The steps of the present disclosure are not limited to all of these numbering steps, i.e., the steps may be combined in any way to form different embodiments.

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

s110: entering a non-activated state of a downlink mode; in the inactive state of the downlink mode, the terminal can receive downlink service data.

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

reception antennas (RX) decrease from 4 to 2 or 1 for R15; the lightweight terminal has fewer receiving antennas than an eMBB terminal supporting an eMBB service.

Bandwidth reduction, typical values for FR1 are 5MHz/10MHz, while typical values for FR2 are 40MHz; the lightweight terminals are smaller than the bandwidths supported by the eMBB terminals.

The processing capacity decreases; smaller transport block (Transmission Block, TB) sizes (sizes) and downlink control information (Dwonlink Control Information, DCI) sizes (sizes) may be supported; for example, the processing power of the CPU of the lightweight terminal is greater than the processing power of the CPU of the emmbb, including but 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 lightweight terminal may be a fixed terminal or a terminal with a relatively small range of movement.

In the embodiment of the present disclosure, a new terminal state is provided, that is, a non-active state of a downlink mode of a terminal.

Here, the inactive state of the downlink mode may be referred to as the inactive state of the downlink mode only, and the corresponding shall be: downlink only RRC-INACTIVE.

When the terminal is in the inactive state of the downlink mode, the downlink service data reception of the terminal is allowed. Here, the downlink service data reception includes: and receiving downlink service data.

In this state, the terminal may only turn on the reception processing path in the terminal, i.e., the terminal may turn off the transmission signal processing path (i.e., the uplink signal processing path), thereby reducing power consumption generated when the transmission link is in an on state. And because the receiving link of the terminal is opened, 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 such a downlink mode may be a terminal type that is significantly highlighted for downlink traffic data reception. For example, a type of terminal in which a difference between a downlink traffic data reception amount and an uplink traffic data transmission amount is greater than a difference threshold.

Terminals of this type include, but are not limited to, tracking and locating terminals. Typical tracking and locating terminals include, but are not limited to: a navigation device. The navigation device includes, but is not limited to: a car navigation device and/or a person navigation device.

Because the downlink service data of the terminal is relatively more, the uplink service data is relatively less, and the downlink service data of the terminal in the inactive state of the downlink mode is not blocked from being received, so that the timeliness of the downlink service data reception can be ensured. Meanwhile, the uplink service data transmission is blocked, so that the phenomenon that the terminal only has a small amount of uplink service data, and the state switching or the transmission is performed, so that the uplink service data is frequently transmitted and/or the state switching is frequent can be reduced.

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

Because the transmission of the uplink service data of the terminal is blocked, the terminal can close the transmission of the uplink service data, thereby reducing the power consumption of the terminal as much as possible. The blocking of uplink traffic data does not represent a blocking of uplink signaling. For example, the uplink signaling can be normally sent, so that the interaction between the terminal and the base station through the uplink signaling is facilitated, and the state switching of the terminal is realized.

In some embodiments, as shown in fig. 3, the method further comprises:

s120: and determining a recovery request for sending the uplink service data by the terminal in the inactive state of the downlink mode.

The recovery request is used for sending the uplink service data, and comprises the following steps: the recovery request is used for requesting to send uplink service data, or the recovery request carries a smaller amount of uplink service data. The recovery request itself carries a smaller amount of uplink traffic data, which may include the request information and/or the uplink traffic data.

For example, the forming the recovery request includes:

s120: determining a recovery request in response to the uplink traffic data transmission; wherein the resume request is for requesting a resume to a connected state or any other appropriate state. Any other suitable state herein includes, but is not limited to: a connected state or an inactive state of the normal mode.

If the terminal is in the inactive state of the downlink mode, the terminal can send a recovery request to the base station to request to recover to the connected state if the terminal has uplink service data to send. The terminal returns to the connected state and the base station establishes an RRC connection with the terminal, which may be used to transmit control commands and/or data.

Notably, are: the determining a resume request here includes: a recovery request is formed in the terminal, for example, according to the information format of the recovery request, a recovery request to be transmitted is generated.

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

In some embodiments, as shown in fig. 4, the method further comprises:

s130: in response to determining the resume request, a suspended state of the resume request is entered.

