Detailed Description
Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The following describes in detail a network function management method, a device, an electronic apparatus, and a storage medium provided in the embodiments of the present application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
In a 5G core network system architecture, NF (Network Function) associated with SMF includes: AMF: mainly responsible for user mobility management, UDM: the home subscriber server is used for storing subscriber subscription data; UPF: the user data message forwarding method is responsible for forwarding the user data message, and meanwhile, the user data message is counted and used for charging and other functions; PCF: the function of responsible for access and mobility management policies, UE policies, session management policies and charging rules; CHF:5G fuses the key functions of charging. As shown in fig. 1, at a local point in the outfield, when the link N7 between the SMF and the PCF is broken due to network security reinforcement, the following problems occur:
(1) When a user makes a call, AF (Application Function) pushes PCC (Policy and Charging control) rules to the SMF through the PCF, but the N7 port link is disconnected at this time, which results in failure of the user to make a call, affecting normal use of the user basic service.
(2) When the user location information changes, the SMF cannot report the user location information to the PCF, affecting the PCF's switching of the user location-based packages, such as campus packages.
(3) When the user performs 4/5G switching, SMF can not report the RAT and signed QOS information of the user to PCF, which results in limited Internet surfing rate of the user.
Fig. 2 shows a network function management method provided in an embodiment of the present application, where the method is executed by an electronic device and is applied to a first network storage function NRF of a first connection in a dual connection. In other words, the method may be performed by software or hardware installed in the electronic device, the method comprising the steps of:
s201: and receiving a session management function SMF discovery request sent by the target access and mobility management function AMF.
The network storage function (Network Repository Function, NRF) is a new function that provides registration and discovery functions that enable Network Functions (NF) to discover each other and communicate through an API interface. When a user accesses, the AMF will discover the SMF through the NRF.
S202: and sending information of a second SMF to a target AMF in the condition that the first SMF is not available.
The first SMF is an SMF of a first connection in the dual connection, and the second SMF is an SMF of a second connection in the dual connection.
In this embodiment of the present application, the SMF deploys dual links DC1 and DC2 to implement disaster recovery, as shown in fig. 3, where NRF, SMF/packet data network gateway (Packet Data Network Gateway, PGW), binding support function (Bonding Support Function, BSF), PCF, UDM/authentication service function (Authentication Server Function, AUSF), AMF and other network elements are deployed in DC1 and DC2 respectively, BSF in DC1 and BSF in DC2 are connected to the same routing proxy node (Diameter Routing Agent, DRA), AMF in DC1 and AMF in DC2 are connected to the same radio access network (Radio Access Network, RAN), and SMF1 in DC1 and SMF2 in DC2 are connected to the same user plane function (User Plane Function, UPF), so as to implement flexible switching of UPF in two SMFs, and support routing and forwarding of user terminal service data, data and service identification, action and policy execution and the like, while each network element can communicate and discover each other through an API interface.
Specifically, if SMF1 in DC1 is unavailable, SMF1 notifies NRF1 in DC1, and when a user accesses, AMF1 finds that SMF2 in DC2 is available through NRF1, at this time, NRF1 returns SMF2 information to AMF of the target user, so that the user can be guaranteed not to access SMF1 unavailable in DC1, and availability of basic service of the user is guaranteed. Compared with the existing CCFH strategy, the embodiment of the application enables the SMF not to allow the user to access when the peripheral SBI link or NF fails and is not available, and other normal SMFs are used instead, so that normal use of functions such as user communication is ensured, and user experience is enhanced.
According to the network function management method, a session management function SMF discovery request sent by a target access and mobility management function AMF is received; and under the condition that the first SMF is determined to be unavailable, sending information of a second SMF to the target AMF, wherein the first SMF is the SMF of the first connection in the dual connection, and the second SMF is the SMF of the second connection in the dual connection, so that normal use of corresponding service functions of a user can be ensured when a certain service interface of the SMF is unavailable or NF corresponding to a certain service interface is unavailable, and user experience is enhanced.
