The invention related to method for providing connection security for the transmission between communicating parties in a telecommunication network, the method comprising the steps of: exchanging security parameters between communicating parties, providing connection security for messages based on these security parameters, and transmitting said messages between communicating parties. It is characteristic for the method according to the invention that it further comprises the steps of: reaching agreement between communicating parties on an interval for recalculation of the security parameters, monitoring of the interval for recalculation by the communicating parties, recalculating the security parameters at the agreed interval, and providing connection security for messages based on the latest recalculated security parameters.

Security method for transmissions in telecommunication networks

A method and system for revenue sharing between mobile operators and content providers. The content providers, through a data network, provide data services to the end users of the mobile operators. For the data services, the content providers are paid by the mobile operators based on the revenue collected by the mobile operators from the end users using the services. An intermediate proxy is disposed between a mobile operator and the data network to keep track of the data amount transmitted by the content providers and the users and to keep track of the revenue sharing agreements established between that mobile operator and the content providers. Additionally, an intermediate proxy is linked to each content provider to keep track of the data amount transmitted to the end users via a mobile operator and to keep track of the revenue sharing agreement with that mobile operator.

Method and system for sharing transmission revenue between mobile operators and content providers

In a method for multicasting in a radio network, having at least one base station and multiple mobile terminals, the broadcast message is broadcast from the base station, and the broadcast message is received at the mobile terminals. Furthermore, a broadcast message is formulated as a multicast message, and a token is delivered to a selected group of mobile terminals. The token is needed to recover the information of the multicast message. The selected group of mobile terminals includes at least two mobile terminals. The token is used by the selected group of mobile terminals to allow the reception and recovery of the multicast message.

Implementation of multicast messaging in a mobile telecommunications network

The invention relates to a method of providing connection security for a connection between terminals in a wireless network. In the method data is transmitted from a first terminal (MS1) via nodes in the network to a second terminal (MS2). The method according to the invention is characterized by that it includes the steps of: routing the transmitted data via a mediator (MD), using the first security method for providing connection security at the security protocol layer between the first terminal (MS1) and the mediator (MD), using the second security method for providing connection security at the security protocol layer between the mediator (MD) and the second terminal (MS2), and performing the security method conversion at the security protocol layer at the mediator (MD).
