Problems solved by technology

[0012] (1) The model characteristics of the Irish C algorithm are significantly different from those of the GPRS / EDGE system model: that is, the Irish C algorithm is based on "queuing and waiting", while the GPRS / EDGE system is based on "channel sharing", so the current The number of required PDCH configurations is not accurate enough
[0013] (2) Since the determined number of currently required PDCH configurations is not accurate enough, it is necessary for the optimization personnel to determine the final PDCH configuration strategy based on the other comprehensive considerations mentioned above. Therefore, the empirical adjustment method is emphasized, and the theoretical basis is insufficient. High expectations
Due to the defects of the core algorithm itself, the influence of other comprehensive considerations is increased. Therefore, the optimization personnel need to have rich on-site experience to obtain a more reasonable configuration result, that is, the subjective factors of the adjustment result are greatly affected, and the reliability cannot be guaranteed.
[0014] (3) It is not suitable for large-scale planning and adjustment, and the efficiency is reduced. The larger the data volume, the harder it is to guarantee the accuracy
The larger the adjustment area, the higher the complexity and the more comprehensive considerations. Therefore, the number and difficulty of artificial adjustment by the optimizer will increase, which will directly lead to the decline of work efficiency and quality.

Embodiment 1

[0071] Embodiment 1 of the present invention provides a method for configuring PDCHs in a cell based on the method for determining the number of PDCH configurations currently required by the above-mentioned cell. The flow chart of the method is shown in Figure 3, including:

[0072] Step S301, determine the cell that needs to be configured with PDCH. This step can use various methods in the prior art, for example: determine the cell with the average multiplexing degree of PDCH greater than the threshold value as the cell that needs to be configured with PDCH. Limits can be set at 1.2-1.5.

[0073] Step S302, determine the current voice traffic channel TCH configuration number TCH of the cell 当前配置 and the current PDCH configuration number PDCH 当前配置 ; and also determine the current required TCH configuration number TCH of the cell 当前所需 , various methods in the prior art can be used specifically, for example, the Irish B algorithm is used to determine TCH 当前所需 , at this time, ...

Embodiment 2

[0081] Embodiment 2 of the present invention provides a method for configuring PDCHs in a cell based on the method for determining the number of PDCH configurations currently required by the above-mentioned cell. The flow chart of the method is shown in Figure 4, including:

[0082] Step S401 is the same as the above step S301.

[0083] Step S402 is the same as the above step S302.

[0084]Step S403 is the same as the above step S303.

[0085] Step S404, judging whether the second difference is greater than the PDCH adjustment threshold, if so, proceed to step S405; otherwise, proceed to step S406. Wherein, the PDCH adjustment threshold can be set according to actual needs and experience, for example, preferably, it can be set to 2.

[0086] Step S405, determine whether to allow the opening of a new voice half-rate channel for sharing voice services. For key protection cells and traffic hotspot cells, in order to reduce the impact on user perception, it is generally not reco...

Abstract

The invention discloses a packet data channel configuring method and device. The packet data channel configuring method comprises the following steps of: acquiring the current data quantity of a cell which needs to carry out PDCH (Packet Data Channel) configuration; determining the PDCH configuration number which is currently needed by the cell according to the acquired current data quantity and set service quality conditions, wherein the set service quality conditions represent the requirements for data transmission rate of the cell; and carrying out the PDCH configuration on the cell according to the determined currently-needed PDCH configuration number. Compared with the prior art, the packet data channel configuring method and device can be used for enhancing the determining accuracy of the PDCH configuration number currently needed by the cell, thereby enhancing the accuracy and the effectiveness of the PDCH configuration carried out on the cell.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for configuring a packet data channel PDCH. Background technique [0002] With the rapid development of business volume and network scale, how to rationally allocate the carrier frequency resources of the existing network to the maximum extent while taking into account the wireless utilization rate and customer perception has become an important issue to solve the contradiction between capacity and resources. As the most important business growth point, data services show a trend of rapid growth under the background of comprehensive tariff reductions. How to reasonably configure data service channels to ensure data service needs and customer perception is particularly important. [0003] The configuration of GPRS / EDGE network resources will directly affect the quality of GPRS / EDGE network, and the quality of the configuration determines the average throughp...
