It is not limited in the embodiments of the present disclosure that these numbered steps all have to be performed, i.e., that these steps can 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 an inactive state of a downlink mode; and the terminal can receive downlink service data in the inactive state of the downlink mode.

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

receive antenna (RX) reduction from 4 of R15 to 2 or 1; the light terminal has fewer receiving antennas than an eBB terminal supporting an eBB service.

The bandwidth is reduced, typical values for FR1 are 5MHz/10MHz, and typical values for FR2 are 40 MHz; the lightweight terminal supports less bandwidth than an eMBB terminal.

The processing capacity is reduced; a smaller Transport Block (TB) size (size) and Downlink Control Information (DCI) size (size) may be supported; for example, the processing capability of the CPU of the lightweight terminal is greater than that of the eMBB, including but not limited to: the decoding rate is lower than the decoding rate of the eMBB terminal and/or the coding rate is lower than the coding 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 proposed, which is an inactive state of a downlink mode of a terminal.

The inactive state of the downlink mode may also be referred to as an inactive state of the downlink-only mode, and may 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 traffic data reception includes: and receiving downlink service data.

In this state, the terminal may only turn on the reception processing path within the terminal, that is, the terminal may turn off the transmission signal processing path (i.e., 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 the downlink mode may be a terminal type that is significantly outstanding for the received amount of downlink traffic data. For example, the type terminal in which the difference between the downlink traffic data reception amount and the uplink traffic data transmission amount is greater than the difference threshold value.

This type of terminal includes, but is not limited to, a track and locate type terminal. Typical track-and-locate type terminals include, but are not limited to: a navigation device. The navigation device includes but is not limited to: the vehicle-mounted navigation equipment and/or the man-carried navigation equipment.

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

In some embodiments, in the 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 the uplink traffic data does not represent a blocking of the uplink signaling. 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. 3, the method further comprises:

s120: the terminal in the inactive state of the downlink mode determines a recovery request for transmitting 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 carries a smaller amount of uplink service data. The recovery request itself carries a small amount of uplink service data, that is, the recovery request may include request information and/or uplink service data.

For example, the forming a recovery request includes:

s120: responding to the transmission of the uplink service data, and determining a recovery request; wherein the recovery request is for requesting recovery to a connected state or any other appropriate state. Any other appropriate state herein includes, but is not limited to: connected state or inactive state of 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 can send a recovery request to the base station to request to recover to the connected state. The terminal returns to the connected state and the base station establishes an RRC connection with the terminal, which can be used for transmitting control commands and/or data.

It is worth noting that: determining a recovery request here includes: the recovery request is formed in the terminal, for example, the recovery request to be sent is generated according to the information format of the recovery request.

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, entering a suspend state for the resume request.

In some embodiments, after entering the suspend state, wait for the suspend state to unlock; if unlocked, a deterministic recovery request is sent.

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

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

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

In some embodiments, the method further comprises:

in response to entering the suspend state, starting a first timer;

maintaining the suspend state during a timing time of the first timer.

Starting a first timer when entering a suspended state; during the timing time of the first timer, the suspend state is maintained. The first timer expires and the suspend state is exited.

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

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

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

Once the terminal enters the suspension state, the terminal can be considered to suspend uplink transmission; during the period, the terminal can close the uplink signal processing path in the terminal, and further reduces the power consumption in the terminal.

In some embodiments, the method further comprises:

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

There are many cases where the suspension state release condition is satisfied, and two alternative ways are provided as follows:

the first method is as follows:

in response to the first timer expiring, releasing the suspended state. The first timer may also be referred to as a suspend state timer, and is a timer for timing when the terminal enters the suspend state according to the recovery request.

The second method comprises the following steps:

in response to receiving a paging message, releasing the suspended state.

And if the first timer is within the timing time of the first timer, namely the first timer is not overtime and receives the paging message sent by the base station, the suspension state is released.

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

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

The terminal may also continue to transmit the resume request after the suspend state is released.

