Description

Method, device and storage medium for obtaining access control parameters Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a method, an apparatus, and a storage medium for acquiring access control parameters.

Background technique

In a wireless communication network, a user equipment (UE) selects a cell access and performs data interaction with the network side through the accessed cell. However, in order to control the number of UEs accessing the same cell, to balance the load of the cell, the UE needs to perform an AC barring (Access Control Barring) decision before accessing the cell to determine whether the UE can access the current Community. However, before performing the AC barring decision, the UE needs to obtain access control parameters from the network side.

In order to ensure that the UE in the idle state or the UE in the inactive state can acquire the access control parameters before accessing the cell, the access control parameter usually needs to be broadcast in the system message. Currently, system messages other than the MIB (Master Information Block) are classified into RMSI (Remaining Minimum System Information) and other system messages (other SI). Since the access control parameters of NR (New Radio) are abnormally large, and the maximum transport block size of RMSI or other SI is 3000 or less, consider placing part of the access control parameters in RMSI for transmission. Part of the access control parameters are transmitted in Other SI. However, the RMSI is also sent by means of broadcast, and the other SI needs to be sent by means of the UE request, that is, the UE first sends a system message acquisition request, and after the network side receives the system message acquisition request, the system message is scheduled. The other SI is broadcast in the time window, and for the UE in the idle state or the UE in the inactive state, the system message acquisition request can be currently sent through the MSG1 and the MSG3 in the random access procedure.

In order to ensure that the UE in the idle state or the UE in the inactive state can acquire the access control parameters before accessing the cell, the access control parameter usually needs to be broadcast in the system message. However, since some of the access control parameters are transmitted in the RMSI, other part of the access control parameters are transmitted in the Other SI. The RMSI is sent by broadcast, while the other SI needs to be sent by the UE request. Therefore, for other SI, after the UE sends the system message acquisition request, it does not receive the other SI broadcasted by the network side, then how to deal with it at this time, and no implementation scheme is currently given. However, the embodiment of the present disclosure is applied to the above scenario to determine how to determine access control parameters in case of failure of acquisition. The method for obtaining the access control parameter provided by the embodiment of the present disclosure is explained in detail below.

FIG. 2 is a flowchart of a method for obtaining an access control parameter according to an embodiment of the present disclosure. Referring to Figure 2, the method includes the following steps:

In step 201, the UE sends a system message acquisition request to the network side, where the system message acquisition request is used to obtain an access control parameter corresponding to the target access category, and the target access category is used to indicate the service currently initiated by the UE.

Since a part of the access control parameters are transmitted in the RMSI, and other part of the access control parameters are transmitted in the Other SI, in the embodiment of the present disclosure, in order to obtain the access control parameters transmitted in the Other SI, the UE needs to request Way to get it. That is, the UE needs to send a system message acquisition request to the network side.

The access control parameter usually includes a random number and a valid duration, and the random number is used to determine whether the currently accessed cell is restricted from accessing, and the effective duration is a duration in which the cell is restricted from accessing.

In step 202, when the UE determines that the access control parameter corresponding to the target access category fails to be acquired, the reference access category corresponding to the target access category is obtained.

Since the other SI needs the UE to acquire in the requested manner, after the UE sends the system message acquisition request to the network side through the foregoing step 201, if the network side receives the system message acquisition request, the network side may be in the scheduling time of the system message. The other SI is broadcast in the window, wherein the scheduling time window of the system message refers to the time window for broadcasting the other SI. In this way, when the UE receives the other SI, the access control parameter corresponding to the target access category may be obtained from the other SI, that is, the access control parameter corresponding to the target access category may be successfully obtained. When the network side does not receive the system message acquisition request, or the network side broadcasts other SI but the UE does not receive the other SI, it may determine that the access control parameter corresponding to the target access category fails to be acquired. That is, the reason for the failure of the parameter acquisition may be the cause of the network, or may be other reasons. Therefore, in the embodiment of the present disclosure, the UE may acquire the reference access category corresponding to the target access category, and then perform the following steps. 203-204 obtains an access control parameter corresponding to the reference access category, so as to determine an access parameter corresponding to the target access category.

In the embodiment of the present disclosure, the UE may store a category mapping relationship for storing a mapping relationship between each access category and a corresponding reference access category. In this way, the UE can obtain the reference access category corresponding to the target access category from the stored category mapping relationship.

The class mapping relationship may be that the network side is notified to the UE by using a broadcast message or an RRC release message; or the class mapping relationship is that the network side notifies the UE by using an attach signaling process or a tracking area update process; or The mode is written in the UE. That is, the class mapping relationship may be notified to the UE by the network side by means of the radio access network, or may be notified to the UE by means of the non-access stratum, or may be agreed in advance and written to the UE in firmware.

