Description

Network access configuration method, network access method, base station and user equipment

technical field

The present invention relates to access technology in the field of wireless communication, in particular to a network access configuration method, a network access method, a base station and user equipment.

Background technique

The prevalence of mobile Internet and machine-to-machine (M2M) user equipment has triggered a large number of mobile data applications, which have greatly changed the transmission characteristics of data packets. For example, the communication of M2M user equipment causes a large number of burst small data packet services; which in turn leads to a large number of communication small data packets in the communication network, and instant messaging and more "always-on" services generate a large number of keep-alive small packets. data pack. However, the basis of the existing mobile network is based on the "network connection-oriented" approach to achieve communication; although this "connection-oriented" service approach can well solve the problem of traditional Streaming services that are more biased towards the circuit domain Efficient transmission, such as video services, file sharing, voice, etc., this communication method is difficult to adapt to the delivery of emerging small data packet services, resulting in a large amount of transmission overhead.

The small data packets here generally refer to data packets with a small data packet length, and the signaling ratio performance of these data packets is very low. The data signaling ratio here is the ratio of valid data to signaling. The signaling here includes network signaling: connection establishment signaling at the Radio Resource Connection (RRC) layer, handover signaling, resource request signaling at the network MAC layer, and measurement feedback signaling at the bottom layer. For the instant message (Instant Massage, IM) business, because it is often accompanied by the transmission of heartbeat keep-alive information to support the always-on (Always on) user experience, its signaling overhead also includes heartbeat keep-alive messages and corresponding network signaling overhead) . Obviously, if the existing cellular transmission protocol framework is continued, a large number of short burst services will inevitably bring a huge signaling burden to mobile network transmission.

The existing streaming service has an obvious session start and interruption: when the session is interrupted, it means the end of a session, and there is no obvious tailing of the service; the user equipment will naturally enter the dormant state after the session is interrupted. For a bursty service, the start and end of the session are much more ambiguous, and the data packets in the session are relatively less continuous, making it difficult to distinguish clearly whether the interval between data packets of a user equipment occurs within a session. Still one session away. And understand that the network will consider whether it is necessary to release a connection first to save power for the user equipment according to the length of time between data packets. When the session and data packets are blurred, the network-oriented connection of the mobile user equipment is released from one session at a time. , to a packet once, and the amount of data completed by one connection changes from the amount of data in one session to the amount of data in one packet. In addition, in the Long Term Evolution (LTE) system, a connection release includes security activation, dedicated signaling and data bearer establishment, involving more than 10 signaling interactions, and can generate about 256 bytes of signaling load. Considering the short-burst feature of the instant messaging small data packets, the signaling overhead of transmitting unit data obviously increases. However, it is also difficult for the user equipment to switch back and forth between the sleep state and the active state for a long time, and it is also difficult to realize effective sleep power saving.

Communication protocol version 12 (R12 for short) of the 3rd Generation Partnership Project (3GPP), communication protocol for enhanced Machine Type Communication (eMTC) and communication protocol version 13 (R13 for short) , all of which provide optimized solutions for small data services using Machine Type Communication (MTC). The weak mobility and single service of the main MTC weaken the mobile support signaling and the communication signaling carried by it. The transmission of the small data packet is completed through a default bearer and carried by Network Attached Storage (NAS) signaling. This solution is proposed to adapt to the existing LTE protocol framework as much as possible in consideration of high-level protocols. Essentially, the current MTC solution considers a scheduling solution. However, it is found through research that, in specific business and network scenarios, the scheduling scheme is not necessarily the most effective.

detailed description

The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Embodiment one:

As shown in Figure 1, this embodiment provides a network access configuration method, including:

Step S110: Obtain network status information;

Step S120: configure network access policies and corresponding access resources according to the network status information, and form network access policies and access resource configuration information;

Step S130: Send the access resource configuration information and the network access policy to the user equipment.

The network access configuration method described in this embodiment may be a method applied in a base station. The network access configuration method described in this embodiment may also be a network access configuration method applied in various wireless networks.

