Optionally, the satisfying conditions may include at least one of the following 1) to 13):

1) The terminal receives first downlink indication information.

The first downlink indication information is related to the energy saving function of the network side. Optionally, the first downlink indication information may be used to indicate at least one of the following: indicating that the network side device expects to enter the energy saving mode; instructing the terminal to perform an uplink transmission operation; instructing the network The side device expects to know the camping situation of the terminal in the cell and so on.

In this embodiment, the method may further include at least one of the following: a) the terminal receives a system message in the first cell, and the system message indicates that the first cell supports a network side energy saving function; b) The terminal receives energy-saving cell list information configured on the network side, and the energy-saving cell list information includes information about cells that support energy-saving functions on the network side; the terminal determines that the first cell supports network-side Energy saving function.

Optionally, the terminal may configure the energy-saving cell list information through a broadcast message or dedicated signaling (such as an RRC connection release message).

3) The uplink sending operation reaches a triggering moment, and the uplink sending operation is triggered periodically.

In this embodiment, the method further includes: the terminal acquires configuration information, and the configuration information includes at least one of the following: a) trigger time and repetition period of the uplink sending operation; b) periodic timer configuration, Wherein, in the case that the periodic timer is not running or times out, the terminal performs the uplink sending operation.

In one embodiment, the network side can indicate to the terminal the energy-saving pattern (time or duration, period, etc.) Before the time, the terminal performs the uplink sending operation, hoping to prevent the network side from entering the network energy saving mode.

Optionally, during the running of the periodic timer, the terminal does not perform the uplink sending operation. However, for the RRC connection establishment process or RRC connection recovery process (such as uplink data arrival, TAU update, RNAU update, RA update, and downlink paging message received) triggered by the existing procedures of the terminal, even if the periodic timer is still In operation, the UE may also initiate the RRC connection establishment procedure or the RRC connection recovery procedure.

Optionally, the configuration information includes the periodic timer, and the method further includes at least one of the following: a) when the terminal performs the uplink sending operation, starting or restarting the periodic timer b) when the terminal performs cell reselection, stop the periodic timer. Optionally, the relevant configuration of the periodic timer may be released; c) if the terminal receives the release instruction of the periodic timer, stop the periodic timer.

4) The terminal receives a paging message.

In this embodiment, the purpose of sending the paging message by the network side device is to determine the terminal in the unconnected state, that is, to trigger the terminal in the unconnected state to send an uplink signal to the network. In this way, after determining the resident status of the terminal in the non-connected state, the network side can take reasonable energy-saving measures, for example, decide not to enter the network energy-saving mode; another example, select a more suitable network energy-saving mode; Before the energy-saving mode, try to migrate the terminal in the non-connected state to another normal cell for camping, so as to avoid affecting the normal camping of the terminal in the non-connected state. In this embodiment, the paging message received by the terminal is not the paging triggered by the terminal's own downlink data or downlink signaling, but the paging triggered by the requirement of the network side (such as energy saving requirement). Therefore, the paging message here can be understood as being related to the energy saving function of the network side. Optionally, if the paging message carries a paging cause value, the paging cause value may also be set to a value related to the energy saving function of the network side.

Optionally, the uplink sending operation includes at least one of the following:

8) Send an RRC system message request message.

9) Sending a first uplink signal, where the first uplink signal is used to indicate the camping situation of the terminal in the cell. The first uplink signal may be a newly introduced uplink RRC message, such as an uplink wake-up signal.

10) Initiate a tracking area update (Tracking Area Update, TAU) process.

11) Initiate the registration area update process.

12) Initiate a radio access network notification area update (RAN-based Notification Area Update, RNAU) process.

13) Initiate a cell location update process.

