[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the information transmission method, device, communication device and readable storage medium according to the embodiments of the present application will be described in detail with reference to the drawings according to some embodiments and their application scenarios.

[0024] Please refer to FIG. 2, which is a flow chart of an information transmission method according to an embodiment of the present application, the method being applied to a first communication device, the first communication device may be a terminal or a network side device, the network side device being, for example, a core network element, etc. As shown in FIG. 2, the method includes: It comprises a step 21 in which a first communication device sends a first message to a second communication device.

[0025] In this embodiment, the first message includes an information element container, and the information element container includes identifier information of at least one first information element and content of the at least one first information element. The identifier information can be used to identify the type of the corresponding first information element. Different first information elements have different identifier information. The identifier information of the first information element is different from the IEI of the information element IE in the related art, and the identifier information may be characteristic information of the first information element in some cases. For example, the first information element may be a network slice simultaneous registration group (NSSRG) and / or a network slice AS group (NSAG), and the identifier information and content of the NSSRG and / or NSAG can all be put into the container.

[0026] Optionally, the first information element may be a type 6 IE, including a previously defined type 6 IE and / or a newly defined type 6 IE, and may also be, but is not limited to, another type of IE.

[0027] In some embodiments, if the first information element is a type 6 IE, the corresponding information element container is a type 6 IEs container.

[0028] In some embodiments, the first communication device is a network side device, and the second communication device is a terminal, in which case the first message may be, but is not limited to, a registration accept message.

[0029] In another embodiment, the first communication device is a terminal, and the second communication device is a network side device, in which case the first message may be, but is not limited to, a 5G Mobility Management (5GMM) message, a 5G Session Management (5GSM) message, etc.

[0030] In an information transmission method according to an embodiment of the present application, a first communication device can transmit a first message to a second communication device, the first message includes an information element container, and the information element container includes identifier information and content of at least one first information element. Thus, by introducing an information element container in which identifier information of an information element is encapsulated, it is possible to distinguish different information elements without using an information element identifier IEI, achieve an effect similar to that of the information element identifier IEI, and solve the problem of IEI resource shortage in the related art.

[0031] Optionally, in order to meet the need of transmitting an information element independently without relying on an information element container, the above first message may further include an information element identifier and content of at least one second information element. For example, the second information element may be a type 6 information element (type 6 IE), and may include a previously defined type 6 IE and / or a newly defined type 6 IE. The second information element may be, but is not limited to, another type of IE.

[0032] It should be pointed out that the above first information element is an information element encapsulated in an information element container, and the above second information element is an information element outside the information element container. The above first information element and second information element may be different type 6 IEs. For example, the first information element may be a newly defined type 6 IE and the second information element may be a previously defined type 6 IE, or the first information element and the second information element may be newly defined different type 6 IEs, or the first information element and the second information element may be previously defined different type 6 IEs.

[0033] In an embodiment of the present application, the step of not sending the first message when a certain condition is not met by the first communication device and sending the first message to the second communication device includes: a step of transmitting a first message from the first communication device to the second communication device when a first condition is satisfied, the first condition being: a determination by the first communication device that at least one information element needs to be provided to the second communication device; The first communication device supports encoding and decoding of information element containers; The second communication device supports encoding and decoding of information element containers; Identifier information of at least one first information element is encapsulated in an information element container; and may include at least one of the following:

[0034] In some embodiments, the network side equipment transmits a first message to the terminal when it determines that at least one information element needs to be provided to the terminal, e.g., when it determines that at least one information element needs to be carried in a request originated at a responding terminal.

[0035] In another embodiment, the network side equipment sends a first message to the terminal when it determines that at least one information element needs to be provided to the terminal and when both the network side equipment and the terminal support encoding and decoding of information element containers.

[0036] In another embodiment, the network side device determines that at least one information element needs to be provided to the terminal, and transmits a first message to the terminal when both the network side device and the terminal support encoding / decoding for information element containers, and identifier information of the at least one first information element is encapsulated in the information element container.

[0037] In another embodiment, the terminal sends a first message to the network side equipment when the terminal determines that it needs to provide at least one information element to the network side equipment and when both the terminal and the network side equipment support encoding and decoding of the information element container.

[0038] In another embodiment, the terminal determines that it is necessary to provide at least one information element to the network side device, and transmits a first message to the network side device when both the terminal and the network side device support encoding / decoding for information element containers, and identifier information of the at least one first information element is encapsulated in the information element container.

