Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present 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 different objects, and are not used for describing a specific order. The terms "comprises," "comprising," and "having," and any variations thereof, of the embodiments of the present application, 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, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The technical solution of the present application will be described in detail with reference to specific examples.

To more clearly illustrate the method for requesting a network slice disclosed in the embodiments of the present application, first, a network slice and an access request procedure of the network slice in the related art are described.

In the related art, in order to meet network requirements in different scenarios, network resources of a common network from an access network to a core network are cut into a plurality of mutually independent network slices for providing different network services according to different network requirements, for example: the intelligent driving network slice is used for independently providing network service for automatic driving; the smart phone network slice is used for providing network service for a mobile phone by a unit and the like. And the electronic equipment can further 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 generally correspond to different Network devices, and different Network devices generally support different Public Land Mobile Networks (PLMNs), wherein each PLMN can be respectively cut into multiple Network slices. For example, PLMN1 may be partitioned into network slice 1, network slice 2; the PLMN2 may be divided into network slice 1 and network slice 2, which is not limited herein.

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

Step 2: first network device 120, upon determining that network slice 2 is not signed up (i.e., electronic device 110 does not have the right to access network slice 2), may send first denial information to electronic device 110 to deny electronic device 110 access to network slice 2.

And 3, step 3: when electronic device 110 roams from a first network (i.e., PLMN1) corresponding to first network device 120 to a second network (i.e., PLMN2) corresponding to second network device 130, electronic device 110 sends a fourth network request to second network device 130, the fourth network request including a request to access network slice 1 and network slice 2.

And 4, step 4: the second network device 130, in case it is determined that the network slice 2 is not signed on according to the fourth network request, will again send second rejection information to the electronic device 110 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 only indicates that the first network device 120 or the second network device 130 rejects the electronic device 110 to access the network slice 2, but does not indicate the reason for the rejection (the reason for the rejection may be that the first network device 120 or the second network device 130 does not support the network slice 2, or the electronic device 110 does not have the right to access the network slice 2). In this regard, when electronic device 110 roams to second network device 130, the request to access network slice 2 is still included in the fourth network request because electronic device 110 does not know the specific reason for being rejected by first network device 120. Therefore, the subsequent second network device 130 feeds back the second rejection information to the electronic device 110, which wastes network air interface resources and increases the time duration for establishing connection between the electronic device and the network device.

Based on this, a 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 illustrating a method for requesting a network slice according to an embodiment of the present application. The method can be applied to electronic devices 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 un-signed state.

In this embodiment, the first network device may be a server, a server cluster, or the like supporting a network. Optionally, the first feedback information may include a cause value of "0011", where the cause value is used to indicate that the corresponding network slice is in an un-signed state (i.e., the electronic device does not have the right to access the corresponding network slice). For example, "network slice 2with 0011" indicates that network slice 2 is in an uncongested state. The reason value of "0011" is compared with the reason value of "0000", which can clearly indicate that the reason why the network slice access request is rejected is that the network slice is in an un-signed state, so that the reason that the first network device does not support the first network slice is eliminated, and when the electronic device subsequently sends a network request to other network devices, the electronic device may not request to access the un-signed first network slice, thereby avoiding wasting air interface resources. In addition, the method only needs to add a new cause value at the network equipment end, and does not need to upgrade the interaction protocol or the network element between the electronic equipment and the network equipment, thereby being simple and convenient to implement and saving the improved cost.

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 have an access right of a certain network slice, the electronic device needs to sign with a corresponding network operator for the network slice. After signing, the electronic device has access to the network slice in the signed state, but does not have access to the network slice in the non-signed state. In this regard, the first network slice being in the non-signed state represents a state in which the electronic device does not have the right to access the first network slice.

In one embodiment, the first network device may send the first feedback information to the electronic device when detecting that the first network slice is in an un-subscribed state. In another embodiment, in the case that the electronic device has a need to access 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; furthermore, when the first network device receives the second network request sent by the electronic device, if it is determined that the first network slice is in the non-signed state, the first network device may send the first feedback information to the electronic device.

By implementing the method, the first network device may feed back the first feedback information to the electronic device only when the electronic device has a need to access the first network slice, so that the first network device is prevented from sending the first feedback information to the electronic device without the need to access the first network slice to notify the electronic device, and further, air interface resources are prevented from being wasted.

204. And storing the first slice identifier corresponding to the first network slice to an un-signed list according to the first feedback information, wherein the un-signed list is used for storing the slice identifier corresponding to the network slice of which the electronic device does not have the access right.

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

Further, if the analysis result indicates that the first network slice is in the no-contract state, the electronic device may store the first slice identifier corresponding to the first network slice to the no-contract list according to the first feedback information. Optionally, 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", without limitation. And further, 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 a Non-Volatile Random Access Memory (NVRAM), a Random Access Memory (RAM), and the like, and is not limited herein. Further, the electronic device may create an unsigned list in the storage medium, where the unsigned list is used to store slice identifiers corresponding to network slices for which the electronic device does not have access rights. For example, if the electronic device does not have the right to access the network slice 2 (i.e., the network slice 2 is in the non-signed state), the electronic device may store the first slice identifier "S-NSSAI 2" corresponding to the network slice 2 in the non-signed list, so that the subsequent electronic device can determine which network slice is in the non-signed state according to the slice identifier stored in the non-signed list.