In some embodiments, after entering the suspend state, waiting for the suspend state to unlock; if unlocked, a certain resume request is sent.

In other embodiments, in the suspended state, the paging message sent by the base station is awaited for reception. The paging message may be used to unlock the suspended state.

In response to sending the resume request, the terminal may enter a suspended state of the resume request. In the suspended state, the terminal waits for a paging message transmitted from the base station. If the paging message is received, the terminal establishes RRC connection with the base station, so that the terminal is switched from the inactive state of the downlink mode to the connected state.

After entering the connected state, the uplink traffic data can be transmitted through the RRC connection.

In some embodiments, the method further comprises:

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

and maintaining the suspension state in the timing time of the first timer.

Starting a first timer when entering a suspension state; the suspended state is maintained for the timing time of the first timer. The first timer times out and exits the suspended state.

In all embodiments of the present disclosure, the terminal may be maintained in the suspended state until the first timer does not overflow. In all embodiments of the present disclosure, the terminal may exit the suspended state when the first timer overflows.

In all embodiments of the present disclosure, the terminal may exit the suspended state when receiving the paging message; namely: the terminal exits the suspended state in response to receiving the paging message, whether or not the first timer overflows.

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

Once the terminal enters a suspended state, the terminal can be considered to suspend uplink transmission; during this period, the terminal can close the uplink signal processing path in the terminal, further reducing the power consumption in the terminal.

In some embodiments, the method further comprises:

and when the suspension state releasing condition is satisfied, releasing the suspension state.

There are various cases in which the release condition of the suspended state is satisfied, and two alternative ways are provided below:

mode one:

in response to the first timer expiring, the suspended state is released. The first timer may also be referred to as a suspend state timer, and is a timer for timing the terminal to enter the suspend state according to the trigger of the resume request.

Mode two:

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

And if the first timer is within the timing time of the first timer, namely the first timer is not overtime 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, the first timer is reset in response to receiving the paging message or in response to exiting the suspended state.

After the suspension state is released, the terminal may also continue with the transmission of a resume request.

In some embodiments, the method further comprises:

receiving the time length information of the first timer;

Or alternatively, the process may be performed,

and determining the duration information of the first timer according to a protocol.

In all embodiments of the present disclosure, the duration information of the first timer may be sent in advance by the base station, for example, by a system message (System Information, SI). Still further, the timing information may be sent by a broadcast system message or by a request message of an on-demand system message of the terminal, at which time the terminal may send the timing information by a system message unicast to a 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 specifications of the protocol; or the base station and the terminal are determined after negotiation; or determined based on parameters uploaded by the terminal.

The duration information at least comprises: the timing time length information of the timer is used for indicating the timing time length of the timer.

In one embodiment, the timing time length information of the timer may be infinitely long.

In another embodiment, the timing time length information of the timer may be the time from the time of determining the resume request to the time being paged based on the statistics. That is, the timing time length information of the timer is determined according to the history time length of determining the time from the resume request to the 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 one embodiment, the first timer may not be set in the terminal, and the terminal may exit the suspended state or the inactive state of the downlink mode only when receiving the paging information.

When the timing duration of the first timer is not infinitely long, the terminal is automatically released from the suspension state, so that the time for the terminal to wait for the base station to send the paging message is released, and the infinitely waiting for the paging message of the terminal is reduced.

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

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

receiving the time length information of the first timer sent by downlink signaling;

or alternatively, the process may be performed,

and receiving the duration information of the first timer, which is sent by system message broadcasting.

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

The downlink signaling includes, but is not limited to, RRC signaling. The time length information of the first timer is sent through the RRC signaling in a unicast mode, so that the time length 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, e.g. by a system message (System Information, SI).

In another embodiment, the system message is sent using a broadcast or based on a request message from a terminal on-demand system message. At this time, the terminal may transmit the timing information through a system message unicast to a 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 specifications of the protocol; or the base station and the terminal are determined after negotiation; or determined based on parameters uploaded by the terminal; or the terminal determines itself.

In all embodiments of the present disclosure, if there are multiple terminals with the same terminal or terminals with the same service requirement in the cell, the duration information of the first timer may be broadcast through the system message, so that the multiple terminals can simultaneously receive the duration information in the broadcasted system message, thereby reducing signaling overhead of the base station.

