Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0037] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0038] First, some nouns or terms that appear in the description of the embodiments of the present application are subject to the following explanations:

[0039] NB-IoT: Narrowband Internet of Things.

[0040] QoS: Quality of Service.

[0041] PCO: Protocol Configuration Option, protocol configuration option.

[0042] According to an embodiment of the present invention, an embodiment of a parameter transmission method based on narrowband Internet of Things is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0043] Figure 1 The process of a parameter transmission method based on narrowband Internet of Things according to an embodiment of the present invention is as follows Figure 1 ,like Figure 1 As shown, the method comprises the following steps:

[0044] Step S102: The first device obtains an Evolved Packet System service quality parameter, wherein the first device and the second device perform data transmission based on the narrowband Internet of Things, and the Evolved Packet System service quality parameter carries an uplink and downlink maximum bit rate, but does not carry an uplink and downlink guaranteed bit rate;

[0045] Step S104: Send an Evolved Packet System Quality of Service parameter to the second device.

[0046] In the above embodiment of the present application, the first device obtains the service quality parameters of the evolved packet system, wherein the first device and the second device perform data transmission based on the narrowband Internet of Things, and the service quality parameters of the evolved packet system carry the maximum uplink and downlink bit rates, and do not carry the uplink and downlink guaranteed bit rates; the service quality parameters of the evolved packet system are sent to the second device, thereby achieving the purpose of reducing the constraint relationship between different parameters, and when the uplink and downlink maximum bit rate MBR is carried in the service quality QoS parameters, the uplink and downlink guaranteed bit rate GBR may not be carried, thereby achieving the technical effect of streamlining the Internet of Things air interface parameters, and further solving the technical problem of redundant air interface parameters of the Internet of Things based on the narrowband Internet of Things.

[0047] It should be noted that the maximum uplink rate supported by NB-IoT is 200kbps, and the maximum downlink rate is 250kbps; NB-IoT does not support GBR; NB-IoT does not support VoLTE, so it does not support QCI5, and the supported QCI is generally QCI6 / 7 / 8 / 9; 2) NB-IoT supports the configuration of IPv4 / IPv6 addresses, MTU and other parameters through PCO parameters, but does not support the configuration of IMS, QoS rules, QoSflow descriptions and other parameters.

[0048] In the above step S102, the first device and the second device may be a user side device and a network side device, respectively, wherein, when the first device is a user side device (such as a user device), the second device may be a network side device (such as a device in a narrowband Internet of Things); when the first device is a network side device (such as a device in a narrowband Internet of Things), the second device may be a user side device (such as a user device).

[0049] In the above step S102, the evolved packet system service quality parameters are EPS QoS parameters, which refer to a series of parameters used to describe and control the network service quality in the evolved packet system EPS network. These parameters define how the network provides different qualities of service for different services, ensuring that users can obtain the expected service level when using the network.

[0050] Figure 2 is a schematic diagram of a message format of an initial Evolved Packet System Quality of Service parameter EPS QoS according to an embodiment of the present invention, such as Figure 2As shown in the figure, the detailed format of the evolved packet system service quality parameter includes: the first byte represents: information element identifier for identifying and controlling service quality (EPS quality of service IEI); the second byte represents: length of EPS quality of service contents; the third byte represents: quality of service class identifier (QCI); the fourth byte represents: maximum uplink bit rate; the fifth byte represents: maximum downlink bit rate; the sixth byte represents: guaranteed uplink bit rate; the seventh byte represents: guaranteed downlink bit rate; the eighth byte represents: maximum uplink bit rate for the first extension; the ninth byte represents: maximum downlink bit rate for the first extension; the eighth byte represents: maximum uplink bit rate for the first extension; the ninth byte represents: maximum downlink bit rate for the first extension. The tenth byte indicates: the first extended uplink guaranteed bit rate (Guaranteed bit rate for uplink(extended)); the eleventh byte indicates: the first extended downlink guaranteed bit rate (Guaranteed bit rate for downlink(extended)) The twelfth byte indicates: the second extended uplink maximum bit rate (Maximum bit rate for uplink(extended-2)); the thirteenth byte indicates: the second extended downlink maximum bit rate (Maximum bit rate for downlink(extended-2)); the fourteenth byte indicates: the second extended uplink guaranteed bit rate (Guaranteed bit ratefor uplink(extended-2)); the fifteenth byte indicates: the second extended downlink guaranteed bit rate (Guaranteed bit rate for downlink(extended-2)).

