Embodiment Construction

[0019] In order to make the purpose, technical solutions and beneficial effects of the embodiments of the invention more clear, the specific implementation manners of the embodiments of the invention will be described in detail below in conjunction with the accompanying drawings.

[0020] An embodiment of the present invention provides a method for restricting access types. In an LTE system, when a UE in an idle state receives the SI sent by the system, if the UE's AC is between 0 and 9, the UE's AC The access stratum (Access Stratum, AS) calculates a random number. If the random number is compared with the ACB percentage contained in the SI and it is found that access is impossible, the AS layer notifies the non-access stratum (Non-Access Stratum) through an inter-layer primitive. Access Stratum, NAS), this primitive includes a cause value, and may also include a restricted time, which instructs the UE to wait for the restricted time before attempting to access, and the settin...

Abstract

The invention discloses a method for barring access class. The method comprises the following steps that: user equipment UE receives system information SI transmitted by a network side, wherein the SI contains Access Class Barring ACB information; and the UE calculates random number according to the ACB information, when the UE cannot be accessed to a network according to the random number, an access stratum AS of the UE transmits interlayer primitive to a non-access stratum NAS, and the interlayer primitive contains a cause value. The invention also discloses user equipment, which comprises a receiving unit and an executing unit. By the method and the device provided by the embodiment of the invention, barring of the network on the access class of a user can be fairer, and the sensitivity of the user can be improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for restricting access types. Background technique [0002] The access type (Access Class, AC) is information stored in the Subscriber Identification Module (SIM) of the User Equipment (User Equipment, UE). Each mobile phone with a SIM card has an AC. Types can be divided into 16 levels (0 to 15). In 2G and 3G networks, before initiating random access each time, the UE checks the provisions of the cell system information to determine whether its AC is allowed to access, and if not, it waits. Only when the AC information in the system information (System Information, SI) changes, and the changed AC information allows its own AC to access, the UE can initiate a service. Specifically, in a 3G network, the Universal Mobile Telecommunications System (UMTS) adopts an individual designation method, that is, uses SI to designate certain ACs as restricted states, so that UEs with thes...
