Description

Method and equipment for reading network access control parameters

Technical Field

The present invention relates to communications technologies, and in particular, to a method and a device for reading network access control parameters.

Background

In order to ensure the normal operation of the network, the network introduces an access control mechanism to limit the access of certain UEs or reject the service request of certain UEs. In a wireless communication system, when a network is congested, the network may limit access of a User Equipment (UE) through an access control parameter in a system message Block 3 (systeminformationblock 3, abbreviated as SIB 3).

Taking a Universal Mobile Telecommunications System (UMTS) as an example, the Access control parameter may be an Access Class Barring (ACB) parameter in a System message block, the Access Class (AC) may be 0 to 15, and the ACB parameter may indicate that the UE corresponding to one or several ACs is barred from accessing. Specifically, the network may perform network access control on the UE by sending a system message block to the UE, and the UE may determine whether the network can be accessed by reading ACB parameters included in the system message block.

However, in the prior art, when the UE reselects back to the cell where it last resided or changes from the dedicated state CE LL _ DCH to the non-dedicated state in the serving cell, a problem frequently occurs that the network cannot accurately control the UE to access the network.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Fig. 1 is a flowchart of a first embodiment of a method for reading network access control parameters according to the present invention, which is applicable to a case of controlling UE access in wireless network communication.

In the prior art, the network defines the access of certain terminal UEs by means of access control parameters in the SIB3 when the network is congested. The SIB3 has access control parameters of access levels 0-15, and in order to avoid the power consumption problem caused by the SIB3 only updating a small part of the access control parameters of the AC each time and the UE of other ACs need to read the SIB3, the proposed solution is: if the UE has previously resided in a serving cell, the SIB3 and its Tag Value (VT) of the serving cell are stored, and after the UE reselects and switches out, the UE reselects back to the serving cell, the UE first compares whether the stored VT of the SIB3 is consistent with the stored VT of the serving cell, and if the stored VT is the same, the UE does not read the SIB3 of the serving cell, and accesses the network according to the stored SIB 3. However, the above technical solution has some drawbacks, because the value range of the SIB3 is 1-4, if the SIB3 of the serving cell is updated faster, there may be a case that the VT of the SIB3 has been updated for a while, at this time, although the VT stored by the UE is the same as the VT of the serving cell, the actual content of the SIB3 stored by the UE is not consistent with the content of the SIB3 of the network, and when the network is congested, the network cannot control the access of the UE.

Therefore, the embodiment of the present invention provides a more reasonable method for reading network access control parameters, where the method of this embodiment may include:

step 101, when a user equipment UE enters a serving cell, the UE acquires a network state identifier of the serving cell.

In this step, the UE previously resided in the serving cell, and reselects back to the cell after reselecting and switching the UE; or the UE is changed from the dedicated state to the non-dedicated state in the serving cell.

In this step, when the UE resides in the serving cell before, the UE reads a 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 may be, for example, a system message block 5 or 7(SIB5 or SIB7), or another system message block including uplink interference information, and stores a network state identifier FA L SE or 0 if the read uplink interference value is less than or equal to a preset interference threshold value, and stores a network state identifier tune or 1 if the read uplink interference value is greater than the preset interference threshold value.

When the UE reselects back to the cell where the UE last resided, or the UE changes from the dedicated state to the non-dedicated state in the serving cell, the network state identifier stored in the serving cell where the UE last resided is obtained first.

Optionally, the UE may also receive a network status identifier sent by the serving cell in the master 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.

And step 102, the UE determines whether a system message block needs to be read according to the network state identifier.

In this step, the UE determines whether to read a system message block according to the acquired network status identifier, if the network status identifier is TRUE or 1, the UE needs to read a system message block including a network access control parameter sent by the serving cell, and correspondingly, determines whether to initiate 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 FA L SE or 0, if the tag value of the system message block is not changed, the UE uses the stored system message block as an effective system message block of the serving cell, and correspondingly, the UE determines whether to initiate access according to the network access control parameter included in the stored system message block of the serving cell.

The method for reading the network access control parameters provided by the embodiment of the invention determines whether the system message block needs to be read or not by acquiring the network state identifier of the serving cell through the UE, optimizes the method for reading the access control parameters, and ensures the consistency of the access control parameters of the UE side and the network side on the basis of reducing the power consumption caused by unnecessary reading of SIB3 by the UE, so that the network access control is more accurate.

On the basis of the above embodiment, optionally, if the UE resides in the serving cell before, the UE may read uplink interference information in a first system message block message sent by the network device, if the read uplink interference value is less than or equal to a preset interference threshold value, the UE stores a network state identifier as FA L SE or 0, if the read uplink interference value is greater than the preset interference threshold value, the UE stores a network state identifier as tune or 1.

In the embodiment, the network state identifier is determined by the uplink interference value acquired by the UE, so that the access control parameter in the system message block is selectively read, and consistency of the access control parameters of the UE side and the network side is ensured on the basis of reducing power consumption caused by unnecessary reading of SIB3 by the UE, so that network access control is more accurate.

Optionally, the UE may also directly indicate whether the UE needs to read the access control parameter in the system message block by receiving the network status identifier sent by the serving cell in the master information block, the scheduling block, the system message change indication, the paging message, and the first system message block.

In the above embodiment, the UE determines whether to read the access control parameter in the system message block according to the indication directly issued by the serving cell, so as to ensure consistency of the access control parameters of the UE side and the network side.

Optionally, when the UE reselects back to the serving cell, the current network system message block must be read again, and whether to initiate access is determined according to the access control parameter in the current network system message block.

