The embodiments of the present disclosure do not limit that these numbered steps must be executed, that is, these steps can be combined in any combination to form different embodiments.

As shown in FIG. 2, an embodiment of the present disclosure provides a method for processing terminal state switching, wherein the method includes:

S110: Enter the inactive state of the downlink mode; wherein, in the inactive state of the downlink mode, the terminal can receive downlink service data.

The embodiments of the present disclosure can be applied to a light terminal. The lightweight terminal may have one or more of the following characteristics:

Receiving antennas (RX) are reduced, from 4 in R15 to 2 or 1; this light terminal has fewer receiving antennas than eMBB terminals supporting eMBB services.

The bandwidth is reduced, the typical value of FR1 is 5MHz/10MHz, and the typical value of FR2 is 40MHz; this lightweight terminal supports a smaller bandwidth than eMBB terminals.

Processing capacity is reduced; it may support smaller transmission block (Transmission Block, TB) size (Transmission Block, TB) and downlink control information (Dwonlink Control Information, DCI) size (size); The processing capability of the CPU includes but is not limited to: the decoding rate is lower than the decoding rate of the eMBB terminal, and/or the encoding rate is lower than the encoding rate of the eMBB terminal.

Lower mobility. The light terminal may be a fixed terminal or a terminal with a relatively small moving range.

In the embodiment of the present disclosure, a new terminal state is proposed, that is, the inactive state of the downlink mode of the terminal.

The inactive state of the downlink mode here can also be referred to as the inactive state of the downlink only mode, and the corresponding should be: Downlink only RRC-INACTIVE.

When the terminal is in the inactive state of the downlink mode, the reception of downlink service data of the terminal is allowed. The reception of downlink service data here includes: reception of downlink service data.

In this state, the terminal can only open the receiving processing path in the terminal, that is, the terminal can close the transmission signal processing path (ie, the uplink signal processing path), thereby reducing the power consumption caused by the transmission link in the open state. And because the receiving link of the terminal is opened, in this way, the downlink service data can be received without delay or with low delay, and the receiving delay of the downlink service data is reduced.

The inactive state of this downlink mode can be a terminal type that is obviously prominent for the amount of downlink service data reception. For example, a type of terminal whose difference between the amount of received downlink service data and the amount of transmitted uplink service data is greater than the difference threshold.

This type of terminal includes, but is not limited to, tracking and positioning terminals. Typical tracking and positioning terminals include, but are not limited to: navigation equipment. The navigation device includes, but is not limited to: a car navigation device and/or a human navigation device.

Since the terminal has more downlink service data and less uplink service data, the downlink service data reception of the terminal in the inactive state of the downlink mode is not blocked, which can ensure the timeliness of downlink service data reception. At the same time, the transmission of uplink service data is blocked, which can reduce the fact that the terminal has only a small amount of uplink service data, and also performs state switching or sending, resulting in frequent uplink service data transmission and/or frequent state switching.

In some embodiments, in the inactive state of the downlink mode, the uplink service data transmission of the terminal is blocked.

Since the transmission of the uplink service data of the terminal is blocked, the terminal can turn off the transmission of the uplink service data, thereby reducing the power consumption of the terminal as much as possible. The blocking of uplink service data does not mean that the uplink signaling is blocked. For example, the uplink signaling can also be sent normally, which facilitates the interaction between the terminal and the base station through the uplink signaling, and realizes the state switching of the terminal.

In some embodiments, as shown in FIG. 3A, the method further includes:

S120: The terminal in the inactive state in the downlink mode determines a recovery request for sending uplink service data.

The recovery request for sending uplink service data includes: the recovery request is used for requesting to send uplink service data, or the recovery request itself carries a relatively small amount of uplink service data. The restoration request itself carries a relatively small amount of uplink service data, which means that the restoration request may include request information and/or uplink service data.

For example, the formation of the restoration request includes:

S120: In response to sending uplink service data, determine a recovery request; wherein, the recovery request is used to request recovery to the connected state or any other appropriate state. Any other appropriate state here includes, but is not limited to: a connected state or an inactive state in a normal mode.

