Abstract
The present invention relates to a method and arrangements for saving battery power consumption of a UE in mobile telecommunication system. The method comprises the step of checking whether the UE fulfills at least one of the pre-determined criteria that a subscriber explicitly requests to receive paging at extended DRX cycle and that a new cell is not reselected during a pre-determined time. If the at least one of the pre-determined criteria is fulfilled the step of applying an extended DRX cycle is performed.
Claims25
A method for saving battery power consumption of a User Equipment (UE) in a mobile telecommunication system, said method comprising:
- checking whether any predetermined criteria are fulfilled, said predetermined criteria including a request criterion that is fulfilled if the UE explicitly requests to receive paging at an extended DRX cycle, and a reselection criterion that is fulfilled if cell reselection is not performed for the UE for a predetermined period of time;
- and
- applying an extended DRX cycle to the UE, if at least one of the predetermined criteria is fulfilled.
A paging proxy associated with a mobile telecommunication network and comprising:
- input/output circuits configured to receive a paging proxy configuration message indicating that a user equipment (UE) requests an extended DRX cycle, and configured to receive a paging message for the UE from the network and forward the received paging message to the UE;
- and
- a processing circuit configured to control forwarding of the received paging message by the input/output circuits in accordance with the received paging proxy configuration message, such that said input/output circuits forward the received paging message to the UE in accordance with the extended DRX cycle.
A user equipment (UE) for a mobile telecommunication network, said UE adapted to monitor paging information in idle mode in accordance with a configured DRX cycle and comprising:
- a transceiver for communicating with the network;
- and
- one or more processing circuits operatively associated with the transceiver and configured to send a request to extend the DRX cycle for the UE, in response to determining that a request criterion is fulfilled or that a reselection criterion is fulfilled, said one or more processing circuits further configured to consider the request criterion as fulfilled responsive to detecting an explicit request by a user of the UE for an extended DRX cycle, and to consider the reselection criterion as fulfilled responsive to determining that cell reselection has not been performed for the UE for a predetermined period of time.
The UE of 16, wherein the paging information comprises paging indicators.
A core network node of a mobile telecommunication network adapted to extend a DRX cycle for a user equipment (UE) in idle mode and adapted to signal the extended DRX cycle to the UE, wherein the core network node comprises:
- input/output circuits configured for:
- sending a reselection criterion to be used by the UE in determining whether to request use of an extended DRX cycle;
- receiving a request to extend the DRX cycle of the UE;
- and sending paging information for the UE;
- and
- one or more processing circuits operatively associated with the input/output circuits and configured to:
- in response to receiving the request to extend the DRX cycle of the UE, control sending of the paging information for the UE in accordance with the extended DRX cycle;
- and
- wherein the reselection criterion defines a predetermined period of time, and wherein the UE considers the reselection criterion satisfied if no cell reselection for the UE occurs for the predetermined period of time.