In some embodiments, the method further comprises:

receiving duration information of the first timer;

alternatively, the first and second electrodes may be,

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 by the base station in advance, for example, sent through a System Information (SI). And further, the timing information is sent by using a broadcast system message or a request message of the terminal on-demand system message, and at the moment, the terminal can send the timing information to the system message of a specific terminal through unicast according to the request message.

In all embodiments of the present disclosure, the duration information of the first timer may also be determined according to the specification of the protocol; or the base station and the terminal negotiate and then determine; or determined based on parameters uploaded by the terminal.

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

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

In another embodiment, the timing length information of the timer may be a time to page for a recovery request determined based on statistical data. That is, the timing time length information of the timer is determined according to the history time length of the time from the determination of the recovery 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 duration information of the first timer.

In one embodiment, the terminal may not set the first timer, and the terminal may exit the suspend 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 infinite, the terminal can automatically release 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 indefinite waiting time of the terminal for the paging message is reduced.

The above is merely an example of the suspended state 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 duration information of the first timer sent through downlink signaling;

alternatively, the first and second electrodes may be,

and receiving the duration information of the first timer 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 RRC signaling in a unicast mode, and 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, for example, sent by a System Information (SI).

In another embodiment, the system message is sent using a broadcast or request message based on the 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 specification of the protocol; or the base station and the terminal negotiate and then determine; or is determined based on parameters uploaded by the terminal; or the terminal may be self-determining.

In all embodiments of the present disclosure, if there are multiple terminals with the same service requirement or the same terminal 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 receive the duration information at the same time in the broadcast system message, thereby reducing the signaling overhead of the base station.

In all embodiments of the present disclosure, whether a terminal receives duration information of the system message broadcast first timer may be determined by grouping terminals; or determining whether the terminal broadcasts the duration information of the first timer by applying the system message in a grouping mode for the terminal. 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 identity of the UE group may be added in the system message.

In all embodiments of the present disclosure, terminal grouping may be performed according to terminal parameters indicating a type of the 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: sending the resume request in response to the suspend state being released or in response to exiting an inactive state of the downstream mode.

If the suspend state is released, the terminal may send a recovery request that has been determined. Certainly, the terminal may also buffer the uplink service data to be reported and suspend sending the resume request according to the requirement, if the suspend state is released.

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

the call reasons include: originating a call (MO) and/or receiving a call (MT).

The uplink service data transmission may be performed in the calling process or in the called process.

In some further embodiments, the recovery request may carry uplink service data that needs to be reported to the base station, or the uplink service data that is transmitted to the receiving end by the base station. If the recovery request directly carries the uplink service data, at this time, 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 recovery request is sent; and the state indication is used for indicating the state of the terminal.

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

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

For example, the base station may determine a state that the terminal needs to enter according to any one or more of the type of the terminal, the capability of the terminal, downlink service data that the base station needs to send to the terminal currently, and data that needs to be received from the terminal, and then notify 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, for example, sent to the terminal through a Physical Downlink Control Channel (PDCCH).

After receiving the status indication, the terminal enters a status corresponding to the status indication. And if the state corresponding to the state indication is different from the current state of the terminal, the terminal switches the state, 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 volume of the uplink service data to be sent by the terminal is relatively large, for example, greater than the data volume that can be carried by the recovery request, the terminal may request to enter a connected state and then send the uplink service data. At this time, after receiving a recovery request carrying no uplink service data or a recovery request carrying 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 connected state, and reports the uplink service data to the base station after entering the connected state.

In some embodiments, said performing a state switch according to said 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 a conventional mode or an idle state according to the state indication.

If the data amount of the uplink service data that the terminal needs to send is small and can be carried in one or more recovery requests, the uplink service data can also be directly carried by using the recovery requests. In this way, the connection indication sent by the base station after receiving the recovery request may indicate the terminal to continue to be maintained 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 and the like according to one or more conditions of communication requirements between the base station and the terminal, the type of the terminal, and the communication capability of the terminal; at this time, the connection indication may also indicate that the terminal enters a connected state.