[0039] Optionally, when at least one information element needs to be provided, if the first communication device does not support encoding / decoding for an information element container and / or the second communication device does not support encoding / decoding for an information element container, the first communication device transmits a second message to the second communication device, where the second message includes an information element identifier IEI of the at least one first information element and a content of the at least one first information element, and the second message does not include an information element container. In this way, it is possible to ensure that the transmission of relevant information to the second communication device is successful and that the encoding / decoding for the relevant information element is successful.

[0040] Optionally, to know the capability of the second communication device for the information element container, the first communication device may receive capability information from the second communication device indicating whether the second communication device supports encoding / decoding for the information element container.

[0041] Optionally, after the step of transmitting the first message, the first communication device may receive from the second communication device a first cause value for indicating a cause for the second communication device's inability to recognize the first message, for example the cause may be that the second communication device does not support encoding / decoding for the information element container.

[0042] In some embodiments, the first cause value may be transmitted to the first communication device when the second communication device provides feedback in response to the message of the first communication device. For example, the network side device may transmit the first cause value to the terminal when providing feedback in response to the terminal's message, and notify the terminal that the reason for not being able to recognize the first message is lack of support for encoding / decoding the information element container.

[0043] Optionally, if the reason why the second communication device cannot recognize the first message is that the second communication device does not support encoding / decoding for an information element container, the first communication device may transmit the IEI and content of the at least one first information element to the second communication device through a third message. For example, taking a type 6 IE as an example, when the network side device finds that the reason why the terminal cannot recognize the first message is that the terminal does not support encoding / decoding for an information element container, the network side device may transmit the type 6 IE that is included in the information element container and is not recognized by the terminal to the terminal through a message such as a terminal configuration update (e.g., UE configuration update, UCU) or a downlink non-access stratum transmission (e.g., DL NAS TRANSPORT).

[0044] Optionally, a timer for replying that the first message is confirmed may be introduced to ensure the successful reception of the first message. During the step of transmitting the first message, the first communication device may start a first timer (time), which is a timer for the second communication device to reply that the first message is confirmed, and if the first communication device does not receive a fourth message from the second communication device for replying that the first message is confirmed before the first timer times out, the first communication device may retransmit the first message to the second communication device so that the second communication device obtains related information, or if the first communication device receives a fourth message from the second communication device for replying that the first message is confirmed before the first timer times out, the first communication device may stop the first timer. For example, the fourth message may be a Registration complete message.

[0045] Optionally, said information element container may include at least one of an information element identifier of the information element container and a length indicator of the information element container, such that the information element identifier of the information element container allows different information element containers to be distinguished, and the length of the information element container allows the length of the contents of the information element container to be known.

[0046] In some embodiments, when the information element container is a type 6 IEs container, the information element identifier of the type 6 IEs container may be "comprehension required" or non-"comprehension required".

[0047] In some embodiments, when the information element container is a type 6 IEs container, the information element identifier of the type 6 IEs container may use the IEI of the existing type 6 IE "comprehension required", for example, by setting the IEI to one of 7C to 7F, thereby meeting the transmission needs without changing the protocol architecture of the related technology.

[0048] In another embodiment, when the information element container is a type 6 IEs container, the information element identifier of the type 6 IEs container is set to an available non-“comprehension requirement” IEI, for example, the IEI is set to any one of 70, 71, and 7B, and then the IEs of the remaining two IEI identifiers and a type 6 IE that will be newly defined later may all be encapsulated in the type 6 IEs container, or may not be encapsulated in the type 6 IEs container and still be transmitted in the registration accept message.

[0049] Optionally, the information element container may further include a length and a value of at least one first information element.

[0050] Optionally, the above information element container may have different implementation manners, which are described as follows:

[0051] Method 1: In method 1, the information element container includes contents of the information element container, the contents of the information element container include the number of first information elements in the information element container and information of each first information element in the information element container, and the information of each first information element includes identifier information of each first information element, the length of each first information element, and the contents of each first information element.

[0052] For example, referring to FIG. 3A , taking the information element container as an example being a type 6 IEs container, the type 6 IEs container may include a type 6 IEs container IEI, a length of the contents of the type 6 IEs container (e.g., Length of type 6 IEs container contents), and contents of the type 6 IEs container (e.g., type 6 IEs container contents).

