Description

Information processing method, device and readable storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information processing method, an information processing device, and a readable storage medium.

Background

In order to reduce energy consumption and realize a green communication network, an energy-saving mechanism is introduced in a wireless communication system. One possible power saving scheme is for the power saving cell to minimize some common channels and signal transmissions. At this time, for UEs (User Equipment) in a non-connected state (rrc_idle state) and rrc_inactive state), the UEs cannot normally camp on the energy-saving cell or directly initiate access in the cell.

In general, when the energy-saving cell operates in the energy-saving mode, the network side also expects the UE not to access to the energy-saving cell as much as possible. However, in some cases, such as excessive non-connected UEs in the camping cell, the network side expects a small number of non-connected terminals to initiate access from the energy-saving cell, so as to reduce the load of the camping cell for receiving the access UE. For example, the energy-saving cell can provide higher-speed data service or support more functions, and the UE can obtain better service experience when being connected to the energy-saving cell. In this case, according to the existing procedure, the UE needs to undergo a certain conversion to operate in the energy-saving cell.

It can be seen that the prior art approach may cause unnecessary signaling overhead.

Detailed Description

In the embodiment of the application, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, a and/or B can be expressed as follows: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present application means two or more, and other adjectives are similar.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.

The embodiment of the application provides an information processing method and device, which are used for reducing signaling overhead.

The method and the device are conceived in accordance with the same application, and since the principles of solving the problems by the method and the device are similar, the implementation of the device and the method may be referred to each other, and the repetition is not repeated.

Referring to fig. 1, fig. 1 is a flowchart of an information processing method provided in an embodiment of the present application, as shown in fig. 1, including the following steps:

step 101, the terminal determines whether to initiate access at a second target;

Wherein the terminal is in an RRC non-connected state (e.g., rrc_idle state, rrc_inactive state, etc.) and the terminal resides on the first target.

In the embodiment of the present application, the target may include a cell, BWP, carrier wave, and the like. Of course, as technology expands, the content included in the object may also expand accordingly.

Specifically, the first target is a first cell, and the second target is a second cell; the second cells are one or more of candidate second cells, and the candidate second cells refer to cells for the terminal to initiate access, for example, cells for the terminal to select to initiate an RRC establishment procedure or an RRC recovery procedure. In the embodiment of the present application, the second cell may be an energy saving cell. The first cell and the second cell are different cells and the second cell cannot be the target cell (or may also be referred to as candidate cell) for cell selection and/or cell reselection by the terminal, i.e. the terminal cannot camp on the second cell. At this time, the initiating the access includes initiating an RRC setup procedure or an RRC recovery procedure.

Or the first target is a first carrier and the second target is a second carrier. The second carriers are one or more of candidate second carriers, and the candidate second carriers refer to carriers which can be selected by the terminal to initiate access. Optionally, the terminal initiates the access procedure by pre-configuring authorized resources.

Or the first target is a first BWP and the second target is a second BWP. The second BWP is one or more of candidate second BWP, which refers to BWP available for the terminal to select an access initiation. Optionally, the terminal initiates the access procedure by pre-configuring authorized resources.

Optionally, in the embodiment of the present application, the terminal may further acquire first information. For example, the terminal may acquire the first information from the first target, or the terminal may also acquire preconfigured first information.

Then, the terminal may determine whether to initiate access at the second target according to a preset policy and/or the first information. The preset strategy can be set by the terminal according to actual needs. For example, the preset policy may be a selection manner of selecting the second cell from the candidate second cells, for example, random selection, selection according to a priority order, selection according to a certain probability, or the like.

In a specific application, the terminal can combine the preset strategy and the first information to determine whether to initiate the access at the second target, or can determine whether to initiate the access at the second target according to the preset strategy or the first information alone.

Wherein the first information includes one or more of the following:

Service information of the terminal;

slice information of the terminal;

An Access category (Access category) of the terminal;

-an access identity (ACCESS IDENTITY) of the terminal;

a probability range or a weight range of the selected initiated access of the one or more candidate second targets;

a power saving mode of one or more candidate second targets;

the reason for initiating the access, such as the reason for initiating the RRC procedure;

the authorized resources are preconfigured.

If the first information includes a probability range or a weight range of the selected access of the one or more candidate second targets, the terminal selects whether to generate a random number alpha when the second target initiates the access, wherein alpha is more than or equal to 0 and less than or equal to 1. And if the random number alpha is positioned in the probability range or the weight range corresponding to the second target, the terminal determines whether to initiate access at the second target. Specifically, the terminal may determine that access is initiated at the second target only according to the determination result that the random number α is located in the probability range or the weight range corresponding to the second target. The judgment result can be combined with other information in the first information to be determined, and a final result is obtained.

In the embodiment of the present application, the calculation mode of the random number is not limited. Or the terminal may also match the calculated random number with the identifier of the target, and take a second target corresponding to the identifier (such as the cell number, the carrier number, the BWP identifier, etc.) of the target matched with the random number as the second target herein. Where the meaning of matching may include equality, meeting a certain mathematical relationship, such as proportionality, etc.

