Detailed ways

The technical solutions in the embodiments of the present disclosure will be clearly described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in this disclosure, all other implementations available to those of ordinary skill in the art Examples all fall within the scope of protection of this disclosure.

The terms "first", "second", etc. in the description and claims of the present disclosure are used to distinguish similar objects and are not used to describe a specific order or sequence. It is to be understood that the terms so used are interchangeable under appropriate circumstances so that embodiments of the present disclosure can be practiced in sequences other than those illustrated or described herein, and that "first" and "second" are distinguished objects It is usually one type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the related objects are in an "or" relationship.

In order to facilitate understanding of the technical solutions of the present disclosure, the following technical points are introduced below:

1. Introduction to the paging process:

The paging process allows the network to find UEs in the idle (IDLE) and inactive (INACTIVE) states through paging messages. The IDLE state UE monitors the paging channel used by the core network (Core Network, CN) to trigger paging. INACTIVE state UE monitors the paging channel used for CN-triggered paging and Radio Access Network (RAN)-triggered paging.

The paging process is shown in Figure 1. The UE does not need to monitor the paging channel all the time. By configuring paging Discontinuous Reception (DRX), the UE in the IDLE state and INACTIVE state only needs to monitor the paging opportunity (paging Occasion) in each DRX cycle. Call the channel.

For UEs in the IDLE state, when the UE releases the context, the base station (the next Generation Node B, gNB) may provide a list of recommended cells and gNBs to the Access and Mobility Management Function (AMF) for subsequent search. Call auxiliary information. The AMF may also include the paging attempt count, the expected number of pagings, and the next paging area range in the paging attempt information. If the above paging attempt information is included in the paging message, each paging node will The same information is received during the paging attempt.

For UEs in the INACTIVE state, during RAN paging, the serving gNB provides paging area information and may also provide RAN paging attempt information. In a paging attempt, all paged gNBs receive the same paging attempt information, including: paging attempt count, expected number of paging attempts, and next paging area range.

After receiving the paging message, the IDLE state UE sends the UE identity, access type and other information to the Non-Access-Stratum (NAS), and then the UE NAS layer initiates radio resource control (Radio Resource Control (RRC) connection establishment request. The RRC connection establishment process is shown in Figure 2. Once the UE in the INACTIVE state receives a paging triggered by the RAN, the UE triggers the RRC connection recovery process. The RRC connection recovery process is shown in Figure 3. If a paging triggered by the CN is received, the UE moves to the IDLE state and notifies the NAS.

3. About slice-based cell reselection

In related technologies, in order to support IDLE state and INACTIVE state UEs to camp in advance on the cell that supports the UE's most desired slice, a slice-based cell reselection function is introduced. A UE that supports slice-based cell reselection can obtain slice-specific cell reselection information from system messages and/or RRC Release messages. Slice-specific cell reselection information may include reselection priorities for each slice group on each frequency and corresponding cells that support or do not support NSAG (e.g., Network Slice AS Group (NSAG)) List information. The UE obtains the slice group and the priority corresponding to the slice group through the NAS. Based on the reselection priority in the system message or RRC Release message and the slice priority in the NAS message, the UE derives the slice-based cell reselection priority based on the following rules:

(1) Frequencies that support at least one priority NSAG received from the NAS have a higher reselection priority than frequencies that do not support priority NSAG;

(2) For frequencies that support at least one NSAG, sort according to the priority order of the highest priority NSAG for the frequency provided by the NAS;

(3) Among frequencies that support NSAGs with the same highest priority, sort in the order of their frequency priority specific to each NSAG;

(4) The frequency that supports the NSAG provided by the NAS and indicates nsag-CellReselectionPriority for the NSAG has a higher reselection priority than the frequency that supports the priority NSAG but does not indicate nsag-CellReselectionPriority for the NSAG.

(5) Frequencies that do not support any NSAG provided by NAS are arranged in the order of original non-slice-specific cell reselection priorities.

After the UE derives the slice-based cell reselection priority based on the above rules, it performs cell reselection from the highest priority frequency according to the frequency priority. If the best-ranked cell on that frequency supports the slice that the UE most wants, the UE is reselected to that cell. If the best-ranked cell on the frequency does not support the slice that the UE wants most, the UE considers that the frequency does not support the slice that the UE wants most, and determines the frequency according to the above Principle recalculates slice-based cell reselection priorities. The validity time of the recalculated cell reselection priority is up to 300s. The UE performs slice-based cell reselection according to the calculated slice-based cell reselection priority order until a cell is selected to camp on.

