Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

The network slice is one of the key characteristics of 5G, and operators meet the requirements of different service scenes of 5G through the network slice. A network slice is an end-to-end logical network that provides specific network capabilities and network characteristics. By using resource isolation technologies such as virtualization, operators can deploy multiple network slices on the same physical facility as required, so that flexible and various service scenes are met. The NSSAI consists of a series of Single Network Slice Selection Assistance Information (S-NSSAI). The end-to-end network slice is identified by an S-NSSAI, and slice resources of different domains can be associated through the slice identification S-NSSAI to form an independent logic slice network.

However, in the course of making the creation, the inventors found that: in the related art, it is only clear that the AMF may indicate whether and when the terminal carries the NSSAI at the time of the Access layer Connection Establishment through a Registration Accept (Registration Accept) message (please refer to fig. 2) sent to the terminal during the Registration procedure to carry an Access Stratum Connection Establishment NSSAI Inclusion Mode parameter. The access layer connection establishment NSSAI comprises a mode parameter that is a 2-bit value representing 4 modes.

Fig. 3 is a schematic diagram of a network slice, where slice 2 and slice 3 use different AMFs. Fig. 4 is a schematic diagram of another network slice, in the network slice scenario shown in fig. 4, a network has three slices (C/B/a), subscription data of the three slices are stored respectively, when a terminal first accesses the network, the terminal does not carry NSSAI in consideration of privacy, a base station (gNB) randomly or accesses the terminal to a default AMF, and then two situations occur:

1. if the AMF can access the UDM of the terminal user, and can pass authentication, and the registration is likely to be successful, the AMF will return a registration acceptance message to the terminal, and the registration acceptance message carries the access layer connection establishment NSSAI containing mode parameters. When the terminal accesses the network next time, the NSSAI can be carried according to the indication of the parameter, and the base station selects a proper AMF for the terminal according to the NSSAI;

2. if the AMF cannot access the UDM of the terminal user, the authentication cannot be passed, the registration cannot be successful, and the AMF cannot reply a registration acceptance message to the terminal. Consequently, the AMF cannot bring the NSSAI-containing mode parameter of the access layer connection establishment to the terminal. When the terminal accesses next time, the terminal will continue to try the above procedure, and it is likely that one AMF is randomly selected, and even the default AMF is accessed, it is likely that the registration is not successful. Therefore, the terminal cannot select the correct AMF for a long time, so that the network cannot be accessed all the time, the influence on the user experience is very large, and the user can display the 5G signal in a visual sense and cannot access the network all the time.

In view of the above problems, the present invention provides the following embodiments.

Referring to fig. 5, fig. 5 is a flowchart illustrating a method for indicating NSSAI carrying according to an embodiment of the present invention, where the method is applied to a network side device, and includes the following steps:

step 51: the network side equipment sends indication information to the terminal under the condition that the terminal registration fails;

Specifically, the indication information may be an access stratum connection establishment NSSAI inclusion mode parameter. The network side device may be an AMF.

In the embodiment of the invention, the time for the network side equipment to send the indication information for indicating whether the terminal carries NSSAI when the access layer connection is established or not is increased, so that the access time delay of the terminal is shortened, and the flexibility and the real-time property of sending the indication information are improved. Specifically, the network side device may send, to the terminal that has failed in registration, indication information indicating whether or not and when the terminal carries NSSAI when establishing access layer connection, so that the terminal may carry NSSAI according to the indication information when accessing next time, and the base station may select a suitable AMF according to NSSAI, thereby avoiding a problem that the terminal cannot always access the network because the terminal does not carry NSSAI all the time, and the base station always randomly selects an AMF for the terminal or selects a default AMF, so that the terminal can quickly access the correct network, thereby shortening terminal access delay, and improving user experience. In addition, under the condition that the terminal registration fails, the network side equipment can also send the indication information to the terminal, so that the flexibility and the real-time performance of the configuration or the modification of the indication information are improved.

The above method of indicating NSSAI carrying is exemplified below.

In an optional specific embodiment, the step of sending the indication information to the terminal when the terminal fails to register includes:

In the embodiment of the present invention, the indication information is carried by the registration rejection message. Specifically, the AMF side may configure an operator policy locally, and send an access layer connection setup NSSAI inclusion mode parameter to the terminal in a registration reject message for the terminal that fails to register (fails to access). Referring to fig. 6, the main flow of the terminal registration failure includes:

1) The terminal initiates a Registration Request and sends AN RRC access message to the access network, which may include access network parameters (AN parameters) and a Registration Request (Registration Request) message.

2) The access network selects the AMF randomly or selects a default AMF.

3) The access network sends a next generation application protocol Initial terminal Message (NGAP Initial UE Message) including a registration request Message to the selected AMF.

4) Corresponding to steps 8 and 9 in fig. 6, AMF initiates AUSF selection, and AMF and AUSF perform terminal authentication.

5) Corresponding to step 9 in fig. 6, amf does not find the UDM corresponding to the terminal.

6) Corresponding to step 10 in fig. 6, the amf sends a Registration Reject (Registration Reject) message to the terminal, carrying the access layer connection establishment NSSAI including the mode parameter.