In step S110, the base station acquires network status information, which can be used to represent the current idle or busy status of the network, and can also be used to represent the ratio relationship between the current network available resource quantity and access demand, etc.

In step S110 of this embodiment, the base station can obtain the network status information according to a predetermined time interval, for example, periodically obtain the network status information; specifically, periodically read information such as network load or network load rate .

In step S120, the base station may determine an access resource configuration and a network access strategy suitable for the current network condition according to the network condition information. In this way, the base station can complete the configuration of radio resources, and control the access of user equipment (User Equipment, UE) according to the network access policy. The access resource configuration information may be access resource configuration information corresponding to the access resource configuration result of the base station. The network access policy may include various access schemes formulated correspondingly under different network conditions. The access scheme here may include various parameters restricting UE access, such as access mode and access format parameters.

In step S130, the access resource configuration information and network access policy determined in step S120 are sent to the UE, and the UE performs network access according to the access resource configuration information and network access policy received from the base station, or Only the network status information is sent to the UE, so that after the UE receives the network status information, it determines the The network access configuration and network access strategy applicable to the current network conditions, and then the network access is performed according to the network access configuration and network access strategy determined by the query.

In this embodiment, the network access policy may be represented by a network access policy mapping table, and Table 1 is an example of the network access policy mapping table:

Service type and data packet length Network access method Service type 1 and data packet length 1 Access method one Service type 2 and data packet length 2 Access method two Service type 2 and data packet length 3 Access method three

Table 1

In this embodiment, the access resource configuration may include configuration of random access sequences, including configuration of uplink transmission resources. For example, one or more time-frequency resources are allocated to corresponding service types for data transmission. According to the access resource configuration information and the types of services it needs to send to, the UE can determine which time-frequency resources to use for data transmission. For example, according to the current network status information, the base station determines that frequency band A is used to transmit ultra-reliable and low latency communication (Ultra-Reliable and Low Latency Communication, URLLC), and forms the corresponding access resource configuration information; the UE is receiving When the access resource configuration information is obtained, when the user needs to send the URLLC service, the frequency band A is used to upload data.

In a word, this embodiment provides a method for dynamically determining access resource configuration and network access strategy based on current network status information, so that the most suitable network access mode can be determined for more effective Use wireless resources to improve the efficiency of data transmission.

The network status information includes network load status information. In this embodiment, the network load status information may include a network load value or a network load rate. In this embodiment, the network load value may be the current load of a cell or a base station; the network load rate may be understood as a ratio of the network load value to the maximum load of a cell or a base station.

The network access policy includes an access scheme and conditions for adopting the access scheme. The access scheme includes: an access method; wherein, the access method is used to instruct the user equipment to adopt an access method.

The access scheme includes an access method;

The access method includes: at least one of a scheduling-free transmission method, a short burst access method, a pulse scheduling access method, and a backoff access method;

Among them, the scheduling-free transmission mode is: when the base station does not schedule dedicated resources for the user equipment, the user equipment directly seizes resources for data transmission access mode;

The short burst access mode is: when the base station does not schedule resources for the user equipment, the user equipment preempts resources to perform access reason and/or data packet length indication and/or user equipment identification and/or cache status report and other data packets The access method of information transmission;

The pulse scheduling access mode is: an access mode in which the base station schedules dedicated resources for the user equipment;

The back-off access mode is: back off when an access conflict occurs, and select the pulse-scheduled access access mode by default after the back-off.

Access methods can be divided into two categories, namely the first type of access method and the second type of access method; among them, the first type of access method and the second type of access method can include any of the above-mentioned access methods input method. For example, both the first type of access mode and the second type of access mode may include a scheduling-free transmission mode and the like. The difference between the first type of access method and the second type of access method is that before accessing the base station, the user equipment needs to send a synchronization signal to synchronize with the base station before using the first type of access method; while using the second type of access method When accessing in the mode, there is no need to send a synchronization signal for synchronization. For example, when user equipment A uses the scheduling-free transmission in the first type of access mode to access, it first sends a synchronization signal to the base station, and then uses the scheduling-free transmission mode to perform access and data transmission. If the user equipment A uses the scheduling-free transmission in the second type of access mode for access, it directly uses the scheduling-free transmission mode for access and data transmission.

