A method and arrangement for establishing a packet-switched multimedia session for a mobile terminal connected to a mobile access network. A first Radio Access Bearer RAB is obtained, and the multimedia session is started by communicating media over the first RAB. Simultaneously with the media communication, a quality of communicated media is monitored and evaluated. If the monitored quality is deemed unacceptable, a media-adapted second RAB is obtained, and the session is continued over the second RAB. Thereby, it is not necessary to delay the communication of media by waiting for the second RAB to be obtained.

The invention generally concerns the issue of providing connectivity between two different address realms, generally referred to as an inside realm and an outside realm, by establishing connections through an intermediate gateway. The gateway normally has a number of outside-realm gateway addresses for enabling representation of inside-realm nodes in the outside realm. In a first aspect, support for flexible outside-realm initiated connections is enabled by dynamically establishing new gateway connection states triggered, for each new connection, by a respective user-resource identifier query initiated from a corresponding outside node. In a second aspect of the invention, intelligent use of predetermined connection information in the process of setting up new gateway connection states makes it possible to significantly increase the number of connections that can be simultaneously supported by the gateway using a limited number of outside-realm addresses.

Method and system for enabling connections into networks with local address realms

The present invention relates to arrangements for charging in a packet switched network. Packets are charged differently dependent on which service flow the packets belong to. The charging system comprises a control system and a serving element residing in a packet forwarding system wherein said control system comprises an account function adapted to manage an account of at least one user and a charging policy decision point arranged to calculate a charging policy for allowed services for the at least one user. Moreover, said serving element comprises a token bucket per user adapted to store reservations received from the account function of the user associated with the token bucket and a charging policy enforcement point arranged to perform charging for a plurality of the allowed services by reducing the stored reservation of the token bucket according to the calculated charging policy.

System for providing flexible charging in a network

A method and apparatus for providing selective access to a network, between an end device and a network such as the Internet through one or more access network terminating devices includes determining an access capability for each access network terminating device and comparing the access capability with a preferred access capability associated with a user preference. Best access is determined based on a comparison of the capabilities of the access network terminating devices and the preferred capabilities. Once a match is found, one of the access network terminating devices is selected based on the comparison and the end device is configured according to the access capability of the selected one of the access network terminating devices. Access capabilities include, for example, cost of access, coverage area, and QoS. While communicating with the network the end device continues to detect if new access network terminating devices are available. The access capability for each of the new access network terminating devices is determined and compared with the preferred access capability and/or the current access capabilities being provided to the end device. One of the new access network terminating devices can be selected based on the comparison and the end device configured according the access capability of the new access network terminating device.