In all embodiments of the present disclosure, it may be determined whether the terminal receives the duration information of the system message broadcast first timer by grouping the terminals; or determining whether the terminal applies the duration information of the first timer broadcast by the system message by grouping the terminals. That is, in some embodiments, the duration information of the first timer may be carried in a multicast message sent by multicast.

In some embodiments, the identity of the UE packet may be added to the system message.

In all embodiments of the present disclosure, terminal grouping may be performed according to terminal parameters indicating a type of terminal, a transmission capability of the terminal, and/or a codec capability of the terminal.

In some embodiments, as shown in fig. 4, the method further comprises:

s140: the resume request is sent in response to the suspended state being released or in response to an inactive state exiting the downstream mode.

If the suspended state is released, the terminal may transmit a determined resume request. Of course, the terminal may buffer the uplink service data to be reported first according to the requirement if the suspension state is released, and suspend the sending of the resume request.

In some embodiments, the resume request carries a call cause;

the call causes include: an originating call (MO) and/or a receiving call (Mobile Terminated, MT).

The uplink service data transmission may be because of uplink service data transmission in the calling process and uplink service data transmission in the called process.

In still other embodiments, the recovery request may carry uplink service data that needs to be reported to the base station, or uplink service data that is transmitted by the base station to the receiving end. If the recovery request directly carries the uplink service data, the data size of the uplink service data is usually smaller, for example, smaller than the data size threshold.

In some embodiments, the method further comprises:

receiving a status indication after the restoration request is sent; the state indication is used for indicating the state of the terminal.

The status indication may instruct the terminal to enter any state, including, for example, but not limited to:

a connected state, an idle state, a normal mode inactive state, or a downlink mode inactive state.

For example, the base station may determine the state that the terminal needs to enter according to any one or more of the type of the terminal, the capability of the terminal, the downlink service data that the base station needs to send to the terminal currently, and the data that needs to be received from the terminal, and then inform the terminal through the state indication.

The status indication may be sent by the base station after receiving a recovery request reported by the terminal, e.g. via a physical downlink control channel (Physical Dwonlink Control Channel, PDCCH) to the terminal.

After receiving the status indication, the terminal enters a status corresponding to the status indication. If the state corresponding to the state indication is different from the current state of the terminal, the terminal can perform state switching, and if the state indicated by the state indication is the current state of the terminal, the terminal maintains the current state.

In some embodiments, the method further comprises:

and after switching to a connection state according to the state indication, sending the uplink service data.

If the data size of the uplink service data to be sent by the terminal is larger, for example, the data size is larger than the data size which can be carried by the recovery request, the terminal can request to send the uplink service data after entering the connection state. At this time, after receiving a recovery request that does not carry uplink service data, or a recovery request that carries request information for entering a connection state, the base station may send a state indication for entering the connection state to the terminal.

After receiving the indication, the terminal enters a connection state, and reports the uplink service data to the base station after entering the connection state.

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

and responding to the recovery request carrying uplink service data, and determining that the terminal is in an inactive state of the downlink mode, an inactive state of the normal mode or an idle state according to the state indication.

If the data size of the uplink service data to be sent by the terminal is small, the data size can be carried in one or more recovery requests, and the recovery requests can also be utilized to directly carry the uplink service data. In this way, the base station receives the connection instruction sent after the recovery request, and can instruct the terminal to continuously maintain in the inactive state of the downlink mode, enter the inactive state of the normal mode or enter the idle state. Of course, the base station may also control the terminal to enter a connection state according to one or more of the communication requirement between itself and the terminal, the type of the terminal, and the communication capability of the terminal; at this time, the connection instruction may also instruct the terminal to enter the connection state.

In the disclosed embodiment, the status indication may be a semi-static control instruction that is sent on a semi-static cycle basis.

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

In some embodiments, the method further comprises:

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

or alternatively, the process may be performed,

and responding to the wireless network notification area change of the terminal by the inactive terminal in the downlink mode, and carrying out RNAU.

In the inactive state of the downlink mode, the terminal may perform the RNAU normally, i.e. the RNAU of the terminal is not affected by the aforementioned suspension state.

