Detailed Description

The present application will be described in further detail with reference to the accompanying drawings and examples.

Before describing the embodiments of the present application, 5G-capable capabilities will be explained. The 5G capability refers to at least a 5G Non-Access-Stratum (NAS) procedure capable of supporting a related art rule, for example, a UE (User Equipment) capable of supporting at least a 5G NAS procedure defined by a related art rule is a UE with 5G capability, which may be referred to as a 5G UE; for another example, at least a residential gateway capable of supporting the 5G NAS procedure specified in the related art is a residential gateway with 5G capability, which may be called a 5G residential gateway (english may be expressed as 5G Residential Gateway, abbreviated as 5G-RG).

In order to achieve convergence of a 5G network with other types of networks, the related art proposes the following three network architectures:

architecture 1,3GPP architecture of network and non-3 GPP network convergence;

the architecture 2, a 5G fixed-mobile convergence architecture between a fixed network and a mobile network, can be understood as a wireless and wired convergence architecture;

architecture 3,5G the residential gateway downlink 5G UE accesses the 5G Core Network (english may be denoted as 5G Core Network, abbreviated as 5 GC) through Trusted Non-3GPP gateway function (TNGF, trusted Non-3GPP Gateway Function) or Non-3GPP Network interworking function (N3 IWF, non-3GPP InterWorking Function).

For the architecture 1, the non-3 GPP networks such as Wi-Fi, bluetooth, wire, zigbee, lora, WLAN, HDMI and the like may access the 5G core network based on multiple network elements such as N3IWF, TNGF and the like, for example, the architecture shown in fig. 1 in which the 3GPP network based on N3IWF is integrated with the non-3 GPP network, and the non-trusted (Untrusted) non-3 GPP network (such as public Wi-Fi and the like) may access the 5G core network based on N3 IWF. Based on this architecture, the 5G UE may directly access the 5G core network through a non-3 GPP network, i.e. may be able to use the 5G N1 interface to communicate with the 5G NAS signaling to implement 5G network communication.

With respect to the above architecture 2, by means of the fusion and cooperation between the fixed network and the mobile network, the operation of the whole service and the fusion service can be realized, and various high-quality services such as communication, information, entertainment and the like can be provided for the user, irrespective of the terminal, the network, the application and the location thereof (i.e. the architecture is not limited by these conditions). The 5G fixed shift fusion is specifically realized based on two gateways, one is a resident gateway deployed at the user side and used for solving the fusion problem at the user side; the other is a wired access gateway Function (W-AGF, wireline Access Gateway Function) deployed on the network side, which is used for solving the fusion problem on the network side. The residential gateway is specifically disposed between the UE and the access Network, and may include a 5G residential gateway and a Fixed Network residential gateway (english may be expressed as Fixed Network RESIDENTIAL GATEWAY, abbreviated as FN-RG), where the 5G residential gateway may interface with a 5G radio access Network (english may be expressed as NG Radio Access Network, abbreviated as NG RAN), and may interface with a wired access Network; whereas a fixed network resident gateway can only interface to a wired access network. The W-AGF is specifically deployed between a wired access network and a 5G core network, can form a wired 5G access network (W-5 GAN) together with the wired access network, and can be in butt joint with the 5G core network through 5G N2 and N3 interfaces. The residential gateway and the W-AGF are the basis for realizing 5G fixed-mobile fusion, wherein a 5G fixed-mobile fusion network architecture based on the 5G residential gateway and the W-AGF is shown in figure 2. Based on this architecture, the UE may first access the 5G residential gateway through the non-3 GPP network and then indirectly access the 5G core network through the 5G residential gateway.

For the above architecture 3, considering that the UE under the residential gateway may also have 5G capability, based on the above architecture 2, the UE can only indirectly access the 5G core network through the residential gateway, and cannot use the 5G N1 interface to implement 5G network communication with the 5G NAS signaling. Therefore, the architecture 1 and the architecture 2 can be fused to obtain an architecture 3, that is, a fused architecture combining a 3GPP network and a non-3GPP network, the 5G fixed-mobile fused architecture is integrally regarded as a 'non-trusted non-3GPP access' or a 'trusted non-3GPP access', and the 5G core network is accessed through N3IWF or TNGF; the network architecture of the 5G UE connected to the 5G core network through TNGF in the 5G residential gateway is shown in fig. 3. Based on this architecture, the 5G UE downlinked with the residential gateway can directly access the 5G core network based on the connection with the residential gateway, i.e. can use the 5G N1 interface to realize 5G network communication with the 5GNAS signaling, and can transparently transmit the N1 interface NAS signaling and PDU session traffic between the 5G UE and the 5G core network in a Trusted Non-3GPP access network (TNAN, trusted Non-3GPP Access Network).

In the related art, the NEF may support convergence and outturn of 5G network capabilities. As shown in fig. 4, the NEF southbound interfaces with other 5G core network elements and northbound provides a capability Application Program Interface (API) for AF calls through the N33/Nnef interface. Based on this architecture, the NEF can have at least the following four 5G network capabilities:

Monitoring capabilities, i.e. the NEF may monitor a UE's specified events and generate event notifications to send to a third party AF, which may be used to open mobility management of the UE, such as UE location, reachability, connection loss events, etc.;

the preconfiguration capability, namely, the third party AF can provide some information for the 5G system through the NEF, such as the expected route of the UE, the requirement of the UE on the network and the like, so that the system can be optimized in a targeted manner;

policy/charging capability, i.e. the third party AF can issue charging policies, quality of service (QoS) policies, etc. for the 5G system through the NEF;

The analysis reporting capability, i.e. the third party AF can obtain the network analysis report through the NEF.

In addition to the four service capabilities described above, as technologies such as network slicing, edge computing, big data, artificial Intelligence (AI) are applied and developed in 5G networks, the 5G networks can abstract more capabilities to provide to business application layers, such as network slicing services, edge computing services, location services, 5G voice and message services, data analysis services, etc.

As can be seen from the above description, in the related art, for an area where a 5G signal is not covered or the signal quality is poor, such as some residential cells, hospitals in remote areas, factories, etc., which exist in a real production and life scenario, a 5G UE can access a 5G network based on the above architecture 2, but under the architecture, the UE indirectly accesses the 5G network through a 5G residential gateway, and does not support a 5G N1 interface and 5GNAS signaling between the UE and a 5G core network, so that the UE cannot conveniently use advanced technologies of 5G, such as network slicing, UE routing policies (urs, UEs Route Selection Policy), etc. The above architecture 3 can solve the problem that the UE can access the non-3 GPP network first, and then access the 5G core network through the N3IWF or TNGF, so as to realize direct communication with the 5G network. For the area with good 5G coverage, the UE can access the 5G core network through the 5G wireless access network and simultaneously access the 5G core network through the non-3 GPP network based on the framework 3, so that dual-path transmission is realized, and further, certain high-reliability application scenes, such as a hospital remote operation scene, and the like, are satisfied. In other words, a 5G UE (i.e., a 5G capable UE) downlinked by a 5G residential gateway may access a 5G network in two ways:

Based on the architecture 2, the 5G core network is indirectly accessed through the 5G resident gateway, and the uplink and downlink messages of the 5G UE are subjected to protocol conversion and forwarding of the 5G resident gateway; in this way, the 5G network can only directly perceive the 5G residential gateway, but cannot perceive the 5G UE;

Based on the architecture 3, the 5G core network is directly accessed, the 5G UE and the 5G network can directly interact with the 5G NAS signaling through a 5G N1 interface, and the 5G resident gateway transparently transmits the NAS signaling between the UE and the 5G core network; in this manner, the 5G network may perceive a 5G UE, but may not perceive that the UE is a UE that is downlinked to the 5G residential gateway, i.e., may not perceive the 5G residential gateway connected to the UE.

