Embodiment 1

[0066] Please refer to the attached Figure 5 , which is a flowchart of an uplink AMR regulation method disclosed in the present invention, mainly includes the following steps:

[0067] Step S101, according to the transmission format set configured by the network when the current service is established, obtain a currently applicable AMR code rate list.

[0068] The list of currently available AMR code rates obtained by executing step S101 is currently applicable, and the AMR code rates stored therein are sorted from high to low.

[0069] Step S102, obtain the current transmission power of the terminal and the AMR code rate currently used, and judge whether the obtained current transmission power and AMR code rate meet the regulation and decision condition, if yes, execute step S103 or step S104; if not, Then execute step S105 or step S106.

[0070] When step S102 is executed, it is mainly judged based on the acquired current transmit power of the terminal and the currently u...

Abstract

The invention discloses an uplink adaptive multiple rate (AMR) regulation and control method and an AMR regulation and control system. The method comprises the following steps of: acquiring a proper AMR code rate list according to a transmission format set of network configuration in the process of establishing the current services; acquiring the current transmitting power of the terminal and the currently used AMR code rate; regulating and controlling that the currently used AMR code rate is reduced by a level in the AMR code rate list when the transmitting power reaches the maximum transmitting power; and regulating and controlling that the currently used AMR code rate is raised by a level in the AMR code rate list when the transmitting power does not reach the maximum transmitting power and the currently used AMR code rate is positioned at a lower level in the AMR code rate list. The uplink service quality is predicted by utilizing the capacity of the transmitting power of the terminal, so that the control time delay is reduced, and whether the uplink transmitting power is limited is predicted by utilizing the transmission power control (TPC) distributed by the statistical network; and therefore, the AMR code rate is regulated and controlled, the aim of timely improving the quality of speech is fulfilled.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically relates to an uplink AMR regulation method and system. Background technique [0002] In the digital mobile communication system, the wireless communication environment is often complex and changeable. Therefore, based on the changeable channel, in order to provide high-quality voice communication, a voice coding algorithm that can meet higher requirements is required. Adaptive multi-rate (AMR) speech codec technology is used in the current third-generation mobile communication system. Compared with the GSM system, AMR provides an adaptive solution to track the rapidly changing wireless channel environment. According to Adaptively select one of 8 code rates (12.2 / 10.2 / 7.95 / 7.4 / 6.7 / 5.9 / 5.15 / 4.75kbps) for channel quality, so as to achieve the optimal combination of speech coding and channel coding, so as to meet the needs of wireless channels and local cap...
