Description

Slice management method, base station and terminal

Technical Field

The present invention relates to the field of communications, and in particular, to a slice management method, a base station, and a terminal.

Background

A New concept of slicing is introduced into a 5G NR (New RAT) system, different slice types correspond to different service types, and an operator can flexibly configure the supported network slice types on a network side according to the requirements of the operator. In order to improve the flexibility of slice deployment on the network side to the maximum extent, the slice types deployed in different frequency point cells support independent configuration. At present, the cell reselection between cells with the same frequency does not need to consider the limitation of network slices, and under the background of network deployment slices, the UE performing the inter-frequency cell reselection or handover can preferably perform reselection or handover to the inter-frequency cell supporting the service thereof, otherwise the UE has the possibility of frequently performing the inter-frequency cell reselection or handover, and even has the possibility of service interruption of the connected UE under extreme conditions.

In a scene of slice deployment in a network, different slices can be deployed at different frequency points, and slices supported at the same frequency point are the same. That is, there is a certain correspondence between slices and frequency points. Thus, when the base station knows the slice information that the UE is currently allowed to access, it can configure a dedicated cell reselection priority for the UE based on this information. When the UE enters an idle state, the UE reselects based on the cell reselection priority configured by the base station, so as to ensure that the target cell selected by the UE also supports the slice currently allowed to be accessed by the UE. When the UE initiates access in the cell, the UE carries slice information that the UE desires to access, so that the base station can access the UE to its desired slice and provide corresponding services.

However, in the prior art, there is a precondition in the use method of slices that the slices of the wireless side/base station are considered to be always available. Therefore, as long as the UE performs cell reselection based on the reselection priority configured by the network, the UE will not camp on a base station that does not support the UE slice. So that a subsequent UE can always initiate an access procedure to access its desired slice to receive service. In practice, however, slices of the wireless side/base station are not always available, possibly due to software and hardware upgrades or network anomalies, resulting in some slices being temporarily unavailable.

Because the network slice is also temporarily unavailable, even if the UE performs cell reselection on the same frequency and different frequencies based on the dedicated cell reselection priority information configured by the network, the situation that a slice supported by a certain base station is temporarily unavailable may still exist, which causes the UE to fail when the base station accesses the desired slice, and the UE cannot know that the desired slice is temporarily unavailable, and thus frequently initiates unnecessary access, and increases system overhead.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

In some embodiments of the present invention, referring to fig. 1, there is provided a slice management method including:

step 101, receiving an access request sent by a terminal, where the access request includes a target slice that the terminal desires to access.

Here, the network side receives the access request sent by the terminal, and when the terminal UE initiates the access request, the terminal UE carries the target slice information desired to be accessed, so that the network side can access the UE to the desired target slice and provide corresponding services.

And 102, when determining that the service of the target slice cannot be provided, sending a notification message of the service of the target slice cannot be provided to the terminal.

Here, slices on the network side are not always available, possibly due to software and hardware upgrades or network anomalies, resulting in some slices being temporarily unavailable. When the network side determines that the service of the target slice cannot be provided, the notification message of the service of the target slice cannot be provided is sent to the UE, so that the UE can access other slices as soon as possible, and unnecessary access is avoided being frequently initiated.

According to the slice management method provided by the embodiment of the invention, when the network side determines that the service of the target slice cannot be provided, the notification message of the service of the target slice cannot be provided is sent to the terminal, so that the terminal can know that the target slice which the terminal wants to access is temporarily unavailable, the terminal can access other slices as soon as possible, the user experience is improved, the frequent initiation of unnecessary access is avoided, and the system overhead is reduced.

Optionally, the step 102 includes:

step 1021, when it is determined that the service of the target slice cannot be provided, releasing the radio resource of the terminal, and sending a release message to the terminal, where the release message carries a release reason, and the release reason is that the target slice is temporarily unavailable or cannot support the target slice.

Here, when the UE accesses the network side, the network side is notified of the target slice that the UE desires to access, and when the network side determines that the service of the target slice cannot be provided, the network side releases the radio resource of the UE and also notifies the UE that the target slice is temporarily unavailable or cannot support the target slice, so that the UE can know that the target slice is temporarily unavailable or cannot support the target slice, so that the UE can access other slices as soon as possible, and avoid frequently initiating unnecessary access. The notification message is specifically a release message.