Taking the first target as a first cell and the second target as a second cell as an example, if the first information includes a probability range or a weight range of one or more candidate second cells selected to initiate an RRC procedure (including an RRC establishment procedure, an RRC recovery procedure, etc.), the terminal determines that when the second cell initiates the RRC establishment procedure or the RRC recovery procedure, a random number α is generated, where α is greater than or equal to 0 and less than or equal to 1.

For a plurality of cells (including the first cell and the candidate second cell, or may include only the candidate second cell), the cells are ordered in order of their index numbers from large to small. Meanwhile, as each cell has the probability of initiating the RRC process, the index number and the probability of initiating the RRC process have a corresponding relationship, and the probability of initiating the RRC process for each cell is also equivalent to that of sequencing the index number in the process of sequencing the index number.

And in the sorted index numbers, starting from the minimum index number, calculating the probability of initiating the RRC process corresponding to the index number to obtain intermediate probability. Specifically, for the first index number, the intermediate probability is equal to the probability of initiating the RRC procedure corresponding to the first index number. For each index number following the second index number, the intermediate probability is equal to the sum of the probabilities of initiating the RRC procedure corresponding to all index numbers preceding the index number. For example, for the third index, the intermediate probability is equal to the sum of the probability of initiating the RRC procedure corresponding to the first index, the probability of initiating the RRC procedure corresponding to the second index, and the probability of initiating the RRC procedure corresponding to the third index. Thus, different index numbers correspond to respective intermediate probabilities.

After calculating the intermediate probability, starting from the minimum index number, if the probability of initiating the RRC procedure of a certain cell is smaller than a certain intermediate probability and is closest to the intermediate probability, initiating the RRC procedure in the cell.

For example, the probability that the RRC procedure is initiated by the cell 1 broadcast cell 1 is 0.6, and the corresponding cell index number is 0 (or may be defaulted to 0); the probability that the cell 2 initiates the RRC process is 0.2, and the corresponding cell index number is 1 (the index number is 1 can be arranged according to the sequence in the cell list in the broadcast message); the probability of cell 3 initiating the RRC procedure is 0.2, the corresponding cell index number is 2 (the index number may be arranged to be 2 according to the order in the cell list in the broadcast message). The random number α is generated when the terminal performs a selection whether to initiate an RRC setup procedure or an RRC recovery procedure in the second cell. If α=0.5, which is smaller than the probability 0.6 corresponding to the RRC procedure initiated by cell 1, the terminal initiates an RRC establishment procedure or an RRC recovery procedure on cell 1; if α=0.7, which is smaller than (the probability that the cell 1 initiates the RRC procedure corresponds to 0.6+the probability that the cell 2 initiates the RRC procedure corresponds to 0.2) and closest to 0.8, the terminal initiates an RRC establishment procedure or an RRC recovery procedure on the cell 2; if α=0.85 is smaller than (the probability that the cell 1 initiates the RRC procedure corresponds to 0.6+the probability that the cell 2 initiates the RRC procedure corresponds to 0.2+the probability that the cell 3 initiates the RRC procedure corresponds to 0.2) and is closest to 1, the terminal initiates an RRC establishment procedure or an RRC recovery procedure on the cell 3; in this way, the second cell can be flexibly selected.

The reason for initiating the RRC procedure may be, for example, mo-signaling (mobile originated signaling, such as attach/location update/random access, etc.).

Wherein the energy saving mode includes one or more of:

A target operating mode;

A light sleep or light energy saving mode;

deep sleep or deep power saving mode;

And the DTX configuration information and/or the DRX configuration information of the candidate second cell.

In the above information, the target operation mode refers to a normal operation mode, that is, an operation mode different from the energy saving mode.

Wherein the pre-configured grant resources include one or more of:

Configuring an authorization configuration;

identification of candidate second targets corresponding to the resources;

Resource availability time information;

Judging configuration information of TA validity of the resource;

In the embodiment of the application, if the terminal is in the RRC non-connected state and the terminal resides in the first target, the terminal can determine whether to initiate access in the second target, thereby reducing signaling overhead.

Optionally, in an embodiment of the present application, if the first target is a first cell and the second target is a second cell, before or after step 101, the method may further include: the terminal performs a UAC procedure, wherein UAC parameters required for the UAC procedure are obtained from the first cell and/or the second cell. The UAC parameters may include UAC parameters corresponding to the first cell, UAC parameters of the second cell, and so on.

Specifically, if the UAC procedure is performed before step 101, the terminal may obtain UAC parameters from the first cell.

If a UAC procedure is performed after step 101, the terminal may obtain UAC parameters from the first cell and/or the second cell. In this case, the terminal performs the UAC procedure according to the UAC parameters of the second cell. If the result of the UAC process indicates that the access of the terminal is forbidden, the terminal terminates the RRC establishment process or the RRC recovery process initiated in the second cell, or the terminal takes the first cell as a target cell of the RRC establishment process or the RRC recovery process, and re-executes the UAC process; and if the result of the UAC procedure indicates that the terminal is allowed to access, the terminal executes an RRC establishment procedure or an RRC recovery procedure initiated in the second cell.

