A service progress method in a weak electric field in which a jammer is strong in a cellular terminal apparatus

摘要

1. The technical field to which the invention described in the claims belongs;Thereby allowing the cellular terminal apparatus to perform service in a weak electric field having a strong jammer.;2. Technical challenges to be solved by the invention;It prevents a communication channel from erroneously recognizing a strong channel temporarily due to an external influence such as a fading phenomenon during a data transmission / reception in a mobile station, thereby causing transmission / reception data error.;3. The point of the solution of the invention;The ETACS type cellular phone extracts two or more paging channel signals in strong order and tunes them sequentially so that the overhead message train can be completely received within the set time, thereby transmitting and receiving in weak electric field of the receiving channel by jamming propagation,;4. Important Uses of the Invention;The present invention is applied to an ETACS cellular mobile communication system.
