Currently, the 5G NR system includes three connection states: an RRC idle state, an RRC connected state, and an RRC activated state.

For a terminal in an inactive state, there is currently no cell selection or reselection scheme for a terminal in an inactive state.

Although the terminal can switch between the above three states, the cell selection or reselection scheme of the terminal in the idle state cannot be applied to the terminal in the inactive state. First, since only a part of the Long Term Evolution (LTE) system cell (a cell that can connect to the 5G core network) and all 5G NR system cells support inactive state signaling configuration and related signaling, when the terminal selects or Reselecting a cell that does not support the inactive state (such as an LTE cell connected to the EPC) will not be able to support the inactive process in the inactive state, such as RRC connection recovery/suspension, small packet transmission, and the like. Secondly, the access stratum (AS) context of the inactive terminal has a certain intra-area activity, and the area can generally be regarded as an access network tracking area configured by the terminal in which the network device is inactive ( RNA Notification area, RNA), when the inactive terminal is reselected to an inter-RAT cell (for example, the cell is an LTE cell connected to the EPC), not in the RNA range, the AS context of the terminal will be unable to be in the network. The side is restored and released automatically.

For the above problem, an embodiment of the present invention provides a cell selection method, a terminal, and a network device. For a terminal in an inactive state, the network device sends a first indication information to the terminal, where the first indication information is used to indicate whether to allow or prohibit the non- The terminal in the active state selects the first cell, so that the terminal in the inactive state can determine the candidate cell of the inactive cell according to the indication of the first indication information when the cell is selected and reselected. The active terminal can select as many cells as possible that support the inactive state and/or the UE AS context.

It should be noted that the cell selection in the embodiment of the present invention includes: initial cell selection, and/or cell reselection, where "selection" only emphasizes the selected action, whether it is the initial cell selection or the cell weight.

FIG. 2 is a schematic flowchart diagram of a cell selection method according to an embodiment of the present invention. The method specifically includes:

S201. The network device sends the first indication information to the terminal.

Correspondingly, the opposite terminal receives the first indication information.

The network device in the embodiment of the present invention may be a network device in the communication system shown in FIG. 1, for example, a base station; the terminal in the embodiment of the present invention may be a terminal device in the communication system shown in FIG.

The first indication information is used to indicate that the terminal in the inactive state is allowed or disabled to select the first cell.

Exemplarily, the terminal in the embodiment of the present invention is a terminal in an inactive state.

In the embodiment of the present invention, the first indication information may be carried in a system message sent by the network device to the terminal. Exemplarily, the foregoing system message may be a Master Information Block (MIB), a System Information Block Type 1 (SIB1), and a Remaining Minimum System Information (RMSI).

S202. The terminal determines, according to the first indication information, a candidate cell of the terminal in an inactive state.

In the embodiment of the present invention, when the first indication information is used to indicate that the terminal that allows the inactive state selects the first cell, the terminal in the inactive state uses some or all of the first cells as the inactive terminal according to the first indication information. The candidate cell, that is, the candidate cell described above is part or all of the cells in the first cell.

In the embodiment of the present invention, when the first indication information is used to indicate that the terminal in the inactive state is selected to select the first cell, the terminal in the inactive state does not use the first cell as a candidate for the inactive terminal according to the first indication information. The cell, that is, the candidate cell described above does not include the first cell.

In the embodiment of the present invention, in the process of performing cell selection or reselection, the terminal in the inactive state performs different operations according to different roles of the first indication information.

In an example, when the first indication information is used to indicate that the terminal that prohibits the inactive state selects the first cell, the terminal in the inactive state may not consider the first cell as the candidate cell for a period of time. Alternatively, when the first indication information is used to indicate that the terminal in the inactive state is allowed to select the first cell, the terminal in the inactive state considers the first cell as a candidate cell.

Optionally, the first indication information sent by the network device to the terminal may be specifically in the following three forms. specific:

The first form:

The network device directly indicates the first indication information.

Exemplarily, the first indication information is information indicating that the terminal that allows the inactive state selects the first cell, or information that prohibits the terminal in the inactive state from selecting the first cell.

