Detailed ways

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus repeated descriptions thereof will be omitted. Some of the block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software, or in one or more hardware modules or integrated circuits, or in different network and/or processor means and/or microcontroller means.

Based on the background technology, it can be seen that there is no implementation scheme for emergency communication of SNPN in the related art.

In order to realize the emergency communication of the SNPN, the access and mobility management function (Access and Mobility Management Function, AMF) in the embodiment of the present disclosure receives the registration request of the user equipment (User Equipment, UE) to register with the SNPN, and then responds to the registration request, A registration acceptance message is sent to the UE, and the registration acceptance message carries the N emergency numbers associated with the SNPN and the attribute of each emergency number in the N emergency numbers, and the attribute of the emergency number is used to indicate the effective area of the emergency number. In this way, after receiving the registration acceptance message, the UE can initiate an emergency communication session request based on the emergency number and the attributes of the emergency number in the registration acceptance message. The SNPN emergency communication method provided by the embodiments of the present disclosure is suitable for SNPN emergency communication services, and does not involve equipment hardware upgrades, does not need to modify any NAS message codes, and only requires relatively simple software upgrades on the AMF side and the UE side. Yes, the transformation of existing network equipment is small and the implementation cost is low.

For ease of understanding, several nouns involved in the present disclosure are firstly explained as follows:

SNPN does not rely on the functions provided by the network operator's public network. A SNPN can be an isolated non-public network (Non-Public Network, NPN) that does not interact with the PLMN, and the NPN and the PLMN can be deployed on different network infrastructures.

SNPN is a private network based on the 5G system architecture, which is completely separated from the public network PLMN. The independence between SNPN and PLMN is mainly reflected in:

(1) SNPN has a unique network identifier, namely NID, which is completely independent of the public network identifier PLMN ID;

(2) SNPN has an independently deployed core network;

(3) SNPN users can only move within the coverage area of SNPN network;

(4) Networking with independent frequency bands.

In related technologies, SPNN mainly has the following three deployment schemes:

Scenario 1: The enterprise fully deploys the 5G system within the scope of the SNPN network, including the radio network (Radio Access Network, RAN) and the core network (Core Network, CN), with dedicated spectrum for SNPN (Figure 1). Since the SNPN core network is independent of the PLMN, SNPN user subscription data, control plane traffic, and user plane traffic all remain within the SNPN network. SNPN network equipment is non-public network equipment, and the use and maintenance of the network are the responsibility of the enterprise deploying the network.

Solution 2: NPN enterprises deploy SNPN by sharing RAN base stations with operators. In this scenario, the SNPN and the PLMN still have different network identities, independent spectrums and independent core networks. The feature of scheme 2 is that the base station of SNPN is shared with PLMN, which means that the wireless access function is provided for SNPN users within the enterprise, and it is the responsibility of the shared base station provided by the mobile network operator (Mobile Network Operator, MNO), thus forming the SNPN subnet .

Solution 3: When an NPN operator deploys an SPN, it not only shares the RAN base station with the operator, but also shares the frequency spectrum with the operator. In this way, SNPN and PLMN have different network identifiers and independent core networks, while the core network of NPN still manages NPN subscribers independently. The feature of scheme 3 is that the base stations and spectrum of SNPN are shared with PLMN, and the shared spectrum is owned by operators.

It should be understood that the technical solutions of the embodiments of the present disclosure may be applied to fifth-generation mobile communication technologies (5th-generation, 5G).

When SNPN is deployed, the geographical location may be within a country, or across several countries, or in areas such as the high seas (not belonging to any country).

Some emergency communication numbers available in SNPN are similar to PLMN emergency numbers (such as 110, 120, etc.), and some may be some emergency communication numbers unique to the private network, which are only valid within the private network.

In view of the fact that there is currently no emergency communication method suitable for SNPN, the inventors found that when UE accesses and registers to a certain SNPN, AMF can send a NAS message to the UE according to the actual geographical deployment characteristics and actual operation requirements of the SNPN. Send a set of emergency communication number sequences applicable to the SNPN, and inform the UE of the attributes of these emergency numbers: whether they are valid in the country or are exclusive numbers belonging to the SNPN. If the UE needs to initiate an emergency communication service, it can clearly know which emergency numbers are only valid in its own country or which emergency numbers are exclusive numbers of the SNPN according to the previously received instructions. In this way, the emergency communication service is realized in the SNPN.

