A method is described for operating a mobile station with a wireless network having packet data capabilities, as is a network that operates in accordance with the method. The method includes establishing default operational parameters values for the mobile station and, when establishing a PDP Context for use by an application, such as a delay-critical application that may be a real-time application (or any application that requires specific operational values, such as DRX values), requesting a modification of the default operational parameters values so as to reduce the delay in the establishment of a TBF for the application. In the preferred embodiment the operational parameters comprise DRX parameters selected to optimize the paging operation of the MS to reduce the delay in transferring packet data to or from the MS. In other embodiments the operational parameters can include MS Radio Access Capability (RAC) parameters, such as Multi-slot Class, GPRS Timers and/or MS Power Class. In one embodiment, requesting a modification includes sending a PDP Context-related message from the mobile station to the network with an information element that specifies values for parameters of the DRX mode, where the values comprise a Split_PG_Cycle code and a non-DRX timer. In this case the PDP Context-related messages comprise one of an Activate PDP Context request, an Activate Secondary PDP Context request and a Modify PDP Context request. The method further includes, when terminating the PDP Context, requesting a modification of the paging parameters values so as to have the default or other parameters values. Preferably, when terminating the PDP Context the mobile station sends a Deactivate PDP Context request message with the information element that specifies the default values for the parameters of the DRX mode.