In other alternative embodiments, the indication information may not be carried in the registration rejection message, but may be carried by another message. Further optionally, the other message may be a newly added message, that is, a newly added message flow is added to send the indication information to the terminal.

Referring to fig. 7, fig. 7 is a flowchart illustrating a method for indicating NSSAI carrying according to a second embodiment of the present invention, where the method is applied to a network side device, and includes the following steps:

step 71: the network side equipment sends indication information to a terminal under the condition that the terminal has access to a network;

In the related art, once the terminal accesses the network, the network has no opportunity to modify the access layer connection establishment NSSAI inclusion mode parameter, for example, the modification operation of the network manager to the access layer connection establishment NSSAI inclusion mode parameter of the terminal having accessed the network will not be effective. That is, in the related art, once the terminal accesses the network, there is no opportunity to configure or modify whether or not the terminal carries NSSAI at the next access and when the terminal carries NSSAI at the time of establishing the access layer connection. In order to solve the technical problem, the embodiment of the invention provides the technical scheme.

In the embodiment of the invention, the time for the network side equipment to send the indication information for indicating whether the terminal carries NSSAI when the access layer connection is established or not is increased, so that the access time delay of the terminal is shortened, and the flexibility and the real-time property of sending the indication information are improved. Specifically, under the condition that the terminal has access to the network, the network side device can also send the indication information for indicating whether or not and when the terminal carries the NSSAI when establishing the access layer connection to the terminal, so that network operation and maintenance personnel can configure or modify the indication information for the terminal at any time, thereby improving the flexibility and the real-time property. In addition, the problem of increased access delay caused by not carrying NSSAI when the terminal accesses the network next time can be solved.

The above-described method for indicating NSSAI carriage is exemplified below.

Optionally, the indication information may be carried by a UE parameter configuration request (UE parameter configuration request) message, or may be carried by another Non-Access Stratum (NAS) message.

Specifically, in the embodiment of the present invention, the indication information may be sent to the terminal by adding a terminal parameter configuration flow and a message, so as to configure or modify the indication information more flexibly and in real time.

In an optional specific embodiment, if the terminal is in an idle state, the step of sending the indication information to the terminal in the case that the terminal has accessed the network includes:

sending a paging message to the terminal so that the terminal triggers a service request flow and enters a connection state;

and receiving feedback information sent by the terminal, wherein the feedback information is used for indicating that the terminal has accepted the indication information. Specifically, the feedback information may be a terminal parameter configuration accept (UE parameter configuration accept) message or carried by the terminal parameter configuration accept message.

Specifically, referring to fig. 8, a specific process of sending the indication information to the terminal includes:

and 1, when the AMF needs to send the indication information to the terminal, if the terminal is found to be in an idle state, triggering a paging process and sending a paging message to the base station. Specifically, the AMF may trigger to send the indication information to the terminal according to an Operation, administration and Maintenance (OAM) action of a network Operation and Maintenance worker.

2. The base station initiates paging to the terminal.

3. The terminal initiates a service request (service request) process, establishes a connection with the network, and enters a connected state.

And 4, the AMF sends a terminal parameter configuration request message to the terminal (through the base station), wherein the message carries the indication information.

5. The terminal transmits a terminal parameter configuration acceptance message to the AMF (via the base station).

If the terminal is already in the connected state, the first three steps of the process are omitted.

Referring to fig. 9, fig. 9 is a schematic flowchart of a method for indicating NSSAI carrying according to a third embodiment of the present invention, where the method is applied to a network side device, and includes the following steps:

step 91: the network side equipment sends indication information to the terminal under the condition that the terminal registration fails;

and step 92: the network side equipment sends indication information to a terminal under the condition that the terminal has access to a network;

The execution order of the

above steps

91 and 92 is not limited. The terminal in step 91 and the terminal in step 92 may be the same terminal or different terminals.

That is to say, the network side device may send the indication information to the terminal that has failed to register, or may send the indication information to the terminal that has accessed the network.

Specifically, the indication information may be an access layer connection establishment NSSAI including mode parameter. The network side device may be an AMF.

In the embodiment of the invention, the time for the network side equipment to send the indication information for indicating whether the terminal carries NSSAI when the access layer connection is established or not is increased, so that the access time delay of the terminal is shortened, and the flexibility and the real-time property of sending the indication information are improved.

Specifically, the network side device may send, to the terminal that fails to register, indication information indicating whether or not and when the terminal carries the NSSAI when establishing the access layer connection. Under the condition that the terminal has access to the network, the network side device can also send indication information to the terminal, wherein the indication information is used for indicating whether or not and when the terminal carries NSSAI when the access layer connection is established. Therefore, the network side device can configure or modify the indication information for the terminal regardless of whether the terminal has access to the network and regardless of whether the terminal is in an idle state or a connected state.

The above-described method for indicating NSSAI carriage is exemplified below.

The embodiment of the present invention includes two cases in the first embodiment and the second embodiment, and please refer to the first embodiment and the second embodiment in detail, which will not be described herein again.

In addition, under the condition that the terminal registration fails, the indication information sent by the network side equipment can be received, so that the flexibility and the real-time performance of the configuration or modification of the indication information are improved.
