In some embodiments of the present invention, the terminal device may also be an apparatus with a transceiving function, such as a system on a chip. The chip system may include a chip and may also include other discrete devices.

2. And (4) accessing the network equipment. The access network device in the embodiment of the present invention is a device that provides a wireless communication function for a terminal device, and may also be referred to as a Radio Access Network (RAN) device or an access network element. The access network device may support at least one wireless communication technology, such as LTE, NR, etc., among others. By way of example, access network devices include, but are not limited to: a next generation base station (generation node B, gNB), an evolved node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home node B or home node B, HNB), a base band unit (base unit, TRP), a base transceiver point (bbitting and listening point), a Transmission Point (TP), a mobile switching center, etc., in a fifth generation mobile communication system (5 th-generation, 5G).

By way of example, a system of chips may include a chip and may also include other discrete devices.

In some embodiments, the access network device may also communicate with an Internet Protocol (IP) network, such as the Internet (Internet), a private IP network, or other data network.

Specifically, the terminal device needs to establish a connection with the access network device through a random access procedure, so as to implement data service through accessing the access network device.

It should be noted that the communication system shown in fig. 1 is only an example and is not limited to include one access network device and one terminal device shown in fig. 1. The communication system may also include a plurality of access network devices, a plurality of terminal devices, and other devices, which are not specifically listed herein.

Generally, access Control refers to that a terminal device determines when the terminal device can send a Random Access request according to indication information sent by a network device, where the indication information includes Physical Random Access Channel (PRACH) configuration parameters and/or Unified Access Control (UAC) configuration parameters.

In the access control in which the indication information includes the PRACH configuration parameters, as shown in fig. 2 to 3, the terminal device generates a random access response window after sending a random access request (MSG 1 or MSGA) to the network device, and when the random access response window expires and the terminal device does not receive a corresponding random access response (MSG 2 or MSGB), the terminal device resends the random access request (MSG 1 or MSGA). The number of retransmissions is determined by the maximum number of transmissions (preambleTransMax) in PRACH configuration parameters broadcasted by the System Information Broadcast (SIB). After the terminal equipment sends the wireless resource controllable connection request (MSG 3 or MSGA) to the network equipment, if the wireless resource control establishment (MSG 4 or MSGB) is not received or the competition resolving result of the wireless resource control establishment (MSG 4 or MSGB) is received is failure, the terminal equipment waits for a period of time and then sends the random access request (MSG 1 or MSGA). The waiting time is related to a backoff parameter value corresponding to a backoff parameter index (RAR backoff indicator) in the PRACH configuration parameters and a backoff time FACTOR (SCALING _ FACTOR _ BI).

The access control adopting the indication information including the UAC configuration parameters is used for judging whether the terminal equipment can initiate an access request. When the terminal device initiates an Access request, the Access request is associated with 1 Access Category (Access Category) and 1 or more Access IDs (Access Identity). The definition of the access category by the current 3GPP protocol is shown in table 1, and the definition of the access ID is shown in table 2.

TABLE 1 Access Categories

TABLE 2 Access ID

Specifically, the terminal device obtains the UAC configuration parameters broadcast by the network device. The UAC configuration parameters include a set of barring parameters. The blocking parameter set indicates a blocking factor (uac-BarringFactor) and a blocking time (uac-BarringTime) for each access category, and the value of a bit corresponding to each access ID indicates whether the access category is blocked or not. Wherein, generally, the UAC configuration parameters are defined as follows:

if the value of bit corresponding to the access ID in the barring parameter (uac-barring Access) is 0, the access request is allowed; otherwise, when the terminal equipment initiates an access request to the cell, a value is randomly selected from 0 to 1 to obtain a first random value, if the first random value is smaller than the blocking factor, the access request is allowed, otherwise, the terminal equipment is prohibited from initiating the access request. And if the terminal equipment is forbidden to initiate the access request, randomly taking a value from 0 to 1 to obtain a second random value, and starting a timer 390. And prohibiting the terminal equipment from accessing the cell before the timing of the timer timerT390 reaches the prohibition duration. Wherein the formula for calculating the prohibition duration includes:

t390= (700 +6 + randVal terminal device (0 to 1) × 100 acac-BarringTime) ms equation, where T390 is the prohibited duration, randVal terminal device (0 to 1) is the second random value, and uac-BarringTime is the barring time.

