As shown in FIG. 1 , an embodiment of the present disclosure provides an access control method, which, when applied to a user equipment UE, includes:

S110: According to the access types of the multiple services, make a binding decision for access control.

In the embodiment of the present disclosure, the multiple services here may be: multiple services have transmission requirements in the same time period, and there may be multiple services that will trigger access.

In the embodiments of the present disclosure, access control is no longer performed independently according to the access type of each service requested (or initiated) to access, so as to determine whether each service allows or prohibits access to the corresponding service. In the embodiment of the present disclosure, considering that the multiple services with initiating access belong to the same UE, and considering the correlation between multiple services, the access of multiple related services is reduced, and some Some services are rejected and some are accepted, which in turn leads to some services in multiple related services being refused access, and some services are allowed to access; resulting in inconsistent service data transmission delays of related services.

In view of this, the embodiments of the present disclosure provide a technical solution that allows access control of multiple services that request access to be determined by binding.

The binding judgment here can be understood as: comprehensive judgment.

The result of the binding judgment may include: the access initiated by multiple services needs to be followed; thus, the binding judgment is: the access control of at least two services in the multiple services will affect each other.

In a word, in the embodiment of the present disclosure, the binding decision will obtain a binding decision result, and the binding decision result is the final result of the access control of any one of the multiple services. Whether or not to initiate the access of the aforementioned multiple services is determined according to the binding judgment result.

In this embodiment of the present disclosure, the UE may choose to make separate judgments for access triggered by multiple services, or may choose to make binding judgments. For example, when it is determined that the conditions for the binding judgment are satisfied, for the access triggered by multiple services, the binding judgment of access control is performed according to the access types of the multiple services.

For example, the conditions for satisfying the binding decision may include at least one of the following:

Multiple services that trigger access come from the same application;

Multiple services that trigger access come from the same service;

An input instruction indicating a binding judgment is detected; the input instruction specifies that access triggered by multiple services requires a binding judgment;

The service type set of binding judgments specified by the binding judgment configuration of multiple services that trigger access;

The UE is currently in binding decision mode.

Of course, the above example illustrates that the UE performs binding judgment on the access control of multiple services that trigger access, but the specific implementation is not limited to this.

When performing access control, the AC layer needs to perform access control according to the access type described in the service for which the access is to be initiated. For example, after the AC layer knows the access type of the corresponding service, it can query the corresponding access parameters, so as to implement access control according to the access parameters.

The access control here may include: access control based on the access level; or, generating a random number, comparing the random number with the access factor, and performing the access control based on the comparison result.

The result of access control is: allow access or prohibit access.

In one embodiment, the access type includes:

Single-modal access type, which is the access type of a single-modal service;

and / or;

The multi-modal access type is an access type combining different modal services.

For example, voice data, video data and text data correspond to three single modalities.

For example, mixed data of speech data and text data corresponds to two modalities.

For another example, the data collected by different devices are attributed to different single modalities, for example, the data collected by keyboards, speakers, cameras, fingerprint collectors, environmental sensors or motion sensors belong to different single modalities. The combination of any two or more unimodal data corresponds to multimodality.

Specifically, how to combine the access types of the multiple services to perform the binding judgment of the access control triggered by the multiple services can be implemented according to the AC judgment rule.

AC decision rules may include: one or more rule entries.

These rule entries may include: conditions and actions, where the conditions define the conditions under which the corresponding actions are performed, and the actions point to specific binding decisions.

For example, the AC decision rule includes one or more decision rules. Typically, the AC decision rule corresponds to different situations, and different decision rules are configured.

In some embodiments, the AC decision rule includes: a first decision rule, and according to the first decision rule, the S110 may include:

In response to the single-modal access types corresponding to the multiple services being the same, the non-access NAS layer sends parameter information of the single-modal access types corresponding to the multiple services to the AS layer; or, in response to the multiple services Each service corresponds to the same multimodal service type, and the NAS layer sends parameter information of the multimodal service type corresponding to the multiple services to the AS layer;

The AS layer makes a decision on access control of the multiple services according to the received parameter information.

