Description

Communication control method, unauthorized transmission method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a communication control method, an unauthorized transmission method, and an unauthorized transmission device.

Background

In the fourth generation mobile communication technology (4)^thGeneration, 4G) system, only one Numerology is supported, i.e., the length of Transmission Time Interval (TTI) and the subcarrier spacing are fixed. When air interface resources on a Radio Access Network (RAN) side are limited, congestion control is performed during random Access, and since a 4G system only supports one kind of Numerology, congestion control is performed only for one kind of Numerology.

But in the fifth generation mobile communication technology (5)^thGeneration, 5G) system supports Quality of Service (QoS) differentiated huge traffic types, such as Massive Machine Type Communication (mMTC) traffic, Ultra-Reliable and Low-Latency Communication (URLLC) traffic, Enhanced Mobile Broadband (eMB) traffic, Multimedia Broadcast Multicast Service (MBMS) to satisfy these differentiated servicesFor the requirement of transmission time interval and subcarrier interval schematic diagram adopted by different service types in the 5G mobile communication system shown in fig. 1, a New generation air interface technology (New Radio, NR) will support multiple numerologies simultaneously.

Long Term Evolution (LTE) systems have introduced many mechanisms to implement network admission control and congestion avoidance when congestion occurs, and these mechanisms are all performed based on a kind of Numerology, but do not consider how to perform random access congestion control under the kinds of Numerology, which is used for services in 5G systems.

The unauthorized transmission mode refers to that the access network equipment pre-allocates a part of resources in advance, and then when a plurality of terminal equipment need to transmit uplink data, the access network equipment does not need to be requested to allocate the resources, but directly contends the resources to transmit the data. Current unlicensed (Grant-Free) transmission also performs resource indication based on a Numerology, and does not consider how resource indication is performed under Numerology, which is a service that is performed by using several numerologies in a 5G system.

Detailed Description

Fig. 2 is a schematic diagram of a communication system according to an embodiment of the present invention. The system comprises a terminal device and a network device, wherein the network device comprises an access network device and a core network device (not shown). The terminal device of the embodiment of the present invention may communicate with one or more core networks through a Radio Access Network (RAN), and the terminal device may refer to an Access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. An access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, a UE in a future 5G network, etc.

The access network device in the embodiment of the present invention may be, for example, a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a Base Station (NodeB, NB) in a WCDMA system, an evolved Node B (eNB) or eNodeB) in an LTE system, or a relay Station, an access point, a vehicle-mounted device, a wearable device, a Wireless-Fidelity (Wi-Fi) site, a next-generation communication Base Station, such as a 5G Radio access network device (New Radio, NR, or "New generation air interface technology"), a Base Station or a small Station, or a micro Station.

Specifically, in fig. 2, taking a base station as an access network device as an example, the base station 102 may include multiple antenna groups. Each antenna group can include one or more antennas, e.g., one antenna group can include

antennas

104 and 106, another antenna group can include

antennas

108 and 110, and an additional group can include

antennas

112 and 114. 2 antennas are shown in fig. 2 for each antenna group, however, more or fewer antennas may be utilized for each group. Base station 102 can additionally include a transmitter chain and a receiver chain, each of which can be implemented as a number of components associated with signal transmission and reception, e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc., as will be appreciated by one skilled in the art.

Base station 102 may communicate with one or more terminal devices, such as terminal device 116 and terminal device 122. However, it is to be appreciated that base station 102 can communicate with any number of terminal devices similar to

terminal devices

116 or 122. As shown in fig. 2, terminal device 116 is in communication with

antennas

112 and 114, where

antennas

112 and 114 transmit information to terminal device 116 over forward link 118 and receive information from terminal device 116 over reverse link 120. In addition, terminal device 122 is in communication with

antennas

104 and 106, where

antennas

104 and 106 transmit information to terminal device 122 over forward link 124 and receive information from terminal device 122 over reverse link 126. In a Frequency Division Duplex (FDD) system, forward link 118 can utilize a different Frequency band than that used by reverse link 120, and forward link 124 can utilize a different Frequency band than that used by reverse link 126, for example. Further, in a Time Division Duplex (TDD) system, forward link 118 and reverse link 120 can utilize a common frequency band and forward link 124 and reverse link 126 can utilize a common frequency band.