As can be seen from the above description, no matter the 5G UE accesses the 5G network in the first mode or the second mode, the 5G network cannot sense the 5G UE connected down with the 5G residential gateway, that is, cannot sense the association relationship between the 5G residential gateway and the 5G UE, which may cause the following two problems:

Problem 1, for the 5G UE in the first mode, when the place where the UE is located has 5G signal coverage, the UE may directly access the 5G network through the 5G base station, so if the 5G network senses that the UE is a UE connected down to the 5G residential gateway, the UE may actively issue N3IWF selection information (such as an Internet Protocol (IP) address of the N3IWF, a fully defined domain name (FQDN), etc.) to the UE, so that the UE may select a corresponding N3IWF, and directly access the 5G network in the second mode, thereby implementing characteristics such as 5G multipath transmission. However, the above functional requirements cannot be achieved because the existing 5G network cannot sense the association relationship between the 5G residential gateway and the 5G UE.

Problem 2, for the 5G network in the first mode, the UE and the 5G residential gateway are two independent UEs, but in reality, all data packets of the UE need to be forwarded through the 5G residential gateway, that is, the UE can realize normal 5G communication if the 5G residential gateway supports and establishes the required data channel. For example, when a UE needs to access a network slice, the 5G residential gateway needs to support and access the network slice, or the network slice accessed by the 5G residential gateway can map or support the network slice required by the UE (e.g., the quality level of Service Level Agreement (SLA) of the network slice currently accessed by the 5G residential gateway is higher than that of the network slice required by the UE, etc.). Therefore, the 5G network needs to cooperate with the policies and flows related to access management, session management, user plane management, etc. of the UE and the 5G residential gateway, so as to ensure that the 5G residential gateway can normally support the service requirements of the UE. However, the above functional requirements cannot be achieved because the existing 5G network cannot sense the association relationship between the 5G residential gateway and the 5G UE.

In summary, in the related art, the network side may not meet the service requirement of the terminal because the network side cannot perceive the association relationship between the terminal and the residential gateway.

Based on this, in various embodiments of the present application, the network function obtains and stores the association relationship between the terminal and the residential gateway, and may perform related operations based on the association relationship, so as to implement perception of the network side on the terminal associated with the residential gateway, that is, implement perception of the network side on the association relationship between the terminal and the residential gateway, so that the network side can implement collaboration between the residential gateway and the terminal based on the association relationship between the terminal and the residential gateway, and further better satisfy service requirements of the terminal, such as meeting functional requirements corresponding to the above-mentioned problem 1 and problem 2.

In addition, in various embodiments of the present application, since the network side can perceive the associated terminal under the residential gateway, the management and control capability of the network side to the accessed terminal is enhanced, that is, the manageability and controllability of the network side to the accessed terminal are ensured, thereby improving the security of the network and further improving the service quality of the network and the residential gateway.

An embodiment of the present application provides an information transmission method, applied to a first function, as shown in fig. 5, the method includes:

step 501: acquiring first information, and storing the first information, wherein the first information characterizes the association relationship between a terminal and a resident gateway;

Step 502: performing a related operation based on the first information, i.e. performing at least one of step 503, step 504, step 505;

Step 503: sending the association relation between the terminal and the resident gateway to a second function;

Step 504: acquiring an association event between a terminal and a resident gateway, wherein the association event is associated with the change of the association relationship between the terminal and the resident gateway; in other words, the association event is associated with a change of association relationship, and the association relationship comprises the association relationship between the terminal and the resident gateway;

Step 505: and sending an association event between the terminal and the resident gateway to a second function, wherein the association event is associated with the change of the association relationship, and the association relationship comprises the association relationship between the terminal and the resident gateway.

In practical application, the terminal may also be referred to as UE, and may also be referred to as a user.

In practical application, the terminal may include a 5G terminal, i.e. a terminal with 5G capability; the residential gateway may comprise a 5G residential gateway, i.e. a 5G capable residential gateway.

In practical application, the terminal and the residential gateway can establish connection of other types of networks besides the 5G network, such as connection of Wi-Fi, bluetooth, wire, zigbee, lora, WLAN, HDMI and other non-3 GPP networks. The terminal can access the 5G core network in the first mode and/or the second mode based on the connection established with the resident gateway; meanwhile, the terminal can also directly access the 5G core network through the wireless access network to realize dual-path transmission, for example, the terminal is directly connected to the 5G core network through a 5G base station. The residential gateway may be connected to the 5G network via a wired network or may be connected to the 5G network via a wireless means. The specific connection manner between the terminal and the residential gateway and the specific manner in which the terminal and/or the residential gateway access the 5G network may be determined according to requirements, which is not limited by the embodiment of the present application.

When the method is actually applied, after the terminal and the resident gateway are connected, the identification of the opposite terminal can be obtained through the modes of access network query protocol (ANQP, access Network Query Protocol) query, information interaction and the like, so that the association relationship between the terminals can be determined; in other words, the first information may be generated (i.e. determined) by the terminal and reported to the network side, or may be determined by the residential gateway and reported to the network side, and the first information may include the second identifier of the terminal and the third identifier of the residential gateway. The specific implementation manner of the second identifier may be determined according to requirements, for example, a mobile station international integrated services digital network number (MSISDN, mobile Station international ISDN number), an international mobile subscriber identity (IMSI, international Mobile Subscriber Identity), a subscriber permanent identifier (SUPI, SUbscription PERMANENT IDENTIFIER), a subscriber hidden identifier (SUCI, SUbscription Concealed Identifier), an IP address, a media access Control (MAC, media Access Control) address, a permanent device identifier (PEI, PERMANENT EQUIPMENT IDENTIFIER), etc., so long as the function of the second identifier is implemented. Correspondingly, the third identifier is used for identifying the identity of the residential gateway, and the specific implementation manner of the third identifier can also be determined according to requirements, such as MSISDN, IMSI, SUPI, SUCI, IP addresses, MAC addresses, PEI and the like, and the embodiment of the present application is not limited, so long as the function of the third identifier is implemented.