Here, the parameter information sent by the NAS layer to the AS layer at least includes: an access type, and in some embodiments, may also include: an AC barring (barring) parameter and the like.

The AC prohibition parameters include but are not limited to:

The timing duration of the prohibition timer;

Access class for which access is prohibited;

The factor for barring access.

Of course, the above is only an example of the AC prohibition parameter, and the specific implementation is not limited to this.

Scenario 1: Since multiple services correspond to the same single-modal access type, when making a binding decision, only one decision needs to be made according to the single-modal access type. The single-modal access control decision, the binding decision in this case, can reduce the number of decisions at the AS layer and improve the decision rate.

Case 2: Because multiple services correspond to the same multimodal access type.

In this case, in order to reduce the decision of access control, the NAS layer can only send the parameter information of the access types corresponding to the multiple services of the sender to the AS layer, and the AS layer can complete an access control decision. Thus, the number of decisions of the AS layer is reduced, and the decision rate is improved.

In this embodiment of the present disclosure, the first decision rule may correspond to access types of multiple services, and is a binding decision for the same multimodal service type or single-modal service type. The binding judgment based on the first judgment rule is a single judgment operation for a single access type corresponding to multiple services, and the binding judgment result of the binding judgment of access triggered by multiple services can be obtained. Therefore, the condition for the first decision rule to be hit is: the access types of multiple access-initiating services correspond to the same multi-modal access type or the same single-modal access type.

In one embodiment, the AC decision rule further includes: a second decision rule;

As shown in FIG. 3 , the S110 may include:

S111: According to the second decision rule, in response to the different access types corresponding to the multiple services, the NAS layer sends parameter information of each access type corresponding to the multiple services to the AS layer; wherein the Different access types corresponding to multiple services, including: different single-modal access types and/or different multi-modal access types;

S112: According to the received parameter information of each access type, the AS layer performs an independent judgment on a single access type in the multiple services, and obtains an independent judgment result;

S113: Determine the binding judgment results of the multiple services according to the individual judgment results.

In this embodiment of the present disclosure, the NAS layer of the UE determines that multiple services correspond to multiple different access types, and the multiple access types may include: any number of the aforementioned single-modal access types and/or Any number of multimodal access types. It is determined at the NAS layer that there are multiple access types corresponding to the multiple services that currently need to be bound and determined, then the NAS will pass the parameter information of the access types corresponding to the multiple services to the AS layer. After receiving the parameter information, the parameter information corresponding to the access type is judged separately, and the judgment result is obtained. Such verdicts are called separate verdicts. The detailed implementation manner of this individual decision may be the same as or similar to the decision manner of access control in the related art.

Due to the binding judgment of multiple services, and since multiple services correspond to different access types, in the embodiment of the present disclosure, a separate judgment is made for each access type, and after the independent judgment result is obtained, based on the independent judgment As a result, further decisions are made to obtain the result of the binding decision. In this judgment mode, compared with the single judgment, there will be one more operation for further judgment combined with multiple single judgment results.

In an embodiment, the NAS layer sends parameter information of each access type corresponding to the multiple services to the AS layer, including:

The NAS layer delivers the parameter information of each access type corresponding to the multiple services to the AS layer at one time.

In the embodiment of the present disclosure, the NAS layer switches the parameter information of multiple access types corresponding to multiple services to the AS layer at one time, so that the AS layer will receive the access types corresponding to multiple services at one time. Parameter information.

For example, in some embodiments, the NAS layer sends the parameter information of the access types corresponding to multiple services to the AS layer at one time in the form of a table. In this way, when the AS layer performs access control of a single access type, the parameter information of the access type can be obtained by querying the table, and then the access control of a single access type can be obtained to obtain multiple judgment results.

After the individual decision results are obtained, a final comprehensive decision may be made according to one or more of the individual decision results to obtain the binding decision result.

In some embodiments, the S113 may include: determining the binding decision result according to the second decision rule and the individual decision result.

When the UE generates a binding decision result based on the individual decision results, the binding decision result is formed by processing one or more individual decision results according to the second decision rule.

