Optionally, as another embodiment, the identification information of an application that is allowed to access the network is classified identification information of the application that is allowed to access the network, or the identification information of an application that is prohibited from accessing the network is classified identification information of the application that is prohibited from accessing the network, and correspondingly, the access control information may include classified control information. The determining, according to the application configuration new information and the access control information, whether to allow an application of the user equipment to access the network includes: determining, according to the application configuration information and the classified control information, whether to allow the application of the user equipment to access the network.

Further, the access control information may further include the user equipment control information. In this case, the determining, according to the application configuration information and the classified control information, whether to allow the application of the user equipment to access the network includes: determining, according to a class of the user equipment, the user equipment class control information, the application configuration information, and the classified control information, whether to allow the application of the user equipment to access the network.

Send access control information to user equipment, where the access control information is classified control information and/or user equipment class control information, the classified control information is used to control a category of an application that accesses the network, and the user equipment class control information is used to control a class of user equipment that accesses the network and instruct the user equipment to use application configuration information.
The access control information may be sent to the user equipment by the access network device in a broadcast manner. For user equipment in connected mode, the access network device may send the access control information to the user equipment by using dedicated signaling.
According to the embodiment shown in
Specifically, in a case in which congestion occurs on the core network, the access control information may be determined according to an access reference indicator that is received from a core network device. In a case in which congestion occurs on the access network, the access control information may be determined according to a congestion degree of the access network. The access network device may determine, in a case in which a radio resource is insufficient, that congestion occurs on the access network, or determine, in a case in which a central processing unit, a memory, or the like is occupied to a great extent, that congestion occurs on the access network.
Specifically, the classified control information includes any one of the following: priority information, congestion degree information, and group information of the application. For a method for using each type of classified control information, reference may be made to the corresponding description in the embodiment shown in
301. Determine application configuration information, where the application configuration information includes identification information of an application that is allowed to access a network or identification information of an application that is prohibited from accessing a network.
Specifically, the identification information may be an identifier of a specific application (for example, WeChat), or may be a company to which an application belongs, or may be an attribute of an application (for example, a video application, an instant messaging application, or a news application), or the like. Further, the identification information of an application that is allowed to access the network may further be classified identification information of an application that is allowed to access a network, or classified identification information of an application that is prohibited from accessing a network. Identification information of an application may be classified by using a priority, a congestion degree, and an application group. The identification information and a classification manner in the application configuration information are set on the side of the core network device in a preset manner. In other words, the application configuration information is determined by the core network device in preset configuration. In addition, the classification manner in the application configuration information is in a one-to-one correspondence with category in classified control information sent by an access network device. For example, if the identification information of the application is classified by using a priority, the classified control information is priority information.
302. Send the application configuration information to user equipment.
Specifically, the application configuration information may be sent to the user equipment by using Open Mobile Alliance Device Management (OMA DM), or may be sent to the user equipment by using non-access stratum (NAS) signaling.
According to the embodiment shown in
Optionally, as an embodiment, the method further includes: determining an access reference indicator, where the access reference indicator includes user equipment class reference information, and the user equipment class reference information is used to provide reference information for controlling a class of user equipment that accesses the network; and sending the access reference indicator to an access network device. The access reference indicator is determined by the core network device according to a congestion degree of a core network. For example, the core network device may determine, in a case of high usage of a central processing unit, a memory, or the like, that congestion occurs. The access reference indicator may be sent to the access network device by using control-plane signaling (which may be, for example, control-plane signaling through an S1 interface).
Optionally, as another embodiment, the identification information of an application that is allowed to access the network is classified identification information of the application that is allowed to access the network, or the identification information of an application that is prohibited from accessing the network is classified identification information of the application that is prohibited from accessing the network; and the method further includes: determining an access reference indicator, where the access reference indicator includes classified reference information, or the access reference indicator includes classified reference information and user class reference information, the classified reference information is used to provide reference information for controlling a category of an application that accesses the network, and the user equipment class control information is used to provide reference information for controlling a class of user equipment that accesses the network; and sending the access reference indicator to an access network device. The access reference indicator is determined by the core network device according to a congestion degree of a core network. The access reference indicator may be sent to the access network device by using control-plane signaling (which may be, for example, control-plane signaling through an S1 interface).
401. A core network device determines application configuration information, where the application configuration information includes identification information of an application that is allowed to access a network or identification information of an application that is prohibited from accessing a network, the identification information of an application that is allowed to access the network may also be referred to as an application whitelist, and the identification information of an application that is prohibited from accessing the network may also be referred to as an application blacklist.
