Referring to fig. 2, fig. 2 is a flowchart of a method for providing network access according to an embodiment of the present application, where the method for providing network access includes steps 201 to 203. Wherein:

201. the access network equipment broadcasts first information, and the first information comprises access information corresponding to a plurality of user groups.

In the embodiment of the application, the first information is system information, and the access network device sends the system information carrying the access information to the terminal device in a broadcast manner. In addition, the access information may also be sent to the terminal device by the access network device through other manners, which is not limited in this embodiment of the present application.

In one possible implementation, the plurality of subscriber groups includes a subscriber group and a non-subscriber group. The AP cell generally adopts three modes, which are a closed mode, an open mode, and a hybrid mode. In the closed mode, only the signed user can access the network, and the non-signed user cannot access the network; in open mode, all users can access the network; in the mixed mode, all the users can access the network, but some users are subscribers, some users are non-subscribers, and in a general case, the subscriber grade is higher than that of the non-subscribers. In this possible implementation, the AP cell is a mixed mode cell.

In another possible implementation, the plurality of subscriber groups includes a plurality of subscriber groups and a plurality of non-subscriber groups. In this possible implementation, the AP cell is a network shared cell. The cell includes a plurality of Public Land Mobile Networks (PLMNs), and typically, only one PLMN is used for access by a terminal device of a non-subscriber group, and the remaining PLMNs are used for access by terminal devices of a plurality of subscriber groups. The grades of each subscriber group are different, and in general, the higher the grade, the more network resources are acquired by the terminal device users of the subscriber group.

The method for determining the user group of the terminal device by the terminal device may be two methods:

the first mode is as follows: the terminal equipment receives a cell access identifier broadcasted by the access network equipment; if the subscription information stored by the terminal equipment has the cell access identifier, the terminal equipment determines that the user group where the user of the terminal equipment is located is a subscription user group; and if not, the terminal equipment determines that the user group where the user of the terminal equipment is located is a non-signed user group. The subscription information stored by the terminal device includes access identifiers that the plurality of terminal devices can access the cell.

If the AP cell is a mixed-mode cell, there is usually only one access identifier broadcasted by the access network device, and the cell access identifier broadcasted by the access network device is any one of the following identifiers: closed Access Group (CAG) ID, Closed Subscriber Group (CSG) ID, or Stand-alone non-public networks (SNPN) ID.

If the AP cell is a network shared cell, the access identifier broadcasted by the AP cell is usually two or more. Under a network sharing cell, the access identifier of the cell broadcasted by the access network equipment has two modes, and the access identifier broadcasted by the access network equipment in the first mode comprises any one of PLMN ID and CSG ID, PLMN ID and CAG ID or PLMN ID and SNPN ID. Under the same cell, different subscriber groups correspond to CSG IDs, the CAG IDs or SNPN IDs are the same, but the corresponding PLMN IDs are different, and the terminal equipment determines a specific corresponding subscriber group according to the different PLMN IDs. Or the corresponding PLMN ID parts are the same, but the CSG ID, the CAG ID or the SNPN ID are different, and a corresponding specific subscriber group is determined according to the different IDs. The access identifier broadcasted by the access network device in the second mode includes any one of CSG ID, CAG ID or SNPN ID, and the terminal device determines a specific corresponding subscriber group through the access identifier. If the subscription information stored in the terminal equipment has two or more access identifications corresponding to the cell access identification broadcast by the access network equipment, the terminal equipment randomly determines a subscription user group corresponding to one access identification, and performs access control by adopting the access parameters corresponding to the subscription user group. If the access control is successful, the terminal equipment determines that the user group corresponding to the user of the terminal equipment is the signed user group, and the resource corresponding to the signed user group is adopted in the subsequent random access process or network resource acquisition; if the access control fails, the terminal equipment randomly determines the signed user groups corresponding to other access identifications, and performs access control through the access parameters corresponding to the signed user groups.

The second way is: and the terminal equipment receives indication information broadcast by the access network equipment, wherein the indication information is used for triggering prompt information to prompt a terminal equipment user to input a password or triggering the terminal equipment to search whether to store password information related to the AP. If the terminal equipment user inputs the password or the terminal equipment determines that the password information related to the AP is stored, the terminal equipment determines that the user group where the terminal equipment user is located is a signed user group; and if the terminal equipment user does not input the password and the terminal equipment determines that the password information related to the AP is not stored, the terminal equipment determines that the user group where the terminal equipment user is located is a non-signed user group.