The access scheme also includes an access format parameter;

The access format parameter can at least be used to indicate the information that needs to be carried during access; the information that needs to be carried during access includes: at least one of them. In addition, the access format parameter further includes: at least one of the modulation and coding scheme of the information and the number of resources occupied by the information.

In this embodiment, there may not be a fixed correspondence between the access mode and the access format parameter, and different access modes may correspond to the same access format for access. For example, both the pulse scheduling access method and the backoff access method can send data packets formed by the same modulation and coding method.

Of course, different access methods and resource configuration information are also the same, that is, different access methods can share the same communication resources for communication.

In this embodiment, the access mode may include a short burst access mode, a pulse scheduling access mode, or a backoff access mode, and the like. The pulse scheduling access mode here is: an access mode in which the base station schedules dedicated resources for the user equipment. The short burst access mode may include and carry an access reason and/or a data packet length indication. In the scheduling-free transmission mode here, the UE does not need the base station to directly seize communication resources for data transmission without the base station not specifically participating in resource scheduling for the UE or sending scheduling information to the UE.

Combined with the above-mentioned network access policy mapping table, the following provides several corresponding relationship tables that can characterize access schemes and adoption conditions.

Table 2 is the determined network access strategy when the current load rate is lower than A%;

Table 3 is the determined network access strategy when the current load rate is lower than B%;

Table 4 is the determined network access strategy when the current load rate is lower than C%;

Table 5 shows the determined network access strategy when the current load rate is higher than C%.

The value of said A can be 10, 15 or 25 and other values; the value of said B can be 50, 60 or 55 and other values; the value of said C can be 70 or 75 and other values; in short , the above-mentioned values of A, B, and C are just an example, and are not limited to the above-mentioned values, and the above-mentioned values can also be adjusted as required during specific implementation. Combining the contents of Table 2 to Table 4, the above-mentioned values of A, B, and C satisfy that A is less than B, and B is less than C.

Table 2

table 3

table 3

business type access plan Non-Low Latency URLLC backoff access Low Latency URLLC Pulse Scheduling Access

Table 4

The scheduling-free data transmission in Table 2 and Table 3 means that the base station does not schedule dedicated resources for the UE, and the UE directly seizes wireless resources for data transmission.

The burst-scheduled access in Table 2 to Table 4 means: the burst-scheduled access may include an access manner in which the base station schedules dedicated resources for the user equipment.

The back-off access in Table 4 may include random back-off access, where the random back-off means that the UE performs random access again after back-off for a length of time.

The values of A1, B1 and C1 in Table 2 to Table 4 can be any value. In this embodiment, the value of A1 can be 30, and the values of B1 and C1 can be 10. However, the values of A1, B1 and C1 are not limited to the above-mentioned values, usually the A1 is greater than the B1.

In this embodiment, the non-low-latency URLLC and the low-latency URLLC represent two different service types of URLLC, and the service delay requirement of the low-latency URLLC is higher than that of the non-low-latency URLLC Require. Whether a URLLC service is a low-latency URLLC or a non-low-latency URLLC can be classified by comparing the delay requirement of the URLLC service with a preset delay threshold.

It can be seen from Table 2 that when the network load rate is low and the length of the data packet is small, the data packet can be transmitted without scheduling. If the network load rate is low, short-burst access can be used for data packets with increased data packet length. On the one hand, it can meet the requirements of large number of data packets for small data packets, large number of transmission requirements, and the limitation of transmission delay blocks. Features, for data packets with large data packet length, short burst access is allowed, which can meet the characteristics of high data transmission efficiency.

From Table 3 and Table 4, it can be seen that for low-latency service types, access methods with low latency are preferred for access; for non-low-latency service types, access methods with longer delays can be selected for access . In this way, some service types do not distinguish the time delay of different service types, adopt a unified access mode, access conflicts and low access efficiency.

