DETAILED DESCRIPTION

The technical schemes in the embodiments of the present disclosure will now be described in conjunction with the accompanying drawings in the embodiments of the present disclosure. It will be apparent that the described embodiments are only part of the embodiments of the present disclosure, not all embodiments. Basing on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skilled in the art without making creative work are within the scope of the present disclosure.

With respect to a NR (New Radio) system for 5G networks, which has a QoS (Quality of Service) architecture as shown in FIG. 1. A core network establishes at least one PDU (Protocol Data Unit) session for each user equipment. An access network establishes one or more data radio bearer (DRB) for each PDU session, and establishes at least one default DRB for each PDU session established by the core network. The access network maps packets belonging to different PDU sessions to different DRBs. The non-access layer packet filters of the user equipment and the core network associate the uplink and downlink packets with a QoS flow. The access layer in the user equipment and the access network implement a mapping relation between the data radio bearer (DRB) as well as the uplink and downlink QoS flow. Where, in the downlink, the access network maps the QoS flow to the DRB according to a QoS flow ID and an associated QoS configuration file； in the uplink, the user equipment utilizes the QoS flow ID to perform an uplink grouping. In the NR system, the QoS flow is the most basic QoS granularity. Therefore, the system can perform an access control basing on the QoS flow ID in order to prevent overload and ensure the service quality.

Referring to FIG. 2, a flow chart of a first embodiment of an access control method according to the present disclosure is depicted. As shown in FIG. 2, an execution main body of the first embodiment of the access control method of the present disclosure is a user equipment. The user equipment may be fixed or portable, and may be a cell phone, a personal digital assistant (PDA) , a desktop computer, a tablet computer, a notebook computer, a cordless telephone, or the like. The method may include the following blocks.

At S11: receiving a downlink message from a base station through an user equipment, where the downlink message includes an access control mapping relationship, the access control mapping relationship includes a mapping relationship between an access parameter and an access category.

Where, the downlink message may be a radio resource control message or a system broadcast message, or other type of message, and the access category may be pre-defined, the amount of the access categories and the specific access category may be defined basing on actual needs, which is not specifically limited herein.

The access parameter is a relevant parameter required for the user equipment to perform an access decision, which includes a QoS flow ID and /or at least one auxiliary factor. Where, the auxiliary factor is a status parameter of the user equipment itself, which includes at least one of a priority, a call type, a service category, and a roaming status of the user equipment, and may include other parameters related to the user equipment, which is not specifically limited herein.

Specifically, in an application case, as shown in FIG. 3, the base station maps the QoS flow ID (QFI) and the access category (AC) corresponded by at least one existing QoS flow, thereby generating the access control mapping relationship. Where, the base station can map the QFI corresponded by a same type of QoS flow to a same AC basing on an operator's strategy, for example, mapping the data flow of a video service to the same AC, and so on. The base station may send the downlink message to the user equipment according to its own load condition so as to update the access control mapping relationship. The base station may send the downlink message to the user equipment through broadcast manner, or may send the downlink message to the user equipment through a certain idle channel, which is not specifically limited herein. In other application cases, the access parameter may also only include at least one auxiliary factor, and the base station may map at least one auxiliary factor, such as the user equipment priority of 1 and the service category of video, to an access category 2.

Of course, in other embodiments, the base station may also perform mapping basing on other mapping criteria, for example, mapping the QFI corresponded by the QoS flow with a same QoS requirement to a same AC, or the like, and when the base station generates the access control mapping relationship, other factors (metrics) such as the roaming status and the priority of the user equipment can also be considered, or a traffic category (TC) can be added to map the QFI to the TC first, and then map the TC to the AC, which is not specifically limited herein.

At S12: matching the access category corresponded by the access parameter of an uplink message to be sent in the access control mapping relationship.

In the NR system, for the uplink, the user equipment can utilize an uplink reflective QoS mapping to obtain the same QoS flow ID as the downlink, that is, the user equipment monitors the QoS flow ID of the downlink and applies the same mapping in the uplink, for each DRB.