In the following, the application scenarios of the embodiments of the present disclosure are firstly introduced.

Please refer to FIG. 2. FIG. 2 is a schematic diagram of the architecture of the 5G core network in the embodiment of the present application. As shown in the figure, the user equipment UE communicates with the RAN, and the RAN is responsible for the wireless access of the UE. The AMF communicates with the RAN, and the AMF can be used to manage procedures related to UE mobility. The session management entity (Session Management Function, SMF) communicates with the RAN, and the SMF can be used to manage the processes related to the UE session. The user plane functional entity (User Plane Function, UPF) communicates with the RAN, and the UPF is responsible for transmitting data packets, that is, first receiving the data packets sent by the UE through the RAN, and then transmitting the data packets to the data network (Data Network, DN), or from The DN receives the data packet, and then transmits the data packet to the RAN, and the RAN transmits it to the UE.

The 5G core network introduces a Network Slice (NS) structure, and each NS can provide specific services for specific users. If an NS is implemented in network deployment, it is Network Slice Instances (NSI). One NS can implement multiple NSIs. A UE can use multiple NSIs at the same time, and these NSIs can share RAN and AMF, while SMF and UPF are NSI-specific network elements.

NS can be understood as a set of logical network functions that support the communication service requirements of specific usage scenarios or business models. It is the realization of services based on physical infrastructure. These logical network functions can be regarded as evolved from the core packet network (Evolved Packet A series of sub-functions decomposed from the network function under Core, EPC). It can be seen that network slicing is an end-to-end solution, and this end-to-end solution can be applied not only to the core network, but also to the RAN.

NS considers the problem from the perspective of the service layer and the infrastructure layer. The service layer describes the system architecture from a logical level and consists of network functions and the connections between functions. These network functions are usually defined in the form of software packages, which provide templates for defining deployment and operation requirements. The infrastructure layer describes the network elements and resources required to maintain a network slice from the physical level, including computing resources (such as servers in the data center) and network resources (such as aggregation switches, edge routers, cables, etc.).

When the network selects a slice, refer to the requested NSSAI reported by the UE. An NSSAI is a collection of multiple Single Network Slice Selection Assistance Information (S-NSSAI). An S-NSSAI contains slice type, service type and other distinguishing information.

Network slicing essentially divides an operator's physical network into multiple virtual networks. Each virtual network is divided according to different service requirements, such as delay, bandwidth, security, and reliability, so as to flexibly respond to different Network application scenarios.

In 5G systems, UEs need to register with the network to be authorized to receive services, enable mobility tracking and enable reachability.

The use of NSI ID in 5GC is optional and depends on the operator's deployment choice.

During registration, the home network can provide the UE with guidance on roaming information through the AMF. The home network may include an indication that the UE sends an acknowledgment of receipt of the information.

The exemplary implementation manner will be described in detail below in conjunction with the accompanying drawings and embodiments.

First of all, the embodiment of the present disclosure provides an emergency communication method of the independent non-public network SNPN, which can be applied to the SPNN introduced above, as shown in Figure 3, the independent non-public network SNPN The emergency communication method includes steps S302-S308.

In step S302, the UE sends a registration request to register with the SNPN to the network element with the access and mobility management function AMF.

Step S304, the AMF network element receives the registration request from the user equipment UE.

Step S306, in response to the registration request, send a registration acceptance message to the UE, the registration acceptance message includes the N emergency numbers associated with the SNPN and the attributes of each emergency number in the N emergency numbers, and the attribute of the emergency number is used to represent the emergency number effective area.

In step S308, the UE initiates an emergency communication session request based on the emergency number and the attributes of the emergency number in the registration acceptance message.

In the above step S306, after receiving the registration request from the UE, the AMF network element generates a registration acceptance message based on the registration request. The registration acceptance message in the embodiment of the present disclosure also carries the N emergency numbers associated with the SNPN and the attribute of each emergency number in the N emergency numbers, wherein the attribute of the emergency number is used to indicate the effective area of the emergency number.

When the UE needs to perform emergency communication, it can normally initiate an emergency communication session request based on the emergency number and its attributes.