In the disclosed embodiment, the status indication may be a semi-static control command, which is sent based on a semi-static period.

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

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;

alternatively, the first and second electrodes may be,

and the inactive state terminal in the downlink mode responds to the change of the wireless network notification area of the terminal to carry out the RNAU.

In the inactive state of the downlink mode, the terminal may normally perform an RNAU, that is, the RNAU of the terminal is not affected by the suspend state.

The terminal performing RANU may include: determining a recovery request; the resume request is determined to be unaffected by the formation of the suspend state. I.e. in response to a recovery request due to RNAU determination, can be sent directly upon determination without being blocked in the terminal waiting for the release of the suspended state.

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

The inactive state of the normal mode is different from the inactive state of the downstream mode, and a resume request formed in the inactive state of the normal mode does not trigger a suspend state of the resume request but is transmitted 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 entering of the inactive state of the downlink mode includes:

and exiting the connection state and entering the inactive state of the downlink mode in response to the connection release message carrying indication information indicating that the inactive state of the downlink mode is entered.

If the inactive state of the downlink mode is an inactive state independent 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 may directly instruct the terminal to enter the inactive state of the downlink mode.

Therefore, when the base station indicates the terminal to release the connection, the base station can directly indicate 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 that the terminal enters the inactive state of 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 conventional 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 conventional 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 the trigger event.

In this case, the inactive state includes one or more of the following specific examples:

an inactive state of the downlink mode;

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

In some embodiments, the method further comprises:

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

the entering of the inactive state of the downlink mode includes:

entering an inactive state of the downstream mode from an inactive state of the normal mode in response to an event-based trigger.

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 the trigger event. The triggering event includes at least one of:

in response to receiving an entry of indication information indicating an entry from an inactive state of the normal mode to an inactive state of a downlink mode in an inactive state of the normal mode, exiting the inactive state of the normal mode to enter the inactive state of the downlink mode;

responding to the timeout of a second timer in the inactive state of the conventional mode, exiting the inactive state of the conventional mode to enter the inactive state of the downlink mode;

and responding to the number of times of sending recovery requests triggered by the uplink service data in a preset time interval to be lower than a threshold value, and exiting the inactive state of the conventional mode to enter the inactive state of the downlink mode. The preset time interval may be set arbitrarily, and the embodiment of the present disclosure does not limit this. For example, the preset time interval may be a 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 of the inactive states belonging to the normal mode, the base station may first instruct the terminal to enter the inactive state of the normal mode. The terminal further responds to the event to enter the inactive state of the downlink mode, namely, the terminal enters a special state in the inactive state of the normal mode from the inactive state of the normal mode: inactive state of the downlink mode.

For example, indication information of the 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 the DCI, and the method has the characteristics of high speed and small time delay.

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

In some embodiments, the method further comprises:

and in response to receiving the connection release message in the inactive state of the downlink mode, exiting the inactive state of the downlink mode to enter an idle state or any other appropriate state.

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

For example, when the downlink service 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 cause 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 suggestion information for suggesting that the terminal enters 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 separately reported. For example, when the terminal is in the connected state, the terminal may report in advance that the terminal is in the inactive state of the downlink mode, and if the terminal expects to enter a specific state after sending the recovery request, the expected specific state or the state that the terminal proposes to enter 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, where the method includes:

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

The terminal switching control method can be applied to a 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. Here, the inactive state of the downlink mode is a mode in which the terminal can receive downlink service data, and is an inactive state that distinguishes a conventional mode.

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 which is always frequently initiated by the terminal due to a small amount of uplink service data generated by the terminal at different time is reduced, and the 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 which is sent by the terminal and used for requesting the transmission of the uplink service data.

In the embodiment of the present disclosure, a terminal in an inactive state in a downlink mode determines a resume request when uplink service data to be sent is received, and enters a suspend state of the resume request; in response to the suspend 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 releasing a suspension state of a recovery request of the terminal for sending uplink service data; or, the paging message is used to indicate that data to be sent to the terminal is received from a core network, or the paging message is used to indicate that the terminal exits from the inactive state of the downlink mode.