If the terminal is in the inactive state of the downlink mode, and if the terminal has uplink service data to send, the terminal may send a recovery request to the base station to request to restore to the connected state. When the terminal is restored to the connected state, the base station will establish an RRC connection with the terminal, and the RRC connection can be used to transmit control commands and/or data.

It is worth noting that the determination of the restoration request here includes: forming a restoration request in the terminal, for example, generating a restoration request to be sent according to the information format of the restoration request.

In some embodiments of the present disclosure, the recovery request is a kind of uplink signaling.

[Corrected 10.08.2020 according to Rule 91]
In some embodiments, as shown in FIG. 3B, the method further includes:

S130: In response to determining the recovery request, enter the suspended state of the recovery request.

In some embodiments, after entering the suspended state, it waits for the suspended state to be unlocked; if it is unlocked, a definite resume request is sent.

In other embodiments, in the suspended state, waiting to receive a paging message sent by the base station. The paging message can be used to unlock the suspended state.

In response to sending the resume request, the terminal enters the suspended state of the resume request. In the suspended state, the terminal waits for a paging message sent by the base station. If a paging message is received, the terminal will establish an RRC connection with the base station, thereby switching from the inactive state of the downlink mode to the connected state.

After entering the connected state, the uplink service data can be sent through the RRC connection.

In some embodiments, the method further includes:

In response to entering the suspended state, start a first timer;

Maintain the suspended state within the timed time of the first timer.

When entering the suspended state, the first timer is started; the suspended state is maintained during the timed time of the first timer. Exit the suspended state when the first timer expires.

In all embodiments of the present disclosure, the terminal may be maintained in the suspended state before the first timer overflows. In all embodiments of the present disclosure, the terminal may exit the suspended state when the first timer overflows.

In all the embodiments of the present disclosure, the terminal may exit the suspended state when receiving a paging message; that is, no matter whether the first timer overflows or not, the terminal may exit the suspended state in response to receiving the paging message. The suspended state.

The paging message may be a radio access network (Radio Access Network, RAN) paging message, and the message content, message format, or sending mode of the RAN paging message may be the same as the paging message in the normal mode.

Once the terminal enters the suspended state, it can be considered that the terminal has suspended uplink transmission; during this period, the terminal can close the uplink signal processing path in the terminal to further reduce the power consumption in the terminal.

In some embodiments, the method further includes:

When the condition for releasing the suspended state is satisfied, the suspended state is released.

There are many situations in which the conditions for releasing the suspended state are met. The following two options are provided:

method one:

In response to the expiration of the first timer, the suspended state is released. The first timer may also be referred to as a suspended state timer, which is a timer used to time the terminal into the suspended state triggered by the resume request.

Way two:

In response to receiving the paging message, the suspended state is released.

If within the timing time of the first timer, that is, the first timer does not expire and the paging message sent by the base station is received, the suspension state is released.

In some embodiments, in response to receiving the paging message, the timing of the first timer is stopped.

In some embodiments, in response to receiving the paging message or in response to exiting the suspended state, the first timer is reset.

After the suspended state is released, the terminal can continue to send the resume request.

In some embodiments, the method further includes:

Receiving duration information of the first timer;

or,

Determine the duration information of the first timer according to the protocol.

In all the embodiments of the present disclosure, the duration information of the first timer may be sent in advance by the base station, for example, sent through a system information (System Information, SI). Still further, it is sent using a broadcast system message, or sent according to a terminal on-demand system message on-demand request message. At this time, the terminal can send the timing by unicasting the system message to a specific terminal according to the request information. information.

In all embodiments of the present disclosure, the duration information of the first timer may also be determined according to the provisions of the protocol; or determined after negotiation between the base station and the terminal; or determined based on the parameters uploaded by the terminal.

The duration information includes at least: timing duration information of the timer, which is used to indicate the timing duration of the timer.

In an embodiment, the timing length information of the timer may be infinite.

In another embodiment, the timing length information of the timer may be based on statistical data to determine the time from when the recovery request is paged. That is, the timing length information of the timer is determined according to the historical time length from the time when the recovery request is determined to the time that it is paged.

In another embodiment, the timing information of the first timer may also be specified in a communication protocol. At this time, the terminal is configured with the duration information of the first timer.

