Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It should be noted that the terms "first," "second," "third," and "fourth," etc. in the description and claims of the present application are used for distinguishing between different objects and not for describing a particular sequential order. The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.

The technical scheme of the application will be described in detail with reference to specific embodiments.

In order to more clearly illustrate a network slice request method disclosed in the embodiments of the present application, first, a network slice and a network slice access request process in the related art are described.

In the related art, in order to meet network requirements in different scenarios, network resources of a public network from an access network to a core network are cut into a plurality of mutually independent network slices for providing different network services for different network requirements, for example: the intelligent driving network slice is used for independently providing network services for automatic driving; the intelligent mobile phone network slice is used for providing network services for mobile phones and the like. And the electronic equipment can initiate an access request to the corresponding network slice according to the network requirement of the electronic equipment.

It should be further noted that different network operators typically correspond to different network devices, and different network devices typically support different public land mobile networks (Public Land Mobile Network, PLMNs), wherein each PLMN may be individually cut into multiple network slices. For example, PLMN1 may be partitioned into network slice 1, network slice 2; the PLMN2 may be divided into a network slice 1 and a network slice 2, which is not limited herein.

Referring to fig. 1, fig. 1 is a schematic diagram of a network slice request flow in the related art according to an embodiment of the present application. Wherein, step 1: the electronic device 110 sends a third network request to the first network device 120, the third network request including a request to access network slice 1 and network slice 2.

Step 2: in the event that the first network device 120 determines that the network slice 2 is not signed up (i.e., the electronic device 110 does not have permission to access the network slice 2), the first rejection information may be sent to the electronic device 110 to reject the electronic device 110 from accessing the network slice 2.

Step 3: when the electronic device 110 roams from a first network (i.e., PLMN 1) corresponding to the first network device 120 to a second network (i.e., PLMN 2) corresponding to the second network device 130, the electronic device 110 sends a fourth network request to the second network device 130, where the fourth network request includes a request to access network slice 1 and network slice 2.

Step 4: in case it is determined from the fourth network request that the network slice 2 is not signed up, the second network device 130 will send the second rejection information to the electronic device 110 again to reject the electronic device 110 to access the network slice 2.

The first reject information and the second reject information generally include a cause value of "0000", which indicates that the first network device 120 or the second network device 130 only rejects the electronic device 110 from accessing the network slice 2, but does not describe the reason for rejection (the reason for rejection may be that the first network device 120 or the second network device 130 does not support the network slice 2, or that the electronic device 110 does not have the authority to access the network slice 2). In this regard, when the electronic device 110 roams to the second network device 130, the fourth network request still includes the request to access network slice 2 because the electronic device 110 does not know the specific reason for rejection by the first network device 120. This results in the subsequent second network device 130 feeding back the second reject information to the electronic device 110 again, which wastes network air interface resources and increases the duration of the connection between the electronic device and the network device.

Based on this, the method for requesting a network slice disclosed in the embodiment of the present application is described below.

Referring to fig. 2, fig. 2 is a flowchart of a network slice request method according to an embodiment of the application. The method can be applied to electronic equipment, including but not limited to mobile phones, tablet computers, smart watches and the like. The method may comprise the steps of:

202. and receiving first feedback information sent by the first network equipment, wherein the first feedback information is used for indicating that the first network slice is in an unsigned state.

In the embodiment of the present application, the first network device may be a server, a server cluster, or the like that supports a network. Optionally, the first feedback information may include a cause value "0011" that is used to indicate that the corresponding network slice is in an unsigned state (i.e., the electronic device does not have permission to access the corresponding network slice). For example, "network slice 2with 0011" indicates that network slice 2 is in an unsigned state. Compared with the reason value of 0000, the reason value of 0011 can clearly indicate that the reason that the network slice access request is refused is that the network slice is in an unsigned state, so that when the reason that the first network device does not support the first network slice is eliminated, and the electronic device subsequently sends the network request to other network devices, the electronic device can not request to access the first network slice which is not signed any more, thereby avoiding wasting air interface resources. In addition, by the method, only a new cause value is needed to be added at the network equipment end, and an interactive protocol or network element between the electronic equipment and the network equipment is not needed to be upgraded, so that the method is simple and convenient to implement, and the improved cost is saved.

Alternatively, the first feedback information may include, but is not limited to, "registration accept (Registration Accept) information", "registration reject (Registration Reject) information", or "configuration update command (Configuration Update Command) information".

It should be further noted that, if the electronic device wants to possess an access right of a certain network slice, the electronic device needs to sign up with a corresponding network operator for the network slice. After signing, the electronic device has access rights to the network slice in the signing state, but does not have access rights to the network slice in the non-signing state. In contrast, the first network slice being in an unsigned state indicates that the electronic device does not have permission to access the first network slice.

