Problems solved by technology

[0011] In practical application, the above scheme has the following problems: the existing technology cannot guarantee the voice quality of TCH with different rates while taking into account the channel utilization
Obviously, in the prior art, the network side uses the same MAX_LAPDm value to limit the maximum number of cuts of LAPDm frames under different circumstances, and it is unreasonable to prevent the degradation of voice quality on two voice channels with different rates
If the value of MAX_LAPDm is set larger, the user will obviously feel the degradation of voice quality during TCH / H transmission, and if the value of MAX_LAPDm is set smaller, the channel resources of TCH / F may be wasted, and different rates cannot be guaranteed. TCH voice quality while taking into account channel utilization

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] The core of the present invention is that in the dedicated mode, when the user terminal transmits data through TCH / H, it is forbidden to transmit the signaling data of the PS domain on the main DCCH, and only when the user terminal transmits data through TCH / F, the main DCCH is used. The DCCH transmits signaling data in the PS domain, and the user terminal cuts a single upper-layer signaling data block on the main DCCH into LAPDm frames according to the maximum number of LAPDm frames issued by the network side, and then transmits them. In this way, it is avoided that TCHs with different rates use the same maximum number of LAPDm frames to limit the transmission of LAPDm frames on the main DCCH, ensuring the voice quality of TCH / H.

Abstract

The present invention pertaining the mobile communication field discloses a channel transmit limiting method and the user terminal to ensure the voice quality of the half speed service channel. In the present invention, the transmitting of GPRS signaling data of PS domain on the main special control channel is forbidden when the user terminal transmits data through the half speed service channel. The LAPDm biggest frame sends by the network side is only used when the user terminal transmits data through the full speed service channel and the transmitting of the LAPDm frame on the main special channel in the special mode is limited.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the channel transmission limitation of the mobile communication system. Background technique [0002] Communication Channel (Communication Channel) is a path for data transmission. In a communication network, channels are divided into physical channels and logical channels. A physical channel refers to a physical path used to transmit data signals, which is composed of transmission media and related communication equipment; a logical channel refers to a logical connection between the two parties that send and receive data signals through an intermediate node on the basis of a physical channel. A logical path formed for the transmission of data signals. Multiple logical channels can share one physical channel. For example, a Traffic Channel (TCH for short) and a Dedicated Control Channel (DCCH for short) among logical channels may share a physical channel with a 26-multiframe...
