Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to an information transmission method, device, multi-card terminal and readable storage medium. Background Art

[0002] Currently, there are not only single-card terminals but also dual-card or multi-card terminals on the market, collectively referred to as multi-card terminals. The capabilities of multi-card terminals can be single-send single-receive, single-send dual-receive, and dual-send dual-receive.

[0003] One feature of a multi-card terminal is that it can reside on multiple networks at the same time, but the implementation methods of multi-card terminals are different. Some multi-card terminals can send and receive on multiple networks at the same time without affecting each other. However, there is also a type of multi-card terminal that, although the terminal can reside on multiple networks at the same time, may reside on two networks in a time-division manner, that is, it resides on network A for a period of time to listen to network A's paging, and resides on network B for a period of time to listen to network B's paging; or it connects to network A for a period of time to send and receive data, and it needs to go to network B for a period of time to receive paging; or it receives data on network A for a period of time, and it needs to establish a connection or send and receive data on network B for a period of time. Existing multi-card terminals include idle UEs and connected UEs. When an idle UE needs to access the network to transmit information, it may interrupt the connection and data transmission of another UE in connected mode.

[0004] In a multi-SIM terminal, when an idle UE needs to access the network to transmit information, it will interrupt the connection and data transmission of other UEs in connected mode. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide an information transmission method, which can solve the problem that when an idle UE needs to access the network to transmit information in a multi-card terminal, the connection and data transmission of the connected UE will be interrupted.

[0006] In order to solve the above technical problems, this application is implemented as follows:

[0014] The first network is a network where the first UE resides, the first information includes an information type that supports non-3GPP transmission, and the information type of the second information belongs to the information type that supports non-3GPP transmission.

[0015] In a third aspect, a multi-card terminal is provided, which includes a first UE and a second UE. The multi-card terminal also includes a processor, a memory, and a program or instruction stored in the memory and executable on the processor. When the program or instruction is executed by the processor, the steps of the method described in the first aspect are implemented.

[0016] In a fourth aspect, a readable storage medium is provided, on which a program or instruction is stored. When the program or instruction is executed by a processor, the steps of the method described in the first aspect are implemented.

[0017] In a fifth aspect, a chip is provided, comprising a processor and a communication interface, wherein the communication interface is coupled to the processor, and the processor is used to run a network-side device program or instruction to implement the steps of the method described in the first aspect.

[0018] In the embodiment of the present application, the first UE first determines that the first information supports non-3GPP transmission, and then transmits the second information to the first network where it resides through the data connection of the second UE in a non-3GPP transmission mode, wherein the first information indicates the information type of the second information. In this way, for the determined information type, the idle or inactive UE can transmit information to the network in a non-3GPP transmission mode through the data connection of the connected UE, thereby avoiding interrupting the connection and data transmission of the connected UE.

[0028] In order to better understand the solution provided by the embodiment of the present application, the following contents are first introduced:

[0029] See also Figure 1The figure shows that the terminal can access the fifth generation communication technology (5 th The non-3GPP network accesses the 5G network through the non-3GPP InterWorking Function (N3IWF).

[0030] The information transmission method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0031] See also Figure 2 The embodiment of the present application provides an information transmission method, which is applied to a multi-card terminal, the multi-card terminal includes a first UE and a second UE, and the method includes:

[0032] Step 201: A first UE determines first information supporting non-3GPP transmission;

[0033] Step 202: The first UE sends second information to the first network through the data connection of the second UE in a non-3GPP transmission manner, and / or receives second information from the first network in a non-3GPP transmission manner;

[0034] The first network is a network where the first UE resides, the first information includes an information type supporting non-3GPP transmission, and the information type of the second information belongs to the information type supporting non-3GPP transmission.

[0035] In the embodiment of the present application, the first UE first determines the first information that supports non-3GPP transmission, that is, determines the type of information that supports non-3GPP transmission, and then transmits the second information to the first network through the data connection of the second UE in a non-3GPP transmission mode for the determined information type. It should be noted that the second information includes information in the bidirectional transmission process with the first network, that is, the second information includes information sent by the first UE to the first network through the data connection of the second UE in a non-3GPP transmission mode, or information received by the first UE from the first network through the data connection of the second UE in a non-3GPP transmission mode.

[0036] In some implementations, the first UE is in an idle state or an inactive state, and the second UE is in a connected state. In this way, for a certain information type, the idle or inactive UE can transmit information to the network in a non-3GPP transmission mode through the data connection of the connected UE, thereby avoiding interrupting the connection and data transmission of the connected UE.

[0037] With respect to step 201 above, in some implementations, the first UE determines the first information supporting non-3GPP transmission, including:

[0038] The first UE sends first information to the first network, where the first information includes: an information type supporting non-3GPP transmission, that is, the first UE sends the information type supporting non-3GPP transmission to the first network;

[0039] In an embodiment of the present application, the first UE determines, based on its own capabilities, the type of information that it supports for non-3GPP transmission, and sends the determined type of information to the first network.