Specifically, in an application case, the user equipment can be in an idle status, in which the downlink message is received when it is ready to send a service request to the base station, or the downlink message may be received after the connection with the base station becomes successful. As shown in FIG. 3, after the user equipment receives the downlink message, the QFI in the downlink message is obtained, which can be mapped to the uplink message to be sent, where the QFI of the uplink message to be sent is the same as the QFI of the downlink message. Before the user equipment sends the uplink message to the base station, for example, when sending the service request message to the base station, the access category corresponded by the QFI of the uplink message in the access control mapping relationship is searched first, that is, the AC having the mapping relationship with the QFI of the uplink message is searched. If the matching AC is searched out, the subsequent access control steps are performed； if the matching AC is not searched out, the sending of the uplink message is directly restricted, and to wait the base station to update the access control mapping relationship. Of course, in other application cases, if the matching AC is not searched out, the user equipment can directly map the QFI to the AC of the lowest priority, or map to a certain AC and utilize the AC to perform the subsequent access control operation, which is not specifically limited herein.

In other embodiments, the user equipment may also randomly assign a QFI to the uplink message to be sent, which is not specifically limited herein.

In another application case, when the access parameter only includes at least one auxiliary factor, for example, when the priority of the user equipment is 1 and the service category is video, the corresponding access category is the access category 2. When the uplink message to be sent of the user equipment is a video message, and the priority of the user equipment is 1, the user equipment can obtain that the access category of 2 which matches the access parameter of the uplink message to be sent in the access control mapping relationship. Of course, in other application cases, the access parameter may also include a combination of a QoS flow ID and at least one auxiliary factor, which is not specifically limited herein.

At S13: performing an access control utilizing the access category obtained by matching.

Specifically, in an application case, different access categories has different access possibilities, the access categories with higher priority are more likely to be accessed and can be accessed with priority, and the access categories with lower priority are more difficult to be accessed. When the load of the base station is heavy, it can map more QoS flow IDs to the access categories of low priorities, thereby realizing the access control and avoiding the heavy load. When the load of the base station is light, it can map more QoS flow IDs to the access categories of high priorities, thereby improving the resource utilization. The user equipment can directly set a part of the access categories with higher priority to not barred (allowed access) , and set the other part of the access categories with lower priority to barred (restricted access) , for example, allowing the uplink message corresponded by the first five access categories to access, and restricting the uplink message corresponded by the remaining five access categories to access. Of course, the user equipment can also utilize other methods such as calculating the access probability to perform the access control, which is not specifically limited herein.

In this embodiment, the user equipment receives the downlink message from the base station, where the downlink message includes the access control mapping relationship including a mapping relationship between the access parameter and the access category. In the access control mapping relationship, the access category corresponded by the access parameter of the uplink message to be sent is matched, and the access control is performed utilizing the access category obtained by matching. As a result, the user equipment can perform the access control by merely obtaining the access category corresponded by the uplink message to be sent in the access control mapping relationship. As the access control mapping relationship is considered unifiedly by the base station, the embodiment of the present disclosure could reduce the burden of the user equipment and improve the access control efficiency, which can be applied to the idle status and a connected status of the user equipment, while having a wide application scope and a high compatibility.

Referring to FIG. 4, a flow chart of a second embodiment of an access control method according to the present disclosure is depicted. As shown in FIG. 4, the second embodiment of the access control method of the present disclosure is based on the first embodiment of the access control method of the present disclosure. Block S12 may further include the following block.

At S121: searching the access category having a mapping relationship with the QoS flow ID and /or at least one auxiliary factor of the uplink message to be sent in the access control mapping relationship.

Where, when the user equipment generates the uplink message to be sent, the QoS flow ID of the uplink message can be obtained by mapping the QoS flow ID of the uplink, or can be a QoS flow ID generated randomly by the user equipment, which is not specifically limited herein. The auxiliary factor is the status parameter of the user equipment itself, which includes at least one of a priority, a call type, a service category, and a roaming status of the user equipment, and may include other parameters related to the user equipment, which is not specifically limited herein.