As a further improvement of this embodiment, the step S120 may include:

The access format parameter further includes: at least one of a modulation and coding scheme of information and a resource quantity occupied by information.

In this embodiment, the access format parameter also defines the information format such as the data length of the information, the modulation and coding method, and the number of resources occupied by the information. After receiving the above information format, the UE transmits uplink data according to the above information format. For example, the uplink data is divided into the above-mentioned data length, and the uplink data is coded by using the above-mentioned modulation and coding scheme. The data length here may be the amount of data. In this way, after receiving the uplink data sent by the UE according to the above information, the base station can quickly demodulate and decode the information, improve the information decoding and demodulation efficiency of the base station, and reduce the system resources consumed by the base station due to demodulation and decoding .

When the base station sends data to the UE, any one of broadcast, multicast or unicast can be used. In this embodiment, step S130 can be selected as: using a broadcast message or a multicast message or a random access response message, Send the access resource configuration information and the network access policy to the user equipment.

In this embodiment, a random access response may be used to send the above access resource configuration information and network access policy. Of course, in actual implementation, the base station may also use user-specific information such as radio resource control (Radio Resource Controller, RRC) information to send the information to be sent in step S130. In a word, in a specific implementation process, there are many ways for the base station to send data to the UE, and it is not limited to any one of the above. In a specific implementation process, any combination of broadcast, multicast and unicast may also be used.

For example, if a piece of information needs to be sent to all UEs in the cell, broadcasting is preferred; if a piece of information needs to be sent to a group of UEs, groupcasting can be used; if only individual UEs need to be sent, unicasting can be used.

In this embodiment, if the network status information sent in step S130 is preferably sent by broadcast message. In order to reduce the amount of information sent by the base station, the network access policy and resource access resource configuration information of a certain service type can be sent to UEs with this service type in multicast. Therefore, in actual implementation, any two of broadcast, multicast and unicast methods can be combined to send information.

As a further improvement of this embodiment, the step S120 may include:

Compare the network load with the preset load threshold, and select the access method according to the comparison result.

For example, the comparing the network load with a preset load threshold and selecting an access mode according to the comparison result includes: if the network load is greater than the preset load threshold, determining that the user equipment is allowed to use pulse scheduling to access way to access the network. For another example, the comparing the network load with a preset load threshold and selecting an access mode according to the comparison result further includes: if the network load is less than the preset load threshold, determining that the user equipment is allowed to use data packets A data packet whose length is not greater than the first length threshold is avoided from scheduling transmission, or it is determined that the user is allowed to access the network in a short burst access mode; wherein the short burst access mode includes the reason for the user equipment to seize resources for access And/or data packet length indication and/or user equipment identification and/or access mode for data packet information transmission such as cache status report.

A specific example is given below in conjunction with the above-mentioned embodiments, assuming that the preset load thresholds include multiple load thresholds, which are respectively the following first load threshold to fourth load threshold.

The step S120 may include:

If the network load is greater than the first load threshold, it is determined to use backoff when an access conflict occurs, and after the backoff, the pulse scheduling access method is selected by default for access; wherein, the pulse scheduling access method is: the base station schedules for the user equipment Access to exclusive resources.

Further, if the network load is greater than the second load threshold and less than the first load threshold, it is determined that the user equipment is allowed to use the pulse scheduling access mode to access the network; wherein the pulse scheduling access mode is: The base station schedules an access mode of exclusive resources for the user equipment.

Still further, if the network load is greater than the third load threshold and less than the second load threshold, it is determined that the user equipment is allowed to use a data packet with a data packet length not greater than the first length threshold in a short burst access mode accessing the network; wherein, the short burst access mode includes an access mode carrying an access reason and/or a data packet length indication.

In addition, if the network load is greater than the fourth load threshold and less than the third load threshold, it is determined that the user equipment is allowed to use a data packet with a data packet length not greater than the second length threshold to access in a short burst access mode. network.