[0051] Optionally, for Figure 2 The detailed format of the Evolved Packet System Quality of Service parameters shown is defined as follows:

[0052] Rule 1: If the uplink MBR is carried, the downlink MBR, uplink GBR, and downlink GBR must be carried.

[0053] Optionally, if byte 4 is included, bytes 5-7 must also be included, and bytes 8-15 may be included optionally. If byte 8 is included, bytes 4-11 must also be included, and bytes 12-15 may be included optionally. If byte 12 is included, bytes 4-15 must also be included. The length of the EPS QoS Information Element (IE) can be 3 bytes, 7 bytes, 11 bytes, or 15 bytes.

[0054] That is, bytes 4 to 7 form a group, bytes 8 to 11 form a group, and bytes 12 to 15 form a group, and each group of parameters must be carried at the same time.

[0055] Regulation 2: The rate range represented by the upstream MBR and downstream MBR parameters is 1-8640 kbps.

[0056] Optionally, the specific content of Regulation 2 is:

[0057] “Maximum bit rate for uplink,octet 4

[0058] Bits 8 7 6 5 4 3 2 1

[0060] In UE to network direction:

[0061] 0 0 0 0 0 0 0 0 Subscribed maximum bit rate for uplink

[0062] In network to UE direction:

[0063] 0 0 0 0 0 0 0 0 Reserved

[0064] In UE to network direction and in network to UE direction:

[0065] 0 0 0 0 0 0 0 1 The maximum bit rate is binary coded in 8bits,using agranularity of1kbps

[0066] to give a range of values ​​from 1kbps to 63kbps in 1kbps increments. 0 0 1 1 1 1 1 1

[0068] 0 1 0 0 0 0 0 0 The maximumbit rate is 64kbps+((the binary codedvalue in 8bits–01000000)*8kbps)

[0069] to give a range of values ​​from 64kbps to 568kbps in 8kbpsincrements. 0 1 1 1 1 1 1 1

[0071] 1 0 0 0 0 0 0 0 The maximum bit rate is 576kbps+((the binary codedvalue in 8bits–10000000)*64kbps)

[0072] to give a range of values ​​from 576kbps to 8640kbps in 64kbpsincrements. 1 1 1 1 1 1 1 0

[0074] 1 1 1 1 1 1 1 1 0kbps

[0075] Maximum bit rate for downlink,octet 5

[0076] Coding is identical to that of maximum bit rate for uplink".

[0077] Optionally, the fourth byte of the evolved packet system quality of service parameter in the above rule 2 represents the maximum uplink bit rate, specifically:

[0078] In the User Equipment (UE) to network direction, this byte is used to indicate the subscribed maximum uplink bit rate.

[0079] When all bits of this byte are 0 (i.e. 00000000), it indicates that there is a specific maximum bit rate setting in the UE-to-network direction, but this setting is not directly represented by this byte.

[0080] In the direction from network to UE, this byte is also reserved for specific purposes, but when its value is 00000001, it indicates that the following encoding method will be used to indicate the maximum bit rate.

[0081] Optionally, the maximum bit rate encoding method is:

[0082] For rates from 1kbps to 63kbps:

[0083] When the byte value is between 00000000 and 01111111, the maximum bit rate is calculated by multiplying the byte value (in binary) by 1kbps, and ranges from 1kbps to 63kbps.

[0084] For rates from 64kbps to 568kbps:

[0085] When the byte value is greater than 01111111 but less than 10000000 (i.e. starting from 10000000), the maximum bit rate is calculated by adding ((byte value - 01000000) * 8kbps) to 64kbps, ranging from 64kbps to 568kbps, increasing by 8kbps each time.

