Problems solved by technology

[0007] The parameters carried in the existing Request message and Grant message are only for the single carrier currently in use, and in a multi-carrier system, AT may transmit on multiple reverse carriers at the same time, so if the AT is still in the multi-carrier system The information is transmitted to the AN through the existing Request message, and the AN cannot distinguish which reverse carrier transmits the information; similarly, if the AN still updates the control parameters of the AT through the existing Grant message in the multi-carrier system, the AT will Unable to distinguish which carrier to update the control parameters
[0008] Therefore, the Request message and the Grant message in the prior art are only applicable to a single-carrier system, and cannot realize the information exchange between AT and AN in a multi-carrier system, so that the reverse traffic channel in a multi-carrier EV-DO system cannot be guaranteed. data transfer

Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] In a multi-carrier EV-DO system, the AT can support multiple reverse carrier links for data transmission at the same time, and can support up to 15 reverse carriers. Each AT can also support simultaneous transmission of multiple data streams. In order to control the reverse traffic channel of the multi-carrier EV-DO system, firstly, the data of each data stream needs to be allocated to each reverse carrier through a certain scheduling algorithm, and then through the 1xEV-DO system on each reverse carrier The bucket resource management algorithm in the method manages each flow to obtain the reverse transmission rate on the reverse carrier.

[0041] The main idea of ​​the present invention is to add carrier identification inform...

Abstract

The invention discloses a method to inform carrier transmission information to AN by AT in multicarrier EV-DO system, which comprises: AT composes and send Request information contained label information of every carrier and opposite transmission information to AN; the latter acquires the transmission information according to said label information. It also discloses the method to inform carrier control parameter to AT by AN, which comprises: AN composes and send Grant information contained label information of every carrier and opposite control parameter to AT; the latter acquires the control parameter according to said label information. This invention makes AT and AN match well and ensures the data transmission of inverse business channel.

Description

technical field [0001] The invention relates to the technical field of multi-carrier EV-DO (Evolution-Data Only), more specifically, the invention relates to a method for realizing control information of a multi-carrier EV-DO system reverse traffic channel. Background technique [0002] With the rapid development of Internet Protocol (IP) data networks, in order to support high-speed packet data services on Code Division Multiple Access (CDMA), the concept of EV-DO has been proposed. [0003] In November 2000, the Third Generation Mobile Communications Partnership Project Organization (3GPP) 2 promulgated the 1xEV-DO version 0 standard. 1xEV-DO version 0 uses time division multiplexing technology on the forward link, and adopts adaptive modulation and coding methods, dynamic channel assessment, and hybrid automatic repeat request (ARQ) mechanisms to increase the forward peak rate to 2.4Mbps . In April 2004, the 1xEV-DO version A standard was released. 1xEV-DO version A is ...
