FIG. 1 is a schematic flow chart of a method for determining a reselection priority according to an embodiment of the present disclosure. The reselection priority determination method shown in this embodiment can be executed by a terminal, which includes but is not limited to communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal can communicate with network side equipment, which includes but is not limited to network side equipment in 4G, 5G, 6G and other communication systems, such as base stations, core networks, etc.

As shown in Figure 1, the reselection priority determination method may include the following steps:

In step S101, the cell reselection priority related to the inactive multicast service is determined based on the determination information of the cell reselection priority related to the inactive multicast service.

It should be noted that the cell reselection priority may include at least one of the following: frequency point priority and cell priority. When the terminal performs cell reselection, it can select a frequency point according to the priority of the frequency point, for example, select a frequency point according to the priority from high to low; it can also select a cell according to the priority of the cell (for example, in the cell corresponding to the selected frequency point ), for example, select cells according to priority from high to low.

In one embodiment, the determination information includes at least one of the following: reselection priority configuration of cell reselection priority; determination strategy of cell reselection priority.

Wherein, the determination strategy is a strategy for determining cell reselection priority, and is used to instruct the terminal how to determine cell reselection priority. For example, the reselection priority strategy includes at least one of the following: a first determination strategy for the terminal to determine the cell reselection priority, that is, the terminal determines the cell reselection priority independently; the terminal determines the cell reselection priority based on the reselection priority sent by the network device. Configure a second determination strategy for determining the cell reselection priority, that is, the terminal determines the cell reselection priority according to the reselection priority configuration.

The priority configuration is a configuration used to determine the cell reselection priority, which is the cell reselection priority or information related to the cell reselection priority, and is used for the terminal to determine the cell reselection priority. For example, the reselection priority configuration includes at least one of the following: the reselection priority configuration carried by the System Information Blocks (SIB) message; the reselection priority configuration carried by the Radio Resource Control Release RRCRelease message.

According to this embodiment, when there are multiple determination strategies, the terminal can select an appropriate determination strategy to determine the cell reselection priority related to the inactive multicast service, and then can perform cell reselection based on the determined cell reselection priority. Reselect operation.

And according to this embodiment, when there are multiple reselection priority configurations, the terminal can determine the cell reselection priority related to the inactive multicast service according to the appropriate reselection priority configuration, and further can determine the cell reselection priority according to the determined cell Reselect priority to perform cell reselection operation.

Subsequently, several embodiments will be used to specifically describe how the terminal selects and determines the policy, and how the terminal selects the reselection priority configuration.

Figure 2 is a schematic diagram illustrating yet another cell reselection method according to an embodiment of the present disclosure. As shown in Figure 2, determining the cell reselection priority related to the inactive multicast service based on the determination information of the cell reselection priority related to the inactive multicast service includes:

In step S201, in response to receiving the reselection priority configuration sent by the network device (the reselection priority configuration may be carried in the SIB or in the RRCrelease message), according to the first determination policy and/or Or the second determination strategy determines the cell reselection priority.

In one embodiment, when the terminal receives the reselection priority configuration sent by the network device, the terminal can determine the cell reselection priority according to the second determination policy, that is, the terminal can determine the cell reselection priority based on the reselection priority configuration sent by the network device. Cell reselection priority.

In one embodiment, when the terminal receives the reselection priority configuration sent by the network device to perform cell reselection, it can still determine the cell reselection priority according to the first determination policy, that is, the terminal independently determines the cell reselection priority. , and perform cell reselection according to the independently determined cell reselection priority. If cell reselection based on the independently determined cell reselection priority fails to successfully select a suitable cell, the terminal enters the any cell selection state.

In one embodiment, when receiving the reselection priority configuration sent by the network device, the terminal may determine the cell reselection priority according to the first determination strategy and/or determine the cell reselection priority according to the second determination strategy. That is, when the terminal receives the reselection priority configuration sent by the network device, the terminal can choose whether to independently determine the cell reselection priority or determine the cell reselection priority based on the reselection priority configuration sent by the network device. , or combine the two strategies to determine the cell reselection priority. For example, if the terminal fails to determine the reselection priorities of all cells based on the reselection priority configuration, then the terminal can independently determine the cell reselection priorities for cells whose reselection priorities have not been determined.

