Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

First, a relationship between a Domain Name Server (DNS) and a conventional Evolved Packet Core (EPC) network in a conventional mobile communication network is described below: as shown in fig. 1, the schematic diagram of the structure between the DNS and the EPC Network is shown, where, for example, when a Mobility Management Entity (MME) is attached, the DNS generates an old MME domain Name according to a received Globally Unique Temporary UE Identity (GUTI) of a terminal (UE) to query an address of the old MME, so as to implement communication between the new MME and the old MME, or when a Public Data Network (PDN) is connected, the DNS generates domain names according to a Tracking Area (Tracking Area, TA) and an Access Point (Access Point Name, APN) to implement querying of addresses of a Serving GateWay (SGW) and a Public Data GateWay (PDN, SGW), so as to implement communication between the MME and the SGW. In a conventional General Packet Radio Service (GPRS) or EPC network, on one hand, a DNS is not a part of the network, and on the other hand, to implement access between network elements, a large amount of domain name data is generally required to be configured on the DNS to implement domain name resolution, and meanwhile, changing information of some network elements, such as adding interface support, may also require changing domain name configuration on the DNS, thereby bringing a large amount of workload for operation and maintenance of the network.

As shown in fig. 2, there is no DNS in the 5G Network, and the UE may communicate with AN Access and Mobility Management Function (AMF), may communicate with the AMF through a (Radio) Access Network (R) AN, may communicate with a User Plane Function (UPF), and may use a Data Network (DN) through the UPF, or may communicate with a Session Management Function (SMF) through the UPF; an Authentication Server Function (AUSF), an AMF, an SMF, a Network open Function (NEF), an NRF, a Policy Control Function (PCF), a Unified Data Management (UDM), an Application Function (AF), and the like are connected to their respective interfaces and Application buses to implement information interaction. The NF comprises functions realized by AUSF, AMF, SMF and the like. The invention provides that the function corresponding to NF is registered in NRF, and the NRF generates and stores the corresponding domain name record when the function corresponding to NF is registered.

Based on the system architecture of the 5G network shown in fig. 2, an embodiment of the present invention provides an information processing method, which, referring to fig. 3, includes the following steps:

step 101, receiving a first registration request sent by a first function.

The first function is mainly used for realizing a network management function, and the first registration request carries a first characteristic parameter of the first function.

In this embodiment of the present invention, the receiving of the first registration request sent by the first function in step 101 may be implemented by NRF. The first function comprises functions of AMF, SMF or MME and the like. The first registration request is a registration request transmitted to the NRF when the first function is to automatically register in the NRF; the first function may send a registration request to the NRF when the first function registers to the NRF for the first time, or may send a registration request to the NRF after a certain time interval to keep the first function discoverable by the UE or the base station. The first characteristic parameter is resource record information of the first Function, and includes an NF type to which the first Function belongs, a Public Land Mobile Network (PLMN) to which the first Function belongs, a Network Function Identity (NFID) of the first Function, an Internet Protocol (IP) address and port information, and resource record name information supported by the first Function.

Step 102, according to the first registration request, generating a first domain name corresponding to the first function and a domain name record corresponding to the first domain name based on the first characteristic parameter.

In this embodiment of the present invention, the step 102 of generating a first domain name corresponding to the first function and a domain name record corresponding to the first domain name based on the first characteristic parameter according to the first registration request may be implemented by NRF. The domain name record corresponding to the first domain name is a DNS domain name record, and includes a Name Authority Pointer (NAPTR) resource record, a service location (SRV) resource record, and a HOST (HOST) resource record. The NRF generates a first domain name of the first function and a domain name record corresponding to the first domain name based on the first characteristic parameter of the first function carried in the first registration request.

Step 103, sending a registration response for indicating that the registration is successful to the first function.

And the registration response is used for indicating the source AMF to generate a second domain name corresponding to the received first operation request and acquiring a domain name record corresponding to the second domain name from a domain name record corresponding to the first domain name when the first function is a source access and mobility management function (AMF).

In the embodiment of the present invention, the step 103 of sending the registration response indicating that the registration is successful to the first function may be implemented by NRF. After the NRF generates a domain name record for the first function, it sends a registration response to the first function to enable the NRF to discover the first function in subsequent operations.