By implementing the method disclosed in each of the embodiments, the first network device may send, to the electronic device, first feedback information indicating that the first network slice is in an unsigned state, and when receiving the first feedback information, the electronic device may determine that the electronic device does not have an authority to access the first network slice, and then the electronic device may store the first slice identifier corresponding to the first network slice to an unsigned list, and then the subsequent electronic device may not initiate an access request to the network slice without the access authority according to the unsigned list, so that the electronic device may be prevented from requesting the network device to access the unsigned network slice, and network air interface resources are saved; in addition, the electronic equipment can be prevented from requesting the network equipment to access the network slice which is not signed, and the network equipment refuses the interactive 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 method for requesting a network slice according to an embodiment of the present application. The method can be applied to electronic devices 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 unconsignated state.

304. And storing a first slice identifier corresponding to the first network slice to an un-signed list according to the first feedback information, wherein the un-signed list is used for storing a slice identifier corresponding to a network slice which does not have access right of the electronic device.

In an embodiment, after storing the first slice identifier corresponding to the first network slice to the no-subscription list according to the first feedback information, the electronic device may delete the first slice identifier from the no-subscription list after waiting for the first time period. Alternatively, the first time period may be set by the electronic device, the first network device, or a developer, and is not limited herein.

By implementing the method, the electronic device can delete the first slice identifier stored in the un-signed list after waiting for a period of time, so that the first network slice corresponding to the first slice identifier can be prevented from being normally accessed all the time, and the normal access of the subsequent electronic device to the first network slice is ensured.

306. And acquiring a second network slice to be accessed in a second network 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.

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

It is understood that when the electronic device is in different locations or has different network requirements, the electronic device may roam from one network to another to obtain better network services. When an electronic device roams from one network to another, it needs to re-access the network slice under the new network.

Alternatively, 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, the electronic device may determine, according to a current network requirement of the electronic device, a second network slice to be accessed in the first network. Optionally, the current network requirement of the electronic device may be determined according to a scene (including but not limited to an automatic driving scene, a virtual reality scene, a network game scene, and the like) in which the electronic device is currently located.

308. And according to the non-signed list, removing the network slices in the non-signed state in the second network slices 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 obtain an un-signed list from the storage medium, and determine, according to the un-signed list, a fourth network slice in an un-signed state, and then the electronic device may remove the fourth network slice included in the second network slice, so as to obtain a third network slice in a signed state.

For example, the second network slice to be accessed in the second network includes a network slice 1 and a network slice 2, and the first slice identifier stored in the non-signed list corresponds to the network slice 2, the electronic device may remove 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.

When 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 not initiate an access request to a network slice without access right according to the un-signed list, so that the electronic device may be prevented from requesting the network device to access the un-signed network slice, and network air interface resources are saved; in addition, the electronic equipment can be prevented from requesting the network equipment to access the network slice which is not signed, 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 after waiting for a period of time, the electronic device may delete the first slice identifier stored in the un-signed list, so that it may be avoided that the first network slice corresponding to the first slice identifier cannot be normally accessed all the time, and normal access to the first network slice by the subsequent electronic device is ensured.

To more clearly illustrate the method for requesting a network slice disclosed in the embodiment of the present application, the following description is made with reference to fig. 4, where fig. 4 is a timing diagram 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; and 2, step: when determining that the first network slice is in the non-signed 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 non-signed state; and step 3: the electronic device 110 stores the first slice identifier corresponding to the first network slice to the non-signed list according to the first feedback information; and 4, step 4: when the electronic device 110 roams from the first network corresponding to the first network device 120 to the second network corresponding to the second network device 130, the electronic device may obtain a second network slice to be accessed in the second network, remove a network slice in an un-signed state from the second network slice according to the un-signed list to obtain a third network slice in a signed state, and generate a first network request according to the third network slice; and 5: the first network request is sent to the second network device 130.

Referring to fig. 5, fig. 5 is a flowchart illustrating a method for requesting a network slice according to an embodiment of the present application. The method can be applied to electronic devices 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 unconsignated state.

504. And storing the first slice identifier corresponding to the first network slice to an un-signed list according to the first feedback information, wherein the un-signed list is used for storing the slice identifier corresponding to the network slice of which the electronic device does not have the access right.

506. And receiving an identifier set sent by the first network equipment, wherein the network slice corresponding to each second slice identifier included in the identifier set is a network slice in a signed state, and the identifier set is generated by the first network equipment according to the fact that the first network slice is recovered from an un-signed state to a signed state.