In the above embodiment, the first load threshold is greater than the second load threshold; the second load threshold is greater than the third load threshold, and the third load threshold is greater than the fourth load threshold;

The first length threshold is less than the second length threshold.

In this embodiment, the network load may be a load value or a load rate. In this embodiment, a solution of how to determine the network access policy is specifically provided, which has the characteristics of simple implementation.

In short, the network access configuration method described in this embodiment will determine the current network resource configuration and network access strategy of the network according to the network status information, so as to improve network access efficiency and use network resources more effectively.

It is worth noting that: the execution flow of the above method is not limited to the flow shown in Figure 1, if the base station sends the network status information to the UE, the base station can send the network status information to the UE after executing step S110, that is, the Step S120 and step S130 may not have a certain sequence.

Embodiment two:

As shown in Figure 2, this embodiment provides a network access method, including:

Step S210: Obtain user characteristic information and service characteristic information;

Step S220: Receive information sent by the base station; wherein, the information sent by the base station includes access resource configuration information and the network access policy;

Step S230: Perform network access according to the user feature information, the service feature information, and the information sent by the base station.

The network access method described in this embodiment may be a method applied to a UE.

The user characteristic information in step S210 may include characteristic information of the user equipment, for example, the type of the user equipment; different user equipments have different communication capabilities, and the most suitable access methods are also different. As for the service feature information, different services have different service characteristics. Some services correspond to a large amount of data and are highly contextually relevant; while some services are indeed fragmented and need to be sent by multiple small data packets.

In step S220, the information sent by the base station is received. The information sent by the base station may include network status information, and may also be access resource configuration information and network access policies. It is worth noting that there is no certain sequence between step S210 and step S220 in this embodiment, the two steps can be executed at the same time, or step S210 can be placed before step S220, or step S220 can be executed before step S210, only It is only necessary to ensure that both step S210 and step S220 are before step S230.

Therefore, in step S220, the UE may directly receive the access resource configuration information and the network access policy determined by the base station according to the network status information. The UE may also receive the network status information, and then query the corresponding relationship between the network status information stored in the UE, the access resource configuration information and the network access policy, and determine the access resource configuration information corresponding to the current network status information and network access policies.

In step S230, the network access will be performed according to the access resource configuration information and the network access strategy, so that the access of the UE can be well controlled, on the one hand, the wireless resources can be better utilized, and the resource efficiency can be improved. Effective utilization; at the same time, it can also improve the efficiency of data transmission through better utilization of resources.

In this embodiment, in step S230, the UE queries the access resource configuration information and the network access policy according to the service characteristic information of the data currently to be sent by the UE, and determines an access plan; based on the access plan Make network access. In this embodiment, the service characteristic information may include information such as the service type of the data, the delay tolerance characteristic of the data, and the length of the data packet. The delay tolerance characteristic may indicate whether the data is a low-delay service type or a non-low-delay service type.

In step S230, the user characteristic information and service characteristic information may be matched with the information received from the base station to select the most suitable access scheme.

For example, according to the service feature information, it is found that the UE currently needs to transmit multiple data packets with a small amount of data. At this time, according to the information received by the base station, it is determined that the scheduling-free transmission mode is suitable for direct transmission of data packets with a small amount of data. Through this matching in step S230, the scheduling-free transmission mode will be selected for access. Of course, the above is only an example, and cannot be interpreted as a complete limitation on step S230.

For example, the UE queries the access policy according to the current network status information, and determines the access plan corresponding to the service type requested for access; according to the current network status information, determines the access plan corresponding to the length of the data packet requested to be transmitted Scheme: According to the current network status information, determine the access scheme corresponding to the service type and data packet length requested for access.