In one embodiment, determining the cell reselection priority related to the inactive multicast service based on the determination information of the cell reselection priority related to the inactive multicast service includes: responding to the failure to receive The cell reselection priority is determined according to the first determination policy according to the reselection priority configuration sent by the network device.

When the terminal performs cell reselection, if it fails to receive the reselection priority configuration sent by the network device, the terminal can determine the cell reselection priority according to the first determination strategy, that is, the terminal can independently determine the cell reselection priority, and Cell reselection is performed according to the independently determined cell reselection priority.

Among them, the terminal can independently determine that the priority of all frequencies that support inactive multicast services is higher than the priority of frequencies that do not support inactive multicast services, so that the terminal can reselect the priority according to the independently determined cell. When performing cell reselection, priority can be given to reselecting frequencies that support inactive multicast services;

The terminal can independently determine that the priority of all cells that support inactive multicast services is higher than the priority of cells that do not support inactive multicast services, so that the terminal can perform cell reselection based on the independently determined cell reselection priorities. In this case, cells that support inactive multicast services can be reselected preferentially.

In one embodiment, the terminal can also determine the cell reselection priority completely independently, that is, regardless of whether the terminal receives the reselection priority configuration sent by the network device, the terminal can directly determine the cell reselection priority independently according to the first determination policy. class.

Figure 3 is a schematic diagram illustrating yet another cell reselection method according to an embodiment of the present disclosure. As shown in Figure 3, determining the cell reselection priority related to the inactive multicast service based on the determination information of the cell reselection priority related to the inactive multicast service includes:

In step S301, in response to receiving the reselection priority configuration carried by the RRCRelease message and the SIB message, the cell reselection priority is determined according to the reselection priority configuration carried by the RRCRelease message and/or the SIB message.

Wherein, the reselection priority configuration carried by the RRCRelease message includes at least one of the following: a reselection priority of a first cell that supports inactive multicast services; a second cell that does not support inactive multicast services. Reselection priority; cell reselection parameters associated with the inactive multicast service, the cell reselection parameters are used to determine the cell reselection order of the inactive multicast service; traditional legacy cell reselection priority .

The reselection priority configuration carried by the SIB message includes at least one of the following: traditional legacy cell reselection priority; cell reselection parameters associated with inactive multicast services.

The reselection priority of the first cell that supports the inactive multicast service may include the priority of the first frequency point that supports the inactive multicast service and/or the priority of the first cell that supports the inactive multicast service. level; the reselection priority of the second cell that does not support the inactive multicast service may include the priority of the second frequency point that does not support the inactive multicast service and/or the priority of the second cell that does not support the inactive multicast service. This disclosure does not limit the priority of the second cell.

The cell reselection parameters are used to determine the cell reselection sequence of the inactive multicast service. For example, the terminal determines the R value of each candidate cell that meets the cell reselection conditions based on the R criterion, and determines the reselection order of the candidate cells based on the relationship between the R values of each candidate cell. The cell reselection parameters can be used to The parameters in the R criterion are adjusted.

In related technologies, when a terminal performs cell reselection, the terminal can calculate the R value of each candidate cell through the cell ranking criterion (R criterion), and then sort the candidate cells based on the relationship between the R values of each candidate cell to determine the cell. Reselect order. Specifically, the calculation formula for calculating the R value of each candidate cell through the R criterion is as follows:

Rs=Qmeas,s+Qhyst-Qoffsettemp;

Rn=Qmeas,n-Qoffset-Qoffsettemp;

Among them, Rs represents the R value of the serving cell, Rn represents the R value of the neighboring cell, Qmean,s represents the reference signal receiving power RSRP (Reference Signal Receiving Power) of the serving cell, Qhyst represents the reselection hysteresis parameter of the serving cell, and Qoffsettemp represents R The offset parameter added in the criterion when multiple random access failures occur, Qoffset represents the offset value of the neighboring cell, and Qoffsettemp and Qoffset are both carried by the network equipment and broadcast in the system message.

