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 a mobile wireless remote communication system such as a generic mobile phone system or a generic system for mobile communication and, specifically, a system that provides a real time service. SOLUTION: In the mobile wireless network such as a generic mobile phone system, when an object RNC 24 takes over control of a mobile object from an RNC 22 handling the control or in the case of relocation, a TRNC 24 transmits a request to an SRNC 22 via an Iur link 27 and the SRNC 22 returns frame timing information. The TRNC 24 synchronizes a user as to an uplink thereby allowing two controllers to transmits the same packet ion a synchronous state. A core network (10) can suppress duplication in a packet.

Abstract: PROBLEM TO BE SOLVED: To provide a mobile wireless remote communication system such as a generic mobile phone system or a blanket mobile communication. SOLUTION: A TRNC 54 in a UMTS directly transmits a takeover instruction signal to an SRNC 52 via an Iur link 50 to realize takeover of control of a mobile body from the RNC 52 handling the mobile body to an object RNC 54. Even when a link is present in advance or not present, the TRNC may transmit a request and a protocol to set the link stated above. A core network no longer takes participation in the takeover and a considerable time can be saved.

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: PROBLEM TO BE SOLVED: To obtain an enhanced mobile body cell reception scenario for a service dependent direct retrial. SOLUTION: The method is a method that establishes transmission to a mobile station in a cellular radio communication system. This method has a step where an exchange receives a signal to start a call and informs a network about a paging message and a step where the paging message is supplied to the mobile station. The display of a radio service request condition is served together with the paging message. Thus, it is required to measure only a cell satisfying a radio service request condition to decide which cell is to be used.

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.

Abstract: A method of use of a UMTS telecommunications network, comprising utilising UMTS signalling to indicate changes in an IP sub-network. To register a Mobile Terminal (MT) or to update its location within the network, signalling relevant to the IP domain is transmitted with UMTS signalling in an integrated approach. This reduces the number of signalling messages that are required and minimises delays.