If the result of the re-executed UCA procedure indicates that the access of the terminal is forbidden, the terminal terminates the RRC establishment procedure or the RRC recovery procedure initiated in the first cell; and if the result of the re-executed UCA procedure indicates that the terminal is allowed to access, the terminal executes an RRC establishment procedure or an RRC recovery procedure initiated in the first cell.

In the above procedure, in case that the terminal determines to initiate the RRC procedure in the second cell, the terminal may acquire information required to initiate the RRC establishment procedure or the RRC recovery procedure in the second cell, and then perform the RRC establishment procedure or the RRC recovery procedure.

In the embodiment of the application, the terminal can obtain the information required for initiating the RRC establishment process or the RRC recovery process in the second cell in a plurality of modes.

Optionally, the terminal may acquire second information from the first cell, where the second information includes one or more of:

and the energy-saving mode of the candidate second cell.

Optionally, the terminal may acquire third information from the second cell, where the third information includes information required to initiate an RRC establishment procedure or an RRC recovery procedure in the second cell. In this case, the terminal may also transmit a first signal or a first message to the second cell, the first signal or the first message being used to acquire the third information. Then, the terminal receives, accordingly, third information transmitted by the second cell in response to the first signal or the first message. In the embodiment of the present application, the specific implementation form of the first signal or the first message is not limited, as long as the terminal and the second cell can process the first signal or the first message.

Wherein, the information required for initiating the RRC establishment procedure or the RRC recovery procedure includes one or more of the following information:

Of course, the information required for initiating the RRC setup procedure or the RRC recovery procedure is not limited to include the above information, and may be extended to a certain extent according to actual needs.

monitoring the access of the terminal;

Transmitting pilot signals according to a first preset rule;

And entering a target mode to work.

After the first signal or the first message is sent or the wake-up signal is sent, if the terminal does not receive the response message of the second cell within a predetermined time, the terminal performs the following operations:

Wherein the predetermined time may be set as desired.

and when the RRC establishment process or the RRC recovery process is completed, the second cell is the PCell.

Wherein the preconfigured grant resources are obtained from the first cell and/or the second cell. The pre-configured grant resources include content as previously described.

In the above embodiments, if the terminal initiates access after the second target, it may attempt to establish a connection or communication with the second target. For example, taking the second target as the second cell as an example, the terminal may take the second cell as the PCell when the RRC establishment procedure or the RRC recovery procedure is completed.

And entering a target mode to work.

Wherein, the explanation of the preset rules can refer to the description of the method embodiment.

One possible power saving scheme for the network in question is for the power saving cell to minimize the transmission of some common channels and signals. In this case, according to the prior art, the UE in the non-connected state (rrc_idle and rrc_inactive states) cannot normally camp on the energy-saving cell, and cannot directly initiate access in the cell. In general, when the energy-saving cell operates in the energy-saving mode, the network side also expects the UE not to access to the energy-saving cell as much as possible. However, in some cases, such as excessive non-connected UEs in the resident cell, the network side hopes that a small part of non-connected terminals can initiate access from the energy-saving cell, so that the load of the resident cell for receiving the access UEs is reduced; for example, the energy-saving cell can provide higher-speed data service or support more powerful functions, and the UE can obtain better service experience when being connected to the energy-saving cell. However, according to the existing procedure, the UE needs to initiate an RRC procedure from the camping cell and then switch to the energy-saving cell operation.

Therefore, the embodiment of the application provides an information processing method, when the non-connected state UE is resident in one cell, the RRC connection establishment or recovery process is initiated in the energy-saving cell, so that unnecessary signaling overhead and time delay are reduced.

In one embodiment of the application, the UE camps on a cell (first cell) from which information required to initiate the RRC procedure in the second cell (except for the preconfigured grant resources allocated to the UE by the second cell) may be obtained.

Assume that cell 2 and cell 3 are cells that provide hotspot coverage under cell 1 coverage. For some reason, for example, power saving or mobility management policies in rrc_idle and rrc_inactive states, cell 1 is a cell that can camp normally, and cells 2 and 3 cannot camp normally. The UE performing the cell selection and cell reselection procedures in the rrc_idle and rrc_inactive states cannot take cell 2 and cell 3 as target cells (which may also be referred to as candidate cells for the cell selection and cell reselection procedures), and cell 2 and cell 3 cannot camp as normal cells.

Cell 1 broadcasts some common configuration information of the own cell (corresponding to servingCellConfigCommon domain for use by the camping UE in listening to paging, receiving broadcast messages, and establishing or restoring RRC connection with the network side), UAC access parameters (or UAC parameters) in SIB1 (System Information Block, SIB, system information block).

