Method of controlling radio access bearer setup in a radio network, wherein a set of pre-determined RAB setup criteria are defined, the method comprising the steps of-receiving from a mobile station an Activate PDP Context Request (1) including RAB selection parameter, -evaluating the request from the mobile station (not shown) and if positive send a Create PDP Context Request (4) to a gateway node (GGSN), -evaluating (4B) the response from the gateway (GGSN) and if receiving a positive response, -evaluating (4C) RAB setup criteria for the mobile station, -if at least one RAB setup criteria evaluation is positive performing RAB set-up (5), and-if the RAB setup is successful (5B), transmitting a PDP Context Accept message (9) to the mobile station. Alternatively, the method comprises the steps of-receiving from a mobile station an Activate PDP Context Request (1) including a RAB selection parameter, -evaluating the request from the mobile station (not shown) and if the evaluation is positive sending a Create PDP Context Request (4) to a gateway node (GGSN), -evaluating (4B) the response from the gateway (GGSN) and if receiving a positive a Create PDP Context Response, and-unconditionally transmitting a PDP Context Accept message (9) to the mobile station.