In an embodiment, the first timer may not be set in the terminal, and the terminal will exit the suspended state or the inactive state of the downlink mode only when it receives paging information.

When the time duration of the first timer is not infinite, it means that the terminal will automatically release the suspended state, thereby removing the time for the terminal to wait for the base station to send a paging message, and reducing the terminal's indefinite waiting for a paging message.

The above is only an example of the suspension condition release condition, and the specific implementation is not limited to the above example.

In some embodiments, the receiving timing information of the first timer includes:

Receiving the duration information of the first timer sent through downlink signaling;

or,

Receiving the duration information of the first timer that is sent through system message broadcasting.

In some embodiments, the downlink signaling includes, but is not limited to, unicast signaling, that is, signaling sent to the UE in a unicast manner.

The downlink signaling includes but is not limited to RRC signaling. By sending the duration information of the first timer in a unicast manner through RRC signaling, the duration information of the first timer can be flexibly set for different terminals and/or different types of terminals.

In all embodiments of the present disclosure, the duration information of the first timer may be sent by the base station, for example, sent through a system information (System Information, SI).

In another embodiment, it is sent using a broadcast system message, or sent according to a terminal on-demand system message on-demand request message. At this time, the terminal may send the timing information through a system message unicast to the specific terminal according to the request information.

In all embodiments of the present disclosure, the duration information of the first timer may also be determined according to the provisions of the protocol; or determined after negotiation between the base station and the terminal; or determined based on the parameters uploaded by the terminal; or the terminal Determined by yourself.

In all embodiments of the present disclosure, if there are multiple same terminals or terminals with the same service requirements in the cell, the duration information of the first timer can be broadcast through the system message. In this way, the system messages broadcast by multiple terminals The duration information can be received at the same time, which reduces the signaling overhead of the base station.

In all the embodiments of the present disclosure, the terminal can be grouped to determine whether the terminal receives the system message broadcast duration information of the first timer; or the terminal is grouped to determine whether the terminal applies the system message Broadcast the duration information of the first timer. That is, in some embodiments, the duration information of the first timer may be carried in a multicast message sent in a multicast manner.

In some embodiments, the identifier of the UE group can be added to the system message.

In all the embodiments of the present disclosure, terminal grouping can be performed based on terminal parameters such as the type of the terminal, the transmission capability of the terminal, and/or the codec capability of the terminal.

In some embodiments, as shown in FIG. 4, the method further includes:

S140: In response to the suspension state being released or in response to exiting the inactive state of the downlink mode, send the resume request.

If the suspended state is released, the terminal can send the determined resume request. Of course, the terminal can also, according to requirements, if the suspended state is released, first buffer the uplink service data that needs to be reported, and suspend the sending of the resume request.

In some embodiments, the resume request carries a reason for the call;

The reason for the call includes: initiating a call (Mobile Original, MO) and/or receiving a call (Mobile Terminated, MT).

The uplink service data transmission may be because of the uplink service data transmission during the calling process, or the uplink service data transmission during the called process.

In some other embodiments, the recovery request may carry uplink service data that needs to be reported to the base station, or uplink service data transmitted by the base station to the receiving end. If the recovery request directly carries the uplink service data, at this time, the data volume of the uplink service data is usually relatively small, for example, less than the data volume threshold.

In some embodiments, the method further includes:

Receiving the status indication after the recovery request is sent; the status indication is used to indicate the state the terminal is in.

The state indication can indicate that the terminal enters any state, for example, including but not limited to:

Connected state, idle state, inactive state in normal mode, or inactive state in downlink mode.

For example, the base station can determine the state that the terminal needs to enter according to any one or more of the type of terminal, the capabilities of the terminal, the downlink service data that the base station currently needs to send to the terminal, and the data that needs to be received from the terminal. The status indication informs the terminal.

The status indication may be sent by the base station after receiving the recovery request reported by the terminal, for example, sent to the terminal through a Physical Downlink Control Channel (PDCCH).

After receiving the status indication, the terminal will enter the state corresponding to the status indication. If the state corresponding to the state indication is different from the current state of the terminal, the terminal will switch the state, and if the state indicated by the state is the current state of the terminal, the terminal maintains the current state.

In some embodiments, the method further includes:

After switching to the connected state according to the state indication, the uplink service data is sent.