The second form:

Example 1: If the first indication information contains an RNA ID and corresponding bar information. Assuming that the RNA ID=1, the corresponding bar information includes but is not limited to the following two combinations: Example 1) RNA ID=1, prohibition; Example 2) RNA ID=1, not Barred.

Example 2: If the first indication information includes multiple RNA IDs and corresponding bar information. Taking two RNA IDs as an example, assuming that the two RNA IDs are 7 and 10, respectively, the corresponding bar information includes but is not limited to the following four combinations: Example 1) RNA ID=7, barred; RNA ID=10 , barred; Example 2) RNA ID=7, barred; RNA ID=10, not Barred; Example 3) RNA ID=7, not Barred; RNA ID=10, barred; Example 4) RNA ID=7, not Barred; RNA ID=10, not Barred.

In this form, in the process of performing cell selection or reselection by the corresponding inactive terminal, different operations are performed according to different roles of the first indication information. specific:

The terminal in the inactive state does not consider the cell belonging to the M RNA as a candidate cell for a period of time, or the terminal in the inactive state considers the cell belonging to the M RNA as a candidate cell.

The third form:

The network device sends a blacklist to the inactive terminal to assist the terminal in the inactive state to perform cell selection.

For example, the first indication information includes a blacklist, and the blacklist includes an identifier of the at least one first cell, where the first indication information is used to indicate that the terminal in the inactive state is prohibited from selecting the at least one first cell.

In one example, the blacklist described above may be carried in a system message or RRC dedicated signaling.

Exemplarily, when the blacklist is used to assist the terminal in the inactive state to perform initial cell selection, the foregoing system message may be: MIB, SIB1, RMSI, and the like. When the blacklist is used to assist the terminal in the inactive state to perform the cell selection, the foregoing system message may be: SIB3, SIB4, SIB5, SIBx newly introduced by the system message, and other system information (OSI).

Exemplarily, the foregoing RRC dedicated signaling may be: an RRC Connection Release message, an RRC Connection Resume message, an RRC Connection Suspend, and an RRC Connection Reconfiguration message. RRC Connection Reconfiguration).

The foregoing system message example and the RRC-specific signaling example are only a description, and the system message and the RRC-specific signaling are not limited. The embodiment of the present invention does not limit the system message and the RRC dedicated signaling.

In this form, in the process of performing cell selection or reselection by the corresponding, inactive terminal, the following operations are performed. specific:

When the terminal in the inactive state performs the cell selection or reselection, the first cell in the blacklist is ignored, that is, the first cell in the blacklist is not used as the candidate cell.

It should be noted that, in the embodiment of the present invention, the RRC dedicated signaling takes precedence over the system message, that is, if the RRC signaling provides a dedicated blacklist, the inactive terminal can ignore the blacklist in the system message.

The embodiment of the present invention provides a cell selection method, which is mainly for a terminal in an inactive state, and the network device sends a first indication information to the terminal, where the first indication information is used to indicate that the terminal in the inactive state is allowed or disabled to select the first cell. Therefore, the terminal in the inactive state can determine the candidate cell of the inactive cell according to the indication of the first indication information when the cell is selected and reselected, thereby enabling the terminal in the inactive state to be as capable as possible Select a cell that supports the inactive state and/or the UE AS context is valid.

Correspondingly, the opposite terminal receives N RNA identifiers.

It should be noted that there is no obvious sequence of steps between S301 and S302 in the embodiment of the present invention. S302 may be performed before S301, may be performed after S301, or may be performed simultaneously with S301, which is not limited by the present invention. .

Optionally, in the embodiment of the present invention, the network device is configured to provide the RNA configuration information of the terminal in the inactive state to the terminal in the inactive state, where the RNA configuration information includes N RNA identifiers.

In the embodiment of the present invention, if the K RNA identifiers include the X RNA identifiers of the N RNA identifiers, the first indication information is used to indicate that the terminal that allows the inactive state selects the first cell, where the first cell is the A cell corresponding to X RNAs.

In the embodiment of the present invention, if the K identifiers do not include any of the RNA identifiers, the first indication information is used to indicate that the terminal that prohibits the inactive state selects the first cell, where the first cell is a cell corresponding to the K RNAs. ; K, N, and X are positive integers, and K and N are greater than or equal to X.