The manner in which the terminal device determines the user group in which the user of the terminal device is located may also be other manners, which is not limited in this application embodiment.

In one possible implementation, the first information includes a plurality of Access Category (AC) values, and each AC value corresponds to Access information of a plurality of user groups. The AC value is generated according to the service type of the terminal triggering data transmission or the reason of initiating the request, and is used to instruct the terminal device to determine the value of the access parameter used in the access control process. Each AC value corresponds to at least one set of access information. The access information includes access control parameters. The access control parameters include one or more of: a unified access control barring parameter uac-BarringFactor, a unified access control barring time uac-BarringTime, or a unified barring identity uac-BarringForAccessIdentity. The access control parameters may include other parameters besides the above parameters, which is not limited in this embodiment of the present application.

uac-BarringFactor is used to compare with the generated random number of the terminal device. And if the preset requirements are met, completing access control. The preset requirement may be that the size of the random number generated by the terminal device is larger than uac-BarringFactor, or that the value of the random number generated by the terminal device is smaller than uac-BarringFactor, which is not limited in the embodiment of the present application. The success rate of the access control of the terminal equipment can be changed by changing the value of uac-BarringFactor. For example, the preset requirement is that the size of the random number generated by the terminal equipment is larger than uac-BarringFactor, and the random number which can be generated by the terminal equipment is within 0-100. If the value of uac-BarringFactor is 50, the success rate of access control of the terminal equipment is 50%; if the value of BarringFactor is 75, the success rate of access control of the terminal equipment is 25%. Therefore, when the AP cell is in the hybrid mode, under the same AC value, the BarringFactor corresponding to the subscribed user group makes the probability that the terminal device accesses the network greater than the probability that the BarringFactor corresponding to the non-subscribed user group makes the terminal device access the network. When the AP cell is in a network sharing cell mode, under the same AC value, the BarringFactor corresponding to the signed user group enables the probability that the terminal equipment is accessed into the network to be greater than the probability that the terminal equipment is accessed into the network by the BarringFactor corresponding to the non-signed user group, and the BarringFactor corresponding to the signed user group with a high grade enables the probability that the terminal equipment is accessed into the network to be greater than the probability that the terminal equipment is accessed into the network by the BarringFactor corresponding to the signed user group with a low grade.

uac-BarringTime is the time required for rollback after the access control of the terminal equipment fails, i.e. the connection request cannot be initiated within the uac-BarringTime time. If the AP cell is the hybrid mode and in the same AC value, uac-BarringTime corresponding to the subscribed user group is smaller than uac-BarringTime corresponding to the non-subscribed user group. If the cell is in the network sharing cell mode, in the same AC value, uac-BarringTimes corresponding to the subscribed user groups are all smaller than uac-BarringTimes corresponding to the non-subscribed user groups, and uac-BarringTimes corresponding to the subscribed user groups with high levels are smaller than those of the subscribed user groups with low levels.

uac-BarringForAccess identity contains the identifier for forbidding partial terminal equipment to access. If the access identifier of the terminal device is the identifier contained in uac-BarringForAccessIdentity, the terminal device will not be able to complete access control. If the AP cell is the hybrid mode and in the same AC value, the uac-barringForaccessIdentity number corresponding to the subscriber group is less than the uac-barringForaccessIdentity corresponding to the non-subscriber group. If the cell is in the network sharing cell mode, in the same AC value, uac-BarringForaccessityIdentity corresponding to the subscriber group is less than uac-BarringForaccessityIdentity corresponding to the non-subscriber group, and uac-BarringForaccessityIdentity corresponding to the subscriber group with a high grade is less than the subscriber group with a low grade.

In another implementation, the access information includes random access information. The random access information includes one or more of: random access resources, random access parameters or access mode indication information.

