The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

The access control method provided by the embodiment of the present invention may include:

Obtaining an SPI (Scheduled Priority Indicator) of the user requesting access, determining, according to the acquired SPI, whether the access condition of the user requesting the access is permitted, and if the determined access condition is met, granting the request Incoming user access.

Further, when determining whether to grant access conditions of the user requesting access according to the acquired SPI, different access conditions may be selected according to requirements.

Referring to FIG. 1, an access control method according to an embodiment of the present invention includes:

101: Obtain the SPI _n of the user requesting access;

When obtaining the SPI _n of the user requesting access, the ARP (Allocation/Retention Priority) of the user accessing the request may be pre-configured according to the service type of the user that is requested to access and the core network. The value is directly mapped to obtain the SPI _n6W of the user to which the request is accessed; or in the pre-configured scheduling priority indication table Looking for the SPI _n corresponding to the user requesting access, the scheduling priority indication table may be mapped according to the service type of each user and the ARP value pre-configured by the core network to the user to obtain the SPI _{n6W corresponding to the} user, The obtained SPI _n „ correspondence with the user is stored in the scheduling priority indication table.

102: Determine, according to the acquired SPI _n , an access condition of a user requesting access;

In the embodiment of the present invention, when determining the access condition of the user to be accessed, the bit rate is used as the measurement parameter of the service quality. The service quality may also refer to other parameters according to actual needs, and details are not described herein. In this embodiment, the access condition of the user requesting access according to the obtained SPI _n may include:

The _sum of the PBRs of the connected users whose SPI is smaller than SPI _{n is} greater than the _sum of the GBR (Guaranteed Bit Rate) of these users (the SPI is less than the SPI _n6W access users) and the first preset threshold. The product of Thd _L is determined as an access condition and can be:

Z PBR _t > Thd _L · Z GBR, ( 1 )

SPI<SPI _mw SPI<SPI _mw

Alternatively, the product of the sum of the _PBRs of the connected users _whose SPI is greater than or equal to SPI _n6W is greater than the sum of the _GBRs of the users (users with SPI greater than or equal to SPI _n ) and the second preset threshold Thd _eE is determined as access. Conditions can be:

Z PBR _t > Thd _GE - Z GBR, ( 2 )

SPI > SPI SPI ≥ SPI

"(Or the user, is equal to the SPI SPI SPI is equal to _{_n-n-SPI)} has access to the user's current PBR obtained is greater than the sum of those users," the sum of the product of GBR third preset threshold Thd _E is determined as access condition Can be:

Z PBR^ > Thd _E - Z GBR, ( 3 )

SPl=SPl _m SPI=SPI

103: Determine whether the determined access condition is satisfied, if yes, execute 104; otherwise, execute 105.

104: Allow the user accessing the request to access.

105: Reject the user access that the request is accessed.

When any one of the three access conditions in the above 102 is established, that is, the access condition is satisfied, the user accessing the request is permitted to access. If none of the three access conditions in the above 102 is established, the indication is not satisfied. If the access condition is reached, the user accessing the request is denied;

This embodiment is directed to the scheduling priority of the current new access user and the scheduling of the accessed user in the prior art. The priority relationship is obtained by obtaining the SPI of the user requesting access, determining the access condition of the user requesting access according to the SPI of the user requesting access, and granting the request access when the determined access condition is met. User access can maximize the access request of new users while ensuring user QoS, thereby improving the performance of the entire network, such as the user's QoS experience and system stability.

2, an access control method according to an embodiment of the present invention, in which a user with a high SPI is allowed to have absolute priority, that is, if the SPI of the user requesting access is higher than the SPI of the already accessed user, Users who request access can preempt the resources that are available to users with low SPI among the users that have been accessed, and force users with low SPI to go offline. The method can include:

201: Obtain SPI _new of the user requesting access;

Among them, the way to obtain SPI _n „ is basically the same as 101, and will not be described in detail here.

202: Determine, according to the acquired SPI _n , the access condition of the request access user;

In the embodiment of the present invention, the bit rate is used as the measurement parameter of the QoS, and the GBR of the user who has the SPI less than the SPU currently obtained by the user is greater than the GBR of the user that is requested to access, and the access condition may be:

∑ PBR, > GBR _new ( 4)

SP1<SP1

203: Determine whether the determined access condition is met, if yes, execute 204; otherwise, execute 205.

204: Allow the user accessing the request to access.

205: Reject the request for access for access.

In this embodiment, when the user is allowed to have a high priority, the user can determine whether the access condition is established by determining whether the access condition is established, and whether the user with the high scheduling priority preempts the resource occupied by the user with low scheduling priority, for example, In order to protect the needs of special users, such as: Gold users, the priority-prioritized switch is set to the open state. When the gold card user requests access, it can preempt the resources that other ordinary users are using. The service quality of the gold-protected users is protected; or the operator considers the requirement that the online users do not allow forced disconnection, and the switch that allows the priority of the priority is set to the closed state, no matter what user requests access, it cannot be preempted. Resources used by online users.

In addition, the access condition of the request access user determined according to the acquired SPI _{n in} 202 may also be combined with any one or more of the determined access conditions in 102, as long as any access condition is available. If the content is satisfied, the user accessing the request is permitted to access, and if any of the conditions cannot be satisfied, the user accessing the request is denied.

The embodiment of the present invention maximizes the quality of service of the SPI high user by allowing the user with high SPI to give priority to the user, and fully considers the needs of the special user, thereby improving the performance of the entire network, such as the user's QoS experience and system stability.