[0040] Alternatively, the first UE receives first information from the first network, where the first information includes: an information type supporting non-3GPP transmission, that is, the first UE receives from the first network an information type that the first network supports non-3GPP transmission;

[0041] In the embodiment of the present application, the first network configures the information type supporting non-3GPP transmission for the first UE based on the information type supporting 3GPP transmission by itself.

[0042] In this way, the first UE negotiates with the first network about the information types supported by non-3GPP transmission, thereby being able to determine which types of information can be transmitted in a non-3GPP transmission manner.

[0043] It should be noted that, in some implementations, the first information may also be referred to as multi-card auxiliary information or UE auxiliary information.

[0044] Furthermore, for the above two methods of the first UE determining to support non-3GPP transmission of the first information, the first UE may transmit the first information to the first network using a 3GPP transmission method or a non-3GPP transmission method, that is, the first UE may send the first information to the first network via a 3GPP transmission method or a non-3GPP transmission method, or the first UE may receive the first information from the first network via a 3GPP transmission method or a non-3GPP transmission method.

[0045] In some implementations, the information type supported for non-3GPP transmission includes at least one of the following:

[0046] Paging message type;

[0047] Non-access stratum (NAS) signaling message type;

[0048] Radio Resource Control (RRC) signaling message type;

[0049] Short Message Service (SMS) type;

[0050] Paging response type;

[0051] Paging busy indication type.

[0052] That is, the first UE may transmit the above-mentioned type of second information to the first network through the data connection of the second UE in a non-3GPP transmission manner.

[0053] In some implementations, the first information includes any one of the following:

[0054] NAS messages;

[0055] Information elements of NAS messages;

[0056] RRC message;

[0057] Information element of RRC message.

[0058] That is, the first UE may send the first information in the above format to the first network, or receive the first information in the above format from the first network.

[0059] Further, in some implementations, the type of information that the first network supports non-3GPP transmission, received by the first UE from the first network, includes at least one of the following:

[0060] (1) The first UE receives system information from the first network, and determines, according to the system information, the type of information supported by the first network for non-3GPP transmission;

[0061] In an embodiment of the present application, the first network configures the first information for the first UE through system information, and the first UE determines the information type supported by the first network for non-3GPP transmission by reading the system information.

[0062] (2) The first UE receives a registration completion message from the first network, and determines, according to the registration completion message, the type of information supported by the first network for non-3GPP transmission;

[0063] In an embodiment of the present application, the first network configures the first information for the first UE through a registration completion message, and the first UE determines the information type supported by the first network for non-3GPP transmission by receiving the registration completion message.

[0064] (3) The first UE receives network assistance information from the first network, and determines, according to the network assistance information, the type of information supported by the first network for non-3GPP transmission;

[0065] In an embodiment of the present application, the first network configures the first information for the first UE through network auxiliary information, and the first UE determines the type of information supported by the first network for non-3GPP transmission by receiving the network auxiliary information.

[0066] With respect to the above step 202, in some implementations, the first UE transmits the second information via the data connection of the second UE through the N3IWF and the Access and Mobility Management Function (AMF) of the first network.

[0067] The transmission process of the second information is described below for different first information, that is, for different types of second information:

[0068] Example 1: The first information includes: a paging message type, a NAS signaling message type, an SMS type, and / or a paging response type, and the second information transmitted with the first network includes at least one of the following:

[0069] Initiate a periodic registration update, send a first request message to the first network, and receive a first response message from the first network;

[0070] Initiate a Tracking Area Update (TAU), send a second request message to the first network, and receive a second response message from the first network;

[0071] Initiate a location area update (LAU), send a third request message to the first network, and receive a third response message from the first network;

[0073] receiving a paging message from a first network;

[0074] sending a paging response to the first network;

[0075] It should be noted that in actual application, after receiving the paging message, the first UE may not continue to send a paging response to the first network using a non-3GPP transmission method. Therefore, the above-mentioned process of transmitting the second information may only include the operation of receiving a paging message from the first network.

[0076] Example 2: The first information includes: an RRC signaling message type, and the second information is transmitted with the first network, including at least one of the following:

[0077] Initiating a periodic radio access network notification area update (RAN Notification Area Updating, RNAU), sending a fifth request message to the first network, and receiving a fifth response message from the first network;

[0078] System information is received from the first network.

[0080] receiving a paging message from a first network;

[0081] Sending paging busy indication information to the first network, where the paging busy indication information is used by the UE to inform the network that it does not respond to paging and will not continue the connection establishment process required by subsequent paging reasons.
