The wireless communication technology of Long Term Evolution (LTE) or new radio (NR) is used between the terminal devices and AP.

AP can be flexibly deployed in homes, enterprises and other places to provide services for a small number of users.

[0003] As the number of users continues to increase, the AP cell load continues to increase, and network resources are gradually limited.

Among them, the access network device can provide communication services to multiple terminal devices.

[0062] The access network device in the embodiment of the present application may be a small cell base station, an access point (AP) or a home base station or a non-public network cell base station. A base station is a device deployed in a radio access network (RAN) to provide wireless communication functions.

The embodiment of the present application defines the unidirectional communication link from the access network to the terminal as a downlink, the data transmitted on the downlink is downlink data, and the transmission direction of the downlink data is called the downlink direction; and the unidirectional communication link from the terminal to the access network is an uplink, the data transmitted on the uplink is uplink data, and the transmission direction of the uplink data is called the uplink direction.

[0066] Based on the network architecture and devices described above, a network access method provided by an embodiment of the present application is introduced below. Figure 2 , Figure 2 2 is a flow chart of a network access method provided by an embodiment of the present application, and the network access method includes steps 201 to 203. Among them:

[0067] 201. An access network device broadcasts first information, where the first information includes access information corresponding to multiple user groups.

[0068] In the embodiment of the present application, the first information is system information, and the access network device carries the access information in the system information and sends it to the terminal device in a broadcast manner. In addition, the access information can also be sent from the access network device to the terminal device in other ways, which is not limited in the embodiment of the present application.

[0069] In a possible implementation, the multiple user groups include a contracted user group and a non-contracted user group. AP cells usually adopt three modes, namely, closed mode, open mode and mixed mode. In the closed mode, only contracted users can access the network, and non-contracted users cannot access; in the open mode, all users can access the network; in the mixed mode, all users can access the network, but some users are contracted users and some users are non-contracted users. Under normal circumstances, the level of contracted users is higher than that of non-contracted users. In this possible implementation, the AP cell is a mixed mode cell.

[0070] In another possible implementation, the multiple user groups include multiple contracted user groups and non-contracted user groups. In this possible implementation, the AP cell is a network sharing cell. The cell includes multiple public land mobile networks (PLMNs). Usually, only one PLMN is used for terminal device access of non-contracted user groups, and the remaining PLMNs are used for terminal device access of multiple contracted user groups. Each contracted user group has a different level. Under normal circumstances, the terminal device users of the higher-level contracted user group obtain more network resources.

[0071] There are two ways for a terminal device to determine the user group to which the user of the terminal device belongs:

[0072] The first method is: the terminal device receives the cell access identifier broadcast by the access network device; if the cell access identifier is included in the contract information stored in the terminal device, the terminal device determines that the user group to which the user of the terminal device belongs is a contract user group; if not, the terminal device determines that the user group to which the user of the terminal device belongs is a non-contract user group. The contract information stored in the terminal device includes multiple access identifiers of cells that the terminal device can access.

[0073] If the AP cell is a hybrid mode cell, the access network device usually broadcasts only one access identifier, and the cell access identifier broadcast 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.

[0074] If the AP cell is a network shared cell, the access identifiers broadcast by the AP cell usually have two or more. In a network shared cell, there are two ways to broadcast the access identifier of the cell by the access network device. In the first way, the access identifier broadcast by the access network device includes any one of the PLMN ID and CSG ID, PLMN ID and CAG ID, or PLMN ID and SNPN ID. In the same cell, different subscribed user groups correspond to the same CSG ID, CAG ID or SNPN ID, but the corresponding PLMN ID is different. The terminal device determines the corresponding specific subscribed user group according to the different PLMN IDs. Or the corresponding PLMN ID part is the same, but the CSG ID, CAG ID or SNPN ID is different, and the corresponding specific subscribed user group is determined according to the different IDs. In the second way, the access identifier broadcast by the access network device includes any one of the CSG ID, CAG ID or SNPN ID, and the terminal device determines the corresponding specific subscribed user group through the access identifier. Among them, if the contract information stored in the terminal device has two or more access identifiers corresponding to the cell access identifier broadcast by the access network device, the terminal device will randomly determine a contract user group corresponding to an access identifier, and perform access control by using the access parameters corresponding to the contract user group. If the access control is successful, the terminal device will determine the user group corresponding to the user of the terminal device as the contract user group, and will use the resources corresponding to the contract user group in the subsequent random access process or network resource acquisition; if the access control fails, the terminal device will randomly determine the contract user group corresponding to other access identifiers, and perform access control by using the access parameters corresponding to the contract user group.

