The method for determining the non-connection state terminal provided by the embodiment of the application is described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 2, an embodiment of the present application provides a method 200 for determining a non-connection state terminal, which may be performed by the terminal, in other words, by software or hardware installed in the terminal, the method including the following steps.

S202: executing uplink sending operation under the condition that the terminal in the non-connection state meets the condition; wherein the condition relates to a network side energy saving function.

The network side energy saving function mentioned in the present application may be to close a base station, close a carrier, close a cell, close a channel, close a frequency point, close a frequency band combination, close a downlink, close an uplink, close a characteristic, close an SSB/beam, close an antenna, close a panel, etc. In addition to shutting down the corresponding network resources, it may also be selected to appropriately reduce or decrease the corresponding network side resources, e.g., reduce transmission power, reduce transmission bandwidth, shorten transmission time, etc. One or more of them can be executed by the network side to achieve energy saving effects of different degrees.

The non-connected state referred to in various embodiments of the present application may include an IDLE state (IDLE) or a non-active state (inactive), etc.

Optionally, the first uplink resource used by the uplink transmission operation is a predefined uplink resource. The predefined uplink resource may be used for the terminal to perform the uplink transmission operation.

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

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

The first uplink resource may be periodic or aperiodic; may be configured at the network side or agreed upon by a protocol; or according to other uplink or downlink resource mapping; may be dedicated or non-dedicated.

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

1) And the terminal receives the first downlink indication information.

The first downlink indication information relates to a network side energy saving function, and optionally, the first downlink indication information may be used to indicate at least one of the following: indicating that the network side equipment expects to enter a power saving mode; instructing the terminal to execute uplink transmission operation; indicating that the network side device desires to know the residence condition of the terminal in the cell, etc.

Optionally, the meeting the condition includes that the terminal receives the first downlink indication information, where the first downlink indication information may be received through at least one of the following: a) System information blocks (System Information Blocks, SIB); b) A short message; c) A predefined downstream message, said predefined downstream message being related to a network side power saving function.

Optionally, the predefined downlink message is mapped with a dedicated downlink resource, which may be used for the terminal to determine the content/action of the first downlink indication information. Optionally, the dedicated downlink resource includes at least one of: downlink time domain location; a downlink frequency domain location; synchronization signal/physical broadcast channel signal block/synchronization signal block (Synchronization Signal and PBCH block, SSB).

2) The terminal selects or reselects to a first cell, and the first cell supports or enables a network side energy saving function.

In this embodiment, the method may further comprise at least one of: a) The terminal receives a system message in the first cell, wherein 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 by a network side, wherein the energy-saving cell list information comprises information of cells supporting the energy-saving function of the network side; and the terminal determines that the first cell supports the energy-saving function of the network side according to the energy-saving cell list information.

Alternatively, the terminal may configure the energy saving cell list information through a broadcast message or a dedicated signaling (e.g., an RRC connection release message).

3) And the uplink sending operation reaches the triggering time, and the uplink sending operation is triggered periodically.

In this embodiment, the method further comprises: the terminal acquires configuration information, wherein the configuration information comprises at least one of the following components: a) Triggering time and repetition period of the uplink transmission operation; b) And configuring a periodic timer, wherein the terminal executes the uplink sending operation under the condition that the periodic timer is not operated or overtime.

In an embodiment, the network side may indicate to the terminal an energy-saving pattern (time or duration, period, etc.) of the network side, and the non-connected terminal residing in the present network may perform, based on the energy-saving pattern, the uplink transmission operation by the terminal before the time when the network side enters the energy-saving mode, so as to wish 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 transmission operation. However, for the RRC connection setup procedure or RRC connection recovery procedure triggered by the existing procedure of the terminal (e.g., uplink data arrives, TAU update, RNAU update, RA update, reception of downlink paging message), the UE may initiate the RRC connection setup procedure or RRC connection recovery procedure even if the periodic timer is still running.

Optionally, the configuration information includes the periodic timer, and the method further includes at least one of: a) The terminal starts or restarts the periodic timer under the condition of executing the uplink transmission operation; b) The terminal stops the periodic timer in case of performing a cell reselection. Optionally, the relevant configuration of the periodic timer may be released; c) And if the terminal receives the release instruction of the periodic timer, stopping the periodic timer.

4) The terminal receives the paging message.

