Embodiment 1

[0052] In UMTS, UE1 resides in a cell 1 under the jurisdiction of a radio network controller (Radio Network Controller, RNC), and is in an idle state. A valid EAB is configured in the USIM card of UE1, which may be that the EAB configuration is set to True. In addition, the USIM card of UE1 indicates that the access class of the UE is 2, that is, the Access Class is 2.

[0053] When UE1 needs to initiate a service request, UE1 needs to judge whether it can access and initiate a service request according to the EAB parameters and ACB parameters broadcast by cell 1. At this time, the EAB parameter broadcast in cell 1 is enumerated, and it is set to not barred for AC 2. At the same time, the ACB parameter broadcast in cell 1 is also enumerated, and it is not barred for AC 2. After checking the EAB parameter and the ACB parameter, UE1 learns that it can access the network, and UE1 enters the process of initiating random access.

[0054] In the existing UMTS, user equipments of di...

Embodiment 2

[0067] In UMTS, UE2 resides in a cell 2 under the jurisdiction of a Radio Network Controller (RNC) 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 3, that is, the Access Class is 3.

[0068] When UE2 needs to initiate a service request, UE2 needs to judge whether it can access and initiate the service request according to the EAB parameter broadcast by cell 2. At this time, the EAB parameter broadcast in the cell 2 is the access scale factor (ac-BarringFactor), and the scale factor is equal to 0.7. UE2 generates a random number uniformly distributed between 0 and 1. If the random number is lower than 0.7, UE2 can initiate a random access procedure; if the generated random number is higher than or equal to 0.7, UE2 cannot immediately initiate a random access procedure . In this embodiment, the random number generated by UE2 is lower than 0.7, so UE2 enters the process o...

Abstract

The invention discloses an access control method comprising the following steps that: user equipment (UE) suitable for extended access control block (EAB) initiates a random access by use of a random access resource mapped corresponding to a self-mapped access service class (ASC), specifically, the UE suitable for extended EAB obtains the self-mapped ASC according to the system information of the network side, or obtains the self-mapped ASC according to a protocol based predetermined configuration. The invention correspondingly discloses an access control system and the UE. According to the invention, the random access process of the UE suitable for the EAB is controlled, and the high impact to the UE unsuitable for the EAB caused by the access of a large amount of UE suitable for the EAB, is avoided.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to an access control method, system and UE. Background technique [0002] User equipment (User Equipment, UE) needs to 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 the Universal Mobile Telecommunications System (UMTS), user equipment can be divided into 16 access classes (Access Class, AC), among which, AC 0 to 9 belong to ordinary classes and are randomly assigned to terminals; AC 10 means Emergency calls will not be assigned 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 is for emergency services; AC 15 is for operator staff. A terminal can be configured as one level in AC0-9 and one...
