Problems solved by technology

The disadvantage of this method is that it cannot change with the load level of the network and the level of channel interference. For example, in order to avoid co-channel interference caused by setting the initial transmission power too high, the RNC will set a relatively low value in the system information 7 The initial transmission power calculation parameter, UE uses this parameter to calculate the initial transmission power, if the UE is far away from the base station at this time, then the UE uses this initial transmission power to send the preamble, causing the base station to not receive this pulse and cannot respond , and then the UE will continue to increase the initial transmission power until it successfully sends the preamble, and the process of increasing the initial transmission power will cause interference to its neighboring mobile stations and base stations

Embodiment Construction

[0058] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0059] At first the concept used in the present invention is briefly introduced:

[0060] (1) Range R: The maximum difference of values ​​in a set of data, R=Max-Min, that is, the maximum value-minimum value, which can be used to evaluate the degree of dispersion of the set of data.

[0061] (2) Standard Deviation (Standard Deviation): The average of the distance (from the mean) of each data deviation from the mean, which is the square root of the square of the deviation and the average, and is represented by σ. Therefore, the standard deviation is also a kind of mean, the formula:

[0062] σ = 1 n Σ i = 1 n ( x ...

Abstract

The invention relates to a method for realizing a rapid and random switching-in process in a wireless honeycomb network, comprising the following steps of: statistically storing, analyzing and processing the parameter of system information 7, and processing fast random access process. The method particularly comprises the steps of: reading information of the stored parameter of the system information, analyzing and acquiring a stable time interval part and judging whether the current random switching-in time is in the stable time interval part; extracting the parameter of the current random switching-in time from the stable time interval part or through establishing the BCCH channel receiving system information 7 according to the result; and performing the random switching-in process according to the current random switching-in time. Adopting the method for realizing the rapid and random switching-in process in the wireless honeycomb network, the random switching-in transmission is immediately performed according to the random switching-in parameter foreknown in advance, system delay caused by establishing BCCH channel receiving system information 7 is eliminated; and the method greatly improves user experience, and has the advantages of simple and convenient operation process, stable and reliable working performance and wide application range.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to the technical field of wireless cellular network access, and specifically refers to a method for realizing a fast random access procedure (RACH procedure) in a wireless cellular network. Background technique [0002] In the UMTS wireless communication system, in order for the mobile station to obtain the services of the communication network, such as making a call or transmitting data, it must establish an RRC connection from the mobile station to the base station controller, and the establishment of the RRC connection is realized by the random access mechanism , so the random access process is very important, and it is a bridge for the mobile station to enter the connected state from the idle state. In other cases, the mobile station performs cell reselection in the IDLE state and the CELL_PCH and URA_PCH connection states, and also performs cell update through the ra...