The terminal performing RANU may include: determining a recovery request; the resume request is not affected by the formation of the suspended state after being determined. I.e. in response to a resume request due to the determination of the RNAU, can be sent directly once determined without being blocked in the terminal waiting for the release of the suspended state.

In some embodiments, the inactive state of the downstream 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, and 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 comprises:

receiving a connection release message in response to being in a connected state;

the inactive state of entering the downlink mode includes:

and responding to the connection release message carrying indication information for indicating the inactive state entering the downlink mode, exiting the connection state and entering 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, i.e. the inactive state of the downlink mode is a parallel state with the inactive state of the normal mode, the base station may directly instruct the terminal to enter the inactive state of the downlink mode.

Therefore, when the base station instructs the terminal to release the connection, the base station 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 carries indication information indicating the inactive state of entering the downlink mode. The terminal can 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 an inactive state of the normal mode, and can enter an inactive state of the downlink mode based on a trigger event.

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

inactive state of downlink mode;

inactive state of normal mode; the inactive state of the normal mode is referred to as inactive state in the related art (also referred to as RRC inactive state).

In some embodiments, the method further comprises:

responding to the connection release message carrying the indication information of the inactive state entering the normal mode, exiting the connection state and entering the inactive state of the normal mode;

the inactive state of entering the downlink mode includes:

and in response to an event-based trigger, entering the inactive state of the downlink mode from the inactive state of the regular mode.

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

responsive to receiving an indication information entry indicating entry from an inactive state of the regular mode into an inactive state of the downlink mode in the inactive state of the regular mode, exiting the inactive state of the regular mode into the inactive state of the downlink mode;

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

and responding to the fact that the sending times of the recovery request triggered by the uplink service data in a preset time interval are lower than a threshold value, and exiting the inactive state of the normal mode to enter the inactive state of the downlink mode. The preset time interval may be set arbitrarily, which is not limited by the embodiment of the present disclosure. For example, the preset time interval may be one time interval before the current time.

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 normal mode, the base station will instruct the terminal to enter the inactive state of the normal mode. The terminal further enters a special state in the inactive state of the downlink mode, i.e. in the inactive state of the normal mode from the inactive state of the normal mode in response to the event: inactive state of the downlink mode.

For example, indication information of a base station is received. The indication information may be information dynamically transmitted by the base station.

In some embodiments, the indication information is carried in a medium access control MAC control element CE; or, the indication information is carried in downlink control information DCI.

The indication information is sent through the MAC CE or DCI, and the method has the characteristics of high speed and small delay.

In other embodiments, the indication information may also be carried in an RRC message.

In some embodiments, the method further comprises:

in response to receiving a connection release message in the inactive state of the downlink mode, exiting the inactive state of the downlink mode into an idle state or any other suitable state.

In the embodiment of the disclosure, the connection release message may also trigger the terminal to exit from the inactive state of the downlink mode and directly enter into the idle state with low power consumption or any other appropriate state.

For example, if the downlink data sent by the base station to the terminal is sent out, in order to further reduce the power consumption of the terminal, a connection release message may be sent to the terminal, so as to prompt the terminal to enter an idle state or any other appropriate state from the inactive state of the downlink mode.

Any other suitable state herein includes, but is not limited to: a connected state and/or an inactive state of the normal mode.

In some embodiments, the method further comprises:

reporting auxiliary information, wherein the auxiliary information comprises: and suggesting information for suggesting the terminal to enter the inactive state of the downlink mode or the inactive state of the normal mode.

The auxiliary information may be carried in the recovery request or may be reported separately. For example, when the terminal is in a connected state, the terminal may report in advance that the terminal is in an inactive state of a downlink mode, and if the terminal expects to enter a specific state after sending a recovery request, the expected specific state or a state in which entry is proposed may be carried by the auxiliary information.

As shown in fig. 5, an embodiment of the present disclosure provides a terminal state switching control method, including:

s210: and sending a control signaling for indicating the sending terminal to enter a non-activated state of a downlink mode, wherein the terminal can receive downlink service data in the non-activated state of the downlink mode.

The terminal switching control method can be applied to the base station. The control signaling here includes: and various downlink control signaling sent by the base station.

The base station can control the terminal to enter the inactive state of the downlink mode through various downlink control signaling. The inactive state of the downlink mode herein is a mode in which the terminal can receive downlink service data, and is a mode in which the inactive state of the normal mode is distinguished.