Further, the network status information includes network load status information. The network access policy includes an access scheme and conditions for adopting the access scheme. Specifically, the access method includes: at least one of: a scheduling-free transmission method, a short burst access method, a pulse-scheduled access method, and a back-off access method; wherein, the scheduling-free transmission method is: the base station When scheduling dedicated resources for the user equipment, the user equipment directly seizes resources for data transmission access mode; the short burst access mode is: when the base station does not schedule resources for the user equipment, the reason for the user equipment to seize resources for access and /or an access mode for data packet length indication and/or user equipment identification and/or cache status report and other data packet information transmission; the pulse scheduling access mode is: an access mode in which the base station schedules dedicated resources for the user equipment; The back-off access mode is as follows: back-off is performed when an access conflict occurs, and the access mode of the pulse-scheduled access is selected by default after the back-off. Similarly, the access methods here can also be divided into the first type of access method and the second type of access method mentioned above.

At the same time, the access format parameter also includes: at least one of the modulation and coding scheme of the information and the number of resources occupied by the information.

The above configuration unit 120 determines the structure of the access plan in the network access strategy. On the one hand, it can easily determine the network access strategy suitable for the current network situation; In order to realize the corresponding transmission of different data packet length data packets and different service types.

Further, the sending unit 130 is specifically configured to send the access resource configuration information and the network access policy to the user equipment by using a broadcast message or a multicast message or a random access response message. The sending unit 130 can use various message sending methods to send network status information or access resource configuration information and network access policies to the UE. In this embodiment, the sending unit 130 specifically uses broadcast, multicast or random access It is sent by inputting a response message, which has the characteristics of simple implementation.

Further, the configuration unit 120 is specifically configured to compare the network load with a preset load threshold, and select an access mode according to the comparison result. For example, the configuring unit 120 may be specifically configured to determine that the user equipment is allowed to access the network in a burst scheduling access manner if the network load is greater than the preset load threshold. The configuration unit 120 may also be specifically configured to, if the network load is less than the preset load threshold, determine to allow the user equipment to use a data packet with a data packet length not greater than the first length threshold to avoid scheduling transmission, or to allow all The user uses a short burst access method to access the network; wherein, the short burst access method includes the reason for user equipment to seize resources for access and/or data packet length indication and/or user equipment identification and/or cache status The access method for data packet information transmission such as reports.

The access unit 230 is configured to perform network access according to the user feature information, the service feature information, and the information sent by the base station.

The user equipment described in this embodiment may be various communication user equipment, such as mobile phones and MTC equipment.

The processor may be a central processing unit, a microprocessor, a digital signal processor, or a programmable array in the user equipment. The processing circuit may be an application specific integrated circuit or the like.

In short, the UE provided in this embodiment can use an access mode or access plan suitable for the current network conditions when accessing the network, so as to achieve better utilization of wireless resources and more efficient for data transmission.

Several specific examples are provided below in combination with any of the above-mentioned embodiments:

Example one:

Devices on the network side, such as base stations, can dynamically configure different access resources and/or network access policies for user equipment according to different network states, and can pass these information to users; Different data transmission requirements, differentiated selection of access resources and/or access strategies provided by the network. The different access resources are the access resource configuration.

Step 1: Adjust access resource configuration and network access strategy according to network status information, such as network load. The network access policy may include the network access policy mapping table provided in the foregoing embodiments. The access resource configuration information and the network access policy information of the access resource configuration are sent to the user equipment separately or together, for example, by broadcast, multicast or unicast.

Step 2: UE receives the network access policy, and based on the network access policy, performs differentiated network access operations on corresponding access resources. Specifically, different service types may implement different access modes. Different service types may correspond to different data packet lengths, and may also correspond to different delay requirements. For example, the three major 5G scenarios of the fifth-generation partnership project defined by the International Telecommunication Union (ITU): enhanced mobile broadband, low-power mass connection (mMTC) and low-latency high-reliability (URLLC), may involve The different access methods proposed in this case. For another example, whether the service is accessed for the first time or re-accessed after an access failure, the information content that needs to be carried may be different between the first-time access and the non-first-time access, or the access methods used for the first-time access and re-access are different. The foregoing access methods may include a scheduling-free transmission method, a short-burst access method, a pulse-scheduled access method, a back-off access method, and the like. Short burst access may carry user identification information, user equipment buffer status (Buffer Status Report, BSR) and user data, etc.; the burst scheduling access method is similar to the traditional LTE access method, and the base station performs synchronous data scheduling transmission . Further, the different network card access policies may also include instructing the format of the information uploaded by the user equipment, so as to facilitate demodulation at the network side. The information format may include the number of bits of the information, the modulation and coding mode of the information, the number of resources occupied by the information, and so on.