Alternatively, cell 1 broadcasts that cell 2 and cell 3 (candidate second cells) can also be cells for RRC access when the UE camps on cell 1 (first cell). The cell selected to initiate the RRC procedure from among the candidate second cells is referred to as a second cell.

Optionally, cell 1 broadcasts configuration information related to cell 2 and cell 3 for rrc_idle and rrc_inactive state UEs to establish or resume RRC procedure usage with cell 2/cell 3.

The steps that may be involved in the UE initiating an RRC connection setup or recovery procedure at the second cell are described below.

In step 401, optionally, the UE (at this time, the UE may be in an RRC connected state or in an RRC inactive state) receives RRC RELEASE (RRC connection release) message, which carries a preconfigured grant resource, and is used to initiate or resume the connection with the second cell air interface after the UE enters the RRC non-connected state.

The pre-configured grant resources may include one or more of the following:

-Configured Grant configuration;

-the identity of the candidate second cell to which the resource belongs, i.e. the candidate second cell to which the resource corresponds;

-resource availability time: for determining when the configured resources are valid;

TA validity judgment configuration of resources: for determining whether the configured resources are still valid; if the TA change (e.g., via a path loss change) between the UE and the reference cell does not exceed a certain threshold, the configured resources are considered to be still valid, otherwise they may be considered to be invalid; the threshold value can be set according to the requirement, and the reference cell can be a first cell or a candidate second cell;

-RNTI of a resource;

-PUSCH configuration;

-PDCCH configuration;

-PDSCH configuration;

the UE stores the received pre-configured grant resources.

Step 402, the UE camps on cell 1. Here, the UE may be an rrc_idle state UE or an rrc_inactive state UE.

The UE may obtain a second cell list (i.e., candidate second cells including cell 2 and cell 3) initiating the RRC procedure from the broadcast information of cell 1, in addition to obtaining the information in SIB1 of the present cell.

Further, the UE may also obtain information required for initiating RRC procedures in cell 2 and cell 3 from the broadcast information of the first cell. For example, for each candidate second cell, one or more of parameters including frequency point information, BWP information, subcarrier spacing, CELL SPECIFIC PDCCH parameters, CELL SPECIFIC PDCSH parameters, CELL SPECIFIC PUSCH parameters, CELL SPECIFIC PUCCH parameters, SSB configuration parameters, DMRS symbol parameters, rate matching parameters, random access related parameters, UAC parameters, and the like are included.

Specifically, the information required for each of the cells 2 and 3 to initiate the RRC procedure in the NR (Radio) may be SIB1 of each cell or parameters included in IE (Information element ) ServingCellConfigCommon or ServingCellConfigCommonSIB.

Further, the UE may further obtain a candidate second cell energy saving mode from the broadcast information of the first cell. The power saving mode may include one of:

-a normal operating mode;

-either light sleep (LIGHT SLEEP) or light power saving mode;

-either deep sleep (DEEP SLEEP) or deep power saving mode;

Or the configuration of DTX on/off (active/inactive) and/or DRX on/off (active/inactive) of the candidate second cell (i.e. the configuration of discontinuous transmission of the candidate second cell) periodically (i.e. the configuration of discontinuous reception of the candidate second cell).

For example, cell 2 is currently in a light sleep mode; the current periodic DTX/DRX on/off configuration of the cell 3 starts with a certain T1 time, and the cell 3 performs normal reception/transmission in the first 80ms every 160ms, and enters the power saving mode in the last 80ms, and does not perform reception/transmission of data and/or signaling.

Optionally, the UE may further obtain factors involved in selecting the first cell or the candidate second cell as a target cell for the RRC procedure from the broadcast information of the first cell.

In step 403, when an AS (Access Stratum) layer of the UE needs to initiate an RRC connection procedure (if the UE is in an rrc_idle state) or an RRC recovery procedure (if the UE is in an rrc_inactive state), if the UE supports initiating the RRC procedure in a non-camping cell, the UE selects the first cell or the candidate second cell AS a target cell of the RRC procedure according to a certain rule. One or more of the following factors are considered in the rules:

-traffic information of the UE;

Slice information of UE;

-Access category (Access category);

-Access identity；

-a cause of initiating an RRC setup or recovery procedure;

-a probability range or a weight range of the selected initiating RRC procedure for the one or more candidate second cells;

-a power saving mode of one or more candidate second cells;

-pre-configuring authorized resources.

The above factors may be predefined by the protocol or configured by the network side (either by informing the UE via dedicated information, e.g. RRC RELEASE message, or by informing the UE via broadcast message, e.g. the broadcast message of cell 1 carries the above information.)

Specifically, the above factors may be arbitrarily combined.

