detailed description

The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 1 , this embodiment provides a network slicing application control method, which is applied to a base station, and includes: distributing slice configuration information of a radio access network to a UE.

The base station in this embodiment may be various types of base stations, for example, network elements applied to the RAN side in evolved base stations (eNBs), next-generation base stations (gNBs), and the like.

In this embodiment, the base station sends the slice configuration information to the UE, and the slice configuration information is a policy for the RAN to manage and control the availability of network slices. For example, the base station may form the slice configuration information according to information such as current available resource status on the RAN side, signal quality, and load rates of different resources.

For example, the base station may send the slice configuration information to the UE in a broadcast manner, a multicast manner or a unicast manner. In this way, the UE can receive the slice configuration information sent by the base station of the cell where it is currently located. In this way, when the UE needs to use a certain network slice for a session, it will select the network slice for the session based on the slice configuration information. In short, in this embodiment, the base station realizes the availability management and control of network slices by sending the slice configuration information of the RAN, and avoids the single management and control of network slices by the core network (Core Network, CN). Problems such as fragmentation of network resources and inflexible deployment of network resources on the RAN side have the characteristics of high flexibility in deployment of network resources on the RAN side and high effective utilization of resources.

Optionally, the slice configuration information includes: slice information of applicable network slices and/or constraints for applying the network slices.

In this embodiment, the slice information may be indication information indicating applicable or corresponding network slices of the base station, and the slice information may be: the slice identifier of the network slice, the name of the network slice, or other directly or indirectly indicating the base station Information about applicable network slices. The slice configuration information may also include: a constraint condition for applying the network slice, the constraint condition is the condition that the UE needs to meet when using the network slice, for example, the user capability that the UE (also called a terminal) needs to provide, etc. .

The constraint conditions can be the conditions required to use the corresponding network slices. According to the content defined by the constraints, they can be divided into user capability constraints that need to be met by the user capabilities, for example, whether the terminal level is a specific level; for example, the terminal Whether a specific capability is supported (for example, whether the terminal supports dual connectivity), etc.

The constraints may also include: network status constraints, and the network status constraints may include: whether the signal quality that can be provided by the network satisfies the quality condition, and whether the resources that can be provided by the network meet the sufficient resource condition. In some embodiments, the constraint condition may further include: a subscription constraint condition, for example, whether the UE has subscribed to a condition for using a corresponding network slice.

Optionally, the constraint conditions for applying the network slicing include at least one of the following:

The network resource meets the first condition;

The network status satisfies the second condition;

The user parameter satisfies the third condition.

The network resource meeting the first condition may include:

The load of the current cell is higher than the first load threshold, and/or the load of the neighboring cell is lower than the second load threshold;

The network status meeting the second condition includes at least one of the following: the signal quality of the neighboring cells in the neighboring cell list reaches the quality threshold;

The signal quality of this cell is lower than the quality threshold;

The signal quality of the frequency band reaches the quality threshold;

The signal quality of the tracking area reaches the quality threshold;

The user type is a predetermined user type including at least one of the following;

The user parameter meeting the third condition includes at least one of the following;

The user capability meets the fourth condition;

The wireless network standard/spectrum selection priority meets the fifth condition, which may include: the user wireless network standard selection priority (RAT Selection Priority) and/or the spectrum selection priority spectrum selection priority (Frequency Selection Priority) meets the fifth condition; the user wireless The network standard selection priority and/or the spectrum selection priority may be described by an index wireless network standard/spectrum selection priority (RAT Frequency Selection Priority, RFSP).

The user slice satisfies the sixth condition;

The user's mobile behavior meets the seventh condition;

The user's business behavior satisfies the eighth condition.

For example, the user's equipment type is a predetermined equipment type, which may satisfy one of the fourth conditions of the user capability, and the user capability may include the terminal capability of the user equipment. The terminal capability can be used to describe the capability that can be realized by the user equipment. The user capability may also include: the capability of the user account, the user account may be an identifier such as the user's mobile phone number, and the capability of the user account may include: the service capability subscribed to by the user account. The above are only examples of user capabilities, but specifically, the user capabilities are not limited to the above examples. The user capability satisfies the fourth condition. The user capability may include a user capability of a specified execution type, for example, the terminal capability of the UE where the user account is located has a specified terminal capability, for example, the UE is a UE with dual connectivity capability , it can be considered that the user capability satisfies the fourth condition.

The user wireless network system selection priority is the first predetermined priority and/or the spectrum selection priority is the second predetermined priority, which may satisfy the fifth condition.