In one implementation, before the step S102, the method further includes:
and after receiving a link unavailable notification sent by the first SMF, determining that the first SMF is unavailable, wherein the link unavailable notification is used for indicating that the first SMF is disconnected from a plurality of surrounding serviceization interfaces SBI.
In one implementation, before the step S102, the method further includes:
responding to a first Network Function (NF) request message sent by the first SMF, and feeding back a first NF response message to the first SMF, wherein the first NF request message is used for requesting resources related to a first NF, and the first NF response message carries information about whether the first NF is available or not; upon receiving a notification that the first SMF is not available, determining that the first SMF is not available.
In one implementation, before the step S102, the method further includes:
after receiving a link availability notification sent by the first SMF, responding to a first network function NF request message sent by the first SMF, and feeding back a first NF response message to the first SMF, wherein the link availability notification is used for indicating that a plurality of surrounding service interfaces SBI of the first SMF are available, the first NF request message is used for requesting resources related to a first NF, and the first NF response message carries information about whether the first NF is available; upon receiving a notification message that the first SMF is not available, determining that the first SMF is not available.
Specifically, there are two ways in which SMF can detect the availability of peripheral NF:
(1) Service interface (Service Based Interface, SBI) link detection: SMF needs to detect whether an existing link is normal or not, and can consider that the link is not available when the link is totally broken.
(2) NF service detection: the SMF needs to send NF service discovery requests to the NRF, and can consider the service unavailable when there is no NF available in the NRF response.
The SMF can periodically detect the periphery NF through the two detection methods.
When either the SBI link is unavailable or the NF service is unavailable or both, the SMF will set its status to unavailable and notify the NRF of the unavailable status. When a new user accesses, the AMF performs service discovery on the SMF through the NRF, and selects the available SMF to enable the user to access, so that the SMF selected by the user and NF around the SMF are ensured to be available.
When the SMF detects that both the SBI link and the NF service are available when the network fails or the NF fails to recover, the SMF will set its own status to available and notify the NRF.
According to the network function management method provided by the embodiment of the application, after the link unavailable notification sent by the first SMF is received, the first SMF is determined to be unavailable, wherein the link unavailable notification is used for indicating that a plurality of surrounding service interfaces SBI of the first SMF are broken; responding to a first Network Function (NF) request message sent by the first SMF, and feeding back a first NF response message to the first SMF, wherein the first NF request message is used for requesting resources related to a first NF, and the first NF response message carries information about whether the first NF is available or not; determining that the first SMF is not available upon receiving a notification that the first SMF is not available; after receiving a link availability notification sent by the first SMF, responding to a first network function NF request message sent by the first SMF, and feeding back a first NF response message to the first SMF, wherein the link availability notification is used for indicating that a plurality of surrounding service interfaces SBI of the first SMF are available, the first NF request message is used for requesting resources related to a first NF, and the first NF response message carries information about whether the first NF is available; receiving a session management function SMF discovery request sent by a target access and mobility management function AMF; and under the condition that the first SMF is determined to be unavailable, sending information of a second SMF to the target AMF, wherein the first SMF is the SMF of the first connection in the dual connection, and the second SMF is the SMF of the second connection in the dual connection, so that normal use of corresponding service functions of a user can be ensured when a certain service interface of the SMF is unavailable or NF corresponding to a certain service interface is unavailable, and user experience is enhanced.
Fig. 4 illustrates another network function management method provided in an embodiment of the present application, where the method is executed by an electronic device and is applied to a first SMF of a first connection in a dual connection. In other words, the method may be performed by software or hardware installed in the electronic device, the method comprising the steps of:
s402: sending a first notification to a first NRF of a first connection of the dual connection, wherein the first notification comprises: at least one of a link available notification, a link unavailable notification, a first SMF available notification, a first SMF unavailable notification, the link comprising the first SMF plurality of ambient servitization interfaces SBI.
In one implementation, before the step S402, the method further includes:
detecting available states of a plurality of SBIs of the first SMF; transmitting the link unavailable notification in case none of the plurality of SBIs is available; and sending the link availability notification in the case that at least part of the plurality of SBIs are available.