For cells related to the inactive multicast service, the terminal can determine the first reselection priority of the first cell that supports the inactive multicast service based on the received cell reselection parameters. Taking the R criterion as an example, when calculating the R value of the first cell that supports inactive multicast services, cell reselection parameters can be introduced based on the original parameters in the R value calculation formula of related technologies to increase support. The R value of the first cell of the inactive multicast service, thereby improving the ranking of cell reselection. As a possible implementation, the calculation formula for calculating the R value of the first cell through the R criterion is as follows:

Rs=Qmeas,s+Qhyst-Qoffsettemp+Qoffsetmulticast (Equation 1);

Rn=Qmeas,n-Qoffset-Qoffsettemp+Qoffsetmulticast (Formula 2);

Among them, Qoffsetmulticast is the cell reselection parameter associated with the inactive multicast service.

In one embodiment, the terminal can no longer use Qoffset and Qoffsettemp when calculating the R value, but can directly calculate Rs based on Qmeas,s, Qhyst and cell reselection parameters, and calculate the Rn value based on Qmeas,n and cell reselection parameters.

Calculating the cell reselection order of cells related to the inactive multicast service based on the cell reselection parameters associated with the inactive multicast service can make the first cell that supports the inactive multicast service be better than the first cell that does not support the inactive multicast service. The second cell with active multicast service is ranked relatively high in the cell reselection, so that the terminal can be reselected to a cell that supports inactive multicast service first during cell reselection, which is helpful to ensure that the terminal can be reselected. Perform inactive multicast services in the cell.

When the terminal receives multiple reselection priority configurations sent by the network device, the terminal may determine the reselection priority configuration among the multiple received reselection priority configurations according to the type of message carrying the reselection priority configuration. Reselection priority configuration of cell reselection priority.

In one embodiment, when the terminal receives the reselection priority configuration carried by the RRCRelease message and the SIB message, the terminal may determine the cell reselection priority only based on the reselection priority configuration carried by the RRCRelease message.

In one embodiment, the terminal receives the cell reselection parameters associated with the inactive multicast service carried by the RRCRelease message and the cell reselection parameters associated with the inactive multicast service carried by the SIB message. In this case, the cell reselection sequence can be determined only based on the cell reselection parameters carried in the RRCRelease message.

In one embodiment, when the terminal receives the first cell reselection priority that supports the inactive multicast service carried by the RRCRelease message and the traditional legacy cell reselection priority carried by the SIB message, it can only Cell reselection is performed based on the priority of the first cell that supports the inactive multicast service carried in the RRCRelease message. If cell reselection fails to successfully reselect a suitable cell based on the priority of the first cell that supports inactive multicast services, the terminal enters any cell selection state.

In one embodiment, when the terminal receives the first cell reselection priority that supports inactive multicast services and the second cell reselection priority that does not support inactive multicast services carried by the RRCRelease message, and is sent by In the case of the traditional legacy cell reselection priority carried in the SIB message, cell reselection may be performed only based on the priority of the first cell and the priority of the second cell carried in the RRCRelease message. If cell reselection based on the priority of the first cell and the priority of the second cell fails to successfully select a suitable cell, the terminal enters the any cell selection state.

In one embodiment, when the terminal receives the legacy cell reselection priority carried by the RRCRelease message and the legacy cell reselection priority carried by the SIB message, the terminal may only perform the reselection based on the legacy cell reselection priority carried by the RRCRelease message. Traditional legacy cell reselection priority is used for cell reselection. If cell reselection based on the traditional legacy cell reselection priority fails to successfully select a suitable cell, the terminal enters the any cell selection state.

In one embodiment, in response to receiving the reselection priority configuration carried by the RRCRelease message and the SIB message, the terminal may first determine the cell reselection priority according to the reselection priority configuration carried by the RRCRelease message and perform cell reselection. If the cell reselection fails to be successfully reselected to a cell based on the cell reselection priority determined by the reselection priority configuration carried by the RRCRelease message, the cell reselection is further determined based on the reselection priority configuration carried by the SIB message. Select priority.