After receiving a first registration request sent by a first function, generating a first domain name corresponding to the first function and a domain name record corresponding to the first domain name according to the first registration request and based on a first characteristic parameter, and finally sending a registration response for indicating successful registration to the first function; therefore, the NRF receives the first registration request sent by the first function, and automatically generates the first domain name corresponding to the first function and the domain name record corresponding to the first domain name according to the first registration request sent by the first function, so that the problem that the scheme that the NRF can not discover the NF in the prior art is solved, the generation of the DNS record by the NRF according to the automatic registration process of the NF is realized, and the function that the NRF automatically discovers the NF is ensured.

Based on the foregoing embodiments, an embodiment of the present invention provides an information processing method, which is shown in fig. 4 and includes the following steps:

step 201, after receiving a registration response sent by the NRF and used for indicating that the registration is successful, receives a first operation request.

The first operation request carries identification information.

In this embodiment of the present invention, after receiving the registration response sent by the NRF and indicating that the registration is successful in step 201, receiving the first operation request may be implemented by the source AMF. The first operation request may be sent by a device, such as a UE or a base station, to the source AMF, and is used to request the source AMF to perform a corresponding first operation, for example, an update registration procedure or a handover procedure may be performed. Note that the source AMF is an AMF currently serving a device such as a UE or a base station.

Step 202, generating a domain name with a second function based on the identification information to obtain a second domain name, and sending a query request carrying the second domain name to the NRF.

In this embodiment of the present invention, step 202 generates the domain name of the second function based on the identification information to obtain the second domain name, and sends the query request carrying the second domain name to the NRF, which may be implemented by the source AMF. The identification information may be related characteristic information of the UE or characteristic information of the base station, and may include, for example, identity information of the UE and temporary identification information of the UE, or identification information of a target base station to which handover is required. The second function comprises a target AMF or SMF; it may be a function of allocating a temporary identity to the UE or a function of being able to process a service related to the target base station. And the source AMF generates a domain name of the second function according to the received identification information based on the generation rule of the domain name. In different application scenarios, the target AMF is different, in some application scenarios, the target AMF is an AMF that serves a device such as a UE or a base station before the source AMF, and in some application scenarios, the target AMF is an AMF that is determined by the source AMF and is to serve the device such as the UE or the base station.

Step 203, receiving a domain name record corresponding to the second domain name sent by the NRF, and establishing a communication link with the second function based on the domain name record corresponding to the second domain name.

And the domain name record corresponding to the second domain name is obtained by the NRF based on the second domain name in the received query request.

In this embodiment of the present invention, the step 203 receives the domain name record corresponding to the second domain name sent by the NRF, and establishing the communication link with the second function based on the domain name record corresponding to the second domain name may be implemented by the source AMF. And after receiving the second domain name record sent by the NRF, the source AMF determines a second function based on the second domain name record and establishes a communication link with the second function, so that the communication link between the UE or the base station and the second function is realized.

In the information processing method provided by the embodiment of the present invention, after receiving a registration response sent by an NRF and used for indicating successful registration, and after receiving a first operation request, a source AMF generates a domain name of a second function based on identification information to obtain a second domain name, sends a query request carrying the second domain name to the NRF, receives a domain name record corresponding to the second domain name sent by the NRF, and establishes a communication link with the second function based on the domain name record corresponding to the second domain name; therefore, after the source AMF is registered in the NRF, the source AMF can receive the first operation request, generate a second domain name of the second function according to the identification information carried in the first operation request, acquire a domain name record corresponding to the second domain name from the NRF, and establish a communication link with the second function according to the domain name record, so that the problem that the scheme that the NRF can not discover the NF in the prior art is solved, the NRF can generate the DNS record according to the automatic registration process of the NF, and the function that the NRF automatically discovers the NF is ensured.

Based on the foregoing embodiments, an embodiment of the present invention provides an information processing method, which is mainly used in an application scenario in which a first function is registered in an NRF, so that the first function can be quickly discovered subsequently, as shown in fig. 5, the method includes the following steps:

step 301, the NRF receives a first registration request sent by the first function.

In the embodiment of the present invention, the first feature parameter includes a resource record name and an identity of the first function. Taking the example that the first function is AMF, when the first function is any AMF, the content carried in the first registration request includes that the NF type is AMF, the PLMN where the AMF is located, NFID, IP and port information of the AMF, and a resource record name supported by the AMF, including but not limited to a supported TA, a supported Network Slice Identity (NSI), an AMF domain, an AMF set, and an AMF Identity.

