Background Art

[0002] When a network function (NF) element registers with a network repository function (NRF) element, it needs to carry all the information of the NF element for which registration is requested.

[0003] The registration information of a large number of NF network elements will occupy a large amount of network transmission resources and storage resources of NRF network elements. Summary of the Invention

[0004] Research has found that some NFs have some duplicate registration information. According to the traditional technology, each NF registers separately.

[0060] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure.

[0061] Unless otherwise specified, descriptions such as “first” and “second” in the present disclosure are used to distinguish different objects and are not used to indicate meanings such as size or time sequence.

[0062] Figure 1 A flowchart of a registration method 100 according to some embodiments of the present disclosure is shown.

[0063] like Figure 1 As shown, the registration method 100 of this embodiment includes steps 110-130, and may also include one or more steps 140-190.

[0064] Step 110: The NRF network element receives first registration information sent by the first NF network element, where the first registration information includes characteristic information of the first NF network element and identifiers of one or more target shared information corresponding to the first NF network element.

[0065] The characteristic information of the first NF network element refers to information that is different from other NF network elements (i.e., non-shared information). The characteristic information of the first NF network element includes, but is not limited to, the identifier of the first NF network element and other unique information. Each NF network element is also called an NF instance.

[0066] The types of shared information in the embodiments of the present disclosure include but are not limited to: NF set (Set) information, NF pool (Pool) information, slice information, public land mobile network (PLMN) information, private network sharing information, positioning sharing information, proximity service (ProSe) sharing information, user permanent identifier (SUbscription Permanent Identifier, SUPI) range, stand-alone non-public network (SNPN) sharing information, etc.

[0067] The type of shared information can be deployed and configured by operators / equipment manufacturers based on the type, purpose, and network status of the NF.

[0068] The shared information includes the shared information identifier and the specific shared content. The shared information identifier can be referred to as the "shared identifier" for short.

[0069] In some embodiments, when an NF network element has the same shared content with other NF network elements, an identifier can be dynamically or temporarily assigned according to business needs. The identifier and its shared content dynamically or temporarily form a shared information, but is not limited to the examples given.

[0070] In some embodiments, the multiple target sharing information corresponding to the first NF network element includes identifiers of the multiple target sharing information and different sharing contents respectively shared by the first NF network element and other different NF network elements.

[0071] For example, assume that: a first NF network element shares first target sharing information with one or more fourth NF network elements, but the first target sharing information has not yet been registered; the first NF network element shares second target sharing information with one or more second NF network elements, and the second target sharing information has been registered. The second target sharing information is, for example, NF set A sharing information, which includes NF set AID and NF set A sharing content; and the first NF network element shares third target sharing information with one or more third NF network elements, and the third target sharing information is, for example, slice B sharing information, which includes slice B ID and slice B sharing content. However, this is not limited to the examples given.

[0072] Based on this assumption, according to business needs, the first registration information may include characteristic information of the first NF network element and an identifier of the first target shared information, an identifier of the second target shared information, and an identifier of the third target shared information.

[0073] Step 120: The NRF network element uses the identifier of each target shared information to retrieve the registration information of each target shared information from the registration information of the registered shared information.

[0074] The NRF network element will save the registration information of the registered shared information, including the registered shared information identifier and specific shared content. If the registration information of a target shared information is retrieved from the registered shared information, it means that the target shared information has been registered. Each NF network element corresponding to the target shared information can use the identifier of the target shared information to simplify registration.

[0075] Step 130: The NRF network element returns a response of the first registration information to the first NF network element based on the search result of the registration information of all target shared information.

[0076] In some embodiments, based on the retrieval results of the registration information of all target shared information, the response of returning the first registration information to the first NF network element includes: if the registration information of all target shared information is retrieved and other preset registration success conditions are met, an indication of registration success is returned to the first NF network element.

[0077] Among them, other preset registration success conditions include, but are not limited to, that the first NF network element should have registration authority in the NRF network element, and other related registration success conditions, which can be set according to business needs.

[0078] In some embodiments, based on the retrieval results of the registration information of all target shared information, the response of returning the first registration information to the first NF network element includes: if the registration information of one or more of the first target shared information is not retrieved, returning an indication information of registration failure to the first NF network element, and the indication information of registration failure includes that the reason for the failure is that the first target shared information that was not retrieved is not registered.

[0079] If the registration failure indication information shows that the failure reason is that the first target shared information was not retrieved and not registered, then continue to perform steps 140 - 160 to register the first target shared information.

[0080] Step 140: The NRF network element receives the second registration information sent by the first NF network element, where the second registration information includes characteristic information of the first NF network element, an identifier of the first target shared information, and shared content.

[0081] If the first target shared information corresponds to multiple NFs (for example, the first NF and the fourth NF), the multiple NFs can elect a certain NF to initiate registration of the first target shared information. After successful registration, the other NFs are notified. This avoids a situation where an NF blindly registers using the identifier of an unregistered target shared information.

[0082] In step 150 , the NRF network element stores the identifier of the first target shared information and the shared content in association with each other as the registration information of the first target shared information, thereby completing the registration of the first target shared information.

[0083] Step 160: If the first target shared information is successfully registered and other preset registration success conditions are met, the NRF network element returns a registration success indication to the first NF network element.

[0084] After the shared information is successfully registered, all NF network elements corresponding to the shared information can share the registered information of the shared information without the need for repeated registration. The following describes the registration process of the second NF network element and the third NF network element as an example.

[0085] Then, steps 170a-190a may be executed to register the second NF network element.

[0086] Step 170a: The NRF network element receives the third registration information sent by the second NF network element, where the third registration information includes the characteristic information of the second NF network element and the identifier of the second target shared information.

[0087] Step 180a: The NRF network element uses the identifier of the second target shared information to retrieve the registration information of the second target shared information from the registration information of the registered shared information.

[0088] Step 190a, if the NRF network element retrieves the registration information of all the second target shared information and meets other preset registration success conditions, it returns an indication of successful registration to the second NF network element; otherwise, it returns an indication of failed registration to the second NF network element, and the indication of failed registration includes that the reason for the failure is that the second target shared information that was not retrieved is not registered.

[0089] Then, steps 170b-190b may be executed to register the third NF network element.

[0090] Step 170b: The NRF network element receives the fourth registration information sent by the third NF network element, where the fourth registration information includes characteristic information of the third NF network element and an identifier of the third target shared information.

[0091] Step 180b: The NRF network element uses the identifier of the third target shared information to retrieve the registration information of the third target shared information from the registration information of the registered shared information.

[0092] Step 190b, if the NRF network element retrieves the registration information of all the third target shared information and meets other preset registration success conditions, it returns an indication of successful registration to the third NF network element; otherwise, it returns an indication of failed registration to the third NF network element, and the indication of failed registration includes that the reason for the failure is that the third target shared information that was not retrieved is not registered.

[0093] The disclosed embodiment proposes that the same shared information only needs to be registered once, and proposes a method for hierarchical registration of network elements, which is divided into the registration of characteristic information and shared information. The NF network element completes the registration by providing its own characteristic information and the identifier of the corresponding target shared information to the NRF network element. There is no need to repeatedly provide shared information, which greatly reduces the occupied network transmission resources and storage resources of the NRF network element.
