Patent ID: 8570926

Claim:
A method for inferring a state promotion procedure of a radio resource controller state machine in a network, comprising: setting, via a processor of a user endpoint device, a radio resource control state for the user endpoint device to a first state, wherein the first state is associated with a first level of a radio resource; sending, via the processor, a first number of packets from the user endpoint device to a radio network controller, wherein a size of the first number of packets does not trigger a promotion from a second state to a third state, wherein the second state is associated with a second level of the radio resource, wherein the third state is associated with a third level of the radio resource, wherein the second level of the radio resource is larger than the first level of the radio resource and the third level of the radio resource is larger than the second level of the radio resource; receiving, via the processor, a first set of echoes associated with the first number of packets; sending, via the processor, a second number of packets from the user endpoint device to the radio network controller, wherein a size of the second number of packets triggers a promotion from the second state to the third state; receiving, via the processor, a second set of echoes associated with the second number of packets; determining, via the processor, a round trip transmission time for sending the second number of packets and receiving the second set of echoes; determines, via the processor, if the round trip transmission time is larger than a normal round trip transmission time between the user endpoint device and the radio network controller by a predetermined length of time; inferring, via the processor, that the promotion procedure is a promotion from the first state to the second state and then to the third state, when the round trip transmission time is larger than the normal round trip transmission time between the user endpoint device and the radio network controller by the predetermined length of time; and inferring, via the processor, that the promotion procedure is a promotion from the first state to the third state, when the round trip transmission time is not larger than the normal round trip transmission time between the user endpoint device and the radio network controller by the predetermined length of time.
