Abstract

This application discloses a method and an apparatus for a terminal to access a network, a device, and a readable storage medium. The method includes: in a case that an event corresponding to a MINT function occurs in a first network, performing access control on an access request, triggered by the MINT function, for accessing a second network.

First claim

What is claimed is:

1 . A method for a terminal to access a network, applied to a terminal, the method comprising:
when an event corresponding to a minimization of service interruption MINT function occurs in a first network, performing access control on an access request, triggered by the MINT function, for accessing a second network, wherein performing access control on the access request, triggered by the MINT function, for accessing the second network comprises:
determining, according to first information, whether the second network allows the access request of the terminal that is triggered by the MINT function to access the second network, wherein the first information comprises access control information of the second network that is related to the MINT function, and the access control information comprises: an access identity and an access probability corresponding to the access identity;
wherein determining, according to the first information, whether the second network allows the access request of the terminal that is triggered by the MINT function to access the second network comprises:
determining the access identity is indicative of that the terminal is configured with the MINT function; and
determining, according to a random number generated by the terminal and the access probability, whether the access request of the terminal that is triggered by the MINT function is allowed to access the second network.

2 . The method according to claim 1 , wherein the first information further comprises a configuration of the terminal that is related to the MINT function.

3 . The method according to claim 2 , wherein the determining, according to first information, whether the second network allows the access request of the terminal that is triggered by the MINT function to access the second network further comprises:
determining, according to an access identity selected by the terminal that corresponds to the MINT function and a received access identity corresponding to the second network supporting the MINT function, whether the second network allows the access request of the terminal that is triggered by the MINT function to access the second network.

4 . The method according to claim 3 , further comprising:
determining whether the second network supports the MINT function; and if the second network supports the MINT function, selecting, upon an access attempt in the second network, the access identity corresponding to the second network supporting the MINT function.

5 . The method according to claim 4 , wherein the determining whether the second network supports the MINT function comprises:
obtaining a function list supported by the second network; and determining whether the second network supports the MINT function according to the function list supported by the second network.

6 . The method according to claim 4 , wherein a universal subscriber identity module or a non-volatile memory of the terminal stores a first parameter, wherein the first parameter indicates the access identity corresponding to the MINT function.

7 . The method according to claim 3 , further comprising: obtaining an operator-defined access category corresponding to the MINT function through the first network or second network.

8 . The method according to claim 1 , further comprising:
initiating the access request to the second network if the second network allows the terminal to access; or reattempting to access the second network if the second network currently does not allow the terminal to access.

9 . The method according to claim 8 , wherein the reattempting to access the second network comprises:
determining an access barring condition according to the access control information of the second network; starting a timer according to the access barring condition; and reattempting to access the second network after the timer expires.

10 . The method according to claim 1 , further comprising: receiving the access control information of the second network that is related to the MINT function.

11 . The method according to claim 1 , wherein the access identity is an access identity corresponding to the MINT function of the second network; and
the access control information further comprises one or more of the following: an access category corresponding to the second network supporting the MINT function; an unforbidden access request of a first category, wherein the access request of a first category is triggered by the MINT function; an unforbidden access request of a second category, wherein the access request of a second category is triggered by a user of a specific network due to the MINT function; a delayed access request of a third category, wherein the access request of a third category is triggered by the MINT function or a user of a specific network due to the MINT function; or an access-delayed time.

12 . A method for a terminal to access a network, applied to a network side device, the method comprising:
sending access control information of a second network that is related to a MINT function to a terminal, wherein the access control information of the second network that is related to the MINT function and/or a configuration of the terminal that is related to the MINT function is used for assisting the terminal in: when an event corresponding to the MINT function occurs in a first network, performing access control on an access request, triggered by the MINT function, for accessing the second network, wherein the access control information comprises an access identity and an access probability corresponding to the access identity; the access identity is indicative of that the terminal is configured with the MINT function; and the access control information is used for assisting the terminal in: determining, according to a random number generated by the terminal and the access probability, whether the access request of the terminal that is triggered by the MINT function is allowed to access the second network.

13 . The method according to claim 12 , wherein the access identity is an access identity corresponding to the MINT function of the second network; and the access control information further comprises one or more of the following:
an access category corresponding to the second network supporting the MINT function; an unforbidden access request of a first category, wherein the access request of a first category is triggered by the MINT function; an unforbidden access request of a second category, wherein the access request of a second category is triggered by a user of a specific network due to the MINT function; a delayed access request of a third category, wherein the access request of a third category is triggered by the MINT function or a user of a specific network due to the MINT function; or an access-delayed time.

14 . A terminal, comprising:
at least one hardware processor, a memory, and a program stored in the memory and executable by the at least one hardware processor, wherein the program, when executed by the at least one hardware processor, directs the terminal to implement: when an event corresponding to a minimization of service interruption MINT function occurs in a first network, performing access control on an access request, triggered by the MINT function, for accessing a second network, wherein performing access control on the access request, triggered by the MINT function, for accessing the second network comprises:
determining, according to first information, whether the second network allows the access request of the terminal that is triggered by the MIN
