S202: terminal carries out access control according to the default access restriction parameter that access network equipment is allocated to the terminal, or Person is allocated to the first default access style of the terminal according to access network equipment, and it is corresponding to be matched to the described first default access style Access restriction parameter, and carry out access control according to the access restriction parameter being matched to, or according to preset in the terminal Second default access style is matched to the corresponding access restriction parameter of the second default access style, and according to the access being matched to Limitation parameter carries out access control.
Terminal, which determines, to be needed to before access network equipment transmission connection request, and access network equipment determines default access restriction ginseng Several or the first default access style, and determining default access restriction parameter or the first default access style are sent to terminal.
Correspondingly, terminal receives the default access restriction parameter or default access style that access network equipment is sent.
Optionally, access network equipment according to public land mobile network (Public Land Mobile Network, PLMN) one of the type of the connection request to be initiated of type, terminal and slice type or a variety of determinations default accesses Limit parameter and/or the first default access style, wherein the type of the connection request be access layer (Access Stratum, AS) scheduling request or Non-Access Stratum scheduling request or service request are enabled the terminal to according to specific PLMN or specific Connection request type or slice type carry out access control.Specifically, access network equipment can in the following manner in appoint It anticipates a kind of according to the determining default access restriction parameter and/or the first default access style:
PLMN type or slice type that mode one, access network equipment are supported according to access cell off the net or Person's connection request type (AS scheduling request or NAS signaling request or service request), determine default access restriction parameter and/or The first default access style.For example, different default access restriction ginsengs is arranged according to different PLMN types in access network equipment Different default connect is arranged according to different slice types in the several and/or first default access style or access network equipment Enter to limit parameter and/or the first default access style or access network equipment according to different connection request types, setting is not Same default access restriction parameter and/or the first default access style.Alternatively, access network equipment may be terminal setting system One limitation parameter and/or the first default access style.For example, access network equipment can be for different PLMN setting unifications System can be arranged for different connection request types by limiting parameter and/or the first default access style or access network equipment One limitation parameter and/or the first default access style.
Mode two, access network equipment are according at least two in the type of PLMN type, slice type and connection request, really Fixed default access restriction parameter and/or the first default access style.For example, access network equipment is directed to different PLMN types, Further according to the type of connection request or slice type, different default access restriction parameter is set and/or this is first default Access style, alternatively, being directed to different slice types, further according to the type of connection request or PLMN type, setting is different Default access restriction parameter and/or the first default access style, alternatively, be directed to different connection requests type, into one Different default access restriction parameter and/or the first default access style are arranged according to slice type or PLMN type for step.Again Such as, access network equipment is for the different slice types under different PLMN types, further according to the type of connection request, setting Different default access restriction parameters and/or the first default access style, alternatively, access network equipment is directed to different PLMN types The type of lower different connection request is arranged different default access restriction parameters and/or is somebody's turn to do further according to slice type First default access style, alternatively, type of the access network equipment for connection request different under different PLMN types, further According to slice type, different default access restriction parameter and/or the first default access style etc. are set.
After access network equipment determines default limitation parameter and/or the first default access style, it can be incited somebody to action by system message Identified default limitation parameter and/or the first default access style are broadcast to terminal.If terminal is in connected state, access net is set It is standby identified default limitation parameter and/or the first default access style to be allocated to by terminal by dedicated signaling.
Optionally, the second default access style is as defined in agreement, such as terminal is provided according to agreement when leaving the factory, by Two default access styles are pre-configured in terminal.
It is terminal configuration in access network equipment after terminal obtains the first default access style or the second default access style The second mapping relations in be matched to the first default access style or the corresponding access restriction parameter of the second default access style, and Access control is carried out according to the access restriction parameter being matched to.For example, if terminal coupling to access restriction parameter be 80% (to connect Entering probability is that 80%), 200 (a length of 200s when forbidding accessing), the range for the random number that terminal generates is 1-10, when terminal generates Random number be less than or equal to 8, it is determined that the terminal meets the access restriction parameter, and sends connection to access network equipment and ask It asks, otherwise, it determines the terminal is unsatisfactory for the access restriction parameter, forbids the terminal to send in 200s to access network equipment and connect Request.Due to terminal according to default access restriction parameter carry out access control with according to being matched to the first default access style or the The principle that the corresponding access restriction parameter of two default access styles carries out access control is similar, and details are not described herein again.
In this way, terminal need to access network equipment send connection request when, if matching less than the connection request Corresponding access style, or it is matched to the corresponding access style of the connection request, but match corresponding less than the access style Access restriction parameter then carries out access control according to default access restriction parameter, or connects according to default access style is corresponding Enter to limit parameter and carry out access control, solves terminal and matching access style corresponding less than connection request, or the company of being matched to Access control can not be carried out when connecing the corresponding access style of request, but matching access restriction parameter corresponding less than the access style The problem of, avoid wireless communication system from overloading.