In this embodiment, the function of the network side device to send the paging message is to determine the terminal in the non-connected state, that is, to trigger the terminal in the non-connected state to send an uplink signal to the network. In this way, after determining the residence condition of the terminal in the non-connection state, the network side can take reasonable energy-saving measures, for example, decide not to enter the network energy-saving mode; for another example, a more appropriate network power saving mode is selected; for another example, before entering the network energy-saving mode, the terminal in the non-connection state is tried to migrate to other normal cells for residence, so that the normal residence of the terminal in the non-connection state is prevented from being influenced. In this embodiment, the paging message received by the terminal is not a paging triggered by the terminal's own downlink data or downlink signaling, but a paging triggered by a network side demand (such as a power saving demand). Thus, the paging message herein may be understood as being related to a network side power saving function. Optionally, if the paging message carries a paging cause value, the paging cause value may also be set to a value related to the network side energy saving function.

Optionally, the uplink transmission operation includes at least one of:

1) Random Access (RACH) is initiated.

2) A random access Preamble (Preamble) is transmitted.

3) A radio resource control (Radio Resource Control, RRC) connection establishment request message is sent.

4) And initiating an RRC connection setup procedure.

5) And sending an RRC connection recovery request message.

6) An RRC connection recovery procedure is initiated.

7) Initiate RRC system message request flow.

8) And sending an RRC system message request message.

9) And sending a first uplink signal, wherein the first uplink signal is used for indicating the residence condition of the terminal in a cell. The first uplink signal may be a newly introduced uplink RRC message, for example, an uplink wake-up signal.

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

11 Initiating a registration area update procedure.

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

13 A cell location update procedure is initiated.

In this embodiment, the purpose of the terminal to perform the uplink sending operation may be to determine the residence condition of the non-connected terminal (or to test the cell load condition in cooperation with the network side device) in cooperation with the network side device, so that after determining the residence condition of the non-connected terminal, the network side may take reasonable energy-saving measures, for example, decide not to enter the network energy-saving mode; for another example, a more appropriate network power saving mode is selected; for another example, before entering the network energy-saving mode, the terminal in the non-connection state is tried to migrate to other normal cells for residence, so that the normal residence of the terminal in the non-connection state is prevented from being influenced.

Taking 1) and 2) as examples, the present embodiment will be described. The terminal may initiate random access, i.e. 1), if the condition is met. The random access includes a 2-step RACH and a 4-step RACH, both of which involve reception of a downlink signal of the terminal. In order to assist the network side in performing network energy saving, the terminal may not receive the downlink signal, so that the terminal may only be required to perform the step 1, i.e. 2) of random access.

According to the method for determining the non-connection state terminal, the terminal in the non-connection state executes the uplink transmission operation under the condition that the condition is met, and the condition is related to the energy-saving function of the network side, so that the network side equipment can detect the existence of the non-connection state terminal based on the uplink transmission operation of the terminal, reasonable energy-saving measures can be taken, the performance of the terminal is prevented from being influenced, and the user experience is improved.

Specifically, if the network side device detects the existence of the non-connection terminal, reasonable energy-saving measures can be taken, for example, the network energy-saving mode is not entered; for another example, a more appropriate network power saving mode is selected; for another example, before entering the network energy-saving mode, the terminal in the non-connection state is tried to migrate to other normal cells for residence, so that the normal residence of the terminal in the non-connection state is prevented from being influenced.

Optionally, on the basis of embodiment 200, the uplink transmission operation satisfies at least one of:

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

2) And when the meeting condition comprises that the first downlink indication information is received, determining a second uplink resource used by the uplink transmission operation according to a downlink signal carrying the first downlink indication information.

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

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 monitor a response of the network side to the uplink transmission operation after executing the uplink transmission operation; and/or the terminal does not monitor the response of the network side to the uplink sending operation in the process of executing the uplink sending operation.

In this embodiment, for example, the uplink sending operation performed by the terminal includes sending a Preamble, and the terminal may not monitor the random access response message after sending the Preamble, which is beneficial to saving energy of the terminal; for the network side equipment, the network side equipment does not need to send the random access response message, which is beneficial to the energy saving of the network side equipment.

Optionally, the method further comprises: and if the terminal enters a connection state after the uplink sending operation is executed, the terminal requests the RRC connection release to the network side.

On the basis of the foregoing embodiments, the uplink transmission operation includes indication information, where the indication information is used to indicate a cause of the uplink transmission operation, and the cause of the uplink transmission operation includes at least one of the following:

1) And indicating the terminal to reside in the cell to a network side.

