Embodiment

[0026] A GPRS network access optimization method for power distribution communication. The GPRS network system uses the S-ALOHA method for random access, and the user sends a random access application on the random access channel. It is characterized in that the network side passes the statistical The state of the random access channel, the statistics of the success probability of the user on the access network side sending the access application, the idle probability and the busy time probability of the random access channel, to estimate the load of the current random access channel, and thus calculate the user initiated access In order to achieve the purpose of optimizing the random access process of the GPRS network.

[0027] The optimization method specifically includes the following steps:

[0028] Step 1: The base station monitors the state of the random access channel in each monitoring period, and the probability of the channel being idle and the probability that the...

Abstract

The invention relates to a GPRS (General Packet Radio Service) network access optimization method for power distribution communication. Random access is performed on the GPRS in a network system S-ALOHA manner, a user sends a random access application on a random access channel, and a network side calculates the probability of success of sending the access application by the user at the network side and the idle probability and busy probability of the random access channel by calculating the state of the random access channel so as to estimate the load of the current random access channel, so that the optimization probability of the access application sent by the user is calculated, and the random access process of GPRS network is optimized. Compared with the prior art, the problem of low network random access efficiency under the condition of high load can be solved, and the control of terminal access is realized through a simple and feasible adjusting mechanism.

Description

technical field [0001] The invention relates to a GPRS network access method, in particular to a GPRS network access optimization method for power distribution communication. Background technique [0002] Smart grid is the latest trend in the development and transformation of power systems in the world today. It targets power systems in various links including power generation, transmission, transformation, distribution, use and dispatching, and continuously develops and applies new control technologies, information technologies and management technologies. Realize the intelligent exchange of information. As a public platform and an important means to support the construction of smart grid, the communication information system runs through the six major application links and is the basis for the implementation of distribution network automation. Stable and reliable communication is inseparable from the even and fast transmission of data and commands. system for support. ...