The downlink control signaling may be any type of signaling, including but not limited to: DCI or MAC CE or RRC message.

In the inactive state of the downlink mode, the uplink service data transmission of the terminal is blocked, so that the transmission of the uplink service data is always initiated frequently by the terminal because of a small amount of uplink service data generated by different times is reduced, and unnecessary uplink service data transmission of the terminal is reduced.

In some embodiments, as shown in fig. 6, the method further comprises:

s220: and receiving a recovery request sent by the terminal and used for requesting uplink service data transmission.

In the embodiment of the disclosure, a terminal in a non-active state of a downlink mode determines a recovery request in uplink service data to be transmitted, and enters a suspension state of the recovery request; in response to the suspension state being released, the terminal transmits the resume request to the base station.

In some embodiments, the method comprises:

sending a paging message, wherein the paging message is used for relieving a suspension state of a recovery request of the terminal for uplink service data transmission; or, the paging message is used for indicating that data to be sent to the terminal is received from the core network or the paging message is used for indicating the terminal to exit from the inactive state of the downlink mode.

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

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

But in response to receiving downlink traffic data or other trigger events from the core network to the terminal, the base station sends the paging message to the terminal, which may also be used to trigger the terminal to exit the suspended state or to exit the inactive state of the downlink mode, or the paging message may also be used simply to page the UE.

In one embodiment, the paging message herein may be a paging message sent by the base station according to whether there is a paging demand, and may not be sent for canceling the suspension state of the in-terminal resume request. 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 may trigger the terminal to release the suspended state of the resume request or the inactive state of the downlink mode.

In some embodiments, the method further comprises:

receiving a recovery request sent after the suspension state is released;

and sending a state indication in response to receiving the recovery request, wherein the state indication is used for indicating the state of the terminal.

If the terminal forms a recovery request when uplink service data to be sent exist, the terminal enters a suspension state. After the suspension state is released, the terminal transmits the resume request, and thus the base station receives the resume request.

According to the recovery request, the base station may transmit the status indication according to one or more of a type of the terminal, a transceiving capability of the terminal, a load of the base station itself, a wireless environment, and the like. The status indication may include one or more bits that may be used to indicate the status entered by the terminal, including but not limited to: a connected state, an idle state, a normal mode inactive state, or a downlink mode inactive state.

In some embodiments, the method further comprises: responding to the uplink service data sent when the state indication terminal enters a connection state; or, receiving the uplink service data carried by the recovery request.

The uplink service data to be sent by the terminal may be sent after the terminal enters a connection state after the recovery request is sent, or may be directly carried in the recovery request and reported to the base station when the amount of the uplink service data to be sent by the terminal is relatively small.

In some embodiments, the method further comprises: and sending the duration information of the first timer.

The first timer is a timer for counting the time when the terminal is in the suspended state. In all embodiments of the present disclosure, the duration information of the first timer may be sent by the base station or may be specified by a communication protocol.

In all embodiments of the present disclosure, the duration information of the first timer may be sent in advance by the base station, for example, by a system message (System Information, SI). Still further, the timing information may be sent by a broadcast system message or by a request message of an on-demand system message of the terminal, at which time the terminal may send the timing information by a system message unicast to a 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 specifications of the protocol; or the base station and the terminal are determined after negotiation; or determined based on parameters uploaded by the terminal; or the terminal determines itself.

In one embodiment, the timing time length information of the timer may be infinitely long. In another embodiment, the timing time length information of the timer may be determined based on statistically determined times to resume the request to be paged. That is, the timing time length information of the timer is determined according to the history time length of determining the time from the resume request to the 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.

Transmission in some embodiments, the duration information is determined based on protocol specifications.

In some embodiments, the sending the duration information of the first timer includes:

the time length information of the first timer is sent through signaling;

or alternatively, the process may be performed,

and the duration information of the first timer is broadcasted through a system message.

The base station can broadcast the timing information of the first timer through a system message, and can also send the timing information to the terminal through signaling unicast. Signaling here includes, but is not limited to: RRC message or on-demand based SI. The base station can determine whether to transmit the timing information of the first timer in a broadcast mode or in a unicast mode of signaling according to the number of terminals which need to receive the timing information and the like.