In one embodiment, the first network device may send the first feedback information to the electronic device upon detecting that the first network slice is in an unsigned state. In another embodiment, in the event that the electronic device is in need of access to the first network slice, a second network request may be sent to the first network device, the second network request including at least a request to access the first network slice; and further, if the first network device determines that the first network slice is in an unsigned state under the condition that the first network device receives the second network request sent by the electronic device, the first network device may send the first feedback information to the electronic device.

By implementing the method, the first network device can feed back the first feedback information to the electronic device when the electronic device has the requirement of accessing the first network slice, so that the first network device is prevented from sending the first feedback information to the electronic device without the requirement of accessing the first network slice to inform the electronic device, and further waste of air interface resources is avoided.

204. And storing a first slice identifier corresponding to the first network slice to an unsigned list according to the first feedback information, wherein the unsigned list is used for storing slice identifiers corresponding to the network slices of which the electronic equipment does not have access rights.

In the embodiment of the application, when the electronic equipment receives the first feedback information, the electronic equipment can analyze the first feedback information to obtain an analysis result. For example, the electronic device analyzes the first feedback information, and the analysis result includes a cause value of "0011", and the cause value indicates that the corresponding network slice is in an unsigned state, so that the electronic device may determine that the first network slice is in the unsigned state.

Further, if the analysis result indicates that the first network slice is in an unsigned state, the electronic device may store the first slice identifier corresponding to the first network slice to the unsigned list according to the first feedback information. Alternatively, each network slice may correspond to a slice label, for example: network slice 1 may correspond to "S-NSSAI 1" and network slice 2 may correspond to "S-NSSAI 2", which are not limited herein. And the electronic equipment or the network equipment can conveniently identify and manage different network slices.

Optionally, the electronic device may include a storage medium including, but not limited to, non-volatile random access memory (Non-Volatile Random Access Memory, NVRAM), random access memory (random access memory, RAM), and is not limited herein. And the electronic equipment can further create an unsigned list in the storage medium, wherein the unsigned list is used for storing the slice identifications corresponding to the network slices which the electronic equipment does not have access rights. For example, the electronic device does not have the authority to access the network slice 2 (i.e. the network slice 2 is in an unsigned state), the electronic device may store the first slice identifier "S-NSSAI 2" corresponding to the network slice 2 in the unsigned list, so that the subsequent electronic device can determine which network slice is in the unsigned state according to the slice identifier stored in the unsigned list.

By implementing the method disclosed in the embodiments, the first network device may send the first feedback information for indicating that the first network slice is in an unsigned state to the electronic device, when the electronic device receives the first feedback information, it may determine that the electronic device does not have the authority to access the first network slice, and then the electronic device may store the first slice identifier corresponding to the first network slice into the unsigned list, and then the electronic device may not initiate an access request to the network slice having no access authority according to the unsigned list, so as to avoid the electronic device from requesting to access the unsigned network slice to the network device, and save network air interface resources; in addition, the electronic equipment can be prevented from requesting to access the unsigned network slice to the network equipment, and the network equipment refuses the interaction process of the request, so that the time for establishing connection between the electronic equipment and the network equipment can be shortened.

Referring to fig. 3, fig. 3 is a flowchart illustrating another network slice request method according to an embodiment of the present application. The method can be applied to electronic equipment, including but not limited to mobile phones, tablet computers, smart watches and the like. The method may comprise the steps of:

302. And receiving first feedback information sent by the first network equipment, wherein the first feedback information is used for indicating that the first network slice is in an unsigned state.

304. And storing a first slice identifier corresponding to the first network slice to an unsigned list according to the first feedback information, wherein the unsigned list is used for storing slice identifiers corresponding to the network slices of which the electronic equipment does not have access rights.

In one embodiment, after storing the first slice identifier corresponding to the first network slice in the unsigned list according to the first feedback information, the electronic device may delete the first slice identifier from the unsigned list after waiting for the first time period. Alternatively, the first duration may be set by the electronic device, the first network device, or the developer, which is not limited herein.

By implementing the method, the electronic device can delete the first slice identifier stored in the unsigned list after waiting for a period of time, so that the situation that the first network slice corresponding to the first slice identifier cannot be normally accessed all the time can be avoided, and normal access to the first network slice by the subsequent electronic device is ensured.

306. And under the condition that the electronic equipment roams from a first network corresponding to the first network equipment to a second network corresponding to the second network equipment, acquiring a second network slice to be accessed under the second network.

It should be noted that the second network slice to be accessed under the second network is a network slice to be requested to be accessed when the electronic device roams to the second network.