In response to receiving the resume 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 suspend state of the resume request of the terminal or 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.

However, in response to receiving downlink service data or other triggering events sent to the terminal from the core network, the base station sends the paging message to the terminal, and the paging message may also be used to trigger the terminal to exit from the suspend state or exit from the inactive state of the downlink mode, or the paging message may also be used to page the UE alone.

In one embodiment, the paging message may be a paging message that the base station transmits according to whether there is a paging requirement, and may not be transmitted for releasing the suspended state of the intra-terminal resume request. However, when the paging message is sent to the terminal, if the terminal has determined a resume request and the terminal is in a suspend state of the resume request or an inactive state of the downlink mode, the paging message may trigger the terminal to release the suspend 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 the uplink service data is to be sent, and enters a suspended state. After the suspend 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 the type of the terminal, the transceiving capability of the terminal, the load of the base station itself, and the wireless environment. The status indication may comprise 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, an inactive state of a normal mode, or an inactive state of a downlink mode.

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 that the terminal needs to send may be sent after entering a connected state after sending the recovery request, or may be directly carried in the recovery request and reported to the base station when the amount of the uplink service data that the terminal needs to send 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 by the base station in advance, for example, sent through a System Information (SI). And further, the timing information is sent by using a broadcast system message or a request message of the terminal on-demand system message, and at the moment, the terminal can send the timing information to the system message of a specific terminal through unicast according to the request message. In all embodiments of the present disclosure, the duration information of the first timer may also be determined according to the specification of the protocol; or the base station and the terminal negotiate and then determine; or is determined based on parameters uploaded by the terminal; or the terminal may be self-determining.

In one embodiment, the timing length information of the timer may be infinitely long. In another embodiment, the timing length of time information of the timer may be determined based on a statistical determination of the time until the recovery request is paged. That is, the timing time length information of the timer is determined according to the history time length of the time from the determination of the recovery 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 duration information of the first timer.

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

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

the duration information of the first timer is sent through signaling;

alternatively, the first and second electrodes may be,

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

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

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

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

receiving a connection release message; wherein, 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 from the current state, such as the connected 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 conventional mode, and the inactive state of the downlink mode needs to be entered at this time, the inactive state of the conventional 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 of the control signaling triggering the terminal to enter the inactive state of the downlink mode includes:

responding to the terminal in a connection state or an idle state, and receiving a connection release message; wherein, the connection release message carries indication information indicating that the terminal enters the inactive state of the normal mode; and the terminal enters the inactive state of the downlink mode from the inactive state of the conventional mode based on an event trigger event.

At this time, the terminal enters the inactive state of the normal mode after receiving the connection release message, monitors whether an event occurs at the terminal, and if the event occurs, enters the inactive state of the downlink mode from the inactive state of the normal mode under the trigger of the event.

In all embodiments of the present disclosure, in response to the terminal being in an inactive state of 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 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 the trigger event. Wherein the triggering event comprises at least one of:

in response to receiving indication information indicating that an inactive state of a downlink mode is entered from an inactive state of the normal mode in an inactive state of the normal mode, exiting the inactive state of the normal mode into the inactive state of the downlink mode;

in response to expiration of a second timer associated with the inactive state of the regular mode, exiting the inactive state of the regular mode into the inactive state of the downlink mode;

and responding to the number of times of sending recovery requests triggered by the uplink service data in a preset time interval to be lower than a threshold value, and exiting the inactive state of the conventional mode to enter the inactive state of the downlink mode. The preset time interval may be set arbitrarily, and the embodiment of the disclosure is not limited thereto. For example, the preset time interval may be a time interval before the current time.

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

and sending indication information indicating that the inactive state of the normal mode enters the inactive state of the downlink 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 the normal mode by the indication information and then enter an inactive state of the downlink mode. In all embodiments of the present disclosure, the terminal may enter the inactive state of the normal mode according to the connection release message, and enter the inactive state of the downlink mode according to the indication information.