Based on this, in combination with different manners of generating the first information (i.e. determining the first information by the terminal or the residential gateway) and different manners of accessing the terminal and/or the residential gateway to the 5G network, the specific implementation of step 501 may at least include the following three implementations, which respectively correspond to three different reporting channels of the first information:

in the mode 1, the resident gateway determines the first information and reports the first information to a first platform for managing a terminal and/or the resident gateway, and an AF (AF) arranged on the first platform sends the first information to the first function through a NEF (network element function);

mode 2, the residential gateway determines the first information, and sends the first information to an AMF through a wired network, where the AMF sends the first information to the first function;

In mode 3, the terminal determines the first information, and sends the first information to an AMF through a radio access network, where the AMF sends the first information to the first function.

As can be seen from the above description, the first function may acquire the first information from the residential gateway or terminal through other network functions (denoted as third function in the following description).

Based on this, in an embodiment, the acquiring the first information may include:

and receiving the first information sent by the third function.

The third function may include AF provided on a first platform, where the first platform is used to manage a terminal and/or a residential gateway; or the third function may comprise an AMF. In the case where the third function includes the AF, the receiving the first information sent by the third function may include: and receiving the first information sent by the AF through the NEF. In the case where the third function includes the AMF, the receiving the first information sent by the third function may include: and receiving the first information sent by the AMF.

In practical application, the first platform may also be called a unified management platform, etc., and the name of the first platform is not limited in the embodiment of the present application, so long as the function of the first platform is implemented. In addition, it may be understood that the management of the terminal and/or the residential gateway by the first platform may include, but is not limited to, access management, registration management, configuration management, application management, etc., and the specific deployment manner of the first platform may include a cloud, a public server, etc., and the specific function and the specific deployment manner of the first platform are not limited in the embodiment of the present application.

For the above mode 1, in practical application, after the terminal establishes a connection with a residential gateway, eleventh information for registration may be sent to the residential gateway, where the eleventh information may at least include twelfth information and/or a second identifier of the terminal, and the twelfth information indicates that the terminal has 5G capability; after receiving the eleventh information, the residential gateway may determine the first information based on the eleventh information, and report the first information to the first platform; the AF on the first platform can send the first information to the NEF by calling an API of the NEF; the NEF can send the first information to the first function after authentication of the identity and the authority of the first platform is completed.

The eleventh information may be referred to as registration information, the twelfth information may be referred to as 5G capability indication, etc., and the names of the eleventh information and the twelfth information are not limited in the embodiments of the present application, as long as the functions thereof are implemented. In addition, the specific implementation manner of the twelfth information may also be determined according to the requirement, such as bits (bits), boolean values (boolean), character strings, etc., which is not limited in this embodiment of the present application. Illustratively, a bit type value of "1", a bootan type value of "true", and a string type value of "5Gcapable" may represent (i.e., represent) the terminal as being 5G capable.

For the above mode 2, in practical application, after the terminal establishes a connection with a residential gateway, the eleventh information for registration may be sent to the residential gateway; upon receiving the eleventh information, the residential gateway may determine the first information based on the eleventh information, send NAS signaling containing the first information to the AMF through an N1 interface (intermediate forwarding via the W-AGF) (i.e., send the first information to the AMF through a wired network), and send the first information to the first function by the AMF.

For the above mode 3, in practical application, after the terminal establishes a connection with the residential gateway, the third identifier of the residential gateway may be obtained by using an ANQP query method, the first information is determined based on the third identifier and the second identifier thereof, NAS signaling containing the first information is sent to the AMF through an N1 interface (intermediate forwarding via a base station) (i.e., the first information is sent to the AMF through a radio access network), and the AMF sends the first information to the first function.

In practical application, for the above modes 2 and 3, considering that the 5G core network can perceive the identity of the terminal/residential gateway through communication with the terminal/residential gateway, in order to reduce the number of signaling and save communication resources, the first information sent by the terminal/residential gateway to the AMF may not carry the identity of the terminal and only carry the identity of the associated residential gateway/terminal, and may indicate in the first information that the current information can characterize the association relationship between the terminal and the residential gateway, so that after receiving the first information, the AMF may automatically generate the association relationship between the terminal and the residential gateway.

Based on this, in an embodiment, the first information may include a second identifier of the terminal or a third identifier of the residential gateway, and the first information may further include third information, where the third information indicates that a type (which may be understood as a cell type) of the first information is information characterizing an association relationship between the terminal and the residential gateway, and/or indicates that the terminal is 5G capable.

Wherein the third information indicates that the type of the first information is information representing the association relationship between the terminal and the residential gateway, which can be understood that the third information indicates that the first information can represent the association relationship between the terminal and the residential gateway; in other words, the third information indicates the type of the first information, which is: information capable of characterizing an association between the terminal and a residential gateway.

In practical application, for the above mode 2, the first information sent by the residential gateway to the AMF may only include the second identifier of the terminal and the third information, and need not include the third identifier of the residential gateway. For the above mode 3, the first information sent by the terminal to the AMF may include only the third identifier of the residential gateway and the third information, and need not include the second identifier of the terminal. In this way, on the one hand, based on the third information, the 5G core network can learn that the terminal has the 5G capability, so that the twelfth information does not need to be repeatedly reported, that is, the first information does not need to include the twelfth information; on the other hand, the terminal/resident gateway sends the first information to the 5G core network through NAS signaling, so the 5G core network can sense the identification of the terminal/resident gateway, and therefore the identification of the terminal/resident gateway does not need to be repeatedly reported, namely the first information does not need to contain the identification of the terminal/resident gateway; therefore, the number of signaling can be effectively reduced, and communication resources are saved.

In practical application, the third information may also be referred to as a cell type indication, etc., and the name of the third information is not limited in the embodiment of the present application, so long as the function is implemented. In addition, the specific implementation manner of the third information may also be determined according to requirements, such as a bitmap (bitmap), a number, etc., which is not limited in the embodiment of the present application. For example, when the third information is implemented by using a bitmap mode, it is assumed that a bitmap of 4 bits is used, and a bit1 type value of "1" may indicate that the type of the first information is "association relationship between the 5G terminal and the residential gateway"; when the third information is implemented in a numbering manner, it is assumed that a 4-bit number is adopted, and "0010" may represent that the type of the first information is "association relationship between the 5G terminal and the residential gateway".

In practical application, the first function may include a network function such as universal data management (UDM, universal DATA MANAGEMENT), and a specific type of the first function may be determined according to requirements, which is not limited in the embodiment of the present application, so long as the function is implemented. In case the first function comprises a UDM, the UDM may save the first information into a unified data warehouse function (UDR, unified Data Repository).

In an embodiment, the method may further comprise:

a first identification (such as an ID) of an association between the terminal and the residential gateway;

And the association state between the terminal and the resident gateway.

The first identifier may be used as a unique identifier of the corresponding association relationship in the system. In addition, the specific implementation manner of the first identifier may be determined according to requirements, such as a number, a character string, and the like, which is not limited in the embodiment of the present application.