Although the network can perform different Access control on the RedCap terminal device and the non-RedCap terminal device through the method, and also perform different Access control on defined services (such as services corresponding to Access categories 0-10), some services are mainly uplink transmission, some services are mainly downlink transmission, and different Access control on the two types of services cannot be realized.

In summary, the services may be divided into services mainly based on uplink transmission and services mainly based on downlink transmission, and the access control method has a technical problem that different access controls cannot be performed on the two types of services.

Based on the foregoing technical problem, embodiments of the present invention provide a communication method, an apparatus, a readable storage medium, and a computer device.

Fig. 4 is a flowchart of a communication method according to an embodiment of the present invention, and as shown in fig. 4, the method includes:

step 101, obtaining indication information, where the indication information is used to indicate the number of sending times and/or sending opportunity of a random access request, and the random access request is used to establish a connection for a first service.

In the embodiment of the invention, each step is executed by the terminal equipment.

102, sending a random access request according to the indication information; the behavior is primary above the transmission of the first traffic or primary below the transmission of the first traffic.

In the embodiment of the present invention, the behavior of the first service above transmission mainly means that the uplink transmission ratio of the service exceeds a certain percentage. Wherein the percentage can be flexibly configured or preset. For example, set to 60%. For example, when the first service is mainly transmitted, the first service includes an industrial sensing service or a video monitoring service.

In the embodiment of the present invention, the following behavior of transmission of the first service mainly means that downlink transmission of the service accounts for a certain percentage. The downlink percentage can be flexibly configured or preset. For example, set to 60%. For example, when the transmission of the first service is mainly performed, the first service includes a download service or an online video viewing service.

In the embodiment of the present invention, an improvement is made for the above "access control using indication information including PRACH configuration parameters", and in order to implement different access controls for a service mainly based on uplink transmission and a service mainly based on downlink transmission, a new parameter is introduced for a first service in the PRACH configuration parameters, which specifically includes the following two alternatives:

a first alternative, as shown in fig. 5, sending a random access request for a first service according to indication information specifically includes:

step 201, determining the maximum sending times of the first service random access request according to the first service and the indication information.

As an alternative, the indication information includes a maximum number of transmissions of the first service. Step 201 specifically includes: and determining the maximum transmission times of the first service as the maximum sending times of the random access request of the first service. When the transmission of the first service is above the main behavior, determining the maximum transmission times (preambleTransMax _ UL) of the first service as the maximum sending times of the random access request of the first service; when the transmission of the first service is mainly as follows, the maximum number of transmissions of the first service (preambleTransMax _ DL) is determined as the maximum number of transmissions of the random access request of the first service.

In the embodiment of the present invention, when the transmission of the first service is mainly performed, the introduced new parameters of the PRACH configuration parameters include: a first traffic maximum transmission number factor (scaling _ factor _ Transmax _ UL); when the following actions are taken for the transmission of the first service, the introduced new parameters of the PRACH configuration parameters include: the first traffic maximum transmission times factor (scaling _ factor _ Transmax _ DL).

Step 202, when the random access response window is expired and the random access response sent by the base station is not received and the maximum sending times is not reached, retransmitting the random access request.

A second alternative, as shown in fig. 6, where the indication information is used to indicate a sending opportunity of the random access request, specifically includes:

and step 301, determining the waiting time according to the indication information.

In the embodiment of the invention, the indication information comprises a first service back-off time factor. Step 201 specifically includes: the product of the backoff parameter value and the first traffic backoff time factor is determined as the latency.

