Embodiment Construction

[0055] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0056] Reference figure 1 , figure 1 It is a schematic flowchart of an embodiment of a method for filtering false channel requests according to the present invention.

[0057] The method for filtering false channel requests provided by the embodiment of the present invention includes:

[0058] Step S10: Compare the current channel request with the received channel request, and determine whether the current channel request and the received channel request meet the preset initial false channel request filter condition; if the current channel request and the received channel request meet Part of the initial false channel request filtering conditions, execute step S20;

[0059] Step S20: Adjust the false channel request filter condition according to the current channel request and the received channel request;

[0060] Step ...

Abstract

The invention discloses a false channel request filtering method which includes comparing current channel requests and received channel requests to judge whether the current channel requests and the received channel requests meet preset initial false channel request filtering conditions; adjusting the false channel request filtering conditions according to the current channel requests and the received channel requests if the current channel requests and the received channel requests meet a part of the preset initial false channel request filtering conditions; filtering the current channel requests and the received channel requests according to the adjusted false channel request filtering conditions. A corresponding device is further disclosed. By means of the method and device, the filtering conditions are dynamically adjusted according to the false channel request change characteristics, a timely ideal filtering effect is achieved, the network wireless resource utilization rate is improved, and the problem that normal business cannot be conducted due to false channel requests is solved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for filtering false channel requests. Background technique [0002] When a terminal accesses the network in the GSM system, it first reports a channel request message to request wireless resources for access interaction. The channel request is the first step for the terminal to access the network for any service, and is an uplink message. Due to the complexity of the wireless environment and the emergence of various wireless communication devices, the interference to the uplink in wireless communication is increasing, and the impact is increasing. One of them is the creation of false channel requests. The channel request belongs to the access burst. The access buffer bit of this access burst is relatively long, usually 68.25 bits, and carries less information. Therefore, many uplink interference signals are easily decoded into channel request message...