Specifically, the identification information may be an identifier of a specific application (for example, WeChat), or may be a company to which an application belongs, or may be an attribute of an application (for example, a video application, an instant messaging application, or a news application), or the like.
Further, the identification information of an application that is allowed to access the network may further be classified identification information of an application that is allowed to access a network, or classified identification information of an application that is prohibited from accessing a network. Identification information of an application may be classified by using a priority, a congestion degree, and an application group. For example, Table 1 shows a specific example in which identification information of an application that is allowed to access a network is classified according to a priority. It should be noted that the example in Table 1 is only for the purpose of helping to better understand the present application, and does not intend to limit the present application.
As can be seen from Table 1, priority 1 corresponds to an application whose identification information is A, priority 2 corresponds to the application whose identification information is A and an application whose identification information is B, and priority 3 corresponds to the application whose identification information is A, the application whose identification information is B, and an application whose identification information is C.
Table 2 shows a specific example in which identification information of an application that is allowed to access a network is classified according to a congestion degree. It should be noted that the example in Table 2 is only for the purpose of helping to better understand the present application, and does not intend to limit the present application.
As can be seen from Table 2, a congestion degree level 1 corresponds to an application whose identification information is A, a congestion degree level 2 corresponds to an application whose identification information is B, and a congestion degree level 3 corresponds to an application whose identification information is C, where the level 1 indicates that a network congestion degree is high, the level 2 indicates that a network congestion degree is medium, and the level 3 indicates that a network congestion degree is low.
Table 3 shows a specific example in which identification information of an application that is allowed to access a network is classified according to an application group. It should be noted that the example in Table 3 is only for the purpose of helping to better understand the present application, and does not intend to limit the present application.
As can be seen from Table 3, an application whose identification information is A belongs to a group 1, a group 2, and a group 3, an application whose identification information is B belongs to the group 2 and the group 3, and an application whose identification information is C belongs only to the group 3.
402. The core network device sends the application configuration information to user equipment. The application configuration information may be sent to the user equipment by using Open Mobile Alliance Device Management (OMA DM), or may be sent to the user equipment by using non-access stratum (NAS) signaling. Specifically, the application configuration information is sent to a protocol stack upper layer of the user equipment, and the protocol stack upper layer includes an application layer and a non-access stratum.
It may be understood that the application configuration information may also be preset in the user equipment. In this case, step 401 and step 402 do not need to be performed. The user equipment may acquire the application configuration information by directly reading the preset application configuration information.
Step 403 and step 404 are optional steps, and are performed in a case in which congestion occurs on a core network.
403. The core network device determines an access reference indicator according to a congestion degree of a core network.
Optionally, as an embodiment, the access reference indicator may include user class reference information, and the user class reference information is used to provide reference information for controlling a class of user equipment that accesses the network. Specifically, the user equipment class reference information may provide a reference class of user equipment that is allowed to access a network, or a reference class of user equipment that is prohibited from accessing a network.
Optionally, as another embodiment, in a case in which the application configuration information includes classified identification information of the application that is allowed to access the network or classified identification information of the application that is prohibited from accessing the network, the access reference indicator may include classified reference information, where the classified reference information is used to provide reference information for controlling a category of an application that accesses the network. For example, the classified reference information may include: a reference priority, a reference congestion degree, or a reference user group. Specifically, if identification information of an application is classified according to a priority, the classified reference information is a reference priority. In the example in Table 1, the classified reference information may include the priority 1, the priority 2, and the priority 3. If identification information of an application is classified according to a congestion degree, the classified reference information is a reference congestion degree. In the example in Table 2, the classified reference information may include the level 1, the level 2, or the level 3. If identification information of an application is classified according to an application group, the classified reference information is a reference application group. In the example in Table 3, the classified reference information includes the group 1, the group 2, and the group 3. Further, the access reference indicator may further include user equipment class reference information, that is, the access reference indicator includes user equipment class reference information and classified reference information.
404. The core network device sends the access reference indicator to an access network device. In a case in which the access network device receives the access reference indicator sent by the core network device, the access network device determines that congestion occurs on the core network.
405. The access network device determines access control information. Specifically, in a case in which step 403 and step 404 are performed, the access network device determines the access control information with reference to the access reference indicator. Alternatively, in a case in which step 403 and step 404 are not performed, the access network device may determine the access control information according to a congestion degree of an access network.