The base station may use the broadcast resource information when sending data to the UE. Generally, the broadcast resource message can be sent through common system messages. Specifically, the use mode of wireless resources includes pulse-scheduled access, short-burst access carrying information such as data block size, and scheduling-free transmission directly carrying data. The broadcast message explicitly or implicitly carries the access determination method. The explicit method, for example, indicates the specific access method by using a few dedicated bits; Enter operation. In addition, the base station explicitly broadcasts burst-scheduled access and short-burst access resources at the same time, and the user equipment determines which resource to select for access based on access information or data packet length and whether certain conditions are met. For example, when the length of the user data packet is less than the predetermined threshold Pthresh, the burst access method may be selected for access or transmission. Pthresh may be the threshold value of the data packet length predefined by the network and the user equipment, or the information delivered to the user by the network through broadcast or unicast. Pthresh may be one value or a set of values corresponding to different access indications.

Of course, the base station may also use multicast to send access resource configuration information or network access policy to the user equipment. Multicast resource messaging is adapted to at least the following examples. The multicast resource allocation after user equipment access and before conflict resolution, in Long Term Evolution (LTE), is random access response message msg2; resource pool pre-scheduling for a group of users.

The backoff parameters, network load, and data packet length described in Figure 4 may be pre-access resource configuration information, broadcast information, Msg2 transfer information, or information transferred through user-specific signaling (such as RRC information, etc.), or may be Users can obtain information in different ways, such as network load is broadcast information, but data packet length and backoff parameters may be configured through user-specific signaling. In the figure, L1>L2>L3>L4, P1<P2. Note: The specific parameters used in different scenarios, such as eMBB, mMTC and URLLC, may be different. For example, for low-latency URLLC, the backoff parameter will be set smaller, or Cancel to ensure fast data transmission; of course, the same parameters can also be used to divide resources used in different scenarios through resource regulation, and always maintain low latency. URLLC scenarios have more abundant resources and lower load rates .

Example two:

As shown in Figure 5, this example provides a random access method, including:

Step S1: The base station broadcasts a network access policy; the network access policy here is determined according to current network status information.

Step S2: The user equipment determines the access mode based on the network access policy, and performs a network access operation.

Example three:

As shown in Figure 6, this example provides a random access method, including:

Step S11: the access resource configuration information multicast by the base station; the access resource configuration information here is determined according to the network status information representing the current network status.

Step S12: the user equipment judges the access mode, and performs access backoff or data transmission on the access resource corresponding to the access resource configuration information.

Example four:

As shown in Figure 7, this example provides a network access method, including:

Step S31: the user equipment sends a random access request Msg1, and generally the Msg1 may include a pilot.

Step S32: Receive a random access response message Msg2; the Msg2 may carry network access policy or network load status information, etc.; the network access policy may include backoff parameters and the length of accepted data packets. The length of the data packet accepted here may be the length of the data packet to be received by the base station.

Step S33: The user equipment determines the access method based on the configuration or the broadcast message or Msg2.

The step S33 may include:

Step S331: If the network load>L1, perform action option 1: back off randomly according to the back off parameter;

Step S332: If the network load>L2, perform action option 2: send a pulse scheduling access request; that is, perform pulse scheduling access;

Step S333: If the network load>L3, execute action option 3: use short burst access, and carry information such as user equipment identification, access reason or BSR, and the length of the information is not greater than P1 (bytes);

Step S334: If the network load is >L4, perform action option 4: use scheduling-free access, and the length of the sent data packet is not greater than P2.

Step S34: receiving scheduling information of subsequent resource scheduling of the base station, or data transmission confirmation information.