[0053] Furthermore, as shown in FIG. 3B, the type 6 IEs container contents may include, but are not limited to, the number of type 6 IEs contained in the type 6 IEs container (i.e., i below) and information on each type 6 IE in the type 6 IEs container, such as type 6 IEs container entry 1, type 6 IEs container entry 2, ..., type 6 IEs container entry i (i is a positive integer; in FIG. 3B, for example, the number of type 6 IEs is i).

[0054] Furthermore, as shown in Fig. 3C, the information of each type 6 IE in the type 6 IEs container may include identifier information of the type 6 IE (e.g., type of type 6 IEs), the length of the content of the type 6 IEs (e.g., Length of type 6 IEs container entry), and the content of the type 6 IEs (e.g., Value of type 6 IEs container entry). The identifier information of the type 6 IE is for indicating the type 6 IE carried in the corresponding container.

[0055] In some embodiments, the type of type 6 IEs may contain 8 bits of information, for example 00000000 is for spare and 00000001 indicates that the container is carrying NSAG information.

[0056] Method 2: In method 2, the information element container includes an information element indication list and contents of the information element container, the information element indication in the information element indication list is used to indicate whether the information element container includes a first information element corresponding to the information element indication, and the contents of the information element container include information of each first information element in the information element container, and the information of each first information element includes identifier information of each first information element, the length of each first information element, and the contents of each first information element.

[0057] For example, referring to FIG. 4A , taking the information element container as an example of a type 6 IEs container, the type 6 IEs container may include a type 6 IEs container IEI, a length of the type 6 IEs container contents, an information element indication list (type 6 IEs container IEs list), and type 6 IEs container contents.

[0058] Furthermore, as shown in FIG. 4B, the type 6 IEs container IEs list may include, but is not limited to, IE instructions Ind 8, Ind 7...Ind 1. The IE instructions are used to indicate whether the type 6 IE corresponding to the IE instructions is included in the type 6 IEs container. For example, the value of the IE instruction may be 0 or 1, and when it is 0, it indicates that the type 6 IE corresponding to the type 6 IEs container is not included, and when it is 1, it indicates that the type 6 IE corresponding to the type 6 IEs container is included. For example, when the value of Ind 8 is 1, it indicates that the type 6 IE corresponding to Ind 8 is included in the type 6 IEs container, when the value of Ind 7 is 0, it indicates that the type 6 IE corresponding to Ind 7 is not included in the type 6 IEs container, and when the value of Ind 1 is 1, it indicates that the type 6 IE corresponding to Ind 1 is included in the type 6 IEs container...

[0059] Furthermore, as shown in FIG. 4C, it indicates type 6 IEs included in a type 6 IEs container. For example, a type 6 IEs container includes type 6 IE information 1 (e.g., Ind 1 container entry, i.e., a type 6 IE corresponding to Ind 1), type 6 IE information 4 (e.g., Ind 4 container entry, i.e., a type 6 IE corresponding to Ind 4) ... and type 6 IE information j (e.g., Ind j container entry, i.e., a type 6 IE corresponding to Ind j) (j is a positive integer). However, j in FIG. 4C does not indicate the number of type 6 IEs in a container, but indicates that a type 6 IE j is included in the container. For example, Ind 1 may be used to indicate whether NSAG information is carried in a type 6 IEs container. For example, when the value of Ind 1 is 0, it indicates that NSAG information is not carried, and when the value of Ind 1 is 1, it indicates that NSAG information is carried.

[0060] Furthermore, as shown in Fig. 4D, the information of each type 6 IE in the type 6 IEs container may include identifier information of the type 6 IE (e.g., type of type 6 IEs), the length of the content of the type 6 IEs (e.g., Length of type 6 IEs container entry), and the content of the type 6 IEs (e.g., Value of type 6 IEs container entry). The identifier information of the type 6 IE is for indicating the type 6 IE carried in the corresponding container.

[0061] The present application will be described below by means of drawings and specific cases.

[0062] Case 1 In this case 1, the IEI of the type 6 IEs container is a "comprehension requirement", for example, any one of IEIs 7C to 7F of the type 6 IE. As shown in FIG. 5, the information transmission process includes the following steps:

[0063] S1: A terminal UE sends a request message to a network side device, and capability information is carried in a 5GMM capability IE of the request message, and the capability information is for indicating whether the terminal supports encoding and decoding for a type 6 IEs container. If the terminal supports encoding and decoding for a type 6 IEs container, it indicates that the terminal can recognize and successfully encode and decode the Type 6 IEs container. If the terminal does not support encoding and decoding for a type 6 IEs container, it indicates that the terminal cannot recognize the Type 6 IEs container issued by the network side device and cannot complete encoding and decoding of the container.