Each group of antennas and/or the area in which they are designed to communicate is referred to as a sector of base station 102. For example, antenna groups can be designed to communicate to terminal devices in a sector of the areas covered by base station 102. During communication by base station 102 with

terminal devices

116 and 122 over forward links 118 and 124, respectively, the transmitting antennas of base station 102 can utilize beamforming to improve signal-to-noise ratio of forward links 118 and 124. Moreover, while base station 102 utilizes beamforming to transmit to

terminal devices

116 and 122 scattered randomly through an associated coverage, mobile devices in neighboring cells can be subject to less interference as compared to a base station transmitting through a single antenna to all its access terminal devices.

Base station 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting apparatus and/or a wireless communication receiving apparatus at a given time. When sending data, the wireless communication sending device may encode the data for transmission. Specifically, the wireless communication transmitting apparatus can acquire, for example, generate, receive from other communication apparatuses, or store in a memory, a certain number of data bits to be transmitted to the wireless communication receiving apparatus through the channel. Such data bits may be contained in a transport block or transport blocks of data, which may be segmented to produce multiple code blocks.

In this case, after obtaining data, a Media Access Control (MAC) layer knows to which Radio Link Control (RLC) layer corresponding to the logical channel the data is sent. The network slice refers to a customized logically complete network, which is mainly used for meeting different service requirements or tenant requirements, for example, the service requirements of URLLC and mtc are very different and may need different topologies and operation modes to be met, so that the network can generate two logically customized networks for the two services respectively, thereby meeting the corresponding requirements respectively. A terminal device may establish multiple radio data bearers/logical channels when served by a network slice.

Therefore, the bearer parameter correspondence notification message includes: a correspondence of an identity of the at least one logical channel to an identity of the set of logical channels, or a correspondence of an identity of the at least one data radio bearer to an identity of the set of data radio bearers, and/or a correspondence of an identity of the at least one network slice to an identity of the set of network slices. The RRC signaling includes: a state transition message, an RRC suspend request message, an RRC release message, etc.

It should be noted that this step is an optional step, and is indicated by a dotted line in the figure. As an alternative: the terminal device stores a correspondence of an identity of the at least one logical channel to an identity of the set of logical channels, or a correspondence of an identity of the at least one data radio bearer to an identity of the set of data radio bearers, and/or a correspondence of an identity of the at least one network slice to an identity of the set of network slices. This step may be performed after step S102, and the order of execution is not limited. By establishing a set of logical channels, a set of data radio bearers or a set of network slices, the signalling overhead of the access network device for sending radio access control messages for each logical channel, data radio bearer or network slice can be saved.

S102, the access network equipment sends a wireless access control message to the terminal equipment.

The access network device may broadcast the radio access control message to all terminal devices, or may send the radio access control message to corresponding terminal devices through RRC signaling. The RRC signaling includes: RRC release message, state transition message, attach request grant message, etc. And the terminal equipment receives the wireless access control message sent by the access network equipment. The message may be directed to access control of a terminal device in any state, where the state of the terminal device includes an idle state, a connected state, and a non-connected state, where for the connected terminal device, the terminal device may cause a Radio Link Failure (RLF) in the connected state due to a signal, and in this case, the terminal device also needs to re-access the network by using random access.

In this embodiment, the radio access control message includes: at least two Numerology random access control parameters, wherein the random access control parameters are used for congestion control when the terminal equipment is subjected to random access. The air interface resources of different numerologies correspond to different air interface parameters, such as subcarrier spacing, TTI, Cyclic Prefix (CP) length, and the like, or a combination of these parameters. The access network device includes more than two kinds of Numerology random access control parameters in the wireless access control message, and the terminal device can select one kind of Numerology random access control parameter to perform random access, so that the access network device optimizes the access strategies of all the terminal devices and ensures that the terminal devices can access as smoothly as possible.