In one embodiment, when the terminal receives the priority of the first cell supporting the inactive multicast service carried by the RRCRelease message and the reselection priority of the traditional legacy cell carried by the SIB message, the terminal can first select the RRCRelease message. The priority of the first cell that supports the inactive multicast service carried in the cell reselection is performed. If a suitable cell cannot be successfully selected based on the priority of a cell that supports inactive multicast services, the terminal can reselect the priority based on the traditional legacy cell carried in the SIB message to determine that inactive multicast is not supported. The cell reselection priority of the service is used to perform cell reselection. If the appropriate cell is still not successfully selected, the terminal will enter the any cell selection state.

According to the above embodiment, when the terminal receives the reselection priority configuration carried by the RRCRelease message and the SIB message, it preferentially chooses to determine the reselection of the inactive multicast service according to the reselection priority configuration carried in the RRCRelease message. Priority, cell reselection is performed.

Since the RRCRelease message is sent through the RRC connection, the reselection priority configuration carried in the RRCRelease message is usually more targeted than the reselection priority configuration carried in the SIB message sent by the network device through broadcast. Therefore, when performing cell reselection for cells related to inactive multicast services, the reselection priority of the inactive multicast service can be determined by preferentially selecting the reselection priority configuration carried in the RRRRCelease message, so that the determined inactive multicast service can be reselected. The reselection priority of active multicast services is more accurate.

And when the cell reselection priority determined based on the reselection priority configuration carried in the RRCRelease message is not successfully reselected to the cell, further targeting of the cell and/or frequency not configured in the RRCRelease message can be carried out. point, apply the reselection priority configuration carried in the SIB message to determine the cell reselection priority. Accordingly, the cell reselection priority determined according to the SIB cell can be applied for cell reselection, so that the cell can be successfully reselected.

In one embodiment, determining the cell reselection priority related to the inactive multicast service based on the determination information of the cell reselection priority related to the inactive multicast service includes: in response to receiving The cell reselection priority is determined based on the reselection priority configuration carried by the RRCRelease message. That is, when the terminal only receives the reselection priority configuration carried in the RRCRelease message, the terminal can directly determine the cell reselection priority based on the reselection priority configuration carried in the RRCRelease message.

In one embodiment, determining the cell reselection priority related to the inactive multicast service based on the determination information of the cell reselection priority related to the inactive multicast service includes: in response to receiving The cell reselection priority is determined according to the reselection priority configuration carried by the SIB message. That is, when the terminal only receives the reselection priority configuration carried in the SIB message, the terminal can directly determine the cell reselection priority based on the reselection priority configuration carried in the SIB message.

In one embodiment, when determining the cell reselection priority, the terminal may first determine the cell reselection priority determination strategy related to the inactive multicast service. After determining the cell reselection priority determination strategy, the terminal determines the cell reselection priority. When the second determination strategy of the cell reselection priority is determined based on the reselection priority configuration sent by the network device, the reselection priority configuration of the cell reselection priority related to the inactive multicast service is further determined, thereby The cell reselection priority is determined according to the determined reselection priority configuration.

For example, when the terminal receives the priority of the first cell supporting the inactive multicast service sent by the network device in the RRCRelease message and the reselection priority of the traditional legacy cell sent in the SIB message, the terminal can First, in response to receiving the reselection priority configuration sent by the network device, it is determined that the cell reselection priority is determined through the second determination strategy. Further, when it is determined that the cell reselection priority is determined through the second determination strategy, the terminal may respond to receiving the reselection priority configuration carried by the RRCRelease message and the SIB message, and determine the reselection priority carried by the RRCRelease message. The priority configuration determines the cell reselection priority, that is, the terminal can use the priority of the first cell that supports inactive multicast services carried in RRCRelease as the cell reselection priority.

The second cell reselection priority; the cell reselection parameters associated with the inactive multicast service, the cell reselection parameters are used to determine the cell reselection sequence of the inactive multicast service; the traditional legacy cell Reselect priorities.

The cell reselection parameters are used to determine the cell reselection sequence of the inactive multicast service. For example, the terminal determines the R value of each candidate cell that meets the cell reselection conditions based on the R criterion, and determines the reselection order of the candidate cells according to the relationship between the R values of each candidate cell. The cell reselection parameters can be used to The parameters in the R criterion are adjusted.