[0064] S2: After receiving the capability information, the network side device performs one of the following operations based on the capability of the terminal and the capability of the network side device:

[0065] S21: If the network side device supports encoding / decoding for a type 6 IEs container and determines that one or more Type 6 IEs need to be returned to the terminal in a response message, and the terminal supports encoding / decoding for a type 6 IEs container, the network side device encapsulates one or more Type 6 IEs in the type 6 IEs container and indicates identifier information of the Type 6 IEs carried in the container in the type 6 IEs container, and the network side device performs one or more of the following operations:

[0066] 1) Send a response message, where the response message includes a type 6 IEs container, and the response message may further include at least one of one or more previously defined Type 6 IEs, one or more newly defined Type 6 IEs, and other IEs.

[0067] 2) The first timer is started, which is a timer for the terminal side to reply that it has acknowledged the message. After the timer times out, if the network side determines that the terminal has not received the response message, it will send the response message again.

[0068] S22: When the network side device determines that one or more Type 6 IEs need to be returned to the terminal in a response message, but the terminal does not support encoding / decoding for a type 6 IEs container, the network side device may not carry a type 6 IEs container in the response message sent to the terminal, and the response message may include at least one of one or more previously defined Type 6 IEs, one or more newly defined Type 6 IEs, and other IEs.

[0069] S23: If the network side device does not support encoding / decoding for the type 6 IEs container, the network side device does not carry the type 6 IEs container in the response message sent to the terminal.

[0070] S3: The network side device sends a response message including, for example, a type 6 IEs container to the terminal.

[0071] S4: Upon receiving the response message, the terminal performs the following operations:

[0072] If the terminal supports encoding and decoding of the type 6 IEs container, it decodes the type 6 IEs container to obtain one or more Type 6 IEs, and then returns a completion message (i.e., the above-mentioned fourth message) to the network side device to confirm the successful transmission and decoding of the container to the terminal on the network side and to stop the first timer.

[0073] - If the terminal does not support encoding / decoding for a type 6 IEs container, it ignores the relevant fields when decoding, and ignoring the relevant fields includes ignoring 1+2+length bytes, where 1 byte indicates the length of the IEI of the Type 6 IEs container, 2 bytes indicates the length of the LI of the Type 6 IE, and length indicates the length of the value after it is displayed in the LI field.

[0074] S5: Optionally, if the network side device does not receive a completion message returned by the terminal before the first timer times out, it repeatedly sends the response message in S3, and when the number of repeated transmissions reaches a predetermined maximum number, it stops sending the response message and stops the first timer.

Compared with case 1, the difference is mainly in modifying the IEI of the Type 6 IEs in the related art to 70, 71, and 7B, one of which can be used for the Type 6 IEs container, and the remaining two can be put into the container, or they can remain in the response message and use the assigned IEI. As shown in Figure 5, the information transmission process includes the following steps:

[0078] S1: Same as S1 in Case 1.

[0079] S2-S4: If the network side device supports encoding / decoding for a type 6 IEs container and the terminal supports encoding / decoding for a type 6 IEs container, the network side device encapsulates Type 6 IEs, such as a Service-Level-AA container, NSSRG information, an Extended Closed Access Group (CAG) information list, and / or a newly defined type 6 IE, into a type 6 IEs container, indicates the type of Type 6 IE carried in the container in the type 6 IEs container, and sends the type 6 IEs container to the terminal in a response message.

[0080] In particular, when all of the following conditions are satisfied: 1) the network side device supports encoding and decoding for type 6 IEs container; 2) at least one of the three IEs, Service-level-AA container, NSSRG information, and Extended CAG information list, is encapsulated in a type 6 IEs container; and 3) the network side device determines that at least one of the three IEs, Service-level-AA container, NSSRG information, and Extended CAG information list, needs to be returned to the terminal, the network side device optionally performs the following operations.

[0082] 2) The first timer is started, which is a timer for the terminal side to reply that it has acknowledged the message. After the timer times out, if the network side determines that the terminal has not received the response message, it will send the response message again.

[0083] If the terminal supports encoding / decoding for a type 6 IEs container but the network side device does not support encoding / decoding for a type 6 IEs container, the network side device does not carry the type 6 IEs container in the response message.

[0084] S5-S7: Same as S5-S7 in Case 1.

[0085] Case 3 In this case 3, the terminal sends a type 6 IEs container to the network side device. As shown in Figure 6, the information transmission process includes the following steps:
