The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Embodiment 1

FIG. 1 is a flowchart of Embodiment 1 of a method for reading network access control parameters according to the present invention. This embodiment is applicable to a case where UE access is controlled in wireless network communication.

In the prior art, the network defines access of certain terminal UEs through access control parameters in the SIB3 when the network is congested. In SIB3, there are access control parameters of access levels 0 to 15. In order to prevent SIB3 from updating only a small number of AC access control parameters at a time, other AC UEs need to read the power consumption problem caused by SIB3. The proposed solution is as follows: If the UE has previously camped on a serving cell, the SIB3 of the serving cell and its Tag Value (VT) are stored. After the UE reselects and switches out, the UE reselects the UE. The serving cell, the UE first compares whether the VT of the stored SIB3 and the VT of the serving cell are consistent. If the VT is the same, the UE no longer reads the SIB3 of the serving cell, and accesses the network according to the stored SIB3. However, the above technical solution also has some drawbacks. Since the VT of the SIB3 ranges from 1 to 4, if the SIB3 of the serving cell is updated faster, there may be a VT of the SIB3 that has been updated, but at this time, although the UE stores The VT of the serving cell is the same as the VT of the serving cell, but the content of the SIB3 stored by the actual UE and the SIB3 of the network are inconsistent. When the network is congested, the network cannot be controlled. The access of the above UE is made.

To this end, the embodiment of the present invention provides a method for reading a more reasonable network access control parameter. The method in this embodiment may include:

Step 101: When the user equipment UE enters the serving cell, the UE acquires a network status identifier of the serving cell.

In this step, the UE has previously camped on the serving cell, and after the UE reselects the handover, the UE reselects the cell back to the cell; or the UE transitions from the dedicated state to the non-dedicated state in the serving cell.

Take UMTS as an example. When the traffic volume of a cell is larger, the interference in the cell will be larger. When the traffic volume of the cell is larger, congestion may occur. In this case, the network access control parameters need to be adjusted. In this step, when the UE is camped on the serving cell, the UE reads the first system message block sent by the network device, where the first system message block includes uplink interference information, where the first system message block is, for example, It may be system message block 5 or 7 (SIB5 or SIB7), or other system message block including uplink interference information; if the read uplink interference value is less than or equal to a preset interference threshold, the UE stores the network status identifier. It is FALSE or 0; if the read uplink interference value is greater than the preset interference threshold, the UE stores the network status identifier as TURE or 1. The preset interference threshold may be configured by the serving cell or may be predefined by the UE.

When the UE reselects the cell that was last camped last or the UE transitions from the dedicated state to the non-dedicated state in the serving cell, the network state identifier of the UE that last stored in the serving cell is stored first.

Optionally, the UE may also receive a network status identifier sent by the serving cell in the primary information block, the scheduling block, the system message change indication, the paging message, and the first system message block, where the network status identifier is used to directly indicate Whether the UE needs to read the system message block. For example, if the indication is 1, the UE needs to read the system message block; if the indication is 0, the UE does not need to read the system message block.

Step 102: The UE determines, according to the network status identifier, whether a system message block needs to be read.

In this step, the UE determines whether it needs to read the system message block according to the acquired network status identifier. If the network status identifier is TRUE or 1, the UE needs to read the serving cell to send. a system message block including a network access control parameter, and correspondingly, determining whether to initiate an access according to a network access control parameter included in the system message block after reading the system message block; if the network status identifier is FALSE or 0, if The tag value of the system message block is unchanged, and the UE uses the stored system message block as a valid system message block of the serving cell; correspondingly, the UE may use the stored system message of the serving cell. The network access control parameters included in the block determine whether to initiate access.

The method for reading the network access control parameter provided by the embodiment of the present invention determines whether the system message block needs to be read by the UE acquiring the network status identifier of the serving cell, and optimizes the reading method of the access control parameter, and reduces the UE It is necessary to read the power consumption of the SIB3 to ensure the consistency of the access control parameters between the UE side and the network side, so that the access control of the network is more accurate.