For example, when the UE currently has an emergency service or a high priority service in progress, the UE selects cell 1 as a target cell for initiating the RRC procedure;

for example, when the UE currently selects a certain slice service, the UE selects cell 2 as a target cell for initiating the RRC procedure (e.g., only cell 2 can provide the slice service);

For example, when the UE measures that the signal strength of the cell 2 and the cell 3 is lower than a certain threshold, the UE selects the cell 1 as a target cell for initiating the RRC procedure;

for example, when the UE measures that the signal strength of the cell 1 is lower than a certain threshold 1 and the signal strength of the cell 2 is higher than a certain threshold 2, the UE selects the cell 2 as a target cell for initiating the RRC procedure;

For example, when the UE measures that the signal strength of the cell 1 is lower than a certain threshold 1 and the signal strength of the cell 2 is higher than a certain threshold 2, and the establishment is due to mo-signaling (mobile start signaling, such as attachment/location update/random access, etc.), the UE selects the cell 2 as a target cell for initiating the RRC procedure;

For example, when the UE measures that the signal strength of SSB index 1 of cell 1 is higher than a certain threshold 3,access identity by 0 (normal UE), and the UE generates a random number between 0 and 1, where the random number is in the range of the selected probability or the range of the weight of cell 2, the UE selects cell 2 as the target cell for initiating the RRC procedure;

For example, when the UE measures that the signal strength of the cell 3 is higher than a certain threshold 4, the access category of the procedure is MO data (mobile originated data), and the UE generates a random number between 0 and 1, where the random number is in the range of the selected probability or the range of the weight of the cell 3, the UE selects the cell 3 as the target cell for initiating the RRC procedure;

For example, when the UE measures that the signal strength of the cell 3 is higher than a certain threshold 4 and the cell 3 is currently in a normal working mode, the UE selects the cell 3 as a target cell for initiating the RRC procedure;

For example, when the UE measures that the signal strength of the cell 3 is higher than a certain threshold 4, and the cell 3 is currently in a light sleep mode, and the UE generates a random number between 0 and 1, where the random number is in a range of the probability or the weight of selecting the cell 3, the UE selects the cell 3 as a target cell for initiating the RRC procedure;

For example, when the UE determines that the cell 3 is currently in DTX on according to the DTX on/off configuration of the cell 3, the UE selects the cell 3 as a target cell for initiating the RRC procedure;

for example, when the UE measures that the signal strength of the cell 3 is higher than a certain threshold 4 and the UE has a valid preconfigured resource under the cell 3, the UE selects the cell 3 as a target cell for initiating the RRC procedure.

When no suitable candidate second cell satisfies the conditions required for the target cell initiating the RRC procedure, the UE defaults to using the first cell as the target cell initiating the RRC procedure.

Optionally, before the UE selects the first cell or the second cell as the target cell for initiating the RRC procedure, the UE performs the UAC procedure according to the UAC parameters broadcasted in cell 1 (the UAC parameters used are the same whether the RRC procedure is initiated in the first cell or in the second cell). If the UAC result is allowable, executing the subsequent process; if the UAC result is that access is forbidden, the current RRC process is terminated; this step is an optional step.

Optionally, the UE may perform step 404, i.e. perform the UAC procedure after selecting the target cell that initiates the RRC procedure.

In step 404, optionally, the UE performs a UAC procedure after selecting a target cell that initiates the RRC procedure.

The UAC parameters of cell 1 may or may not be the same as those of cells 2 and/or 3. When not, the UE performs the UAC procedure according to the determined target cell of the RRC procedure. For example, when the UE selects the cell 2 as the target cell of the RRC procedure, the UE determines the access control parameter of the access class (access category) in the cell 2, and performs access control judgment. The UE executes the following processes according to the UAC result:

If the UAC result is that the access is forbidden, the UE terminates the current RRC process, or selects the cell 1 as a target cell of the RRC process, re-executes the UAC process, if the access is not forbidden yet, the UE terminates the current RRC process, if the access is allowed, the UE executes the subsequent RRC process, at this time, the cell 1 is the target cell of the RRC process, and the UE initiates the RRC connection establishment or recovery process in the cell 1;

If the UAC result is allowed, the UE executes a subsequent RRC procedure, and the cell 2 is a target cell of the RRC procedure, and the UE initiates an RRC connection establishment or recovery procedure in the cell 2.

Step 405, optionally, the UE sends a wake-up signal.

After the UE determines that the second cell (e.g. cell 2) initiates the RRC procedure (i.e. after step 403 or step 404), the UE optionally sends a wake-up signal, which may include one or more of the following:

-for waking up the second cell, listening for access by a subsequent UE;

for waking up the second cell, transmitting a normal pilot signal, e.g. after the second cell receives the wake-up signal, transmitting an SSB signal with a period of 20ms for UE synchronization, even after a certain time period;

-for waking up the second cell, transmitting normal common signals and/or common channels; for example, the second cell may send cell common PDCCH (cell common PDCCH) after receiving the wake-up signal.

-For waking up the second cell, starting normal reception and transmission; for example, after the second cell receives the wake-up signal, the receiver and the transmitter are normally turned on.

-For waking up the second cell, switching to normal mode operation; for example, after the second cell receives the wake-up signal, the second cell no longer operates in the power saving mode.

