Abstract
The invention provides a network slice registration method and a terminal, wherein the method comprises the following steps: selecting a first S-NSSAI with the most successful registration times in the PLMN from a history record of the S-NSSAIs stored by the terminal, wherein the history record stores at least one S-NSSAI under the PLMN and the successful registration times of the terminal to the network slice by using the S-NSSAI; configuring a first Requested NSSAI according to the first S-NSSAI; and sending a first Requested NSSAI to the target PLMN for network slice registration. Therefore, the scheme of the invention solves the problem that the time delay of the terminal registering to the 5G network is long in the prior art.
Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a network slice registration method and a terminal.
Background
The concept of slice networking is provided in the 5G protocol, and different slices are provided for different application scenes, so that different terminals can obtain targeted services. Therefore, different network slice identifications can be introduced for different scenes in the future, and users of the same type can exist in the same network slice by adding terminals into different slice groups, so that the same service type is provided. Under each Public Land Mobile Network (PLMN), the terminal registers to the network by constructing a request network slice selection assistance information (Requested nsai) and sending it to a mobile management function (AMF).
The process in the current protocol is that the terminal root configures network slice selection assistance information (Configured-NSSAI), or allows the network slice selection assistance information (Allowed-NSSAI), or a combination of both to construct a request network slice assistance information (Requested NSSAI) for registration. But the amount of single network slice selection assistance information (S-NSSAI) contained in the Requested NSSAI is not specified explicitly. And, as the protocol states, when there is an S-NSSAI that is not supported by the current AMF among the S-NSSAIs included in the Requested NSSAI sent by the terminal to the AMF, the current AMF forwards the registration signaling to one of a series of default AMFs. However, this forwarding action will result in a prolonged time for the terminal to register with the network, thereby bringing a bad experience to the user.

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 derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a network slice registration method, as shown in fig. 1, the method includes:
step 101: and selecting the first S-NSSAI with the most successful registration times in the PLMN from the history records of the S-NSSAIs stored by the terminal.
Wherein, the history record stores at least one S-NSSAI under PLMN and the number of times that the terminal successfully registers the network slice by using the S-NSSAI. In addition, if a plurality of S-NSSAIs with the largest registration success times exist in the history record, one S-NSSAI can be randomly selected as the first S-NSSAI.
Preferably, the S-NSSAIs in the history record comprise a first type S-NSSAI, and the first type S-NSSAI is a network configured S-NSSAI; the step of selecting the first S-NSSAI with the largest registration success frequency in the target PLMN from the history records of S-NSSAIs stored by the terminal comprises the following steps:
and selecting the first S-NSSAI with the largest registration success frequency in the target PLMN from the received intersection between the Configured-NSSAI and the first type S-NSSAI sent by the target PLMN after the network slice is successfully registered last time.
Preferably, the S-NSSAIs in the history record include a second type of S-NSSAI, which is an S-NSSAI allowed by the target PLMN among S-NSSAIs requested by the terminal from the target PLMN;
the step of selecting the first S-NSSAI with the largest registration success frequency in the target PLMN from the history records of S-NSSAIs stored by the terminal comprises the following steps:
and selecting the first S-NSSAI with the largest registration success frequency in the target PLMN from the received intersection between the Allowed-NSSAI and the second type S-NSSAI sent by the target PLMN after the network slice is successfully registered last time.
The S-NSSAIs in the history record comprise a first type S-NSSAI and a second type S-NSSAI, wherein the first type S-NSSAI is a network configured S-NSSAI, and the second type S-NSSAI is an S-NSSAI allowed by the target PLMN in the S-NSSAIs requested by the terminal to the target PLMN;
the step of selecting the first S-NSSAI with the largest registration success frequency in the target PLMN from the history records of S-NSSAIs stored by the terminal comprises the following steps:
determining the party with higher priority as a target class according to the preset priorities of the first class S-NSSAI and the second class S-NSSAI;
when the target category is the first-class S-NSSAI, selecting a first S-NSSAI with the largest registration success frequency in the target PLMN from the received intersection between the Configured-NSSAI and the first-class S-NSSAI sent by the target PLMN after the network slice is successfully registered for the last time;
and when the target category is the second category S-NSSAI, selecting the first S-NSSAI with the largest registration success frequency in the target PLMN from the received intersection between the Allowed-NSSAI and the second category S-NSSAI sent by the target PLMN after the network slice is successfully registered last time.
The Configured-NSSAI is an NSSAI Configured by the network for the terminal to use, and after receiving the configuration parameter, the terminal knows which S-NSSAIs are available in the network (where the NSSAI includes a plurality of S-NSSAIs, that is, the NSSAI is a set of S-NSSAIs). The network sends the Configured-NSSAI to the terminal by carrying it in a Registration Accept message (Registration Accept). The Allowed-NSSAI is the S-NSSAI Allowed by the network in the S-NSSAI requested by the terminal to the network, and the network carries the Allowed-NSSAI in Registration Accept and sends the Allowed-NSSAI to the terminal.
The first type of S-NSSAI may be stored in a first list and the second type of S-NSSAI may be stored in a second list, e.g., the first list may be named mConfigured-NSSAI and the second list may be named mallewed-NSSAI. Therefore, according to the Configured-NSSAI sent by the target PLMN and received after the terminal successfully registers the network slice for the last time, the S-NSSAI with the largest registration success number can be selected from the mConfigured-NSSAI; or selecting the S-NSSAI with the largest registration success frequency from the mAllowed-NSSAI according to the received Allowed-NSSAI sent by the target PLMN after the terminal successfully registers the network slice last time.