Further, since the 5G system supports huge differentiation of service types, in order to meet the differentiation requirements, different terminal device types or services/bearers in the 5G mobile communication system use different transmission time intervals, subcarrier intervals, etc., so that different terminal device types or services/bearers need to be served with different Numerology to meet their QoS requirements. Accordingly, the radio access control message may include: at least two Numerology random access control parameters, wherein each Numerology random access control parameter comprises: a random access congestion control factor, wherein the random access congestion control factor corresponds to a terminal equipment type or a service/bearing parameter; the service/bearer parameters include: a traffic type of the terminal device, an identification of a logical channel (e.g. a logical channel ID), an identification of a set of logical channels, an identification of a data radio bearer (e.g. a data radio bearer ID), an identification of a set of data radio bearers, an identification of a network slice to which a traffic of the terminal device belongs (e.g. a network slice ID), or an identification of a set of network slices, the identifier of the network slice may be an identifier allocated by the core network for the terminal device, such as Network Slice Selection Assistance Information (NSSAI), or session management network slice selection assistance information (SM-NSSAI) slice/service type (slice/service type), or a slice differentiation number (SD), or a new identifier, or an identifier assigned by the access network to the terminal device. The access network equipment sends a random access control message to a specific terminal equipment or broadcasts the random access control message to all the intercepted terminal equipment, the random access control message can be used for a plurality of terminal equipment to select random access control parameters according to the terminal equipment types of the terminal equipment or a plurality of service/bearing parameters of the terminal equipment, and can also be used for a terminal equipment to select the random access control parameters according to one or a plurality of service/bearing parameters of the terminal equipment.

There are various ways to distinguish the service type of the terminal device, the first is to distinguish at the application layer (for example, QQ or hectogram), and the second is to distinguish through a logical channel or bearer (for example, bearer 1 data or bearer 2 data) if the user is in the Inactive state. The range of terminal types is relatively wide, for example, the terminal type may refer to a mobile phone user or a Vehicle-to-outside information exchange (V2X) user, or others.

The random access congestion control factor is a specific value (e.g. 0.4), and the terminal device generates a random number when performing random access, and performs random access if the random number is smaller than 0.4, and cannot perform random access if the random number is larger than 0.4. In the above-described mechanism 1 of the prior art, all the service types adopt the same random access congestion control factor, and in this embodiment, different random access congestion control factors may be set for different terminal device types or service/bearer parameters (for example, the random access congestion control factor of the URLLC service is 1, the random access congestion control factor of the mtc service is 0.4, and it is obvious that the URLLC service has a higher priority), so that the purpose of performing different random access congestion control for different services/bearers can be achieved.

Optionally, before step S102, the following steps may be further included: the access network device determines random access control parameters for the at least two numerologies.

In this embodiment, the random access control parameters of Numerology may be represented in the form of a structure. Each Numerology has a corresponding Random Access Channel (RACH) resource, and the RACH resource includes: the structural body parameter of the Numerology is used as a selection basis for the air interface parameter corresponding to the Numerology.

As an implementation manner, each of the radio access control messages may include a Numerology random access control parameter that needs congestion control, that is, multiple Numerology random access control parameters are sent through multiple radio access control messages or multiple Information Elements (IEs) in one radio access control message. Taking the random access congestion control according to the service type (service) as an example, an example of the congestion control structure (one) shown below is as follows:

example of congestion control structure (one):

in the structure, BarringPerNumerality-Category-r 15 represents a Numerality random access control parameter; Numerology-Category-r15 is a newly added parameter (compared to the Numerology structure of mechanism 1 in the prior art), and the value is an integer between [1, maxnnumerology-Cat-r 15], where maxnnumerology-Cat-r 15 refers to a maximum value of the number of numerologies supported by the system, and therefore, a terminal device selects a specific value of Numerology-Category-r15, which means that the terminal device performs random access according to which random access control parameter corresponding to Numerology, and if access is successful, acquires an air interface resource corresponding to the Numerology for data transmission; Numerology-BarringConfig-r15 refers to a Numerology random access control parameter; As-Service-List represents the Service type List; the ac-service-BarringConfig-r15 refers to a random access control parameter corresponding to a service type, and the random access control parameter includes: ac-BarringFactor-r13, i.e., a random access congestion control factor; the ac-BarringTime represents the delay time after random access, before the random access, the terminal equipment generates a random number between [0 and 1], and if the random number is lower than the ac-BarringFactor sent by the network equipment of the access network, the access attempt is considered to be successful; otherwise, the terminal considers that the access attempt fails, it will generate a random number between [0, 1], start timer Tbarring ("Tbarring" ═ 0.7+0.6 arand) × ac-BarringTime), and will not try to access the network again within this time; Numerology-Load, Numerology Load, according to the difference of Load, the terminal device uses different Numerology, so that the congestion control is more refined, a group of values {100, p05, … p95} on the right side of the parameter is selectable Load value, the access network device selects the corresponding current Load value in the group of values according to the current Load, it should be noted that the Load information may be included in the radio access control message, or may be sent to the terminal device through a separate message.