It should be noted that when the category mapping relationship is notified to the UE by using a broadcast message, the broadcast message may be an RMSI, and of course, other broadcast messages may also be used. When the category mapping relationship is notified to the UE by using the RRC release message, the category mapping relationship may include only the target access category and the relationship between the reference access categories corresponding to the target access category. Of course, in order to facilitate the UE. The AC barring decision is performed when other services are initiated, and the category mapping relationship may also include a mapping relationship between each access category and a reference access category corresponding to each access category. When the class mapping relationship is notified to the UE by the attach signaling process or the tracking area update process, the class mapping relationship may be carried and notified to the UE in any signaling that interacts with the UE in the attach signaling process or the tracking area update process. . For example, when the non-access stratum identifies an access attempt, the access request may be sent to the access layer, and the access request may carry the category mapping relationship in addition to the access category corresponding to the access attempt. For example, when the non-access stratum identifies an access attempt, the access request may be sent to the access layer, where the access request carries the access category corresponding to the access attempt, and the access layer of the UE acquires the target connection. After the failure of the incoming access control parameters of the class, the UE will request the corresponding reference access category from the non-access stratum.

In a possible implementation manner, when the UE can learn the class mapping relationship through the broadcast message and the class mapping relationship through the RRC release message, the class mapping relationship in the RRC release message is updated in time, so The class mapping relationship in the RRC release message is preferred.

Optionally, when the class mapping relationship is that the network side notifies the UE by using an RRC release message, the RRC release message may further carry at least one of a valid time range and a valid area range. In this way, before the UE obtains the reference access category corresponding to the target access category from the stored category mapping relationship, the UE may determine whether the UE currently satisfies the reference access category by using at least one of the valid time range and the valid area range. condition. That is, before the UE obtains the reference access category corresponding to the target access category from the stored category mapping relationship, the UE may further include at least one of the following:

When the RRC release message carries a valid time range, and the current time is in the valid time range, performing a step of acquiring a reference access category corresponding to the target access category from the stored category mapping relationship;

When the RRC release message carries the valid area range, and the current location is in the valid area range, the step of obtaining the reference access category corresponding to the target access category from the stored category mapping relationship is performed.

It should be noted that when the class mapping relationship is notified to the UE by other means, at least one of the valid time range and the valid area range may be notified to the UE, that is, when the UE learns the class mapping relationship by other means, and When the reference access category corresponding to the target access category is obtained in the category mapping relationship, it may also be determined whether the current time is in the valid time range, and whether the current location is in the valid area range, and then in the valid time range and/or When it is in the effective area, the step of obtaining the reference access category corresponding to the target access category from the stored category mapping relationship is performed. In addition, the effective time range and the effective area range may be configured by the system, or may be configured by the network side, which is not limited by the embodiment of the present disclosure.

In the embodiment of the present disclosure, the reason for the failure of the parameter acquisition may be the cause of the network, or may be other reasons. Therefore, after the access control parameter corresponding to the target access category fails to be acquired, in order to pass the target access category. The corresponding access control parameter is used to perform an AC barring decision on the service currently initiated by the UE. The embodiment of the present disclosure acquires a reference access category corresponding to the target access category, and obtains an access control parameter corresponding to the reference access category. However, before the UE acquires the reference access category corresponding to the target access category, the UE may further determine whether the condition for determining the access parameter corresponding to the target access category by using the access parameter corresponding to the reference access category is met, that is, Is the parameter acquisition condition. When it is determined that the parameter acquisition condition is currently satisfied, the step of obtaining the reference access category corresponding to the target access category from the category mapping relationship is performed. When it is determined that the parameter acquisition condition is not met, the system message acquisition request may be sent to the network side to obtain the access control parameter corresponding to the target access category.

The parameter acquisition condition may be that the network side is notified to the UE by using a broadcast message or an RRC release message; or the parameter acquisition condition is that the network side notifies the UE by using an attach signaling process or a tracking area update process; or The mode is written in the UE. That is, the notification manner of the parameter acquisition condition is the same as the notification manner of the category mapping relationship, and the embodiments of the present disclosure are not described in detail herein.

In a possible implementation manner, the parameter obtaining condition may be that the number of times that the access control parameter corresponding to the target access category fails has reached a threshold value, and the threshold may be set in advance, for example, 1 time, 3 times, and the like.

In a possible implementation manner, when the UE does not obtain the reference access category corresponding to the target access category, the operation may be ended, that is, the access control corresponding to the reference access category is not performed. The steps of the parameters.

It should be noted that the access categories are generally classified into standard access categories and non-standard access categories. The standard access categories are the access categories specified in the protocol, and the non-standard access categories are defined by the operators. Into the category. In the embodiment of the present disclosure, the target access category may be a non-standard access category, and the reference access category may be a standard access category; or the target access category and the reference access category are non-standard accesses. Category; or, both the target access category and the reference access category are standard access categories.