The association state between the terminal and the residential gateway may reflect the current connection situation (i.e., the current connection state) between the terminal and the residential gateway, where the association state may include, but is not limited to, a connection state (may also be referred to as a normal state), a disconnection state, and the like, and the embodiment of the present application is not limited thereto. In addition, the specific implementation manner of the association state may also be determined according to requirements, such as bit, number, character string, bootan, etc., which is not limited in the embodiment of the present application. Illustratively, when the association state is implemented in a bit manner, a bit type value of "0" may represent a normal state, and a bit type value of not "1" may represent an off state; when the association state is realized by adopting a character string mode, the character string of "connect" can represent a normal state, and the character string of "disconnect" can represent a disconnection state.

In practical application, the specific form of the first information, the corresponding first identifier and the associated state stored by the first function may also be determined according to requirements, which is not limited by the embodiment of the present application. For example, when the first function includes a UDM, after the UDM obtains the first information, the first identifier may be generated for the association relationship and the corresponding association state may be determined to be "normal", and then the first identifier, the second identifier, and the third identifier may be stored in the UDR as an association relationship record.

In practical application, the first function needs to maintain the first information so as to ensure the instantaneity and accuracy of the association relationship between the terminal and the resident gateway; in other words, the first function needs to update the corresponding association relationship in time when the association state between the terminal and the residential gateway changes. Thus, the first function needs to acquire an association event between the terminal and the residential gateway. Here, it can be understood that the association event is associated with a change in association relationship between the terminal and the residential gateway, that is, the association event is associated with a change in association state between the terminal and the residential gateway; in other words, the association event may include an event that characterizes a change in association state between the terminal and a residential gateway.

In practical application, the resident gateway can detect the association event by using a heartbeat mechanism between the resident gateway and the terminal, and report the association event to the first function through the third function. Here, in the process of reporting the association event by the residential gateway, in order to save resources, the first identifier may be used to characterize the corresponding association relationship, so after the first function stores the first information, the storage result of the first information (i.e. whether the first information is successfully stored) and the first identifier may be sent to the residential gateway through the third function.

Based on this, in an embodiment, the method may further include:

A storage result of the first information;

In practical application, after receiving the second information, the third function may forward the second information to the residential gateway. Wherein, in case the third function comprises an AF provided on the first platform, the first function may send the second information to the AF through a NEF, and the AF may forward the second information to the residential gateway through the first platform. In the case where the third function includes an AMF, after the AMF receives the second information, the AMF may forward the second information to the residential gateway through a wired network.

In practical application, after receiving the second information, the resident gateway may start a heartbeat mechanism with the terminal to detect the association event. Or when the third function forwards the second information to the residential gateway, tenth information can be sent to the residential gateway, and the tenth information indicates the residential gateway to start a heartbeat mechanism with the terminal; in other words, after the residential gateway receives the tenth information, a heartbeat mechanism with the terminal may be initiated to detect the association event. The tenth information may also be referred to as a heartbeat mechanism start instruction, etc., and the name of the tenth information is not limited in the embodiments of the present application. So long as its function is achieved. In addition, the specific implementation manner of the tenth information may also be determined according to requirements, such as bit, number, character string, etc., which is not limited in the embodiment of the present application. Illustratively, a bit type value of "0", a string "heartbeat" may represent the initiation of a heartbeat mechanism, i.e. a heartbeat mechanism between the residential gateway and the terminal is instructed to be initiated.

In practical applications, the specific configuration manner of the configuration information related to the heartbeat mechanism (which may be understood as the configuration information for starting the heartbeat mechanism between the residential gateway and the terminal, and referred to as ninth information in the following description) may be determined according to requirements, which is not limited in the embodiments of the present application. For example, the ninth information may be preset on the residential gateway, and after the residential gateway receives the second information and/or tenth information sent by the third function, the ninth information may be sent to the terminal, so as to start the heartbeat mechanism. Or the ninth information may be preset on the third function, after the third function receives the second information, the second information and the ninth information may be sent to the residential gateway together, and after the residential gateway receives the second information and the ninth information, the residential gateway may send the ninth information to the terminal, so as to start the heartbeat mechanism. Or in the case that the third function includes AF provided on the first platform, the ninth information may be preset on the first platform, in a process that the AF forwards the second information to the residential gateway through the first platform, the first platform may send the second information and the ninth information to the residential gateway together, and after the residential gateway receives the second information and the ninth information, the residential gateway may send the ninth information to the terminal, so as to start the heartbeat mechanism.

In an embodiment, the ninth information may include at least one of:

The first duration may also be referred to as a heartbeat interval duration, etc., and the name of the first duration is not limited in the embodiment of the present application, so long as the function thereof is implemented. In addition, the specific implementation manner of the first duration may also be determined according to requirements, such as numbers, character strings, and the like, which is not limited in the embodiment of the present application. For example, when the first duration is implemented digitally, a digital type value of "1" may represent 1 second, that is, a time interval for sending a heartbeat message between the residential gateway and the terminal is 1 second; when the first duration is implemented in a string manner, the string type value "1s" may represent 1 second.

The second duration may also be referred to as a heartbeat timeout timer duration, etc., and the name of the second duration is not limited in the embodiment of the present application, so long as the function thereof is implemented. It can be appreciated that in the case where the duration of the continuous loss of the heartbeat message sent between the residential gateway and the terminal exceeds the second duration, it can be determined that the association is broken; in other words, it may be determined that the first event occurs, i.e. the association state between the terminal and the residential gateway is changed from the connected state to the disconnected state. In addition, the specific implementation manner of the second duration may also be determined according to requirements, such as numbers, character strings, and the like, which is not limited in the embodiment of the present application. Illustratively, when the second duration is implemented digitally, a digital type value of "10" may represent 10 seconds; when the second duration is implemented in a string manner, the string type value of "10s" may represent 10 seconds.

The third duration may also be referred to as an association relationship suspension timer duration, etc., and the name of the third duration is not limited in the embodiment of the present application, so long as the function thereof is implemented. It may be appreciated that the third time period is longer than the second time period, and in a case where a duration of a heartbeat message sent between the residential gateway and the terminal continuously lost exceeds the third time period, it may be determined that the association is suspended, that is, it may be determined that the second event occurs. Here, the association state between the terminal and the residential gateway is suspended, which can be understood that the association relationship between the terminal and the residential gateway no longer exists. In addition, the specific implementation manner of the third duration may also be determined according to requirements, such as numbers, character strings, and the like, which is not limited in the embodiment of the present application. Illustratively, when the third duration is implemented digitally, a digital type value of "100" may represent 100 seconds; when the third duration is implemented in a string manner, the string type value "1h" may represent 1 hour.

In practical application, when the duration of the heartbeat message continuously lost between the residential gateway and the terminal exceeds the second duration but does not reach the third duration, the association recovery can be determined, that is, the association state between the terminal and the residential gateway is changed from the disconnection state to the connection state, and at this time, the occurrence of the third event can be determined.