If the amount of uplink service data to be sent by the terminal is relatively large, for example, greater than the amount of data that can be carried in the recovery request, the terminal may request to send the uplink service data after entering the connected state. At this time, after receiving the recovery request that does not carry the uplink service data, or the recovery request that carries the request information to enter the connected state, the base station may send a state indication of entering the connected state to the terminal.

After receiving the instruction, the terminal will enter the connected state, and report the uplink service data to the base station after entering the connected state.

In some embodiments, the performing state switching according to the state indication includes:

In response to the uplink service data carried in the recovery request, it is determined according to the status indication that the terminal is in the inactive state of the downlink mode, the inactive state or the idle state of the normal mode.

If the amount of uplink service data that the terminal needs to send is small and can be carried in one or more recovery requests, the recovery request can also be used to directly carry the uplink service data. In this way, the connection instruction sent by the base station after receiving the recovery request can instruct the terminal to continue to maintain the inactive state in the downlink mode, enter the inactive state in the normal mode, or enter the idle state. Of course, the base station can also control the terminal to enter the connected state according to one or more of the communication requirements between itself and the terminal, the type of the terminal, and the communication capability of the terminal; at this time, the connection instruction can also instruct the terminal to enter the connection. state.

In the embodiment of the present disclosure, the status indication may be a semi-static control command, which will be sent based on a semi-static cycle.

In some embodiments, the control command may be periodically sent at the corresponding transmission resource location, or periodically sent at the corresponding time point.

In some embodiments, the method further includes:

The inactive state terminal in the downlink mode periodically updates the RNAU in the wireless network notification area;

or,

The inactive state terminal in the downlink mode performs RNAU in response to the change of the wireless network notification area of the terminal.

In the inactive state of the downlink mode, the terminal can perform RNAU normally, that is, the RNAU of the terminal is not affected by the aforementioned suspended state.

Performing the RANU by the terminal may include: determining a recovery request; the determination of the recovery request is not affected by the formation of a suspended state. That is, in response to the recovery request determined by RNAU, once determined, it can be sent directly without being blocked in the terminal waiting for the suspension of the suspension state.

In some embodiments, the inactive state of the downlink mode is an inactive state independent of the regular mode.

The inactive state of the normal mode is different from the inactive state of the downlink mode. The resume request formed in the inactive state of the normal mode does not trigger the suspended state of the resume request, but is sent after the resume request is formed.

In some embodiments, the method further includes:

In response to being in the connected state, receive a connection release message;

The inactive state of entering the downlink mode includes:

In response to the connection release message carrying indication information indicating to enter the inactive state of the downlink mode, exit the connected state and enter the inactive state of the downlink mode.

If the inactive state of the downlink mode is independent of the inactive state of the normal mode, that is, the inactive state of the downlink mode is a parallel state with the inactive state of the normal mode, the base station can directly instruct the terminal to enter the downlink mode. Inactive state.

Therefore, when the base station instructs the terminal to release the connection, it can directly instruct the terminal to enter the inactive state of the downlink mode. At this time, the connection release message received by the terminal will carry indication information indicating to enter the inactive state of the downlink mode. The terminal can then switch to the inactive state of the downlink mode according to the indication information in the connection release message.

In some embodiments, the inactive state of the downlink mode belongs to: a sub-mode of the inactive state of the normal mode. That is, the terminal can only directly enter the inactive state of the normal mode from the connected state or the idle state, and then enter the inactive state of the downlink mode from the inactive state of the normal mode. Or, the terminal is in the inactive state of the normal mode, and can enter the inactive state of the downlink mode based on a trigger event.

At this time, the inactive state includes one or more, such as:

Inactive state of downlink mode;

The inactive state of the conventional mode; the inactive state of the conventional mode here is the inactive state in the related art (also called the RRC inactive state).

In some embodiments, the method further includes:

In response to the connection release message carrying the indication information to enter the inactive state of the normal mode, exit the connected state and enter the inactive state of the normal mode;

The inactive state of entering the downlink mode includes:

In response to an event-based trigger, the inactive state of the normal mode enters the inactive state of the downlink mode.