Wherein, it should be noted that mConfigured-NSSAI is different from Configured-NSSAI; similarly, mAllowed-NSSAI is different from Allowed-NSSAI. Moreover, the existing protocol provides that the maximum number of S-NSSAIs in Configured-NSSAI is 16, the maximum number of Allowed-NSSAIs is 8, Configured-NSSAI and Allowed-NSSAI stored by the terminal are replaced when the next configuration update occurs, but the update of mConconfigured-NSSAI and mAllowed-NSSAI is that S-NSSAI is added to mConconfigured-NSSAI according to Configured-NSSAI sent by the network after the terminal successfully registers to the network slice, or S-NSSAI is added to mAllowed-NSSAI according to Allowed-NSSAI sent by the network.
In addition, according to the Configured-NSSAI sent by the target PLMN after the network slice is successfully registered last time by the terminal, the S-NSSAI with the largest registration success frequency is selected from the mConconfigured-NSSAI, and the probability of successfully registering the network slice according to the selected S-NSSAI is further increased.
Similarly, according to the received Allowed-NSSAI sent by the target PLMN after the terminal successfully registers the network slice last time, the S-NSSAI with the largest registration success frequency is selected from the mAllowed-NSSAI, and the probability of successfully registering the network slice according to the selected S-NSSAI is further increased.
Step 102: configuring a first Requested NSSAI according to the first S-NSSAI.
That is, in the embodiment of the present invention, a Requested NSSAI is formed according to the first S-NSSAI selected from the history. And for other parameters carried in the Requested NSSAI, the normal configuration is specified according to the existing protocol.
The AMF judges whether the current AMF can serve the terminal according to the Requested NSSAI, so that when the number of S-NSSAIs in the Requested NSSAI is minimum and the S-NSSAI with the maximum registration success frequency is obtained, the possibility that the terminal can successfully register in the current AMF is extremely high, the time that the AMF forwards the Requested NSSAI registered by the terminal to the default AMF for judgment is saved, and the terminal can be registered in the network more quickly.
Step 103: and sending the first Requested NSSAI to a target PLMN for network slice registration.
Preferably, after sending the first Requested NSSAI to the target PLMN for network slice registration, the method further includes: after the network slice registration is successfully completed, the number of times that the terminal successfully registers the network slice by using the first S-NSSAI is updated in the history record, so that the history record stored in the terminal can be updated at any time along with the network registration process of the terminal, and the terminal is convenient to use during subsequent network registration.
Preferably, after sending the first Requested NSSAI to the target PLMN for network slice registration, the method further includes:
receiving Configured-NSSAI sent by the target PLMN after the terminal successfully registers the network slice;
updating the S-NSSAI in the history record according to the Configured-NSSAI;
or
Receiving Allowed-NSSAI sent by the target PLMN after the terminal successfully registers the network slice;
and updating the S-NSSAI in the history record according to the Allowed-NSSAI.
After the terminal successfully registers the network slice, the network configures NSSAI for the terminal, and the terminal receives Configured-NSSAI; alternatively, after the terminal successfully registers the network slice, the terminal requests NSSAI from the network, and then the network returns Allowed NSSAI, and the terminal receives Allowed-NSSAI.
In addition, the Configured-NSSAI includes a plurality of S-NSSAIs, and when the S-NSSAI in the history is updated according to the Configured-NSSAI, the S-NSSAI that exists in the Configured-NSSAI but does not exist in the history needs to be added to the history, so that the history stored in the terminal can be updated at any time along with the network registration process of the terminal, and further, the history can be used in subsequent network registration.
Similarly, the Allowed-NSSAI includes a plurality of S-NSSAIs, and when the S-NSSAI in the history is updated according to the Allowed-NSSAI, the S-NSSAI that exists in the Allowed-NSSAI but does not exist in the history needs to be added to the history, so that the history stored in the terminal can be updated at any time along with the network registration process of the terminal, and further, the history can be used in subsequent network registration.
Preferably, the method further comprises: and when the target PLMN is updated, deleting the history record, thereby ensuring the validity of the history record.
Preferably, after successfully completing the network slice registration, the method further comprises:
acquiring a second S-NSSAI of a second network slice registered under the target PLMN;
configuring a second Requested NSSAI according to the second S-NSSAI;
and sending the second Requested NSSAI to the target PLMN for network slice registration.
In the embodiment of the present invention, since the registration of the network slice is completed by using the S-NSSAI with the largest number of successful registrations selected from the history record stored in the terminal in advance, so that the terminal is already in the networking state, at this time, if the terminal is registered to another network slice again, even if there is an S-NSSAI that is not supported by the current AMF in the S-NSSAIs of the network slices, the network delay is not caused.
That is, the embodiment of the present invention is equivalent to that when the network slice is registered at startup, a simple registration is performed by using the S-NSSAI with the largest number of successful registrations, and then the registration is performed in the required network slice, thereby reducing the time required by the user to stay in the network.
In summary, in the embodiments of the present invention, the S-NSSAI with the largest number of successful registration times under the target PLMN is selected from the history of S-NSSAIs stored in the terminal, and the network slice is registered according to the selected S-NSSAI. The selected S-NSSAI is the S-NSSAI with the largest network switching times, so that when the terminal performs network slice registration according to the selected S-NSSAI, the probability of successful registration is increased, the time required by network residence is shortened, and the time delay of network registration is shortened.