In the embodiment of the present invention, a terminal device receives random access response information (MSG 2 or MSGB) sent by a network device, where the random access response information includes a MAC sub pdu of a backoff factor (BI). The value corresponding to the MAC subPDU BI field is an index value in table 3, and the backoff parameter value is a backoff parameter value corresponding to the index value, as shown in table 3.

TABLE 3 rollback parameter values

Step 302, when the radio resource control setup message sent by the base station is not received or the contention resolution result of the received radio resource control setup message is failure, starting timing and sending a random access request to the base station when the timing reaches a waiting time.

In the embodiment of the present invention, an improvement is made on the above "access control using indication information including UAC configuration parameters", and specifically includes the following three alternatives:

in a first alternative, the access class number of the first service comprises one of 11-31. When the transmission of the first service is mainly performed, the access category number of the first service comprises one of 11-31; when the following actions are taken as main actions in the transmission of the first service, the access category number of the first service comprises one of 11-31; the access category number of the service mainly for uplink transmission is different from the access category number of the service mainly for downlink transmission.

In the embodiment of the invention, the indication information comprises a blocking parameter set; the barring parameter set comprises a barring factor and a barring time corresponding to the access class number of the first service.

step 401, determining the access category and the access ID of the random access request according to the first service.

Wherein each access category is used to indicate a barring factor and a barring time. If the value of bit (uac-holding for access) corresponding to the access ID is 0, it indicates that access is allowed. If the value of the bit corresponding to the access ID is 1, blocking judgment based on the access category is needed to be carried out.

And step 402, determining the value of the bit corresponding to the access ID in the blocking parameter set according to the access ID.

Further, in some embodiments, the terminal device may support multiple cards. For example, in the case that the terminal device is installed with the SIM card 1 and the SIM card 2, taking the case that the SIM card 1 is used for accessing the first network and the case that the SIM card 2 is used for accessing the second network as an example, when the terminal device is in a connected state in the first network, the terminal device may also need to listen to the paging message in the second network. If the terminal device monitors the paging message in the second network, if the terminal device does not respond to the paging message, the busy indication (busy indication) is fed back to the base station in the second network, so that the probability that the base station in the second network judges that the terminal device is not paged by mistake, the paging range is expanded, and the resource waste is reduced.

For example, the terminal device may feed back the busy indication to the base station in the second network through a NAS message (NAS message), for example, a service request (service request) message. For example, a field may be added to the NAS message to indicate a busy indication, which may increase the size of the NAS message, resulting in a larger standard workload and standard compatibility issues.

In view of this, embodiments of the present invention provide an information transmission method, which indicates that a terminal device is in a busy state through a service type, so that a field does not need to be newly added, and both standard workload and standard compatibility are less in problem, and are convenient to implement.

For example, as shown in fig. 13, a schematic flow chart of an information transmission method according to an embodiment of the present invention specifically includes the following steps:

1301. the terminal device notifies the network device of the first service type, wherein the first service type is a busy indication (busy indication) used for indicating that the terminal device is in a busy state.

The notifying, by the terminal device, the first service type to the network device may also be understood as: and the terminal equipment feeds back the first service type to the network equipment.

For example, the terminal device is in a busy state, which may refer to: the terminal device does not respond to the paging message sent by the network device, or the terminal device does not respond to the network access request from the network device, or the terminal device does not access the network, or the terminal device does not initiate the network access request to the network device, and the like.

For example, the terminal device receives a paging message sent by the network device, and notifies the network device of the first service type. Alternatively, the terminal device may notify the network device of the first service type in other cases, which is not limited to this.

1302. The network equipment receives the first service type notified by the terminal equipment and determines that the terminal equipment is in a busy state. Therefore, when the terminal equipment receives the paging message from the network equipment and does not respond to the paging message, the possibility that the network equipment misjudges that the terminal equipment does not receive the paging message and continues to page the terminal equipment is reduced, and resource waste is reduced.

In some embodiments, the terminal device may notify the network device of the first service type based on:

the terminal device sends a service request message (service request message) to the network device, wherein the service request message carries the first service type.

For example, the service request message may carry the first service type based on the following: the service request message includes: a first value indicating a first service type.