In one embodiment, the second decision rule includes one of the following:

and rules, which are: the rules for obtaining the binding judgment by performing a logical sum operation on a plurality of the individual judgment results;

The OR rule is: a rule for obtaining the binding decision by performing a logical OR operation on a plurality of the individual decision results.

The individual decision rule can be identified by a Boolean quantity, and "0" and "1" of the Boolean quantity correspond to access permission and access prohibition respectively.

In this way, when there are multiple independent judgment results that need to generate binding judgment results, if the AS judgment rule is an AND rule, the Boolean quantities of the multiple independent judgment results are logically ANDed to obtain a binding semi-decision result. In this way, when each individual decision result is access allowed, the binding decision result is also allowed to access. If at least one of the multiple individual judgment results is a judgment result of prohibiting access, the binding judgment result is also prohibiting access.

If the OR rule is adopted, multiple individual decision results will be logically ORed to obtain a bound decision result. In this way, if one of the multiple individual decision results is access allowed, the obtained binding decision result is access allowed, and only when all the individual decision results of the individual decision results are access prohibited. , and the obtained binding judgment result is that access is prohibited.

In one embodiment, the second decision rule may further include:

The hierarchical rule is: a rule for obtaining the binding decision according to a separate decision result of a predetermined hierarchical access type.

For example, the access type is divided into two or more levels; if the access types corresponding to multiple services are also divided into multiple levels, all or part of the independent judgment results of the high-level independent judgment results are allowed to access. access, it can be considered that the result of the binding judgment of these multiple services is access allowed.

Therefore, in one embodiment, determining the binding decision result according to the second decision rule and the individual decision result includes:

According to the AND rule, a logical AND operation is performed on a plurality of the individual decision results to obtain a result of the binding decision.

In another embodiment, the determining the binding decision result according to the second decision rule and the individual decision result includes:

According to the OR rule, a logical OR operation is performed on a plurality of the individual judgment results to obtain a binding judgment result.

In yet another embodiment, the determining the binding decision result according to the second decision rule and the individual decision result includes: including:

According to the hierarchical rule, when the individual decision result of the predetermined hierarchical access type is access allowed, generating a binding decision result indicating that the multiple services are allowed to access;

or,

According to the hierarchical rule, when at least one of the individual decision results of the predetermined hierarchical access type prohibits access, a binding decision result indicating that the multiple services are prohibited from being accessed is generated.

In one embodiment, the AC decision rule further includes: a third decision rule; according to the third decision rule, the S110 may include:

In response to the different access types corresponding to the multiple services, the NAS layer sends parameter information of each access type corresponding to the multiple services to the AS layer;

A piece of target parameter information corresponding to a plurality of the access types received by the AS layer, wherein the target parameter information is: performing an access control decision according to the target parameter information to obtain bindings of the plurality of services. determine the verdict.

In order to further simplify the process of binding decision, in this embodiment of the present disclosure, separate decisions for each access type corresponding to multiple services are not performed one by one, but the extreme values of the parameter information corresponding to these access types are compared. , find this extreme value and make a separate judgment, which can be the access type binding judgment result of multiple services.

For example, the access class is used as the decision parameter of the access control decision. The specific value of the access level is the aforementioned parameter information. Select the highest access level or the lowest access level among the multiple access levels to perform independent judgment on access control. If it is judged that the access is allowed, the binding judgment result is that the access is allowed. If it is determined that access is prohibited, the binding judgment result is access prohibited.

For another example, the access factor is used as the decision parameter of the access control decision, and the specific reference of the access factor is the aforementioned parameter information. For example, if there are multiple access factors, the maximum or minimum value of the access factors can be selected, compared with the random number generated randomly, and then a judgment result can be obtained according to the comparison result, and the judgment result will be regarded as the multiple access factors in this application. The binding judgment result of the access type corresponding to each service.

For another example, in the service priorities of multiple services that initiate access, the parameter information of the access type corresponding to the service with the highest service priority is selected as the target parameter information, and the binding judgment of the access types of the multiple services is performed. .

In a word, there are multiple ways to select one parameter information as the target parameter information from the multiple parameter information involved in different access types corresponding to multiple services, and the specific implementation is not limited to any one of the above.

