determining whether system information comprises the extended access barring parameters relevant with the category corresponding to the UE;

if not comprising, determining whether the system information comprises extended access barring parameters applicable for the UE;

if the determining result of the determining whether system information comprises the extended access barring parameters relevant with the category corresponding to the UE is comprising, or the determining result of the determining whether the system information comprises extended access barring parameters applicable for the UE is comprising, then applying the extended access barring parameters to determine whether the UE can access the current cell;

if the determining result of the determining whether the system information comprises extended access barring parameters applicable for the UE is not comprising, then determining that the UE can access the current cell.

3 . A method of claim 2 , wherein, the determining whether the system information comprises extended access barring parameters applicable for the UE comprises:

determining whether the system information comprises the extended access barring parameters covering the category corresponding to the UE.

4 . A method of claim 1 , wherein, the method comprises:

an access stratus receiving a service request from an upper stratus;

when the determining whether the UE can access the current cell based on the extended access barring, according to the extended access barring parameters of the UE determines that the UE can not access the current cell, the method comprises:

informing the upper stratus of the reason of refusing access based on the extended access barring.

5 . A method of claim 1 , wherein, when the determining result of the determining whether the UE has a special access level which is valid and not barred is not having, continuing the determining whether a system information block comprises extended access barring parameters of the UE, or determining whether the UE can access the current cell based on the extended access barring, according to the extended access barring parameters of the UE, or applying an access class barred (ACB) to determine whether the UE can access the current cell;

when the determining result of the determining whether a system information block comprises extended access barring parameters of the UE, step d is not having, continuing to apply the access class barred to determine whether the UE can access the current cell;

after the determining whether the UE can access the current cell based on the extended access barring, according to the extended access barring parameters of the UE determines the UE can access the current cell based on the extended access barring, continuing to apply the access class barred to determine whether the UE can access the current cell.

6 . A method of claim 4 , wherein, the method comprises:

applying an access class barred, and determining whether the UE can access the current cell based on the access class barred;

when determining that the UE can access, continuing the determining whether a system information block comprises extended access barring parameters of the UE;

when determining that the UE can not access, informing the upper stratus of the reason of refusing access based on the access class barred.

7 . A method of claim 4 , wherein, the upper stratus of the UE decides a minimum time for which re-initiating the service request needs to wait, according to the reason of refusing access,

wherein, the minimum time corresponding to refusing access based on the extended access barring is not less than the minimum time corresponding to refusing access based on the access class barred.

8 . A method of claim 1 , wherein, the method comprises the following steps before the determining whether the UE has a special access level which is valid and not barred—when having, determining that the UE can access a current cell:

determining whether an access timer is in a timing state;

when the access timer is not in the timing state, implementing the determining whether the UE has a special access level which is valid and not barred—when having, determining that the UE can access a current cell; otherwise, determining that the UE can not access the current cell;

wherein, the access timer comprises at least one timer of the following:

an waiting time timer;

an access barring timer, configured for delay tolerance services;

an access barring timer, configured for UE-initiated data services;

an access barring timer, configured for UE-initiated signaling services;

9 . A method of claim 1 , wherein, the UE comprises the UE applicable for the extended access barring, and the service request comprises delay tolerance services.

10 . An access control module used in a UE, wherein, the access control module comprises the following components:

a first determining unit which is used for determining whether the UE has a special access level which is valid and not barred: when having, determining that the UE can access a current cell;

a second determining unit which is used for determining whether a system information block comprises extended access barring parameters of the UE;

a third determining unit which is used for determining whether the UE can access the current cell based on extended access barring, according to the extended access barring parameters of the UE, in case that the second determining unit determines comprising.

11 . The access control module of claim 10 , wherein, the third determining unit is further used for informing an upper stratus of the reason of refusing access based on the extended access barring, when the third determining unit determines that the UE can not access.

12 . The access control module of claim 10 , wherein, the access control module still comprises a fourth determining unit, which is used for applying an access class barred to determine whether the UE can access the current cell, and the fourth determining unit operates when any one of the following cases occurs:

the determining result of the first determining unit is not having;

the determining result of the second determining unit is not comprising; and

the third determining unit determines the UE can access the current cell based on the extended access barring.

13 . The access control module of claim 10 , wherein, the access control module still comprises a fourth determining unit, which is used for applying an access class barred to determine whether the UE can access the current cell;

when the fourth determining unit determines the UE can access, the second and third determining units continue operating; the fourth determining unit is used for informing an upper stratus of the reason of refusing access based on the access class barred, when determining that the UE can not access.

14 . The access control module of claim 11 ,

wherein, the access control module decides a minimum time for which re-initiating the service request needs to wait, according to the reason of refusing access,

wherein, the minimum time corresponding to refusing access based on the extended access barring is not less than the minimum time corresponding to refusing access based on the access class barred.

15 . A UE, wherein, the UE comprises an access control module according to claim 10 .
