Abstract  Abstract

If the network pages the mobile station using a temporary mobile user identifier (TMUI), the mobile station sends a response to the network. Thereafter, the network authenticates the user using an encryption key and a random number corresponding to the temporary mobile user identifier (S8 to S10). If the temporary mobile user identifier is authenticated, normal call acceptance procedure is executed. If the mobile station is authenticated even if the temporary mobile user identifier is wrong, the network reassigns a new temporary mobile user identifier to the mobile station and terminates the communication. In communication, the network and the mobile station mutually notify each other of the encryption start time and negotiate with each other about the network encryption method. Diversity handover is also initiated at the call attempt. In addition, if branch switching is needed, the current branch is left with a new branch capable of performing diversity handover. In addition, when a new call is generated to or from a mobile station capable of simultaneously processing a plurality of calls, the mobile station uses the same branch configuration and the same communication frequency band for all calls. In addition, when a new call occurs to a mobile station capable of processing a plurality of calls at the same time or a new call is generated from the mobile station, a branch structure and a communication frequency band capable of continuing all calls are selected and used. Therefore, the mobile communication system is suitable for the transmission of various data according to the development of multimedia.