As another implementation manner, each radio access control message may also include only one random access control parameter corresponding to one service/bearer parameter in Numerology, and the following example of the structure (two) is shown:

example of Congestion control Structure (II)

In the structure, barringPernumerology-Category-r15 indicates only one kind of Numerology, barringPerService-Category-r15 indicates only one kind of Service-corresponding random access control parameter, and other parameters have the same meaning as the structure.

As yet another implementation, the radio access control message may also be a list comprising Numerology including correspondence of the random access congestion control factors of the at least two numerologies with the terminal device type or traffic/bearer parameters. Taking the random access congestion control according to the service type as an example, the following example of the congestion control structure (iii) is shown:

example of Congestion control Structure (III)

In this structure, BarringPerNumeriology-List is a List of integer values from 1 to maxNumeriology, meaning a Numerology List, and As-Service-List, meaning that its traffic type is also a List. The other parameters have the same meanings as those of the above-mentioned structure.

While in the structure illustrated below, Numerology is a list and all Numerology is congestion controlled for one traffic type. An example of the congestion control structure (iv) shown below:

example of Congestion control Structure (IV)

As another implementation manner, the plurality of numerologies included in the radio access control message may also be a bitmap, the bitmap of Numerology is used to indicate whether the plurality of numerologies need congestion control, and of course, the radio access control message further includes a random access control parameter of the Numerology that needs congestion control. An example of the congestion control structure (v) shown below:

example of Congestion control Structure (V)

In the structure, the value of As-barringforspecial Numerology is a BIT STRING (BIT STRING), for example, the message includes 5 numerologies in total, 1 indicates that the Numerology needs congestion control, 0 indicates that the Numerology does not need congestion control, 11001 indicates that 1 st, 2 nd, 5 th numerologies need congestion control, 3 rd, 4 th numerologies do not need congestion control, and if a terminal device employs the 3 rd, 4 th Numerology, congestion control is not needed for the terminal device or the traffic/bearer of the terminal device. For example, for a service with extremely low delay, Numerology adopted by the service may need to perform congestion control, otherwise, RACH resources of the service are seized, and self delay cannot be satisfied; the MTC traffic is not sensitive to delay and may not be congestion controlled.

As another implementation manner, the type of the terminal device or the traffic/bearer parameter that needs to perform congestion control may also be a bitmap, which is an example of a congestion control structure (six) as shown below:

example of Congestion control Structure (VI)

In the structure, BarringPerNumerology-List represents a Numerology List, and the value of As-BarringForSpecialService is a BIT STRING (BIT STRING), and whether congestion control is required for each type of traffic in Numerology is represented in the form of a bitmap. For example, a terminal device has 5 service types, and for these 5 service types, a 5-bit bitmap is generated, where 1 indicates that the service type is restricted from access, and 0 indicates that the service type is not restricted from access, if the bitmap is 00110, the service types 1, 2, and 5 are not affected by the access control policy, and the service types 3 and 4 are affected by the access control policy; its bitmap may also be such that: the corresponding number 0 indicates that the service type is restricted from access, the number 1 indicates that access is not restricted, and then if the bitmap is 11001, the service types 1, 2, 5 are not affected by the access control policy, and the service types 3, 4 are affected by the access control policy. The other parameters of the structure have the same meanings as those of the structure.

Further, all terminal device types or service/bearer parameters corresponding to a Numerology correspond to a random access congestion control factor; or each terminal device type or traffic/bearer parameter corresponding to a Numerology corresponds to a random access congestion control factor. The correspondence is applicable to any of the above structures.