The release message may be, for example, an RRC (Radio Resource Control) connection release message.

Optionally, the step 102 includes:

step 1022, when it is determined that the service of the target slice cannot be provided, rejecting the access request of the terminal, and sending a rejection message to the terminal, where the rejection message carries a rejection reason, and the rejection reason is that the target slice is temporarily unavailable or cannot support the target slice.

Here, when the UE accesses the network side, the network side is notified of the target slice that the UE desires to access, and when the network side determines that the service of the target slice cannot be provided, the network side rejects the UE, and at the same time, the UE is notified that the rejection reason is that the target slice is temporarily unavailable or cannot support the target slice, so that the UE can know that the target slice is temporarily unavailable or cannot support the target slice, so that the UE can access other slices as soon as possible, and frequent initiation of unnecessary access is avoided. The notification message is now specifically a reject message.

The reject message may be, for example, an RRC (Radio Resource Control) connection reject message.

and 103, sending a timer for temporarily unavailable slices to the terminal, so that the terminal performs cell reselection according to the timer.

Here, when the network side determines that the service of the target slice cannot be provided, a notification message that the service of the target slice cannot be provided is sent to the UE, and meanwhile, a timer that the slice is temporarily unavailable may also be sent, so that the UE may perform cell reselection according to the timer.

When the notification message is specifically a release message, a release reason and/or a timer for temporarily making the slice unavailable may be carried in the release message. When the notification message is specifically a reject message, a reject reason and/or a timer when the slice is temporarily unavailable may be carried in the reject message.

When the release message only carries the release reason or the reject message only carries the reject reason, after receiving the release message or the reject message, the UE may reselect the cell with the current frequency point as the lowest priority, so that the UE may not select the temporarily unavailable target slice, but access other slices as soon as possible, thereby improving user experience and avoiding unnecessary access.

When the release message carries a timer for temporarily not using the release reason and the slice at the same time, or the reject message carries a timer for temporarily not using the reject reason and the slice at the same time, after the UE receives the release message or the reject message, the UE can modify the priority of the current frequency point into the lowest priority and then reselect the cell before the timer is overtime, so that the UE cannot select the target slice which is temporarily not used, and access other slices as soon as possible, thereby improving the user experience and avoiding unnecessary access; after the timer is overtime, the UE can restore the priority of the current frequency point to the priority before modification and then perform cell reselection, so that the UE can be ensured to be normally accessed to a target slice.

In the embodiment of the present invention, the specific execution process of the cell reselection performed by the UE based on the priority of the frequency point is not limited, and any known manner may be used.

Further, after sending the timer for temporarily not using the slice to the terminal, the method further includes:

and 104, sending the frequency point priority information configured for the terminal to the terminal, so that the terminal performs cell reselection according to the timer and the frequency point priority information.

Here, when the network side determines that the service of the target slice cannot be provided, a notification message of the service of the target slice cannot be provided is sent to the UE, and meanwhile, a timer for temporarily unavailable slicing and frequency point priority information configured for the UE can also be sent, so that the UE can perform cell reselection according to the timer and the frequency point priority information.

The step 104 may be executed before the step 103, or may be executed simultaneously with the step 103. That is, the network side may first send the timer for temporarily making the slice unavailable to the terminal, and then send the frequency point priority information configured for the terminal to the terminal, or first send the frequency point priority information configured for the terminal, and then send the timer for temporarily making the slice unavailable to the terminal, or both of them.

As described above, when the notification message is specifically a release message, the release message may carry a release reason and/or a timer that a slice is temporarily unavailable, and send frequency point priority information. When the notification message is a reject message, the reject message may carry a reject reason and/or a timer for which the slice is temporarily unavailable, and send the frequency point priority information.