It will be appreciated that the electronic device may roam from one network to another when in a different location or when there are different network demands, to obtain better network services. When the electronic device roams from one network to another, it needs to re-access the network slice under the new network.

Alternatively, in the case that the electronic device roams from a first network corresponding to the first network device to a second network corresponding to the second network device, the electronic device may determine, according to a current network requirement of the electronic device, a second network slice to be accessed under the first network. Alternatively, the current network demand of the electronic device may be determined according to a scene (including, but not limited to, an autopilot scene, a virtual reality scene, a network game scene, etc.) in which the electronic device is currently located.

308. And removing the network slice in the unsigned state in the second network slice according to the unsigned list to obtain a third network slice in the signed state, and generating a first network request according to the third network slice.

Optionally, before sending the network request to the second network device, the electronic device may acquire an unsigned list from the storage medium, and determine a fourth network slice in an unsigned state according to the unsigned list, so that the electronic device may reject the fourth network slice included in the second network slice, to obtain a third network slice in a signed state.

For example, the second network slice to be accessed under the second network includes a network slice 1 and a network slice 2, and the first slice identifier stored in the unsigned list corresponds to the network slice 2, the electronic device may reject the network slice 2 to obtain the network slice 1 in the signed state.

Further, the electronic device may generate a first network request from the third network slice, the first network request including at least a request to access the third network slice.

310. A first network request is sent to a second network device.

Optionally, a data transmission link may be established between the electronic device and the second network device, and the electronic device may send the first network request to the second network device through the data transmission link.

By implementing the method disclosed in each embodiment, when the electronic device roams from the first network corresponding to the first network device to the second network corresponding to the second network device, an access request is not initiated to a network slice without access permission according to the unsigned list, so that the electronic device can be prevented from requesting to access the unsigned network slice to the network device, and network air interface resources are saved; in addition, the electronic equipment can be prevented from requesting to access the unsigned network slice to the network equipment, and the network equipment refuses the interaction process of the request, so that the time for establishing connection between the electronic equipment and the network equipment can be shortened; and the electronic device can delete the first slice identifier stored in the unsigned list after waiting for a period of time, so that the situation that the first network slice corresponding to the first slice identifier cannot be normally accessed all the time can be avoided, and normal access of the subsequent electronic device to the first network slice is ensured.

In order to more clearly describe the network slice request method disclosed in the embodiment of the present application, the following description is presented with reference to fig. 4, and fig. 4 is a timing chart disclosed in the embodiment of the present application, where:

Step 1: the electronic device 110 sends a second network request to the first network device 120, the second network request including at least a request to access the first network slice; step 2: when determining that the first network slice is in the unsigned state, the first network device 120 may send first feedback information to the electronic device 110, where the first feedback information is used to indicate that the first network slice is in the unsigned state; step 3: the electronic device 110 stores a first slice identifier corresponding to the first network slice to the unsigned list according to the first feedback information; step 4: the electronic device 110 may obtain a second network slice to be accessed under the second network when roaming from the first network corresponding to the first network device 120 to the second network corresponding to the second network device 130, reject a network slice in an unsigned state in the second network slice according to an unsigned list to obtain a third network slice in a signed state, and generate a first network request according to the third network slice; step 5: the first network request is sent to the second network device 130.

Referring to fig. 5, fig. 5 is a flowchart of another network slice request method according to an embodiment of the present application. The method can be applied to electronic equipment, including but not limited to mobile phones, tablet computers, smart watches and the like. The method may comprise the steps of:

502. and receiving first feedback information sent by the first network equipment, wherein the first feedback information is used for indicating that the first network slice is in an unsigned state.

504. And storing a first slice identifier corresponding to the first network slice to an unsigned list according to the first feedback information, wherein the unsigned list is used for storing slice identifiers corresponding to the network slices of which the electronic equipment does not have access rights.

506. And receiving an identification set sent by the first network equipment, wherein the network slices corresponding to the second slice identifications included in the identification set are network slices in a signed state, and the identification set is generated by the first network equipment according to the fact that the first network slices are recovered from an unsigned state to the signed state.

In the embodiment of the present application, when the first network device detects that the subscription information of the network slice changes (for example, the first network device switches from an unsigned state to a signed state, or switches from the signed state to an unsigned state, etc.), the first network device may send the subscription state change information of the network slice to the electronic device through a feedback mechanism, so that the electronic device may adjust the slice identifier in the unsigned list according to the subscription state change information (including, but not limited to, deleting the slice identifier or adding the slice identifier). Alternatively, the feedback mechanism may include "registration procedure" or "Generic UE configuration update procedure", without limitation.