In the embodiment of the present disclosure, the terminal is in the inactive state of the normal mode, and can enter the inactive state of the downlink mode based on a trigger event. The trigger event includes at least one of the following:

Responsive to receiving an entry indicating the inactive state from the inactive state of the normal mode to enter the inactive state of the downlink mode in the inactive state of the normal mode, exit the inactive state of the normal mode to enter the downlink mode Inactive state;

In response to the timeout of the second timer in the inactive state of entering the normal mode, exit the inactive state of the normal mode and enter the inactive state of the downlink mode;

In response to the number of times of sending recovery requests triggered by the uplink service data within the preset time interval is lower than the threshold, exit from the inactive state of the normal mode and enter the inactive state of the downlink mode. Among them, the preset preset time interval can be set arbitrarily, which is not limited in the embodiment of the present disclosure. For example, the preset preset time interval may be a time interval before the current moment.

In the embodiment of the present disclosure, if the inactive state of the downlink mode is a special state belonging to the inactive state of the regular mode, the base station will first instruct the terminal to enter the inactive state of the regular mode. The terminal further enters the inactive state of the downlink mode in response to the event, that is, enters a special state in the inactive state of the normal mode from the inactive state of the normal mode: the inactive state of the downlink mode.

For example, receiving instructions from the base station. The indication information may be information dynamically sent by the base station.

In some embodiments, the indication information is carried in the medium access control MAC control unit CE; alternatively, the indication information is carried in the downlink control information DCI.

In response to receiving the recovery request, the base station may determine whether to send a paging message according to its current load and/or wireless environment, so as to release the suspended state of the recovery request of the terminal or release the inactive state of the downlink mode.

Of course, after receiving the recovery request, the base station may not immediately send a paging message to the terminal or refuse to send a paging message to the terminal.

However, in response to receiving downlink service data or other trigger events sent to the terminal from the core network, the base station sends the paging message to the terminal. The paging message can also be used to trigger the terminal to exit the suspended state or exit the downlink mode. The active state or the paging message can also be used purely to page the UE.

In an embodiment, the paging message here may be a paging message sent by the base station according to whether there is a paging demand, and it may not be sent for releasing the suspended state of the recovery request in the terminal. However, when the paging message is sent to the terminal, if the terminal has determined the resume request, and the terminal is in the suspended state of the resume request or the inactive state of the downlink mode, the paging message can trigger the terminal to release the resume request.

If the connection release message carries indication information indicating that the terminal enters the inactive state of the downlink mode, after the terminal receives the connection release message, It will exit the current state, such as the connected state or the idle state, and enter the inactive state of the downlink mode.

In some embodiments, the inactive state of the downlink mode belongs to: a sub-mode of the inactive state of the normal mode.

If the inactive state of the downlink mode is a sub-mode of the inactive state of the normal mode, and you need to enter the inactive state of the downlink mode at this time, you need to enter the inactive state of the normal mode first; then enter the inactive state of the normal mode The inactive state of the downlink mode. In view of this, the sending of the control signaling that triggers the terminal to enter the inactive state of the downlink mode includes:

The auxiliary information may be carried in the recovery request, or any information of the independent recovery request, for example, carried in uplink control information (UCI).

A specific example is provided below in conjunction with any of the foregoing embodiments:

The inactive state of the regular mode is a working mode that is more suitable for IoT terminals. The inactive state in the conventional mode here may be the inactive state in related technologies or the RRC inactive state.

But for many IoT devices, there are usually some special requirements. For example, some IoT devices have only downlink transmission requirements, such as tracking and positioning terminals, and do not need an independent uplink mode, that is, the transmission of uplink service data only needs to be after the downlink transmission. Therefore, it can be optimized for the working mode of the Internet of Things devices working in the inactive state.

Introduce the inactive state (Downlink only RRC-INACTIVE) in the downlink only mode;

As an embodiment, the inactive state of the downlink mode is a sub-state of the inactive state.

As an embodiment, the inactive state of the downlink mode is a state that runs independently of the inactive state.

As an embodiment, the inactive state of the downlink mode is an act of blocking the transmission of uplink service data in the inactive state.