In the embodiment of the present disclosure, in order to reduce unnecessary access, when selecting target parameter information participating in the decision, a value that makes the access control more strict will be selected. For example, if the access level is used as the decision parameter of the access control decision, the value of the access control partial strictness is: the minimum access level. If the access factor is used as the decision parameter of the access control decision, the minimum access factor is selected for one decision, and a binding decision result valid for access triggered by multiple services in the embodiment of the present disclosure is obtained.

In one embodiment, the AC decision rule further includes: a fourth decision rule.

According to the fourth decision rule, the S110 may include:

According to the fourth decision rule, in response to the different access types corresponding to the multiple services, the NAS layer sends the parameter information of each access type corresponding to the multiple services to the AS layer respectively; Different access types corresponding to the service, including: different single-modal access types and/or different multi-modal access types;

The AS layer makes a judgment according to the parameter information of the received access type, and obtains a judgment result;

According to the determined judgment results, the binding judgment results of the multiple services are predicted.

If multiple services correspond to multiple access types, the NAS layer of the UE may access the AS layer one by one. , the judgment is started immediately, and the binding judgment results of the multiple services can be obtained according to the determined one or more individual judgment results.

Assuming that there are currently M services in the UE that trigger the access, it is necessary to make a judgment on the access triggered by the M services. The parameter information of the access types of the P services has been sent from the NAS layer to the AS layer. At this time, The parameter information of the access type of the remaining MP services has not been sent. Both M and P here are positive integers, and M is greater than P.

In one case, after receiving the parameter information of the access types of the P services, the AS layer makes a separate judgment on one or more of the P services according to the parameter information of the access types of the P services to obtain the document judgment result. , and the binding judgment results of M services are predicted and obtained according to the P judgment results.

In another case, after receiving the parameter information of the access types of the P services, the AS layer makes a binding decision for the access initiated by the P services according to the parameter information of the access types of the P services, and obtains a result based on the P services. The binding judgment result of the service is determined, and then the final binding judgment result of the M services is determined according to the binding judgment result.

For example, when the NAS layer delivers the parameter information of the access types of multiple services to the AS layer, for example, priority is given to delivery from the beginning of the access level with high priority, etc. In short, the priority can be given to the degree of influence on the binding judgment result. The parameter information of the final access type starts to be issued. In this way, the AS layer will preferentially receive the parameter information of the access type that has a greater impact on the binding judgment result, and then start to make a separate judgment to obtain the independent judgment result; For an individual decision result that has a great influence on the binding decision result, the binding decision result may not be predicted in advance before the parameter information of all access types corresponding to multiple services is obtained.

The generation of the binding decision can also be considered to be determined according to the AS decision rule, and the AP decision rule corresponding to this method can be considered as a priority rule.

Of course, when the NAS layer transmits the parameter information of the access type to the AS layer one by one, it can be transmitted in any order, and it is not limited to be issued according to the influence weight on the binding judgment result.

In one embodiment, the method further includes:

After predicting the binding decision result, the AS layer sends a feedback notification to the NAS layer;

The NAS layer stops sending the parameter information of the remaining access types to the AS layer according to the feedback notification.

Through the reporting of the feedback notification, the NAS layer in the UE will stop sending the distribution of parameter information of the remaining access types; thus, unnecessary information exchange between the NAS layer and the AS layer is reduced.

In some embodiments, the method further includes:

In response to the different access types corresponding to the multiple services and the binding decision result being that access is prohibited, start the prohibition timers corresponding to the different single-modal access types corresponding to the multiple services;

The access initiated by the multiple services is prohibited from being initiated within the time period of the prohibition timer.

If the result of the binding judgment is access prohibition, the access prohibition time within which the prohibition timer is started will be entered.

At this time, since the access types corresponding to the multiple services are different, the prohibition timers may also be set differently. At this time, the extreme value of the prohibition timer durations corresponding to the access types corresponding to the multiple services can be selected for execution. Entry initiated by multiple services is prohibited.

The extreme value can be a minimum or maximum value.