Optionally, after the UE sends the wake-up signal, it waits for the response of the second cell. If no response is received from the second cell (e.g., cell 2) within a specified time, then:

the UE terminates the current RRC procedure, optionally considers the current access not allowed, and starts an associated timer (e.g., an access-forbidden timer); or the current access is considered to be refused, and a timer related to RRC connection refusal is started; or alternatively

The UE selects the first cell (i.e., cell 1) as the target cell for the RRC procedure and continues with the subsequent procedure.

The transmission mode (e.g., time, frequency, code resource, etc.) of the wake-up signal may be predefined or configured at the network side.

Step 406, the UE initializes an RRC connection setup procedure (for rrc_idle state) or an RRC connection recovery procedure for rrc_inactive state. If the target cell initiating the RRC procedure is a second cell, applying information acquired from the first cell and required to initiate the RRC procedure in the second cell; for example, applying the parameters included in IE ServingCellConfigCommon or ServingCellConfigCommonSIB under the received cell to the corresponding physical layer protocol;

The UE populates the RRC connection setup request message or the RRC connection recovery request message, wherein for the RRC connection recovery request message, the target cell is the second cell when the key update and/or calculation resumeMAC-I was performed (e.g., when the target cell that initiated the RRC procedure was previously determined to be cell 2, the target cell involved in the key update and/or calculation resumeMAC-I was cell 2).

The UE transmits an RRC connection setup request or an RRC connection restoration request message to the selected target cell. Optionally, if the UE currently has valid pre-configured grant resources of the target cell, the UE sends the above RRC message through the pre-configured grant resources, for example, when the UE obtains the pre-configured grant resources on cell 2 in step 401, and the UE sends an RRC connection establishment request or an RRC connection restoration request message to cell 2, the pre-configured grant resources are still valid, and then the UE sends the above UL (uplink) message to cell 2 through the pre-configured grant resources. (optionally, if the pre-configured grant resources also include DL resource configuration, the subsequent UE uses the configured DL resources when listening to DL (downlink)).

In step 407, the UE receives the RRC setup message or the RRC restoration message sent by the network side after the specified time, and the UE sets the target cell from which the RRC procedure is initiated as the PCell (e.g., the UE initiates the RRC procedure to the second cell (cell 2), where the UE sets the cell 2 as the PCell).

And when the UE receives other responses or other abnormal conditions occur, the UE is processed according to the existing mode.

In one embodiment of the application, the UE camps on a first cell and obtains information needed for access from a second cell that initiates an RRC procedure.

Cell 2 and cell 3 are cells that provide hotspot coverage under cell 1 coverage. For some reason, for example, power saving or mobility management policies in rrc_idle and rrc_inactive states, cell 1 is a cell that can camp normally, and cells 2 and 3 cannot camp normally. Cell 1 broadcasts some common configuration information of the own cell (corresponding to servingCellConfigCommon domain, used when the camping UE listens to paging, receives broadcast messages and establishes or resumes RRC connection with the network side), UAC (unified access control, unified access control mechanism) access parameters in SIB 1. In addition, cell 1 broadcasts that cell 2 and cell 3 may also be candidate second cells for initiating RRC procedures when the UE camps on cell 1 (first cell). The cell selected to initiate the RRC procedure from among the candidate second cells is referred to as a second cell.

Optionally, cell 1 also broadcasts the current energy saving mode of the candidate second cell.

Step 501 is the same as the description of step 401. Optionally, the UE (at this time, the UE may be in an RRC connected state or in an RRC inactive state) receives RRC RELEASE a message, where the message carries a preconfigured grant resource, and is used to initiate or resume connection with the second cell air interface after the UE enters the RRC non-connected state.

Step 502, the UE camps on cell 1 (first cell). Here, the UE may be an rrc_idle state UE or an rrc_inactive state UE.

The UE knows from the broadcast information of cell 1 that cell 2 and cell 3 can also be second cells initiating the RRC procedure, i.e. candidate second cells, when camping on cell 1, in addition to obtaining the information in SIB1 of the own cell.

Further, the UE may further obtain the current energy saving mode of the candidate second cell from the broadcast information of the first cell. The definition of possible energy saving modes can be referred to the description of the previous embodiments.

In step 503, when the AS layer of the UE needs to initiate an RRC connection procedure (if the UE is in an rrc_idle state) or an RRC recovery procedure (if the UE is in an rrc_inactive state), if the UE supports initiating the RRC procedure in the candidate second cell, the UE selects the first cell or the candidate second cell AS a target cell of the RRC procedure according to a certain rule. One or more of the following factors are considered in the rules:

-traffic information of the UE;

Slice information of UE;

-Access category (Access category);

-Access identity；

-a cause of initiating an RRC setup or recovery procedure;

-a power saving mode of one or more candidate second cells;

-pre-configuring authorized resources.

The above factors may be predefined by the protocol or configured by the network side (may be specific information, e.g. RRC RELEASE messages, or may be broadcast messages, e.g. cell 1 broadcast messages carrying the above information.)

Specifically, the above factors may be arbitrarily combined.