[0075] The second method is: the terminal device receives the indication information broadcasted by the access network device, and the indication information is used to trigger the prompt information to prompt the terminal device user to enter the password or trigger the terminal device to search whether the password information related to the AP is stored. If the terminal device user enters the password or the terminal device determines that the password information related to the AP is stored, the terminal device determines that the user group to which the user of the terminal device belongs is a contracted user group; if the terminal device user does not enter the password and the terminal device determines that the password information related to the AP is not stored, the terminal device determines that the user group to which the user of the terminal device belongs is a non-contracted user group.

[0076] There may be other ways for a terminal device to determine the user group to which the user of the terminal device belongs, and this embodiment of the present application does not limit this.

[0077] In one possible implementation, the first information includes multiple access category (AC) values, each AC value corresponding to access information of multiple user groups. The AC value is generated based on the service type of the terminal triggering the data transmission or the reason for initiating the request, and is used to instruct the terminal device to determine the numerical 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 the following: a unified access control barring parameter uac-BarringFactor, a unified access control barring time uac-BarringTime, or a unified access barring identifier uac-BarringForAccessIdentity. In addition to the above parameters, the access control parameters may also include other parameters, which are not limited in the embodiments of the present application.

[0078] uac-BarringFactor is used to compare with the random number generated by the terminal device. If the preset requirements are met, access control is completed. The preset requirement can be to meet the size of the random number generated by the terminal device is larger than uac-BarringFactor, or to meet the value of the random number of the terminal device is smaller than uac-BarringFactor, which is not limited in the embodiment of the present application. The success rate of terminal device access control can be changed by changing the value of uac-BarringFactor. For example, the preset requirement is to meet the size of the random number generated by the terminal device is larger than uac-BarringFactor, and the random number that the terminal device can generate is within 0 to 100. If the value of uac-BarringFactor is 50, the success rate of access control for the terminal device is 50%; if the value of the BarringFactor is 75, the success rate of access control for the terminal device is 25%. Therefore, when the AP cell is in hybrid mode, under the same AC value, the probability that the BarringFactor corresponding to the subscribed user group enables the terminal device to access the network is greater than the probability that the BarringFactor corresponding to the non-subscribed user group enables the terminal device to access the network. When the AP cell is in network shared cell mode, under the same AC value, the BarringFactor corresponding to the contracted user group enables the probability of the terminal device accessing the network to be greater than the BarringFactor corresponding to the non-contracted user group, and the BarringFactor corresponding to the high-level contracted user group enables the terminal device to access the network to be greater than the BarringFactor corresponding to the low-level contracted user group.

[0079] uac-BarringTime is the time required to fall back when the terminal device access control fails, that is, no connection request can be initiated within the uac-BarringTime. If the AP cell is in mixed mode, and in the same AC value, the uac-BarringTime corresponding to the contracted user group is less than the uac-BarringTime corresponding to the non-contracted user group. If the cell is in network sharing cell mode, in the same AC value, the uac-BarringTime corresponding to the contracted user group is less than the uac-BarringTime corresponding to the non-contracted user group, and the uac-BarringTime corresponding to the higher-level contracted user group is less than the lower-level contracted user group.

[0080] uac-BarringForAccessIdentity contains an identifier that prohibits some terminal devices from accessing. 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 in mixed mode, and in the same AC value, the number of uac-BarringForAccessIdentity corresponding to the contracted user group is less than the uac-BarringForAccessIdentity corresponding to the non-contracted user group. If the cell is in network sharing cell mode, in the same AC value, the uac-BarringForAccessIdentity corresponding to the contracted user group is less than the uac-BarringForAccessIdentity corresponding to the non-contracted user group, and the uac-BarringForAccessIdentity corresponding to the higher-level contracted user group is less than the lower-level contracted user group.

[0081] In another possible implementation, the access information includes random access information. The random access information includes one or more of the following: random access resources, random access parameters, or access mode indication information.

