Patent ID: 8446832

Claim:
A computer-controlled method of dynamically controlling throughput over an air interface between a mobile terminal and a radio telecommunication system, wherein the radio telecommunication system includes a radio access network and a core network, the method comprising the steps of: determining by a core network node, whether there is a delay-sensitive traffic flow for the mobile terminal; when there is no delay-sensitive traffic flow for the mobile terminal, maintaining a radio access bearer (RAB) for the mobile terminal in a throughput-oriented mode; and when there is a delay-sensitive traffic flow for the mobile terminal, changing a target delay parameter to a lower value to establish a low-delay RAB for the mobile terminal, wherein the step of changing the target delay parameter includes the steps of: determining by a Gateway GPRS Support Node (GGSN), whether a secondary RAB is allowed for the mobile terminal; when the secondary RAB is not allowed, changing the target delay parameter associated with a primary RAB for the mobile terminal to modify the primary RAB to handle the delay-sensitive traffic; and when the secondary RAB is allowed, utilizing a low-delay target delay parameter associated with the secondary RAB to handle the delay-sensitive traffic, wherein the step of utilizing a low-delay target delay parameter includes the steps of: determining by the GGSN, whether the secondary RAB has already been created; when the secondary RAB has already been created, updating a traffic flow template (TFT) associated with the secondary RAB to handle the new delay-sensitive flow; and when the secondary RAB has not already been created, creating the secondary RAB with a low-delay target delay parameter to handle the delay-sensitive traffic.
