A method of providing telecommunication services in a telecommunication system including a terminal, a serving network providing the terminal with services, and a bearer network in functional connection with the serving network. One or more databases including subscriber data are created in the telecommunication system, the subscriber database(s) being in functional connection with the bearer network. Data according to the subscriber database, such as a subscriber identifier, are transmitted to the serving network and/or the terminal. The terminal is provided with services in accordance with the transmitted subscriber data.

Utilization of subscriber data in a telecommunication system

A method of arranging data protection in a telecommunication system including a first mobile communication network, a second mobile communication network, and a mobile station supporting both of the mobile communication networks is disclosed. The method includes ciphering traffic between the mobile station and the first mobile communication network using a first cipher key; calculating a second cipher key to be used for ciphering traffic between the mobile station and the second mobile communication network in the first mobile communication network when the mobile station operates in the first mobile communication network; transmitting information necessary for calculating the second cipher key from the first mobile communication network to the mobile station when the mobile station operates in the first mobile communication network; and calculating the second cipher key at the mobile station to be used for ciphering traffic between the mobile station and the second mobile communication network.

Arranging authentication and ciphering in mobile communication system

A method and system of offering wireless telecommunication services in a visited telecommunication network for a terminal device which does not have a first identifier accepted by the network. In the method, the visited network gives the terminal device a right to a temporary use of a telecommunication connection and establishes a connection with a third party in order to obtain a confirmation of paid services, for example. The third party checks a second identifier transmitted by the terminal device and transmits the confirmation to the visited network, which offers telecommunication services for the terminal device.

Disclosed is a method for performing an inter-system handover. The method triggers the handover of a mobile station ( ) from a UTRAN system to a GSM system by sending a HANDOVER FROM UTRAN COMMAND message from the UTRAN system. For the case where a HANDOVER COMMAND is sent transparently with the HANDOVER FROM UTRAN COMMAND, where the HANDOVER COMMAND has an information element set for indicating that ciphering is to be started, the method begins data ciphering immediately after handing over to the GSM system such that the first data frame transmitted by the mobile station in the GSM system is a ciphered data frame. For the case where there is a pre-existing UTRAN system ciphered data connection when the HANDOVER FROM UTRAN COMMAND message is received, the method continues without interruption the use of data ciphering with the data connection after handing over to the GSM system.

A method, a system, or an article of manufacture provides Mobility Management (MM), for example, an update procedure, in a Core Network (CN) of a mobile communication system. The Mobile Station (MS) includes an indicator which defines an update type. The update type includes: all CN entities; one type of CN entity only. If the indicator has the update type of all CN entities, the MS registers all CN entities. If the indicator has the update type of one type of CN entity only, the MS registers the one type of CN entity only. The CN entities may be MSC/NVLR CN entity, SGSN CN entity, or other CN entity. The method includes the MS determining to which of the CN entity to perform the update procedure; the MS updating the CN entity; the CN acknowledging the MS whether update is successful or failed; and the CN acknowledging the MS whether update of other CN entity is needed, if needed, the CN defining to which of the CN entity to perform update, and continuing the update of the defined CN entity. The MS does not have to know the services subscribed to a user, nor does the MS have to know the configuration of the CN.

A cellular radio access network and a location updating in a cordless communications system, in a cellular radio access network ( ), which is connected to one or more core networks ( ) or services (SP to SP ), each of them having a dedicated mobility management. In a cell, identities of all those location areas are broadcast to which said cell belongs. A subscriber terminal (MS) sends to the radio access network only one location updating message irrespective of how many core networks ( ) or services (SP to SP ) have a simultaneously changing location area at a handover from one cell to another. On the basis of the information contained in the location updating message, the network ( ) defines the core networks or services and location areas to which the location updating applies and sends a location updating message informing the new location of the subscriber or the subscriber terminal separately to each defined core network or service.