Optionally, the slice information of the applicable network slice includes at least one of the following:

A slice ID, an ID derivable from a slice ID, and an ID from which a slice ID can be derived.

The slice identifier may be an identifier such as a serial number of the network slice; it may also be a type identifier of the network slice. The identifier that can be deduced from the slice identifier can be called the first derivation identifier, and can also be the derivation information of the identifier of the network slice directly, or the derivation information of the type identifier of the network slice; the derivation information of the identifier of the slice can be derived The identifier, which may be referred to as a second derivation identifier, may also correspond to the derivation of a single network slice identifier, or the derivation of a network slice type identifier.

In some embodiments, the slice information of the applicable network slice may be indirectly indicated by information such as access type, user type, wireless network standard/spectrum selection priority or include the slice information.

Optionally, the user's equipment type is a predetermined equipment type, that is, the user equipment is a specific type of user equipment, for example, a user equipment with a dual connection function. In short, if the user equipment is a predetermined equipment type, it means Hardware resources or software resources for this device type meet certain requirements.

The user's mobile behavior meeting the seventh condition may include but not limited to:

The mobile behavior of the user is a predetermined mobile behavior. For example, whether the movement of the user equipment is within the registration area or outside the registration area, it can be divided into roaming and non-roaming mobile behavior. If the mobile behavior of the user is not a roaming behavior, the mobile behavior of the user may satisfy one of the seventh conditions.

The user's business behavior is a scheduled business behavior, which can be one of the eighth conditions that the user's business behavior meets. For example, the user equipment subscribes to the corresponding scheduled service, or the user equipment initiates a service request for a scheduled service, etc., which can be regarded as the user's business behavior. The behavior satisfies one or more of the eighth conditions.

The user slice satisfies the sixth condition, which may include: the slice used by the user or the network slice corresponding to the request for initiating a slice is a designated network slice. For another example, the sixth condition is that the network slice currently requested by the user is in the slice list (allowed network slice selection assistance information, Allowed NSSAI) allowed by the user, or the slice of the current session of the user contains one or more specified slices.

Optionally, user slices are designated network slices. The user slice includes the network slice allowed to be used by the user and/or the network slice corresponding to the slicing session currently initiated by the user.

If the network state meets the second condition, the signal quality of the cell is lower than the quality threshold; the signal quality of the neighboring cells in the neighbor list reaches the quality threshold; the signal quality of the frequency band reaches the quality threshold; the signal quality of the tracking area reaches the quality threshold. At least one of them holds. Therefore, in this embodiment, the current base station needs assistance from other base stations to form a network slice of the RAN. If the corresponding network slice needs to be used, it may be necessary to consider whether the UE can receive the signal of the corresponding auxiliary base station, or whether the signal quality is good enough.

The signal quality of the neighbor cells in the neighbor cell list reaching the quality threshold may include: the UE needs to detect the signal of the neighbor cells in the neighbor cell list, and the detected signal quality needs to reach a specific signal value.

The signal quality of the frequency band reaches the quality threshold. For example, network slice A uses frequency band A. To ensure the session quality of the UE using network slice A for the session, it is necessary to ensure that the signal quality of the UE using frequency band A for communication reaches a specific quality threshold.

In some embodiments, the constraint condition further includes that the signal quality of the tracking area reaches a quality threshold. For example, if the UE is currently in a certain tracking area, it may need to use the network slice corresponding to the tracking area. To ensure session quality, the UE needs to detect that the signal quality of signals sent by one or more base stations in the tracking area reaches the quality threshold.

In this embodiment, the quality thresholds corresponding to the signal quality of the neighboring cell list, the signal quality of the frequency band, and the signal quality of the tracking area may be the same or different, and may be specifically set according to actual needs.

In some embodiments, the signal quality reaching a quality threshold may include: signal strength reaching a strength threshold; and/or signal power reaching a power threshold. In some other embodiments, the UE detects that the signal-to-noise ratio of a signal of a neighboring cell, another cell in the tracking area, or a specific frequency reaches a preset minimum signal-to-noise ratio, or the like.

In short, in this embodiment, the signal quality can be used to measure the strength of the receiving ability of the UE's current location to receive signals from other base stations, this cell, neighboring cells, or specific frequency bands. If the receiving ability is strong, it indicates that the communication quality is good. , the network slice corresponding to the frequency band, the tracking area or the neighboring cell can be used to provide the session for the UE.

Optionally, the slice configuration information includes at least one of the following: slice configuration information of a cell list; slice configuration information of a frequency band; slice configuration information of a tracking area; slice configuration information of a user.

