Problems solved by technology

In addition, the existing technology only considers sending the above message when the UE temporarily has no need for further packet service activities, and cannot help the network configure more appropriate DRX parameters or enable the UE to migrate to a more appropriate RRC state faster, and cannot enable the UE to achieve Maximum Power Saving Efficiency

Embodiment 1

[0071] In the UMTS system, the UE informs the UTRAN that it expects to transfer the RRC state from the CELL_DCH state to the CELL_PCH state, such as image 3 As shown, the implementation of the UE power saving method in this embodiment includes the following steps:

[0072] Step 301: After the UE determines in the CELL_DCH state that there will be no demand for packet service data activities for a period of time in the future according to the instructions of the high layer or the characteristics of the service, it determines that it expects to migrate to the CELL_PCH state in combination with its current CELL_DCH state;

[0073] In this step, the high layer refers to the application layer or the non-access layer (NAS);

[0074] This step further includes: when the UE determines that there will be no need for further packet service activities after a certain period of time during the packet service activity, setting a delay time for transitioning to the CELL_PCH state.

Embodiment 2

[0082] In the LTE / LTE-A system, the UE uses the newly added signaling connection release indication or reconfiguration message, or other existing RRC messages to carry its own desired power saving parameters, such as Figure 4 As shown, the implementation of the UE power saving method in this embodiment includes the following steps:

[0083] Step 401: After the UE determines in the RRC_CONNECTED state that there will be no packet service data activity requirements for a period of time in the future according to the instructions of the high layer or the characteristics of the service, it determines that it expects to migrate to the RRC_IDLE state in combination with its current RRC_CONNECTED state, or short DRX cycle, or DRX parameters , or switch to a long DRX cycle, or reconfigure DRX parameters;

[0084] In this step, the high layer refers to the application layer or NAS;

[0085] This step further includes: when the UE determines that there will be no need for further pack...

Embodiment 3

[0102] In the UMTS evolved multi-carrier system or the LTE-A carrier aggregation system, the UE uses existing or newly added signaling connection release or reconfiguration messages, or other existing RRC messages to notify the network side of its desired carrier aggregation configuration information, For example, deactivate or configure one or more secondary cells or secondary carriers, such as Figure 5 As shown, the implementation of the UE power saving method in this embodiment includes the following steps:

[0103] Step 501: UE in the CELL_DCH of UMTS or RRC_CONNECTED state of LTE-A determines the desired deactivation and / or based on its current carrier aggregation configuration after determining that there will be no packet service data activity requirements for a period of time in the future according to the instructions of the high layer or the characteristics of the service Or to configure at least one secondary cell or secondary carrier;

[0104] In this step, the h...

Abstract

The invention discloses a method of user equipment (UE) power saving. UE notifies a network side of a self-expected power saving parameter through a special signaling, and the network side carries out a power saving configuration for the UE according to the power saving parameter. The invention also discloses a system of UE power saving. The method and the system of the invention assists in solving the problem that in the prior art network sides have difficulties in carrying out accurate scheduling decisions according to indication messages released by UE signaling, enabling the UE to transfer to a more appropriate radio resource control (RRC) state more promptly or to configure a more appropriate discontinuous reception (DRX) parameter, improving power saving efficiency of UE, and making a balance between business delays and power saving efficiency.

Description

technical field [0001] The present invention relates to mobile communication technology, and in particular to a method and system for saving power of user equipment (UE, User Equipment). Background technique [0002] The UE in the Terrestrial Radio Access Network (UTRAN, UMTS Terrestrial Radio Access Network) (referred to as the network) of the Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications Services) of the Third Generation Partnership Project (3GPP, Third Generation Partnership Projects) The two basic working modes are idle mode (IDLE) and radio resource control (RRC, Radio Resource Control) connected mode (CONNECTED). In the connection mode, UE can be in four states according to the service characteristics and the type of the allocated transmission channel: cell_dedicated channel state (CELL_DCH), cell_forward access channel state (CELL_FACH), cell_paging channel state state (CELL_PCH) and UTRAN registration area_paging channel state...
