Zusammenfassung:The present invention addresses the issue of receiving a request to install control rules before having received a corresponding QoS Authorization, specially where the QoS Authorization requires a prior reservation of resources. To this end, there is provided a method of pre-authorizing a request for a bearer resource before having received a QoS authorization for said request, and comprising the steps of: receiving a request for a bearer resource; determining that a QoS authorization has not been received yet; pre-authorizing said request for the bearer resource by installing initial control rules; and updating the previously installed initial control rules with final control rules upon receipt of the QoS authorization. This pre-authorization and the submission of initial control rules are carried out from a PCRF server towards a PCEF device, before having received the QoS authorization. In particular, the pre-authorization may be triggered from a P-CSCF at the originating or destination side, or at both.