When the AMF is automatically registered in the NRF, the AMF sends a first registration request to the NRF to initiate a registration process. The first characteristic parameter carried in the first registration request includes: the PLMN to which the AMF belongs may be denoted as mncxxx.mccxxx, for example; the identity NFID to which the AMF belongs may be, for example, AMF 001-N14; the resource record name corresponding to the AMF includes TA identifier, NSI, IP address corresponding to host (Adress, a), AMF domain, AMF set, AMF identifier, etc., where the TA identifier may be denoted as tac-lbxx.tac-hbxx.tac, the NSI may be denoted as NSIxxx, the IP address corresponding to a may be 10.10.10.10, the AMF domain, AMF set, and AMF identifier may be recorded together, and the AMF domain, AMF set, and AMF identifier may be in form of fromigionxxx.amfsetxxx.amfpointerxxx; wherein AMFREGeionxxx may represent the AMF domain, AMFSetxxx may represent the AMF set, and AMFREGeionxxx may represent the AMF identification. It should be noted that "x" in the above identifiers may be replaced according to actual situations in the actual use process, and may be a specific number or the like.

Wherein, the steps 302-305 can be executed simultaneously;

step 302, the NRF generates a first domain name for the first function according to the first registration request.

In the embodiment of the present invention, in response to a first registration request sent by the AMF, the NRF may generate a first domain name according to PLMN information mncxxx.mccxxx carried in the first registration request and according to a predetermined format, for example, the predetermined format of the first domain name is amf.5g.mncxxx.mccxxx.3gppnetwork.org.

Step 303, NRF obtains the name authority pointer NAPTR record based on the resource record name and the identity of the first function.

In this embodiment of the present invention, the identity of the first function is NFID, and one code representation form of NAPTR record may be: resource record name IN NAPTR mn "s" "x-3 gpp-amf: x-N14" NFID. Wherein m represents an order, n represents a priority, and m and n may be changed according to a specific configuration; in x-3gpp-AMF: x-N14, x-3gpp-AMF: x is the agreed communication protocol, N14 is the interface identifier of AMF, and the rest is the agreed format.

Illustratively, if the resource record name of the AMF includes: the AMF domain, the AMF set, and the AMF identifier may be represented as amfpxxx, amfsetxxx, amfreguexxxx, the NFID of AMF is AMF001-N14, and the NAPTR record obtained by using the AMF domain, the AMF set, the AMF identifier, and the NFID of AMF may be: AMFPxxx, AMFSetxxx, AMFRegionxxx IN NAPTR 100100 "s" "," x-3gpp-AMF x-N14 "AMF 001-N14 AMFPxxx, AMFSetxxx, AMFRegionxxx;

NAPTR records derived using the resource record name TA identification of the AMF (i.e., tac-lbxx. tac-hbxx. tac) and the NFID of the AMF (i.e., AMF001-N14) may be: tac-lbxx.tac-hbxx.tac IN NAPTR 100100 "s" "x-3 gpp-AMF x-N14" AMF001-N14. tac-lbxx.tac-hbxx.tac;

the NAPTR records obtained using the resource record name NSI of AMF (i.e., NSIxxx) and the NFID of AMF (i.e., AMF001-N14) may be: NSIxxx IN NAPTR 100100 "s" "" x-3gpp-AMF: x-N14 "AMF 001-N14. NSIxxx.

And step 304, the NRF processes the resource record name and the identity of the first function to obtain the SRV record of the service position.

In the embodiment of the present invention, one code expression form of the SRV record may be: NFID resource record name IN SRV lp 2123 NFID; where l is the priority weight, p is the priority, and l and p may change according to the specific configuration.

For example, the SRV record obtained using the resource record name of the AMF (i.e., amfpxxx. amfsetxxx. amfregemonxxx) and the NFID of the AMF (i.e., AMF001-N14) may be: AMF001-N14.AMFPxxx. AMFSetxxx. AMFRegionxxx IN SRV 10102123 AMF 001-N14;

the SRV records obtained by using the resource record name TA identification (i.e., tac-lbxx. tac-hbxx. tac) of the AMF and the NFID (i.e., AMF001-N14) of the AMF can be: AMF001-N14.tac-lbxx. tac-hbxx. tac IN SRV 10102123 AMF 001-N14;

the SRV records obtained using the resource record name NSI (i.e., NSIxxx) of AMF and the NFID (i.e., AMF001-N14) of AMF may be: AMF001-N14.NSIxxx IN SRV 10102123 AMF001-N14.