Wherein the random access resource comprises one or more of the following resources: a random access transmission opportunity (RO) resource, an uplink shared channel (PO) resource, a random access channel (PRACH) resource or an uplink sending resource. The random access resource specifically comprises: time domain and/or frequency domain resources sent by a Preamble, a Preamble list, time domain and/or frequency domain resources sent by a PUSCH, and uplink sending resources transmitted by a packet. Besides, the random access resource may also include other resources, which is not limited in this embodiment of the present application. And if the AP cell mode is a mixed mode cell, additionally configuring random access resources corresponding to the signed user group, wherein the resources are different from the random access resources corresponding to the non-signed user group. If the AP cell is a network shared cell, different subscriber groups are configured to respectively correspond to different random access resources, and one implementation manner may be that a random access resource corresponding to a subscriber group with a high rank is more than a random access resource corresponding to a subscriber group with a low rank. Through different access resources used by the terminal equipment, the access network equipment can judge which user group the terminal equipment belongs to, and can preferentially process a user access request for a subscriber group with a high level. Besides, the random access resource may also include other resources, which is not limited in this application.

Wherein the random access parameters include one or more of: a power ramp parameter, a backoff parameter, or a maximum number of transmissions.

The power ramp parameter is used for increasing the power of the transmitted message based on the value of the power ramp parameter when the terminal equipment initiates random access again after the random access fails, so as to improve the probability of successful transmission of information. The larger the power rising parameter is, the larger the transmission power added value is, and the larger the probability of successful information transmission is; the smaller the power ramp parameter, the smaller the transmission power increase value, and the smaller the probability of successful transmission of information. If the AP cell mode is a mixed mode cell, the power rising parameter corresponding to the signed user group is larger than the power rising parameter corresponding to the non-signed user group. If the AP cell is a network sharing cell, the power climbing parameters corresponding to the signed user groups are all larger than the power climbing parameters corresponding to the non-signed user groups, and the power climbing parameters corresponding to the signed user groups with high levels are larger than the power climbing parameters corresponding to the signed user groups with low levels.

The back-off parameter is used for waiting for determining the back-off time based on the back-off parameter when the random access of the terminal equipment is initiated again after the random access fails. The larger the back-off parameter is, the longer the back-off time is, and the smaller the back-off parameter is, the shorter the back-off time is. If the AP cell mode is a mixed mode cell, the backspacing parameter corresponding to the signed user group is smaller than the backspacing parameter corresponding to the non-signed user group. And if the AP cell is a network sharing cell, the backspacing parameters corresponding to the signed user groups are all smaller than the backspacing parameters corresponding to the non-signed user groups, and the backspacing parameters corresponding to the signed user groups with high grades are smaller than the backspacing parameters corresponding to the signed user groups with low grades.

The maximum sending times are used for stopping a relevant random access process after the terminal equipment randomly fails for multiple times, and mainly comprise four-step random access processes; or a two-step random access process is used, and the process can return to a four-step random access process after multiple failures. The larger the value, the more random access procedures the terminal device can attempt, the greater the access probability. If the AP cell mode is a mixed mode cell, the maximum sending times corresponding to the signed user group is larger than the maximum sending times corresponding to the non-signed user group. If the AP cell is a network shared cell, the maximum transmission times corresponding to the subscriber groups may be greater than the maximum transmission times corresponding to the non-subscriber groups, and the maximum transmission times corresponding to the subscriber groups with a high level are greater than the maximum transmission times corresponding to the subscriber groups with a low level.

Besides, the access parameter may also include other parameters, which is not limited in this embodiment of the present application.

The access mode indication information is used for indicating the terminal equipment to determine to access the network by adopting a first access mode based on preset requirements, wherein the first access mode is any one of the following modes: four-step random access, two-step random access or packet transmission.

