Technical Field

Background

Generally, in a registration process of a User Equipment (UE), when subscription network slice information (subscribed S-nsais) in a Unified Data Management (UDM) network element changes, some data (e.g., default configured nsai) in the UDM network element, network allowed slice information (allowed nsai) and network configured slice information (configured nsai) in an access and mobility management function (AMF) network element may change, thereby affecting the registration process of the UE.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

The terms "first" and "second," and the like, in the description and in the claims of embodiments of the present invention are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first network element and the second network element, etc. are used to distinguish different network elements, rather than to describe a particular order of the network elements.

In the description of the embodiments of the present invention, "a plurality" means two or more unless otherwise specified. For example, a plurality of elements refers to two elements or more than two elements.

The term "and/or" herein is an association relationship describing an associated object, and means that there may be three relationships, for example, a display panel and/or a backlight, which may mean: there are three cases of a display panel alone, a display panel and a backlight at the same time, and a backlight alone. The symbol "/" herein denotes a relationship that an associated object is or, e.g., input/output denotes input or output.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present relevant concepts in a concrete fashion.

The following explains some concepts and/or terms involved in the information indication method, apparatus and system provided by the embodiments of the present invention.

Network Slice Selection Assistance Information (NSSAI), which may be referred to as a network slice for short, is a set of at least one S-NSSAI (single-NSSAI). In a fifth generation mobile communication (5G) network, network resources (e.g., network elements/network logic functions) are divided into a plurality of combinations, one combination is called a slice (i.e., S-NSSAI), network elements in one combination are defined in the same Public Land Mobile Network (PLMN), and one combination at least includes two parts: an access network and a core network.

Allowed NSSAI (allowed NSSAI): after the UE is successfully registered in the registration area of the current PLMN, the allowed NSSAI may be used to indicate which slices of the current PLMN may be used by the service of the UE, for example, a Protocol Data Unit (PDU) Session (Session) may be established in the slices.

Configuring NSSAI (configured NSSAI): the slices are configured by the current PLMN (serving PLMN), but neither the UE nor the network device can determine whether the slices can provide normal services at the current location and current time of the UE, and in some scenarios, a Virtual Public Land Mobile Network (VPLMN) may send the UE to configure NSSAI.

Default configured NSSAI (default configured NSSAI): the UE is configured by a UDM of a home public land mobile network (home PLMN, HPLMN). When the serving PLMN does not provide a configuration NSSAI, registration may be requested with this default configuration NSSAI. That is, the default configuration NSSAI applies to any PLMN.

Signed NSSAI (subscribed NSSAI): NSSAI subscribed to by UE in HPLMN.

Default NSSAI (default NSSAI): one or more of The Subscribed S-NSSAIs are labeled as default S-NSSAI, also known as default configuration S-NSSAI. These default NSSAIs may be treated as allowed NSSAIs to be sent to the UE in some scenarios.

Request NSSAI (requested NSSAI): after the UE camps on a cell of a certain PLMN, when initiating registration, it may indicate to the network device which NSSAIs of the current PLMN can request services.

Reject NSSAI (rejected NSSAI): these slices may not provide normal service in a certain PLMN or a certain registration area.

The embodiment of the invention provides an information indication method, equipment and a system.A first network element can send a first configuration update message to UE according to received target information (namely information corresponding to UE in a second network element) sent by a second network element, wherein the first configuration update message comprises the target information for indicating the UE to carry out configuration update. Since the first network element sends some information in the second network element to the UE through the first configuration update message, that is, through the configuration update procedure, without specially initiating other procedures (for example, downlink non-access stratum transmission procedure), signaling overhead between devices can be reduced.

The information indication method, the equipment and the system provided by the embodiment of the invention can be applied to a communication system. The method may be specifically applied to a process in which the first network element indicates the UE to perform the configuration update through the configuration update process based on the communication system.

Since the first network element sends some information in the second network element to the UE through the first configuration update message, that is, through the configuration update procedure, without specially initiating other procedures (for example, downlink non-access stratum transmission procedure), signaling overhead between devices can be reduced.

Optionally, in this embodiment of the present invention, the first configuration update message further includes at least one of the following information, corresponding to the UE, in the first network element: an allowed NSSAI, which is sent by the first network element in case of a change in allowed NSSAI, and a configured NSSAI, which is sent by the first network element in case of a change in configured NSSAI.

And step 16, the UE sends a feedback result to the AMF network element, and the feedback result is used for indicating the UE to successfully receive which information to the AMF network element.

Step 17, the AMF network element receives and analyzes the feedback result of the UE, and if it is determined that the UE has successfully received default configured nsais and/or other information, a feedback message may be prepared to the UDM network element, where the feedback message may use an interface numm _ SDM _ Info and indicate in the feedback message: whether the UE has successfully received default configured NSSAIs and/or other information.