[0082] Among them, the random access resource includes one or more of the following resources: random access transmission opportunity RO resources, uplink shared channel transmission opportunity PO resources, random access channel PRACH resources or uplink transmission resources. The random access resource is specifically: time domain and / or frequency domain resources for preamble transmission, Preamble list, PUSCH transmission time domain and / or frequency domain resources, uplink transmission resources for packet transmission. In addition, the random access resource may also include other resources, which are not limited in the embodiment of the present application. If the AP cell mode is a mixed mode cell, the random access resources corresponding to the subscribed user group are additionally configured, and the resources are different from the random access resources corresponding to the non-subscribed user group. If the AP cell is a network shared cell, different random access resources are configured for different subscribed user groups, and one implementation method may be that the random access resources corresponding to the high-level subscribed user group are more than the random access resources corresponding to the low-level subscribed user group. Through the different access resources used by the terminal device, the access network device can determine which user group the terminal device belongs to, and the user access request can be processed preferentially for the high-level subscribed user group. In addition, the random access resource may also include other resources, which is not limited in the embodiment of the present application.

[0083] The random access parameter includes one or more of the following: a power ramp-up parameter, a back-off parameter or a maximum number of transmission times.

[0084] The power climbing parameter is used when the terminal device fails to access randomly and then initiates random access again. The power of sending messages will be increased based on the value of the power climbing parameter, so as to increase the probability of successfully sending information. The larger the power climbing parameter, the greater the increase in the sending power and the greater the probability of successfully sending information; the smaller the power climbing parameter, the smaller the increase in the sending power and the smaller the probability of successfully sending information. If the AP cell mode is a mixed mode cell, the power climbing parameter corresponding to the contracted user group will be greater than the power climbing parameter corresponding to the non-contracted user group. If the AP cell is a network sharing cell, the power climbing parameter corresponding to the contracted user group will be greater than the power climbing parameter corresponding to the non-contracted user group, and the power climbing parameter corresponding to the contracted user group with a higher level will be greater than the power climbing parameter of the contracted user group with a lower level.

[0085] The fallback parameter is used to wait for the fallback time to be determined based on the fallback parameter when the terminal device initiates random access again after random access fails. The larger the fallback parameter, the longer the fallback time, and the smaller the fallback parameter, the shorter the fallback time. If the AP cell mode is a mixed mode cell, the fallback parameter corresponding to the contracted user group will be smaller than the fallback parameter corresponding to the non-contracted user group. If the AP cell is a network shared cell, the fallback parameters corresponding to the contracted user group are all smaller than the fallback parameters corresponding to the non-contracted user group, and the fallback parameters corresponding to the higher-level contracted user group are smaller than the fallback parameters of the lower-level contracted user group.

[0086] The maximum number of transmissions is used to stop the relevant random access process, mainly the four-step random access process, when the terminal device fails randomly for many times; or use the two-step random access process, and fall back to the four-step random access process after multiple failures. The larger the value, the more random access processes the terminal device can try, and the greater the access probability. If the AP cell mode is a mixed mode cell, the maximum number of transmissions corresponding to the contracted user group will be greater than the maximum number of transmissions corresponding to the non-contracted user group. If the AP cell is a network sharing cell, the maximum number of transmissions corresponding to the contracted user group can be greater than the maximum number of transmissions corresponding to the non-contracted user group, and the maximum number of transmissions corresponding to the high-level contracted user group is greater than the maximum number of transmissions corresponding to the low-level contracted user group.

[0087] In addition, the access parameters may also include other parameters, which are not limited in the embodiments of the present application.

[0088] Among them, the access method indication information is used to instruct the terminal device to determine to access the network using a first access method based on preset requirements, and the first access method is any one of the following methods: four-step random access, two-step random access or small packet transmission.

[0089] The steps of four-step random access are as follows: Figure 3As shown: the terminal device uses random access resources to send Msg1 to the access network device, and Msg1 includes a preamble; the terminal device receives Msg2 sent by the access network device, and the second information includes response information corresponding to the preamble; the terminal device sends Msg3 to the access network device, and Msg3 includes an RRC message; the terminal device receives Msg4 sent by the access network device, and Msg4 includes response information to Msg3. In 5G NR, the terminal device air interface has three states, namely idle state, inactive state and connected state. The terminal device in the idle state is not connected to the base station, and only needs to periodically initiate location updates, cell selection and reselection processes, and receive paging, etc.; the terminal device in the inactive state does not need to notify the base station when moving within the cell; the terminal device in the connected state remains connected to the network, and the network can schedule uplink and downlink data for the terminal device. If a terminal device in a non-connected state needs to transmit data with an access network device, it needs to migrate to the connected state through random access. In the four-step random access, if the terminal device is in the connected state, the terminal can carry uplink data when sending Msg3; when the terminal device is in the non-connected state, it cannot carry uplink data and needs to complete random access before sending data.