On the basis of the foregoing embodiment, optionally, if the UE is previously camped on the serving cell, the UE reads the uplink interference information in the first system message block message sent by the network device, if the uplink interference is read. If the value is less than or equal to the preset interference threshold, the UE stores the network status identifier as FALSE or 0. If the read uplink interference value is greater than the preset interference threshold, the UE's storage network status identifier is TURE or 1. The preset interference threshold may be configured by the serving cell, or may be predefined by the UE. When the UE reselects the serving cell or the UE transitions from the dedicated state to the non-dedicated state in the serving cell, the first time is obtained. The network status identifier of the UE that last camped on the serving cell. The UE determines whether it needs to read the system message block according to the obtained network status identifier. If the network status identifier is TRUE or 1, the UE needs to read the system message block that is sent by the serving cell and includes the network access control parameter, and accordingly, Determining whether to initiate an access according to the network access control parameter included in the system message block after reading the system message block; if the network status identifier is FALSE or 0, if the label value of the system message block does not change, the UE uses The stored system message block is used as an effective system message block of the serving cell; correspondingly, the UE determines whether to initiate access according to the stored network access control parameter included in the system message block of the serving cell.

The foregoing embodiment determines the network status identifier by using the uplink interference value obtained by the UE, so as to selectively read the access control parameter in the system message block, and ensures the UE on the basis of reducing the power consumption caused by the unnecessary reading of the SIB3 by the UE. The access control parameters of the side and the network side are consistent, so that the access control of the network is more accurate.

Optionally, the UE may also receive the serving cell in the primary information block, the scheduling block, and the system message. Direct indication of the change indication, paging message, network status identifier sent in the first system message block

Or 0.

Scenario 2: The service cell network status continues to be congested.

When the UE reselects to the serving cell, or the UE transitions from the dedicated state to the non-dedicated state in the serving cell, the network state identifier previously stored by the UE is TURE or 1, so when the UE re-enters the serving cell, the UE needs to read the serving cell. The access control parameter in the system message block needs to read the uplink interference value in the SIB7 before the UE initiates the access, and the obtained uplink interference value is greater than the preset threshold, and the network status identifier stored by the UE is updated to TURE or 1 .

Scenario 3: The serving cell network status changes from non-congested to congested.

When the UE reselects to the serving cell, or the UE transitions from the dedicated state to the non-dedicated state in the serving cell, the network state identifier previously stored by the UE is FALSE or 0, so the UE re-enters When the UE enters the serving cell, the UE does not need to read the access control parameter in the serving cell system message block, and the UE determines whether the UE initiates the access according to the stored last access control parameter of the serving cell, and initiates the UE. The uplink interference value in the SIB7 needs to be read before the access, and the obtained uplink interference value is greater than the preset threshold. The network status identifier stored by the UE is updated to TRUE or 1. The UE needs to read the new system message of the serving cell. An access control parameter in the block determines whether to initiate an access according to the new access control parameter.

Scenario 4: The service cell network status continues to be uncongested.

When the UE reselects to the serving cell, or the UE transitions from the dedicated state to the non-dedicated state in the serving cell, the network state identifier previously stored by the UE is FALSE or 0, so the UE does not need to read the service when the UE re-enters the serving cell. The access control parameter in the cell system message block, the UE determines whether the UE initiates the access according to the stored last access control parameter of the reserved serving cell, and needs to read the uplink interference in the SIB7 before the UE initiates the access. The obtained uplink interference value is less than the preset threshold, and the network status identifier stored by the UE is updated to FALSE or 0.

The technical solution provided by the foregoing method embodiments keeps the storage network state identifiers in a timely manner, so that the access control parameters of the UE side and the latest access control parameter contents of the network are consistent, thereby ensuring more accurate network access control.