The access parameter includes a QoS flow ID and /or at least one auxiliary factor, and the access control mapping relationship includes at least one of a mapping relationship between a QoS flow ID and an access category, a mapping relationship between at least one auxiliary factor and an access category, and a mapping relationship between a combination of a QoS flow ID and at least one auxiliary factor as well as an access category.

Specifically, in an application case, as shown in FIG. 5, the access control mapping relationship includes a mapping relationship between at least one QoS flow ID (QFI) and an access category, a mapping relationship between at least one auxiliary factor (other metric) and an access category, and a mapping relationship between a combination of at least one QoS flow ID and at least one auxiliary factor as well as an access category. After the user equipment obtains the QoS flow ID and /or at least one auxiliary factor of the uplink message to be sent, the access category to which the QoS flow ID and /or at least one auxiliary factor maps is searched in the access control mapping relationship.

For instance, when the QoS flow ID of the uplink message to be sent which is obtained by the user equipment is 0x1a, it can be searched out that the access category to which 0x1a maps is the access category 1, according to an access control mapping relationship table of FIG. 5. When the QoS flow ID of the uplink message to be sent which is obtained by the user equipment is 0x2a and the priority of the user equipment is 1, it can be searched out that an access category to which a combination of 0x2a and the priority 1 (UE Category ＝ 1) of the user equipment maps is an access category 2, according to the access control mapping relationship table of FIG. 5. When the uplink message to be sent which is obtained by the user equipment is a video service flow and the priority of the user equipment is 2, it can be searched out that an access category to which the video service flow (Service ＝ video) and the priority 2 (UE Category ＝ 2) of the user equipment maps is an access category 4.

Of course, in other application cases, the access control mapping relationship may also only include a mapping relationship between a QoS flow ID and an access category, or only include a mapping relationship between a combination of a QoS flow ID and at least one auxiliary factor as well as an access category, which is not specifically limited herein.

In this embodiment, when the user equipment performs the access control, the status of the user equipment is also considered, for example, distinguishing between roaming and non-roaming user equipment, etc., which has a wider application scope and is more efficient in the access control.

Referring to FIG. 6, a flow chart of a third embodiment of an access control method according to the present disclosure is depicted. As shown in FIG. 6, the third embodiment of the access control method of the present disclosure is based on the second embodiment of the access control method of the present disclosure. Block S12 may further include the following block.

At S122: mapping the QoS flow ID and /or at least one auxiliary factor to the access category of the lowest priority through the user equipment, when an access category matching the QoS flow ID and /or at least one auxiliary factor in the access control mapping relationship is not searched out.

Specifically, in an application case, after the user equipment obtains the QoS flow ID of the uplink message to be sent, and the access category matching the QoS flow ID is not searched out in the access control mapping relationship, the QoS flow ID can be directly mapped to the access category of the lowest priority, so that the access control operation can be performed by utilizing the access category of the lowest priority, thereby saving the waiting time. In other application cases, the user equipment may also send the updated access mapping relationship to the base station, so that the base station can update the data. In other application cases, when the user equipment does not search out an access category matching the at least one auxiliary factor in the access control mapping relationship, or does not search out an access category matching a combination of the QoS flow ID and at least one auxiliary factor, the user equipment may map the at least one auxiliary factor or a combination of the QoS flow ID and at least one auxiliary factor to the access category of the lowest priority.

Of course, in other embodiments, when the user equipment does not search out a matching access category in the access control mapping relationship, the user equipment may suspend the sending of the uplink message and wait for the base station to update the access control mapping relationship, and the user equipment may also map the QoS flow ID which does not match to an access category to any access category, which is not specifically limited herein.

Referring to FIG. 7, a flow chart of a fourth embodiment of an access control method according to the present disclosure. As shown in FIG. 7, the fourth embodiment of the access control method of the present disclosure is based on the first embodiment of the access control method of the present disclosure. Block S12 may further include the following blocks.

At S123: searching a service category having a mapping relationship with the QoS flow ID and /or at least one auxiliary factor of the uplink message to be sent in the access control mapping relationship.