[0090] The steps of two-step random access are as follows Figure 4 As shown: the terminal device sends MsgA to the access network device, and MsgA includes the preamble and RRC message. If the terminal device is in the connected state, MsgA can include data; the access network device sends MsgB to the terminal device, and MsgB includes the response information to MsgA. If during the two-step random access process, the network device only receives the preamble sent by the terminal device, then the network device only replies with the response information of the preamble, and the terminal device will change the random access mode to four-step random access. If the terminal device is in the idle state or inactive state, the MsgA sent by the terminal device during the two-step random access process can only include RRC messages, not data, so the terminal device needs to send data after completing the random access process. MsgA in the two-step random access includes the contents of Msg1 and Msg3 in the four-step random access, so the two-step random access can reduce the delay and signaling overhead compared to the four-step random access.

[0091] The steps of packet transmission are as follows Figure 5As shown: the terminal device uses the pre-configured UL resource (PUR) or pre-configured uplink resource of the access network device to send the first information, which includes the preamble, RRC message and data. If the time advance TA timer has not timed out or the TA state is valid, the first information may not include the preamble; the access network device sends the second information, which includes the response information of the data. Small packet transmission allows the terminal device to directly send data when it is not connected, effectively improving the efficiency of the terminal device accessing the network.

[0092] 202. The terminal device obtains, from the access information corresponding to the multiple user groups, first access information corresponding to the user group to which the user of the terminal device belongs.

[0093] In a possible implementation, step 202 specifically includes: the terminal device generates a first AC value; the terminal device obtains an access control parameter corresponding to the user group to which the user of the terminal device belongs from the access information corresponding to the first AC value in the first information. The following uses a specific example to introduce a method for the terminal device to obtain the access control parameter corresponding to the user group to which the user of the terminal device belongs.

[0094] When the AP cell where the terminal device is located is a mixed mode cell, and the preset requirement is to meet the size of the random number generated by the terminal device is greater than the uac-BarringFactor. If the AC value generated by the terminal device is 1, the terminal device can determine the two parameters uac-BarringTime and uac-BarringFactor corresponding to the AC value of 1 based on Table 1. If the user group to which the user of the terminal device belongs is a contracted user group, the terminal device can determine the first access parameter uac-BarringTime to be A1 and uac-BarringFactor to be C1; if the user group to which the user of the terminal device belongs is a non-contracted user group, the terminal device can determine the first access parameter uac-BarringTime to be B1 and uac-BarringFactor to be D1. Among them, A1 is less than B1, and C1 is less than D1. It can be seen that the uac-BarringTime corresponding to the contracted user group is less than the uac-BarringTime of the non-contracted user group, and the uac-BarringFactor corresponding to the contracted user group is less than the uac-BarringFactor corresponding to the non-contracted user group. Therefore, the success rate of accessing the network by terminal devices whose users are grouped as contracted user groups is greater than that of accessing the network by terminal devices whose users are grouped as non-contracted user groups. This method can help improve the success rate of contracted users 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, p95; the available values ​​of uac-BarringTime are: s4, s8, s16, s32, s64, s128, s256, s512.

[0095] Table 1

[0096]

[0097] 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 greater than the uac-BarringFactor, and the level of the subscribed user group 1 is higher than that of the subscribed user group 2. If the AC value generated by the terminal device is 1, the terminal device can determine the two parameters uac-BarringTime and uac-BarringFactor corresponding to the AC value 1 based on Table 2. If the user group to which the user of the terminal device belongs is the subscribed user group 1, the terminal device can determine the first access parameter uac-BarringTime to be A1 and the uac-BarringFactor to be D1; if the user group to which the user of the terminal device belongs is the subscribed user group 2, the terminal device can determine the first access parameter uac-BarringTime to be B1 and the uac-BarringFactor to be E1; if the user group to which the user of the terminal device belongs is the non-subscribed user group, the terminal device can determine the first access parameter uac-BarringTime to be C1 and the uac-BarringFactor to be F1. Among them, A1 is less than B1 less than C1, and D1 is less than E1 less than F1. It can be seen that the uac-BarringTime corresponding to the high-level contracted user group is smaller than the uac-BarringTime corresponding to the low-level contracted user group, which is smaller than the uac-BarringTime corresponding to the non-contracted user group, and the uac-BarringFactor corresponding to the contracted user group is smaller than the uac-BarringFactor corresponding to the low-level contracted user group, which is smaller than the uac-BarringFactor corresponding to the non-contracted user group. Therefore, the success rate of the terminal device in the user group of contracted user group 1 accessing the network is greater than the terminal device in the user group of contracted user group 2, and also greater than the terminal device in the user group of non-contracted user group. This method can help improve the success rate of high-level contracted users 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, p95; the available values ​​of uac-BarringTime are: s4, s8, s16, s32, s64, s128, s256, s512.