In one embodiment, the method further includes:

In response to the different access types corresponding to the multiple services and the result of the binding decision being that access is prohibited, the AS layer notifies the NAS layer of the determined duration of the prohibition timer;

or,

In response to the different access types corresponding to the multiple services and the binding decision result being that access is prohibited, the AS layer notifies the NAS layer of the timing durations of the prohibition timers for the different access types.

In one embodiment, the AS layer determines the access prohibition, determines the duration of the access prohibition, and notifies the NAS layer of the corresponding timing duration, and the NAS layer finally controls the initiation of the access triggered by the service.

In another embodiment, the AS layer will notify the NAS layer of the timing lengths of the prohibition timers for different access types, respectively. In this way, the NAS layer can separately set the access triggers for each service according to the prohibition timers of different access types. Prohibited duration.

In another embodiment, after receiving the timing duration of the prohibition timers of different access types corresponding to multiple services, the NAS layer can select an extreme value or an average value, etc., to uniformly prohibit access initiated by multiple services Timing is timed.

In one embodiment, the method further includes:

In response to the result of the binding judgment being that the access is allowed, the initiated access request carries a cause indication that indicates the association with the multimodal service.

If the current binding judgment result is that the binding judgment result for multiple services under the multimodal service is access allowed, the access request carries a cause indication for the association of the multimodal service.

The reason indication may indicate that multiple services are allowed to initiate access at the same time, because these multiple services correspond to the same multimodal service and so on. Of course, this is only an example of the cause indication, and the specific implementation is not limited to this.

In one embodiment, the reason indicates specific carried content, including but not limited to at least one of the following:

Indication of multimodal services;

The business identity of the multimodal business;

Priority indication corresponding to multimodal services.

Through the above reason indication, the network side can distinguish the access response from the single-modal service when receiving the access, for example, respond to the access of the multi-modal service with a higher probability than the single-modal service. Or, respond to access of multi-modal services with a lower probability than single-modal services.

In one embodiment, the method further includes:

The AS layer obtains the AC decision rule.

The AC decision rule obtained by the AS layer can be imported by the NAS layer, or received from the AS layer on the network side, or pre-written into the communication protocol.

The AC decision rule here may be: one or more of the foregoing first decision rule to fourth decision rule.

For example, the AS layer acquires the AC decision rule, including at least one of the following:

receiving a NAS notification carrying the AC decision rule;

According to a pre-agreed agreement, determine the AC judgment rule;

The AC decision rule issued by the base station is received.

If the AS layer of the UE receives the NAS notification delivered by the core network, the NAS notification may carry the AC judgment rule, and the AC judgment rule may be the AC judgment rule delivered by the core network in this case.

The foregoing pre-rules include, but are not limited to, communication protocols, and may also include pre-negotiation between the UE and the base station, and/or pre-negotiation between the UE and the core network.

In some cases, the base station may dynamically determine the AC decision rule according to the current wireless condition and/or network load rate, etc., and deliver it to the UE.

In some embodiments, the AC decision rule is delivered to the AS layer before the NAS layer delivers parameter information that triggers the AS layer to perform AC decision;

or,

The AC decision rule is delivered to the AS layer when the NAS layer delivers parameter information that triggers the AC layer to make an AC decision.

There are actually many kinds of delivery of the AC decision rule. In one embodiment, for example, the NAS layer sends the AC decision rule to the AS layer before delivering the parameter information of the access type to the AS layer.

Multimodality (Modality) involves multiple sources or forms of information, for example, people have touch, hearing, sight and smell. The medium of information includes voice, video, text, etc. In order to perceive user input from multiple dimensions, there are many types and numbers of applications (Application, APP) and/or devices for multimodal information collection. For example, a device includes: multiple cameras, speakers, sensors, keyboards, fingerprint collectors, and so on. These devices for collecting multiple modal information can be used on the same device or across devices.

In a single-user single-device multi-modal scenario, for example, the user's video can be collected through the camera on the same handheld terminal, and the user's voiceprint can also be collected through the sensor on the mobile phone, that is, the information of two modalities can be obtained at the same time. . At this time, if the information of the two modalities is reported to the network, it needs to be reported in combination. At this time, if the data sets of the two modalities are out of sync, it will cause a sense of dizziness in the user experience. Therefore, even if the content acquired by the same user on the same collection terminal is integrated and presented, stricter time synchronization is usually required.