Step 305, NRF obtains HOST record based on the identity of the first function and the protocol IP address of the interconnection between the networks of the first function.

In the embodiment of the present invention, one code expression form of the HOST record may be: NFID IN AIP, respectively; where a identifies the host (Adress).

Obtaining HOST records by adopting the IP address corresponding to the HOST A of the AMF and the NFID of the AMF: AMF001-N14 IN A10.10.10.10.

Step 306, the NRF sends a registration response to the first function indicating that the registration was successful.

And the registration response is used for indicating the source AMF to generate a second domain name corresponding to the received first operation request and acquiring a domain name record corresponding to the second domain name from a domain name record corresponding to the first domain name when the first function is the source AMF.

It should be noted that, for the explanation of the same steps or concepts in the present embodiment as in the other embodiments, reference may be made to the description in the other embodiments, and details are not described here.

Based on the foregoing embodiment, an embodiment of the present invention further provides an information processing method, in the embodiment of the present invention, a source AMF has registered in an NRF by using a network method provided in the foregoing embodiment of the present invention, and domain name records corresponding to the source AMF, a second function, and the like have been generated in the NRF, and referring to fig. 6, the method includes the following steps:

step 401, after receiving a registration response sent by the NRF and used for indicating that the registration is successful, the source AMF receives a first operation request.

The first operation request carries identification information.

In the embodiment of the present invention, after the source AMF successfully registers in the NRF, the source AMF may receive a first operation request sent by the UE for requesting an update of a registration procedure or a first operation request sent by the base station for requesting a handover of the base station. The corresponding first operation request sent by the UE carries the GUTI of the UE, and the first operation request sent by the base station carries the identity information of the target base station. That is, the identification information carried in the first operation request includes temporary identification information of the UE or identity identification information of the target base station.

Step 402, the source AMF generates a domain name with a second function based on the identification information to obtain a second domain name, and sends a query request carrying the second domain name to the NRF.

In the embodiment of the present invention, the source AMF generates the domain name with the second function according to the identification information and a certain format to obtain the second domain name.

In step 403, the NRF receives a query request sent by the source AMF for indicating a domain name query.

And the query request carries the second domain name.

And step 404, the NRF queries the domain name record based on the second domain name according to the query request to obtain the domain name record corresponding to the second domain name.

In the embodiment of the present invention, the NRF obtains the domain name records AMF001-N14 of the SRV type from step 304 according to the domain name record of the NAPTR type, and finally obtains the HOST record 10.10.10.10 from step 305 according to the domain name record of the SRV type when the query request sent by the AMF, for example, the query request carries the second function, for example, the second domain name of the target AMF, that is, the last AMF providing service for the UE, is amfpxxx.

Step 405, the NRF sends the domain name record corresponding to the second domain name to the source AMF.

In an embodiment of the invention, the NRF may send the obtained HOST record 10.10.10.10, SRV record AMF001-N14 and/or NAPTR record AMF001-N14 amfpxxx amfsetxxx amfregoxxxx to the AMF.

Step 406, the source AMF receives the domain name record corresponding to the second domain name sent by the NRF, and establishes a communication link with the second function based on the domain name record corresponding to the second domain name.

In the embodiment of the present invention, the source AMF may establish a communication link with the target AMF according to the HOST record 10.10.10.10, and continue the subsequent registration update process in the royal city.

In other embodiments of the present invention, step 402 may be implemented by:

step 402a1, if the identification information is not the identification information allocated by the source AMF, the source AMF generates the domain name of the second function based on the identification information to obtain a second domain name.

In the embodiment of the present invention, if the identification information is allocated by the source AMF, the UE or the base station directly communicates with the source AMF without performing subsequent steps, thereby implementing a related communication process.

When the identification information is a GUTI of the UE, for example, the GUTI may be a 5G GUTI allocated after the UE performs registration, and the 5G GUTI may be expressed as <5G-GUTI > < MCC > < MNC > < AMF Region ID > < AMF Set ID > < AMF Pointer > <5G-TMSI >; the source AMF judges whether the GUTI of the UE is self-configured by the source AMF; if the GUTI of the UE is not allocated by the source AMF itself, the source AMF generates a second domain name according to the GUTI of the UE, where the second domain name is determined according to < AMF Region ID > < AMF Set ID > < AMF Pointer > in 5G GUTI, and the second domain name is, for example, amfpxxx.