[0098] Table 2

[0099]

[0100] In another possible implementation, step 202 specifically includes: the terminal device obtains the random access resource corresponding to the user group to which the user of the terminal device belongs from the random access information included in the access information corresponding to the multiple user groups. The following uses a specific example to introduce the manner in which the terminal device obtains the random access resource corresponding to the user group to which the user of the terminal device belongs.

[0101] When the AP cell where the terminal device is located is a mixed mode cell, the resources of random access resource A are more than the random access resource B, and the level of contracted user group 1 is higher than that of contracted user group 2. If the user group to which the user of the terminal device belongs is a contracted user group, the random access resource corresponding to the terminal device can be determined to be random access resource A based on Table 3; if the user group corresponding to the user of the terminal device is a non-contracted user group, the random access resource corresponding to the terminal device can be determined to be random access resource B based on Table 3. Since the resources of random access resource A are more than the random access resource B, the random access resources of the terminal device whose user group is a contracted user group will be more than the random access resources of the terminal device whose user group is a non-contracted user group. Therefore, the success rate of the terminal device whose user group is a contracted user group to access the network is greater than that of the terminal device whose user group is a non-contracted user group. In this way, it is beneficial to improve the success rate of contracted users accessing the network.

[0102] Table 3

[0103] User Grouping Random access resources Subscriber Grouping Random access resource A Non-subscriber group Random access resource B

[0104] When the AP cell where the terminal device is located is a network sharing cell, the random access resource A is greater than the random access resource B and greater than the random access resource C, and the level of the contracted user group 1 is higher than that of the contracted user group 2. If the user group to which the user of the terminal device belongs is the contracted user group 1, the random access resource corresponding to the terminal device can be determined to be the random access resource A based on Table 4; if the user group to which the user of the terminal device belongs is the contracted user group 2, the random access resource corresponding to the terminal device can be determined to be the random access resource B based on Table 3; if the user group to which the user of the terminal device belongs is the non-contracted user group, the random access resource corresponding to the terminal device can be determined to be the random access resource C based on Table 3. Since the resources of random access resource A are greater than the resources of random access resource B, which are greater than the resources of random access resource C, the resources of the terminal devices of the user grouped as contracted user group 1 will be greater than the resources of the terminal devices of the user grouped as contracted user group 2, which are greater than the resources of the terminal devices of the user grouped as non-contracted user groups. Therefore, the success rate of the terminal devices of the user grouped as contracted user group 1 in accessing the network is greater than the terminal devices of the user grouped as contracted user group 2, and is also greater than the terminal devices of the user grouped as non-contracted user groups. This method is conducive to improving the success rate of high-level contracted users in accessing the network.

[0105] Table 4

[0106] User Grouping Random access resources Subscriber Group 1 Random access resource A Subscriber Group 2 Random access resource B Non-subscriber group Random access resource C

[0107] In another possible implementation, step 202 specifically includes: the terminal device obtains the random access parameter corresponding to the user group to which the user of the terminal device belongs from the random access information included in the access information corresponding to the multiple user groups. The following uses a specific example to introduce the manner in which the terminal device obtains the random access parameter corresponding to the user group to which the user of the terminal device belongs.

[0108] When the AP cell where the terminal device is located is a mixed mode cell, if the user group to which the user of the terminal device belongs is a contracted user group, the power climbing parameter determined by the terminal device can be determined to be A and the fallback parameter can be determined to be C based on Table 5; if the user group to which the user of the terminal device belongs is a non-contracted user group, the power climbing parameter determined by the terminal device can be determined to be B and the fallback parameter can be determined to be D based on Table 5. 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 climbing parameter of the contracted user group is higher than the power climbing parameter corresponding to the non-contracted user group, and the fallback parameter corresponding to the contracted user group is lower than the fallback parameter corresponding to the non-contracted user group. Therefore, the success rate of the terminal device whose user group is a contracted user group to access the network again is greater than that of the terminal device whose user group is a non-contracted user group. In this way, it is beneficial to improve the success rate of contracted users accessing the network.

