Description

State transition method, device, terminal and computer readable storage medium
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a state transition method, an apparatus, a terminal, and a computer-readable storage medium.
Background
(1) UE energy saving State (energy saving mode)
With the development of wireless communication systems, terminal types and service types are diversified, and the terminal saves power, saves network resources, and meets the requirements of various service types. In order to ensure that the terminal saves power and the service can be reached, a WUS (wakeup signal) is introduced, the power consumption of the terminal during monitoring the WUS is relatively low, when the terminal receives the wakeup signal, the terminal is awakened by the wakeup signal, and then a communication module is started (the power consumption is relatively high) so as to receive a paging message (paging), or receive a PDCCH, or perform RRM (Radio resource management) measurement, or receive a synchronization message, so that the purpose of saving power of the terminal is achieved.
Fig. 1 and fig. 2 respectively show schematic diagrams of sending wake-up signals in an RRC idle state and a connected state, when a UE is in an idle state, the UE may enter a sleep state with extremely low power, when downlink data is to be sent to the UE on a network side, the UE sends the wake-up signal to the UE, and after receiving the wake-up signal, the UE wakes up to start sending and receiving data with the network side. After the data transceiving is completed, the UE enters the sleep state with extremely low power again. Similarly, when the terminal is in an RRC connected state, the terminal may enter an inactive (inactive) state, and enter a sleep state with a very low power, and when downlink data needs to be received by the UE, the network may send a wake-up signal to the UE, and the UE is woken up after receiving the wake-up signal and starts to perform data transceiving with the network. Through the mode, the purpose of saving power for the UE can be achieved. Wherein PO in the figure represents: paging occasion, paging cycle; detect WUS indicates: detecting a power saving signal; detect Paging and decoding PDCCH indicates: detecting a paging signal and decoding a PDCCH; the Monitoring and decoding PDCCH indicates that: monitoring and decoding the PDCCH; I-DRX-cycle denotes: idle (inactive) DRX cycle, unconnected DRX cycle; DRX represents: discontinuous Reception; C-DRX-cycle indicates: a connection DRX cycle, a connected DRX cycle; tx denotes: sending; rx represents: and receiving.
Currently, MTC (machine type communication) based on LTE (Long term evolution), NB-IOT (Narrow band Internet of things), all use WUS to achieve the purpose of further energy saving.
Based on the above description, there is a preliminary definition for the energy saving modes in the connected state and the idle state, but there is no clear method for how the UE performs state transition with the normal state or the energy saving state of the idle state in various energy saving modes of the connected state.
The connection state may be considered as a normal state when no WUS is used, and a power saving state when monitoring is performed by using the WUS.
(2) RRC state transition
The RRC state of the UE may be divided into a CONNECTED state (RRC _ CONNECTED), an IDLE state (RRC _ IDLE), and an INACTIVE state (RRC _ INACTIVE).
The UE enters the CONNECTED state through an RRC connection setup (connection setup) procedure in the IDLE state, and the UE enters the CONNECTED state through an RRC recovery (RRC resume) procedure in the INACTIVE state.
The CONNECTED state UE may enter the IDLE state or the INACTIVE state through an RRC release (RRC release) procedure or an RRC reject (RRC reject) procedure.
That is, the UE transitioning from the RRC _ CONNECTED normal data transmission state to RRC _ IDLE or RRC _ INACTIVE may send an explicit RRC release message to the UE through the network, instructing the UE to enter IDLE or INACTIVE state and instructing the UE to enter IDLE or INACTIVE state related behaviors (redirection information, dedicated cell reselection information, system priority information, RAN area information, etc.).
However, if the energy saving mechanism is introduced, the UE does not perform data transmission with the network in the energy saving mode itself, and other ways may be needed to control the state entered by the UE and the behavior of the UE thereafter. The RRC _ CONNECTED state itself may be classified into a normal mode, an energy saving mode, and other states, and the RRC _ IDLE and the RRC _ INACTIVE may also be classified into a normal mode, an energy saving mode, and other states, but there is no clear method for the UE to transition among these sub-states.