In this embodiment, the purpose of the terminal performing the uplink transmission operation may be to cooperate with the network side equipment to determine the residence status of the terminal in the non-connected state (or to cooperate with the network side device to test the load of the cell), so as to determine the terminal in the non-connected state After the residency status of the network, the network side can take reasonable energy-saving measures, for example, decide not to enter the network energy-saving mode; another example, choose a more appropriate network energy-saving mode; another example, try to switch the non-connected terminal Migrate to other normal cells for camping, so as to avoid affecting the normal camping of the terminal in the unconnected state.

Taking 1) and 2) as examples, this embodiment is described. The terminal can initiate random access when the conditions are met, that is, 1). However, random access includes 2-step RACH and 4-step RACH, both of which involve receiving downlink signals of terminals. In order to assist the network side to save energy on the network, the terminal may not receive downlink signals, so the terminal may only be required to perform step 1, that is, step 2) of random access.

In the method for determining a terminal in a non-connected state provided in an embodiment of the present application, a terminal in a non-connected state performs an uplink transmission operation if a condition is met, and the condition is related to the energy-saving function of the network side. In this way, the network-side device can be based on the terminal The uplink sending operation detects the existence of a non-connected terminal, and then can take reasonable energy-saving measures to avoid affecting terminal performance and improve user experience.

Specifically, if the network side device detects the existence of a non-connected terminal, it can take reasonable energy-saving measures, for example, decide not to enter the network energy-saving mode; another example, select a more appropriate network energy-saving mode; another example, when entering the network Before the energy-saving mode, try to migrate the terminal in the non-connected state to another normal cell for camping, so as to avoid affecting the normal camping of the terminal in the non-connected state.

1) The first uplink resource used by the uplink sending operation is a predefined uplink resource. The predefined uplink resource may be used by the terminal to perform the uplink sending operation.

The first uplink resource may include: a random access resource; and a sending opportunity or window of the uplink sending operation.

The first uplink resource may be at least one of frequency domain resources, time domain resources, and air domain resources.

The first uplink resource may be periodic or aperiodic; it may be configured by the network side or stipulated in an agreement; or it may be mapped according to other uplink or downlink resources; it may be dedicated or non-dedicated.

2) When the satisfying condition includes receiving the first downlink indication information, the second uplink resource used by the uplink sending operation is determined according to the downlink signal carrying the first downlink indication information.

Optionally, the second uplink resource is associated with the downlink SSB corresponding to the first downlink indication information, and/or, the second uplink resource is associated with the downlink time domain and the time domain carrying the first downlink indication information /or frequency domain resource association.

For example, the terminal determines which preamble is used for uplink transmission according to the SSB index corresponding to the first downlink indication information.

Optionally, on the basis of embodiment 200, the terminal does not listen to the response of the network side to the uplink sending operation after performing the uplink sending operation; and/or, the terminal performs the uplink sending operation During the process, the response of the network side to the uplink sending operation is not monitored.

For example, in this embodiment, the uplink sending operation performed by the terminal includes sending a Preamble, and the terminal may not listen to the random access response message after sending the Preamble, which is beneficial to the terminal's energy saving; for the network side device, the network side device may not send the random access response message. Responding to the message is beneficial to the energy saving of the equipment on the network side.

Optionally, the method further includes: if the terminal enters a connected state after performing the uplink sending operation, the terminal requests the network side for RRC connection release.

On the basis of the foregoing embodiments, the uplink sending operation includes indication information, the indication information is used to indicate the reason for the uplink sending operation, and the reason for the uplink sending operation includes at least one of the following:

1) Instructing the network side that the terminal camps in the cell.

2) Auxiliary network side energy saving function.

Optionally, the reason for the uplink sending operation is indicated by at least one of the following: the uplink resource used by the uplink sending operation (for example, indicated by a dedicated CFRA resource); the first The cause value, for example, the recovery cause value carried in the RRC connection recovery request message, and the establishment cause value carried in the RRC connection establishment request message.

Optionally, embodiment 200 may further include the following steps: the terminal reports the first capability to the core network device, and the first capability is used to indicate whether the terminal supports the network-side energy-saving function. For the specific role of the first capability, please refer to The introduction of the following embodiments.