[0109] Table 5

[0110] User Grouping Power ramp parameters Fallback Parameters Subscriber Grouping A C Non-subscriber group B D

[0111] When the AP cell where the terminal device is located is a network sharing cell, the level of the contracted user group 1 is higher than that of the contracted user group 2. If the user group to which the user of the terminal device belongs is the contracted user group 1, the power climbing parameter corresponding to the terminal device can be determined to be A and the fallback parameter can be D based on Table 4; if the user group to which the user of the terminal device belongs is the contracted user group 2, the power climbing parameter corresponding to the terminal device can be determined to be B and the fallback parameter can be E based on Table 3; if the user group to which the user of the terminal device belongs is the non-contracted user group, the power climbing parameter corresponding to the terminal device can be determined to be C and the fallback parameter can be F based on Table 3. In Table 6, the value of A is greater than the value of B, which is greater than the value of C, and the value of E is less than the value of F, which is less than the value of G. It can be seen that the power climbing parameter corresponding to the contracted user group 1 is higher than the power climbing parameter corresponding to the contracted user group 2 and higher than the non-contracted user group, and the fallback parameter corresponding to the contracted user group 1 is lower than the fallback parameter corresponding to the contracted user group 2 and lower than the fallback parameter corresponding to the non-contracted user group. Therefore, the success rate of the terminal device whose user group is the contracted user group 1 to access the network is greater than the terminal device whose user group is the contracted user group 2, and is also greater than the terminal device whose user group is the non-contracted user group. In this way, it is beneficial to improve the success rate of high-level contracted users accessing the network.

[0112] Table 6

[0113] User Grouping Power ramp parameters Fallback Parameters Subscriber Group 1 A D Subscriber Group 2 B E Non-subscriber group C F

[0114] In another possible implementation, the step 202 specifically includes: the terminal device obtains the access mode indication information corresponding to the user group to which the user of the terminal device belongs from the random access information included in the access information corresponding to the multiple user groups; the terminal device determines that the terminal device will use the first access mode to access the network based on the indication information. The specific steps for the terminal device to determine that the terminal device will use the first access mode to access the network based on the indication information are as follows: if the group to which the user of the terminal device belongs is a contracted user group, the terminal device uses two-step random access or small packet transmission to access the network; if the group to which the user of the terminal device belongs is a non-contracted user group, the terminal device needs to determine whether the preset requirements are met, if not, the four-step random access method is used to access the network, and if so, the two-step random access or small packet transmission method is used to access the network. Since the speed of accessing the network can be effectively improved by using the two-step random access or small packet transmission method, this implementation method is conducive to improving the speed of contracted users accessing the network.

[0115] The preset requirements include whether the cell signal value measured by the terminal device is greater than the preset threshold and / or whether the data to be sent by the terminal device is a preset data service type, such as the logical channel identifier LCH ID or the data radio bearer identifier DRB ID of the data to be transmitted or whether it is positioning data to determine whether the configuration requirements are met before the small packet transmission method can be used. The preset requirement can also be whether the amount of data to be transmitted is less than a certain threshold. If it is, the small packet transmission method can be used. In this way, it is avoided that the terminal device fails to attempt two-step random access or small packet transmission multiple times due to poor signals, occupying the resources of other users, and at the same time, data services with high latency requirements can reduce the latency of data transmission of such services by adopting two-step random access or small packet transmission to meet the corresponding needs of data services. In addition to the requirements described above, the preset requirements may also have other requirements, such as requiring the data sent by the terminal device not to exceed the preset threshold, etc., which is not limited in the embodiments of the present application.

[0116] In another possible implementation, the specific steps for a terminal device to determine, based on the acquired indication information, that the terminal device will access the network using the first access method are as follows: If the user group of the terminal device is a contracted user group, and the indication information of the contracted group indicates that the terminal device can ignore one or more preset requirements, including ignoring the threshold requirements and / or DRB configuration requirements and / or data volume threshold requirements for using the corresponding access method, and directly use two-step random access or small packet transmission methods.

[0117] 203. The terminal device accesses the network based on the first access information.