b. when the terminal works in the energy-saving mode of the connected state and the related timer of the connected state transition is overtime and the UE does not support the related energy-saving capability of the non-connected state (the terminal capability of the terminal does not support the energy-saving capability of the non-connected state); of course, it is also possible that the UE does not have the associated energy saving capabilities of IDLE and INACTIVE;
c. when the terminal works in the energy-saving mode of the connected state and the related timer of the connected state transition is overtime and the network node does not support the related energy-saving capability of the unconnected state; of course, it is also possible here that the network node does not have the associated energy saving capabilities of IDLE and INACTIVE;
d. and the terminal works in the energy-saving mode of the connected state, the related timer of the connected state transition is overtime, and the terminal does not store the energy-saving configuration of the unconnected state.
Specifically, the method comprises the following steps:
with regard to: condition setting for transition of the connected state energy saving mode to the unconnected state (IDLE or INACTIVE);
when the UE works in the energy-saving mode in a connected state, the UE may only monitor the WUS in the downlink, and once the WUS for the current UE and/or the current UE group (for all terminals of the group where the current UE is located) and/or for all the UEs in the cell or the active area where the current UE is located is monitored, the normal monitoring of the physical downlink control channel PDCCH is allowed to be started.
Because the UE does not directly monitor the PDCCH when in the energy saving mode, the node on the network side cannot explicitly indicate to the UE to request release of the RRC connection. However, the network may configure a connection state transition Timer for the UE in an explicit or implicit manner, and when the Timer times out, the UE leaves the energy saving mode in the connection state and enters the non-connection state.
The configuration time of the Timer includes at least one of the following:
(1) the method comprises the following steps of sending down through a special signaling when in a non-energy-saving mode in a connected state;
(2) WUS indication of power save mode by connected state;
(3) the protocol sets a fixed length of time.
The Timer configuration mode includes at least one of the following:
(1) the network explicitly configures a timer time length;
(2) the network configures a scaling factor, and the UE obtains the length of the Timer of the state transition Timer by taking the length value of the existing Timer as the product of the scaling factor (for example, the energy saving of the connection state has a Timer, and the state transition Timer can perform length scaling by taking the Timer as a reference);
(3) the protocol specifies a fixed timer length.
The starting condition of the Timer comprises at least one of the following conditions:
(1) the UE may be started after entering the connected state energy saving mode;
(2) when the UE has multiple energy saving modes, the UE is activated when entering the energy saving mode with the highest energy saving efficiency in the connected state (it can be understood that the connected state may have multiple energy saving sub-modes, for example, the energy saving mode two is more power saving than the energy saving mode one.
The termination condition of the Timer includes at least one of the following:
(1) the Timer is terminated when the WUS monitored by the UE is a WUS for the current UE and/or for the current group of UEs (for all terminals in the group where the current UE is located) and/or for all UEs within the cell or active area where the current UE is located. The WUS may:
a. requiring the UE to enter a normal mode of a connection state, starting normal monitoring of a PDCCH, and subsequently receiving and transmitting data;
b. or, the UE is required to enter other energy saving modes and continue to monitor the WUS in the mode (the energy saving mode that the UE newly enters).
(2) When the UE needs to send uplink data (the WUS and the PDCCH monitor whether downlink data exists or not, wherein the uplink data exists in the UE and needs to be sent, for example, a user needs to upload data to a network), the Timer is stopped, and a normal mode in a connection state is entered; further, the uplink data is sent by using the uplink resource allocated by the network to the UE, or a resource request indication is sent to a node on the network side when there is not enough uplink resource.
In this description, in the embodiment of the present invention, the network side needs to be modified for WUS: in the prior art, before sending data, a node on a network side sends a WUS to inform UE to start monitoring a PDCCH. However, in the embodiment of the present invention, the mode of sending the WUS by the node on the network side is not unique, and may be sending the WUS to one UE, a group of UEs, or all UEs in a certain area, and then the differentiation mode of the UE or the group of UEs may be a UE ID, a cell ID, or another newly added differentiation identifier, and so on.