This embodiment describes the following scenario: when the UE is in the IDLE state or the INACTIVE state, the paging message received contains slice information of downlink data. The slice information may be a slice identifier or a slice group identifier (such as NSAG) information. The UE learns from the system message of the serving cell that receives the paging message that the cell does not support slices or slice groups (such as NSAG) for downlink data.

Embodiment 2: Based on the slice information of downlink data, the UE performs cell reselection on all frequencies before initiating random access.

This embodiment describes the following scenario: when the UE is in the IDLE state or the INACTIVE state, the paging message received contains slice information of downlink data. The slice information may be a slice identifier or a slice group identifier (NSAG) information. The UE learns from the system message of the serving cell that receives the paging message that the cell where it is located does not support slices or slice groups (such as NSAG) for downlink data. The UE performs switching based on downlink data on all frequencies in the system message according to the system information or RRCRelease message. Slice or slice group (NSAG) cell reselection. After the UE reselects a cell that supports the slice or NSAG, the UE initiates random access and receives downlink slice service data. A brief flow chart of this embodiment is shown in Figure 7.

The detailed steps are as follows:

(1) The UE in the IDLE state or the INACTIVE state receives the paging message. In the paging message, the UE learns the slice information of the downlink data. The slice information may include but is not limited to a slice identifier or a slice group identifier (NSAG);

(2) The UE knows from the system information of the serving cell that received the paging message that the current cell does not support slices or slice groups (such as NSAG) for downlink data;

(3) The UE is based on the slice information of the downlink data in the paging message, the priority of the slice or slice group (such as NSAG) provided by the UE NAS layer, and the slice-specific frequency priority in the system message or RRCRelease message, and in accordance with the following rules Derive the cell reselection priority based on downlink slice data:

-The slice or slice group (NSAG) of the downlink data in the paging message received by the UE has the highest priority;

- The frequency of a slice or slice group (NSAG) that supports at least one priority NSAG or downstream data received from the NAS has a higher reselection priority than the frequency of a slice or slice group (such as an NSAG) that does not support priority NSAG or downstream data. class;

-For frequencies that support slices or slice groups (such as NSAG) for downlink data in paging messages, they are ranked with the highest priority; for other frequencies that support at least one NSAG, the highest priority NSAG supported by the frequency provided by the UE NAS is Sort by priority;

- Among frequencies supporting NSAGs of the same highest priority or supporting downstream data slices, sorted in the order of their frequency priority specific to each NSAG or downstream data slice;

-Support the downlink data slice or slice group (NSAG) in the NSAG or paging message provided by the UE NAS layer and provide the frequency of reselection priority value than support the downlink data slice or slice group (such as NSAG) in the priority NSAG or paging message. Frequencies that do not provide a reselection priority value have a higher reselection priority;

- The frequency of downlink data slices or slice groups (such as NSAG) in any NSAG or paging message provided by NAS is not supported, and is arranged in the order of the original non-slice-specific cell reselection priority. List;

(4) The UE derives the reselection priority of the slice or slice group based on downlink data based on the above rules, and performs cell reselection based on the slice of downlink data. The UE performs measurement evaluation on these frequencies according to the priority order of the above frequencies until a cell is reselected.

(5) After receiving the paging message, the UE starts a timer (optional). If during the timer running period, the UE reselects a cell that supports a slice or slice group (such as NSAG) for downlink data, the UE will The identification, access type and reselection success are indicated to the UE NAS layer, and the UE NAS layer triggers the RRC connection establishment process or RRC connection recovery process. After the UE accesses the network, it receives downlink slice service data;

(6) If the UE reselects to a cell that does not support the slice or slice group of the downlink data during the timer operation, the UE continues to perform cell reselection or the UE indicates the UE identity, access type and reselection failure to the UE NAS layer, the UE NAS layer decides whether to initiate random access;

(7) If the timer expires and the UE still has not reselected to a cell that supports the slice or slice group (such as NSAG) of the downlink data in the paging message, the UE will indicate the UE identity, access type and reselection failure to the UE NAS layer , the UE NAS layer decides whether to initiate random access.