Optionally, as an embodiment, the access control information may include user class control information, where the user class control information is used to control a class of user equipment that accesses the network and instruct the user equipment to determine, according to the application configuration information, whether to allow an application to access the network. Specifically, the user equipment class control information classifies user equipment into user equipment that is allowed to access a network, and user equipment that is prohibited from accessing a network. The user equipment that is allowed to access the network may be referred to as a user equipment whitelist, and the user equipment that is prohibited from accessing the network may be referred to as a user equipment blacklist. The class of the user equipment may be a class in an existing access class barring (ACB) mechanism, or may be a class that is set by an operator, for example, an operator may classify user equipment into different classes according to credit statuses. Therefore, a user equipment class in the user equipment class control information may correspond to a class in the ACB mechanism, or may correspond to a user equipment class that is set by an operator.
Optionally, as another embodiment, the application configuration information includes classified identification information of the application that is allowed to access the network or classified identification information of the application that is prohibited from accessing the network, and the access control information may include classified control information, where the classified control information is used to control a category of an application that accesses the network. The classified control information is consistent with a classification manner of the identification information of the application that is allowed to access the network (or the identification information of the application that is prohibited from accessing the network). When the access network device and the core network device are configured, it is configured that the classified control information determined by the access network device is the same as a classification manner of identification information of an application by the core network device. For example, the classified control information may be priority information, congestion degree information, or group information of a user. Specifically, the classified identification information of the application that is allowed to access the network is classified according to a priority, or the classified identification information of the application that is prohibited from accessing the network is classified according to a priority, and correspondingly, the classified control information is priority information. In the example in Table 1, the classified control information may be the priority 1, or the priority 2, or the priority 3. The classified identification information of the application that is allowed to access the network is classified according to a congestion degree, or the classified identification information of the application that is prohibited from accessing the network is classified according to a congestion degree, and correspondingly, the classified control information is congestion degree information. In the example in Table 2, the classified control information may be the level 1, or the level 2, or the level 3. The classified identification information of the application that is allowed to access the network is classified according to an application group, or the classified identification information of the application that is prohibited from accessing the network is classified according to an application group, and correspondingly, the classified control information is group information of the application. In the example in Table 3, the classified control information may be the group 1, or the group 2, or the group 3. Further, the access control information may further include user equipment class control information, that is, the access control information includes user equipment class control information and classified control information.
In a case in which the access network device determines the access control information with reference to the access reference indicator, the access control information may correspond to the access reference indicator, and the access control information may also not correspond to the access reference indicator. For example, if the access reference indicator is classified reference information and the classified reference information is a reference priority, the access control information may be priority information, or may be other information such as group information of the application. Further, in a case in which the access reference indicator is a reference priority and the access control information is priority information, the priority information in the access control information may be equal to or may be unequal to the reference priority in the access reference indicator.
406. The access network device sends the access control information to user equipment. The access control information may be broadcast by using a system broadcast message, or in a case in which the user equipment is in connected mode, the access control information may be sent to the user equipment by using dedicated signaling. Specifically, in a case in which an access layer of the user equipment receives the access control information, the access layer of the user equipment sends the access control information to a protocol stack upper layer. If the access control information includes user equipment class control information, and the user equipment class control information is determined according to the ACB mechanism, the access layer also sends the user equipment class control information (that is, a user equipment class in the ACB mechanism) to the protocol stack upper layer. Further, receiving, by the user equipment, the access control information, or feeding back, by the access layer, the access control information to the protocol stack upper layer is controlled by the protocol stack upper layer. Specifically, triggered by an application, the protocol stack upper layer initiates, to the access layer, a request for acquiring the access control information. The access layer reads, according to the request of the protocol stack upper layer, the broadcast information that is sent by the access network device and that includes the access control information, and feeds back the read access control information to the protocol stack upper layer.
Optionally, when the access network device sends the access control information to the user equipment, the access network device may further send a congestion control indicator to the user equipment, to notify the user equipment that it may be determined, according to the access control information and the application configuration information, whether to allow an application to access the network. In addition, the user equipment may also determine, in a case in which the user equipment receives the access control information, that it may be determined, according to the access control information and the application configuration information, whether to allow an application to access the network.
407. The user equipment determines, according to the access control information and the application configuration information, whether to allow an application of the user equipment to access the network.