On the basis of the above embodiment, the UE needs to read the uplink interference included in the first system message block sent by the serving cell to determine the network state before initiating access, and if the network state of the cell that resided last time is stored, the network state identifier stored by the UE needs to be updated, specifically, if the acquired uplink interference value is less than or equal to the preset interference threshold value, the network state identifier of the serving cell that resided last time is updated to FA L or 0, and if the acquired uplink interference value is greater than the preset interference threshold value, the network state identifier of the serving cell that resided last time is updated to TRUE or 1.

The following describes the technical solution of the above-described method embodiment in detail by using several specific application scenarios.

Scenario one, the network state of the serving cell is changed from congestion to non-congestion

When the UE reselects back to the serving cell, or the UE is switched from a dedicated state to a non-dedicated state in the serving cell, and the network state identifier stored in the UE before the UE enters the serving cell again is "tune" or "1", therefore, when the UE re-enters the serving cell, the UE needs to read the access control parameter in the system message block of the serving cell, before the UE initiates access, the uplink interference value in SIB7 needs to be read, and the obtained uplink interference value is smaller than the preset threshold value, then the network state identifier stored in the UE is updated to FA L or SE 0.

Scenario two, serving cell network state is continuously congested

When the UE reselects back to the serving cell, or the UE is converted from a dedicated state to a non-dedicated state in the serving cell, and the network state identifier stored before the UE is turn or 1, therefore, when the UE re-enters the serving cell, the UE needs to read the access control parameter in the system message block of the serving cell, and before the UE initiates access, the uplink interference value in SIB7 needs to be read, and if the obtained uplink interference value is greater than the preset threshold value, the network state identifier stored by the UE is updated to turn or 1.

Scenario three, the network state of the service cell is converted from non-congestion to congestion

When the UE reselects back to the serving cell, or the UE is converted from a dedicated state to a non-dedicated state in the serving cell, and the network state identifier stored before the UE is FA L SE or 0, therefore, when the UE reenters the serving cell, the UE does not need to read the access control parameter in the system message block of the serving cell, the UE determines whether the UE initiates access according to the stored access control parameter of the last resident serving cell, the uplink interference value in the SIB7 needs to be read before the UE initiates access, the acquired uplink interference value is greater than the preset threshold value, the network state identifier stored by the UE is updated to TURE or 1, and at this time, the UE needs to read the access control parameter in the new system message block of the serving cell, and determines whether to initiate access according to the new access control parameter.

Scene four, the network state of the service cell is always kept as the non-congestion state

When the UE reselects back to the serving cell, or the UE is converted from a dedicated state to a non-dedicated state in the serving cell, and the network state identifier stored before the UE is FA L SE or 0, therefore, when the UE reenters the serving cell, the UE does not need to read the access control parameter in the system message block of the serving cell, and then the UE determines whether the UE initiates access according to the stored access control parameter of the last resident serving cell, the uplink interference value in SIB7 needs to be read before the UE initiates access, the obtained uplink interference value is smaller than a preset threshold value, and the network state identifier stored by the UE is updated to FA L SE or 0.

The technical scheme provided by the embodiments of the method makes the access control parameter of the UE side consistent with the latest access control parameter content of the network by updating the stored network state identification in time, and ensures that the network access control strength is more accurate.

Example two

Fig. 2 is a flowchart of a second embodiment of a method for reading network access control parameters, as shown in fig. 2, the method of this embodiment may include:

step 201, a network device acquires a network state identifier;

in this step, the network device may determine that the network status identifier is tune (1) or FA L SE (0) through the background network management configuration or the network algorithm.

Step 202, the network device sends the network status identifier to a user equipment UE, so that the UE determines whether a system message block needs to be read according to the network status identifier.

In this step, a network state identifier sent by a network directly indicates whether User Equipment (UE) needs to read access control parameters in a system message block, if the network state identifier is TRUE or 1, the UE is indicated to read the system message block regardless of whether the label value of the system message block changes, if the network state identifier is FA L SE or 0, if the label value of the system message block does not change, the UE is indicated to use the stored system message block as an effective system message block of the serving cell;

in the method for reading the network access control parameter provided by this embodiment, the network issues the network status identifier to indicate whether the UE needs to read the access control parameter in the system message block, and the access control parameter is selectively read according to the network indication, thereby ensuring more accurate network access control.

EXAMPLE III

The method for acquiring the network access control parameter of the embodiment may include:

In this step, the entering of the ue into the serving cell may specifically be: the UE reselects back to the serving cell; or the UE is changed from the dedicated state to the non-dedicated state in the serving cell. The UE must read the system message block of the serving cell to obtain the network access control parameter, or the UE may determine whether to initiate access according to the network access control parameter of the serving cell after obtaining the network access control parameter of the serving cell by obtaining the system message block, the paging message, and the network access control parameter in the system message change of the serving cell.

In this embodiment, when the UE reselects back to the serving cell, it is necessary to re-read the current network system message block, and determine whether to initiate access according to the access control parameter in the current network system message block, so as to ensure consistency between the UE side and the network access control parameter.

Step 302, the UE determines whether the UE of the access class needs to read a system message block according to the indication information corresponding to the access class of the UE in the access class list.

In this step, the UE determines according to the received indication information corresponding to the access class AC, determines that the access control parameter in the system message block needs to be read if the indication information is TRUE or 1, and updates the stored system message block and the tag value of the system message block accordingly, and determines that the access control parameter in the system message block does not need to be read if the indication information is FA L SE or 0, and accordingly, the UE reads the tag value of the system message block in the master information block or the scheduling block and updates the stored tag value of the system message block.

In the method for reading the network access control parameter provided in this embodiment, the UE reads the indication information sent by the network, and selects the UE corresponding to the AC with the changed access parameter to read the system message block, so that the accuracy of network access control is ensured on the basis of reducing power consumption caused by unnecessary reading of the SIB3 by the UE.

EXAMPLE five
