Problems solved by technology

figure 2 It is a schematic diagram of the protocol conversion performed by the home gateway CPU in the prior art, such as figure 2 As shown, in the wireless uplink service, the home gateway needs to convert the received wireless packet of the 802.11 protocol into an Ethernet data packet of the 802.3 protocol; on the contrary, the home gateway needs to convert the Ethernet data packet of the 802.3 protocol The two-way conversion operation takes up a lot of CPU resources, resulting in high CPU load.
In consideration of factors such as cost reduction, home gateway manufacturers generally do not have too strong CPU processing capabilities. As the wireless download speed increases, it will bring a huge burden to the CPU, which in turn will cause other services of the home gateway to be unavailable. If there are sufficient resources, such as high-priority VOIP service voice quality delay is too large, the call is intermittent, and even the board restarts and other problems
Even if the CPU processing capability is strong, when the wireless throughput reaches the limit, the CPU will be in a high-load state, and it will definitely not be guaranteed to run other services at this time

Abstract

The invention discloses a method and device for improving the voice quality of Internet telephone VOIP. The method includes: detecting that a VOIP user goes off-hook and reporting it; when it is determined that the CPU occupancy of the home gateway when used to send and receive wireless messages is greater than or equal to a predetermined threshold, reducing the sending and receiving rate of wireless messages and the wireless messages entering the home The speed of the gateway CPU. With the help of the technical solution of the present invention, the CPU load can be reduced and the quality of VOIP voice calls can be ensured.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and a device for improving the voice quality of VOIP in network telephone. Background technique [0002] Gigabit passive optical network (GPON) technology is the latest generation of broadband passive optical integrated access standard based on the ITU-TG.984.x standard. It has high bandwidth, high efficiency, large coverage, and quality of service (Quality of Service, QoS for short) guaranteed full-service access, rich user interfaces and many other advantages are regarded by most domestic and foreign operators as an ideal technology to realize broadband and comprehensive transformation of access network services. The GPON technology integrates various technologies such as broadband access, Voice over IP (referred to as VOIP), interactive Internet TV, and cable TV (Community Antenna Television, referred to as CATV). figure 1 is a structural schematic diagram of a GP...