In other embodiments, if the terminals are grouped, the terminal group including the plurality of terminals may also send the timing information of the first timer in a multicast manner. In all embodiments of the present disclosure, terminal grouping may be performed according to the type of terminal, UE capabilities of the terminal, parameters of the terminal.

At this time, the sending the control signaling triggering the terminal to enter the inactive state of the downlink mode includes:

receiving a connection release message; the connection release message carries indication information indicating that the terminal enters the inactive state of the downlink mode.

If the current terminal is in the inactive state of the downlink mode, the base station may send a connection release message, where the connection release message carries indication information indicating that the terminal enters the inactive state of the downlink mode, and after receiving the connection release message, the terminal exits the current state, for example, the connection state or the idle state, and enters 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 belongs to a sub-mode of the inactive state of the normal mode, at the moment, the inactive state of the downlink mode needs to be entered, and the inactive state of the normal mode needs to be entered first; and then enters the inactive state of the downlink mode from the inactive state of the normal mode. In view of this, the sending the control signaling triggering the terminal to enter the inactive state of the downlink mode includes:

receiving a connection release message in response to the terminal being in a connected state or an idle state; the connection release message carries indication information for indicating the terminal to enter the inactive state of the normal mode; and the terminal enters the inactive state of the downlink mode from the inactive state of the normal mode based on an event triggering event.

At this time, the terminal receives the connection release message, and then enters the inactive state of the normal mode, monitors whether an event occurs at the terminal, and if so, enters the inactive state of the downlink mode from the inactive state of the normal mode under the triggering of the event.

In all embodiments of the present disclosure, in response to the terminal being in an inactive state in the normal mode, the method includes:

And responding to a trigger event, and enabling the terminal to enter the inactive state of the downlink mode from the inactive state of the normal mode.

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

responsive to receiving, in an inactive state of the regular mode, indication information indicating entry from the inactive state of the regular mode to an inactive state of a downlink mode, exiting the inactive state of the regular mode to the inactive state of the downlink mode;

responsive to a second timer timeout in an inactive state associated with the regular mode, exiting the inactive state of the regular mode into an inactive state of the downlink mode;

In all embodiments of the present disclosure, a terminal in an inactive state of a normal mode may be capable of entering the inactive state of a downlink mode based on a control signaling sent by a base station to trigger the terminal to enter the inactive state of the downlink mode. Namely:

and sending indication information for indicating the inactive state of entering the downlink mode from the inactive state of the normal mode.

In all embodiments of the present disclosure, even if the terminal is in a connected state or an idle state, the terminal may enter an inactive state of a normal mode by the indication information and then enter an inactive state of a downlink mode. In all embodiments of the present disclosure, the terminal may be in an inactive state of entering the normal mode according to the connection release message, and enter the inactive state of the downlink mode according to the indication information.

In order to control the terminal to maintain the inactive state of the normal mode, the terminal is controlled to switch between various states more precisely.

In the embodiment of the disclosure, the base station transmits the indication information through the MAC CE or DCI, and has the characteristics of large transmission flexibility and small delay.

In some embodiments, the method further comprises:

and sending a connection release message, wherein the connection release message is used for triggering the terminal to exit the inactive state of the downlink mode and enter an idle state.

If the current terminal is in the inactive state of the downlink mode, the terminal can be triggered to enter an idle state which saves more power consumption by sending a connection release message, so that the terminal completely releases the RRC connection with the base station.

In all embodiments of the present disclosure, the connection release message indicating that the terminal enters the idle state from the inactive state of the downlink mode may be the same or different from the connection release message indicating that the terminal enters the inactive state of the normal mode from the connected state.

In some embodiments, the method further comprises:

receiving auxiliary information, wherein the auxiliary information comprises: and suggesting information for suggesting the terminal to enter the inactive state of the downlink mode or the inactive state of the normal mode.

The auxiliary information may be carried in the resume request or in any information of the independent resume request, for example, upstream control information (Uplink Control Information, UCI).

A specific example is provided below in connection with any of the embodiments described above:

The inactive state of the normal mode is a working mode which is more suitable for the terminal of the internet of things. The inactive state of the normal mode herein may be an inactive state in the related art or an RRC inactive state.