When the release message carries a timer for temporarily unavailable release reasons and slices at the same time or the reject message carries a timer for temporarily unavailable reject reasons and slices at the same time, after the UE receives the release message or the reject message, the UE can use the frequency point priority information configured on the network side to reselect the cell before the timer is overtime, and the frequency point corresponding to the target slice in the preferred frequency point priority information is not the highest priority, so that the UE cannot select the temporarily unavailable target slice and accesses other slices as soon as possible, the user experience is improved, and unnecessary access is avoided; after the timer is overtime, the UE can modify the priority of the current frequency point into the highest priority and then reselect the cell, or reselect the cell by using the frequency point priority information configured by the network, thereby ensuring that the UE can normally access the target slice.

In summary, as an optional implementation manner, when the UE accesses the network side, the network side is notified of the target slice that the UE desires to access, and when the network side determines that the service of the target slice cannot be provided, the UE may be released through the RRC connection release message, and the release reason carried in the release message is that the target slice is temporarily unavailable or cannot support the target slice. Further, the network side may also carry a timer that the slice is temporarily unavailable in the release message. If the release message only has a release reason and no timer for temporarily unavailable slices exists, the UE can perform cell reselection by taking the current frequency point as the lowest priority after receiving the release message. If the release message contains the release reason and also contains a timer for temporarily making the slice unavailable, there are two processing modes:

1) after receiving the release message, the UE modifies the priority of the current frequency point to the lowest priority before the timer is overtime and then performs cell reselection, and recovers the priority of the current frequency point to the priority before modification after the timer is overtime and then performs cell reselection.

2) After receiving the release message, the UE performs cell reselection according to the frequency point priority information configured on the network side before the timer is overtime, and performs cell reselection after modifying the priority of the current frequency point to the highest priority after the timer is overtime, or performs cell reselection according to the frequency point priority information configured on the network.

As another optional implementation manner, when the UE accesses the network side, the network side is notified of the target slice that the UE desires to access, and when the network side determines that the service of the target slice cannot be provided, the network side may reject the UE through the RRC connection reject message, and carry the reject reason in the reject message as the target slice is temporarily unavailable or cannot support the target slice. Further, the network side may also carry a timer that the slice is temporarily unavailable in the reject message. If the reject message only has reject reasons and no timer for temporarily unavailable slices, the UE receives the reject message and then performs cell reselection by taking the current frequency point as the lowest priority. If the reject message contains a reject reason and also contains a timer for temporarily making the slice unavailable, two processing modes are provided:

1) after receiving the rejection message, the UE modifies the priority of the current frequency point to the lowest priority before the timer is overtime and then performs cell reselection, and recovers the priority of the current frequency point to the priority before modification after the timer is overtime and then performs cell reselection.

2) After receiving the rejection message, the UE performs cell reselection according to the frequency point priority information configured on the network side before the timer times out, and performs cell reselection after modifying the priority of the current frequency point to the highest priority after the timer times out, or performs cell reselection according to the frequency point priority information configured on the network.

To sum up, according to the slice management method of the embodiment of the present invention, when the network side determines that the service of the target slice cannot be provided, a notification message that the service of the target slice cannot be provided is sent to the terminal, so that the terminal can know that the target slice which the terminal desires to access is temporarily unavailable, the terminal can access other slices as soon as possible, user experience is improved, frequent initiation of unnecessary access is avoided, and system overhead is reduced.

In some embodiments of the present invention, referring to fig. 4, there is also provided a slice management method, including:

step 401, sending an access request to a network side, where the access request includes a target slice that a terminal desires to access.

Specifically, the step 405 includes:

step 4051, before the timer is overtime, the priority of the current frequency point is modified to the lowest priority, and then cell reselection is performed.

Here, before the timer is overtime, the UE modifies the priority of the current frequency point to the lowest priority and then performs cell reselection, so that the UE does not select a target slice that is temporarily unavailable, but accesses other slices as soon as possible, thereby improving user experience and avoiding unnecessary access.

Step 4052, after the timer is overtime, the current frequency point is restored to the priority before modification, and then cell reselection is performed.

After the timer is overtime, the UE restores the priority of the current frequency point to the priority before modification and then performs cell reselection, so that the UE can be ensured to be normally accessed to the target slice.

