Abstract: The embodiments of the present invention provide an interleave-based method and apparatus for enhancing capacity of a random access channel, wherein the method is applied to a terminal device. The method includes: receiving a set of preamble sequences and at least two interleavers sent by a base station; determining, when a random access is triggered, a to-be-used preamble sequence from the set of preamble sequences as a target preamble sequence, and randomly determining a to-be-used interleaver from the at least two interleavers as a target interleaver; performing interleaving processing on the target preamble sequence by using the target interleaver to generate an interleaved target preamble sequence, wherein, performing interleaving processing on the same preamble sequence by using different interleavers will generate different interleaved preamble sequences; sending a random access request to the base station by using the interleaved target preamble sequence. Applying the embodiments of the present invention can increase the number of available preamble sequences and increase the capacity of the PRACH.

Abstract: A method and system for monitoring and processing a wireless signal are described. The method includes, if an authorized base station/Access Point (AP) receives a first abnormal signal from the terminal, which is identified as an unauthorized signal by a terminal, processing, by the authorized base station/AP, the first abnormal signal. If the authorized base station/Access Point (AP) receives a second abnormal signal from the terminal and the terminal cannot determine whether the second abnormal signal is the unauthorized signal or an authorized signal, identifying, by the authorized base station/AP, characteristics of the second signal and processing the second abnormal signal if the second abnormal signal is the unauthorized signal.

Abstract: In a monitoring region including multiple cells, UE reports KPI parameters and location information to an eNodeB when triggering an A3 event representing that QoS of a neighboring cell is better than a predefined offset of a serving cell. The eNodeB reports the KPI parameters and the location information to an OAM device in each monitoring cycle. The OAM device classifies UEs according to the KPI parameters and a cluster analysis method, and determines according to a cluster analysis result whether there is a disconnected cell in the monitoring region; when determining that there is a disconnected cell in the monitoring region, counts the number of disconnected cells, determines disconnection types of the disconnected cells, locates the disconnected cells according to the location information of the UEs in the SON, and triggers a compensation measurement for each disconnected cell according to the disconnection type of the disconnected cell.