For example, an example of the congestion control configuration body (seven) shown below:

example of Congestion control Structure (VII)

In the structure, the value of As-BarringForSpecialservice is a BIT STRING (BIT STRING), and whether congestion control is required for each type of traffic in Numerology is represented in the form of a bitmap. However, all services use a radio access control parameter, and only whether to use a bitmap according to the Service is determined.

S103, the terminal equipment selects a random access control parameter of Numerology from the at least two numerologies.

After receiving multiple kinds of Numerology random access control parameters, the terminal equipment selects one kind of Numerology random access control parameters. Before random access, the terminal equipment generates a random number between [0, 1], and if the random number is lower than a random access congestion control factor in a random access control parameter, the access attempt is considered to be successful; otherwise, the terminal considers that the access attempt is failed, it will generate a random number between [0, 1], start timer Tbarring (0.7+0.6 + rand) ac-BarringTime), during which time it will not try to access the network again, and select a random access control parameter after the timer time is reached.

Further, the terminal device obtains a random access control parameter corresponding to the terminal device type or the service/bearer parameter according to the terminal device type or the service/bearer parameter and according to the received multiple Numerology random access control parameters.

And S104, the terminal equipment sends a random access request to the access network equipment according to the selected random access control parameter of Numerology.

Specifically, as described above, when performing random access, the terminal device generates a random number, performs random access if the random number is smaller than the selected random access congestion control factor, and cannot perform random access if the random number is larger than the selected random access congestion control factor. And when the random access is carried out, the selected RACH resource of the Numerology is adopted for carrying out the random access. And the access network equipment receives a random access request sent by the terminal equipment according to the random access control parameter of one of the at least two kinds of Numerology, and performs random access.

The beneficial effects of using the scheme of this embodiment are illustrated below: numerology of a short TTI (e.g., 0.1ms) is generally used to serve URLLC traffic, i.e., very low latency traffic, but if the same congestion control scheme is adopted for URLLC and large connection traffic (MTC) on the Numerology, URLLC users will be subjected to MTC traffic at the time of random access, and due to the large number of MTC users, the Numerology will be preempted, so that the URLLC cannot successfully access the network (collision), and thus cannot meet QoS requirements. However, if we use different congestion control for different services on the Numerology, that is, the access network device notifies the terminal device of Numerology that can be used according to different service types, and other service types, for example, mtc, use other Numerology, that is, TTI of 0.1ms will not be selected, then it can be ensured that URLLC service can be smoothly accessed to the network.

According to the wireless access congestion control method provided by the embodiment of the invention, the access network equipment provides a plurality of selectable Numeriology random access control parameters for the terminal equipment to select, so that the terminal equipment can select different Numeriology for service, and the access network equipment optimizes a random access congestion control strategy; and the terminal equipment can select a corresponding random access control parameter of Numerology according to the type of the terminal equipment or the service/bearer parameter of the terminal equipment, and the terminal equipment can perform refined congestion control aiming at different services/bearers.

Similar to the radio access congestion control, different numologies may have different unlicensed transmission resources, and for different services/bearers, it is necessary to transmit data according to different unlicensed transmission resource configuration indications on the Numerology, for which the following description is specifically applied:

referring to fig. 8, fig. 8 is an interaction diagram of an unauthorized transmission method according to an embodiment of the present invention. The method comprises the following steps:

s201, the access network equipment sends a notification message of the corresponding relation of the bearer parameters to the terminal equipment through a Radio Resource Control (RRC) signaling.

For the terminal device in the non-connected state, since it also retains the data plane logical channel information, or the data radio bearer information, or the information of which network slice each service belongs to, in order to save the signaling overhead of the access network device for sending the unlicensed transmission resource configuration message or the unlicensed transmission resource configuration parameter for each logical channel, data radio bearer, or network slice, in this embodiment, the unlicensed transmission resource configuration needs to be performed for each logical channel set, each data radio bearer set, or network slice set. The logical channel means that the access network device establishes different bearers for the terminal device, and each bearer corresponds to one logical channel, so that after the medium access control layer obtains data, the medium access control layer knows to which logical channel the data is sent to the radio link layer control protocol layer corresponding to the logical channel. The network slice refers to a customized logically complete network, which is mainly used for meeting different service requirements or tenant requirements, for example, the service requirements of URLLC and mtc are very different and may need different topologies and operation modes to be met, so that the network can generate two logically customized networks for the two services respectively, thereby meeting the corresponding requirements respectively. A terminal device may establish multiple radio data bearers/logical channels when served by a network slice.