From the terminal side, the data sets of two different modalities appear to be two different services at the non-access stratum (Non Access Stratum, NAS) layer. If these two services need to be bound and initiated, the binding needs to be considered in the admission control part, that is, the AS layer needs to make a binding decision for multiple services of the NAS layer. In the current (Access control, ACl) mechanism, the NAS layer only provides an access category (Access category) to the AS layer, and after the introduction of multi-modality in the future, the NAS layer provides the AS layer with multiple services at the same time. Therefore, the existing AC mechanism needs to be enhanced.

For the application scenarios of newly added multi-modal services in the network, add bound access control (Access control, AC) processing.

The newly added application scenarios of multi-modal services add bound AC processing for multi-modal services.

The AS layer makes a decision based on the access type list information provided by the NAS;

As an embodiment: the access type in the access type list provided by the NAS may be an access type defined by an existing protocol;

In one embodiment, the AS layer makes a decision based on the AC decision rule and notifies the upper layer of the decision result;

In one embodiment, the AS layer makes a decision based on the AC decision rule and notifies the upper layer of the decision result. It can be based on the Access Category one by one decision principle, that is, each Access Category is decided according to the existing mechanism to obtain multiple decision results, and then the results are judged one by one. To merge or not to merge processing:

As an example: if the judgment result merging rule is an AND relationship, that is, after all Access categories in the Access category list information have made a judgment as passed, the AC judgment result is returned as passed, and the NAS is notified of the AC judgment result;

As an example: if the judgment result merging rule is an or relationship, that is, after one Access category in the Access category list information has been judged as passed, the AC judgment result is returned as passed, and the NAS AC judgment result is notified; (conveniently The agent understands that at this time, the NAS is notified of the judgment result of the Access category list, for example, the judgment results of N services are passed, and the judgment results of M services are not passed)

As an example: if the judgment result merging rule is set according to the principle of different levels, that is, there are some items of Access category in the Access category list information, after all the judgments are passed, the AC judgment result is returned, and the NAS AC judgment is notified. the result of;

It is worth noting that: the AC decision result is passed, which means that the subsequent RRC signaling process can be performed; otherwise, the subsequent RRC process cannot be initiated.

In one embodiment, the AS layer makes a decision based on the AC decision rule and notifies the decision result. The upper layer can bind the decision principle based on the Access category:

As an example: according to the most strict configuration among the N elements in the Access category list information, for example, its access factor (AC barring factor) is the minimum value of the configuration, that is, only one judgment is made, and the judgment is passed. Otherwise, it is not passed. In the case of not passing, the prohibition timer (ac-BarringTime) is the most strictly configured among the N elements. For example, its ac-BarringTime is the maximum value of the configuration.

In one embodiment, the AS layer makes a decision based on the AC decision rule notified by the NAS, or pre-agreed in the protocol or provided by the base station, and notifies the upper layer of the decision result;

As an embodiment: the AC decision rule provided by the base station may be notified to the user in advance through public signaling or dedicated signaling;

As an example: the AC decision rule provided by the NAS can be provided when the NAS sends a message to the AS to make an AC decision, or can be provided before this;

In one embodiment, the AS layer makes a decision based on the AC decision rule and notifies the upper layer of the decision result, which can inform the upper layer of the list of whether the subsequent Access category can be passed or not passed;

As an example: the NAS layer only provides AS one Access category1 to make a judgment, and after the judgment is passed, the AS layer notifies the NAS layer that the subsequent Access category2, Access category3... can be passed;

Specifically, after the NAS layer receives it, when the services corresponding to Access category2, Access category3... are triggered to the AS, the Access category will not be carried, that is, the AC control of the AS layer will not be triggered, that is, it can be directly initiated. This method can reduce the delay, which is equivalent to making an early decision.

If the access control result is not allowed after the access control, the NAS can optionally notify the NAS layer of the barring timer (Barring timer) of the AS when notifying the NAS of the result of the AC decision, and notify the upper layer of the time when the lower layer is blocked, so that the upper layer can A reference to re-initiate the call at the appropriate time.