The four steps of random access are shown in fig. 3: the terminal equipment sends Msg1 to the access network equipment by adopting random access resources, wherein the Msg1 comprises a preamble; the terminal equipment receives the Msg2 sent by the access network equipment, and the second information comprises response information corresponding to the lead code; the terminal device sends Msg3 to the access network device, and the Msg3 comprises RRC messages; and the end device receives the Msg4 sent by the access network device, and the Msg4 comprises response information to the Msg 3. In the 5G NR, the air interface of the terminal device has three states, which are idle state, inactive state, and connected state. The idle-state terminal equipment is not connected with the base station, and only needs to initiate location updating, cell selection and reselection flow, receive paging and the like periodically; the terminal equipment in the inactive state does not need to inform the base station when moving in the range of the cell; the connected terminal device is connected with the network, and the network can schedule uplink and downlink data for the terminal device. If the terminal device in the non-connected state needs to perform data transmission with the access network device, the terminal device needs to perform state transition through random access and transition to the connected state. In the four-step random access, if the terminal device is in a connected state, the terminal can carry uplink data when sending Msg 3; and when the terminal equipment is in a non-connected state, the terminal equipment cannot carry uplink data, and the data can be sent only after random access is completed.

The steps of two-step random access are shown in fig. 4: the method comprises the steps that a terminal device sends MsgA to an access network device, wherein the MsgA comprises a preamble and an RRC message, and if the terminal device is in a connected state, the MsgA can comprise data; and the access network equipment sends the MsgB to the terminal equipment, wherein the MsgB contains response information to the MsgA. If the network equipment only receives the preamble sent by the terminal equipment in the two-step random access process, the network equipment only replies the response information of the preamble, and the terminal equipment changes the random access mode into four-step random access. If the terminal device is in idle state or inactive state, the MsgA sent by the terminal device in the two-step random access process can only contain RRC messages and cannot contain data, so that the terminal device needs to send data after the random access process is completed. The MsgA in the two-step random access contains the contents of Msg1 and Msg3 of the four-step random access, so that the two-step random access can reduce the time delay and signaling overhead compared with the four-step random access.

The steps of packet transmission are shown in fig. 5: the terminal equipment sends first information by adopting pre-configured dedicated resources (PUR) or pre-configured uplink resources of access network equipment, wherein the first information comprises preamble, RRC message and data, and the first information can not comprise preamble if the TA timer is not overtime or the TA state is effective; and the access network equipment sends second information, wherein the second information comprises response information of the data. The packet transmission can enable the terminal equipment to directly send data in a non-connected state, and the efficiency of the terminal equipment accessing to the network is effectively improved.

202. The terminal equipment acquires first access information corresponding to the user group where the user of the terminal equipment is located from the access information corresponding to the plurality of user groups.

In a possible implementation manner, the step 202 specifically includes: the terminal equipment generates a first AC value; and the terminal equipment acquires access control parameters corresponding to the user group where the user of the terminal equipment is located from the access information corresponding to the first AC value in the first information. A specific example is adopted below to describe a manner in which the terminal device obtains the access control parameters corresponding to the user group in which the user of the terminal device is located.

When the AP cell in which the terminal device is located is a mixed-mode cell, the preset requirement is that the size of the random number generated by the terminal device is greater than uac-BarringFactor. If the generated AC value is 1, the terminal device may determine, based on table 1, two parameters uac-BarringTime and uac-BarringFactor corresponding to the AC value of 1. If the user group in which the user of the terminal device is located is a subscribed user group, the terminal device may determine that the first access parameter uac-BarringTime is a1 and the first access parameter uac-BarringFactor is C1; if the user group in which the user of the terminal device is located is a non-subscribed user group, the terminal device may determine that the first access parameter uac-BarringTime is B1 and uac-BarringFactor is D1. Wherein A1 is less than B1 and C1 is less than D1. It can be seen that uac-BarringTime corresponding to the subscriber group is less than uac-BarringTime of the non-subscriber group, and uac-BarringFactor corresponding to the subscriber group is less than uac-BarringFactor corresponding to the non-subscriber group. Therefore, the success rate of accessing the network by the terminal equipment of which the user belongs to the group of the signed users is greater than that by the terminal equipment of which the user belongs to the group of the non-signed users. The method is favorable for improving the success rate of the subscriber accessing the network. In one implementation the available values of uac-BarringFactor are: p00, p05, p10, p15, p20, p25, p30, p40, p50, p60, p70, p75, p80, p85, p90, p 95; the available values for uac-BarringTime are: s4, s8, s16, s32, s64, s128, s256, s 512.