Where, when the user equipment generates the uplink message to be sent, the QoS flow ID of the uplink message can be obtained by mapping the QoS flow ID of the uplink message, or a QoS flow ID generated randomly by the user equipment, which is not specifically limited herein. The access control mapping relationship at least includes a mapping relationship between a QoS flow ID and /or at least one auxiliary factor and the service category.

Specifically, in an application case, as shown in FIG. 8, the access control mapping relationship includes a mapping of at least one QoS flow ID and a service (traffic) category, and a mapping of at least one service category and an access category. After the user equipment obtains the QoS flow ID of the uplink message to be sent, the service category to which the QoS flow ID maps is searched in the access control mapping relationship.

For instance, when the QoS flow ID of the uplink message to be sent which is obtained by the user equipment is 0x2a, it can be searched out that an access category to which 0x2a maps is an access category 3, according to an access control mapping relationship table of FIG. 8.

Of course, in other application cases, the access parameter may only include at least one auxiliary factor, and the access control mapping relationship may also only include a mapping relationship between at least one auxiliary factor and a service category, and a mapping relationship between a service category and an access category, which is not specifically limited herein.

S124: matching the access category corresponded by the service category in the access control mapping relationship.

In the above-mentioned application case, as shown in FIG. 8, after the user equipment searches out the service category to which the QoS flow ID maps in the access control mapping relationship, it continues to search the access category having the mapping relationship with the service category in the access control mapping relationship.

For instance, when the service category searched out by the user equipment according to the access control mapping relationship table of FIG. 8 is the service category 2, the access category mapped by the service category 2 which can be searched out according to the access control mapping relationship table again is the access category 1.

In other application cases, the access control mapping relationship further includes a mapping relationship between a combination of a service category and at least one auxiliary factor as well as an access category.

Optionally, as shown in FIG. 9, block S124 includes the following block.

At S1241: searching the access category having the mapping relationship with the service category and /or at least one auxiliary factor in the access control mapping relationship.

Specifically, in the above-mentioned application case, as shown in FIG. 8, the access control mapping relationship includes a mapping of at least one QoS flow ID and one service category, and a mapping of a combination of at least one service category and at least one auxiliary factor as well as one access category. After the user equipment searches out the service category to which the QoS flow ID of the uplink message to be sent maps, it searches an access category to which the service category maps in the access control mapping relationship, or searches an access category to which a combination of the service category and at least one auxiliary factor maps.

For instance, when the service category searched out by the user equipment according to the access control mapping relationship table of FIG. 8 is the service category 3, and the priority of the user equipment is 1, which can search out that the access category to which a combination of the service category 3 and the priority 1 (UE Category ＝ 1) of the user equipment maps is the access category 2, according to the access control mapping relationship table of FIG. 8.

Of course, in other application cases, the access control mapping relationship may only include a mapping relationship between a QoS flow ID and a service category, and a mapping relationship between a service category and an access category； or only include a mapping relationship between a QoS flow ID and a service category, and a mapping relationship between a combination of a service category and at least one auxiliary factor as well as an access category； or only include a mapping relationship between at least one auxiliary factor and a service category, and a mapping relationship between a service category and /or at least another auxiliary factor as well as an access category, which is not specifically limited herein.

In this embodiment, a QoS flow ID and /or at least one auxiliary factor is mapped to a service category first, and more QoS flow IDs and /or auxiliary factors can be mapped to fewer service categories, thereby reducing the subsequent mapping relationship with respect to the access category and reducing the difficulty of the user equipment to search the mapping relationship so as to improve the efficiency of search.

Referring to FIG. 10, a flow chart of a fifth embodiment of an access control method according to the present disclosure is depicted. As shown in FIG. 10, the fifth embodiment of the access control method of the present disclosure is based on the fourth embodiment of the access control method of the present disclosure. Block S12 may further include the following block.

At S125: mapping the QoS flow ID and /or at least one auxiliary factor to the service category of the lowest priority through the user equipment, when a service category having a mapping relationship with the QoS flow ID and /or at least one auxiliary factor does not searched out in the access control mapping relationship.

