Abstract
The invention discloses a method and a device for controlling data sending of an access terminal. The method comprises the following steps: detect whether a reverse business package is sent by the access terminal in a reverse link silence period by an access network; when the reverse business package is sent by the access terminal in a reverse link silence period, which is detected by the access network, the access terminal is recorded into a limit access range and is refused to access the access network when the access terminal requests. In the technical proposal, the access terminal is detected to send business data in the reverse link silence period and the exception handling is carried out to the access terminal, thereby safeguarding the network security.
Description
Technical field
The present invention relates generally to the mobile communication technology field, is meant that especially a kind of control in CDMA 1xEVDO RevA wireless communication system accesses terminal at the method and the device of reverse link quiet period transmission data.
Background technology
Based on CDMA (Code-Division Multiple Access, code division multiple access) in the wireless communication system of 1xEVDO (Evolution, Data Only) RevA, reverse link silence period in the standard agreement (Reverse Link Silence Period) and reverse link (Reverse LinkSilence Duration) two parameters of mourning in silence the duration are used for accurate measure R OT (Rise-Over-Thermal, hot noise increase) value, reverse link is according to ROT value Resources allocation.
Wherein reverse link silence period and reverse link duration two parameters of mourning in silence are standard agreement parameters, these two parameters are by access network (Access Network, AN) side is set to the high pass chip and is used to calculate reverse link quiet period time interval based on cdma system time measurement ROT value, AN sends these two parameters to (the Access Terminal that accesses terminal by Overhead Message simultaneously, AT), require AT (to suppose that the reverse link silence period is 100 time slots in reverse link quiet period based on the cdma system time, reverse link duration of mourning in silence is 16 time slots in these 100 time slots, then reverse link is mourned in silence index futures is exactly mourn in silence these 16 time slots intervals of duration of reverse link in 100 time slots of reverse link silence period) in do not allow to send the reverse traffic data, help accurately measuring the ROT value like this.
From the above description as can be known, the ROT value is being controlled the resource allocation of reverse link, and only in the reverse link silence period, could measure the ROT value accurately, so whether AT sends the accuracy that business datum will have influence on measure R OT value in the reverse link silence period, thereby influence the distribution of reverse link resources.
CDMA 1xEVDO RevA system can not guarantee to be exactly real reverse link situation for the ROT value of measuring in the reverse link silence period at present, because the ROT value that AN measures is based on AT and does not send pilot power under the business datum condition in the reverse link silence period, AN can not directly control AT can send business datum scarcely in the reverse link silence period.Can not align 1, because of AT system time and AN system time, cause AT in the reverse link quiet period, to send business datum, 2, terminal equipment problem 3, people send in the reverse link quiet period under these several situations of business datum for taking terminal, the AN lateral root originally can not be controlled the AT state of this moment, the ROT value that will cause AN to measure like this is inaccurate, thereby influence the distribution of reverse link resources, can cause periods of network disruption under the serious situation.