2) Auxiliary network side energy saving function.

3) Responding to the first downlink indication information.

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

Optionally, embodiment 200 may further include the steps of: the terminal reports the first capability to the core network device, where the first capability is used to indicate whether the terminal supports the network side energy saving function, and for a specific function of the first capability, reference may be made to the description of the following embodiments.

In order to describe the implementation concept of the embodiments of the present application in detail, the following description will be made with reference to several specific cases.

It can be understood that, as long as the non-connected state terminal residing in the cell sends the uplink signal to the network side, the network side knows that at least one non-connected state terminal exists in the cell. Currently, a non-connected terminal will send an uplink signal only when it receives a downlink paging message, or an uplink service occurs, or a system message is requested, or TAU or RNAU is to be performed. Specifically, when downlink paging is received, uplink traffic occurs, or TAU or RNAU is performed, the terminal initiates an RRC connection establishment procedure or an RRC connection recovery procedure. If the system message is requested, the terminal initiates an RRC system message request flow. Therefore, it can be considered how to trigger the non-connected state terminal under the cell to actively transmit the uplink signal (i.e., the uplink transmission operation performed by the terminal) to the network side by using the existing procedure or introducing a new procedure.

Case 1

In this embodiment, when the network side has an energy saving requirement, the network side triggers the terminal detecting the unconnected state.

In this embodiment, new downlink indication information may be introduced, abbreviated as first downlink indication information, for example, network load test indication (NW load estimation Indication) information, and after receiving the first downlink indication information, the terminal performs an uplink transmission operation, where the uplink transmission operation may be one of the following:

1) Random Access (RACH) is initiated.

2) A random access Preamble (Preamble) is transmitted.

4) And initiating an RRC connection setup procedure.

5) And sending an RRC connection recovery request message.

6) An RRC connection recovery procedure is initiated.

7) Initiate RRC system message request flow.

8) And sending an RRC system message request message.

9) And sending a first uplink signal, wherein the first uplink signal is used for indicating the residence condition of the terminal in a 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 tracking area update (Tracking Area Update, TAU) procedures.

11 Initiating a registration area update procedure.

13 A cell location update procedure is initiated.

In this embodiment, the first downlink indication information may be transmitted by the following 1) to 3):

1) Transmitted through SIB (e.g., SIB 1).

2) And sending through short messages.

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

Alternatively, the newly defined downstream message may be mapped with the SSB, e.g., the newly defined downstream message is sent at a particular SSB or polled at each SSB.

In this embodiment, the terminal may perform the uplink transmission operation immediately after receiving the first downlink indication information, for example, during a first period of time after receiving the first downlink indication information.

It will be appreciated that a terminal in a non-connected state may not be expected to enter a connected state, and that it performs uplink transmission operations only to match the network test cell load situation. Therefore, after the terminal performs the uplink transmission operation or during the uplink transmission operation, the terminal does not need to monitor or receive the corresponding downlink signal or response, or the terminal can quickly leave the connection state after the terminal has transmitted the uplink signal (if entering the connection state).

However, from the perspective of the network side, the network side may also receive RRC connection establishment requests, RRC connection recovery requests, or system message requests normally initiated by other terminals, and the network side needs to meet the access requirements of these terminals. Therefore, it is necessary for the network side to be able to distinguish whether the terminal initiates an uplink transmission operation due to normal service or assists the network side in detecting the uplink transmission of the cell residence. To solve this problem, the following manner can be considered:

1) If the uplink transmission operation of the terminal is to transmit an uplink signal on an uplink resource designated by the network side, for example, a specific preamble is transmitted. In this way, the network can determine the motivation for uplink transmission operation of the terminal (UE) based on the preamble/uplink resources transmitted by the UE.

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

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

The following embodiment one, embodiment two and embodiment three are some examples of the above case 1.

In this embodiment, the triggering condition of the network side for sending the first downlink indication information may be: 1) And when the number of the connected state users existing on the predefined network resources is smaller than or equal to a first threshold value, the network side initiates the transmission of the first downlink indication information. The first threshold may be 0. 2) The network side periodically transmits first downlink indication information.

Case 2

The embodiment can predefine trigger conditions of some uplink sending operations at the terminal side, can be triggered based on a terminal mobility event, and can also be triggered periodically.