Specifically, in an application case, after the user equipment obtains the QoS flow ID of the uplink message to be sent, and the service category matching the QoS flow ID is not searched out in the access control mapping relationship, the QoS flow ID can be directly mapped to the service category of the lowest priority, so that the access control operation can be performed by utilizing the access category corresponded by the service category of the lowest priority, thereby saving the waiting time. In other application cases, the user equipment may also send the updated access mapping relationship to the base station, so that the base station can update the data. In other application cases, the user equipment may map at least one auxiliary factor which does not match to a service category to a service category of the lowest priority, or map a QoS flow ID and at least one auxiliary factor which do not match to a service category to a service category of the lowest priority, which is not specifically limited herein.

Of course, in other embodiments, if the user equipment does not search out a matching service category in the access control mapping relationship, the user equipment may suspend the sending of the uplink message and wait for the base station to update the access control mapping relationship, and the user equipment may also map the QoS flow ID which does not match to a service category to any service category, which is not specifically limited herein.

Referring to FIG. 11, a flow chart of a sixth embodiment of an access control method according to the present disclosure is depicted. As shown in FIG. 11, the sixth embodiment of the access control method of the present disclosure is based on the first embodiment of the access control method of the present disclosure. Block S13 may include the following blocks.

At S131: performing a barring check to the uplink message to obtain an access probability of the uplink message.

Where, a barring check method which has a same formula with the ACDC mechanism of the LTE system can be adopted as the barring check, and other barring check method can also be adopted, which is not specifically limited herein.

Specifically, in an application case, the user equipment randomly generates a random number between 0-1 utilizing a random function, takes the random number as the access probability of the uplink message, in which the random function can be an even distributed random function between 0-1, and can be other type of random function, which can be specifically set basing on different access categories, and is not specifically limited herein.

At S132: determining whether the access probability is greater than an access probability threshold.

At S133: allowing the sending of the uplink message when the access probability is greater than the access probability threshold.

In the above-mentioned application case, the downlink message further includes an access control parameter at least including the access probability threshold corresponded by each access category； where, the access categories of the higher priorities correspond to the lower access probability thresholds, which have higher access probabilities. After the user equipment obtains the access probability (e.g., 0.5) of the uplink message, the access probability threshold (e.g., 0.3) corresponded by the access category can be obtained through the access category obtained by the previous matching. The access probability and the access probability threshold are compared, and when the access probability is greater than the access probability threshold (e.g., 0.5 is greater than 0.3) , the uplink message is allowed to send, and the user equipment can send the uplink message to the base station, that is, a service request can be initiated, or the sending of communication data to the base station may be continued.

Specifically, in an application case, each access category corresponds to an individual access waiting time, and the access waiting time of the access category of a higher priority is less than the access waiting time of the access category of a lower priority. An access waiting timer corresponded by the access category of the uplink message is enabled while the user equipment restricts the sending of the uplink message to be sent. When the timing value of the access waiting timer is smaller than the access waiting time corresponded by the access category, the user equipment does not initiate the same service request, and when the timing value of the access waiting timer is equal to the access waiting time corresponded by the access category, the user equipment can initiate the same service request and clear the timing value of the access waiting timer simultaneously.

Of course, in other embodiments, the access waiting timer may not be cleared, instead, the differentiate between the current timing value and the initial timing value as well as the access waiting time can be compared in the next timing process. In addition, the access waiting time of each access category can also be changed according to actual needs, which is not specifically limited herein.

Referring to FIG. 15, a flow chart of a ninth embodiment of an access control method according to the present disclosure is depicted. As shown in FIG. 15, the ninth embodiment of the access control method of the present disclosure is based on the seventh embodiment of the access control method of the present disclosure.

When the user equipment allows the sending of the uplink message to be sent, the access status corresponded by the access category which matches a QoS flow ID of the uplink message is set to the not barred status. When the user equipment restricts the sending of the uplink message to be sent, the access status is set to the barred status.