Specifically, SMF periodically detects the perimeter NF by the two detection methods described above. When either the SBI link is unavailable or the NF service is unavailable or both, the SMF will set its status to unavailable and notify the NRF of the unavailable status. When the SMF detects that both the SBI link and the NF service are available when the network fails or the NF fails to recover, the SMF will set its own status to available and notify the NRF. As shown in fig. 3, when SMF1 in DC1 detects that all PCFs are not reachable, it sets its status to unavailable and notifies NRF1.
According to the network function management method, a first notification is sent to a first NRF of a first connection in dual connection, wherein the first notification comprises the following steps: at least one of a link available notification, a link unavailable notification, a first SMF available notification, and a first SMF unavailable notification, wherein the link includes a plurality of peripheral servitization interfaces SBIs of the first SMF, and receives a session management function SMF discovery request sent by a target access and mobility management function AMF through a first NRF of a first connection in a dual connection; and under the condition that the first SMF is determined to be unavailable, sending information of a second SMF to the target AMF, wherein the first SMF is the SMF of the first connection in the dual connection, and the second SMF is the SMF of the second connection in the dual connection, so that normal use of corresponding service functions of a user can be ensured when a certain service interface of the SMF is unavailable or NF corresponding to a certain service interface is unavailable, and user experience is enhanced.
Fig. 5 illustrates another network function management method provided in an embodiment of the present application, where the method is executed by an electronic device and is applied to a first SMF of a first connection in a dual connection. In other words, the method may be performed by software or hardware installed in the electronic device, the method comprising the steps of:
s501: and sending a first NF request message to the first NRF.
The first NF request message is used for requesting resources related to the first NF.
S502: and in response to a first NF response message fed back by the first NRF, sending a notification message that the first SMF is not available to the first NRF if the first NF is not available.
In one implementation, if a first NRF of a first connection in the dual connection receives a notification message that the first SMF is not available, information of a second SMF is sent to a target AMF, where the first SMF is an SMF of the first connection in the dual connection and the second SMF is an SMF of the second connection in the dual connection.
Furthermore, in the network function management method provided by the embodiment of the present application, a first NF request message is sent to a first NRF of a first connection in dual connection through a first SMF of the first connection in dual connection, where the first NF request message is used to request resources related to the first NF; in response to a first NF response message fed back by the first NRF, sending a notification message to the first NRF that the first SMF is not available if the first NF is not available; receiving a session management function SMF discovery request sent by a target access and mobility management function AMF through a first NRF of a first connection in the dual connection; and under the condition that the first SMF is determined to be unavailable, sending information of a second SMF to the target AMF, wherein the first SMF is the SMF of the first connection in the dual connection, and the second SMF is the SMF of the second connection in the dual connection, so that normal use of corresponding service functions of a user can be ensured when a certain service interface of the SMF is unavailable or NF corresponding to a certain service interface is unavailable, and user experience is enhanced.
Specifically, fig. 6 shows a flowchart of a network function management method (taking PCF failure as an example) provided in an embodiment of the present application, where the method includes the following steps:
s601: SMF1 in DC1 detects the link of PCF 1. If the link is normal, step S602 is entered; if the link is abnormal, the flow advances to step S604.
S602: SMF1 sends a request message to NRF1 requesting the discovery of the PCF.
S603: NRF1 returns PCF information. If there is no PCF available, step S604 is performed.
S604: SMF1 sends a request to NRF1 informing NRF1 that the current SMF1 state is unavailable.
S605: the new user accesses.
S606: AMF found SMF by NRF1.
S607: since SMF1 is not available at this time, NRF1 returns information of SMF2 to AMF.
S608: the user accesses through SMF 2.
In this embodiment, only PCF failure is taken as an example to describe the network function management method described in the present application, and the specific network function is not limited, and when other network functions related to SMF fail, for example, UDM, CHF, etc., the steps performed in this embodiment are similar to those described above, so that repetition is avoided and redundant description is omitted.
It should be noted that, the message related to checking the signaling trace includes: after the link between the SMF and PCF is broken, the SMF modifies the state of the SMF to suspend to the NRF through the nnrf. After reestablishing the link between the SMF and PCF, the SMF will modify the state of the SMF to register to the NRF via the nnrf.