In this embodiment, when detecting that subscription information of a network slice changes (for example, switches from an un-subscribed state to a subscribed state, or switches from a subscribed state to an un-subscribed state, or the like), the first network device may send subscription state change information of the network slice to the electronic device through a feedback mechanism, so that the electronic device may adjust a slice identifier in an un-subscribed list according to the subscription state change information (including, but not limited to, deleting the slice identifier or adding the slice identifier). Optionally, the feedback mechanism may include "registration procedure" or "Generic UE configuration update procedure", which is not limited herein.

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

Optionally, the set of identities may include "Allowed NSSAI" or "Configured NSSAI"; wherein "Allowed NSSAI" represents an intersection of a network slice that the electronic device requests access and a network slice that the first network device allows access to by the electronic device; the "Configured NSSAI" indicates a network slice allocated to the electronic device by the first network device, which allows the electronic device to access.

In another embodiment, the first network device includes a first management module and a second management module, the first management module is configured to perform data interaction with the electronic device, and the second management module is at least configured to store a subscription condition between a 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 (AMF); the second Management module may include a Unified Data Management (UDM) module.

In one embodiment, the second management module may generate corresponding state change information, in a case where it is determined that the first network slice is switched from the non-signed state to the signed state, where the state change information is used to indicate that the first network slice is switched from the non-signed state to the signed state; and the second management module may transmit the state change information to the first management device.

Further, the first management device may generate an identification set according to the received state change information, and transmit the identification set to the electronic device. Optionally, the identifier set at least includes a slice identifier corresponding to a first network slice switched from an un-subscribed state to a subscribed state.

Further, in the case 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 un-signed list.

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

Optionally, 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 all slice identifiers in the non-signed list when detecting that the network slice corresponding to the first network device and the signing situation of the electronic device change, so that the subsequent electronic device can not access the network slice corresponding to the slice identifier in the non-signed list all the time, and the electronic device can normally access the network slice subsequently.

508. And if the identification set comprises the first slice identification, deleting the first slice identification from the un-signed 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 un-signed 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 a signed state, so that 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 the electronic device may delete the first slice identifiers from the un-signed list, so as to prevent the first network slices corresponding to the first slice identifiers from being normally accessed all the time, and ensure that the subsequent electronic device normally accesses the first network slices.

By implementing the method, the first network device may feed back the slice identifier corresponding to the signed network slice to the electronic device, so that the electronic device may delete the slice identifier of the network slice restored to the signed state from the un-signed list, thereby preventing the first network slice corresponding to the first slice identifier from being normally accessed all the time, and ensuring the normal access of the subsequent electronic device to the first network slice.

By implementing the method disclosed by each embodiment, the electronic equipment can be prevented from requesting the network equipment to access the network slice which is not signed, and network air interface resources are saved; in addition, the electronic equipment can be prevented from requesting the network equipment to access the network slice which is not signed, 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 device may delete all slice identifiers in the non-signed list when detecting that the network slice corresponding to the first network device and the subscription condition of the electronic device change, so as to prevent the subsequent electronic device from being unable to access the network slice corresponding to the slice identifier in the non-signed list all the time, and ensure that the electronic device can normally access the network slice subsequently; and the first network device may feed back the slice identifier corresponding to the signed network slice to the electronic device, so that the electronic device may delete the slice identifier of the network slice restored to the signed state from the un-signed list, thereby preventing the first network slice corresponding to the first slice identifier from being normally accessed all the time, and ensuring the normal access of the subsequent electronic device to the first network slice.

To more clearly illustrate the method for requesting a network slice disclosed in the embodiment of the present application, the following description is made with reference to fig. 6, where fig. 6 is another timing diagram disclosed in the embodiment of the present application, where: the first network device 120 may include a first management device 140 and a second management device 150;

step 1: the electronic device 110 sends a second network request to the first management device 140, the second network request including at least a request to access the first network slice; and 2, step: when determining that the first network slice is in the non-signed state, the first network device 120 may send, to the electronic device 110, first feedback information through the first management device 140, where the first feedback information is used to indicate that the first network slice is in the non-signed state; and step 3: the electronic device 110 stores the first slice identifier corresponding to the first network slice to the non-signed list according to the first feedback information; and 4, step 4: the second management device 150 may generate corresponding state change information and transmit the state change information to the first management device 140, in a case where it is determined that the first network slice is switched from the non-signed state to the signed state; and 5: the first management device 140 generates an identifier set according to the state change information, and sends the identifier set to the electronic device 110; step 6: the electronic device 110, upon determining that the set of identities includes a first slice identity, deletes the first slice identity from the un-signed list.

Referring to fig. 7, fig. 7 is a flowchart illustrating a method for requesting a network slice according to an embodiment of the present application. The method may be applied to a first network device including, but not limited to, a network-capable server, a cluster of servers, and the like. The method may comprise the steps of:

702. and receiving a second network request sent by the electronic equipment, wherein the second network request at least comprises a request for accessing the first network slice.