But there are often special requirements for many internet of things devices. For example, some devices of the internet of things only have downlink transmission requirements, such as tracking and positioning terminals, and do not need an independent uplink mode, i.e. uplink service data transmission only needs to be performed after downlink transmission. Therefore, the working mode of the internet of things equipment working in the inactive state can be optimized.

Introducing a downlink-only INACTIVE state (Downlink only RRC-INACTIVE);

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 operates independently of the inactive state.

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

The specific blocking uplink service data transmission is shown in the following steps: if the terminal needs to send uplink service data, a recovery request needs to be sent to a network (including but not limited to a base station), and the terminal is suspended after forming the recovery request, only after the suspension state of the recovery request is released, the terminal can normally send the recovery request.

In some embodiments of the present disclosure, when uplink traffic data of the UE arrives, a Resume request is triggered to be in a Pending state (Pending); deciding whether to continue to send a Resume request message to the base station on the air interface based on the duration of the suspension timer; the main working steps are as follows:

the tpengaging duration is a duration that the network notifies User Equipment (UE) through dedicated signaling or broadcast message, or is specified by a predetermined protocol. The UE here is the aforementioned terminal.

The Resume request is triggered to be in a Pending state (Pending), i.e. a tpengaging timer is started.

After the tpengaging timer expires, if no paging message (RAN paging) sent by the network is received, the suspended Resume request is released, i.e., the Resume request.

The tpengaging duration may be configured as an infinite length (infinite).

Before the tpengaging timer times out, if a paging message (RAN paging) sent by the network is received, the tpengaging timer is stopped, the suspended Resume request is released, and a Resume request message is continuously sent to the base station through an air interface.

As an example, the call setup in the Resume request is due to the originating call (MO).

As an example, the call setup in the Resume request is due to a received call (MT).

When uplink service data of User Equipment (UE) arrives, a Resume request is triggered and then is in a Pending state (Pending); until receiving RAN paging (paging) message, continuing to send a Resume request message to the base station through an air interface; the main working steps are as follows.

As one example, the call setup in the Resume request is due to MO

As an example, the call setup in the Resume request is due to MT;

in one embodiment, the network knows the location of the UE through the UE-initiated RNAU.

The UE periodically radio network informs of zone updates (Radio Notification Area Update, RNAU) or UE RNA change triggered RNAU procedures. The resume request initiated in the UE-initiated RNAU procedure is not limited by the suspension mechanism described above. The suspension mechanism here is: the recovery request is first put into a suspended state after being formed in the terminal, and the suspended state is a state of the recovery request which can be transmitted after being based.

I.e. the recovery request for the RNAU is sent directly once formed, rather than first entering the suspended state, waiting to be sent after the suspended state is released.

In a mode in which the inactive state of the downlink mode and the inactive state of the Normal mode are parallel, the network decides whether to allow the UE to enter the inactive state of the downlink-only mode or the inactive state of the Normal mode from the connected state based on the type of the terminal or the UE capability.

Switching from connected state to Downlink only RRC-INACTIVE: the UE is indicated in the message to enter Downlink only RRC-INACTIVE by RRC connection release message.

In one embodiment, if the inactive state of the downlink-only mode is one of the sub-states of the inactive state of the Normal mode (Normal), the network switches the UE between the inactive state of the uplink-only mode or the inactive state of the Normal based on the type of terminal or UE capability.

Switching from connected state to Downlink only RRC-INACTIVE: the UE is indicated to enter RRC-INACTIVE in the message via an RRC connection release message. The network then informs the UE, either by MAC CE or DCI, to switch between the Downlink only RRC-INACTIVE and Normal INACTIVE states.

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 still other cases, the UE counts the number of requests to initiate uplink traffic data triggers for a period of time (T) and automatically enters Downlink only RRC-INACTIVE if the number of requests to initiate uplink traffic data triggers is less than a threshold.

Notably, the above timer and threshold may be a network notification to a user or a pre-protocol agreement.

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

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

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

In some embodiments, the UE may send assistance information to the network informing whether it is desired to enter the inactive state of the downlink only mode or the inactive state of Normal.

The auxiliary information may be carried in the resume request or transmitted in any situation where the terminal is in a connected state.