When the notification message is specifically a release message, the network side may carry a release reason and/or a timer that the slice is temporarily unavailable in the release message. When the notification message is specifically a reject message, the network side may carry a reject reason and/or a timer when the slice is temporarily unavailable in the reject message.

When the release message only carries the release reason or the reject message only carries the reject reason, after receiving the release message or the reject message, the UE can reselect the cell by taking the current frequency point as the lowest priority, and when the release message simultaneously carries the release reason and a timer for temporarily unavailable slices, or the reject message simultaneously carries the reject reason and the timer for temporarily unavailable slices, after receiving the release message or the reject message, the UE can modify the priority of the current frequency point into the lowest priority and reselect the cell before the timer is overtime; after the timer is overtime, the cell reselection can be performed after the priority of the current frequency point is restored to the priority before modification.

Optionally, after the step 404, the method further includes:

step 406, receiving frequency point priority information configured for the terminal sent by a network side;

step 407, reselecting the cell according to the timer and the frequency point priority information.

At this time, when the network side determines that the service of the target slice cannot be provided, a notification message of the service of the target slice cannot be provided is sent to the UE, and simultaneously, a timer that the slice is temporarily unavailable and frequency point priority information configured for the UE can also be sent, and the UE receives the timer and the frequency point priority information sent by the network side and can perform cell reselection according to the timer and the frequency point priority information.

The network side can send a timer for temporarily unavailable slicing to the terminal, and then send the frequency point priority information configured for the terminal to the terminal, or send the frequency point priority information configured for the terminal to the terminal, and then send the timer for temporarily unavailable slicing to the terminal, or send the timer for temporarily unavailable slicing to the terminal and the timer for temporarily unavailable slicing to the terminal. Correspondingly, the terminal can receive the timer with the temporarily unavailable slice first and then receive the priority information of the frequency point, or receive the priority information of the frequency point first and then receive the timer with the temporarily unavailable slice, or receive the timer with the temporarily unavailable slice first and then receive the timer with the temporarily unavailable slice simultaneously. I.e. the above-mentioned step 406 may also be performed before step 404 or simultaneously with step 404.

Specifically, the step 407 includes:

step 4071, before the timer is overtime, performing cell reselection according to the frequency point priority information.

Here, before the timer is overtime, the frequency point priority information configured on the network side is used for cell reselection, and the frequency point corresponding to the target slice in the preferred frequency point priority information is not the highest priority, so that the UE cannot select the temporarily unavailable target slice and accesses other slices as soon as possible, user experience is improved, and unnecessary access is avoided.

Step 4072, after the timer is overtime, the priority of the current frequency point is modified to the highest priority, and then cell reselection is performed, or cell reselection is performed according to the frequency point priority information.

Here, after the timer is overtime, the UE may modify the priority of the current frequency point to the highest priority and then perform cell reselection, or perform cell reselection using the priority information of the frequency point configured by the network, so as to ensure that the UE can normally access the target slice.

As described above, when the notification message is specifically a release message, the network side may carry a release reason and/or a timer for which a slice is temporarily unavailable in the release message, and send frequency point priority information. When the notification message is a reject message, the network side may carry a reject reason and/or a timer for which the slice is temporarily unavailable in the reject message, and send the frequency point priority information.

When the release message simultaneously carries a release reason and a timer for temporarily unavailable slices, or the reject message simultaneously carries a reject reason and a timer for temporarily unavailable slices, after receiving the release message or the reject message, the UE can use the frequency point priority information configured on the network side to reselect the cell before the timer is overtime; after the timer is overtime, the UE can modify the priority of the current frequency point to the highest priority and then reselect the cell, or reselect the cell by using the priority information of the frequency point configured by the network.

To sum up, according to the slice management method of the embodiment of the present invention, when the network side determines that the service of the target slice cannot be provided, a notification message that the service of the target slice cannot be provided is sent to the terminal, and the terminal receives the notification message sent by the network side, so that the terminal can know that the target slice which the terminal desires to access is temporarily unavailable, and can access other slices as soon as possible, thereby improving user experience, avoiding frequent initiation of unnecessary access, and reducing system overhead.
