TL;DR: In this paper, the authors defined a 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 (GG SN and if receiving a positive response,

Abstract: 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.