The specific blocking of uplink service data transmission is reflected in: if the terminal needs to send uplink service data, it needs to send a recovery request to the network (the network includes but is not limited to the base station), and the terminal will be suspended after forming the recovery request, and only the recovery request is suspended. After the start state is released, it can be sent normally.

In some embodiments of the present disclosure, when the uplink service data of the UE arrives, the resume (Resume) request is triggered and it is in the pending state (Pending); based on the duration of the suspension timer, it is determined whether to continue to send the Resume request message to the base station through the air interface. ; The main work steps are as follows:

The Tpengding duration is notified to the user equipment (User Equipment, UE) by the network through a dedicated signaling or a broadcast message, or pre-determined by agreement. The UE here is the aforementioned terminal.

After the Resume request is triggered, it is in the pending state (Pending), that is, the Tpengding timer is started.

After the Tpengding timer expires, if the paging message (RAN paging) sent by the network is not received, the suspended Resume request is unsuspended, that is, the Resume request.

Tpengding duration can be configured as infinite.

Before the Tpengding timer expires, if a paging message (RAN paging) sent by the network is received, the Tpengding timer is stopped, the suspended Resume request is unsuspended, and the Resume request message is continued to be sent to the base station through the air interface.

As an embodiment, the reason for the call establishment in the Resume request is the call origination (Mobile Original, MO).

As an embodiment, the reason for call establishment in the Resume request is to receive a call (Mobile Terminal, MT).

When the user equipment (User Equipment, UE) uplink service data arrives, the Resume request is triggered and it is in the pending state (Pending); until the RAN paging message is received, the Resume request message is sent to the base station on the air interface. ; The main work steps are as follows.

As an embodiment, the reason for call establishment in the Resume request is MO

As an embodiment, the reason for call establishment in the Resume request is MT;

In one embodiment, the network knows the location of the UE through RNAU initiated by the UE.

The UE periodic radio network notification area update (Radio Notification Area Update, RNAU) or the RNAU process triggered by the UE RNA change. The resume request initiated in the RNAU process initiated by the UE is not restricted by the aforementioned suspension mechanism. The suspension mechanism here is: the resume request enters the suspended state after being formed in the terminal, and the state of the reply request that can be sent after the suspended state is based.

That is, the resume request for RNAU is sent directly once it is formed, instead of entering the suspended state first, and then sending it after waiting for the suspended state to be lifted.

When the inactive state of the downlink mode and the inactive state of the normal mode are parallel, the network decides whether to let the UE enter the inactive state of the downlink only mode from the connected state or the normal state (Normal) based on the type of the terminal or the UE capability Inactive state.

Switch from connected state to Downlink only RRC-INACTIVE: Through the RRC connection release message, the message indicates that the UE enters Downlink only RRC-INACTIVE.

In an embodiment, if the inactive state of the downlink-only mode is a sub-state of the inactive state of the normal mode (Normal), the network allows the UE to be in the inactive state of the uplink-only mode based on the type of the terminal or the UE capability. Or switch between the inactive state of Normal.

Switch from connected state to Downlink only RRC-INACTIVE: Through the RRC connection release message, the message indicates that the UE enters RRC-INACTIVE. Then the network informs the UE to switch between the inactive state of Downlink only RRC-INACTIVE and Normal through MAC CE or DCI.

In some cases, the UE automatically enters Downlink only RRC-INACTIVE after the timer T1 expires. The timing T1 here may be the aforementioned second timing.

In some cases, the UE counts the number of Resume requests triggered by uplink service data within a period of time (T). If the number of Resume requests triggered by uplink service data is less than a certain threshold, it will automatically enter Downlink only RRC-INACTIVE.

It is worth noting that the above timers and thresholds can be notified to the user by the network or agreed in advance by agreement.

In some implementations, only the inactive state and the connected state or the idle state of the downlink mode are converted.

The handover from Downlink only RRC-INACTIVE to connected state may include: the UE initiates a Resume request.

Downlink only switching from RRC-INACTIVE to idle state may include: the network sends a release message to let the UE enter the idle state.

In some embodiments, the UE may send auxiliary information to inform the network whether it wants to enter the inactive state of downlink only mode or the inactive state of Normal.

The auxiliary information can be carried in the recovery request, or sent in any situation when the terminal is in the connected state.