In order to describe the implementation ideas of the embodiments of the present application in detail, several specific situations will be described below.

It can be understood that as long as the terminal in the non-connected state residing in the cell sends an uplink signal to the network side, the network side will know that there is at least one terminal in the non-connected state in the cell. Currently, a terminal in the non-connected state only sends an uplink signal when it receives a downlink paging message, or when an uplink service occurs, or requests a system message, or executes TAU or RNAU. Specifically, when a downlink paging is received or an uplink service occurs, or a TAU or RNAU is performed, the terminal will initiate an RRC connection establishment procedure or an RRC connection recovery procedure. If requesting system information, the terminal will initiate an RRC system information request process. Therefore, it may be considered how to use the existing process or introduce a new process to trigger the non-connected terminal in the cell to actively send an uplink signal to the network side (that is, the uplink sending operation performed by the terminal).

Case 1

In this embodiment, when there is a demand for energy saving on the network side, the network side triggers the detection of a terminal in an unconnected state.

This embodiment can introduce new downlink indication information, referred to as the first downlink indication information, such as network load test indication (NW load estimation Indication) information, the terminal performs an uplink sending operation after receiving the first downlink indication information, and the uplink sending operation Can be one of the following:

1) Initiate random access (RACH).

2) Send a random access preamble (Preamble).

3) Sending a Radio Resource Control (Radio Resource Control, RRC) connection establishment request message.

4) Initiate the RRC connection establishment process.

5) Send an RRC connection recovery request message.

6) Initiate the RRC connection recovery process.

7) Initiate the RRC system message request process.

8) Send an RRC system message request message.

9) Sending a first uplink signal, where the first uplink signal is used to indicate the camping situation of the terminal in the cell. The first uplink signal may be a newly introduced uplink signal, such as an uplink wake-up signal (UL WUS) or a newly introduced RRC message.

10) Initiate a tracking area update (Tracking Area Update, TAU) process.

11) Initiate the registration area update process.

12) Initiate a radio access network notification area update (RAN-based Notification Area Update, RNAU) procedure.

13) Initiate a cell location update process.

In this embodiment, the first downlink indication information may be sent in the following ways 1) to 3):

1) Send via SIB (eg SIB1).

2) Send by short message.

3) Sending through a newly defined downlink message. Considering that there may be multiple non-connected terminals in a cell, and each terminal only listens to short messages at its own paging position, the network needs to repeatedly send the first indication information to multiple non-connected terminals at different times , there is a problem of low efficiency. Then, the first indication information may also be sent through a newly defined downlink message, and the terminal monitors the newly defined downlink message on a specific time-frequency resource, for example, a network energy saving message (NWPowerSaving message), so as to improve communication efficiency.

Optionally, the newly defined downlink message may be mapped with the SSB, for example, the newly defined downlink message is sent at a specific SSB, or sent in polling at each SSB.

In this embodiment, the terminal may perform an uplink sending operation immediately after receiving the first downlink indication information, for example, perform an uplink sending operation within a first time period after receiving the first downlink indication information.

It can be understood that the terminal in the non-connected state may not wish to enter the connected state, and it performs the uplink sending operation only to cooperate with the network to test the load condition of the cell. Therefore, after the terminal performs the uplink sending operation or during the process of the uplink sending operation, it does not need to monitor or receive the corresponding downlink signal or response, or the terminal can quickly leave the connected state after sending the uplink signal (if entering the connected state) .

However, from the perspective of the network side, the network side will also receive RRC connection establishment requests, RRC connection recovery requests, or system message requests normally initiated by other terminals, and the network side must meet the access requirements of these terminals. Therefore, it is necessary for the network side to be able to distinguish the uplink transmission operation initiated by the terminal due to normal services, or the uplink transmission for assisting the network side in detecting the camping condition of the cell. In order to solve this problem, the following methods can be considered:

1) If the uplink sending operation of the terminal is to send an uplink signal on the uplink resource specified by the network side, for example, send a specific preamble. In this way, the network can judge the motive of the UE's uplink transmission operation according to the preamble/uplink resource sent by the terminal (UE).