As can be seen from the above description, the association event between the terminal and the residential gateway may comprise at least one of:

a second event, wherein the second event characterizes that the association state between the terminal and the resident gateway is stopped, namely, the association relationship between the terminal and the resident gateway is not existed any more;

And a third event characterizing that the association state between the terminal and the residential gateway is changed from a disconnected state to (i.e., restored to) a connected state.

In actual application, the first event may also be called an association disconnection event, the second event may also be called an association suspension event, and the third event may also be called an association restoration event.

In actual application, when the resident gateway detects the association event by using a heartbeat mechanism between the resident gateway and the terminal, eighth information can be sent to the third function, wherein the eighth information comprises the association event detected by the resident gateway; after receiving the eighth information, the third function may forward the eighth information to the first function, so that the first function obtains the association event.

Based on this, in an embodiment, the specific implementation of step 504 may include:

Wherein, the acquiring the eighth information may include:

And receiving the eighth information sent by the third function.

In actual application, in the case that the third function includes AF provided on the first platform, the residential gateway may send the eighth information to the first platform, where the AF on the first platform may send the eighth information to the NEF by calling an API of the NEF, and then the NEF sends the eighth information to the first function; in other words, the first function may receive the eighth information transmitted by the AF through the NEF. In the case where the third function comprises an AMF, the residential gateway may send NAS signaling containing the eighth information to the AMF via an N1 interface (intermediate forwarding via a W-AGF) (i.e., send the eighth information to the AMF via a wired network), the eighth information being sent by the AMF to the first function; in other words, the first function may receive the eighth information transmitted by the AMF.

In an embodiment, the eighth information may further include:

and a fourth identification of the association event.

Wherein the fourth identifier may be used as a unique identifier of the associated event in the system, and may characterize the type of the associated event, i.e. the associated event is the first event, the second event or the third event. In addition, the specific implementation manner of the fourth identifier may be determined according to requirements, such as a number, a character string, a bootan, and the like, which is not limited by the embodiment of the present application. For example, when the fourth identifier is implemented in a numbering manner, a value of "0" of the numbering type may indicate that the association is broken (i.e., the first event), a value of "1" of the numbering type may indicate that the association is restored (i.e., the third event), and a value of "2" of the numbering type may indicate that the association is aborted (i.e., the second event); when the fourth identifier is implemented in a string mode, a string type value of "disconnect" may indicate that the association is broken, a string type value of "resume" may indicate that the association is restored, and a string type value of "delete" may indicate that the association is suspended.

In practical application, after the first function receives the eighth information, the association relationship between the stored terminal and the resident gateway can be updated. In the case of the occurrence of the first event, the first function may update the association state of the corresponding association relationship from a connection state to a disconnection state; in the case of occurrence of the second event, the first function may delete the corresponding association relationship; in the case where the third event occurs, the first function may update the association state of the corresponding association relationship from the disconnection state to the connection state.

In practical applications, the second function may include a network function that may need to perform cooperation between the residential gateway and the terminal, for example, an AMF, a session management function (SMF, session Management Function), and a network function that cooperate with each other in terms of policies and flows related to access management, session management, user plane management, and the like, where the specific type of the second function may be determined according to the requirement, which is not limited in the embodiment of the present application, so long as the function is implemented.

In actual application, the first function can actively provide the association relationship between the terminal and the resident gateway for the second function; or the second function may retrieve the association between the terminal and the residential gateway from the first function as needed.

Based on this, in an embodiment, the specific implementation of step 503 may include:

and sending fifth information to the second function based on the fourth information, wherein the fifth information comprises the association relation between the terminal corresponding to the search condition and the resident gateway.

In practical application, the search condition may include at least one of:

a second identifier of the terminal;

a third identity of the residential gateway;

And (5) associating the states.

In practical application, in the case that the first function includes a UDM, the UDM may query, from the UDR, an association record that meets the search condition. For example, with the second identifier as a search condition, there may be only one or a small number of records; taking the third identifier as a retrieval condition, possibly inquiring a plurality of association records; wherein, the field of each record may include, but is not limited to, the first identifier, the second identifier, the third identifier and the association status, and the fifth information may include an association record satisfying the search condition.

In actual application, the first function can actively provide the second function with an association event between the terminal and the resident gateway; or the second function may subscribe to the first function for association events of a specific association relationship as needed.

Based on this, in an embodiment, the specific implementation of step 505 may include:

And sending seventh information to the second function based on the sixth information, wherein the seventh information comprises an association event between the terminal subscribed by the second function and a resident gateway.

In practical applications, the sixth information may include at least one of:

a fourth identification of an associated event;

an address for receiving the seventh information;

and a first identification of the association relationship.

It may be understood that, the address for receiving the seventh information may indicate a destination address, such as a Uniform Resource Identifier (URI) address, of the first function to send the seventh information when notifying the second function of the detected association event, where the type of the address may be determined according to requirements, and the embodiment of the present application is not limited to this. In addition, the format of the address may be determined according to requirements, such as an address in a hypertext transfer protocol (HTTP) format, which is not limited in the embodiment of the present application.

In practical application, the specific content included in the seventh information may be determined according to the requirement, which is not limited in the embodiment of the present application.

According to the scheme provided by the embodiment of the application, the network function (namely the first function) acquires and stores the association relation between the terminal and the resident gateway, and can execute related operation based on the association relation, so that the perception of the network side on the associated terminal under the resident gateway is realized, namely the perception of the network side on the association relation between the terminal and the resident gateway is realized, and the network side can realize the cooperation of the resident gateway and the terminal based on the association relation between the terminal and the resident gateway, thereby better meeting the service requirements of the terminal, such as meeting the functional requirements corresponding to the problems 1 and 2.

The application is described in further detail below in connection with application examples.

In this application example, the terminal includes a 5G terminal, denoted as 5G UE; the residential gateway comprises a 5G residential gateway, which is expressed as 5G-RG; the first function includes UDM; the second function comprises AMF/SMF; the third function includes AF/AMF.

In the application example, based on the architecture 2 and the architecture 3, through information interaction between the 5G-RG/5G UE and the 5G network, related network elements (namely UDM and AMF/SMF) in the 5G network can sense the association relation and association state between the 5GUE and the 5G-RG. Specifically, as shown in fig. 10, the overall flow of the 5G network aware 5G-RG downlink 5G UE may include the following steps:

Step 1010: configuring the association relation;

step 1020: the association relation search and the event subscription;

step 1030: event notifications are associated.

Wherein step 1010 comprises two sub-steps:

step 1011: reporting the association relation between the 5G UE and the 5G-RG to the UDM by the 5G UE/5G-RG;

Step 1012: a heartbeat mechanism between the 5G-RG and the 5G UE is initiated.

Step 1020 includes two sub-steps:

Step 1021: AMF/SMF searches the association relation between 5G-RG and 5G-UE;

Step 1022: AMF/SMF subscribes to the association events of 5G UE and 5G-RG.

Step 1030 includes two sub-steps:

Step 1031: the 5G-RG/5G UE reports the association event between the 5G UE and the 5G-RG;

Step 1032: the UDM notifies the AMF/SMF of the association event of the 5G UE with the 5G-RG.