In an exemplary embodiment, the access categories may include 64, and the definitions of the 64 access categories are as shown in Table 1 below.

Table 1

Among the 64 access categories provided above, the access categories numbered 0-7 are standard access categories, and the access categories numbered 8 to 31 are reserved standard access categories. The access categories of 32 to 63 are non-standard access categories, that is, the access categories defined by the operators.

For example, the target access category may be one of the access categories numbered 32-63, and the reference access category may be one of the access categories numbered 0-7; or the target access category is number 32. One of the access categories of ～63, the reference access category is the other one of the access categories numbered 32-63; or the target access category is one of the access categories numbered 0-7, refer to The access category is the other of the access categories numbered 0-7.

The PLMN is a network established by operators for the purpose of providing land mobile communication services to the public. For example, China Mobile's PLMN is 46,000, and China Unicom's PLMN is 46001. That is, in the actual life, there are a plurality of different PLMNs, and different services can be provided in the same PLMN, and the access categories are generally used to indicate the services initiated by the UE. Therefore, in the embodiment of the present disclosure, the target access category And the reference access category may be an access category in the same PLMN; or, the target access category and the reference access category may be access categories in different PLMNs.

For example, the target access category is one of the access categories numbered 0-7 in the HPLMN, and the reference access category is the other one of the access classes numbered 0-7 in the HPLMN. Alternatively, the target access category is one of the access categories numbered 0-7 in the non-HPLMN, and the reference access category is the other one of the access classes numbered 0-7 in the HPLMN.

In step 203, the UE acquires the access control parameter corresponding to the reference access category, and uses the access control parameter corresponding to the reference access category as the access control parameter corresponding to the target access category.

As can be seen from the description of the foregoing step 202, the reference access category may be a standard access category or a non-standard access category, and a part of the access control parameters are transmitted in the RMSI, and another part of the access is transmitted in the other SI. Control parameters. Generally, the RMSI transmits the access control parameters corresponding to the standard access category, and the other SI transmits the access control parameters corresponding to the non-standard access categories. Therefore, when the parameter access category is the standard access category, The access control parameter corresponding to the reference access category may be obtained from the RMSI broadcasted by the network side.

However, when the reference access category is a non-standard access category, the system message acquisition request may be sent to the network side, that is, equivalent to resending the system message acquisition request, which may increase the success rate of acquiring other SI. . When the network side receives the system message acquisition request, the other SI may be broadcasted in the scheduling time window of the system message, so that when the UE receives the other SI, the access control corresponding to the reference access category may be obtained from the other SI. The parameter, and the access control parameter corresponding to the access category is used as the access control parameter corresponding to the target access category. Of course, since the UE can receive the other SI, the access control parameters corresponding to the target access category can also be obtained directly from the other SI. When the network side does not receive the system message acquisition request, or the network side broadcasts the other SI but the UE does not receive the other SI, it may determine that the access control parameter corresponding to the reference access category fails to be acquired. In summary, when the UE does not receive the other SI, it may be determined that the access control parameter corresponding to the reference access category fails to be acquired.

In step 204, when it is determined that the access control parameter corresponding to the reference access category fails to be obtained, the access control parameter corresponding to the target access category is set as a default parameter, or the currently accessed cell is restricted to access.

In the first possible implementation manner, when it is determined that the access control parameter corresponding to the reference access category fails to be acquired, the access control parameter corresponding to the target access category is set as a default parameter.

The default parameter is the parameter with the largest value in the protocol; or the default parameter is the last parameter in the application sorting mechanism; or the default parameter is that the network side notifies the UE by using a broadcast message or an RRC release message; or, the default The parameter is that the network side notifies the UE through the attach signaling process or the tracking area update process; or the default parameters are written into the UE in firmware in advance.

It should be noted that a plurality of access control parameters are usually specified in the protocol. Therefore, when the other SI cannot be obtained, the default parameter is set to the parameter with the largest value in the protocol, so that the most stringent requirements can be used. The AC barring decision can further balance the load on the cell. In addition, there may be multiple applications in the UE that can initiate services. Therefore, the AC barring decision needs to be performed on the services initiated by the multiple applications. Generally, the access control parameters for performing AC barring decisions on the multiple applications may be sorted by application. The mechanism sorts, so you can also set the default parameter to the last parameter in the application sorting mechanism. Since the last parameter of the sorting is usually the most expensive parameter, you can also use the most stringent requirements for AC. The barring decision can further balance the load on the cell. Finally, the remaining notification manners are the same as the notification manners of the above-mentioned category mapping relationship, and the embodiments of the present disclosure do not elaborate on this.