Here, when the UE receives the registration acceptance message from the AMF network element, it may also update the pre-stored emergency number information based on the emergency number and the attributes of the emergency number in the registration acceptance message.

In the above steps S302-S304, the UE first initiates initial registration, that is, the UE sends a registration request to the AMF network element, and the registration request may be a Non-Access Stratum (NAS) message.

The AMF network element receives the registration request, which is sent by the UE.

In some embodiments, the registration request received by the AMF network element may also be forwarded by the RAN. Here, the UE may send the registration request to the RAN, and the RAN selects an AMF network element, and then forwards the registration request to the corresponding AMF network element.

As shown in Figure 4, the UE first sends a registration request message to the RAN.

Here, the registration request message may include access network (Access Network, AN) parameters, registration request content and UE policy container.

The content of the registration request can include registration type, Subscription Concealed Identifier (SUCI) (or 5G-Globally Unique Temporary UE Identity (GUTI) or Permanent Equipment Identifier (PEI)) , Last visited tracking area identity (Tracking Area Identity, TAI), security parameters, requested NSSAI, default configuration NSSAI indication, UE wireless capability update, UE MM core network capability, protocol data unit (Protocol Data Unit, PDU) session state , the list of PDU sessions to be activated, the follow-up request, the Mobile Initiated Connection Only (MICO) mode preference, and the requested Discontinuous Reception (DRX) parameters.

The UE policy container may include a policy section identifier (Policy Section Identifier, PSI) list and an indication that the UE supports an Access Network Discovery & Selection Policy (ANDSP).

The registration type indicates whether the UE wants to perform initial registration or not.

Please continue to refer to Figure 4, the RAN forwards the registration request to the AMF network element.

Here, if the registration request message received by the RAN does not contain 5G-GUTI or the 5G-GUTI does not indicate a valid AMF RAN, the AMF network element is selected based on the (R)AT (Radio Access Type) and the requested NSSAI. If the UE is in the connection management (Connection Management, CM)-CONNECTED state, the RAN may forward the registration request message to the AMF network element.

If the RAN cannot select an appropriate AMF element, it forwards the registration request to the AMF element already configured in the RAN to perform AMF selection.

As shown in Figure 4, after the UE receives the registration acceptance message sent by the AMF, the UE can judge whether the emergency number is valid according to the attributes of the emergency number in the registration acceptance message; when the location of the UE changes, the UE can also check Whether the emergency number received before is valid, and delete the invalid number. Subsequently, the UE initiates an emergency communication session request on the SNPN, and completes the follow-up process according to the normal emergency communication session call process.

In the emergency communication method of the independent non-public network SNPN provided by the embodiments of the present disclosure, the access and mobility management function AMF network element receives the registration request of the UE to register with the SNPN, and then sends a registration acceptance message to the UE in response to the registration request, and then The registration acceptance message carries the N emergency numbers associated with the SNPN and the attribute of each emergency number in the N emergency numbers, and the attribute of the emergency number is used to indicate the effective area of the emergency number. In this way, after receiving the registration acceptance message, the UE can initiate an emergency communication session request based on the emergency number and the attributes of the emergency number in the registration acceptance message. The SNPN emergency communication method provided by the embodiments of the present disclosure is suitable for SNPN emergency communication services, and does not involve equipment hardware upgrades, does not need to modify any NAS message codes, and only requires relatively simple software upgrades on the AMF side and the UE side. Yes, the transformation of existing network equipment is small and the implementation cost is low.

Based on the same inventive concept, the embodiment of the present disclosure provides an emergency communication method of the independent non-public network SNPN, which can be applied to the AMF introduced above, as shown in Figure 5, the independent non-public network The emergency communication method of the public network SPNN includes steps S502-S504.

Step S502, receiving a registration request from the user equipment UE, where the registration request is a request for the UE to register with the SNPN.

Step S504, in response to the registration request, send a registration acceptance message to the UE, so that the UE initiates an emergency communication session request based on the emergency number and the attributes of the emergency number in the registration acceptance message; wherein, the registration acceptance message includes the SNPN associated with the SNPN N emergency numbers and the attribute of each emergency number in the N emergency numbers. The attribute of the emergency number is used to indicate the effective area of the emergency number.