With regard to: connected state energy saving mode to non-connected state (IDLE or INACTIVE) energy saving mode-decision is set according to activation region;
and when the UE works in the energy-saving mode in the connected state and the state transition Timer times out, the UE enters the unconnected state. If the UE determines the energy saving state of the UE using an active area (e.g., wakeup-area), the UE directly enters the energy saving state (mode) in the unconnected state when the cell in which the UE is located is within the active area when the UE enters the unconnected state.
If the network explicitly gives the active area configuration, the UE may be notified as follows:
(1) before the UE enters a connected state energy-saving mode, the network configures an activation region used by the UE in a normal data transceiving mode (a normal mode of a connected state) through an explicit RRC (radio resource control) signaling, stores the activation region in the UE and can be used for activating wakeup of subsequent UE;
(2) or, the UE reads the activation region (without limiting the reading time) through system broadcast, and the activation region is not specific to the UE, but is uniformly divided by the network side, and all UEs in the cell use the same activation region;
if the network does not explicitly give the active area configuration, it may:
(1) consider that the UE has no active area;
(2) or, the cell where the current UE is located is the active area by default.
Wherein, the negotiation with the network is not required for the autonomous default of the UE.
When the UE obtains the active area by any of the above manners and the cell in which the UE is located is within the active area when the UE enters the non-connected state, the UE may directly enter the energy saving mode when entering the non-connected state. The behavior of the energy-saving mode may be to monitor the WUS first in a non-connected state, and monitor the PDCCH to acquire a paging message only when there is a WUS for the current UE and/or for a current UE group and/or for all UEs in a cell or an active area where the current UE is located;
and when the UE cannot obtain the active area by any of the above manners, or obtains the active area but is not located in the active area, it is determined that the UE needs to enter the normal mode when the UE is in the non-connected state. The normal mode is to not monitor the WUS, and directly monitor the PDCCH to acquire a Paging message as long as a Paging opportunity (Paging interference) of the UE is entered.
With regard to: connected state energy saving mode to non-connected state (IDLE or INACTIVE) energy saving mode-decision according to UE and/or network side (network node) capability;
and when the UE works in the energy-saving mode in the connected state and the state transition Timer times out, the UE enters the unconnected state.
(1) If the UE only supports the energy saving in the connected state aiming at the energy saving related capacity but does not support the energy saving in the non-connected state, the UE directly enters a normal mode when entering the non-connected state; of course, the UE may not support the IDLE and INACTIVE related power saving capabilities.
(2) If the network side (network node) only supports the connected state energy saving for the energy saving related capability but does not support the non-connected state energy saving, and the UE is informed that the network side (network node) does not support the capability, the UE directly enters a normal mode when entering the non-connected state; of course, the network node may not support IDLE and INACTIVE related energy saving capabilities;
this may be a explicit or implicit notification. Implicit notification, such as when the network does not send the relevant configuration for non-connected power saving, indicates no support.
(3) If the default network side (network node) supports the energy saving in the non-connection state and the UE capability supports the energy saving in the non-connection state, the UE can directly enter the energy saving mode when entering the non-connection state; of course, energy saving in which both the network node and the terminal support IDLE and INACTIVE is also possible here.
(4) If a network side (network node) configures energy saving mode supporting the non-connection state for the UE and the UE capability also supports the energy saving mode in the non-connection state, the UE can directly enter the energy saving mode in the non-connection state; in this case, the default network node may send the configuration only if it supports the non-connected state power saving. Of course, energy saving in which both the network node and the terminal support IDLE and INACTIVE is also possible here.
Regarding the terminal, the network node determines whether the terminal is supported according to the terminal capability of the terminal; the capability of the network node is that the network node itself determines whether or not it supports. Wherein the UE capability is determined by the handset vendor. The network node capabilities are determined by the operator and/or the device vendor.