For the triggering situation based on the terminal mobility event, considering the mobility of the non-connected terminal, if the non-connected terminal reselects to a cell supporting the network energy-saving function once, the terminal can actively execute the uplink sending operation, and the specific implementation manner can be as follows:

1) The terminal reselects the current cell, if the system information of the cell indicates that the cell is an energy-saving cell, the terminal executes uplink sending operation, and the description and the method of the uplink sending operation can refer to the case 1.

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

For the case of periodic triggering, the network side may configure the terminal to periodically send uplink information (i.e. perform uplink sending operation) when the own cell resides through a system message.

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

1) The uplink sending mode (pattern) of the terminal, i.e. how long the terminal should trigger an uplink sending operation at intervals; each uplink transmission operation may be performed in a predefined transmission window, or a specific position of the uplink transmission operation may be determined according to a configuration or a predefined mapping relationship.

2) A periodic timer for uplink transmission of the terminal; and when the timer is not running or overtime, the UE triggers an uplink sending operation. The terminal may not transmit uplink during the timer grant. Once the uplink is sent, the UE starts or restarts the timer. Once the cell reselects, the terminal stops the timer. Optionally, the timer configuration is deleted.

3) And configuring uplink sent resources.

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

Embodiment six is an example of the above method.

Case 3

This case 3 mainly introduces a solution to the existing terminal (legacy UE).

For the network side, there may be a terminal (simply new UE) supporting the new function and a terminal (simply legacy UE) not supporting the new function that reside under the cell. The network side may employ the methods of the first to fourth embodiments 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.

Mode 1: considering that when the legacy UE receives the short message, if the short message carries a system information change instruction (SI change indication), the UE will execute a System Information (SI) acquisition procedure, and if the network side sets the SIBs to be in a non-broadcast mode, the terminal will request the network side for the system message by adopting a mode of acquiring system information (on demand SI) based on the requirement when receiving the system information change instruction.

Consider in mode 1 because if the system message is not of interest to the terminal, the terminal may not initiate an on demand SI request. Thus, mode 2 can be used.

Mode 2: consider that if the UE leaves the RA/TA/RNA area or receives a paging message, an RRC connection setup or RRC connection recovery procedure may be initiated. The Tracking Area (TA)/radio access network notification Area (RAN Notification Area, RNA) is configured by the network side when the terminal is connected, that is, the network side knows whether the terminal is new UE or legacy UE when the terminal is configured, the base station can avoid configuring some energy-saving cells into the TA/RNA Area for legacy UE, and when the legacy UE moves to the cells, TAU/RNAU is initiated. The method is described in embodiment five.

Optionally, for each embodiment of the present application, if the network side has entered the network energy saving mode, the terminal may determine, according to a protocol convention or an indication from the network side, whether the uplink transmission operation needs to be triggered/executed according to the above rule.

In order to describe the method for determining the non-connection state terminal according to the embodiment of the present application in detail, the following description will be made with reference to several specific embodiments.

Example 1

In this embodiment, the first downlink indication information is sent through a short message (short message), and the UE sends the dedicated PRACH preamble after receiving the first downlink indication information.

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

Step 2: the terminal receives the short message.

Step 3: if the short message carries the first downlink indication information, for example, NW load estimation Indication, the UE initiates random access.

Optionally, the UE sends a dedicated PRACH preamble to facilitate network side identification for terminal access purposes. The proprietary PRACH preamble related configuration may be obtained through a system message, or may be obtained according to a protocol agreed manner (for example, an association relationship defining some resources). Optionally, the UE only transmits the PRACH preamble, i.e. after the PRACH preamble is transmitted, the UE is not required to monitor the corresponding Random Access Response (RAR).

Example two

In this embodiment, the first downlink indication information is sent through a newly introduced downlink message, and the UE sends the dedicated PRACH preamble after receiving the first downlink indication information.

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

Step 2: the terminal listens for the newly defined downlink message (e.g., NW power saving message) at a predefined downlink time and/or frequency domain location.

Step 3: if NWPowerSaving message is received or the first indication information is carried in NWPowerSaving message received (NW load estimation Indication), the UE initiates random access.

Alternatively, the predefined downlink time domain and/or frequency domain location may be agreed by a protocol, or configured by the network side through a system message.

Other optional operations may be referred to in embodiment one.

Example III

In this embodiment, the first downlink indication information is sent through short message, and the UE initiates RRC connection establishment after receiving the first downlink indication information, which includes the following steps.

Step 1: the terminal in RRC IDLE state resides in cell 1.

Step 2: the terminal receives the short message.