Here, the content of the registration request message is the same as that described in the foregoing embodiments, and will not be repeated here.

In some embodiments, the attribute of the emergency number is valid in the area to which the SNPN belongs, or valid in the SNPN.

In some embodiments, the AMF network element judges the area to which the SNPN belongs, so as to determine in which area the emergency number sent to the UE takes effect. The area to which the SNPN belongs may be within a country. For example, determine which geographic country the SNPN belongs to, and all emergency numbers that need to be issued are similar to public numbers such as 110. In some embodiments, the attribute of the emergency number is indicated by "Extended Local Emergency Numbers List is valid in the country of the NPN from which this IE is received".

In some embodiments, the AMF network element determines the emergency numbers at the granularity of the private network, that is, determines which emergency numbers are exclusive numbers for the private network. In some embodiments, the attribute of the emergency number is indicated by "Extended Local Emergency Numbers List is valid in the NPN from which this IE is received".

In this way, if the UE needs to initiate an emergency communication service, it can clearly know which emergency numbers are only valid in its own country or which emergency numbers are exclusive numbers of the SNPN according to the attributes of the previously received emergency numbers.

In some embodiments, the registration acceptance message further includes network slice selection assistance information NSSAI.

Network slice selection assistance information NSSAI is mainly used for UE registration to SNPN.

The emergency communication method of the independent non-public network SNPN provided by the embodiments of the present disclosure only needs to add related judgment logic functions on the AMF, and corresponding adaptation adjustments on the UE side, which can be realized through software upgrades and are convenient for deployment.

Step S602, sending a registration request for registering to the SNPN to the access and mobility management function AMF network element, so that the AMF sends a registration acceptance message in response to the registration request.

Step S604, initiate an emergency communication session request based on the emergency number and the attributes of the emergency number in the registration acceptance message; wherein, the registration acceptance message includes the N emergency numbers associated with the SNPN and the attributes of each emergency number in the N emergency numbers, The attribute of the emergency number is used to indicate the effective area of the emergency number.

In some embodiments, the above step S604 initiates an emergency communication session request based on the emergency number and the attributes of the emergency number in the registration acceptance message, which may include: obtaining the location information of the UE; determining whether the location information is within the effective area of the emergency number; And in the case that the location information is within the effective area of the emergency number, an emergency communication session request is initiated based on the emergency number.

In the embodiment of the present disclosure, the UE may update the stored emergency number information as its geographical location changes. When the UE is located in the SNPN, the emergency communication service can be established normally; when the UE leaves the area (home country) where the SNPN belongs, the UE can delete the emergency number received before.

In some embodiments, on the basis of the above embodiments, the method may further include: updating the pre-stored emergency numbers based on the N emergency numbers associated with the SNPN and the attributes of each of the N emergency numbers.

When the UE receives the registration acceptance message, it can store the emergency number carried in the registration acceptance message and the attributes corresponding to the emergency number; if the UE has stored the emergency number in advance, the UE can update the stored emergency number based on the received registration acceptance message. The emergency number and the properties corresponding to the emergency number.

It should be noted that here N is a positive integer.

In some embodiments, on the basis of the above embodiments, the method may further include: judging whether the pre-stored emergency numbers are valid based on the attributes of each of the N emergency numbers; and deleting invalid emergency numbers.

In this way, when the UE leaves the area (country) to which the SNPN belongs, the invalid emergency number information can be deleted; or, after the UE location changes, the invalid emergency number information can be deleted based on the attribute information.

In some embodiments, sending a registration request to register with the SNPN to the access and mobility management function AMF network element may include: sending a registration request to the RAN to the radio access network RAN, so that the RAN sends the registration request to AMF network element.

Here, when the UE sends the registration request, it may forward the registration request to the AMF through the RAN.

The embodiment of the present disclosure provides a specific implementation method for emergency communication services applicable to SNPN. AMF adds related judgment logic functions, so that the AMF network element itself can determine which geographical country the SNPN belongs to, and all emergency communication services that need to be delivered. The numbers are all public numbers like 110, or the issued emergency numbers are exclusive to the private network; corresponding adaptation adjustments are added on the UE side, so that the UE can judge whether the existing emergency number group is valid based on its geographical location .