For example, when the UE currently has an emergency service or a high priority service in progress, the UE selects cell 1 as a target cell for initiating an RRC procedure;

For example, when the current service of the UE is insensitive to time delay and has large data volume, the signal strength of the cell 2 in the three cells capable of directly initiating access is best and is higher than a certain threshold value, the UE selects the cell 2 as a target cell for initiating the RRC procedure;

For example, when the signal strength of the cell 2 is higher than a certain threshold, and the UE generates a random number between 0 and 1, where the random number is in a probability range or a weight range that the cell 2 is selected to initiate the RRC procedure, the UE selects the cell 2 as a target cell for initiating the RRC procedure; (if cell 3 also meets this condition at this time, the UE selects the cell with the best signal strength as the target cell for initiating the RRC procedure);

For example, the signal strength of the cell 2 is higher than a certain threshold, and the current energy-saving mode of the cell 2 is a normal working mode, and the UE selects the cell 2as a target cell for initiating the RRC procedure;

For example, the signal strength of the cell 2 is higher than a certain threshold, and the cell 2 is currently in DTX on, the UE generates a random number between 0 and 1, where the random number is in a probability range or a weight range that the cell 2 is selected to initiate the RRC procedure, and then the UE selects the cell 2 as a target cell for initiating the RRC procedure;

for example, if the UE currently has valid pre-configured resources of cell 2, then the UE selects cell 2 as the target cell for initiating the RRC procedure;

When no suitable candidate second cell satisfies the conditions required for the target cell initiating the RRC procedure, the UE defaults to using cell 1 as the target cell initiating the RRC procedure.

Optionally, before the UE selects the first cell or the second cell as the target cell for initiating the RRC procedure, the UE performs the UAC procedure according to the UAC parameters broadcasted in cell 1 (the UAC parameters used are the same whether the RRC procedure is initiated in the first cell or the second cell). If the UAC result is allowable, executing the subsequent process; if the UAC result is that access is forbidden, the current RRC process is terminated; this step is an optional step.

Optionally, the UE may perform step 504, after selecting the target cell that initiates the RRC procedure, performing the UAC procedure.

In step 504, optionally, the UE performs a UAC procedure after selecting a target cell that initiates the RRC procedure. The UAC parameters of cell 1 may or may not be the same as those of cells 2 and/or 3. When the target cell is different, the UE performs UAC process in combination with the selected target cell of the RRC process; the UE may obtain UAC parameters of the second cell from the camping cell, for example, when the UE selects cell 2 (second cell) as a target cell of the RRC procedure, the UE determines an access control parameter under cell 2 of this access class (access category) to perform access control judgment. The UE executes the following processes according to the UAC result:

Alternatively, the UE may obtain the UAC parameters of the second cell from the second cell, where the UAC execution process needs to wait until the execution of step 505 is completed, and then execute the process of step 504.

Step 505, the UE obtains information required for access from the second cell.

The UE determines that after the second cell initiates the RRC procedure, the UE sends a signal or message to the second cell.

After receiving the signal or message, the second cell sends "information required to initiate RRC procedure" to the UE. One or more of frequency point information, BWP information, subcarrier spacing, CELL SPECIFIC PDCCH parameters, CELL SPECIFIC PDCSH parameters, CELL SPECIFIC PUSCH parameters, CELL SPECIFIC PUCCH parameters, SSB configuration parameters, DMRS symbol parameters, rate matching parameters, random access correlation, UAC, and the like may be included. Specifically, the parameters included in SIB1, IE ServingCellConfigCommon or ServingCellConfigCommonSIB may be applied to NR.

Optionally, after the UE sends the signal or the message, it waits for the response of the second cell. If no response of the second cell is received within a prescribed time, then:

the UE terminates the current RRC procedure, optionally considering that the current access is not allowed, starting an associated timer, e.g. a timer for prohibiting access); or the current access is considered to be refused, and a timer related to RRC connection refusal is started; or alternatively

The signaling or messaging means (e.g., time, frequency, code resources, etc.) may be predefined or configured at the network side.

Step 506, the UE initializes an RRC connection setup procedure (for rrc_idle state) or an RRC connection recovery procedure for rrc_inactive state), and if the target cell initiating the RRC procedure is the second cell, applies information obtained from the first cell and required to initiate the RRC procedure in the second cell; for example, applying the parameters included in IE ServingCellConfigCommon or ServingCellConfigCommonSIB under the received cell to the corresponding physical layer protocol;

The UE transmits an RRC connection setup request or an RRC connection restoration request message to the selected target cell. Optionally, if the UE currently has valid pre-configured grant resources of the target cell, the UE sends the above RRC message through the pre-configured grant resources, for example, when the UE obtains the pre-configured grant resources on cell2 in step 501, and the UE sends an RRC connection establishment request or an RRC connection restoration request message to cell2, the pre-configured grant resources are still valid, and then the UE sends the above UL message to cell2 through the pre-configured grant resources. (optionally, if the pre-configured grant resources also include DL resource configuration, the subsequent UE uses the configured DL resources while listening to DL).