[0118] Through the method described in the embodiment of the present application, a terminal device receives first information sent by an access network device, and the first information includes access information corresponding to multiple user groups; the terminal device obtains the first access information corresponding to the user group to which the user of the terminal device belongs from the access information corresponding to the multiple user groups; the terminal device accesses the network based on the first access information, which is conducive to improving the probability of successful access to the network by the contracted user.

[0119] See also Figure 6 , Figure 6 6 is a flowchart of a network access method provided by an embodiment of the present application. The network access method includes steps 601 to 605. Among them:

[0120] 601. An access network device broadcasts first information, where the first information includes access information corresponding to multiple user groups.

[0121] 602. The terminal device obtains, from the access information corresponding to the multiple user groups, first access information corresponding to the user group to which the user of the terminal device belongs.

[0122] 603. The terminal device accesses the network based on the first access information.

[0123] The specific implementation of steps 201 to 203 is the same as the specific implementation of steps 601 to 603 above, and will not be described in detail here.

[0124] 604. If the access network device determines that the user group to which the user of the terminal device belongs is a non-subscribed user group and the terminal device accesses the network based on the access information corresponding to the subscribed user group, the access network device sends penalty information to the terminal device.

[0125] In the embodiment of the present application, when the terminal device and the access network device successfully establish a connection and exchange data, 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. If the terminal device is a non-contracted user, but accesses the network based on the access information corresponding to the contracted user group, the non-contracted user will occupy the resources of the contracted user, reducing the probability of the contracted user successfully accessing the network. Therefore, the access network device will send penalty information to the terminal device to enable the terminal device to activate the penalty mechanism.

[0126] In one achievable manner, if the AP cell is a network sharing cell, if the access network device determines that a terminal device of a low-level subscriber group uses access information corresponding to a high-level subscriber group for random access, the access network device will send penalty information to the terminal device. In this way, it is helpful to prevent the resources of high-level subscribers from being used by low-level subscribers.

[0127] 605. The terminal device initiates a penalty mechanism.

[0128] In an embodiment of the present application, the penalty mechanism includes one or more of the following mechanisms: releasing the radio resource control RRC, the terminal device will not be able to initiate a connection request within a preset time, or the level of the user group to which the user of the terminal device belongs is reduced. In addition to the penalty mechanism mentioned above, other penalty mechanisms may also be used, and the embodiment of the present application does not limit this. In this way, it is helpful to prevent the resources of the contracted user from being used by non-contracted users.

[0129] See also Figure 7 , Figure 7 A schematic diagram of the structure of a communication device according to an embodiment of the present application is shown. The device may be a terminal device, or a device in a terminal device, or a device that can be used in conjunction with a terminal device. Figure 7 The communication device shown may include a processing unit 701 and a communication unit 702. The processing unit 701 is used to perform data processing. The communication unit 702 integrates a receiving unit and a sending unit. The communication unit 702 may also be called a transceiver unit. Alternatively, the communication unit 702 may be split into a receiving unit and a sending unit. The processing unit 701 and the communication unit 702 below are similar, and will not be described in detail below.

[0130] The communication unit 702 is used to receive the first information sent by the access network device, wherein the first information includes access information corresponding to multiple user groups; the processing unit 701 is used to obtain the first access information corresponding to the user group to which the user of the terminal device belongs from the access information corresponding to the multiple user groups; the processing unit 701 is also used to access the network based on the first access information.

[0141] Optionally, the multiple user groups include a non-subscribed user group and / or multiple subscribed user groups.

[0142] In one possible implementation, the communication unit 701 is also used to receive penalty information sent by the access network device; the processing unit 702 is also used to start a penalty mechanism, which includes releasing the radio resource control RRC and / or the terminal device will not be able to initiate a connection request within a preset time.

[0143] See also Figure 7 , Figure 7 A schematic diagram of the structure of a communication device according to an embodiment of the present application is shown. The device may be an access network device, or a device in an access network device, or a device that can be used in conjunction with an access network device. Figure 7 The communication device shown may include a processing unit 701 and a communication unit 702. Among them:

[0144] The communication unit 702 is used to broadcast first information, where the first information includes access information corresponding to multiple user groups.

[0145] Based on the method described in the second aspect, the access information corresponding to the contracted user group is different from the access information corresponding to the non-contracted user group. By making the access information corresponding to the contracted user group superior to the non-contracted user group, it is beneficial to increase the probability of successful network access for the contracted user.