In this embodiment, according to the scope corresponding to the slice configuration information, slice configuration information can be divided into slice configuration information with different granularities, for example, slice configuration information at the granular level of the cell list, and the slice configuration information at the granular level of the cell list usually includes a or multiple cells, these one or more cells generally include not only the current serving cell of the UE, but also: one or more neighboring cells of the current serving cell.

The slice configuration information of the frequency band is the slice configuration information corresponding to the frequency band. For example, N frequency bands may be provided in cell A, and only M frequency bands are configured in a certain network slice, M is less than or equal to N, and both N and M can be positive integers. In this way, the application strategy of this network slice can be It is called the slice configuration information of the frequency band. The slice configuration information of the frequency band may be: the slice configuration information that needs to be followed when the UE using the frequency band selects a network slice for a session. The slice configuration information of the tracking area defines the slice configuration information in the tracking area.

Slicing configuration information of different granularities satisfies the control of the use of network slices in different geographical ranges or resource ranges on the RAN side.

The slice configuration information of the user may be slice configuration information corresponding to the user account.

Optionally, as shown in FIG. 2 , the method further includes: receiving a slice request sent by the UE based on the slice configuration information.

In this embodiment, the base station will receive the slice request sent by the UE according to the slice configuration information, and the slice request can be used for the UE to request to use the corresponding network slice for a session request, or for the UE to request an access request to access the network slice. Usually, the slice request may carry indication information indicating the corresponding network slice, for example, various indication information such as an identifier and a name of the network slice, and resource identifiers used by the network slice.

In this embodiment, the slice request sent by the UE is based on the slice configuration information sent by the RAN, which complies with the management and control of the network slice by the RAN.

Optionally, the method further includes: sending a rejection message of the slice request to the UE.

In this embodiment, if the base station wants to reject the UE's slicing request, it will send a rejection message to the UE. The rejection message can be: the network status information, the number of available resources, and the terminal Capabilities and other user capabilities issued by one or more. For example, when the load rate of the network slice requested by the UE to access or use exceeds the preset load rate, the number of remaining available resources of the network slice is lower than the threshold, and the UE does not have the user capability to use the network slice, the base station may report to the UE The rejection message is sent. In some other embodiments, the core network may also refuse the UE to use the corresponding network slice to conduct a session or access the corresponding network slice for various reasons. At this time, after receiving the instruction from the core network, the base station of the RAN will The corresponding UE is further notified that it cannot be used, so the rejection message is sent to the UE.

Optionally, the sending the reject message of the slice request to the UE includes at least one of the following: if the core network rejects the UE to access the corresponding network slice, send the reject message to the UE; When the number of available resources of the network slice that the UE requests to access is less than a preset threshold, send the rejection message to the UE; when the user capability of the UE does not match the slice capability of the network slice, send the rejection message to the UE The UE sends the rejection message.

Optionally, as shown in Figure 3, the method further includes:

Send slice configuration information of the radio access network to the core network.

In this embodiment, the base station of the RAN will also send its own slice configuration information to the core network, so as to select a basis for the core network to send downlink information to the UE from the network slice.

It should be noted that the sending of the slice configuration information and the aforementioned sending of the slice configuration information may not have a certain sequence, and both may be executed simultaneously or successively.

Optionally, the sending the slice configuration information of the radio access network to the core network includes at least one of the following:

sending the slice configuration information through user-specific signaling;

The slice configuration information is sent through non-user-specific signaling.

The user-specific signaling may be signaling corresponding to a specific UE, and the slice configuration information sent at this time may be the slice configuration information of the specific UE. For example, the user-specific signaling may be: signaling transmitted through a tunnel configured for a specific UE, or signaling sent through a specific link of a specific UE, or specific signaling set for a specific UE.

In some other embodiments, the non-user-specific signaling sends the slice configuration information. The slice configuration information is no longer aimed at a specific UE, but may be aimed at multiple UEs, for example, a group of UEs, or even for one or slice configuration information of multiple cells, one or multiple frequency bands, and one or multiple TAs. In this way, after the core network receives the slice configuration information, it can know the configuration information of the corresponding base station, cell, and TA for the network slice.

Optionally, the slice configuration information sent through non-user-specific signaling includes at least one of the following: a correspondence between network slices and user parameters; a correspondence between network slices and cell lists;

The correspondence between network slices and frequency bands; the correspondence between network slices and tracking areas TA.

The correspondence between the network slice and the user parameters can be used to describe: the correspondence between the user parameters and the network slice that the user authorizes to use or can use, for example, the terminal provided by the user account to use the corresponding network slice terminal needs Capabilities possessed, for example, the terminal capability may be used to describe the communication capability or network capability possessed by the terminal, for example, whether the terminal supports the capability of dual connectivity, etc.

