Abstract: Social networking services, such as Facebook, Twitter, MySpace and Orkut, are changing our communication habits by introducing new tools that simplify and increase on-line interaction. The exemplary embodiments present methods for measuring the social strength among contacts on the basis of users' on-line interactions, which may be significantly used in real-time collaborative task management (e.g., inviting contacts for collaboration, selecting suitable tools for communication, prioritizing information flow). Moreover, exemplary embodiments provide a framework for developing new mobile social networking applications (social search client, smart dialer or contact applications) by extending the use of social ranking of contacts.

Abstract: A method and arrangement for dynamically adapting thresholds used for selecting a codec mode to be used is presented. Thresholds are adapted in response to the current received signal quality. An estimate of actual prevailing received signal quality is obtained on which the adaptation is based. The present invention can be applied either on the mobile terminal side or on the network side, working on the uplink and/or the downlink. The thresholds can be modified on the receiving side, or, when operating in the network and working on the downlink, the threshold adaptation can be initiated in the terminal.
