specific Embodiment 1

[0038] In the LTE system, UE1 resides in cell 1 under the jurisdiction of base station 1, and is in an idle state. A valid EAB is configured in the USIM card of UE1, which can be set to True in the EAB configuration. In addition, the USIM card of UE1 indicates that the access class (Access Class) of the UE is 11.

[0039] When UE1 needs to initiate a delay tolerant (Delay Tolerant) service or a low priority (Low Priority) service, the non-Access Stratus (NAS) layer of UE1 sends the establishment reason to the AS layer of UE1 ( Establishment Cause) is the cause of delay tolerance or low priority. The procedure for implementing access decision at the AS layer of UE1 is as follows: figure 2 Shown:

[0040] Step 101: UE1 judges whether the waiting time timer (T302) or the access restriction timer set for delay tolerance or low-priority services is running. If it is running, UE1 judges that access to the current cell is prohibited; If the two timers are not running, step 102 is execu...

specific Embodiment 2

[0050] In the LTE system, UE2 resides in cell 2 under the jurisdiction of base station 2 and is in an idle state. A valid EAB is configured in the USIM card of UE2. In addition, the USIM card of UE2 indicates that the access class of the UE is 12, that is, the Access Class is 12.

[0051] When UE2 needs to initiate a delay tolerant (Delay Tolerant) service or a low priority (Low Priority) service, the NAS layer (non-Access Stratus, non-access layer) of UE2 sends the establishment cause (Establishment Cause) to the AS layer of UE1. ) Is the reason for delay tolerance or low priority. The procedure of UE2's AS layer to implement access decision is as follows image 3 Shown:

[0052] Step 201: UE2 judges whether the waiting time timer (T302) or the access restriction timer set for delay tolerance or low-priority services is running. If it is running, UE2 judges that access to the current cell is prohibited (Consider access to the cell as barred); if the two timers are not running, ...

specific Embodiment 3

[0061] In the LTE system, the UE3 resides in the cell 3 under the jurisdiction of the base station 3 and is in an idle state. A valid EAB is configured in the USIM card of UE3. In addition, the USIM card of UE3 indicates that the access class of the UE is 13, that is, the Access Class is 13.

[0062] When UE3 needs to initiate a delay tolerant (Delay Tolerant) service or a low priority (LowPriority) service, the NAS layer (non-Access Stratus, non-access layer) of UE3 finds that UE3 has a valid access level of AC 13. Therefore, the establishment reason sent by the NAS layer of UE3 to the AS layer of UE3 is the data service (MO-Data) initiated by the user or the signaling service (MO-Signalling) initiated by the user. After receiving the reason for the establishment of the new service, the NAS layer of UE3 implements an access decision based on the corresponding access restriction parameters in the system message to determine whether the UE can initiate random access and establish ...

Abstract

The invention discloses a method for executing access barring and user equipment. The method comprises the step of carrying out cell access judgement according to access class limit parameters corresponding to a data service initiated by user equipment at a common level in a system message, or according to access class limit parameters corresponding to a signalling service initiated by the user equipment at the common level in the system message or according to extended access class parameters in the system message when the user equipment which is applicable to extended access and is at a non-common access level initiates a delay tolerant service. According to he scheme is applicable to the extended access barred (EAB) user equipment at the non-common access level, a network side can carry out access barring on the user equipment, and the problem that the access judgement is inaccurate when the user equipment accesses a network can be solved.

Description

Technical field [0001] The present invention relates to mobile communication technology, and in particular to a method and user equipment for performing access control. Background technique [0002] User equipment (User Equipment, UE) needs to perform access control when accessing the network 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) and Long Term Evolution (LTE), user equipment can be divided into 16 access classes (Access Class, AC), among which, AC0-9 It is a common level and is randomly assigned to terminals; AC 10 means emergency calls and will not be assigned to terminals; AC 11 is used for network operations; AC 12 is a security service; AC 13 is a public service category, such as water and gas suppliers; AC 14 means Emergency business; AC 15 represents operator staff. A terminal can be configured to one level...
