Method for implementing terminal access and improvement of terminal voice quality

Abstract

The invention discloses a realizing method of both accessing a terminal and increasing terminal voice quality. The method comprises following steps: negotiating services between a terminal and a key station on a control communication channel and lowering the service quality according to capability levels of a supporting terminal which is corresponded with different coding and decoding algorithms by the key station and then enabling the terminal to be accessed into the key station according to the capability levels of the terminal from high to low. The method of the invention can both access the terminal and increase the terminal voice quality evenly, thereby old terminals with low terminal capability levels are accessed into a developed wireless communication system, and simultaneously the speech quality of majority of terminals with higher terminal capability levels can not be affected.

Description

technical field [0001] The invention relates to an access terminal (MS) and a technique for improving MS voice quality, in particular to a method for realizing both access to MS and improving MS voice quality based on control channel service negotiation. Background technique [0002] With the evolution and development of the wireless communication system, improved codec technology improves the coding efficiency of the channel, thereby providing better quality of service (QoS, Quality of Service) for MSs accessing the wireless communication system. A Code Division Multiple Access (CDMA) system is taken as an example for illustration. At present, in the CDMA system, the most commonly used service is the voice service. Voice services have multiple service options, and each service option corresponds to different QoS. The service options commonly used in voice services include: 8K, Enhanced Variable Rate Codec (EVRC, Enhanced Variable Rate Codec), 13K Qualcomm Code Excited Lin...

AI Technical Summary

Problems solved by technology

It can be seen from the fact that the existing technology in the CDMA system cannot take into account the balance between accessing the MS and improving the voice quality of the MS. With the evolution and development of the wireless communication system, although the improved coding and decoding technology can improve the coding efficiency of the channel, it is necessary for the access to the MS. MSs entering the wireless communication system provide better QoS. However, due to the advantages and disadvantages of each codec technology and the different MS capability levels corresponding to different codec technologies, old MS with low MS capability levels cannot access The evolution of the wireless communication system also affects the voice quality of most other MSs with higher capability levels