In one embodiment, the first network device may generate an identifier set according to one or more second slice identifiers, where each network slice corresponding to the second identifier included in the identifier set is a network slice corresponding to the electronic device and currently in a signed state; the first network device may then send the set of identifications to the electronic device to let the electronic device determine which network slices are in a contracted state.

Alternatively, the identification set may include "Allowed NSSAI" or "Configured NSSAI"; wherein "Allowed NSSAI" represents the intersection of a network slice that the electronic device requests access to and a network slice that the first network device allows the electronic device to access; "Configured NSSAI" represents the network slice that the first network device assigns to the electronic device that allows access to the electronic device.

In another embodiment, the first network device includes a first management module and a second management module, where the first management module is configured to interact data with the electronic device, and the second management module is at least configured to store a subscription condition of the network slice corresponding to the first network device and the electronic device. Optionally, the first management module may include an access and mobility management module (ACCESS AND Mobility Management Function, AMF); the second management module may include a Unified data management module (Unified DATA MANAGEMENT, UDM).

In one embodiment, the second management module may generate corresponding state change information, where the state change information is used to indicate that the first network slice is switched from the unsigned state to the signed state, if the first network slice is determined to be switched from the unsigned state to the signed state; and the second management module can send the state change information to the first management module.

Further, the first management module may generate an identification set according to the received state change information, and send the identification set to the electronic device. Optionally, the identifier set includes at least a slice identifier corresponding to a first network slice that is switched from the contracted state to the contracted state.

Further, under the condition that the electronic device receives the identifier set sent by the first management module, if it is determined that the second slice identifier included in the identifier set includes the first slice identifier, the first slice identifier may be deleted from the subscription list.

In another embodiment, the first network device may send second feedback information to the electronic device when determining that the network slice corresponding to the first network device and the subscription condition of the electronic device change, where the second feedback information is used to indicate that the network slice corresponding to the first network device and the subscription condition of the electronic device change; and the electronic device may delete the first slice identifier included in the unsigned list according to the second feedback information after receiving the second feedback information sent by the first network device.

Alternatively, the second feedback information may include "registration accept (Registration Accept) information" or "configuration update command (Configuration Update Command) information", and the "registration accept (Registration Accept) information" or "configuration update command (Configuration Update Command) information" carries information of subscription information change of the network slice.

By implementing the method, the electronic device can delete the slice identifiers in the unsigned list under the condition that the network slice corresponding to the first network device and the subscription condition of the electronic device are detected to change, so that the situation that the subsequent electronic device cannot access the network slice corresponding to the slice identifier in the unsigned list all the time is avoided, and the subsequent electronic device can access the network slice normally is ensured.

508. If the identification set comprises the first slice identification, deleting the first slice identification from the unsigned list.

Further, after receiving the identifier set sent by the first network device, if it is determined that the second slice identifier included in the identifier set includes the first slice identifier, the electronic device may delete the first slice identifier from the unsigned list.

It can be understood that the network slices corresponding to the second slice identifiers included in the identifier set are all network slices in the signed state, so when the second slice identifiers include the first slice identifiers, it is indicated that the first network slices corresponding to the first slice identifiers have been restored to the signed state, and then the electronic device can delete the first slice identifiers from the unsigned list, so as to avoid that the first network slices corresponding to the first slice identifiers cannot be normally accessed all the time, and ensure normal access to the first network slices by subsequent electronic devices.

By implementing the method, the first network device can feed back the slice identifier corresponding to the signed network slice to the electronic device, so that the electronic device can delete the slice identifier of the network slice restored to the signed state from the unsigned list, and the first network slice corresponding to the first slice identifier can not be normally accessed all the time, so that normal access of the subsequent electronic device to the first network slice is ensured.

By implementing the method disclosed by the embodiments, the electronic equipment can be prevented from requesting to access the unsigned network slice to the network equipment, and network air interface resources are saved; in addition, the electronic equipment can be prevented from requesting to access the unsigned network slice to the network equipment, and the network equipment refuses the interaction process of the request, so that the time for establishing connection between the electronic equipment and the network equipment can be shortened; the electronic equipment can delete the slice identifiers in the unsigned list under the condition that the network slice corresponding to the first network equipment and the subscription condition of the electronic equipment are detected to change, so that the situation that the subsequent electronic equipment cannot access the network slice corresponding to the slice identifier in the unsigned list all the time is avoided, and the subsequent electronic equipment can access the network slice normally is ensured; and the first network device can feed back the slice identifier corresponding to the signed network slice to the electronic device, so that the electronic device can delete the slice identifier of the network slice restored to the signed state from the unsigned list, and the first network slice corresponding to the first slice identifier can not be normally accessed all the time, so that normal access of the subsequent electronic device to the first network slice is ensured.