In step 1011, the 5G UE/5G-RG may report the association between the 5G UE and the 5G-RG to the 5GC, and the UDM stores the association, and then step 1012 is performed. In addition, step 1011 may be implemented based on at least three reporting channels of the association relationship between the 5G UE and the 5G-RG, i.e. step 1011 may include at least the following three implementations: specific implementations of the three methods are referred to in fig. 11, fig. 12, fig. 13 and related descriptions respectively, in a manner of reporting network capability openly (i.e., the above-described manner 1), in a manner of reporting via a wired network (i.e., the above-described manner 2), and in a manner of reporting via a wireless network (i.e., the above-described manner 3).

In step 1012, the 5G-RG needs to initiate a heartbeat mechanism with the 5G UE according to the response message (i.e., the second information) or the indication message (i.e., the tenth information) issued by the 5G.

In step 1021, the AMF/SMF may retrieve the association between the 5G UE and the 5G-RG from the UDM, so as to implement a specific flow process, for example, to solve the above problem 1, and issue N3IWF selection information for the 5G UE; for another example, the 5G UE and the 5G-RG are mutually coordinated in terms of policies and flows related to access management, session management, user plane management, and the like.

In step 1022, the AMF/SMF may subscribe to the UDM for the association event between the 5G UE and the 5G-RG, so that when the association state between the 5G UE and the 5G-RG changes, such as association disconnection, association cancellation (i.e. association suspension), etc., the AMF/SMF may be notified in time, so that corresponding processing may be performed. The specific implementation of step 1021 and step 1022 is shown in fig. 14 and related description.

In step 1031, the 5G-RG/5G UE may generate an association event based on the heartbeat mechanism, report the generated association event to the 5GC, and save the association event by the UDM. Meanwhile, in step 1032, the UDM may notify all AMFs/SMFs subscribed to the association event, and trigger corresponding processing flows of the AMFs/SMFs. The specific implementation of step 1031 and step 1032 is shown in fig. 15 and described in association therewith.

The three above-described implementations of step 1011 are described below in connection with fig. 11-13.

In this application example, when step 1011 is implemented by means of network capability open reporting (i.e. mode 1 above), a unified management platform (i.e. the first platform above) of the 5G-RG and the 5G UE may be deployed on a public server or cloud, and an AF may be deployed on the platform, and the AF may dock with the NEF, so as to use the network capability open function of the 5G. Specifically, as shown in fig. 11, the procedure of reporting the association relationship between the 5G UE and the 5G-RG through the network capability opening may include the following steps:

step 1101: the 5G UE establishes connection with the 5G-RG, and then step 1102 is executed;

step 1102: the 5G UE reports the registration information (i.e. the eleventh information) to the 5G-RG, and then performs step 1103;

step 1103: the 5G-RG reports the association relationship between the 5G UE and the 5G-RG to the management platform, and then step 1104 is executed;

Step 1104: the AF on the management platform calls the API of NEF, configures the association relation between 5G UE and 5G-RG to 5GC, and then executes step 1105;

step 1105: the NEF sends the association of the 5G UE and the 5G-RG to the UDM, and then performs step 1106;

step 1106: the UDM sends a configuration response message (i.e. the second information described above) to the NEF, after which step 1107 is performed;

step 1107: the NEF forwards the configuration response message to the management platform (AF), after which step 1108 is performed;

Step 1108: the management platform transmits a registration response message (which may include at least the second information and/or the ninth information) to the 5G-RG, and then performs step 1109;

step 1109: the 5G-RG sends a registration response message (which may contain at least the ninth information) to the 5G-UE, and then performs step 1110;

step 1110: the 5G-RG and 5G-UE start the heartbeat mechanism.

In step 1101, the 5G UE and the 5G-RG may establish connection through other access modes except 5G, such as Wi-Fi, bluetooth, wired, zigbee, lora, WLAN, HDMI, and other non-3 GPP access modes.

In step 1102, the content carried by the registration information (i.e., the eleventh information) reported by the 5G UE to the 5G-RG may include at least one of the following: 5G UE identity (i.e. the second identity) 5G capability indication (i.e. the twelfth information).

In step 1103, the 5G-RG may report the registration information of the 5G UE and the association relationship between the 5G UE and the 5G-RG to the management platform, that is, the information reported by the 5G-RG to the management platform may include the first information and the twelfth information; in other words, the content carried by the information reported by the 5G-RG to the management platform may include at least one of: 5G-RG identity (i.e. the third identity described above), 5G UE identity, 5G capability indication.

In step 1104, the content carried by the information sent by the AF on the management platform to the NEF (i.e. the first information described above) may include at least one of the following: cell type indication (i.e., the third information described above), 5G-RG identification, 5G UE identification. In addition, it can be understood that, in order to ensure network security, before executing the step, the management platform may perform identity authentication on the 5G UE first, execute the step after the identity authentication is passed, and not execute the step and the subsequent steps if the identity authentication is not passed.

In step 1105, after the identity and authority authentication of the management platform are completed, the NEF may send the association relationship between the 5G UE and the 5G-RG to the UDM, that is, forward the first information.

In step 1106, the UDM may generate an association ID (i.e. the first identifier) for the association between the 5G UE and the 5G-RG, and default the association status of the association to be "normal"; then, the UDM may save the association ID, the 5G UE identifier, the 5G-RG identifier, and the association status as an association record in the UDR, and then send a configuration response message (i.e. the second information) to the NEF. In addition, the content carried by the configuration response message sent by the UDM to the NEF may include at least one of: the result (i.e., whether or not it was successfully saved) is saved, the association ID.

In step 1108, the registration response message sent by the management platform to the 5G-RG may at least include the second information and/or the ninth information, that is, the content carried in the registration response message may include at least one of the following: as a result of registration, the relationship ID (i.e., the second information) and the heartbeat configuration (i.e., the ninth information) are associated. Wherein the heartbeat configuration may include at least one of: the heartbeat interval duration (i.e., the first duration), the heartbeat timeout timer duration (i.e., the second duration), and the association suspension timer duration (i.e., the third duration).

In step 1109, the registration response message sent by the 5G-RG to the 5G-UE may at least contain the ninth information, that is, the content carried by the registration response message may include at least one of the following: as a result of registration, heartbeat configuration (i.e., the ninth information described above). Wherein the heartbeat configuration may include at least one of: the heartbeat interval duration (i.e., the first duration), the heartbeat timeout timer duration (i.e., the second duration), and the association suspension timer duration (i.e., the third duration).

In step 1110, a heartbeat mechanism may be initiated between the 5G-RG and the 5G-UE according to the heartbeat configuration described above.

