Method, network device, computer program and commuter program product for determining power state parameters
First Claim
1. A method, performed by a network device, for determining a set of power state parameters at least partly defining when a wireless terminal is to be in an active state or a power saving state, the method comprising the steps of:
- detecting a present traffic type of a traffic flow to or from a wireless terminal;
obtaining, from a power state parameter repository, a set of power state parameters corresponding to a plurality of traffic types, including the present traffic type, wherein the plurality of traffic types is in the form of a sequence of traffic types, wherein an initial set of traffic types of the sequence of traffic types, comprises the present traffic type;
transmitting the set of power state parameters to the wireless terminal;
detecting a further traffic type of a traffic flow to or from the wireless terminal;
modifying the power state parameters for the wireless terminal, only when the further traffic type does not comply with at least one expected future traffic type of the plurality of traffic types; and
determining, for at least one initial set of traffic types, a sequence of most likely future traffic types, wherein the sequence of most likely future traffic types ends at a predetermined number of traffic types.

Abstract
A method, performed by a network device, is disclosed for determining a set of power state parameters at least partly defining when a wireless terminal is to be in an active state or a power saving state. The method includes the steps of: detecting a present traffic type of a traffic flow to or from a wireless terminal; obtaining, from a power state parameter repository, a set of power state parameters corresponding to a plurality of traffic types, including the present traffic type; transmitting the set of power state parameters to the wireless terminal; detecting a further traffic type of a traffic flow to or from the wireless terminal; and modifying the power state parameters for the wireless terminal, only when the further traffic type does not comply with at least one expected future traffic type of the plurality of traffic types.

6. A network device arranged to determine a set of power state parameters at least partly defining when a wireless terminal is to be in an active state or a power saving state, the network device comprising:
-
a processor; and a memory storing instructions that, when executed by the processor, causes the network device to; detect a present traffic type of a traffic flow to or from a wireless terminal; obtain, from a power state parameter repository, a set of power state parameters corresponding to a plurality of traffic types, including the present traffic type, wherein the plurality of traffic types is in the form of a sequence of traffic types, wherein an initial set of traffic types of the sequence of traffic types comprises the present traffic type; transmit the set of power state parameters to the wireless terminal; detect a further traffic type of a traffic flow to or from the wireless terminal; and modify the power state parameters for the wireless terminal, only when the further traffic type does not comply with at least one expected future traffic type of the plurality of traffic types; and determine, for at least one initial traffic type, a sequence of most likely traffic types, wherein the instructions to determine the sequence comprise instructions to end the sequence at a predetermined number of traffic types. - View Dependent Claims (7, 8, 9, 10)

11. A method, performed by a network device, for determining a set of power state parameters at least partly defining when a wireless terminal is to be in an active state or a power saving state, the method comprising the steps of:
-
detecting a present traffic type of a traffic flow to or from a wireless terminal; obtaining, from a power state parameter repository, a set of power state parameters corresponding to a plurality of traffic types, including the present traffic type, wherein the plurality of traffic types is in the form of a sequence of traffic types, wherein an initial set of traffic types of the sequence of traffic types, comprises the present traffic type; transmitting the set of power state parameters to the wireless terminal; detecting a further traffic type of a traffic flow to or from the wireless terminal; modifying the power state parameters for the wireless terminal, only when the further traffic type does not comply with at least one expected future traffic type of the plurality of traffic types; and determining, for at least one initial set of traffic types, a sequence of most likely future traffic types, wherein the sequence ends when an expected sequence duration exceeds a threshold value. - View Dependent Claims (12, 13, 14, 15)