2) The UE sets a special establishment cause value or recovery cause value in the RRC connection establishment request message or RRC connection recovery request message initiated.

Optionally, the uplink resource used by the terminal to perform the uplink sending operation is related to the downlink SSB corresponding to the terminal receiving the first downlink indication information. For example, the terminal determines which preamble to use to send uplink according to the SSB index (index) corresponding to the first downlink indication information.

Subsequent embodiment 1, embodiment 2 and embodiment 3 are some examples of the above case 1.

In this embodiment, the network-side trigger condition for sending the first downlink indication information may be: 1) When the number of users in the connected state existing on the predefined network resources is less than or equal to the first threshold, the network side initiates the first downlink Indicates the sending of information. The first threshold may be 0. 2) The network side periodically sends the first downlink indication information.

Case 2

In this embodiment, some trigger conditions for uplink sending operations on the terminal side may be predefined, which may be triggered based on terminal mobility events, and may also be triggered periodically.

For the case of triggering based on terminal mobility events, considering the mobility of the terminal in the non-connected state, once the terminal in the non-connected state reselects to a cell that supports the network energy-saving function, the terminal can actively perform uplink transmission operations. The specific implementation method can be as follows:

1) The terminal reselects to the current cell. If the system message of the cell indicates that the cell is an energy-saving cell, the terminal performs an uplink transmission operation. For the description and method of the uplink transmission operation, refer to Case 1.

2) The network side can configure the energy-saving cell list for the terminal when releasing the terminal, for example, configure it in an RRC connection release message. When the target cell reselected by the terminal belongs to the list of energy-saving cells, the terminal immediately performs an uplink transmission operation, and the description and method of the uplink transmission operation can refer to case 1. Embodiment 4 is an example of the above method.

For the case of periodic triggering, the network side can configure the terminal to periodically send uplink information (that is, perform an uplink sending operation) when camping on the current cell through a system message.

Optionally, relevant network configuration information includes at least one of the following:

1) The pattern of the terminal's uplink transmission, that is, how long the terminal should trigger an uplink transmission operation; each uplink transmission operation can be sent in a predefined sending window, or according to configuration or predefined mapping The relationship determines the specific location of the upstream send operation.

2) A periodic timer for uplink transmission by the terminal; when the timer is not running or expires, the UE triggers an uplink transmission operation. During the period allowed by the timer, the terminal may not send uplink. Once the uplink is sent, the UE starts or restarts the timer. Once the cell is reselected, the terminal stops the timer. Optionally, delete the timer configuration.

3) Resource configuration for uplink transmission.

4) Energy-saving mode cycle at the network side. For example, the terminal may send an uplink signal to the network side before the network side enters the energy saving mode according to the period of the network energy saving mode.

Embodiment 6 is an example to the above-mentioned method.

Case 3

The case 3 mainly introduces a solution to an existing terminal (legacy UE).

For the network side, there may be terminals supporting this new function (referred to as new UE) and terminals not supporting this new function (referred to as legacy UE) residing in the cell. The network side can use the methods in the following embodiments 1 to 4 to trigger the new UE to actively perform the uplink transmission operation, but the legacy UE cannot transmit the uplink signal as expected because it cannot parse the newly introduced configurations.

Method 1: Considering that when a legacy UE receives a short message, if the short message carries a system information change indication (SI change indication), the UE will execute the system information (SI) acquisition process. If the network side sets multiple SIBs In a non-broadcasting manner, the terminal will request system information from the network side by acquiring system information on demand (ondemand SI) when receiving a system information change instruction.

Considering the method 1, because if the system message is not of interest to the terminal, the terminal may not initiate an ondemand SI request. Therefore, method 2 can be used.