[0086] For rates from 576kbps to 8640kbps:

[0087] When the highest bit of the byte is 1 (i.e. from 10000000 to 11111111), the maximum bit rate is calculated by adding ((byte value - 10000000) * 64kbps) to 576kbps, ranging from 576kbps to 8640kbps, increasing by 64kbps each time.

[0088] Optionally, the 5th byte of the evolved packet system service quality parameter in the above rule 2 represents the maximum downlink bit rate. The maximum downlink bit rate is represented by the 5th byte, and the encoding method of the downlink maximum bit rate is exactly the same as that of the uplink.

[0089] Figure 3 is a schematic diagram of a message format of an optimized evolved packet system quality of service parameter EPS QoS according to an embodiment of the present invention, such as Figure 3As shown, the detailed format of the evolved packet system service quality parameters includes: the first byte represents: information element identifier for identifying and controlling service quality (EPS quality of service IEI); the second byte represents: length of evolved packet system service quality content (Length of EPS quality of service contents); the third byte represents: quality of service class identifier (Quality of Service Class Identifier, QCI); the fourth byte represents: maximum uplink bit rate (Maximum bit rate for uplink); the fifth byte represents: maximum downlink bit rate (Maximum bit rate for downlink).

[0090] Optionally, for Figure 3 The detailed format of the Evolved Packet System Quality of Service parameters shown in the figure has the following provisions3:

[0091] “Bits 8 7 6 5 4 3 2 1

[0093] In UE to network direction:

[0094] 0 0 0 0 0 0 0 0 Subscribed maximum bit rate for uplink

[0095] In network to UE direction:

[0096] 0 0 0 0 0 0 0 0 Reserved

[0097] In UE to network direction and in network to UE direction:

[0098] 0 0 0 0 0 0 0 1 The maximum bit rate is binary coded in 8bits,using agranularity of1kbps

[0099] to give a range of values ​​from1kbps to 254kbps in 1kbps increments. 1 1 1 1 1 1 1 0

[0101] 1 1 1 1 1 1 1 1 0kbps".

[0102] Optionally, the above rule 3 is as follows:

[0103] "In the UE to network direction: 8 bits (Bits 8 7 6 5 4 3 2 1) are all set to 0, indicating the subscribed maximum uplink bit rate.

[0104] In the network to UE direction: all 8 bits are set to 0, but this part is reserved.

[0105] Special settings in the UE-to-network and network-to-UE directions: When the bit is set to 00000001, it has a specific meaning.

[0106] Maximum bit rate encoding method: The maximum bit rate is represented by 8-bit binary code.

[0107] Maximum bitrate granularity: The encoding granularity is 1kbps.

[0108] The maximum bitrate range: This means that the encoded value can be increased from 1kbps to 254kbps in 1kbps increments.

[0109] Special value for maximum bitrate: All 1s (11111111) or 255kbps is not used directly in the description, but usually such encoding may be used to indicate special states, such as 'unlimited' or 'invalid value'. All 0s (00000000) are used here to indicate the starting value of the subscribed maximum bitrate or some kind of default / reserved state".

[0110] As an optional embodiment, the maximum uplink and downlink bit rates are represented by 8-bit binary code, 1 kbps to 254 kbps, and the coding granularity is one thousand bits per second.

[0111] In the above embodiment of the present application, the maximum uplink rate supported by NB-IoT is 200kbps, and the maximum downlink rate is 250kbps. 8-bit binary code can represent 256 numbers. Therefore, the use of 8-bit binary code can cover the maximum uplink rate supported by NB-IoT and the maximum uplink rate supported by NB-IoT, and the coding granularity is set to one thousand bits per second. Then, by using the coding of the evolved packet system service quality parameters, the maximum bit rate can be accurately represented.

[0112] As an optional embodiment, the maximum uplink and downlink bit rates include: a maximum uplink bit rate and a maximum downlink bit rate; the evolved packet system service quality parameters include at least: 5 bytes arranged in sequence, wherein the byte arranged in the fourth position represents the maximum uplink bit rate, and the byte arranged in the fifth position represents the maximum downlink bit rate.

[0113] In the above embodiment of the present application, the evolved packet system service quality parameter can use the fourth byte to represent the uplink maximum bit rate and the fifth byte to represent the downlink maximum bit rate, thereby realizing the use of the evolved packet system service quality parameter to represent the uplink and downlink maximum bit rates.