The access control information includes the user equipment class control information, and in this case, the determining, by the user equipment according to the access control information and the application configuration information, whether to allow an application of the user equipment to access the network includes: determining, by the user equipment according to a class of the user equipment, the class control information, and the application configuration information, whether to allow the application of the user equipment to access the network. For example, it is assumed that the class control information is a user equipment whitelist and the application configuration information is an application whitelist. The user equipment first needs to determine whether the class of the user equipment is in the user equipment whitelist. If the class of the user equipment is in the user equipment whitelist, the user equipment continues to perform determining on the application of the user equipment according to the application configuration information. If identification information of the application of the user equipment is in the application whitelist, the application is allowed to access the network; if the identification information of the application of the user equipment is not in the application whitelist, the application of the user equipment is prohibited from accessing the network. If the class of the user equipment is not in the user equipment whitelist, the user equipment directly prohibits the application of the user equipment from accessing the network. A determining method used when the class control information is a user equipment blacklist and/or the application configuration information is an application blacklist is similar, and does not need to be described in detail herein.
Optionally, as an embodiment, the determining, by the user equipment according to a class of the user equipment, the class control information, and the application configuration information, whether to allow the application of the user equipment to access the network includes: receiving, by a protocol stack upper layer of the user equipment, the user equipment class control information that is sent by an access layer of the user equipment, and determining, by the protocol stack upper layer according to the class of the user equipment, the user equipment class control information, and the application configuration information, whether to allow the application of the user equipment to access the network, where the class of the user equipment is stored at the protocol stack upper layer or the class of the user equipment is received from the access layer. If the class of the user equipment is a class in the ACB mechanism, the class of the user equipment is received from the access layer. If the class of the user equipment is a class that is set by an operator, the class of the user equipment may be stored at the protocol stack upper layer.
Optionally, as another embodiment, the determining, by the user equipment according to a class of the user equipment, the class control information, and the application configuration information, whether to allow the application of the user equipment to access the network includes: determining, by an access layer of the user equipment according to the class of the user equipment and the user equipment class control information, whether to allow the application of the user equipment to access the network; in a case in which a protocol stack upper layer of the user equipment receives determining information that is sent by the access layer and that is used to instruct to allow the application of the user equipment to access the network, determining, by the protocol stack upper layer according to the application configuration information, whether to allow the application of the user equipment to access the network; and in a case in which the protocol stack upper layer receives determining information that is sent by the access layer and that is used to instruct to prohibit the application of the user equipment from accessing the network, prohibiting, by the protocol stack upper layer, the application of the user equipment from being allowed to access the network. In other words, the access layer first determines, according to the class of the user equipment, whether to allow the application of the user equipment to access the network, and the protocol stack upper layer then further determines whether to allow the application of the user equipment to access the network.
The access control information includes the classified control information, and in this case, the determining, by the user equipment according to the access control information and the application configuration information, whether to allow an application of the user equipment to access the network includes: determining, according to the application configuration information and the classified control information, whether to allow the application of the user equipment to access the network. In this case, the application configuration information includes the classified identification information of the application that is allowed to access the network or the classified identification information of the application that is prohibited from accessing the network. For example, it is assumed that the application configuration information is an application whitelist. The user equipment first needs to determine whether the identification information of the application is in the application whitelist, and if the identification information of the application is in the application whitelist, the user equipment continues to determine, according to the classified control information, whether to allow the application to access the network. A determining method used when the application configuration information is an application blacklist is similar, and does not need to be described in detail herein.
Specifically, the determining, according to the application configuration information and the classified control information, whether to allow the application of the user equipment to access the network includes: receiving, by a protocol stack upper layer of the user equipment, the classified control information that is sent by an access layer, and determining, by the protocol stack upper layer according to the application configuration information and the classified control information, whether to allow the application of the user equipment to access the network. Using Table 1 as an example, the classified control information should be a priority. If the classified control information is the priority 3, all the applications whose identification information is A, B, and C respectively can access the network. If the classified control information is the priority 1, only the application whose identification information is A can access the network. Using Table 2 as an example, the classified control information should be congestion degree information. If the classified control information is the level 3, all the applications whose identification information is A, B, and C respectively can access the network. If the classified control information is the level 1, only the application whose identification information is A can access the network. Using Table 3 as an example, the classified control information should be group information of the application. If the classified control information is the group 3, all the applications whose identification information is A, B, and C respectively can access the network. If the classified control information is the group 1, only the application whose identification information is A can access the network. In addition, in the examples in Table 1 to Table 3, assuming that there are applications whose identification information is not A, B, or C (for example, an application whose identification information is D), none of these applications can access the network because the identification information of these applications is not in Table 1 to Table 3.
