Problems solved by technology

However, there is no ready-made solution for the specific flow of user equipment performing access control, because the existing method of performing access control based on ACB does not need to consider factors such as the access type of the user equipment and the handling of the reasons for access failure. Existing access control schemes cannot be applied to schemes that perform access control based on EAB

specific Embodiment 1

[0052] In the LTE system, the UE is in an idle state. A valid EAB is configured in the USIM card of the UE, which may be that the EAB configuration is set to True. In addition, the USIM card of the UE indicates that the access class (Access Class) of the UE is 8 and 11.

[0053] When the UE needs to initiate a delay tolerant (Delay Tolerant) service or a low priority (LowPriority) service, the non-access stratum NAS (non-Access Stratus, NAS for short) layer of the UE sends the establishment reason ( Establishment Cause) is the cause of delay tolerance or low priority. The AS layer of the UE implements the access decision process as follows: figure 1 Shown:

[0054] Step 101: the AS of the UE receives a service request from its upper layer (NAS), and the reason for establishing the service is delay tolerance.

[0055] Step 102: The UE judges whether the waiting time timer (T302) is running, if it is running, the UE judges that access to the current cell is prohibited (Consid...

specific Embodiment 2

[0082] In an LTE system, a UE resides in a cell under the jurisdiction of a base station and is in an idle state. A valid EAB is configured in the USIM card of the UE. In addition, the USIM card of the UE indicates that the access class of the UE is 5, that is, the Access Class is 5.

[0083] When the UE needs to initiate a delay tolerant (Delay Tolerant) service, the NAS layer of the UE sends the establishment reason to the AS layer of the UE as a delay tolerant reason. The AS layer of the UE implements the access decision process as follows: image 3 Shown:

[0084] Step 201: the AS of the UE receives a service request from its upper layer (NAS), and the reason for establishing the service is delay tolerance.

[0085] Step 202: The UE judges whether the waiting time timer (T302) or the access restriction timer (T303) set for the data service initiated by the user is running. If it is running, the UE judges that accessing the current cell is prohibited (consider access to ...

Abstract

An expanding access control embedded array block (EAB) is not utilized for access control in the prior art. The invention provides a method of access control, a module and a user device. The method includes the flowing steps that b. whether the user device has effective and permitted special access grades (104 and 105) is judged, and when the special access grades (104 and 105) exist, current areas capable of being accessed are judged; d. whether a system message comprises the expand access control EVB parameters (103) of the user device is judged, when the expand access control EVB parameters (103) are comprised; and e. according to the expand access control EVB parameters (103) of the user device, whether access current areas (106-110) are controlled based on expanding access is judged. The invention provides a method controlling the EAB to conduct access based on expanding access.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method for performing access control and user equipment. Background technique [0002] User Equipment (UE) must perform access control when accessing the network, which is used to determine whether the UE can initiate a service request, and avoid causing network-side overload such as random access overload or signaling overload. In Universal Mobile Telecommunications System (UMTS for short) and Long Term Evolution (LTE for short), user equipment can be divided into 16 access classes (Access Class, AC), among which, AC 0~ 9 belongs to the general level and is randomly allocated to terminals; AC 10 means emergency calls and will not be allocated to terminals; AC 11 is used for network operations; AC 12 is for security services; AC 13 is for public service categories, such as water and gas suppliers; AC 14 Indicates emergency business; AC 15 indicates operator staff. A ...
