Abstract:
1. A channel allocation method for use in a telecommunication system, the method comprising: receiving a channel access request to a radio receiving unit from a mobile station of a telecommunication system; performing a preprocessing operation on the channel access request using a predefined configuration of devices and algorithms of the radio receiving unit; computing, during the preprocessing operation, one or more characteristics of the channel access request; filtering background noise from the channel access request; comparing the one or more computed characteristics of the channel access request against corresponding one or more detection rules, wherein each of the detection rules is independent of said configuration of the radio receiving unit; considering the channel access request valid in response to each of the computed characteristics of the channel access request fulfilling the corresponding detection rule; and outputting the channel access request for channel allocation in response to the channel access request being considered valid.
