Disclosed is a method and system for performing a Serving Radio Network Subsystem ('SRNS') Relocation for a given User Equipment ('UE') in a Universal Mobile Telecommunications System (&#x201c;UMTS&#x201d;) network between a UMTS radio network and a UMTS core network, in which the UMTS radio network and the UMTS core network are logically separated, the method comprising: sending a Relocation Required message from the serving Radio Network Controller (&#x201c;RNC&#x201d;) to the core network; and sending a Relocation Request message from the core network to the Target RNC.

SRNS relocation in a UMTS network

A method of performing a SRNS Relocation in a UMTS network for a given UE, the method comprising sending a Relocation Required message from the serving RNC to the core network and sending a Relocation Request message from the core network to the target RNC, the Relocation Required message containing a RRC Initialisation Information container which is incorporated transparently by the core network into the Relocation Request message, and the RRC Initialisation Information container in turn containing information enabling a mapping to be made between RABs and RBs for the UE.

A method of charging at a mobile switching centre, MSC ( ) of a mobile telecommunications network ( ) in respect of a call initiated by a mobile terminal ( ) registered with the network ( ) and terminating outside of the network. At the MSC ( ) the call is classified, according to the associated A-number and/or the B-number, as corresponding either to a call for which the MSC ( ) is to be the charge determination point or to a call for which the charge determination point is located outside of the mobile telecommunications network ( ). In the event that the call belongs to the latter class, the MSC ( ) receives tariff information from the external charge determination point ( ) and calculates charge information on the basis of the received tariff information. In the event that the call belongs to the former class, the MSC ( ) disregards any tariff information received from an external charge determination point and calculates charge information on the basis of the mobile telecommunications network's own tariff information.
