摘要： Herein provided is a method for operating a base station of a cellular network. The base station serves user equipment camping thereon, or connected thereto, and agrees with the user equipment to a periodic dedicated prescheduled uplink transmission schedule. Upon determining that an uplink occasion of that schedule is missed by the user equipment, the user equipment is considered as unavailable for communicating at said uplink occasion in relation with the base station. If it is considered unavailable, it instead maintains a presently active dedicated prescheduled uplink transmission schedule. Otherwise it cancels the presently active dedicated prescheduled uplink transmission schedule. Other embodiments are disclosed.

摘要： A method for a user equipment operating in a cellular network having a plurality of base stations, the user equipment operating on at least one of the base stations, hereinafter the serving base station, for the case of a communication loss to its serving base station, whereby the conditions relating to the serving base station or the corresponding frequency fulfills the criteria concerning jamming. The method includes the steps of: scanning for accessible base stations of the cellular network, examining the at least one base station being identified through the scanning step, by means of signalling message, evaluating the response behavior of the at least one base station, wherein in consideration of the response behavior of at least one of said base station if said base station is rated as suspicious: indicating a jamming situation, otherwise camping on at least one of the base stations.
