    Abstract: PROBLEM TO BE SOLVED: To improve communication quality by providing a hard succession configuration in which the interruption of connection to a mobile object is small/short regarding a general mobile telephone system (UMTS) operating on the basis of a packet exchange theory, an overall system (GSM) for mobile communication or the other remote mobile radio communication system. SOLUTION: In this packet exchange remote mobile radio communication system such as the UMTS or the GSM, a target RNC 24 requests a direct link 36 to an operating controller 22 for in hard handover about a mobile object 18, the controller 22 transmits an uplink frame from the mobile object 18 to both a TRNC 24 and a core network 10, the network 10 transmits a downlink frame to the TRNC 24. The TRNC decides the time when the handover is completed and reconstructs a frame when necessary.

    Abstract: PROBLEM TO BE SOLVED: To provide enhancement of a configuration for a call from one mobile body to another in a mobile wireless remote communication system such as a generic mobile phone system (UMTS) or a blanket system (GSM) for mobile communication. SOLUTION: An RNC 22 transmits information with respect to a 1st mobile body such as an IMSI of the 1st mobile body from the 1st mobile body 18 to a CN 10 through an uplink with respect to two mobile bodies 18, 19, the both of which are placed in the same UTRAN 24 and at least either of which has the IMSI, stores at least part of the information, and when the RCN 22 receives the same information from the CN 10 toward the 2nd mobile body through a downlink, the RNC 22 recognizes that the two mobile bodies are present in the same UTRAN 14 and starts local switching operation in this method. A delay can be reduced and switching of the call is attained on a local reference. The RNC 22 may store a data frame from the 1st mobile body 18 for the comparison in place of storing the IMSI.

    Abstract: In a call between mobiles 18, 19 located in the same UTRAN 24, and in which at least one mobile has an IMSI, a method of providing local switching in which the RNC 22 sends on an uplink from the first mobile 18 to the CN 10 information related to the first mobile, such as its IMSI, and stores at least a part of that information; when the RNC 22 receives the same information on a downlink from the CN 10 to the second mobile 19, it recognizes that the mobiles are within the same UTRAN 14 and performs local switching. Delay is reduced and the call can be charged at local rates. Instead of the IMSI, data frames from the first mobile 18 can be stored by the RNC 22 for comparison.
