Problems solved by technology

[0005] The small packet detection scheme can achieve the purpose of improving PDCH bearing efficiency by reducing the resource allocation for instant services. However, the small packet detection threshold cannot be flexibly adjusted according to the actual needs of the existing network, which will cause the resource allocation strategy to be unable to adapt to the voice and voice in the existing network.

Embodiment 1

[0056] For multi-carrier devices, the voice and data service traffic data and resource carrying efficiency indicators of each cell are collected by cell. include:

[0057] Collect traffic data in units of 1 hour and save it in the server. The server retains at least one week of traffic data. The traffic data is mainly used to judge and predict the voice service and data service traffic conditions of each cell in the next hour, and provide a basis for the adjustment of the small packet detection threshold.

[0058] Collect the current channel resource configuration and occupancy in a unit of 1 hour: including the number of configurations and occupancy of the traffic channel (TCH) in the cell, the number of configurations and occupancy of static and dynamic PDCH, used to count the number of available PDCH resources.

[0059] At the end of each period, the mapping relationship between the available PDCH resources, the predicted traffic volume of data services, and the packet prediction...

Embodiment 2

[0066] When the current period ends, predict the data traffic and the number of available PDCHs in the next period, and adjust the packet detection threshold in the next period according to the prediction result.

[0067] The first step is to predict the traffic volume: compare the traffic volume of the voice and data services in the previous hour with the corresponding traffic data corresponding to the same period of the day in history. When the two are equal, judge the traffic volume of the next hour. The traffic data is equivalent to the traffic data of the day and one hour in the history, and the strategy analysis is carried out based on the traffic data of the day and the next hour in the history; when there is a difference between the two, according to the difference between the two, through the historical The traffic data of the next hour of the day predicts the traffic data of the next hour and analyzes the strategy accordingly.

[0068] The second step is to count the numb...

Embodiment 3

[0082] After adjusting the small packet detection threshold, the system monitors the network performance based on the collected resource carrying efficiency data with a granularity of 15 minutes. If the resource carrying efficiency is lower than the expected target, the current small packet threshold A~C will be further optimized according to the step length, and then the carrying efficiency statistics will be done after optimization, and the carrying efficiency of the previous statistical cycle will be compared. The specific method is:

[0083] If the optimized carrying efficiency is better than before optimization, you can increase the step size and continue to adjust the small packet detection threshold according to the last adjustment direction; if the optimized carrying efficiency is worse than before optimization, restore the last small packet detection gate Limit.

Abstract

The invention provides a method and device for adjusting a packet detection threshold. The method comprises the steps that the data service telephone traffic and the available PDCH number of the next period are predicted according to historical data, a corresponding relation list of the predicted data service telephone traffic, the available PDCH number and the packet detection threshold in the historical data is searched for, and if a corresponding item is found, the packet detection threshold of the next period is adjusted to be a packet detection threshold of the corresponding item; if the corresponding item is not found, the resource bearing efficiency of the next period is calculated according to the predicted data service telephone traffic and the available PDCH number, and the packet detection threshold of the next period is adjusted according to the relation of the predicted resource bearing efficiency of the next period and the current resource bearing efficiency. According to the method and device, the packet threshold can be flexibly adjusted according to the actual requirements of a current network.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and in particular to a method and device for adjusting the detection threshold of small packets. Background technique [0002] At present, the resource scheduling mechanism of GSM / GPRS network is not perfect, and there is a phenomenon that the proportion of data services is high but the utilization rate is low. Compared with real-time data services, instant messaging services have a limited amount of data transmitted in the same time, but the system does not consider the transmission characteristics of different data services and allocates the same number of packet data channels (PDCH) when allocating resources. As a result, instant messaging services consume a lot of resources, which greatly reduces the carrying efficiency and benefits of data services. [0003] In order to make rational use of resources and improve the efficiency of PDCH utilization, various manufacturers have...