It should be noted that the number of K and M in the embodiment of the present invention may be the same or different, and the present invention does not limit this.

For example, the above RNA identifier takes the RNA ID as an example, assuming that the first indication information includes two RNA IDs, and the two RNA IDs are 7 and 10 respectively, and the network device is configured with 3 RNAs for the inactive terminal. ID, the three RNA IDs are 1, 2, and 7, respectively. Since the first indication information and the RNA ID of the terminal device of the network device include RNA ID=7, the first indication information may be used by default to indicate that the terminal that allows the inactive state selects the cell corresponding to the RNA with RNA ID=7. Whereas the RNA ID=10 is not in the RNA ID of the terminal device, the first indication information may be used by default to indicate that the terminal that prohibits the inactive state selects the cell corresponding to the RNA with the RNA ID=10.

S303. The terminal determines, according to the first indication information, a candidate cell of the terminal in an inactive state.

The candidate cell is a part or all of the cells in the first cell.

In this form, in the process of performing cell selection or reselection by the corresponding inactive terminal, different operations are performed according to different roles of the first indication information. specific:

The inactive terminal considers the cell containing the RNA ID of the RNA ID configured by the network device as the candidate cell as the candidate cell, or the terminal in the inactive state does not configure the terminal not configured in the network device for a period of time. The cell of the RNA ID of the RNA ID is considered as a candidate cell.

S401. The network device is a configuration parameter configured by the terminal.

Correspondingly, the peer terminal receives the configuration information.

It should be noted that there is no obvious step sequence between S401 and S402 in the embodiment of the present invention, and 402 may be performed before S401, or may be performed after S401, or may be performed simultaneously with S401, which is not limited by the present invention. .

The configuration parameter in the embodiment of the present invention is used for cell reselection in an inactive state, and the configuration information includes at least one of the following: a frequency priority, a frequency offset, and a cell-specific offset. When the configuration parameters include: a frequency priority, a frequency offset, and a cell-specific offset, the configuration parameter is further used to calculate each of a serving cell in which the terminal in the inactive state is currently camped and a neighboring cell of the serving cell.

If the network device configures only one set of configuration information for the terminal, the cell in the idle state and the cell in the inactive state are selected/reselected. The parameter value configuration is exactly the same. If the network device configures two sets of configuration information for the terminal, the parameter selection configuration part of the cell selection/reselection of the idle state terminal and the inactive terminal terminal is the same or completely different.

In an example, the configuration parameters described above include at least one of: an intra-RAT (NR or LTE) frequency priority, a frequency offset, a cell-specific offset, and/or an inter-RAT ( LTE or NR) at least one of a frequency priority, a frequency offset, and a cell-specific offset.

Correspondingly, the opposite terminal receives the first indication information.

S403. The terminal determines, according to the configuration parameter and the first indication information, a candidate cell of the terminal in the inactive state.

The candidate cell is a part or all of the cells in the first cell.

In the embodiment of the present invention, the terminal in the inactive state performs the cell reselection process, and may be based on the frequency priority of the neighboring cell of the serving cell where the terminal currently camped in the inactive state and the currently resident service of the inactive terminal. The frequency priority of the cell is different, and different operations are performed.

Optionally, in the embodiment of the present invention, if the configuration parameter includes a frequency priority, and the frequency priority of the second cell is greater than or equal to the frequency priority of the serving cell, the first indication information is used to indicate that the terminal is inactive. The first cell is selected, where the first cell is a second cell, and the second cell is at least one of neighbor cells of a serving cell in which the terminal in the inactive state is currently camped.

Step A1: If some or all of the RNA IDs broadcast by the high-priority frequency cell or the same-level priority frequency cell are included in the RNA ID configured by the network device for the terminal, the terminal in the inactive state will be the cell corresponding to the partial or complete RNA ID. Considered as a candidate cell.

Step A2: The terminal in the inactive state considers the cell corresponding to the part or all of the RNA IDs as the candidate cell, and further calculates whether the cell channel quality meets the preset reselection criterion based on the priority parameter. For example, the channel quality of the high priority frequency cell is greater than a preset threshold and the duration exceeds a preset threshold.
