Problems solved by technology

[0004] However, in the prior art, when the UE reselects back to the cell it last camped on or changes from the dedicated state CELL_DCH to the non-dedicated state in the serving cell, the problem that the network cannot accurately control the UE's access to the network often occurs

Embodiment 1

[0155] figure 1It is a flow chart of Embodiment 1 of the method for reading network access control parameters in the present invention. This embodiment is applicable to the case of controlling UE access in wireless network communication.

[0156] In the prior art, when the network is congested, the network restricts the access of some terminal UEs through the access control parameters in the SIB3. In SIB3, there are access control parameters of access levels 0 to 15. In order to prevent SIB3 from only updating the access control parameters of a small number of ACs each time, while UEs in other ACs need to read the power consumption caused by SIB3, The proposed solution is: if the UE has camped in a serving cell before, it will store the SIB3 of the serving cell and its tag value (Value Tag, VT for short), and after the UE reselects and switches out, the UE reselects back to For the serving cell, the UE first compares whether the stored VT of the SIB3 is consistent with the VT...

Embodiment 2

[0183] figure 2 It is a flow chart of Embodiment 2 of the method for reading network access control parameters of the present invention, as shown in figure 2 As shown, the method of this embodiment may include:

[0184] Step 201, the network device acquires a network status identifier;

[0185] In this step, the network device can determine whether the network status flag is TRUE (1) or FALSE (0) through background network management configuration or network algorithm.

[0186] Step 202, the network device sends the network status identifier to the user equipment UE, so that the UE determines whether to read a system information block according to the network status identifier.

[0187]The network device sends a master information block, a scheduling block, a system message change indication, a paging message, and a first system message block including the network state identifier to the UE.

[0188] In this step, the network status identifier sent by the network directly...

Embodiment 3

[0191] The method for obtaining network access control parameters in this embodiment may include:

[0192] When the user equipment UE enters the serving cell, no matter whether the tag value of the system message block stored by the UE is the same as the tag value of the system message block sent by the serving cell, the UE reads the system message of the serving cell block to obtain network access control parameters.

[0193] In this step, the user equipment entering the serving cell may specifically be: the UE reselects back to the serving cell; or the UE switches from a dedicated state to a non-dedicated state in the serving cell. The UE must read the system information block of the serving cell to obtain network access control parameters. The UE can also obtain the network access control parameters in the system information block, paging message, and system information changes of the serving cell. After acquiring the network access control parameters of the serving cell, ...

Abstract

Embodiments of the present invention provide a method and device for reading network access control parameters. The method for reading the network access control parameters of the present invention includes: the user equipment UE reselects back to the serving cell, or the UE switches from a dedicated state to a non-dedicated state in the serving cell; the UE acquires the network status identifier of the serving cell; Flag to determine if the system message block needs to be read. In the embodiment of the present invention, the call optimization system information block reading method reduces the power consumption caused by unnecessary reading of the system information block by the UE, so that the UE can update the stored system information block information in a timely manner, which is consistent with the network side. In order to make network access control more accurate.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a method and device for reading network access control parameters. Background technique [0002] In order to ensure the normal operation of the network, the network introduces an access control mechanism to restrict the access of some UEs or reject the service requests of some UEs. In a wireless communication system, when the network is congested, the network restricts the access of a user equipment (User Equipment, UE) through access control parameters in a system information block 3 (System Information Block 3, referred to as SIB3). [0003] Taking the Universal Mobile Telecommunications System (UMTS for short) as an example, the access control parameter may be an Access Class Barring (ACB for short) parameter in a system message block, an Access Class (Access Class, AC for short) may be 0 to 15, and the ACB parameter may indicate that the UE correspo...