Embodiment 3: Based on the slice information of downlink data, the UE directly initiates random access in the serving cell, and then switches to a cell that supports the slice.

This embodiment describes the following scenario: when the UE is in the IDLE state or the INACTIVE state, the paging message received contains slice information of downlink data. The slice information may be a slice identifier or a slice group identifier (such as NSAG) information. The UE learns from the system message of the serving cell that receives the paging that the cell where it is located does not support slices or slice groups (such as NSAG) for downlink data. The UE directly initiates random access in the serving cell. After the base station establishes an RRC connection with the UE, based on the slice information of the downlink data and the measurement report of the cell that supports downlink data slices or slice groups (such as NSAG), when certain conditions are met, such as the quality of the cell reaches a certain threshold, the base station switches the UE In a cell that supports downlink data slicing or slicing group (NSAG), the UE receives downlink slicing data services. A brief flow chart of this embodiment is shown in Figure 8.

The detailed steps are as follows:

(1) A UE in the IDLE state or INACTIVE state receives a paging message. In the paging message, the UE learns the slice information of the downlink data sent to the UE. The slice information may include But not limited to slice identifiers or slice group identifiers (such as NSAG);

(2) According to the system information of the serving cell that received the paging message, the UE knows that when the current cell does not support slices or slice groups (such as NSAG) for downlink data, the UE will add the UE identity, access type and slice information of downlink data to At least one item is delivered to the UE NAS layer, and the slice information may be a slice identifier or a slice group identifier (such as NSAG);

(3) The UE NAS layer triggers the RRC connection establishment process or RRC connection recovery process, and carries the downlink data slice information (optional) in the RRC connection establishment request message or RRC connection recovery request message;

(4) After the base station establishes an RRC connection with the UE, based on the slice information of the downlink data and the measurement report of the cell that supports downlink data slices or slice groups (such as NSAG), when certain conditions are met, such as the quality of the cell reaches a certain threshold, the base station Switch the UE to a cell that supports downlink data slicing or slicing groups (such as NSAG);

(5) After the UE switches to a cell that supports the slice or slice group (such as NSAG) of the downlink data in the paging message, the UE receives the downlink data.

Embodiment 4: When the serving cell supports downlink data slicing information, random access is directly initiated in the serving cell.

This embodiment describes the following scenario: when the UE is in the IDLE state or the INACTIVE state, the paging message received contains slice information of downlink data. The slice information may be a slice identifier or a slice group identifier (such as NSAG) information. When the UE learns that its cell supports slices or slice groups (such as NSAG) for downlink data based on the system message of the serving cell that receives the paging, the UE directly initiates random access in the cell. Based on the measurement results of cells that support the slice or slice group of downlink data in the paging message, the base station switches the UE to a cell with higher quality when certain conditions are met, such as when the cell quality of the target cell is higher than the quality of the current cell by a certain threshold. In a good slice or slice group (such as NSAG) cell that supports paging messages, the UE continues to receive downlink slice service data. The brief process of this embodiment is shown in Figure 9:

The detailed steps are as follows:

(2) Based on the system information of the serving cell that received the paging message, the UE knows that when the current cell supports slices or slice groups (such as NSAG) for downlink data, the UE will add the UE identity, access type, and slice information of downlink data to At least one item is delivered to the UE NAS layer, and the slice information may be a slice identifier or a slice group identifier (such as NSAG);

(3) The NAS layer of the UE triggers the RRC connection establishment process or the RRC connection recovery process. After the RRC connection is established between the UE and the base station, the UE starts to receive downlink slice service data;

(4) After the base station establishes an RRC connection with the UE, based on the slice information of the downlink data and the measurement report of the cell that supports the downlink data slice or slice group (such as NSAG), when certain conditions are met, such as the cell quality of the target cell is better than that of the local cell. When the cell quality is higher than a certain threshold, the base station switches the UE to a cell with better cell quality and a slice or slice group (such as NSAG) that supports paging messages;

(5) After the UE switches to a cell that supports the slice or slice group (such as NSAG) of downlink data in the paging message, the UE continues to receive downlink data.