Specifically, in an application case, the user equipment generates the mapping matrix. As shown in FIG. 16, the mapping matrix includes an access category and an access status corresponded by each access category, in which the access status includes a not barred status (Not barred) , a barred status (Barred) , and an unknown status (N/A) . In an initial status, the user equipment generates the access category included in the access control mapping relationship and the access status corresponded by the access category, according to the received access control mapping relationship. Where, in the initial status of the access status, i.e., the initial access status, may set to the unknown status (N/A) . After the user equipment performs the barring check to the uplink message to be sent, the access status corresponded by the access category matched by the QoS flow ID of the uplink message is set to the not barred status while the uplink message is allowed to be sent, and the access status corresponded by the access category matched by the QoS flow ID is set to the barred status while the user equipment restricts the sending of the uplink message.

Where, the user equipment may restrict the sending of the uplink message by temporarily storing the uplink message in the buffer and resending after waiting for the access status to become to the not barred status, or by discarding the uplink message directly, which is not specifically limited herein.

Specifically, when the user equipment is in the connected status, the access category matching the QoS flow ID can be searched out by utilizing the access control mapping relationship after the user equipment obtains the QoS flow ID of the uplink message to be sent. Thereafter, the access status corresponded by the access category can be obtained directly from the stored mapping matrix. When the access status is the not barred status, the user equipment sends the uplink message to the base station. When the access status is the barred status, the user equipment restricts the sending of the uplink message, thereby avoiding the overload of the base station due to the excessive data sending by the user equipment.

In this embodiment, when the user equipment is in the connected status, the access status is directly obtained from the mapping matrix for access control, and it is not necessary to repeat the barring check for each uplink message, which reduces the calculations of the user equipment, reduces the burden of the user equipment, and improves the access control efficiency.

In other embodiments, when the user equipment is in the connected status, it is also possible to perform the access control by adopting the method of performing the barring check for each uplink message, which is not specifically limited herein.

The execution of the blocks of this embodiment may be performed after block S14.

Referring to FIG. 18, a flow chart of an eleventh embodiment of an access control method according to the present disclosure is depicted.

Specifically, as shown in FIG. 19, the mapping matrix stored by the user equipment further includes a timeout period of each access status, and the access status needs to be updated when the duration of each access status reaches the timeout period of the access status. The timeout period of each access status can be set according to actual needs, which is not specifically limited herein.

S142: setting the access status to the unknown status when the duration of the access status is greater than the update period of the access status.

Specifically, when the user equipment sets each access status to the not barred /the barred status, as Not Barred/Barred status shown in FIG. 19, a timer is enabled. When the value of the timer is greater than the timeout period (e.g., 30 minutes) of the access status, which indicates that the duration of the access status needs to be updated, and the user equipment sets the access status to the unknown status, as N/Astatus shown in FIG. 19, so as to perform the barring check subsequently to realize the status update with respect to the next uplink message to be sent.

Of course, in other embodiments, the user equipment may also set the access status to null or clear the access status when the duration of the access status is greater than the timeout period of the access status, and the access status of the changed access category may also be set to the unknown status when the user equipment receives a message of updating the access control mapping relationship which is sent by the base station, which is not specifically limited herein.

Specifically, in an application case, when the user equipment is in the connected status, after the access category matching the QoS flow ID of the uplink message to be sent is obtained, and the access status corresponded by the access category obtained by matching which is searched out from the mapping matrix is the unknown status, the user equipment needs to perform the barring check to the uplink message. When the uplink message is allowed to be sent, the access status of the access category obtained by matching in the mapping matrix is set to the not barred status. When the sending of the uplink message is restricted, the access status of the access category obtained by matching is set to the barred status, thereby realizing the update of the access status in the mapping matrix.

This embodiment may also be combined with any of the sixth, the ninth, and the eleventh embodiments of the access control method of the present disclosure or their non-conflicting combination.

Referring to FIG. 21, a flow chart of a thirteenth embodiment of an access control method according to the present disclosure is depicted. As shown in FIG. 21, an execution main body of the thirteenth embodiment of the access control method of the present disclosure is a base station. The base station is connected to the core network and performs wireless communication with the user equipment, and provides communication coverage for a corresponding geographical area. The base station may be a macro base station, a micro base station, a pico base station, or a femtocell.