Method 2: Consider that if the UE leaves the RA/TA/RNA area or receives a paging message, it will initiate an RRC connection establishment or RRC connection recovery procedure. The tracking area (Tracking Area, TA)/radio access network notification area (RANNotification Area, RNA) is configured by the network side when the terminal is connected, that is, it knows whether the terminal is a new UE or a legacy UE during configuration, and the base station It is possible to avoid configuring some energy-saving cells in the TA/RNA area for the legacy UE. When the legacy UE moves to the cell, it will initiate TAU/RNAU. This method is detailed in Example 5.

Optionally, for each embodiment of the present application, if the network side has entered the network energy-saving mode, the terminal may determine whether to trigger/execute the uplink sending operation according to the above rules according to the agreement or the instruction of the network side.

In order to describe in detail the method for determining a terminal in a non-connected state provided by the embodiment of the present application, the following will describe in conjunction with several specific embodiments.

Embodiment one

In this embodiment, the first downlink indication information is sent through a short message, and the UE sends a dedicated PRACH preamble after receiving it. This embodiment includes the following steps.

Step 1: The terminal in the RRC IDLE/INACTIVE state camps in cell 1.

Embodiment five

This embodiment mainly introduces a solution to the legacy UE, which triggers a mobility update process when the legacy UE enters an energy-saving cell (taking TAU as an example). This embodiment includes the following steps.

Step 1: The UE reports the first capability to the core network, and the first capability is used to indicate whether it supports the network energy-saving feature.

Step 2: The UE is configured with a TA list (list), which does not include the energy-saving cell 1, and this step can be realized by the network.

Step 3: The UE moves to the energy-saving cell 1, and initiates RRC connection establishment to execute the TAU procedure.

Step 4: The UE enters the connection state in the energy-saving cell 1, and is released back to the IDLE state by the network side. The TA list is updated by the network side, including the energy-saving cell 1. The serving base station can temporarily record the identification information of the terminal for local Cell paging terminal. The terminal identification information may be 5G-S-TMSI, where S-TMSI represents an MMEC Temporary Mobile Subscriber Identity (SAE-Temporary Mobile Subscriber Identity, S-TMSI). Step 5A: UE continues to camp on cell 1.

Step 6A: After receiving the paging message of cell 1 (the paging may be initiated by the base station of cell 1 or initiated by the base station requesting the core network), the UE initiates an RRC connection establishment request.

Step 7A: UE receives the RRC connection release message.

Step 5B: The UE reselects to another cell, and the network side may choose to remove the energy-saving cell 1 from the TA area when the terminal subsequently enters the connected state.

Summarizing the above steps, the core network supports at least one of the following operations:

1) When configuring TA/RA for a terminal, if the terminal does not support the network energy-saving feature, the core network does not configure the energy-saving cell into the TA/RA of the terminal. If it is already there, remove the energy-saving cell from TA/RA. Optionally, the base station that supports or intends to enter the energy saving mode requests the core network to perform the operation.

2) When the terminal initiates the TAU/RA update process, and the terminal initiates the TAU/RA update process in a cell supporting energy saving, the core network configures the energy-saving cell into the TAU/RA of the terminal.

Inspired by the above steps, the access network supports at least one of the following operations:

1) When configuring the RNA for the terminal, if the terminal does not support the network energy-saving feature, then the anchor base station does not configure the energy-saving cell into the RNA of the terminal. If it is already there, remove the energy-saving cell from the RNA. Optionally, the base station supporting or intending to enter the energy-saving mode requests the anchor base station to perform the operation.

2) When the terminal initiates the RNA update process, and the terminal initiates the RNA update process in a cell that supports energy saving, the anchor base station configures the energy-saving cell into the RNA of the terminal.

Considering that in actual deployment, a large number of energy-saving cells may not appear in one area, this method will not cause the UE to frequently initiate TAU/RNAU due to IDLE/INACTIVE mobility.
