The invention relates to a method and a system for IP-based telephony and video conferencing between at least one IP node () and a second terminal (). According to said method, authentication data is transmitted from an identification module () of the IP nodes () and registration data is transmitted to a registration module (). The IP node () is authenticated using an authentication module () and a home location registry (). Corresponding location data is stored in the location database and is forwarded to the identification module () of the IP node (). Said IP node () is then released for IP based telephony or video telephony.

Access method in a WLAN for an IP mobile telephone with authentication by means of an HLR

A method for setting up a data link including requesting an identity of an IP network node by a registration module, transmitting an International Mobile Subscriber Identity (IMSI) stored on a Subscriber Identity Module (SIM) card of the IP network node to the registration module, storing the received IMSI in a user database of the registration module, complementing an IP data channel to form signal and data channels of a GSM network by a signaling gateway module, using the complemented IP data channel as a basis for generating the necessary SS7/MAP functions for authenticating the IP network node, authenticating the IP network node by using the IMSI of the SIM card of the IP network node, receiving an entry in the user database of the registration module upon successful authentication, and setting up a data link to at least some of the network nodes.

Switching system and corresponding method for unicast or multicast end-to-end data and/or multimedia stream transmissions between network nodes

A method for setting up a data link including the steps of requesting an identity of an IP network node by a registration module; transmitting an International Mobile Subscriber Identity (IMSI) stored on a Subscriber Identity Module (SIM) card of the IP network node to the registration module, storing the received IMSI in a user database of the registration module, complementing an IP data channel to form signal and data channels of a GSM network by a signaling gateway module, using the complemented IP data channel having GSM data as a basis for generating the necessary SS7/MAP functions for authenticating the IP network node, authenticating the IP network node by using the IMSI of the SIM card of the IP network node, receiving an appropriate entry in the user database of the registration module upon successful authentication, and setting up a data link to the at least some of the network nodes by the control module of the central connecting unit.

A method and system for content-based billing in IP-networks, carry out and transmit to a control gateway module the authentication and/or service authorization of an IP-node based on the IMSI of the SIM card of the node for HLR and/or VLR of a GSM network and guide the access of the IP node to the content of a network content provider through said control gateway module, control involved costs by means of the nodule on the base of the access target address, detect call detail records according to the IP-node services by a core engine module, detect at least the identity of the IP-node and/or the time and/or a provider of the required services by means of the call detail records during access to the control gateway module, transmit the data to the billing module and compute call detail records and/or clearing data based thereon and/or TAP files through the billing system of a service provider or a financial institution. The disclosure relates, in particular to the mobile IP nodes in heterogeneous networks.

Method and system for content-based billing in IP networks

The invention relates to a method for automatic roaming between heterogeneous WLANs and/or GSM/GPRS/UMTS networks, in which method, for authentication, a mobile IP node () requests access to the WLAN at an access point (), in which method, upon request from the access server (), the mobile IP node () transmits an IMSI stored on a SIM card () of the mobile IP node () to the access server (), and in which method, based on the IMSI, using information stored in an SIM user database (), the logic IP data channel of the WLAN is supplemented user-specifically towards corresponding GSM data for signal and data channels of a GSM network, and the authentication of the IP nodes () is carried out in an HLR () and/or VLR () of a GSM network.

Method and system for GSM authentication during WLAN roaming

The invention relates to a method and system for recording and billing of services during roaming of a mobile IP node () in heterogeneous WLANs, in which first call detail records are transmitted from an access server () to a billing module () and second call detail records from the access server to a proxy module (). By means of a clearing module (), the obtained service is billed () at a provider () of a fixed network () and/or TAP files () are transmitted to a GSM () service provider () for billing.