TABLE 1

When the AP cell where the terminal device is located is a network sharing cell, the preset requirement is that the size of the random number generated by the terminal device is larger than uac-BarringFactor, and the level of the signed user group 1 is higher than that of the signed user group 2. If the generated AC value is 1, the terminal device may determine, based on table 2, two parameters uac-BarringTime and uac-BarringFactor corresponding to the AC value of 1. If the user group in which the user of the terminal device is located is a subscriber group 1, the terminal device may determine that the first access parameter uac-BarringTime is a1 and uac-BarringFactor is D1; if the user group in which the user of the terminal device is located is a subscriber group 2, the terminal device may determine that the first access parameter uac-BarringTime is B1 and the first access parameter uac-BarringFactor is E1; if the user group in which the user of the terminal device is located is a non-subscribed user group, the terminal device may determine that the first access parameter uac-BarringTime is C1 and uac-BarringFactor is F1. Wherein A1 is less than B1 and less than C1, D1 is less than E1 and less than F1. It can be seen that uac-BarringTime corresponding to the contracted user group with the high level is smaller than uac-BarringTime corresponding to the contracted user group with the low level, and is smaller than uac-BarringTime corresponding to the non-contracted user group, and uac-BarringFactor corresponding to the contracted user group is smaller than uac-BarringFactor corresponding to the contracted user group with the low level, and is smaller than uac-BarringFactor corresponding to the non-contracted user group, so that the success rate of accessing the network by the terminal device of which the group in which the user is the contracted user group 1 is greater than the terminal device of which the group in which the user is the contracted user group 2, and is also greater than the terminal device of which the group in which the user is the non-contracted user group. The method is favorable for improving the success rate of the high-grade subscriber to access the network. In one implementation the available values of uac-BarringFactor are: p00, p05, p10, p15, p20, p25, p30, p40, p50, p60, p70, p75, p80, p85, p90, p 95; the available values for uac-BarringTime are: s4, s8, s16, s32, s64, s128, s256, s 512.

TABLE 2

In another possible implementation manner, the step 202 specifically includes: and the terminal equipment acquires the random access resource corresponding to the user group where the user of the terminal equipment is located from the random access information included in the access information corresponding to the plurality of user groups. A specific example is adopted below to describe a manner in which the terminal device obtains the random access resource corresponding to the user group in which the user of the terminal device is located.

When the AP cell where the terminal equipment is located is a mixed-mode cell, the resource of the random access resource A is more than that of the random access resource B, and the grade of the signed user group 1 is higher than that of the signed user group 2. If the user group in which the user of the terminal device is located is a subscriber group, determining that the random access resource corresponding to the terminal device is a random access resource A based on the table 3; if the user group corresponding to the user of the terminal device is a non-subscribed user group, it may be determined that the random access resource corresponding to the terminal device is a random access resource B based on table 3. Because the resource of the random access resource A is more than that of the random access resource B, the random access resource of the terminal equipment grouped as the signed user group where the user is located is more than that of the terminal equipment grouped as the non-signed user group where the user is located, and therefore, the success rate of accessing the network by the terminal equipment grouped as the signed user group where the user is located is greater than that of the terminal equipment grouped as the non-signed user group where the user is located. By the method, the success rate of the subscriber accessing the network is improved.

		Subscriber grouping	Random access resource a
Non-subscriber grouping	Random access resource B

When the AP cell where the terminal equipment is located is a network sharing cell, the random access resource A is more than the random access resource B and more than the random access resource C, and the level of the signed user group 1 is higher than that of the signed user group 2. If the user group in which the user of the terminal device is located is a subscriber group 1, determining that the random access resource corresponding to the terminal device is a random access resource a based on table 4; if the user group in which the user of the terminal device is located is a subscriber group 2, determining that the random access resource corresponding to the terminal device is a random access resource B based on table 3; if the user group in which the user of the terminal device is located is a non-subscribed user group, it may be determined that the random access resource corresponding to the terminal device is the random access resource C based on table 3. Because the resource of the random access resource A is more than that of the random access resource B and more than that of the random access resource C, the resource of the terminal equipment of which the user belongs to the group of the signed user group 1 is more than the resource of the terminal equipment of which the user belongs to the group of the signed user group 2 than the resource of the terminal equipment of which the user belongs to the group of the non-signed user group, so that the success rate of accessing the network by the terminal equipment of which the user belongs to the group of the signed user group 1 is greater than that of the terminal equipment of which the user belongs to the group of the signed user group 2 and is also greater than that of the terminal equipment of which the user belongs to the group of the non-signed user group. By the method, the success rate of the high-grade subscriber accessing the network is improved.