The bearer parameter correspondence notification message includes: a correspondence of an identity of the at least one logical channel to an identity of the set of logical channels, or a correspondence of an identity of the at least one data radio bearer to an identity of the set of data radio bearers, and/or a correspondence of an identity of the at least one network slice to an identity of the set of network slices.

The RRC signaling includes: a state transition message, an RRC suspend request message, an RRC release message, etc.

It should be noted that this step is an optional step, and is indicated by a dotted line in the figure. As an alternative: the terminal device stores a correspondence of an identity of the at least one logical channel to an identity of the set of logical channels, or a correspondence of an identity of the at least one data radio bearer to an identity of the set of data radio bearers, and/or a correspondence of an identity of the at least one network slice to an identity of the set of network slices. This step may be performed after step S202, and the order of execution is not limited. By establishing a logical channel set, a data radio bearer set or a network slice set, the signaling overhead of the access network device for sending the unauthorized transmission resource configuration message for each logical channel, data radio bearer or network slice can be saved.

S202, the access network equipment sends an unauthorized transmission resource configuration message to the terminal equipment.

The traditional data transmission mode is as follows: the terminal equipment needs to transmit uplink data, then firstly, the access network equipment needs to request resources, after receiving the request, the access network equipment allocates the resources for the terminal equipment, and then, the access network equipment informs the terminal equipment, so that the terminal equipment can transmit the uplink data on the corresponding resources. The unauthorized transmission mode of this embodiment refers to that the access network device pre-allocates a part of resources in advance, and then when a plurality of terminal devices need to transmit uplink data, the access network device does not need to request to allocate resources, but directly contends for the resources to transmit data. In this embodiment, the access network device sends the unauthorized transmission resource configuration message to the terminal device, and the terminal device obtains the unauthorized transmission resource according to the unauthorized transmission resource configuration message.

The access network device may broadcast the radio access control message to all terminal devices, or may send the radio access control message to corresponding terminal devices through RRC signaling. The RRC signaling includes: RRC release message, state transition message, attach request grant message, etc. And the terminal equipment receives the unauthorized transmission resource configuration message sent by the access network equipment. The terminal device is typically a non-connected terminal device.

In this embodiment, the unauthorized transmission resource configuration message includes: at least two Numerology unlicensed transmission resources configuration parameters comprising unlicensed transmission resources and/or a configuration indication of the unlicensed transmission resources. The air interface resources of different numerologies correspond to different air interface parameters, such as subcarrier spacing, transmission time interval, cyclic prefix length, and the like, or a combination of these parameters. The access network device includes more than two kinds of unlicensed transmission resource configuration parameters of Numerology in the unlicensed transmission resource configuration message, the terminal device can select one kind of unlicensed transmission resource configuration parameters of Numerology for data transmission, and the access network device optimizes the unlicensed transmission resource configuration policies of all the terminal devices.

Further, since the 5G system supports huge differentiated service types, in order to meet the differentiated requirements, the unlicensed transmission is performed in the 5G mobile communication system, different terminal device types and/or services/bearers employ different transmission time intervals, subcarrier intervals, and the like, and therefore, different terminal device types and/or services/bearers may employ different Numerology to serve their QoS requirements. Therefore, the configuration indication of the unlicensed transmission resource corresponds to a terminal device type or a service/bearer parameter, where the service/bearer parameter includes: the service type of the terminal device, an identifier of a logical channel (e.g., a logical channel ID), an identifier of a logical channel set, an identifier of a data radio bearer (e.g., a data radio bearer ID), an identifier of a data radio bearer set, an identifier of a network slice to which a service of the terminal device belongs, or an identifier of a network slice set, where the identifier of the network slice may be an identifier allocated by a core network to the terminal device, such as Network Slice Selection Assistance Information (NSSAI), or session management network slice selection assistance information (session management-network slice selection assistance information, SM-NSSAI) slice/service type (slice/service type), or slice partition number (SD), or a new identifier, or may also be an identifier allocated by an access network to the terminal device. The access network equipment sends an unauthorized transmission resource configuration message to a specific terminal equipment or broadcasts the unauthorized transmission resource configuration message to all the intercepted terminal equipment, and the unauthorized transmission resource configuration message can be used for selecting the resource configuration of unauthorized transmission of a plurality of terminal equipment according to the terminal equipment types of the plurality of terminal equipment or a plurality of service/bearing parameters of the plurality of terminal equipment, and can also be used for selecting the resource configuration of unauthorized transmission of one terminal equipment according to one or a plurality of service/bearing parameters of the terminal equipment.