The access parameter includes a QoS flow ID and /or at least one auxiliary factor, where the auxiliary factor is a status parameter of the user equipment itself, which includes at least one of a priority, a call type, a service category, and a roaming status of the user equipment, and may include other parameters related to the user equipment, which is not specifically limited herein.

Specifically, in an application case, as shown in FIG. 3, the base station maps a QoS flow ID (QFI) and an access category (AC) corresponded by at least one existing QoS flow, thereby generating the access control mapping relationship. Where, the base station can map the QFI corresponded by a same type of QoS flow to a same AC basing on an operator's strategy such as mapping the data flow of a video service to the same AC. The base station may send the downlink message to the user equipment according to its own load condition so as to update the access control mapping relationship. In other application cases, the access parameter may also only include at least one auxiliary factor, and the base station may map at least one auxiliary factor such as the user equipment priority of 1 and the service category of video, to the access category 2.

Of course, in other embodiments, the base station may also perform mapping basing on other mapping criteria, for example, mapping the QFI corresponded by the QoS flow with a same QoS requirement to a same AC, and so on, and when the base station generates the access control mapping relationship, other metrics such as roaming status, priority, etc. of the user equipment can also be considered, or a Traffic Category (TC) can be added to map the QFI to the TC first, and then map the TC to the AC, which is not specifically limited herein.

Where, the downlink message may be a radio resource control message or a system broadcast message, or other type of message, and the access category may be pre-defined, the amount of access categories and the specific access category may be defined basing on actual needs, which is not specifically limited herein.

Specifically, as shown in FIG. 3, the base station may send the downlink message to the user equipment in a broadcast manner, or may send the downlink message to the user equipment through a certain idle channel, which is not specifically limited herein. After the user equipment receives the downlink message of the base station, and before sending the uplink message to the base station, for instance, when sending the uplink message of a service request, it searches the access category corresponded by the QFI of the uplink message in the access control mapping relationship first, that is, searching the AC having the mapping relationship with the QFI of the uplink message, and performing the subsequent access control blocks when the matching AC is searched out. The specific access control block may refer to the first to the twelfth embodiments of the access control method of the present disclosure, which is not repeated herein.

In this embodiment, the base station generates the access control mapping relationship, and sends the access control mapping relationship to the user equipment so that the user equipment can perform an access decision basing on the access control mapping relationship and execute the corresponding access control. The user equipment can perform the access control by merely obtaining the access category corresponded by the uplink message to be sent in the access control mapping relationship. As the access control mapping relationship is considered unifiedly by the base station, the embodiment of the present disclosure could reduce the burden of the user equipment and improve the access control efficiency, which can be applied to the idle status and the connected status of the user equipment, while having a wide application scope and a high compatibility.

As shown in FIG. 5, the base station may map at least one QoS flow ID to an access category, for example, mapping 0x1a, 0x1b, and 0x1c to the access category 1, and the base station may further map a combination of at least one QoS flow ID and at least one auxiliary factor to an access category, for example, mapping 0x3a, 0x4d, and a non-roaming user equipment (non-roaming UE) to the access category 3.

Of course, in other application cases, when the base station generates the access control mapping relationship, it is possible to generate only a mapping relationship between a QoS flow ID and an access category, or only a mapping relationship between a combination of a QoS flow ID and at least one auxiliary factor as well as an access category, or only generate a mapping relationship between at least one auxiliary factor and an access category, which is not specifically limited herein.

In other application cases, the core network device may map at least one auxiliary factor to a service category. For example, as shown in FIG. 26, the service category of video (Service ＝video) is mapped to a service category 5, and the mapping relationship is sent to the base station, which is not specifically limited herein.

In this embodiment, the core network device completes a mapping relationship between a QoS flow ID and /or at least one auxiliary factor as well as a service category in advance and sends it to the base station. When the base station receives the mapping relationship, the access control mapping relationship can be generated by merely generating a mapping relationship between a service category and an access category, thereby reducing the burden on the base station.