TABLE 4

User grouping	Random access resource
		Subscriber group 1	Random access resource a

		Non-subscriber grouping	Random access resource C

In another possible implementation manner, the step 202 specifically includes: and the terminal equipment acquires the random access parameters corresponding to the user group where the user of the terminal equipment is located from the random access information included in the access information corresponding to the plurality of user groups. A specific example is adopted below to describe a manner in which the terminal device obtains the random access parameter corresponding to the user group in which the user of the terminal device is located.

When the AP cell in which the terminal device is located is a mixed-mode cell, if the user group in which the user of the terminal device is located is a contracted user group, it may be determined that the power ramp parameter determined by the terminal device is a and the backoff parameter is C based on table 5; if the subscriber group in which the subscriber of the terminal device is located is a non-subscriber group, it may be determined based on table 5 that the power ramp parameter determined by the terminal device is B and the backoff parameter is D. In table 5, the value of a is greater than the value of B, and the value of C is less than the value of D, it can be seen that the power ramp parameter of the subscribed user group is higher than the power ramp parameter corresponding to the non-subscribed user group, and the back-off parameter corresponding to the subscribed user group is lower than the back-off parameter corresponding to the non-subscribed user group. Therefore, the success rate of accessing the network again by the terminal equipment of which the group in which the user is located is the signed user group is greater than that of the terminal equipment of which the group in which the user is located is the non-signed user group. By the mode, the success rate of the subscriber accessing the network is improved.

TABLE 5

User grouping	Power ramp parameter	Backoff parameter
			Subscriber grouping	A	C
Non-subscriber grouping	B	D

When the AP cell where the terminal device is located is a network sharing cell, the level of the signed user group 1 is higher than that of the signed user group 2. If the user group in which the user of the terminal device is located is a subscribed user group 1, determining that the power ramp parameter corresponding to the terminal device is a and the backoff parameter is D based on table 4; if the user group in which the user of the terminal device is located is a subscribed user group 2, determining that the power ramp parameter corresponding to the terminal device is B and the backoff parameter is E based on table 3; if the user group in which the user of the terminal device is located is a non-subscribed user group, it may be determined that the power ramp parameter corresponding to the terminal device is C and the backoff parameter is F based on table 3. In table 6, the value of a is greater than the value of B and greater than the value of C, the value of E is less than the value of F and less than the value of G, it can be seen that the power ramp parameter corresponding to the group 1 of the subscribed users is higher than the power ramp parameter corresponding to the group 2 of the subscribed users than the group of the non-subscribed users, and the backoff parameter corresponding to the group 1 of the subscribed users is lower than the backoff parameter corresponding to the group 2 of the subscribed users than the backoff parameter corresponding to the group 2 of the non-subscribed users, so that the success rate of the access to the network by the terminal device whose group is the group 1 of the subscribed users is greater than the terminal device whose group is the group 2 of the subscribed users and is also greater than the terminal device whose group is the group of the non-subscribed users. By the mode, the success rate of the high-grade subscriber accessing the network is improved.

TABLE 6

User grouping	Power ramp parameter	Backoff parameter
			Subscriber group 1	A	D
Subscriber group 2	B	E
			Non-subscriber grouping	C	F

In another possible implementation manner, the step 202 specifically includes: the terminal equipment acquires access mode indication information corresponding to the user group where the user of the terminal equipment is located from random access information included in the access information corresponding to the user groups; and the terminal equipment determines that the terminal equipment is to access the network by adopting the first access mode based on the indication information. The specific steps of the terminal device determining that the terminal device will access the network in the first access mode based on the indication information are as follows: if the user group of the terminal equipment is a signed user group, the terminal equipment accesses the network by adopting a two-step random access or packet transmission mode; if the group of the user of the terminal equipment is a non-signed user group, the terminal equipment needs to determine whether the preset requirement is met, if not, the network is accessed by adopting a four-step random access mode, and if so, the network is accessed by adopting a two-step random access or packet transmission mode. Because the speed of accessing the network can be effectively improved by adopting a two-step random access or packet transmission mode, the realization mode is favorable for improving the speed of accessing the network by the subscriber.

