Abstract: A communication method for use in a communications system includes at least one user. The method includes a step of establishing a session for permitting a user to communicate with at least one entity. The method also includes the steps of using a first charging method for one part of the session and using a second charging method for a different part of the session.

Abstract: A method and apparatus for charging against prepaid credit in a communication network. When a first terminal requests establishment of a call to a second terminal, the network ascertains whether prepaid credit is involved. If so, accounting sessions are established between an accounting server and any accounting servers that will raise costs during the call. A session identifier is generated. Once the call is established, charging update data is sent from the accounting clients to the accounting server, where it is collated on the basis of the accounting session identifier, whereby enabling updating of the prepaid credit during the call.

Abstract: There is disclosed a method for charging for services in an IP based communication system, comprising: establishing an accounting session between a network element and a charging function for the session; and initiating a change in the accounting session at the charging function.

Abstract: A method for charging in a communication system is described. The method comprises initiating provision of a service for at least two parties. Further, it is verified that each of the parties is capable of paying for the use of the service. Then, payment information is generated and use of the service is charged based on the payment information. The service may be a game. A communication system configured to provide and charge the service is also disclosed.

Abstract: A method for charging for services in a communication system comprises a charging entity. The method comprises a step of sending a first message to the charging entity. The method also comprises a step of generating a charging identity at the charging entity if it is determined that the first message does not include a charging identity.

Abstract: A system and method of monitoring number portability in a communication system, comprising transmitting ported-out information to a network element are disclosed. The system includes an originating network and a recipient network. The originating network includes a first network element for establishing a call to a ported-out subscriber and for transmitting ported-out information.

Abstract: There is disclosed a method for charging for services in a communication system supporting a Diameter IP protocol, comprising defining at least one attribute value pair to define sponsorship information.

Abstract: This invention relates to a method for providing accounting requests, where an accounting request comprises at least one identifier and relates to a service provided to a user of a communication network. In the method a first accounting request is transmitted and a second accounting request corresponding to the first accounting request is prepared. The second accounting request comprises at least one of the at least one identifier in the first accounting request as correlation information. The second accounting request is transmitted as a retransmitted first accounting request, if it is determined that retransmission of the first accounting request is required.

Abstract: A method for charging for services in a communication system comprises a charging entity. The method comprises a step of sending a first message to the charging entity. The method also comprises a step of generating a charging identity at the charging entity if it is determined that the first message does not include a charging identity.