It should be noted that the unlicensed transmission resources may be already notified to the terminal device, and therefore, the unlicensed transmission resource configuration parameter may include only a configuration indication of the unlicensed transmission resources.

There are various ways to distinguish the service types, the first is to distinguish at the application layer (for example, QQ or hectogram), and the second is to distinguish through the logical channel or bearer (for example, bearer 1 data or bearer 2 data) if the user is in the Inactive state. The range of terminal device types is relatively broad, for example the terminal device type may refer to a cell phone user or a V2X user, or others.

Optionally, before step S202, the following steps may be further included: the access network device determines at least two Numerology unlicensed transmission resource configuration parameters.

In this embodiment, the unlicensed transmission configuration parameters of Numerology may be represented in the form of a structure. Each Numerology has corresponding unlicensed transmission resources, which include: the structural body parameter of the Numerology is used as a selection basis for the air interface parameter corresponding to the Numerology.

As an implementation manner, each of the unlicensed transmission resource configuration messages may include one kind of unlicensed transmission configuration parameters of Numerology, that is, multiple kinds of unlicensed transmission configuration parameters of Numerology are sent through multiple unlicensed transmission resource configuration messages or multiple Information Elements (IEs) in one piece of unlicensed transmission resource configuration Information. Taking an example of performing unauthorized transmission resource configuration according to a service type (service), an example (a) of an unauthorized transmission resource configuration structure is shown as follows:

example of an unlicensed transmission resource configuration Structure (I)

In the structure, GFPerNumeriology-Category-r 15 represents an unauthorized transmission configuration parameter of Numeriology; Numerology-Category-r15 is a newly added parameter (compared to the Numerology structure of mechanism 1 in the prior art), and the value is an integer between [1, maxnnumerology-Cat-r 15], where maxnnumerology-Cat-r 15 refers to the maximum value of the number of numerologies supported by the system, and therefore, a terminal device selects a specific value of Numerology-Category-r15, which indicates that the terminal device performs unauthorized transmission according to which unauthorized transmission configuration parameter corresponding to Numerology, and acquires an air interface resource corresponding to the Numerology for data transmission if the configuration is successful; Numerology-GFConfig-r15 refers to a Numerology unlicensed transmission configuration parameter; As-Service-List represents the Service type List; the ac-service-GFConfig-r15 refers to an unauthorized transmission configuration parameter corresponding to the service type, and the unauthorized transmission configuration parameter includes: ac-GFFactor-r13, i.e., an unlicensed transmission resource allocation factor; ac-GFTime, which means that if the first GF transmission is not successful, the timer TGF is started up (0.7+0.6 × rand) until the next GF transmission needs waiting time, and no GF is tried again in the time when the transmission fails; numeral-Load, Load of numeral, according to different loads, terminal device uses different numeral, so as to make configuration of unlicensed transmission resources more refined, a set of values {100, p05, … p95} on the right side of the parameter is selectable Load values, access network device selects corresponding current Load values in the set of values according to current Load, it should be noted that the Load information may be included in the configuration message of unlicensed transmission resources, or may be sent to terminal device through a separate message.

As another implementation manner, each unlicensed transmission resource configuration message may also include only one unlicensed transmission configuration parameter corresponding to one service/bearer parameter in Numerology, such as the following example (two) of the unlicensed transmission resource configuration structure:

example of unlicensed transmission resource configuration Structure (II)

In the structure, GFPerNumerology-Category-r15 indicates only one Numerology, gfservice-Category-r 15 indicates only one Service-corresponding unlicensed transmission configuration parameter, and other parameters have the same meaning as the structure.