[0114] As an optional embodiment, in the encoding of the uplink maximum bit rate, 00000000 represents the maximum subscribed bit rate of the uplink; in the encoding of the downlink maximum bit rate, 00000000 represents a preset reserved value.

[0115] In the above embodiment of the present application, the coverage range of the 8-bit binary code is greater than the maximum uplink rate of 200kbps and the maximum downlink rate of 250kbps supported by NB-IoT. Therefore, a special value can be set for the code representing the maximum uplink and downlink bit rates, and the same code can represent different meanings for the maximum uplink bit rate and the maximum downlink bit rate. For example, for the maximum uplink bit rate, 00000000 is used to represent the maximum subscribed bit rate of the uplink link; for the maximum downlink bit rate, 00000000 is used to represent a pre-set reserved value.

[0116] Figure 4 The process of a parameter transmission method based on narrowband Internet of Things according to an embodiment of the present invention is as follows Figure 2 ,like Figure 4 As shown, the method comprises the following steps:

[0117] Step S402: The user equipment obtains a bearer activation request, wherein the bearer activation request indicates that the user equipment requests the narrowband Internet of Things to establish a dedicated data bearer, and the message format of the bearer activation request includes at least: an evolved packet system quality of service parameter and a first-level information element of an air interface message, wherein the first-level information element of the air interface message indicates a parameter of a protocol configuration option supported by the narrowband Internet of Things;

[0118] Step S404: Send a bearer activation request to the narrowband Internet of Things.

[0119] In the above embodiment of the present application, the user equipment obtains an activation bearer request, wherein the activation bearer request instructs the user equipment to request the narrowband Internet of Things to establish a dedicated data bearer, and the message format of the activation bearer request includes at least: evolved packet system service quality parameters and a first-level information element of the air interface message, the first-level information element of the air interface message represents the parameters of the protocol configuration options supported by the narrowband Internet of Things; the activation bearer request is sent to the narrowband Internet of Things, thereby achieving the purpose of reducing the encapsulation level of the parameter sub-information element, and in the activation bearer request, the encapsulation layer of the protocol configuration option PCO is deleted, and the parameters in the protocol configuration option PCO are extracted to the outermost layer of the non-access NAS message as the first-level parameters, thereby achieving the technical effect of streamlining the Internet of Things air interface parameters, and further solving the technical problem of redundancy in the Internet of Things air interface parameters based on the narrowband Internet of Things.

[0120] In the above step S402, protocol configuration options (Protocol configuration options, PCO) refer to parameters and options that can be configured or set when using a specific protocol. These parameters and options are used to adjust the behavior of the protocol to meet specific communication requirements.

[0121] Figure 5 is a schematic diagram of a message format of an initial protocol configuration option according to an embodiment of the present invention, such as Figure 5 As shown in the figure, the Protocol ID and Container ID fields in the PCO parameter format definition each occupy 2 bytes; for the 11 types of Containers in PCO, the length field occupies 2 bytes; there are a large number of Reserved bits in the Container ID definition in PCO, and among the defined non-reserved bits, a large number of Container IDs are not supported by NB-IoT.

[0122] Optionally, the 11 types of Containers in PCO are:

[0123] "NOTE:If the container ID is:

[0124] -0023H(QoS rules with the length of two octets);

[0125] -0024H(QoS flow descriptions with the length of two octets);

[0126] -0030H(ATSSS response with the length of two octets);

[0127] -0031H(DNS server security information with length of two octets);

[0128] -0032H(ECS address with the length of two octets);

[0129] -0041H(Service-level-AA container with the length of two octets);

[0130] -0051H(SDNAEPC EAP message with the length of two octets);or

[0131] -0056H(UE policy container with the length of two octets)

[0132] for network to MS direction,then the octet z+3and octet z+4indicatethe length of container ID contents.

[0133] If the container ID is:

[0134] -0041H(Service-level-AA container with the length of two octets);

[0135] -0051H(SDNAEPC EAP message with the length of two octets);or

[0136] -0056H(UE policy container with the length of two octets)