The corresponding relationship between the network slice and the cell list, in this way, you can see the relationship between the available network slice of the site (ie, the base station) and the corresponding cell list. When the core network selects a network slice, not only the core network needs to consider For the corresponding network slice, it is also necessary to consider whether the network slice corresponding to the RAN is sufficient to provide the service for receiving downlink data for the UE.

The corresponding relationship between the network slice and the tracking area TA, such as the TA corresponding to the network slice available to the base station.

Optionally, the slice configuration information sent through user-specific signaling includes at least one of the following:

Information about the network slice available to the UE; for example, the identifier or name of the network slice available to the UE indicates information about the network slice available to the UE.

Constraints on network slices available to the UE. The UE can use the constraints of these network slices, for example, user capabilities and network status information required by the UE to use these network slices.

Optionally, the method further includes: receiving a slice construction request sent by the core network. In some embodiments, the method further includes: sending a rejection message of the slice construction request to the core network.

In some embodiments, if the core network wants to have a session with the UE through a certain network slice, it may need to indicate that there is a corresponding network slice on the RAN side. Therefore, in this embodiment, the base station may ask the core network to build a certain A slice construction request for a network slice. The slice construction request may indicate the type of network slice to be constructed. After receiving the request, the base station may, according to the type and the network resource configuration file corresponding to the network slice type, and Combining with status information of network resources of the current network (the type of network resources, the number of available network resources), etc., it is determined whether the requirements of the core network can be met, so as to establish a corresponding slice construction request. If the base station believes that the network slice is not currently being constructed or that the construction of the corresponding network slice will cause problems such as congestion, the base station may reject the establishment of the network slice, and at this time, may send a rejection message of the slice construction request to the core network , to reject the core network request.

Optionally, the sending a rejection message of the slice construction request to the core network includes:

Sending the rejection message to the core network according to at least one of resource quantity, user parameters and network status.

For example, if the number of network resources in the TA or cell list where the current base station is located is insufficient, the construction of the corresponding network slice can be refused. If it is not satisfied, for example, the signal quality detected at the UE location cannot reach the quality threshold. Even if the network slice is built, but the UE uses the network slice to conduct sessions with poor quality, it can send a rejection message to the core network.

For example, the user parameters may include: terminal capabilities, etc., but are not limited to terminal capabilities.

Optionally, the rejection message further includes: reason information for refusing to construct the network slice.

In some embodiments, the rejection message may only include a rejection instruction. In this embodiment, the rejection message also includes reason information for the rejection, so as to inform the core network of the reason for not building the network slice and reduce subsequent core network requests. The probability of building network slices that cannot be built by base stations or that cannot be used by specific UEs reduces unnecessary signaling overhead.

As shown in FIG. 4A, this embodiment also provides a network slicing application control method, including:

Step S110: Receive slice configuration information distributed by the radio access network RAN.

Optionally, in some embodiments, the method also includes:

Step S130: Send a slice request according to the slice configuration information.

As shown in Figure 4B, in some embodiments, the method may further include:

Step S120: receiving the availability information of the UE's available network slice distributed by the core network;

Step S130 may further be step S131, and step S131 may: send a slice request according to the slice configuration information and the availability information sent by the core network.

The network slicing application control method provided in this embodiment may be a method applied to the UE, and the UE will not only receive the availability information sent by the core network, but the availability information may be the network slice indicated by the core network that the UE can use For example, the core network may determine the network slices available to the user equipment according to the subscription data of the user account run by the user equipment and the subscribed services, so as to form the availability information of the network slices. Of course, there are more than one ways for the core network to determine the availability information of the network slices that the UE can use. A network element of the core network, for example, a mobility management entity (Mobility Management Entity, MME) or an access management function (Access Management Function, AMF), etc. can determine the availability information of a specific UE according to various methods such as preset configurations, and Send to UE through NAS message.

In this way, the UE will obtain information about the availability management of network slices performed by the RAN and the availability management of network slices of the core network, and then combine the two to select the network slice that it needs to access or use, and then send the described slice request.

Optionally, the step S130 may include:

and sending the slice request according to at least one of the slice configuration information, the availability information, and user parameters. The user parameters may include parameters such as user capability, user mobile behavior, user service line, and user slice; the user capability may further include the terminal capability of the UE and the like.

In this embodiment, not only according to the slice configuration information and availability information, but also user parameters such as user capabilities, and only when the three meet the standards, a slice request is sent to the base station to request access or use the corresponding network slice .