In this application example, when step 1011 is implemented by a wired network reporting method (i.e., the above-mentioned method 2), the 5G-RG may be connected to the 5G network through the wired network, and after the 5G UE accesses the 5G-RG, the 5G-RG may report the association relationship between the 5G UE and the 5G UE to the 5G network based on NAS signaling. Specifically, as shown in fig. 12, the procedure of reporting the association relationship between the 5G UE and the 5G-RG through the wired network may include the following steps:

Step 1201: the 5G UE establishes a connection with the 5G-RG, and then step 1202 is executed;

Step 1202: the 5G UE reports the registration information (i.e. the eleventh information) to the 5G-RG, and then step 1203 is executed;

Step 1203: the 5G-RG reports the association relationship between the 5G UE and the 5G-RG to the AMF through the N1 interface, and then step 1204 is executed;

Step 1204: the AMF sends the association between the 5G UE and the 5G-RG to the UDM, and then step 1205 is executed;

Step 1205: the UDM sends a configuration response message (i.e. the second information described above) to the AMF, after which step 1206 is performed;

Step 1206: the AMF forwards the configuration response message to the 5G-RG, followed by step 1207;

step 1207: the 5G-RG sends a registration response message (which may contain at least the ninth information described above) to the 5G-UE, after which step 1208 is performed;

Step 1208: the 5G-RG and 5G-UE start the heartbeat mechanism.

In step 1201, the 5G UE and the 5G-RG may establish connection through other access modes than 5G, such as Wi-Fi, bluetooth, wired, zigbee, lora, WLAN, HDMI, and other non-3 GPP access modes.

In step 1202, the content carried by the registration information (i.e., the eleventh information) reported by the 5G UE to the 5G-RG may include at least one of the following: 5G UE identity (i.e. the second identity) 5G capability indication (i.e. the twelfth information).

In step 1203, the content carried by the information reported by the 5G-RG to the AMF (i.e. the first information described above) may include at least one of the following: the 5G UE identity, cell type indication (i.e. the third information described above).

In step 1205, the UDM may generate an association ID (i.e. the first identifier) for the association between the 5G UE and the 5G-RG, and default the association status of the association to be "normal"; then, the UDM may save the association ID, the 5G UE identifier, the 5G-RG identifier, and the association status as an association record in the UDR, and then send a configuration response message (i.e., the second information) to the AMF. In addition, the content carried by the configuration response message sent by the UDM to the AMF may include at least one of: the result (i.e., whether or not it was successfully saved) is saved, the association ID.

In step 1207, the registration response message sent by the 5G-RG to the 5G-UE may at least contain the ninth information, that is, the content carried in the registration response message may include at least one of the following: as a result of registration, heartbeat configuration (i.e., the ninth information described above). Wherein the heartbeat configuration may include at least one of: the heartbeat interval duration (i.e., the first duration), the heartbeat timeout timer duration (i.e., the second duration), and the association suspension timer duration (i.e., the third duration).

In step 1208, a heartbeat mechanism may be initiated between the 5G-RG and the 5G-UE according to the heartbeat configuration described above.

In this application example, when step 1011 is implemented by the wireless network reporting method (i.e., the above-mentioned method 3), the 5G UE may be directly connected to the 5G network through the 5G base station, and report the association relationship between the UE and the 5G-RG to the 5G network based on NAS signaling, in addition to accessing the 5G-RG. Specifically, as shown in fig. 13, the procedure of reporting the association relationship between the 5G UE and the 5G-RG through the wireless network may include the following steps:

Step 1301: the 5G UE establishes a connection with the 5G-RG, and then step 1302 is performed;

Step 1302: the 5G UE obtains the 5G-RG identifier (i.e. the third identifier), and then executes step 1303;

Step 1303: the 5G UE reports the association relation between the 5G UE and the 5G-RG to the AMF through the N1 interface, and then step 1304 is executed;

Step 1304: the AMF sends the association between the 5G UE and the 5G-RG to the UDM, and then step 1305 is executed;

step 1305: the UDM sends a configuration response message (i.e. the second information described above) to the AMF, after which steps 1306 and 1307 are performed;

Step 1306: the AMF forwards the configuration response message to the 5G UE;

Step 1307: the AMF sends a heartbeat mechanism start indication (i.e. the tenth information) to the 5G-RG via the N1 interface, and then performs step 1308;

Step 1308: the 5G-RG sends the heartbeat configuration (namely the ninth information) to the 5G UE according to the 5G UE identification, and then step 1309 is executed;

Step 1309: the 5G-RG and 5G-UE start the heartbeat mechanism.

In step 1301, the 5G UE and the 5G-RG may establish connection through other access modes except 5G, such as Wi-Fi, bluetooth, wired, zigbee, lora, WLAN, HDMI, and other non-3 GPP access modes.

In step 1302, the 5G UE may obtain the identifier of the 5G RG through ANQP protocol query or the like.

In step 1303, the 5G UE may establish a connection with the 5GC through the 5G RAN. In addition, the content carried by the information reported by the 5G UE to the AMF (i.e., the first information described above) may include at least one of the following: 5G-RG identification (i.e. the third identification) and cell type indication (i.e. the third information).

In step 1305, the UDM may generate an association ID (i.e. the first identifier) for the association between the 5G UE and the 5G-RG, and default the association status of the association to be "normal"; then, the UDM may save the association ID, the 5G UE identifier, the 5G-RG identifier, and the association status as an association record in the UDR, and then send a configuration response message (i.e., the second information) to the AMF. In addition, the content carried by the configuration response message sent by the UDM to the AMF may include at least one of: the result (i.e., whether or not it was successfully saved) is saved, the association ID.

In step 1307, the AMF may send a heartbeat mechanism start indication message to the 5G-RG according to the 5G-RG identifier reported by the 5G UE, where the message is used to indicate that the heartbeat mechanism is started between the 5G-RG and the specified 5G UE, and the content carried in the message may include at least one of the following: association ID,5G UE identity, heartbeat mechanism start indication (i.e. tenth information described above).

In step 1308, the heartbeat configuration (i.e., the ninth information described above) sent by the 5G-RG to the 5G-UE according to the 5G UE identity may include at least one of: the heartbeat interval duration (i.e., the first duration), the heartbeat timeout timer duration (i.e., the second duration), and the association suspension timer duration (i.e., the third duration).

In step 1309, a heartbeat mechanism may be initiated between the 5G-RG and the 5G-UE according to the heartbeat configuration described above.

Specific implementations of steps 1021 and 1022 are described below in conjunction with fig. 14.

In this application example, the association relationship between the 5G UE and the 5G-RG is stored in the UDM, and the AMF/SMF needs to retrieve the association relationship from the UDM for access management and session management of the 5G UE and the 5G-RG, so as to solve the above problem 1 and/or problem 2. Meanwhile, AMF/SMF needs to be able to timely sense the association relation and change of association state between 5G UE and 5G-RG, so as to timely adjust access management and session management policies, flows and the like, and ensure normal operation of service. Specifically, as shown in fig. 14, the association query (i.e., search) process (i.e., step 1021) may include the following steps:

Step 1401: the AMF/SMF searches the association relation between the 5G UE and the 5G-RG to the UDM, and then step 1402 is executed;

Step 1402: the UDM returns the association relation between the 5G UE and the 5G-RG to the AMF/SMF.