In step 507, the UE receives an RRC setup message or an RRC restoration message sent by the network side after a specified time, where the UE sets a target cell for initiating an RRC procedure as a PCell (e.g., the UE initiates an RRC procedure to a second cell (cell 2), and at this time, the UE sets cell 2 as the PCell).

And when the UE receives other responses or other abnormal conditions occur, the UE can be in the existing mode.

In one embodiment of the application, it is assumed that the UE camps on a first carrier and initiates access on a second carrier.

A plurality of carriers (such as carrier 1, carrier 2, carrier 3 and the like) are arranged under the cell 1, wherein when the RRC idle/inactive UE resides in the cell 1, a system message is monitored on the carrier 1; other carriers (carrier 2, carrier 3, etc.) do not broadcast system messages; when the RRC idle/active UE performs cell selection or cell reselection evaluation, the measurement result on the carrier 1 is used as the radio channel condition of the cell 1.

The procedure by which the UE initiates access on the second carrier (i.e., one of the other carriers than carrier 1 under cell 1) is described below.

In step 601, optionally, UE1 (at this time, UE1 may be in an RRC connected state or in an RRC inactive state) receives RRCRELEASE a message, where a preconfigured grant resource is carried in the message, and is used for UE1 to initiate a dedicated resource used when the second carrier initiates access.

The pre-configured grant resources include one or more of the following:

-Configured Grant configuration;

-a second carrier identity to which the resource belongs;

-a resource availability time; for determining when the configured resources are valid;

-TA validity judgment configuration for the resource; for determining whether the configured resources are still valid, and if a TA change (such as by a path loss change) between the UE and the reference carrier does not exceed a certain threshold value, considering the configured resources as still valid; the reference carrier may be a first carrier or a second carrier;

-a resource-corresponding RNTI;

-PUSCH configuration;

-PDCCH configuration;

-PDSCH configuration;

the UE stores the received pre-configured grant resources.

Step 602, the UE camps on cell 1. Here, the UE may be an rrc_idle state UE or an rrc_inactive state UE.

Optionally, the UE obtains the current energy saving mode of the second carrier from the broadcast information of carrier 1. Possible energy saving mode definitions may include one of the following:

A normal operating mode;

Either light sleep (LIGHT SLEEP) or light power saving mode;

Either deep sleep (DEEP SLEEP) or deep power saving mode;

or a DTX/DRX on/off configuration of the second carrier (i.e., a configuration of the second carrier periodically performing discontinuous reception/transmission);

Optionally, the UE may further obtain factors involved in selecting the first carrier or the candidate second carrier as the access carrier from the broadcast information of carrier 1.

In step 603, when the AS layer of the UE needs to initiate an RRC connection procedure (if the UE is in an rrc_idle state) or an RRC recovery procedure (if the UE is in an rrc_inactive state), the UE selects the first carrier or the second carrier AS an access carrier according to a certain rule. One or more of the following factors are considered in the rules:

-traffic information of the UE;

Slice information of UE;

-Access category (Access category);

-Access identity；

-a cause of initiating an access;

-selected initiate access probability or weight;

-a power saving mode of the second carrier;

-preconfigured resources;

The above factors may be predefined by the protocol or configured by the network side (may be dedicated information, such as RRC RELEASE messages, or may be broadcast messages, such as those carried in cell 1).

For example, when the UE currently has an emergency service or a high priority service in progress, the UE selects the first carrier as an access carrier;

For example, when the current service of the UE is insensitive to time delay and has large data volume, the signal strength of the carrier 2 in the three carriers initiating access is the best and is higher than a certain threshold value, the UE selects the carrier 2 as the access carrier;

For example, when the current service of the UE corresponds to SDT (SMALL DATA transmission, small data) RB (radio bearer) and SDT resources are configured on carrier 2, the UE selects carrier 2 as an access carrier;

For example, if the current UE has a pre-configured resource that is valid on the carrier 2, and the data or signaling to be transmitted needs to use the pre-configured resource, the UE selects the carrier 2 as an access carrier;

when no suitable second carrier meets the conditions required to initiate access, the UE defaults to using the first carrier as an access carrier.

Step 604, the UE initiates access on the selected second carrier.

Optionally, if the UE currently has a pre-configured grant resource corresponding to the valid second carrier, the UE initiates an access procedure through the pre-configured grant resource.

In addition, in this embodiment, the carrier wave may be replaced with BWP. I.e. there are multiple BWP (e.g. BWP1, BWP2, BWP3, etc.) under cell 1, wherein the RRC idle/inactive UE listens for system messages on BWP1 while camping on cell 1; other BWP (e.g., BWP2, BWP 3) do not broadcast the system message; when the RRC idle/active UE performs cell selection or cell reselection evaluation, the measurement result on the BWP1 is used as the wireless channel condition of the cell 1. Other specific implementation processes are the same as the principle of the implementation process.