Step 3: if the short message carries the first downlink indication information, the terminal sends an RRC connection establishment request message. Optionally, the connection establishment cause value carried by the UE in the RRC connection establishment request message is related to the first downlink indication information.

Step 4: after the UE sends the RRC connection establishment request message, the UE enters an RRC IDLE state after receiving the RRC connection release message of the network side, or the UE enters the RRC IDLE state by itself after sending the RRC connection establishment request.

Optionally, if the network side configures the dedicated PRACH Preamble dedicated for the uplink transmission, the UE may also directly send the dedicated PRACH Preamble, and if the network side does not configure the Preamble, the UE executes the steps 3-4.

Example IV

This embodiment mainly introduces a list of energy saving cells, which comprises the following steps.

Step 1: the terminal is in a connected state in cell 1 and receives the RRCRelease message.

Step 2: the RRC Release message carries the energy-saving cell list.

Step 3: the terminal is in the RRC IDLE/INACTIVE state and camps on cell 1.

Step 4: the terminal reselects to cell 2.

Step 5: if the terminal is configured with the energy-saving cell list and cell 2 belongs to a cell in the energy-saving cell list, the terminal initiates transmission of a first uplink message, which may be a newly introduced RRC message.

It will be appreciated that the use of the newly introduced RRC message helps the network side to identify the access purpose of the terminal and thus determine how to respond to the terminal.

Optionally, considering that the terminal may reside in the cell 2 for a long time, the network side may also configure an uplink transmission period when configuring the energy-saving cell list, so as to ensure that the UE may actively transmit an uplink signal at intervals.

Example five

This embodiment mainly describes a solution for Legacy UEs, and triggers a mobility update procedure (taking TAU as an example) when Legacy UEs enter into a power saving cell, and includes the following steps.

Step 1: the UE reports a first capability to the core network, where the first capability is used to indicate whether itself supports the network energy saving feature.

Step 2: the UE is configured with a TA list (list) that does not contain the energy saving cell 1, which may be implemented for the network.

Step 3: the UE moves to the energy saving cell 1, initiates RRC connection setup to perform the TAU procedure.

Step 4: the UE enters a connection state in the energy-saving cell 1, and then is released back to an IDLE state by the network side, and the TA list is updated by the network side, where the UE includes the energy-saving cell 1, and the serving base station may temporarily record the identification information of the terminal, so as to page the terminal in the cell. The terminal identification information may be a 5G-S-TMSI, wherein S-TMSI represents an MMEC temporary subscriber identity (SAE-Temporary Mobile Subscriber Identity, S-TMSI). Step 5A: the UE continues to camp on cell 1.

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

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

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

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

1) When configuring a TA/RA for a terminal, if the terminal is a terminal which does not support the energy-saving characteristic of the network, the core network does not configure an energy-saving cell into the TA/RA of the terminal. If so, the energy-saving cell is removed from the TA/RA. Optionally, the base station supporting or wanting to enter the power saving mode requests the core network to perform the operation.

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

Based on the elicitations of the above steps, the access network supports at least one of the following operations:

1) When configuring RNA for a terminal, if the terminal is a terminal which does not support the network energy-saving characteristic, the anchor base station does not configure an energy-saving cell into the RNA of the terminal. If present, the energy-saving cell is removed from the RNA. Optionally, the base station supporting or wanting to enter the power saving mode requests the anchor base station to perform the operation.

2) When a terminal initiates an RNA updating flow and the terminal initiates an RNA updating flow in a cell supporting energy saving, an 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 a slice area, this approach does not result in frequent TAU/RNAU initiation by the UE due to IDLE/INACTIVE mobility.

Example six

This embodiment mainly introduces Cell update (Cell update) at the Cell level, and includes the following steps.

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

Step 2: the terminal receives first configuration information from the system message, the first configuration information including a duration configuration of a cell update timer (cell update timer) and uplink transmission resources.

Step 3: upon receiving the first configuration information, the terminal transmits an uplink signal on a given uplink transmission resource and starts cell update timer.

Step 4A: (terminal continues to camp on cell 1 …) after cell update timer a timeout, the terminal transmits an uplink signal on the uplink transmission resource given again and starts cell update timer.

Step 4B: (terminal reselects to cell 2 …) the terminal stops cell update timer and deletes the first configuration information.

Alternatively, the value of cell update timer may be less than or equal to the location update timer registered by TAU, RNAU, 5G.