For example, as shown in table 4, the service request message includes the following fields or information elements (information elements): extended protocol descriptor, security header type, spark half time, service request message identity, ngKSI, service type, 5G-S-TMSI, uplink data status, PDU session status, allowed PDU status, and NAS message container. The first value is located in a field service type (service type) in the service request message.

TABLE 4

It should be noted that, for the related descriptions of extended protocol descriptor, security header type, spark half register, service request message identifier, ngKSI, 5G-S-TMSI, uplink data status, PDU session status, allowed PDU status, and NAS message container, reference may be made to the related descriptions in the communication protocol (e.g. 3gpp TS 24.501), and the details are not repeated herein. For example, see 3gpp TS 24.501 in section 9.2 for extended protocol descriptor.

Illustratively, the first value is a reserved bit value of a field service type in the service message. For example, the reserved bit value of the field service type includes 1100, 1101, 1110, 1111, and thus, the first value may be one of 1100, 1101, 1110, and 1111.

Taking the first value as 1100 as an example, the service type indicated by the bit value occupied by the field service type may be as shown in table 5-1 or table 5-2.

TABLE 5-1

Alternatively, the first and second electrodes may be,

TABLE 5-2

Taking the first value as 1101 as an example, the service type indicated by the bit value occupied by the field service type may be as shown in table 6-1 or table 6-2.

TABLE 6-1

Alternatively, the first and second electrodes may be,

TABLE 6-2

When the first value is 1110 or 1111, it is similar to when the first value is 1100 or 1111, and thus the description thereof is omitted.

It should be noted that, as in tables 2-1, 2-2, 3-1 and 3-2, the descriptions of the service message when the bit value of the field service type is 0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010 and 1011 can be referred to the relevant descriptions in the communication protocol (for example, section 9.11.3.50 in 3gpp TS 24.501), and will not be described herein again.

Of course, it is understood that, in the embodiment of the present invention, the first data may use other binary representations besides the binary representation, for example, decimal, 16, 8, and the like, which is not limited thereto.

The embodiment of the invention can be applied to a scene that the terminal equipment only supports a single SIM card, and of course, the embodiment of the invention can also be applied to a scene that the terminal equipment supports multiple SIM cards. The SIM card may be built in the terminal device, that is, an embedded SIM card (eSIM), or may be installed in the terminal device according to the user's own needs, which is not limited herein.

Take the terminal device with the first SIM card and the second SIM card as an example. For example, the first SIM card is used to access a first network, and the second SIM card is used to access a second network, where the first network and the second network may be networks belonging to the same operator or networks belonging to different operators. The first network device is located in a first network, and the second network device is located in a second network.

Note that, the first SIM card is taken as an example. The terminal device can access the first network through the first SIM card, but the terminal device can also access the first network without using the first SIM card according to the setting of the user, etc.

When the terminal device is in a connected state in the first network, the terminal device receives a paging message from the second network device, and the terminal device may notify the second network device of the first service type. For example, the terminal device may include a paging cause value in the paging message to indicate non-voice traffic. For another example, if the paging cause value included in the paging message is used to indicate a voice service, but the terminal device performs voice communication with the first network device, the second network device may also be notified of the first service type, so that the second network device may not continue to page the terminal device according to the first service type. Therefore, the possibility that the second network equipment expands the range to continue paging the terminal equipment is reduced, and the resource waste is reduced.

The above embodiments may be used alone or in combination with each other, and are not limited thereto.

In the embodiments provided by the present invention, the communication method provided by the embodiments of the present invention is described from the perspective of the terminal device and the network device as the execution subjects. In order to implement each function in the communication method provided by the embodiment of the present invention, the terminal device or the network device may include a hardware structure and/or a software module, and the functions are implemented in the form of a hardware structure, a software module, or a hardware structure and a software module. Whether any of the above-described functions is implemented as a hardware structure, a software module, or a hardware structure plus a software module depends upon the particular application and design constraints imposed on the technical solution.
