8. The method according to claim 6 ,

wherein the plurality of SIBs comprises a first SIB and a second SIB,

wherein the first SIB comprises the access control information list; and

the second SIB comprises the mapping relationship.

9. The method according to claim 8 , wherein the first SIB further comprises the grouping information about the access control group, or the second SIB further comprises the grouping information about the access control group.

10. A method for transmitting access control information, comprising:

acquiring an access control information list and a mapping relationship between a group of access control parameters in the access control information list and an access control group that are transmitted from a network side device; and

determining access control parameters of an access control group in accordance with the access control information list and the mapping relationship,

wherein the mapping relationship is recorded as:

a correspondence between an access control group identity and a list index number; or

a correspondence between a list index number and an access control group identity or an identity list,

wherein the list index number is a sequence number of the group of access control parameters in the access control information list.

wherein the mapping relationship is recorded as:

a correspondence between an access control group identity and a list index number; or

a correspondence between a list index number and an access control group identity or an identity list,

wherein the list index number is a sequence number of the group of access control parameters in the access control information list.

13. The network side device according to claim 12 , wherein the access control parameters comprise at least one of a control factor parameter, a control timer parameter, and a high-priority access identity state parameter.

14. The network side device according to claim 12 , wherein the access control group is an AC in a PLMN, or a first AC group based on the PLMN, or a second AC group based on all PLMNs.