To control the terminal to remain in the inactive state of the normal mode while more precisely controlling the terminal to switch between the various states.

In the embodiment of the present disclosure, the base station transmits the indication information through the MAC CE or the DCI, and has the characteristics of high 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 from 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 as 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 suggestion information for suggesting that the terminal enters 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 carried in any Information of the independent recovery request, for example, in Uplink Control Information (UCI).

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

the inactive state of the conventional 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 some special requirements for many internet of things devices. For example, some internet of things devices only have downlink transmission requirements, such as tracking and positioning terminals, and do not need an independent uplink mode, that is, transmission of uplink service data only needs to be performed after downlink transmission. Therefore, the working mode of the internet of things equipment working in the non-activated state can be optimized.

Introducing an INACTIVE state (Downlink only RRC-INACTIVE) of a 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 operates independently from the inactive state.

As an embodiment, the inactive state of the downlink mode is an act of blocking transmission of traffic-on-demand data.

The specific blocking of business data transmission is embodied as follows: if the terminal needs to send uplink service data, a recovery request needs to be sent to a network (the network includes but is not limited to a base station), the terminal is suspended after the recovery request is formed, and the terminal can normally send the uplink service data only after the suspended state of the recovery request is released.

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

the tpending duration is notified to the User Equipment (UE) by the network through dedicated signaling or broadcast message, or specified by a protocol in advance. The UE here is the aforementioned terminal.

The Resume request is triggered and then is in a suspended state (Pending), i.e. a tpending timer is started.

After the timeout of the tpeng timer, if a paging message (RAN paging) sent by the network is not received, the suspended Resume request is suspended, that is, the Resume request is released.

The Tpending duration may be configured to be infinite (infinite).

Before the Tpending timer is overtime, if a paging message (RAN paging) sent by a network is received, the Tpending timer is stopped, a suspend Resume request is released, and a Resume request message is continuously sent to an air interface to a base station.

As an example, the call establishment cause in the Resume request is an originating call (MO).

As an example, the call establishment cause in the Resume request is 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 message, continuing to send a Resume request message to the air interface to the base station; the main working steps are as follows.

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

As an example, the call establishment cause in the Resume request is MT;

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

UE periodic Radio Notification Area Update (RNAU) or RNAU flow triggered by UE rna change. The resume request initiated in the UE-initiated RNAU procedure is not limited by the aforementioned suspend mechanism. The suspend mechanism here is: the recovery request is first put into a suspended state after being formed in the terminal, and the recovery request is sent after the suspended state is established.

That is, the resume request to the RNAU is directly transmitted once formed, instead of entering the suspend state first and transmitting the resume request after the suspend state is released.

In a parallel mode of the inactive state of the downlink mode and the inactive state of the Normal mode, the network determines whether to let the UE enter the inactive state of the downlink-only mode or the inactive state of the Normal state (Normal) from the connected state based on the type of the terminal or the capability of the UE.

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

In one 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 switches the UE between the inactive state of the uplink-only mode and the inactive state of the Normal mode based on the type of the terminal or the capability of the UE.

Switching from connected state to Downlink only RRC-INACTIVE: the UE is indicated in the message to enter RRC-ACTIVE via an RRC connection Release message. Then the network informs the UE to switch between the INACTIVE states of Downlink only RRC-INACTIVE and Normal through a MAC CE or DCI mode.

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

In some other cases, the UE counts the number of times of initiating a Resume request triggered by uplink service data within a period of time (T), and if the number of times is less than a certain threshold, the UE automatically enters Downlink only RRC-INACTIVE.

It is noted that the above timers and thresholds may be network notification to the user or pre-agreed upon.

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

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

The switching of Downlink only RRC-INACTIVE to idle state 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 inform the network whether it wishes to enter an inactive state of downlink-only mode or a Normal inactive state.

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