A method in a client node in a communications system, for resetting of timer units, the client node comprising at least two timer units, the method comprising: for each of the at least two timer units: - detecting each timer unit by a timer handling unit, - registering the detected timer unit in a timer inventory by the timer handling unit, the method further comprising: - determining, by the timer handling unit, a timer unit of the at least two timer units that expires first, - determining, by the timer handling unit, a time, T, at which the determined timer unit will be reset, - resetting, prior to expiry of the time, T, by the timer handling unit, at least one of the other timer units of the at least two timer units, with a new reset time, based on the time, T, wherein one or more reset events are triggered by the timer handling unit, when the at least one of the other timer units reaches the expiry of the time, T, or a user action in the client node, - determining, by the timer handling unit, a priority of the one or more reset events associated with said resetting of the at least one of the other timer units, based on one of high priority reset events and low priority reset events, wherein the high priority reset events relates to at least one of telephony related timers or network connectivity related timers, - muting one of a reset event of the reset events or a group of reset events, by the timer handling unit, when the reset event of the reset events or the group of reset events are determined to belong to the low priority reset events, and - initiating the muted reset event together with another reset event at a later point in time, thereby enabling longer radio and CPU sleep periods of the client node between reset of timer units. for each of the at least two timer units: - detecting each timer unit by a timer handling unit, - registering the detected timer unit in a timer inventory by the timer handling unit, - detecting each timer unit by a timer handling unit, - registering the detected timer unit in a timer inventory by the timer handling unit, the method further comprising: - determining, by the timer handling unit, a timer unit of the at least two timer units that expires first, - determining, by the timer handling unit, a time, T, at which the determined timer unit will be reset, - resetting, prior to expiry of the time, T, by the timer handling unit, at least one of the other timer units of the at least two timer units, with a new reset time, based on the time, T, wherein one or more reset events are triggered by the timer handling unit, when the at least one of the other timer units reaches the expiry of the time, T, or a user action in the client node, - determining, by the timer handling unit, a priority of the one or more reset events associated with said resetting of the at least one of the other timer units, based on one of high priority reset events and low priority reset events, wherein the high priority reset events relates to at least one of telephony related timers or network connectivity related timers, - muting one of a reset event of the reset events or a group of reset events, by the timer handling unit, when the reset event of the reset events or the group of reset events are determined to belong to the low priority reset events, and - initiating the muted reset event together with another reset event at a later point in time, thereby enabling longer radio and CPU sleep periods of the client node between reset of timer units. - determining, by the timer handling unit, a timer unit of the at least two timer units that expires first, - determining, by the timer handling unit, a time, T, at which the determined timer unit will be reset, - resetting, prior to expiry of the time, T, by the timer handling unit, at least one of the other timer units of the at least two timer units, with a new reset time, based on the time, T, wherein one or more reset events are triggered by the timer handling unit, when the at least one of the other timer units reaches the expiry of the time, T, or a user action in the client node, - determining, by the timer handling unit, a priority of the one or more reset events associated with said resetting of the at least one of the other timer units, based on one of high priority reset events and low priority reset events, wherein the high priority reset events relates to at least one of telephony related timers or network connectivity related timers, - muting one of a reset event of the reset events or a group of reset events, by the timer handling unit, when the reset event of the reset events or the group of reset events are determined to belong to the low priority reset events, and - initiating the muted reset event together with another reset event at a later point in time, thereby enabling longer radio and CPU sleep periods of the client node between reset of timer units.