The event subscription procedure (i.e. step 1022) of the association relationship may specifically include the following steps:

step 1403: AMF/SMF subscribes to UDM for the event notification associated with 5G UE and 5G-RG, then executing step 1404;

step 1404: the UDM sends a subscription response to the AMF/SMF.

In step 1401, the AMF/SMF may retrieve the association between the 5G UE and the 5G-RG from the UDM by sending the fourth information to the UDM, where the retrieval condition may include one or a combination of the following: 5G UE identification, 5G-RG identification and association state;

in step 1402, the UDM may query, from the UDR, an association record of the 5G UE and the 5G-RG that meets the search condition, for example: when the 5G UE identification is taken as a search condition, only one or a few records can be recorded; the 5G-RG identifier may be used as a search condition to search out a plurality of association records (such as all records of the 5G-RG) related to the 5G-RG. Additionally, the fields of each record may include, but are not limited to: association ID,5G-RG identity, 5G UE identity, association status.

In step 1403, the AMF/SMF may subscribe association events of the association relationships to the UDM for the association relationships between the 5G UE and the 5G-RG queried in step 1402, where the content carried by the subscription message (i.e. the sixth information) may include, but is not limited to: the associated event identifier is used for receiving the URI address and the associated relation ID of the notification (namely the seventh information) of the subscribed event.

In step 1404, the UDM can record the subscription information and return a subscription response message to the AMF/SMF. And the UDM can send the notification of the event subscribed by the AMF/SMF to the URI address according to the recorded subscription information.

Specific implementations of steps 1031 and 1032 are described below in conjunction with fig. 15.

In the present application example, considering that the 5G fixed-mobile convergence architecture is in actual deployment, the following differences exist between the 5G-RG and the 5G UE:

first, 5G-RG is accessed to 5GC through a wired network, 5G UE is accessed to 5G-RG through a wireless network (such as Wi-Fi, bluetooth, etc.); wireless networks are susceptible to interference, are prone to being obscured, and signal quality is greatly affected by distance from the signal source relative to wired networks.

Second, the 5G-RG is powered by a continuous power supply, and the 5G UE is powered by a battery, so that abnormal conditions such as reduction of the transmitting power and even shutdown are easy to occur due to insufficient battery power.

Third, 5G-RGs are typically deployed in fixed locations, while 5G UEs are often in motion, and when moving from the coverage area of one 5G-RG to the coverage area of another 5G-RG, the 5G UE may disconnect from the original 5G-RG and access the new 5G-RG.

As can be seen from the above description, the stability and reliability of the 5G-RG are relatively higher than those of the 5G UE, based on which, in the present application example, the association event is detected by the 5G-RG based on the heartbeat mechanism with the 5G UE and reported to the 5GC. Specifically, as shown in fig. 15, the associated event notification flow may include the steps of:

Step 1501: the 5G-RG detects the association event, then step 1502 is performed;

step 1502: the 5G-RG reports the associated event to the UDM, then step 1503 is performed;

Step 1503: the UDM modifies the association record, then performs step 1504 and step 1505;

Step 1504: the UDM sends an associated event notification (i.e., the seventh information) to the AMF/SMF;

step 1505: the UDM sends a response message to the 5G-RG.

Step 1501 and step 1502 correspond to step 1031; step 1504 corresponds to step 1032.

Specifically, in step 1501, the 5G-RG may detect the association event of the 5G UE with the 5G-RG based on the heartbeat mechanism, i.e., the association event based on the heartbeat configuration (i.e., the ninth information). Specifically, the association event detected by the 5G-RG may include, but is not limited to:

An association disconnection event (i.e. the first event) can be triggered when the duration that the 5G-RG continuously does not receive the heartbeat message sent by the 5G UE exceeds the duration of the heartbeat timeout timer (i.e. the second duration), i.e. the 5G-RG detects the association disconnection event;

An association recovery event (namely the third event) is triggered, after the association disconnection event is triggered, the 5G-RG receives the heartbeat message of the 5G UE again, and the association recovery event is triggered, namely the association recovery event is detected by the 5G-RG;

And triggering an association suspension disconnection event (namely the second event) when the duration of the heartbeat message which is not received by the 5G-RG and sent by the 5G UE exceeds the duration of the association suspension timer (namely the third duration), namely the 5G-RG detects the association suspension event.

In step 1502, the 5G-RG may report the detected 5G UE and 5G-RG association event to the UDM through an association event message (i.e., the eighth information described above), where the content carried in the message may include, but is not limited to: the association relationship ID (i.e., the first identifier) associates the event identifier (i.e., the fourth identifier). In addition, the manner in which the 5G-RG reports the associated event message to the UDM may correspond to the manner in which the association relationship between the 5G UE and the 5G-RG is reported, and in the case in which step 1011 is implemented by the manner in which the network capability is opened for reporting (i.e., the foregoing manner 1), the 5G-RG may report the associated event message to the management platform, and the AF on the management platform may call the API of the NEF to send the associated event message to the NEF, where the NEF sends the associated event message to the UDM; in the case of implementing step 1011 by means of wired network reporting (i.e. mode 2 above), the 5G-RG can report the associated event message to the AMF via the N1 interface (intermediate forwarding via the W-AGF), which forwards it to the UDM; in the case of implementing step 1011 by means of wireless network reporting (i.e. mode 3 above), since the 5G-RG is still accessing the 5GC through the wired network, the 5G-RG can still report the associated event message to the AMF through the N1 interface (intermediate forwarding via the W-AGF), which is forwarded to the UDM.

In step 1503, after receiving the association event message sent by the 5G-RG, the UDM may retrieve a corresponding association record according to the association ID in the association event message, and may perform corresponding processing for different association events. Under the condition that the association event identifier in the association event message represents an association disconnection event, the UDM can modify the association state in the corresponding association relationship record into a disconnection state; under the condition that the association event identifier in the association event message represents an association recovery event, the UDM can modify the association state in the corresponding association relationship record into a normal state; in case the association event identity in the association event message represents an association suspension event, the UDM may delete the corresponding association relationship record.

In step 1504, the UDM may send an association event notification (i.e. the seventh information mentioned above) to the AMF/SMF subscribed to the association event of the 5G UE and the 5G-RG association (i.e. the association event detected by the 5G-RG in step 1501), where the notification content may include at least one of the following: the association relationship ID and the association event identification.

The scheme provided by the application example can enable the 5G network to perceive the 5G-RG downlink 5G UE, namely, the association relation between the 5G-RG and the 5G UE, so that the cooperation of the 5G-RG and the 5G UE can be realized based on the relation later, and the service requirement of the 5G UE can be better served. In addition, by ensuring the perception of the wireless network to the associated UE with the 5G communication capability under the 5G-RG, the network security can be improved, the manageability and controllability of the 5G network to the accessed UE are ensured, and the service quality of the 5G network and the 5G-RG is further improved.