As still another implementation manner, the unlicensed transmission resource configuration message may also be a list including Numerology, where the list of Numerology includes a correspondence relationship between the unlicensed transmission resource configuration factors of the at least two kinds of Numerology and the terminal device type or traffic/bearer parameter. Taking the configuration of the unlicensed transmission resource according to the service type as an example, an example (three) of the structure of the unlicensed transmission resource configuration is shown as follows:

example (III) of unlicensed transmission resource configuration Structure

In this structure, GFPernumerology-List is a List of integer values from 1 to maxNumeriology, meaning a Numerology List, and As-Service-List, meaning that its business type is also a List. The other parameters have the same meanings as those of the above-mentioned structure.

While in the structure illustrated below, Numerology is a list and all Numerology is for unlicensed transmission resources configuration for one traffic type. An example of the unlicensed transmission resource configuration structure (four) shown below:

example of unlicensed transmission resource configuration Structure (IV)

As another implementation manner, the plurality of numerologies included in the unlicensed transmission resource configuration message may also be a bitmap, where the bitmap of Numerology is used to indicate whether the plurality of numerologies need to perform unlicensed transmission resource configuration, and of course, the unlicensed transmission resource configuration message further includes unlicensed transmission configuration parameters of the Numerology that needs to perform unlicensed transmission. An example of an unlicensed transmission resource configuration structure (v) shown below:

example of unlicensed transmission resource configuration Structure (V)

In the structure, the value of As-GFForSpecialNumerology is a BIT STRING (BIT STRING), for example, the message includes 5 numerologies in total, 1 indicates that the Numerology requires unlicensed transmission resource configuration, 0 indicates that the Numerology does not require unlicensed transmission resource configuration, 11001 indicates that 1, 2, 5 numerologies require unlicensed transmission resource configuration, 3, 4 numerologies do not require unlicensed transmission resource configuration, and if the terminal device employs 3, 4 numerologies, the terminal device or the traffic/bearer of the terminal device does not require unlicensed transmission resource configuration. For example, for a service with extremely low latency, the Numerology adopted by the service may need to perform unauthorized transmission resource configuration, otherwise, the unauthorized transmission resource is preempted, and the latency of the service cannot meet the requirement; the MTC service is not sensitive to time delay, and may not be configured with unauthorized transmission resources.

As another implementation manner, the type of the terminal device or the service/bearer parameter that needs to perform the configuration of the unlicensed transmission resource may also be a bitmap, as shown in the following example (six) of the structure of the configuration of the unlicensed transmission resource:

example (six) of unlicensed transmission resource configuration Structure

In the structure, GFPerNumerology-List represents a Numerology List, and the value of As-GFForSpecialService is a BIT STRING (BIT STRING), and whether the service type in each Numerology needs the configuration of the unlicensed transmission resource is represented in the form of a bitmap. For example, a terminal device has 5 service types, and 5bit bitmaps are generated for the 5 service types, where 1 indicates that the service type needs to be subjected to unauthorized transmission resource configuration, and 0 indicates that the unauthorized transmission resource configuration is not needed, if the bitmap is 00110, the service types 1, 2, and 5 are not affected by an unauthorized transmission resource configuration policy, and the service types 3 and 4 are affected by an unauthorized transmission resource configuration policy; its bitmap may also be such that: the corresponding number 0 indicates that the service type needs to be configured with an unauthorized transmission resource, the number 1 indicates that the unauthorized transmission resource is not needed to be configured, and if the bitmap is 11001, the service types 1, 2 and 5 are not affected by the unauthorized transmission resource configuration policy, and the service types 3 and 4 are affected by the unauthorized transmission resource configuration policy. The other parameters of the structure have the same meanings as those of the structure.

Further, all terminal device types or traffic/bearer parameters corresponding to a Numerology correspond to an unlicensed transmission resource configuration indication; or each terminal equipment type or service/bearer parameter corresponding to a Numerology corresponds to an unlicensed transmission resource configuration indication. The correspondence is applicable to any of the above structures.

For example, an example (seven) of the unlicensed transmission resource configuration structure is shown below:

in the structure, the value of As-GFForspecialized service is a BIT STRING (BIT STRING), and whether unauthorized transmission resource allocation is required for each service type in Numerology is represented in the form of a bitmap. However, all services use an unlicensed transmission resource configuration parameter, and only whether to use a bitmap according to the Service is determined.
