Embodiment Construction

[0044] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings.

[0045] The method of the present invention includes: (1) in the measurement control command, requiring the UE to use a periodic reporting scheme to measure the correlation value of the common pilot channel (hereinafter referred to as CPICH); (2) the RNC requires the NodeB to perform public measurement and report periodically to reflect the cell The received total broadband power RTWP and the transmitted carrier power TCP of the current uplink and downlink load conditions.

[0046] The present invention makes full use of the measurement results periodically reported by the UE and NodeB in the WCDMA system. In the RNC, the uplink and downlink load conditions of the cells are classified according to the reported values, and at the same time, the wireless environment in which the UE is located is classified, so as to comprehensively determin...

Abstract

The method includes following procedures: based on RTWP and TCP, RNC determines upper limit allowed in up run and downward run in AMR mode; based on measured value of CPICH-Ec / No, RNC determines AMR mode in up run and downward run the single UE expects to use; based on upper limit allowed in up run and downward run in AMR mode as well as AMR mode in up run and downward run UE expects to use, RNC determines AMR mode in up run and downward run utilized by single UE. Comparing AMR modes between UE utilized and current utilized, if they are same, then control command is not needed to send; if AMR modes in up run are different, then adjustment command is sent to UE through message for controlling transmission format; if AMR modes in downward run are different, then adjustment command is sent to side of core network through rate control frame.

Description

technical field [0001] The present invention relates to a voice adaptive multi-rate (Adaptable Multi-Rate) (hereinafter referred to as AMR) rate adjustment method in a Wideband Code Division Multiple Access (WCDMA) system (hereinafter referred to as WCDMA). Wideband power (Received Total Wide band Power) (hereinafter referred to as RTWP), transmitted carrier power (Transmitted Carrier Power) (hereinafter referred to as TCP) and common pilot channel (CommonPilot Channel) chip energy and interference noise power density (hereinafter referred to as CPICH_Ec / No) measured value to determine the rate adjustment method of adaptive multi-rate AMR mode Background technique [0002] With the wide application and rapid development of mobile communication systems, many key technologies in mobile systems are becoming more and more perfect. While realizing normal communication of users, it is also necessary to consider how to obtain the best performance, and obtain the best performance f...