When the identification information is identity identification information of a base station, a source AMF determines that identity identification information of a target base station carried in a first request sent by a source base station is not in the identity identification information of the base station processed by the source AMF, and the source AMF generates a domain name of the target AMF to obtain a second domain name according to TA information (for example, tac-lbxx.tac-hbxx.tac) and PLMN information (for example, mncxx.mccxxx) in the identity identification information of the target base station; for example, the second domain name is tac-lbxx.tac-hbxx.tac.amf.5g.mncxxx.mccxxx.3gppnetwork.org, the remainder being a fixed format of the 5G domain name.

Step 402a2, the source AMF sends a query request carrying the second domain name to the NRF.

Alternatively, in other embodiments of the present invention, step 402 can also be implemented by the following steps:

step 402b1, the source AMF sends a request instruction to the NSSF for requesting information.

Wherein the request instruction carries identification information.

In an embodiment of the present invention, the request information may be a request instruction for requesting NSI information.

Step 402b2, the source AMF receives the network slice identity NSI sent by the NSSF.

Wherein, NSI is obtained by NSSF based on the identification information carried in the request instruction.

In the embodiment of the present invention, the UDM obtains the corresponding NSI from the UDM based on the received second NSSAI, and sends the corresponding NSI to the source AMF.

Step 402b3, the source AMF generates a second domain name based on the first operation request and the NSI, and sends a query request carrying the second domain name to the NRF.

In an embodiment of the invention, the source AMF responds to the first operation request and generates the second domain name based on the received NSI.

Alternatively, in other embodiments of the present invention, step 402b1 may be implemented by:

a1, the source AMF obtains first network slice selection assistance information NSSAI from the unified data management UDM based on the identity information of the UE.

The identification information includes identity identification information of the UE, and the first NSSAI is a subscription NSSAI of the UE.

A2, if the first NSSAI does not match the second NSSAI carried in the first operation request, the source AMF sends a request command to the network slice selection function NSSF.

In an embodiment of the invention, the second NSSAI is a request NSSAI requested by the UE. The source AMF may decide whether the UE belongs to the source AMF process based on the local policy, the first NSSAI, and the second NSSAI, and if not, the source AMF sends a request instruction carrying the first NSSAI and the second NSSAI to the NSSF.

Accordingly, step 402b3 may be implemented by:

b1, if the first operation request is an initial registration request, the source AMF generates the domain name of the target AMF based on the NSI to obtain a second domain name.

Wherein the second function is the target AMF.

In this embodiment of the present invention, if the first operation request is an initial registration request sent by the UE to the source AMF, the source AMF generates a second domain name of the target AMF with a fixed format according to the received NSI, for example, the second domain name may be nsixxx.amf.5g.mncxxx.mccxxx.3gppnetwork.org, where NSIxxx represents NSI, mnxxx.mccxx is PLMN information, and the rest is a preset fixed format.

B2, the source AMF sends the query request carrying the second domain name to the NRF.

Alternatively, in other embodiments of the present invention, 402b3 may be implemented by:

and C1, if the first operation request is a Protocol Data Unit (PDU) session establishment request, the source AMF acquires a Data Network Name (DNN) carried in the PDU session establishment request.

In the embodiment of the invention, if the first operation request is a PDU session establishment request sent by UE to a source AMF, wherein the PDU session establishment request carries DNN and network slice selection auxiliary information S-NSSAI; the source AMF sends a request instruction carrying S-NSSAI to NSSF to request slice information, the NSSF acquires corresponding NSI based on the S-NSSAI in the request instruction and sends the NSI to the source AMF, and the source AMF acquires DNN carried in the PDU session establishment request.

C2, the source AMF generates the domain name of the SMF based on the NSI and the DNN to get the second domain name.

Wherein the second function is SMF.

In the embodiment of the present invention, the source AMF obtains the second domain name based on the domain name generated by the NSI and the DNN, where the second domain name may be, for example, dnnxxx, nsixxx, smf.5g.mncxxx, mccxxx.3gppnetwork.

C3, the source AMF sends a query request carrying the second domain name to the NRF.