The preset requirement includes whether the cell signal value measured by the terminal device is greater than a preset threshold and/or whether the data to be sent by the terminal device is a preset data service type, for example, whether the configuration requirement is met by judging whether a logical channel identifier LCH ID or a data radio bearer identifier DRB ID of the data to be transmitted or whether the data is positioning data, and then a packet transmission mode can be used. The preset requirement may also be whether the amount of data to be transmitted is less than a certain threshold, and if so, a packet transmission mode may be used. By the method, the terminal equipment is prevented from failing to try two-step random access or packet transmission for many times due to poor signals, resources of other users are occupied, and meanwhile, data services with higher requirements on time delay can reduce the time delay of data transmission of the services by adopting a two-step random access or packet transmission mode, so that the corresponding requirements of the data services are met. The preset requirement may also have other requirements besides the above-described requirement, for example, the data sent by the terminal device is required not to exceed a preset threshold, and the like, which is not limited in the embodiment of the present application.

In another possible implementation manner, the specific step of determining, by the terminal device, that the terminal device will access the network in the first access manner based on the acquired indication information is as follows: if the group where the user of the terminal device is located is a contracted user group, wherein the indication information of the contracted user group indicates that the terminal device can ignore one or more preset requirements, including ignoring a threshold requirement for using a corresponding access mode and/or a DRB configuration requirement and/or a data volume threshold requirement, and directly using a two-step random access or packet transmission mode.

203. The terminal equipment accesses the network based on the first access information.

By the method described in the embodiment of the application, the terminal device receives first information sent by the access network device, wherein the first information comprises access information corresponding to a plurality of user groups; the terminal equipment acquires first access information corresponding to a user group where a user of the terminal equipment is located from the access information corresponding to the plurality of user groups; the terminal equipment accesses the network based on the first access information, and the success probability of the signed user accessing the network is favorably improved.

Referring to fig. 6, fig. 6 is a flowchart of a method for network access provided by an embodiment of the present application, where the method for network access includes steps 601 to 605. Wherein:

601. the access network equipment broadcasts first information, and the first information comprises access information corresponding to a plurality of user groups.

602. The terminal equipment acquires first access information corresponding to the user group where the user of the terminal equipment is located from the access information corresponding to the plurality of user groups.

603. The terminal equipment accesses the network based on the first access information.

The specific implementation manners of steps 201 to 203 are the same as those of steps 601 to 603, and are not described herein again.

604. If the access network equipment determines that the user group where the user of the terminal equipment is located is a non-signed user group and the terminal equipment accesses the network based on the access information corresponding to the signed user group, the access network equipment sends punishment information to the terminal equipment.

In the embodiment of the application, after the terminal device and the access network device are successfully connected and data interaction is carried out, the access network device can determine the user group corresponding to the user of the terminal device through the information sent by the terminal device, and if the terminal device is a non-subscriber, the access network device is accessed based on the access information corresponding to the subscriber group, so that the non-subscriber occupies the resources of the subscriber, and the probability of successful network access of the subscriber is reduced. Therefore, the access network device will send penalty information to the terminal device, so that the terminal device starts a penalty mechanism.

In an implementation manner, if the AP cell is a network shared cell, if the access network device determines that the terminal device of the lower-level subscriber group performs random access by using the access information corresponding to the higher-level subscriber group, the access network device sends penalty information to the terminal device. By the mode, the resources of the high-level subscribers are prevented from being used by the low-level subscribers.

605. The terminal device starts a penalty mechanism.

In the embodiment of the present application, the penalty mechanism includes one or more of the following mechanisms: and releasing the radio resource control RRC, wherein the terminal equipment cannot initiate a connection request within preset time or the grade of a user group where the user of the terminal equipment is located is reduced. In addition to the above-mentioned penalty mechanisms, other penalty mechanisms may be used, which is not limited in the embodiments of the present application. In this way, resources of the subscribers are prevented from being used by non-subscribers.
