Problems solved by technology

Inability to operate in accordance with protocol, which in turn affects the quality and reliability of communications with the erroneously operating mobile station, and thus interferes with users using the mobile station and / or users of adjacent mobile stations
Also, wireless systems are burdened by having to manage mishandling mobile stations, which reduces the system's effectiveness in providing reliable service to all users

Embodiment Construction

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0013] In some cases the mobile station may not be able to communicate according to the protocol or standard, thus the erroneous operation is enumerated below. A mobile station may violate the standard for which it was designed, for example by performing a chaotic registration and not following the rules set forth in the standard. While this may mean that the mobile station cannot register so that it may be declared fraudulent (this is not necessarily the case), and it is assumed to have done enough of the registration part correctly to carry a high probability of It is possible to confirm that the mobile station is really the identified mobile station, but that mobile station is misoperating. The mobile station may also repeatedly fail to perform to the required standard. For example, a mobile station may exhibit a persistently high bit error rate (BER) / frame erasure rate (FER) over a period of time, and in the case ...

Abstract

Malfunctioning or misbehaving mobile stations (12), that are capable nonetheless of continuing to communicate with a wireless communication system (10), are detected for the purposes of either shutting down misbehaving mobile stations or reporting misbehaving mobile stations so that corrective action can be taken. An error detector and interpreter (23) detect (42) in wireless communication signals received from a mobile station any breach of protocol errors indicative of faulty operation of the mobile station. A misbehavior analyzer (26) analyzes (44) the errors over time to determine whether the mobile station is misbehaving. Normal access of the mobile station to the wireless communication system is shut down (46) or a message is sent to the subscriber in the event the mobile station is determined to be misbehaving. The mobile station also has a shutdown mode of operation (36), controllable by a message sent from the network, in which the mobile station remains idle and nonfunctional until repaired. The quality of service to subscribers using the wireless communication system is thus improved.

Description

field of invention [0001] The present invention relates to a wireless communication system capable of detecting erroneously or abnormally operating mobile stations. The present invention also relates to a mobile station with a remotely activated shutdown mechanism for remote shutdown when erroneous operation is detected. Background of the invention [0002] In the case of a wireless communication field where a mobile station accesses a wireless system comprising one or more base stations and a cellular phone in which a series of base stations are arranged in a cell, switching off or ending communication with a given mobile station when the signal strength becomes too weak Wireless communications of stations are known. This routine is part of controlling the wireless communications in the system. It is also known to provide an automatic shutdown of communications with a mobile station as a security feature when the authenticity of the mobile station's identification respons...