The access control information is the user equipment class control information and the classified control information, and in this case, the determining, by the user equipment according to the access control information and the application configuration information, whether to allow an application of the user equipment to access the network includes: determining, according to a class of the user equipment, the user equipment class control information, the application configuration information, and the classified control information, whether to allow the application of the user equipment to access the network. For example, it is assumed that the class control information is a user equipment whitelist and the application configuration information is an application whitelist. The user equipment first needs to determine, according to the class control information, whether the class of the user equipment is in the user equipment whitelist. If the class of the user equipment is in the user equipment whitelist, the user equipment continues to determine, according to the application configuration information, whether the identification information of the application of the user equipment is in the application whitelist. If the class of the user equipment is not in the user equipment whitelist, the user equipment directly prohibits the application of the user equipment from accessing the network. If the identification information of the application is in the application whitelist, the user equipment continues to determine, according to the classified control information, whether to allow the application to access the network. If the identification information of the application is not in the application whitelist, the user equipment directly prohibits the application from accessing the network. A determining method used when the class control information is a user equipment blacklist and/or the application configuration information is an application blacklist is similar, and does not need to be described in detail herein.
Optionally, as an embodiment, the determining, according to a class of the user equipment, the user equipment class control information, the application configuration information, and the classified control information, whether to allow the application of the user equipment to access the network includes: receiving, by a protocol stack upper layer of the user equipment, the user equipment class control information that is sent by an access layer of the user equipment, and determining, by the protocol stack upper layer according to the class of the user equipment, the user equipment class control information, the application configuration information, and the classified control information, whether to allow the application of the user equipment to access the network, where the class of the user equipment is stored at the protocol stack upper layer or the class of the user equipment is received from the access layer. If the class of the user equipment is a class in the ACB mechanism, the class of the user equipment is received from the access layer. If the class of the user equipment is a class that is set by an operator, the class of the user equipment may be stored at the protocol stack upper layer.
Optionally, as another embodiment, the determining, according to a class of the user equipment, the user equipment class control information, the application configuration information, and the classified control information, whether to allow the application of the user equipment to access the network includes: determining, by an access layer of the user equipment according to the class of the user equipment and the user equipment class control information, whether to allow the application of the user equipment to access the network; in a case in which a protocol stack upper layer of the user equipment receives determining information that is sent by the access layer and that is used to instruct to allow the application of the user equipment to access the network, determining, by the protocol stack upper layer according to the application configuration information and the classified control information, whether to allow the application of the user equipment to access the network; and in a case in which the protocol stack upper layer receives determining information that is sent by the access layer and that is used to instruct to prohibit the application of the user equipment from accessing the network, prohibiting, by the protocol stack upper layer, the application of the user equipment from being allowed to access the network. In other words, the access layer first determines, according to the class of the user equipment, whether to allow the application of the user equipment to access the network, and the protocol stack upper layer then further determines whether to allow the application of the user equipment to access the network.
If it is determined that the application of the user equipment is allowed to access the network, the protocol stack upper layer normally initiates the application. If the user equipment is in idle mode, the protocol stack upper layer first requests to the access layer for radio resource control (RRC) connection establishment, so that the terminal is switched to the connected mode, and then initiates a service.
According to the embodiment shown in
The control unit 501 is configured to acquire application configuration information, where the application configuration information includes identification information of an application that is allowed to access a network or identification information of an application that is prohibited from accessing a network. Specifically, the receiving unit 502 may be configured to receive the application configuration information that is sent by a core network device. The application configuration information may be sent to the user equipment by the core network device by using Open Mobile Alliance Device Management (OMA DM), or may be sent to the user equipment by the core network device by using non-access stratum (NAS) signaling. The control unit 501 is specifically configured to determine the application configuration information received by the receiving unit 502 as the application configuration information. Alternatively, the control unit 501 may acquire application configuration information preconfigured in the user equipment 500, and determine the preconfigured application configuration information as the application configuration information.
The receiving unit 502 is configured to receive access control information that is sent by an access network device. Specifically, the access control information received by the receiving unit 502 may be broadcast by the access network device. Alternatively, when the user equipment 500 is in connected mode, the receiving unit 502 receives the access control information from the access network device by using dedicated signaling.
The control unit 501 is further configured to determine, according to the application configuration information and the access control information, whether to allow an application of the user equipment 500 to access the network.
