VoIP) in the LTE system. [0003] VolP voice service is mainly divided into 3 states: transient period, active period and quiet period, and transient period refers to the period when the voice data packet is not compressed at the PDCP (Packet Data Convergence Protocol) layer. The size of the voice data packet is relatively large. The active period refers to the period after the PDCP layer compresses the header of the voice data packet, and the si...