[0157] In one possible implementation, the processing unit 701 is used to determine whether the user group to which the user of the terminal device belongs is a non-contracted user group and the terminal device accesses the network based on the access information corresponding to the contracted user group; the communication unit 702 is also used to, if it is determined that the user group to which the user of the terminal device belongs is a non-contracted user group and the terminal device accesses the network based on the access information corresponding to the contracted user group, the access network device sends penalty information to the terminal device, and the penalty information is used to instruct the terminal device to start a penalty mechanism, and the penalty mechanism includes releasing the radio resource control RRC and / or the terminal device will not be able to initiate a connection request within a preset time.

[0158] The communication device may be, for example, a chip or a chip module. The modules included in the devices and products described in the above embodiments may be software modules or hardware modules, or may be partially software modules and partially hardware modules. For example, for each device or product applied to or integrated in a chip, each module contained therein may be implemented in the form of hardware such as circuits, or at least some of the modules may be implemented in the form of software programs, which run on a processor integrated inside the chip, and the remaining (if any) modules may be implemented in the form of hardware such as circuits; for each device or product applied to or integrated in a chip module, each module contained therein may be implemented in the form of hardware such as circuits, and different modules may be located in the same component (e.g., chip, circuit module, etc.) or in different components of the chip module, or at least some of the modules may be implemented in the form of software programs, which run on a processor integrated inside the chip module, and the remaining (if any) modules may be implemented in the form of hardware such as circuits; for each device or product applied to or integrated in a terminal, each module contained therein may be implemented in the form of hardware such as circuits, and different modules may be located in the same component (e.g., chip, circuit module, etc.) or in different components in the terminal, or at least some of the modules may be implemented in the form of software programs, which run on a processor integrated inside the terminal, and the remaining (if any) modules may be implemented in the form of hardware such as circuits.

[0159] like Figure 8 The figure shows a communication device 80 provided in an embodiment of the present application, which is used to implement the above Figure 2 and Figure 6 The device can be a terminal device or a device for a terminal device. The device for a terminal device can be a chip system or a chip in the terminal device. The chip system can be composed of a chip or can also include a chip and other discrete devices.

[0160] Alternatively, the communication device 80 is used to implement the above Figure 2 and Figure 6 The device may be an access network device or a device for an access network device. The device for an access network device may be a chip system or a chip in the access network device.

[0161] The communication device 80 includes at least one processor 820, which is used to implement the data processing function of the terminal device in the method provided in the embodiment of the present application. The device 80 may also include a communication interface 810, which is used to implement the transceiver operation of the terminal device in the method provided in the embodiment of the present application. In the embodiment of the present application, the communication interface can be a transceiver, circuit, bus, module or other type of communication interface, which is used to communicate with other devices through a transmission medium. For example, the communication interface 810 is used for the device in the device 80 to communicate with other devices. The processor 820 uses the communication interface 810 to send and receive data, and is used to implement the above method embodiment Figure 2 The method described.

[0162] The device 80 may also include at least one memory 830 for storing program instructions and / or data. The memory 830 is coupled to the processor 820. The coupling in the embodiment of the present application is an indirect coupling or communication connection between devices, units or modules, which may be electrical, mechanical or other forms, and is used for information exchange between devices, units or modules. The processor 820 may operate in conjunction with the memory 830. The processor 820 may execute program instructions stored in the memory 830. At least one of the at least one memory may be included in the processor.

[0163] When the device 80 is turned on, the processor 820 can read the software program in the memory 830, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be sent wirelessly, the processor 820 performs baseband processing on the data to be sent, and outputs the baseband signal to the radio frequency circuit (not shown in the figure). The radio frequency circuit performs radio frequency processing on the baseband signal and then sends the radio frequency signal outward through the antenna in the form of electromagnetic waves. When data is sent to the device 80, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 820. The processor 820 converts the baseband signal into data and processes the data.

[0164] In another implementation, the RF circuit and antenna may be arranged independently from the processor 820 that performs baseband processing. For example, in a distributed scenario, the RF circuit and antenna may be arranged remotely from the communication device.

[0165] The specific connection medium between the communication interface 810, the processor 820 and the memory 830 is not limited in the embodiment of the present application. Figure 8 In the embodiment, the memory 830, the processor 820 and the communication interface 810 are connected via a bus 840. Figure 8The connections between the other components are shown in bold lines, which are only for illustration and are not intended to be limiting. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 8 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.
