Abstract:
1. A method of optimizing radio resources in the UMTS terrestrial radio access network (UTRAN) of a Universal Mobile Telecommunications System (UMTS) network when using a user equipment (UE) to perform internet downloads, comprising: transferring information relating to changes in the radio resources available to web browser application at a user equipment (UE) and/or relating to changes in the radio resource demand of the application, between the application at the UE and a radio resource handling entity of the UTRAN; monitoring anticipated future traffic volume by the web browser at the UE by detecting an outgoing request for data to be downloaded to the UE from a Correspondent Host (CH); sending a request by the web browser application of the UE to the radio resource controller (RRC) of the UTRAN for a switch from a common channel to a dedicated channel allocated to a Radio Access Bearer (RAB) by the UTRAN when the anticipated future traffic volume reaches a predefined level, but prior to that anticipated volume being achieved; receiving the request at the radio resource handling entity; and performing the switch prior to the anticipated volume being achieved.
